[0002] The pipeline inner wall coating thickness detection device is an important tool to ensure the quality of pipeline coating, provide adequate protection and optimize cost control. It usually adopts magnetic induction effect, ultrasonic measurement, etc. Among them, the magnetic induction coating thickness gauge is a common type. Its working principle is to use the magnetic induction effect to measure the thickness of the coating through the action of the magnetic field.

[0003] Existing thickness gauges can only measure the ends of pipes through induction probes and cannot measure the deeper inner walls of pipes. Moreover, when the thickness of the inner walls of pipes is inconsistent, they cannot adapt to changes, resulting in inaccurate measurements or failure to complete the measurement task, reducing detection efficiency and affecting detection results. It has limitations.

[0004] The reason for this problem is that the existing induction probe cannot adjust its length, resulting in a blind spot when detecting the inner wall of the pipe. In actual use, the measured thickness of the inner wall of the pipe will be inconsistent. Since the induction probe needs to be against the pipe wall, it cannot measure some narrow pipes and has limitations. Therefore, we propose a pipeline inner wall coating thickness detection device to solve the above problem. Utility Model Content
