ABSTRACT:
The device comprises a flexible pipe (15) having one of its ends in a zone (20) situated outside the water box (6) and its other end joined to a tubular probe-guide (16) supported by a handling device (13, 14) inside the water box (6). A sheath (21) is slideably mounted inside the flexible pipe (15) and has mounted at one of its ends a stop and a bush for guiding the ultrasonic probe (18). A Bowden cable (22) is mounted rotatably about its axis inside the sheath (21), and is integral at one of its ends with a profiled rotational driving part and joined at its other end, outside the water box (6), to a motor (24). The support for the probe (18) has a threaded part engaged in a tapped part of the guide bush and can be driven in rotation by a profiled part integral with the end of the Bowden cable (22). The support for the probe (18) is thus driven in rotation and axial translation so as to perform a helical movement.
