[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figures 1-4 ,

[0034] First embodiment:

[0035] The utility model provides a technical solution: a natural gas pipeline leakage detection device, including a detector body 1, a hose 2 is provided on the back of the detector body 1, a collar 3 is provided on the outer shell of the hose 2, and an arc-shaped detection plate 4 is connected to one side of the collar 3. By setting the arc-shaped detection plate 4, the collar 3 can be fitted to the pipeline, and a sealed cavity is provided inside to prevent gas leakage; a fixing component 5 for fixing to the outside of the pipeline is provided outside the collar 3, a moving component 6 is connected to the outside of the fixing component 5, and a marking component 7 for marking a leak outside the pipeline is provided inside the moving component 6.

[0036] Specifically, such as Figure 2-3 As shown, the fixing component 5 includes a frame 51, a ring 3 is connected to the frame 51, and a slide rod 52 is slidably connected to the frame 51. By setting the frame 51 and the slide rod 52, the frame 51 cooperates with the slide rod 52 to realize that the frame 51 limits the slide rod 52 to prevent the slide rod 52 from shaking when sliding; a pull plate 53 is connected to the slide rod 52, and a rubber block 54 is connected to the bottom of the slide rod 52. By setting the rubber block 54, the pipeline can be fixed without slipping; a return spring 55 is provided on the outer sleeve of the slide rod 52. By setting the return spring 55, when the pull plate 53 is released, the return spring 55 applies elastic force to the pull plate 53 to quickly reset it; one end of the return spring 55 is connected to the bottom of the pull plate 53, and the other end of the return spring 55 is connected to the frame 51. An anti-slip pad is provided in the frame 51, and the position of the anti-slip pad corresponds to the rubber block 54.

[0037] During operation, the pull plate 53 is pulled and the frame 51 is then placed outside the pipe. The pull plate 53 is then released. At this time, the return spring 55 applies elastic force to the pull plate 53, and the elastic force drives the pull plate 53 to move. The pull plate 53 drives the slide bar 52 to slide in the frame 51, and then drives the rubber block 54 to fit the outer wall of the pipe. At this time, the pipe can be inspected. If the position needs to be changed, the pull plate 53 is pulled and then the frame 51 is pushed to slide outside the pipe. In this way, the arc-shaped detection plate 4 can be more firmly attached to the outside of the pipe during detection, avoiding the problem of inaccurate detection results.

[0038] Second embodiment:

[0039] Specifically, such as Figure 4 As shown, the movable part 6 includes two movable plates 61, and the front of the movable plate 61 is connected to a handle 62, and two slide grooves 63 are provided in the movable plate 61, and sliders 64 are slidably connected in the two slide grooves 63. By setting the sliders 64 and the slide grooves 63, the sliders 64 cooperate with the slide grooves 63 to achieve the limit of the slide grooves 63 on the sliders 64, to prevent the sliders 64 from shaking when sliding; the sliders 64 are connected to the outside of the frame 51, and one side of the two movable plates 61 is connected to the same shell 65, the shell 65 is slightly larger than the arc detection plate 4, and is sleeved on the outside of the arc detection plate 4, and the marking part 7 includes a sponge 71. By setting the sponge 71, the sponge 71 can absorb paint and mark the leaking place; the sponge 71 is stuck in the shell 65, and the front and back of the shell 65 are provided with feed ports 72, and the feed port 72 is provided with a feed port 73. The shape of the sponge 71 is consistent with the internal shape of the shell 65, and its length is slightly longer than the shell 65.

[0040] By observing the detector body 1, when a leak is detected, the handle 62 is pushed, and the handle 62 drives the movable plate 61 to slide outside the slider 64 through the slide groove 63, and then the movable plate 61 drives the shell 65 to move, and the shell 65 drives the sponge 71 to move synchronously. At this time, the sponge 71 full of paint is attached to the outside of the pipe, and the paint can mark the outside of the pipe. When paint needs to be added, the paint is poured into the feed port 72, and then enters the sponge 71 from the feed port 73. At this time, the sponge 71 can absorb the paint, thereby achieving accurate marking of the leak in the pipe.

[0041] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
