Abstract

[0002] Pipelines are devices used to transport gas, liquid or fluids with solid particles. The quality of pipelines is related to safety issues, so relevant quality inspection units need to regularly detect underground pipelines to prevent pipeline damage and leakage of transported fluids.
[0003] During the flaw detection process, the operator needs to hold the flaw detection equipment and move it from top to bottom at the mouth of the pipeline so that the flaw detection equipment can capture the inner wall of the pipeline through the mouth of the pipeline, and the inspector needs to observe the image transmitted to the computer in real time by the flaw detection equipment to determine whether the inner wall of the detected pipeline is damaged. In order to enable the flaw detection equipment to fully capture the inner wall of the pipeline, the operator needs to move the position of the flaw detection equipment after the inspector has viewed one image so that the inspector can view the next image. Since the inner diameter of the pipeline to be detected is large, the flaw detection process will consume a lot of physical strength of the operator. In addition, the existing flaw detection equipment requires at least one operator and at least one inspector to work together to complete the flaw detection work of the pipeline, so the flaw detection efficiency is low and the flaw detection cost is high.

[0022] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.
[0023] refer to Figures 1 to 3 A pipeline flaw detection device according to a preferred embodiment of the present invention will be described in detail below. The pipeline flaw detection device detects whether the inner wall of the pipeline 90 is damaged at the pipe mouth 901 of the pipeline 90.
[0024] Specifically, the pipeline flaw detection equipment includes a supporting mechanism 10 , a detecting mechanism 20 and at least one spacing adjustment mechanism 30 .
[0025] The supporting mechanism 10 includes a mounting portion 11 and two clamping portions 12. The detecting mechanism 20 includes an image acquisition component 21, wherein the image acquisition component 21 is mounted on the mounting portion 11.
[0026] The image acquisition component 21 acquires the inner wall image of the pipe 90 by aligning with the pipe opening 901. The image acquisition component 21 is in communication connection with the control unit 80, and the staff can view the inner wall image of the pipe 90 acquired by the image acquisition component 21 through the control unit 80, and then determine whether the inner wall of the pipe 90 is damaged.
[0027] The two clamping parts 12 are respectively installed at the two opposite ends of the mounting part 11, and a limited space 1201 is formed between the two clamping parts 12. Any of the clamping parts 12 is drivingly connected to the spacing adjustment mechanism 30, and the spacing adjustment mechanism 30 is used to adjust the distance between the two clamping parts 12, thereby adjusting the size of the limited space 1201. When one end of the pipe 90 forming the pipe mouth 901 moves into the limited space 1201 and the image acquisition component 21 is aligned with the pipe mouth 901, the spacing adjustment mechanism 30 drives the clamping part 12 connected thereto to approach the opposite clamping part 12, so that both the clamping parts 12 abut against the outer wall of the pipe 90. In this way, the two clamping parts 12 hold the pipe 90 tightly, so that the image acquisition component 21 does not need the staff to hold the pipeline flaw detection equipment in the process of collecting images, and the use is stable, convenient and labor-saving. The image collected by the image acquisition component 21 is clear, which is convenient for the staff to judge.
[0028] It is worth mentioning that due to the setting of the spacing adjustment mechanism 30, the size of the limiting space 1201 is adjustable, so the supporting mechanism 10 can clamp the pipes 90 of different diameters, so the pipeline flaw detection equipment can be applicable to various models of pipes 90.
[0029] Preferably, the mounting portion 11 forms an abutting wall 111. The abutting wall 111 faces the limiting space 1201. One end of the pipe 90 forming the pipe opening 901 moves into the limiting space 1201 and abuts against the abutting wall 111, so that the abutting wall 111 and the two clamping portions 12 cooperate to hold the pipe 90 tightly, thereby increasing the contact area between the pipeline flaw detection device and the pipe 90, and ensuring a stable connection between the pipeline flaw detection device and the pipe 90.
[0030] In one embodiment, one spacing adjustment mechanism 30 is provided. One of the clamping parts 12 is slidably mounted on one end of the mounting part 11, and the clamping part 12 is drivenly connected to the spacing adjustment mechanism 30. The other clamping part 12 is fixedly mounted on the other end of the mounting part 11. In this way, the spacing adjustment mechanism 30 drives the clamping part 12 connected thereto to move in a direction away from the other clamping part 12, so as to expand the limiting space 1201, so as to facilitate the movement of one end of the pipe 90 forming the pipe mouth 901 into or out of the limiting space 1201; the spacing adjustment mechanism 30 drives the clamping part 12 connected thereto to move in a direction close to the other clamping part 12, so as to reduce the limiting space 1201, so that the two clamping parts 12 clamp one end of the pipe 90 forming the pipe mouth 901, so that the pipeline flaw detection equipment is stably mounted on one end of the pipe 90, so as to facilitate the smooth operation of the detection mechanism 20.
[0031] As a deformable method, two spacing adjustment mechanisms 30 are provided, and the two clamping parts 12 are respectively slidably mounted on the opposite ends of the mounting part 11, and each of the clamping parts 12 is drivingly connected to one spacing adjustment mechanism 30.
[0032] Preferably, the mounting portion 11 further forms at least one movement limiting structure 112. The clamping portion 12 connected to the spacing adjustment mechanism 30 is slidably mounted on the movement limiting structure 112, the movement limiting structure 112 extends along the distribution direction of the two clamping portions 12, and the movement limiting structure 112 is used to limit the movement of the clamping portion 12 along its own extension direction.
[0033] In one example, the displacement limiting structure 112 is implemented as a groove or an optical axis.
[0034] In a preferred embodiment, the spacing adjustment mechanism 30 includes a first driving member 31 and a first screw rod 32. The clamping portion 12 is mounted on the first screw rod 32, and the axial direction of the first screw rod 32 is parallel to the extension direction of the limiting structure 112. The first screw rod 32 is connected to the first driving member 31 by driving, and the first driving member 31 is used to drive the first screw rod 32 to rotate. That is to say, when the first screw rod 32 is rotated by the first driving member 31, the clamping portion 12 moves along the axial direction of the first screw rod 32 under the limiting action of the limiting structure 112, so that the size of the limiting space 1201 is adjusted. In this embodiment, the first driving member 31 is implemented as a motor. It is worth mentioning that the spacing adjustment mechanism 30 is not only limited to being implemented as a motor screw mechanism, but can also be implemented as a cylinder, and its working principle is not described redundantly here.
[0035] Specifically, the image acquisition component 21 includes an image acquisition member 211 and a housing 212. The image acquisition member 211 is mounted on the housing 212, and the housing 212 is mounted on the mounting portion 11. The image acquisition member 211 acquires the inner wall image of the pipe 90 through the pipe opening 901.
[0036] In one example, the image acquisition component 211 is implemented as a camera, and the staff checks the damage of the inner wall of the pipeline 90 by viewing the image acquired in real time by the image acquisition component 211 through the control unit 80. The control unit 80 is implemented to include a computer.
[0037] Furthermore, the pipeline flaw detection equipment also includes a position adjustment mechanism 40 .
[0038] The housing 212 is configured to be slidably mounted on the mounting portion 11 in a direction perpendicular to the abutting wall 111. The housing 212 is drivingly connected to the position adjustment mechanism 40. The position adjustment mechanism 40 is configured to drive the housing 212 to move in a direction perpendicular to the abutting wall 111. In this way, when the abutting wall 111 and the two clamping portions 12 cooperate to hold the pipe 90 tightly, the position adjustment mechanism 40 drives the detection mechanism 20 to move in a cross-sectional direction perpendicular to the axis of the pipe 90.
[0039] It is understandable that the support mechanism 10 can hold the pipes 90 of different models, and the pipes 90 of different models have different diameters. Therefore, the position adjustment mechanism 40 drives the detection mechanism 20 to move along the cross-sectional direction perpendicular to the axis of the pipe 90, so that the detection mechanism 20 can be aligned with the pipe mouth 901, ensuring that the detection mechanism 20 can detect the inner wall of the pipes 90 of different diameters. It is worth mentioning that the position adjustment mechanism 40 adjusts the distance of the detection mechanism 20 relative to the top wall and the bottom wall of the pipe 90 by driving the detection mechanism 20 to move, so that the staff can adjust the position of the detection mechanism 20 according to the image captured by the image acquisition component 211 to fully detect the pipe 90.
[0040] Preferably, the mounting portion 11 forms at least one guide structure 113. The housing 212 is slidably mounted on the guide structure 113, and the guide structure 113 extends in a direction perpendicular to the abutting wall 111, and the guide structure 113 is used to limit the moving direction of the detection mechanism 20.
[0041] In one example, the guide structure 113 is implemented as a groove or an optical axis.
[0042] In a preferred embodiment, the position adjustment mechanism 40 includes a second drive member 41 and a second screw rod 42. The housing 212 is mounted on the second screw rod 42, and the axial direction of the second screw rod 42 is parallel to the extension direction of the guide structure 113. The second screw rod 42 is rotatably connected to the second drive member 41, and the second drive member 41 is used to drive the second screw rod 42 to rotate. That is, when the second screw rod 42 is rotated by the second drive member 41, the image acquisition component 21 moves along the axial direction of the second screw rod 42 under the limiting action of the guide structure 113 to adjust the position of the detection mechanism 20. In this embodiment, the second drive member 41 is implemented as a motor. It is worth mentioning that the position adjustment mechanism 40 is not only limited to being implemented as a motor screw mechanism, but can also be implemented as a cylinder, and its working principle is not described redundantly here.
[0043] Preferably, the detection mechanism 20 further includes at least one lighting element 22, which is mounted on the housing 212. The lighting element 22 is used for lighting to increase the brightness in the pipe 90 when the image acquisition element 211 acquires an image, so that the image acquisition element 211 can acquire a clear and bright image.
[0044] Preferably, the lighting element 22 is installed at an adjustable angle on the housing 212. That is, the staff can adjust the angle of the lighting element 22 according to the needs, so that the lighting element 22 can focus on illuminating a predetermined area of the inner wall of the pipe 90, so that the staff can clearly observe whether there is damage in the predetermined area.
[0045] In one example, the lighting element 22 is implemented as a light bulb.
[0046] Furthermore, the detection mechanism 20 also includes a distance monitoring component 23. The distance monitoring component 23 is installed on the housing 212 and is used to monitor the distance from the inner wall of the pipe 90. The distance monitoring component 23 is communicatively connected to the control unit 80, and the position adjustment mechanism 40 is controllably connected to the control unit 80. When the distance monitoring component 23 detects that the distance from the inner wall of the pipe 90 is small, the control unit 80 controls the position adjustment mechanism 40 to stop running to prevent the detection mechanism 20 from colliding with the inner wall of the pipe 90.
[0047] In one example, the distance monitoring component 23 is implemented as a distance sensor or a proximity sensor.

The advantages of the present invention have been fully and effectively realized.
