Abstract
The utility model relates to the structure of a sound attenuation wall surface of a transformer substation. The structure of the wall surface comprises a combined sound absorption layer, an air sound attenuation layer and a sound insulating layer which are arranged sequentially from outside to inside, wherein the edge of the combined sound absorption layer and the edge of the sound insulating layer are connected in a sealed mode through a framework, and interspace forms between the combined sound absorption layer and the sound insulating layer to form the air sound attenuation layer. Compared with the prior art, the structure of the sound attenuation wall surface of the transformer substation has the advantages of being good in sound attenuation effect, being not affected with damp easily, avoiding influence on the effect, and the like.
Description
Technical field
The utility model relates to a kind of noise reduction body of wall, especially relates to a kind of transformer station noise reduction metope structure.
Background technology
Noise pollution has become one of serious environmental problem in current Chinese Urbanization's evolution.Along with Chinese society development, country pays attention to more and more that people-oriented, social harmony and scientific development, more and more payes attention to national dwelling environment.Sound environment quality control will be the key subjects of new century sustainable development.
" green electrical network " and " green transformer station " will become urban distribution network and transformer station's design and construction developing direction, should the city glorious and resplendent, residential electricity consumption is protected, the comfortable harmony in city again, also resident's a slice peace and quiet.Therefore guarantee that the substation will become great technical problem in the city transformer station design and construction in the sound environment quality of locating, the key measure in the low noise transformer substation construction and technology path are one of them concrete contents.
How the existing sound absorption and insulation structure that reduces transformer station's noise is made up of perforated plate and sound absorption material.Perforated plate is because mechanical technology, and its through hole is difficult to reach the tiny intensive requirement of control low-frequency noise usually, and therefore the acoustically effective to the low-frequency noise of transformer station is not very desirable; Secondly, existing sound absorption material adopts sound absorption cotton more, and the perforated plate perforate is bigger, rainwater or steam very easily infiltrate in the plate, noise sound absorption cotton makes moist, and the acoustically effective of the sound absorption cotton after making moist can reduce greatly, so bigger decline can appear in the acoustically effective of porous sound absorption barrier in time.
The utility model content
Thereby the purpose of this utility model is exactly transformer station's noise reduction metope structure that a kind of good muffling effect, non-moisture-sensitive impact effect are provided for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of transformer station noise reduction metope structure, this metope structure comprises composite sound absorbing layer, air silencing plate and the soundproof course that ecto-entad sets gradually, described composite sound absorbing layer is connected by frame seal with the edge of soundproof course, between composite sound absorbing layer and soundproof course, leave the space, form described air silencing plate.
Described composite sound absorbing layer comprises the mineral wool flaggy that is positioned at the outside and is positioned at inboard foamed aluminium absorbent treatment, offers a plurality of through holes on the described mineral wool flaggy.
The aperture of described through hole is 5～15mm, and through hole is rectangular evenly to be arranged on the mineral wool flaggy.
The thickness of described mineral wool flaggy is 5～15mm, and the thickness of described foamed aluminium absorbent treatment is 10-15mm, and the thickness of described soundproof course is 20mm, and the thickness of described air silencing plate is 75-85mm.
Compared with prior art, the utility model at first absorbs by the noise of composite sound absorbing layer to transformer station, the unabsorbed noise of part passes the air silencing plate, can reflection take place on the surface of soundproof course enter the foamed aluminium absorbent treatment that is positioned at composite sound absorbing layer inboard again, carry out sound absorption again, while because reflected sound wave and the original sound wave of meeting interfere, can further be strengthened the effect of noise reduction in the air silencing plate.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of transformer station noise reduction metope structure, this metope structure comprise composite sound absorbing layer, air silencing plate 3 and the soundproof course 4 that ecto-entad sets gradually.The composite sound absorbing layer comprises inside and outside two-layer, is respectively the mineral wool flaggy 1 that is positioned at the outside and is positioned at inboard foamed aluminium absorbent treatment 2, offers a plurality of rectangular through holes of evenly arranging at mineral wool flaggy 1, and the aperture is between 5～15mm.The composite sound absorbing layer is connected by frame seal 5 with the edge of soundproof course 4, leaves certain thickness space between the two, forms air silencing plate 3.
The thickness that this noise reduction metope structure is every layer is: the thickness of mineral wool flaggy is between 5～15mm, and the thickness of foamed aluminium absorbent treatment is between 10-15mm, and the thickness of soundproof course is about 20mm, and the thickness of air silencing plate is between 75-85mm.
