Abstract
The utility model discloses an inner wall surface of various machinery rooms and soundproof covers used for abating noise, and the inner wall surface comprises a wall body, wherein, a plurality of sound absorption cavities are evenly distributed in the wall body, and a sound absorption groove corresponding to each sound absorption cavity is arranged on the inner wall surface and is communicated with each sound absorption cavity. Because a plurality of sound absorption cavities with sound absorption grooves are designed, the inner wall surface forms resonant sound absorption to effectively absorb low-frequency noise; with a solid sound absorption structure formed by sound absorption material, waterproof and dustproof material, and perforated panels, the inner wall surface also has favorable effect of high-frequency noise absorption to form a highly efficient wide-frequency soundproofing structure, and has large amount of sound absorption and insulation and marked effect of noise reduction.
Description
Technical field
The utility model relates to a kind of construction wall, especially relates to a kind of interior metope with sound absorption function.
Background technology
The machine room and the sound insulation enclosure that are used for various noise abatement at present, metope generally adopts the solid sound absorber of orifice plate in the sound absorption that use in equipment wideband noise places such as particularly various petroleum gas booster stations, CNG gas station, engineering machinery, dynamic power machine, and after perforated panel, install sound absorption material additional, reach the purpose of sound absorption reduction.But the general frequency broad of noise in that above-mentioned place produced not only has high-frequency noise, also has a large amount of low-frequency noises, and the solid sound absorber of above-mentioned orifice plate has effect preferably for the absorbing high-frequency noise, but makes an uproar for absorbing low frequency that then effect is relatively poor.
The utility model content
The shortcoming that the purpose of this utility model is to overcome above-mentioned prior art provide a kind of can the absorbing high-frequency noise, can absorb the absorbing wall of low-frequency noise again, this absorbing wall sound absorption frequency range broad, noise reduction is obvious.
The purpose of this utility model is achieved in that
Metope in a kind of noise elimination comprises body of wall, wherein is provided with some sound absorption cavitys of evenly arranging in body of wall, is provided with the sound absorption groove that is communicated with it with respect to each sound absorption cavity on inner metope.
Be preferably, described sound absorption cavity is a rectangular cavities;
As further improvement of the utility model, this sound absorption cavity from inside to outside is made of sound absorption material, water proof and dust proof material and perforated panel successively;
In order to arrange the sound absorption cavity better, between adjacent sound absorption cavity, be provided with the connection skeleton.
The utility model has following advantage than prior art:
The utility model has formed resonance sound-absorbing because having designed several has the sound absorption cavity of the groove that absorbs sound, and can absorb low-frequency noise effectively, and increase the sound absorption area; Be aided with the solid sound absorption construction that is made of sound absorption material, water proof and dust proof material and perforated panel, also have effect preferably for the absorption of high-frequency noise, formed the high-efficiency broadband noise elimination structure, sound absorption, sound insulation factor are bigger, and noise reduction is obvious.
Description of drawings
Fig. 1 is a structural representation of the present utility model.Among the figure, body of wall 1, sound absorption cavity 2, inner metope 3, sound absorption groove 4, sound absorption material 5, water proof and dust proof material 6, perforated panel 7, connection skeleton 8.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details; but protection domain of the present utility model has more than and is limited to these examples; such as, the change to the change of solid sound absorption construction or sound absorption material, water proof and dust proof material all belongs to protection domain of the present utility model.
Embodiment: metope in a kind of noise elimination, comprise body of wall 1, wherein in body of wall 1, be provided with some rectangle sound absorption cavitys 2 of evenly arranging, on inner metope 3, be provided with the sound absorption groove 4 that is communicated with it with respect to each sound absorption cavity 2, wherein, this sound absorption cavity 2 from inside to outside is made of sound absorption material 5, water proof and dust proof material 6 and perforated panel 7 successively, is provided with to connect skeleton 8 between adjacent sound absorption cavity 2.
Wherein, sound absorption material can be selected sponge well known in the art etc. for use; The water proof and dust proof material can be selected glass cloth well known in the art etc. for use.
