Description

沐汐叶轮环
技术领域
本发明涉及一种内径侧嵌固有叶轮桨叶的环体构件，一种可以产生类似螺旋桨功能效果的沐汐叶轮环。
背景技术
目前，公知的螺旋桨已经广泛地应用于各行业中，包括各类型的离心泵、电器中的散热风扇、水中行驶的各类船舶、空中飞行的各类飞行器、风力和水力发电机等等都用到了螺旋桨，其主要样式为中间又一根主轴，主轴周圈分布叶轮桨叶。现有螺旋桨的技术特点是：主轴转动带动周圈桨叶对气体或液体介质产生推力和离心力，反之运动的气体或液体介质反作用于螺旋桨叶，可以使得螺旋桨叶带动中间的主轴转动并产生动能，根据螺旋桨的技术进而衍生出离心泵、电风扇、风力和水力发电机等等产品。但现有的螺旋桨的技术特点也决定了必须有主轴关联带动桨叶运动，桨叶与介质直接接触，主轴也必须伸入介质中，但在某些空间中是无法放置并使用螺旋桨的，例如在类似于密封的直线管道中，螺旋桨是不便伸入直线管道中使用的。
发明内容
为了克服上述现有技术的不足，本发明提供了一种沐汐叶轮环。沐汐叶轮环是一种内径侧嵌固有叶轮桨叶的环体构件，叶轮桨叶分布固定在环体内径侧壁上，而不是分布固定在中间的主轴上。
本发明所采用的技术方案是：沐汐叶轮环是一种内径侧嵌固有叶轮桨叶的环体构件，将叶轮桨叶分布环体内径侧壁上，叶轮桨叶根部宽，端部窄，桨叶长度L小于内径半径R，桨叶宜为凹凸曲面结构形式，桨叶根部与内壁成倾斜角度固定连接，倾斜角度为0~60度；沐汐叶轮环外径侧为连接转动的接触面，接触面可制成齿轮、凸齿牙、凹槽等截面形状，对应用于齿轮、链条、皮带等连接方式；沐汐叶轮环两侧为连接轴承和密封系统的延伸段，延伸段可通过轴承和密封系统与外体结构连接。
与现有螺旋桨相比，本发明的有益效果是：取消螺旋桨中间的主轴结构，将叶轮桨叶分布固定在环体内径侧，沐汐叶轮环可以对接应用于密封的直线管道环境中，或者在某些环境下取代现有螺旋桨使用，以便达到更好的作用效果。

图12是内径侧八桨叶沐汐叶轮环示意图
具体实施方式是：沐汐叶轮环通过轴承和密封系统与外体结构连接后，可以实现沐汐叶轮环相对于外体结构的转动运动，在借助外力带动沐汐叶轮环整体转动的情况下，转动运动的沐汐叶轮环内径侧桨叶对气体或液体介质产生了相互作用力，从而推动外体结构运动或者加速介质运动，例如将沐汐叶轮环连接在船舶或者飞行器上，可以推动船舶或飞行器运动，或者将沐汐叶轮环通过外体结构两侧直接对接上直线管道，可以加速直线管道中的介质运动。反之，运动的气体或液体介质反作用于沐汐叶轮环桨叶时，可以使得沐汐叶轮环桨叶带动沐汐叶轮环环体转动并产生动能，例如可将沐汐叶轮环应用于风力和水力发电装置中，借助风力或水力作用于沐汐叶轮环上带动发电机发电。沐汐叶轮环的加工制作可以分为整体制作，或者分体制作再组合的方式，具体就是小直径的沐汐叶轮环通过模具加工整体成型，大直径的沐汐叶轮环可以将环体、桨叶、延伸段分别制作后，再焊接组合成一个完整的沐汐叶轮环。
