Abstract

(57)【要約】 【課題】風力発電装置は風の吹く場所を探す事が課題で
す。その限られた風の力を増加します。 【解決手段】風車のブレードにディンプルを設ける事に
より風の抵抗を大きくし発電を増大せしめる。 (57) [Summary] [Problem] The challenge for wind power generators is to find a place where the wind blows. Increases its limited wind power. A dimple is provided on a blade of a windmill to increase wind resistance and increase power generation.

Description

【発明の詳細な説明】Detailed Description of the Invention

【０００１】[0001]

【発明の属する技術分野】本発明は風力による発電装置
のブレードにディンプルを設ける事により風の抵抗を大
きくする。TECHNICAL FIELD The present invention increases wind resistance by providing dimples on a blade of a wind power generator.

【０００２】[0002]

【従来の技術】従来の風力発電のブレードにはディンプ
ルは付いていません。[Prior Art] Conventional wind power generation blades do not have dimples.

【０００３】[0003]

【発明が解決しようとする課題】風力発電のブレードに
ディンプルを設ける事により表面積が増えると共に風の
抵抗を強め、ブレードの回転を上げることが出来る。そ
の事により生産電力の増加につながる。By providing dimples on the blade for wind power generation, the surface area is increased and the wind resistance is increased, so that the rotation of the blade can be increased. This leads to an increase in production power.

【０００４】[0004]

【課題を解決するための手段】風力発電はブレードで風

電する。従ってその風車は風を有効に活用する事によ
り、より大きく電気を発電する。従って風の抵抗を大き
くする事がそれにつながります。In wind power generation, wind is received by a blade, and its rotation causes power to be generated by a generator provided on a central axis. Therefore, the wind turbine effectively generates electricity by using wind effectively. Therefore, increasing the resistance of the wind will lead to it.

【０００５】[0005]

【発明の実施の形態】本発明は、風車のブレードの表面
にゴルフボールの表面に付いているようなディンプルを
設ける発明です。BEST MODE FOR CARRYING OUT THE INVENTION The present invention is an invention in which dimples such as those on the surface of a golf ball are provided on the surface of a wind turbine blade.

【０００６】[0006]

【発明の効果】風力は自然のもので、これは増やす事は
出来ませんが、その風力をいかに有効に使用するかを考
えました。ブレードにディンプルを設けますと表面積が
増えると共に風の抵抗も増えます。[Effect of the invention] Wind power is natural and cannot be increased, but we thought about how to effectively use it. Providing dimples on the blade increases the surface area and wind resistance.
