The lower end of the floating island 7 is provided with an air bag 8, and the bottom of the floating island 7 is provided with an air filling hole 15 connected with the air bag 8. The buoyancy is adjusted by adjusting the amount of gas in the air bag 8, and the volume of the floating island 7 immersed in water is changed, so that the sunbathing platform on the top of the floating island 7 is located above the water surface. Hooks are symmetrically arranged on the air bag 8 and the floating island 7 along the circumferential direction, and the air bag 8 is fixed to the floating island 7 by ropes.

[0038] In this embodiment, the floating island 7 is a circularly symmetrical structure similar to a tumbler, and the weight of the floating island 7 is greater than the weight of the cabin body.

[0039] In this embodiment, multiple cabins can be connected and fixed at the top of the floating island 7 at the same time. The multiple cabins can be arranged separately or interconnected. If the multiple cabins are arranged in interconnection, the outermost cabin can remove the board body of the left fixed plate 1, and only retain the frame connected to the middle internal cabin; the inner cabin can remove the board body of the left fixed plate 1 and the board body of the right fixed plate 6 at the same time, retain the frame, or retain the board body of the right fixed plate 6.

[0040] In this embodiment, the top plate 3 is a solar panel, which can utilize solar energy to generate electricity and provide lighting and daily electricity.

[0041] This embodiment combines the cabin and the floating island 7 to realize an amphibious cabin. This embodiment can be easily compressed to the minimum volume for storage and transportation, and can float steadily on the water after unfolding. This embodiment adopts the tumbler technology, the upper cabin body is made of lightweight materials, and the lower floating island 7 is made of heavy glass, so that the center of gravity is lowered, which improves the stability of the floating cabin at sea in wind and waves. In addition, the upper part is a combination of a lightweight aluminum alloy frame and a carbon fiber reinforced composite material plate body, which is light in weight and has a small push-pull load. It does not need to use redundant structures to carry the load together, and only a retractable mechanism 20 is required to achieve it. The side of the floating island 7 uses transparent glass to realize underwater sightseeing functions. The cabin top plate 3 is equipped with a solar panel, which uses the strong light on the sea surface to generate electricity by itself, meet life needs, and provide lighting and electricity for life.
