Description

technical field

[0001] The invention relates to the field of equipment control, in particular to an underwater automatic welding maintenance equipment control device. Background technique

[0002] In recent years, in the maintenance of nuclear power plant reactor pressure vessels, in order to reduce the damage of radiation to maintenance workers, maintenance work with water is often adopted, that is, the pressure vessel is filled with water to shield the gamma rays that are extremely harmful to the human body. . However, underwater maintenance operations put forward higher requirements for technology, and usually require the development of dedicated automated maintenance equipment. At the same time, this kind of maintenance equipment not only needs to meet the requirements of the operation function, but also its volume and motion trajectory must be designed according to the actual working space, and it also needs to have the functions of waterproof and radiation protection,...
