Abstract

The invention provides a scouring sluice device comprising a dam foundation, a rubber plate, an air bag and a steel gate; the dam foundation is provided with a groove, and the bottom of the groove isprovided with the air bag; the rubber plate is arranged on the top of the air bag, and the side wall of the rubber plate is in contact with the side wall of the groove; and the steel gate is movably arranged above the rubber plate in the vertical direction. According to the scouring sluice device provided by the invention, sundries in the groove can be removed completely. The gate is closed tightly, and the above rubber plate can play a role in sealing effectively, so that lots of water is saved; and the water-use efficiency of a power station can be improved.

Description

technical field [0001] The invention relates to the technical field of dams, in particular to a sand flushing gate device. Background technique [0002] The sand flushing gate is an independent steel structure hydraulic gate, which uses the power of water flow to flush the sediment deposited in the river to the downstream of the dam. [0003] The bottom of the original sand flushing gate is made of a channel steel door frame. After the sand flushing gate falls, it enters the frame. After falling to the bottom, the sand flushing gate is pressed against the door frame by its own pressure. To the role of water-tight seal. The disadvantage of this method is that the bottom door frame contains sand and gravel. It will fill up the space of the bottom frame, so that when the sand flushing gate falls, it cannot be in place, resulting in a poor seal at the bottom. Due to the high pressure at the bottom, the water leakage will be very serious. Moreover, the sand flushing sluice ge...
