Description
本発明の特徴としては風力発電装置がスラスト軸受のある上部の定常ダクトに設置されている。3つの(内側)フラップが発電装置のスラスト軸受の下部に実装されている。これらフラップはステンレス板金から構成され全く同一である。また、システムを完璧なバランスを保ち、摩擦や振動により性能が低下しないようにするために、これらフラップ間の隅角を120度にして最大可能精度を得るようにしている。他の3つのフラップ(外側)は前記フラップに固定されている。外側フラップは空気力学的断面を備え、太陽照射や天候状況に耐性のある特殊なプラスチックから構成される。これらフラップには先端支持用の特殊なリブおよび筐体があり、フラップの内側に装着されたワイヤーロープで破損時の拡散を防止している。内側フラップにより小さい風速での始動が可能になる一方、外側フラップにより毎分回転数、張力および性能が高くなる。
抑制フラップは特殊な空気力学的断面を備えて設計され、安全上の理由から破損時に部品が拡散するのを防ぐワイヤーロープ(16)を内部に有する。特殊ワイヤーロープは特殊部(17)で終結して所望通りに引き伸ばされる。
Claims (4)
- 定常型風入射角を有する複数の内側フラップ(2)、および前記内側フラップ(2)に接続され、可変型風入射角を有し、過速抑制機能を有する複数の外側フラップ(8)を備えた垂直軸型風力発電装置であって、
前記外側フラップ(8)はそれぞれ対応する前記内側フラップ(2)と接続するための特殊部(7)を備え、前記特殊部(7)は連結部(9)で前記内側フラップ(2)に回転自在に固定されるとともに、バネ(15)に接続された第1のピン(14)を備え、前記バネ(15)の他端は前記内側フラップ(2)に固定された第2のピン(12)に接続され、
さらに、隣接した前記特殊部(7)を相互に連結するための複数の特殊金属板(10)を備え、前記特殊部(7)と前記特殊金属板(10)は相対継ぎ目(4)で回転自在に固定され、
前記バネ(15)の引張力と、前記外側フラップ(8)の遠心力によって前記第1のピン(14)に印加される力との強弱により、前記風力発電装置の回転数に応じて、前記外側フラップ(8)の対応する前記内側フラップ(2)に対する傾斜角度が変化し、前記外側フラップ(8)に対する風の入射角が変化することによって、前記垂直軸風力発電装置の回転速度を安定させる効果を持つとともに、
前記特殊部(7)を前記特殊金属板(10)で接続することにより、それぞれの前記外側フラップ(8)の対応する前記内側フラップ(2)に対する傾斜角度を同一とする、ことを特徴とする垂直軸型風力発電装置。 - 構造物を支持する軸(1)の、発電装置(18)を備えた上部ポイント、および、前記軸(1)下部の軸受台(5)で、前記内側フラップ(2)および前記外側フラップ(8)を支え、
前記内側フラップ(2)の回転は直接前記発電装置(18)に伝達され、
前記内側フラップ(2)および前記外側フラップ(8)による前記軸(1)への負荷は左右対称であり、前記軸(1)は前記構造物を安定に支持することを特徴とする請求項1に記載の垂直軸型風力発電装置。 - 前記外側フラップ(8)に対する風の入射角は前記バネ(12)の張力により調整され、
前記内側フラップ(2)および前記外側フラップ(8)の数がそれぞれ3、4、または5であることを特徴とする請求項1に記載の垂直軸型風力発電装置。 - 前記内側フラップ(2)および前記外側フラップ(8)の数がそれぞれ3であることを特徴とする請求項3に記載の垂直軸型風力発電装置。
