AI Technical Summary

Technical Problem

Small-scale hydroelectric power generation systems face instability due to variable water flow volumes and speeds, preventing consistent electricity production.

Method used

A small hydroelectric power generation device with parallel cylindrical portions, a water branching mechanism, and an air movement passage that uses air flow to generate electricity, independent of water flow volume or speed, utilizing spring water or sewage water.

Benefits of technology

The device generates stable electricity by alternating water supply to cylindrical portions, leveraging air flow for consistent power generation, even with fluctuating water sources.

Abstract

To provide a small hydroelectric power generating device capable of stably generating electricity by utilizing a small water flow. [Solution] The device comprises a first cylindrical portion 10 and a second cylindrical portion 20 arranged in parallel, a water branching portion 30 that alternately supplies water from a water source to the first cylindrical portion 10 and the second cylindrical portion 20, a moving member 40 that is within the first cylindrical portion 10 and the second cylindrical portion 20 and is positioned between the water supplied to the first cylindrical portion 10 and the second cylindrical portion 20 from the water branching portion 30 and the air present within the first cylindrical portion 10 and the second cylindrical portion, an air movement passage 50 that, when the moving member 40 within the first cylindrical portion 10 descends, causes the air below the moving member to move toward the second cylindrical portion 20, and when the moving member 40 within the second cylindrical portion 20 descends, causes the air below the moving member to move toward the first cylindrical portion 10, and a power generation mechanism that generates power using the movement of air moving through the air movement passage.
