Retractable blade vertical-axis tidal turbine

Abstract

The invention discloses a retractable blade vertical-axis tidal turbine, which comprises a rotating shaft, a turntable, blades, retractable support arms, eight guide rails, guide rail wheels, baffle plates, a controller and a support part, wherein the guide rails are positioned in the turntable, and are divided into two layers, and each layer comprises four guide rails; the guide rails are uniformly welded on the rotating shaft at intervals of 90 degrees; the guide rail wheels are mounted on the inner surfaces of the guide rails; a retractable support arm is mounted in each guide rail; the support arms are retractably and movably connected with the guide rails through the guide rail wheels; the blades are mounted at the ends, far away from the turntable, of the support arms; the blades are rectangular, and are positioned on the same planes as the upper and lower layers of retractable support arms; the baffle plates are fixedly mounted at the ends, far away from the turntable, of the blades, and are in right-angled connection with the blades; the blades slide in the guide rails through the retractable support arms, and are controlled by the controller to retractably move. According to the retractable blade vertical-axis tidal turbine with such a retractable design, the energy yielding efficiency of the vertical-axis turbine is improved, the size of the whole device is reduced, convenience in transportation and considerable market prospect are achieved, and the submarine mounting cost is reduced.
本发明公开了一种伸缩式叶片竖轴潮流能水轮机,包括转轴、转盘、叶片、可伸缩支臂、导轨、导轨轮、挡板、控制器、支撑件,导轨位于转盘的内部,总共八个,分为两层,每层四个,每个导轨间隔90度均匀焊接在转轴上,导轨轮安装在导轨内表面,每个导轨内安装一个可伸缩支臂,支臂通过导轨轮与导轨实现可伸缩的活动连接,支臂的远转盘端安装叶片,叶片为矩形,与上下两层可伸缩支臂位于同一平面,叶片的远转盘端固定安装挡板,挡板与叶片呈直角连接,叶片通过可伸缩支臂在导轨中的滑动,在控制器的控制下,实现伸缩运动。这种可伸缩的设计提高了竖轴水轮机的获能效率,缩小了整个装置的体积,方便运输,减少了海底安装成本,具有可观的市场前景。
