The invention discloses an emergency floating device for a helicopter. The emergency floating device comprises a buoy assembly, an inflation assembly and a control system used for achieving manual starting and automatic starting after entering water. The control system comprises water immersion sensors with four corners distributed on the front side and the rear side of the machine body, a manual starting switch used for inputting manual starting signals and a control box used for controlling the inflation assembly according to the signals of the water immersion sensors and the manual starting switch. The control box comprises three control panels; the single control panel judges that the current state is a water entry state when receiving the water entry signals of the at least two water entry sensors, and the control box determines that the water entry signals are received when the at least two control panels judge that the current state is the water entry state; entering a water entering automatic starting mode when the manual starting signal is not input and the water entering signal is determined to be received; and when a manual starting signal is input and the at least two control panels receive the manual starting signal, a manual starting mode is started. The device can be manually started and automatically started after entering water, and has high control reliability.
本发明公开一种直升机应急漂浮装置,包括浮筒组件、充气组件、用于实现手动启动和入水自动启动的控制系统;控制系统包括四角分布在机体前后两侧的浸水传感器、用于输入手动启动信号的手动启动开关、用于根据浸水传感器和手动启动开关的信号控制充气组件的控制盒;控制盒包含三个控制板;单个控制板在收到至少两个浸水传感器的浸水信号时则判断当前为入水状态,至少两个控制板判断当前为入水状态时则控制盒确定收到入水信号;未输入手动启动信号且确定收到入水信号时即进入入水自动启动模式;输入手动启动信号且至少两个控制板收到手动启动信号时即进入手动启动模式。该装置能实现手动启动和入水自动启动,具有较高的控制可靠性。
