Moving vane 1 overcomes the spring force of back-moving spring 22 under wind pressure effect, and moving vane 1 rotates along blade bearing pin 23 makes blade
Wind area reduce, then rotor and center rotating speed will reduce, and ensure that brake apparatus in safe speed of rotation operated within range,
So as to ensure that the energy is saved in wind power generation plant normal work, the effect for reducing brake under the conditions of wind speed is very big；When wind speed is extensive
When multiple normal, the spring force of back-moving spring 22 is more than the wind pressure on moving vane 1, and moving vane 2 rotates along blade bearing pin 23
Increase the wind area of blade, simultaneously because the effect of centrifugal hammer pin back-moving spring 28, makes centrifugal hammer pin 27 and push back
Space minimum position in moving vane limit body 26, while restriction effect of the blade neck of blade 1 to moving vane is fixed,
Prevent to fix blade and moving vane forms blade and had from continuing to relatively rotate during maximum wind area, now rotor and central shaft
Faster rotational speed, and brake apparatus is in safe speed of rotation operated within range, it is achieved thereby that wind power generation plant is in the smaller bar of wind-force
Wind energy is made full use of under part.
