[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-5 , the utility model provides an embodiment: a natural gas pipeline weld detection device, including a support frame 1, the front and rear ends of one side of the outer wall of the support frame 1 are fixedly connected with a connecting block 2, the two connecting blocks 2 are internally rotatably connected with a rotating rod 4, one side of the outer wall of the front connecting block 2 is fixedly connected with a micro motor 3, the output end of the micro motor 3 is connected to the rotating rod 4, one side of the outer wall of the rotating rod 4 is fixedly connected with one end of a connecting plate 5, the other end of the connecting plate 5 is fixedly connected with a C-shaped frame 6, and the other side of the outer wall of the support frame 1 is provided with a cleaning mechanism 9;

[0030] Specifically, the core part of the device is the support frame 1, which provides a solid foundation for the entire detection device. The front and rear ends of the outer wall of the support frame 1 are fixedly connected with connecting blocks 2. The two connecting blocks 2 are used to support and rotate the rotating rod 4. The rotation of the rotating rod 4 is realized by a micro motor 3. The output end of the micro motor 3 is connected to the rotating rod 4, providing continuous and stable power for the rotating rod 4. The design of the C-frame 6 enables it to fit the weld tightly to ensure the accuracy of the detection result. The rotation of the rotating rod 4 is driven by the micro motor 3, and the connecting plate 5 and the C-frame 6 can move along the weld to achieve comprehensive weld detection. In addition, a cleaning mechanism 9 is provided on the other side of the outer wall of the support frame 1, which is used to remove impurities and dirt on the surface of the weld during the detection process. The design of the cleaning mechanism 9 can be adjusted according to actual needs to ensure the cleanliness of the weld surface and improve the reliability of the detection result. In practical applications, the natural gas pipeline weld detection device can be widely used in natural gas pipeline weld detection of various specifications. By adjusting the size of the C-frame 6 and the speed of the micro motor 3, it can adapt to the requirements of different pipelines and welds. In addition, the device also has the advantages of simple operation and convenient maintenance, which can greatly reduce the detection cost and improve work efficiency.

[0031] The cleaning mechanism 9 includes a containing frame 901, which is fixedly connected to one side of the outer wall of the support frame 1, a micro motor 902 is fixedly connected to the top of the containing frame 901, a slide plate 904 is fixedly connected to the output end of the micro motor 902, and the slide plate 904 is slidably connected to the inside of the containing frame 901, and the top of the connecting rod 905 is fixedly connected to the bottom of the outer wall of the slide plate 904, and the end of the connecting rod 905 is fixedly connected to a cleaning brush 906;

[0032] A plurality of transmission tubes 903 are equidistantly provided at the bottom of the outer wall of the containing frame 901;

[0033] The containing frame 901 contains magnetic powder inside;

[0034] A rotating shaft 911 is fixedly connected to one side of the outer wall of the micro motor 902, a rotating plate 910 is rotatably connected to the inner side of the rotating shaft 911, a baffle 909 is fixedly connected to one side of the outer wall of the rotating shaft 911, and a stopper 908 is fixedly connected to the inner wall of the connecting rod 905;

[0035] Specifically, when the micro motor 902 rotates counterclockwise, the rotating shaft 911 gives the rotating plate 910 rotation space, so that the output end of the micro motor 902 only drives the cleaning brush 906 to rotate, thereby completing the cleaning of the surface of the natural gas pipeline weld. After the magnetic powder is spread, the micro motor 3 starts to drive the angle between the support frame 1 and the connecting plate 5 to decrease, so as to increase the height of the cleaning brush 906 and prevent the cleaning brush 906 from continuing to contact the surface of the natural gas pipeline. When the micro motor 902 rotates counterclockwise, with the support of the baffle 909 on the rotating plate 910, the rotating plate 910 drives the stopper 908 to rotate, thereby driving the slide plate 904 to rotate. During the rotation of the slide plate 904, the transmission tube 903 is intermittently opened, and the magnetic powder inside the containing frame 901 intermittently falls to the natural gas pipeline weld, thereby completing the spreading of the magnetic powder.

[0036] The cleaning mechanism 9 further includes a groove 907, which is provided on one side of the inner wall of the containing frame 901;

[0037] Specifically, the groove 907 is provided to prevent the magnetic powder in the containing frame 901 from leaking out from the inner wall of the containing frame 901 .

[0038] A plurality of fixed columns 7 are fixedly connected to the interior of the C-shaped frame 6 at equal intervals, and a roller 8 is rotatably connected to the outer wall of the fixed column 7;

[0039] Specifically, the roller 8 rotates freely on the outer wall of the fixed column 7, thereby realizing the flexible movement of the internal components of the C-type frame 6. The rotation of the roller 8 not only reduces friction and wear, but also, after the C-type frame 6 is clamped on the outer wall of the natural gas pipeline, the detection device can be translated on the outer wall of the pipeline through the rolling of the roller 8, so that the welds at different positions of the pipeline can be detected at one time.

[0040] Working principle: The output end of the micro motor 3 is connected to the rotating rod 4, providing continuous and stable power for the rotating rod 4. The design of the C-shaped frame 6 enables it to fit the weld closely to ensure the accuracy of the detection result. The micro motor 3 drives the rotating rod 4 to rotate, and the connecting plate 5 and the C-shaped frame 6 can move along the weld to achieve comprehensive weld detection. When the micro motor 902 rotates counterclockwise, the rotating shaft 911 gives the rotating plate 910 rotation space, so that the output end of the micro motor 902 only drives the cleaning brush 906 to rotate, completing the surface of the natural gas pipeline weld. Cleaning, after the magnetic powder is spread, the micro motor 3 starts to drive the angle between the support frame 1 and the connecting plate 5 to decrease, so as to increase the height of the cleaning brush 906 and prevent the cleaning brush 906 from continuing to contact the surface of the natural gas pipeline. When the micro motor 902 rotates counterclockwise, with the support of the baffle 909 on the rotating plate 910, the rotating plate 910 drives the block 908 to rotate, thereby driving the slide plate 904 to rotate. During the rotation of the slide plate 904, the transmission tube 903 is intermittently opened, and the magnetic powder inside the containing frame 901 intermittently falls to the weld of the natural gas pipeline, completing the spreading of the magnetic powder.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
