Technical Field

[0001] The invention relates to the technical field of high-lift water pumps, in particular to a high-lift water pump with a self-adaptive flow regulation function. Background Art

[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals.

[0017] Preferably, the trigger mechanism further comprises a conductive plate embedded in the inner wall of the box body, and the conductive sliding plug, the conductive plate and the electromagnet are electrically connected via a wire.

[0018] The present invention has the following beneficial effects:

[0019] 1. By setting the flow regulating mechanism and driving mechanism, the rotation angle of the ball can be adjusted according to the actual water output and water pressure, and then the size of the water outlet can be adjusted, and the water output can be automatically adjusted so that the water output is within the appropriate range. No manual intervention is required, which makes it more convenient to use;

[0020] 2. By setting a head adjustment mechanism, when the water flow rate decreases, the head of the water pump will increase accordingly. Therefore, when the water volume decreases, the movement of the pressure-sensitive block will drive the conductive sliding plug to slide to the left in the box body, and then the air in the box body will enter the air inlet groove through the second connecting pipe, and then the air will enter the sliding groove through the first connecting pipe, pushing the sliding rod to move outward, and then driving multiple arc wheels to move outward, which is equivalent to increasing the diameter of the driven wheel. Then, when the motor speed remains unchanged, the diameter of the driven wheel increases, and its speed will decrease, thereby reducing the speed of the closed impeller, thereby reducing the head of the water pump. On the contrary, if the water output increases, the head of the water pump will decrease. At this time, the diameter of the driven wheel will decrease, thereby increasing the speed of the closed impeller and increasing the head, so that when the water flow rate is adjusted, the head of the water pump is always maintained within a normal range;

[0021] 3. By setting a cleaning mechanism, when there are too many dirt and impurities attached to the closed impeller, the water flow rate will be greatly reduced. If the water flow in the water outlet pipe is reduced to the point where the pressure-sensitive block cannot move, the conductive sliding plug will contact the conductive plate, and the electromagnet will be energized to generate magnetism, generating magnetic repulsion with the magnetic clamping rod, thereby pushing the magnetic clamping rod into the slot. At this time, the rotation of the shaft will drive the rotating ring to rotate through the cooperation of the magnetic clamping rod and the slot, thereby driving the multiple second semicircular heads to rotate. When the second semicircular head moves to the first semicircular head against the first semicircular head, it will push the impact rod to move and impact the closed impeller, causing the closed impeller to vibrate. When the round head is separated from the first semi-circular head, the impact rod will be reset under the action of the third spring, and the impact rod will continuously move back and forth to impact the closed impeller, and the impact rod will synchronously drive the slide plate seal to slide when moving back and forth. Under the action of the slide plate, the descaling agent in the liquid storage tank will be drawn into the pump liquid cavity through the one-way liquid inlet pipe, and then the descaling agent in the pump liquid cavity will enter the water pump housing through the one-way liquid discharge hole, and it will be dispersed in the water and contact with the dirt and impurities in the closed impeller, so as to decompose and remove them, and the impact rod hits the closed impeller to make it vibrate, which is more conducive to the removal of attached dirt and impurities;

[0022] 4. When cleaning the closed impeller, since the water output is at the minimum at this time, the conductive slider is located at the rightmost side of the box body, and the slide rod will completely enter the slide groove at this time, so that the arc wheel is closest to the driven wheel, which is equivalent to the driven wheel having the smallest diameter at this time, and the driven wheel has the fastest speed at this time, so that the closed impeller has the fastest speed at this time, which will generate greater centrifugal force, which is more conducive to throwing out the dirt and impurities attached to the closed impeller.

[0035] The flow regulating mechanism also includes a fixed rod 13 fixedly connected to the side wall of the pressure sensing block 9, and a rack 14 is fixedly connected to the lower end of the fixed rod 13. One end of the valve stem 6 passes through the side wall of the water outlet pipe 3 and is fixedly connected to a gear 15. The rack 14 is meshed with the gear 15.

[0036] A lift regulating mechanism is installed on the rotating shaft 4, and the lift regulating mechanism includes a driven wheel 16 fixedly connected to the side wall of the rotating shaft 4. The side wall of the driven wheel 16 is provided with a plurality of slide grooves 17. The inner walls of the plurality of slide grooves 17 are all sealed and slidably connected with a slide rod 18, and one end of the slide rod 18 is fixedly connected to an arc wheel 19.

[0037] The lift adjustment mechanism also includes an air intake groove 20 opened in the rotating shaft 4, and the air intake groove 20 is connected to the multiple slide grooves 17 respectively through multiple first connecting pipes 21. The side wall of the water pump housing 1 is fixedly connected with a rotating joint 22 through a bracket, one end of the rotating shaft 4 is fixedly connected to the rotating joint 22, and the inner wall of the box body 10 is fixedly connected with a second connecting pipe 23, and the other end of the second connecting pipe 23 is fixedly connected to the rotating joint 22.

[0038] An adjusting mechanism is installed on the water pump housing 1, and the adjusting mechanism includes a groove 24 opened at the upper end of the water pump housing 1, the inner wall of the groove 24 is slidably connected to a vertical plate 25, the side wall of the vertical plate 25 is rotatably connected to a rotating rod 27, the side wall of the rotating rod 27 is fixedly connected to an adjusting wheel 28, the inner wall of the groove 24 is fixedly connected to a guide rod 29, the side wall of the guide rod 29 is slidably connected to the vertical plate 25, and the side wall of the guide rod 29 is sleeved with a second spring 30, and the two ends of the second spring 30 are respectively fixedly connected to the inner wall of the groove 24 and the side wall of the vertical plate 25.

[0039] A driving mechanism is installed on the water pump housing 1, and the driving mechanism includes a motor 31 fixedly connected to the upper end of the water pump housing 1, and a driving wheel 32 is fixedly connected to the output end of the motor 31. The driving wheel 32, the driven wheel 16 and the adjusting wheel 28 are connected by a synchronous belt.

[0040] It should be noted that when the arc wheel 19 moves, the vertical plate 25, under the action of the second spring 30, will make the adjusting wheel 28 always fit closely with the synchronous belt, so as to ensure the transmission force of the synchronous belt.

[0041] Furthermore, by starting the motor 31, the driving wheel 32 is driven to rotate, and then the driven wheel 16 is driven to rotate, the rotating shaft 4 is driven to rotate, and then the closed impeller 5 is driven to rotate, so as to generate suction force, and water is pumped from the water inlet pipe 2 into the water pump housing 1, and then the water is pumped out through the water outlet pipe 3, so as to supply water. When the water is pumped out from the water outlet pipe 3, if the water flow is too large, the water pressure generated will be greater, and then the water pressure will act on the pressure sensing block 9, push the pressure sensing block 9 to move, drive the rack 14 to move, and then drive the gear 15 to rotate, drive the valve stem 6 Rotation, thereby driving the ball 7 to rotate, causing the water outlet 8 to shift, reducing the facing position of the water outlet 8, thereby reducing the water output. When the water output decreases, the water pressure in the water outlet pipe 3 will also decrease, until the water pressure decreases to a level that can no longer overcome the elastic force of the first spring 12. At this time, the pressure-sensitive block 9 will be unable to move, and the ball 7 will stop rotating, so that the water outlet 8 will no longer shift, thereby ensuring the stability of the water output. Therefore, the water output can be automatically adjusted to a suitable range according to the actual water pressure without manual intervention, which is more convenient to use.

[0042] It is worth mentioning that when the water flow rate decreases, the head of the water pump will increase accordingly. Therefore, when the water volume decreases, the movement of the pressure sensing block 9 will drive the conductive sliding plug 11 to slide to the left in the box body 10 (such as Figure 5 As shown), the air in the box body 10 will enter the air inlet groove 20 through the second connecting pipe 23, and then the air will enter the slide groove 17 through the first connecting pipe 21, pushing the slide rod 18 to move outward, thereby driving the multiple arc wheels 19 to move outward, which is equivalent to increasing the diameter of the driven wheel 16. Then, when the speed of the motor 31 remains unchanged, the diameter of the driven wheel 16 increases, and its speed will decrease, thereby reducing the speed of the closed impeller 5, thereby reducing the head of the water pump. On the contrary, if the water output increases, the head of the water pump will decrease. At this time, the diameter of the driven wheel 16 will decrease, thereby increasing the speed of the closed impeller 5 and increasing the head, so that when the water flow is adjusted, the head of the water pump is always maintained within a normal range.

[0043] A cleaning mechanism is installed on the water pump housing 1, and the cleaning mechanism includes a cavity 33 opened in the water pump housing 1. A plurality of impact rods 34 are slidably connected to the inner wall of the water pump housing 1. One end of the plurality of impact rods 34 extends into the cavity 33 and is fixedly connected to a first semicircular head 35. A third spring 36 is sleeved on the side wall of the impact rod 34. The two ends of the third spring 36 are respectively fixedly connected to the inner wall of the cavity 33 and the side wall of the first semicircular head 35. A rotating ring 37 is rotatably connected to the inner wall of the cavity 33, and a plurality of second semicircular heads 38 are fixedly connected to the side wall of the rotating ring 37.

[0044] The cleaning mechanism also includes a pump liquid chamber 39 opened in the water pump housing 1, wherein an impact rod 34 is arranged to penetrate the pump liquid chamber 39, and the side wall of the impact rod 34 located in the pump liquid chamber 39 is fixedly connected with a slide plate 26, and the side wall of the slide plate 26 is sealed and slidably connected to the inner wall of the pump liquid chamber 39, and the upper end of the water pump housing 1 is fixedly connected with a liquid storage tank 40, and the liquid storage tank 40 is filled with a descaling agent. The liquid storage tank 40 is connected with the pump liquid chamber 39 through a one-way liquid inlet pipe 41, and the one-way liquid inlet pipe 41 only allows the descaling agent in the liquid storage tank 40 to enter the pump liquid chamber 39, and the pump liquid chamber 39 is connected with the inside of the water pump housing 1 through a one-way drainage hole 42, and the one-way drainage hole 42 only allows the descaling agent in the pump liquid chamber 39 to enter the water pump housing 1.

[0045] A trigger mechanism is installed on the rotating ring 37, and the trigger mechanism includes two vertical grooves 43 opened on the inner wall of the rotating ring 37. The inner walls of the two vertical grooves 43 are slidably connected with magnetic clamping rods 44. The side wall of the rotating shaft 4 is provided with multiple clamping grooves 45 that cooperate with the magnetic clamping rods 44. The inner wall of the vertical groove 43 is fixedly connected with an electromagnet 46, and a fourth spring 47 is fixedly connected between the inner wall of the vertical groove 43 and the magnetic clamping rod 44.

[0046] The trigger mechanism further includes a conductive plate 48 embedded in the inner wall of the box body 10 , and the conductive slider 11 , the conductive plate 48 and the electromagnet 46 are electrically connected via a wire.

[0047] Furthermore, when there are too many dirt and impurities attached to the closed impeller 5, the water flow rate will be greatly reduced. If the water flow in the water outlet pipe 3 is reduced to the point where the pressure-sensitive block 9 cannot move, the conductive sliding plug 11 will contact the conductive plate 48, and the electromagnet 46 will be energized to generate magnetism, thereby generating a magnetic repulsion force with the magnetic clamping rod 44, thereby pushing the magnetic clamping rod 44 into the clamping groove 45. At this time, the rotation of the rotating shaft 4 will drive the rotating ring 37 to rotate through the cooperation of the magnetic clamping rod 44 and the clamping groove 45, thereby driving the multiple second semicircular heads 38 to rotate. When the second semicircular head 38 moves to abut against the first semicircular head 35, it will push the impact rod 34 to move and impact the closed impeller 5, causing the closed impeller 5 to vibrate. When the first semicircular head 35 is separated from the first semicircular head 35, the impact rod 34 will be reset under the action of the third spring 36, and the impact rod 34 will continue to move back and forth to impact the closed impeller 5, and the impact rod 34 will synchronously drive the slide plate 26 to slide in a sealed manner when moving back and forth. Under the action of the slide plate 26, the descaling agent in the liquid storage tank 40 will be drawn into the pump liquid chamber 39 through the one-way liquid inlet pipe 41, and then the descaling agent in the pump liquid chamber 39 will enter the inside of the water pump housing 1 through the one-way liquid discharge hole 42, and it will be dispersed in the water and contact with the dirt and impurities in the closed impeller 5, so as to decompose and remove them, and the impact rod 34 hits the closed impeller 5 to cause it to vibrate, which is more conducive to the removal of attached dirt and impurities.

[0048] It is worth mentioning that when the closed impeller 5 is cleaned, since the water output is at a minimum at this time, the conductive slide plug 11 is located at the rightmost side of the box body 10, and the slide rod 18 will completely enter the slide groove 17 at this time, so that the arc wheel 19 is at a position closest to the driven wheel 16, which is equivalent to the driven wheel 16 having a minimum diameter at this time, and the driven wheel 16 has a fastest rotation speed at this time, so that the closed impeller 5 has a fastest rotation speed at this time, which will generate a greater centrifugal force, which is more conducive to throwing out the dirt and impurities attached to the closed impeller 5.

[0049] In the present invention, by starting the motor 31, the driving wheel 32 is driven to rotate, and then the driven wheel 16 is driven to rotate, the rotating shaft 4 is driven to rotate, and then the closed impeller 5 is driven to rotate, so as to generate suction force, and water is pumped from the water inlet pipe 2 into the water pump housing 1, and then the water is pumped out through the water outlet pipe 3, so as to supply water. When the water is pumped out from the water outlet pipe 3, if the water flow is too large, the water pressure generated will be greater, and then the water pressure will act on the pressure sensing block 9, push the pressure sensing block 9 to move, drive the rack 14 to move, and then drive the gear 15 to rotate, drive the valve stem 6 Rotation, thereby driving the ball 7 to rotate, causing the water outlet 8 to shift, reducing the facing position of the water outlet 8, thereby reducing the water output. When the water output decreases, the water pressure in the water outlet pipe 3 will also decrease, until the water pressure decreases to a level that can no longer overcome the elastic force of the first spring 12. At this time, the pressure-sensitive block 9 will be unable to move, and the ball 7 will stop rotating, so that the water outlet 8 will no longer shift, thereby ensuring the stability of the water output. Therefore, the water output can be automatically adjusted to a suitable range according to the actual water pressure without manual intervention, which is more convenient to use.

[0050] When the water flow rate decreases, the lift of the water pump will increase accordingly. Therefore, when the water volume decreases, the pressure sensing block 9 moves to drive the conductive sliding plug 11 to slide to the left in the box body 10 (such as Figure 3 As shown), the air in the box body 10 will enter the air inlet groove 20 through the second connecting pipe 23, and then the air will enter the slide groove 17 through the first connecting pipe 21, pushing the slide rod 18 to move outward, thereby driving the multiple arc wheels 19 to move outward, which is equivalent to increasing the diameter of the driven wheel 16. Then, when the speed of the motor 31 remains unchanged, the diameter of the driven wheel 16 increases, and its speed will decrease, thereby reducing the speed of the closed impeller 5, thereby reducing the head of the water pump. On the contrary, if the water output increases, the head of the water pump will decrease. At this time, the diameter of the driven wheel 16 will decrease, thereby increasing the speed of the closed impeller 5 and increasing the head, so that when the water flow is adjusted, the head of the water pump is always maintained within a normal range.

[0051] In addition, when there are too many dirt and impurities attached to the closed impeller 5, the water flow rate will be greatly reduced. If the water flow in the water outlet pipe 3 is reduced to the point where the pressure-sensitive block 9 cannot move, the conductive sliding plug 11 will contact the conductive plate 48, and the electromagnet 46 will be energized to generate magnetism, thereby generating a magnetic repulsion force with the magnetic clamping rod 44, thereby pushing the magnetic clamping rod 44 into the clamping groove 45. At this time, the rotation of the rotating shaft 4 will drive the rotating ring 37 to rotate through the cooperation of the magnetic clamping rod 44 and the clamping groove 45, thereby driving the multiple second semicircular heads 38 to rotate. When the second semicircular heads 38 move to abut against the first semicircular heads 35, they will push the impact rod 34 to move and impact the closed impeller 5, causing the closed impeller 5 to vibrate. When separated from the first semicircular head 35, the impact rod 34 will be reset under the action of the third spring 36, and the impact rod 34 will continue to move back and forth to impact the closed impeller 5, and the impact rod 34 will synchronously drive the slide plate 26 to slide in a sealed manner during the reciprocating movement. Under the action of the slide plate 26, the descaling agent in the liquid storage tank 40 will be drawn into the pump liquid chamber 39 through the one-way liquid inlet pipe 41, and then the descaling agent in the pump liquid chamber 39 will enter the inside of the water pump housing 1 through the one-way liquid discharge hole 42, and it will be dispersed in the water and contact with the dirt and impurities in the closed impeller 5, thereby decomposing and removing them, and the impact rod 34 hits the closed impeller 5 to cause it to vibrate, which is more conducive to the shedding of attached dirt and impurities.

[0052] When cleaning the closed impeller 5, since the water output is at a minimum at this time, the conductive slide plug 11 is located at the rightmost side of the box body 10, and the slide rod 18 will completely enter the slide groove 17 at this time, so that the arc wheel 19 is at a position closest to the driven wheel 16, which is equivalent to the driven wheel 16 having a minimum diameter at this time, and the driven wheel 16 has a fastest rotation speed at this time, so that the closed impeller 5 has a fastest rotation speed at this time, which will generate a greater centrifugal force, which is more conducive to throwing out the dirt and impurities attached to the closed impeller 5.

[0053] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
