[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] (1) Start the driving motor so that its output end can drive the rotating disc to rotate through the rotating slot, so that the rotating ring on it rotates in a number of rotating blocks, and the submersible propeller is placed on the arc base, and the arc base is placed on the rotating disc through the U-shaped square seat. When the rotating disc rotates, it can drive the submersible propeller to rotate, so that its output end can rotate 360 ​​degrees, so that the submersible propeller can work in different directions, and the rotation process is carried out during the working process of the submersible propeller, so as to avoid the submersible propeller being unable to adjust its working direction when in use, and avoid the submersible propeller being fixed in a single direction, thereby reducing the limitations of the anaerobic tank in treating sewage, improving the effect and efficiency of the anaerobic tank in treating sewage, and thus improving the use effect of the anaerobic tank;

[0016] (2) Loosen the latch block so that the reset of the auxiliary spring drives the locking block on the latch block to reset and move, so that it is connected to one of the blocking slots, thereby limiting the blocking square column to the current position, so that the submersible propulsion unit can be limited to the current height for use, avoiding the phenomenon of dislocation of the submersible propulsion unit during use, which causes its use height to change. At the same time, it also avoids the submersible propulsion unit's use position to change due to non-human factors during use, further reducing the limitations of the submersible propulsion unit during use, so that the submersible propulsion unit can be stably used at the current height, and improving the anaerobic tank's sewage treatment effect and efficiency; it is worth mentioning that the height position of the submersible propulsion unit can be adjusted manually and automatically. When automatic adjustment is required, it is only necessary to replace the latch block with a device similar to a telescopic electric rod. At the same time, when the submersible propulsion unit is limited to the current height, the power supply to the telescopic electric rod can be canceled, avoiding the telescopic electric rod being in use all the time, which causes excessive energy consumption, reducing the energy cost of the anaerobic tank during use, and reducing the limitations of the anaerobic tank in sewage treatment;

[0017] (3) The two locking arc blocks move relative to each other, that is, they both move toward the side wall of the submersible propulsion device, and until the locking arc blocks contact the submersible propulsion device, thereby fixing the submersible propulsion device and limiting the submersible propulsion device at the current position, thereby fixing the submersible propulsion device on the installation square plate, making it integrated, and convenient for integrated installation in the pool for use. At the same time, the submersible propulsion device is prevented from shaking or dislocating due to factors such as water flow during use, thereby improving the stability of the submersible propulsion device during use, avoiding the instability of the submersible propulsion device during use and causing its poor use effect, thereby improving the use effect of the submersible propulsion device; at the same time, the buffering performance brought by the provided buffer rubber pad can reduce the impact force generated by the submersible propulsion device during use, and at the same time increase the friction between the locking arc block and the submersible propulsion device, thereby improving the installation effect of the submersible propulsion device;

[0018] (4) A submersible propeller is used in the pool body so that the stirring blades at the output end continuously stir the water, generating a strong water flow with low tangential flow, thereby improving the water flow state, enhancing the water mixing effect, and improving the dissolved oxygen efficiency, so that the efficiency of sewage treatment can be increased, sludge precipitation in the pool is avoided, and the sewage and the injected medicines are evenly distributed. At the same time, the propulsion efficiency of the submersible propeller can be improved by the provided guide cover, and the flow direction of the propeller output water flow can be changed to make it more concentrated and directional, reducing the diffusion of the water flow and energy loss. At the same time, it can also prevent large foreign objects in the water (such as branches, garbage, etc.) from directly contacting and damaging the propeller. The stirring blade improves the sewage treatment effect and efficiency of the anaerobic tank; at the same time, when the submersible propeller on the mounting square plate is installed in the tank, the rubber airbag at the bottom of the mounting square plate is in contact with the inner bottom surface of the tank body. The cushioning performance brought by the rubber airbag can continuously adjust the installation position of the mounting square plate, and can wrap the uneven area on the bottom surface of the tank body to prevent the uneven area from affecting the installation state of the mounting square plate, so as to ensure that the mounting square plate can be in a horizontal state during installation, and avoid the submersible propeller from being tilted during use and affecting its normal use, so that the limitations of the anaerobic tank during use are reduced;

[0019] (5) When the rotating disc adjusts the working direction of the submersible propulsion device, the rotating gear rotates, and the driving disc is driven to rotate under the action of the rotating shaft, the rotating bevel gear, the driving bevel gear and the driving shaft, so that the driving column is driven to rotate, so that the driving column moves back and forth in the torque slide, so that the driving torque plate moves back and forth on the limiting base through the limiting cylinder, so that the reciprocating movement of the driving torque plate drives the scraper block to move back and forth, so that the scraper moves back and forth on the output side of the deflector, which can clean the impurities adhered to the deflector when in use, and the cleaning process is carried out when the submersible propulsion device adjusts its working direction, avoiding the cleaning operation during its work, which causes the use effect of the submersible propulsion device to be reduced, and avoiding the deflector from adhering too many impurities when in use, affecting the output efficiency of the submersible propulsion device, improving the effect of the submersible propulsion device when in use, and further improving the effect and efficiency of the anaerobic tank in treating sewage, thereby reducing the limitations of the anaerobic tank when in use;

[0020] (6) Start the telescopic electric rod so that its output end drives the T-shaped base plate to move on the upper limit of the guide slide column, so that the guide spring is in a buffering state, and then the U-shaped square seat on the T-shaped base plate can move up and down, thereby adjusting the use height of the submersible propulsion device, so that it can be used at different heights in the pool, so that the sewage can be better mixed in the vertical direction, avoiding the poor fluidity of local sewage affecting the sewage treatment effect, reducing the dead angle of the submersible propulsion device when in use, and further improving the effect of the submersible propulsion device when in use, thereby improving the efficiency and effect of the anaerobic tank in treating sewage; thereby reducing the limitations of the anaerobic tank when in use;

[0021] (7) When the locking arc block has come into contact with the submersible thruster, the locking arc block is unable to move, so that the locking square column on it is positioned at the current position. Through the continued movement of the locking horizontal plate, the locking square cylinder on the locking horizontal plate is also limited in the locking square column. The locking spring is in a buffering state, thereby strengthening the contact strength between the locking arc block and the submersible thruster, avoiding the submersible thruster from being dislocated due to non-human factors when used in the pool, further improving the installation effect and strength of the submersible thruster, and reducing the limitations of the anaerobic tank in treating sewage.

[0042] When the submersible propulsion device 2 is in use, the telescopic electric rod 31 is activated, so that its output end drives the T-shaped base plate 27 to move on the upper limit of the guide slide column 28, so that the guide spring 29 is in a buffering state, and then the U-shaped square seat 7 on the T-shaped base plate 27 can be moved up and down, thereby adjusting the use height of the submersible propulsion device 2, so that it can be used at different heights in the pool, so that the sewage can be better mixed in the vertical direction, avoiding the poor fluidity of local sewage affecting the sewage treatment effect, reducing the dead angle of the submersible propulsion device 2 when in use, further improving the effect of the submersible propulsion device 2 when in use, thereby improving the efficiency and effect of the anaerobic tank in treating sewage; thereby reducing the limitations of the anaerobic tank when in use;

[0043] When the position of the U-shaped square seat 7 changes, the blocking square column 32 on it moves within the blocking square cylinder 33, so that the blocking spring 34 is in a buffering state, avoiding the position change of the U-shaped square seat 7 during movement, thereby improving the stability of the submersible propulsion device 2 during movement; it is worth mentioning that when the height position of the submersible propulsion device 2 needs to be adjusted, by pulling the latch cross block 50 outward, the auxiliary cylinder 49 on it moves within the limit position on the auxiliary base 48, so that the auxiliary spring 52 is in a buffering state, and then the locking plug 51 on the latch cross block 50 is no longer in contact with the blocking slot 35, thereby releasing the limit setting of the blocking square column 32, so that the submersible propulsion device 2 can adjust the height position; when the height adjustment of the submersible propulsion device 2 is completed, by loosening the latch cross block 50, the locking plug 51 on the latch cross block 50 is driven by the reset of the auxiliary spring 52 to reset and move it, so that it is connected with one of the blocking slots 35, thereby limiting the blocking square column 32 Being located at the current position, the submersible propulsion device 2 can be limited to the current height for use, avoiding the phenomenon of dislocation of the submersible propulsion device 2 during use, which causes its use height to change. At the same time, it also avoids the submersible propulsion device 2 from changing its use position due to non-human factors during use, further reducing the limitations of the submersible propulsion device 2 during use, allowing the submersible propulsion device 2 to be stably used at the current height, and improving the treatment effect and efficiency of the anaerobic tank for sewage; it is worth mentioning that the height position of the submersible propulsion device 2 can be adjusted manually and automatically. When automatic adjustment is required, it is only necessary to replace the locking cross block 50 with a device similar to the telescopic electric rod 31. At the same time, when the submersible propulsion device 2 is limited to the current height, the power supply to the telescopic electric rod 31 can be canceled, avoiding the telescopic electric rod 31 being in use all the time, resulting in excessive energy consumption, reducing the energy cost of the anaerobic tank during use, and reducing the limitations of the anaerobic tank in treating sewage.
