Sound barrier device for preventing noise pollution

Abstract

The invention discloses asound barrier devicefor preventing noise pollution. The device structurally comprises a mounting seat, a fixing clamp, a sound insulation screen and a placement box are arranged on the mounting seat, and the fixing clamp is fixedly connected with the right side of the upper surface of the mounting seat through a screw; the sound insulation screen is fixedly connected with the middle of the upper surface of the mounting seat through screws, and the placement box is fixedly connected with the left side of the upper surface of the mounting base through screws; a ventilation pipe is arranged on the fixing clamp, a guide pipe and through holes are arranged on / in the ventilation pipe, the guide pipe is in sealed connection with the side face of the ventilation pipe through screws, and the through holes are evenly distributed in the right side of the ventilation pipe; and the sound insulation screen comprises a blind window, a through groove, a first noise elimination layer, a second noise elimination layer and a third noise elimination layer. According to the sound barrier device, automobile tail gas treatment is achieved, pollution of the automobile tail gas to the environment is reduced, and the environment protection effect in the using process of the sound barrier device is improved.

Description

technical field [0001] The invention relates to the technical field of preventing and controlling noise pollution, in particular to a sound barrier device for preventing and controlling noise pollution. Background technique [0002] The noise generated during the operation of high-speed railways and road vehicles or equipment will cause relatively large noise pollution to residents, schools and office areas along the road and nearby. Recently, sound barriers are mainly used to block the transmission of noise, so as to achieve the purpose of preventing and controlling noise pollution. [0003] At present, the existing sound barrier devices for the prevention and control of noise pollution still have some deficiencies, for example; The protective effect of the environment during the use of the sound barrier device is improved, and the existing sound barrier device for the prevention and control of noise pollution cannot heat the road surface in cold weather, and the road surf...
