Description

technical field [0001] The invention relates to the technical field of ocean energy power generation, in particular to a wave energy collection device for vortex-induced piezoelectric and four-bar stretched dielectric elastic body deformation power generation. Background technique [0002] my country's sea area is vast, and marine disasters such as coastal typhoons and storm surges occur frequently and cause great harm. With the development of marine economy from offshore to open ocean, it is urgent to build a three-dimensional monitoring network for the marine environment to provide fixed-point, continuous, accurate, real-time, and fine-grained data at sea. On-site observation data provide services for marine environment monitoring, disaster warning and emergency response, maritime rights protection and security, etc. The role of marine monitoring equipment is more prominent. The marine monitoring sensor network requires continuous and long-term power supply. The power gener...
