Abstract

The invention discloses a dam gate desilting device, and belongs to the field of hydraulic engineering. The dam gate desilting device comprises a drainage gate arranged on one side of a river channel and used for blocking a diversion canal, and a water taking gate arranged in the river channel and communicated with the diversion canal, and a water taking gallery used for guiding river water to enter the diversion canal is formed in the water taking gate; a sand blocking plate is arranged on the lower side of the water taking gate, the sand blocking plate is arranged on the bottom face of the river channel in a sliding and penetrating mode, and a driving assembly used for driving the sand blocking plate to move in the vertical direction is arranged in the river channel. The dam gate desilting device has the effect of preventing gravels in the river channel from entering the diversion canal.

Description

technical field [0001] The application relates to the field of water conservancy engineering, in particular to a sand discharge device for a dam gate. Background technique [0002] Water conservancy projects refer to projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and rejuvenating profits. In order to draw water from the river to irrigate farmland or drink, people often open diversion canals on one side of the river, and use drainage gates to control the amount of water in the river into the diversion canal, thereby satisfying people's adjustment and distribution of water resources. [0003] In the related art, the Chinese utility model patent whose notification number is CN211143010U discloses a drainage gate, which includes a door frame, a gate, a lifting mechanism and an elastic seal. The inner wall of the door frame is provided with a receiving groove, and the gate is slidably inserted in the receiv...
