Abstract
The present invention relates to a pipeline interior surface cleaning device that is propelled through the pipeline by the operational properties of the transported medium. A speed regulator controls the rate of forward motion of the device and a series of off-axis wheels enables the device to travel in a spiraling motion through the pipeline. A series of sealing members, scraping elements, brushes and magnets loosen and collect particles on the interior pipeline surface as the cleaning device spirals through the pipeline.
Claims18
A device for cleaning the interior surface of a pipeline for transporting a medium, the device comprising:
- means for removing particles on the interior pipeline surface;
- means for regulating the forward speed of the cleaning device;
- and
- means for rotating the cleaning device as it travels through the pipeline.
A device for cleaning the interior surface of a pipeline for transporting a medium comprising:
- a carrying body adapted to be received in the inside of a pipeline;
- a first scraper and a first brush disposed on the carrying body, the first scraper and first brush configured to loosen particles on the interior pipeline surface;
- a first magnet disposed on the carrying body distal to the first scraper and first brush, the first magnet being configured to collect particles loosened by the first scraper and first brush;
- a central port in the carrying body configures to enable the transported medium to pass through the cleaning device;
- a speed regulator disposed on the carrying body at a first end of the central port responsive to the transported medium and configured to regulate the forward speed of the cleaning device by regulating the passage of the transported medium through the cleaning device;
- a rotator disposed on the carrying body and responsive to the forward movement of the cleaning device for rotating the cleaning device as it travels through the pipeline.
