Patent ID: 10697901

Abstract:
A pipe inspection device includes a housing (1) fixed to a semi-rigid rod (2) and having a longitudinal axis (3) and inside the housing a camera (4) having a forward-looking field of view and a camera (5) rotatable around said longitudinal axis (3) and having a field of view directed to permit closer inspection of an inner surface of the pipe, and means (17-24) for rotating the rotatable camera (5) to direct its field of view against an area of the inner surface of the pipe to be inspected more closely. To make it possible to inspect the inner surface of a pipe faster than with prior art devices, the inspection device has at least two cameras (5-7) in addition to the camera (4) having a forward-looking field. Said at least two cameras (5-7) are rotatable as an assembly around the longitudinal axis and have a field of view directed to permit closer inspection of an inner surface of the pipe. Further, the housing (1) has a fixed rear part (10) and a front part (11) that is carried by the rear part (10) and rotatable around said longitudinal axis (3), all of the cameras (4-7) being fixed in the rotatable front part (11) of the housing (1).
