[0002] The flap gate is an energy-saving and environmentally friendly gate. It is now widely used in various water conservancy projects. It is mainly used to intercept or discharge water in reservoirs, rivers, reservoirs, etc., and can effectively control the water level. This requires improving the sealing of the flap gate. Nowadays, the side leakage prevention method of the flap gate mostly uses water stop strips for sealing, but there is only one barrier, the water stop strip. If the water stop strip is aged or falls off due to long-term erosion by water flow, it will directly cause the gate to leak, posing a safety hazard. Moreover, if too many anti-leakage equipment is added, the burden on the gate door panel will be increased, reducing the service life of the gate.
