Patent ID: 8770917

Claim:
A wind power generation system, comprising: an air supply system; a composite structure with a turbofan; a plurality of generator components; a control device; and an air passage well, wherein the air supply system is configured to rise a flow of wind which enters into the wind power generation system; a wind supply funnel in the air supply system is set in a bottom of the composite structure with the turbofan; the composite structure with the turbofan is set in an interior of the air passage well; the flow of wind which is raised drives the composite structure with the turbofan to rotate; an operating gear ring connected to the composite structure with the turbofan rotates with it, and then drives a small gear in a generator component which engages with the operating gear ring to rotate with high speed; and a generator begins to generate electricity when a required rotary speed of an electric generating set is achieved, and wherein the composite structure with the turbofan includes a traveling rail, a turbofan, a seal groove for grease, a starter, and an electromagnetic brake, and wherein the turbofan is assembled by a plurality of vanes which are spirally fixed on an inner wall and an outer wall of a main body, an included angle between the vanes and a horizontal plane is 75° , and the vanes on the inner and outer walls are mounted on the inner wall and the outer wall of the main body oppositely and interlacedly with a proportion of 1:2.
