Abstract
Visual pipe and cavity inspection systems including camera heads for video and/or image capture and associated coaxial video push-cables having increased durability and strength, for high frequency alternating current electrical power transmission as well as data and/or video signal communication between the camera heads and a display or control device, are disclosed.
Claims26
A system for video inspection of piping or cavities, comprising:
- a camera head including a video signal transmitter;
- a coaxial video push-cable having a proximal end and a distal end, the push-cable comprising:
- an inner conductor;
- an insulating dielectric layer comprising a longitudinal strength material having partial flexibility disposed around the inner conductor;
- an outer conductor array comprising a plurality of individual conductors;
- and
- an outer partially flexible structural element disposed around the tubular insulating element;
- wherein an output of the video signal transmitter is coupled to the conductor at the distal end of the push-cable to send a video signal;
- an electrical motor disposed at the distal end of the coaxial video push-cable;
- and
- an AC power supply operatively coupled at a proximal end of the push-cable;
- wherein the video signal transmitter receives alternating current (AC) electrical power provided from the coaxial video push-cable to power the video signal transmitter and the electrical motor received AC electrical power provided form the coaxial video push-cable to power the electrical motor.
