Description
Es ist ein Windkraftrotor offenbart, der einen, um eine vertikale Zentralachse drehbaren, mit mindestens drei Flügelpaaren im Wesentlichen radial angeordneten Rotorblättern, die den Rotor in gleich große Sektoren unterteilen, aufweist. Die Flügelpaare sind in jeweils mehrere Teilblätter unterteilt, welche während der Hintour als Widerstandsläufer oder Auftriebsläufer und während der Rücktour als Auftriebsläufer wirkend ausgebildet sind. Zwischen ihnen sind konvergente vertikale Spalten zum Durchtritt der Luft angeordnet. Durch diese Anordnung wird der Wirkungsgrad eines solchen Windkraftrotors erheblich gesteigert.It is a wind power rotor disclosed, one to a vertical central axis rotatable, with at least three pairs of wings substantially radially arranged rotor blades, the rotor in the same size Divide sectors has. The wing pairs are in each case several part leaves divided, which during the back tour as resistance runner or buoyancy runner and while the return tour as a buoyancy runner are formed acting. Between them are convergent vertical Columns arranged for the passage of air. By this arrangement the efficiency of such a wind turbine is significantly increased.
Beschreibungdescription
Die vorliegende Erfindung betrifft einen Windkraftrotor.The The present invention relates to a wind power rotor.
Windkraftrotoren sind bekannt und sind heute als horizontal rotierende Windräder bereits vielfach im Einsatz. Die horizontal rotierenden Windräder weisen zwar bereits einen beachtlichen Wirkungsgrad, aber auch die bekannten Nachteile, wie z.B. große Bauhöhe, Geräuschentwicklung, Notwendigkeit zur Nachführung, starke mechanische Belastung der Bauteile durch Fliehkräfte und Vibrationen auf. Die mechanischen Belastungen treten insbesondere auch dann auf, wenn das Windrad notwendigerweise in den Wind gedreht werden muss. Außerdem benötigen die bekannten Anlagen entweder eine hohe Anfangswindgeschwindigkeit oder müssen anfangs durch Hilfsmotoren in Rotation versetzt werden.Wind rotors are known and are already today as horizontally rotating wind turbines many times in use. The horizontally rotating wind turbines point Although already a considerable degree of efficiency, but also the well-known Disadvantages, e.g. high height, noise, Need for tracking, strong mechanical stress on the components due to centrifugal forces and Vibrations on. The mechanical loads occur in particular then on, when the windmill necessarily turned into the wind must become. Furthermore need the known systems either a high initial wind speed or have to initially rotated by auxiliary motors in rotation.
Aus diesem Grunde wurden vertikal rotierende Windräder, d. h. Windräder mit vertikaler Achse, konzipiert, die diese Nachteile beseitigen sollen. Der wesentliche Vorteil dieser Vertikalrotoren besteht darin, dass sie keinerlei Windnachrichtungsführung benötigen und die Komponenten leicht zugänglich in Bodennähe angebracht werden können. Aber auch die Vertikalrotoren weisen folgenden prinzipiellen Nachteil auf einer Kreisbahn auf und laufen, wenn der Vertikalrotor auf seiner gesamten Breite vom Wind angeströmt wird, auf der Hintour einmal mit dem Wind und auf der Rücktour gegen den Wind. Dabei rufen die Profile auf der Rücktour durch ihren Strömungswiderstand eine bremsende Wirkung hervor, was den Wirkungsgrad gegenüber dem Horizontalrotor entscheidend verringert. Es wurde versucht, dem Problem dadurch zu begegnen, dass der Rotor in einem Gehäuse eingeschlossen wird, bei dem nur an bestimmten Stellen Luft einströmt (vgl. US 4,350,900). Hierbei ergibt sich jedoch wiederum das Problem, den Wind so zu führen, dass er gezielt in diese Öffnungen eintritt. Hierzu ist dann wieder eine Windnachrichtungsführung erforderlich.Out For this reason vertically rotating wind turbines, i. H. Wind turbines with vertical axis, designed to eliminate these disadvantages. The main advantage of these vertical rotors is that they do not have any wind message guidance need and the components easily accessible near the ground can be attached. But the vertical rotors have the following principal disadvantage on a circular path and run when the vertical rotor on his Whole width flowed in by the wind is against the wind on the way back and on the return trip against the wind. The profiles call on the return trip through their flow resistance a braking effect, what the efficiency over the Horizontal rotor significantly reduced. It was tried, the Problem encountered by the fact that the rotor enclosed in a housing is, in which only flows in certain places air (see. US 4,350,900). However, this again results in the problem to lead the wind like this that he targeted in these openings entry. For this purpose, a Windnachrichtungsführung is then required again.
Ein
anderer Ansatz sieht vor, die Rotorblätter in mehrere Teilblätter zu
unterteilen (vgl. WO 88/09873;
Es ist demzufolge Aufgabe der vorliegenden Erfindung, unter Vermeidung der aus dem Stand der Technik bekannten Nachteilen, einen Windkraftrotor mit einem, um eine vertikale Achse drehbaren Rotor zu schaffen, die einen hohen Wirkungsgrad aufweist sowie leicht und preiswert herstellbar ist.It is therefore an object of the present invention, while avoiding the known from the prior art disadvantages, a wind turbine with a rotatable to a vertical axis rotor, the has a high efficiency and easy and inexpensive to produce is.
Diese Aufgabe wird erfindungsgemäß durch einen Windkraftrotor mit einem um eine vertikale Zentralachse drehbaren Rotor, mit mindestens drei Flügelpaaren im wesentlichen radial angeordneten Rotorblättern, die den Rotor in gleich große Sektoren unterteilen, wobei die Rotorblätter in jeweils mehrere Teilblätter unterteilt sind. Zwischen den Teilblättern sind vertikale Spalten zum Durchtritt der Luft angeordnet, die dadurch gekennzeichnet sind, dass die Teilblätter während der Hintour als Widerstandsläufer und als Auftriebsläufer wirkend ausgebildet werden.These The object is achieved by a Wind power rotor with a rotatable about a vertical central axis Rotor, with at least three pairs of wings essentially radially arranged rotor blades, the rotor in the same size Divide sectors, the rotor blades divided into several sub-sheets are. Between the part sheets are vertical columns arranged to allow the passage of air through it are characterized in that the partial sheets during the return as resistance runner and as a buoyancy runner be formed acting.
Durch Kombination dieser beiden Wirkprinzipien lassen sich gegenüber konventionellen Vertikalrotoren erhebliche Wirkungsgradverbesserungen erzielen.By Combination of these two principles of action can be compared to conventional ones Vertical rotors achieve significant efficiency improvements.
Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.advantageous Embodiments are the subject of the dependent claims.
Besonders bevorzugt ist es, wenn die Teilblätter des Windkraftrotors derart optimiert werden, dass ihr strömungstechnischer Widerstand oder ihr strömungstechnischer Auftrieb bei der Hintour maximiert und ihr strömungstechnischer Widerstand bei der Rücktour minimiert wird.Especially it is preferred if the blades of the wind power rotor so be optimized that you fluidic Resistance or their fluidic Buoyancy at the rear maximizes and their aerodynamic drag on the return trip is minimized.

Die in radialer Richtung benachbarten Teilblätter weisen nach einer bevorzugten Ausführungsform gleiche Abstände zueinander auf.The in the radial direction adjacent partial sheets have a preferred embodiment same distances to each other.
Soweit unter Berücksichtigung aller weiteren Parameter, wie Profilierung, Zahl der Teilblätter etc., strömungstechnisch günstig, können die in radialer Richtung benachbarten Teilblätter auch unterschiedliche Abstände zueinander aufweisen.So far considering all other parameters, such as profiling, number of parts sheets, etc., fluidically Cheap, can the radially adjacent parts of the leaves also different distances to each other.
Gleiches gilt für die Profilierung der Teilblätter, die bei allen Teilblättern gleich oder unterschiedlich ausgebildet sein kann. Aus Symmetriegründen sollten jedoch nur die Teilblätter jedes Sektors und nicht in Umfangsrichtung verteilten Teilblätter unterschiedliche Profilierungen aufweisen, da es ansonsten zu Unwuchten kommt.The same applies to the profiling of the partial sheets, the with all partial sheets may be the same or different. For reasons of symmetry should but only the part sheets each sector and non-circumferentially distributed sub-sheets are different Profiling, otherwise it comes to imbalances.
