The second drive motor 10 and the PLC controller are both existing structures and are not described in detail here. By setting the second drive motor 10, the drive shaft of the second drive motor 10 rotates to drive the stirring column 5 to rotate, and the stirring column 5 rotates to stir the sediment on the bottom of the water to prevent the sediment from accumulating on the bottom of the water, thereby making it easier to absorb the sediment in the sewage. A support frame 4 is fixedly installed on the side, and a first drive motor 8 is fixedly installed on the top surface of the support frame 4. A circular through hole is opened on the top surface of the support frame 4, and the outer cylindrical wall surface of the drive shaft of the first drive motor 8 is movably connected with the inner cylindrical wall surface of the circular through hole. The first drive motor 8 is an existing structure and is not described here.

The outer cylindrical wall surface of the screw rod 17 is threadedly connected with the inner cylindrical wall surface of the threaded hole 18. Through the setting of the first drive motor 8, the rotation of the drive shaft of the first drive motor 8 drives the screw rod 17 to rotate, and the rotation of the screw rod 17 causes the movable plate 12 to move downward along the screw rod 17. The downward movement of the movable plate 12 drives the stirring column 5 to move downward deep into the sewage, thereby adjusting the position of the stirring column 5 according to the depth of the sewage.

[0027] Embodiment 3

[0028] Based on the above embodiment 1 or 2, refer to Figure 1 , Figure 2 , Figure 3 and Figure 4A limiting rod 19 is fixedly installed inside the support frame 4, and a circular through hole is provided on the top surface of the movable plate 12. The outer circular wall surface of the limiting rod 19 is movably connected with the inner circular wall surface of the circular through hole. Through the set movable plate 12, the movable plate 12 moves downward along the limiting rod 19. The limiting rod 19 can limit the movement of the movable plate 12 to achieve the limiting effect of the movable plate 12. A fixed groove 15 is provided on the inner bottom surface of the support frame 4. A bearing 16 is fixedly connected with the inner circular wall surface of the fixed groove 15. The inner circular wall surface of the inner ring of the bearing 16 is movably connected with the outer circular wall surface of the screw rod 17. Through the set screw rod 17, the rotation of the screw rod 17 drives the inner ring of the bearing 16 to rotate. The bearing 16 can support one end of the screw rod 17 to reduce the shaking of the screw rod 17. The bottom surface of the collecting box 2 and the bottom surface of the hull 1 are both provided with circular through holes. The inner circular wall surface of the circular through hole is fixedly sleeved with a sand inlet pipe 6. The inner circular wall surface of the sand inlet pipe 6 is fixedly sleeved with a sand pump 20. The sand pump 20 is electrically connected to the PLC controller. The sand pump 20 is an existing structure and is not described here. Through the set hull 1, the staff puts the hull 1 into the sewage, and the staff starts the sand pump 20. The sand pump 20 sucks the mud and sand in the sewage into the interior of the collecting box 2 through the sand inlet pipe 6, so as to achieve the sand suction effect on the sewage. The inner circular wall surface of the sand inlet pipe 6 is fixedly sleeved with a filter screen 21.

[0029] Working principle: Please refer to Figure 1-Figure 6 As shown, through the arrangement of the hull 1, when the staff puts the hull 1 into the sewage to absorb the silt, the staff will use the rotation of the stirring column 5 to stir the silt on the bottom of the water, and some water plants may be entangled on the stirring column 5 and the installation box 14. The staff squeezes the two placement plates 27 so that the placement plates 27 move inward along the installation column 9 inside the fixed frame 26, and at the same time the spring 32 is compressed. The inward movement of the placement plates 27 also causes the limiting column 29 to move inward to the outside of the limiting groove 30 on the installation block 28. Without the restriction of the limiting column 29, the staff moves the pull rod 3 downward, and the pull rod 3 moves downward inside the connecting hole 7 on the installation box 14. The support block 23 is driven to move downward, and the downward movement of the support block 23 drives the limiting block 25 to move downward inside the limiting hole 24, and at the same time makes the mounting block 28 move downward inside the placement hole 31. The limiting block 25 can limit the movement of the support block 23. The downward movement of the support block 23 also makes the cutting knife 22 move downward. The downward movement of the cutting knife 22 will cut off the aquatic plants entangled on the mounting box 14 and the stirring column 5, thereby achieving the effect of cutting off the aquatic plants on the stirring column 5, which helps the staff to use the stirring column 5 to stir the mud and sand on the bottom of the water, thereby improving the subsequent sand absorption effect on the sewage, and facilitating the staff to absorb the mud and sand in the sewage later.

[0030] Through the provided hull 1, the staff puts the hull 1 into the sewage, and starts the sand suction pump 20, which sucks the silt in the sewage into the interior of the collecting box 2 through the sand inlet pipe 6, so as to achieve the sand suction effect on the sewage. Through the provided first driving motor 8, the driving shaft of the first driving motor 8 rotates to drive the screw rod 17 to rotate, and the screw rod 17 rotates to make the movable plate 12 move downward along the screw rod 17, and the movable plate 12 moves downward to drive the stirring column 5 to move downward into the sewage, so as to adjust the position of the stirring column 5 according to the depth of the sewage.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
