Description
Die Erfindung betrifft eine Windradanlage zur Energieerzeugung, mit einem Turm, einer an der Spitze des Turms um eine senkrechte Achse drehbar gelagerten und den Stromgenerator aufnehmenden Gondel, wenigsten drei an der Nabe des Rotors angeordneten Rotorblättern sowie am Ende der Rotorblätter in radialem Abstand voneinander angeordneten kreisförmigen Ringen, zwischen denen zur Erhöhung des auf den Rotor einwirkenden Drehmoments eine Vielzahl von Leitschaufeln angeordnet sind.The The invention relates to a wind turbine plant for power generation, with a tower, one at the top of the tower around a vertical axis rotatably mounted and the power generator receiving nacelle, at least three arranged on the hub of the rotor rotor blades and at the end of the rotor blades at a radial distance from each other arranged circular rings, between which increase of the torque acting on the rotor, a plurality of vanes are arranged.

Durch die Anordnung zusätzlicher Leitschaufeln an der Peripherie der Rotorblätter kann die Leistung eines Windrades erheblich gesteigert werden. Bei Windrädern mit relativ kurzen Rotorblättern lässt sich eine stabile Konstruktion verwirklichen. Wenn jedoch die Rotorblätter sehr lang sind, wie das bei den heute üblichen Windrädern der Fall ist, ist die Ringkonstruktion mit den zusätzlichen Leitschaufeln wegen ihrer großen Angriffsfläche sehr hohen Windkräften ausgesetzt, so dass das Windrad instabil wird und leicht Schaden nehmen kann.By the arrangement of additional vanes on the periphery The rotor blades can significantly increase the performance of a wind turbine be increased. For wind turbines with relatively short rotor blades can a stable construction be realized. If However, the rotor blades are very long, as in the usual today Wind turbines is the case, the ring construction is with the additional vanes because of their large Attack surface exposed to very high wind forces, so that the wind turbine becomes unstable and can easily be damaged.
Der Erfindung liegt die Aufgabe zugrunde, eine Windradanlage mit dem eingangs genannten Aufbau so auszugestalten, dass sie auch bei den heute üblichen großen Windrädern mit verhältnismäßig langen Rotorflügeln realisiert werden kann.Of the Invention is the object of a wind turbine with the The structure mentioned above in such a way that they also in today's usual big wind turbines with relative long rotor blades can be realized.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass an der Gondel in Verlängerung der Rotorachse ein Stabilisierungsrohr angeordnet ist, an dessen Ende Stangen oder Seile angebracht sind, die mit den am Ende der Rotorblätter angeordneten Ringen verbunden sind.These The object is achieved according to the invention that at the nacelle in extension of the rotor axis a stabilizing tube is arranged, at the end of rods or ropes are attached, the connected to the rings arranged at the end of the rotor blades are.
Je nach Ausführung dieser Stabilisierungskonstruktion lassen sich auf diese Weise auch Windräder mit sehr großem Durchmesser realisieren, indem beispielsweise die Länge des Stabilisierungsrohres und die Anzahl der Stabilisierungsstangen und/oder Seile entsprechend den jeweiligen Anforderungen variiert werden.ever after execution of this stabilization construction leave In this way, wind turbines with very large Realize diameter by, for example, the length of the stabilizing tube and the number of stabilizing rods and / or Ropes can be varied according to the respective requirements.
In zweckmäßiger Ausgestaltung der Erfindung kann eine zusätzliche Stabilisierung des Systems dadurch erreicht werden, dass die Spitze des Stabilisierungsrohres auf einem von Stützstangen getragenen Lager ruht, wobei die Stützstangen sich auf einem unterhalb des äußeren Ringes an dem Turm synchron mit der Gondel drehbar gelagerten Ausleger abstützen. Diese zusätzliche Lagerung der Spitze des Stabilisierungsrohres ermöglicht es, die auf das Stabilisierungsrohr einwirkenden Biegekräfte wesentlich zu reduzieren.In expedient embodiment of the invention can thereby achieving additional stabilization of the system be that the tip of the stabilization tube on one of Support rods supported bearing rests, with the support rods on one below the outer ring supporting the tower rotatably mounted boom synchronously with the nacelle. This additional storage of the tip of the stabilization tube allows it to act on the stabilizing tube Significantly reduce bending forces.
Der sich synchron mit der Gondel drehende Ausleger dient nicht nur zur Abstützung und zur Stabilisierung des Systems, sondern kann darüber hinaus auch zu anderen Zwecken dienen. Beispielsweise kann auf dem Ausleger eine Bremsvorrichtung angeordnet sein, die mit einem Teil der Ringkonstruktion in mechanischen Eingriff kommen kann. Dadurch wird es möglich, im Bedarfsfall das Windrad mechanisch abzubremsen und/oder das Windrad im Stillstand mechanisch zu blockieren.Of the Synchronous with the nacelle rotating boom is not just for Support and stabilization of the system, but may also be used for other purposes. For example can be arranged on the boom, a braking device, the come into mechanical engagement with a part of the ring construction can. This makes it possible, if necessary, the wind turbine mechanically decelerate and / or the wind turbine at a standstill mechanically to block.
Ebenso eröffnet der Ausleger die Möglichkeit, auf dem Ausleger den Statorteil eines oder mehrerer Lineargeneratoren anzuordnen, wobei der rotierende äußere Ring des Windrades den Rotorteil der Lineargeneratoren bildet. Diese Lineargeneratoren können für die zusätzliche Energiegewinnung genutzt werden, oder aber im Bedarfsfall auch als elektrische Bremse für das Windrad dienen.As well the boom opens up the possibility of being on the Cantilever to arrange the stator part of one or more linear generators, the rotating outer ring of the windmill forms the rotor part of the linear generators. These linear generators can be used for additional energy, or in case of need also as electric brake for to serve the windmill.
Die Ringkonstruktion kann auch so ausgeführt sein, dass ein beispielsweise aus einem Rohr bestehender Ring zwischen zwei in Reibkontakt mit diesem Ring einander gegenüber stehenden, um vertikale Achsen drehbaren Antriebsrädern steht, durch die weitere Rotationsgeneratoren angetrieben werden.The Ring construction can also be designed so that a for example, consisting of a pipe ring between two in Frictional contact with this ring facing each other, about vertical axes rotatable drive wheels, through the other rotation generators are driven.
