Problems solved by technology

At present, there are similar products at home and abroad, but most of them seal the rotating head part in a container with transparent glass in front, and then statically seal the output control cable with the container to achieve the purpose of dynamic observation through static sealing. The disadvantage is that the area of ​​the transparent glass cannot be too large to affect its observation range

Description

Technical field [0001] The invention relates to a camera system mainly used for long-distance observation of an underwater area with strong radioactivity, so as to realize the control of the underwater operation process of a nuclear power plant. Background technique [0002] In nuclear power plants, there are many areas with strong radiation, and some maintenance and operation processes need to be observed remotely through a thick water protection layer. The extensive use of underwater camera systems can ensure the safety of maintenance and operators. The key technology of the underwater camera system lies in the dynamic sealing of the horizontal and vertical two rotating shafts. At present, there are similar products at home and abroad, but most of them seal the rotating head part in a container with transparent glass in front, and then statically seal the output control cable with the container to achieve the purpose of dynamic observation through static sealing. Its dis...
