[0034] Working principle: When in use, first place the driving structure 1 on the top of the pipeline to be inspected, and make the bottom of the driving wheel 207 fit the top outer surface of the pipeline, and press down the clamping plate 102 so that it can be turned down through the first movable rod 101, so that the clamping plate 102 wraps the outer surface of the pipeline, and the two clamping plates 102 are fixed by bolts 103, and when the clamping plate 102 is turned down, the inner surface of the scraper 116 will first fit the outer surface of the pipeline, and when the clamping plate 102 wraps the outer surface of the pipeline, it will drive the outer surface of the pipeline through pressure. The telescopic column 114 and the return spring 115 on the flange 113 are contracted, so that the scraper 116 can firmly fit the outer surface of the pipe, and the cleaning liquid is injected into the water tank 111 through the water injection pipe 112. Then, the pump 109 is started through the power supply system of the pump 109, so that when it is running, the cleaning liquid in the water tank 111 is pumped into the pump 109 through the second water inlet pipe 110, and is transported by the pump 109, so that the cleaning liquid enters the hose 107 through the first water inlet pipe 108, and then is discharged from the hose 107. 107 is used for dispersion, so that the cleaning liquid enters the interior of the nozzle 106 through the conveying frame 105 on the connecting column 104, and the nozzle 106 sprays the cleaning liquid to wash the outer surface of the pipeline. When the nozzle 106 is cleaning the pipeline, the device can be driven to move through the driving structure 1, so that the scraper 116 scrapes the outer surface of the pipeline after washing. At the same time, the driving system of the detection device body 117 is used to start the detection device body 117, so that the device can synchronously inspect the pipeline when moving, and the pump can be used to clean the pipeline. The structures such as 109 and the scraper 116 not only enable the device to automatically flush the pipeline when inspecting the pipeline, reducing the steps of manual cleaning, but also ensure that the cleaning liquid fully covers and flushes the outer surface of the pipeline. The scraper 116 can scrape off the dirt and impurities on the pipeline when moving to ensure that the pipeline surface is clean. Through the driving structure 1 and the detection device body 117, non-destructive testing of the pipeline can be performed immediately after the pipeline cleaning is completed, which can ensure that the pipeline surface is clean and there will be no impurities interfering with the detection results, thereby improving the accuracy of the detection.During use, when the splint 102 wraps around the pipe, the inner surface of the moving wheel 201 on the support column 2 will be synchronously attached to the outer surface of the pipe, and then the motor 202 will be started through the power supply system of the motor 202, so that when it is running, it can drive the first pulley 204 to rotate. When the first pulley 204 is rotating, it can be transmitted to the second pulley 205 through the belt body 206, so that the second movable rod 203 rotates synchronously, and then the second movable rod 203 is transmitted to the driving wheel 207, so that it rotates on the outer surface of the pipe, and then the left driving wheel 207 and the moving wheel 201 are pulled to rotate, so that the device moves on the outer surface of the pipe, and through the structure of the motor 202 and the driving wheel 207, the device can automatically move on the outer surface of the pipe, which can reduce the burden on the operator, improve work efficiency, and realize the cleaning and inspection of long-distance pipes, avoiding the difficulties and risks of manual operation.
