The dam is a flood discharging device, is a water retaining building for intercepting a river channel and a river so as to raise the water level or regulate the flow, is usually built together with a reservoir, and has the advantages of flood control, water supply, irrigation, hydroelectric power generation and the like. In the flood season of China, especially in the typhoon season in summer, the water level in the river reservoir rises rapidly, and at the moment, the flood discharge needs to be carried out by opening the floodgate through the dam.
However, the gate of some small-size hydraulic and hydroelectric engineering dams opens slowly, and when the gate is opened, the atress is great in gate bottom, receives the damage easily to need manual control to adjust the water level, it is very inconvenient to use. Moreover, when the gate is opened to discharge floodwater, if more sediment is in the river course, the bottom of the gate can be piled up some sediment in the flowing process, and the sediment stays under the gate and is inconvenient to clean, when the gate is finished to discharge floodwater and needs to be put down again to close the flood discharge port, the bottom of the gate can not be completely jointed with the bottom of the river course due to sediment accumulation at the bottom, so that the closing tightness of the gate can be influenced. Meanwhile, sundries in the river channel can easily enter the inside of the water outlet, so that the inside of the water outlet is blocked. Therefore, we propose a new flood discharge device for hydraulic and hydroelectric engineering.
