Containment camber line water film coverage rate inspection device

The invention discloses a containment camber line water film coverage rate inspection device, and relates to the technical field of nuclear reactor operation and maintenance. The device comprises a detection module, a control module and a calculation module, the detection module is arranged on the outer wall of the containment and moves up and down, the control module sends a control signal to the detection module, and the detection module transmits the detection condition to the control module; and the control module transmits the data to the calculation module to calculate the water film coverage rate. The detection module comprises a wall-climbing robot, the wall-climbing robot comprises a driving part and a detection part, the driving part realizes displacement of the wall-climbing robot through a track, and a magnetic adjusting block is arranged on the inner edge of the track; a magnetic block is also arranged on one side, opposite to the containment wall, of the wall-climbing robot chassis; the detectio
