[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0024] refer to Figure 1~Figure 4 The first aspect of the utility model protects an anti-blocking structure, which is arranged at the bottom end of the terminal drainage pipe, so that the top end of the anti-blocking structure is connected to the bottom end of the terminal drainage pipe, and the anti-blocking structure includes a variable diameter pipe body 1, and a dredging member 2 and a moving member 3 are arranged in the pipe body 1. The variable diameter pipe body 1 has different diameters at both ends, and the end with a larger diameter is placed at the bottom.
[0025] The moving part 3 is provided with a through hole to allow water to pass through, and the dredging part 2 can pass through the through hole. The through hole has a drainage function.
[0026] The utility model is provided with a moving part 3, which includes a slider 32 and a spring 31. When the slider 32 is blocked, the accumulated water presses the slider 32 to move downward. Since it is a pipe body with a variable diameter, when it moves to a certain position, the water can be discharged from the outside of the slider 32, and the spring 31 pulls the slider 32 to reset. When resetting, the dredging part can pass through the through hole, hit and dredge the blockage, so that the through hole can resume drainage. The utility model is arranged at the bottom end of the terminal drainage pipe, which can automatically dredge the blockage and save manpower.
[0027] refer to Figure 2 or Figure 3 In a specific embodiment, the pipe body 1 includes a first water pipe 11, a second water pipe 12 and a third water pipe 13 connected in sequence, the diameters of the first water pipe 11, the second water pipe 12 and the third water pipe 13 increase in sequence, and the top of the first water pipe 11 is connected to the bottom of the terminal drain pipe. The inner diameter of the second water pipe 12 is larger than the outer diameter of the first water pipe 11, and the inner diameter of the third water pipe 13 is larger than the outer diameter of the second water pipe 12. A connecting plate is provided at the connection between the second water pipe 12 and the first water pipe 11, and at the connection between the third water pipe 13 and the second water pipe 12.
[0028] This embodiment can discharge a large amount of obstructions by arranging water pipes of different diameters and arranging a third water pipe 13 with a large diameter at the bottom. When the water pipe does not drain, the third water pipe 13 at the bottom can also be prevented from growing weeds and causing obstruction.

The shape of the blade 22 in this embodiment is similar to that of a turbine, one end of the blade 22 is connected to the second rod 23, and the other end of the blade 22 is bent obliquely downward. During normal operation, water pushes the blade 22 to drive the second rod 23 to rotate, and the bottom end of the second rod 23 is in the through hole, which can prevent obstructions such as leaves from accumulating in the through hole and prevent clogging. Providing the blade 22 can also increase the rotation speed of the second rod 23, and the effect is better when the second rod 23 clears the through hole.
[0035] refer to Figure 2 In a specific embodiment, the edge of the blade 22 is provided with a blade, which can cut and break leaves. The edge of the blade 22 in this embodiment is a blade, which can break large leaves when rotating to prevent large leaves from clogging in the through hole.
