Abstract
Systems for energizing a drain cleaning cable within a drain line or other region of interest are described. A signal transmitter on an end portion of the cable enables the cable end portion to be sensed or located when in a pipe or conduit underground. Also described are electrically conductive drivetrains for transferring rotary power.
Claims15
A method for determining location of a conduit, pipe or other construct, wherein the method comprises:
- providing a system including (i) a machine having a drum, an input shaft for receiving rotary power, and a cable extending from the machine, the cable including an inner rotatable core and an outer sheath extending about the inner core, wherein upon the input shaft receiving rotary power, the inner core rotates independently from the outer sheath, and (ii) an electrical signal transmitter in electrical communication with the input shaft of the machine, wherein the input shaft of the machine is in electrical communication with the cable;
- actuating the electrical transmitter to thereby energize the inner core;
- and
- sensing an electromagnetic field emanating from the energized inner core.
