Description

The present invention relates to a wind turbine according to the preamble of claim 1.

Common to the known from the prior art wind turbines and methods for wind energy use that the rotors are arranged vertically. A disadvantage of all known systems and methods is low efficiency or efficiency compared to systems with horizontal rotors. The efficiency of Darius rotors lies in the top at 75% of the efficiency of modern wind turbines with horizontal rotor axis. Lower efficiency leads to higher prices and costs of electricity production. Since a part of the rotor blades must always move against the wind, they also have an aerodynamic disadvantage compared to horizontal systems. This leads to hurdles and more uneven loads than with modern horizontal axles. The recent vertical runners run heavy on their own and often need external energy to start operations. Another disadvantage is the power regulation. Horizontal systems can be turned out of the wind direction in strong wind. With vertical runners can quickly overload, because this is not possible.

The alternative, wind turbines with horizontal rotors (HAWT: Horizontal Axis Wind Turbine) are very controversial in the population. As drawbacks are called by critics shadow, disco effect, obstacle lights, wind noise, landscape deterioration and tourism impact. The development of HAWT systems leads to ever larger masts and rising costs. The maintenance costs for spare parts, repairs and service work also entail very high costs and can only be handled by large corporations and specialist companies as well as specialist specialists. Large systems also involve major design and loading problems. As a result, they have a much larger space requirement and increasingly burden the environment. Repowering, which replaces several small plants with one large wind turbine at the same site, also creates unnecessary additional burdens for society and the environment.

Until now, vertical wind turbines could not prevail over HAWT systems due to the above mentioned reasons. Also, they could not be built in the comparable dimensions and provide no comparable performance or energy yield.

The present invention is therefore based on the object to provide a wind turbine, which combines the advantages of the vertical rotor principle with a higher energy yield and efficiency. In addition, it is an object of the present invention to provide a wind turbine, which has a smooth running and is quiet.

This is inventively achieved by a wind turbine according to the independent claim 1 and by a method for wind energy utilization according to the independent claim 12. Advantageous embodiments and further developments are the subject of the dependent claims.

The wind power plant according to the invention comprises a substantially vertically oriented central support for receiving at least one rotor frame frame arranged movably thereon and at least two rotors arranged rotatably with at least one rotor frame frame with essentially vertical rotation axis. Preferably, the central carrier is aligned exactly vertically.

Preferably, the central carrier is rod-like, more preferably conical and / or cylindrical. If the central support is conical, then its cross-section tapers in the direction of the upper free end. Furthermore, it is preferred that the central carrier is formed of metal, for example of steel. The system is not limited to this material. Also conceivable is an embodiment of aluminum or of other materials known from the prior art.

It has been found that an at least partially hollow central support is particularly suitable for use in the invention described herein. In the internal cavity of the central support stairs or electrical means of transport may be provided to transport maintenance personnel or material. For this purpose, the central carrier advantageously has at least one continuous jacket opening, for example a passage in the form of a door, in order to reach the outside and / or vice versa from the interior of the central carrier. Depending on the training preferably two or more continuous shell openings are provided. Depending on the application of the central support can be formed as advantageous as a tower or mast.

The core idea of the present invention consists in that the at least one rotor frame frame comprises a plurality of frame elements, wherein at least one frame element, preferably two frame elements, is (are) formed as rotor armature element (s) and the rotor frame frame is rotatably mounted about a substantially vertical axis on the central support is arranged and the rotors are rotatably arranged on the at least one rotor carrier element. This is advantageous, especially if the rotor carrier element is directly adjacent is arranged to the upwardly directed free end of the central carrier. In this case, a hanging construction principle is achieved, so that the upper free end of the central support keeps the rotor support member rotatable about at least one pivot bearing. This allows a very simple structure and basically the construction of very high and very stable and safe preferred vertical wind turbines, which was not possible with the prior art until today. Furthermore, this compact and simple design allows a reduction in manufacturing costs compared to known systems. In addition, the production with a lower workload and a faster and more cost-effective transport of the individual wind turbine components is possible.

Substantially vertical is here preferably understood to mean a deviation of 0 ° to 25 ° from the vertical.

Particularly advantageous in this context is the formation of the at least one rotor carrier element as a rotor carrier plate, whereby a particularly good attachment of the rotors by means of rotary bearings and a uniform distribution of forces is made possible. Further preferably, two rotor carrier elements are designed as rotor carrier plates. This is advantageous because thus the rotors are connectable at their two free ends with the rotor carrier plates. This serves to stabilize the entire system. Preferably, the rotor carrier elements are designed as upper and / or lower rotor carrier plate which limits the rotor frame frame upwards and / or downwards. Of course, the training as a plate is not restrictive to understand, but thought only in its geometric shape. Thus, the rotor carrier element may be plate-like and / or also scaffold-like. Under plate-like is to be understood here that the individual elements have a significantly greater extent in their length and width, as in their height. It is not necessarily necessary that the plate-like frame members are formed with a continuous surface as a solid component. Thus, in the framework-like construction, it is conceivable that the plate-like elements and / or the rotor carrier plates are formed as cross braces of, for example, tubes and / or solid components with continuous openings therebetween.

In a further advantageous embodiment, the rotors are each arranged rotatable about an axis of rotation on the at least one rotor carrier element, wherein the axes of rotation substantially parallel, preferably inclined to each other, more preferably an angle between 0 ° -60 °, more preferably 0.5 ° -30 °, most preferably 1 ° -15 ° enclosing, are arranged. This is a clear difference from the known state of the art, in which the rotors are always arranged vertically and parallel to one another. Due to the inclination of the two rotors to one another against the wind flow and the free end of the central support inclined arrangement is formed. Preferably, the two axes of rotation are inclined to each other such that the spacing of the rotors decreases toward one another in the direction of the free end of the central carrier. Depending on the height of the central support of the included angle of the two axes of rotation is variable, wherein it has been found that an angle of 0 ° to 60 °, preferably in the range of 0.5 ° to 30 °, more preferably in the range of 1 ° to 15 °, wherein it has proved most advantageous to form the angle of inclination of the axes of rotation to each other at 5 ° 6 °, 7 ° 8 ° 9 °, 10 °, 11 ° or 12 °, as this brings the most effective power output with it. At an angle of 0 ° is to be understood that the rotors are arranged parallel to each other. Of course, this is not limiting, so that it is also possible to arrange the two rotors parallel to each other. Thus, it is conceivable that the rotors are indeed parallel to each other, but nevertheless formed in a predeterminable angle of inclination with respect to the central carrier. For example, it is conceivable that both rotors have the same inclination angle to the central support and this is preferably formed in the range of 0.5 to 30 °. Furthermore, it is also conceivable that both the rotors are inclined relative to one another in the abovementioned angle data and at the same time are inclined towards the central support. Advantageously, in this embodiment, the two rotors have the same angle of inclination, preferably in the range of 0.3 to 30 °, to the central support.

Furthermore, it is conceivable that the rotors have different diameters in the different spaces between the rotor carrier elements. Preferably, the diameters are decreasing towards the top. This design has the consequence that the rotor axes have a against the wind flow and the central support tip inclined position. This gives the entire system an upwardly tapering shape.

In a further advantageous embodiment, the at least one rotor frame frame is arranged suspended and / or rotatable on the central carrier. Advantageously, the arrangement is designed as a storage. This is advantageous, since thus the leverage forces acting on the tower head, as known from the prior art, can be significantly reduced in the present invention. Due to the suspended mounting of the wind turbine, the tower head masses are displaced so that induced vibrations and resonances are reduced. Furthermore, the hanging storage of the rotor frame frame proves to be advantageous because the For example, wind turbine can be easily deflected optimally in the wind direction with a wind vane and the resulting simple rotary mechanism with low energy consumption.

Due to the special suspension of the rotor frame frame via a thrust bearing and / or pivot bearing material stress and fatigue of the individual components of the wind turbine is significantly reduced, so that a material wear is reduced and material overstress is reduced. Consequently, the wind turbine described here is less expensive and significantly longer in their life and service life.

Preferably, the at least one rotary bearing, by means of which the rotor frame frame is in communication with the central support, is designed as a radial bearing. Of course, this is not restrictive, so that it is also conceivable that at least one bearing is designed as a thrust bearing or in a particularly preferred embodiment as a combined radial / thrust bearing. In addition, the use of a magnetic bearing is advantageous, since this leads to the minimization of wear.

Moreover, it is advantageous that the rotors are arranged in the air flow direction behind the central support. This is preferred because the central support and in the direction of air flow preferably arranged in front of the airflow divide the impinging air flow, shield against the air flow running rotor blades from the air flow and redirect the air flow to the outside rotor blades. The air guide surfaces are preferably attached to their own holding elements.

Preferably, a rotor frame frame further Lufttleitelemente perpendicular to the air flow direction laterally outside. These serve to compress air and increase the amount of air impinging on the rotor blades. This is particularly advantageous in wind-poor regions.

It is conceivable that the rotor frame frame additionally comprises further frame elements, which are preferably plate-like and / or rod-like or in any other arbitrary shape. Under plate-like is to be understood here that the individual elements have a significantly greater extent in their length and width, as in their height. It is not necessarily necessary that the plate-like frame members are formed with a continuous surface as a solid component. For example, it is conceivable to provide the plate-like frame elements as individual, permanently connected cross struts. Depending on the size of the wind turbine, the shape of the plate-like frame elements is freely selectable. Common to all plate-like elements is that at least two, preferably three, continuous openings are provided. The openings are formed such that the rotors and the central support can be easily passed through them. Consequently, the openings are always formed larger than the rotors or the central carrier.

In addition, it is conceivable that, in particular at high wind turbines of greater than 50 m, the openings of the plate-like frame members are formed such that an insertion aid is provided. An insertion aid is advantageous, so that not the entire rotor from bottom to top must be performed through the corresponding openings of the plate-like frame members. Advantageously, each of the openings for rotor reception comprises at least one insertion aid. This is furthermore preferably designed as an insertion opening, which advantageously has a smaller diameter than the openings themselves. The rotors or the rotor core segments can thus be introduced easily and quickly laterally from the outside into the corresponding openings of the plate-like frame elements.

The plate-like frame members preferably have a triangular circumference, wherein the side surfaces may be formed linear or convex outwardly curved. This preferably curved geometric shape of the plate-like frame elements has proven to be advantageous for the flow line of the incoming air. The plate-like frame elements can also be designed as tubes and / or T-beams.

Furthermore, at least one spacing frame element is preferably also included. The at least one spacing frame element is advantageously designed for spacing the individual plate-like frame elements or the rotor carrier elements from one another. Preferably, in each case two plate-like frame elements or a plate-like frame element and a rotor carrier element of at least two, preferably at least three, spaced apart frame elements spaced from each other. The at least one spacing frame element is in this case firmly connected to the plate-like frame elements or the rotor carrier element. Advantageously, the at least one spacing frame element is rod-like. However, it is also conceivable that the at least one spacing frame element is plate-like or has another advantageous shape. It is conceivable that the holding elements of the air guide surfaces are formed as a spacing frame elements. Furthermore, it is conceivable that here further aerodynamic air guide surfaces are formed as a spacing frame elements. Preferably, between each two rotor support elements and / or between two plate-like frame members and / or between a plate-like frame member and a rotor support plate each 1-5, more preferably 2-4, more preferably arranged 3 spaced frame members. They advantageously form a support connection. Further preferably, they are advantageously designed as rod-like, spacing frame elements as mutually parallel vertical struts. More preferably, they have an identical distance from each other. Furthermore, it is conceivable that they are arranged in a polygonal shape around the rotors.

In the longitudinal extent of the rotor frame frame, it has also proven to be advantageous to provide a plurality of plate-like frame members, which are arranged spaced apart from each other via spaced frame members.

Due to the inclination of the rotors also an overall conical shape of the rotor frame frame is conditional, to the effect that the mutually parallel spaced plate-like frame members in their circumference upwards, ie in the direction of the free end of the central support, are tapered.

In addition, in this way preferably results in a conically upwardly converging shape that allows a particularly effective use of the impinging air flow. The suspended structure on a continuous central support is advantageous over embodiments of the prior art, in which the rotor housing is arranged, for example, standing on a lower mast. In the wind turbine described here vibration is avoided. The structure can be much slimmer and higher. Furthermore, an improved efficiency is achieved precisely because of the upwardly tapering shape. The existing area is used optimally. It is also conceivable that the central carrier tapers conically upwards. In addition, a more even wind pressure is achieved on the entire wind turbine. Advantageously, the upwardly tapering shape or the angle of inclination of the central carrier and / or the rotors to one another and / or to the central carrier is determined in particular by the height of the wind turbine and the location of use.

The design of the at least one spacing frame element is not to be understood as limiting, so that this spacing frame element can preferably be cylindrical and / or square. Furthermore, it is also conceivable that, instead of the spacing frame element, further plate-like frame elements are formed as spacers between the above-described substantially horizontally arranged plate-like frame elements.

Depending on the embodiment, the rotor frame frame is formed in the simplest case by an upper and a lower rotor support plate on which preferably two mutually opposite rotors are arranged stored. For additional stabilization, at least one spacing frame element, preferably rod-shaped, can additionally connect the two rotor carrier plates to one another. If, however, in addition to the rotor carrier plates further plate-like frame members, preferably designed as a floor panels, provided, these serve in particular the stabilization, centering and the simplified maintenance of the rotors and / or the frame. The floor panels can be connected to each other or with the rotor carrier plates by spaced frame members. It is conceivable that both the floor panels and the upper and lower rotor support plate are inclined. Advantageously, an inclination angle of 0 ^ -60 °, more preferably 0.5 ° -30 °, more preferably 1 ° -15 °. This inclination advantageously corresponds to the inclination of the rotors to the central support. Further preferably, the floorboards and the rotor support plate between the rotors to a kink or a curvature, both sides each having an inclination angle of 0 ° -60 °, more preferably 0.5 ° -30 °, more preferably 1 ° -15. In this way, a plane of a portion of a rotor carrier plate or a floor plate, which surrounds a rotor disk, advantageously aligned parallel thereto. Preferably, the plate-like frame members are parallel to each other, and arranged substantially horizontally. Further preferably, the plate-like frame members are accessible, so that maintenance and repair of the rotors can be performed simplified. Depending on the size of the wind turbine, this preferably comprises 1 to 20, more preferably 2 to 10 and most preferably 3 to 8 plate-like frame elements. Further advantageously, these plate-like frame members are arranged at a distance of 1 to 20 m, more preferably at a distance of 2 to 10 m.

In order to reduce tilting or friction between rotors and frame on the one hand and between plate-like frame members and central support on the other hand and to avoid at best, are at the respective openings of the plate-like frame members, in which rotors and / or the central carrier are feasible, preferably three to twelve, more preferably three to seven, most preferably in each case three, guide elements arranged. Preferably, the guide elements are formed cylindrically with at least one curved guide surface. By way of example, three guide elements per guide for guiding the Rotors in the frame and / or the frame on the central support at a distance of 120 ° to each other. Advantageously, the distance between the guide elements to one another varies depending on their number, wherein the distances between each guide elements arranged adjacent to each other is the same. The guide elements are preferably designed as guide rollers or guide cylinders and are formed at least on the guide surface, preferably completely, of elastic material. The material is chosen to have some residual rigidity. If, for example, the rotor frame frame is subjected to very strong wind, a certain deflection can take place about the axis of rotation of the central carrier, so that, for example, the edges of the openings of the plate-like elements are guided against the central carrier. The arranged at the edges guide elements serve the acting force absorption and dissipation and at the same time the damping of the deflection movement. Thus, the material is spared. In addition, the guide elements are designed such that they have a sound-insulating property and absorb, absorb and / or dissipate noises and vibrations.

Advantageously, the guide elements are designed such that they preferably guide and align the rotor frame around the central support. Further preferably, they also carry the rotors in the frame.

In a further advantageous embodiment, the at least one rotor frame frame comprises at least one rotor carrier element, at least one spacing frame element and preferably at least one plate-like frame element, advantageously a floor plate. This is advantageous since, as already stated, plate-like frame elements are vibration-damping, so that this absorbs part of the forces acting on the rotor (s). At least one spacing frame member also advantageously provides stabilization of a rotor frame.

In a further advantageous embodiment, the at least one spacing frame element for spacing the rotor carrier plates and / or the plate-like frame elements and / or the plate-like frame elements of the rotor carrier plates rod-like, plate-like or aerodynamic Luftleitfläche. Rod-like spaced frame members are advantageous because they are material-saving and yet stabilize the rotor frame frame effectively. Plate-like rotor frame elements are advantageous because they not only stabilize against a tensile and compressive stress, but also against a shear stress. Aerodynamic air guide surfaces are advantageous because they combine the function of guiding a Anströmluftflusses with a stabilizing effect on the rotor frame frame.

In a further advantageous embodiment, the rotors each comprise at least one rotor core segment, preferably a plurality of rotor core segments, between a first and a further rotor carrier element arranged at a distance therefrom. Depending on the embodiment, the rotor core segments can be understood as segmented waves or as a common, continuous drive shaft. At high wind turbines of 20m and more, it has been found advantageous to provide multiple rotor core segments, as this subdivision provides additional stability to the entire rotor and stabilizes against external vibrations and resulting material vibrations. It is conceivable that the rotor core segments taper in a pyramidal manner towards the top, thus decreasing in their diameter. This causes a conical or pyramidal extent.

If the rotor is formed in one piece, the rotor core segment corresponds to the rotor core and thus to a continuous drive shaft. If the rotor comprises a plurality of rotor core segments, these form at least the rotor core in the assembled state. Preferably, the rotor core segments can be understood as modules, which can be connected to one another in any desired number, in order to vary the length and the diameter of the resulting rotor. For simplified mounting to each other and / or on the rotor support elements each rotor core segment comprises at least one, preferably two, each end arranged projections, which are preferably designed as end pin. A pin is advantageous opposite to a depression in the adjacent rotor core segment, with the mating is possible. It is conceivable that an end pin formed as a gear and the opposite recess is formed as an external gear with interposed planetary gear. In this way, adjacent rotor core segments can be operated at different rotational speeds, which are, however, in a constant relationship to each other. This is advantageous because at different heights different wind forces and wind speeds prevail. Thus, it is advantageous to operate a higher rotor core segment at a higher speed than a lower rotor core segment. Furthermore, it is conceivable that adjacent rotor core segments are stored at different locations in the floor panels. More preferably, these have an intermediate gear that causes a constant speed ratio of the adjacent rotor core segments.

Furthermore, the segmentation of the rotor proves advantageous in the assembly. Thus, the individual rotor core segments are initially transported separately from each other and are assembled only on site to a preferred multi-part overall wave of the rotor. Depending on the design of the wind turbine, the number of rotor core segments may preferably be selected between one and twenty. If only one rotor core segment is provided, then only a one-piece drive shaft is provided. If, for example, eight rotor core segments are provided, they also form, in the assembled state, a single drive shaft, which, however, consists of eight individual shafts connected to one another. In particular, depending on the size of the wind turbine, the rotor core segments may be solid and / or at least partially hollow. The latter proves to be advantageous due to the reduced weight, especially in production, transport, installation and storage.

In a further advantageous embodiment, each rotor core segment is bounded on the end by at least one rotor disk and comprises at least one rotor blade. The rotor discs are advantageously used for additional stabilization of the entire rotor. In addition, at least one rotor blade, preferably two, more preferably two to ten, most preferably three to five, rotor blades are arranged between two rotor disks arranged adjacent to one another. The fixation of the rotor blades is preferably such that no removal of the rotor blades is possible during operation. However, the present invention provides that the rotor blades in the case of maintenance or repair of the rotor discs are removable and individually designed interchangeable. If only one rotor core segment is provided, then the rotor contains two rotor disks, between which at least two, preferably three to five, rotor blades are fastened. The rotor blades in this case preferably have a continuous spiral shape.

It is conceivable that the rotor disks have the shape of a full disk surface. However, they preferably have material omissions. In this case, an outer ring with inner struts is advantageous. In this way, a stabilization of the rotor blades is achieved while saving material. Advantageously, such rotor discs consist of a core ring, at least three, preferably six, struts and an outer ring.

It is further conceivable that the rotor blades are formed as lamellas and / or aerodynamic wing profiles. Depending on the number of rotor blades provided, these are correspondingly offset from one another in order to ensure a correspondingly high energy yield. For example, if three rotor blades in use, they are advantageously arranged offset to one another by 120 °. Aerodynamic wing profiles are preferably to be understood as meaning those shapes which have a wing-like outline, wherein preferably both wing front and rear side are at least partially convexly curved and / or at least wing front side and / or wing rear side is convexly curved. Wing front side is preferably to be understood as meaning the wing surface on which the air flow impinges. In addition to the shapes described here, it is also conceivable to form the rotor blades flat, that is to say without curvature, and / or with an ellipsoidal cross section.

If the rotor blades are designed as lamellae, they are not flat, but comprise at least one bend in their longitudinal extent, so that a U-shaped cross-section is formed. This is advantageous because thus the impinging air flow has a larger attack surface and thus the rotors are set into rotation faster. In addition to the shapes described here, moreover, the rotor blades can also be bent several times, for example in a waveform. In the simplest case, the rotor blades are made of metal. However, this is not limiting, as it has been found advantageous to provide the rotor blades as a hollow profile, for example with a preferably airtight textile and / or plastic covering. As a result, the weight of the rotor blades is advantageously additionally reduced.

The rotor blades are advantageously formed on the rotor discs inclined in the direction of the axis of rotation of the respective rotor. This is advantageous for wind energy absorption. Preferably, the rotor blades with respect to the rotor disk by 0 to 20 °, more preferably formed by 0.1 to 10 ° inclined. Furthermore, it is advantageous to arrange the rotor blades near the edge of the rotor disks, since in this way the best possible power conversion is realized. In this case, it is preferable to understand near the edge that the rotor blades are flush with the circumference of the rotor disk and / or are set back radially inward by 0.5 to 50 cm from this.

Moreover, it has proven to be advantageous, in particular in rotor discs with a diameter of greater than 3 m, the rotor blades also arranged in groups. This is advantageous, since thus a complex and cost-intensive production of large-area rotor blades is avoided.

In a further advantageous embodiment, each rotor core segment comprises at least one group of rotor blades, preferably three to five groups of rotor blades. Advantageous are groups from 2 to 8, more preferably from 3 to 5, rotor blades provided. Further preferably, the rotor blades within the groups are arranged offset from one another to produce the largest possible air impact surface. As already described above for the individual rotor blades, furthermore preferably 2 to 7 of the rotor blade groups are arranged between two rotor disks arranged adjacent to one another, the spacing of which being dependent on the number of groups. For example, two groups are arranged 180 ° opposite to each other, whereas three groups are arranged at an angle of 120 ° or four groups at an angle of 90 ° to each other.

In a further advantageous embodiment, the rotor blades are arranged offset to one another in the longitudinal extent of the rotor, wherein the rotor blades of two mutually adjacent rotor disks are preferably formed by 2-90 ° and more preferably by 10-60 ° offset from each other. This is advantageous since, as a function of the height of the wind turbine, a significant impact reduction can thus be achieved. In addition, the known in vertical systems disadvantage of a "pulsating torque" is prevented, so that a quiet and stable run, even with very large systems is ensured. By this offset to each other, the shape of a spiral is conditional, so that the air flow causes a uniform drive of the rotors and a wing flap is prevented. Furthermore, this arrangement, offset relative to one another, causes the air flow flowing past the rotor blades to be accelerated again, thus providing additional energy. Preferably, the displacement of the rotor blades to each other depending on the height of the wind turbine used. If, for example, the rotor comprises eight rotor core segments or nine rotor disks, it has proven to be advantageous to arrange the individual rotor blades per rotor disk by 15 ° offset from the previous rotor disk. The rotor blades preferably form a spiral shape from top to bottom, so that wing flapping is prevented and the rotor barrel is stabilized against vibrations.

In a further advantageous embodiment, the radial extent of the rotors is reduced in their longitudinal extent in the direction of the upper rotor carrier element. This conical shape is advantageous because it avoids vibrations caused by different airflow velocities at different heights.

In a further advantageous embodiment, the wind power plant further comprises air guide surfaces which are designed such that they at least partially shield rotor blades which are running inside, preferably with a rotation of the rotors against an air flow, in order to enhance a rotation of the rotors and an inflow air flow (W) from the center deflect outwards onto the outer rotor blades. This is advantageous because in this way an increased rotation of the rotors is effected and the vertical principle is only interesting. Furthermore, it is conceivable that the air guide surfaces deflect, compress and divide an inflow air flow from the center to the outside. In addition, the air guide surfaces are preferably designed such that forms on its inner side, which faces the central support, a negative pressure. As a result of this suction, rotating blades are accelerated from the inside to the outside. Advantageously, the wind turbine comprises air guide surfaces, which are designed such that they direct air flowing perpendicularly to the connecting line of the rotors from the center outwards, so that air flowing against the air guide surfaces is redirected to blades located on the outside of the rotors and causes an opposite rotation of the rotors. Preferably, the air guide to this are placed approximately wedge-shaped. The wedge shape points in the wind direction and divides the wind jet, with a split, compressed wind jet and / or wind current being created on both sides.

It is conceivable that the air guide surfaces, based on the preferably conically upwardly tapered rotors, also have a tapered shape at the top, so that the surface, which impinges on the inflow air flow decreases upward to the free end of the central carrier out. This taper is preferably in the same ratio as the conically seated rotors. As stated, the rotors are moved by the air flow of the windward side. Advantageously, the flow is additionally reinforced by the compressed air mounted in front of the central support Luftströmungsleitflächen. Preferably, the air guide surfaces are further designed such that the rotating with a rotation against the wind direction rotor parts, in particular the rotor blades, in part, preferably completely, are shielded from the inflow air flow.

It is also conceivable that the air ducts are used for advertising, advertising, company logos or other. This is advantageous in areas close to the city. In another embodiment, the air guide surfaces have a neutral color composition. This is beneficial for natural and cultural landscapes. In addition, it is conceivable to provide the air ducts with solar collectors for additional energy. This is particularly advantageous at low wind.

Furthermore, it is conceivable that the air guide surfaces additionally have extension elements. In this way, the proportion of the on the Reduce or increase the rotor blades of the incident flow. Furthermore, the air guide surfaces are preferably designed pivotable about a substantially vertical axis. In a particularly preferred embodiment, the air guide surfaces are multi-part, preferably formed in two parts, so that if necessary, for example, for maintenance, the surface of the air guide can be increased in order to put the system at rest. With fully extended air ducts, the deflection of the incoming air flow is such that the rotors remain at rest and no drive takes place. Maintenance can thus be carried out safely. Depending on the embodiment, the air guide surfaces are preferably formed convex and / or concave curved. Both curves have proven to be advantageous to direct the air flow targeted at the rotors.

Particularly advantageously, the air guide surfaces are formed symmetrically with respect to the pivot axis. This is particularly advantageous in the extended state, since then the air guide preferably extend up to the height of the axes of rotation of the rotors and thus allow shielding of the incoming air. The control of the air guide surfaces is also symmetrical in the simplest case, but not limited thereto. Thus, it is also conceivable that during maintenance of only one rotor, this is shielded by unilaterally extended air ducts, while the other rotor fully functional energy produced and the air ducts are arranged on the side in the non-extended state.

In addition, it is conceivable to provide at least one brake system for the rotors. Each rotor preferably has a corresponding electrical and / or mechanical brake system. Braking systems are particularly beneficial in maintenance to slow down and / or stop the rotors. In addition, the at least one brake system is also advantageous, since the wind turbine can thus be brought to a standstill even with unausgefahrenen Luftleitflächen.

Preferably, the brake systems include an energy conversion system, by means of which the braking energy is temporarily stored and reused for renewed startup for faster acceleration of the rotors. Advantageously, the at least one brake system serves to support the already described air guide surfaces.

Both air ducts and / or brake system prove to be particularly advantageous for maintenance and repair work, full power without feed-in possibility and / or strong gale-force winds, which can be operated by the advantageous construction of the wind turbine described here even in stronger winds than previously known systems from the prior art.

Particularly preferably, a radial expansion of individual components of the rotors decreases upward in the direction of the free end of the central carrier.

The result is a total upwardly tapering shape of the plant. Due to this design, the entire center of gravity of the system shifts far down. In contrast to the conventional, modern horizontal wind turbines, the wind pressure load in a storm or hurricane not only affects the top of the central girder, but evenly distributed over the entire central girder. The center of the pressure load is advantageously below the central carrier center of gravity. This increases stability, saves material and reduces vibration. This achieves high stability and insensitivity in storm and hurricane. The noise emission is comparatively low.

This design is advantageous for a better use of space and yield. The plants can be built much closer to each other without disturbing each other, as it is known from horizontal wind turbines. In addition, they can be built smaller and lighter in height compared to other systems in their performance class. The terms are longer than comparable systems or HAWT. The design requires a smaller design and a lighter mass for comparable performance class. This leads to a higher efficiency compared to horizontal wind turbines. It allows an improved landscape and the bird airlines are less affected.

It is also conceivable that the rotors are connected directly to generators for direct power reduction. These are designed for comparatively low speeds. This saves the use of gears, belts and other mechanisms and thus increases the economic use of the system. In an advantageous embodiment, based on this principle, a system is equipped with two generators, which are each attached to the lower end of each rotor. This is especially advantageous for smaller and medium sized systems. The power of the generators is preferably fed together or individually into the network. Furthermore, it is also conceivable to provide a transmission for acceptance, wherein the above-described transmission-free power reduction is preferred. In addition, a coupling of the rotors used is also conceivable.

Further advantageously, the power reduction takes place directly from one or more Rotor discs and / or rotor carrier element. This is preferably achieved by arranging at least one permanent magnet on the outer circumference of one or more rotor discs and / or rotor carrier elements. Advantageously, at least one winding or at least one coil is attached to the associated plate-like frame element or the associated rotor carrier element. The permanent magnet is exemplified by neodymium. Known ring generators of horizontal systems find use in a particularly preferred embodiment. Since the generator would thus be integrated into the wind turbine, the entire system could also be regarded or referred to as a wind power generator. The use of such ring generators advantageous wear parts are reduced. Of course, the decrease in power is not limited to the mentioned embodiments. Furthermore, the use of asynchronous generators is conceivable.

Since vertical axis wind energy converters are known for their smooth running and offer a less disturbing sight like HAWT systems, they are advantageously deployed in localities, cities and industrial areas and connected to the local power supply. This saves many kilometers of power lines.

Likewise, the electricity can be fed into communities or towns in the public network or stored in batteries and used to recharge e-cars, e-bikes and street lighting.

The object is also achieved by a method for the use of wind energy by means of a wind turbine according to one of the described embodiments, wherein the inflow air flow is shielded by air guide of running with a rotation against a Anströmluftfluss rotor blades and directed to the rotor blades of each other inclined rotors. For the geometric design of the air guide or the angle of inclination of the rotors to each other and / or the angle of inclination of the rotors to the central support is made to the above-described embodiments and these are completely included for the process. In particular, the guiding of the air on mutually inclined rotors is particularly advantageous because it takes into account a dependence of the wind speed of the amount.

In a further advantageous embodiment, plate-like frame elements and / or guide elements arranged thereon center, stabilize and guide plate-like frame elements and / or guide elements arranged thereon on the rotor frame in the rotor frame. This is advantageous since vibrations and material stress on the rotors can be minimized with little effort.

The object is also achieved by a method for producing a wind turbine. A first step is the erection of a substantially vertical central support. This is followed by the hanging arrangement of a rotor frame frame for receiving rotors on the central support. Here, a first step is the rotatable placing of an upper rotor carrier element for receiving rotors on the central carrier and a second step arranging a lower rotor carrier element parallel to the upper rotor carrier between a base and the upper rotor carrier element, wherein the lower rotor carrier element is guided on the central carrier.

In particular, the first step with a central carrier and the subsequent arrangement of a rotor frame frame is advantageous, since in this way very time and cost efficient, a very effective wind turbine can be provided.

Furthermore, it is advantageous that the rotor carrier elements are also made of metal, preferably steel or aluminum. Embodiments of aluminum or steel are also conceivable for rotors and / or rotor segments and / or rotor disks and / or rotor blades and / or rotor core segments and / or end pins. Thus, there are advantageously no hazards during the processing of epoxy resins, since the rotors are not made of plastic. However, composite materials are also conceivable, for example fiber-reinforced carbon composite.

It is also conceivable that the rotor discs in diameter are slightly larger than the rotor blades attached thereto. Thus, they serve advantageously the leadership and stabilization of the rotor in the rotor frame frame and the concentration of air flow to the wings. Dodge of the air flow up or down is prevented.

In addition, the rotor support plates and / or floor panels and the rotor discs are designed such that they are at least partially accessible. In the maintenance state, personnel can reach the respective rotor carrier plate and / or floor plate via the central carrier and from there to the respective rotor disk, where they perform maintenance work accordingly.

It is also conceivable that such wind turbines are used on ships or boats. The energy gained is preferably used for the general power supply of the ship. It can also be used as a drive become. For this purpose, it is advantageous to form the central carrier as a mast. A balance of ship fluctuations is then ensured for example by motors or ropes.

Further application possibilities arise on private properties with their own home, on community areas or in wind farms. The wind turbines can be used in cities for general energy supply, to supply charging stations for electric bicycles and electric cars and for street lighting. On islands, they can be used advantageously for general power supply.

At sea offshore wind farms are conceivable, preferably designed as floating platforms, for example in the triangle as a mobile power plant group. For such offshore wind farms, the wind turbines described here can be arranged in a much higher density, resulting in advantageously shortened cable and connection paths. Advantageously, the floating platforms as individual modules, for example, as a hexagonal formed floating body, be formed and be arranged in any number honeycomb to each other. Very particularly advantageous, these individual modules each comprise at least one described wind power plant, which is preferably fixedly arranged on the at least one floating body. Advantageously, the connection of the individual modules is done manually and / or via remote access. For this purpose, each individual module furthermore preferably comprises at least one drive element, for example a motor, and / or a control module, so that the respective module and / or a plurality of mutually arranged modules which form a platform can be controlled and positioned by remote access. This is particularly advantageous for changing wind conditions or for maintenance purposes.

Another possibility is an application in crisis areas and other emergencies. Furthermore, the wind turbines described here can be used on ships as environmentally friendly propulsion and / or power supply at sea, so that can be dispensed with heavy oil.

Furthermore, it is conceivable to provide more than two rotors, for example three, four, five or even six rotors.

Depending on the embodiment, the size of the wind turbine described here is preferably in the range of 20 cm to 150 m, more preferably in the range of 10 m to 100 m. The rotor blades comprise an extension between two rotor disks of preferably 1 m to 15 m, more preferably from 2 m to 12 m and most preferably 10 m.

13 Connection of two rotor core segments via a planetary gear

14 Top view of a schematic planetary gear

1 shows a perspective view of a wind turbine 1 in the energy-generating state. In this embodiment, the conically tapered central support comprises 2 , a rotor frame 10 with an upper one 11a and a lower rotor carrier plate 11b and three further plate-like frame elements arranged parallel thereto 12 , preferably floor panels, each with rod-like frame elements 13 with the respective rotor carrier plate above / below it 11a . 11b or the underlying plate-like frame elements 12 are connected. The upper rotor carrier plate 11a is by means of bearings 14 rotatable about the axis of rotation D3 on the central support 2 arranged and / or hung on this. The wind turbine 1 has two rotors 8th . 9 on, which are tapered upwards. The two rotors 8th . 9 or their axes of rotation D1 and D2 include an imaginary angle, which is preferably between 1 ° and 20 °. The rotors 8th . 9 are rotatable about their respective axis of rotation D1, D2 mounted on both rotor support elements 11a , b attached. The two rotors 8th . 9 are designed such that, in Luftströmungsbeaufschlagung, are rotatable in opposite directions to each other.

In each space between two plate-like frame elements 12 or the rotor carrier element 11a . 11b every rotor has 8th . 9 by way of example at least one rotor core segment 21 , which may be formed as a continuous, one-piece shaft and / or a plurality of composite shaft segments. In the embodiment shown here form a plurality of rotor core segments 21 the rotors 8th . 9 out. At the ends of the rotor core segments 21 are rotor disks 23 arranged. Two rotor discs 23 are through the interposed rotor blades 24 spaced apart. The rotor blades 24 are formed lammellenartig in this embodiment and have a curved and / or U-shaped cross-section. The rotor blades are preferred 24 in the direction of the core core segment 21 inclined, preferably at an angle of 0.1 to 10 °. The exemplary lamella is preferred 24 formed with a constant cross section, wherein it is also conceivable that it tapers at least towards one end and / or has a greater curvature.

Furthermore, the wind turbine includes 1 a pedestal 3 on which the central carrier 2 is arranged. A pedestal can be any Bodenbestigung, for example, a foundation, a stand or the like. rotors 8th . 9 as well as rotor frame frame 10 are in the simplest case at the same time rotatable movable. However, it is also possible rotors 8th . 9 or rack 10 together and / or individually to block, for example, in case of maintenance In addition, here are the air ducts 40 in the retracted state, ie in the state of energy production shown. The air ducts 40 are formed convexly curved and share the impinging air flow, shield the rotor blades running counter to the wind direction in front of him and thus lead this reinforced directly to the outer rotor blades of the opposing rotors 8th . 9 , Advantageously, the air ducts 40 pivotable in their position and / or formed changeable in their surface. In addition, on the airflow side facing away from the air guide 40 generates a negative pressure, which exerts a suction effect on the outgoing rotor blades. Ends the air ducts 40 breaks off the shielding of the air flow W and the suction effect begins. As a result, the air flow W in the direction of the rotors 8th . 9 guided and also preferably accelerated at the same time. Thus, a targeted guided, accelerated air flow W hits the rotor blades 24 and causes the rotation of the rotors 8th . 9 , This will be in 1 illustrated.

2 shows the wind turbine 1 in the maintenance state, ie in the stationary state, wherein the same reference numerals as explained above are not redefined. In this state, the rotors are 8th . 9 quiet. The air ducts 40 are extended and form a shield. The on the extended air ducts 40 impinging air flow is through the air ducts 40 guided so that he was on the rotors 8th . 9 passes without rotating them about their axes of rotation D1, D2. This is particularly advantageous in the case of maintenance, since the service personnel thus safely the rotors 8th . 9 can wait and repair.

The central carrier 2 is in 3 shown again in a perspective image for better understanding. At the upper free end of the central carrier 2 is the camp 14 arranged. At this camp 14 the attachment and / or storage of the rotor support element takes place 11a (not shown) and thus also the suspension of the frame 10 ,

In 4 is a rotor frame 10 shown for a better understanding. The rotor frame frame 10 is from the upper and lower rotor carrier plate 11a . 11b limited. The rotor carrier plates 11a . 11b have a pointing in the air flow direction W wedge shape, which diverge slightly curved towards the air flow direction W outwards and terminates with a straight edge on the side facing away from the wind. The geometry of the rotor carrier plates is preferred 11a , b formed such that at least one, preferably two of its side surfaces are curved outwardly. This is advantageous for the targeted guidance of the incoming air flow W.

The rotor carrier plates 11a , b preferably further comprise two openings 29a , b for receiving and supporting the respective rotors 8th . 9 (in 4 not shown) and at least one further opening 30 in the lower rotor carrier plate 11b for guiding the rotor frame frame 10 at the central carrier 2 (in 4 Not shown). Furthermore, the rotor carrier plates include 11a , b and the other plate-like frame elements 12 in the outer edge region preferably three more openings 28 for receiving and arranging the rod-like frame elements 13 , In this example, the rotor carrier plate comprises 11a Furthermore, preferably on its axis of symmetry S the storage point and / or the bearing surface L, at which the suspension and / or mounting of the upper rotor support plate 11a at the central carrier 2 (in 4 not shown). It is clear that in this embodiment the bearing surface L is not centered in the upper rotor support plate 11a is arranged, but is formed offset from the central center. This is advantageous because thus the two rotors 8th . 9 in Air flow direction W behind the central carrier 2 are arranged.

The plate-like frame elements 12 , designed here as a floor panels, correspond in their circumferential geometry the rotor carrier plates 11a , b. In addition, the frame element comprises 12 two enlarged openings 26 in which the rotors 8th . 9 are feasible. In addition, the frame element includes 12 and the lower rotor support member 11b still an additional opening 30 , through which the frame around the central support, not shown 2 is feasible. In the outer areas of the plate-like frame elements 12 are still several openings 28 for receiving and fixing the rod-shaped frame elements 13 intended.

Furthermore, the openings comprise 26 . 30 preferably at least three, preferably six, guide elements 34 , The guide elements are preferred 34 evenly spaced at the edge portions of the openings 26 . 30 arranged so that it at least partially into the opening 26 . 30 protrude and reduce their diameter. Further preferred are the guide elements 34 preferably formed elastically, so that they central carrier 2 and / or rotors 8th . 9 when force application and a stop at the edge regions of the openings 26 . 30 prevent. The shape of the guide elements 34 can be designed variable. Further preferred are the guide elements 34 itself formed rotatable. This is advantageous for rapid power dissipation during application of force.

The guide elements 34 serve the leadership of rotor 8th . 9 in the rotor frame 10 as well as the rotor frame frame 10 at the central carrier 2 and act as noise reduction and vibration reduction.

In 5 is an exemplary rotor 8th with lamellar rotor blades 24 shown. The rotor 8th includes here by way of example eight rotor core segments 21 The rotor discs 23 separate the individual rotor core segments 22 , In an external position has a rotor blade 24 with the vault exactly against the wind direction. Between the rotor blades 24 and the rotor core segment 21 is an air gap. This has the advantage that moving against the wind direction rotor blades 24 on the inside does not lead to a back pressure jam, because the air gap allows easy pressure equalization. Furthermore, the lamellar shape or wing shape has the advantage that the strongest possible movement is generated by the wind power on the outside, on the inside, however, the lowest possible wind resistance prevails.

Depending on the design, as already mentioned above, the rotor 8th . 9 be formed in one piece or multiple parts. So is also conceivable, the rotor 8th . 9 form two parts, so that two interconnected rotor core segments 21 are provided. This training is of course not limited to the embodiment described here, but applicable to all above already executed variants of the wind turbine.

At the upper free end 36 of the rotor 8th or 9 can be another camp 38 be provided, which is the rotation of the rotor 8th . 9 around the corresponding axis of rotation D1, D2 allows. In addition to training as a camp training as a guide pin is conceivable, which then in a camp (not shown) of the rotor carrier plates 11a , b intervenes.

6 shows a further schematic view of a wind turbine 1 but without air ducts 40 , The same reference numerals as in the preceding figures will not be explained again. The rotors 8th . 9 are in the air flow direction behind the central support 2 arranged.

In 7 is another plan view of a wind turbine 1 shown in the energy-gaining state. In 7 are the air ducts 40 shown in the retracted, undeflected state, so that preferably the maximum possible air flow strikes the rotor blades movable in the direction of air flow and at the same time the rotor blades running against the inflow air flow are shielded from the air flow. However, this is not limiting, since the air guide 40 are pivotable about the axis A, so that they are deflected from their rest position. This can be controlled manually or automatically by means of sensors. Preferably, the pivoting of the air guide surfaces takes place 40 depending on the wind speed. The illustrated position of the air ducts 40 is preferably chosen at a lower wind, by the refraction of the incoming air flow this before impinging on the rotor blades 24 to accelerate again. Thus, the effectiveness of the wind turbine described here increases 1 clear. In dashed lines are further air guide elements 42 shown perpendicular to the air flow direction laterally outside. These serve to compress air and increase the amount of air impinging on the rotor blades. It is conceivable that these other air guide elements 42 as a spacing frame elements 13 (not shown here) are formed.

8th shows a further schematic plan view of a wind turbine 1 in the maintenance state, ie with extended air ducts 40 , When extended, the air deflectors shield 40 the rotors 8th . 9 essentially completely from the inflowing air flow, so that maintenance and repair work is safely possible. The air guide surfaces are therefore preferred 40 multi-part, at least two parts, trained. The extension of the air ducts is done by machine, for example by means of motors (not shown) and can be done manually on site or automatically via remote maintenance.

In 9 is a plan view of the arrangement of the rotors 8th . 9 shown, wherein the rotor frame frame is not shown. The same components as described above have the same reference numerals and will not be explained again. Here is to be shown that the individual rotor blades 24 of the respective rotor 8th . 9 offset from each other can be arranged to ensure a correspondingly large power loss. In this embodiment, a total of eight segments 21 shown. On each rotor disc 23 are each three rotor blades 24 arranged at a distance of 120 °. Always two adjacent to each other arranged segments 21 point in the spaces between the adjacent rotor discs 23 to one another by the angle α of 60 ° staggered arrangement of the rotor blades 24 on. However, this is not limiting. Thus, it has surprisingly been found that a stepwise displacement of the rotor blades from top to bottom in a range of preferably 15 ° to 30 ° to each other represents a particularly effective training. Due to the consequent spiral shape of the rotor blades 24 an effective possibility of exploiting the wind power is ensured. The transfer is also always based on the height of the entire system, so is for eight segments 21 a displacement of 15 ° advantageous, whereas at 6, 5, or 4 segments 21 an offset of 20 °, 24 ° and 30 ° is advantageous.

The 10 to 12 show possible uses of the wind turbine described here, for example, in the off-shore area on a floating, honeycomb-like support structure or as a mast on a ship.

13 and 14 show a connection between two rotor core segments 51 . 52 via a planetary gear 53 , The upper rotor core segment 51 has an end pin 54 with a gear 58 on. This endpin 54 is located in a recess of a second rotor core segment 52 with external gear 56 , In between are so-called planetary gears 60 arranged to achieve a constant rotational speed ratio.
