Sažetak
In this work a miniaturized underwater hydro generator concept is proposed for powering wireless sensor network nodes. It is based on a small DC generator encapsulated in a watertight enclosure and a propeller driven by river flow. Management electronics is designed to regulate the obtained electrical energy and store it on a super capacitor. For determining the propeller shape, a rough verification of turbine blades performances via numerical analysis is performed. Based on these calculations, two propeller variants are used in the experiments. The assembly of the hydro generator is whence tested in real river flow conditions. Based on the performed preliminary measurements, the design of the turbine is optimised and a further set of measurements is carried out in a flow tunnel. The generated power of roughly 700 mW, corresponding to the calculated value, is obtained, while the output powers are up to 220 mW.
