The sliding rod 12 is rotatably connected to the rotating rod 11.

[0031] A brush 13 is fixedly connected to the outer wall of the sliding rod 12. The outer wall of the brush 13 is slidably connected to the inner wall of the front end of the water storage tank 4 and the bottom of the filter plate 5, and can be in abutment state.

A flow control component is fixedly connected to the inner wall of the right side of the water storage tank 4. The flow control component is used to control the flow rate of filtered water inside the water storage tank 4.

[0032] Reference Figure 1, Figure 3 , Figure 4 The flow control component includes a pipe 14, which is fixedly connected to the inner right wall of the water storage tank 4, serving as a channel for water flow in the water circulation device. The design of the pipe 14 ensures smooth water flow and effective operation of the flow control component. The outer wall of the brush 13 is slidably connected to the inner rear wall of the housing 6, and the outer wall of the pipe 14 is fixedly connected to the inner right wall of the water storage tank 4. A second motor 15 is fixedly connected to the right side of the water storage tank 4. The second motor 15 provides power to the flow control component, driving the worm gear 17 to rotate, thereby adjusting the position of the flow control disc 20 and controlling the water flow. A housing 16 is fixedly connected to the right side of the second motor 15. The housing 16 protects the internal transmission components such as the worm gear 17 and worm wheel 18, ensuring stable operation of the flow control component. The drive end of motor 215 is fixedly connected to a worm gear 17. The outer wall of the worm gear 17 meshes with the outer wall of the worm wheel 18. The worm wheel 18 meshes with the worm gear 17.

The rubber ring 21 is fixedly connected to the outer wall of the flow control plate 20.

[0034] Working Principle: Rainwater first undergoes preliminary filtration through soil layer 1. Microorganisms and organic matter in soil layer 1 remove some suspended solids and pollutants from the water, providing pre-treated water for subsequent treatment. Rainwater then undergoes secondary filtration through sand and gravel layer 2. Sand and gravel layer 2, composed of sand and gravel of varying sizes, further removes suspended solids and impurities, ensuring water cleanliness. The water is then diverted through collection pipe 3 and filtered again through filter plate 5 before flowing into the storage tank 4. When cleaning of filter plate 5 is needed, or when accumulated impurities need to be removed, motor 7 is activated. Motor 7 provides power to the automatic cleaning system, driving the rotation of drive gear 9 to initiate the automatic cleaning process. Drive gear 9 meshes with driven gear 10; the rotation of drive gear 9 drives driven gear 10 to rotate, thereby driving rotating rod 11 to rotate. The rotation of rotating rod 11 is the key link in the cleaning process, converting the motor's rotational motion into sliding motion. The rotation of the rotating rod 11 causes the sliding rod 12 to slide against the inner wall of the housing 6, so that the brush 13 cleans the bottom surface of the filter plate 5.

[0035] When it is necessary to adjust the flow rate of filtered water inside the water storage tank 4 (that is, to adjust the liquid volume in the water storage tank; if the liquid level in the tank is too high, it needs to be drained in time; if the liquid level is low, it should not be drained or should be drained at a small flow rate to avoid storing too much water that cannot be drained in time, and to avoid storing too little water that will result in a loss of water storage capacity), start motor 2 15. Motor 2 15 is the power source of the flow control component, used to drive the entire flow control system and ensure precise control of the water flow. Motor 2 15 drives the worm gear 17 to rotate. The design of the worm gear 17 allows the high-speed rotation of motor 2 15 to be converted into the low-speed rotation of the flow control plate 20, achieving fine control of the water flow. The rotation of the worm gear 17 transmits the rotational motion to the worm wheel 18 through meshing with the worm wheel 18, which is a key link in the transmission system of the flow control component. The round rod 19 is the bridge connecting the worm wheel 18 and the flow control plate 20; the rotation of the round rod 19 drives the flow control plate 20 at the bottom to rotate. The flow control plate 20 is located inside the pipe 14. By adjusting its position within the pipe 14, the water flow can be controlled, achieving precise control of the filtered water flow rate inside the water storage tank 4. A rubber ring 21 is fixedly connected to the outer wall of the flow control plate 20. The rubber ring 21 is in close contact with the inner wall of the pipe 14, providing a sealing effect.
