摘要： An electric generator assembly driven by a waterwheel (6) wherein the axial length of the waterwheel (6) is substantially greater than the diameter thereof and contains a speed-increasing device (20) for driving a high speed generator (30). The assembly is supported from a bridge spanning the full axial length of the waterwheel (6) and the bridge (40) also supports an adjustable chute (60) extending from the dam crest (44) to the waterwheel (6). The waterwheel (6) has longitudinal buckets (10) designed to develop mxamimum energy over a wide range of flows. The buckets (10) are vented as necessary to improve filling and discharge and also minimize vibration. The complete bridge assembly is supported adjacent opposite ends by hydraulic cylinder units (50) connected to and adapted to raise the unitary bridge, chute and waterwheel assembly above increased tailwater levels to reduce drag and rotating friction. A synchronous or induction generator (30) with a rotating rotor (34) and non-rotatable stator (32) is incorporated into the waterwheel in order to generate electric power. Retention of water in the buckets (10) until each one reaches the lowest point of travel is provided by an adjustable shroud (80).
