Description
Technical field
The present invention relates to air vehicle technique field, specially a kind of unmanned plane protective device of fuel tank.
Background technology
Unmanned plane is that the unpiloted flight manipulated using radio robot and the presetting apparatus provided for oneself is set
Standby, unmanned plane has many advantages, such as small, low cost, easy to use.Currently, unmanned plane take photo by plane, agricultural plant protection, the necks such as mapping
Domain has a wide range of applications.The unmanned plane that aerial survey uses belongs to special defects unmanned plane, this UAV system weight is larger, endurance compared with
Long, groundwork place is mountain area or high altitude localities.Therefore steady to the flight efficiency of unmanned plane, flight safety and whole flight
It is qualitative to have higher requirement.Currently, unmanned plane dynamical system on the market is broadly divided into three classes：First, all-electric unmanned plane；Two
It is fuel power unmanned plane；Third, hybrid power unmanned plane.Fuel power unmanned plane has flight compared to all-electric unmanned plane
The advantages that time is long, loading capacity is big, therefore aerial survey unmanned plane generally uses fuel power unmanned plane.But fuel power unmanned plane
After falling accident occurs, the fuel leakage of fuel power unmanned plane easily causes fire, and there are security risks.
Invention content
The invention is intended to provide a kind of unmanned plane protective device of fuel tank, when power unmanned plane will fall, can reduce
Unmanned plane falling speed mitigates the damage of unmanned plane, and also ensures that fuel tank will not be caused to damage and be leaked, and avoids causing fire
Calamity improves the safety of unmanned plane.
The present invention provides base case：A kind of unmanned plane protective device of fuel tank, including outer container and vibrating sensor, outer container
It is hinged with case lid, airbag and air charging system are equipped in outer container, airbag inner wall is equipped with parachute, air charging system and vibrating sensor electricity
Connection；The airbag is internally provided with fuel tank air bag, and fuel tank air bag is connect with parachute, and fuel tank inside air bag installs fuel tank；It is described
Fuel tank is connected to external oil line pipe, and the oil line pipe is internally provided with cross bar, and the cross bar is located at oil line pipe and stretches into gas
In the caliber of bag, the both sides of cross bar are equipped with telescopic shackle member, and being connected between shackle member and cross bar can closing oil path pipe
The flexible oil sealing in road, oil line pipe inner wall are equipped with the card slot that can block shackle member.
The operation principle of base case：By the present invention on unmanned plane, when unmanned plane is out of control to be vibrated, vibration passes
Sensor will sense that vibration signal sends the controller inside vibrating sensor to, and controller controls air charging system and starts, inflation
Device works, and air charging system just gives air bag inflator, and on the whole airbag expansion becomes after the case lid of case, airbag can fly out outer
Case drives the outer container that flies out together of the fuel tank in airbag to be detached from unmanned plane, fuel tank connect with unmanned plane by oil line pipe, fuel tank
Just it suspends in the air.
While air bag inflator, gas give oil line pipe apply pressure, since pipeline is internally provided with cross bar, then not in contact with
The inner wall of the pipe of cross bar is inwardly got into, i.e., shackle member is pressed into the card slot of oil line pipe.When air bag inflator to explosion after, airbag
The parachute of inner wall is opened, to which parachute slows down the speed that fuel tank and unmanned plane fall, meanwhile, oil line pipe because no longer by
Restore deformation to gas extrusion, at this time since shackle member has been stuck in card slot, oil line pipe restores just to stretch clamping when deformation
Part, shackle member drive flexible oil sealing to extend to and are bonded with oil line pipe inner wall, to enclose oil line pipe, prevent fuel oil from letting out
Leakage.After unmanned plane landing, fuel tank is slowly landed followed by parachute, just will not cause the damage of fuel tank.
The advantageous effect of base case is：1, air charging system fills helium to airbag, is come to ensure that airbag can fly up, from
And fuel tank is driven to be detached from unmanned plane, fuel leakage is avoided on unmanned plane, causes fire, and security risk has been discharged.
2, parachute is set in airbag inner wall, to slow down the speed of falling of unmanned plane and fuel tank, mitigates unmanned plane and fuel tank
Damage.Fuel tank is placed in fuel tank air bag, the born impact force of fuel tank is slowed down, further reaches the effect for mitigating fuel tank damage
Fruit.
3, when gas applies pressure to oil line pipe, shackle member is used for closing oil path pipeline, when unmanned plane falls, no longer
Fuel oil is provided to unmanned plane, after preventing unmanned plane landing from crashing, fuel leakage causes fire.
Preferred embodiment one：As the preferred of basic scheme, the shackle member includes multiple hollow cubes being mutually arranged,
Outermost hollow cube is fixedly connected on cross bar, and the hollow cube of innermost layer is fixedly connected with clamp, clamp both ends
Equipped with hook.
Advantageous effect：When oil line pipe is by gas extrusion, the clamp of shackle member is pressed into the card slot of oil line pipe, card slot
During clamp is pressed into, hook applies pressure to pocket edges, therefore card slot becomes larger, then just pressed completely in clamp and hook
After in into card slot, card slot restores deformation and compresses clamp, and hook is hooked in card slot inner wall.It is simple in structure using this shackle member, it is only sharp
Shackle member can be realized with the inflation of air charging system to be stuck in card slot, need not additionally increase energy.
Preferred embodiment two：Preferably one it is preferred, the hook be equipped with rubber layer.
Advantageous effect：Since hook can catch on the inner wall of card slot, when oil circuit card slot compresses hook, avoids hook from scraping and be broken
Oil line pipe, and it is equipped with rubber layer, increase the frictional force of hook and card slot inner wall, so that hook hooks more securely
On card slot inner wall.
Preferred embodiment three：As the preferred of basic scheme or preferred embodiment two, it is full of inert gas in the fuel tank air bag.
Advantageous effect：Since the atom of inert gas is not easy to lose or obtain electronics, also it is difficult to send out with other materials
Biochemical reaction, so also avoiding fuel tank leakage causes fire.
Preferred embodiment four：Preferably three it is preferred, sealant is equipped in the card slot.
Advantageous effect：Sealant is set so that clamp is stuck in very close to each other in card slot, it is therefore prevented that fuel oil continues from gap
Unmanned plane is flowed by oil line pipe, avoids unmanned plane landing from crashing and causes fire.
