Description

Portable Micro-Hydro-Proofwer Generation Apparatus The present invention relates to a portable small hydropower generation device. Recently, as the global need for eco-friendly energy has increased, the development of renewable energy technologies capable of replacing fossil fuels is actively underway. Among these, hydroelectric power has the advantage of providing a relatively stable and continuous power supply compared to solar or wind power. However, existing hydroelectric power facilities are mostly constructed as large-scale power plants, which presents problems such as high installation costs, long construction periods, and limited installation sites. Accordingly, micro-hydropower technology—small-scale hydroelectric power systems capable of generating electricity even with low head and flow rates in places such as rivers, agricultural waterways, mountain valleys, and campsites—is attracting attention. However, most micro-hydropower devices currently on the market or under research are stationary, which presents disadvantages such as cumbersome installation and removal, difficulty in transportation, and inconvenient maintenance. In addition, existing small hydropower devices require increasing the rotational speed of the turbine to improve power generation efficiency, but this causes pressure loss and vibration problems in the inflow water, leading to frequent breakdowns. Moreover, there are extremely limited portable power generation devices that can be used outdoors or in emergency situations, and their power generation performance remains at a very low level.
