[0016] Second, the present invention fixes the bottom plate at the bottom of the mounting plate that has been erected and installed on the pipeline. The electric stretching rod at the bottom of the bottom plate is used to adjust the height, and displaces the cleaning brush under the second support plate below, so that it can move up and down on the outer surface of the pipeline to clean and maintain it, thereby reducing the frequency of pipeline cleaning by staff.

The slide rail inside the mounting ring is used to adjust the angle of the docking plate, so that the laser light and the camera can be rotated and adjusted with the pipeline as the center. , more flexible, the handle is convenient for staff to move. During use, when the vibration mechanism is running, it will inevitably cause the particles at the wear measuring device body to be shaken apart, which may lead to a decrease in clarity.

The positioning rods 207 on both sides and the internal grooves are staggered and adapted to the opposite positioning rod 207 and groove, and can be easily plugged together to complete the installation. The fixation is convenient but not stable. It is mainly used to align the upper fixing plates 104 after the positioning is completed, so as to facilitate bolt fixation and eliminate the need to spend time on the docking between the fixing plates 104.An observation window 307 is provided on the pipe 102 for performing rough measurement and saving raw data before the wear measuring device body 101 performs measurement. The upward and downward displacement of the cleaning mechanism 2 during cleaning can clean the surface of the observation window 307. The displacement of the cleaning mechanism 2 can also drive the laser light 305 and the camera 306 to move, thereby expanding their working area. The interior of the pipe 102 is illuminated by the laser light 305, and then photographed and saved by the camera 306. The setting of the reflector 304 can re-inject part of the light reflected back by the laser light 305 into the interior of the pipe 102, thereby enhancing the clarity as much as possible. The slide rail inside the mounting ring 301 is used to adjust the angle of the docking plate 302, so that the laser light 305 and the camera 306 can be positioned along the pipe 102. 102 is the center for rotation adjustment, which is more flexible, and the handle 303 is convenient for the staff to move. During use, when the vibration mechanism 1 is in operation, it is inevitable that the particles at the wear measuring device body 101 will be shaken apart, which may cause a decrease in clarity. Therefore, the original image of the particles before being shaken apart can be read through the camera that shoots and records at the bottom, which is more accurate and complete in providing data, and is linked with the other two mechanisms. Among them, the camera 306 and the laser light 305 are existing technologies. Through an external power supply, the camera 306 and the computing device have signal transmission to upload and store the image. The laser light 305 uses a 2W full-color animation laser light, and the camera 306 uses the Xiaomi Smart Camera 2 gimbal version.
