[0027] 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.

[0028] Reference Figure 1-3, the utility model provides an embodiment: a natural gas detection device, including a support platform 1, one side of the outer wall of the support platform 1 is fixedly connected to one end of two telescopic plates 2, the other ends of the two telescopic plates 2 are fixedly connected to the same fixed ring 3, one side of the outer wall of the fixed ring 3 is rotatably connected to a gear frame 6, one side of the outer wall of the gear frame 6 is fixedly connected to a connecting rod 4, one side of the outer wall of the support platform 1 is fixedly connected to a telescopic rod 2 12, the top of the telescopic rod 2 12 is fixedly connected to a micro motor 5, the output end of the micro motor 5 is fixedly connected to the outer wall of the connecting rod 4, the other side of the outer wall of the fixed ring 3 is fixedly connected to a fixed frame 7 and a fixed frame 10, the interior of the fixed frame 7 is slidably connected to a rack 8, one end of the fixed frame 10 is rotatably connected to a driven gear 9, one side of the outer wall of the micro motor 5 is provided with a synchronous cleaning mechanism 11, and the bottom of the support platform 1 is fixedly connected to a moving component;

[0029] Specifically, the micro motor 5 is the power source of the entire transmission system. When the micro motor 5 is started, the power output thereof will drive the gear rack 6 to start rotating, thereby inducing relative rotation between the gear rack 6 and the fixed ring 3. The rotation of the gear rack 6 will also drive the driven gear 9 to rotate. The driven gear 9 is passively rotated by the rotation of the gear rack 6. When the driven gear 9 rotates, it transmits the torque to the rack 8 through meshing transmission. The rack 8 reciprocates along the tangent perpendicular to the fixed ring 3. The movement of the rack 8 will drive multiple slides 13 to change their distance. The slide 13 is a key component supporting the inside of the natural gas pipeline. The change in the distance between them directly determines the diameter range of the natural gas pipeline that can be clamped. When the rack 8 moves, it will push the slide 13 to move inward or outward, thereby achieving the clamping of natural gas pipelines of different diameters.

[0030] The synchronous cleaning mechanism 11 includes a fixed plate 1101, which is fixedly connected to the output end of the other side of the micro motor 5. Both ends of the fixed plate 1101 are slidably connected to the extension plate 1103. A slot 1106 is provided on one side of the outer wall of the extension plate 1103. One end of a telescopic rod 1105 is provided inside the slot 1106. The other end of the telescopic rod 1105 is fixedly connected to one side of the outer wall of the rack 8. Cleaning sand 1104 is fixedly connected to one side of the outer wall of the extension plate 1103.

[0031] Specifically, the distance between the two telescopic rods 1105 changes with the movement of the two racks 8, and since the telescopic rod 1105 is fixed at one end of the rack 8, when the rack 8 slides inward and outward of the gear rack 6, it drives the telescopic rod 1105 to slide synchronously, and the telescopic rod 1105 drives the extension plate 1103 to slide synchronously, so that the cleaning sand 1104 at both ends of the extension plate 1103 contacts the inner wall of the natural gas pipeline, and the micro motor 5 starts to drive the extension plate 1103 to rotate, thereby completing the cleaning of the inner wall of the natural gas pipeline by the cleaning sand 1104.

[0032] The driven gear 9 is meshed and connected with the gear frame 6 and the rack 8 respectively;

[0033] One end of the rack 8 is fixedly connected to a slide 13;

[0034] Specifically, the rotation of the gear rack 6 drives the driven gear 9 to rotate, and the driven gear 9 drives the rack 8 to slide through meshing transmission, thereby completing the support and fixation of the slide 13 on the inner wall of the natural gas pipeline.

[0035] A limiting groove 1102 is formed inside the extension plate 1103;

[0036] The interior of the fixing plate 1101 is fixedly connected with a convex block 1107;

[0037] Specifically, the convex block 1107 slides inside the limiting groove 1102 so that the telescopic distance of the extension plate 1103 is limited, thereby preventing the extension plate 1103 from falling off.

[0038] The moving assembly includes a second slide 14, and the two second slides 14 are fixedly connected to the two ends of the bottom of the outer wall of the support platform 1, and a micro motor 15 is arranged on the outer wall of one side of the second slide 14;

[0039] Specifically, the micro motor 15 is started to drive the second slide 14 at one end to rotate, thereby driving the movement of the entire device to facilitate the detection of the interior of a natural gas pipeline over a long distance.

[0040] Working principle: The micro motor 5 is the power source of the entire transmission system. When the micro motor 5 is started, the power it outputs will drive the gear rack 6 to start rotating, thereby causing the gear rack 6 to rotate relative to the fixed ring 3. The rotation of the gear rack 6 will also drive the driven gear 9 to rotate. The driven gear 9 is passively rotated by the rotation of the gear rack 6. When the driven gear 9 rotates, it transmits the torque to the rack 8 through meshing transmission. The rack 8 reciprocates along the tangent perpendicular to the fixed ring 3. The movement of the rack 8 will drive multiple slides 13 to change their distance. The slide 13 is a key component supporting the inside of the natural gas pipeline. The change in the distance between them directly determines the diameter range of the natural gas pipeline that can be clamped. When the rack 8 moves, it will push The movable slide 13 moves inward or outward to clamp natural gas pipelines of different diameters. The spacing between the two telescopic rods 1105 changes with the movement of the two racks 8. Since the telescopic rod 1105 is fixed at one end of the rack 8, the rack 8 drives the telescopic rod 1105 to slide synchronously when sliding inward and outward of the gear frame 6. The telescopic rod 1105 drives the extension plate 1103 to slide synchronously, so that the cleaning sand 1104 at both ends of the extension plate 1103 contacts the inner wall of the natural gas pipeline. The micro motor 5 starts to drive the extension plate 1103 to rotate, completing the cleaning of the inner wall of the natural gas pipeline by the cleaning sand 1104. The micro motor 15 starts to drive the slide 14 at one end to rotate, driving the movement of the entire device to facilitate the detection of the inside of the natural gas pipeline over a longer distance.

[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.
