Description

Technical Field

[0001] The invention relates to the technical field of tubular oil pumps, in particular to a tubular oil pump with high sealing performance. Background Art

[0002] The working principle of the high-seal tubular oil pump mainly includes two processes: the upstroke and the downstroke. During the upstroke, the sucker rod moves the piston upward, and the floating valve on the piston is closed by the pressure of the liquid column above the piston in the oil pipe. The internal volume of the pump increases, the pressure decreases, and the fixed valve is pushed open under the pressure of the liquid column in the annular space of the oil pipe and casing. The crude oil in the well enters the pump barrel and fills the space vacated by the upward movement of the movable plug. During the downstroke, the sucker rod moves the piston downward, the fixed valve is closed, and the piston squeezes the liquid in the pump to increase the pressure in the pump. When the pressure in the pump exceeds the pressure of the liquid column in the oil pipe, the floating valve is pushed open, and the liquid in the pump is discharged into the oil pipe above the piston.

[0003] When a tubing pump is extracting oil from an oil well, the actual liquid production of the oil stored in the oil well does not always maintain a stable supply. The oil well liquid production is often insufficient. At this time, the tubing pump is always in a constant operating power. The insufficient supply of oil well liquid production will cause the tubing pump to continue to operate at high power in an attempt to extract more liquid. As a result, the internal components of the tubing pump are subjected to unnecessary pressure and friction, which accelerates the wear of the tubing pump and shortens its service life. To this end, we propose a highly sealed tubing pump. Summary of the Invention

[0004] The purpose of the present invention is to provide a high-sealing tubular oil pump to solve the problem proposed in the above background technology that when the tubular oil pump extracts oil from the oil well, the actual liquid production of the oil stored in the oil well does not always maintain a stable supply, and the oil well production is often insufficient. At this time, the tubular oil pump is always at a constant operating power. The insufficient supply of oil well production will cause the tubular oil pump to continue to maintain high-power operation in an attempt to extract more liquid, and then the internal components of the tubular oil pump will be subjected to unnecessary pressure and friction, which will accelerate the wear of the tubular oil pump and shorten its service life.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example 1

[0035] See also Figures 1 to 11 The present invention provides a technical solution: a high-sealing tubular oil pump, comprising: a pump body 1, an oil pumping telescopic tube 6 and an oil pumping pipe 7, wherein the bottom of the pump body 1 is provided with the oil pumping telescopic tube 6, and the bottom of the oil pumping telescopic tube 6 is provided with the oil pumping pipe 7;

[0036] The invention also includes: a detection mechanism 2, which is arranged on the oil extraction pipe 7 and is used to detect the flow speed during oil extraction;

[0037] The gas guide mechanism 3 is provided on the oil extraction pipe 7 and guides the gas to guide a corresponding amount of gas according to the centrifugal force generated by the detection mechanism 2;

[0038] The power regulating mechanism 4 is provided on the pump body 1. The power regulating mechanism 4 adjusts the resistance to a corresponding position according to the amount of gas discharged by the gas guide mechanism 3 and can reversely transport the gas to the gas guide mechanism 3 when necessary to achieve its reset function.

[0039] The extension mechanism 5 is arranged on the pump body 1. The extension mechanism 5 can adjust the oil pumping position according to the reset power-on information sent by the power adjustment mechanism 4.

[0040] By setting the detection mechanism 2 at the upper part of the oil extraction pipe 7, the detection mechanism 2 is located much higher than the oil layer, and no electrical equipment is set in the detection mechanism 2. In this way, it can be ensured that when pumping oil, a layer of oil and gas is prevented from existing on the upper part of the oil layer surface, and the fire phenomenon caused by the operation of the electrical equipment is avoided. The detection mechanism 2 can be used to detect the speed of oil delivery in real time, and then convert the delivery speed into a corresponding centrifugal force, so that the detection work can be completed; by forming a coordination between the air guide mechanism 3 and the power adjustment mechanism 4, the size of the centrifugal force generated by the detection mechanism 2 can be converted into a corresponding gas delivery volume by the air guide mechanism 3, so that the power adjustment mechanism 4 can be used to adjust the resistance value to the corresponding position according to the received gas volume, and then the operating power of the pump body 1 can be adjusted by the power adjustment mechanism 4, such as This can reduce the operation of the pump body 1 in time when the oil well production is insufficient, and then adjust it to the corresponding operating power, thereby preventing the internal components of the tubular oil pump from being subjected to unnecessary pressure and friction, and ultimately reducing the wear of the tubular oil pump and increasing its service life; by setting up the extension mechanism 5, the position of the oil pumping pipe 7 can be adjusted when the power adjustment mechanism 4 is triggered to operate, and the oil pumping pipe 7 can be adjusted to the oil layer position in time, and the stability of the position of the oil pumping pipe 7 can be ensured by the extension mechanism 5, preventing the oil pumping pipe 7 from shaking during the oil pumping operation, which affects the normal and stable transportation of the oil, and then the cooperation between the detection mechanism 2, the air guide mechanism 3 and the power adjustment mechanism 4 can be reused to adjust the pump body 1 to the appropriate operating power, thereby ensuring the smooth progress of the oil pumping operation.

[0041] The detection mechanism 2 includes a protective cover 21 fixedly connected to the outside of the oil extraction pipe 7, and a one-way multi-impeller 22 is rotatably connected to the inside of the protective cover 21;

[0042] When in use, the lower part of the protective cover 21 is designed to be tilted downward to discharge the oil. When the pump body 1 extracts the oil, it drives the unidirectional multi-impeller 22, and the rotation of the unidirectional multi-impeller 22 is used to demonstrate the oil delivery speed.

[0043] One side of the unidirectional multi-impeller 22 is fixedly connected to a first bevel gear 23, one side of the first bevel gear 23 is meshedly connected to a second bevel gear 24, and the outer side of the second bevel gear 24 is rotatably connected to a support block 25;

[0044] When in use, the rotating unidirectional multi-impeller 22 can drive the first bevel gear 23, so that the first bevel gear 23 drives the second bevel gear 24, which is fixedly connected to the inner side of the first fixed box 31 through the support block 25, and the support block 25 can be used to support the second bevel gear 24.

[0045] A centrifugal wheel 26 is fixedly connected to the bottom of the second bevel gear 24. A first chute 27 is defined inside the centrifugal wheel 26. A first spring 29 is fixedly connected to one side of the first chute 27. A first slider 28 is fixedly connected to one side of the first spring 29. A driving rod 211 is fixedly connected to the bottom of the first slider 28. A ball 210 is disposed inside the first chute 27.

[0046] During use, the rotating first bevel gear 23 can drive the centrifugal wheel 26 at the bottom through the second bevel gear 24. When the centrifugal wheel 26 is driven, the sphere 210 will generate centrifugal force. When the oil is delivered faster, the inertia force of the sphere 210 will be greater, so that the sphere 210 pushes the first slider 28 to slide in the first slide groove 27 under the action of centrifugal force. The moving first slider 28 compresses the first spring 29, and when the first slider 28 moves, it can drive the driving rod 211, and the driving rod 211 is used to push the first limit block 34.

[0047] The gas guide mechanism 3 includes a first fixed box 31 fixedly connected to the outside of the oil extraction pipe 7. A first gas cylinder 32 is fixedly connected to the inside of the first fixed box 31. A first piston 33 is provided inside the first gas cylinder 32. A first stopper 34 is fixedly connected to one side of the first piston 33. A gas guide telescopic tube 36 is fixedly connected to the top of the first gas cylinder 32.

[0048] During use, when the first limit block 34 is pushed by the driving rod 211, the pushed first limit block 34 can drive the first piston 33 to move, and the moving first piston 33 pushes the gas in the first gas cylinder 32 into the gas-guiding telescopic tube 36, and the gas amount corresponding to the centrifugal force generated by the detection mechanism 2 is transported through the gas-guiding telescopic tube 36.

[0049] A first one-way valve 35 is fixedly connected to one side of the first air cylinder 32, and a first limiting groove 37 is formed inside the first fixing box 31 to cooperate with the first limiting block 34;

[0050] During use, by setting a first one-way valve 35 on one side of the first gas cylinder 32, the first piston 33 can be used to extract gas at the initial stage, and the first one-way valve 35 can be sealed to prevent excess gas from being drawn in when the first piston 33 is reset. The movable first limit block 34 slides in the first limit groove 37, and the first limit groove 37 provides a guiding and limiting function for the first limit block 34.

[0051] Example 2

[0052] like Figures 3 to 8 In the second embodiment, other structures remain unchanged, and the difference from the first embodiment is:

[0053] The power regulating mechanism 4 includes a second fixed box 41 fixedly connected to the outside of the pump body 1. A second air cylinder 47 is fixedly connected to the inside of the second fixed box 41. A second piston 48 is provided inside the second air cylinder 47. A second one-way valve 49 is provided on one side of the second air cylinder 47. A second solenoid valve 411 is provided on the side of the second one-way valve 49 away from the second air cylinder 47. The bottom of the second solenoid valve 411 is connected to the top of the air guide telescopic tube 36. A first solenoid valve 410 is provided between the second air cylinder 47 and the air guide telescopic tube 36.

[0054] During use, when pumping oil, the first solenoid valve 410 is closed and the second solenoid valve 411 is opened. The gas-transmitting telescopic tube 36 transmits the gas to the second gas cylinder 47 through the second one-way valve 49. When the second gas cylinder 47 is filled with gas, the second piston 48 is pushed to move. When the gas-guiding mechanism 3 needs to be reset, the second solenoid valve 411 is closed and the first solenoid valve 410 is opened, so that the moving second piston 48 can push out the gas in the second gas cylinder 47 and transmit it to the first gas cylinder 32 through the gas-transmitting telescopic tube 36 to reset the first piston 33.

[0055] A sliding rheostat 43 is fixedly connected to the inside of the second fixed box 41. A second limit block 44 is fixedly connected to the top of the sliding piece in the sliding rheostat 43. One side of the second limit block 44 is fixedly connected to one side of the second piston 48. A second limit slot 42 that cooperates with the second limit block 44 is formed inside the second fixed box 41. A first electromagnet 45 is fixedly connected to one side of the second limit block 44. A second electromagnet 46 is fixedly connected to one side of the second fixed box 41.

[0056] During use, when the second gas cylinder 47 is filled with gas to push the second piston 48, the moving second piston 48 drives the second limit block 44, so that the second limit block 44 slides and limits in the second limit slot 42, and the moving second limit block 44 can drive the slider in the sliding rheostat 43, and then adjust to a corresponding appropriate resistance value according to the oil delivery amount. The sliding rheostat 43 is electrically connected to the pump body 1 through a wire, and when the second limit block 44 is close to the second gas cylinder 47, the resistance of the sliding rheostat 43 is the largest, at this time the operating power of the pump body 1 is the smallest, and when the second limit block 44 is away from the second gas cylinder 47, the resistance of the sliding rheostat 43 is the smallest, at this time the operating power of the pump body 1 is the largest. When the oil layer drops, the pump body 1 idles, and the power adjustment is triggered at this time, and the second electromagnet 46 and the first electromagnet 45 are energized. The magnetic poles of the second electromagnet 46 and the first electromagnet 45 facing each other are the same, so that the second electromagnet 46 produces a repulsive force on the first electromagnet 45, thereby pushing the second limit block 44 to move. The moving second limit block 44 can drive the second piston 48 to push the gas in the second air cylinder 47 out, and then the oil delivery speed at this time can be re-detected through the detection mechanism 2 and the air guide mechanism 3, and adjusted to the corresponding resistance value, and the pump body 1 is adjusted to the corresponding operating power to prevent the pump body 1 from idling for a long time, and then the extension mechanism 5 is controlled to adjust the oil pumping position.

[0057] The extension mechanism 5 includes a third fixed box 51 fixedly connected to the outside of the pump body 1. A motor 52 is fixedly connected to one side of the third fixed box 51. A worm 53 is fixedly connected to the output end of the motor 52. The bottom of the worm 53 is meshingly connected to a worm gear 54. A rotating shaft 55 is fixedly connected to the inside of the worm gear 54. The rotating shaft 55 is rotatably connected to the third fixed box 51. A reel 56 is fixedly connected to the outside of the reel 56. A rope 57 is provided on the outside of the reel 56. One end of the rope 57 is fixedly connected to the bottom of the oil extraction telescopic pipe 6.

[0058] During use, when it is necessary to extend the oil extraction pipe 7 downward into the oil, the control motor 52 rotates the worm 53, and the rotating worm 53 drives the worm wheel 54, so that the rotating worm wheel 54 drives the reel 56 through the rotating shaft 55. When the reel 56 rotates, the rope 57 can be released, and the oil extraction telescopic pipe 6 can be extended. The interlocking effect between the worm 53 and the worm wheel 54 can ensure the stability of the position of the reel 56. When it is necessary to recycle the oil extraction pipe 7, the worm wheel 54 is rotated in the opposite direction, so that the worm wheel 54 drives the reel 56 through the rotating shaft 55, and the reel 56 rotating in the opposite direction can recycle the rope 57.

[0059] Two limiting rods 58 are slidably connected to the interior of the third fixed box 51. The bottoms of the two limiting rods 58 are fixedly connected to the bottom end of the oil extraction telescopic pipe 6. A second spring 510 is sleeved on the outer side of the limiting rods 58. A third electromagnet 59 is provided inside the third fixed box 51.

[0060] When in use, the initial state of the second spring 510 is in a compressed state. The second spring 510 is arranged at both ends of the oil extraction telescopic tube 6. The second spring 510 can be compressed by the two ends of the oil extraction telescopic tube 6. When the oil extraction pipe 7 moves downward, the lower end of the oil extraction telescopic tube 6 extends, and the third electromagnet 59 is de-energized, so that the limit rod 58 is driven downward by the second spring 510. When moving, the limit rod 58 slides and guides in the third fixed box 51 to limit. The cooperation between the limit rod 58 and the third fixed box 51 can ensure the stability of the position of the oil extraction pipe 7. When the oil extraction pipe 7 is extended to the desired position, the third electromagnet 59 is energized. The material of the limit rod 58 is iron material. The energized third electromagnet 59 can adsorb the limit rod 58, thereby fixing the position of the limit rod 58 and fixing the position of the bottom oil extraction pipe 7.
