Noise reduction device for construction sites
The invention relates to the technical field of construction site noise reduction, and specially relates to a noise reduction device for construction sites. The noise reduction device comprises a baffle, a base, a protection device and a box body; the lower end face of the baffle is fixedly connected with the base, the protection device is arranged in the base, the upper end face of the base is fixedly connected with the box body, the outer side of the box body is rotationally connected with a sound absorption device, the inner side of the sound absorption device is provided with a silencing device, and the lower portion of the silencing device is fixedly connected with a sound discharging device. In the noise reduction device, a right sound absorption plate, an upper sound absorption plate, an upper rotating plate, a fixed cylinder, a fixed shaft, a rotating cylinder and a side sound absorption plate are arranged; targeted noise reduction can be carried out on a noise source; the upper sound absorption plate and the side sound absorption plates can shield and absorb noise sources at multiple angles, noise is effectively recycled, vacuum glass plates arranged inside and outside caneffectively prevent noise propagation, and the sound absorption devices arranged in multiple layers can greatly weaken noise and have an excellent noise reduction effect and a very good noise collection function.
本发明涉及工地降噪技术领域，尤其为一种施工场地用降噪装置，包括挡板、底座、防护装置和箱体，所述挡板下端面固定连接有底座，所述底座内部设有防护装置，所述底座上端面固定连接有箱体，所述箱体外侧转动连接有吸音装置，所述吸音装置内侧设有消音装置，所述消音装置下方固定连接有排音装置；本发明中，通过设置的右吸音板、上吸音板、上转动板、固定筒、固定轴、转动筒和侧吸音板，可以针对噪音源进行针对性的降噪，且通过上吸音板和侧吸音板可以对噪音源进行多角度的遮挡吸音，有效的回收噪音，内外设置的真空玻璃板可以有效阻止噪音的传播，而多层设置的吸音装置，可以对极大的削弱噪音，降噪效果极佳具有很好的噪音收集功能。
