Description

Technical Field

[0001] This invention relates to the field of petroleum technology, specifically to a cleaning robot used in oil pipelines. Background Technology

[0002] Petroleum refers to a mixture of gaseous, liquid, and solid hydrocarbons, occurring naturally. Petroleum is further classified into crude oil, natural gas, liquefied natural gas, and natural tar, but the term "petroleum" is conventionally used to define "crude oil." Petroleum is a viscous, dark brown liquid, often referred to as the "blood of industry." Petroleum reserves are found in parts of the Earth's upper crust. Its main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. It is one of the primary targets of geological exploration.

[0003] Currently, automated cleaning robots are used in oil pipelines to clean the pipe walls. However, after a period of use, the pipeline needs to be disassembled and the batteries replaced, which is complex, tedious, and costly. Therefore, it is necessary to design a cleaning robot for oil pipelines that is highly practical and can partially shake off the oil stains adhering to the surface of the sliding scraper ring, thereby improving the cleaning effect of the sliding scraper ring surface and ensuring that the cleaning power of the sliding scraper ring on the inner wall of the oil pipeline is not affected. Summary of the Invention

[0004] The purpose of this invention is to provide a cleaning robot for use in oil pipelines to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a cleaning robot for oil pipelines, comprising an oil pipeline, wherein the inner wall of the oil pipeline is provided with a sliding cleaning mechanism and a brushing mechanism;

[0006] The sliding cleaning mechanism includes:

[0007] A fixing ring, which is a circular ring structure, has its outer wall fixedly connected to the inner wall of the oil pipeline, and has an elastic rope fixedly connected to its outer wall. The fixing ring is used for internal oil flow and to stabilize the elastic rope.

[0008] The push ring is a circular ring structure. The outer wall of the push ring is in contact with the inner wall of the oil pipeline. The outer wall of the push ring is fixedly connected to one end of an elastic rope. The push ring is slidably connected to a sliding rod. The push ring is used to slide on the inner wall of the oil pipeline under oil pressure.

[0009] The baffle is a circular disc structure. The outer wall of the baffle is fixedly connected to one end of the sliding rod. A spring is fixedly connected to the outer wall of the baffle. One end of the spring is fixedly connected to the outer wall of the push ring, and the other end of the spring is fixedly connected to the outer wall of the baffle. The baffle is used to fix the spring so that it can rebound.

[0010] According to the above technical solution, a connecting sleeve is slidably connected to the inner wall of the push ring, a connecting plate is fixedly connected to the outer wall of the connecting sleeve, a fixing block is fixedly connected to the outer wall of the connecting plate, a bearing ring is fixedly connected to the inner wall of the connecting sleeve, a magnetic block A is provided inside the connecting sleeve, and a magnetic block B is fixedly connected to the inner wall of the push ring, so that they are attracted to each other by magnetism and stabilized together. They will only be pushed apart when the pushing force is greater than the magnetic attraction force.

[0011] According to the above technical solution, a connecting rod is fixedly connected to the outer wall of the connecting sleeve, and a sliding scraper ring is fixedly connected to one end of the connecting rod. The outer wall of the sliding scraper ring contacts the inner wall of the oil pipeline, thereby scraping the inner wall of the oil pipeline.

[0012] According to the above technical solution, the brushing mechanism includes a rotating shaft, with both ends of the rotating shaft fixedly connected to the inner wall of the bearing ring, and an arc-shaped plate fixedly connected to the outer wall of the rotating shaft. The outer wall of the arc-shaped plate is fixedly connected to the outer wall of the magnetic block A, and a fan blade is fixedly connected to the outer wall of the rotating shaft, thereby rotating the fan blade to separate the oil.

[0013] According to the above technical solution, the outer wall of the fixing block is provided with a groove, and the inner wall of the groove is fixedly connected with elastic bristles, one end of which is fixedly connected to the inner wall of the groove.

[0014] According to the above technical solution, magnetic block A and magnetic block B are magnetic, and the magnetic properties of opposite sides of magnetic block A and magnetic block B are magnetic properties of opposite poles attracting each other, thus attracting each other stably through magnetic attraction.

[0015] According to the above technical solution, the elastic rope is made of rubber and has elasticity. The elastic force of the spring is greater than that of the elastic rope, so that the elastic rope is first pulled and the pressure increases before it begins to be squeezed and deformed.

[0016] According to the above technical solution, the fan blade surface is a curved shape, so that when liquid flows over it, it can be rotated by the curvature of the fan blade surface.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0018] 1. This invention, by setting up a sliding cleaning mechanism, uses a sliding scraper ring to scrape the inner wall of the oil pipeline, removing oil stains adhering to the inner wall. When there is no oil flow and no pressure, the push ring is pulled back by the elastic tension of the elastic rope. Thus, while oil is flowing, a long section of the inner wall of the oil pipeline can be comprehensively scraped in real time, removing all oil stains adhering to the inner wall of the oil pipeline with the sliding scraper ring, keeping the inner wall of the oil pipeline clean, avoiding the problem of blockage caused by excessive oil adhesion, and preventing the oil from accumulating for too long and deteriorating, thus affecting the quality of the flowing oil.

[0019] 2. This invention, by setting up a sliding cleaning mechanism, allows a large amount of oil to be discharged through the notch. Simultaneously, it pushes open the arc-shaped plate in the bearing ring inside the connecting sleeve, causing the arc-shaped plate to drive the rotating shaft to rotate and open the notch in the middle of the connecting sleeve. Oil is then discharged synchronously through the notch between the connecting sleeve and the connecting plate and the sliding scraper ring, achieving automatic oil flow. Furthermore, the rapid extension of the sliding scraper ring removes the residue adhering to its surface through the spring force and inertia, partially shaking off the oil stains adhering to the surface of the sliding scraper ring. This improves the cleaning effect of the sliding scraper ring surface while ensuring that the cleaning power of the sliding scraper ring on the inner wall of the oil pipeline is not affected.

[0020] 3. This invention, by setting up a sliding cleaning mechanism, after the oil flow is stopped, the sliding rod on the outer wall of the connecting plate is pulled back by the elastic force of the spring, and the push ring is also pulled back to its original position by the elastic rope, and everything is reset. During the reset, the notch between the sliding scraper ring and the connecting plate is embedded in the outer wall of the fixing block, and the fixing block scrapes the sliding scraper ring, preventing the sliding scraper ring from scraping the inner wall of the oil pipeline. This prevents the problem of excessive oil stains adhering to the surface from overflowing and being unable to be cleaned. The inner wall of the sliding scraper ring is cleaned to prevent the excessive spread of oil stains.

[0021] 4. This invention, through the setting of a brushing mechanism, ensures that the sliding scraper ring scrapes and cleans the outer wall of the fixed block both when it is pushed out of the fixed block and when it returns to the outer wall of the fixed block. The scraper ring also contacts the elastic bristles on the inner wall of the groove on the outer wall of the fixed block, and the elastic bristles, due to their own elasticity, clean the connecting rod from all directions. When the elastic bristles are moved by the connecting rod, they retract into the groove on the fixed block, ensuring the stable and unobstructed movement of the connecting rod. The movement of the elastic bristles also achieves a cleaning and shaking effect, removing all oil stains and dispersing them into the flowing oil, rather than adhering to the inner wall and causing blockages that affect oil flow.

[0022] 5. By setting up a brushing mechanism, the oil flow pressure is relatively high and the flow rate is relatively fast, which agitates the fan blades on the outer wall of the rotating shaft. When the rotating shaft and the arc plate are in the open state, the fan blades are agitated by the oil flow and rotate through the bearing ring on the inner wall of the connecting sleeve. Through the curved surface of the fan blades, the oil flow is in a rotating state and impacts the fan blades, which fully disperses and mixes the flowing oil, further improving the mixing effect of the oil during flow and preventing the accumulation and adhesion caused by sedimentation.

[0023] 6. This invention, by setting up a brushing mechanism, uses the rapid rotation of the arc-shaped plate and the rotating shaft to fling off the oil stains adhering to the surface of the arc-shaped plate with the centrifugal force of rotation, thus keeping the arc-shaped plate and the rotating shaft clean at all times. In addition, the inner wall of the bearing ring is scraped once every time the arc-shaped plate opens and closes, ensuring that the opening in the bearing ring is not blocked, thus ensuring the stability of operation inside the oil pipeline in all aspects and improving the cleaning effect on the inner wall of the oil pipeline.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Example 1, please refer to Figure 1-4 The present invention provides a technical solution: a cleaning robot for use in oil pipelines, including an oil pipeline 2, wherein a sliding cleaning mechanism 3 and a brushing mechanism 4 are provided on the inner wall of the oil pipeline 2;

[0041] The sliding cleaning mechanism 3 includes:

[0042] The fixing ring 301 is a circular ring structure. The outer wall of the fixing ring 301 is fixedly connected to the inner wall of the oil pipeline 2. An elastic rope 302 is fixedly connected to the outer wall of the fixing ring 301. The fixing ring 301 is used to flow oil internally and to stabilize the elastic rope 302.

[0043] Push ring 303 is a circular ring structure. The outer wall of push ring 303 is in contact with the inner wall of oil pipeline 2. The outer wall of push ring 303 is fixedly connected to one end of elastic rope 302. Push ring 303 is slidably connected to sliding rod 304. Push ring 303 is used to slide on the inner wall of oil pipeline 2 under oil pressure.

[0044] Baffle 306 is a circular disc structure. The outer wall of baffle 306 is fixedly connected to one end of sliding rod 304. A spring 305 is fixedly connected to the outer wall of baffle 306. One end of spring 305 is fixedly connected to the outer wall of push ring 303, and the other end of spring 305 is fixedly connected to the outer wall of baffle 306. Baffle 306 is used to fix spring 305 for rebound operation.

[0045] The sliding cleaning mechanism 3 and the brushing mechanism 4 are placed together inside a long oil pipeline 2. The fixing ring 301 is fixed to the inner wall of the oil pipeline 2 with bolts. After several oil pipelines 2 are connected normally, when oil is started flowing into the oil pipeline 2, the oil enters the push ring 303 through the inside of the fixing ring 301. The pressure of the oil pushes the push ring 303 to slide along the inner wall of the oil pipeline 2, simultaneously pushing the sliding scraper ring 313 on the outer wall of the push ring 303 to slide. The sliding scraper ring 313 scrapes the inner wall of the oil pipeline 2, removing the oil stains adhering to the inner wall of the oil pipeline 2. While scraping the inner wall of the oil pipeline 2, the elastic rope 302 connecting the push ring 303 and the fixed ring 301 is pulled, causing it to deform. When there is no oil flow and no pressure, the push ring 303 is pulled back by the elastic force of the elastic rope 302. This allows for real-time and comprehensive sliding scraping of a long section of the inner wall of the oil pipeline 2 during oil flow, removing all oil stains that adhere to the inner wall of the oil pipeline 2 with the sliding scraping ring 313, keeping the inner wall of the oil pipeline 2 clean, avoiding the problem of blockage caused by excessive oil adhesion, and preventing the accumulation of oil over a long period of time from deteriorating and affecting the quality of the flowing oil.

[0046] Example 2, please refer to Figure 1-12 Based on Embodiment 1, the present invention provides a technical solution: a connecting sleeve 307 is slidably connected to the inner wall of the push ring 303, a connecting plate 308 is fixedly connected to the outer wall of the connecting sleeve 307, a fixing block 314 is fixedly connected to the outer wall of the connecting plate 308, a bearing ring 311 is fixedly connected to the inner wall of the connecting sleeve 307, a magnetic block A309 is provided inside the connecting sleeve 307, and a magnetic block B310 is fixedly connected to the inner wall of the push ring 303.

[0047] A connecting rod 312 is fixedly connected to the outer wall of the connecting sleeve 307. A sliding scraper ring 313 is fixedly connected to one end of the connecting rod 312. The outer wall of the sliding scraper ring 313 is in contact with the inner wall of the oil pipeline 2.

[0048] When the oil pusher ring 303 slides along the inner wall of the oil pipeline 2, it is stopped by a bolt at the bend when it reaches the joint. At this point, the pusher ring 303 cannot continue sliding. The internal pressure of the oil pipeline 2 continues to push the pusher ring 303. This pressure exceeds the magnetic attraction between magnetic block B310 and magnetic block A309 on the inner wall of the pusher ring 303, causing magnetic block A309 to disengage from magnetic block B310. Consequently, the connecting sleeve 307 connected to magnetic block A309 is quickly pushed out by the oil pressure, causing the connecting sleeve 307 and connecting plate 308 to move rapidly away from the pusher ring 303. This also causes the sliding rod 304 to slide synchronously along the inner wall of the pusher ring 303. The stop at one end of the sliding rod 304... The plate 306 deforms the spring 305 between the push ring 303 and the connecting sleeve 307. After the connecting plate 308 moves away from the push ring 303, a gap appears between the push ring 303 and the connecting plate 308, and a large amount of oil is discharged through the gap. At the same time, it pushes open the arc plate 402 in the bearing ring 311 in the inner wall of the connecting sleeve 307, so that the arc plate 402 drives the rotating shaft 401 to rotate, opening the gap in the middle of the connecting sleeve 307. Oil is discharged synchronously through the gap between the connecting sleeve 307 and the connecting plate 308 and the sliding scraper ring 313, realizing automatic oil flow. Furthermore, the sliding scraper ring 313 is quickly pushed out, and the residue adhering to the surface of the sliding scraper ring 313 is scraped off by the spring force and inertia of the spring 305 after the rapid push. The oil stains adhering to the surface of the sliding scraper ring 313 are partially shaken off, improving the cleaning effect of the surface of the sliding scraper ring 313, while ensuring that the cleaning power of the sliding scraper ring 313 on the inner wall of the oil pipeline 2 is not affected.

[0049] When the oil flow stops, the sliding rod 304 on the outer wall of the connecting plate 308 is pulled back by the elastic force of the spring 305. Similarly, the push ring 303 is also pulled back to its original position by the elastic rope 302, and everything is reset. During the reset, the notch between the sliding scraper ring 313 and the connecting plate 308 is embedded in the outer wall of the fixing block 314, and the fixing block 314 scrapes the sliding scraper ring 313 to prevent the sliding scraper ring 313 from scraping the inner wall of the oil pipeline 2. This prevents the problem of excessive oil stains adhering to the surface from overflowing and being impossible to clean. The inner wall of the sliding scraper ring 313 is cleaned to prevent the excessive oil stains from spreading.

[0050] Example 3, please refer to Figure 1-13 Based on Embodiment 1 and Embodiment 2, the present invention provides a technical solution: the brushing mechanism 4 includes a rotating shaft 401, the two ends of the rotating shaft 401 are fixedly connected to the inner wall of the bearing ring 311 respectively, an arc plate 402 is fixedly connected to the outer wall of the rotating shaft 401, the outer wall of the arc plate 402 is fixedly connected to the outer wall of the magnetic block A309, and a fan blade 403 is fixedly connected to the outer wall of the rotating shaft 401.

[0051] The outer wall of the fixing block 314 has a groove 404, and the inner wall of the groove 404 is fixedly connected to an elastic bristle 405, with one end of the elastic bristle 405 fixedly connected to the inner wall of the groove 404.

[0052] Magnetic block A309 and magnetic block B310 are magnetic, and the magnetic properties of opposite sides of magnetic block A309 and magnetic block B310 are magnetic properties of opposite poles attracting each other.

[0053] The elastic rope 302 is made of rubber and is elastic, and the elastic force of the spring 305 is greater than that of the elastic rope 302.

[0054] The surface of the fan blade 403 is a curved shape;

[0055] Meanwhile, when the sliding scraper ring 313 is pushed out of the fixed block 314 and when it returns to the outer wall of the fixed block 314, it will scrape and clean the outer wall of the fixed block 314. It will also contact the elastic bristles 405 on the inner wall of the groove 404 on the outer wall of the fixed block 314. The elastic bristles 405 will clean the connecting rod 312 in all directions with their own elasticity. When the elastic bristles 405 are moved by the connecting rod 312, they will retract into the groove 404 on the fixed block 314, ensuring the stable movement of the connecting rod 312 is not hindered. Moving the elastic bristles 405 will also achieve the same cleaning and shaking effect, cleaning all the oil stains and dispersing them into the flowing oil, instead of adhering to the inner wall and causing blockages that affect the flow of oil.

[0056] Meanwhile, as the rotating shaft 401 and the arc plate 402 are pushed open and oil flows continuously, the oil flow pressure is relatively high and the flow rate is relatively fast, which agitates the fan blades 403 on the outer wall of the rotating shaft 401. This causes the rotating shaft 401 and the arc plate 402 to rotate on the inner wall of the connecting sleeve 307 through the bearing ring 311 as the surface of the fan blades 403 is agitated by the oil flow. Through the curved surface of the fan blades 403, the oil flow is in a rotating state and impacts the fan blades 403, which fully disperses and mixes the flowing oil, further improving the mixing effect of the oil during flow and preventing the accumulation and adhesion caused by sedimentation.

[0057] At the same time, the rapid rotation of the arc plate 402 and the rotating shaft 401 causes the oil stains adhering to the surface of the arc plate 402 to be thrown off by the centrifugal force of rotation, keeping the arc plate 402 and the rotating shaft 401 clean at all times. In addition, each time the arc plate 402 opens and closes, it will scrape the inner wall of the bearing ring 311 to ensure that the opening in the bearing ring 311 is not blocked, thus ensuring the stability of the operation inside the oil pipeline 2 in all aspects and improving the cleaning effect on the inner wall of the oil pipeline 2.

[0058] After the oil circulation ends, because one of the arc-shaped plates 402 is fixed with a magnetic block A309 on its outer wall, the two arc-shaped plates 402 on the outer wall of the rotating shaft 401 have different masses. The arc-shaped plate 402 with the larger mass rotates and descends. Therefore, it will slide to the lowest point under gravity while stationary. After the connecting sleeve 307 is pulled back by the elastic force of the spring 305, the magnetic block A309, when approaching the magnetic block B310, quickly magnetically attracts the magnetic block B310 to maintain the stability of the arc-shaped plate 402 and the rotating shaft 401. Thus, everything returns to normal, and it will be reopened for the next oil circulation.
