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
The present invention relates to a kind of machinery space sound-insulating structure of wind power generating set.
Technical background
Wind power generating set is when operation, and its machine driven system and cooling, air discharging system all can produce noise, and existing cabin mostly is made by reinforcing glass fiber or aluminium sheet, and the sound insulation erasure effect of these two kinds of materials is all very undesirable.Because the mounting point, cabin is higher, be higher than 60 meters again, and glass fibre is difficult for fire protection flame retarding apart from the vertical height on ground, in case breaking out of fire, because the height that the cabin is in, wind speed is big and material, extremely difficult rescue.
Summary of the invention
The objective of the invention is to is to overcome the deficiencies in the prior art, and providing a kind of is the sound insulation machinery space sound-insulating structure of frpf wind power generating set again.
The technological scheme that realizes above-mentioned purpose is: a kind of machinery space sound-insulating structure of wind power generating set, comprise the cabin case of making by the reinforcing glass lamination coating, and it is characterized in that, be covered with the sound isolating and flame-retardant material on the inwall of described cabin case and/or the diapire.
The machinery space sound-insulating structure of above-mentioned wind power generating set, wherein, described sound isolating and flame-retardant material is divided into inboard sound-absorption layer and covers heat insulation staccato layer on the sound-absorption layer.
The machinery space sound-insulating structure of above-mentioned wind power generating set, wherein, described sound-absorption layer is made for the gross porosity polyethylene foam-material, and described heat insulation staccato layer is made by the pore polyethylene foam-material, and they are bonding by adhesive between the two.
The machinery space sound-insulating structure of above-mentioned wind power generating set, wherein, described sound isolating and flame-retardant material also comprises one deck greaseproof paper, it sticks on the outer surface of gross porosity polyethylene foam-material or sound-absorption layer.
After having adopted the technical solution of machinery space sound-insulating structure of wind power generating set of the present invention, because sound-absorption layer is a gross porosity polyethylene foamed material, can absorb sound wave, reduce reflected wave, make it not participate in reverberation, the staccato layer is a pore polyethylene foamed material, can effectively intercept the propagation of sound wave and heat, therefore can reduce wind power generating set noise level on every side effectively; Avoid the glass fibre cover catching fire of unit; In low temperature environment, can play insulation effect.
Description of drawings
Fig. 1 is the perspective view of the machinery space sound-insulating structure of wind power generating set of the present invention;
Fig. 2 is the cross-sectional view of the machinery space sound-insulating structure of wind power generating set of the present invention.
Embodiment
See also Fig. 1 and 2, the machinery space sound-insulating structure of a kind of wind power generating set of the present invention comprises the sound isolating and flame-retardant material 2 on the cabin case of being made by the reinforcing glass lamination coating 1 and the inwall 10 that sticks on cabin case 1 and the diapire 11.This sound isolating and flame-retardant material sticks on the encloser inner wall of cabin by special adhesive is bonding.
Sound isolating and flame-retardant material 2 is divided into inboard sound-absorption layer 21 and covers heat insulation staccato layer 22 on the sound-absorption layer 21.Sound-absorption layer 21 is made for the gross porosity polyethylene foam-material, and heat insulation staccato layer 22 is made by the pore polyethylene foam-material, and they are bonding by adhesive between the two.
Sound isolating and flame-retardant material 2 also comprises one deck greaseproof paper 23, and it sticks on the outer surface that sound-absorption layer 21 is the gross porosity polyethylene foam-material, is sucked by sound-absorption layer 21 and influences sound-absorbing effect to prevent greasy dirt in the cabin.
After having sticked the sound isolating and flame-retardant material on the inwall of cabin, can reduce wind power generating set noise level on every side effectively; Avoid the glass fibre cover catching fire of unit; In low temperature environment, can play insulation effect.
Above embodiment is only for the usefulness that the present invention is described, but not limitation of the present invention, person skilled in the relevant technique, under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technological schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
