Abstract

本实用新型涉及一种水轮机，特别涉及一种曲面叶片式水轮机。本实用新型提出了一种可以用于极低水头下的曲面叶片式水轮机。其技术方案是：一种曲面叶片式水轮机，包括转轴和叶片，转轴外设有外壳，叶片垂直于曲面叶片式水轮机的轴心线安装于外壳上，叶片为曲面结构，曲面弯度为45°，叶片数量为8片，等间距固定在外壳上，叶片弦长为0.13m，叶宽为0.3m。本实用新型可以在低水头差ΔH＝1.5m～2.0m下运行，减小了波能发电装置对水头的要求。

Description

曲面叶片式水轮机
技术领域
本实用新型涉及一种水轮机，特别涉及一种曲面叶片式水轮机。
背景技术
水轮机将水流的能量转换为轴的旋转机械能，能量转换时借助转轮叶片与水流相互作用来实现的。根据转轮内水流运动的特征和转轮转换水流能量形式的不同，水轮机可以划分为反击式和冲击式两大类。反击式水轮机利用了水流的势能和动能。水流充满整个水轮机的流道，在水流的冲击作用下，水轮机围绕转轴转动，转轴带动发电机做功，产生电能。现有水轮机的工作水头范围为3米到几百米不等，然而对于2米以下的极低水头，现有水轮机难以正常工作。
发明内容
为解决上述技术问题，本实用新型提出了一种可以用于极低水头下的曲面叶片式水轮机。
本实用新型的技术方案是：一种曲面叶片式水轮机，包括转轴2和叶片3，转轴2外设有外壳1，叶片3垂直于曲面叶片式水轮机的轴心线安装于外壳1上，叶片3为曲面结构，曲面弯度为45°，叶片3数量为8片，等间距固定在外壳1上，叶片3弦长为0.13m，叶宽为0.3m。
本实用新型可以在低水头差ΔH＝1.5m～2.0m下运行，减小了波能发电装置对水头的要求。
附图说明
图1是本实用新型的结构示意图；
图2是本实用新型的部分剖面图。
具体实施方式
结合附图具体说明本实用新型。
参见图1，一种曲面叶片式水轮机，包括转轴2和叶片3，转轴2外设有外壳1，叶片3垂直于曲面叶片式水轮机的轴心线安装于外壳1上，叶片3为曲面结构，曲面弯度为45°，叶片3数量为8片，等间距固定在外壳1上，叶片3弦长为0.13m，叶宽为0.3m。
参见图1及图2，本实用新型在工作时，水流由上而下击打在叶片3上，在水流冲击力的作用下，叶片3绕转轴2旋转，从而将水流的势能转换成叶片3的动能。
