Description
Technical field
The present invention relates to the escape devices in aviation security field more particularly to a kind of aircraft flight.
Background technology
With being showing improvement or progress day by day for science and technology, the trip of people also becomes more and more convenient.As efficiently long-distance travel tool,
Aircraft receives the very big welcome of passenger, but due to the danger and uncertainty of high-altitude flight so that the hedging energy of aircraft
Power and the ability of emergency escape are all greatly limited.How aircraft distress escapes and is one and must face and that thinks deeply asks
Topic, on the one hand, then need the passenger and crew to escape that can promptly make a response, preferably adequately prepare；On the other hand,
It is constrained again by survival equipment, how to be escaped not when most of passenger in aircraft flight for encountering problems
Solution, for how to be even more to have half knowledge by survival equipment escape, this brings no small difficulty to escape；A Man Escaped into
Also by environmental constraints whether work(, once aircraft breaks down or airplane crash occurs, people are difficult the hope for having escape, and final machine is ruined
People dies, and massive losses are brought to people's life and property.
Invention content
The present invention is in order to solve the problems, such as escape of the aircraft in flight course, it is proposed that a kind of aircraft escape device.
The present invention is achieved through the following technical solutions：A kind of aircraft escape device is escaped including the first escape scuttle, second
Raw window, third escape scuttle, escaping chair, escape compartment.
The escaping chair includes：Backrest, parachute, parachute ejection plate, pull rod, parachute ejection spring, unlocking lever, lock
Spring, rubber pad, rocking arm, the first lock pin, the second lock pin, lock, screw rod, locking bar, storeroom.
Wherein, the locking bar is fixed on backrest top, and rocking arm is arranged on the left end of locking bar, and unlocking lever, which is mounted on, to be fixed on
On screw rod below seat, it can be rotated around screw rod.Pull rod upper end is connected with rocking arm by the first lock pin, and snap and the first lock pin connect
It connects, rubber pad is fixed on the opposite side of backrest, buffering during for human body stress；The lower end of pull rod and the upper end of unlocking lever by
Second lock pin connects；Backrest overcomes the pressure of parachute ejection spring that parachute ejection plate and parachute are pressed into backrest together,
It is connected by parachute and lock.Storeroom is arranged on the lower part of escaping chair, be equipped in the storeroom oxygen tank, drug, food with
And water etc. is used for the article of first aid.
The escaping chair is by escaping chair fixed mount setting in the cabin of escape compartment；The cabin includes upper cabin under
Cabin；The escape compartment be separately positioned on the first escape scuttle, the second escape scuttle, third escape scuttle corresponding section machine
Inside cabin.
Several ejectors are equipped between the escape compartment and airplane skin, which is made of piston and piston cylinder, should
Piston is set on inside piston cylinder, which is equipped with the cage connection of piston rod, the piston rod and escape compartment, and piston is being moved through
Escape compartment is driven to be detached from aircraft by piston rod in journey, be additionally provided with the sliding slot coordinated with piston rod on piston cylinder, set in the sliding slot
There is sealing strip, which connect with the winding wheel in piston, and during piston motion, sealing strip is pulled out from winding wheel,
Moment ensures the sealing of piston cylinder, and the rear end of piston cylinder is equipped with fuel chambers, is equipped with fuel in the fuel chambers, is produced by fuel combustion
Raw pressure propelling piston movement, and then escape compartment is popped up into aircraft from escape scuttle.
Escape compartment is hit by a bullet after getting off the plane from escape scuttle, and the parachute in escaping chair is opened, and gradually drops escape compartment
Ground is dropped down onto, so as to ensure the life security of escape personnel.When escape compartment lands, the buffer unit positioned at escape compartment bottom is beaten
It opens, prevents the impact force between escape compartment and ground from again resulting in injury to escape personnel.
The present invention advantageous effects be：The present invention is provided with escape scuttle and escape compartment in the different bay sections of aircraft,
Once airplane crash occurs, the passenger inside escape compartment can quickly and efficiently be ejected aircraft, simultaneously as escape compartment, escape
The multiple-protection of chair, parachute and buffer unit can ensure the successful possibility of passenger's escape, because of escape to the maximum extent
Final goal be escape planning can, if escape passenger during escape because by losing lift energy when injuring again
Enough, then all survival equipments will become without in all senses.
