Description

Small Hydro Power Generation Turbine The present invention relates to a small hydropower turbine. With the recent increase in demand for eco-friendly and sustainable energy sources, hydropower is gaining prominence as one of the major renewable energy sources. Small-scale hydropower systems do not require infrastructure such as large-scale dams and can generate electricity by utilizing natural rivers or waterways. As part of these small-scale hydropower technologies, small hydropower turbines can generate electricity using the energy of water flow with a relatively simple structure, making them effective for use in rural areas or regions not connected to the power grid. However, existing small hydropower turbine designs suffer from problems such as failing to make efficient contact with the water flow or achieving optimal performance only under constant flow rates or conditions. There is a need for a small hydropower turbine design that can solve these issues and generate electricity with high efficiency in various environments. FIG. 1 is a drawing illustrating a small hydroelectric turbine according to an embodiment installed in a waterway, FIG. 2 is a drawing illustrating a small hydroelectric turbine of an embodiment installed in a river, FIG. 3 is a detailed perspective view of a small hydroelectric turbine according to one embodiment, FIG. 4 is a drawing showing the wing portion viewed from the axial direction of the shaft. FIG. 5 is a side cross-sectional view showing the interior of the column of the wing portion, FIG. 6 is a drawing illustrating the wing of the wing portion, Figure 7 is a diagram illustrating the rotation process of the wing section. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings.
