The trash rack 622 filters out impurities in water, so that clean water flows through the main pump 61 to prevent damage, the main pump 61 provides power for drainage, and the flap valve assembly 63 plays a role of a one-way valve to prevent reverse flow of water. When the main pump 61 is started, the flap valve assembly 63 has the effect that the pressure exceeds the external water pressure after the pump and then acts, so that the starting of the main pump 61 under pressure is avoided; when the main pump 61 is stopped, the flap valve assembly 63 closes the flow passage in time to prevent the main pump 61 from reversing. When the main pump 61 fails and the flap valve assembly 63 fails and the flow passage cannot be closed, the accident gate 623 immediately drops to cut off the water flow, thereby effectively preventing further expansion of the accident.

as shown in fig. 2, 3 and 4, in the embodiment of the present utility model, the propulsion system 5 is installed in the propulsion flow channel 23 on one side of the station body 2 far from the stern hinge 3, and includes a propeller 51 and a valve 52, which are installed in the station body 2 and near the bow, and aligned with the propulsion flow channel 23, where the propeller 51 adopts a bidirectional blade, and can be pushed forward or backward, so that the station body 2 can be rotated clockwise or counterclockwise, and the valve 52 is connected in series with the propeller 51, so as to seal the propulsion flow channel 23 when the station body 2 is water-blocked;

further, as shown in fig. 11, in comparison with the propulsion system 5 using a propeller 51 and valve 52 structure, in this embodiment, a hoist 8 may be used instead, and in this embodiment, two fixed hoists 8 are respectively disposed on two sides of the river bank, the hoists 8 are horizontally pulled out, and the hoisting head is connected to the bow of the station body 2. When the water channel needs to be closed, the windlass 8 on the opposite side of the gate warehouse acts to pull the station body 2 to the windlass 8 on the same side of the gate warehouse; when a water channel needs to be opened, the windlass 8 on the same bank of the gate warehouse acts to pull the station body 2 to the windlass 8 on the opposite bank of the gate warehouse;

still further, as shown in fig. 12, the hydraulic cylinder 9 is used to replace the propeller 51 and the valve 52, in this embodiment, two sets of hydraulic cylinders 9 are provided on the foundation 1 near the stern hinge 3, the hydraulic cylinders 9 swing greatly in the horizontal position, swing slightly in the vertical position, and the cylinder crane head is connected with the station body 2. When the water channel needs to be closed, one oil cylinder generates pushing force, and the other oil cylinder generates pulling force to push the standing body 2 together; when the water channel needs to be opened, the push-pull of the two oil cylinders is opposite. Compared with the method which only adopts one oil cylinder, the method can avoid the phenomenon that the moment arm is too small at a certain movement position and the movement dead point is difficult to push;

still further, as shown in fig. 13, a propeller 10 that can be extended and contracted up and down is employed. When the design conditions are slightly different, the standing body 2 needs to float higher in the rotation motion, so that the originally designed pushing flow passage is too close to the water surface or even exceeds the water surface, and at the moment, the propeller 51 can hardly generate power. This problem can be solved by using a retractable propeller 51.

Referring to fig. 14, the main pump 61 of the main pump system 6 is not a wet stator full through-flow submersible pump, but a vertical submersible through-flow pump 11 is used, and the design of the main pump runner 22 is slightly different from that of the first embodiment.

Referring to fig. 15, the main pump system 6 does not use a combination of a main pump 61 and a gate assembly 62 with a flap valve assembly 63, but uses a combination of a full-flow pump quick valve 52. The main pump 61 is integrally formed with the valve 52, and is called a pump valve assembly, and serves both functions of draining water and retaining water. Because the gate assembly 62 and the flap assembly 63 are omitted, no accessory is arranged on two sides of the station body 2, the obstruction and disturbance to water flow are reduced, the ship structure 21 is facilitated, and the movement stability is also facilitated.
