The invention relates to a safety lock device for preventing a ram air turbine from being mistakenly released, and belongs to the technical field of aviation emergency energy. The safety lock is mainly composed of a safety lock pin assembly, a sleeve assembly, a microswitch, a ribbon and the like. Wherein the two ends of the sleeve assembly are fixed in an aircraft structure, the safety lock pin assembly is connected with a red ribbon printed with a mark of'removing before taking off 'through a rope, and the safety lock pin assembly can be inserted and locked in the sleeve assembly. A lock pin hole is designed on the RAT, and a microswitch is designed on the RAT. After the safety lock pin assembly is inserted into the sleeve assembly, a lock pin head of the safety lock pin assembly is inserted into a lock pin hole in the RAT, the RAT position is locked, and meanwhile a lock pin triggers the microswitch. Signals of the microswitch are transmitted to an aircraft management computer, so that a pilot is informed of the state of the safety lock pin. Before the airplane takes off, a push rod at the head of the installation lock pin assembly is pressed down, the installation lock pin assembly can be pulled out of the sleeve assembly, and meanwhile an alarm signal is relieved.
本发明涉及一种防冲压空气涡轮误释放安全锁装置,属于航空应急能源技术领域。主要由安全锁销组件、套管组件、微动开关、飘带等组成。其中套管组件两端固定在飞机结构中,安全锁销组件与印有“起飞前移除”标识的红色飘带通过绳索连接,安全锁销组件可插入并锁定在套管组件内。RAT上设计有一个锁销孔,并设计一个微动开关。当安全锁销组件插入套管组件后,安全锁销组件的锁销头将插入RAT上的锁销孔中,将RAT位置锁定,同时锁销触发微动开关。微动开关信号传递给飞机管理计算机,从而告知飞行员安全锁销状态。飞机起飞前,按下安装锁销组件头部的推杆,可将安装锁销组件从套管组件中拔出,同时解除告警信号。
