[0026] A guiding mechanism 3 is provided below the base 1, a walking mechanism 5 is provided on one side of the holder 4, a wire pressing mechanism 6 is provided on one side of the guiding mechanism 3, and an adjusting mechanism 7 is provided inside the base 1;

[0027] The guide mechanism 3 includes a fixing seat 31, a connecting screw 32, a wire wheel 33, a limiting plate 34 and a fixing nut 35.

The guiding mechanism 3 and the wire pressing mechanism 6 work together to guide the laying of the optical fiber cable.

[0029] In the above-mentioned implementation scheme, the convenient disassembly, assembly and replacement of the wire wheel 33 can be achieved through the linkage action of the connecting screw 32, the limit plate 34 and the fixing nut 35 of the guide mechanism 3. At the same time, since a wire pressing mechanism 6 is installed at the lower side of the guide mechanism 3, the linkage cooperation of the pressure roller 64 of the wire pressing mechanism 6 and the return spring 65 can prevent the optical fiber from warping during the laying and guiding process.

[0030] See also Figure 1 In this embodiment, the walking mechanism 5 includes a fixed ring 51, a fixed plate 52, a first motor 53 and a transmission roller 54. The fixed plate 52 is fixedly installed inside the fixed ring 51, and the transmission roller 54 is connected to the upper part of the first motor 53.

[0031] Specifically, the fixing ring 51 is fixedly installed with the card holder 4, the fixing plate 52 is located above and below the inside of the fixing ring 51, and the driving roller 54 is movably connected between the fixing plates 52.

[0032] In the above embodiment, the transmission roller 54 can be rotated by the action of the first motor 53 of the walking mechanism 5. Since the transmission roller 54 is in contact with the outer surface of the pipeline, the guiding structure as a whole can move on the surface of the pipeline under the action of the walking mechanism 5, so it is suitable for guiding the laying of optical fiber in long-distance natural gas pipelines.

[0033] Furthermore, the size of the traveling mechanism 5 can be adjusted accordingly according to the size of the pipeline. The specific structure and connection structure of the adjusting mechanism 7 for adjusting the size of the traveling mechanism 5 are described in detail below.

[0034] See also Figure 1 and Figure 4In this embodiment, the adjustment mechanism 7 includes a second motor 71, an adjustment screw 72 and a connecting block 73.

[0035] Specifically, the connection block 73 is fixedly installed above the holder 4 , the connection block 73 is slidably connected to the base 1 , and the second motor 71 is fixedly installed on both side surfaces of the base 1 .

[0036] In the above embodiment, the adjustment screw 72 can be rotated by the second motor 71 of the adjustment mechanism 7, and the rotation of the adjustment screw 72 can enable the connecting block 73 to drive the base 4 to move horizontally. At the same time, the walking mechanism 5 is fixedly installed on the base 4, so the size adjustment of the walking mechanism 5 can be achieved.

[0037] See also Figure 1 and Figure 2 In a preferred embodiment, the fixing seat 31 is fixedly installed with the card seat 4, the connecting screw 32 is located at the four corners of one side surface of the fixing seat 31, the connecting seat 61 is fixedly installed with the fixing seat 31, and the connecting piece 63 is movably connected between the pressure rollers 64.

[0038] In the above embodiment, the connection and fixation between the guide mechanism 3 and the wire pressing mechanism 6 can be realized through the cooperation of the fixed seat 31 and the connecting seat 61, and the guide mechanism 3 and the wire pressing mechanism 6 can be connected and fixed with the clamping seat 4 through the fixed seat 31, so that the continuous walking and guiding of the optical fiber cable can be realized during the movement of the guide structure.

[0039] As for additional explanation, the walking mechanism 5 is fixedly mounted on the card holder 4, the guiding mechanism 3 is fixedly mounted on the card holder 4, the adjusting mechanism 7 is movably connected to the card holder 4, and a battery and a controller are fixedly mounted inside the control box 2. The battery inside the control box 2 can supply power to the electrical components in the device, and the walking speed of the walking mechanism 5 can be controlled by the controller.

[0040] The working principle and use process of the utility model are as follows: the operator places the device on the surface of the pipeline, and starts the second motor 71 to drive the adjusting screw 72 to rotate so that the connecting block 73 drives the holder 4, the fixing ring 51 and the transmission roller 54 to move toward the pipeline, so that the transmission roller 54 is in contact with the pipeline, and then the wire wheel 33 is put on the shaft rod of the fixing seat 31, and the limit plate 34 is passed through the connecting screw 32 and moved to one side of the wire wheel 33, and the limit plate 34 is fixed by using the fixing nut 35. After the optical fiber cable on the wire wheel 33 is pulled out and sent to the bottom of the pressure roller 64, the transmission roller 54 can be driven to rotate by starting the first motor 53, so that the guiding structure as a whole can move on the surface of the pipeline, and the optical fiber cable continues to fall during the walking process, so that the optical fiber laying guide can be realized, and the problem of the optical fiber cable warping during the laying process can be avoided by the wire pressing mechanism 6.
