Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Refer to Figure 1 And Figure 2 As shown in the figures, an embodiment provided by the present invention: an impurity removal and sampling device for urban sewage samples, including a sampling bucket 1, a cover plate 2 is fixedly connected to the top of the sampling bucket 1, an exhaust hole 3 is fixedly connected to the left end of the cover plate 2, water inlet pipes 4 are fixedly connected to both the front and rear sides of the sampling bucket 1, spheres 5 are fixedly connected to the opposite ends of the water inlet pipes 4, a plurality of water inlet holes 6 are arranged on the outer sides of the spheres 5, baffles 7 are fixedly connected to the inner walls of the sampling bucket 1 at positions corresponding to the water inlet pipes 4, a water outlet pipe 8 is fixedly connected to the bottom of the front side of the sampling bucket 1, and a valve 9 is fixedly connected to the middle of the water outlet pipe 8;

[0025] Immerse the lower end of the sampling bucket 1 in the sewage. The sewage enters the sphere 5 through the water inlet hole 6 and is collected in the sampling bucket 1 through the water inlet pipe 4. By setting the sphere 5 and the water inlet hole 6, the collection of impurities can be avoided, facilitating the subsequent detection of sewage. By setting the water outlet pipe 8 and the valve 9, the sewage in the sampling bucket 1 can be conveniently discharged.

[0026] Refer to Figure 2 And Figure 3 As shown in the figures, a protective cover 10 is fixedly connected to the middle of the lower side of the cover plate 2. Connecting rods 11 are rotatably connected to both the front and rear sides of the protective cover 10. First bevel gears 12 are fixedly connected to the opposite ends of the connecting rods 11. Scrapers 13 are fixedly connected to the opposite ends of the connecting rods 11. The inner walls of the scrapers 13 are closely fitted with the outer walls of the spheres 5. A first U-shaped plate 14 is fixedly connected to the upper side of the cover plate 2. A motor 15 is fixedly connected to the upper side of the first U-shaped plate 14. A rotating shaft 16 is fixedly connected to the output end of the motor 15. The lower end of the rotating shaft 16 penetrates through the middle of the cover plate 2 and is fixedly connected to a second bevel gear 17. The second bevel gear 17 is meshed and connected to the outside of the first bevel gear 12;

[0027] The starting motor 15 drives the rotating shaft 16 to rotate, drives the second bevel gear 17 to rotate through the rotating shaft 16, and thus cooperates with the second bevel gear 17 and the first bevel gear 12 to drive the connecting rod 11 and the scraper 13 to rotate. The outer wall impurities of the sphere 5 are cleaned by the provided scraper 13, so as to avoid the blockage of the water inlet hole 6 by impurities and affect the subsequent collection of sewage.

[0028] Refer to Figure 4 , the outer side of the first U-shaped plate 14 is rotatably connected with a second U-shaped plate 18. An expansion rod 19 is arranged above the cover plate 2. The left end of the expansion rod 19 is fixedly connected with a fixed block 20. An opening 21 is opened at the lower end of the fixed block 20. The inner wall of the opening 21 is tightly fitted with the top outer wall of the second U-shaped plate 18. A fastener 22 is threadedly connected to the lower side of the fixed block 20;

[0029] The provided expansion rod 19 can be telescoped, which can drive the sampling bucket 1 to move, facilitating the collection of sewage from a distance. Through the cooperation of the provided fastener 22 and the fixed block 20, the expansion rod 19 can be fixed at the upper end of the second U-shaped plate 18, thus facilitating the installation and disassembly of the expansion rod 19 and the storage of the device.

[0030] Working principle: The expansion rod 19 is telescoped, and thus the sampling bucket 1 is driven to move by the fixed block 20 and move far away, facilitating the collection of sewage from a distance. The sampling bucket 1 is immersed in the sewage. The sewage passes through the water inlet hole 6 and enters the inside of the sphere 5, and flows into the inside of the sampling bucket 1 through the water inlet pipe 4 to collect the sewage. The starting motor 15 drives the rotating shaft 16 to rotate, thus driving the second bevel gear 17 to rotate. The rotating second bevel gear 17 cooperates with the first bevel gear 12 to drive the connecting rod 11 to rotate, thus driving the scraper 13 to rotate. The outer wall of the sphere 5 is cleaned by the scraper 13, so as to avoid the blockage of the water inlet hole 6 by impurities. The sewage in the sampling bucket 1 is discharged through the provided valve 9 and the water outlet pipe 8.
