Wind-driven generator group machinery space sound-insulating structure

Abstract

The invention discloses a cabin soundproof structure of a wind power generator group, which comprises a cabin case which is made of reinforce glass fiber material, wherein a soundproof flameproof material is coated on the inner wall and / or bottom wall of the cabin case. The invention can adsorb acoustic wave, reduce reflection wave because the sound adsorbing layer is rough-hole foaming polyethylene material after the technique scheme of the cabin soundproof structure of the wind power generator group is solved, which doesn't join reverberation. The staccato layer is thin-hole foaming and can effectively obstruct the transmission of acoustic wave and heat, thereby the noise level of the wind power generator group periphery can be effectively reduced, the fire and combustion of the glass fiber case of the generator group can be prevented, which insulates in the environment of low temperature.

Description

technical field [0001] The invention relates to a sound insulation structure of a nacelle of a wind power generating set. technical background [0002] When the wind turbine is running, its mechanical transmission system and cooling and exhaust system will generate noise, and most of the existing nacelles are made of reinforced glass fiber or aluminum plate, the sound insulation and noise reduction effect of these two materials is not ideal. And because the engine room is installed at a relatively high position, the vertical height from the ground is higher than 60 meters, and the glass fiber is not easy to fire and flame retardant. Once a fire occurs, it is extremely difficult to rescue due to the height of the engine room, high wind speed and material reasons. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a sound-insulating and fire-proof cabin sound-insulating structure of the wind p...
