Intelligent ultrasonic online thickness measurement and corrosion state evaluation device and method

The invention discloses an intelligent ultrasonic online thickness measurement and corrosion state evaluation device. The device comprises a control panel, a cleaning machine driving module, an ultrasonic thickness measuring module, a position detecting module, a servo mechanism driving module and a coupling agent spraying executing mechanism module. The position detecting module is used for detecting a measuring point part and sending the position of a thickness measuring point to the control panel through an encoder. The coupling agent spraying execution mechanism module is used for sprayinga coupling agent to a to-be-measured thickness area. The ultrasonic thickness measuring module is used for measuring the thickness regularly. The cleaning machine driving module is used for cleaninga high-temperature ultrasonic probe of the ultrasonic thickness measurement module after thickness measurement. The control panel is used for analyzing and logically operating the data measured by theultrasonic thickness measu
