AIR-CUSHIONED SMALL HYDRAULIC POWER GENERATING DEVICE

摘要

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.

主权项

1. An air-cushioned small hydraulic power generating device, comprising:
a generator with an upper rotational shaft and a lower rotational shaft; a first vertical-shaft windmill that is linked to an end of the upper rotational shaft by means of a first coupler to rotate the upper rotational shaft; a second vertical-shaft windmill that is linked to an end of the lower rotational shaft by means of a second coupler to rotate the lower rotational shaft; an air-cushioned water wheel that is vertically linked to a lower portion of the second vertical-shaft windmill by means of the second coupler, thereby being enabled to float on the surface of water and rotated by a resistance of water current while supporting the upper rotational shaft and the lower rotational shaft and being rotated by resistance of a water current; and a water current guiding means that is installed on a wall by means of a fixed rail and guides a water current such that the air-cushioned water wheel flows fast in one direction.
