The top of the hollow support 15 is rotatably connected with an internal threaded sleeve 17, the internal threaded sleeve 17 is threadedly connected to the screw rod 16, and the lower end of the screw rod 16 is fixedly connected to the gate 3. This structure allows a person to rotate the internal threaded sleeve 17 to drive the screw rod 16 to move up and down, thereby driving the gate 3 to move up and down, and then opening and closing the gate 2.

[0027] refer to Figures 1 to 4 As shown, a rotating handle 18 is fixedly connected to the outer wall of the internal thread sleeve 17 . This structure uses the rotating handle 18 to facilitate personnel to rotate the internal thread sleeve 17 by leveraging force.

[0028] refer to Figures 1 to 4 As shown, guide grooves 19 are provided on the inner walls opposite to each other on both sides of the gate 2, and the two sides of the gate 3 are adapted to slide and plug into the guide grooves 19. This structure utilizes the guide grooves 19 to guide the up and down movement of the gate 3.

[0037] When the water storage volume at the interception point increases due to rain or upstream discharge, the liquid level in the square vertical pipe 6 rises. When the cross-sectional liquid level reaches the liquid level sensor 12, the liquid level sensor 12 will detect the water level and transmit the water level information to the single-chip controller 13. After receiving the signal, the single-chip controller 13 will control the relay 14 to open, thereby powering the water pump 9 to start. At this time, the water at the interception point can be extracted by the water pump 9 and discharged into a safe area through the drain pipe 10, thereby preventing the water from overflowing the gate 2 and affecting the construction, while protecting the safety of the construction personnel.
