The invention provides a buoy structure for an amphibious aircraft. The buoy structure comprises a buoy (1), a supporting rod (2), a communicating device (3) and a plurality of breather pipes (4), thenumber of the ports of the communicating device (3) is one more than that of the sub-cabins of the buoy (1); the communicating device (3) is arranged in one sub-cabin in the buoy (1), the inner cabins, without the communicating device (3), in the buoy (1) are respectively connected to one port of the communicating device (3) through a breather pipe (4), and the inner cabins provided with the communicating device (3) are communicated with the atmosphere through a breather pipe (4) arranged in the supporting rod (2). The connecting structure is simple in form, the watertight compartments of thefloat bowl are communicated only through the breather pipe, the buoyancy providing capacity of the whole float bowl is reserved, the problem that the float bowl can bear pressurization loads due to different use environments is solved, and the service life of the whole float bowl is guaranteed.

    本发明提供一种用于水陆两栖飞机的浮筒结构,包括:浮筒(1)、撑杆(2)、连通装置(3)和多个通气管(4);所述连通装置(3)的端口数量比所述浮筒(1)的分舱数量多1;所述连通装置(3)设置在所述浮筒(1)内的一个分舱内,所述浮筒(1)内的未设置有所述连通装置(3)的内舱分别通过一根通气管(4)连接在所述连通装置(3)的一个端口上,所述设置有连通装置(3)的内舱还通过一根设置在所述撑杆(2)内的通气管(4)连通大气。连接结构形式简单,仅通过通气管将浮筒的水密舱连通,不仅保留整个浮筒提供浮力的能力,又解决了浮筒因不同使用环境下可能承受增压载荷的问题,使整个浮筒的寿命得到保证。
