Patent ID: 8308424

Claim:
A helical turbine power generation system, the system comprising: a frame including: a fixing member rectangular in shape, and a protruding member including triangular frames on both sides in contact with the fluid flow, wherein the protruding member protrudes out perpendicular to a shaft of a helical turbine disposed in the fixing member, and the helical turbine rotatably provided vertically in the fixing member of the frame behind the protruding member, the helical turbine configured to continuously generate a rotation force under unidirectional or multidirectional fluid flow; a step-up gear rotatably connected to the helical turbine to increase a rotational velocity of the helical turbine up to a level required for generating electricity; and an induction generator connected to the step up gear to generate electricity by using the rotational velocity transferred from the step-up gear, wherein the helical turbine further comprises: a plurality of additional supporting members radially protruding from the shaft, in which the additional supporting members are shorter than the supporting members, alternate with the supporting members, and are multilayered in series; and at least one additional blade having a helical structure, in which the additional blade is connected to ends of the additional supporting members, has a streamlined cross section, and twists in a longitudinal direction of the shaft, and wherein the triangular frames on both sides in contact with the fluid flow, prevent floating matter included from attaching to the fixing member and a plurality of slits parallel to a direction of the fluid flow, which are formed on both protruding sloping sides of the protruding member, the plurality of slits are configured to prevent matter floating in the fluid from disturbing fluid flow.
