Description
Technical field
This utility model relates to noise control technical field, particularly relates to a kind of noise reduction soundproof wall.
Background technology
Along with social development, the creation of various equipment and use, bring prosperity and progress to the mankind, but the most also create more and more and the strongest noises.Audition not only can be caused damage by noise, moreover it is possible to induces multiple carcinogenic fatal disease, has also disturbed the life and work of people.
In order to reduce noise, noise source, the propagation path of noise and reception source three are isolated or protect, blocked by the energy of noise or absorb by surrounding environment and the impact of the mankind, main noise control mode.Therefore on the propagation path of noise, sound-absorbing and sound insulation then become a very urgent problems.
Conventional noise reduction mode be before the isolation of propagation path on plus noise reduction porous plate, this simply plays a role in terms of sound-absorbing, but is not very big to sound insulation aspect role, and sound-absorbing can not have both with sound insulation simultaneously, and noise reduction is poor.
Existing conventional noise reduction metope installs porous noise reducing plate additional in the inner side of isolation wall, plays the function of sound insulation just with the rock wool in case.For as some casings of generating set, owing to noise and the vibrations of equipment self generation are very big, conventional noise reducing plate cannot play enough sound deadenings, the most still can produce the biggest noise in the outside of generating set.
And on the one hand the generating set casing of routine only takes into account the sound absorption function of casing, and ignore the effect of sound insulation.The sound wave of generator set device product is more complicated, has different frequencies, will solve the biggest noise reduction, it is necessary to thickeies noise reducing plate, also increases the cost of noise reduction simultaneously.
Utility model content
This utility model, mainly solving the technical problems that provide a kind of noise reduction soundproof wall, uses three-layer protection design, incorporates the function of sound-absorbing and sound insulation, add noise reduction capability, and sound-absorbing material can absorb noise twice, is effectively increased sound-absorbing efficiency.
For solving above-mentioned technical problem, the technical scheme that this utility model uses is: provide a kind of noise reduction soundproof wall, including the wall face of: casing and be located at the quiet metope inside wall face, described quiet metope includes support, one group of dual sided porous plate of internal layer, middle air layer and is located at the damping fire prevention rubber layer of air layer outer surface, being filled with one group of sound-absorbing material between described dual sided porous plate and air layer, described support is for supporting sound-absorbing material and damping fire prevention rubber layer and both separating the air layer in the middle of being formed.
In one preferred embodiment of this utility model, described dual sided porous plate is arranged towards the inside of casing.
In one preferred embodiment of this utility model, described dual sided porous plate is evenly equipped with multiple aperture.
In one preferred embodiment of this utility model, described sound-absorbing material is flame resistant glass cotton or non-woven fabrics.
In one preferred embodiment of this utility model, described sound-absorbing material equi-spaced apart is distributed between dual sided porous plate and air layer.
The beneficial effects of the utility model are: this utility model noise reduction soundproof wall uses three-layer protection design, incorporates the function of sound-absorbing and sound insulation, adds noise reduction capability, and sound-absorbing material can absorb noise twice, is effectively increased sound-absorbing efficiency.
Accompanying drawing explanation
In order to be illustrated more clearly that the technical scheme in this utility model embodiment, in describing embodiment below, the required accompanying drawing used is briefly described, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation of noise reduction soundproof wall one of the present utility model preferred embodiment；
In accompanying drawing, the labelling of each parts is as follows: 1, wall face, and 2, damping fire prevention rubber layer, 3, air layer, 4, support, 5, sound-absorbing material, 6, dual sided porous plate.
Detailed description of the invention
Technical scheme in this utility model embodiment will be clearly and completely described below, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, all other embodiments that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Referring to Fig. 1, this utility model embodiment includes:
A kind of noise reduction soundproof wall, including the wall face 1 of: casing and be located at the quiet metope inside wall face 1.
Described quiet metope includes support 4, one group of dual sided porous plate 6 of internal layer, middle air layer 3 and is located at the damping fire prevention rubber layer 2 of air layer 3 outer surface.
One group it is filled with for the sound-absorbing material 5 absorbing partial noise between described dual sided porous plate 6 and air layer 3.Being evenly equipped with multiple aperture on described dual sided porous plate 6, described dual sided porous plate 6 is arranged towards the inside of casing, it is possible to effectively transmit noise.
Described sound-absorbing material 5 is flame resistant glass cotton or non-woven fabrics, has good sound-absorbing effect.Sound-absorbing material 5 equi-spaced apart is distributed between dual sided porous plate 6 and air layer 3.
Noise, for supporting sound-absorbing material 5 and damping fire prevention rubber layer 2 and both separating the air layer 3 of formation hollow form formed between, can be rebounded by described support 4, and partial noise is again repelled back sound-absorbing material 5 and is absorbed.
The sound-absorbing process of this utility model noise reduction soundproof wall is:
Quiet metope has overturned the design of traditional muting plate sound insulation, by front and back's three-layer protection, all of noise is allowed to first pass through dual sided porous plate 6, first absorbed by glass cotton sound-absorbing material 5, then by the space (air layer) 3 of hollow design, allow noise rebound again at internal echo and be delivered to glass cotton sound-absorbing material 5 and absorb；
In view of the 3rd pipe protection of noise, in the outside of air layer 3, then add one layer of novel damping fire prevention rubber-plastics material and carry out sound insulation, it is ensured that the noise that whole equipment produces, all absorbed inside quiet metope.
This utility model noise reduction soundproof wall provides the benefit that:
Employing three-layer protection designs, and incorporates the function of sound-absorbing and sound insulation, adds noise reduction capability, and sound-absorbing material can absorb noise twice, is effectively increased sound-absorbing efficiency.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure utilizing this utility model description to be made or equivalence flow process conversion; or directly or indirectly it is used in other relevant technical field, the most in like manner it is included in scope of patent protection of the present utility model.
