Helical turbine with tapered and helical cutting edges for converting hydrodynamic energy into electrical energy

摘要

A helical multi-piece auger that is rotatable by a moving fluid for the generation of energy is provided. The helical multi-piece auger may include several interior pieces and two tapered end-pieces mounted on a central shaft. The pieces may include an outer spiral flange perpendicular, in both directions, to a portion of helical auger. Each tapered end-piece may be tapered with respect to both the outer diameter of a helical auger portion, and the width of an outer spiral flange. Each tapered end-piece may have an outer edge that effectively merges with the central shaft of the multi-piece auger over a radial arc of between 90 and 180 degrees. The helical multi-piece auger may include wing-shaped nose cones that are axially offset with respect to each other and house hydraulic components. The helical multi-piece auger may be rotatable by the moving fluid to facilitate generation of energy.
