[0026] Refer to Figure 3, further get, rainwater treatment assembly 4 has processing pipe one 5, processing pipe two 6, processing pipe three 7, processing pipe three 7 is fixedly installed at the front end water inlet of rainwater collection tank 1, processing pipe one 5, processing pipe two 6, processing pipe three 7 are connected with each other by sealing flange one, and processing pipe one 5 is between processing pipe two 6 and processing pipe three 7, the inside central position of processing pipe one 5 is provided with filter screen pipe 8 by mounting disc, the top end of processing pipe one 5 is provided with cleaning spray pipe 9, and cleaning spray pipe 9 extends into the inside of filter screen pipe 8, the end of cleaning spray pipe 9 extending out of processing pipe one 5 is provided with cleaning electromagnetic valve 10, the top end of processing pipe two 6 is provided with water inlet, and the water inlet of processing pipe two 6 is connected with water inlet 18 by sealing flange two, cleaning spray pipe 9 is arranged in "L" shape, and the part of cleaning spray pipe 9 inside filter screen pipe 8 is provided with water spray hole.

[0027] Specifically, by setting the water inlet 18, rainwater can be guided into the processing pipe two 6 when it rains, and then the rainwater enters the rainwater collection tank 1 through the processing pipe two 6, the processing pipe one 5 and the processing pipe three 7 to complete the collection process of the rainwater. When the rainwater passes through the processing pipe one 5, the filter screen pipe 8 inside the processing pipe one 5 can filter the rainwater to remove solid impurities such as dust, dirt and tree leaves that may be contained in the rainwater, preventing gas from entering the rainwater collection tank 1 to improve the collection quality. During the collection process, the cleaning spray pipe 9 is connected to the external cleaning pipe and the cleaning electromagnetic valve 10 is intermittently started to deliver cleaning water to the inside of the processing pipe one 5 for spraying, so as to flush away the impurities and prevent the impurities from adhering to the processing pipe one 5, affecting its normal filtering.

[0028] Example two

[0029] Referring to Figure 2 , Figure 3 and Figure 4 and based on example one, further get, the front end of processing pipe two 6 is provided with stirring motor 11, the driving shaft of stirring motor 11 penetrates the front end of processing pipe two 6 and is fixedly connected with transmission rod, and the front end of transmission rod is provided with helical fan blade 12, the front end of helical fan blade 12 is provided with stirring rod 13 through connecting bolt, the front end of stirring rod 13 is provided with two cleaning scraping blocks 14 through mounting bracket and mounting bolt, the upper and lower opposite surfaces of cleaning scraping block 14 are attached to the outer ring of filter screen pipe 8, the water inlet 18 is conical, the side penetrating the water inlet is provided with water injection pipe 17, and the end of water injection pipe 17 extending out of the water inlet is provided with water injection electromagnetic valve, the outer ring of processing pipe one 5 is provided with impurity deposition box 15 at the lower position, the bottom end of impurity deposition box 15 is connected with discharge pipe, and the connection between impurity deposition box 15 and discharge pipe is provided with discharge electromagnetic valve 16.

[0030] Specifically, by starting the stirring motor 11, its drive shaft can rotate, causing the spiral fan blade 12 and the stirring rod 13 to rotate continuously inside the second treatment tube 6. When a large amount of rainwater is guided into the second treatment tube 6, the continuous rotation of the stirring rod 13 can agitate the water, preventing impurities from settling inside the second treatment tube 6. The continuous rotation of the spiral fan blade 12 can also push the water flow towards the rainwater collection tank 1 to increase the water flow rate. When there is no guided water flow in the second treatment tube 6, the rotation of the spiral fan blade 12 can generate wind to blow the impurities adhering to the first treatment tube 5. When the stirring rod 13 continues to rotate, it will drive the cleaning scraper 14 to rotate against the outer ring of the first treatment tube 5 to scrape off the impurities on the first treatment tube 5.

[0031] In actual operation, rainwater can be guided into treatment pipe 2 6 through the inlet 18 during rain. Then, the rainwater enters the rainwater collection tank 1 through treatment pipe 2 6, treatment pipe 1 5, and treatment pipe 3 7 to complete the rainwater collection process. When the rainwater passes through treatment pipe 1 5, it can be filtered by the filter screen 8 inside treatment pipe 1 5 to filter out solid impurities such as dust particles, floating dust, and tree leaves that may be contained in the rainwater, preventing air from entering the rainwater collection tank 1 with the rainwater, thereby improving the collection quality. During the collection process, the cleaning spray pipe 9 is connected to the external cleaning pipe and the cleaning solenoid valve 10 is activated intermittently to deliver the cleaning water flow to the inside of treatment pipe 1 5 for spraying out, so as to wash away the impurities and prevent the impurities from sticking to treatment pipe 1 5 and affecting its normal filtration.

[0032] By starting the stirring motor 11, its drive shaft can be rotated, which drives the spiral fan blade 12 and the stirring rod 13 to rotate continuously inside the treatment tube 6. When a large amount of rainwater is introduced into the treatment tube 6, the continuous rotation of the stirring rod 13 can agitate the water, preventing impurities from settling inside the treatment tube 6. Furthermore, the continuous rotation of the spiral fan blade 12 can push the water flow towards the rainwater collection tank 1 to increase the water flow rate.

[0033] When there is no water flow introduced into the second treatment pipe 6, the rotation of the spiral fan blade 12 can generate wind to blow the impurities adhering to the first treatment pipe 5, so as to blow off the impurities. When the stirring rod 13 continues to rotate, it will drive the cleaning scraper 14 to rotate against the outer ring of the first treatment pipe 5, so as to scrape off the impurities on the first treatment pipe 5, so as to clean the first treatment pipe 5.

[0034] And in the cleaning, the outer pollution discharge pipe can be connected with the residue discharge pipe below the impurity deposition box 15, and the residue discharge electromagnetic valve 16 is opened, so that the impurities cleaned can be discharged, without manual carrying and disassembly for cleaning, thereby improving the use effect, and the rainwater collection box 1 stores water when it rains, and when the subsequent water amount is small, the stored water can be released and utilized by starting the water pump 3, thereby adapting to environmental changes and coping with natural disasters.

[0035] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to the embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
