When the control valve 102 is opened, the filtered rainwater is discharged from the drain pipe.

[0024] A plurality of water inlet pipes 9 are connected to one side of the pretreatment box 3, and the other ends of the plurality of water inlet pipes 9 are connected together with a water inlet trough 10. Rainwater on the roof falls into the water inlet trough 10 and then flows into the pretreatment box 3 through the water inlet pipe 9. A hollow plate 11 for supporting the secondary filter 7 is welded between the inner walls of the multiple sides of the secondary treatment box 2. The secondary filter 7 is set on the hollow plate 11. A plurality of hollow rods 13 are slidably connected to the top of the water collecting box 1. A float 14 is fixed to the bottom end of the hollow rod 13. An upper button 16 is fixed to the top between the plurality of hollow rods 13. The outer wall of the hollow rod 13 is provided with a plurality of scale grooves 15. The top of the water collecting box 1 is snapped with a transparent shell 12, the hollow rod 13 is slidably plugged into the top of the transparent shell 12, and the float 14 drives the hollow rod 13 to move up and down as the rainwater level in the water collecting tank 1 rises and falls, and then the collection level of rainwater in the water collecting tank 1 can be understood through the scale groove 15.

[0025] The working principle of this embodiment is as follows: When rainwater is collected, rainwater from the roof falls into the water inlet trough 10, then flows into the pre-treatment tank 3 through the water inlet pipe 9. Then, it passes through the primary filter 6 to filter out large debris in the rainwater. After filtering out large debris, it is input into the secondary treatment tank 2 through the upper water pipe 4. Then, it passes through the secondary filter 7 to filter out larger debris. After filtering out larger debris, it is input into the water collection tank 1 through the lower water pipe 5. Then, it passes through the tertiary filter 8 to filter out smaller debris in the rainwater. Finally, the control valve 102 is opened and the rainwater is discharged from the drain pipe.

[0026] Then, the float bladder 14 moves up and down as the liquid level of the rainwater in the water collecting tank 1 rises and falls, thereby driving the hollow rod 13 to move up and down, and then the collected liquid level of the rainwater in the water collecting tank 1 can be understood through the scale groove 15.
