Abstract
A fluid power generator can enhance power generation efficiency by efficiently using the drag force of wind without increasing the size of blades, and includes: an ascending air current-forming body provided at a rotary shaft; a plurality of spiral blades which are spirally formed along the outer circumferential surface of the ascending air current-forming body; and a generator which generates electricity by rotation of the ascending air current-forming body.
Claims10
A fluid power generator comprising:
- an ascending air-current forming body installed on a rotary shaft;
- a plurality of spiral blades spirally arranged along an outer circumferential surface of the ascending air-current forming body;
- a generator configured to produce electricity by rotation of the ascending air-current forming body;
- a first auxiliary drag blade integrally connected to each spiral blade to be inclined against a surface of the respective spiral blade along an edge of the respective spiral blade to trap wind;
- and
- a second auxiliary drag blade disposed at an upper end portion of each spiral blade,
- wherein the ascending air-current forming body has a lower outer diameter larger than an upper outer diameter,
- wherein each spiral blade has a horizontal width gradually increasing upward from a bottom thereof.
