The invention discloses an anti-backflow drainage structure for a turnover cabin of an airplane, which comprises the turnover cabin externally hung on the airplane, a drainage hole is arranged at the lowest position of a cabin body of the turnover cabin, the anti-backflow drainage structure is arranged at the drainage hole and covers the drainage hole, and a water retaining part and a drainage part are arranged on the anti-backflow structure; the drainage part is communicated with the drainage hole, and the water retaining part is located below the drainage hole after the cabin body is turned over. According to the invention, the anti-backflow structure is added to provide a drainage function for the drainage holes in the turnover cabin of the airplane when the cabin body is in different position states, and meanwhile, the anti-raining effect can also be achieved; the drainage hole is simple in structure, convenient to machine and form, low in production cost and capable of being matched with the overturning action of an airplane overturning cabin, the normal drainage function of the drainage hole is guaranteed when the drainage hole is located at the low position, and the good rainwater backflow prevention effect can be achieved when the drainage hole is located at the high position.

    本发明公开了用于飞机翻转机舱的防倒灌排水结构,包括外挂设置在飞机上的翻转机舱,翻转机舱的舱体最低位置设有排水孔,还包括设置在排水孔处并将排水孔覆盖的防倒灌结构,防倒灌结构上设有挡水部和排水部;排水部与排水孔连通,挡水部位于舱体翻转后的排水孔下方。本发明能够通过增加防倒灌结构来为飞机翻转机舱上的排水孔提供舱体处于不同位置状态时的排水功能,同时还可起到防淋雨的效果;本发明的结构简单、便于加工成型、生产成本低廉,能够与飞机翻转机舱的翻转动作相适配,在排水孔处于低位时保证排水孔的正常排水功能,在排水孔处于高位时又能赋予其良好的防雨水倒灌效果。
