DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0016] Please refer to Figures 1-4 , a self-cleaning water discharge culvert gate, including a culvert 1 arranged in a dam body 9, wing walls 2 are respectively arranged at both ends of the culvert 1, a gate 3 is arranged on one of the wing walls 2, a bottom plate 10 is arranged below the gate 3, a wire winding device 4 is arranged at the top of the wing wall 2 on the side away from the gate 3, a cleaning block 8 is arranged in the culvert 1, the two ends of the cleaning block 8 are respectively connected to a forward pulling rope 5 and a reverse pulling rope 6, the reverse pulling rope 6 passes through a rope loop 7 arranged on the inner wall of the culvert 1 and then passes back through the cleaning block 8, the forward pulling rope 5 and the reverse pulling rope 6 are respectively wound by the wire winding device 4. When the wire winding device 4 winds the forward pulling rope 5, the forward pulling rope 5 drives the cleaning block 8 to move forward, and the cleaning block 8 cleans out the blockage in the culvert 1. When the wire winding device 4 winds the reverse pulling rope 6, the cleaning block 8 moves backward and returns to its original position.

[0017] The cleaning block 8 is an annular airbag, and the airbag can be inflated and deflated. When the airbag is inflated, it can fill the inner wall of the culvert 1, so that the airbag can carry out the garbage in the culvert 1. After the airbag is deflated, it is pulled back by the reverse pull rope 6 for the next use.

[0018] The wire winding device 4 includes a base 41 fixed on the top of the wing wall 2. A motor 42 is fixedly installed on the top of the base 41. The driving end of the motor 42 is connected to a rotating shaft 43. A forward pull rope winding module 45 and a reverse pull rope winding module 46 are slidably installed on the base 41. The rotating shaft 43 separately drives the forward pull rope winding module 45 and the reverse pull rope winding module 46 to wind. The forward pull rope winding module 45 winds the forward pull rope 5, and the reverse pull rope winding module 46 winds the reverse pull rope 6.

[0019] Specifically, both the forward pull rope winding module 45 and the reverse pull rope winding module 46 include a frame slidably installed on the base 41. A winding roller is rotatably installed in the frame. The winding roller is of a cylindrical structure and a keyway is provided on the inner wall. Two flat keys 44 corresponding to the keyway are provided on the rotating shaft 43. The forward pull rope 5 and the reverse pull rope 6 are respectively wound around the two winding rollers. When using the forward pull rope winding module 45, move it to connect it to the rotating shaft 43, and drive it through the motor 42 to drive the forward pull rope 5 to wind. When using the reverse pull rope winding module 46, disconnect the connection between the forward pull rope winding module 45 and the rotating shaft 43, connect the reverse pull rope winding module 46 to the rotating shaft 43, and drive it through the motor 42 to drive the reverse pull rope 6 to wind.

[0020] The motor 42 is a servo motor, and the servo motor is convenient for precise control through a servo controller.
