Patent ID: 7528498

Claim:
A wind power system, comprising: a frame; a plurality of power modules installed in the frame, wherein a first respective power module is extractable from the frame through an extraction direction, the first respective power module having: an impeller having a spinning shaft perpendicular to the extraction direction and an impeller gear circumscribed around the impeller; a plurality of first wedging surfaces, wherein the respective wedging surface has a first side and a second side being relatively far from and relatively close to the spinning axle respectively; and a plurality of second wedging surfaces respectively spaced in-between and connected to the plurality of first wedging surfaces for enclosing the impeller, wherein the respective second wedging surface has a third side and a fourth side being relatively close to and relatively far from the spinning shaft respectively and is assembled with a transmission gear meshing with the impeller gear, wherein the first and second wedging surfaces of a first power module respectively manage to cooperate with a second wedging surface of a second respective power module and a first wedging surface of a third respective power module for fixing the first respective power module to the frame such that the impeller gear of the first respective power module assistantly drives respective impeller gears of the second and third respective power modules through a transmission gear of the second respective power module and the transmission gear of the second wedging surface cooperating with the third respective power module for generating a torque imparted to the generator; a generator connected to a fourth respective power module; and a wind guide member parallel to the extraction direction and rotatably mounting thereon the frame, thereby the frame adjustably rotating to receive a wind so that the respective impellers of the plurality of the power modules are optimally driven by the wind for generating a torque, which is imparted to the generator for generating an electricity.
