Disclosed is a wind power generating apparatus in which windmill blades are mounted in a multi-stage fashion to a rotating shaft while being spaced apart from one another to efficiently generate wind power. Each windmill blade includes blade bodies mounted to the rotating shaft, and provided with wind pressure adjusting holes, wind pressure adjusting plates coupled to each blade body, and connected together to a wire, each wind pressure adjusting plate being slidable along guides respectively arranged at opposite sides of the associated wind pressure adjusting hole to adjust an opening degree of the wind pressure adjusting hole, elastic members each adapted to connect one end of the associated wire to the associated blade body, and winches each adapted to connect the other end of the associated blade body, the winches being mounted to a single shaft to simultaneously wind or unwind all wire.

L'invention porte sur un aérogénérateur dans lequel les pales sont montées de manière étagée sur un arbre rotatif et sont espacées les unes des autres de manière à générer efficacement l'énergie éolienne. Chaque pale comporte des corps montés sur l'arbre rotatif qui sont pourvus de trous pour le réglage de la pression du vent. Des plaques de réglage de la pression du vent sont couplées à chaque corps des pales et raccordées à un câble, chacune de ces plaques pouvant coulisser le long des guides respectifs disposés au niveau des côtés opposés du trou de réglage associé afin de régler un degré d'ouverture du trou. Des éléments élastiques sont adaptés pour raccorder une extrémité du câble associé au corps associé de la pale. Des treuils sont adaptés pour raccorder l'autre extrémité du câble associé au corps associé de la pale, ces treuils étant montés sur un arbre unique par rapport à la totalité du câble enroulé ou déroulé.
