Bent tube inspection probe with a rotary inspection head

Bent tube inspection probe for ultrasonically inspecting a tube said probe comprising a cable having electrical conductors and a probe head fixed to one end of the cable, with said probe head comprising:

• an inspection head, means for transmitting and receiving tube inspection signals;
• support means for rotationally mounting said inspection head (18);
• a motor for rotating said inspection head relative to said support means;
• an encoder connected to the motor for detecting the presence of faults in said tube and a rotary collector positioned between the motor and said support means to ensure a mechanical connection between the motor and the inspection head and to transmit electrical control signals for controlling the transmitting and receiving means and electrical signals from said transmitting and receiving means, with said probe further comprising articulated mechanical connections disposed between the motor and the rotary collector and between the rotary collector and the inspection head and a sheath flexible in flexion and rigid in torsion for joining said support, to said motor and to said rotary collector to prevent relative circumferential displacement thereof.
