By integrating multiple components such as drainage channels, boxes, hydrocyclones, multi-stage filters, filter chambers and water reservoirs, an efficient water purification and storage system is formed. The system can effectively improve the efficiency of water treatment. Through a multi-stage filtration mechanism, it gradually removes pollutants such as suspended matter and impurities in the water body, ensuring that the water quality in the final reservoir meets the use standards. At the same time, the system has a reasonable layout, compact structure, easy maintenance and operation, and is suitable for a variety of water purification scenarios; 2. A branch pipe is set at the sewage end of the hydrocyclone and connected to the first sewage pipe at the bottom of the shell, which realizes the rapid discharge of suspended matter separated in the hydrocyclone.

This structure not only enhances the filtration effect, but also extends the service life of the filter and reduces maintenance costs; 4. The introduction of ultrasonic vibrators, through the way of vibrating rods passing through the holes of the guide plate and setting baffles, regularly vibrates the particles in the filter layer, effectively preventing the blockage and agglomeration of particles, and improving the filtration efficiency and quality. The application of ultrasonic vibrators also promotes the aggregation and sedimentation of tiny suspended matter in the water, further improving the purification capacity of the system; 5. The filter cartridge adopts a closed structure formed by the first end piece, the second end piece and the filter screen, combined with the rotational connection between the first end piece and the shell and the adapter column design of the second end piece, so that the filter cartridge can be cleaned or replaced without interrupting the water flow. This design improves the flexibility and maintenance convenience of the system and ensures the continuous stability of the filtering effect; 6. The second drive member drives the first end plate to rotate, and the backwashing pipe, backwashing cylinder and third drive member in the backwashing assembly realize automatic backwashing of the filter screen in the filter cartridge. The nozzle design on the backwashing pipe enables the high-pressure water flow to be evenly sprayed onto the filter screen, effectively removing impurities and blockages attached to the mesh. This design significantly improves the cleaning efficiency and effect of the filter cartridge and extends the service life of the filter cartridge; 7. The recoil assembly uses a third drive member to drive the piston to move through an eccentric connecting rod, which realizes the intermittent release of the high-pressure water flow in the recoil cylinder. This design not only simplifies the drive mechanism, but also improves the energy conversion efficiency and ensures the stability and reliability of the backwash process. At the same time, the support rod and reinforcement rod design on the adapter column enhance the fixity and stability of the recoil pipe and prevent shaking and damage during the backwash process.

Several fences can be arranged in the drainage channel 1 to intercept larger impurities, such as branches, leaves, stones, mud, plastic, etc. The hydrocyclone 3 utilizes the cyclone effect to separate the large particles and suspended solids in the rainwater before it enters the multi-stage filter 4, thereby improving the overall filtration efficiency and reducing the burden of the subsequent multi-stage filter 4. The hydrocyclone 3 belongs to the prior art and will not be described here. The hydrocyclone 3 includes an inlet end 31, a sewage end 32 and a water outlet end 33.

The medium sand layer is filled with gravel with a particle size between 0.5mm and 1mm, which is used to filter suspended particles with a diameter of 100-300 microns. The fine sand layer is filled with gravel with a particle size between 0.25mm and 0.5mm, which is used to filter suspended particles with a diameter of 50-100 microns. The guide holes are densely opened and the diameter is smaller than the diameter of the gravel in the corresponding filter layer 43. A third pipe 44 is provided at the bottom of the cylinder 41. One end of the third pipe 44 is connected to the cylinder 41, and the other end is connected to the filter chamber 5. The filter chamber 5 includes a shell 51 and a filter cylinder 52.

After the water enters the shell 51, it penetrates into the filter cartridge 52 through the filter screen 523 and flows out through the fourth pipe 542. The other end of the fourth pipe 542 passes through the partition 21 and is connected to the top of the water storage tank 6. A first sewage pipe 512 is arranged at the bottom of the shell 51, and a branch pipe 321 is arranged at the sewage end 32 of the hydrocyclone 3.

When the water body submerges the filter cartridge 52, the water body gradually penetrates the filter mesh 523 to the filter cartridge 52, and enters the water reservoir 6 through the fourth pipe 542. Some impurities are intercepted by the filter mesh 523, or precipitated in the shell 51, and discharged to the outside through the first sewage pipe 512; the water reservoir 6 extracts the purified water body for use through the water intake pipe 62, and the sediment in the water body remains at the bottom of the water reservoir 6 and is discharged to the outside through the second sewage pipe 61.

[0021] Furthermore, since the multi-stage filter 4 relies on particulate matter to filter the water body, during long-term use, impurities are easy to form an accumulation layer on the surface particulate matter, thereby blocking the filter layer 43. However, there is still a large filtration gap in the actual inner layer of particulate matter, which will cause waste. Therefore, in order to make full use of the multi-stage filter 4 and achieve optimal efficiency.
