The invention discloses an ocean buoy utilizing wave energy and solar energy to generate electricity, which comprises a shell and a piezoelectric energy harvesting mechanism, a sensor is arranged in the shell, the shell is of a polyhedral structure, a solar panel is laid outside the shell, and two ends of the piezoelectric energy harvesting mechanism are fixed in the shell; the piezoelectric energy harvesting mechanism comprises a support, a plurality of circular ring shells are evenly arranged on the support, the circular ring shells are located in the outer shell through the support, and piezoelectric ceramic pieces are arranged on the circular ring shells. The circular ring shells vibrate and deform on the support under the action of sea waves, and the piezoelectric ceramic pieces are driven to deform to generate electric energy. The solar panel converts solar energy into electric energy to supply power to the sensor. The piezoelectric energy capturing mechanism and the solar panel are arranged at the same time to capture energy of sea waves and solar energy, energy in the nature is fully utilized, the electric quantity is large, and all-day and sustainable power supply is achieved; meanwhile, the structure is easy to miniaturize, the manufacturing cost is low, manual battery replacement is avoided, and the operation and maintenance cost is reduced.
本发明公开了一种利用波浪能和太阳能发电的海洋浮标,包括外壳和压电俘能机构,外壳内设有传感器,外壳为多面体结构,外壳外铺设有太阳能板,压电俘能机构两端固定在外壳内;压电俘能机构包括支架,支架上均匀设有多个圆环壳体,圆环壳体通过支架位于外壳内,圆环壳体上设有压电陶瓷片;圆环壳体在海浪波的作用下在支架上振动发生形变,带动压电陶瓷片发生形变产生电能;太阳能板将太阳能转化成电能,给传感器供电。本发明通过同时设置压电俘能机构和太阳能板俘获海波浪的能量和太阳能,充分利用自然界中的能量、电量大,实现全天、可持续性的供电;同时结构易于小型化、制造成本低,避免人力更换电池降低运维成本。
