Road and bridge noise reduction device and noise reduction method
The invention discloses a road bridge noise reduction device and a noise reduction method, and belongs to the field of road bridge noise reduction, the road bridge noise reduction device comprises a sound insulation plate, and further comprises a sound moving mechanism, and the sound moving mechanism is installed on the right front side wall of the sound insulation plate and driven by noise generated by a road bridge; an air and water spraying mechanism; an anti-collision protection mechanism; and a ventilation mechanism. On one hand, dust falling is conducted on the external environment, meanwhile, sprayed water can absorb generated noise, the pavement of a road bridge can be cooled, and therefore noise is reduced, on the other hand, dust on the surface of the sound absorption board can be removed, the sound absorption performance of the sound absorption board can be recovered, the gas pressure in the sound absorption board can be changed, and noise is reduced. The sound absorption performance is adjusted, the expected sound absorption effect is achieved, moisture on the surface and in the sound absorption board can be helped to evaporate, moisture is prevented, the sound absorption performance is kept stable, meanwhile, the humidity in the sound absorption board can be reduced, bacterium breeding is prevented, and the service life of the sound absorption board is prolonged.
本发明公开了一种道路桥梁降噪装置及降噪方法，属于道路桥梁降噪领域，一种道路桥梁降噪装置，包括隔音板，还包括：音动机构，音动机构安装在隔音板的正前方侧壁上，由道路桥梁产生的噪音所驱动；喷气喷水机构；防撞保护机构；换气机构。本发明一方面对外界环境进行降尘，同时喷出的水能够吸收产生的噪音，并且能够对道路桥梁的路面进行降温，从而减少噪音的产生，另一方面能够清除吸音板表面的灰尘，恢复其吸音性能，并且可以改变吸音板内部的气体压强，从而调整吸音性能，使其达到预期的吸音效果，还可以帮助吸音板表面和内部的水分蒸发，防止潮湿，保持吸音性能稳定，同时能够降低吸音板内部的湿度，防止细菌滋生，延长吸音板的使用寿命。
