Abstract

The invention discloses a noise reduction protection device of a road and bridge, and relates to the technical field of noise reduction equipment. The noise reduction protection device comprises noisereduction plate assemblies, a sound refraction plate assembly, a fence mounting seat, a buffering and anti-collision fence, linkage mechanisms and refraction plate clamping mechanisms. The noise reduction protection device has the beneficial technical effects that the device as the anti-collision and buffering functions; the device is further provided with two layers of noise reduction plates, anarc moving refraction plate can slide upwards and be converged towards the inner side of the bridge by a certain radian, and therefore noise within a wider range is stored within a relatively narrowrange and is absorbed and weakened, and the function of reducing noise of the road and bridge is achieved better. The sound refraction plate assembly is connected to the front ends of the noise reduction plate assemblies in a sliding fit manner, the fence mounting seat is fixedly connected to the front end of the sound refraction plate assembly, the buffering and anti-collision fence is connectedto the fence mounting seat in a sliding fit manner, the number of the linkage mechanisms is four, the four linkage mechanisms are arranged at the four corners of the buffering and anti-collision fence, and the four linkage mechanisms are connected to the fence mounting seat.
