Automatically-adjustable noise barrier

Abstract

The invention relates to an automatically adjustable sound insulation barrier, which comprises a fixed barrier part, a liftable barrier part and a control part, the liftable barrier part is movably arranged above the fixed barrier part, and the control part Connect with the liftable barrier part and control the lifting of the liftable barrier part. On the basis of the traditional sound insulation barrier, by dividing the sound insulation barrier into two parts, the liftable barrier can automatically adjust the height of the sound barrier according to the noise level , let it lower the height when the noise is low, so as to increase the visibility of the surrounding residents.

Description

technical field [0001] The invention relates to the field of sound insulation barriers, in particular to an automatic adjustment sound insulation barrier. Background technique [0002] The country has regulations on the noise level of roads, railways, and both sides. For example, it is required that the noise level of the outer edge part critical to both sides of the elevated road should not disturb the residents. Therefore, some equipment in the factory, such as water towers, air-conditioning external units, Fans and other noise control to avoid affecting the environment outside the factory and residents' lives. [0003] Ordinary sound insulation barriers are made of perforated panels or steel plates filled with sound insulation cotton to achieve sound insulation. Because the sound insulation barrier is opaque, it will block the view of surrounding buildings and affect the appearance. On general elevated roads, the traffic flow is heavy and the noise is loud during the ru...
