Underground-hidden windward silencing device
The invention provides an underground-hidden windward silencing device. The underground-hidden windward silencing device comprises an air inlet cover plate and a silencing cavity located below the airinlet cover plate, the air inlet cover plate is connected with an electric jacking device, the upper surface of the air inlet cover plate is flush with the ground of a silencing chamber, and the lower surface of the air inlet cover plate is connected with a silencing cavity through a first flange and a connecting pipeline; and the connecting pipeline is located in the silencing cavity, and silencing holes are formed in the inner wall of the silencing cavity. The underground-hidden windward silencing device is located below the ground of the silencing chamber, the space in the silencing chamber cannot be occupied, meanwhile, silencing improvement is made on the air inlet cover plate and the interior of the silencing cavity, and the whole silencing device is simple in structure and good insilencing effect.
一种地藏式迎风消音装置，包括进风口盖板和位于进风口盖板下方的消音腔，所述的进风口盖板与电动顶升装置相连，进风口盖板的上表面与消音室地面相平齐，进风口盖板的下表面通过第一法兰和连接管道与消音腔相连，连接管道位于消音腔内，所述的消音腔内壁设有消音孔。本发明位于消音室地面的下方，不会占用消音室内的空间，同时本发明在进风口盖板处和消音腔内分别做了消音改进，整个消音装置结构简单，消音效果好。
