[0013] The advantages of this utility model are:

[0014] 1. This utility model features a multi-stage filtration system. The device employs a tiered filtration structure with larger, medium, and smaller filter screens, progressively removing impurities from rainwater. This design effectively intercepts particles of varying sizes, purifying rainwater step-by-step from large to small particles. Multi-stage filtration significantly improves filtration efficiency, reduces the burden on individual filter screens, and extends their lifespan. Tiered filtration effectively removes most impurities from rainwater, improving its quality and making it more suitable for irrigation, landscaping, or other non-potable applications. The medium-sized filter screen, connected to the outer casing by a slider and groove, allows for easy removal for cleaning and replacement. This detachable structure significantly reduces maintenance costs and workload. The slider and medium-sized filter screen are integrated, enhancing the stability and reliability of the structure and preventing the filter screen from loosening or shifting during use. The water guide channel inside the larger filter screen can guide rainwater to be evenly distributed, avoiding concentrated water flow impacting the filter screen, reducing local wear, and extending service life. The water guide channel ensures that rainwater fully contacts the filter screen during the filtration process, improving the filtration effect, while reducing water flow resistance and improving the overall operating efficiency of the device.

[0015] 2. This utility model, by incorporating storage and cleaning components, allows rainwater that has undergone multi-stage filtration to further settle, removing residual fine particles and impurities. A drain outlet on one side of the sedimentation tank periodically discharges settled impurities, preventing accumulation and blockage. The settled clear water flows into a clear water tank, further isolating impurities and ensuring water quality stability. The clear water tank serves as a transitional area for storage and transportation, providing a clean water source for subsequent pressurization and reuse. A partition plate separates the sedimentation tank and the clear water tank, preventing sediment from re-mixing into the purified water and improving water quality stability. A booster pump draws purified rainwater from the clear water tank through a pumping pipe and delivers it to the sprinkler heads through an outlet pipe. The booster pump ensures that rainwater is delivered to the water usage points at sufficient pressure.

[0016] 3. This utility model, by incorporating a support component, allows users to adjust the height of the support component according to the actual installation environment (such as uneven ground, platforms of different heights, etc.) by rotating the inner threaded rod, ensuring the overall levelness and stability of the device. During installation, the height of the device can be adjusted as needed without the need for additional shims or other support materials, simplifying the installation process. The threaded connection between the threaded rod and the inner threaded rod provides a reliable mechanical connection, ensuring that the support component will not loosen or slip during operation. The design of the support plate increases the contact area with the ground, distributing the weight of the device and further improving its stability. Attached Figure Description

A larger filter screen 106 is fixedly connected to the top of the housing 101, and a water guiding groove 107 is provided inside the larger filter screen 106. The medium-sized filter screen 104 forms a sliding structure with the housing 101 through the slider 103, the groove 102, and the slider 103 and the medium-sized filter screen 104 are integrated.

[0027] Please see Figure 3 The rainwater collection device with filtration function is shown. The storage and cleaning component 2 includes a sedimentation tank 201. A sewage outlet 202 is fixedly connected to one side of the sedimentation tank 201, and a partition plate 203 is fixedly connected to the other side of the sedimentation tank 201. A clear water tank 204 is fixedly connected to the other side of the partition plate 203. A water pump 205 is fixedly connected inside the clear water tank 204. A booster pump 206 is fixedly connected to the end of the water pump 205.

The clear water tank 204 and the booster pump 206 are connected through the water pump 205, and the booster pump 206 is connected to the spray head 208 through the outlet pipe 207.

[0028] Please see Figure 4 The rainwater collection device with filtration function is shown. The support component 3 includes a threaded rod 301. The outer wall of the threaded rod 301 is threaded with an inner threaded rod 302. The bottom of the inner threaded rod 302 is fixedly connected to a support plate 303, and the bottom of the support plate 303 is fixedly connected to a rubber pad 304. The threaded rod 301 and the inner threaded rod 302 are arranged with their vertical central axes coincident, and the support plate 303 forms a lifting structure with the threaded rod 301 through the inner threaded rod 302.

[0029] Working Principle: Rainwater first enters through a larger filter screen 106 at the top of the device. The water guide channel 107 inside the larger filter screen 106 guides the rainwater to distribute evenly, while simultaneously intercepting larger impurities, such as leaves and twigs, preventing them from entering the subsequent filtration system. The rainwater, after initial filtration, flows into the housing 101 and continues through a medium-sized filter screen 104. The medium-sized filter screen 104 forms a sliding structure with the housing 101 via a slider 103 and a groove 102, facilitating disassembly and cleaning, and further intercepting medium-sized impurities, purifying the rainwater. Subsequently, the rainwater passes through a smaller filter screen 105, removing even finer particles and suspended solids, completing a multi-stage filtration process. At this point, the rainwater becomes clearer, with a significantly reduced impurity content. The rainwater, after multi-stage filtration, flows into a sedimentation tank 201, where residual fine particles and impurities further settle. A drain outlet 202 on one side of the sedimentation tank 201 periodically discharges the sediment to prevent accumulation and blockage. After sedimentation, the clear water flows into the clear water tank 204 through the dividing plate 203. The clear water tank 204 serves as a storage area, providing a clean water source for subsequent reuse. Rainwater in the clear water tank 204 is drawn by the booster pump 206 through the pumping pipe 205. The booster pump 206 provides sufficient pressure to deliver the rainwater to the sprinkler head 208 through the outlet pipe 207. The sprinkler head 208 sprays the pressurized rainwater for irrigation, landscaping, or other non-potable uses, achieving efficient reuse of rainwater and reducing dependence on municipal water supply. The support assembly 3 at the bottom of the device provides stable support through the threaded connection of the threaded rod 301 and the internal threaded rod 302. The vertical central axes of the threaded rod 301 and the internal threaded rod 302 coincide, ensuring the stability of the support structure. The support plate 303 moves up and down on the threaded rod 301 via the internal threaded rod 302, allowing for height adjustment to adapt to different installation environments. The rubber pad 304 at the bottom of the support plate 303 serves to cushion, prevent slipping, and protect the ground, further enhancing the stability and service life of the device. The entire device achieves efficient purification of rainwater through multi-stage filtration components 1, sedimentation and reuse through storage and cleaning components 2, and stable support components 3 that allow for height adjustment. The device is rationally designed, operates efficiently, is easy to maintain, and has good adaptability and practicality.
