[0002] The gate is a control facility used to close and open the discharge (release) channel. It is an important part of water conservancy buildings and can be used to intercept water flow, control water level, adjust flow, discharge sediment and floating objects, etc. The application number CN202223420582.8 is retrieved. It is a water conservancy gate. The utility model can directly collect the floating objects filtered in the filter basket, remove the filter net from the left and right gate piers, and directly pull it away for cleaning. The staff does not need to use other salvage tools, which saves manpower and time and improves the cleaning efficiency.
