A composite mobile sound barrier baffle with self-cleaning function and its components

Abstract

The invention discloses a compound movable sound barrier board with a self-cleaning function and an assembly thereof and belongs to the technical field of sound absorbing barriers. The compound movable sound barrier board primarily comprises a mounting main body, a main sound barrier board, a mounting fixed plate, an auxiliary sound barrier plate, a sound isolating board, winding buffer plates, amoving assembly and a cleaning assembly. The sound barrier demands in fence areas in different size ranges are met by means of the auxiliary sound barrier plate, and adjacent two sub auxiliary barrierplates can be folded to each other, so that the compound movable sound barrier board is convenient to move. Noises are lost between a wavy sound isolating layer and a built-in sound isolating layer as much as possible through the sound isolating board, so that pollution of the noises to an external environment is reduced; by arranging the winding buffer plates, diffraction of sound waves from thetop end is reduced while sound waves are absorbed well, so that the sound isolating effect is improved. The compound movable sound barrier board has the advantages of being convenient to move, good in sound isolating effect and convenient to clean, and is suitable for being popularized massively.

Description

technical field [0001] The invention belongs to the technical field of sound-absorbing barriers, and in particular relates to a composite mobile sound barrier plate with self-cleaning function and its components. Background technique [0002] The sound insulation barrier is a sound insulation facility. In order to block the direct sound between the sound source and the receiver, a facility is inserted between the sound source and the receiver, so that the sound wave propagation has a significant additional attenuation, thereby weakening the sound of the receiver. Noise impact in a certain area. Sound insulation barriers are mainly used outdoors. With the increasing noise pollution of road traffic, some countries use a large number of various forms of barriers to reduce traffic noise. In buildings, if the requirements for sound insulation are not high, barriers can also be used to reduce traffic noise. To separate the workshop and the office, the barrier can be easily disass...

AI Technical Summary

Problems solved by technology

[0004] The existing sound insulation barriers only absorb and weaken the direct sound waves, but cannot deal with some of the noise sound waves diffracted by the upper end of the sound insulation barriers, which results in poor sound insulation effects of the barriers and the noise that cannot be blocked as required The size of the source area adjusts the number of sound insulation barriers. When it needs to be transported, the sound insulation barriers cannot be folded, which will easily cause inconvenience in movement
