The invention relates to an impulse type hydraulic self-cleaning rainwater pipe gallery and a hydraulic self-cleaning device thereof, and belongs to the field of rainwater pipe galleries. The hydraulic self-cleaning device comprises a rotating shaft and a bucket-shaped gate rotationally connected with the rotating shaft; the bucket-shaped gate is provided with an upstream side and a downstream side, a water containing cavity with an open upper end is formed between the upstream side and the downstream side, and balance holes communicating with the water containing cavity are formed in the upstream side; the bucket-shaped gate is of an eccentric structure and can be closed by means of self-weight, and when water in the water containing cavity reaches a certain liquid level, the bucket-shaped gate is opened under the acting force of the water in the water containing cavity; the rotating shaft is arranged on the inner wall of a pipe gallery body, the upstream side of the bucket-shaped gate is located upstream in the water flow direction, and the downstream side is located downstream in the water flow direction; and water flow is cut off when the bucket-shaped gate is closed, and impulse type water flow is formed at the bottom of the pipe gallery body when the bucket-shaped gate is opened. Silt in the rainwater pipe gallery is taken away through the impulse type water flow, so thatimpulse type hydraulic self-cleaning of the rainwater pipe gallery is achieved, and the silt deposition problem of the rainwater pipe gallery is solved.
本发明涉及一种脉冲式水力自清洗雨水管廊及其水力自清洗装置，属于雨水管廊领域。水力自清洗装置包括转轴和与转轴转动连接的斗状闸门；斗状闸门具有迎水侧和背水侧，迎水侧和背水侧之间形成上端开放的容水腔，迎水侧设有与容水腔贯通的平衡孔；斗状闸门为偏心结构，能依靠自重而关闭，并且当容水腔内的水达到一定液位时，受容水腔内水的作用力而打开。转轴安装在管廊本体的内壁上，斗状闸门的迎水侧位于水流方向的上游，背水侧位于水流方向的下游；斗状闸门关闭状态下截断水流，打开状态下在管廊本体的底部形成脉冲式水流。利用脉冲式水流将雨水管廊内的泥沙带走，实现雨水管廊的脉冲式水力自清洗，解决雨水管廊泥沙淤积问题。
