Description

Technical Field

[0001] This utility model relates to the field of amphibious unmanned surface vessel technology, specifically a folding wing type sail amphibious unmanned surface vessel. Background Technology

[0002] Since the beginning of the 21st century, the demand for unmanned surface vessels (USVs) has grown exponentially for missions such as marine scientific research, maritime search and rescue, and border patrol. For example, long-term marine environmental monitoring (such as typhoon tracking and red tide early warning) requires equipment capable of continuous operation for months or even years. Traditional fuel-powered USVs are limited by fuel tank capacity, resulting in high costs for frequent refueling; pure battery power faces energy density bottlenecks, and the disposal of used batteries may exacerbate marine pollution. Meanwhile, the International Maritime Organization's (IMO) strict restrictions on ship carbon emissions (such as a 40% reduction in global ship carbon intensity by 2023) further compels the application of clean energy technologies. With the rapid growth in global marine resource development, environmental monitoring, and national defense security needs, USVs, as efficient and flexible marine operational platforms, have become a key focus of modern marine technology development. However, traditional USVs generally rely on fuel or battery power systems, which suffer from limited endurance, high operating costs, and significant carbon emissions. Therefore, improvements to existing technologies are necessary. Utility Model Content
