Urban drainage system
The invention belongs to the technical field of urban drainage, and particularly relates to an urban drainage system. The urban drainage system comprises a cylindrical door body, one side of the doorbody is fixedly connected with a flange plate, the other side of the door body is provided with an oblique contact face, and a rubber sealing ring is mounted on the contact face; a door cover is hinged to the top of the door body through a support, and the door cover is used for sealing the door body; a set of sliding holes is formed in the contact face, pistons are connected into the sliding holes in a sliding sealing mode, the sides, close to the contact face, of the pistons are fixedly connected with jacked rods, and the jacked rods extend outside the door body; a set of damping holes is circumferentially and evenly distributed on each piston, and springs are fixedly connected between the pistons and the bottoms of the sliding holes; and the pistons are soaked in hydraulic oil in the sliding holes. The jacked rods are jacked through the door cover, the rotating speed of the door cover is decreased, and rigid impact of the door body is reduced; and abrasion of a sealing ring is reduced, and thus airtightness of the door cover and the door body is improved.
本发明属于城市排水技术领域，具体的说是一种城市排水系统，包括圆筒形的门体；门体一侧固连有法兰盘，门体另一侧设有倾斜的接触面，接触面上安装有橡胶密封圈；门体顶部通过支架铰接有门盖，门盖用于对门体进行密封；接触面上开设有一组滑孔，滑孔中滑动密封连接有活塞，活塞靠近接触面的一侧固连有顶杆，顶杆延伸至门体外部；活塞上圆周均布有一组阻尼孔，活塞与滑孔底部之间固连有弹簧；活塞浸泡在滑孔中的液压油中；本发明通过门盖顶动顶杆，降低门盖的转动速度，减少门体的刚性撞击；减少密封圈的磨损，进而增加门盖与门体的密封性。
