[0002] In sponge cities, rainwater collection and filtration are crucial. Improving rainwater collection efficiency and avoiding clogging and reducing cleaning frequency are key issues. Current rainwater collection systems use fixed filters to filter impurities from rainwater. The filters need to be cleaned when clogged, but automatic cleaning is not possible, increasing the workload for personnel and making the operation complex and difficult to implement. Utility Model Content

[0003] To overcome the shortcomings of the existing technology, this utility model provides a centrifugal rainwater collection filter, which effectively solves the problem that the support device cannot be used interchangeably when grinding due to different specifications and sizes of the chassis panel.

[0004] The technical solution to the technical problem is: a centrifugal rainwater collection filter, including a body, an inlet on one side of the upper end of the body, an outlet on one side of the lower end of the body, a filter cylinder inside the body, a cleaning component inside the filter cylinder, and a rotating plate inside the cleaning component, with multiple spiral blades inside the rotating plate. The filter cartridge has multiple columns inside, each with a guide groove. The top of the column has an annular groove that communicates with the guide groove. The outside of the rotating plate has a slider that can be inserted into the guide groove or the annular groove. When the slider is in the guide groove, the rotating plate cannot rotate; when the slider is in the annular groove, the rotating plate can rotate.

[0005] Preferably, the machine body is provided with a baffle at the upper end of the filter cylinder, and an outlet is opened at the lower end of the baffle so that rainwater falls into the filter cylinder from the outlet.

[0006] Preferably, the filter cartridge is densely covered with filter holes.

[0007] Preferably, the cleaning assembly includes multiple fixing plates connected by an arc plate. The fixing plates are located between the column and the inner wall of the filter cylinder. Brush bristles extend from the outer side of the fixing plates. A scraper is provided at one end of the outer side of the fixing plates.

[0014] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0015] Depend on Figures 1 to 5 It is known that a centrifugal rainwater collection filter includes a body 1, an inlet 2 on one side of the upper end of the body 1, an outlet 3 on one side of the lower end of the body 1, a filter cylinder 4 inside the body 1, a cleaning component inside the filter cylinder 4, a rotating plate 5 located inside the cleaning component inside the body 1, and multiple spiral blades 6 inside the rotating plate 5. The filter cartridge 4 has multiple columns 7 inside, each column 7 has a guide groove 8, and the top of the column 7 has an annular groove 9 that communicates with the guide groove 8. The outer side of the rotating plate 5 has a slider 10 that is inserted into the guide groove 8 or the annular groove 9. When the slider 10 is in the guide groove 8, the rotating plate 5 cannot rotate, and when the slider 10 is in the annular groove 9, the rotating plate 5 can rotate.

[0016] In practical use, this utility model When this filter is installed in a rainwater harvesting system, rainwater enters the body 1 through the inlet 2. The rainwater first passes through the rotating plate 5. When the rainwater accumulation inside the body 1 is small and the rotating plate 5 is at a low position, the slider 10 is in the guide groove 8, which prevents the rotating plate 5 from rotating. The rainwater will generate a centrifugal effect through the spiral blades 6 inside the rotating plate 5, and will be dispersed and flow towards the inner wall of the filter cylinder 4. After being filtered by the filter cylinder 4, it will be discharged from the outlet 3.

[0017] When a certain amount of rainwater or impurities accumulate inside the filter cylinder 4, the position of the rotating plate 5 rises, causing the slider 10 to move into the annular groove 9. At this time, the rainwater will push the rotating plate 5 to rotate through the rotating plate 5, and the rotating plate 5 will push the cleaning component to rotate. The cleaning component cleans the inner wall of the filter cylinder 4, so that the rainwater is quickly filtered and discharged, causing the water level inside the machine body 1 to drop.

[0018] The body 1 is equipped with a baffle 11 located at the upper end of the filter cylinder 4. The lower end of the baffle 11 has an outlet. Rainwater falls into the filter cylinder 4 from the outlet. The baffle 11 forms a conical structure, which accelerates the flow rate of the rainwater, thereby enabling the rainwater to drive the rotating plate 5 to rotate.

[0019] The filter cartridge 4 is densely covered with filter holes 12, which are used to filter impurities in rainwater.

[0020] The cleaning assembly includes multiple fixing plates 13, which are connected by an arc plate 14. The fixing plates 13 are located between the column 7 and the inner wall of the filter cylinder 4. Brush bristles 15 extend from the outer side of the fixing plates 13. A scraper 16 is provided at one end of the outer side of the fixing plates 13. A limiting block 17 is provided on the inner side of the fixing plates 13 and inserted into the annular groove 9.

[0021] When the outer slider 10 of the rotating plate 5 is located in the annular groove 9, rainwater washes the rotating plate 5, causing it to rotate. When the outer slider 10 of the rotating plate 5 rotates, it pushes the limiting block 17, causing multiple fixed plates 13 to rotate synchronously, cleaning the filter holes 12 of the filter cylinder 4. The ends of the brush bristles 15 can extend into the filter holes 12, and can clean the filter holes 12 when rotating. The scraper 16 is made of flexible material and contacts the inner wall of the filter cylinder 4 to scrape off the deposits on the inner wall of the filter cylinder 4, thereby maintaining the filtration capacity of the filter cylinder 4.

[0022] In this device, the rotating plate 5 is made of lightweight material and can float in rainwater, so that the slider 10 moves upward in the guide groove 8 and enters the annular groove 9, thereby realizing the structure in which rainwater drives its rotation.

[0023] Compared with the prior art, this utility model has the following advantages: it can automatically clean the filter cartridge, maintain the filtration capacity to the greatest extent possible, reduce the frequency of cleaning, and reduce maintenance costs.
