Nuclear power station visual foreign matter grabbing device

The invention belongs to the technical field of nuclear power, and particularly relates to a visual foreign matter grabbing device for a nuclear power station. According to the visual foreign matter grabbing device for the nuclear power station, a worm and gear structure is adopted for mechanical transmission, the self-locking characteristic is achieved, and stability is good; a camera and a cable of a light source penetrate through the interior of the motor stator, tool miniaturization is facilitated, the trafficability in a narrow space is good, and reliability is high; an integrated mechanism of the camera shooting assembly and the claw can be operated by a single person, the problems that in traditional foreign matter grabbing work, an endoscope and a grabbing tool need to be used in cooperation, operation is inconvenient, and winding occurs are solved, the number of field operators is reduced, the collective dosage can be reduced easily, and optimization of radiation protection is achieved. 本公开属于核电技术领域，具
