A cooling type wind power generation equipment with speed limiting function

Abstract

The invention relates to heat dissipation type wind power generation equipment with a speed limiting function. The equipment comprises a fixing box, blades, a transmission shaft, a rotation shaft, a power generation device and a speed limiting mechanism, wherein a through hole is formed in one side of the fixing box, the transmission shaft penetrates through the through hole, and the transmissionshaft is in sliding and sealing connection with the through hole; the blades are arranged on one side, provided with the through hole, of the fixing box, the blades are arranged on the transmission shaft, and the rotation shaft is coaxially arranged with the transmission shaft; the power generation device is arranged at one end, far away from the transmission shaft, of the rotation shaft, and thetransmission shaft is connected with one end, far away from the power generation device, of the rotation shaft through a speed limiting mechanism; and a heat dissipation mechanism is further arrangedin the fixing box. The heat dissipation type wind power generation equipment with the speed limiting function achieves the speed limiting function through the speed limiting mechanism, and a heat dissipation function is achieved through the heat dissipation mechanism.

Description

technical field [0001] The invention relates to the field of wind energy equipment, in particular to a cooling type wind power generation equipment with speed limiting function. Background technique [0002] Wind generators are a common type of wind energy equipment. Wind generators convert the kinetic energy of wind into electrical energy. Wind energy is a clean and pollution-free renewable energy source. Using wind power to generate electricity is very environmentally friendly and has a huge wind energy reserve. It has been paid more and more attention by countries all over the world. [0003] During the operation of the wind turbine, the generator can generate electricity normally within the rated speed. When the speed is too fast, the generator will be overloaded, which will easily cause the generator to burn out. Most of the existing wind generators use brake pads to reduce If the speed is high, the brake pads will generate heat due to friction, and the life of the gen...

[0003] During the operation of the wind turbine, the generator can generate electricity normally within the rated speed. When the speed is too fast, the generator will be overloaded, which will easily cause the generator to burn out. Most of the existing wind turbines use brake pads to reduce speed, the brake pads will generate heat due to friction, and the life of the generator will be shortened if the generator is in a high temperature environment for a long time
