Description

Technical Field

[0001] This utility model relates to the field of water pump technology, specifically a water pump assembly with a cleaning structure. Background Technology

[0002] A water pump is a mechanical device used for pumping and transporting liquids. It is typically driven by an electric motor or other power source, and draws liquid from one place and pressurizes it to another by rotation or movement. The main function of a water pump is to provide pressure to deliver liquid to the required location. Water pumps can be used in various fields, including industry, agriculture, civil engineering, and construction. There are many types of water pumps, including centrifugal pumps, piston pumps, screw pumps, and submersible pumps, each with its own characteristics and applicable scenarios.

[0003] Submersible pumps are pumps installed and operating in water. During use, impurities in the water can clog the water inlet, which existing pumps cannot effectively clean or clear. When the inlet is blocked, the submersible pump requires more power to push water through. This increases the pump's load, causing it to consume more energy during operation, and may lead to overheating and damage, affecting its lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a water pump assembly with a cleaning structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a water pump assembly with a cleaning structure, comprising:

[0006] The water pump body has a connecting cylinder fixedly connected to its water inlet end, and a No. 1 water inlet hole is provided at equal intervals in the middle of the connecting cylinder;

[0007] A sliding cylinder is slidably placed inside the connecting cylinder. The sliding cylinder has a third water inlet hole in its middle. A fixing plate is fixedly connected to the middle of the sliding cylinder. A lifting part for driving the water pump body to rise and fall is fixedly connected to the top of the fixing plate. When the water pump body is not raised, the first and third water inlets are arranged vertically and are in a closed state. When the water pump body is raised, the first and third water inlets are arranged vertically and are in an open state.

[0008] The lifting slide sleeve slides to the outside of the connecting cylinder. The bottom of the lifting slide sleeve is provided with a driving part for driving the lifting slide sleeve to rise and fall, and the top of the lifting slide sleeve is provided with an elastic component.

[0009] Preferably, the pump body is provided with an outlet pipe at its end.

[0010] Preferably, a connecting sleeve is fixedly connected to the bottom of the connecting cylinder, and a limiting rod is slidably connected to the middle of the connecting sleeve, with the bottom of the limiting rod fixedly connected to the sliding cylinder.

[0011] Preferably, the lifting part is an electric push rod, the fixed end of which is fixedly connected to the water pump body, and the piston end of which is fixedly connected to the fixed plate.

[0012] Preferably, a second water inlet is provided on the outer side of the sliding cylinder and below the third water inlet.

[0013] Preferably, the bottom of the sliding cylinder is provided with an annular groove, and the driving part includes a plurality of second electromagnets and a plurality of first electromagnets. The second electromagnets correspond one-to-one with the first electromagnets.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 , 2 As shown in Figures 3 and 4, this utility model provides a technical solution: a water pump assembly with a cleaning structure, comprising: a water pump body 1, which is a submersible pump, including a motor and a pump body, the pump body including components such as an impeller, stator, and rotor, used to draw liquid from one place and press it to another place by rotation; a connecting cylinder 3 is fixedly connected to the water inlet end of the water pump body 1, and a first water inlet hole 5 is provided at equal intervals in the middle of the connecting cylinder 3; a sliding cylinder 4 is slidably placed inside the connecting cylinder 3, and a third water inlet hole is provided in the middle of the sliding cylinder 4. 15. A fixing plate 9 is fixedly connected to the middle of the sliding cylinder 4. A lifting part for driving the water pump body 1 to rise and fall is fixedly connected to the top of the fixing plate 9. When the water pump body 1 is not raised, the No. 1 water inlet 5 and the No. 3 water inlet 15 are arranged vertically and closed. When the water pump body 1 is raised, the No. 1 water inlet 5 and the No. 3 water inlet 15 are arranged vertically and open. The lifting sleeve 7 slides to the outside of the connecting cylinder 3. The bottom of the lifting sleeve 7 is provided with a driving part for driving the lifting sleeve 7 to rise and fall. The top of the lifting sleeve 7 is provided with an elastic component.

[0023] It should be noted that, in use, when the water flow decreases or stops completely, the control switch simultaneously controls the drive unit to operate. Under the repulsive force of the drive unit, the lifting sleeve 7 moves upward along the sliding cylinder 4. During this period, the lifting sleeve 7 compresses the elastic part. When the drive unit is de-energized, the elastic part drives the lifting sleeve 7 to reset. By cyclically energizing, the lifting sleeve 7 can reciprocate, thereby scraping and cleaning the outside of the sliding cylinder 4. This prevents blockage from increasing the pump load, causing it to consume more energy during operation, and potentially leading to overheating and damage to the pump. In its natural state, the connecting sleeve 16 is in contact with the fixing plate 9. The first water inlet 5 is blocked, and the connecting cylinder 3 blocks the third water inlet 15. When the blockage cannot be effectively relieved by the lifting sleeve 7, the piston rod of the lifting part is extended by the control switch. Since the fixed plate 9 is fixed to the sliding cylinder 4, under the reaction force, the lifting part drives the water pump body 1 to rise. The water pump body 1 drives the connecting cylinder 3 to slide on the outside of the sliding cylinder 4, so that the first water inlet 5 moves to the top of the sliding cylinder 4. At this time, the first water inlet 5 and the third water inlet 15 are set up vertically and are both in an open state, so that water can flow into the water pump body 1 through the first water inlet 5 and the third water inlet 15.

[0024] Please see Figure 1 , 2 As shown, the pump body 1 has an outlet pipe 2 at its end, and a connecting sleeve 16 is fixedly connected to the bottom of the connecting cylinder 3. A limit rod 10 is slidably connected to the middle of the connecting sleeve 16, and the bottom of the limit rod 10 is fixedly connected to the sliding cylinder 4.

[0025] It should be noted that the water outlet pipe 2 of this utility model is installed on the outside of the pump body and is set upward along the direction of the pump body 1 to facilitate the upward delivery of water. The limiting rod 10 is fixed to the fixing plate 9, and the connecting sleeve 16 slides on the outside of the limiting rod 10, so that when the lifting part drives the sliding cylinder 4 to rise and fall, the connecting sleeve 16 can move stably, thereby ensuring that the connecting cylinder 3 slides on the outside of the sliding cylinder 4, thereby realizing the stable lifting and lowering of the pump body 1 and ensuring the positional relationship between the first water inlet hole 5 and the third water inlet hole 15.

[0026] Please see Figure 1 , 2 As shown, the lifting part is an electric push rod 8. The fixed end of the electric push rod 8 is fixedly connected to the water pump body 1, and the piston end of the electric push rod 8 is fixedly connected to the fixed plate 9.

[0027] It should be noted that when the piston rod of the electric push rod 8 of this utility model extends, because the piston rod of the electric push rod 8 is fixedly connected to the fixed plate 9, under the reaction force, the electric push rod 8 drives the water pump body 1 to rise and fall along the sliding cylinder 4, thereby adjusting the relative position of the connecting cylinder 3 and the sliding cylinder 4, so that the No. 1 water inlet 5 and the No. 3 water inlet 15 can be switched between open and closed states as needed.

[0028] Please see Figure 3 , 4 As shown, a second water inlet 6 is provided on the outer side of the sliding cylinder 4 and below the third water inlet 15. An annular groove 13 is provided at the bottom of the sliding cylinder 4. The driving part includes multiple second electromagnets 14 and multiple first electromagnets 12. The second electromagnets 14 and the first electromagnets 12 correspond one-to-one. The second electromagnets 14 are fixed in the annular groove 13, and the first electromagnets 12 are fixed in the bottom of the lifting sleeve 7. The elastic component is a return spring 11, which is sleeved on the outer side of the limit rod 10 and located between the fixed plate 9 and the lifting sleeve 7.

[0029] It should be noted that when the first electromagnet 12 and the second electromagnet 14 are energized, their magnetic poles are the same. It is necessary to control the lifting sleeve 7 to clean the sliding cylinder 4. The first electromagnet 12 and the second electromagnet 14 are energized at the same time. Under the action of repulsion, the lifting sleeve 7 moves upward along the limit rod 10. While the lifting sleeve 7 moves upward, it compresses the limit rod 10. When the first electromagnet 12 and the second electromagnet 14 are de-energized, the reset spring 11 pushes the lifting sleeve 7 to reset. This process is repeated to achieve the scraping and cleaning of the sliding cylinder 4 by the lifting sleeve 7.
