Easy-to-maintain ventilation type sound barrier
The invention relates to an easy-to-maintain ventilation type sound barrier. The sound barrier comprises a composite ventilation unit plate and a top end noise reduction plate arranged at the top endof the composite ventilation unit plate, the composite ventilation unit plate comprises a metal framework, a movable noise reduction plate, an embedded noise reduction plate and a transparent plate, and the movable noise reduction plate, the embedded noise reduction plate and the transparent plate are installed on the metal framework; shutter holes are formed in the surfaces, facing the sound source direction, of the movable noise reduction plate and the embedded noise reduction plate, and the surface, facing the sound source direction, of the top end noise reduction plate is subjected to galling treatment. According to the main principle of ventilation, a rotating shaft of the movable noise reduction plate is eccentrically arranged, unbalance loading can be generated under the action of cross wind, the noise reduction plate rotates around the shaft, when the wind area and weight of the noise reduction plate are fixed, the deflection angle of the noise reduction plate can be changed along with the change of the wind speed, a ventilation unloading channel can be opened to different degrees, and the purpose of ventilation unloading is achieved. In addition, both the movable noise reduction plate and the embedded noise reduction plate can be detached from the sound barrier, and the purpose of easy maintenance is achieved.
本发明涉一种易维修通风型声屏障，包括复合通风单元板和设置在复合通风单元板顶端的顶端降噪板，其中，所述复合通风单元板包含金属骨架和安装在所述金属骨架上的活动式降噪板、嵌入式降噪板及透明板；所述活动式降噪板、嵌入式降噪板面向声源方向的表面设置有百叶孔，所述顶端降噪板面向声源方向的表面经过拉毛处理。通风的主要原理是：活动式降噪板的转轴偏心设置，在横风作用下，会产生偏载，使降噪板绕轴转动，当降噪板的受风面积和重量一定时，降噪板的偏转角度会随着风速的改变而改变，使通风卸载通道会不同程度的开启，实现通风卸载的目的。此外，活动式降噪板和嵌入式降噪板均可从该声屏障上拆卸下来，实现了易维修的目的。
