[0027] At present, the traditional method of detecting the inner wall circumferential weld of large pipelines mainly relies on manual visual inspection or simple automated equipment. Manual visual inspection usually takes a lot of time to check the welds one by one, which is inefficient. The fatigue and experience differences of the inspectors may lead to inconsistent judgments on weld defects, affecting the reliability of the inspection results. For non-large pipelines that cannot be entered by humans, since the human eye cannot observe the appearance of the pipeline, automated inspection methods are urgently needed.
[0028] In view of this, if Figure 1 and Figure 2 As shown, the utility model proposes a pipeline inner wall weld detection component 1000, comprising: a motion component 1 and a detection component 2. The motion component 1 is used to be placed in the pipeline and can be movably arranged along the extension direction of the pipeline; the detection component 2 includes a mounting plate 21, a camera 22 and a driving device 23, the mounting plate 21 can be rotatably mounted on the motion component 1, the camera 22 is mounted on the mounting plate 21, and the driving device 23 is used to drive the mounting plate 21 to rotate, so as to drive the camera 22 to rotate circumferentially around the inner wall of the pipeline, and the camera 22 is used to obtain an image of the inner wall of the pipeline.
[0029] It should be noted that, in the technical solution of the present utility model, the driving device 23 can be a motor or a cylinder, which is not limited here, as long as it can drive the mounting plate 21 to rotate.
[0030] The technical solution of the utility model adopts the driving device 23 to drive the mounting plate 21 to rotate, so as to drive the camera 22 to rotate circumferentially around the inner wall of the pipe, so that when the camera 22 identifies the weld on the inner wall of the pipe, it can rotate one circle driven by the driving device 23, thereby recording the shape of the weld on the entire inner wall of the pipe, thereby improving the degree of automation of the pipe inner wall weld detection component 1000 and reducing the difficulty of detecting the shape of the pipe inner wall weld.
[0031] In one embodiment, a movable member 24 movable along the radial direction of the mounting plate 21 is mounted on the mounting plate 21 , and the camera 22 is mounted on the movable member 24 , so that the camera 22 can approach or move away from the inner wall of the pipe.
[0032] The technical solution of the utility model can drive the camera 22 to approach or move away from the inner wall of the pipeline by adopting the movable part 24 to adjust the distance between the camera 22 and the inner wall of the pipeline, so that the spacing between the camera 22 and the inner wall of the pipeline is consistent with the focal length of the camera 22, thereby improving the clarity of the picture taken by the camera 22 and facilitating the identification of the shape of the weld on the inner wall of the pipeline.
[0033] In one embodiment, the mounting plate 21 is further provided with a track 25 extending along the radial direction thereof, and the movable member 24 is movably disposed on the track 25 .
[0034] The technical solution of the utility model adopts the track 25 so that the movable member 24 can move along the radial direction on the track 25, thereby adjusting the distance between the camera 22 and the inner wall of the pipe to adapt the focal length of the camera 22 and improve the picture clarity.
[0035] In addition, in one embodiment of the utility model, a motor is provided on the track 25, and the motor drives the movable part 24 to be close to or away from the inner wall of the pipe through a ball screw, so as to achieve precise adjustment of the distance between the camera 22 and the inner wall of the pipe, thereby improving the clarity of the picture taken by the camera 22.
[0036] In one embodiment, a light source 26 is disposed at the end of the track 25 .
[0037] The technical solution of the utility model can illuminate the weld on the inner wall of the pipeline by adopting the light source 26, so that the camera 22 can identify the weld on the inner wall of the pipeline. When the driving device 23 drives the mounting plate 21 to rotate, the light source 26 can rotate together with the track 25 to ensure that the light source 26 exists in the shooting area of the camera 22, so that the actual situation of the weld on the inner wall of the pipeline can be clearly and intuitively recorded.
[0038] In one implementation, the driving device 23 includes a stepping motor 231 .
[0039] The technical solution of the utility model adopts a stepper motor 231 as the driving device 23. The stepper motor 231 has high positioning accuracy, so the rotation accuracy of the mounting plate 21 can be improved, thereby ensuring that the camera 22 can accurately identify the condition of the entire circle of the weld on the inner wall of the pipeline, thereby improving the accuracy of weld inspection.
[0040] In one embodiment, the motion component 1 includes a main body 11 and a driving component 12 , the detection component 2 is installed on the main body 11 , and the driving component 12 is used to drive the main body 11 to move along the extension direction of the pipeline.
[0041] The technical solution of the utility model uses the driving component 12 to drive the main body 11 to move along the extension direction of the pipeline, so as to drive the detection component 2 to move along the extension direction of the pipeline, thereby continuously identifying and recording the welds on the inner wall of the pipeline.
[0042] In one embodiment, the driving assembly 12 includes a driving wheel set 121, and the driving wheel set 121 is used to support the main body 11 and drive the main body 11 to move along the extension direction of the pipeline.
[0043] The technical solution of the utility model uses the driving wheel group 121 to support the main body 11, thereby improving the stability of the main body 11, thereby improving the stability of the camera 22, reducing the shaking of the camera 22, so as to improve the image clarity of the weld on the inner wall of the pipeline taken by the camera 22.
[0044] In one embodiment, a plurality of driving wheel sets 121 are provided and are arranged around the main body 11 .
[0045] The technical solution of the utility model further improves the stability of the main body 11 by adopting multiple driving wheel groups 121 and surrounding them on the main body 11, and can ensure that the distance between the central axis of the main body 11 and the inner wall of the pipe is consistent at all angles, thereby further improving the image clarity of the weld on the inner wall of the pipe taken by the camera 22.
[0046] In one embodiment, the driving wheel assembly 121 includes a support frame 1211 installed on the main body 11 and a driving wheel 1212 installed on the support frame 1211. The support frame 1211 is adjustable to adjust the distance between the main body 11 and the inner wall of the pipe.
[0047] It should be noted that the driving wheel 1212 can be driven by electricity or mechanical energy, which is not limited here.
[0048] The technical solution of the utility model can adjust the distance between the main body 11 and the inner wall of the pipeline by adopting the support frame 1211, so that the pipeline inner wall weld detection component 1000 can adapt to pipelines with different diameters, thereby improving the application range of the pipeline inner wall weld detection component 1000.
[0049] In one embodiment, the support frame 1211 includes two support arms 1211a, which are installed on the main body 11. The two support arms 1211a are arranged at intervals along the extension direction of the pipeline. The two support arms 1211a are arranged at a certain angle. An elastic traction member 1213 is arranged between the two support arms 1211a to adjust the angle between the two support arms 1211a.
[0050] The technical solution of the utility model can passively adjust the distance between the main body 11 and the inner wall of the pipe by adjusting the angle between the two support arms 1211a through the use of an elastic traction member 1213. When a plurality of driving wheel groups 121 are provided, the distance between the main body 11 and the inner wall of the pipe at each angle is consistent, so that during the rotation of the mounting plate 21, the distance between the camera 22 and the weld on the inner wall of the pipe is kept consistent, thereby improving the image clarity of the weld on the inner wall of the pipe taken by the camera 22.
[0051] Specifically, in one embodiment of the utility model, the elastic traction member 1213 includes a spring 1213a; there are multiple driving wheel groups 121, among which only one driving wheel group 121 is provided with a power source, and the driving wheels 1212 in the other driving wheel groups 121 are not provided with a power source, and therefore only have a supporting function to reduce energy consumption.
[0052] In addition, in one embodiment of the utility model, the pipeline inner wall weld detection component 1000 is electrically connected to a PC, so that the drive device 23 and the camera 22 in the pipeline inner wall weld detection component 1000 can complete image acquisition and image data processing under the instructions output by the PC; under the regulation of the PC instructions, the motion component 1 can move in the pipeline along the extension direction of the pipeline. When the camera 22 recognizes the weld on the inner wall of the pipeline, the PC outputs an instruction to the motion component 1 to stop the movement of the motion component 1, and at the same time, the drive device 23 drives the mounting plate 21 to rotate, so that the camera 22 can circle around the extension direction of the pipeline as the axis, thereby recording the shape of the pipeline inner wall weld. After recording, the PC outputs an instruction to the motion component 1 so that the motion component 1 continues to move, so as to realize continuous identification and recording of the pipeline inner wall weld, thereby improving the automation degree of the pipeline inner wall weld detection component 1000.
