[0033] In the embodiment of the utility model, a rotating cylinder 500, a driving mechanism and a vibration assembly are arranged in the drain pipe 200, and the driving mechanism drives the rotating cylinder 500 to rotate. When the rotating cylinder 500 rotates, the push block 603 pushes the first filter 300 to rotate clockwise. After the rotating cylinder 500 continues to rotate, the compression spring 601 pushes the top block 602 to move upward, and the top block 602 pushes the first filter 300 to rotate counterclockwise, thereby causing the first filter 300 to rotate up and down at a certain angle, vibrating the impurities on the first filter 300 to the left side into the collection bucket 400, thereby preventing gravel or other impurities from clogging the first filter 300, thereby improving the filtering effect of the first filter 300 and the drainage efficiency of the drain pipe 200.
[0034] like Figure 2 As shown, in the embodiment of the utility model, the rotating cylinder 500 is provided with a plurality of push blocks 603 arranged along its circumferential direction to intermittently push the first filter screen 300, so that the first filter screen 300 rotates up and down at a certain angle under the action of the compression spring 601 to achieve oscillation.
[0035] like Figure 1 As shown, in the embodiment of the utility model, a guide plate 203 is obliquely arranged above the first filter screen 300 in the drain pipe 200, and the driving mechanism includes an impeller 701 which is rotatably arranged on the high end of the first filter screen 300 and rotates under the action of rainwater scouring, and the impeller 701 is located below the low end of the guide plate 203 and is connected to the rotating cylinder 500 through a transmission assembly.
[0036] In the embodiment of the utility model, under the action of the guide plate 203, the flow rate of rainwater is faster to impact the impeller 701 to rotate, and the impeller 701 then drives the rotating cylinder 500 to rotate through the transmission component, and pushes the first filter 300 through the push block 603.

[0038] In the embodiment of the utility model, the impeller 701 rotates to drive the driving shaft 702 to drive the driving wheel 703 to rotate, and the driving wheel 703 then synchronously drives the driven wheel 705 to rotate through the belt 704, and the driven wheel 705 drives the driven shaft 706 to rotate to realize the rotation of the rotating cylinder 500.
[0039] like Figure 1As shown, in the embodiment of the utility model, an electronic level meter 402 is provided in the collection barrel 400. The electronic level meter 402 can be a rotary paddle level meter. After some sand or other impurities are filtered out by the first filter screen 300, they are discharged into the collection barrel 400 along the slope. During the collection process, the internal collection amount is monitored by the rotary paddle level meter. When the set range is reached, the staff can be reminded to clean the collection barrel 400.
[0040] like Figure 1 As shown, in the embodiment of the utility model, the outer circumferential surface of the collecting barrel 400 is provided with a plurality of groups of water permeable holes, and the bottom of the collecting barrel 400 is fixedly connected with a guide pipe 202, and the tail end of the guide pipe 202 is connected with the drain pipe 200. In the process of collecting sand or other impurities, part of the rainwater will fall into the collecting barrel 400. At this time, the rainwater can be seeped out through the water permeable holes and re-discharged into the drain pipe 200 through the guide pipe 202, which will not affect the drainage quality.
[0041] like Figure 1 As shown, in an embodiment of the utility model, a sewage outlet pipe 201 connected to a collection barrel 400 is opened on the drain pipe 200 at the lower end of the first filter screen 300. During the filtering process through the first filter screen 300, sand or other impurities will flow into the collection barrel 400 along the slope of the sewage outlet pipe 201, and then be collected by the collection barrel 400.
[0042] like Figure 1 As shown, in the embodiment of the utility model, a second filter 800 is arranged above the first filter 300 in the drain pipe 200, and a scraping assembly 900 for cleaning the second filter 800 is provided at the water inlet end of the drain pipe 200. Larger gravel or other impurities are filtered through the first filter 300, and then the scraping assembly 900 cleans the first filter 300 to improve its filtering effect. The scraping assembly 900 can refer to the cleaning part of the first filter mentioned in the existing Chinese patent announcement number CN214246356U, and this embodiment will not be described in detail here.
[0043] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
