Description
風力発電ブレ−ドをコンテナ規格内寸法に収めるプレファブ工法。 A prefabricated method that fits the wind power blades within the container standard dimensions.
輸入が過半である風力発電ブレ−ドは、一体成型のまま輸入されるため、迅速な部品調達や品質管理も難しい。
また、日本の特殊な道路事情から、発電効率の良い大型風力発電所の建設地域は限定され、施設建設の推進には様々な問題が生じている。Wind power generation blades with a majority of imports are imported as a single piece, so it is difficult to quickly procure parts and perform quality control.
In addition, due to the special road conditions in Japan, the construction area of large-scale wind power plants with good power generation efficiency is limited, and various problems have arisen in the promotion of facility construction.
風力発電ブレ−ドは一体成型である為、日本の道路事情では狭小地域への輸送が難しい。
そこで、日本の道路事情等を考慮すれば、特に大型発電ブレ−ドは必然的に分割製作に行き着く。
従って、風力発電の普及には安全かつ確実な分割技術の開発が急務となる。Since wind power blades are molded in one piece, it is difficult to transport to small areas under Japanese road conditions.
Therefore, considering the road conditions in Japan, large power generation blades inevitably end up in split production.
Therefore, it is urgent to develop a safe and reliable splitting technology for the spread of wind power generation.
本発明は、大型風力発電ブレ−ドをコンテナ規格内寸法に収めること。その継手部は外殻をハメ込み、埋め込みボルトで接合することである。
更に、運転騒音防止やひび割れ欠損防止は、表面をエンボス加工した保護シ−ト（ＣＦシ−ト等）を貼ることで解決した。According to the present invention, the large wind power generation blade is accommodated within the container standard. The joint part is to insert the outer shell and join with the embedded bolt.
Furthermore, the prevention of driving noise and cracking defects was solved by applying a protective sheet (CF sheet or the like) whose surface was embossed.
本発明は、ブレ−ドをコンテナ規格に収める分割製作により、輸送コストの削減や風力発電所の建設地域の拡大に寄与します。
また、落雷対策はブレ−ドをＣＦシ−ト等で覆い、合わせ目に導線を組み込み速やかに地中に放電させることで解決した。
従って、本発明は発電可能範囲を広げただけでなく、避雷にも効果的である。The present invention contributes to the reduction of transportation costs and the expansion of the construction area of wind power plants by dividing the blade into container standards.
In addition, lightning countermeasures were solved by covering the blade with a CF sheet, etc., inserting a lead wire at the joint, and quickly discharging it into the ground.
Therefore, the present invention not only widens the power generation possible range but is also effective for lightning protection.
本発明の分割継手により、大型風力発電所を狭小地にも建設出来るようになるが、量産により高品質で且つ廉価な発電施設の建設を可能にしました。 The split joint of the present invention allows large wind power plants to be built in narrow spaces, but has enabled mass production to build high-quality and inexpensive power generation facilities.
（１）狭小地域への大型風力発電ブレ−ドの輸送。
分割製作した発電ブレ−ドは保護シ−トで覆う為、輸送時のひび割れ欠損や運転騒音の解消、そして建設可能地域の選択肢も広げます。
（２）大型風力発電施設の離島や過疎地への設置。
規格化した分割発電ブレ−ドは保護シ−トで覆うから、コンテナ輸送により海陸を問わない輸送を可能にしました。(1) Transportation of large wind power blades to small areas.
The split power generation blade is covered with a protective sheet, which eliminates crack defects during transportation and operation noise, and expands the options for areas where construction is possible.
(2) Installation of large-scale wind power generation facilities on remote islands and depopulated areas.
Standardized split power generation blades are covered with a protective sheet, so container transport can be used regardless of sea or land.
ブレ−ドを埋め込みボルトで接合する継手や、保護シ−トで覆いコンテナ輸送する方式は様々な分野に応用可能です。
例えば、金属加工品や鋼構造物等の重量・長大物もコンテナ規格に分割出来れば安価な輸送が可能になります。The joint that joins the blade with the embedded bolt and the method of transporting the container covered with a protective sheet can be applied to various fields.
For example, if heavy and large items such as metal processed products and steel structures can be divided into container standards, cheap transportation is possible.
