Abstract: 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.

Abstract: An apparatus for generating power using wind energy, including connecting shafts arranged around a boss and rotatably supported by the boss, pinions each fitted around the associated connecting shaft to rotate along with the associated connecting shaft, rack housings each fixedly mounted to the boss near the associated pinion, rack gears each slidably received in the associated rack housing and engaged with the associated pinion, springs each fitted around a portion of the associated rack gear extending beyond the rack housing receiving the associated rack gear and adapted to urge the associated rack gear toward an end of the associated rack gear protruded from the associated rack housing, and spring force adjusting knobs each threadedly coupled to the protruded end of the associated rack gear and adapted to adjust a spring force of the associated spring.

Abstract: Disclosed is an apparatus for generating power using wind energy, which can automatically adjust the angle of blades in response to the force of wind applied to those blades, thereby achieving a maximum utilization of wind energy.
