米国特許出願公開第２０１１／０１４２６７８号明細書US Patent Application Publication No. 2011/0142678
　さて、近年の風力発電用風車の大型化に伴い、風力発電用風車を構成する風車回転翼の翼長さも長くなり、風車回転翼の翼先端部における周速度も大きくなりつつある。そのため、風車回転翼の翼先端部に雨滴による液滴エロ－ジョン（液滴が衝突して発生するエロージョン：液滴の衝突により衝突された物体が物理的に削られる現象）が発生するおそれがある。 Now, with the recent increase in the size of wind turbines for wind power generation, the blade lengths of the wind turbine rotor blades constituting the wind turbines for wind power generation have become longer, and the peripheral speed at the blade tip portion of the wind turbine rotor blades is also increasing. Therefore, there is a risk of droplet erosion due to raindrops (erosion generated by droplet collision: a phenomenon in which an object collided by droplet collision is physically scraped) at the tip of the wind turbine rotor blade. is there.
　本発明は、上記の事情に鑑みてなされたもので、風車回転翼の翼先端部における母材を雨滴による液滴エロ－ジョンから守り、風車回転翼の耐久性を向上させ、風車回転翼のメンテナンス期間を長期化させることができる風車回転翼および風力発電用風車を提供することを目的とする。 The present invention has been made in view of the above circumstances, and protects the base material at the blade tip of the wind turbine rotor blade from droplet erosion caused by raindrops, improves the durability of the wind turbine rotor blade, and improves the durability of the wind turbine rotor blade. An object of the present invention is to provide a wind turbine rotor blade and a wind turbine for wind power generation capable of extending the maintenance period.
　本発明は、上記課題を解決するため、以下の手段を採用した。
　本発明の第１の態様は、繊維強化プラスチックで形成された外皮材を備えた母材と、前記母材の表面全体に塗布された耐摩耗性を有する保護塗料と、前記保護塗料の翼先端部における前縁部に貼付された耐摩耗性を有する保護テープと、を備えている風車回転翼である。 The present invention employs the following means in order to solve the above problems.
According to a first aspect of the present invention, there is provided a base material provided with a skin material formed of fiber reinforced plastic, a protective paint having wear resistance applied to the entire surface of the base material, and a blade tip of the protective paint.

　本発明の第１の態様によれば、母材の表面全体が保護塗料により保護され、保護塗料の翼先端部における前縁部が保護テープにより保護されることになる。
　これにより、仮に保護テープが雨滴による液滴エロ－ジョンで損傷したとしても、その内側に配置された保護塗料で母材を雨滴による液滴エロ－ジョンから守り、風車回転翼の耐久性を向上させ、風車回転翼のメンテナンス期間を長期化させることができる。
　また、雨滴による液滴エロ－ジョンで損傷した保護テープは容易に交換することができるので、メンテナンス性を向上させることができる。 According to the first aspect of the present invention, the entire surface of the base material is protected by the protective coating, and the leading edge portion of the wing tip of the protective coating is protected by the protective tape.
As a result, even if the protective tape is damaged by droplet erosion caused by raindrops, the protective coating placed inside protects the base material from droplet erosion caused by raindrops and improves the durability of the wind turbine rotor blade. The maintenance period of the wind turbine rotor blade can be extended.
In addition, since the protective tape damaged by the droplet erosion caused by raindrops can be easily replaced, the maintainability can be improved.
　本発明の第２の態様は、繊維強化プラスチックで形成された外皮材を備えた母材と、前記母材の翼先端部における前縁部に塗布された耐摩耗性を有する保護塗料と、前記保護塗料の表面全体に貼付された耐摩耗性を有する保護テープと、を備えている風車回転翼である。 According to a second aspect of the present invention, there is provided a base material provided with a skin material made of fiber reinforced plastic, a protective paint having wear resistance applied to a front edge portion of a wing tip portion of the base material, It is a windmill rotor blade provided with the protection tape which has the abrasion resistance affixed on the whole surface of the protective paint.
　本発明の第２の態様によれば、母材の翼先端部における前縁部が保護塗料により保護され、保護塗料の表面全体が保護テープにより保護されることになる。
　これにより、仮に保護テープが雨滴による液滴エロ－ジョンで損傷したとしても、その内側に配置された保護塗料で母材を雨滴による液滴エロ－ジョンから守り、風車回転翼の耐久性を向上させ、風車回転翼のメンテナンス期間を長期化させることができる。
　また、雨滴による液滴エロ－ジョンで損傷した保護テープは容易に交換することができるので、メンテナンス性を向上させることができる。
　さらに、保護塗料が翼先端部における前縁部のみに塗布されることになるので、風車回転翼の軽量化およびコストダウンを図ることができる。 According to the 2nd aspect of this invention, the front edge part in the blade | wing front-end | tip part of a preform | base_material is protected with a protective coating material, and the whole surface of a protective coating material is protected with a protective tape.
As a result, even if the protective tape is damaged by droplet erosion caused by raindrops, the protective coating placed inside protects the base material from droplet erosion caused by raindrops and improves the durability of the wind turbine rotor blade. The maintenance period of the wind turbine rotor blade can be extended.
In addition, since the protective tape damaged by the droplet erosion caused by raindrops can be easily replaced, the maintainability can be improved.
Furthermore, since the protective coating is applied only to the leading edge portion at the blade tip, the weight and cost of the wind turbine rotor can be reduced.
　第１および第２の態様において、前記翼先端部における前縁部は、雨滴による液滴エロ－ジョンの発生するおそれがある領域であるとさらに好適である。 In the first and second embodiments, it is more preferable that the leading edge portion of the blade tip portion is a region where there is a risk of droplet erosion due to raindrops.

When rotating, the peripheral speed is in the range of 100 m / sec to 80 m / sec, and the front edge is 0% to 10% of the rear surface when the front edge is 0% and the rear edge is 100%. And an area of 0% to 10% on the back surface is more preferable.

　ここで、メンテナンス期間の長期化が図れることは、特に、頻繁にメンテナンスを行うことのできない洋上風車（洋上に設置される風力発電用風車）にとって有利なメリットになる。 According to the third aspect of the present invention, the base material at the blade tip of the wind turbine rotor blade is protected from droplet erosion caused by raindrops, the durability of the wind turbine rotor blade is improved, and the maintenance period of the wind turbine rotor blade is extended.
