In addition, the internal cavity of the balancing compartment is completely sealed under the action of the sea surface seal, which can form air damping, generate resistance against overturning, and force the hull to right itself; when the device is on the sea surface, if the hull is overturned and turned upside down due to severe wind or waves, during the overturning process, one side of the balancing compartment will first scoop water downwards and then be filled with water upwards, that is, one side of the balancing compartment is full of water and the other side of the balancing compartment is empty. At this time, the full water will generate a downward force arm, causing the hull to tip to one side. At the same time, the cargo box moves from high to low, releasing potential energy, causing the hull to tip faster, thereby completing the righting in one go.
[0014] The device combines an arched top cover with a boat-shaped bottom shell to provide a huge storage space. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, the internal cavity 21 of the balancing compartment 10 is completely sealed under the action of the sea surface seal, which can form air damping, generate resistance to overturning, and force the hull to right itself. When the device is on the sea surface, if it encounters severe wind or waves that cause the hull to roll over and turn upside down, during the rollover process, one side of the balancing compartment 10 will first scoop water downwards and then fill it with water upwards, that is, one side of the balancing compartment 10 is full of water and the other side of the balancing compartment 10 is empty. At this time, the filled water will generate a downward force arm, causing the hull to tip to one side. At the same time, the cargo box 13 moves from a high place to a low place, releasing potential energy, causing the hull to tip faster, thereby completing the righting in one go. Therefore, the device can cooperate with airdrops to achieve rapid sea rescue, and can use the balancing compartment 10 to resist severe sea conditions and prevent rollover.
