Title:
IMPELLER ASSEMBLY FOR HYDROELECTRIC POWER GENERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/209537
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an impeller assembly for a hydroelectric power generation device, wherein the configuration of a water inlet and the configuration of an impeller are actively improved such that the potential energy of water and the pressure of the flow rate thereof are simultaneously provided to the impeller so as to rotate same in a high-efficiency state and to provide a strong output, thereby maximizing the output efficiency. Particularly, the present invention relates to an impeller assembly for a hydroelectric power generator, wherein an impeller is contained in a cylindrical body having a containing space formed therein and sealed by a cover member, a driving shaft is supported by a bearing coupled to the cover member, and the body has an inlet and an outlet formed therein such that the impeller installed in the inner space is driven. The inlet is configured to be able to supply a fluid, as if an involute curve, from the 12 o'clock direction of the body to the 4 o'clock direction thereof. The outlet is formed from the 6 o'clock direction to the 8 o'clock direction. The impeller has multiple fluid tanks formed to be open toward the inner surface of the body. A pressing portion is formed from the 4 o'clock direction to the 6 o'clock direction between the inlet and the outlet so as to close the fluid tanks, thereby increasing the rotational moment of the impeller.
