Simulation Optimization of Offshore Warning Marker Tracking Device Based on Multidimensional Wave Energy Utilization

To address the issues of low positioning accuracy and poor endurance in Marine environment, this paper designs an offshore wave energy-powered warning marker tracking device. The performance of device is validated through theoretical modeling and Multiphysics simulations. COMSOL software is used for fluid-structure interaction analysis of turbine blade flow fields, we found that inner-vortex aluminum alloy blades combined with turbulence effects increase the fluid tangential velocity to 1.5 times that of a non-turbulent system, improving mechanical energy conversion efficiency by 30%. By integrating phase control and resonance matching technologies, the device achieves a single-unit power density of 4.2 kW/m under conditions of 2.94 m wave height and 75° incident angle, with a theoretical wave energy utilization rate of 31.5%. Structural strength simulations reveal a maximum Von-Mises stress of 3.0×10⁴ Pa, well below the material yield strength (250 MPa). Nano-ceramic coatings reduce corrosion rates to 0.005 mm/year, and a thermal control system limits internal temperature fluctuations to ±5°C. The results validate the advantages of device in efficient wave energy conversion, structural reliability, and environmental adaptability, offering a green and cost-effective solution for maritime search rescue and reef warning applications.
