Abstract
A variable dam for a water channel having a longitudinal flow axis includes a frame having a bottom member extending across the channel and upright end members. A plurality of approximately planar plates are each connected by a pivot pin at one lower corner to a journal in the bottom member, the plates being in overlapping or staggered relationship with their respective planes approximately normal to the flow axis. The plates are movable by motors effective to rotate at least some of the pivot pins and are assisted in moving simultaneously by a link pivotally connected to each panel near an upper corner thereof. Guys extend to the panels from anchor blocks in the channel either upstream, or downstream, or both.
Claims9
A variable dam for a longitudinal water channel comprising a frame including a bottom member extending approximately transversely of said channel and including upright members at the ends of said bottom member;
- a plurality of elongated, planar panels each having a corner;
- a pivot pin having a longitudinal and horizontal axis interconnecting said corner of each of said panels for rotation relative to said bottom member with said panel in a relationship having an overlap with adjacent ones of said panels;
- each of said pivot pins being parallel to others of said pivot pins and having a longitudinal offset relative to other pivot pins comparable to said overlap;
- and means for swinging said panels on said pivot pin axes between substantially horizontal and vertical positions.
