PURPOSE:To increase the brightness of a subject and to perform confirmation over the entire range of a flow nozzle by composing an inspecting device of a moving carriage which has a rotating mirror and is moved while suspended from a wire and a camera provided facing the mirror. CONSTITUTION:Posts 7 and 8 and a stay 18 for telecamera fixation are fixed to flanges 4 and 4a with bolts 9. One terminal of the wire 6 for suspending the moving carriage is fixed to a ring 11, and the other terminal is pulled from outside a feed water pipe 1 through a guide 15 fitted to the moving carriage 5 and a roller 12 for wire operation and fixed with bolts 9, etc. Consequently, the moving carriage 5 is suspended from the wire 6 and positioned in the center of the feed water pipe 1. When a motor 5c is driven through remote operation, the rotating mirror 5a rotates at a low speed to reflect the surface of the flow nozzle 2 lighted by an illumination lamp 14. Then the surface of the flow nozzle is projected upon the telecamera 19 through a fixed mirror 10. At this time, the lens 20 is zoomed and put in focus to obtain a sharp image. |
