Description
Technical Field
The utility model relates to the technical field of sound attenuation plates, in particular to a track traffic sound attenuation plate.
Background
Rail traffic refers to a type of vehicle or transportation system in which an operating vehicle needs to travel on a particular track. Common rail transit is the traditional railway, subway, light rail and tramcar, and in addition, the novel rail transit such as magnetic suspension rail system, monorail system and the like.
The rail transit vehicle can produce great noise when driving, especially the subway is because at sealed underground space, and the noise can be reflected back and forth in underground space, influences people's waiting experience, need absorb the noise and fall.
The existing silencer structure is complex, poor in silencing effect and needs to be further improved.
Disclosure of Invention
The utility model aims to solve the technical problem of overcoming the difficulty and providing the track traffic silencing plate with simple structure and good silencing effect.
In order to solve the technical problems, the technical scheme provided by the utility model is as follows: the utility model provides a track traffic sound attenuation board, includes the sound attenuation board body and locates the frame at sound attenuation board body edge, the sound attenuation board body includes the plate body and locates a plurality of amortization hole on the plate body, be equipped with the expansion hole with the amortization hole intercommunication in the plate body, amortization hole and the equal adhesion in the expansion hole are equipped with amortization fine hair.
As an improvement, the cross section of the frame is U-shaped.
As an improvement, the opening of the silencing hole is in a horn shape.
As an improvement, the plate body is provided with a dust-proof layer matched with the silencing hole.
As an improvement, the silencing hole is hexagonal.
As an improvement, the silencing holes are uniformly arranged.
Compared with the prior art, the utility model has the advantages that: the frame at the edge of the silencer plate body can improve the strength of the silencer plate body; the opening of the silencing hole is in a horn shape, so that more noise can enter the silencing hole; the silencing holes and the expansion holes are internally adhered with silencing fluff, so that fluff entering the silencing holes can be blocked and weakened; the expansion holes can reflect and absorb noise entering the expansion holes so that the noise gradually disappears; the dust-proof layer can block dust raised by air flow, prevent the dust from entering the silencing hole and influence the work of the silencing hole
Drawings
Fig. 1 is a schematic structural view of the present utility model.
Fig. 2 is a schematic structural view of the sound deadening hole of the present utility model.
As shown in the figure: 1. the silencer comprises a silencer body, 2, a frame, 3, a plate body, 4, silencing holes, 5, expansion holes, 6, silencing fluff, 7 and a dustproof layer.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
1-2, a track traffic sound-deadening plate, includes sound-deadening plate body 1 and locates frame 2 at 1 edge of sound-deadening plate body, sound-deadening plate body 1 includes plate body 3 and locates a plurality of amortization hole 4 on the plate body 3, be equipped with in the plate body 3 with the expansion hole 5 of amortization hole 4 intercommunication, equal adhesion in amortization hole 4 and the expansion hole 5 is equipped with amortization fine hair 6.
The cross section of the frame 2 is U-shaped.
The opening of the silencing hole 4 is horn-shaped.
The plate body 3 is provided with a dust-proof layer 7 matched with the silencing hole 4.
The silencing hole 4 is hexagonal.
The silencing holes 4 are uniformly formed.
The working principle of the utility model is as follows: the frame 2 at the edge of the silencer board body 1 can improve the strength of the silencer board body 1; the dust-proof layer 7 can block dust raised by air flow, so that the dust can be prevented from entering the silencing hole 4 to influence the work of the silencing hole 4; the opening of the silencing hole 4 is in a horn shape, so that more noise can enter the silencing hole 4; the silencing holes 4 and the expansion holes 5 are internally adhered with silencing fluff 6, so that fluff entering the silencing holes 4 can be blocked and weakened; the expansion holes 5 can reflect, attenuate and absorb the noise entering the expansion holes, so that the noise gradually disappears.
Finally, it should be noted that: the foregoing description is only illustrative of the preferred embodiments of the present utility model, and although the present utility model has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements or changes may be made without departing from the spirit and principles of the present utility model.
