Abstract

【課題】波力発電は、波の大小の変化が天気や風よりも穏やかで、且つ、予測し易いこと、２４時間発電可能なこと、外洋に面した海岸では波の小さい時はあっても、”無波”という状態が存在せず、最低限の波を確保できることなど、安定した自然エネルギーと言える。しかし、現在まで波のエネルギーを効率良く取り出す方法の発明はあまり進んでおらず、小規模で効率のよい発電装置を提供する。
【解決手段】外洋に面して、５０ｃｍ以上の高さの波が押し寄せるような海岸に設置して、波を効率良く集め、そのエネルギーによって発電機を回し、発電する方法を考案した。集波板と発電タブからなる小型で高剛性を有し、移動と設置が簡易な発電装置であり、数十キロワット／時以下の小規模な発電を担うと共に、より最適な設置場所、設置方法、保守性能と耐久性の研究開発を行うのにも適している。
【選択図】図１[PROBLEMS] Wave power generation is such that the change in the magnitude of the wave is gentler than the weather and wind and is easy to predict, that it can generate power for 24 hours, even if the waves are small on the coast facing the open ocean. It can be said that it is stable natural energy because there is no state of “no wave” and the minimum wave can be secured. However, the invention of a method for efficiently extracting wave energy has not progressed so far, and a small-scale and efficient power generation apparatus is provided.
A method has been devised, which is installed on the coast facing the open ocean where waves of 50 cm or higher are gathered, efficiently collecting the waves, turning the generator by the energy, and generating electricity. It is a small and highly rigid power generation device consisting of a current collecting plate and a power generation tab, and is easy to move and install. It is responsible for small-scale power generation of several tens of kilowatts per hour and more optimal installation location and installation method. Also suitable for research and development of maintenance performance and durability.
