The above-described azimuth terms such as up, down, left, right, front, and rear are all referred to in fig. 1.

The working principle of the first embodiment is as follows:

In the initial state, the filter screen 18 is positioned at a position above the bottom of the case 1 and below the filter holes positioned at the lowest point on the partition 17. The first slider 14 and the two second sliders 25 are both located at the rear side inside the case 1.

In rainy days, rainwater flows to the water grate 5 through the water collecting tank 4, large garbage passing through the filtering part of the water grate 5 is blocked outside the box body 1, the rainwater flows into the box body 1 at the left side of the partition plate 17, and most of sediment in the rainwater can be accumulated at the bottom of the box body 1 at the left side. As the rain water continuously floods, the rain water firstly drops out of the filter screen 18, and then slowly starts to drop out of the filter holes positioned at the lowest point on the partition 17. At this time, rainwater enters the right side of the partition plate 17 through the filtering holes on the partition plate 17 until the water body heights on the left side and the right side are equal, and in the process, garbage and sediment which are not precipitated in the rainwater can be filtered out by the filtering holes on the partition plate 17, so that the garbage and sediment are always on the left side of the partition plate 17.

When a certain amount of rainwater accumulates in the tank 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 so as to be stored or used. The water level on the left and right sides of the partition 17 starts to drop synchronously during drainage until the water level on the left side of the partition 17 is lower than the lowest filtering holes on the partition 17, and in the process, rainwater on the left side of the partition 17 enters the box body 1 on the right side of the partition 17 through the filtering holes on the partition 17. Then the left water level of the partition plate 17 stops descending, the right water level of the partition plate 17 continues descending along with the continuous operation of the first water pump 9, and after the water level of a certain height is reduced, the first water pump 9 stops working, so that enough rainwater is always kept in the box body 1 on the right side of the partition plate 17, and water can be pumped when the second water pump 10 works.

The partition 17 and the screen 18 are then cleaned. Firstly, two first motors 22 are started, output shafts of the two first motors 22 drive winding rollers 21 connected with the two first motors to rotate, and the winding rollers 21 rotate to drive two pull ropes 20 on the winding rollers 21 to wind and roll on the winding rollers 21. In the winding process, the pull rope 20 pulls the fixing ring 19 to move upwards, the fixing ring 19 drives the filter screen 18 to move upwards, in the upward moving process of the filter screen 18, firstly, garbage in rainwater on the left side of the partition 17 is filtered out, and secondly, the filter screen 18 is in sliding fit with the partition 17, so that the garbage covered on the partition 17 is scraped. When the top of the screen 18 contacts the bottom of the scraper 29, the two first motors 22 cease to operate.

After which 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 belt wheel to rotate simultaneously.

When the first threaded rod 15 rotates, the first threaded rod 15 pushes the first sliding block 14 to move forwards along the sliding groove 16, the first sliding block 14 pushes the spray pipe 12 to move forwards, and the spray pipe 12 drives the spray head 13 to move forwards. Under the operation of the second water pump 10, rainwater in the box body 1 on the right side of the partition plate 17 sequentially passes through the second water pump 10, the hose 11, the water spraying pipe 12 and finally is sprayed out from the spray nozzle 13 to wash out sediment attached to the filter holes on the left side of the partition plate 17, so that the sediment falls into the box body 1 on the left side of the partition plate 17 for precipitation.

At the same time, the first belt wheel rotates to drive the belt 24 to rotate, the second belt wheel drives the second threaded rod 26 to rotate, the second threaded rod 26 pushes the second sliding block 25 in threaded connection with the second sliding rod 26 to move forwards, the second sliding block 25 drives the connecting plate 27 to move forwards, and the connecting plate 27 drives the scraping plate 29 to move forwards to clean garbage on the filter screen 18 and simultaneously drives the other second sliding block 25 to slide forwards along the guide rod 28. At this time, the pin 3 is pulled out, so that the rotating plate 2 is turned over to the outside of the box body 1 until the rotating plate 2 is abutted against the box body 1, at this time, the garbage outlet is opened, and the rotating plate 2 is inclined downwards to form a slope which is convenient for discharging garbage. As the scraper 29 moves forward, the waste gradually flows out of the waste outlet.

When the two second sliding blocks 25 are in contact with the inner wall of the front side of the box body 1, the second motor 23 and the second water pump 10 are turned off, and the scraping plate 29 and the water spraying pipe 12 are positioned on the front side of the inside of the box body 1, and the filter screen 18 is cleaned completely, and the filter holes on the partition plate 17 are cleaned completely.

The scraper 29 and the sprinkler pipe 12 move forward in synchronization with each other in the above process.

Then, along with the gradual sediment of all the sediment in the rainwater on the left side of the box body 1 at the bottom of the box body 1, the valve in the sewage outlet 30 is opened, and the rainwater is discharged from the sewage outlet 30 with the sediment. After the sewage is discharged, the valve in the sewage outlet 30 is closed. The two first and second motors 22, 23 are started again. The output shafts of the two first motors 22 are reversed, the pull rope 20 is released, and the filter screen 18 moves back to the initial position under the action of the gravity of the fixing ring 19 and the filter screen 18, and at the moment, the two first motors 22 are turned off. At the same time, the output shaft of the second motor 23 is reversed, so that the first threaded rod 15 and the second threaded rod 26 are driven to rotate reversely, at the moment, the first sliding block 14 slides backwards along the sliding groove 16, the spray pipe 12 moves backwards to the initial position, the second sliding block 25 slides backwards along the guide rod 28, the second sliding block 25 drives the connecting plate 27 to slide backwards, and the scraping plate 29 returns to the initial position. The second motor 23 is then turned off.

Finally, the garbage on the water grating 5 is cleaned, the rotating plate 2 is pushed to seal the garbage outlet, and the pin 3 is inserted.
