Wind power generation device

Abstract

The invention relates to the field of wind power generation, and particularly discloses a wind power generation device. The device comprises a generator and a square tank, the lower portion of the generator is located in the square tank, a vertical shock absorber is arranged between the bottom plate of the square tank and the bottom surface of the shell of the generator, and transverse shock absorbers are arranged between the four side plates of the square tank and the side surfaces of the shell of the generator; the vertical shock absorber comprises a first shock absorbing mechanism and second shock absorbing mechanisms, wherein the first shock absorbing mechanism comprises an outer sleeve cylinder, a base assembly and a fixing assembly; the second shock absorbing mechanisms comprise twoelastic shock absorbing plates symmetrically fixed to the shell of the generator and pouring bags arranged between the elastic shock absorbing plates and the bottom plate of the square tank, and the transverse shock absorbers comprise outer cylinders fixed to the side plates of the square tank and inner cylinders slidably arranged in the outer cylinders in a sleeved mode. By means of the wind power generation device, shock absorbing and noise reduction can be effectively conducted on the generator, occurrence of resonance between the generator and external environment is prevented, smooth andstable operation of the generation device is ensured, the noise produced by the generator during work is reduced, and the noise pollution is reduced.

Description

technical field [0001] The invention relates to the field of wind power generation, in particular to a wind power generation device. Background technique [0002] Wind power generation device is commonly used power generation equipment, which generally includes blades, main shaft, gear mechanism and generator. work to generate electricity. After the generator with rotor structure is installed in the wind farm, due to the influence of the external environment, it is easy to cause resonance between various components. When the internal structure of the generator resonates with the external environment, the power generation device will be seriously damaged, and the consequences will be serious. At present, although there are measures to dampen the vibration of the generator by using vibration-damping pads, damping springs and other devices in this field, the vibration-damping effects are not ideal, which seriously affects the smooth and stable operation of the power generation...

After the generator with rotor structure is installed in the wind farm, due to the influence of the external environment, it is easy to cause resonance between various components. When the internal structure of the generator resonates with the external environment, the power generation device will be seriously damaged, and the consequences will be serious.

At present, although there are measures to dampen the vibration of the generator by using vibration-damping pads, damping springs and other devices in this field, the vibration-damping effects are not ideal, which seriously affects the smooth and stable operation of the power generation device, and also produces sound polution
