[0025] This embodiment is a sewage pump for wastewater treatment.

[0026] like Figure 1-5 As shown, the device includes a submersible sewage pump 1, a base 3 at the lower end of the submersible sewage pump 1, a support frame 4 fixedly installed between the lower outer surface of the submersible sewage pump 1 and the upper outer surface of the base 3, a connecting assembly 6 fixedly installed on the upper outer surface of the base 3, a protective assembly 5 snapped into the connecting assembly 6, the protective assembly 5 including a cantilever rod 7, a slot 8, a snap-fit ​​groove 9, a fixing block 10, a connecting shaft 11 and a roller 12, the connecting assembly 6 including an insert block 13, a mounting cavity 14, a compression spring 15, a limiting block 16, a sliding hole 17 and a snap-fit ​​rod 18, the lower outer surface of the insert block 13 is fixedly connected to the upper outer surface of the base 3, and a lifting ring 2 is fixedly installed on the upper outer surface of the submersible sewage pump 1.

[0027] The mounting cavity 14 is located inside the insert block 13, and the sliding hole 17 is located in the middle of one side of the outer surface of the insert block 13, communicating with the mounting cavity 14. The compression spring 15 and the limiting block 16 are both located in the sliding hole 17, and the locking rod 18 passes through the sliding hole 17. The compression spring 15 is fixedly installed between the end of the mounting cavity 14 away from the sliding hole 17 and one side of the outer surface of the limiting block 16, and the locking rod 18 is fixedly installed in the middle of the other side of the outer surface of the limiting block 16. One side of the outer surface of the limiting block 16 is elastically connected to one end of the mounting cavity 14 via the compression spring 15, and the outer wall of the locking rod 18 is slidably connected to the sliding hole 17. The fixed block 10 is fixedly installed on the outer surface of one end of the cantilever 7. The slot 8 is opened on the lower outer surface of the cantilever 7 away from the fixed block 10. The snap-fit ​​groove 9 is opened on the outer surface of one side of the cantilever 7 away from the fixed block 10. The snap-fit ​​groove 9 communicates with the slot 8. The connecting shaft 11 is fixedly installed in the middle of the outer surface of one side of the roller 12 and is connected to the fixed block 10. The outer wall of the insert block 13 is inserted into the slot 8. The outer wall of one end of the snap-fit ​​rod 18 is snapped into the snap-fit ​​groove 9.

[0028] It should be noted that this utility model is a sewage pump for sewage treatment. The sewage submersible pump 1 described in this article belongs to the prior art and can be effectively known to those skilled in the art. Specific details will not be elaborated further. The protective component 5 is provided, and during assembly between the protective component 5 and the base 3, the locking rod 18 in the connecting component 6 is pressed, causing one end of the locking rod 18 to enter the sliding hole 17. The locking rod 18 drives the limiting block 16 to press the compression spring 15 in the mounting cavity 14. Then, the cantilever rod 7 is fitted onto the insert block 1. The outer wall of the 3 is inserted into the slot 8. When the locking rod 18 reaches one end of the locking groove 9, the reaction force released by the compression spring 15 drives one end of the locking rod 18 to be inserted into the locking groove 9, thereby realizing the installation of the protective component 5, which is convenient for assembly and disassembly. When the sewage submersible pump 1 is lowered into the sewage well by the rope, the roller 12 of the protective component 5 contacts the well wall, which prevents the sewage submersible pump 1 from contacting the well wall, reduces the resistance when the sewage submersible pump 1 descends, and allows the sewage submersible pump 1 to reach the bottom of the well more smoothly, which is convenient for use.
