APPARATUS FOR OCEAN HYBRID HARVESTING USING PIEZOELECTRIC

摘要

PURPOSE: An offshore hybrid harvesting apparatus using piezoelectricity is provided to easily convert the vertical vibration energy of waves generated by a first piezoelectric harvesting module and wind power energy generated by a second piezoelectric harvesting module to electric energy. CONSTITUTION: An offshore hybrid harvesting apparatus using piezoelectricity comprises a first piezoelectric harvesting module (102) and a second piezoelectric harvesting module. The first piezoelectric harvesting module has a piezoelectric plate (130) to convert the vertical vibration energy of waves to electric energy. The second piezoelectric harvesting module is coupled to the first piezoelectric harvesting module and converts wind power energy to the electric energy. The second piezoelectric harvesting module comprises a flat part (140), a central shaft (150), a first blade part (151), a rotary shaft (160), and a second blade part (170). The flat part comprises an upper flat part and a lower flat part. One end of the rotary shaft is contacted to the upper flat part, and the other end thereof is contacted to the lower flat part. The central shaft is formed on the outer circumference of the rotary shaft. The first blade part is coupled to the central shaft. The second blade part is coupled to the upper and lower flat parts and generates the electricity while being repeatedly deformed and restored by contacting to the first blade part during the rotation of the rotary shaft.
