SMALL HYDROELECTRIC POWER GENERATION DEVICE INSTALLED UNDERWATER

WIPO Patent Application WO/2018/124335

A1

The present invention relates to a small hydroelectric power generation device installed underwater and, more particularly, to a small hydroelectric power generation device installed underwater, wherein the device is connected to a platform floating on a water surface, an impeller is installed inside a submerged tube that is submerged underwater, the impeller is rotated by a flow pressure of a fluid that passes through the submerged tube, thereby driving a generator, and electric energy is accordingly generated. The technical gist of the present invention described above is a small hydroelectric power generation device installed underwater, comprising: a platform floating on a water surface; a submerged tube connected to the platform and submerged in water; an impeller installed inside the submerged tube and rotated by a flow pressure of a fluid occurring underwater; and a generator connected to the impeller outside the submerged tube so as to generate electricity by means of rotational force of the impeller, wherein the impeller comprises an upper boss having the shape of a disk that is convex upward, a driving shaft of the generator being connected to the upper boss; a lower boss having the shape of a disk that is convex downward, the lower boss being shaft-supported on the submerged tube; and a plurality of blades formed in wing shapes, the blades connecting peripheries of the upper and lower bosses at a predetermined interval in curved shapes.
