[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1. In the utility model, by setting a cleaning device, when the gate body needs to be opened, the cylinder is first started, and the cylinder starts to drive the gate body to move upward inside the vertical groove. The gate body moves upward to complete the opening operation of the gate body. At this time, the mud and sand in the water are easy to accumulate on the bottom wall surface of the door frame. At this time, the motor can be started, and the motor starts to drive the first threaded rod to rotate. The rotation of the first threaded rod drives the horizontal strip to move inside the slide groove. The movement of the horizontal strip inside the slide groove drives the support rod to move. The movement of the support rod drives the U-shaped tube to move. The movement of the U-shaped tube drives the connecting rod to move. The connecting pipe moves, and at the same time, the U-shaped pipe and the connecting pipe move to drive the nozzle to move. When the nozzle moves to a position that passes through the first through hole and moves to a suitable position, the air pump is started. The air pump can transport gas to the inside of the U-shaped pipe through the suction pipe and the drainage pipe. The gas inside the U-shaped pipe is transported into the inside of the connecting pipe and is finally discharged from the nozzle. Then, the sludge and debris on the bottom wall of the door frame are washed away by the airflow and the generated bubbles. Through the cooperation of the above structure, it is avoided that when the gate body contacts the bottom wall of the door frame, the sludge and debris cause the bottom of the gate body to tilt and affect the flow-blocking effect.

[0013] 2. In the utility model, by setting a protective device, when it is necessary to protect the cylinder, the rotating wheel is first rotated, and the rotation of the rotating wheel drives the second threaded rod to rotate. Since the threads on the surface of the second threaded rod are reverse threads with the rotating wheel as the center, when the rotating wheel drives the second threaded rod to rotate, the two movable plates threadedly connected on its surface will move in the direction away from each other inside the groove, and the two movable plates move in the direction away from each other inside the groove, driving the hinged plate to move, and the movement of the hinged plate pulls the extension plate to move downward, and the downward movement of the extension plate drives the protective cover to move downward, and the downward movement of the protective cover drives the slide plate to move downward on the surface of the vertical rod. At the same time, when the protective cover moves downward to the position that covers the cylinder inside it, the rotation of the rotating wheel can be stopped. Through the cooperation of the above-mentioned structure, the protective cover can protect the cylinder to prevent the cylinder from being corroded and damaged after long-term wind and sun exposure.
