Abstract

La divulgation se rapporte à des centrales éoliennes, en particulier des dispositifs entraînés par le vent. La présente invention concerne un dispositif éolien qui convertit l'énergie éolienne en un mouvement rotatif. La conception de dispositif consiste en un corps dans lequel un arbre est installé verticalement, en rotation axiale, et sur lequel une roue en forme de disque est fixée à un angle incliné. L'angle d'inclinaison de la roue par rapport à l'axe vertical de l'arbre est fixe ou variable. Le vent ou l'air entrant s'écoulant à travers les orifices (éléments de guidage) du corps est dirigé vers le côté gauche ou droit de la roue, et en fonction de l'emplacement des éléments de guidage, ledit flux de vent/air entrant fait tourner la roue montée sur l'arbre. D'autres dispositifs nécessitant un mouvement rotatif, tels que des générateurs électriques ou équipement similaire, peuvent être connectés aux extrémités de l'arbre rotatif faisant saillie à partir du corps. Le dispositif est de conception simple et facile à entretenir.
