The invention belongs to the field of amphibious aircraft fuselage arrangement watertight compartments, and particularly relates to a floor quick-release covering cap meeting the requirements of the watertight compartments. Comprising an opening cover combined structure (1), an opening frame combined structure (2) and a quick-release lock (3), the covering cap combined structure (1) is composed of a honeycomb sandwich structure (11), a first embedded part (12) and a second embedded part (13); the floor quick-release covering cap is arranged on an upper interface of a large closed watertight compartment of a fuselage and is also arranged in a non-pressurized area cabin-penetrating floor operating area, and the floor quick-release covering cap can quickly enter the closed watertight compartment to maintain systems such as an oil tank and the like through a quick-release lock (through first-stage quick release without a special tool); the upper surface of the floor quick-release opening cover is consistent with a peripheral floor (without special convex objects), and the use of an operation space of emergency rescue equipment can be met.
本发明属于两栖飞机机身布置水密舱领域,具体为一种满足水密舱要求的地板快卸口盖。包括:口盖组合结构(1)、口框组合结构(2)及快卸锁(3);所述口盖组合结构(1)由蜂窝夹芯结构(11)、第一预埋件(12)、第二预埋件(13);布置在机身大型封闭水密舱上界面上,同时也是非增压区通舱地板操作区域,此地板快卸口盖,通过快卸锁(通过一级快卸,不需要借用特殊专用工具),可实现快速进入封闭水密舱维护油箱等各系统;此地板快卸口盖上表面与周边地板一致(无特殊外凸物),可满足应急救援设备操作空间使用。
