Abstract
A screen intake apparatus has a concrete platform resting on a water source floor. A screen intake anchors on the platform and forms a half cylinder thereon. A barrier at one end of the platform in divides the flow of water. The screen intake has a half-cylindrical body and half-cylindrical screens. Transition walls in the screen intake divide the body's hollow and the screens' interiors, and at least one flow modifier communicates the interior with the hollow. These flow modifiers also form a half cylinder with the platform. A manifold in the screens receives a supply of air to clear debris. Forming a half-cylinder, the screen intake on the platform can have a much lower profile for the water source than the normal cylindrical screens, which require half of its diameter in clearance above and below.
Claims14
A screen intake apparatus, comprising:
- a solid base having a top surface and being disposed in a water source;
- a body mounted on the top surface of the base, the body having first and second ends and defining a hollow therein, the body having an outlet in communication with the hollow;
- a first half cylinder screen disposed on the first end of the body, sealingly mounted on the top surface of the base, and defining a first interior;
- at least one first flow modifier disposed between the first screen and the body and placing the first interior in fluid communication with the hollow;
- a second half cylinder screen disposed on the second end of the body, sealingly mounted on the top surface of the base, and defining a second interior;
- and
- at least one second flow modifier disposed between the second screen and the body and placing the second interior in fluid communication with the hollow.
