Abstract

A debris clearing system for clearing debris from a drain strainer includes a base member having at least one attachment coupler configured to removably attach the base member to the drain strainer, a support frame rotatably coupled to the base member, at least one arm assembly coupled to the support frame, a clearing member coupled to a distal end of the at least one arm assembly. The clearing member being adjacent the exterior surface of the drain strainer when the base member is coupled to the drain strainer. The system includes a drive unit coupled to the support frame to rotate the support frame and the at least one arm assembly relative to the base member. The clearing member clears debris from the exterior surface of the drain strainer when the drive unit rotates the support frame and the at least one arm assembly.

Claims5

Dependent claims

A method of clearing a drain strainer coupled to a roof drain on a roof, comprising:

providing a debris clearing system mounted to the drain strainer, the debris clearing system including:
at least one arm assembly;
a clearing member coupled to a distal end of the least one arm assembly, the clearing member positioned adjacent an exterior surface of the drain strainer;
a water diverting member coupled the distal end, the water diverting member being sized and shaped to divert water away from the drain strainer as the at least one arm assembly rotates about the drain strainer, wherein the water diverting member leads the clearing member as the at least one arm assembly rotates about the drain strainer;
and
a drive unit operatively coupled to the at least one arm assembly
operating the drive unit so as to rotate the at least one arm assembly and the clearing member about the exterior surface of the drain strainer;
and
clearing debris from the exterior surface of the drain strainer as the clearing member moves adjacent to the exterior surface.
