In addition, a boom cover plate 7 is fixedly installed on the upper portion of the boom 6, the boom cover plate 7 covers the entire width of the gate, and when the gate is in an open state, i.e., the state of fig. 1, the boom cover plate 7 is parallel to the horizontal plane, and water flows over the boom cover plate 7.

The back of the door leaf 5 is a closed cavity, the upper part of the door leaf 5 is provided with a first inlet and outlet port communicated with the closed cavity, the first inlet and outlet port is connected with a gas transmission pipe 12 through a hose 8, and the gas transmission pipe 12 is connected to the output end of an air compressor 14;

besides the cavity which can exchange media with the outside, the door leaf 5 can be provided with a plurality of closed inner cavities, namely the inner cavities are totally closed with the outside, fixed buoyancy is provided for the door leaf in water, so that the adjustable cavity is matched for buoyancy adjustment, the stability of the door leaf 5 during overturning is kept, and the energy consumption of the air compressor is reduced.

In addition, a second inlet and outlet port communicated with the closed cavity is arranged at the bottom of the door leaf 5 and communicated with the water tank 131;

the lower part of the door leaf 5 is provided with a protruding block 51, the protruding block 51 and the limiting block 1 cooperate to limit the water storage limit position when the gate is in a fully closed state, and when the gate is fully closed, as shown in the state of fig. 2, the limiting block 1 blocks the protruding block 51 to move upwards.

The top of the door leaf 5 is provided with a hanging ring 9, and the part of the hanging ring 9 protruding out of the arc surface of the door leaf 5 is in contact with the bottom water stop rubber 2 in the fully opened state of the gate, so as to limit the limit position when the gate is fully opened. When the gate is completely opened, referring to fig. 2, the hanging ring 9 is clamped by the bottom water stop rubber 2 to prevent the gate from continuously descending;

the buoyancy tank 4 can be a hollow tank structure or a solid structure; the buoyancy tank 4 is fixedly arranged at the bottom position of the gate, and referring to fig. 1, in the embodiment, the buoyancy tank 4 is fixedly arranged below the support arm 6;

it should be mentioned that the buoyancy tank 4 is a closed fixed structure, and the buoyancy tank 4 in this embodiment is a fixed buoyancy tank structure, and in practical application, the buoyancy tank can be customized as a standard component, and when being installed on a gate, the installation number of the buoyancy tank can be increased/decreased according to the size and the mass of the gate.

When the gate is in a water storage state, an air inlet switch on the air compressor 14 is closed, so that the air content of the cavity of the gate blade 5 is kept unchanged, and the gate is jacked to the position shown in the figure 2 by means of buoyancy of water in the water tank 131 to the whole gate, so that the closing state of the gate is ensured to be stable;
