AI Technical Summary
The existing technology cannot effectively solve the problems of cleaning, inspection and defect measurement of the sealing surface of the pressure vessel roof of nuclear power plants in a radioactive environment, resulting in large radiation doses, low cleaning efficiency, inaccurate identification of defects, affecting the economic benefits of the power plant.
A seal surface cleaning, inspection and defect measurement device is designed in a radioactive environment, including a walking mechanism, a seal surface cleaning module, a video inspection module and a laser three-dimensional measurement module. It has automatic mode and manual mode, and can walk, position and complete a multi-function integrated design in a narrow space.
It effectively replaces the existing manual operation model, reduces the radiation dose of personnel, improves cleaning efficiency and defect identification accuracy, ensures three-dimensional visual data of the sealing surface quality of the pressure vessel, ensures the integrity of the pressure boundary, and improves the safety and economic benefits of the power plant.
