Abstract:
A soundproof door system for improving the quality of an acoustic environment at the boundary of a power facility. The soundproof door system comprises a door body main structure, a movable deep groove cover plate, and a double-layer wall, wherein the door body main structure is arranged in an underground deep groove. The inner and outer sides of the lower portion of the door body main structure are respectively provided with rubber soundproof structures for ensuring soundproof and sealing effects, and the rubber soundproof structures, the outer surface of the door body main structure and the inner surface of the deep groove form a sound elimination cavity; and the frequency of sound elimination of the formed sound elimination cavity can be regulated and controlled by adjusting the depth of the deep groove and the relative distance between the outer surface of the door body main structure and the inner surface of the deep groove, and thus noise of a specific frequency is eliminated. The movable deep groove cover plate is arranged at one end of the door body main structure, and the upper surface of the movable deep groove cover plate is flush with the surface of the ground; and when the door body main structure is opened, the deep groove is covered so as to ensure that a vehicle passes smoothly. The double-layer wall is constructed at two ends of the door body main structure. The soundproof door system provides a systematic solution, and has a wider application range, a better soundproof effect and lower maintenance costs.
