A plurality of high-pressure spray heads 8 are evenly installed on the moving plate 7. The high-pressure spray heads 8 communicate with the moving plate 7. The guide rod 15 is welded to the left side inside the collection frame 1. The bidirectional threaded rod 14 is rotatably connected to the right side inside the collection frame 1. The moving plate 7 is slidably connected to the guide rod 15 and is threadedly connected to the bidirectional threaded rod 14. The high-pressure spray heads 8 are located below the first filter screen 2. The high-pressure spray heads 8 can spray water onto the first filter screen 2 to clean the impurities on the first filter screen 2. A water pumping assembly for delivering water source is provided inside the collection frame 1.

[0023] As Figures 2-5As shown in the figure, the pumping assembly includes a water inlet pipe 9, a water pump 10, an impeller 11, a first gear 12, a second gear 13, a delivery pipe 16 and a telescopic pipe 17. A water pump 10 is installed on the right side of the rear part inside the collection frame 1. The water inlet pipe 9 is connected below the water pump 10. The delivery pipe 16 located inside the collection frame 1 is connected above the water pump 10. The delivery pipe 16 is connected to the collection frame 1. And a telescopic pipe 17 is connected between the left end of the delivery pipe 16 and the moving plate 7. The telescopic pipe 17 is located inside the collection frame 1. The impeller 11 is rotatably connected to the right side inside the delivery pipe 16. The first gear 12 is connected to the front side of the impeller 11. The second gear 13 is connected to the rear side of the bidirectional threaded rod 14. The first gear 12 meshes with the second gear 13. The first gear 12 and the second gear 13 are both located inside the collection frame 1.

[0024] As Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 shown, the collection module further includes a collection box 19, a third filter screen 20, a clamping block 22 and a handle 23. A sewage outlet 18 is opened on the front side inside the collection frame 1. The collection box 19 is slidably connected to the front side of the collection frame 1. The collection box 19 communicates with the sewage outlet 18. The third filter screen 20 is connected to the rear side of the collection box 19. The impurities on the first filter screen 2 will fall into the collection box 19 through the sewage outlet 18 after being washed by the high-pressure nozzle 8. A through hole 25 for sewage discharge is opened at the position on the collection frame 1 behind the collection box 19. Clamping grooves 21 are opened on both the left and right side walls of the collection box 19. The clamping blocks 22 are symmetrically and fixedly connected to the front side of the collection frame 1 on the left and right. The clamping blocks 22 are clamped with the clamping grooves 21 on the same side to limit the collection box 19. The handle 23 is connected to the front side of the collection box 19.

[0025] The collection module can be built on an open-air rainwater collection pool and an underground storage tank. The collection module is used in conjunction with a water tank and is installed on the water tank. When rainwater falls on the collection module, it will be filtered by the first filter screen 2 and the second filter screen 6 and stored in the water tank. An external pipe connects the water tank and the water inlet pipe 9. During the rainy season, when rainwater falls on the collection module, it will flow downward through the first filter screen 2 to the flow splitter 4, and then be collected in the water tank after passing through the second filter screen 6. After long-term use, a large amount of impurities will remain on the first filter screen 2. The water pump 10 can be started. The water pump 10 will pump the water in the water tank through the water inlet pipe 9 into the delivery pipe 16, and then flow into the moving plate 7 through the telescopic pipe 17. The water will be sprayed from the high-pressure nozzle 8 onto the first filter screen 2. When the water enters the delivery pipe 16, it will drive the impeller 11 to rotate. The impeller 11 drives the first gear 12 and the second gear 13 to rotate. The second gear 13 drives the bidirectional threaded rod 14 to rotate. The bidirectional threaded rod 14 can drive the moving plate 7 to move forward along the guide rod 15. The moving plate 7 will drive the high-pressure nozzle 8 to move forward. The telescopic pipe 17 will gradually extend, and the high-pressure nozzle 8 will gradually move forward. Through the impact of the water flow, the impurities on the first filter screen 2 can be pushed forward, and the impurities will enter the collection box 19 through the sewage outlet 18. After the moving plate 7 moves forward to the limit, the bidirectional threaded rod 14 will drive the moving plate 7 and the high-pressure nozzle 8 to move backward and reset, causing the telescopic pipe 17 to shorten and reset. The continuous rotation of the bidirectional threaded rod 14 can drive the high-pressure nozzle 8 to move back and forth repeatedly to effectively clean the first filter screen 2. When the sundries enter the collection box 19, they will also carry sewage. The sewage contained in the impurities will be discharged after passing through the third filter screen 20. The external pipe is on the through hole 25, and the filtered sewage can be collected and cleaned, or discharged to the ground. After the first filter screen 2 is cleaned, the water pump 10 can be turned off. In this way, the first filter screen 2 can be cleaned by using the originally collected rainwater, ensuring the stable progress of rainwater collection work, avoiding the blockage of the first filter screen 2, and the automatic cleaning also provides convenience for the staff. When cleaning the collection box 19, the handle 23 can be pulled by hand to pull the collection box 19 forward to clean the inside of the collection box 19. After cleaning, align the card slot 21 on the collection box 19 with the clamping block 22, and push the collection box 19 back into the collection frame 1. The clamping block 22 can play a role in limiting and fixing the collection box 19, improving the stability of the collection box 19.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the protection scope of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the essence and scope of the technical solutions of the present invention.
