Abstract
A self-cleaning intake screen assembly for preventing debris, fish, and other wildlife from being transferred from a waterway such as a lake or river, which includes a conical support structure, a screen and a screen sweeping assembly. The conical support structure has a circular base, a cap plate, and a plurality of support studs extending therebetween. The screen extends between the base and the cap plate and is affixed to the support studs. The screen sweeping assembly is rotatably mounted to the cap plate for sweeping debris off of the screen. A flow restrictor is disposed inside the conical support structure for restricting water flow through a portion of the screen in order to reduce differences in water flow rates through different portions of the screen.
