<P>PROBLEM TO BE SOLVED: To reduce flow resistances and resist external pressures and impact loads. <P>SOLUTION: A screen intake has a central body with two screens attached on either end. Each of the screens has an interior that communicates with a hollow of the body via flow modifiers. These flow modifiers include one or more pipes disposed in the interior of the screens and through passages in ends of the body. A flow control support device disposed within the body supports the body's sidewall and divides the hollow into at least two portions, each communicating with flow from one of the flow modifiers. The flow control support device includes one or more plates disposed adjacent one another within the hollow with a peripheral edge of the plate attached to an inside of the body's sidewall. At least one of the one or more plates can be solid, or the one or more plates can define openings therein allowing passage of at least some fluid through the openings. <P>COPYRIGHT: (C)2013,JPO&INPIT |
