[0024] like Figs. 1-3 As shown in the figure, the present embodiment proposes a flip-fold gate for river management, which includes a pipe body 1, a gate plate 2, a fixing component and a winch device.

[0025] The upper end of the pipe body 1 is provided with a frame 3; an L-shaped plate 4 is connected to the gate 2, and a rotating seat 8 is installed on the frame 3. The L-shaped plate 4 is rotatably installed on the rotating seat 8; a first limiting seat 91 is installed on the frame 3. When the gate 2 rotates downward to the bottom position, the L-shaped plate 4 contacts the first limiting seat 91. The first limiting seat 91 can support the L-shaped plate 4, thereby reducing the load on the rotating shaft of the L-shaped plate 4; a sealing mechanism is installed on the side of the gate 2.

One end of the high-strength steel wire rope 10 is fixedly wound on the winding reel 7, and the other end is connected to the limit rod 12. A second limit seat 92 is installed on the frame 3. The second limit seat 92 is set to limit the rotation angle of the gate plate 2, so that the angle between the gate plate 2 and the upper surface of the frame 3 is less than 90 degrees.

[0028] Specifically, the winch device is arranged to realize the winding and unwinding of the high-strength steel wire rope 10, so as to drive the limiting rod 12 to rotate around the rotating shaft of the L-shaped plate 4, and the limiting rod 12 drives the gate plate 2 to rotate in the movement process, thereby realizing the opening and closing function of the pipeline body 1; the sealing mechanism is arranged on the side surface of the gate plate 2, and the sealing mechanism does not have large friction during the sealing process, thereby prolonging the service life of the sealing mechanism; when the pipeline body 1 is sealed, the high-strength steel wire rope 10 is unwound, and when the gate plate 2 completely blocks the side opening of the pipeline body 1, the high-strength steel wire rope 10 is continuously unwound, so that the high-strength steel wire rope 10 is in a relaxed state, at this time, the limiting rod 12 moves downward due to the action of gravity, so that the bottom end of the limiting rod 12 is inserted into the limiting hole 131, thereby completing the limiting work of the gate plate 2, preventing the gate plate 2 from being slightly displaced due to water flow impact, improving the sealing property between the gate plate 2 and the pipeline body 1, and having the advantages of simple structure and good sealing effect; and since the sealing mechanism is arranged on the side surface of the gate plate 2, the sealing mechanism can be replaced after the gate plate 2 is driven to overturn upward.
