Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-4 The submersible sewage pump for sewage treatment shown in the figure comprises an L-shaped rectangular tube 1, a connecting tube 3 fixedly connected at the bottom, and a pump body 7 provided on one side. One side of the connecting tube 3 is provided with a transmission box 4 which can break the sundries contained inside by rotation to facilitate sewage discharge. Both sides of the top surface of the connecting tube 3 are provided with limiting sliding rods 5 which are convenient for installing the pump body 7 by sliding. The opposite sides of the rod walls of the two limiting sliding rods 5 are provided with circular sliders 6 which can make the installation and docking precise by sliding. The utility model utilizes the two limiting sliding rods 5 provided on the top of the connecting tube 3, so that when installing the pump body 7, it only needs to use the circular slider 6 to pass through the rod wall of the limiting sliding rod 5 and fix it on the anti-slip sleeve 604 by a pull rope. Finally, the transportation work of the pump body 7 can be completed by sliding between the circular slider 6 and the limiting sliding rod 5, thereby avoiding that most of the pump bodies 7 are damaged by weight when they are transported to the bottom of the sewage tank. The sliding effect between the circular slider 6 and the limiting sliding rod 5 can make the transportation work more stable, improve the stability during docking installation, make the installation simple, and also reduce the damage rate of the pump body 7.

[0022] like Figure 1-3 As shown, the transmission box 4 is fixedly connected to one side of the surface of the connecting pipe 3, and a transmission cavity 401 is opened inside the transmission box 4. A transmission motor 402 is fixedly connected to the bottom surface of the inner wall of the transmission cavity 401, and a rotating rod 403 is fixedly connected to the transmission motor 402. One end of the rotating rod 403 passes through one side of the inner wall of the transmission cavity 401 and extends to the bottom of the L-shaped rectangular tube 1 and the inside of the connecting pipe 3. The rotating rod 403 is located at the bottom of the L-shaped rectangular tube 1 and the rod wall inside the connecting pipe 3. A crushing blade 404 is provided. When the crushing blade 404 is used for sewage discharge treatment, It is able to crush the solid particles and limiting materials contained in the sewage, making the final processing work easier. When the pump body 7 is working, the sewage will be extracted through the bottom of the pump body 7, and the sewage will enter the interior of the connecting pipe 3 through the flange 605. At this time, the transmission motor 402 inside the transmission box 4 starts to work, and the output end drives the rotating rod 403 to rotate, so that the rotating rod 403 located inside the connecting pipe 3 also rotates, so that the solid particles or fiber materials contained in the sewage are crushed and finally discharged from the top of the L-shaped rectangular tube 1.

[0023] like Figure 1 and Figure 4As shown, the two limit sliding rods 5 are both arranged on both sides of the top surface of the connecting pipe 3, and the two sides of the top surface of the connecting pipe 3 are fixedly connected with connecting blocks 501, and the two limit sliding rods 5 are fixedly connected to the top surfaces of the two connecting blocks 501, and one side of the two limit sliding rods 5 is commonly fixedly connected with a stabilizing block 502, and the stabilizing block 502 is fixed on the top of the sewage tank. The limit sliding rod 5 represents the depth of the sewage tank, which can better facilitate the staff to transfer the main body, and the two circular sliders 6 are slidably connected to the opposite side of the rod wall of the two limit sliding rods 5, and the opposite side of the two circular sliders 6 are fixedly connected with a stabilizing rod 601. The setting of the stabilizing rod 601 can make the two circular sliders 6 more stable when sliding on the rod wall of the limit sliding rod 5. The interior of the two circular sliders 6 is provided with a sliding groove 602 matching the rod wall of the two limit sliding rods 5. The setting of the sliding groove 602 facilitates sliding transmission, so that the installation of the pump body 7 To achieve completeness, one side of the surface of the two circular sliders 6 is fixedly connected with an extension block 603, and the surfaces of the two extension blocks 603 are provided with anti-slip sleeves 604. The anti-slip sleeves 604 can increase the friction of the pull rope, and one side of the surface of the two extension blocks 603 is fixedly connected with a flange 605. The two pull ropes are respectively wrapped around the surfaces of the two anti-slip sleeves 604, and the slide grooves 602 opened inside the two circular sliders 6 are respectively connected to the opposite sides of the two limit sliding rods 5. At this time, the staff only needs to use the two wrapped pull ropes for traction and slowly lengthen the pull ropes. At this time, the slide grooves 602 provided inside the two circular sliders 6 will slide with the surfaces of the two limit sliding rods 5, and slowly make the pump body 7 fixedly connected to one side of the flange 605 move downward. When it moves to the bottom, the flange 605 will be connected to one side of the connecting pipe 3, and the bottom of the pump body 7 will be in a suspended state, so that the sewage treatment efficiency is improved.

At this time, the staff only needs to use the two wrapped pull ropes for traction and slowly lengthen the pull ropes. At this time, the slide grooves 602 provided in the two circular sliders 6 will slide with the surfaces of the two limit sliding rods 5, and slowly move the pump body 7 fixedly connected to one side of the flange 605 downward. When it moves to the bottom, the flange 605 will be docked with one side of the connecting tube 3, and the bottom of the pump body 7 will be in a suspended state, so that the sewage treatment efficiency is improved;

[0025] When the pump body 7 is working, the sewage will be extracted through the bottom of the pump body 7, and the sewage will enter the interior of the connecting pipe 3 through the flange 605. At this time, the transmission motor 402 inside the transmission box 4 starts to work, and the output end drives the rotating rod 403 to rotate, so that the rotating rod 403 located inside the connecting pipe 3 also rotates, so that the solid particles or fiber materials contained in the sewage are broken, and finally discharged from the top of the L-shaped rectangular tube 1.
