Abstract

The invention discloses a wave energy power generation device and method. Existing wave energy collection equipment is low in power generation efficiency, and a core element is exposed in an externalenvironment. The wave energy power generation device comprises a floater shell, a water tank, a water drainage micropump, a water inlet micropump, piezoelectric beams, a transverse vibration block, afirst rack, a second rack, a third rack, a longitudinal vibration block, a gear, permanent magnetic steel, a first electromagnet, a second electromagnet, a first damping component and pressure sensors. The first rack on the longitudinal vibration block, the second rack on the transverse vibration block and the third rack on the permanent magnetic steel are meshed with the gear. The bottoms of then piezoelectric beams are fixed to the top of the transverse vibration block, and the tops of the piezoelectric beams are fixed to the bottom of the water tank through the pressure sensors. Piezoelectric plates are embedded in the piezoelectric beams. Accordingly, the system inherent frequency is changed by adjusting the water tank weight and mass block vibration resistance composite mode, and then the power generation efficiency is improved.

Description

Technical field [0001] The invention belongs to the technical field of energy recovery and utilization, and particularly relates to a wave energy power generation device and a power generation method thereof. Background technique [0002] Nowadays, regarding the unlimited demand of energy, many researches are focused on energy harvesting. The main purpose of these studies is to generate useful energy from wasted energy. Ocean wave energy is one of the huge energy sources, and its energy density is higher than some renewable resources such as solar energy and wind energy. However, most of the wave energy in life is not used but wasted. Due to the low frequency of ocean waves, less attention is paid to obtaining vibration-based energy from this energy resource. [0003] Marine exploration equipment, such as buoys, generally work for a long time without being on duty. The working life of battery-powered equipment is limited by the power of the battery, and the working life is relat...
