Abstract
PURPOSE: To prevent the swing of the vortex and the separation of water flow by means of a vortex swing preventing plate provided to divide the semicircular intake port into two, right and left, and a projection on the dam wall side in an intake apparatus with a semicircular intake port used as a dam outlet works.
CONSTITUTION: Overflow water falls through the body 2 of the intake apparatus from the semicircular intake port and flows through an effluent pipe 3. In the case of the complete overflow or the submerged overflow, there is no substantial problem. But in the case of incomplete overflow, the vortex converging on the semicircle center of the intake port violently swings parallel to the dam wall surface 4 to cause a noise. Since the flow speed in the body 2 is fast on the side of the dam wall surface 4 and slow on the dam side, the water is separated at the upper portion of the inlet of the effluent pipe 3 eventually causing a cavitation. Therefore, a vortex swing preventing plate 6 is provided to divide the semicircular intake port 1 into two, right and left, and a semicircle ring-shaped projection 7 at the upper portion of the inlet of the effluent pipe 3 to prevent such adverse phenomena.
