IPC: F17C13/02
Filed: 1986-04-30
Abstract: PURPOSE:To make it possible to carry in a robot with a tank operating by temporarily providing an air-tight room by covering a nozzle at a roof and releasing the nozzle after making the inside inert atmosphere and pressurizing so as to carry in the inspection robot into inside the tank. CONSTITUTION:When carrying in a robot into inside a tank, an air-tight room 15 is temporarily provided by covering a manhole at the roof of the tank and the air inside the air-tight room 17 is replaced with the herium gas. The herium gas is charged until it becomes equal to the gas pressure inside the tank and then the robot is hung down into inside the tank and a cover 4 is released. Therefore the robot for inside inspection can be safely carried in into inside the tank charged with combustible gas or the like.
