[0002] Boiler pipes in power plants are generally welded from seamless steel pipes or welded steel pipes. Since boiler pipes in power plants work under high temperature and high pressure for a long time, whether there is damage in the boiler pipes is very important for the safe operation of the boiler pipes in power plants. Flexible phased array probes have outstanding advantages in non-destructive testing of objects with curved surfaces such as boiler pipes in power plants. However, the existing flexible phased array probes need to be pressed by hand when in use, so that the probe body of the flexible phased array probe fits tightly with the surface of the boiler pipe in the power plant. However, the temperature of some boiler pipes in power plants is relatively high, and it is easy to get burned when pressing the flexible phased array probe by hand.

[0003] Moreover, the dust attached to the surface of the power plant boiler pipe will affect the detection of the flexible phased array probe. Before the detection, the surface of the power plant boiler pipe to be detected needs to be wiped. Utility Model Content
