| description | The invention relates to the technical field of nondestructive testing of nuclear power stations, and particularly discloses a video inspection device and method for an omega welding seam at the lowerpart of a control rod driving mechanism. The device comprises a vehicle body, a multi-degree-of-freedom mechanical arm and a pan-tilt camera, wherein the vehicle body can go straight, retreat and make a turn; the multi-degree-of-freedom mechanical arm is arranged on the vehicle body, and the multi-degree-of-freedom mechanical arm can be folded or the end of the multi-degree-of-freedom mechanicalarm can be lifted by a certain height; the pan-tilt camera is arranged at the end part of the multi-degree-of-freedom mechanical arm; and when the multi-degree-of-freedom mechanical arm is in a foldedstate, the inspection device can integrally enter a heat preservation layer through a vent hole in the upper end of a pressure container. According to the device and the method, problems in video inspection of a closed space a |
