Description

一种电能与管内流体动能的转换装置
技术领域
本专利申请涉及电机(含电动机和发电机),尤其涉及一种电能与管内流体动能的转换装置。一个构思中,它的应用领域是低温差环境的自然对流发电。
背景技术
以电动管道轴流泵为例,电动管道轴流泵的习见结构是电动机的转子和定子在管道外部,叶轮在管道内部,通过传动机构将电动机输出的机械能传递给叶轮。该结构需要经常维护。
发明内容
本专利申请的目的在于提供一种电能与管内流体动能的转换装置,可大大减少故障率,降低维护频率。
该目的是这样实现的:一种电能与管内流体动能的转换装置,包含电机和流体机械,电机具有转子和定子,流体机械包含旋转叶片及其转轴;其特征是:转子与旋转叶片相互固装位于管内;定子对应于转子的位置在管外与管道定位安装。
进一步的,旋转叶片转轴与管道之间的轴承是磁悬浮轴承。
进一步的,在旋转叶片的外缘部位固装永磁体而构成转子。
进一步的,定子是可以沿母线拆解的。这样,检修和更换定子的时候不必拆卸管道。而转子部分,因为结构简单并且无润滑无磨损,故障率非常低。
本专利申请的有益效果:本专利申请将旋转叶片稍微改变,使之同时充当转子,宏观上的效果是减少了现有技术的一个必要构件(转子);并且采用磁悬浮轴承,降低了管道内构件的故障率;又沿母线拆解环绕管道的定子,使得排除常见故障变得简便。这使得装置的制造、使用和维护值守的成本大为降低。
附图说明
下面结合附图对实施例详细说明。
图1是实施例的示意图。为简明图面的目的,图中未示出定子;并且,包围图中其余构件的管道仅绘出了局部。
图2在图1基础上隐藏了上方的磁悬浮轴承固装座,以显示磁悬浮轴承的旋转部分的结构。图2中隐藏了永磁体。
图3是下方的磁悬浮轴承固装座。图3中隐藏了永磁体。
图中标记说明:1 管道,2 旋转叶片,3 转轴,4 转子永磁体安装条,41 转子永磁体安装孔位,5磁悬浮轴承固装座,51 轴承转动部永磁体安装孔位,52 轴承固定部永磁体安装孔位。
具体实施方式
下面通过具体实施方式对本专利申请作进一步说明。
如图所示,一种电能与管内流体动能的转换装置,包含电机和流体机械,电机具有转子和定子,流体机械包含旋转叶片2及其转轴3;其特征是:转子与旋转叶片相互固装位于管内;定子对应于转子的位置在管外与管道1定位安装。
旋转叶片2的具体形式不限于图示实施例的螺旋板的形式。其余可选形式比如沿轴向多层分布的倾斜叶片,等等。
进一步的,旋转叶片转轴与管道之间的轴承是磁悬浮轴承。如图所示,实施例的轴承是永磁体磁悬浮轴承。
进一步的,在旋转叶片的外缘部位固装永磁体而构成转子。在图示实施例,转子永磁体通过转子永磁体安装条4与旋转叶片固装。或者(如一个试验样品的形式)转子永磁体直接安装在设于旋转叶片外缘部位的转子永磁体安装孔位41,在该选项下,则不必设置转子永磁体安装条4。
当转子被流体动能驱动旋转,则有旋转磁场切割定子线圈,定子线圈中会形成电流,构成发电机。当外接电源和控制电路使得定子线圈产生旋转磁场,则会带动转子转动,进而驱动流体流动,构成电动泵或者风机。
进一步的,定子是可以沿母线拆解的。这样,检修和更换定子的时候不必拆卸管道。而转子部分,因为结构简单并且无润滑无磨损,故障率非常低。
管道1的材质优选为塑料。
因为有管道1的管壁介于转子与定子之间,使得转子与定子之间的间隙大于习见的电机。但是这在一个低温差环境的自然对流发电的应用构思中(参见图1,另外增加的循环管路布置,使得温差促使流体在管道1内持续向下流动),它不太会降低转换效率;因为摩擦损耗可忽略,当间隙加大,磁力线切割导线的作用较弱,则转子所受到的旋转阻力较小,则流体循环路径的流动阻力较弱,其结果是流速加大,单位时间的流量加大;即是说:虽然转子每转一圈所发出的电量较少,但是单位时间的发电量不太会减少。
有必要在此指出的是以上具体实施例只用于对本专利申请作进一步说明,不代表对本专利申请保护范围的限制。其他人根据本专利申请做出的一些非本质的修改和调整仍属于本专利申请的保护范围。
