Abstract
The utility model discloses an arc type sound absorption screen, and the sound absorption screen existing in the prior art has the problems that the effect of sound absorption is suboptimal, and can be easily damaged by moisture and high temperature, etc. The utility model is characterized in that a micro perforated plate sound absorption structure is composed of a cambered shell and a micro perforated plate which is assembled at the front end face of the shell. The utility model can reduce sounds effectively, has the advantages of landscaping, simple structure, moisture resistance, high temperature resistance, optional purgation and convenient maintenance. The arc type sound absorption screen of the utility model is suitable for overhead roads and industrial and mining establishments.
Description
The utility model relates to a kind of sound absorber, particularly relates to a kind of circular arc type absorbent lined barrier.
When building urban elevated road energetically, sound absorption and insulation device as the supporting facility of road two sides arises at the historic moment, though, occurred some sound absorption and insulation devices at present, still, the sound absorption and insulation effect and the outward appearance of these sound absorption and insulation devices do not reach desirable demand, and, the occasion of using must have certain requirement, therefore, selects different sound absorption and insulation devices to become the problem of current primary thinking.
The purpose of this utility model is that a kind of improved circular arc type absorbent lined barrier will be provided, and it not only can reduce noise effectively, beautify the environment, and simple in structure, moisture resistance is wet high temperature resistant, in addition, is convenient to clean, and maintaining is convenient.
The purpose of this utility model is achieved in that circular arc type absorbent lined barrier of the present utility model has absorbent lined barrier body and base, described absorbent lined barrier body comprises shell and is inlaid in the microperforated panel of shell front end face, the back of the microperforated panel of described shell front end face and described shell are formed with a cavity, described shell is to be circular shape, and the microperforated panel of described shell front end face and the described shell that is circular shape are worked in coordination.
Because the utility model improved existing absorbent lined barrier, designed enclosures is a circular shape, and adopts microperforated panel soundabsorbing construction, makes handsome in appearancely, and acoustically effective is good, scrubs easy to maintenancely, and suitable environment is extensive.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is a circular arc type absorbent lined barrier structural representation of the present utility model.
Fig. 2 is that schematic diagram is looked on Fig. 1 left side.
Below with reference to accompanying drawing the utility model is described in further detail.
With reference to figure Fig. 1 and Fig. 2, circular arc type absorbent lined barrier of the present utility model is made up of the base (2) of absorbent lined barrier body (1) and described absorbent lined barrier body (1) lower end, described absorbent lined barrier body (1) is circular shape, the described absorbent lined barrier body (1) that is circular shape includes shell (3) and microperforated panel (4), described microperforated panel (4) is mounted in the front end face of described shell (3), described microperforated panel (4) cooperatively interacts with the described shell (3) that is circular shape, the back of described microperforated panel (4) and the described shell (3) that is circular shape constitute a cavity, and the cavity of described microperforated panel (4) and described microperforated panel (4) back forms a microperforated panel soundabsorbing construction.
Claims (1)
1. circular arc type absorbent lined barrier, it is made of absorbent lined barrier body (1) and base (2), it is characterized in that described absorbent lined barrier body (1) is formed by shell (3) and the microperforated panel (4) that is assemblied in shell (3) front end face, described shell (3) is circular shape, described microperforated panel (4) matches with the described shell (3) that is circular shape, and the back and the described shell (3) of the microperforated panel (4) of described shell (3) front end face are formed with a cavity.
