Description

The invention relates to a wind or hydropower plant with the features of the preamble of claim 1 and a method for generating energy with the features of the preamble of claim 19.

Wind turbines for generating electricity are already well-known. The most common horizontal type has three rotor blades arranged on a horizontal axis at a height of up to 160 meters, driving a generator. The rotor blades are up to 120 meters long, with the outer section rotating rapidly around the axis, causing drag turbulence and constant noise. The energy input of the wind turbine is controlled by adjusting the angle of the rotor blades to the wind, with the wind hitting the blades parallel to the generator axis for optimal efficiency. Furthermore, the tower on which such a wind turbine is installed also presents a challenge, as the airflow is slowed down immediately in front of the tower, resulting in significant variations in pressure on the rotor blades in this area.

Vertical axis wind turbines with a so-called Savonius rotor are also known. These wind turbines have two or more blade-shaped, overlapping blades that are stretched along the axis of rotation and mounted between a base and a cover. In these types of wind turbines, the rotating elements are also freely accessible to convert the wind flow into electrical energy.

Due to their freely accessible moving parts, conventional wind turbines can only be installed in appropriately secured environments. Furthermore, conventional wind turbines also exhibit a certain degree of noise generation from the wind flowing around the rotor blades or the Savonius rotor, which is a disadvantage.

Hydropower plants utilize Kaplan, Francis, or Pelton turbines to generate energy from water. In Kaplan turbines, the water flows parallel to the turbine's axis of rotation. Francis and Pelton turbines, on the other hand, direct the water tangentially onto the turbine blades to drive them. Water screws are also known, in which water introduced at the screw's upper inlet and gravity set the turbine in motion.

A device that can be used for electricity generation both as a wind turbine and as a hydroelectric power plant is not known.

The object of the present invention is to create a wind or hydropower plant which is structurally simple, has a large receiving area with a small turbine diameter, offers increased safety compared to known plants, and solves the aforementioned problems.

This problem is solved according to the invention by a wind or water power plant with the features of claim 1.

According to the invention, a wind or water power plant is provided, comprising a housing, a turbine and a generator driven by the turbine, wherein the housing has an inlet opening for the wind or water to flow into the turbine and an outlet opening for the wind or water to flow out of the turbine.

The essential feature is that the casing has a flow-guiding casing part designed as a wind or water intake surface to compress the air and increase the wind or water speed used to drive the turbine, and that the turbine is arranged completely inside the casing, and that the turbine is designed as a worm shaft.

The flow-guiding housing component offers the advantage of an enlarged wind or water intake surface that extends beyond the turbine's dimensions, thus enabling higher energy generation. Furthermore, this wind or water intake surface is not a rotating component, thereby increasing the system's safety and eliminating noise generation.

The advantage of completely enclosing the turbine within the casing is a safer and quieter wind or hydropower plant. The rotating components are shielded from the environment by the casing. Furthermore, the turbine's complete enclosure provides greater stability, making the wind or hydropower plant less prone to malfunctions and requiring less maintenance, and allowing for the use of higher wind or water speeds for energy generation.

Furthermore, the design of the turbine as a screw shaft results in a high efficiency. efficiency in energy generation. Furthermore, the use of the worm shaft is advantageous because higher wind speeds and pressures can be used to drive the turbine, as its design makes it more stable than conventional rotor blades and—as previously described—it features bearings on both sides. The design of the housing section also offers the advantage of introducing the flow in the form of a hyperbolic spiral immediately before it impacts the turbine. This concentrates the accelerated and/or compressed flow onto the outer surfaces of the worm shaft, resulting in concentrated jet spraying. This leads to significantly higher torque. The combination of the flow-guiding housing section with the use of the turbine as a worm shaft is particularly advantageous, as it allows the energy of the accelerated and compressed air to be converted into electrical energy with high efficiency by the stable turbine.

It can be provided that the flow-guiding housing section has a concave surface in a first region, starting from a housing tip. In this region, the flow is captured largely tangentially. Preferably, the flow-guiding housing section has a convex surface in a second region, which connects to the concave surface with a continuous curvature transition. It can also be provided that the convex surface transitions into the inlet opening with a continuous or at least tangential curvature transition. Advantageously, this special form of wind guidance in both regions results in efficient wind or water collection, thereby increasing the wind or water volume and flow velocity, while simultaneously reducing turbulence and disturbance in the inlet opening area caused by the concave surface and the continuous curvature transitions. This allows the entire front housing surface to be used as a wind-capturing surface for driving the turbine.

It can be provided that the flow-guiding housing part is designed to face against the direction of wind or water flow, particularly towards windward. "Against the direction" preferably means that the flow-guiding housing part is located in the front region of the housing, i.e., in the area that first comes into contact with the wind or water. This allows the flow-guiding housing part to be used to increase the wind or water volume and flow velocity used to drive the turbine.

It can be provided that a second flow-guiding housing section is designed with the direction of wind or water flow, particularly pointing downwind. "Direction" here preferably means that the flow-guiding housing section is located in the rear area of the housing, i.e., in the area that comes into contact with the wind or water last. This reduces turbulence caused by the wind or water flowing around the housing. This is particularly advantageous when the inlet opening is closed, for example, during maintenance of the system, as this results in very little turbulence from the system.

The housing can be designed symmetrically, preferably with mirror symmetry in the horizontal and/or vertical direction. Preferably, with mirror symmetry in the horizontal direction, this means that two flow-guiding housing parts are symmetrical to each other and one above the other in the front region of the housing. With mirror symmetry in the vertical direction, this means that two flow-guiding housing parts are symmetrical to each other and adjacent to each other in the front region of the housing. Advantageously, the symmetrical design of the housing results in increased energy yield when two turbines in the wind or hydropower plant are also designed symmetrically, as well as improved flow characteristics within the housing.

A wind turbine housing can be designed to be either rotatable or fixed to a tower or a flat surface, such as a building roof. The advantage of a rotatable design is that the wind turbine can be steered to follow the wind direction. The advantage of a fixed mounting is that, under mostly consistent wind conditions, a very stable installation is possible without requiring much space, and larger turbine sizes can be used.

For a hydropower plant, the casing may be designed to be connectable to an inlet and/or outlet. This allows water from a reservoir to be fed directly into the hydropower plant, with the design of the casing's flow-guiding section increasing the water flow velocity. Similarly, an outlet allows the water to be discharged from the hydropower plant.

It can be designed so that the wind or water intake of the turbine is perpendicular or orthogonal to the turbine's axis of rotation. This means, in particular, that the wind or water is fed to the screw shaft laterally, i.e., not as in a water turbine screw, where the intake and discharge of water occur at the respective ends. The advantage of this is that the larger intake area of the turbine allows the wind or water to be used more efficiently to drive the turbine, thus enabling higher energy generation.

It can be designed so that the turbine's wind or water intake is perpendicular or orthogonal to the turbine's axis of rotation along its entire length. This allows all the wind or water, which is compressed and/or accelerated by the flow-guiding casing section, to be used to drive the turbine.

Preferably, the turbine's wind or water intake can be arranged perpendicular or orthogonal to its axis of rotation, but only over a portion of its longitudinal extent. In this arrangement, the wind or water that would otherwise strike the turbine at the outlet opening can be diverted to a section located away from the outlet opening, thus enabling the turbine to drive a longer portion of its length. This increases energy production.

It can be designed so that the wind or water discharge from the turbine occurs parallel to the turbine's axis of rotation. This means that the wind or water is discharged at one end of the screw shaft while rotating. A discharge parallel to the axis of rotation means that the air or water is directed away from the screw shaft in the direction of a hypothetically extended axis of rotation. This ensures high energy yield by directing the wind or water through the entire turbine.

The vertical intake with simultaneous parallel release of the wind or water results in a very efficient conversion of the kinetic energy of the wind or water into electrical energy, since the wind or water is used for energy generation up to the end of the screw shaft, depending on the intake point, and does not flow through the turbine unused.

In particular, the turbine can be arranged vertically or horizontally within the housing. Depending on the turbine's orientation, the inlet opening in the housing and the flow-guiding housing section is designed vertically or horizontally to direct the wind or water directly onto the turbine. "Vertical" and "horizontal" here refer to a horizontal or vertical arrangement within the housing. This allows the turbine to be positioned within the housing according to the requirements of the wind or hydropower plant. For example, a horizontal arrangement is advantageous for a wind turbine on a rooftop, as the turbine can be designed with a lower height but greater width and a long turbine for high energy yield. Conversely, a vertical design is advantageous for a wind turbine on a tower, as it allows for a symmetrical configuration with two turbines arranged side by side.

It is possible to arrange a turbine within the housing. The advantage of this design is that it requires only one flow-conducting housing section and one inlet opening, resulting in a very stable and compact, or optionally larger, wind or hydropower plant.

In a preferred embodiment, two or more turbines may be arranged within the housing. The two turbines may be arranged parallel to each other within the housing. Preferably, the two turbines rotate in opposite directions within the housing. For this purpose, the housing of the wind or hydropower plant may be symmetrically designed. This results in a very stable and low-vibration design for the hydropower plant, especially when the two turbines are arranged in opposite directions within the housing.

The worm shaft can be designed as a shaft with one or more helical turns, preferably with three helical turns. The advantage of three helical turns is that they allow for the simple compensation of manufacturing-related imbalances. The helical turns are arranged spirally around the shaft in the axial direction. The worm shaft can also simply be referred to as a worm with a shaft. The helical turns can also be called a worm helix. "Multiple helical turns" here refers to two, three, four, five, or more helical turns. The multiple helical windings improve efficiency, while simultaneously reducing noise emissions and increasing turbine stability.

It can be provided that the one or more helical turns, preferably the one or more worm helix, have a constant pitch. The pitch can be formed at a constant angle between 10° and 45°. This allows the worm shaft to be manufactured in a simple manner.

It can be provided that the one or more helical turns, preferably the one or more screw helixes, are formed with an increasing angle at the outlet opening, preferably with an increasing angle. An increasing angle means that the distance between two superimposed turns of a screw helix is designed to increase. This results in a larger intake area between the screw helixes in the direction of the outlet. The pitch can be formed at an increasing angle between 10° and 45°. Due to the increasing angle of the screw helix, the additional wind or water intake in the outlet area can also be effectively used to drive the turbine, despite the discharge of the wind or water, which already drives the turbine in the lower section and is transported by the screw helix towards the outlet. This allows for the supply of fresh air or water at any point along the longitudinal extent of the turbine. This allows for the effective use of wind or water along the entire length of the turbine, resulting in increased energy production. Furthermore, it provides the wind or water with an increasing volume of flow that occurs when the wind or water slows down or decelerates towards the outlet.

It can be designed so that the worm shaft has a constant diameter along its length. This makes the worm shaft easier to manufacture.

The screw shaft can be designed with a conical shape, its diameter decreasing towards the outlet. This results in a larger intake area per helix section towards the outlet, allowing for the introduction of fresh air or water at any point along the turbine's length. This means that the additional wind or water intake near the outlet can also be effectively used to drive the turbine, despite the discharge of wind or water, which is already driving the turbine in the lower section and being transported towards the outlet by the screw helix.

In a preferred embodiment, the thickness of the screw helix can increase towards the shaft. This strengthens the screw helix, allowing larger volumes and velocities of air or water to be used to drive the turbine. Simultaneously, this results in a more stable screw shaft, which contributes to reduced noise.

The worm shaft can be rotatably mounted at both ends within the housing. This results in a particularly stable and low-maintenance bearing arrangement. The double-sided support of the turbine shaft within the housing also reduces bearing wear. Furthermore, this type of bearing arrangement allows for the use of larger air or water volumes and velocities, as well as smoother operation.

The housing may be equipped with inlet vanes to adjust the size of the inlet opening. Preferably, these inlet vanes are designed as movable flaps. This allows the injection of wind or water into the turbine to be controlled. The advantage of this design is that the position or orientation of the rotating element, i.e., the turbine, is not changed under varying wind or water conditions; instead, the energy generation of the wind or hydropower plant is controlled via the inlet vanes. This enables the operation of the wind turbine even at high wind speeds or during storms, as the inlet vanes can be controlled to remain open only a small gap. Complete closure of the inlet opening, for example for maintenance work, is also possible.

The inlet vanes can be designed with a concave inner surface, preferably with a continuous curvature transitioning into the inlet opening. The concave design can create a continuous reduction in the size of the inlet opening to further accelerate the wind or water. The concave design allows additional wind or water, beyond that collected by the flow-guiding housing section, to be accelerated towards the inlet opening. This special shape of the inlet vanes advantageously results in the efficient collection of wind or water, increasing both the wind or water volume and flow velocity, while simultaneously minimizing turbulence at the inlet opening thanks to the continuous curvature transition. This allows for a further increase in the wind or water intake area and velocity.

The inlet vanes can be designed to be controllable via one or more motors, preferably servo motors. This allows for control of the wind or hydropower plant that can be adapted to the respective environmental conditions or for maintenance work. The position of the inlet vanes can be controlled by the system or automatically adjusted depending on the environmental conditions.

The outlet opening may be designed to have a wind- or water-carrying outlet, which redirects the wind or water from the direction parallel to the turbine axis back into the original wind or water direction. The original wind or water direction is understood to be the direction in which the wind or water strikes the flow-conducting casing part.

The wind- or water-carrying outlet can be designed in the form of a screw with a continuously rotating guide and continuous enlargement. Alternatively, the wind- or water-carrying outlet can be designed in the form of a garden snail shell. This advantageously results in a deceleration and a release of the seal from the water or wind exiting the turbine, while simultaneously diverting the flow.

In particular, a void can be provided between the spiral-shaped outlet and the turbine. This distance or void can prevent whipping noises.

It may be provided that the wind or hydropower plant or the housing has a size between 0.2 meters and up to 20 meters, in particular an edge length between 0.2 meters and up to 20 meters.

The wind or water power plant according to the invention is advantageous in that, due to the arrangement of the turbine within the housing, it generates minimal vibrations and is very stable. It is also advantageous that the flow-guiding housing component allows for smaller designs while simultaneously achieving good energy yield, as the wind or water is collected and accelerated by the housing. These smaller versions can, for example, be effectively used for energy generation on a housing roof.

The housing can be made of metal, such as steel or aluminum, plastic, or fiberglass-reinforced material. The material can be adapted to the size of the system.

The wind or hydropower plant may be equipped with a generator, preferably one generator per turbine. The generator may be located on the outside of the housing, or the housing may have a designated space for the generator. Preferably, the generator is directly connected to the turbine shaft.

Furthermore, the problem is solved according to the invention by a method for generating energy with a wind or hydropower plant having the features of claim 19.

• i) Sammeln und Beschleunigen des Windes oder des Wassers durch einen strömungsleitenden Gehäuseteil der Wind- oder Wasserkraftanlage;
• ii) Antrieb einer Schneckenwelle durch Zuführen des Windes oder des Wassers senkrecht zur Drehachse der Schneckenwelle;
• iii) Abführen des Windes oder des Wassers aus der Schneckenwelle heraus parallel zur Drehachse der Schneckenwelle;
• iv) Umleiten des Windes oder des Wassers nach der Schneckenwelle in eine senkrecht zur Drehachse der Schneckenwelle gerichteten Richtung;

According to the invention, a method for generating energy with a wind or hydropower plant is proposed comprising the following steps:

• i) Collecting and accelerating the wind or water through a flow-conducting casing part of the wind or hydropower plant;
• ii) Driving a worm shaft by supplying wind or water perpendicular to the axis of rotation of the worm shaft;
• iii) Discharge of wind or water from the screw shaft parallel to the axis of rotation of the screw shaft;
• iv) Redirecting the wind or water after the screw shaft in a direction perpendicular to the axis of rotation of the screw shaft;

Advantageously, collecting and accelerating the wind through the flow-guiding housing section results in an increased wind or water intake area that extends beyond the turbine's dimensions, thus enabling higher energy generation. Furthermore, the turbine's design as a screw-driven turbine with the drive perpendicular to the screw shaft's axis of rotation results in high energy generation efficiency. The combination of wind collection and acceleration with the feed point perpendicular to the screw shaft's axis of rotation is particularly advantageous, as This allows the energy of the accelerated and compressed air to be converted into electrical energy with high efficiency across the entire surface of the turbine.

The embodiments shown in the figures are exemplary and should not be understood as limiting. Features functioning identically have been designated with the same reference symbols. It is obvious to a person skilled in the art that, within the scope of their technical expertise and the application of the patent claims, they can combine the embodiments shown in the figures without infringing upon the scope of protection afforded by the claims.

The 1 Figure 1 shows an exploded view of an embodiment of a wind turbine 1 according to the invention, with a housing 2 arranged on a tower 3 and comprising two generators 4.

In this embodiment, the housing 2 exhibits vertical mirror symmetry, with the housing 2, as a flow-guiding housing part, having several wind-absorbing surfaces 10, which are designed in the front area of the wind turbine 1 against the wind direction and in the rear area of the wind turbine with the wind direction W. The wind direction W is in 1 This is represented as an arrow. The direction opposite to the arrow means that the flow-guiding part of the housing is located in the front area of the housing, i.e., in the area that first comes into contact with the wind or water, in order to collect wind.

The wind-collecting surfaces 10 in the front and rear regions are designed with a concave surface in the first region, which transitions into a convex surface in the second region with a continuous curvature transition. In the front region, the wind-collecting surface 10 transitions into an inlet opening 12 of the housing 2, which directs the wind into a turbine receptacle 13. Due to the mirror-symmetrical design of the housing 2, two inlet openings 12 and two turbine receptacles 13 are formed.

To collect additional wind and to control the size of the inlet opening 12, two movable inlet vanes 11 are formed on the housing, which in this embodiment have a concave wind receiving surface 10 on the inside, which transition into the inlet opening 12 by means of a continuous curvature transition.

As in 1 As further shown, the wind turbine has two turbines in the form of worm shafts 20, which are arranged completely inside the housing 2 in the turbine receptacles 13 during operation.

For easier understanding of wind turbine 1, in 1 The housing 2 is shown with a cover on which two outlets 14 are arranged for discharging and redirecting the wind from the turbine receptacle 13.

2 The wind turbine according to the invention is shown in the 1 In a schematic representation from a rear oblique angle. Shown is the wind turbine 1 with the housing 2, which is arranged on the tower 3. As in 2 As shown, the worm shafts 20 are arranged completely within the housing 2 during operation. As shown in 2 As shown, the wind hits the housing 2 with the wind-absorbing surfaces 10 from the direction W. The air is compressed and accelerated in the front area of the housing 2 and guided through the inlet vanes 11 into the inlet openings 12. The worm shafts 20 are driven within the housing 2, with the air striking them perpendicular to the axis of rotation 23 of the worm shafts 20. The air is then transferred parallel to the axis of rotation 23 of the worm shaft 20 into the outlet 14 with an outlet opening 15.

3 , 4 until 5 show the wind turbine according to the invention of the 1 and the 2 in a front view ( 3 ), side view ( 4 ) and top view ( 5 Here, identical reference numbers number identical components.

6 and 7 The housing 2 and the inlet wings 11 show the 1 , 2 , 3 , 4 until 5 in detail. This includes... 6 a top view and in 7 A schematic representation is shown. For easier understanding of the figures, the lid of housing 2 has not been shown.

In 6 The top view clearly shows the flow-guiding design of the wind intake surfaces 10. In the front section of the wind turbine 1 (below), the wind, blowing west, strikes the housing 2 with its mirror-symmetrical wind intake surfaces 10. As previously described, the wind intake surfaces 10 each have a concave surface in the first section, which transitions smoothly into a convex surface in the second section. The inlet vanes 11 also have a convex surface on their inner surface. In the front section, the wind is guided by the wind intake surfaces 10 of the housing 2 and the inlet vanes 11 through the inlet openings 12 into the turbine housings 13. The smooth transition and the wind guidance provided by the housing 2 and the inlet vanes 11 collect and accelerate the wind.

The 8 , 9 until 10 show a first embodiment of a turbine according to the invention, which is designed as a screw shaft 20. 8 shows a side view 9 a top view and 10 A schematic representation of the first embodiment of the worm shaft 20. The worm shaft 20 has a shaft 21 and, in this embodiment, three worm helixes 22. The worm helixes 22 are formed as helical windings spirally around the shaft 21 in the axial direction. As in 8 to recognize, in the exemplary embodiment of the 8 , 9 until 10 The worm gear 22 forms an increasing angle. The angle of the worm gear 22 is in the upper region of the worm shaft 20. 8 The spiral is larger than the lower section. As a result, the distance between each spiral helix 22 increases with increasing height.

The 11 , 12 until 13 show a second embodiment of the turbine according to the invention, which is designed as a screw shaft 20. 11 shows a side view 12 a top view and 13 A schematic representation of the second embodiment of the worm shaft 20. According to the worm shaft 20 from the 8 , 9 until 10 The worm shaft 20 also shows 11 , 12 until 13 an upwardly increasing angle of the helical helix 22. In addition to the one in 8 , 9 until 10 The depicted worm shaft 20 points to the worm shaft 22 in the 11 , 12 until 13 an upwardly decreasing conical wave 21. This allows the additional wind intake in the area of the outlet 14 to also be effectively used to drive the turbine, despite the discharge of the wind, which already drives the turbine in the lower area and is transported by the worm gear 22 towards the outlet 14.

The 14 , 15 until 16 show the upper area of the housing 2 with the two outlet openings 14 in a front view ( 14 ), side view ( 15 ) and a top view ( 16 ). As in the 14 , 15 until 16 As shown, the wind, which is emitted parallel to the axis of rotation 23 of the worm shaft 20, is redirected back into the wind direction W through the outlet openings 14 of the housing 2.

In the 17 , 18 until 19 The spiral shape of the outlet opening in the sectional views of the 18 and 19 presented in detail. 17 a side view of the housing 2 with two outlet openings 14, 18 a sectional view along the section plane A - A of the 17 and 19 a sectional view along the section plane B - B of the 17 . In the 18 and 19 The spiral-shaped outlet opening 14 with continuous deflection of the air from the parallel to the perpendicular direction of the axis of rotation 23 of the spiral shaft 20 with simultaneous continuous increase of the volume up to the outlet openings 15 is clearly visible.

The 20 , 21 until 22 Figure 1 shows an inlet nozzle 30 for connection to plant 1 for use in energy generation with water. The inlet nozzle 30 has a flanged section at the inlet, which can be connected to a downpipe for water supply. The inlet nozzle 30 can be used to introduce water into plant 1. The opening is designed to be complementary to the receiving surfaces 10 of the system 1, through which the water is directed into the inlet openings 10 to drive the screw shafts 20. Analogous to the wind turbine 1, the water supply can also be controlled here via the inlet vanes 11, whereby when the inlet vane 11 is closed the water flows laterally around the system 1, or when the inlet vane 11 is open the water is discharged through the screw shaft 20 and out of the outlet openings 15.
