The spring 34 is sleeved on the screw 33, one end of the spring 34 abuts against the support plate 31, and the other end abuts against the limit block 32. To prevent the nut from loosening, an elastic washer 35 is provided between the nut and the support plate 31. The contact surface of the limiting block 32 and the gate 2 is set to be an inclined surface, so that the surface of the gate 2 can be better attached, and the limiting effect is better; when the shutter 2 abuts on the stopper 32, the spring 34 not only restricts the opening/closing angle of the shutter 2 but also buffers the shutter 2.
In order to control the installation height of the gate 2 and the ground so as to prevent sundries from influencing the opening and closing of the gate 2, a rectangular distance limiting rod 6 is vertically fixed on the bottom side surface of the door pocket 1. In order to increase the tightness between the door pocket 2 and the gate 2, a sealing ring 7 is arranged on the end face of the door pocket 1 contacted with the gate 2, and the sealing ring 7 is fixed on the outer edge of the inner side face of the gate 2. In order to facilitate the operator to open the gate 2 to clean the drain pipe 11, a handle 8 is arranged on one side of the gate 2, which is far away from the rotating shaft 5.
The implementation principle of the embodiment of the application is as follows: when the gate 2 is impacted by water flow in the drain pipe 11, the gate 2 is opened to abut against the surface of the gate 2, and the maximum opening and closing angle of the gate 2 is limited by the limiting block 32; when there is no water flow in the drain pipe 11, the gate 2 is automatically closed by the horizontal component of its own weight.
