Description

Technical Field

[0001] This utility model relates to the field of rainwater utilization technology, and more specifically, to a rainwater collection and recycling device. Background Technology

[0002] Water scarcity is a global problem, and rainwater, as a usable natural water resource, has often been lost due to a lack of collection facilities in the past. This not only wastes resources but can also cause urban flooding and road erosion during periods of heavy rainfall. In rural areas and small households, small, decentralized rainwater harvesting devices are gaining popularity. These devices consist of a simple rain collection shed, a filter bucket, and a storage tank. After collecting rainwater from the roof, it is filtered through a filter screen, and the stored rainwater can be used for irrigating family vegetable gardens, providing drinking water for livestock and poultry, and cleaning yards.

[0003] In existing technologies, collected rainwater contains various impurities such as leaves, silt, and suspended solids. Direct use of this water can easily clog pipes or affect its performance. Single filtration methods are insufficient to completely remove different types of impurities. Rainwater is used in a variety of scenarios, such as greening irrigation which has low water quality requirements, while some miscellaneous uses require higher cleanliness. Traditional devices mostly output a single type of water quality, which cannot meet different needs. Utility Model Content

The device includes a threaded sleeve 14, a threaded lamp cover 15 that mates with the threaded sleeve 14 on the outside of the ultraviolet lamp 13, a second water outlet pipe 16 on one side of the disinfection box 11, a baffle plate 17 inside the filter box 1, a baffle 18 on one side of the baffle plate 17, a water outlet 19 on the baffle 18, a filter screen 20 on one side of the baffle 18, a filter element plate 21 on one side of the filter screen 20, a first sealing gasket 22 between the threaded lamp cover 15 and the lamp holder 12, a second sealing gasket 23 on the threaded sleeve 14, and an abutment ring 24 on the threaded lamp cover 15 that mates with the second sealing gasket 23.

[0022] In this embodiment, rainwater is collected by the collection box 3 and filtered by the collection filter 5. After the rainwater gathers in the filter box 1, it causes the float 8 to float, opening the collection pipe 2 to facilitate rainwater collection and replenishment of the water source. The water is blocked by the flow baffle 17, causing suspended solids in the water to initially settle on the left side of the flow baffle 17. Then, the water flows through the top of the flow baffle 17 to the left side of the baffle 18, where it is further blocked and settled. The water then flows through the outlet 19 to the left side of the filter screen 20. After that, the water continues to flow to the right, being filtered by the filter screen 20 and the filter element plate 21 in sequence, thereby effectively removing water. Impurities in the water are removed, and some of the water enters the disinfection box 11 through the connecting pipe 10. The ultraviolet lamp 13 is installed on the lamp holder 12, and the threaded lamp cover 15 is installed on the threaded sleeve 14 to protect the ultraviolet lamp 13. The cooperation of the first sealing gasket 22 and the second sealing gasket 23 improves the tightness of the connection between the threaded lamp cover 15 and the lamp holder 12, as well as between the threaded lamp cover 15 and the threaded sleeve 14. The ultraviolet lamp 13 disinfects the water in the disinfection box 11, improving the cleanliness of the rainwater. Processes with low water quality requirements take water through the first water outlet pipe 9, while processes with high rainwater cleanliness take water through the second water outlet pipe 16.

[0023] Please see Figure 5As one embodiment of the connecting device: the connecting device includes a connecting block 25, which is mounted on a fixed frame 4. A snap-fit ​​block 26 is rotatably mounted on the connecting block 25. A limiting groove 27 is provided on the snap-fit ​​block 26. A limiting plate 28 is slidably mounted on the limiting groove 27. Limiting rods 29 are symmetrically mounted on the limiting plate 28. A limiting hole 30 that cooperates with the limiting rod 29 is provided on the connecting block 25. A limiting spring 31 is provided between the limiting plate 28 and the limiting groove 27. A limiting handle 32 is provided at one end of the limiting plate 28.

[0024] More specifically, when installing and replacing the collection filter 5, rotate the locking block 26. When the limiting rod 29 on the locking block 26 is aligned with the limiting hole 30 of the connecting block 25, the limiting plate 28, under the elastic force of the limiting spring 31, drives the limiting rod 29 into the limiting hole 30, fixing the position of the locking block 26. The position of the collection filter 5 is fixed by the locking block 26. When disassembling the collection filter 5, pull the limiting handle 32 upward. The limiting handle 32 drives the limiting plate 28 to compress the limiting spring 31, causing the limiting rod 29 to leave the limiting hole 30. Rotate the locking block 26. When the locking block 26 is aligned with the connecting block 25, the collection filter 5 can be disassembled.

[0025] In summary, during use or operation of the entire device: rainwater is collected through the collection box 3 and filtered through the collection filter 5. After the rainwater gathers in the filter box 1, it causes the float 8 to float, opening the collection pipe 2 to facilitate rainwater collection and replenishment of the water source. The water is blocked by the flow baffle 17, causing suspended solids in the water to initially settle on the left side of the flow baffle 17. Then, the water flows through the top of the flow baffle 17 to the left side of the baffle 18, where it is further blocked and settled. The water then flows through the outlet 19 to the left side of the filter screen 20. After that, the water continues to flow to the right, being filtered sequentially by the filter screen 20 and the filter element plate 21, thus... The system effectively removes impurities from the water. Some of the water enters the disinfection tank 11 through the connecting pipe 10. The ultraviolet lamp 13 is installed on the lamp holder 12, and the threaded lamp cover 15 is installed on the threaded sleeve 14 to protect the ultraviolet lamp 13. The cooperation of the first sealing gasket 22 and the second sealing gasket 23 improves the tightness of the connection between the threaded lamp cover 15 and the lamp holder 12, as well as between the threaded lamp cover 15 and the threaded sleeve 14. The ultraviolet lamp 13 disinfects the water in the disinfection tank 11, improving the cleanliness of the rainwater. Processes with low water quality requirements take water through the first water outlet pipe 9, while processes with high rainwater cleanliness take water through the second water outlet pipe 16.

[0026] When installing or replacing the collection filter 5, rotate the locking block 26. When the limiting rod 29 on the locking block 26 is aligned with the limiting hole 30 of the connecting block 25, the limiting plate 28, under the elastic force of the limiting spring 31, drives the limiting rod 29 into the limiting hole 30, fixing the position of the locking block 26. The position of the collection filter 5 is fixed by the locking block 26. When disassembling the collection filter 5, pull the limiting handle 32 upward. The limiting handle 32 drives the limiting plate 28 to compress the limiting spring 31, causing the limiting rod 29 to leave the limiting hole 30. Rotate the locking block 26. When the locking block 26 is aligned with the connecting block 25, the collection filter 5 can be disassembled.
