[0027] It should be noted that some common pipeline inner diameter measuring devices cannot effectively help workers measure and check the inner diameters at different locations in the pipeline, and their use is relatively limited;

[0028] In this embodiment, when measuring the inner diameter of the pipeline, the entire device is placed in the pipeline, and a controller (a controller is provided on the device, and remote control can be performed at the same time, which is a prior art and will not be described in detail here) is used to start multiple telescopic rods 6 to drive multiple walking wheels 8 to contact the inner wall of the pipeline respectively. When measuring the pipeline, the distance sensor 3 is started by the controller to measure the distance to the top of the pipeline, and the data is recorded after the measurement is completed. Then, the controller is used to start the rotating mechanism 4 to drive the distance sensor 3 to rotate 180 degrees, and then the distance between the distance sensor 3 and the bottom of the pipeline is measured. The two data are added, and then the length of the mounting block 2 and the two distance sensors 3 is added to obtain the inner diameter length of the pipeline.

[0029] When it is necessary to inspect the inner diameters at different positions inside the pipeline, the driving mechanism is started by the control valuer to drive the walking wheel 8 to move, thereby driving the entire device to move inside the pipeline. Similarly, the inner diameters at different positions inside the pipeline are measured according to the above steps. Through the data difference of the inner diameters at different positions, the corrosion situation in the pipeline can be checked and understood. At the same time, when the entire device moves on the pipeline, the camera 5 can check the situation inside the pipeline, so as to facilitate the staff to understand the situation inside the pipeline. The entire measurement process can measure the inner diameters at different positions inside the pipeline, so that the staff can better understand the corrosion and usage situation inside the pipeline, and better meet the actual measurement and detection needs of the pipeline.

[0037] In this embodiment, when the mounting frame 1 drives the camera 5 to move in the pipeline, when impurities in the pipeline fall onto the transparent protective cover 12, in order to avoid affecting the monitoring angle of the camera 5, the power motor 15 is started by the controller to drive the placement shaft 13 to rotate, thereby driving the cleaning frame 14 to rotate back and forth to clean the impurities adhered to the transparent protective cover 12, thereby avoiding affecting the monitoring angle of the camera 5 and improving the monitoring effect of the camera 5.
