Abstract

The invention belongs to the technical field of nuclear power station equipment or part nondestructive test and use and relates to a vector control underwater planktonic video inspection device. The device comprises a shore control system, an umbilical cable folding and unfolding device, an umbilical cable, a submersible main body and an underwater control system. The underwater control system is installed in the submersible main body. The submersible main body is connected to the shore control system through the umbilical cable. The umbilical cable folding and unfolding device realizes folding and unfolding of the umbilical cable. The submersible main body comprises a floating block, a power platform and an underwater high definition shooting assembly. The elliptical floating block is installed at the upper part of the power platform. The underwater high definition camera assembly is installed at the lower part of the power platform. The device is suitable for an inaccessible underwater radioactive environment, is suitable for indirect visual detection and routing inspection of pressurized water reactor nuclear power station primary circuit main parts, nuclear fuel assemblies and a pool cladding plate in normal material change of a nuclear power station and satisfies radiation environment on-site observation real demands after an accident.
