The invention provides a water throwing cabin door of a fire extinguishing aircraft, and belongs to the field of aircraft design. The device is of a two-leaf opposite-opening cabin door structure, key hinges are arranged on the two sides of the two-leaf opposite-opening cabin door structure and hinged to a machine body structure, sealing structures are arranged on the edges of cabin doors, and two opening mechanisms are symmetrically arranged above the cabin doors on the two sides and comprise transmission shafts hinged to the machine body structure, cranks and connecting rods are connected between the cabin doors and the transmission shafts, and the ends of the two transmission shafts are hinged to the same actuator. Opening and closing of the cabin doors are achieved through stretching and retracting of the actuator, the two latch mechanisms are symmetrically arranged above the cabin doors on the two sides and comprise lock shafts hinged to the fuselage structure, lock hooks are arranged in the middles of the lock shafts and matched with lock columns fixed to the cabin doors to lock the cabin doors at the closed position, and the other actuator is matched with the two lock shafts to lock the cabin doors at the closed position. Locking and unlocking of the latch mechanism are controlled through the telescopic movement. A single actuator is adopted to drive the double doors to be opened, and the mechanism synchronism is high; and through the design of the transmission angle of the opening mechanism, small bearing is achieved, and the safety of the mechanism is improved.
本发明提供了一种灭火飞机投水舱门,属于飞机设计领域。本发明为两扇对开舱门结构,两侧设琴键铰链与机身结构铰接,舱门边缘设密封结构,两组打开机构对称布置在两侧舱门上方,包括与机身结构铰接的传动轴,曲柄与连杆连接在舱门与传动轴之间,两个传动轴端部铰接在同一作动器上,通过作动器的伸缩实现舱门的开合,两组闩机构对称布置在两侧舱门上方,包括与机身结构铰接的锁轴,锁轴中部设锁钩,与固定在舱门上的锁柱配合将舱门锁紧在关闭位置,另一作动器与两个锁轴配合,通过伸缩运动控制闩机构的锁定与解锁。本发明采用单作动器驱动双开门打开,机构同步性高;通过打开机构的传动角度设计,实现较小承载,提高了机构的安全性。
