INSPECTOR FOR INNER SURFACE OF PIPE

摘要

PURPOSE:To achieve a safe and quick inspection of a pipe by running a self- propelling truck equipped with a video camera and a detector through a pipe being remote-controlled monitoring a reproduced image with the reproduction of an image signal from the camera in a monitor chamber. CONSTITUTION:A detector 3 is mounted on a self-propelling truck 1 with a running mechanism 2 and moves along the axis of a pipe 7 reciprocatively turning in the circumferential direction thereof 7 to inspect the pipe wall. A detection signal is transmitted with a transmission circuit 13 and recorded on a recorder 4 in a monitor chamber. An image signal outputted from a video camera 10 is reproduced with an image device 15. An instruction signal of a centralized operator 6 operates various points 62 to be instructed. This enables repeated inspection of points suspected of corrosion with emphasis, monitoring a reproduced image of the image device 15 thereby improving the inspection efficiency remarkably.
