The plurality of scrapers 32 are all in contact with the outer surface of the filter 35. By setting the fixed frame 33, the connecting column 37, the fan 36 and the scraper 32, the blades on the fan 36 can rotate under the flow of sewage, and the scraper 32 can be driven to scrape the surface of the filter 35.

[0054] Main working principle: When urban sewage passes through the drainage pipe 5, it will enter the sewage collecting box 3. Most of the strip-shaped impurities in the urban sewage will be hooked by the V-shaped rod 28 inclinedly arranged on the bearing plate 27. The space inside the sewage collecting box 3 can be used to store most of the strip-shaped impurities, which will not have much impact on the normal flow of sewage. The driving component can drive the screw rod 20 to rotate. Under the axial limit of the limit component, the collar 22 threadedly sleeved on the outer wall of the screw rod 20 can move upward, and the collar 22 will The clamp ring 21 is driven to move upward, and the clamp ring 21 drives the multiple connecting rods 24 on its outer wall to rotate clockwise at the same time, and the rectangular shells 26 that are rotatably connected to the multiple connecting rods 24 and are respectively sleeved on the multiple supporting plates 27 will slide along the surface of the supporting plate 27. Because the inner diameter of the rectangular shell 26 is larger than the width of the V-shaped rod 28, the rectangular shell 26 can push away the strip impurities hooked by the V-shaped rod 28 when it moves to the edge of the V-shaped rod 28, and the strip impurities will slide along the The inclined extension plate 25 slides on both sides of the interior of the dirt collecting box 3 and falls to the bottom of the dirt collecting box 3, preventing the strip impurities from being hooked by the blades 18 near the center of the dirt collecting box 3. The rotating shaft 17 and the blades 18 can rotate together with the limit plate 23 under the screw rod 20, so that the accumulated impurities can be stirred to facilitate discharge out of the dirt collecting box 3. The impurities can be discharged through the sewage discharge assembly. The filter 35 can filter the impurities in the sewage to prevent the drain pipe 5 from being blocked. Because the sewage has a certain flow rate, the sewage can drive the fan 36 to rotate when passing through the fan 36. The fan 36 can drive the connecting column 37 to rotate on the inner wall of the fixing frame 33. The scraper 32 on the connecting column 37 can continuously scrape the surface of the filter 35 to scrape off the impurities adhered to the surface of the filter 35. After the impurities are scraped off, they can be precipitated inside the dirt collecting box 3, so that the surface of the filter 35 is always kept clean to prevent the filter 35 from being blocked by impurities and affecting its use. The filter 35 can be taken out through the fixing assembly.

[0055] Therefore, the above scheme:

[0056] 1. By setting a bearing plate, a connecting rod, a bearing plate and a V-shaped rod, when urban sewage passes through the drainage pipe, it will enter the sewage collecting box. The bearing plate and the connecting rod can fix the bearing plate and the V-shaped rod in the sewage collecting box. Most of the strip-shaped impurities in the urban sewage will be hooked by the V-shaped rod obliquely set on the bearing plate, and most of the strip-shaped impurities will be collected in the sewage collecting box. The space inside the sewage collecting box can be used to store most of the strip-shaped impurities, which will not have much impact on the normal flow of sewage, and solve the problem that strip-shaped impurities similar to plastic bags can easily cause blockage of drainage pipes in municipal tunnels.

[0057] 2. By arranging a driving assembly, a sewage discharge assembly, a collar, a limit assembly, a snap ring, a connecting rod, a rectangular shell, an extension plate, a rotating shaft and a blade, the driving assembly can drive the screw rod to rotate. Under the axial limit of the limit assembly, the collar threaded on the outer wall of the screw rod can move upward, and the collar will drive the snap ring to move upward, and the snap ring will drive the multiple connecting rods rotatably connected and inclined on its outer wall to rotate clockwise at the same time, and the rectangular shells rotatably connected with the multiple connecting rods and respectively sleeved on the multiple bearing plates will slide along the surface of the bearing plate. The diameter is larger than the width of the V-shaped rod, so when the rectangular shell moves to the edge of the V-shaped rod, the strip-shaped impurities hooked by the V-shaped rod can be pushed off, and the strip-shaped impurities will slide along the inclined extension plates on both sides of the interior of the dirt collecting box and fall to the bottom of the dirt collecting box, thereby preventing the strip-shaped impurities from being hooked by the blades near the center of the dirt collecting box. The rotating shaft and the blades can rotate together with the limit plate under the screw rod, and the accumulated impurities can be stirred to facilitate their discharge out of the dirt collecting box. The impurities can be discharged through the sewage discharge assembly, and the strip-shaped impurities similar to plastic bags are easy to clean.

[0058] 3. By setting the mounting ring, fixing assembly, filter, fixing frame, connecting column, fan and scraper, the filter can first filter the impurities in the sewage to prevent the drain pipe from being blocked. Since the sewage has a certain flow rate, the sewage can drive the fan to rotate when passing through the fan, and the fan can drive the connecting column to rotate on the inner wall of the fixing frame. The scraper on the connecting column can continuously scrape the surface of the filter to remove the impurities adhering to the surface of the filter. After the impurities are scraped off, they can be precipitated inside the sewage collecting box to ensure that the surface of the filter is always clean, avoiding the filter being blocked by impurities and affecting its use. The filter can be taken out through the fixing assembly, and the drain pipe is not easily blocked by impurities.
