Abstract

一种微小型水轮机，金属机壳的上面有盖板、进水管、机壳、尾水管共同组成封闭式连通体结构，进水管口处水头的势能几乎全部作用于叶轮上，效率比敞开式机壳的水轮机提高10％左右，且无需构筑拦坝、水槽等水工建筑，只要0.7米以上水头将地脚固定便可使用，造价较低、安装方便、特别适用于农村山区单家独户用于发电、碾米、抽水等。

Description

本实用新型涉及一种水轮机，特别是一种低水头微小型水轮机，用于带动微小型发电机、碾米机、抽水机等机械。
公知的低水头微小型水轮机由主轴、叶轮、机壳和尾水管组成，机壳用金属或水泥做成，上面是敞开的，因而不能利用水流的全部势能，效率较低；同时安装时必须构筑拦坝、水槽等工程量较大的水工建筑，总造价较高且安装不方便，这是其缺点。
本实用新型的任务是提供这样一种微小型水轮机，效率较高，总造价较低且安装方便。
本实用新型的任务是用如下方式实现的：在金属机壳的上面加密封板，将机壳封闭即不敞开，并用封闭式的进水管与机壳和尾水管一起组成一个封闭式连通整体，即除进水管口和尾水管口供水流进出外，整个系统是封闭的，水流不能进出。这样，只要有足够的水量，水头的势能几乎全部作用到叶轮上，从而可提高效率10％左右，只要0.7米水头便可用于发电，由于整机组成了封闭式连通整体，无须构筑拦坝、水槽等水工建筑，只需将机壳上的地脚固定即可，因而总造价降低，安装较方便，这是本实用新型的优点。
下面结合附图对本实用新型作进一步的描述：
参见附图：（1）为进水管；（2）为机壳；（3）为主轴；（4）为导流盘；（5）为叶轮；（6）为尾水管；（7）为密封板。
如图所示：机壳（2）上面有密封板（7）而不敞开，进水管（1）、机壳（2）和尾水管（6）组成为一个封闭式连通体结构。即除了进水管口和尾水管口供水流进出外，整个系统对水流是封闭的，这样，只要流量足够大，进水管（1）进口处的水头压力几乎全部作用到叶轮（5）上。由于整机成为一个整体，可在机壳（2）上装上机架或地脚安装孔，而无须构筑拦坝、水槽等水工建筑，造价较低、安装较方便，特别适用于有小水流的山区单家独户使用。
