When it rains, it absorbs water, stores water, penetrates water, purifies water, and releases stored water when needed. It can be used to achieve free migration of rainwater in the city, so it is necessary to collect rainwater.

[0003] After searching, the existing patent (publication number: CN216566567U) discloses a rainwater collection and purification device for a sponge city.

The motor is started to drive the screw rod to rotate, which can drive the pulse jet to move linearly through threaded transmission, thereby cleaning the filter hole inside the collection bin and preventing the filter hole from being blocked to affect the rainwater recovery rate.

[0004] However, the above-mentioned scheme still has certain deficiencies:

[0005] 1. During the cleaning process of the filter, the motor and pulse jet are needed for air jet treatment, which cannot realize self-cleaning of the filter screen, resulting in high cost of the device, and the motor and pulse jet need to be powered, which reduces the applicability of the device and makes it inconvenient to adjust the working position of the device according to actual needs.

The intermittent rotation of the water receiving box can drive the medicine injection mechanism to inject medicine intermittently, so that the collecting frame water storage cavity can add a certain amount of medicine with the increase of a certain amount of rainwater. The automatic cleaning and displacement of the filter screen can add a certain amount of treatment agent to the collected rainwater, which has high use value. BRIEF DESCRIPTION OF DRAWINGS

At this time, the rainwater is first collected by the water receiving box 73 outside the shaft rod 71, and as the rainwater in the water receiving box 73 is rapidly accumulated, the weight of the rainwater rapidly increases. When the rainwater reaches a certain amount, the shaft rod 71 is driven to rotate, so that the water receiving box 73 revolves, and one of the water receiving boxes 73 presses the one end of the pressing rod 841 downward, so that the other end of the pressing rod 841 moves upward, the spring 844 is stretched, the pressing rod 841 supports the push-pull rod 845, the push-pull rod 845 pushes the piston column 831 in the temporary storage cylinder 832 upward, so that the one-way valve 833 at the end of the drainage pipe 835 is opened, and the one-way valve 833 at the end of the suction pipe 834 is closed, so that the liquid in the temporary storage cylinder 832 can be collected into the rainwater collected in the collecting frame 13 through the drainage pipe 835.

[0070] Working principle and use process: when collecting rainwater, add flocculating agent, alum and other sewage treatment liquid into the cartridge 81 in advance, rainwater flows into the inside of the support frame 12 through the rainwater collecting bucket 11, at this time, the rainwater will be collected by the water receiving box 73 outside the shaft rod 71, as the rainwater in the water receiving box 73 accumulates rapidly, the weight of the rainwater increases rapidly, when the rainwater reaches a certain amount, it will drive the shaft rod 71 to rotate, so that the water receiving box 73 revolves, one of the water receiving boxes 73 will press down one end of the pressure rod 841, so that the other end of the pressure rod 841 moves up, the spring 844 is stretched, the pressure rod 841 supports the push-pull rod 845, the push-pull rod 845 pushes the piston column 831 in the temporary storage cylinder 832, so that the one-way valve 833 at one end of the drainage pipe 835 opens, the one-way valve 833 at one end of the suction pipe 834 closes, so that the liquid in the temporary storage cylinder 832 can flow into the rainwater collected in the collecting frame 13. With the continuous revolution of the water receiving box 73, it will be separated from the pressure rod 841, at this moment, the originally stretched spring 844 will pull down the pressure rod 841, so that the pressure rod 841 is restored to the horizontal state on the upper end of the T-shaped rod 843, in this process, the pressure rod 841 pulls down the piston column 831 through the push-pull rod 845, at this time, the one-way valve 833 at one end of the drainage pipe 835 closes, the one-way valve 833 at one end of the suction pipe 834 opens, the liquid in the cartridge 81 is pumped into the temporary storage cylinder 832 for temporary storage through the suction pipe 834, and the next round of liquid addition work continues.

In the process of rotating the second rotating roller 62, the large gear 51 is driven to rotate, the large gear 51 drives the second pinion 53 to rotate through the first pinion 52, and the rotating speed of the first pinion 52 and the second pinion 53 is greater than that of the large gear 51, the first pinion 52 and the second pinion 53 drive two rotating rods 36 to rotate respectively, and the bristles 35 on the rotating rods 36 rub and clean the outer wall of the filter screen 2. At the same time, due to the height of the third rotating roller 64 being lower than that of the second rotating roller 62, the filter screen 2 between the second rotating roller 62 and the third rotating roller 64 is in an inclined state, and the filter screen 2 between the second rotating roller 62 and the third rotating roller 64 is not blocked by the support frame 12 and is in an exposed state, so that the external rainwater can directly wash the upper surface of the filter screen 2, and the filtered rainwater can wash the lower surface of the filter screen 2, which can greatly improve the cleaning strength of the filter screen 2 in combination with the rubbing and cleaning of the cleaning assembly 3.

[0072] With the intermittent collection and accumulation of rainwater inside the storage cavity of the collecting frame 13, the medicine liquid inside the medicine cartridge 81 is added intermittently and quantitatively. When the added medicine liquid is a flocculating agent, the suspended solids in the rainwater inside the storage cavity of the collecting frame 13 continuously precipitate. The collected dirt and filth precipitated from the rainwater can be collected and treated by the dirt collecting box 4 sleeved at the bottom of the collecting frame 13.

[0073] After a long period of work, when it is necessary to disassemble, replace or clean the cleaning assembly 3, one of the connecting rings 37 is removed from the end of the rotating rod 36 by rotating the threaded sleeve 31, and the rotating rod 36 is extracted from the inside of the collecting frame 13 through the other connecting ring 37. When the cleaning assembly 3 is installed, the rotating rod 36 is inserted into the collecting frame 13 through the two through holes 33, and the bristles 35 are bent and then unfolded after passing the inner side of the through hole 33. Then, the threaded sleeve 31 is tightened on the threaded section 34, so that the rotating balls 38 on the two connecting rings 37 are located in the two spherical ring cavities 32 respectively, so that the rotating balls 38 can rotate in the spherical ring cavities 32 when the rotating rod 36 rotates.

[0074] The above is only a preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
