Abstract
The utility model discloses a closed sound barrier device with a ventilation function. The device comprises a sound barrier plate (1), and a ventilation sound insulation component (2) comprising a circular mounting base (21) is arranged on the sound barrier plate (1). Mounting plates (22) are arranged on the outer side of the circular mounting base (21) and are connected with the sound barrier plate (1) through connectors. A first metal net (23), a fiber plate (24) and a second metal net (25) are arranged successively in an inner hole of the circular mounting base (21). The fiber plate (24) is clamped and fixed between the first metal net (23) and the second metal net (25). The device has the advantages of being good in sound shielding effect, outstanding in air ventilation, simple in structure and convenient and rapid to mount.
Description
Technical field
The utility model relates to high-speed railway corollary equipment field, is specifically related to a kind of closed sound barrier device with airing function.
Background technology
Be positioned at the section in more several regions of crowd at high-speed railway, often all need to install closed sound barrier device.But, the closed sound barrier device of prior art is in order to realize the isolation of sound, often adopt enclosed structure, cause on the one hand the atmospheric pressure in outside in closed sound barrier device poor larger, easily cause closed sound barrier device structural damage, also can cause on the other hand the air circulation of closed sound barrier device inner side not good.
Utility model content
The technical problems to be solved in the utility model is to provide that a kind of sound shield effectiveness is good, air circulation is good, simple in structure, installation and maintenance are quick.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of closed sound barrier device with airing function, comprise sound shield plates, described sound shield plates is provided with sound insulation assembly, described sound insulation assembly comprises annular mount pad, the outside of described annular mount pad is provided with installing plate, described installing plate is connected with sound shield plates by connector, is provided with the first wire lath, fiberboard and the second wire lath arranged successively in the endoporus of described annular mount pad, and described fiberboard is clamped and fastened between the first wire lath, the second wire lath.
The thickness of described fiberboard is 0.5～2mm.
Described fiberboard is glass wool board or asbestos fiber sheet.
The closed sound barrier device that the utlity model has airing function has following advantage: the utility model is due to the existence of sound insulation assembly, and in the endoporus of annular mount pad, be provided with the first wire lath of arranging successively, fiberboard and the second wire lath, fiberboard is clamped and fastened on the first wire lath, between the second wire lath, because comprising a large amount of fiber mixing, fiberboard is formed by stacking, therefore both can play the effect of shielded sound, guarantee that the closed sound barrier device with airing function can play good sound shield effectiveness, can play again good circulation of air effect simultaneously, prevent from having the closed sound barrier device damage that the closed sound barrier device inner side of airing function and the air pressure difference in outside cause having airing function, guarantee that the closed sound barrier device inner side with airing function has good air quality, there is sound shield effectiveness good, air circulation is good, simple in structure, installation and maintenance are advantage efficiently.

Marginal data: 1, sound shield plates; 2, sound insulation assembly; 21, annular mount pad; 211, endoporus; 212, step; 22, installing plate; 23, the first wire lath; 24, fiberboard; 25, the second wire lath.
The specific embodiment
As depicted in figs. 1 and 2, the closed sound barrier device with airing function of the present embodiment comprises sound shield plates 1, sound shield plates 1 is provided with sound insulation assembly 2, sound insulation assembly 2 comprises annular mount pad 21, the outside of annular mount pad 21 is provided with installing plate 22, installing plate 22 is connected with sound shield plates 1 by connector, in the endoporus 211 of annular mount pad 21, be provided with the first wire lath 23, fiberboard 24 and the second wire lath 25 arranged successively, fiberboard 24 is clamped and fastened between the first wire lath 23, the second wire lath 25.The present embodiment is due to the existence of sound insulation assembly 2, and in the endoporus of annular mount pad 21, be provided with the first wire lath 23 of arranging successively, fiberboard 24 and the second wire lath 25, fiberboard 24 is clamped and fastened on the first wire lath 23, between the second wire lath 25, because comprising a large amount of fiber mixing, fiberboard 24 is formed by stacking, therefore both can play the effect of shielded sound, guarantee that the closed sound barrier device with airing function can play good sound shield effectiveness, can play again good circulation of air effect simultaneously, prevent from having the closed sound barrier device damage that the closed sound barrier device inner side of airing function and the air pressure difference in outside cause having airing function, guarantee that the closed sound barrier device inner side with airing function has good air quality, there is sound shield effectiveness good, air circulation is good, simple in structure, installation and maintenance are advantage efficiently.
In the present embodiment, endoporus 211 places of annular mount pad 21 are provided with step 212, the first wire lath 23, fiberboard 24 and the second wire lath 25 are arranged on step 212 successively, and the second wire lath 25 contacts with step 212, the first wire lath 23 is positioned at outermost, the first wire lath 23 and annular mount pad 21 are by being welded to connect or connector is connected.
The thickness of fiberboard 24 can be selected between 0.5～2mm as required, to guarantee its air permeable effect, can guarantee again the shield effectiveness of sound simultaneously.In the present embodiment, the thickness of fiberboard 24 is specially 1mm.
It should be noted that, fiberboard 24 can adopt glass wool board or asbestos fiber sheet as required, in addition those of ordinary skill in the art obviously can also learn, fiberboard 24 can also adopt other to have similar stable performance, corrosion-resistant, long service life and other fiberboard with low cost as required, and it can realize the effect of sound-proof and ventilating equally.In the present embodiment, fiberboard 24 is glass wool board.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
