Problems solved by technology

[0002] The development of wind power generators has become a very important way of global energy development. Parallel and vertical wind power generators are two basic ways. The development of parallel wind power generators is limited by transportation conditions, and the length of blades has reached the limit. It is very difficult to increase the power, and the conversion efficiency of wind energy is not high
The development of vertical wind turbines is affected by the balance of the force couples on both sides, and the power generation is always low. No matter from the "S" type or "H" wind turbines, the windward ability is poor, and the resistance is relatively large. There is no major breakthrough in technology, so develop slowly

Embodiment Construction

[0022] 1. start

[0023] In the stopped state, each brake device releases each windshield to be parallel to the wind direction. Start is to turn on the controller, brake the windshield on the downwind side but the windshield is still parallel to the wind direction, use the motor to drive the shaft to rotate, when a windshield on the leeward side reaches figure 1 When the central axis A-A', α=0°, the windshield brake works, and the windshield and the rotating arm are fixed. When the rotating shaft continues to rotate, the windshield is pushed by the wind force to start rotating the rotating arm and enters the normal working state, and each windshield enters in turn, and the motor stops pushing and turns to the power generation state to realize starting. (Downwind side windshield enters leeward side brake release enters normal cycle.)

[0024] 2. Normal work

[0025] The windshield on the downwind side is driven by the wind to generate power.

[0026] The windshield on the l...

Abstract

The invention relates to a self-adaption jogging wind-shield vertical shaft wind driven generator comprising a swiveling jib, an attaching jogging surface wind-shield blade, a braking device and a braking device controller. By changing the shape and the position of a wind-shield machine, the self-adaption jogging wind-shield vertical shaft wind driven generator unfolds a wind-shield on a downwind surface (working surface),and changes the direction of the wind-shield to parallel to wind direction on a leeside (resistance surface) so as to greatly reduce resistance, moreover, force couples positioned at two sides are not balanced any longer, thereby driving the generator to generate electricity; the attaching jogging surface wind-shield blade keeps the wind-shield in an ideal design direction all the time, and the braking device controller controls the braking device to work by an included angle between the wind direction and the swiveling jib, thereby not only ensuring the normal work of a whole system, but also automatically inducting and regulating the work of the braking device when the wind direction changes. The invention has simple structure, low cost and practical application prospect and ensures that super-power power generation capacity is possible due to the multilayer wind-shield.

Description

【Technical field】: [0001] The invention belongs to a brand new way of wind power generation. 【Background technique】: [0002] The development of wind power generators has become a very important way of global energy development. Parallel and vertical wind power generators are two basic ways. The development of parallel wind power generators is limited by transportation conditions, and the length of blades has reached the limit. It is very difficult to increase the power, and the conversion efficiency of wind energy is not high.
