[0039] The lower left end of the box body 1 is fixedly connected to the sewage outlet 30, and a valve is installed in the sewage outlet 30. The valve is usually closed and will be opened when the sediment settled at the bottom needs to be discharged.

[0040] The lower right end of the box body 1 is fixedly connected to the water outlet 8, and a first water pump 9 is fixedly installed inside the box body 1. The pump port of the first water pump 9 is connected and communicated with the water outlet 8 for discharging filtered rainwater.

[0041] The directional words described above, such as up, down, left, right, front, and back, are all based on Figure 1 For reference.

[0042] Working principle of embodiment 1:

[0043] In the initial state, the filter screen 18 is located at a position slightly above the bottom of the box body 1 and is lower than the filter hole located at the lowest point on the partition 17. The first slider 14 and the two second sliders 25 are all located at the rear side of the box body 1.

[0044] On rainy days, rainwater flows through the sump 4 to the water grate 5. The large garbage filtered by the water grate 5 is blocked outside the box 1, and the rainwater flows into the box 1 on the left side of the partition 17, and most of the silt in the rainwater will accumulate at the bottom of the left box 1. As the rainwater continues to pour in, the rainwater first floods the filter screen 18, and then slowly begins to flood the filter holes on the partition 17 at the lowest point. At this time, the rainwater enters the right side of the partition 17 through the filter holes on the partition 17 until the water heights on the left and right sides are equal. In this process, the garbage and unsettled silt in the rainwater will be filtered out by the filter holes on the partition 17, so that it is always on the left side of the partition 17.

[0045] When a certain amount of rainwater accumulates in the box body 1, the first water pump 9 can be turned on, and the first water pump 9 discharges the filtered water from the water outlet 8 for storage or use. When draining, the water levels on the left and right sides of the partition 17 begin to drop synchronously until the water level on the left side of the partition 17 is lower than the filter hole on the partition 17 at the lowest point. During this process, the rainwater on the left side of the partition 17 enters the box body 1 on the right side of the partition 17 through the filter hole on the partition 17. Then the water level on the left side of the partition 17 stops dropping, and the water level on the right side of the partition 17 continues to drop as the first water pump 9 continues to work. When the water level drops to a certain height, the first water pump 9 stops working to ensure that there is always enough rainwater in the box body 1 on the right side of the partition 17, so that there is water to pump when the second water pump 10 works.

[0046] Then clean the partition 17 and the filter screen 18. First, start the two first motors 22. The output shafts of the two first motors 22 will drive the winding roller 21 connected to them to rotate. The rotation of the winding roller 21 will drive the two pull ropes 20 on the winding roller 21 to wind up on the winding roller 21. During the winding process, the pull rope 20 will pull the fixing ring 19 upward, and the fixing ring 19 will drive the filter screen 18 to move upward. During the upward movement of the filter screen 18, first, the garbage in the rainwater on the left side of the partition 17 will be filtered out, and second, since the filter screen 18 and the partition 17 are slidably matched, the garbage covering the partition 17 will be scraped off. When the top of the filter screen 18 contacts the bottom of the scraper 29, the two first motors 22 stop working.

[0047] Then, the second motor 23 and the second water pump 10 are started simultaneously. At this time, the output shaft of the second motor 23 drives the first threaded rod 15 and the first pulley to rotate simultaneously.

[0048] When the first threaded rod 15 rotates, the first threaded rod 15 pushes the first slider 14 to move forward along the slide groove 16, the first slider 14 pushes the water spray pipe 12 to move forward, and the water spray pipe 12 drives the nozzle 13 to move forward. Under the operation of the second water pump 10, the rainwater inside the box body 1 on the right side of the partition 17 is sequentially sprayed through the second water pump 10, the hose 11, the water spray pipe 12, and finally from the nozzle 13 to flush the sediment attached to the filter hole on the left side of the partition 17, so that the sediment falls into the box body 1 on the left side of the partition 17 for sedimentation.

[0049] At the same time, the first pulley rotates to drive the belt 24, the belt 24 drives the second pulley to rotate, the second pulley drives the second threaded rod 26 to rotate, the second threaded rod 26 pushes the second slider 25 connected to its own thread to move forward, the second slider 25 drives the connecting plate 27 to move forward, the connecting plate 27 not only drives the scraper 29 to move forward to clean the garbage on the filter 18, but also drives another second slider 25 to slide forward along the guide rod 28. At this time, the pin 3 is pulled out, and the rotating plate 2 is turned to the outside of the box body 1 until the rotating plate 2 is in contact with the box body 1. At this time, the garbage outlet is opened, and the rotating plate 2 is tilted downward to form a slope that is convenient for the garbage to flow out. As the scraper 29 continues to move forward, the garbage gradually flows out of the garbage outlet.

[0050] When the two second sliders 25 contact the front inner wall of the box body 1, the second motor 23 and the second water pump 10 are turned off. At this time, the scraper 29 and the water spray pipe 12 are both located on the front side of the box body 1, and the filter screen 18 and the filter holes on the partition 17 are cleaned.

[0051] During the above process, the scraper 29 and the water spray pipe 12 move forward synchronously.

[0052] After that, as all the silt in the rainwater on the left side of the box body 1 gradually settles at the bottom of the box body 1, the valve in the sewage outlet 30 is opened, and the rainwater with the settled silt is discharged from the sewage outlet 30. After the sewage is discharged, the valve in the sewage outlet 30 is closed. The two first motors 22 and the second motor 23 are started again. The output shafts of the two first motors 22 are reversed, and the pull rope 20 is released. Under the action of the gravity of the fixing ring 19 and the filter screen 18, the filter screen 18 moves down to the initial position, and the two first motors 22 are turned off. At the same time, the output shaft of the second motor 23 is reversed, thereby driving the first threaded rod 15 and the second threaded rod 26 to reverse. At this time, the first slider 14 slides backward along the slide groove 16, and the water spray pipe 12 moves backward to return to the initial position; the second slider 25 slides backward along the guide rod 28, and the second slider 25 drives the connecting plate 27 to slide backward, and the scraper 29 returns to the initial position. Then the second motor 23 is turned off.

[0053] Finally, clean up the garbage on the water grate 5, push the rotating plate 2 to close the garbage outlet, and insert the pin 3.

[0054] Embodiment 2

[0055] like Figures 5 and 6 A sponge city rainwater treatment system is shown, and the difference between this embodiment and the first embodiment is that the first driving unit includes a pull rod 31, and the pull rod 31 horizontally penetrates the box body 1 from the front to the back and slides with the box body 1. The rear end of the pull rod 31 is fixedly connected to the connecting plate 27, and the front end of the pull rod 31 is welded and fixed with a pull block 32, which is convenient for pulling the pull rod 31, and the pull block 32 is located on the outer front side of the box body 1.

[0056] Two guide rods 28 are arranged on the left side of the partition 17. The two guide rods 28 are located at the same vertical height, one on the left and one on the right, and are arranged horizontally in front and back. The two guide rods 28 correspond to the two second sliders 25 one by one. Each guide rod 28 is fixedly connected to the box body 1, and each guide rod 28 passes through the corresponding second slider 25 and slides with the corresponding second slider 25.

[0057] The directional words described above, such as up, down, left, right, front, and back, are all based on Figure 5 For reference.

[0058] Working principle of the second embodiment:

[0059] The difference between this working principle and the first embodiment is that the working driving mode of the first driving unit is different, so this working principle only describes the driving mode, and other principles are the same as the first embodiment.

[0060] When the top of the filter 18 contacts the bottom of the scraper 29, the pull block 32 is pulled forward, the pull block 32 drives the pull rod 31 to move forward, the pull rod 31 drives the connecting plate 27 to move forward, the connecting plate 27 drives the scraper 29 to move forward, and the scraper 29 cleans the garbage on the top of the filter 18.

[0061] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
