[0002] Urban drainage pipes are a vital infrastructure for the normal operation of a city, requiring the safe and timely collection and discharge of urban rainwater and sewage. Urban drainage systems mix sewage, industrial wastewater, and rainwater in the same pipe network. Direct discharge into natural water bodies would cause severe pollution, while direct discharge into sewage treatment plants would result in large amounts of relatively clean rainwater undergoing unnecessary treatment, leading to resource waste.

[0003] Existing urban drainage separation structures typically have filters installed inside their drainage channels to separate silt and other impurities. However, silt, leaves, and other foreign objects accumulate in the drainage channels over time, causing blockages and making it difficult for staff to clean them. Furthermore, the lack of separate sewage pipes in these structures leads to the mixing of sewage and rainwater, resulting in a waste of water resources and hindering water recycling.

[0024] Please see Figure 1-7 This utility model provides the following technical solution: a diversion structure for urban drainage, including a water distribution tank 1 and an inlet hopper 2. A first connecting pipe 3 is fixedly connected to the inside of one side of the water distribution tank 1, and the other end of the first connecting pipe 3 is connected to the center of the bottom of the inlet hopper 2. A support frame 19 is fixedly installed at the center of the inner surface of the inlet hopper 2. An elastic telescopic rod 23 is fixedly connected to the top of the support frame 19. A connecting block 21 is fixedly connected to one end of the elastic telescopic rod 23. A return spring 22 is sleeved in the middle of the surface of the elastic telescopic rod 23, and the other end of the return spring 22 is connected to the inside of the connecting block 21. A cover plate 10 is provided on the top of the connecting block 21. An inlet 11 is opened on the surface of the cover plate 10. An internal hexagon bolt is provided at the center of the surface of the cover plate 10. 8. The other end of the hexagonal socket bolt 8 passes through the inside of the cover plate 10 and is internally threaded to the center of the connecting block 21. The bottom of the cover plate 10 is fixedly connected to the movable block 18. The inside of the water tank 1 is fixedly connected to one side of the second guide pipe 14. One end of the second guide pipe 14 is connected to the sealing gasket 15. One end of the sealing gasket 15 is connected to the diversion box 4. The inside of one side of the diversion box 4 is connected to the second connecting pipe 25. One end of the second connecting pipe 25 is connected to the second anti-backflow curved pipe 26. One end of the second anti-backflow curved pipe 26 is connected to the drain pipe 27. The inside surface of the water inlet hopper 2 is fixedly connected to the slide rail 20. The slide rail 20 has a limit groove 17 inside, and the surface of the limit groove 17 is movably connected to the surface of the movable block 18.

[0025] In this embodiment, the baffle 13 divides the interior of the water distribution tank 1 into two independent chambers, so that sewage and rainwater do not come into contact, avoiding sewage pollution of rainwater, and facilitating the recycling of rainwater after drainage diversion, thereby reducing the waste of water resources.

[0026] In this embodiment, the sewage pipe 7 is connected to the corresponding sewage pipe through the connecting ring 12, which facilitates the independent discharge and treatment of sewage. Sewage and rainwater do not use the same pipe, thus avoiding sewage pollution of other water and facilitating discharge and treatment.

[0027] In this embodiment, the protective net 9 can isolate foreign objects such as mud, sand, and leaves from the ground to the outside of the water inlet 2, preventing a large amount of mud, sand, leaves, and other foreign objects from accumulating inside the water inlet 2 and causing blockage of the pipes, thus reducing the burden on workers during cleaning.

[0028] In this embodiment, the filter screen 24 can perform preliminary filtration of rainwater, reducing impurities in the rainwater and facilitating subsequent treatment and recycling of rainwater.

[0029] The working principle and usage process of this utility model are as follows: After the utility model is installed, when a heavy object presses on the surface of the cover plate 10, the elastic telescopic rod 23 will retract, thereby causing the cover plate 10 and the protective net 9 to retract. The movable block 18 will move downward along the limiting groove 17. After the heavy object leaves, the return spring 22 will return the cover plate 10 to its initial position. Rainwater flows into the interior of the water inlet 2 through the water inlet 11. Foreign objects such as leaves and mud on the ground will be isolated outside the water inlet 2 by the protective net 9. The water inside the water inlet 2 is filtered by the filter screen 24 and flows into the interior of the water distribution tank 1 from the interior of the first connecting pipe 3. Then, it flows into the interior of the water distribution box 4 through the second guide pipe 14, and finally flows into the second connecting pipe connected to one side through the water distribution box 4. The rainwater inside the second connecting pipe 25 increases and eventually enters the second anti-backflow curved pipe 26 and is discharged through the drain pipe 27. The discharged rainwater can be recycled. The sewage pipe 7 is connected to the corresponding sewage pipe through the connecting ring 12. The sewage flows into the other side of the water distribution tank 1 through the sewage pipe 7. The inside of the water distribution tank 1 is divided into two by the baffle 13. The sewage and rainwater are independent of each other. The sewage flows into the inside of the first anti-backflow curved pipe 16 through the first guide pipe 5 and is finally discharged to the corresponding position through the sewage pipe. After the diversion is completed, the hex bolt 8 is unscrewed, the cover plate 10 is removed, and the inside of the water inlet hopper 2 is cleaned. Finally, the cover plate 10 is put back in place, the hex bolt 8 is screwed on, and the sewage is treated.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
