[0033] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model.

[0034] Example 1

[0035] Referring to Figures 1-2, the positioning components include an arc-shaped positioning plate 3 and an arc-shaped positioning plate 4. The arc-shaped positioning plate 3 has a connecting plate 5 and a connecting plate 6 at its two ends, and the arc-shaped positioning plate 4 has a connecting plate 7 and a connecting plate 8 at its two ends. A hinge plate 9 is provided between the connecting plate 6 and the connecting plate 7, with its two ends hinged to the connecting plate 6 and the connecting plate 7. Connecting components are provided on the connecting plate 5 and the connecting plate 8, which limit the position of the arc-shaped positioning plate 3 and the arc-shaped positioning plate 4 when they are combined.

[0036] The connecting component includes a connecting groove 10 and a threaded rod 11. The connecting plate 5 is provided with a connecting groove 10. One end of the threaded rod 11 is hinged to the connecting plate 8. A positioning knob 13 is threadedly connected to the threaded rod 11.

[0037] In use, place the arc-shaped positioning plate 3 on the natural gas pipeline, flip the arc-shaped positioning plate 4 onto the arc-shaped positioning plate 3, and merge the arc-shaped positioning plate 3 and the arc-shaped positioning plate 4. Flip the threaded rod 11 so that the threaded rod 11 is located in the connecting groove 10 on the connecting plate 5. Rotate the positioning knob 13 so that the positioning knob 13 is in contact with the connecting plate 5, fixing the relative position of the connecting plate 5 and the connecting plate 4, and thus positioning the combined position of the arc-shaped positioning plate 3 and the arc-shaped positioning plate 4.

[0038] Referring to Figure 2, clamping components are provided on the inner surfaces of both the arc-shaped positioning plate 3 and the arc-shaped positioning plate 4.

[0039] The clamping component includes a clamping plate 15 and an elastic guide component. The clamping plate 15 is located inside the arc-shaped positioning plate 3 and the arc-shaped positioning plate 4. The clamping plate 15 is connected to the arc-shaped positioning plate 3 and the arc-shaped positioning plate 4 through the elastic guide component.

[0040] The elastic guiding component includes a guide rod 16 and a spring 17. The clamping plate 15 is symmetrically provided with guide rods 16 on one side facing the arc-shaped positioning plate 3 and the arc-shaped positioning plate 4. The guide rods 16 are slidably connected to the arc-shaped positioning plate 3 and the arc-shaped positioning plate 4. The two ends of the spring 17 are respectively connected to the clamping plate 15 and the arc-shaped positioning plate 3 and the arc-shaped positioning plate 4.

[0041] After the arc-shaped positioning plate 3 and the arc-shaped positioning plate 4 are combined, the clamping plates 15 on the inner side of the arc-shaped positioning plate 3 and the arc-shaped positioning plate 4 move relative to each other under the action of the spring 17, so that they can fit against the surface of natural gas pipelines of different specifications. The guide rod 16 guides the movement direction of the clamping plate 15.

[0042] Referring to Figures 1 and 3, an angle adjustment component is provided on the outer surface of the arc-shaped positioning plate 3. The angle adjustment component includes a positioning seat 18 and a rotating block 19. The positioning seat 18 is disposed on the outer surface of the arc-shaped positioning plate 3. The rotating block 19 is threadedly connected to the end of the positioning seat 18 away from the arc-shaped positioning plate 3. The rotating block 19 is connected to the position adjustment component.

[0043] After the device is positioned on the natural gas pipeline, rotating block 19 is rotated, which drives slide 20 to rotate, thereby adjusting the orientation of controller 1 and probe 2 so that probe 2 can be aimed at the natural gas leak point, improving the accuracy of detection.

[0044] Referring to Figures 1 and 4, a position adjustment component is provided on the end of the angle adjustment component away from the arc-shaped positioning plate 3. The position adjustment component adjusts the position of the controller 1. A probe 2 connected to the controller 1 is provided on the side of the controller 1.

[0045] The position adjustment component includes a slide groove 20, a slider 21, and an adjustment rod 22. The adjustment rod 22 is rotatably connected in the slide groove 20, and the slider 21 is slidably connected in the slide groove 20. The adjustment rod 22 is threadedly connected to the slider 21, and the slider 21 is connected to the controller 1 through a mounting plate 12.

[0046] After the orientation of probe 2 is adjusted, rotate the adjusting rod 22 to drive the slider 21, which is threaded to it, to move within the slide groove 20. The slider 21 drives the controller 1 and probe 2 to move through the mounting plate 12, so that probe 2 is close to the place where natural gas is prone to leak, thereby improving the accuracy of detection. When a natural gas leak is detected, the controller 1 sends an alarm signal to remind the user.

[0047] Example 2

[0048] Referring to Figures 1-2, the connecting plate 5 is provided with a rubber pad 14;

[0049] The inner surface of the clamping plate 15 is uniformly provided with anti-slip stripes, and the spring 17 is sleeved on the outside of the guide rod 16.

[0050] Based on Embodiment 1, when the positioning knob 13 is rotated, the positioning knob 13 is made to fit against the rubber pad 14 on the connecting plate 5, so as to avoid the positioning knob 13 from shifting its position and thus ensure the connection effect of the connecting parts.

[0051] The anti-slip stripes on the inner surface of the clamping plate 15 ensure the clamping effect of the clamping plate 15 on the natural gas pipeline. The guide rod 16 guides the extension and retraction direction of the spring 17 sleeved on it.

[0052] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
