Description

Technical Field

[0001] This invention relates to the field of electric pump technology, and more particularly to a compact, high-lift electric pump device. Background Technology

[0002] An electric pump is a pump device that generates a high-pressure head by electrically driving an impeller or plunger, enabling the transport of fluids over long distances, at high altitudes, or under high resistance conditions.

[0003] Existing devices of this type suffer from high pressure, which reduces the lifespan of internal pump components. For example, Chinese Patent Publication No. CN117703780A discloses a high-lift water pump that includes an inlet pump and a outlet pump, both driven by a dual-shaft motor. The outlet of the inlet pump is connected to the inlet of the outlet pump, thus increasing the final head. However, connecting the two pumps in series subjects the outlet pump to higher pressure, which reduces the lifespan of internal components. Therefore, this application proposes a compact high-lift electric pump device. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a compact, high-lift electric pump device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0009] Preferably, the heat dissipation mechanism includes a mounting plate, a mounting box, a liquid extraction box, heat dissipation fins, a heat dissipation motor, a linkage rod, a drain plate, a reciprocating lead screw, an inclined block, a fan, a bevel gear set, a belt drive set, a cooling box, a rotating shaft, and a base plate;

[0010] The mounting plate and mounting box are fixedly connected to the heat dissipation fins. An inlet pipe is fixedly connected to the pump housing and is also fixedly connected to the liquid extraction box. The cooling motor is fixedly connected to the outer wall of the cooling box.

[0011] Preferably, the output shaft of the cooling motor is also fixedly connected to a reciprocating lead screw, the linkage rod is fixedly connected to multiple sprue plates, the reciprocating lead screw is assembled with an inclined block, the sprue plates are arranged between multiple cooling fins, and the fan is fixedly connected to a rotating shaft.

[0012] Preferably, the bevel gear set consists of a pair of meshing bevel gears, the belt drive set consists of a pair of pulleys and a drive belt, the cooling box is fixedly connected inside the mounting box, and the rotating shaft is rotatably connected to the base plate.

[0013] Preferably, one of the bevel gears in the bevel gear set is fixedly connected to the output shaft of the motor, and the other bevel gear in the bevel gear set is fixedly connected to the rotating shaft.

[0014] Preferably, one pulley in the belt drive assembly is fixedly connected to the shaft, and the other pulley in the belt drive assembly is fixedly connected to the fan.

[0015] Preferably, the shock absorption mechanism includes a compressed air tank, an air inlet pipe, an air outlet pipe, an air pump, a mounting plate, a throttling piston, a hydraulic check valve, a pressure supply plate, a pressure supply piston, a solenoid valve, and a hydraulic plate.

[0016] The air pump is fixedly connected inside the compressed air tank, the hydraulic plate is fixedly connected to the compressed air tank, the air inlet pipe is connected to the air inlet end of the pressure supply piston, and the air outlet pipe is fixedly connected to the air outlet end of the pressure supply piston.

[0017] Preferably, the air inlet ends of both the air inlet pipe and the air outlet pipe are fixedly connected to the solenoid valve.

[0018] Preferably, the mounting plate is fixedly connected to the output rod of the throttling piston, and the pressure plate is fixedly connected to the output shaft of the pressure supply piston.

[0019] Preferably, there are two hydraulic check valves with opposite liquid inlet directions. The hydraulic check valves are installed inside the hydraulic plate. A device housing is fixedly connected to the base plate. A liquid extraction pipe is fixedly connected to the liquid extraction box. A connecting groove is opened on the heat dissipation fins. An air inlet pipe is also fixedly connected to the heat dissipation fins.

[0020] The present invention has the following beneficial effects:

[0021] 1. By setting up a pressurization mechanism, the pressure bearing position of this device and the liquid outlet one-way valve is changed, so that the pressure bearing position is changed from the original pump bearing pressure to the liquid outlet 4 bearing pressure, thereby avoiding the problem of reducing the life of internal pump parts due to the high pressure required for high head.

[0022] 2. By setting up a heat dissipation mechanism, the heat generated by the motor inside the device during operation can be drawn out of the device. At the same time, in conjunction with the heat dissipation fins, the heat in the outside air can be transferred to the flowing liquid through the heat dissipation fins, thereby cooling the outside air flowing into the device and improving the heat dissipation effect.

[0023] 3. By setting up a shock absorption mechanism, when the motor in this device is running, the vibration generated by the motor can be squeezed out by the hydraulic oil in the throttling piston to achieve the effect of shock absorption. That is, when the fluid is squeezed out through the hole on the throttling piston, due to the narrow channel inside, the fluid cannot pass through the hole on the throttling piston instantly, so it can only pass through slowly, thereby releasing the energy generated by the vibration.

Detailed Implementation

[0042] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0043] Example 1:

[0044] A compact high-lift electric pump device includes a heat dissipation mechanism, a pressure boosting mechanism, and a shock absorption mechanism. The pressure boosting mechanism includes an outlet 4, a pump housing 5, a second pressure boosting flow pipe 33, a first connecting ring 20, a pressure boosting piston 24, a first pressure boosting flow pipe 21, a second connecting ring 22, an outlet check valve 36, a motor 14, a linkage shaft 23, a turntable 37, a swashplate 38, a suction rod 39, an outlet block 40, a return spring 41, a blocking ball 43, a blocking spring 42, a connecting plate 28, and an eccentric wheel 16.

[0045] The outlet 4 is fixedly connected to the connecting plate 28, the pump housing 5 is rotatably and sealingly connected to the linkage shaft 23, the second booster flow pipe 33 is fixedly connected to the first connecting ring 20, the first connecting ring 20 is fixedly connected to the output rod of multiple booster pistons 24, the outlet end of the booster piston 24 is fixedly connected to one end of the first booster flow pipe 21, the other end of the first booster flow pipe 21 is fixedly connected to the second connecting ring 22, the second connecting ring 22 is fixedly connected to the connecting plate 28, and the liquid check valve 36 is installed on the connecting plate 28.

[0046] The output shaft of motor 14 is fixedly connected to linkage shaft 23, turntable 37 is fixedly connected to linkage shaft 23, turntable 37 is in contact with swashplate 38, limit sleeve 51 is fixedly connected inside swashplate 38, one end of the output shaft of suction rod 39 is set inside limit sleeve 51, suction rod 39 is slidably sealed to discharge block 40, return spring 41 is fixedly connected to suction rod 39, and blocking spring 42 and blocking ball 43 are fixedly connected.

[0047] refer to Figure 2 and Figure 3 The bevel gear set 13 consists of two meshing bevel gears, one of which is fixedly connected to the output shaft of the motor 14, and the other is fixedly connected to the rotating shaft 6. Therefore, when one bevel gear rotates, the other bevel gear will also rotate, thereby realizing the operation of the bevel gear set 13.

[0048] Since one of the bevel gears is fixedly connected to the rotating shaft 6, the operation of the bevel gear set 13 will cause the rotating shaft 6 to rotate. Because the eccentric wheel 16 is fixedly connected to the rotating shaft 6, the eccentric wheel 16 will also rotate. The eccentric wheel 16 is eccentrically positioned; see reference [link / reference] Figure 3 The eccentric wheel 16 is in contact with the first connecting ring 20. Therefore, when the eccentric wheel 16 rotates eccentrically, it pushes the first connecting ring 20 to move reciprocally. This, in turn, drives the output rod of the booster piston 24 to move reciprocally. A reset spring is installed inside the booster piston 24. One end of the spring is fixedly connected to the output shaft of the booster piston 24, and the other end is fixedly connected to the inside of the cylinder of the booster piston 24. Therefore, the output shaft of the pressure supply piston 47 can be reset.

[0049] refer to Figure 11 The first booster flow pipe is connected to the second connecting ring 22 and the booster piston 24. The first connecting ring 20 is also connected to the second booster flow pipe 33, which is hollow inside. The second booster flow pipe 33 is connected to the liquid extraction box 7. Therefore, when the output shaft of the booster piston 24 reciprocates, the booster piston 24 will draw a portion of the liquid from the liquid extraction box 7 and inject it into the first booster flow pipe 21, which is then injected into the second connecting ring 22. This increases the flow rate at the liquid outlet 4, thereby increasing the pressure at the liquid outlet 4.

[0050] Simultaneously, the rotation of the output shaft of motor 14 will also drive the linkage shaft 23 to rotate. (See reference) Figure 12 The rotation of the linkage shaft 23 will cause the turntable 37 to rotate as well. Since the turntable 37 is in contact with the swashplate 38 and the turntable 37 is inclined, when the turntable 37 rotates, its inclined surface rotates, which in turn pushes the swashplate 38 to move back and forth, causing it to draw liquid from the extraction box 7 through the liquid inlet pipe 25. (See reference...) Figure 12The extracted liquid will pass through the outlet block 40 into the outlet check valve 36, and finally into the outlet 4. (Reference) Figure 13 A hole is made on the suction rod 39, and a blocking ball 43 is installed in the hole to prevent liquid backflow. Behind the blocking ball 43 is a blocking spring 42, which is used to reset the blocking ball 43. The reset spring 41 is used to reset the suction rod 39.

[0051] When liquid enters the pumping rod 39 through the hole, the liquid will first press the blocking ball 43 towards the blocking spring 42, causing the blocking spring 42 to be compressed, thereby opening the hole. When liquid backflow occurs, because the hole is stepped, the blocking ball 43 will block the outlet of the hole, preventing the liquid from flowing back.

[0052] Example 2:

[0053] The heat dissipation mechanism includes a mounting plate 3, a mounting box 27, a liquid extraction box 7, heat dissipation fins 8, a heat dissipation motor 26, a linkage rod 29, a drain plate 30, a reciprocating lead screw 31, an inclined block 32, a fan 50, a bevel gear set 13, a belt drive set 15, a cooling box 9, a rotating shaft 6, and a base plate 2. The mounting plate 3 and the mounting box 27 are fixedly connected. The mounting plate and the heat dissipation fins 8 are fixedly connected. An inlet pipe 25 is fixedly connected to the pump housing 5. The inlet pipe 25 is also fixedly connected to the liquid extraction box 7. The heat dissipation motor 26 is fixedly connected to the outer wall of the cooling box 9.

[0054] The output shaft of the cooling motor 26 is also fixedly connected to the reciprocating lead screw 31, the linkage rod 29 is fixedly connected to multiple heat dissipation plates 30, the reciprocating lead screw 31 is assembled with the inclined block 32, the heat dissipation plates 30 are arranged between multiple heat dissipation fins 8, and the fan 50 is fixedly connected to the rotating shaft 6.

[0055] The bevel gear set 13 consists of a pair of meshing bevel gears, the belt drive set 15 consists of a pair of pulleys and a drive belt, the cooling box 9 is fixedly connected inside the mounting box 27, and the rotating shaft 6 is rotatably connected to the base plate 2.

[0056] One of the bevel gears in the bevel gear set 13 is fixedly connected to the output shaft of the motor 14, and the other bevel gear in the bevel gear set 13 is fixedly connected to the rotating shaft 6. One of the pulleys in the belt drive set 15 is fixedly connected to the rotating shaft 6, and the other pulley in the belt drive set 15 is fixedly connected to the fan 50.

[0057] When the device is in operation, the motor 14 will generate heat, and when the liquid flows through the liquid extraction box 7, the heat sink 8 will carry away the heat from the heat sink 8 because the heat sink 8 is fixedly connected to the liquid extraction box 7. The heat sink 8 is fixedly connected to the air inlet pipe 35, and the air outlet of the device housing 1 is equipped with a fan 50, which is fixedly connected to one pulley of the belt drive assembly 15. The two pulleys transmit power through the drive belt.

[0058] refer to Figure 2 When the output shaft of motor 14 rotates, since the bevel gear set 13 consists of a pair of meshing bevel gears, when one bevel gear rotates, the other bevel gear will also rotate, thereby causing the shaft 6 to rotate. A pulley from the belt drive assembly 15, an eccentric pulley 16, and a bevel gear from the bevel gear set 13 are fixedly connected to the shaft 6. Therefore, when the shaft 6 rotates, the belt drive assembly 15 will operate. Because the fan 50 is rotatably connected to the device housing 1 and fixedly connected to another pulley, the fan 50 will rotate to draw external air into the device. Before entering the device housing 1, the heat of the external air is first absorbed by the heat dissipation fins 8, becoming cooler air, which then provides cooling for the motor 14 before being exhausted from the device.

[0059] Also refer to Figures 4 to 7 When the cooling motor 26 is turned on, its output shaft is fixedly connected to the reciprocating lead screw 31. Therefore, when the cooling motor 26 is running, the reciprocating lead screw 31 will rotate. (Refer to...) Figure 7 The inclined block 32 is mounted on the reciprocating screw 31 and moves back and forth as the reciprocating screw 31 rotates. Its upper end is an inclined surface, which corresponds to the inclined surface at the lower end of the sprue plate 30. When the inclined block 32 moves back and forth, it will contact the inclined surface at the lower end of the sprue plate 30, thereby causing the sprue plate 30 to move up and down back and forth.

[0060] The lower end of the drain plate 30 is also a slope, and both ends of the drain plate 30 are slidably connected to the inner wall of the cooling box 9. Multiple drain plates 30 are fixedly connected by a linkage rod 29. A vacuum is drawn inside the cooling box 9, and a small amount of water is injected. Because the inside of the cooling box 9 is a vacuum, the boiling point of the water inside will be lower. At the same time, the drain plates 30 are arranged between the heat dissipation fins 8, and the heat dissipation fins 8 extend into the interior of the cooling box 9.

[0061] As the drain plate 30 moves downwards, some water enters through its grooves. As it moves upwards, the holes on both sides of the drain plate 30 allow the water to leak out, flowing onto the heat dissipation fins 8. The heat dissipation fins 8 have multiple grooves to increase their contact area with the water. When external temperature is transferred through the heat dissipation fins 8 to the portion located in the cooling box 9, the water remaining on the heat dissipation fins 8 evaporates to carry away heat, further improving the heat dissipation effect. It should be noted that the cooling box 9 is sealed, preventing the water inside from corroding the internal components of the device.

[0062] Example 3:

[0063] The shock absorption mechanism includes a compressed air tank 11, an inlet pipe 18, an outlet pipe 19, an air pump 17, a mounting plate 44, a throttle piston 46, a hydraulic check valve 45, a pressure supply plate 48, a pressure supply piston 47, a solenoid valve 49, and a hydraulic plate 12. The air pump 17 is fixedly connected inside the compressed air tank 11. The hydraulic plate 12 is fixedly connected to the compressed air tank 11. The inlet pipe 18 is connected to the inlet end of the pressure supply piston 47, and the outlet pipe 19 is fixedly connected to the outlet end of the pressure supply piston 47. The inlet ends of both the inlet pipe 18 and the outlet pipe 19 are fixedly connected to the solenoid valve 49.

[0064] Mounting plate 44 is fixedly connected to the output rod of throttling piston 46, and pressure plate 48 is fixedly connected to the output shaft of pressure piston 47. There are two hydraulic check valves 45, and the liquid inlet directions of the two hydraulic check valves 45 are opposite. Device housing 1 is fixedly connected to base plate 2, liquid extraction pipe 10 is fixedly connected to liquid extraction box 7, a connecting groove 34 is opened on heat dissipation fin 8, and an air inlet pipe 35 is also fixedly connected to heat dissipation fin 8.

[0065] refer to Figure 14 , Figure 15 , Figure 16 The motor 14 is mounted on the mounting plate 44, which is fixedly connected to the output rod of the throttle piston 46. The throttle piston 46 has a small-diameter hole for hydraulic oil to enter. (Reference) Figure 16 When the air pump 17 is running, outside air will enter the side with the solenoid valve 49.

[0066] There are two solenoid valves 49 connected to the intake pipe 18. When the solenoid valve 49 is opened, compressed air enters one side of the pressure supply piston 47 from the intake pipe 18, causing the output shaft of the pressure supply piston 47 to extend outward and push the pressure supply plate 48. The pressure supply plate 48 is sealed to the hydraulic plate 12. When the pressure supply plate 48 is pushed, it will force the hydraulic oil in front of it into the hole on the throttle piston 46 through one of the hydraulic check valves 45, so that the hydraulic oil enters the throttle piston 46 and causes the output rod of the throttle piston 46 to be pushed out.

[0067] It should be noted that the pressure supply piston 47 needs to be equipped with an air outlet that is opened by pressure. For example, when compressed air enters one side of the pressure supply piston 47, the compressed air on the other side is compressed. When the pressure on that side reaches a certain level, it will open, causing the compressed air to flow out, which in turn causes the output shaft of the pressure supply piston 47 to extend. Similarly, when the output shaft of the pressure supply piston 47 retracts, the compressed air on that side is pressurized, causing the air outlet to open, which in turn causes the compressed air to flow out.

[0068] When motor 14 operates, vibrations are transmitted to throttle piston 46 via mounting plate 44, causing its output rod to move. This compresses the hydraulic oil inside throttle piston 46, causing the hydraulic oil to flow out through a small orifice on throttle piston 46. Because the orifice is small, the hydraulic oil cannot flow out all at once, but only over a period of time, thus creating damping and completing vibration reduction. The outflowing hydraulic oil flows back through another hydraulic check valve 45 to the side near pressure plate 48 to compress the compressed air in pressure piston 47, thereby absorbing vibration and completing vibration reduction.

[0069] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
