The shredder box is installed on the fixed base, the fixed base is threaded on the water inlet of the submersible sewage pump, and many parts are installed in the shredder box. Therefore, the design is large in size and heavy in weight. When the shredder box needs to be removed, maintenance personnel often find that the fixed base is difficult to rotate and consumes a lot of effort, which is not conducive to disassembly by maintenance personnel. Therefore, improvements are needed. Utility Model Content

[0023] refer to Figure 2 , the fixing assembly 8 includes a frame 83, the frame 83 is fixedly connected to one end of the first fixing seat 4, a slider 82 is slidably connected inside the frame 83, one end of the slider 82 is fixedly connected to a plug rod 81, one side of the plug rod 81 is movably connected to the plug block 7, a spring 84 is fixedly connected between the slider 82 and the frame 83, both sides of the interior of the frame 83 are provided with guide grooves 9, one side of the slider 82 is slidably connected to the guide groove 9; by setting the fixing assembly 8, the slider 82 is pushed, and the slider 82 drives the plug rod 81 to move. When the plug rod 81 leaves the round hole on the plug block 7, the plug block 7 and the slot 5 can be separated, and the slider 82 can drive the plug rod 81 to move under the action of the spring 84. When the plug rod 81 is inserted into the round hole on the plug block 7, the plug block 7 is connected and fixed to the slot 5, so that the mounting pipe 3 is fixed to the submersible sewage pump body 1. By setting the guide groove 9, one side of the slider 82 is located in the guide groove 9, which not only prevents the slider 82 from falling off, but also makes the spring 84 stably deformed, so that the slider 82 slides more stably in the frame 83.

[0024] refer to Figure 2, one end of the slider 82 away from the insertion rod 81 is fixedly connected with a pull rod 10, one end of the pull rod 10 is fixedly connected with a pull block 11, one side of the pull block 11 is threadedly connected with a screw 12, and a screw groove 13 is opened on one side of the frame 83, one end of the screw 12 is fixedly connected with a torsion block 14, and one side of the screw 12 is threadedly connected to the screw groove 13; by fixing the pull rod 10 on the slider 82, the pull rod 10 is connected to the pull block 11, and the slider 82 can be driven to move in the frame 83 through the pull block 11, which is convenient for maintenance personnel to operate, and the torsion block 14 is rotated to drive the screw 12 to rotate on the pull block 11, so that the screw 12 is screwed into the screw groove 13 of the frame 83, so that the pull rod 10 remains fixed, thereby keeping the slider 82 fixed, preventing the insertion rod 81 from moving, and making the connection between the mounting pipe 3 and the submersible sewage pump body 1 more firmly and reliably.

[0025] refer to Figure 1 A docking ring 20 is fixedly connected to one end of the submersible sewage pump body 1, and a docking groove 21 is opened at one end of the mounting pipe 3, and the docking ring 20 is movably connected to the docking groove 21; by fixing the docking ring 20 at the water inlet of the submersible sewage pump body 1, a docking groove 21 is opened on the mounting pipe 3, and the docking ring 20 is inserted into the docking groove 21, and a sealing strip is provided in the docking groove 21, so that the mounting pipe 3 and the water inlet of the submersible sewage pump body 1 are more tightly connected.

[0026] refer to Figure 5 One end of the frame 22 is fixedly connected to a fixing block 26, and the fixing block 26 is fixedly connected to the mounting tube 3 by a screw 27; by setting a disassembly screw 27, the fixing block 26 is no longer fixed to the mounting tube 3, and the frame 22 and other components can be removed from the mounting tube 3 for maintenance.

[0027] Principle and advantages of use: When in use, sewage enters from the pipe opening of the installation pipe 3, and the garbage in the sewage is blocked by the filter screen 25 and chopped by the shredder blade 24, which prevents the submersible sewage pump from being blocked and prolongs the service life of the submersible sewage pump. When the installation pipe 3 needs to be disassembled and removed for maintenance of the internal structure, the torsion block 14 is rotated to make the screw rod 12 leave the screw groove 13, and then the pull block 11 can be pulled, and the pull block 11 drives the pull rod 10 to move, so that the pull rod 10 drives the slider 82 to move in the frame 83, and the slider 82 drives the plug rod 81 to move away from the plug block 7 , then hold the anti-slip sleeve 19 to make the handle 18 drive the mounting tube 3 to move, the support block 15 under the mounting tube 3 moves on the support plate 2, and at the same time, the multiple pulleys 16 under the support block 15 move in the slide groove 17 of the support plate 2, so that the mounting tube 3 can be quickly removed, and it is also easy to transfer to other locations for maintenance. Therefore, it only needs to move the mounting tube 3 horizontally to remove it. Compared with the traditional threaded connection or flange connection, the plug-in design does not require the use of tools for tightening or loosening, which greatly saves maintenance time and labor costs.
