[0021] The inside of the water inlet pipe 11 is rotationally provided with a flap 18, the front side of the flap 18 is provided with a mounting hole, a rotating shaft 19 is rotationally arranged in the mounting hole, a torsional spring 2 is fixedly arranged between the rotating shaft 19 and the mounting hole, a guide plate 17 is fixedly arranged on the left side of the inner side wall of the water inlet pipe 11, the top of the flap 18 is attached to the bottom of the guide plate 17, the guide plate 17 is located above the torsional spring 2, the guide plate 17 is located below and left of the collecting hopper 14, the rotating shaft 19 is fixedly arranged inside the water inlet pipe 11, the upward turning angle of the flap 18 is limited by the guide plate 17, and the sewage flowing out of the drain hole of the collecting hopper 14 can be guided to the right side of the flap 18 through the guide plate 17, so that the sewage can more easily overcome the elastic force of the torsional spring 2 to drive the flap 18 to turn downward, so that the sewage can flow downward into the drainage pipe network 1, when the top of the flap 18 is not covered with sewage, the flap 18 is driven to move upward and reset by the elastic force of the torsional spring 2, and the water inlet pipe 11 is closed, so that the upward reverse stringing of the sewage odor in the drainage pipe network 1 can be reduced to affect the urban air quality, and the flap 18 corresponds to the collecting hopper 14.

[0022] Working principle: the drainage pipe network 1 is buried in the city below the road surface, then the inlet pipe 11 is fixed in the city drainage well, and the top of the support frame 12 is flush with the city road surface, so as to complete the installation of the device. The anti-falling rod 13 can prevent pedestrians from falling into the inlet pipe 11. When the sewage carrying fallen leaves and garbage enters the inlet pipe 11, the circular arc design on the surface of the anti-falling rod 13 can reduce the contact friction between the fallen leaves and garbage and the anti-falling rod 13, so that the fallen leaves and garbage carried by the sewage can smoothly fall into the inlet pipe 11 through the gap between the anti-falling rod 13 and the support frame 12, thereby preventing the fallen leaves and garbage from blocking above the anti-falling rod 13 and the support frame 12. The screw rod 15 is screwed with the nut 16 through the through hole of the collecting hopper 14, so that the collecting hopper 14 can be fixed below the support frame 12. When the sewage carrying fallen leaves and garbage falls into the inlet pipe 11, the fallen leaves and garbage will be intercepted by the collecting hopper 14, and the sewage will flow out through the drain hole of the collecting hopper 14, so as to prevent the fallen leaves and garbage from blocking the drainage pipe network 1 and causing sewage overflow. Pulling the anti-falling rod 13 upwards can drive the support frame 12 to move upwards, and the collecting hopper 14 can be driven to move upwards by the screw rod 15 and the nut 16 and separate from the inlet pipe 11. At this time, after unscrewing the nut 16, the collecting hopper 14 below the support frame 12 can be removed, so that the fallen leaves and garbage in the collecting hopper 14 can be easily cleaned. The guide plate 17 limits the upward turning angle of the flap 18, and the guide plate 17 can guide the sewage flowing out of the drain hole of the collecting hopper 14 to the right side of the flap 18, so that the sewage can more easily overcome the elastic force of the torsional spring 2 and drive the flap 18 to turn downward, so that the sewage can flow into the drainage pipe network 1. When the top of the flap 18 is not covered with sewage, the torsional spring 2 drives the flap 18 to move upward and reset, closing the inlet pipe 11, so as to reduce the upward flow of sewage in the drainage pipe network 1 and affect the air quality in the city.
