A road and bridge noise reduction device
The invention relates to the technical field of road and bridge noise reduction, and discloses a road and bridge noise reduction device. The device comprises a noise reduction plate, the noise reduction plate is of a hollow cuboid structure, ventilation openings are formed in the front surface and the rear surface of the noise reduction plate, and the front surface and the rear surface of the noise reduction plate are located at the ventilation openings. A plurality of ventilation holes are evenly formed in the lower portion. The inner top of the noise reduction plate is rotationally connected with a wind wheel through a bearing, and a first gear is fixed to the position, located behind the wind wheel, of the outer surface of a middle shaft of the wind wheel. When encountering strong wind or strong wind weather, airflow can blow open elastic valves in the ventilation holes and can push the wind wheel to rotate, under the action of the first gear and a second gear, a first rotating shaft rotates, sound insulation cotton can be rolled to the first rotating shaft, at the moment, the interior of the noise reduction plate is not blocked, through the multiple ventilation holes in the noise reduction plate, wind resistance borne by the noise reduction plate can be reduced, and the situation that the noise reduction plate is blown to be inclined or even blown is avoided.
本发明涉及道路桥梁降噪技术领域，且公开了一种道路桥梁降噪音装置，包括降噪板，所述降噪板为中空的长方体结构，且所述降噪板的前表面和后表面均开设有通风口，所述降噪板的前表面和后表面位于所述通风口。的下方均匀开设有多个通风孔，且所述降噪板的内顶部通过轴承转动连接有风轮，所述风轮中轴的外表面位于所述风轮的后方固定有第一齿轮；当遭遇大风或者强风天气的时候，气流会将通风口中的弹性瓣膜吹开，并可以推动风轮转动，在第一齿轮和第二齿轮的作用下，第一转动转动，可以将隔音棉收卷到第一转轴上，此时降噪板内部没有阻挡，通过降噪板上的多个通风孔可以降低降噪板所受到的风阻，避免降噪板被吹倾斜甚至吹到的情况。
