Patent ID: 7347933

Claim:
A self-cleaning intake screen for filtering material from a flow of water, comprising: a rotatable intake screen comprising: a cylindrically shaped sidewall formed of spaced apart wires extending circumferentially around a center of the intake screen and defining openings therebetween for passing a flow of water, and support members extending longitudinally across and supporting inner surfaces of the spaced apart wires; a manifold extending within the rotatable intake screen; and a first cleaning element operatively coupled to the intake screen so as to remove material from the intake screen during rotation of the intake screen, wherein the first cleaning element is a brush having bristles configured to engage with and remove material from the support members and the wire inner surfaces, and to protrude into and remove material from the openings, and wherein the first cleaning element is rotatably coupled to the intake screen so that rotation of the intake screen in a rotation direction induces rotation of the first cleaning element in the rotation direction.
