Problems solved by technology

First of all, most of the small wave energy harvesting devices currently appearing are three-stage conversion processes, that is, using mechanical structures to convert the up and down motion of waves into the rotational motion of generators. Due to the existence of intermediate conversion devices, the energy collection efficiency is low
Secondly, most of the current wave energy generation systems for navigation lights are autonomous systems, which cannot achieve maximum wave energy tracking according to changes in water areas
[0003] At present, there are many offshore equipment, such as buoy lights, water detectors, etc., but most of them have energy supply problems, that is, charging multiple times at one time or replacing the power supply, resulting in waste of human and material resources. At present, there have been various energy supplements for buoy lights Solutions, such as the use of solar energy, wind energy, etc., but solar energy is limited by the sun, climate, etc., and th
