When the water phases in the first bent pipe and the second bent pipe of the U-shaped pipe are the same, the balance positions of the piston and the spring are positioned at the joint of the first bent pipe and the second bent pipe; at the moment, the piston seals the joint of the two sections of bent pipes, so that pests, mice and stink from the left sewage discharge pipeline are effectively prevented.

When the water level of the second elbow of the U-shaped pipe is higher than that of the first elbow, the piston and the spring move towards the first elbow under the action of water pressure; the horizontal pipeline is opened, and the sewage from the right pipeline can be discharged to the left sewage discharge pipeline through the U-shaped pipe.

When the water level of the first bent pipe of the U-shaped pipe is higher than that of the second bent pipe, the piston tightly blocks the joint of the first bent pipe and the second bent pipe. Under the action of water pressure, the piston tightly blocks the joint of the two sections of bent pipes, thereby effectively preventing rainwater from flowing backwards.

The utility model has the advantages that:

The utility model discloses a spring protection against rodents rain-proof water flows back U type pipe, in the coaxial bending pipeline horizontal pipe that the internal diameter that is connected in the horizontal direction is different, set up a miniature resilient means, when the left and right water level highly uniform of U type pipe or left water level be higher than right-hand time, effectively prevent to come from the stink of connecting left sewage pipes and upwelling, the rainwater flows back, and the mouse gets into the scheduling problem. When the water level at the right side of the U-shaped pipe is higher than that at the left side, the dirt from the pipeline at the right side can be discharged to the sewage discharge pipeline at the left side through the U-shaped pipe.

The utility model discloses simple structure, the use restriction is little, and the reliability is high, can effectively solve general domestic lavatory closestool, gushes on kitchen sink department stench, and the mouse gets into and the rainwater flows backward the scheduling problem, has very strong practicality and extensive suitability.

Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the utility model relates to a spring type rat-proof rainwater backflow-proof U-shaped pipe, the main body of the pipe comprises two sections of fixedly connected bent pipes, namely a bent pipe I and a bent pipe II, wherein the inner diameter of the bent pipe I is larger than that of the bent pipe II, and the height of the vertical section of the bent pipe I is smaller than that of the vertical section of the bent pipe II; an elastic device is fixedly arranged in the horizontal section of the U-shaped pipe.

The elastic device of the utility model comprises a connecting rod 4 which is coaxial with the horizontal section of the U-shaped pipe and plugs which are respectively arranged on the two bending pipelines, and two ends of the connecting rod 4 are fixed in the horizontal section pipeline through the plugs 1; the connecting rod 4 is sleeved with a spring 2; the largest sectional area of the spring 2 is smaller than the inner diameter of the first bent pipe, one end of the spring 2 is fixedly connected to a plug of the first bent pipe, and the other end of the spring is connected with the baffle 3; the sectional area of the baffle piece 3 is larger than the inner diameter of the bent pipe II, and the baffle piece 3 can move along the direction of the connecting rod 4; the moving range of the baffle 3 and the telescopic range of the spring 2 are both in the pipeline of a horizontal section of the elbow.
