Abstract

La présente invention a pour but de fournir un dispositif de génération d'énergie éolienne qui est pourvu d'éoliennes Savonius à étages multiples dans la direction avant-arrière, qui permet aux éoliennes de tourner efficacement contre le vent venant de n'importe quelle direction et qui améliore le rendement de génération d'énergie. Pour atteindre ce but, trois unités de génération d'énergie éolienne (200A - 200C), ayant chacune deux éoliennes Savonius (210) disposées côte à côte, sont agencées de façon à former un triangle sensiblement équilatéral. Un espace étroit (S) est ménagé entre les éoliennes à l'étage avant par rapport à une direction du vent (W1), l'énergie éolienne passant de l'avant à l'arrière étant reçue par des auges internes de réception de vent (213) de telle sorte que l'éolienne, sur un côté, tourne dans le sens des aiguilles d'une montre, et que l'éolienne, sur l'autre côté, tourne dans le sens inverse des aiguilles d'une montre. À l'étage central, une énergie éolienne passant par l'avant est reçue par des auges externes de réception de vent de telle sorte que l'éolienne, sur un côté, tourne dans le sens inverse des aiguilles d'une montre, et que l'éolienne, sur l'autre côté, tourne dans le sens des aiguilles d'une montre. À l'étage arrière, l'énergie éolienne ayant traversé l'espace (S) à l'étage avant est reçue par des auges internes de réception de vent de telle sorte que l'éolienne, sur un côté, tourne dans le sens des aiguilles d'une montre, et que l'éolienne, sur l'autre côté, tourne dans le sens inverse des aiguilles d'une montre. En outre, en vue par l'avant, chacune des auges internes de réception de vent à l'étage central chevauche partiellement l'auge externe de réception de vent sur le même côté à l'étage avant, et chacune des auges externes de réception de vent à l'étage arrière chevauche partiellement l'auge interne de réception de vent sur le même côté à l'étage avant.
