Embodiment Construction

[0033] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Detailed descriptions of known functions and constructions are omitted in order to clarify the description of the present invention.

[0034] Figures 3 to 5 A wind turbine according to a first embodiment of the invention is shown. refer to Figures 3 to 5 , The wind turbine according to the first embodiment of the present invention includes a support unit 110 , a rotating cylinder 120 , a rotating shaft 130 , an upper bearing 140 , a lower bearing 150 , a plurality of blades 160 , and an angle limiting device 170 . The configuration of this wind turbine facilitates that the blades 160 are opened outward relative to the rotating drum 120 or are in close contact with the outer circumferential surface of the rotating drum 120 according to the position of the wind force.

[0035] The support unit 110 is supported on the ground to support t...

Abstract

Disclosed herein is a wind turbine. The wind turbine includes a support unit having a lower base block and a cylindrical protruding part. A rotary cylinder is rotatably supported by the protruding part. A rotating shaft extends from a center of the rotary cylinder to rotate along therewith. An upper bearing is installed on the protruding part to support the rotary cylinder. A lower bearing is installed on the lower base block to support the rotary cylinder. A plurality of vanes is installed along the outer circumference of the rotary cylinder at regular angular intervals, and is opened outwards relative to the rotary cylinder or closed to be in close contact with the outer circumference of the rotary cylinder, according to a position relative to a wind direction. An angle limiting means prevents each vane from being opened beyond a preset angle.

Description

technical field [0001] The present invention generally relates to a wind turbine, and more particularly, to a wind turbine capable of achieving high power generation efficiency by reducing rotational resistance generated by blades provided on a rotating cylinder to provide rotational force to the rotating cylinder. Background technique [0002] Generally, as the world's industry develops and the population expands, resources such as oil, coal, or natural gas are increasingly depleted. Therefore, as an alternative energy source, much research has been conducted on a wind turbine using wind power to generate electricity. [0003] Meanwhile, a horizontal wind turbine that has been widely used has a configuration in which a rotor having a plurality of blades is disposed at an upper end of a structure that stands vertically on the ground. Such a horizontal wind turbine operates as follows. That is, the rotor is rotated by the wind, and the mechanical energy generated by the rot...
