Abstract:
PCT No. PCT/FR97/00902 Sec. 371 Date Nov. 16, 1998 Sec. 102(e) Date Nov. 16, 1998 PCT Filed May 23, 1997 PCT Pub. No. WO97/45761 PCT Pub. Date Dec. 4, 1997An endoscopic probe includes an inspection head attached to the end of a longitudinally flexible supporting line which connects it to an operating unit provided with means for moistening the line. The supporting line (2) is rigid under axial torsion, whilst the inspection head (1) is movable in axial rotation and is formed by a demountable assemblage of two parts: a permanent part (11), attached to the end of the supporting line by means of a rotary joint (10) and housing a miniaturized photography device (26), and an interchangeable part (12), fastened rigidly to said permanent part in the extension of the latter with the aid of a demountable joint (44) and comprising a parietal (lateral or axial) orifice provided with a wide angle ocular lens (23) followed by an optical line (25) for conveying the light energy picked up by said lens toward the photography device (26). A motor system and encoder (32 to 36) are mounted in the probe for motorizing the axial rotation of the inspection head and ensuring adjustment of its angular position in relation to the supporting line. The endoscopic probe is suitable for the visual inspection of the flues of coke ovens.
