Abstract
Description
Technical Field
[0001] This utility model relates to the field of centrifugal water pump technology, and more specifically, to a centrifugal water pump that can prevent clogging. Background Technology
[0002] Centrifugal water pumps are a common type of fluid transport equipment. They rely on the high-speed rotation of the impeller to give the fluid a large kinetic energy, and rely on the change in the cross-sectional area of the volute at the outlet of the flow channel to convert the fluid's kinetic energy into pressure energy.
[0003] In existing centrifugal water pumps, the pump is typically filled with water first. After starting, the rotating impeller drives the water in the pump to rotate at high speed. When the impeller rotates rapidly, the blades cause the medium to rotate quickly. Under the action of centrifugal force, the rotating medium flies out of the impeller. After the water in the pump is thrown out, a vacuum area is formed in the center of the impeller. This causes external liquid to enter the pump casing under atmospheric pressure, forming a continuous process of sucking in liquid and continuously giving the sucked-in liquid a certain amount of energy to discharge the liquid. However, in actual use, the following problems exist: impurities mixed in with the absorbed water flow can easily become entangled on the surface of the impeller. This affects the impeller speed and can also easily cause the water pump to become clogged, reducing the efficiency of the water pump and causing trouble for the operators. To address these problems, we have proposed a clog-resistant centrifugal water pump. Utility Model Content

[0022] (III) Beneficial Effects
[0023] Compared with the prior art, the present invention provides a centrifugal water pump that can prevent clogging, and has the following beneficial effects.
[0024] 1. This utility model uses a water flow filter plate to facilitate the filtration of absorbed water, preventing impurities from entering the inner cavity of the centrifugal water pump body and getting trapped on the impeller surface, thus improving the efficiency of the centrifugal water pump body. The screw cap facilitates the rotation of the threaded rod. Since the threads on the surface of the threaded rod and the threads in the inner cavity of the threaded sleeve are connected, the rotation of the threaded rod drives the threaded sleeve to move, which in turn drives the sliding plate to move. The sliding plate then drives the insertion rod to move, and the insertion rod limits or releases the limit on the mounting rod, facilitating the disassembly and assembly of the water flow filter plate and making it easy to clean impurities adsorbed on its surface, thereby improving the efficiency of the water flow filter plate.
[0025] 2. This utility model uses a spring to effectively utilize its own restoring elasticity to push the sliding plate to move, thereby causing the sliding plate to push the mounting rod to move. This can speed up the ejection of the mounting rod from the inner cavity of the limiting shell, improving the efficiency of disassembling the water flow filter plate. The sliding groove improves the sliding stability of the sliding plate. The limiting groove allows the slide plate to slide in its inner cavity, improving the sliding stability of the threaded sleeve. The bearing improves the rotational stability of the threaded rod.

Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. The control method can be implemented by simple programming by those skilled in the art and belongs to common knowledge in the art. It is only used without modification, so the control method and circuit connection will not be described in detail. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present utility model.
[0032] Example 1;
[0033] Please see Figure 1-4 This utility model discloses a clog-resistant centrifugal water pump, comprising a mounting base 1, a centrifugal water pump body 2 fixedly mounted on the top of the mounting base 1, a suction pipe 3 fixedly connected to the right side of the centrifugal water pump body 2, a housing 4 fixedly mounted to the right side of the suction pipe 3, limit shells 11 fixedly connected to both sides of the inner cavity of the housing 4, an adjusting shell 8 fixedly connected to the surface of the limit shell 11, a screw cap 9 movably connected to the surface of the adjusting shell 8, a threaded rod 10 fixedly connected to the back of the screw cap 9, and the right side of the threaded rod 10 penetrating to the adjusting shell 8. The inner cavity of the segment housing 8 is threadedly connected to a threaded sleeve 13. Both ends of the threaded sleeve 13 are fixedly connected to a sliding plate 15. The right side of the sliding plate 15 is fixedly connected to an insertion rod 14. The right side of the insertion rod 14 passes through the inner cavity of the limiting housing 11 and is inserted into an installation rod 16. The top of the installation rod 16 passes through the outside of the limiting housing 11 and is fixedly connected to a connecting plate 7. One side of the connecting plate 7 is fixedly connected to a water flow filter plate 12. The top of the centrifugal water pump body 2 is fixedly connected to a water outlet pipe 6. The side of the housing 4 is fixedly connected to a connecting pipe 5.
[0034] Through the above technical solution, the water flow filter plate 12 facilitates the filtration of the absorbed water flow, preventing impurities from entering the inner cavity of the centrifugal pump body 2 and getting caught on the impeller surface inside the centrifugal pump body 2, thus improving the efficiency of the centrifugal pump body 2. The screw cap 9 facilitates the rotation of the threaded rod 10. Since the threads on the surface of the threaded rod 10 and the threads in the inner cavity of the threaded sleeve 13 are connected, the rotation of the threaded rod 10 drives the threaded sleeve 13 to move, which in turn drives the sliding plate 15 to move, which in turn drives the insertion rod 14 to move. The insertion rod 14 limits or releases the installation rod 16, facilitating the disassembly and assembly of the water flow filter plate 12 and making it easy to clean the impurities adsorbed on its surface, thereby improving the efficiency of the water flow filter plate 12.
[0035] Example 2;
[0036] like Figure 4As shown, a spring 18 is fixedly connected to the bottom of the inner cavity of the limiting shell 11, and a sliding plate 17 is fixedly connected to the top of the spring 18. The top of the sliding plate 17 is in close contact with the bottom of the mounting rod 16.
[0037] Through the above technical solution, the spring 18 can effectively use its own restoring elasticity to push the sliding plate 17 to move, thereby causing the sliding plate 17 to push the mounting rod 16 to move, which can speed up the ejection of the mounting rod 16 from the inner cavity of the limiting shell 11 and improve the efficiency of disassembling the water flow filter plate 12.
[0038] Example 3;
[0039] like Figure 1-4 As shown, a groove is provided on one side of the inner cavity of the limiting shell 11, and one side of the sliding plate 17 is slidably connected to the inner cavity of the groove. An insertion hole is provided on the side of the mounting rod 16, and one side of the insertion rod 14 is inserted into the inner cavity of the insertion hole. Limiting grooves are provided at both ends of the inner cavity of the adjusting shell 8. One end of the sliding plate 15 is slidably connected to the inner cavity of the limiting groove. A bearing is fixedly connected to the right side of the inner cavity of the adjusting shell 8, and the right side of the threaded rod 10 is rotatably connected to the inner cavity of the bearing. Mounting blocks are fixedly connected to both sides of the mounting base 1, and mounting holes are provided on the surface of the mounting blocks. An insertion port is provided at the top of the inner cavity of the limiting shell 11, and both sides of the mounting rod 16 are fitted and connected to the inner wall of the insertion port.
[0040] The above technical solutions improve the sliding stability of the sliding plate 17 by means of the sliding groove, allow the sliding plate 15 to slide in its inner cavity by means of the limiting groove, improve the sliding stability of the threaded sleeve 13, and improve the rotational stability of the threaded rod 10 by means of the bearing.
[0041] The working principle of this utility model is as follows: First, when the centrifugal water pump body 2 is working, it facilitates the suction pipe 3 and connecting pipe 5 to absorb water. The water then enters the inner cavity of the housing 4 through the connecting pipe 5 and passes through the water flow filter plate 12, which filters the absorbed water to prevent impurities from entering the inner cavity of the centrifugal water pump body 2 and accumulating on the impeller surface inside the centrifugal water pump body 2, thus preventing blockage and improving the efficiency of the centrifugal water pump body 2. The filtered water is then discharged through the outlet pipe 6. However, when the water flow filter plate 12 is used for a long time, its surface easily absorbs impurities, which can clog the filter holes. The user periodically rotates the cap 9 in reverse to remove these impurities. Tighten cap 9 to facilitate the reverse rotation of threaded rod 10. Since the threads on the surface of threaded rod 10 and the threads in the inner cavity of threaded sleeve 13 are threadedly connected, when threaded rod 10 rotates, it drives threaded sleeve 13 to reset and move. Through threaded sleeve 13, it drives slide plate 15 to reset and move. Through slide plate 15, it drives insertion rod 14 to reset and move. Through the movement of insertion rod 14, it disengages from the insertion hole on the surface of mounting rod 16. At this time, the limiting pressure of mounting rod 16 is eliminated, and spring 18 automatically resets. Through spring 18, its own reset elasticity can effectively push sliding plate 17 to move, thereby causing sliding plate 17 to push mounting rod 16 out of the inner cavity of limiting shell 11. Then, the user can remove water flow filter plate 12 from the inner cavity of shell 4 for cleaning.
[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
