Title:
CAMERA SYSTEM FOR PIPE INSPECTION
Document Type and Number:
WIPO Patent Application WO1997022030
Kind Code:
A3
Abstract:
When the camera system for pipe inspection is pushed forward through the pipe by means of a rod, the camera housing has a tendency to rotate uncontrollable about its longitudinal axis, especially when passing through curved pipe sections. In order to ensure that the camera in the housing nevertheless always supplies properly oriented and upright images to the monitor connected to it, the camera module can rotate about the longitudinal axis of the housing and has a weight, the centre of gravity of which lies beneath the axis of rotation with the camera horizontal. Thus the camera always assumes a horizontal position even when the housing rotates.
