In order to solve the problem that the leakage stoppage control of hydropower station gates cannot effectively meet the needs of water supply and flood discharge, and timely control the operation status of the gates, a jet type leakage stoppage technology and experimental research for hydropower station gates were proposed. The gate leaf, support hinge, support arm, top section gate and other components shall be hoisted by hoisting method; Based on the actual operation and characteristics of the hydropower station, it determines the influencing parameters of the hydropower station gate; Using displacement sensors and control boxes, real-time control of hydropower station gates is completed. Based on the obtained layout scale of the hydropower station, the flow distribution points of the hydropower station are determined. Based on this, the closure planning scheme for hydropower stations is determined based on the flow coverage of each hydropower station, and a gate jet closure planning model for hydropower stations is constructed. By using the combination set of closed planning paths for hydropower stations, a weight set for closed planning of hydropower stations is constructed. The comprehensive weight value of closed planning is represented by the feature correlation matrix, and the design of gate jet sealing technology for hydropower stations is achieved. The experimental study shows that the proposed technology has a low water leakage rate for plugging; The plugging effect is good, and the amount of leakage after the application of this technology is lower than before.
