[0015] The working principle and beneficial effects of the utility model are:

[0016] In the utility model, when water flows through the installation cylinder, the check block 1 and the check block 2 are opened by the impact force of the water flow, and are discharged after passing through the check groove. In the process, the check block 1 and the check block 2 are driven to rotate with the center of the positioning rod as the center point, and the two ends of the machine spring are squeezed and offset. After the water flow is discharged, the machine spring is reset, driving the check block 1 and the check block 2 to fit again on the inner wall of the installation cylinder, and the excess water source remains in the check groove, thereby achieving the anti-backflow effect inside the shell, and can prevent the impact and pressure wave caused by the backflow, thereby effectively preventing the sewage from flowing back into the shell or the pipeline system when the pump stops running, avoiding the environmental pollution and health risks that may be caused by the backflow of sewage.

[0017] In the utility model, the bevel gear one is driven by a motor to operate, and the bevel gear one itself is driven to rotate the bevel gear two and the bevel gear three, and the rotation directions of the bevel gear two and the bevel gear three are opposite.

The connecting blocks 19 and 20 are both rotatably connected to the positioning rod 2 1, a machine spring 22 is fixedly installed in the middle of the outer side of the positioning rod 21, in order to further improve the stability of the machine spring 22, and the two ends of the machine spring 22 are respectively located in the middle of the right side of the check block 17 and the check block 2 18, and a check groove 23 is provided at the right end of the inner wall of the installation cylinder 16, and a limit rod 24 is fixedly connected to the middle end of the inside of the check groove 23, in order to further improve the stability of the limit rod 24, and the check block 1 17 and the check block 2 18 are both fitted with the inner wall of the installation cylinder 16. By fitting the check block 1 17 and the check block 2 18 with the inner wall of the installation cylinder 16, the backflow prevention effect inside the shell 1 can be achieved, and the impact and pressure wave caused by the backflow can be prevented, thereby effectively preventing the sewage from flowing back into the shell 1 or the pipeline system when the pump stops running. Example 2

[0028] On the basis of Example 1, a preferred embodiment of the submersible sewage pump with anti-blocking function provided by the utility model is as follows Figures 1 to 6 As shown: a mounting cover 2 is fixedly connected to the left side of the shell 1, and the shell 1 fixes the mounting cover 2; a mounting frame 3 is fixedly connected to the left side of the mounting cover 2, and the mounting cover 2 fixes the mounting frame 3.

[0029] In this embodiment, a motor 4 is fixedly connected to the top of the mounting frame 3 in order to further improve the stability of the motor 4. A bevel gear 5 is fixedly connected to the driving end of the motor 4, and the motor 4 can drive the bevel gear 5 to rotate. The left side of the bevel gear 5 is meshedly connected with a bevel gear 2 6, which further drives the bevel gear 2 6 to rotate.

[0030] In this embodiment, a transmission rod 7 is fixedly connected to the inner wall of the bevel gear 2 6, and the transmission rod 7 is driven to rotate by the rotation of the bevel gear 2 6. The left end of the transmission rod 7 is rotatably connected to the inner wall of the mounting frame 3, and the outer side of the transmission rod 7 is fixedly connected to evenly distributed cutting knives 8, which further drives the cutting knives 8 to rotate.

[0031] In this embodiment, bevel gear one 5 is meshedly connected with bevel gear three 9 on the right side. Bevel gear one 5 drives bevel gear three 9 to rotate synchronously during rotation, and the rotation direction of bevel gear three 9 is opposite to that of bevel gear two 6. A sleeve rod 10 is fixedly connected to the inner wall of bevel gear three 9. The sleeve rod 10 is rotatably connected to the outer side of the transmission rod 7. The rotation of bevel gear three 9 drives the sleeve rod 10 to rotate without affecting the operation of the transmission rod 7.

[0032] In this embodiment, a connecting rod 11 opposite to each other is fixedly connected to the outside of the sleeve rod 10, and the sleeve rod 10 rotates to drive the connecting rod 11 to rotate. A connecting plate 12 is fixedly connected to one side of the connecting rod 11, which further drives the connecting plate 12 to rotate. A fixing rod 13 is fixedly connected between the two connecting plates 12 to further improve the stability of the fixing rod 13 during rotation.

[0033] In this embodiment, the inner wall of the connecting plate 12 is fixedly connected with evenly distributed springs 14, and the other end of the spring 14 is fixedly connected with a brush 15. The connecting plate 12 rotates to drive the brush 15 to rotate, and the brush 15 is affected by inertia during the rotation and moves on the inner wall of the connecting plate 12, driving the spring 14 to contract, thereby preventing the brush 15 from being in contact with the inner wall of the shell 1 for a long time, causing damage to the brush 15, and further improving the service life of the brush 15.

[0034] Furthermore, a connecting pipe 25 is fixedly installed on the left side of the front end of the shell 1.

[0035] The working principle and use process of the utility model are as follows: first, sewage enters the shell 1 through the connecting pipe 25, and the motor 4 is started, and the bevel gear 1 5 is driven to rotate by the motor 4. During the rotation process, the bevel gear 1 5 drives the bevel gear 2 6 and the bevel gear 3 9 to rotate synchronously through its own meshing transmission, and the rotation directions of the bevel gear 2 6 and the bevel gear 3 9 are opposite. The rotation of the bevel gear 2 6 drives the transmission rod 7 and the cutting knife 8 to rotate synchronously, and the cutting knife 8 can cut the debris inside the shell 1, and the bevel gear 3 9 drives the sleeve rod 10 to rotate during the rotation process, and further drives the connecting rod 11, the connecting plate 12 and the fixed rod 13 to rotate, and the fixed rod 13 rotates to make the brush 15 rotate, and the brush 15 is affected by inertia during the rotation process and moves on the inner wall of the connecting plate 12, and drives the spring 14 to contract. This prevents the brush 15 from being in contact with the inner wall of the shell 1 for a long time, causing damage to the brush 15, and further improves the service life of the brush 15. When the sewage flows through the installation cylinder 16, the check block 17 and the check block 2 18 are opened by the impact of the water flow, and are discharged after flowing through the check groove 23. In the process, the check block 17 and the check block 2 18 are driven to rotate with the center of the positioning rod 21 as the center point, and the two ends of the machine spring 22 are squeezed and offset. After the water flow is discharged, the machine spring 22 is reset, driving the check block 17 and the check block 2 18 to fit again on the inner wall of the installation cylinder 16, and the excess water source remains in the check groove 23, thereby achieving the anti-backflow effect inside the shell 1, and can prevent the impact and pressure wave caused by the backflow, thereby effectively preventing the sewage from flowing back into the shell 1 or the pipeline system when the pump stops running, avoiding the environmental pollution and health risks that may be caused by the backflow of sewage.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
