The water receiving ball 65 is in the shape of a hollow hemisphere, and the total length of the connecting rod 64 and the water receiving ball 65 is less than the radius length of the sewer pipe 1.

The outer wall of the protrusion 611 is rotatably connected to a moving rod 612. The end of the moving rod 612 away from the protrusion 611 is hinged with a moving block 613.

A sliding groove 616 is provided on the inner wall of the push block 615. The inner wall of the sliding groove 616 is slidably connected to the end of the sliding rod 614 away from the moving block 613.

[0037] Reference Figure 2 , Figure 5 and Figure 6 A connecting assembly is provided on the outside of the anti-blocking tube 2, and the connecting assembly includes an air pressure tube 71. The inner outer wall of the air pressure tube 71 is fixedly connected to the outer wall of the anti-blocking tube 2. The insides of the anti-blocking tube 2 and the anti-blocking tube 8 are both provided with connecting grooves 72. The outer side of the connecting groove 72 is slightly smaller than the inner side. The inner wall of the connecting groove 72 of the anti-blocking tube 2 is fixedly connected with an air bag 73. The material of the air bag 73 is rubber. The air bag 73 is connected to the inside of the air pressure tube 71. The inner wall of the air pressure tube 71 is slidably connected with a slider 74. The end of the slider 74 close to the air pressure tube 71 is elastically connected to the inner wall of the air pressure tube 71 through a spring 75. A control ring 76 is slidably arranged on the outer wall of the anti-blocking tube 2, and a mounting groove 77 is provided at one end of the control ring 76 close to the air pressure tube 71. A plug rod 78 is slidably connected to the outer wall of the control ring 76, and the plug rod 78 penetrates the outer wall of the control ring 76. A plug hole 79 is provided on the outer wall of the air pressure tube 71. The number of the plug rods 78 and the plug hole 79 are consistent and their shapes match. The anti-blocking tube 2 is detachably connected to the anti-blocking tube 2 8 through a connecting assembly. The anti-blocking tube 2 8 is mirror-imaged with the anti-blocking tube 2. The mirror-image setting ensures that a complete pipeline can be formed after the anti-blocking tube 2 is connected to the anti-blocking tube 2 8, thereby ensuring the normal operation of the equipment.

[0038] Working principle: When in use, after the sewage in the sewer pipe 1 enters the water receiving ball 65, the water enters the water receiving ball 65 with the opening upward, so that the gravity of the water receiving ball 65 after receiving water is greater than the gravity of the water receiving ball 65 without receiving water, so that the water receiving ball 65 after receiving water moves downward, and drives the rotating rod 1 61 to rotate during the movement, so that the rotating rod 1 61 drives the turntable 1 66 to rotate, and drives the belt rotating rod 68 to rotate with the turntable 1 66 through the turntable 1 66, so that the belt rotating rod 68 drives the turntable 2 67 to rotate during the rotation, and drives the belt rotating rod 68 to rotate through the turntable 2 67, so that the turntable 3 63 is driven by the conveyor belt 69 and the turntable 2 62 rotates.

[0039] When the rotating rod 3 63 rotates, the elliptical plate 610 rotates, so that the height of the protrusion 611 changes during the rotation of the elliptical plate 610, so that the top height of the moving rod 612 changes, so that the moving rod 612 drives the moving block 613 to move up and down during the movement. When the moving block 613 moves upward, the moving block 613 first moves upward by itself, and drives the sliding rod 614 to move upward during the upward movement. When the sliding rod 614 moves to contact the upper surface of the sliding groove 616, the sliding rod 614 drives the pushing block 615 to move upward, thereby ensuring that when the pushing block 615 and the moving block 613 move upward, a gap can be generated between the moving block 613 and the pushing block 615, so that impurities and part of the water can move to the area below the pushing block 615 through the gap. When the moving block 613 moves downward, the moving block 613 moves upward. Block 613 first moves downward by itself under the drive of moving rod 612. When moving block 613 and pushing block 615 are completely fitted together, moving block 613 drives pushing block 615 to move downward, thereby ensuring that when moving block 613 and pushing block 615 move downward, objects in the area below moving block 613 and pushing block 615 cannot move upward through the plane jointly determined by moving block 613 and pushing block 615. Impurities in the area below moving block 613 and pushing block 615 can be deformed due to the effect of pressure, or impurities with softer materials can enter drainage bin 3 through drainage hole 4, thereby making the impurities smaller, ensuring that blockage is not easy to occur in the subsequent flow process, and the water absorbed by larger impurities can be squeezed by moving block 613 and pushing block 615 to make the water leave the impurities, ensuring that the volume of the impurities is reduced, thereby reducing the blockage area.

[0040] When a lot of impurities have accumulated in the common area of ​​the anti-blocking tube 1 2 and the anti-blocking tube 2 8 and cannot be cleaned automatically, the staff first pulls the plug rod 78 outward to make the plug rod 78 leave the insertion hole 79. At this time, the control ring 76 is not restricted, and the staff slides the control ring 76. When the control ring 76 leaves the range of the anti-blocking tube 1 2, the slider 74 is not squeezed, so the slider 74 moves outward under the action of the spring 75, thereby increasing the area inside the air pressure tube 71, thereby reducing the pressure inside the air pressure tube 71, so that the gas inside the airbag 73 can be attracted to the inside of the air pressure tube 71 under the action of the air pressure. At this time, the airbag 73 is in a contracted state, and the staff can easily remove the anti-blocking tube 2 8, thereby cleaning the anti-blocking tube 1 2 and the anti-blocking tube 2 8. The interior is cleaned. When the cleaning is completed, the staff first fits the anti-blocking tube 2 8 with the anti-blocking tube 1 2, and then slides the control ring 76 to move the control ring 76 in the direction close to the air pressure tube 71, and squeezes the slider 74 through the inner wall of the mounting groove 77. When the slider 74 is squeezed, the slider 74 enters the air pressure tube 71, thereby increasing the pressure inside the air pressure tube 71, and the gas inside the air pressure tube 71 enters the air bag 73 through the pressure, thereby expanding the air bag 73, and after expansion, it enters the connecting groove 72 opened in the anti-blocking tube 2 8, so that the anti-blocking tube 1 2 and the anti-blocking tube 2 8 are tightly fitted and not easy to leak. At this time, the staff pushes the plug rod 78 to make the plug rod 78 enter the socket 79, thereby limiting the control ring 76 to ensure that the fixed state remains unchanged.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
