1results about How to "Improve wind energy utilization efficiency" patented technology

This utility model belongs to the field of amphibious unmanned surface vessels (USVs), specifically relating to a folding airfoil sail amphibious USV. It includes a base, with a hydraulic telescopic rod at the upper end of the base, a mast at the upper end of the hydraulic telescopic rod, an upper sail on the upper outer side of the mast, a lower sail on the lower outer side of the mast, and a stepper motor at the upper end of the mast. This utility model features a unique folding mechanism, allowing the sail to be folded and stored when not in use. This not only improves the portability and storage efficiency of the equipment but also reduces wind and water resistance in adverse weather conditions or when underwater operations are required, lowering the risk of equipment damage. Using a symmetrical airfoil sail maintains good aerodynamic performance under different wind directions and angles, providing stable and continuous aerodynamic propulsion. This design not only improves wind energy utilization efficiency but also enhances the USV's adaptability to complex and changing environmental conditions.
