Description

Technical Field

[0001] The utility model relates to the technical field of natural gas pipeline detection devices, in particular to a comprehensive inspection device for natural gas stations. Background Art

[0002] Natural gas pipelines are facilities used to transport natural gas, meeting people's energy needs. Natural gas is a clean fuel that reduces environmental pollution. Compared to traditional fossil fuels, its use reduces emissions of greenhouse gases such as carbon dioxide, helping to mitigate global warming. However, natural gas pipelines are partially exposed to the elements. Prolonged exposure to the elements, such as wind, sun, and low temperatures, can damage pipelines, leading to natural gas leaks. Leaked natural gas not only impacts the environment but can also cause combustion and explosions if exposed to fire. Therefore, regular inspections of natural gas pipelines are necessary. Traditionally, these inspections rely on instruments to measure the natural gas content in the air outside the pipeline to determine if the pipeline is damaged.

[0003] Chinese patent CN218993005U discloses a comprehensive intelligent inspection device for natural gas stations. This device detects leaks in gas pipelines by providing an air inlet nozzle that does not contact the gas pipeline. However, the air inlet nozzle does not seal the pipeline and can only detect one side of the pipeline. When the crack at the outer end of the pipeline is small, less natural gas leaks out, and less enters the detection instrument. This reduces the accuracy of the detector in natural gas detection, making it difficult to accurately determine whether the outer end of the pipeline is damaged.

[0004] To this end, the utility model provides a comprehensive inspection device for a natural gas station, which seals the pipeline through two sets of clamping rings and sealing rings at the outer ends thereof to solve the above-mentioned problem. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the 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.

[0021] Example 1:

[0022] See also Figure 1-3 A comprehensive inspection device for a natural gas station comprises a splint 1, with support rods 2 symmetrically and slidingly connected on both sides of the splint 1, a clamping ring 3 fixedly connected to the inner side of the support rod 2, a support spring 4 fixedly connected between the splint 1 and the support rod 2, a side plate 5 symmetrically and fixedly connected to the outer end of the clamping ring 3, a rotating rod 6 rotatably connected to the inner side of the side plate 5, a torsion spring fixedly connected between the side plate 5 and the rotating rod 6, a guide wheel 7 rotatably connected to the top end of the rotating rod 6, a sealing ring 8 symmetrically and fixedly connected to both sides of the clamping ring 3, an air intake pipe 9 fixedly connected to the outer end of the clamping ring 3 and connected, and the air intake pipe 9 passes through the splint 1. The purpose of this setting is that when inspecting the natural gas pipeline, the two sets of clamping rings 3 are first clamped to the outer end of the natural gas pipeline. The elastic force generated by the support spring 4 enhances the stability of the two sets of clamping rings 3 clamping the natural gas pipeline. In the process of the two sets of clamping rings 3 clamping the natural gas pipeline, the elastic force generated by the torsion spring causes the rotating rod 6 and the guide wheel 7 at the outer end to resist the natural gas pipeline, so that the natural gas pipeline inside the clamping ring 3 is in the center position. At the same time, the sealing ring 8 is used to seal the natural gas pipeline, thereby enhancing the sealing of the two sets of clamping rings 3 on the natural gas pipeline. By sealing, the influence of the external environment on the detection accuracy is reduced.

[0023] Preferably, the clamping ring 3 and the sealing ring 8 are both semicircular, the two sets of rotating rods 6 are arranged in a cross shape, and one end of the air inlet pipe 9 is fixedly connected to the conduit 10. The purpose of this arrangement is that the air inlet pipe 9 and the conduit 10 are used to transport the gas between the two sets of clamping rings 3 and the natural gas pipeline to the detector 11.

[0024] Preferably, a detector 11 is fixedly connected to the tail end of the conduit 10, and a display 12 is fixedly connected to the outer end of the detector 11. The detector 11 and the display 12 are electrically connected. The purpose of this arrangement is that the detector 11 is used to detect the gas between the two sets of clamping rings 3 and the natural gas pipeline, and the detection results are displayed on the display 12, so that the inspection personnel can quickly detect whether there is a leak in the natural gas pipeline.

[0025] Example 2:

[0026] See also Figure 1-4 This embodiment, based on the first embodiment, provides a technical solution for a comprehensive inspection device for natural gas stations: the outer end of the clamping plate 1 is fixedly connected to a connecting plate 13, which is internally rotatably connected to a connecting column 14. The bottom end of the connecting column 14 is fixedly connected to a telescopic rod 15, and the outer end of the telescopic rod 15 is slidably connected to a sleeve rod 16. This arrangement facilitates the rotation of the telescopic rod 15 inside the connecting plate 13 when inspecting high-altitude natural gas pipelines. Furthermore, the telescopic rod 15 can be raised and lowered within the sleeve rod 16, thereby adjusting the height of the clamping plate 1.

[0027] Preferably, the bottom end of the sleeve rod 16 is rotatably connected to a handle 17, and the top end of the handle 17 is fixedly connected to a screw rod 18. The screw rod 18 is rotatably connected to the interior of the sleeve rod 16 and is threadedly connected to the telescopic rod 15. The purpose of this arrangement is that when adjusting the length of the telescopic rod 15 and the sleeve rod 16, the handle 17 is rotated, and the handle 17 drives the screw rod 18 to rotate inside the sleeve rod 16. Due to the threaded connection between the screw rod 18 and the telescopic rod 15, the telescopic rod 15 slides inside the sleeve rod 16, thereby extending the telescopic rod 15.

[0028] Preferably, a clip 19 is clamped on the outer end of the sleeve rod 16, and the catheter 10 is clamped inside the clip 19. The purpose of this arrangement is that the clip 19 can clamp the catheter 10 to prevent the catheter 10 from being entangled with the telescopic rod 15 and the sleeve rod 16 during the detection process, thereby affecting the detection effect.
