The inner peripheral wall of the mounting ring 9 is fixedly connected with an extrusion ring 17 located at the bottom of the threaded ring 18, a clamping hole 15 is opened inside the fixing ring 14, and the inner peripheral wall of the mounting ring 9 is fixedly connected with four connecting chambers 16, and an extrusion rod 13 is arranged inside the connecting chamber 16, and the extrusion rod 13 runs through the interior of the mounting ring 9 and the connecting chamber 16, and the outside of the extrusion rod 13 is fixedly connected with a limit plate 12, and the outside of the extrusion rod 13 is provided with a spring 11, and the spring 11 is arranged between the limit plate 12 and the inner left side of the connecting chamber 16, and a cleaning component is arranged on the left part of the sewage pump body 1;

[0025] By inserting the fixing ring 14 into the mounting ring 9 and then rotating the fixing chamber 7, the threaded ring 18 is rotated, and the fixing chamber 7 can be threadedly connected with the thread groove 10 through the threaded ring 18 and move downward, thereby driving the extrusion ring 17 to move downward, so that the extrusion ring 17 squeezes the four extrusion rods 13, and then the four extrusion rods 13 move toward the connecting chamber 16, and further move the four extrusion rods 13 toward the side close to the fixing ring 14, and at the same time, the four springs 11 are compressed until the four extrusion rods 13 are respectively inserted into the four clamping holes 15 for fixing. When the sewage pump body 1 needs to be disassembled, it is only necessary to rotate the fixing chamber 7 in the opposite direction so that the extrusion ring 17 no longer squeezes the extrusion rod 13, and the extrusion rod 13 is no longer inserted into the clamping hole 15 by the tension of the spring 11, and then the sewage pump body 1 is pulled out, and at the same time, the flange on the right part of the sewage pump body 1 is disassembled by removing the fixing bolts and nuts, so as to facilitate the maintenance and replacement of the sewage pump body 1.

[0026] Reference Figure 1 and Figure 3 The cleaning assembly includes a filter box 8, which is fixedly connected to the left part of the sewage pump body 1. A fixed frame 19 is arranged inside the filter box 8, and a filter screen 22 is arranged inside the fixed frame 19. Two slide bars 25 are fixedly connected to the left part of the fixed frame 19, and a brush plate 23 is arranged outside the slide bar 25. A pull rod 24 is fixedly connected to the upper part of the brush plate 23, and the pull rod 24 passes through the upper part of the filter box 8. A collection box 20 is fixedly connected to the lower part of the filter box 8;

[0027] When there are too many impurities on the surface of the filter screen 22, the pull rod 24 is pulled up and down, and the pull rod 24 drives the brush plate 23 to slide outside the sliding rod 25 on the left side of the fixed frame 19, so that the brush plate 23 scrapes the filter screen 22 and collects the impurities in the collection box 20 at the bottom for centralized treatment, which is convenient for subsequent cleaning and processing and ensures the quality of the water flow.

[0028] Reference Figure 1 , Figure 2 and Figure 3 , the brush plate 23 is slidably connected to the outside of the slide rod 25, the extrusion rod 13 is slidably connected to the inside of the clamping hole 15, the upper part of the collection box 20 is fixedly connected with the L-shaped plate 21, the threaded ring 18 is threadedly connected to the inside of the thread groove 10, the left part of the filter box 8 is fixedly connected with the water outlet 2, and the brush plate 23 is slidably connected to the left side of the filter screen 22;

[0029] By sliding the brush plate 23 on the outside of the slide rod 25, the brush plate 23 can be driven to slide on the outside of the slide rod 25 on the left side of the fixed frame 19, so that the brush plate 23 scrapes the filter screen 22; by sliding the extrusion rod 13 inside the clamping hole 15, the sewage pump body 1 can be fixed on the base 5; by setting the L-shaped plate 21, a certain shielding effect can be played on the water flow; by the threaded connection of the threaded ring 18 to the internal thread of the thread groove 10, the fixed bin 7 can be moved downward; by setting the water outlet 2, the device can be transported and discharged; by sliding the brush plate 23 on the left side of the filter screen 22, the brush plate 23 can be driven to scrape the filter screen 22, and the impurities are concentrated in the collection box 20 at the bottom for treatment.

[0030] Working principle: When the device is used, when the sewage pump body 1 needs to be installed, the fixing ring 14 is inserted into the installation ring 9, and then the fixing chamber 7 is rotated to rotate the threaded ring 18, so that the fixing chamber 7 can be threadedly connected with the thread groove 10 through the threaded ring 18 and move downward, thereby driving the extrusion ring 17 to move downward, so that the extrusion ring 17 squeezes the four extrusion rods 13, and then the four extrusion rods 13 move toward the connecting chamber 16, and further move the four extrusion rods 13 toward the side close to the fixing ring 14, and at the same time the four springs 11 are compressed until the four extrusion rods 13 are respectively inserted into the four clamping holes 15 for fixing. When the pump body 1 needs to be disassembled, it is only necessary to rotate the fixed bin 7 in the opposite direction so that the extrusion ring 17 no longer squeezes the extrusion rod 13, and the extrusion rod 13 is no longer inserted into the clamping hole 15 due to the tension of the spring 11. Then the sewage pump body 1 is pulled out, and the sewage pump body 1 is started by starting the motor 3. The water flows into the filter box 8 through the water inlet for filtration and is discharged from the water outlet 2. When there are too many impurities on the surface of the filter screen 22, the pull rod 24 is pulled up and down, and the pull rod 24 drives the brush plate 23 to slide outside the sliding rod 25 on the left side of the fixed frame 19, so that the brush plate 23 scrapes the filter screen 22 and collects the impurities in the collection box 20 at the bottom for centralized treatment.
