Abstract

By the forces of an ordinary wind, a typhoon and a gust, a hydraulic oil pump is rotated to create a pressure in a control valve, so that a generator is rotated to generate electricity by the wind power through a hydraulic cylinder having a foldable propeller, a hydraulic cylinder for widening the propeller, a propeller shaft, a propeller shaft post, a bearing, a propeller shaft post angle adjusting bracket, and a propeller shaft post angle adjusting bracket shaft.

Description

明 細 書 風速による羽の角度自動変換装置 技術分野  Written book Automatic wing angle converter by wind speed Technical Field

本発明は、弱風時における発電効率を最大限にし、強風時に風力発電機の損傷を 防ぐプロペラに関する。 背景技術  The present invention relates to a propeller that maximizes power generation efficiency during light winds and prevents damage to a wind power generator during strong winds. Background art

近年の環境問題への関心の高まりから、自治体を中心に風力発電機の設置が多く 見られるようになつたが、風量の少なさによる発電効率の少ないことや、強風による風力 発電機の破損が報告されているのが現状である。このため本発明は風の強弱に伴い、 羽の角度を調整することにより、最大限の発電効率を保つとともに強風による破損を防 ぐことを目的としている。 発明の開示  Due to the increasing interest in environmental issues in recent years, many wind turbines have been installed mainly by local governments. However, the power generation efficiency is low due to low wind volume, and wind power generators are damaged by strong winds. The current situation is being reported. Therefore, the present invention aims to maintain the maximum power generation efficiency and prevent breakage due to strong winds by adjusting the wing angle according to the strength of the wind. Disclosure of the invention

本発明はプロペラを油圧シリンダーにより開閉することによ y風量ごとの最大効率を 引き出せる状態を保つことが可能となる。さらに、強風時にプロペラをたたむことによって 風によるたわみ、ゆがみ、破損を防ぐことができ、風力発電機の損傷を未然に防ぐことが 可能となる。 図面の簡単な説明 According to the present invention, it is possible to maintain a state in which the maximum efficiency for each air volume can be obtained by opening and closing the propeller by a hydraulic cylinder. Furthermore, by folding the propeller during strong winds, it is possible to prevent wind deflection, distortion, and breakage, and it is possible to prevent damage to the wind power generator.
