Description

Technical Field

[0001] This utility model relates to the field of water pump technology, specifically to a suspended submersible pump. Background Technology

[0002] Submersible pumps are essential equipment for deep well water extraction. During operation, the entire unit is submerged in water to extract groundwater to the surface. They are suitable for various applications including domestic water supply, mine rescue, industrial cooling, farmland irrigation, seawater lifting, and ship ballast adjustment. While previous submersible pumps could detect water levels and automatically control their start and stop, they had limitations. In some rivers where the riverbed and water depth are unknown, large amounts of silt may accumulate, causing the pump to enter the silt and potentially damage the motor, posing a certain risk.

[0003] To solve this technical problem, the prior art provides a suspended submersible pump, CN218624680U, which uses a rubber air bladder and a micro air pump to make the body float on the water surface, making it more convenient to retrieve the submersible pump. The air pressure in the rubber air bladder can be controlled by a solenoid valve to keep the body suspended in the water, preventing the submersible pump from sinking to the bottom of the river and entering the silt.

[0004] However, there may be some technical problems during its use. For example, when the device is in use, one end of spring three pushes steel ball three to press the steel ball three into the vent hole to close the vent hole. Protrusion two presses against the other end of the spring to prevent spring three from disengaging from the vent hole. When the solenoid valve is open, it prevents water from flowing back into the rubber air bladder due to insufficient air pressure, which would prevent the submersible pump from floating. However, since the device uses a spring and steel ball component as the mechanism to prevent water from flowing back, and the steel ball only relies on the spring for reset, the stability of the steel ball during use may be low. In the event of an accident during use, it may not be able to return to the vent hole, affecting the normal use of the device. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a suspended submersible pump that not only allows workers to easily inflate the rubber airbag to suspend the pump body in water, but also facilitates the expulsion of air from the rubber airbag, improving the stability of the rubber airbag during air expulsion and preventing any impact on the normal operation of the device.

[0006] This utility model is achieved through the following technical solution: a suspended submersible pump is provided, including a pump body and a float connected to the pump body via a control circuit. A rubber air bladder is fixed on the outer wall of the pump body. A miniature air pump is installed inside the float. An air inlet pipe is installed at the air inlet of the miniature air pump, and the air inlet pipe passes upward through the float. A one-way valve is installed inside the air inlet pipe. An air outlet pipe is installed at the air outlet of the miniature air pump, and the air outlet pipe passes downward through the float and communicates with the rubber air bladder. An overflow valve is installed on the outer wall of the rubber air bladder. A connecting pipe communicating with the inside of the rubber air bladder is fixed on the outer wall of the rubber air bladder. A solenoid valve located inside the rubber air bladder is installed on the connecting pipe. Two annular plates located on one side of the output end of the solenoid valve and distributed along the length of the connecting pipe are fixed to the inner wall of the connecting pipe. A sliding block is pressed against an annular plate adjacent to the solenoid valve in a sealing sliding connection. The sliding block is fixed to the annular plate away from the solenoid valve by a first spring. A square through hole is opened on the outer wall of the sliding block. A through groove is opened on the inner circumferential surface of the square through hole. Two rotating plates are arranged in the square through hole along the width direction of the connecting pipe. A first pressure plate and a second pressure plate are arranged between the two rotating plates. The first pressure plate presses on the second pressure plate. A reset mechanism is provided in the through groove to press the rotating plate against the side wall of the through groove away from the solenoid valve. The first pressure plate and the second pressure plate are fixed to the two rotating plates respectively. The rotating plates, the first pressure plate and the second pressure plate all extend laterally along the height direction of the connecting pipe and are sealed and fitted to the bottom of the through groove. A top rod is provided on the side of the second pressure plate away from the first pressure plate, which presses on the outer wall of the rotating plate and is fixed to the annular plate away from the solenoid valve.

[0007] In use, this invention comprises a pump body and a float connected to the pump body via a control circuit. A rubber air bladder is fixed to the outer wall of the pump body. A miniature air pump is installed inside the float. An air inlet pipe is installed at the air inlet of the miniature air pump, extending upward through the float and containing a one-way valve. An air outlet pipe is installed at the air outlet of the miniature air pump, extending downward through the float and communicating with the rubber air bladder. An overflow valve is installed on the outer wall of the rubber air bladder. A connecting pipe communicating with the inside of the rubber air bladder is fixed to the outer wall of the rubber air bladder. A solenoid valve located inside the rubber air bladder is installed on the connecting pipe. Two annular plates are fixed to the inner wall of the connecting pipe, located on one side of the output end of the solenoid valve and distributed along the length of the connecting pipe. A sealing sliding contact is formed on the inner wall of the connecting pipe, pressing against the annular plate adjacent to the solenoid valve. The slider is fixed to the annular plate away from the solenoid valve by a first spring. A square through hole is opened on the outer wall of the slider, and a through groove is opened on the inner circumferential surface of the square through hole. Two rotating plates are arranged in the square through hole along the width of the connecting pipe. A first pressure plate and a second pressure plate are arranged between the two rotating plates. The first pressure plate presses on the second pressure plate. A reset mechanism is provided in the through groove to press the rotating plate against the side wall of the through groove away from the solenoid valve. The first pressure plate and the second pressure plate are fixed to the two rotating plates respectively. The rotating plates, the first pressure plate and the second pressure plate all extend laterally along the height of the connecting pipe and are sealed to the bottom of the through groove. A top rod is provided on the side of the second pressure plate away from the first pressure plate, which presses on the outer wall of the rotating plate and is fixed to the annular plate away from the solenoid valve. When using the device, the pump body needs to be... The rubber airbag is placed in the water, and the miniature air pump floats on the surface with the help of a float. The miniature air pump is then activated, drawing air through the air inlet and outlet and sending it into the rubber airbag to inflate it. During this process, the one-way valve is open and the solenoid valve is closed. After a certain amount of air is inflated, the rubber airbag will suspend the pump body in the water. At this point, both the one-way valve and the solenoid valve are closed. The overflow valve not only facilitates the discharge of excess air from the rubber airbag, preventing it from rupturing due to excessive pressure, but also prevents water from entering the rubber airbag during the discharge process. Then... The pump body can draw water to the surface. After the water is drawn, the pump body is removed from the water. Then, the solenoid valve is opened, allowing air from the rubber bladder to enter the connecting pipe. This causes the slider in the connecting pipe to move away from the solenoid valve under the pressure of the air in the rubber bladder, disengaging from the ring plate adjacent to the solenoid valve. This compresses the first spring on the ring plate away from the solenoid valve, causing the push rod fixed to the ring plate to push one of the rotating plates to rotate towards the solenoid valve within the square through hole. This prevents one of the rotating plates from pressing against the side wall of the through groove away from the solenoid valve, and drives the reset mechanism of the through groove. Consequently, the second pressure plate also rotates towards the solenoid valve within the square through hole along with one of the rotating plates, preventing the first pressure plate from pressing against the second pressure plate.This allows air inside the rubber bladder to escape to the outside through the connecting pipe, square through-hole, and inner hole of the ring plate. After the air is expelled from the rubber bladder, the first spring drives the slider in the connecting pipe back to its initial position, causing the slider to press back onto the ring plate adjacent to the solenoid valve. Simultaneously, one of the rotating plates, driven by the reset mechanism, presses back onto the side wall of the through groove away from the solenoid valve. The first pressure plate then presses back onto the second pressure plate. This not only facilitates the operator inflating the rubber bladder, allowing the pump to suspend in water, but also makes it easier to expel air from the bladder, improving its stability during exhaust and preventing disruption to the normal operation of the device.

[0008] Preferably, the overflow valve includes an overflow block fixedly connected to the outer wall of the rubber airbag. An overflow hole is provided on the outer wall of the overflow block. A first annular plate is fixedly connected to the inner wall of the overflow hole. A steel ball located outside the first annular plate is provided in the overflow hole. The steel ball extends into the inner hole of the first annular plate and presses against the outer wall of the first annular plate. A second annular plate is provided in the overflow hole on the side of the steel ball away from the first annular plate. A sliding groove is provided on the inner wall of the overflow hole on the side of the steel ball away from the first annular plate. A movable block fixedly connected to the outer circumference of the second annular plate is provided in the sliding groove. A threaded rod is threaded in the overflow hole. The threaded rod presses against the outer wall of the second annular plate. The second annular plate and the steel ball are fixedly connected by a second spring. An air leakage hole is provided on the outer wall of the threaded rod. The overflow valve includes an overflow block fixed to the outer wall of the rubber air bladder. An overflow hole is formed on the outer wall of the overflow block. A first annular plate is fixed to the inner wall of the overflow hole. A steel ball is placed inside the overflow hole, located outside the first annular plate. The steel ball extends into the inner hole of the first annular plate and presses against its outer wall. A second annular plate is located inside the overflow hole, on the side of the steel ball furthest from the first annular plate. A groove is formed on the inner wall of the overflow hole, on the side of the steel ball furthest from the first annular plate. A movable block fixed to the outer circumference of the second annular plate is placed in the groove. A threaded rod is threaded into the overflow hole, pressing against the outer wall of the second annular plate. The second annular plate and the steel ball are fixed together by a second spring. A leakage hole is formed on the outer wall of the threaded rod. During use, when the air pressure inside the rubber air bladder is high, excess air leaks out. The air inside the rubber bladder pushes the steel ball in the overflow hole away from the first annular plate, compressing the second spring on the second annular plate. This causes the steel ball to dislodge from the inner hole of the first annular plate and no longer press against its outer wall. The air inside the rubber bladder then escapes to the outside through the leak holes in the first and second annular plates and the threaded rod. Rotating the threaded rod adjusts its position within the overflow hole. In conjunction with the second spring, the threaded rod drives the second annular plate's moving block within the groove, adjusting the distance between the second and first annular plates. This, in turn, adjusts the maximum pressure the overflow valve can accommodate. Tightening the spring increases the pressure required to open the overflow valve, while loosening the spring decreases the pressure.

[0009] Preferably, the reset mechanism includes a torsion spring shaft disposed within the through groove and fixedly connected to the side wall of the rotating plate away from the square through hole. The torsion spring shaft facilitates not only the rotation of the rotating plate within the square through hole but also allows the rotating plate to press against the side wall of the through groove away from the solenoid valve.

[0010] Preferably, the ring plate, slider, square through hole, and first spring are coaxially arranged. By making the ring plate, slider, square through hole, and first spring coaxial, the stability of the internal components of the connecting pipe can be improved during use.

[0011] Preferably, rubber gaskets are fixedly attached to both the side wall of the first pressure plate facing the solenoid valve and the side wall of the second pressure plate away from the solenoid valve. By fixing rubber gaskets to both the side wall of the first pressure plate facing the solenoid valve and the side wall of the second pressure plate away from the solenoid valve, the sealing effect of the device during use can be improved.

[0012] The beneficial effects of this utility model are as follows: A pump body and a float connected to the pump body via a control circuit are configured. A rubber air bladder is fixed on the outer wall of the pump body. A miniature air pump is installed inside the float. An air inlet pipe is installed at the air inlet of the miniature air pump, extending upwards through the float. A one-way valve is installed inside the air inlet pipe. An air outlet pipe is installed at the air outlet of the miniature air pump, extending downwards through the float and communicating with the rubber air bladder. An overflow valve is installed on the outer wall of the rubber air bladder. A connecting pipe communicating with the inside of the rubber air bladder is fixed on the outer wall of the rubber air bladder. A solenoid valve located inside the rubber air bladder is installed on the connecting pipe. Two annular plates located on one side of the output end of the solenoid valve and distributed along the length of the connecting pipe are fixedly connected to the inner wall of the connecting pipe. A sealing sliding contact is formed on the inner wall of the connecting pipe, pressing against the annular plate adjacent to the solenoid valve. The slider is fixed to the annular plate away from the solenoid valve by a first spring. A square through hole is opened on the outer wall of the slider, and a through groove is opened on the inner circumferential surface of the square through hole. Two rotating plates are arranged in the square through hole along the width of the connecting pipe. A first pressure plate and a second pressure plate are arranged between the two rotating plates. The first pressure plate presses on the second pressure plate. A reset mechanism is provided in the through groove to press the rotating plate against the side wall of the through groove away from the solenoid valve. The first pressure plate and the second pressure plate are fixed to the two rotating plates respectively. The rotating plates, the first pressure plate and the second pressure plate all extend laterally along the height of the connecting pipe and are sealed to the bottom of the through groove. A top rod is provided on the side of the second pressure plate away from the first pressure plate, which presses on the outer wall of the rotating plate and is fixed to the annular plate away from the solenoid valve.

At this point, both the one-way valve and the solenoid valve are closed. The overflow valve not only facilitates the discharge of excess air from the rubber airbag, preventing it from rupturing due to excessive pressure, but also prevents water from entering the rubber airbag during the discharge process. Then... The pump body can draw water to the surface. After the water is drawn, the pump body is removed from the water. Then, the solenoid valve is opened, allowing air from the rubber bladder to enter the connecting pipe. This causes the slider in the connecting pipe to move away from the solenoid valve under the pressure of the air in the rubber bladder, disengaging from the ring plate adjacent to the solenoid valve. This compresses the first spring on the ring plate away from the solenoid valve, causing the push rod fixed to the ring plate to push one of the rotating plates to rotate towards the solenoid valve within the square through hole. This prevents one of the rotating plates from pressing against the side wall of the through groove away from the solenoid valve, and drives the reset mechanism of the through groove. Consequently, the second pressure plate also rotates towards the solenoid valve within the square through hole along with one of the rotating plates, preventing the first pressure plate from pressing against the second pressure plate.This allows air inside the rubber bladder to escape to the outside through the connecting pipe, square through-hole, and inner hole of the ring plate.

[0023] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0024] like Figures 1-8 The suspended submersible pump of this utility model includes a pump body 2 and a float 1 connected to the pump body 2 via a control circuit 3. A rubber air bladder 4 is fixed on the outer wall of the pump body 2. A miniature air pump 10 is installed inside the float 1. An air inlet 8 of the miniature air pump 10 is equipped with an air inlet pipe 12, which extends upward through the float 1. A one-way valve 11 is installed inside the air inlet pipe 12. An air outlet 9 of the miniature air pump 10 is equipped with an air outlet pipe 5, which extends downward through the float. 1. It is connected to the rubber airbag 4. An overflow valve is provided on the outer wall of the rubber airbag 4. A connecting pipe 14 communicating with the inside of the rubber airbag 4 is fixed on the outer wall of the rubber airbag 4. A solenoid valve 7 located inside the rubber airbag 4 is provided on the connecting pipe 14. Two annular plates 15 located on the output end side of the solenoid valve 7 and distributed along the length of the connecting pipe 14 are fixed to the inner wall of the connecting pipe 14. A sealing sliding contact is provided on the inner wall of the connecting pipe 14, pressing against the annular plate 15 adjacent to the solenoid valve 7. The slider 25 is fixed to the annular plate 15 away from the solenoid valve 7 by a first spring 17. A square through hole 27 is provided on the outer wall of the slider 25. A through groove 29 is provided on the inner circumferential surface of the square through hole 27. Two rotating plates 28 are provided in the square through hole 27, which are distributed along the width direction of the connecting pipe 14. A first pressure plate 33 and a second pressure plate 34 are provided between the two rotating plates 28. The first pressure plate 33 presses on the second pressure plate 34. A reset mechanism is provided in the groove 29 to press the rotating plate 28 against the side wall of the groove 29 away from the solenoid valve 7. The first pressure plate 33 and the second pressure plate 34 are respectively fixed to the two rotating plates 28. The rotating plate 28, the first pressure plate 33 and the second pressure plate 34 all extend laterally along the height direction of the connecting pipe 14 and are sealed and fitted to the bottom of the groove 29. The second pressure plate 34 is provided with a top rod 16 on the side away from the first pressure plate 33, which presses against the outer wall of the rotating plate 28 and is fixed to the ring plate 15 away from the solenoid valve 7.

[0025] The overflow valve includes an overflow block 24 fixedly connected to the outer wall of the rubber airbag 4. An overflow hole 19 is provided on the outer wall of the overflow block 24. A first annular plate 23 is fixedly connected to the inner wall of the overflow hole 19. A steel ball 22 located outside the first annular plate 23 is provided in the overflow hole 19. The steel ball 22 extends into the inner hole of the first annular plate 23 and presses against the outer wall of the first annular plate 23. A second annular plate 20 located on the side of the steel ball 22 away from the first annular plate 23 is provided in the overflow hole 19. An overflow hole 19 has a groove 32 on its inner wall, located on the side of the steel ball 22 away from the first annular plate 23. A movable block 31, fixed to the outer circumference of the second annular plate 20, is installed in the groove 32. A threaded rod 18 is threaded into the overflow hole 19, pressing against the outer wall of the second annular plate 20. The second annular plate 20 and the steel ball 22 are fixed together by a second spring 21. An air leakage hole 30 is provided on the outer wall of the threaded rod 18. During use, when the rubber airbag 4... The internal air pressure is relatively high. Excess air in the rubber airbag 4 will push the steel ball 22 in the overflow hole 19 to move away from the first annular plate 23 and compress the second spring 21 on the second annular plate 20. This causes the steel ball 22 to come out of the inner hole of the first annular plate 23 and no longer press against the outer wall of the first annular plate 23. As a result, the air in the rubber airbag 4 can be discharged to the outside through the inner hole of the first annular plate 23, the inner hole of the second annular plate 20 and the air leakage hole 30 in the threaded rod 18. By rotating the threaded rod 18, the position of the threaded rod 18 in the overflow hole 19 can be adjusted. And through cooperation with the second spring 21, the threaded rod 18 can drive the second annular plate 20 to drive the movable block 31 to move in the slide groove 32. This adjusts the distance between the second annular plate 20 and the first annular plate 23, and thus adjusts the maximum pressure value that the overflow valve can accommodate. When the spring is tightened, the pressure to open the overflow valve is greater. When the spring is loosened, the pressure to open the overflow valve is smaller. The reset mechanism includes a torsion spring shaft 26 disposed within the through groove 29 and fixedly connected to the side wall of the rotating plate 28 away from the square through hole 27. The torsion spring shaft 26 facilitates the rotation of the rotating plate 28 within the square through hole 27 and also allows the rotating plate 28 to press against the side wall of the through groove 29 away from the solenoid valve 7. By coaxially aligning the ring plate 15, slider 25, square through hole 27, and first spring 17, the stability of the internal components of the connecting pipe during use is improved. Rubber pads 13 are fixedly connected to both the side wall of the first pressure plate 33 facing the solenoid valve 7 and the side wall of the second pressure plate 34 away from the solenoid valve 7, improving the sealing effect of the device during use. The air inlet pipe 12 is embedded in the control circuit 3, which connects the miniature air pump 10 to the rubber airbag 4. A winding device 6 is located inside the rubber airbag 4 to wind up excess control circuitry 3, preventing it from tangling with the submersible pump and reducing the risk of damage to the control circuitry 3.

[0026] Combined with appendix Figure 1-8The method of using this utility model is as follows: First, the pump body 2 and the rubber air bag 4 need to be placed in water, and the micro air pump 10 needs to float on the water surface under the action of the float ball 1. Then, the micro air pump 10 is started, so that the micro air pump 10 draws air through the air inlet pipe 12 and the air inlet 8 of the micro air pump 10, and sends it into the rubber air bag 4 through the air outlet 9 and the air outlet pipe 5, thereby inflating the rubber air bag 4. During this process, the one-way valve 11 is in the open state and the solenoid valve 7 is in the closed state. After the rubber air bag 4 is inflated with a certain amount of air, the rubber air bag 4 will drive the pump body 2 to suspend. In the water, the one-way valve 11 and the solenoid valve 7 are both closed. The overflow valve not only facilitates the discharge of excess air from the rubber bladder 4, preventing it from rupturing due to excessive pressure, but also prevents water from entering the bladder 4 during the discharge process. The pump 2 then pumps the water to the surface. After pumping, the pump 2 is removed from the water, and the solenoid valve 7 is opened, allowing air from the rubber bladder 4 to enter the connecting pipe 14. This causes the slider 25 within the connecting pipe 14 to move away from the rubber bladder 4 under the influence of the air. The solenoid valve 7 moves in the direction of movement and disengages from the annular plate 15 adjacent to it. This compresses the first spring 17 on the annular plate 15 away from the solenoid valve 7, causing the push rod 16, fixed to the annular plate 15 away from the solenoid valve 7, to push one of the rotating plates 28 to rotate around the torsion spring shaft 26 in the square through-hole 27 towards the solenoid valve 7. This compresses the torsion spring shaft 26 in the through-slot 29, causing one of the rotating plates 28 to no longer press against the side wall of the through-slot 29 away from the solenoid valve 7. Consequently, the second pressure plate 34, along with one of the rotating plates 28, also rotates in the square through-hole 27 towards the solenoid valve 7, causing the first... The rubber pad 13 of the first pressure plate 33 no longer presses on the rubber pad 13 of the second pressure plate 34, so that the air in the rubber airbag 4 is discharged to the outside through the connecting pipe, the square through hole 27 and the inner hole of the ring plate 15. After the air is discharged from the rubber airbag 4, the first spring 17 will drive the slider 25 in the connecting pipe 14 to return to the initial position, so that the slider 25 presses on the ring plate 15 adjacent to the solenoid valve 7 again, and one of the rotating plates 28 is pressed on the side wall of the through groove 29 away from the solenoid valve 7 under the drive of the torsion spring shaft 26. The rubber pad 13 of the first pressure plate 33 no longer presses on the rubber pad 13 of the second pressure plate 34.
