Abstract
A wind driven cleaning ring apparatus for removing dirt on electrical insulators used in electric systems. The cleaning ring apparatus includes spaced apart bowl members supported on a cylindrical ring member by being sleeved over the ring member or formed integral therewith. The bowl members may be hemispherical or conical in shape and may be held spaced apart on the ring member by spherical or cylindrical beads. The bowl members may include a peripheral scraper edge. Spaced apart circular brushes and/or scraper members may be mounted on the ring member between respective ones of the bowl members.
Claims20
An electrical insulator having a generally upwardly facing surface, in combination with a wind driven cleaning ring apparatus disposed on said surface of said insulator and for cleaning said surface of said insulator comprising a plurality of members supported on a ring and secured to said ring spaced apart from each other and engaged with said surface of said insulator for cleaning dirt from said surface of said insulator by scraping said surface of said insulator in response to wind driving said members to rotate said apparatus with respect to said insulator.
An electrical insulator having a generally upwardly facing surface, in combination with a wind driven cleaning ring apparatus disposed on said surface of said insulator for cleaning said surface of said insulator comprising a generally cylindrical ring member and a plurality of bowl shaped members supported on said ring member and retained spaced apart from each other and engaged with said surface of said insulator for cleaning dirt from said surface of said insulator by scraping said surface of said insulator in response to wind driving said bowl members to rotate said apparatus with respect to said insulator.
An electrical insulator having a generally upwardly facing surface, in combination with a wind driven cleaning ring apparatus for cleaning said surface of said insulator comprising a plurality of generally cylindrical brush members supported on and retained spaced apart on a ring and disposed on and engaged with said surface of said insulator for brushing dirt from said surface of said insulator in response to wind driving said ring apparatus to rotate with respect to said insulator.
