Abstract

The invention provides a wind power driving system. The wind power driving system comprises multiple groups of blade mechanisms and a rotary main shaft, wherein the multiple groups of blade mechanismsare rotatably arranged around a circle of the radius of the rotary main shaft; each group of blade mechanisms comprises blades and a rotary shaft assembly; the blades can be automatically variable inpitches and are mounted on the rotary shaft assembly; and each group of blade mechanisms synchronously rotate together with the rotary main shaft while locally rotating in a windward blowing action.The wind power driving system can automatically change the pitches to rotate without being driven by mechanical power under the wind speed of strong wind from grade 2 to grade 10; the rotation directions of the wind wheel blades and wind wheels are independent of the wind direction and the wind speed; and the automatic pitches changing structure of the wind wheel blades is simple, the blades can be mass produced, the production cost is reduced, and the production working environment is improved to the maximum extent.

Description

technical field

[0001] The invention relates to the technical field of wind power generation, in particular to a novel vertical-axis automatic pitch-variable wind drive system. Background technique

[0002] At present, the driving system of megawatt-level wind power generation is mainly based on the horizontal shaft transmission mechanism. Most of the blades of the horizontal axis fan are arranged in the form of trisection variable cross-section suspension. There are two systems with speed-up mechanism and without speed-up mechanism. They are also arranged in a straight line or side by side on a rotary nacelle that can rotate positively and negatively. , The rotary nacelle is connected through the yaw bearing with the ring gear, the friction disc, the brake, and the drive to realize the start or stop of the nacelle when it rotates positively and negatively at any time. The disadvantages of its mechanical transmission system are the large size, heavy weight, complex transmis...
