Acoustic noise reduction device in rail transit tunnel
The invention discloses an acoustic noise reduction device in a rail transit tunnel in the technical field of railways, which comprises a controller and a tunnel side wall, a humidity detector and a perforated aluminum plate are mounted on the tunnel side wall, and the humidity detector is electrically connected with the controller; an enameled steel plate is mounted on one side, away from the tunnel side wall, of the perforated aluminum plate; a plurality of driving assemblies and noise reduction assemblies are arranged on the enameled steel plate; the driving assembly is used for driving the noise reduction assembly to contract and unfold according to the air humidity; the retractable and expandable noise reduction assembly is adopted, according to the humidity of the environment where the noise reduction assembly is located, the hexagonal sound absorption barrel deforms and shrinks, the contact area between the hexagonal sound absorption barrel and air becomes small, and therefore the moisture absorption degree of the hexagonal sound absorption barrel is reduced; in the deformation and contraction process of the hexagonal sound absorption barrels, dust attached to the hexagonal sound absorption barrels can be shaken off; therefore, the purpose of maintaining the noise reduction assembly is achieved.
本发明公开了铁路技术领域的一种轨道交通隧道内声学降噪装置，包括控制器和隧道侧墙，隧道侧墙上安装有湿度检测器和穿孔铝板，湿度检测器与控制器电连接；穿孔铝板远离隧道侧墙的一侧安装有搪瓷钢板；搪瓷钢板上设有若干驱动组件和降噪组件；驱动组件用于根据空气潮湿度带动降噪组件收缩和展开；采用可收缩和展开的降噪组件，根据降噪组件所处环境的潮湿度，使六边形吸声筒发生形变收缩，使其与空气的接触面积变小，从而降低六边形吸声筒的吸湿程度；在六边形吸声筒形变收缩的过程中，还可将附着在六边形吸声筒上的灰尘抖落；从而达到对降噪组件的维护目的。
