Abstract

In response to the increasing energy consumption demands of offshore buoy navigation lights

this paper proposes a submerged chain generator capable of simultaneously harnessing wave and tidal energy in the marine environment. The motion and output voltage models of the generator are established

and numerical simulations are conducted to study the effects of component structure and motion parameters on its power generation performance. The stiffness of the springs and the planar excitation array structure in the generator are reasonably determined and experimentally verified. The results show that

under the same wave-current coupled excitation

the motion magnitude of the array decreases with the increase in the stiffness of the springs. The output voltage also increases with the increase in the motion frequency and magnitude of the array. When the swing magnitude and frequency of the anchor chain are 142.70 mm and 0.85 Hz

respectively

the power generation device （array dimensions： length × width × height=50 mm×20 mm × 50 mm） achieves an average voltage magnitude of 5.02 V and a maximum no-load power density of 0.024 mW/cm

enabling the collection and conversion of low-frequency wave and current energy and providing power for offshore buoy navigation lights.
