Description

Technical Field

[0001] This utility model relates to the field of rainwater harvesting technology, and in particular to a design structure for rainwater harvesting in sponge cities. Background Technology

[0002] Sponge city construction is a new model for planning and building cities based on ecological and sustainable principles. It aims to make cities, like sponges, highly resilient in adapting to environmental changes and responding to natural disasters. When it rains, the city absorbs, stores, infiltrates, and purifies water, and when needed, it releases and utilizes the stored water. This enhances the function of the urban ecosystem and reduces urban flooding. Rainwater harvesting is a crucial component of sponge city construction.

[0003] When collecting rainwater from the ground, the rainwater is usually initially filtered before entering the collection structure to reduce the processing pressure on the rainwater after collection. During the initial filtration, some debris often gets stuck in the filter structure, which is very troublesome to clean and often requires disassembling the filter structure. When the rainwater collection system is not in use, external debris can also easily get stuck in the filter structure, affecting the subsequent rainwater collection. Utility Model Content

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0020] like Figures 1 to 4 As shown, a preferred embodiment of a sponge city rainwater harvesting design structure is illustrated, comprising:

[0021] The system comprises a water storage tank 1, a recycling tank 2, a connecting pipe 3, a filter assembly, a purification tank 4, a dredging assembly, a water pump 5, and a drain pipe 6. The water pump 5 and the drain pipe 6 are both installed inside the water storage tank 1. One end of the drain pipe 6 is installed at the outlet of the water pump 5, and the other end of the drain pipe 6 passes through the side wall of the water storage tank 1. The upper end of the connecting pipe 3 is connected to the lower surface of the recycling tank 2, and the lower end of the connecting pipe 3 is connected to the upper surface of the water storage tank 1. The filter assembly and the purification tank 4 are both installed inside the recycling tank 2. The filter assembly is positioned above the purification tank 4. The upper surface of the purification tank 4 has an inlet hole, and the lower surface of the purification tank 4 has an outlet hole. The dredging assembly is movably installed in the recycling tank 2. The upper surface of the recycling tank 2 has several drainage holes 7. The dredging assembly has several dredging rods 8, which can be operably inserted into or removed from the drainage holes 7.

[0022] In actual use, both the water storage tank 1 and the recycling tank 2 are located underground. The upper surface of the recycling tank 2 is flush with the ground. The other end of the drain pipe 6 and the other end of the liquid level control pipe 18 are connected to the external drainage system. Tightening the upper end of the drive screw 16 causes the drive screw 16 to engage with the threaded hole 23 on the positioning plate 14, thereby driving the positioning plate 14 to move downwards in the vertical direction. The positioning plate 14 then drives several unblocking rods 8 to move downwards until the unblocking rods 8 disengage from several drainage holes 7. At this time, rainwater from the outside can enter the recycling tank 2 through the drainage holes 7, be filtered by the filter screen 13, and then enter the purification tank 4 for purification. Then, it enters the water storage tank 1 through the connecting pipe 3 and is discharged through the water pump 5 and the drain pipe 6. When the rainwater in the water storage tank 1 is full, the liquid level will rise to the position of the liquid level control pipe 18. At this time, the excess rainwater can flow into the external drainage system through the liquid level control pipe 18, preventing rainwater from overflowing from the recycling tank 2. During or after rainwater harvesting, some impurities often get stuck in the drainage holes 7. Tighten the upper end of the drive screw 16 to move the positioning plate 14 vertically upward until several drainage rods 8 are inserted into several drainage holes 7 to poke out the impurities stuck in the drainage holes 7.

[0023] Furthermore, as a preferred embodiment, the recycling bin 2 includes an end cap 9 and a bin body 10. The upper surface of the bin body 10 is open and forms an opening. The end cap 9 covers the opening, and the upper surface of the end cap 9 has a plurality of drainage holes 7. A drainage component is movably installed on the end cap 9. Furthermore, by providing the end cap 9, it is convenient to clean the inside of the bin body 10.

[0024] Furthermore, in a preferred embodiment, the filter assembly includes: a pull rod 11, a mounting plate 12, and a filter body 13. The lower end of the pull rod 11 is mounted on the upper surface of the mounting plate 12. The mounting plate 12 has a mounting hole. The outer edge of the filter body 13 is mounted on the inner wall of the mounting hole. Two mounting blocks 21 are provided on the inner walls of both sides of the water storage tank 1. Both mounting blocks 21 are positioned above the purification box 4. The lower surface of the mounting plate 12 rests on the upper surface of the two mounting blocks 21. Furthermore, the mounting plate 12 can be easily and quickly removed from the box 10 using the pull rod 11.

[0025] Furthermore, as a preferred embodiment, activated carbon is placed inside the purification box 4. This further enhances the purification effect by using activated carbon to purify rainwater.

[0026] Furthermore, in a preferred embodiment, the unblocking assembly further includes: a positioning plate 14, a limiting rod 15, and a driving screw 16. The upper end of the limiting rod 15 is mounted on the lower surface of the end cap 9. The upper surface of the positioning plate 14 has a limiting hole 22 and a threaded hole 23. The limiting rod 15 is slidably engaged with the limiting hole 22. The upper surface of the end cap 9 has a countersunk hole 20. The upper end of the driving screw 16 is rotatably mounted in the countersunk hole 20, and the lower end of the driving screw 16 is threadedly engaged with the threaded hole 23. The lower ends of several unblocking rods 8 are all mounted on the upper surface of the positioning plate 14. Furthermore, through the cooperation of the limiting rod 15 and the driving screw 16, the positioning plate 14 is moved vertically, thereby moving several unblocking rods 8 to clean several drainage holes 7.

[0027] Furthermore, in a preferred embodiment, a limiting ring 17 is formed by extending radially outward from the lower end of the limiting rod 15, and the upper surface of the limiting ring 17 is operably in contact with the lower surface of the positioning plate 14. Further, the limiting ring 17 is used to restrict the positioning plate 14, preventing the positioning plate 14 from falling off the limiting rod 15.

[0028] Furthermore, as a preferred embodiment, it further includes a sealing gasket, the lower surface of which is mounted on the upper surface of the positioning plate 14, and the upper surface of the sealing gasket is operably in contact with the lower surface of the end cap 9. Furthermore, the sealing gasket ensures a sealing contact between the upper surface of the positioning plate 14 and the lower surface of the end cap 9, thereby improving the sealing performance.

[0029] Furthermore, as a preferred embodiment, it also includes: a liquid level control pipe 18, and a drain hole 19 is formed on the outer wall of the tank 10, located below the purification tank 4. One end of the liquid level control pipe 18 is installed in the drain hole 19. Further, when the rainwater in the water storage tank 1 is full, the liquid level will rise to the position of the liquid level control pipe 18. At this time, excess rainwater can flow into the external drainage system through the liquid level control pipe 18, preventing rainwater from overflowing from the recovery tank 2. Even further, there are two liquid level control pipes 18 and two drain holes 19, respectively formed on the outer walls of both sides of the tank 10, to improve drainage efficiency.
