Description

technical field [0001] The invention belongs to the technical field of ocean energy generating devices, and relates to an oscillating float type wave energy generating device based on a dielectric elastic body. Background technique [0002] Ocean energy, represented by wave energy, is considered by the industry as an ideal clean and renewable energy source, and thus has attracted more and more attention from various countries. In recent years, scientists from various countries have focused on the large-scale development and commercial application of ocean energy generators, and built offshore power generation platforms with large structural scale and high power generation efficiency, and small power generation devices that continuously supply power to wireless sensor nodes and low-power equipment on the sea surface. But very few. [0003] At present, the research reports on offshore power generation devices in the prior art include: [0004] CN106949001A discloses a sinkin...

[0010] The above-mentioned prior art further proves that it is feasible to use dielectric elastomers in power generation devices. However, the use of dielectric elastomers in offshore power generation devices has not been reported yet, and offshore power generation has become a new direction for the development of international wind power. Therefore, it has become a new direction for researchers in this field to study a device that uses dielectric elastomers for wave energy generation.
