Wind-driven electricity generation device with segmented rotor

摘要

A vertical wind-driven electricity generation device is described, which, in one embodiment, utilizes a segmented Savonius rotor and which is easily handled, transported, assembled and maintained, even by a single person. The blades of the rotor are segmented into a plurality of modest size blade segments, each of which comprises two, low height, helically-curved blade portions. The blade segments are preferably of the same height and diameter. The rotor is mounted on a central vertical shaft connected to a generator. When the plurality of blade segments are installed on the device's central shaft, the overall blade configuration functions as an unitary Savonius rotor. Flow of gas (normally air in the form of wind) causes the rotor to move, turning the shaft and rotating member of the generator to rotate, causing the generator to produce electricity.

主权项

1. An apparatus for wind-driven generation of electricity, comprising:
an electrical generator, wherein the generator comprises a rotating member for generating electricity as the rotating member turns in relation to a base; an elongated shaft extending from said base, wherein one end of the shaft is operably attached to the rotating member; and a segmented rotor attached to the shaft comprising a plurality of blade segments, the plurality of blade segments forming parallel helical surfaces, each of the blade segments comprising: a sleeve comprising at least two upper struts extending from a first portion of the sleeve and at least two lower struts extending from a second portion of the sleeve, the sleeve further comprising an aperture sized and shaped to install onto the elongated shaft; and at least two blades that are positioned in a fixed relationship with respect to one another, each of the at least two blades attached to the at least two upper struts and the two lower struts, the blades being spaced apart from the sleeve by the struts.
