Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5 , the present utility model provides a technical solution: a submersible pump protection device, including a base 1, the upper surface of the base 1 is welded and fixed to the fixed plate 2. The base 1 is rectangular, and the fixed plate 2 is a circular plate. Four symmetrically arranged chutes 3 are opened on the upper surface of the fixed plate 2. The inside of the chute 3 is slidably connected to the sliding rod 4. The top of the sliding rod 4 is welded and fixed to the clamping plate 5. The clamping plate 5 is an arc-shaped plate, and the side of the clamping plate 5 is adhesively fixed to the protective pad. The bottom end of the base 1 is rotatably connected to the rotating shaft 6. The outside of the rotating shaft 6 is rotatably connected to the center of the fixed plate 2 through a bearing. The top of the rotating shaft 6 is welded and fixed to the rotating plate 7. Four symmetrically arranged limiting grooves 8 are opened on the rotating plate 7. The outside of the rotating shaft 6 is welded and fixed to the worm gear 9. One end of the worm 10 is rotatably connected to the inner wall of the base 1. The first annular groove 11 is opened on the upper surface of the fixed plate 2. One end of the L-shaped bracket 12 is slidably connected to the inside of the first annular groove 11. A connecting block 13 is provided at one end of the L-shaped bracket 12. The connecting block 13 is located at the center of the fixed plate 2. The second annular groove 14 is opened on the side of the connecting block 13. The side of the L-shaped bracket 12 is welded and fixed to the fixed block 15. The insertion hole 16 is opened on the upper surface of the fixed block 15. The guide groove 17 is opened on the inner wall of the insertion hole 16. The fixed groove 18 is provided inside the insertion hole 16. The arc-shaped bracket 19 is provided on the fixed block 15. One side of the L-shaped bracket 12 is welded and fixed to the hinge plate 20. The insertion rod 21 is provided on the arc-shaped bracket 19. The outside of the insertion rod 21 is welded and fixed to the guide bar 22. The top of the insertion rod 21 is welded and fixed to the rotating plate 23.

[0022] To ensure the horizontal linear movement of the clamping plate 5, the chute 3 is a straight groove. The number of chutes 3 is four and they are symmetrically distributed. The inside of the chute 3 is slidably connected to the slide bar 4. The top of the slide bar 4 passes through the limit groove 8 and extends above the rotating plate 7 and is welded and fixed to the clamping plate 5. The limit groove 8 is an arc-shaped groove, and the number of the limit grooves 8 is the same as that of the chutes 3. One end of the worm 10 extends outside the base 1 and is welded to the handwheel. The outside of the worm 10 is meshed with the worm gear 9. Rotating the handwheel causes the worm 10 to drive the rotating shaft 6 and the worm gear 9 to rotate synchronously, so that the rotating plate 7 rotates. Further, the slide bar 4 is pushed to move inside the chute 3 through the limit groove 8 until the clamping plate 5 is clamped and fixed to the outside of the submersible pump, effectively reducing the workload of the staff and improving the efficiency of the staff. At the same time, the four arc-shaped clamping plates 5 in different directions can clamp and fix the submersible pump more stably;

[0023] To enhance the protection effect on the submersible pump, the protection of the submersible pump is realized by the staggered connection of the L-shaped brackets 12 and the arc-shaped brackets 19 to form a protection net. The L-shaped brackets 12 are distributed in a circular array around the center of the connection block 13. The two ends of the L-shaped brackets 12 are dovetail-shaped, and the two ends of the L-shaped brackets 12 are respectively slidably connected to the inner walls of the annular groove one 11 and the annular groove two 14. The jacks 16 are respectively communicated with the guide grooves 17 and the fixed grooves 18. The inside of the jacks 16 is movably inserted with the outside of the plug rods 21. The guide bars 22 are slidably connected to the inside of the guide grooves 17. The fixed grooves 18 are annular grooves, and the inside of the fixed grooves 18 is slidably connected to the guide bars 22. The submersible pump can be conveniently installed and disassembled from the inside by moving the L-shaped brackets 12, enhancing the actual use effect.

[0024] Working principle: When in use, the staff pushes the L-shaped bracket 12 so that the two ends of the L-shaped bracket 12 slide inside the annular groove one 11 and the annular groove two 14 respectively. After all the L-shaped brackets 12 are fitted together, the submersible pump is placed on the upper surface of the rotating plate 7. Rotating the handwheel causes the worm 10 to drive the rotating shaft 6 and the worm gear 9 to rotate synchronously, so that the rotating plate 7 rotates. Further, the slide bar 4 is pushed to move inside the chute 3 through the limit groove 8 until the clamping plate 5 is clamped and fixed to the outside of the submersible pump, enhancing the stability of the installation of the submersible pump and being convenient to operate. Then, the L-shaped bracket 12 is moved to a suitable position, and then the arc-shaped bracket 19 is rotated to fit the upper surface of the fixed block 15, and the plug rod 21 is inserted into the jack 16. Pressing the plug rod 21 downwards causes the guide bar 22 to slide inside the guide groove 17. Then, the plug rod 21 is rotated through the rotating plate 23, and the guide bar 22 is rotated from the guide groove 17 to the inside of the fixed groove 18. The arc-shaped bracket 19 and the fixed block 15 are connected and fixed through the staggered distribution of the guide bar 22 and the guide groove 17, preventing the arc-shaped bracket 19 from separating from the fixed block 15 during use.
