Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of water conservancy and hydropower engineering, especially to a water lock gate opening and closing shunt water diversion device for water conservancy and hydropower engineering. BACKGROUND

[0002] A low-head hydraulic structure built on a river channel or a channel to control flow and regulate water level by using a gate. Closing the gate can block floods, tides or raise the upstream water level to meet the needs of irrigation, power generation, shipping, aquaculture, environmental protection, industrial and domestic water, etc. Opening the gate can release floodwater, stagnant water, abandoned water or waste water, and also can supply water to the downstream river channel or channel. In water conservancy engineering, the water lock is widely used as a building for retaining, discharging or taking water. When the gate is closed, the gate chamber will bear the horizontal thrust generated by the difference between the upstream and downstream water levels, which may cause the gate chamber to slide downstream. Therefore, when the gate is opened, it is necessary to shunt water diversion to reduce the water pressure difference and relieve the impact force.

[0003] However, the existing water lock gate opening and closing shunt water diversion device cannot achieve the purpose of reducing the water pressure difference, and the efficiency of shunt water diversion is low. The water inlet aperture is small, and there are many suspended garbage in the gate channel. When shunting, the garbage will flow to the water inlet. Large-size garbage cannot pass through the water inlet quickly and will block the water inlet. Therefore, the present application provides a water lock gate opening and closing shunt water diversion device for water conservancy and hydropower engineering to meet the needs. SUMMARY
