Description

Gate sealing device for hydraulic engineering Technical Field The utility model relates to the technical field of hydraulic engineering, in particular to a gate sealing device for hydraulic engineering. Background The gate in hydraulic engineering is a key device for controlling water flow and regulating water level, and is widely applied to facilities such as reservoirs, dams, ship locks, irrigation systems and the like. The gate is opened or closed to regulate water flow, prevent water level from being too high or too low, and ensure safety of downstream areas. Common types of gates include hinged gates, sliding gates, lifting gates, and the like. The sealing performance, the structural strength and the corrosion resistance are important consideration factors in design and use, normal operation and flood control safety of hydraulic engineering are ensured, and in order to ensure full utilization of water resources, the sealing performance requirement on a gate is high, so that the gate sealing device for the hydraulic engineering is required. Through retrieval, chinese patent 'an authorized bulletin number' CN221972275U 'of a hydraulic engineering opening and closing gate', through the cooperation of a sealing groove, a reset cavity, a guide rod, a sliding block, a sliding hole, a spring, a limiting plate and a positioning plate, when a gate plate is opened, the spring rebounds to push the sliding block to rise and then seal the sealing groove, so that sediment can be effectively prevented from sinking into the sealing groove to influence the sealing performance of the subsequent gate plate closing after the gate plate is opened, and the sealing performance after the gate plate is closed is improved; the above-mentioned application is through cooperation rivers avoiding silt to sink into the recess when the spring cooperation slider makes the flashboard open, has improved the leakproofness when the flashboard is closed, but when the flashboard is closed, usually is the flood discharge and ends, and rivers are less, and sediment such as silt can gather near the slider simultaneously, can't be cleared up by rivers, and when closing the gate this moment, there is the gap probably to lead to the gate below, leads to the gate leakproofness to reduce.
