Description

Technical Field

[0001] This invention relates to the field of pipeline inspection technology, and specifically to an automated pipeline X-ray inspection device. Background Technology

[0002] An automated pipeline X-ray inspection device is a device that integrates components such as X-ray sources and detectors. It uses X-rays to penetrate the pipe wall, thereby identifying defects in the pipe, such as weld cracks and corrosion.

[0003] Chinese patent CN221880669U discloses a pipeline inspection device, including a sealed waterproof housing. A control box is installed inside the sealed waterproof housing, and buffer wheels are installed on the four sides (top, bottom, front, and back) of the sealed waterproof housing. The buffer wheels are connected to the sealed waterproof housing via buffer cylinders. The aforementioned prior art uses a propeller to provide propulsion for the inspection device, and the buffer wheels ensure stable passage through pipelines with high water content. The cleaning mechanism is equipped with adjustable cleaning brushes and scrapers around its perimeter. Driven by a motor, these clean the inner wall of the pipeline, and the cleaning is detected by a camera, thus improving the accuracy of pipeline inspection.

[0004] However, some pipes may have residual materials on their inner walls due to the materials being transported. These materials may accumulate inside the pipe and form protrusions. These protrusions may affect the passage of automated pipe X-ray inspection equipment and may also cause the X-rays emitted by the automated pipe X-ray inspection equipment to be blocked by the residual materials.

[0016] Preferably, the limiting component includes an elastic element three, a movable plate, a beveled portion three, and a beveled portion four;

[0017] The two ends of the elastic element three are connected to the mounting cylinder and the movable plate respectively; the inclined part three is installed above the movable plate and is located on the moving path of the inclined part two; the inclined part four is installed at the bottom of the movable plate and is located on the moving path of the inclined part one; the scraper drives the inclined part one to descend and pushes the inclined part four.

[0018] Preferably, the locking assembly includes a first locking plate, a fourth elastic element, and a second locking plate;

[0019] The two ends of the elastic element four are respectively connected to the elastic element four and the movable plate; the snap-fit ​​plate one is installed at the bottom of the inclined part four; the snap-fit ​​plate one and the snap-fit ​​plate two are snap-fitted together.

[0020] Preferably, the reset assembly includes a second drive device, a take-up roller, and a pull rope;

[0021] The second drive device is installed in the inner cavity of the movable plate, and its output shaft is equipped with a take-up roller; the two ends of the pull rope are respectively connected to the second snap-fit ​​plate and the take-up roller.

[0022] Preferably, the spraying mechanism includes a water supply assembly, a sleeve, a circular pipe, a spray head, and a rotating unit;

[0023] The water supply component is connected inside the detection mechanism of the detection device body. The sleeve connects the water supply component and is sleeved at the connection between the first round pipe and the T-shaped rod. The two ends of the second round pipe are respectively connected to the first round pipe and the spray head. The second round pipe and the spray head are movably connected. The spray head is connected to the rotating unit.

[0024] Preferably, the rotating unit includes a connecting rod, a gear, a cylinder, a coil spring, and an arc-shaped rack;

[0025] The cylinder is installed outside the support; the coil spring is connected inside the cylinder; the connecting rod connects the center of the coil spring and the spray head; the gear is installed on the connecting rod; the arc-shaped rack is installed on the detection mechanism and is located on the movement path of the gear.

[0026] Preferably, the testing mechanism includes a testing device body, a mounting frame, and electric wheels;

[0027] The mounting bracket is installed on the outside of the detection device body, and the electric wheels are mounted on the mounting bracket.

[0028] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects:

[0029] The drive unit is activated, causing the T-shaped rod, the round pipe, and the support to rotate. The cleaning brush cleans the inner wall of the pipe, and then water is sprayed onto the inner wall of the pipe through the spray head, thus cleaning the inner wall of the pipe and preventing debris on the pipe from affecting the normal passage or normal detection of the detection device.

[0030] When the scraper comes into contact with a protrusion inside the pipe, it is pressed down by the protrusion, causing it to move towards the first elastic element. At this time, the first inclined section comes into contact with the fourth inclined section, which in turn moves the fourth inclined section a distance away from the first inclined section before being locked again by the second locking plate. The third inclined section moves a distance towards the second inclined section along with the fourth inclined section, and is now located on the movement path of the second inclined section. Subsequently, the scraper separates from the protrusion, and the elasticity of the first elastic element causes the scraper to move upward and reset. At this time, the second inclined section comes into contact with the third inclined section, and the elasticity of the second elastic element causes the scraper to move upward and reset. The second inclined section passes over the third inclined section, and then the horizontal surfaces of the second and third inclined sections come into contact. This means that when the scraper comes into contact with the protrusion again, the second inclined section cannot descend because the horizontal surfaces of the second and third inclined sections are in contact. As a result, the scraper quickly removes the protrusion. This ensures that the scraper only makes close contact with the inner wall of the pipe when it is facing a protrusion. Under normal circumstances, the elasticity of the first elastic element allows the scraper to be flexibly connected to the inner wall of the pipe, avoiding the scraper from scratching or damaging the inner wall of the pipe during normal use.

[0031] Water is delivered to the spray head through the water supply assembly, sleeve, round pipe one, and round pipe two. The spray head sprays water onto the inner wall of the pipe, thereby flushing away debris and wetting the inner wall to facilitate subsequent cleaning. Then, as the support rotates, it drives the gear to rotate around the movable plate as the axis, so that the gear intermittently meshes with the arc-shaped rack, driving the gear to rotate and the spray head to rotate towards the cleaning brush, thereby cleaning and flushing the cleaning brush and preventing debris from accumulating on the cleaning brush and affecting its cleaning effect.

[0042] Example 1, as Figure 1-9 As shown, the automated pipeline X-ray inspection device proposed in this invention includes an inspection mechanism and a support unit 7; it also includes:

[0043] A cleaning mechanism, which is mounted on the support 7;

[0044] A spraying mechanism, which is mounted on the support 7, is used to spray water onto the inner wall of the pipe;

[0045] The cleaning mechanism includes a drive assembly, a sweeping assembly, a scraping assembly, a limiting assembly, a locking assembly, a reset assembly, and a mounting cylinder 10. The drive assembly is installed in the cleaning mechanism. The rotating end of the drive assembly is connected to the support part 7. The sweeping assembly is installed outside the support part 7 and is used to sweep away debris from the inner wall of the pipe. The mounting cylinder 10 is installed outside the support part 7, and the scraping assembly is installed inside the mounting cylinder 10. The limiting assembly is installed inside the mounting cylinder 10 and is used to limit the scraping assembly so that it scrapes the inner wall of the pipe. The locking assembly is installed inside the mounting cylinder 10 and is used to engage with the limiting assembly. The reset assembly is installed inside the support part 7 and is used to reset the locking assembly after engagement. When the scraping assembly is blocked by a protrusion on the inner wall of the pipe, the limiting assembly moves to limit the scraping assembly, so that the scraping assembly scrapes away the protrusion on the inner wall of the pipe.

[0046] The drive assembly includes a drive device 4, a T-shaped rod 5, a round tube 6, a T-shaped plate 8, and a T-shaped slide 9;

[0047] The drive device 4 is installed inside the detection mechanism. The two ends of the T-shaped rod 5 are respectively connected to the output shaft of the drive device 4 and the round tube 6. The support part 7 is installed on the outside of the round tube 6. The T-shaped plate 8 is installed on the outside of the support part 7. The T-shaped groove 9 is opened on the detection mechanism, and the T-shaped plate 8 is slidably connected in the T-shaped groove 9.

[0048] There are four T-shaped plates 8, which are slidably connected in the T-shaped groove 9, improving the stability of the drive device 4 during the rotation of the support part 7 and preventing the support part 7 from deviating during rotation.

[0049] The cleaning components include a flexible element 26 and a cleaning brush 27;

[0050] The two ends of the elastic element 5 26 are respectively connected to the support part 7 and the cleaning brush 27; the cleaning brush 27 rotates with the support part 7.

[0051] When the cleaning brush 27 comes into contact with the inner wall of the pipe, or when it comes into contact with protrusions inside the pipe, the elasticity of the elastic element 26 allows the cleaning brush 27 to move, thus preventing the cleaning brush 27 from being blocked and damaged by the protrusions.

[0052] The scraping assembly includes an elastic element 11, a scraper 12, a beveled part 13, an elastic element 2 14, and a beveled part 2 15;

[0053] The two ends of the elastic element 11 are respectively connected to the support part 7 and the scraper 12; the scraper 12 is movably connected inside the mounting cylinder 10; the inclined part 13 is installed at the bottom of the scraper 12; the two ends of the elastic element 2 14 are respectively connected to the scraper 12 and the inclined part 2 15.

[0054] The bottom end of the scraper 12 is provided with a rectangular groove, which is located above the connection between the movable plate 17 and the inclined surface 19. When the scraper 12 descends, the scraper 12 will not contact the movable plate 17, while the inclined surface 13 will contact the inclined surface 19, thereby driving the inclined surface 19 to move away from the inclined surface 18.

[0055] The limiting assembly includes elastic element 3 16, movable plate 17, inclined part 3 18 and inclined part 4 19;

[0056] The two ends of the elastic element 16 are connected to the mounting cylinder 10 and the movable plate 17 respectively; the inclined part 18 is installed above the movable plate 17 and is located on the moving path of the inclined part 2 15; the inclined part 4 19 is installed at the bottom of the movable plate 17 and is located on the moving path of the inclined part 13; the scraper 12 drives the inclined part 13 to descend and push the inclined part 4 19.

[0057] When scraper 12 is blocked by a protrusion in the pipe, scraper 12 retracts a certain distance into the inner cavity of mounting cylinder 10, thereby compressing and storing force in elastic element 11. When scraper 12 moves downward, inclined surface 13 contacts inclined surface 19. At this time, the inclined surface of inclined surface 13 and the inclined surface of inclined surface 19 are in contact. When inclined surface 19 is moved away from elastic element 16, elastic element 16 is compressed and stored. At this time, inclined surface 18 moves to inclined surface 11. Above 5, the scraper 12 then rises, and the inclined surface of the second inclined surface 15 contacts the inclined surface of the third inclined surface 18, so that the second inclined surface 15 is pushed into the scraper 12 by the third inclined surface 18. The second inclined surface 15 extends out of the inner cavity of the scraper 12 through the elasticity of the second elastic element 14. At this time, the horizontal surface of the second inclined surface 15 and the horizontal surface of the third inclined surface 18 are in contact, limiting and fixing the position of the scraper 12, so that the elasticity of the first elastic element 11 can no longer pull the scraper 12 down.

[0058] The locking assembly includes a snap-fit ​​plate 20, an elastic element 21, and a snap-fit ​​plate 22;

[0059] The two ends of the elastic element 4 21 are respectively connected to the elastic element 4 21 and the movable plate 17; the snap-fit ​​plate 1 20 is installed at the bottom end of the inclined part 4 19; the snap-fit ​​plate 1 20 and the snap-fit ​​plate 2 22 are snapped together.

[0060] When the inclined surface 19 is not pushed by the inclined surface 13, the locking plate 22 engages with the locking plate 20, thereby limiting the positions of the movable plate 17, the inclined surface 18, and the inclined surface 19. When the inclined surface 13 contacts the inclined surface of the inclined surface 19, the inclined surface 13 pushes the inclined surface 19 away from the elastic element 16, thereby causing the inclined surface 18 to move towards the inclined surface 15 and above the inclined surface 15; at this time, the inclined surface 19... The snap-fit ​​plate 20 at the bottom of the face part 4 19 moves with the face part 4 19. Due to the elasticity of the elastic element 4 21, the elastic element 4 21 can also push the snap-fit ​​plate 2 22 downward a certain distance when it moves, and then snap-fit ​​with the snap-fit ​​plate 2 22 again, thereby completing the fixation of the position of the face part 3 18. This allows the face part 3 18 to limit the height of the face part 2 15, thereby limiting the position of the scraper 12, so that the scraper 12 can remove the protrusions on the inner wall of the pipe.

[0061] The reset assembly includes drive device 23, take-up roller 24, and pull rope 25;

[0062] The second drive device 23 is installed in the inner cavity of the movable plate 17, and its output shaft is equipped with a take-up roller 24; the two ends of the pull rope 25 are respectively connected to the second snap-fit ​​plate 22 and the take-up roller 24.

[0063] After the scraper 12, fixed by the inclined section 3 18, removes protrusions from the pipe, and when the scraper 12 no longer needs to remove protrusions, the drive device 23 is activated to drive the take-up roller 24 to rotate. The rotation of the take-up roller 24 winds up the pull rope 25, thereby pulling the locking plate 22 downward. At this time, the locking plate 20 at the bottom of the inclined section 4 19 separates from the locking plate 22, causing the inclined section 4 19 to lose its limit. At this time, the elasticity of the elastic element 3 16 drives the movable plate 17 to move in the direction of the elastic element 3 16. Then, the inclined section 3 18 moves away from below the inclined section 2 15, thereby allowing the scraper 12 to regain its elasticity. This prevents the scraper 12 from contacting the inner wall of the pipe during daily use, avoiding damage to the inner wall of the pipe caused by the scraper 12 scraping the inner wall forcefully for a long time. The scraper 12 will only be locked and function when facing protrusions.

[0064] Example 2, as Figure 2 , 4 As shown in Figure 8, the automated pipeline X-ray inspection device proposed in this invention, compared with Embodiment 1, the spray mechanism of this embodiment includes a water conveying component 28, a sleeve 29, a circular pipe 30, a spray head 31 and a rotating unit;

[0065] The water supply component 28 is connected inside the detection mechanism of the detection device body 1. The sleeve 29 connects to the water supply component 28 and is sleeved at the connection between the first round pipe 6 and the T-shaped rod 5. The two ends of the second round pipe 30 are respectively connected to the first round pipe 6 and the spray head 31. The second round pipe 30 and the spray head 31 are movably connected. The spray head 31 is connected to the rotating unit.

[0066] The rotating unit includes a connecting rod 32, a gear 33, a cylinder 34, a coil spring 35, and an arc-shaped rack 36;

[0067] The cylinder 34 is installed outside the support 7; the coil spring 35 is connected inside the cylinder 34; the connecting rod 32 connects the center of the coil spring 35 and the spray head 31; the gear 33 is installed on the connecting rod 32; the arc-shaped rack 36 is installed on the detection mechanism and is located on the moving path of the gear 33.

[0068] The water delivery assembly 28 consists of a water delivery pipe and a water pump.

[0069] The external water supply pipe is connected to the water supply assembly 28. The water supply assembly 28 then transports water along the water supply assembly 28 and the sleeve 29 to the first round pipe 6, and then through the first round pipe 6 to the second round pipe 30, and then to the spray head 31. The spray head 31 then sprays the water onto the inner wall of the pipe. During the rotation of the support part 7, the gear 33 intermittently meshes with the arc-shaped rack 36, thereby driving the gear 33 to rotate. The gear 33 drives the connecting rod 32 to rotate, and the connecting rod 32 drives the coil spring 35 and the spray head 31 to rotate. At this time, the coil spring 35 rotates and contracts to store energy, and drives the spray head 31 to rotate in the direction of the cleaning brush 27 to rinse the cleaning brush 27. After the gear 33 separates from the arc-shaped rack 36, the coil spring 35 releases its elasticity, driving the spray head 31, the connecting rod 32 and the gear 33 to rotate and reset.

[0070] Example 3, as Figure 1-2 As shown, the automated pipeline X-ray inspection device proposed in this invention, compared with Embodiment 2, the inspection mechanism of this embodiment includes an inspection device body 1, a mounting frame 2 and an electric wheel 3;

[0071] Mounting bracket 2 is installed on the outside of the detection device body 1, and electric wheel 3 is installed on mounting bracket 2.

[0072] In summary, in this invention, the external water source pipe is connected to the water supply end of the water supply component 28. Then, the detection device body 1 moves along the inner wall of the pipe via the electric wheel 3 and moves slowly inside the pipe. Next, the drive device 4 is started to drive the T-shaped rod 5 to rotate, thereby driving the round pipe 6 to rotate. The round pipe 6 drives the support part 7 to rotate, and the support part 7 drives the mounting cylinder 10 and the elastic element 26 to rotate. The cleaning brush 27 is used to sweep away the debris on the inner wall of the pipe.

[0073] Simultaneously, the water delivery assembly 28 delivers water to the sleeve 29, and then through the water delivery assembly 28 and the sleeve 29, it is delivered to the inner cavity of the first circular pipe 6. Subsequently, it is delivered along the first circular pipe 6 to the second circular pipe 30 and the spray head 31. The water is then sprayed onto the inner wall of the pipe through the spray head 31. When the spray head 31 rotates with the support part 7, the gear 33 moves to the arc-shaped rack 36, which meshes with the gear 33, thereby driving the gear 33 to rotate. This, in turn, drives the connecting rod 32 to rotate. The connecting rod 32 drives the coil spring 35 to rotate and retract, storing energy, and also driving the spray head 31 to rotate. Because the spray head... The movable connection between the spray head 31 and the second round tube 30 allows water inside the second round tube 30 to still enter the spray head 31 and spray out from the spray head 31 when the spray head 31 rotates. Then the spray head 31 turns to the cleaning brush 27 to rinse the cleaning brush 27, thus avoiding the situation where there is too much debris on the cleaning brush 27 after cleaning the inner wall of the pipe for a long time. When the gear 33 separates from the arc rack 36, the coil spring 35 releases its elasticity, thereby driving the connecting rod 32, gear 33 and spray head 31 to rotate and reset, so that the spray head 31 faces the inner wall of the pipe again.

[0074] During daily use, scraper 12 does not contact the inner wall of the pipe. When scraper 12 comes into contact with the protrusions accumulated on the inner wall of the pipe, scraper 12 is blocked by the protrusions, causing scraper 12 to retract into the inner cavity of mounting cylinder 10. This causes elastic element 11 to retract and store force. Then scraper 12 drives inclined surface 13 to move toward elastic element 11. Inclined surface 13 contacts inclined surface 4 19, causing the inclined surface of inclined surface 13 to contact the inclined surface of inclined surface 4 19. This pushes inclined surface 4 19 away from elastic element 3 16, causing inclined surface 3 18 to move above inclined surface 2 15. During the movement of inclined surface 4 19, the locking plate 20 at the bottom of inclined surface 4 19 pushes the locking plate 2 22 downward and then re-engages the locking plate 20 with the locking plate 2 22, thereby limiting and fixing the moved inclined surface 4 19.

[0075] Next, the elastic element 11 releases its elasticity, causing the scraper 12 to rise. As the inclined section 15 rises, the inclined surface of the inclined section 15 contacts the inclined surface of the inclined section 18. Through the elasticity of the elastic element 14, the inclined section 15 contracts into the inner cavity of the scraper 12 and passes over the inclined section 18. At this time, the horizontal surface of the inclined section 15 contacts the horizontal surface of the inclined section 18. The inclined section 18 then blocks the inclined section 15, thus preventing the scraper 12 from descending and fixing its position. Subsequently, the scraper 12 scrapes away the protrusions on the inner wall of the pipe.

[0076] After the protrusions inside the pipe are scraped off, the drive device 23 is started to drive the take-up roller 24 to rotate. The take-up roller 24 rotates and retracts the pull rope 25. The pull rope 25 pulls the snap-fit ​​plate 22 towards the elastic element 4 21, thereby separating the snap-fit ​​plate 22 from the elastic element 4 21 at the bottom of the inclined section 4 19. Then, the elasticity of the elastic element 3 16 pulls the movable plate 17 towards the elastic element 3 16, thereby moving the inclined section 4 19 below the inclined section 13. The inclined section 3 18 separates from the inclined section 2 15 for the next use. Then, the detection device body 1 inspects the cleaned inner wall of the pipe.

[0077] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
