device for highly migratory fish from downstream.

摘要

The invention relates to a device for diverting fish migrating downstream, comprising a step in the flow, arranged perpendicular to the direction of flow and situated in the floor of a turbine inlet channel, with one or several funnel-shaped, drainage openings, which are inclined downwards. Said openings feed into a collector, by means of one or several drain pipes, which are inclined downwards, from whence one or several by-pass pipes lead into the downstream section. The construction is arranged such that no loss of nominal power occurs.
