Abstract
Description
Technical Field
[0001] This application relates to the technical field of pipeline cleaning, and in particular to a flow aid device for reducing transport residue in pipeline transportation. Background Technology
[0002] Pipeline transportation is a long-distance transport method that uses pipelines to transport liquids. It is a specialized mode of transporting petroleum and chemical products from production sites to markets and is a unique component of trunk line transportation within a unified transportation network. Over time, pipelines accumulate significant scale buildup, which reduces the pipeline's inner diameter and impacts its transport efficiency.
[0003] A search revealed Chinese Patent Publication No. CN109647809A, which discloses an oilfield pipeline cleaning device. The device includes a cutter bar with a cutter head connected to one end and a first telescopic rod connected to the other end. Multiple coarse scraping teeth are evenly distributed on the outer wall of the cutter head. A guide drill bit with a conical cross-section is fixedly mounted on the end face of the cutter head. The guide drill bit has an inclined cutting edge. A brush body device is provided on the surface of the cutter bar, comprising a brush plate, a second telescopic rod, and a brush. The brush plate is parallel to the cutter bar and connected to it via the second telescopic rod. The surface of the brush plate has a T-shaped platform, and the surface of the brush has an L-shaped groove corresponding to the T-shaped platform, which engages with the T-shaped platform. A power device is connected to the first telescopic rod, and a suction pipe is provided outside the power device, with a suction device installed on the suction pipe. The oilfield pipeline cleaning device provided by this invention has a simple structure, thoroughly removes scale, and leaves no residue.
[0004] Regarding the aforementioned technologies, the inventors discovered the following drawbacks: the size of the guide drill bit and the coarse scraper teeth is constant, making them unsuitable for cleaning stubborn dirt adhering to the inner wall of pipes; and the brush plate with bristles alone is insufficient for effective cleaning. Furthermore, for longer pipes, if the cleaning device is moved by a traction rope, the soft bristles against the inner wall of the pipe cannot effectively limit the direction of movement, causing the brush plate to not rotate accurately around the pipe axis. This accelerates brush wear and affects the descaling effect on the pipe. Therefore, improvements are needed. Summary of the Invention

[0012] Optionally, a collection unit is provided below the mounting rod, located between the scraper unit and the limiting unit.

The fourth elastic telescopic component is connected to the inside of the mounting shell through a fourth flexible hose. One end of the collection box is open and faces the scraper unit, and the other end of the collection box is provided with a guide pipe that can extend out of the pipeline.
[0013] Optionally, the mounting rod is hollow inside, connected to a water inlet pipe, and has spray holes on its side wall that connect to the inside of the mounting rod and face the scraper unit.
[0014] Optionally, it also includes a bracket, with the mounting rod slidingly connected to the bracket along its own axis. The bracket is provided with several clamping units arranged circumferentially around the axis of the mounting rod and several clamping units arranged circumferentially around the axis of the mounting rod.

[0022] 4. When the flow aid device moves steadily forward in the pipeline, external water can enter the mounting rod through the inlet pipe and be sprayed onto the scraper body, brush body and inner wall of the pipeline through the spray hole.

[0032] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.
[0033] This application discloses a flow-aiding device for reducing transport residue in pipeline transportation. For example... Figure 1 and Figure 2 As shown, a flow aid device for reducing transport residue in pipeline transportation includes an installation rod 2 and a sleeve 3 arranged coaxially. The installation rod 2 is provided with a power supply unit 4 and a plurality of limiting units 5 arranged circumferentially around the axis of the installation rod 2. The power supply unit 4 includes an installation shell 41 installed on the installation rod 2, and a slider 42 is slidably embedded in the installation shell 41.
[0034] In this embodiment, there are three sets of limiting units 5. Each limiting unit 5 includes a first elastic telescopic component 51 filled with fluid. The fixed end of the first elastic telescopic component 51 is mounted on the mounting rod 2. The telescopic end of the first elastic telescopic component 51 is mounted with a limiting plate 52. The end of the limiting plate 52 facing the sleeve 3 is folded towards the axis of the mounting rod 2 and is inclined. The first elastic telescopic component 51 is connected to the inside of the mounting shell 41 through a first flexible hose 53.
[0035] As the external traction rope pulls the installation rod 2 deeper into the pipe 12, the folded end of the limiting plate 52 will abut against the inner wall of the end of the pipe 12 and gradually move closer to the axis of the installation rod 2. The fluid in the first elastic telescopic component 51 will flow into the mounting shell 41 through the first hose 53, causing the slider 42 to slide in the mounting shell 41. The first elastic telescopic component 51 will cause the limiting plate 52 to press against the inner wall of the pipe 12 due to its own rebound force, so that this application can automatically adapt to pipes 12 of different sizes. The mutual abutment of multiple limiting plates 52 against the inner wall of the pipe 12 makes it difficult for the flow aid device to shake in the pipe 12, ensuring the stability of the flow aid device during movement.
[0036] like Figure 2 and Figure 3 As shown, the mounting shell 41 is arranged in a ring and fixedly sleeved on the mounting rod 2, and the slider 42 is arranged in a ring and slidably sleeved on the mounting rod 2. The fluid can be water, gel or other relatively stable solutions. Multiple limiting units 5 are also provided along the axial direction of the mounting rod 2 to improve the stability of the limiting plate 52 when it abuts against the inner wall of the pipe 12.
[0037] The limiting plate 52 is provided with several hemispherical grooves 54 on the side away from the axis of the mounting rod 2. An elastic ball 55 is rolled and embedded in the hemispherical groove 54. The elastic ball 55 protrudes out of the hemispherical groove 54 and can abut against the inner wall of the pipe 12, thereby replacing the sliding contact between the limiting plate 52 and the inner wall of the pipe 12 with the rolling contact between the elastic ball 55 and the inner wall of the pipe 12, reducing the friction force experienced by the flow aid device during movement.
[0038] The diameter of the elastic ball 55 is larger than the diameter of the opening of the hemispherical groove 54, making it difficult for the elastic ball 55 to fall out of the hemispherical groove 54. However, due to its own elasticity, the elastic ball 55 can be removed from the hemispherical groove 54 or pressed into the hemispherical groove 54 by workers with the help of tools, so as to facilitate the disassembly and assembly of the elastic ball 55.
[0039] The first elastic telescopic component 51 is an elastic telescopic rod filled with fluid, which not only limits the movement direction of the limiting plate 52, but also ensures that the limiting plate 52 can automatically move and reset after it is separated from the pipe 12.
[0040] like Figure 5 and Figure 6As shown, two spaced bearings 21 are fixedly sleeved on the mounting rod 2, and the sleeve 3 is fixedly sleeved on the two bearings 21, so that the sleeve 3 is rotatably connected to the mounting rod 2 around its own axis; the mounting rod 2 is provided with a drive unit 6, which includes a motor 61 mounted on the side wall of the mounting rod 2, a gear 62 is fixedly sleeved on the output shaft of the motor 61, and an internal gear ring 63 is fixedly embedded in the sleeve 3. The gear 62 meshes with the internal gear ring 63, and the motor 61 can drive the sleeve 3 to rotate through the meshing of the gear 62 and the internal gear ring 63; the motor 61 is located inside the sleeve 3, thereby minimizing contact between the motor 61 and the dirt inside the pipe 12.
[0041] The sleeve 3 is provided with a plurality of scraper units 7 and a plurality of brush units 8 arranged circumferentially around the axis of the sleeve 3. The brush units 8 are located between the scraper units 7 and the limiting unit 5. In this embodiment, the number of scraper units 7 and brush units 8 is three sets.
[0042] The scraper unit 7 includes a second elastic telescopic component 71 filled with fluid. The second elastic telescopic component 71 has the same structure as the first elastic telescopic component 51. The fixed end of the second elastic telescopic component 71 is installed on the outer wall of the sleeve 3, and the telescopic end of the second elastic telescopic component 71 is equipped with a scraper body 72. The brush unit 8 includes a third elastic telescopic component 81 filled with fluid. The third elastic telescopic component 81 has the same structure as the first elastic telescopic component 51. The fixed end of the third elastic telescopic component 81 is installed on the outer wall of the sleeve 3, and the telescopic end of the third elastic telescopic component 81 is equipped with a brush body 82.
[0043] like Figure 7 and Figure 8 As shown, a first storage bladder 22, which is annular and filled with fluid, is fixedly sleeved on the mounting rod 2. The first storage bladder 22 is located inside the sleeve 3, thereby minimizing contact between the first storage bladder 22 and the dirt inside the pipe 12. The first storage bladder 22 is connected to the second elastic telescopic component 71 through the second flexible hose 23, and the third elastic telescopic component 81 is connected to the second flexible hose 23 through the third flexible hose 24. A one-way valve 25 is installed on the second flexible hose 23.
[0044] When the motor 61 drives the sleeve 3 to rotate via the gear 62 and the internal gear ring 63, the sleeve 3 will drive the scraper body 72 to rotate via the second elastic telescopic component 71. The second elastic telescopic component 71 will extend due to the centrifugal force of the scraper body 72, and the scraper body 72 will move away from the axis of the mounting rod 2. The first storage bladder 22 will deform, and the fluid in the first storage bladder 22 will enter the second elastic telescopic component 71 through the second hose 23. This allows the second elastic telescopic component 71 to stably support the scraper body 72 against the inner wall of the pipe 12 of different sizes. The scraper body 72 will rotate and scrape off the dirt attached to the inner wall of the pipe 12, reducing the amount of material residue inside the pipe 12 and preventing the inner diameter of the pipe 12 from becoming smaller due to dirt accumulation, thereby achieving the effect of assisting flow.
[0045] The sleeve 3 will also drive the brush body 82 to rotate through the third elastic telescopic component 81. Due to the centrifugal force of the brush body 82, the third elastic telescopic component 81 will extend, and the brush body 82 will move away from the axis of the mounting rod 2. The first storage bladder 22 will deform, and the fluid in the first storage bladder 22 will enter the third elastic telescopic component 81 through the second hose 23 and the third hose 24. This allows the third elastic telescopic component 81 to stably support the brush body 82 against the inner wall of the pipe 12 of different sizes. The brush body 82 will rotate and brush away the dirt attached to the inner wall of the pipe 12, further reducing the amount of material residue inside the pipe 12, so as to achieve a better flow assist effect.
[0046] It is worth noting that the one-way valve 25 allows fluid to flow only from the first storage bladder 22 into the second elastic telescopic component 71 and the third elastic telescopic component 81, while the fluid in the second elastic telescopic component 71 and the third elastic telescopic component 81 cannot flow back into the first storage bladder 22 through the one-way valve 25. This ensures that the scraper body 72 and the brush body 82 remain stable during use.
[0047] The second flexible tube 23 has a connecting tube 26 on its side, with both ends of the connecting tube 26 connected to the second flexible tube 23. A one-way valve 25 is located between the two ends of the connecting tube 26, and a solenoid valve 261 is installed on the connecting tube 26. When the flow aid device is not in use, the worker can open the solenoid valve 261. At this time, the second elastic telescopic component 71 and the third elastic telescopic component 81 can return to their natural state, and the fluid inside them will flow back into the first storage bladder 22 through the solenoid valve 261 for subsequent use of the flow aid device.
[0048] The scraper body 72 is folded at the end away from the brush body 82 and is inclined toward the axis of the sleeve 3. A scraper 73 is installed at the folded end of the scraper body 72. During the movement of the flow aid device, the scraper 73 will first rotate and scrape off the dirt adhering to the inner wall of the pipe 12, so that the scraper body 72 can rotate and clean the dirt on the inner wall of the pipe 12 in the subsequent process.
[0049] like Figure 3 and Figure 8 As shown, the power supply unit 4 includes a power supply 43 and a power supply block 44 mounted on the side wall of the mounting rod 2. The power supply 43 is connected to the power supply block 44 through a wire. One end of the slider 42 extends out of the mounting shell 41 and is equipped with a conductive block 45. The conductive block 45 is connected to the motor 61 through a wire.
[0050] When the limiting plate 52 moves closer to the axis of the mounting rod 2, causing the slider 42 to gradually extend outside the mounting shell 41, the slider 42 will drive the conductive block 45 to move and abut against the power supply block 44. At this time, the power supply 43 will supply power to the motor 61 through the power supply block 44 and the conductive block 45. The motor 61 will drive the scraper body 72 and the brush body 82 to rotate through the sleeve 3. That is, when the limiting plate 52 automatically abuts against the inner wall of the pipe 12 of different sizes, the scraper body 72 will automatically rotate to scrape off the dirt attached to the inner wall of the pipe 12, and the brush body 82 will automatically rotate to brush off the dirt attached to the inner wall of the pipe 12.
[0051] It is worth noting that if the compression of the first elastic telescopic component 51 is large, the amount of fluid flowing out of the first elastic telescopic component 51 will be large. When the conductive block 45 presses against the power supply block 44, the fluid continuing to flow into the mounting housing 41 will cause the first hose 53 to expand. The expanded first hose 53 is used to accommodate the excess fluid in order to avoid damage to the power supply block 44 and the conductive block 45 due to excessive pressing.
[0052] The power supply 43, power supply block 44, and conductive block 45 are all located inside the sleeve 3, thereby minimizing contact between the three and the dirt inside the pipe 12. Protective sleeves can be installed on both the power supply block 44 and the conductive block 45. The protective sleeves expose only the side of the power supply block 44 and the conductive block 45 that is in contact with each other. When the power supply block 44 and the conductive block 45 come into contact with each other, the two protective sleeves will wrap around the power supply block 44 and the conductive block 45 together to achieve a better protective isolation effect.
[0053] like Figure 2 and Figure 6 As shown, the interior of the mounting rod 2 is hollow. The end of the mounting rod 2 furthest from the scraper unit 7 is connected to a water inlet pipe 27. The side wall of the mounting rod 2 has spray holes 28 that connect to its interior. When the flow-assisting device travels inside the pipe 12, external water can enter the mounting rod 2 through the water inlet pipe 27 and be sprayed through the spray holes 28 onto the scraper body 72, the brush body 82, and the inner wall of the pipe 12, thus achieving spray cleaning of all three.
[0054] Below the mounting rod 2 is a collection unit 9 located between the brush unit 8 and the limiting unit 5. The collection unit 9 includes a fourth elastic telescopic component 91 filled with fluid. The structure of the fourth elastic telescopic component 91 is the same as that of the first elastic telescopic component 51.
[0055] The fixed end of the fourth elastic telescopic component 91 is installed on the bottom side wall of the mounting rod 2. The telescopic end of the fourth elastic telescopic component 91 is connected to the collection box 92. The fourth elastic telescopic component 91 is connected to the inside of the mounting shell 41 through the fourth flexible hose 93. One end of the collection box 92 is open and faces the scraper unit 7. The other end of the collection box 92 is connected to the guide pipe 94. One end of the guide pipe 94 can extend out of the pipe 12 and be connected to the external pump.
[0056] When the limiting plate 52 abuts against the inner wall of the pipe 12 and causes the fluid to flow from the first elastic telescopic component 51 into the mounting shell 41, some of the fluid in the mounting shell 41 will flow into the fourth elastic telescopic component 91. The fourth elastic telescopic component 91 will extend and cause the collection box 92 to automatically descend and abut against the bottom wall of the pipe 12 of different sizes. Under the suction of the external water pump, the sewage mixed with dirt flushed onto the bottom wall of the pipe 12 will be discharged out of the pipe 12 through the collection box 92 and the guide pipe 94, thereby realizing the simultaneous cleaning of dirt and sewage discharge.
[0057] like Figure 1 and Figure 2 As shown, the mounting rod 2 is provided with a bracket 1 at one end where the limiting unit 5 is located. Multiple limiting posts 291 are installed on the bracket 1. Several limiting grooves 29 extending along the axial direction of the mounting rod 2 are provided on the side wall of the mounting rod 2. The limiting posts 291 are slidably embedded in the limiting grooves 29, thereby limiting the movement direction of the mounting rod 2.
[0058] like Figures 2 to 4 As shown, the bracket 1 is provided with several clamping units 10 arranged circumferentially around the axis of the mounting rod 2 and several clamping units 11 arranged circumferentially around the axis of the mounting rod 2. All clamping units 10 are used to jointly clamp the end of the pipe 12, and all clamping units 11 are used to jointly clamp the side of the pipe 12, so that the bracket 1 is stably fixed on the pipe 12, ensuring that the mounting rod 2, which is slidably connected to the bracket 1, can be arranged coaxially with the pipe 12, so that the mounting rod 2 can move along the axial direction of the pipe 12 and enter the pipe 12 for cleaning.
[0059] The clamping unit 10 includes a clamping plate 102 connected to the bracket 1 via a fluid-filled sixth elastic telescopic component 101. The fixed end of the sixth elastic telescopic component 101 is mounted on the bracket 1, and the telescopic end of the sixth elastic telescopic component 101 is connected to the clamping plate 102. A fluid-filled second storage bladder 103 is mounted on the clamping plate 102. A support plate 104 is mounted on one end of the clamping plate 102 facing the axis of the mounting rod 2. A pressure sensor 105 is mounted on the support plate 104, and the pressure sensor 105 is coupled to a processor.
[0060] The clamping unit 11 includes a fifth elastic telescopic component 111 filled with fluid and connected to the second storage bladder 103 via a fifth hose 112. The fixed end of the fifth elastic telescopic component 111 is mounted on the bracket 1, and the telescopic end of the fifth elastic telescopic component 111 is mounted with a clamping plate 113. A third storage bladder 114 filled with fluid is mounted on the clamping plate 113, and the third storage bladder 114 is connected to the sixth elastic telescopic component 101 via a sixth hose 115.
[0061] Before cleaning the dirt, the worker holds the support 1 and inserts the end of the mounting rod 2 with the scraper unit 7 into the pipe 12. Then the worker adjusts the position of the support 1 so that all the clamping plates 102 are pressed against the end of the pipe 12. At this time, the second storage bladder 103 on the clamping plate 102 will be squeezed and compressed by the end of the pipe 12. The fluid in the second storage bladder 103 will enter the fifth elastic telescopic component 111 through the fifth hose 112. The fifth elastic telescopic component 111 will extend and cause the clamping plate 113 to move and press against the outer wall of the pipe 12 of different sizes.
[0062] Then the third storage bladder 114 on the clamp 113 will be squeezed and compressed by the outer wall of the pipe 12. The fluid in the third storage bladder 114 will enter the sixth elastic telescopic component 101 through the sixth hose 115. The sixth elastic telescopic component 101 will shorten and cause the abutment plate 102 to move away from the axis of the pipe 12. The abutment plate 102 will drive the support plate 104 to move and press against the inner wall of the pipe 12. The support plate 104, clamp 113 and abutment plate 102 cooperate with each other to make the bracket 1 stably fixed on the pipe 12, so as to ensure that the installation rod 2 can stably enter the pipe 12.
[0063] When the support plate 104 is pressed against the inner wall of the pipe 12, the pressure sensor 105 will also press against the inner wall of the pipe 12 and send a signal to the processor. The processor will then activate the drive device that controls the movement of the traction mounting rod 2. The drive device will detach the traction mounting rod 2 from the bracket 1 and gradually penetrate into the pipe 12 to achieve automatic cleaning of dirt inside the pipe 12.
[0064] The implementation principle of a flow aid device for reducing transport residue in pipeline transportation according to an embodiment of this application is as follows: When cleaning dirt, the worker first inserts the end of the mounting rod 2 with the scraper unit 7 into the pipe 12, and then all the clamping plates 102 on the bracket 1 are pressed against the end of the pipe 12. The second storage bladder 103 on the clamping plate 102 will be squeezed and compressed by the end of the pipe 12. The fluid in the second storage bladder 103 will enter the fifth elastic telescopic component 111 through the fifth hose 112. The fifth elastic telescopic component 111 will extend and cause the clamping plate 113 to move and press against the outer wall of the pipe 12 of different sizes.
[0065] Then the third storage bladder 114 on the clamp 113 will be squeezed and compressed by the outer wall of the pipe 12. The fluid in the third storage bladder 114 will enter the sixth elastic telescopic component 101 through the sixth hose 115. The sixth elastic telescopic component 101 will shorten, causing the clamping plate 102 to move away from the axis of the pipe 12. The clamping plate 102 will drive the support plate 104 and the pressure sensor 105 to move and press against the inner wall of the pipe 12, so that the bracket 1 is stably fixed on the pipe 12. The pressure sensor 105 will send a signal to the processor, and the processor will control the drive device to move the traction mounting rod 2. The drive device will pull the traction mounting rod 2 away from the bracket 1 and gradually penetrate into the pipe 12.
[0066] The folded end of the limiting plate 52 will abut against the inner wall of the end of the pipe 12 and gradually move closer to the axis of the mounting rod 2. The fluid in the first elastic telescopic component 51 will flow into the mounting shell 41 through the first hose 53. Due to its own rebound force, the elastic ball 55 on the limiting plate 52 will roll and press against the inner wall of the pipe 12, so that the flow aid device can move stably in the pipe 12.
[0067] The fluid entering the mounting housing 41 causes the slider 42 to slide within the housing 41 and causes the conductive block 45 to contact the power supply block 44. The power supply 43 supplies power to the motor 61 through the power supply block 44 and the conductive block 45. The motor 61 drives the sleeve 3 to rotate through the gear 62 and the internal gear ring 63. The sleeve 3 drives the scraper body 72 and the brush body 82 to rotate. Due to the centrifugal force of the scraper body 72, the second elastic telescopic component 71 will extend. The fluid in the first storage bladder 22 will enter the second elastic telescopic component 71 through the second hose 23, so that the second elastic telescopic component 71 can stably support the scraper body 72 against the pipes of different sizes 1. 2. On the inner wall, the scraper 73 and scraper body 72 will rotate and scrape away the dirt adhering to the inner wall of the pipe 12; the third elastic telescopic component 81 will extend due to the centrifugal force of the brush body 82, and the fluid in the first storage bladder 22 will enter the third elastic telescopic component 81 through the second hose 23 and the third hose 24, so that the third elastic telescopic component 81 can stably support the brush body 82 against the inner wall of the pipe 12 of different sizes, and the brush body 82 will rotate and brush away the dirt adhering to the inner wall of the pipe 12; the scraper body 72 and the brush body 82 cooperate with each other to reduce the amount of material residue inside the pipe 12, thereby achieving a better flow-aiding effect.
[0068] Meanwhile, external water will enter the mounting rod 2 through the inlet pipe 27 and be sprayed onto the scraper body 72, brush body 82 and inner wall of pipe 12 through the spray hole 28. Part of the fluid entering the mounting shell 41 from the first elastic telescopic component 51 will flow into the fourth elastic telescopic component 91. The fourth elastic telescopic component 91 will extend and cause the collection box 92 to automatically descend and abut against the bottom wall of pipe 12 of different sizes. Under the suction of the external water pump, the sewage mixed with dirt washed onto the bottom wall of pipe 12 will be discharged out of pipe 12 through collection box 92 and guide pipe 94.
[0069] In summary, during the cleaning process, the worker only needs to insert the end of the mounting rod 2 equipped with the scraper unit 7 into the pipe 12 and cause all the clamping plates 102 to press against the end of the pipe 12. This allows the clamping plates 102, support plates 104, and clamping plates 113 to lock and fix the bracket 1 onto the pipe 12, ensuring that the automatically activated drive equipment can pull the mounting rod 2 stably into the pipe 12. The elastic ball 55 will automatically press against the inner wall of the pipe 12 of different sizes, allowing the flow-assisting equipment to move stably forward within the pipe 12. The motor 61 will... The system automatically starts and causes the scraper 73, scraper body 72, and brush body 82 to clean the dirt on the inner wall of pipes 12 of different sizes. The clean water sprayed from the spray hole 28 will rinse the scraper body 72, brush body 82, and inner wall of pipe 12. Under the suction of the external water pump, the sewage mixed with dirt washed onto the inner bottom wall of pipe 12 will be discharged outside pipe 12 through collection box 92 and guide pipe 94, reducing the amount of material residue inside pipe 12 and preventing the inner diameter of pipe 12 from becoming smaller due to dirt accumulation, thereby achieving the effect of assisting flow.
[0070] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
