Problems solved by technology
When the existing piezoelectric effect power generation equipment is installed on the beach, it is easy to change its position when it is impacted by waves, so that the piezoelectric power generation piece cannot well receive the piezoelectricity generated by the waves for power generation, and the utilization rate of the wave pressure Not high, low power generation efficiency, in addition, due to long-term seawater erosion, the surface material of the piezoelectric power generation sheet will be corroded and damaged, lose the pressure power generation function, and have a short service life

Description
technical field [0001] The invention relates to a power supply system based on ocean wave power generation, in particular to a power generation device, power generation system and power supply system based on piezoelectric effect. Background technique [0002] In recent years, countries around the world are vigorously developing various renewable energy sources such as solar energy, wind power, and tides, and environmental energy recovery technology has attracted more and more attention from people. Traditional green energy power generation methods include solar power generation, wind power generation, photovoltaic power generation and other natural energy generation without pollution. However, the above-mentioned power generation methods have high requirements for site selection, and the power generation is small and the volume is large, which makes maintenance inconvenient. In 1880, the Curie brothers discovered the piezoelectric effect on α-quartz crystals while studying ...
