Safe wind driven generator with overspeed protection function

Abstract

The invention relates to a safe wind driven generator with an overspeed protection function. The safe wind driven generator comprises a body, a generator, a transmission shaft, a repair pipe, a sealing cover and fan blades, and further comprises a speed reduction mechanism and a locking mechanism. The speed reduction mechanism comprises a drive shaft, a wind cup, a trigger assembly, a connecting bearing, a friction block and two lifting rods. The locking mechanism comprises a sealing cylinder, a piston block, a sealing casing pipe, a gas conveying pipe, a gas cylinder, a fixed plate and a locating hole. The trigger assembly comprises a sliding casing pipe, a spring, two rotating rods, two connecting rods and two gravity blocks. In the safe wind driven generator with the overspeed protection function, the rotating speed of the transmission shaft can be controlled through the speed reduction mechanism, the probability that overspeed happens to the wind driven generator is reduced, and the failure rate of the wind driven generator is reduced; and the sealing cover can be locked by the locking mechanism, operators cannot achieve repair outside the wind driven generator in the windy weather, and safety of the wind driven generator is improved.

Description

technical field [0001] The invention relates to the field of new energy equipment, in particular to a safe wind power generator with an overspeed protection function. Background technique [0002] A wind turbine is a power device that converts wind energy into mechanical work, which drives the rotor to rotate, and finally outputs alternating current. Wind turbines are generally composed of components such as wind rotors, generators, steering devices, towers, speed limiting safety mechanisms, and energy storage devices. The working principle of a wind turbine is relatively simple. The wind rotor rotates under the action of the wind, which converts the kinetic energy of the wind into the mechanical energy of the wind rotor shaft, and the generator rotates to generate electricity under the drive of the wind rotor shaft.

Problems solved by technology

[0003] When the wind power generator of the prior art is in use, if the wind force is too large, it will cause the overspeed phenomenon of the wind power wind machine, which increases the failure rate of the wind power generator. Not only that, but when the wind power generator of the prior art is in use, If the operator goes out of the cabin for maintenance in windy weather, it will increase the danger of maintenance
