[0002] A reservoir generally consists of a water retaining structure, a water conveyance structure, and a water discharge structure. Among them, a water control gate is usually arranged in the water discharge structure. By closing the water control gate, flood can be intercepted, tides can be blocked, or the upstream water level can be raised to meet the needs of irrigation, power generation, shipping, aquaculture, environmental protection, industrial and domestic water use, etc.; by opening the water control gate, flood water, waterlogging water, waste water or waste can be discharged, and water can also be supplied to the downstream river or channel. In water conservancy projects, water control gates, as structures for retaining water, discharging water or taking water, are widely used. In conventional technology, a single gate is used for interception in the water control gate, and an additional filter screen is used for filtration to improve the quality of the water discharged from the reservoir.
