Abstract

The invention discloses a piezoelectric flexible plate wave energy generating device. Both ends are provided with piles; each pile is internally provided with an energy storage device; and the pile isconnected with the piezoelectric flexible plate through a hinge device. The wave motion can be directly converted to a mechanical motion of a flexible piezoelectric material, an intermediate transmission link is reduced, the damping force caused by energy transfer and conversion is reduced to a minimum degree, and as the piezoelectric material is quick in response and high in sensitivity, a pointwith small elastic deformation amplitude in the flexible plate can also be subjected to energy conversion, surface-type conversion on continuous elastic deformation mechanical energy of the flexibleplate can be realized on the basis, and the wave energy-to-electric energy conversion efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of ocean wave power generation, and in particular relates to a piezoelectric flexible plate wave power generation device. Background technique [0002] The price of traditional fossil energy such as coal and oil is becoming increasingly scarce, and energy shortage has become a common problem facing the world today. At the same time, the international community is increasingly concerned about issues such as climate change and environmental protection, making it urgent to find alternative energy sources. The ocean, which accounts for more than 70% of the earth's surface, contains huge energy. Accelerating the development and utilization of ocean energy has become a common consensus among coastal countries and regions in the world. Among them, wave energy is becoming increasingly popular all over the world due to its renewable, green, and abundant reserves. The attention of all countries, the scientific and lar...
