The blade I6 is in a 1/4 arc shape and is evenly spaced along the circumference of the rotating shaft 5. After being pressurized by the water collecting bucket 2, the rainwater hits the blade I6, thereby driving the rotation. The shaft 5 rotates; the spiral deflector 7 is fixedly installed on the rotating shaft 5, located in the filter cartridge 3, and the outer edge is tangent to the inner wall of the filter cartridge 3, and the water flow enters the filter cartridge 3 after passing through the blade I6, along the spiral deflector 7 The spiral flows downward, pushes the rotating shaft 5 to rotate, and also provides part of the power for the rotation of the rotating shaft 5. During the rotating process of the spiral deflector 7, the sediment adhering to the filter cartridge 3 is scraped out, and then Under the impact of the water flow, it flows down to the bottom of the filter cartridge, effectively cleans the upper half of the filter cartridge, and scrapes out the sundries attached to the inner wall of the filter cartridge 3, thereby restoring the filtering effect of the filter. At the same time, when the water flow is small, the water flow flows along the spiral deflector 7, and the spiral deflector 7 effectively extends the flow distance of the water in the filter cartridge 3, so that the water can fully contact and filter with the upper half of the filter cartridge 3, forming a The rotating water flow that rotates around the spiral deflector 7 slants and impacts the filter cartridge, which effectively speeds up the filtration efficiency; when the water flow is large, the water flow fills the filter cartridge 3, and the rotating spiral deflector 7 drives the water flow in the filter cartridge 3 to rotate. A rotating water column is formed in the filter cartridge 3, thereby enhancing the impact of the water flow on the wall of the filter cartridge 3 and improving the rainwater filtration capacity.

The rotating shaft 5 is jointly driven to rotate, effectively enhancing the rotational power of the rotating shaft 5, and effectively ensuring that the rotating shaft is evenly driven to rotate in the state of small water flow or large water flow.

In the present invention, the water collecting bucket 2 is covered with a filter mesh 10, and the filter mesh 10 adopts a mesh with a larger aperture to prevent large debris from entering the cylinder body 1 and cause damage to the filter cylinder 3, ensuring that the device safe operation.

In the present invention, the inner wall of the water collecting bucket 2 is provided with guide grooves 11 which are spirally arranged in the same twisting direction as the rotation direction of the blade I6. When the water volume is small, the water flow moves along the guide groove 11 to the bottom end. , forming a water flow that is inclined to the blade I6, so that the water flow obliquely impacts the blade I6. Compared with the direct inflowing water flow, the blade I6 is more impacted, providing greater power for the rotation of the rotating shaft 5; when the water flow is larger At this time, a water flow in the same direction as the rotation direction of the blade I6 is formed in the water collecting bucket 2 through the guide groove 11, which effectively improves the rotation force of the blade I6.
