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.
Claims27
A screen intake apparatus for a flat surface in a water source, comprising:
- a body configured to be mounted on the flat surface in the water source, the body defining a hollow therein and having an outlet;
- and
- a first curved screen configured to be mounted on the flat surface and defining a first interior therein, a first end of the first curved screen connected to the body, and
- at least one first flow modifier disposed between the first curved screen and the body and placing the first interior of the first curved screen in communication with the hollow of the body.
A screen intake apparatus for a floor of a water source, comprising:
- a base resting on the floor of the water source and having a top surface;
- a body mounted on the top surface of the base, the body defining a hollow therein and having an outlet, the outlet having an longitudinal axis substantially parallel to the top surface of the base;
- and
- at least one curved screen mounted on the top surface of the base and defining an interior therein, a first end of the at least one curved screen connected to the body and placing the interior of the at least one curved screen in communication with the hollow of the body.
A screen intake method, comprising:
- constructing a platform having a top surface;
- mounting a body on the top surface of the platform, the body defining a hollow therein and having an outlet, the outlet having an longitudinal axis substantially parallel to the top surface of the platform;
- and
- mounting at least one curved screen on the top surface of the platform adjacent the body such that an interior of the at least one curved screen communicates with the hollow of the body;
- disposing the platform, the body, and the at least one curved screen in a water source;
- and
- connecting an outlet of the body to piping.
