Pipe inspection system with jetter push-cable

摘要

Pipe inspection and pressurized fluid cleaning systems, methods, and apparatus are disclosed. A jetter push-cable device may include a high-pressure hydraulic hose core with a helical surround of small-diameter flexible rods and/or conductors, wrapped in such a way as to provide a cable of low bend-radius for use in small-diameter pipe inspections and cleaning. Conductors may be included in the push-cable. End-effectors, such as jetter nozzles and cutters may be coupled to the push-cable. An annular camera assembly, which may include lighting elements, may be further included in the push-cable device.

主权项

1. An apparatus for pressurized pipe cleaning, comprising:
a push-cable structure comprising: a hose having a central channel configured for transmitting fluid under pressure through the push-cable structure; a stiffening structure helically wrapped around the hose to provide rigidity to the push-cable structure comprising a plurality of rods; and a jetter nozzle coupled to a distal end of the push-cable structure, the jetter nozzle configured to control a flow of the pressurized fluid from the distal end of the push-cable.
