LYU DEKUN / LYU GUOYUE / LI ZHENGPING / ZHU LEIHONG / QIU ERKANG

The bridge self-cleaning type drainage device comprises a plurality of cleaning rods arranged in a grid plate in a penetrating mode, a connecting rod for connecting the cleaning rods and a driving mechanism for driving the connecting rod to vertically move, and the cleaning rods penetrate through the grid plate and move to the water inlet side of the grid plate; the driving mechanism comprises a support arranged in a bridge drainage channel, a water receiving tank arranged on the support in a sliding mode, a driving elastic piece pushing the water receiving tank to move upwards and a drainage mechanism automatically discharging accumulated water in the water receiving tank, the water receiving tank slides vertically along the support, and the upper end of the water receiving tank is connected with the connecting rod and drives the connecting rod to move vertically. And the drainage mechanism is used for draining accumulated water in the water receiving tank after the water receiving tank moves downwards. When accumulated water falls into the water receiving tank, the water receiving tank gradually descends to drive the cleaning rod to move downwards, then the cleaning rod moves upwards after the accumulated water is discharged out of the water receiving tank, and automatic cleaning of the grid plate is achieved through reciprocating movement of the cleaning rod.

本申请涉及一种用于市政桥梁工程的桥梁自清理式排水装置，其包括穿设于栅格板内的若干清理杆、将清理杆连接的连接杆及带动连接杆竖向移动的驱动机构，清理杆穿过栅格板并移动至栅格板进水一侧，驱动机构包括设置于桥梁排水渠内的支架、滑移设置于支架上的接水槽、推动接水槽向上移动的驱动弹性件及自动排出接水槽内积水的排水机构，接水槽沿支架竖向滑移，接水槽的上端与连接杆连接并带动连接杆竖向移动，排水机构用于将向下移动之后的接水槽内的积水排出。在积水落于接水槽内，接水槽逐步下降从而带动清理杆向下移动，之后在积水从接水槽内排出之后清理杆又向上移动，通过清理杆的往复移动实现对栅格板的自动清理。
