Description

Technical Field

[0001] The invention relates to the technical field of oil pipeline cleaning, in particular to a pipeline cleaning device based on an intelligent automatic ball throwing and receiving mechanism for the pipeline. Background Art

[0002] When fluid is transported through a pipeline, the fluid often contains a certain amount of impurities. After the pipeline has been used for a period of time, these impurities will be deposited in the pipeline, which will affect the pipeline's transportation of the fluid. Therefore, wax cleaning balls will be placed at the inlet of the oil pipeline and recovered at the end of the oil and gas pipeline to clean the inner wall of the pipeline.

[0003] The inner wall of the pipeline is basically cleaned with a ball collecting barrel, which relies on manual reversal of the gate, opening of the barrel cover, and taking out the wax cleaning balls, which is time-consuming and laborious. The automatic ball collecting products in the existing technology are complicated to operate, the equipment is bulky, and the installation requires the cooperation of lifting equipment. Sometimes the balls cannot be collected or are stuck. The crude oil that comes out with the wax cleaning balls cannot be automatically recovered and can only be recovered manually. It has poor safety, high maintenance costs, low efficiency, and other problems, and cannot meet the development needs of the oil, natural gas and other industries.

[0004] In actual operation, due to factors such as pipeline pressure and fluid state, the wax cleaning ball may still get stuck in certain parts of the pipeline, especially at the three-way ball valve, affecting the smoothness of the entire cleaning process and reducing the cleaning efficiency.

[0005] To address this problem, a patent application with publication number CN117816676A discloses an intelligent ball-casting and collecting pipe cleaning device, which includes an outer shell, a ball storage barrel, a ball collecting box and a liquid pump, and a ball storage barrel is installed below the outer shell, a ball collecting box is installed below the ball storage barrel, and a liquid pump is provided on the right side of the ball collecting box. A spiral groove is opened on the inner side of the outer shell, and a flow control component is installed on one side of the spiral groove. The flow control component changes the position of the flip ball through the flow of liquid, thereby changing the flow direction of the liquid. A ball collecting component is installed below the flow control component, and a connecting rod in the ball collecting component rotates periodically under the drive of the flip ball in the flow control component, so that the cleaning ball falls into the ball collecting box, thereby solving the problems of wax and scaling blockage in crude oil gathering and transportation pipelines and cleaning of water accumulation in natural gas gathering and transportation pipelines, ensuring the smooth flow of oil and gas transmission pipelines, and improving the overall operation efficiency of the pipeline network.

[0006] However, although the above technical solution is equipped with liquid flow and flipping balls to achieve anti-blockage, it has little effect on the wax cleaning balls and dirt blockages at the corners, and cannot quickly clear the blockage, thereby reducing work efficiency. At the same time, when the electric actuator controls the piston to fall, the pressure is often too high due to the blockage, which makes it difficult for the piston to fall and cannot be closed, resulting in damage to the equipment and the wax cleaning balls cannot be recovered. Although adding an exhaust port has an auxiliary effect, manual cooperation is still required to clear the blocked area, and the automation of the clearing process cannot be achieved. Summary of the invention

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0040] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0041] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0042] Example 1

[0043] Reference Figure 1~Figure 5 , which is the first embodiment of the present invention, provides a pipeline cleaning device based on an intelligent automatic ball throwing and collecting mechanism for pipelines, including a wax cleaning ball 100 and a flow channel switching assembly, a separation assembly and a clearing assembly, so that the recovery process of the wax cleaning ball 100 is fully automated, reducing dependence on manual operation, reducing labor intensity and safety risks in operation, and is particularly suitable for complex environments such as high pressure and high temperature.

[0044] Specifically, it includes: a wax cleaning ball 100, which is used to clean the inner wall of the oil flow channel;

[0045] The flow channel switching assembly includes a first flow channel 200 and a second flow channel 201. A first piston 202 and a second piston 203 are slidably disposed in the first flow channel 200 and the second flow channel 201, respectively. The first piston 202 is used to control the flow direction of the wax cleaning ball 100 and the crude oil in the first flow channel 200.

[0046] The separation assembly includes a ball collecting cylinder 300 and a separation box 301 disposed below the ball collecting cylinder 300, and the separation box 301 is used to separate the wax cleaning balls 100 and the crude oil;

[0047] The blockage clearing assembly includes an eccentric disk 400 and spiral strips 401 arranged on the eccentric disk 400. When the wax clearing balls 100 and crude oil in the first flow channel 200 and the second flow channel 201 are blocked, the eccentric disk 400 rotates eccentrically to generate vibration and the spiral strips 401 rotate and stir.

[0048] Among them, in this embodiment, the first flow channel 200 and the second flow channel 201 are parallel oil pipelines, one end of the first flow channel 200 is attached to and connected with the outer wall of the second flow channel 201 through a right-angle connecting pipe, and the second piston 203 is sealed and attached to the inner wall of the second flow channel 201.

[0049] Preferably, in this embodiment, the upper end surfaces of the first piston 202 and the second piston 203 are respectively provided with a first control member 2001 and a second control member 2002, and the first control member 2001 and the second control member 2002 control the switching of the first piston 202 and the second piston 203 during rotation.

[0050] More preferably, one end of the first control component 2001 and the second control component 2002 respectively penetrate to the outside of the first flow channel 200 and the second flow channel 201 and are provided with an electric actuator 2003, the outer wall of the first flow channel 200 is also connected to a three-way pipe 2004, the inner wall of the three-way pipe 2004 is provided with a guide pattern 2025, and the outer wall of the first flow channel 200 is also provided with an exhaust port 2008.

[0051] Among them, the three-way pipe 2004 and the axis of the first flow channel 200 are in the same plane, and the two are arranged vertically. The first control component 2001 and the second control component 2002 are cylindrical connecting columns. The first control component 2001 vertically penetrates the three-way pipe 2004, so that at this time the wax cleaning ball 100 is blocked by the first control component 2001 and flows downward along the first flow channel 200.

[0052] More preferably, when the wax cleaning ball 100 and part of the crude oil flow to the first flow channel 200 in the three-way pipe 2004, they are blocked by the first control member 2001 and fall into the first flow channel 200. When the first control member 2001 rotates, it drives the first piston 202 to open, and the wax cleaning ball 100 falls into the second flow channel 201 along the first flow channel 200.

[0053] Among them, the ball collecting cylinder 300 is the space above the second piston 203 in the second flow channel 201. The wax cleaning balls 100 and crude oil are stored in the ball collecting cylinder 300 after entering the second flow channel 201. When the exhaust port 2008 is opened, the internal and external air pressures are balanced, so that the wax cleaning balls 100 and crude oil fall faster.

[0054] Furthermore, a separation net 2005 is provided in the separation box 301 , a reflux pipe 2006 is provided below the separation box 301 , the other end of the reflux pipe 2006 is connected to the ball collecting cylinder 300 , and a reflux pump 2007 is also provided on the reflux pipe 2006 .

[0055] The aperture size of the separation net 2005 allows the crude oil to fall down while the wax cleaning balls 100 are filtered and blocked above. The reflux pipe 2006 is connected to the separation box 301 in the area below the separation net 2005, so as to extract the filtered crude oil.

[0056] In summary, when in use, after the wax cleaning ball 100 completes the cleaning work on the inner wall of the oil pipeline, it flows along the three-way pipe 2004 to the first flow channel 200, and is blocked by the first control component 2001 and falls downward into the first flow channel 200. At this time, the electric actuator 2003 controls the first control component 2001 to rotate and control the first piston 202 to open, and the wax cleaning ball 100 continues to fall. At this time, the exhaust port 2008 is opened, the internal and external air pressures are balanced, and the falling speed is accelerated, so that it falls into the ball collecting tube 300 in the second flow channel 201 for storage.

[0057] At the same time, the first control member 2001 rotates in the opposite direction to control the first piston 202 to close, and the second control member 2002 rotates to open the second piston 203, and the wax cleaning balls 100 fall into the separation box 301, and the wax cleaning balls 100 and crude oil are diverted through the separation net 2005, and the filtered crude oil is transported back to the ball collecting barrel 300 through the reflux pipe 2006 and the reflux pump 2007 or recycled through the branch pipe on the reflux pipe 2006. In the absence of electricity, the operation can also be performed through the wheel on the electric actuator 2003, and the entire operation process is controlled by the PLC for cyclic operation, which saves labor costs and improves ball collection efficiency.

[0058] Example 2

[0059] Reference Figure 1 , Figure 6~Figure 10 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that a pressure relief cover 3001 is movably provided on the first piston 202 to guide part of the crude oil to flow back when the area below the first flow channel 200 is blocked, thereby reducing the internal pressure and preventing the electric actuator 2003 from being unable to work due to excessive resistance.

[0060] Specifically, a pressure relief cover 3001 is slidably provided inside the first piston 202 , a transmission rod 3002 is provided inside the pressure relief cover 3001 , and the transmission rod 3002 movably passes through the first control member 2001 . A receiving groove 3003 is also provided inside the first piston 202 , and the pressure relief cover 3001 is slidably provided inside the receiving groove 3003 .

[0061] Among them, a first elastic member 3004 is provided between the end face of the pressure relief cover 3001 and the receiving groove 3003, an annular groove 3005 is opened on the inner wall of the receiving groove 3003, a leakage hole 3006 is provided on the end face of the annular groove 3005, and the leakage hole 3006 runs through the first piston 202, and a corrugated groove 3007 is provided on the lower end face of the pressure relief cover 3001.

[0062] In this embodiment, the first piston 202 is a shuttle-shaped cylinder and slides against the inner wall of the first flow channel 200 . The pressure relief cover 3001 is coaxially arranged with the first piston 202 and can slide and rotate in the first piston 202 .

[0063] Among them, in this embodiment, the first control component 2001 controls the lifting and lowering of the first piston 202. When the first piston 202 moves to above the three-way pipe 2004, the wax cleaning ball 100 and the crude oil flow downward into the first flow channel 200. When the internal pressure increases due to slow flow or blockage, the ball collection speed is slow. When the electric actuator 2003 is used to push the first piston 202 downward, the electric actuator in the prior art has too much resistance and generates shaking and heating, which affects normal use and poses a safety hazard.

[0064] In the present invention, the first elastic member 3004 is slidably sleeved on the outside of the transmission rod 3002, and the leakage holes 3006 are arranged in a circular array on the first piston 202. In the initial state of the pressure relief cover 3001, under the push of the first elastic member 3004, the corrugated groove 3007 is not connected with the annular groove 3005, and the upper part of the pressure relief cover 3001 blocks the annular groove 3005, and the first piston 202 is sealed as a whole, and crude oil is not allowed to pass through.

[0065] More preferably, a circumferential array of corrugated grooves 3007 is provided on the pressure relief cover 3001 . When the corrugated grooves 3007 are connected to the annular grooves 3005 , the first piston 202 is connected up and down to allow the crude oil to pass through while continuing to block the wax cleaning balls 100 .

[0066] In summary, when in use, the first piston 202 moves upward, and the wax cleaning balls 100 and crude oil flow downward into the first flow channel 200. When the wax cleaning balls 100 and crude oil in the area below the first flow channel 200 flow slowly, the pressure below the first piston 202 in the first flow channel 200 increases. At this time, the first control member 2001 drives the first piston 202 to move downward. Due to the excessive pressure below, the pressure relief cover 3001 is pushed to slide inward along the receiving groove 3003, so that the seal of the pressure relief cover 3001 on the annular groove 3005 disappears, and when the corrugated groove 3007 moves to the annular groove 3005 area, it is connected with it.

[0067] At the same time, due to the excessive pressure, the crude oil flows along the corrugated groove 3007 to the annular groove 3005, and flows back to the first flow channel 200 from each leakage hole 3006 to achieve pressure reduction. At the same time, the spiral strips 401 stir each wax cleaning ball 100 so that it falls smoothly into the ball collecting barrel 300, preventing the heating problem caused by blockage and improving the ball collecting efficiency.

[0068] Example 3

[0069] Reference Figure 1-Figure 10 , which is the third embodiment of the present invention, is based on the previous embodiment, except that, while the pressure relief cover 3001 is lifted up, the eccentric disk 400 rotates eccentrically to generate high-frequency and low-amplitude vibrations, which cooperate with the spiral strips 401 to stir and disturb, thereby further clearing the clogged wax cleaning balls 100.

[0070] Specifically, a slide groove 4001 is formed on the upper end surface of the first control member 2001 , a slide bar 4002 is formed on one end of the transmission rod 3002 located in the slide groove 4001 , and a rotation groove 4003 is formed on the slide groove 4001 .

[0071] Among them, the slide groove 4001 and the rotating groove 4003 are vertically arranged, the slide bar 4002 is slidably arranged in the slide groove 4001, and the slide bar 4002 rotates freely after sliding into the rotating groove 4003. The electric actuator 2003 in this embodiment is a servo motor and is directly connected to the transmission rod 3002.

[0072] The first flow channel 200 has a rotating sleeve 4004 disposed on its inner wall. A spiral groove 4005 is formed on its inner wall. The first control member 2001 slides through the spiral groove 4005 and has sliding posts 4006 disposed in a linear array.

[0073] More preferably, the first control member 2001 is divided into two parts, a rotating joint 4007 is provided between the two parts, a cylinder 4008 is provided on the outer wall of the pressure relief cover 3001, a square frame 4009 is provided on the end face of the cylinder 4008, and a slide rod 4011 is slidably provided in the square frame 4009.

[0074] Furthermore, the slide post 4006 is slidably disposed in the spiral groove 4005 . When the electric actuator 2003 drives the first control member 2001 to rotate via the slide bar 4002 on the transmission rod 3002 , the first control member 2001 is lifted and lowered by sliding between each slide post 4006 and the spiral groove 4005 .

[0075] Preferably, one end face of the slide rod 4011 is provided with a second elastic member 4012, and the other end face slides through and extends to the outside of the frame 4009 and is provided with a ball 4013. The end face of the first piston 202 is also provided with a bowl-shaped groove 4014, and the ball 4013 is rotatably fitted on the inner wall of the bowl-shaped groove 4014.

[0076] More preferably, an eccentric disk 400 is provided on the end surface of the sliding rod 4011 , a buffer rod 4016 is slidably provided on the eccentric disk 400 , and a third elastic member 4017 is provided on the buffer rod 4016 and the inner wall of the eccentric disk 400 .

[0077] Among them, a buffer block 4018 is further provided at one end of the buffer rod 4016 extending outside the eccentric disk 400 , and the spiral strip 401 is fixed on the lower end surface of the eccentric disk 400 .

[0078] Among them, the other end face of the second elastic member 4012 is connected to the inner wall of the square frame 4009, the sliding rod 4011 slides on the square frame 4009 and rotates with the pressure relief cover 3001 without falling off, the buffer block 4018 is in a circular ring shape, and is arranged on the outer wall of the eccentric disk 400 in a circular array with the buffer rod 4016.

[0079] Preferably, the spiral strip 401 is made of rubber and while rotating and sliding against the inner wall of the first flow channel 200, it also removes petroleum impurities attached to the inner wall to prevent blockage. The third elastic member 4017 is a spring, which is used to push the buffer block 4018 to extend outward. The outer wall of the buffer block 4018 is wear-resistant rubber, which generates high-frequency and small-amplitude vibrations when an elastic collision occurs with the inner wall of the first flow channel 200, thereby unblocking the blocked wax cleaning ball 100 together with the stirring of the spiral strip 401.

[0080] In summary, during use, when the first piston 202 needs to fall for a new round of ball collecting operation, the electric actuator 2003 starts and controls the transmission rod 3002 to rotate, and at the same time, the slide bar 4002 located in the slide groove 4001 drives the first control component 2001 to rotate, and the slide column 4006 on the outer wall of the first control component 2001 rotates along the spiral groove 4005, so that the upper part of the first control component 2001 rotates and descends, and drives the lower part to move downward through the rotating joint 4007, and the first piston 202 slides and descends along the first flow channel 200.

[0081] At the same time, when the area below the first flow channel 200 is blocked by the wax cleaning balls 100 and the crude oil and impurities removed from the inner wall of the pipeline, resulting in slow material discharge, the pressure in the area below the first flow channel 200 increases, and at the same time, the pressure relief cover 3001 is pushed to slide upward to filter and drain the crude oil to reduce the pressure. At the same time, the transmission rod 3002 connected to the pressure relief cover 3001 slides upward until the slide bar 4002 slides from the slide groove 4001 to the rotating groove 4003 and rotates freely. At this time, the first control member 2001 is no longer driven to rotate and descend, but stops in place and is stirred and cleared by the spiral bar 401, thereby realizing the function of automatic pressure relief and dredging under high pressure in the pipeline area.

[0082] And as the pressure relief cover 3001 slides upward, the frame 4009 and the ball 4013 slide upward synchronously with the first piston 202. Since the diameter of the bowl-shaped groove 4014 is larger at the bottom and smaller at the top, the ball 4013 rolls with the inner wall of the bowl-shaped groove 4014 when the frame 4009 rises, and pushes the slide bar 4011 to overcome the thrust of the second elastic member 4012 and leave the equilibrium position, so that the center of the eccentric disk 400 connected to the slide bar 4011 deviates from the center position of the frame 4009. When the pressure relief cover 3001 drives the frame 4009 to rotate, it also drives the eccentric disk 400 to rotate eccentrically. At the same time, each buffer block 4018 continuously contacts the inner wall of the first flow channel 200 for collision, and then resets under the push of the third elastic member 4017. The reciprocating cycle causes high-frequency and low-amplitude vibrations to be generated on the inner wall of the first flow channel 200, and the spiral strip 401 is used for stirring and disturbance, so as to further clear the blocked wax cleaning ball 100.

[0083] When the blocked area is unblocked, the internal pressure is balanced and reduced through the exhaust port 2008, so that the pressure relief cover 3001 moves downward and resets, the first piston 202 is re-sealed, and the first control member 2001 continues to move downward, thereby realizing automatic clearing and automatic resetting after clearing. The entire process does not require manual operation, which improves work efficiency and reduces the downtime and maintenance time caused by clearing.
