[0033] Reference Figure 2 , Figure 3 and Figure 4, the bottom end of the pump body 1 is provided with a mounting assembly for facilitating the removal of the filter screen 2 for maintenance, the mounting assembly comprises a fixed ring 31 for providing support, the fixed ring 31 is fixedly connected to the bottom end of the pump body 1, the bottom end of the fixed ring 31 is fixedly connected with a mounting block two 32 for mounting the mounting ring 3 with the fixed ring 31, the mounting block two 32 penetrates and movably inserts into the top of the mounting ring 3, the bottom of the mounting ring 3 is fixedly connected with a mounting block three 34 for supporting the butterfly screw 33, the left side of the mounting block three 34 is threadedly connected with the butterfly screw 33 which is threadedly connected with the mounting block two 32 and can connect and fix the mounting ring 3 with the fixed ring 31.

[0034] Further, the butterfly screw 33 is threadedly connected with the mounting block two 32, the inner side of the fixed ring 31 is fixedly mounted with a speed reducer 5, the main function of the speed reducer 5 is to adjust the rotating speed of the motor, reduce the high rotating speed of the motor to a suitable value and transmit it to the connecting rod 27, so as to drive the cleaning mechanism to operate at a proper speed, which can ensure that the cleaning mechanism has enough power to effectively clean the filter screen 2, and can avoid excessive wear or damage of the parts due to high rotating speed, while ensuring the overall operation stability and reliability of the sewage pump, and the speed reducer 5 is prior art and can be realized by those skilled in the art, since it is prior art, it will not be described in detail in this case, the top end of the speed reducer 5 is fixedly connected to the bottom end of the transmission rod 41, the bottom end of the speed reducer 5 is fixedly connected with a rotating rod 23 for driving the connecting rod 27 to rotate, the bottom end of the rotating rod 23 is provided with a cross opening, the top end of the connecting rod 27 is fixedly connected with a cross block, the cross block movably inserts into the inner wall of the cross opening, when the mounting ring 3 and the filter screen 2 are installed, the cross block can be aligned and inserted into the cross opening, so that after installation, the connecting rod 27 can be driven to rotate by the rotating rod 23.

[0035] Working principle: in use, first of all, the electric device in the device is connected to the power supply and switch, when the sewage pump starts, the output shaft of the motor drives the transmission rod 41 to rotate, the transmission rod 41 transmits power to the impeller in the pump body 1, makes the impeller rotate to produce centrifugal force, so that the sewage filtered by the filter screen 2 is sucked from the pump inlet and delivered to the designated position through the water outlet pipe 4, on the other hand, the transmission rod 41 transmits power to the reducer 5 inside the fixed ring 31, the reducer 5 adjusts the high speed of the motor, reduces it to a reasonable value, and then transmits it to the connecting rod 27 through the bottom end of the rotating rod 23, because the cross block at the top of the connecting rod 27 is movably inserted into the cross opening of the rotating rod 23, so the rotating rod 23 can effectively drive the connecting rod 27 to rotate, when the connecting rod 27 rotates, the guide block 26 fixedly connected to the bottom outside of the connecting rod 27 also rotates synchronously, the rotation of the guide block 26 drives the support rod 28 movably inserted into the front end circular groove 25 of the guide block 26 to rotate, and then the brush on the outer wall of the support rod 28 cleans the holes and inner wall of the filter screen 2, the brush can enter the hole of the filter screen 2 and remove the hair, fiber and small sand etc. Impurities stuck in it, to ensure the water passing capacity of the filter screen 2.

[0036] At the same time, the rotation of the connecting rod 27 also drives the circular block 22 fixedly connected to the bottom end of the connecting rod 27 to rotate, the arc-shaped inclined scraper 21 fixedly connected to the outer side of the filter screen 2 near the top of the circular block 22 rotates closely with the outer wall of the filter screen 2 under the drive of the circular block 22, the scraper 21 uses its arc design and inclination angle to scrape off various impurities such as sand particles, large block garbage and fiber winding objects attached to the outer wall of the filter screen 2, and moves the impurities outward, effectively preventing the impurities from reattaching near the filter screen 2 or clogging the filter screen 2 again, and maintaining the good filtering performance of the filter screen 2.

[0037] When the filter screen 2 needs to be maintained, the butterfly screw 33 on the bottom mounting block three 34 of the mounting ring 3 is twisted, since the butterfly screw 33 is screw connected with the mounting block two 32 penetrating through the top of the mounting ring 3, the connection between the mounting ring 3 and the fixed ring 31 can be easily released, so that the filter screen 2 can be conveniently removed for cleaning or replacement, when the brush is seriously worn and affects the cleaning effect, only need to unscrew the screw on the bottom mounting block one 24 of the back surface of the support rod 28, the worn brush can be removed and a new brush can be installed, to ensure that the cleaning mechanism always maintains good working condition, and then ensures the efficient and stable operation of the sewage pump.

[0038] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, the made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
