When the rotating shaft 2 rotates, the convex block can be used to drive the moving tube 3 to slide and also to rotate, the outer wall of the rotating shaft 2 is slidably connected with the moving tube 3, and the right end of the moving tube 3 is an inclined surface, so that the inclined surface can contact with the contact tube 6 to make the moving tube 3 move, and a stirring mechanism is arranged on the left end of the moving tube 3, a circular ring 5 is fixedly connected with the left end of the motor box 1, and a contact tube 6 is fixedly connected with the left end of the motor box 1, and a sleeve 7 is slidably connected with the inner wall of the circular ring 5, and the right end of the sleeve 7 is a circular tube, which slides along the inner wall of the circular ring 5 through the circular tube, and will not block the normal rotation of the moving tube 3, and the inner wall of the right end of the sleeve 7 is elastically connected with a sliding rod 9 through a reset spring 8.

[0026] See also Figure 4-Figure 6 The right end of the motor box 1 is fixedly connected with a fixed block 10, and there are plug-in plates on both sides of the fixed block 10 at the right end of the motor box 1. The fixed block 10 and the plug-in plate are made of steel material with sufficient hardness. A slider 11 is inserted into the outer wall of the fixed block 10, and there is an L-plate on the slider 11, which can allow the plug-in plate to be plugged into the L-plate to ensure the stability of the overall motor box 1 after installation. The inner wall of the right end of the slider 11 is elastically connected to the limit block 13 through a positioning spring 12. The limit block 13 is an inclined surface. When the limit block 13 is squeezed, the limit block 13 will slide along the inner wall of the slider 11, and the inner wall of the slider 11 is provided with a lifting mechanism.

[0027] The inner wall of the right end of the slider 11 is fixedly connected to one end of the positioning spring 12. When the limit block 13 moves to the right, the positioning spring 12 will be compressed. When resetting, the elastic force of the positioning spring 12 is used to reset the limit block 13. The other end of the positioning spring 12 is fixedly connected to the right end of the limit block 13. The limit block 13 passes through and is slidably connected to the inner wall of the slider 11. The limit block 13 is plugged into the inner wall of the fixed block 10. The fixed block 10 is provided with a notch corresponding to the limit block 13, so that the limit block 13 can be plugged into it. The lifting mechanism includes a threaded rod 14. The outer wall of the threaded rod 14 is threadedly connected to the inner wall of the slider 11. The slider 11 is moved vertically with the motor box 1 as a whole by forward and reverse rotation of the threaded rod 14. The outer wall of the threaded rod 14 passes through and is rotatably connected with a support column 15. The support column 15 is fixed to the edge of the sewage treatment tank by existing bolts.

[0028] See also Figure 1-Figure 3 The inner wall of the right end of the sleeve 7 is fixedly connected to one end of the return spring 8. When the slide bar 9 moves to the left, the return spring 8 will be stretched. When resetting, the return spring 8 is used to return the slide bar 9. The other end of the return spring 8 is fixedly connected to the right end of the slide bar 9. The slide bar 9 passes through and is slidably connected to the inner wall of the sleeve 7. The left end of the contact tube 6 contacts the right end of the moving tube 3. The stirring mechanism includes a stirring blade 4, which is arranged on the outer wall of the moving tube 3. The stirring blade 4 is an existing submersible stirring technology and will not be described in detail here. The left end of the slide bar 9 is fixedly connected to the outer wall of the moving tube 3.

[0029] Working principle: When the stirring position of the motor box 1 needs to be adjusted, it is only necessary to rotate the threaded rod 14 to allow the slider 11 to move upward with the fixed block 10, the slider 11 and the motor box 1, so that the entire motor box 1 reaches the specified stirring position. When it is necessary to adjust again, it is only necessary to rotate the threaded rod 14 in the opposite direction to allow the slider 11 to move downward with the fixed block 10 and the slider 11.

[0030] When stirring is needed, it is only necessary to start the driving motor in the motor box 1, and let the output shaft of the driving motor rotate with the rotating shaft 2 and the moving tube 3, the stirring blade 4, the sliding rod 9 and the sleeve 7, so that the right end inclined surface of the moving tube 3 is squeezed by the contact tube 6, and the moving tube 3 moves to the left with the sliding rod 9 and the stirring blade 4 to expand the stirring range. At this time, the reset spring 8 is in a stretched state. When the highest inclined surface of the moving tube 3 contacts the contact tube 6, the moving tube 3 and the stirring blade 4 move to the maximum range. When the lowest inclined surface of the moving tube 3 contacts the contact tube 6, as shown in FIG. Figure 2 In the state shown, the reverse elastic force of the return spring 8 is utilized to completely return the slide bar 9 and the moving pipe 3 to a better stirring effect on the sewage treatment tank.

[0031] When the motor box 1 needs to be disassembled, it is only necessary to move the limit block 13 to the right and compress the positioning spring 12 to separate the limit block 13 from the notch of the fixed block 10, and then move the motor box 1 to separate the fixed block 10 and the slider 11, and finally release the limit block 13 and use the reverse elastic force of the positioning spring 12 to reset the limit block 13. When the motor box 1 needs to be installed, it is only necessary to plug the fixed block 10 and the plug plate with the slider 11 and the L plate, and use the right end of the fixed block 10 to squeeze the inclined surface of the limit block 13 to move the limit block 13 to the right and compress the positioning spring 12. When the limit block 13 coincides with the notch of the fixed block 10, use the reverse elastic force of the positioning spring 12 to reset the limit block 13, and plug the limit block 13 with the notch of the fixed block 10 to limit the entire motor box 1 in one direction, thereby completing the disassembly and assembly process of the entire motor box 1.
