Abstract

L'invention concerne une méthode permettant d'aligner une pale rotative avec la direction du vent grâce à celui-ci en cas de grand vent. Les trois premières pales rotatives (3 à 5) sont attachées à un corps rotatif pouvant tourner (2) de façon à être centrées sur un arbre de rotation (1). Un arbre de direction du vent (6) peut tourner par rapport à l'arbre de rotation (1) en fonction de la direction de la force du vent sur une plaque de détection de la direction du vent (61). Une roue dentée fixe (7) est fixée sur l'arbre de direction du vent (6). Un mécanisme d'entraînement de clavette (13) permet à un premier élément clavette (11) de s'engager dans les premières parties d'engagement respectives (81, 91) d'une première et d'une deuxième roue dentée mobile (8, 9) en temps normal. Dans cet état, le corps rotatif (2) peut tourner grâce à la force du vent sur les pales rotatives (3 à 5). En cas de grand vent, le premier élément clavette (11) est retiré des premières parties d'engagement respectives (81, 91). Un deuxième élément clavette (12) est ensuite engagé dans les deuxièmes parties d'engagement respectives (82, 92) des première et deuxième roues dentées mobiles (8, 9). Dans cet état, chacune des pales rotatives (3 à 5) se place parallèlement à la direction du vent.
