Abstract
Description
Die Erfindung betrifft eine Windkraftanlage nach Art eines Wirbel- oder Tornadoturms. Die erfindungsgemäße Windkraftanlage dient der Umwandlung der mechanischen wind- in elektrische Energie.The invention relates to a wind turbine in the manner of a whirlwind or tornado tower. The wind turbine according to the invention serves to convert the mechanical wind energy into electrical energy.
Es ist bekannt, Windenergie in elektrische Energie umzuwandeln. Eine Möglichkeit besteht darin, Wind tangential in das Innere einer Röhre zu leiten, so dass ein künstlicher tornadoähnlicher Wirbel gebildet wird, der durch die Öffnung am oberen „distalen” Ende der Röhre aufsteigt und vom das Röhrenende überstreichenden Wind abgetrieben wird. Im Kern des künstlichen Wirbels entsteht ein Unterdruck. Indem im das „proximale” Ende der Röhre bildenden Boden eine Turbine angeordnet ist, die von einer mittels des Unterdrucks im Wirbelkern aus einer Luftkammer angesaugten Luftströmung angetrieben wird, wird die kinetische Energie der Luftströmung in Elektroenergie umgewandelt. Ein derartiger Tornadoturm ist beispielsweise in der
Daraus ergibt sich als Aufgabe der Erfindung, auf einfache und effiziente Weise den Wirkungsgrad von Windkraftanlagen des Tornadoturmtyps zu erhöhen.It follows as an object of the invention to increase the efficiency of wind turbines of Tornadoturmtyps in a simple and efficient manner.
Die Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Demnach wird eine Windkraftanlage nach Art eines Wirbel- oder Tornadoturmes mit einem Saugbereich und einem darüber angeordneten Wirbel- oder Turmbereich vorgeschlagen, die durch einen Strömungskanal miteinander verbunden sind, in dem ein Repeller angeordnet ist, der über eine Welle einen Generator antreibt. Der Turmbereich ist mit einer luvseitig außermittig angeordneten, mit einer tangential vom Turmbereich wegstrebenden und der Windrichtung entgegen gerichteten Leiteinrichtung versehen und weist eine am Boden des Turmbereiches ansetzende vertikale Öffnung auf. In einem Abstand zum Turmbereich ist luvseitig ein Sogschirm senkrecht und quer zur Windrichtung angeordnet. Vorteilhafte Ausgestaltungen und Weiterbildungen der erfindungsgemäßen Windkraftanlage ergeben sich aus den Unteransprüchen. Demnach kann in einer ersten vorteilhaften Weiterbildung der Erfindung der Sogschirm höhen- und abstandsverstellbar am Turmbereich befestigt sein. Eine vorteilhafte Ausbildung der erfindungsgemäßen Windkraftanlage ergibt sich, indem der lichte Abstand des Sogschirmes vom Turmbereich ca. einen Turmdurchmesser bis ca. drei Turmdurchmesser beträgt und die Unterkante des Sogschirmes bei ca. 5/10 bis 7/10 der Turmhöhe eingerichtet ist, wobei der Sogschirm eine Höhe von ca. dem 1,5- bis 3,7-fachen der Turmhöhe und eine Breite von ca. dem 2,3- bis 3-fachen des Turmdurchmessers aufweist.The object is achieved by the features of
Eine weitere vorteilhafte Weiterbildung der Erfindung besteht darin, dass zwei Wirbeltürme mit einem gemeinsamen Sogschirm versehen sind, wobei insbesondere die luvseitigen vertikalen Öffnungen der Wirbeltürme symmetrisch und weitestmöglich voneinander entfernt angeordnet sind.A further advantageous embodiment of the invention is that two vortex towers are provided with a common suction screen, wherein in particular the windward vertical openings of the vortex towers are arranged symmetrically and as far as possible from each other.
Die Erfindung wird im Folgenden in Form eines bevorzugten Ausführungsbeispiels anhand der Zeichnung beschrieben. Die Zeichnung zeigt inThe invention will be described below in the form of a preferred embodiment with reference to the drawing. The drawing shows in
