[0002] As the global water shortage problem becomes increasingly severe, rainwater, as a recyclable freshwater resource, is being recycled and reused as an important means to alleviate urban water resource pressure and reduce the risk of urban flooding.

[0003] Traditional devices often use filters to filter rainwater. However, the trapped mud, sand, fallen leaves, and other impurities tend to adhere to the filter surface, clogging the filter pores and preventing subsequent rainwater from passing through, thus rendering the purification function ineffective. Furthermore, once the filter is clogged, it needs to be manually disassembled and cleaned, which involves multiple steps such as disassembly, rinsing, and reassembly, making it quite time-consuming. Therefore, a rainwater collection, purification, and utilization device is proposed to solve the problems mentioned above. Utility Model Content

In addition, after the filter screen is blocked, it needs to be manually disassembled and cleaned.

[0014] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0015] Reference Figures 1-8 As shown, a rainwater collection, purification, and utilization device includes a filter box 1. A filter screen mounting groove 4 is provided at the upper end of the filter box 1. A filter tube mounting groove 5 is provided through the bottom inner side of the filter screen mounting groove 4. A top plate 2 is fixedly connected to the upper end of the filter box 1. A first liquid inlet 201 is provided through the upper end of the top plate 2. A rainwater collection hopper 3 is fixedly connected to the upper end of the top plate 2. A second liquid inlet 301 is provided through the upper end of the rainwater collection hopper 3. A filter tube 6 is fixedly connected to the lower end of the top plate 2. The filter tube 6 is fixedly connected to the inner side of the filter tube mounting groove 5. A filter screen rotation groove 7 is provided on the outer surface of the filter tube 6. An impurity discharge groove 8 is provided at the upper end of the filter screen rotation groove 7. The inner side of the filter screen mounting groove 4 rotates... A filter screen 9 is connected to the filter tube 6. A fixing block 10 is fixedly connected to the outer surface of the filter tube 6. A rotating shaft 11 is rotatably connected to the inner side of the fixing block 10. The lower end of the rotating shaft 11 is fixedly connected to the upper end of the filter screen 9. An inner retaining ring 12 is fixedly connected to the center of the upper end of the filter screen 9. The inner retaining ring 12 is fixedly connected to the outer surface of the rotating shaft 11. An outer retaining ring 13 is fixedly connected to the inside of the impurity discharge groove 8. The upper and lower ends of the filter screen 9 are slidably connected to the lower end of the outer retaining ring 13 and the bottom end of the filter screen rotating groove 7, respectively. An impurity discharge outlet 21 is opened at the front end of the filter box 1. An electric push rod 22 is fixedly installed on the inner wall of the filter screen mounting groove 4. A scraper 23 is fixedly connected to the output end of the electric push rod 22.

[0016] Furthermore, the inner wall of the rainwater collection hopper 3 is conical. The rainwater collection hopper 3 is used to expand the rainwater receiving area, guide the rainwater to converge and flow into the filter pipe 6 through the second liquid inlet 301 and the first liquid inlet 201. After entering the filter pipe 6, the rainwater will be filtered through the filter screen 9. The impurities carried by the rainwater are trapped at the upper end of the filter screen 9, and the filtered rainwater leaks out from the lower end of the filter pipe 6 through the pores of the filter screen 9.

[0017] Furthermore, the inner baffle ring 12 and the outer baffle ring 13 are used to prevent impurities on the filter screen from moving toward the non-impurity discharge port 21, and guide the impurities to concentrate and be discharged from the channel and the impurity discharge port 21.

[0018] Furthermore, a fixed base 16 is fixedly connected to the lower end of the top plate 2. A motor 17 is fixedly installed on the inner bottom end of the fixed base 16. The output end of the motor 17 passes through the inner bottom end of the fixed base 16 and is fixedly connected to a drive shaft 18. A first synchronous pulley 15 is fixedly connected to the outer surface of the rotating shaft 11. A second synchronous pulley 19 is fixedly connected to the outer surface of the drive shaft 18. A transmission belt 20 is sleeved on the outer surfaces of the second synchronous pulley 19 and the first synchronous pulley 15.

[0019] Furthermore, when the motor 17 drives the drive shaft 18 and the second synchronous pulley 19 to rotate, the second synchronous pulley 19 will drive the first synchronous pulley 15 to rotate synchronously with the shaft 11 through the transmission belt 20. When the shaft 11 rotates, it will drive the inner retaining ring 12 and the filter screen 9 to rotate. At this time, the impurities on the filter screen 9 located in the filter tube 6 will rotate together with the filter screen 9 and be sent out from the impurity discharge groove 8.

[0020] Furthermore, the lower end of the scraper 23 is in close contact with the upper end of the filter screen 9, and the impurity discharge port 21 is directly opposite the scraper 23.

[0021] Furthermore, the impurity discharge port 21 is used to discharge the impurities scraped off by the scraper 23. When the impurities on the filter screen 9 are sent out from the impurity discharge trough 8, the scraper 23 is driven by the electric push rod 22 to move horizontally along the surface of the filter screen 9, which can scrape off the impurities on the filter screen 9 and push them to the impurity discharge port 21, thereby realizing automated impurity cleaning.

[0022] Furthermore, a guide block 14 is fixedly connected inside the filter tube 6 above the outer baffle ring 13. The inner diameter of the guide block 14 decreases from top to bottom. The guide block 14 is used to guide the rainwater flowing in from the first liquid inlet 201 into the area enclosed by the inner baffle ring 12 and the outer baffle ring 13.

[0023] Furthermore, the lower end of the filter pipe 6 is connected to a water collection tank, and the impurity discharge port 21 is connected to an external impurity collection box.

[0024] Working principle: During rainfall, rainwater falls into the rain collection hopper 3, and is collected by the conical inner wall of the rain collection hopper 3 to the second inlet 301. Then, it flows into the filter pipe 6 through the first inlet 201. The rainwater flowing into the filter pipe 6 is guided by the guide block 14 and then flows precisely into the area enclosed by the inner baffle ring 12 and the outer baffle ring 13 and is filtered by the filter screen 9. When the rainwater passes through the filter screen 9, impurities such as mud, sand, and leaf fragments are trapped at the upper end of the filter screen 9. The filtered rainwater flows through the mesh of the filter screen 9 to the bottom of the filter pipe 6 and is finally sent into the water collection tank. As filtration continues, impurities gradually accumulate on the surface of the filter screen. At this time, the motor 17 starts periodically, driving the drive shaft 18 and the second synchronous belt. When wheel 19 rotates, the second synchronous pulley 19 drives the first synchronous pulley 15 and the rotating shaft 11 to rotate synchronously through the transmission belt 20. This causes the rotating shaft 11 to drive the filter screen 9 and the inner retaining ring 12 to rotate synchronously. At this time, the impurities constrained by the inner retaining ring 12 and the outer retaining ring 13 move synchronously with the filter screen until the impurities are transported to the impurity discharge trough 8. When the impurities move to the impurity discharge trough 8, the electric push rod 22 is activated. Its output end pushes the scraper 23 to move horizontally along the surface of the filter screen 9. The scraper 23 scrapes off the impurities on the surface of the filter screen and pushes the impurities to the impurity discharge outlet 21. The impurities enter the external impurity collection box through the impurity discharge outlet 21, completing the automatic impurity cleaning. After cleaning, the electric push rod 22 drives the scraper 23 to reset.
