The pneumatic harpoon grid of the present embodiment helps the operation principle of fall system to be:
Warship program: warship according to helicopter and help function and the effect of fall system, in warship face navigation system
System guides lower helicopter close to warship face grid, and warship face flies to control room according to sea situation, helicopter, naval vessel
Virtual condition provides warship instruction；When after distance warship face specified altitude assignment warship program start, controller
13 power on, and enter self-check program；Self-inspection waits after completing that flying to control room provides warship signal；Fly control
Room judges whether to meet warship condition according to practical situation, provides signal, go straight up in the case of being unsatisfactory for
Machine goes around, resume waiting for warship instruction, meet under condition give controller 13 warship signal,
Controller 13 is extended by programme-control cylinder piston 2, makes unlocking mechanism 6 quick insertion
Grid 7, wherein unlocking mechanism 6 plays guide effect in certain deflection angle, to ensure lock
Determine cancel system 6 and insert grid 7 smoothly, play latch-release effect；And installing plate 17, buffering
Rubber sleeve 18 can make harpoon grid help fall system normally to work in certain deflection angle；Pass through tension and compression
Force transducer 16 and position switch 5 detect whether to insert, and when being not inserted into, controller 13 controls
Cylinder piston rod 3 is regained, and upper magnetic switch 15 and magnetic switch 14 judge its retracted state,
Resume waiting for warship signal；After insertion being detected, controller 13 controls electromagnetic valve 12 and commutates,
Piston rod is regained, and makes helicopter be fixed on warship face, when pull pressure sensor 16 reaches to specify pressure
After power, being signaled to controller 13, controller 13 controls electromagnetic valve 12 and commutates to middle position,
And the state that sends controls room to flying, close closed system, complete whole warship flow process.
From warship program: warship according to helicopter and help function and the effect of fall system, when helicopter needs
When warship, warship face flies to control room and is given instructs from warship according to sea situation, helicopter, the virtual condition on naval vessel；
Controller 13 powers on, and enters self-check program, and self-inspection waits after completing that flying to control room provides from warship signal.
Fly to control room to judge whether to meet from warship condition according to practical situation, in the case of being unsatisfactory for, provide signal,
Helicopter resumes waiting for from warship signal.Meet under condition give controller 13 from warship signal, gas
Cylinder piston rod 3 extends, and magnetic switch 14 judges whether piston rod 3 stretches out and puts in place, and position
Whether switch 5 detection pressing rotary switch 4 makes unlocking mechanism 6 unlock；When locking solves
After unlocking except mechanism 6, controller 13 controls electromagnetic valve 12 and commutates, and piston rod 3 is quickly received
Returning, upper magnetic switch 15 judges whether piston rod 3 is regained and puts in place, and piston rod 3 reclaims after putting in place,
Controller 13 controls electromagnetic valve 12 and returns to middle position, and sends status information to flying to control room, closes closed system
System, completes whole from warship flow process.
The present invention mainly uses pneumatic actuation mode, makes grid cooperate with harpoon, reaches to go straight up to
The purpose of warship by machine, it is ensured that warship process and the safety of helicopter after warship, and guide helicopter to exist
Warship region correct warship, it is ensured that the safe landing of helicopter and mooring under certain sea conditions,
Have simple in construction, lightweight, maintaining convenience, fast, pollution-free, the low power consumption of speed etc. are excellent
Point, solves the various problems brought in background technology because of hydraulic-driven.
The above, be only presently preferred embodiments of the present invention, not do the structure of the present invention
