PIPE LINE CLEANER AND SEALER

摘要

A device that can be moved through a pipe to treat its interior surfaces with a washing or sealing fluid composition including a container with fluid under pressure and a conduit leading from the container to a rotary nozzle. The conduit terminates in a head that is fixed to the conduit and housed within the nozzle. The nozzle and head are spaced from one another and have one or more passages and ducts respectively, each of which extends laterally relative to the conduit. The passage in the head can be curved so that a turbine structure is formed and exiting fluid creates a force to assist in rotating the nozzle. The nozzle can also be rotated by a motor that is mounted on the conduit and in direct drive with the nozzle. Various rotatable nozzles can be interchanged with one another so that the interior of a pipe can be air cleaned, coated and/or wiped with a wiper blade or otherwise treated with a fluid material. Also, a probe attachment can be placed in communication with a duct of the nozzle to extend a feeler element under pressure and thus assist in detecting plugs and holes in the pipe. A TV camera is normally attached at the front end of the nozzle for viewing the action of the nozzle and/or probe.
