PROBLEM TO BE SOLVED: To provide a flue investigation device capable of investigating the inside of a horizontal flue connected to a chimney even during operation of a blast furnace facility through which flue gas flows.SOLUTION: A flue investigation device 1 for investigating the inside of a horizontal flue connected to a chimney includes: a heat-resistant traveling body 6 traveling inside the flue; an imaging device 7 mounted on the traveling body, and imaging the inside of the flue; a heat-resistant transparent canopy 8 provided in the traveling body so as to cover the imaging device; a heat-resistant luminaire 9 mounted on the traveling body; and a heat-resistant flexible hose 3 supplying refrigerant for cooling from the outside of the flue to the inside of the canopy, supplying power to the imaging device and the luminaire, transmitting traveling drive force to the traveling body, and transmitting/receiving data to/from the imaging device between itself and the outside of the flue.SELECTED DRAWING: Figure 3 |
