  • Publication number: 20160169208
    Abstract: In an air-cushioned small hydraulic power generating device, when a stator in a generator linked by means of an upper rotational shaft to a first vertical-shaft windmill rotates in a first direction, a rotor in the generator linked by means of a lower rotational shaft to a second vertical-shaft windmill and an air-cushioned water wheel rotate in a second direction opposite to the first direction, thereby increasing the rotational force and thus enhancing the power generation efficiency. The generator can be easily installed in valleys, watercourses, rivers, irrigation water channels, or seawater channels without having geographic limitation. Furthermore, since an air-cushioned water wheel is used to support the weight of the generator and rotational shafts, the generator can be easily installed to float on the surface of water. Therefore, breakdown and maintenance cost of the generator can be minimized.
