[0017] The following is combined with Figure 1-3 This application is described in further detail.

[0018] The present application discloses a rainwater collection and purification device. Figure 1-3, a rainwater collection and purification device includes a box body 1, a water diversion pipe 2 is installed on the top of the box body 1, and several rain collecting components 3 are installed on the water diversion pipe 2. The rain collecting component 3 includes a diversion pipe 304 connected to the water diversion pipe 2, and a rain collecting cover 301 is installed on the upper end of the diversion pipe 304. The design of the rain collecting cover 301 can collect rainwater to the maximum extent, and collect and transport it into the box body 1 through the diversion pipe 304. A grid plate 302 is installed on the top of the rain collecting cover 301, and a filter plate 303 is installed on the inner side of the grid plate 302. A layer of sand and gravel can be laid on the upper side of the filter plate 303. Large garbage in the rainwater, such as leaves, plastic bags, etc., is intercepted by the grid plate 302 to prevent them from entering the subsequent purification process. The filter plate 303 and the sand and gravel layer thereon perform preliminary filtration on the rainwater, remove some suspended matter and particulate matter, and at the same time improve the anti-clogging ability.

[0019] Reference Figure 3 , a filter assembly 5 is installed in the box body 1, and the filter assembly 5 includes a drainage channel 501 hingedly installed in the box body 1, and a composite filter element plate 503 is installed in the middle of the drainage channel 501. The composite filter element plate 503 is designed with an internal interlayer of a polytetrafluoroethylene filter mesh filled with activated carbon. A guide plate is welded on the lower side of the drainage channel 501, and a slide is provided on the guide plate. A hinge shaft is installed in the slide, and the end of the hinge shaft is rotatably connected to the composite filter element plate 503. A partition plate 7 is installed at the lower end of the composite filter element plate 503, and the bottom end of the box body 1 is divided into a clean water chamber and a sewage chamber by the partition plate 7 to collect clean water and sewage respectively. Drain holes are provided on the side walls of the clean water chamber and the sewage chamber, and a drain valve 8 is installed in the drain hole. Among them, the clean water in the clean water chamber can be discharged through the drain valve 8 to connect the pipe and can be used for irrigation and flushing. The clean water in the sewage chamber can be discharged into the sewage pipe through the drain valve 8 to connect the pipe and be uniformly treated by the sewage treatment station.

[0020] Reference Figure 3 A flushing assembly 6 is also installed on the drainage channel 501. The flushing assembly 6 includes multiple water distribution pipes 601 installed on the drainage channel 501. Several nozzles 602 are installed on the water distribution pipes 601. Two adjacent water distribution pipes 601 are connected to each other. Several nozzles 602 are respectively installed on the corresponding water distribution pipes 601. A water supply pipe 603 is installed on one of the water distribution pipes 601, and the water supply pipe 603 is connected to an external high-pressure water supply device. The high-pressure water supply device uses a high-pressure pump connected to the clean water chamber through a pipeline. Clean water can be drawn from the clean water chamber by the high-pressure pump and supplied to the water distribution pipe 601 and the water supply pipe 603. The composite filter element plate 503 is flushed through the water supply pipe 603 to clean the generated sewage and discharge it into the drainage channel 501 through the drainage channel 501 inclined toward the sewage chamber.

[0021] Reference Figure 3A guide plate 4 is installed on the top of the box body 1, and the water outlet of the guide plate 4 is located on the inner side of the drainage channel 501. Several ultraviolet disinfection lamps 9 are installed on the lower side of the drainage channel 501. The ultraviolet disinfection lamps 9 are located above the clean water chamber, and a waterproof cover is installed on the outside of the ultraviolet disinfection lamps 9. The rainwater is disinfected by the ultraviolet disinfection lamps 9. At the same time, drip grooves are installed at both ends of the drainage channel 501 to prevent rainwater from flowing along the bottom of the drainage channel 501.

[0022] The implementation principle of a rainwater collection and purification device in the embodiment of the present application is as follows:

[0023] Rainwater first falls onto rain collection cover 301, where large debris, such as leaves and plastic bags, is intercepted by grid plate 302, preventing it from entering the subsequent purification process. Filter plate 303 and the gravel layer above it perform preliminary filtration on the rainwater, removing some suspended matter and particulate matter while also improving its anti-clogging capabilities. The preliminarily filtered rainwater is then transported through diversion pipe 304 into housing 1 for further purification.

[0024] When collecting rainwater normally, the telescopic cylinder 502 is in a state of tilting the drainage channel 501 toward the clean water chamber, guiding the rainwater through the guide plate 4 and the drainage channel 501. A composite filter element plate 503 is installed in the middle of the drainage channel 501 to deeply filter the rainwater and remove smaller impurities and pollutants. The clean water enters the clean water chamber. Above the clean water chamber, the ultraviolet disinfection lamp 9 disinfects the filtered clean water to ensure water quality safety.

[0025] To maintain the cleanliness and filtration efficiency of the composite filter element plate 503, a flushing assembly 6 is installed for regular flushing. During flushing, the telescopic cylinder 502 operates, causing the drainage channel 501 to rotate, switching from an inclined position toward the clean water chamber to an inclined position toward the sewage chamber. A high-pressure pump then supplies water to the water supply pipe 603. High-pressure clean water is fed into the water distribution pipe 601 and sprayed out through the nozzle 602, powerfully flushing the composite filter element plate 503. The sewage generated by flushing flows back to the sewage chamber along the inclined drainage channel 501.
