Abstract

A hydroelectric generation device comprises a base, a rotation module, a coupling module and a power generating module. The base has two side walls that are immersed into water. The rotation module includes a rotary rack and four blades. The rotary rack has a central shaft combined to the two side walls in a rotating manner. A first support rack and a second support rack are respectively fastened at two ends near the central axle. The four blades are circularly arranged between the first support rack and the second support rack in equal spaces. Each blade has a rotary shaft capable of being combined at the first support rack and the second support rack in rotating manner. The coupling module includes a central wheel, four coupling wheels and two coupling belts. The central wheel is fastened to the side wall and is passed by the central shaft. The four coupling wheels are respectively fastened to an end of the four rotary shafts. Each coupling belt is respectively wound to the central wheel and two adjacent coupling wheels. When the rotary rack rotates, the two coupling belts can link the four coupling wheels to rotate to drive the corresponding blades that rotate at the optimum angle facing water flow. The central wheel and the coupling wheels are allocated that the central wheel rotates a circle relative to the rotary rack while the coupling wheels rotate a semi-circle. The power generation module is disposed at the base and connected to the central shaft to convert the rotation power into electric power. With the foregoing structures, the invention has efficiencies of effectively converting hydraulic power into electric power and simple structure assembly and low costs.
