本發明係有關於一種水力發電系統,尤其是指一種在具有傾斜角度之滾筒內部焊接複數個螺旋式葉片並結合水流之動能與位能來提升發電效率的水力發電系統。The present invention relates to a hydropower generation system, and in particular, to a hydropower generation system in which a plurality of spiral blades are welded inside a drum with an inclined angle and combine the kinetic energy and potential energy of water flow to improve power generation efficiency.
按,螺旋式水輪機是一種適用於溝渠發電的小型水流發電機,因為其內建的螺旋葉片形狀複雜,使經過的流體可以在較短的行程中獲得較大的扭力而產生較高速的轉速,進而獲得更好的發電效率;然而,一般的螺旋式水輪機是屬於開放式的結構,無法有效地且完全地引導溝渠中的水流與螺旋葉片直接作用,而讓整體的發電效率無法再進一步提升,且其外螺旋葉片在水輪機旋轉時會造成漏水現象,不僅減緩了螺旋葉片的旋轉速度,也進一步降低了發電的效率;因此,如何藉由創新的硬體設計,有效防止溝渠中的水流流經螺旋葉片而導致的漏水問題,且可使用較少的零件而達到容易安裝與維修之目的,進而有效提升水力發電機之發電效率,是水力發電機等相關產業的開發業者與相關研究人員需持續努力克服與解決之課題。According to the press, the spiral turbine is a small water flow generator suitable for ditch power generation.
