摘要: A device for photographing the interior of pipelines is disclosed. The device deposited at the pipeline's inlet and is drawn through the pipeline by fluid flow. The combination of a ballast device and a floatation device and a rudder maintain the device in proper orientation. The device is untethered and is powered by a battery carried in the vessel. A control circuit permits a time delay before operating the camera and lights.
