Description
Technical field
The present invention relates to UAV navigation technical field, especially a kind of UAV navigation of electromagnetic coupling is answered
Anxious safety device.
Background technique
With the fast development of marine economy and the rise of ocean development upsurge, UAV navigation is because it is in the army and the people's neck
The great researching value in domain, becomes the research hotspot of lot of domestic and foreign mechanism.UAV navigation is by carrying different work
The measurement sensor of task carries out undersea detection operation etc., in marine environmental monitoring, Marine Sciences investigation, underwater search and rescue, seabed
Prospecting etc. plays very important effect.
When UAV navigation navigates by water operation under water, the influence and test of complex job environment are on the one hand faced, such as
The mutation of density caused by epilimnion, water plant winding etc. on the other hand there is control system failure, electric quantity of power supply to exhaust etc. itself
Security reliability problem breaks down when to guarantee that UAV navigation navigates by water under water or in emergency circumstances can guarantee necessity
Safety, carry out emergency security system design, it is very necessary to configure corresponding emergency disposal prediction scheme.
Currently, submarine navigation device security system of commonly meeting an urgent need generally comprises two kinds of forms in the prior art, one is
Ballast is installed on submarine navigation device, is cut the rigid connection of ballast and submarine navigation device by fluid power system, by ballast
Jettisoning makes submarine navigation device form positive buoyancy floating, and one is by way of blasting bolt, signal triggers after-explosion bolt certainly
Ballast jettisoning is floated in dynamic explosion.But both have certain use defect, the former hydraulic system dimensional weight is bigger, lead
This Emergency Device mode is caused generally to be only used in the Large Underwaters aircraft such as manned underwater vehicle；When the latter's blasting bolt uses
Itself there is some potential safety problems, while blasting bolt needs to be placed in sealed compartment with water segregation, structure is complicated, and installation makes
With not flexible.
Summary of the invention
The applicant provides a kind of UAV navigation of electromagnetic coupling for the disadvantage in above-mentioned existing production technology
Emergency safety device, consequently facilitating installed and used on the submarine navigation device of different dimensional weights, the device can also directly with
Aqueous medium contact, is installed convenient for general arrangement, using safe flexible.
The technical solution adopted in the present invention is as follows:
A kind of UAV navigation emergency safety device of electromagnetic coupling, including fixed-wing, the structure of the fixed-wing
Are as follows: including electromagnet mounting base, the top of the electromagnet mounting base is provided with spring mounting hole, and the top surface positioned at fixed-wing is provided with
Guide groove, fixed-wing top center side are provided with unilateral slope, and the front end of the fixed-wing is provided with card slot；The fixed-wing
One end installation by adhering have an electromagnet and compressed spring, and will throw and carry the wing and be mounted on fixed-wing, throwings carries the wing and compress
Spring, electromagnet are face contact.
Its further technical solution is:
The bottom of the fixed-wing is fixedly installed with pedestal by fastener, and the side of the pedestal is installed by fastener
There is permeable cabin, further include conducting wire, one end of the conducting wire passes through permeable cabin and pedestal is connect with electromagnet, and the other end passes through watertight
Crossing cabin part is connected with the electric control part inside pressure-resistant cabin.
The electromagnet is closed type, has magnetic attraction under off-position, overcomes the elastic force of compressed spring that will throw and carries the wing
It is firmly sucked, electromagnet loses magnetic force when energization, and compressed spring, which will be thrown, to be carried the wing and flick.
The fixed-wing is manufactured using cast iron materials.
Beneficial effects of the present invention are as follows:
Structure of the invention is compact, reasonable, easy to operate, passes through mechanical part and electric control part cooperating, mechanical part
Outside the external watertight pressure-resistant cabin of aircraft under water, including electromagnet, spring, the throwing load wing, fixed-wing etc., submarine navigation device is normal
Electromagnet is in off-position when work, and adsorption capacity is larger at this time, overcomes spring force or gravity and throwing to carry the wing and passes through face contact
Securely, after having emergency parachute triggering, powering on triggering route powers on electromagnet, and magnetic force weakens, in spring force or again for absorption
Electromagnet is separated with load wing pressure is thrown under the action of power, is thrown the load wing and is cooperated with fixed-wing by slideway structure, is set on slideway
Unilateral slope perturbations are set, the load wing is thrown under spring force or gravity and is moved along slideway, in unilateral slope perturbations
Under the action of with fixed-wing be detached from.Electric control part is built in inside submarine navigation device watertight pressure-resistant cabin, is emergency safety device
Fault identification and triggering system, carry out fault identification to submarine navigation device, lead to when judging that submarine navigation device is in emergency
Cross power on triggering route electromagnet is powered on, make electromagnet magnetic force weaken triggering abandon load the wing.
Meanwhile the present invention is also equipped with following advantage:
One, the present invention is using load wing one is thrown, and small in size, light-weight, resistance is small, easy to install and use；
The present invention is that the throwing of submarine navigation device is carried the wing as load module is thrown, and will throw when emergency floats and carry wing jettisoning, in this way
Extra load need not just be increased as throwing and carry module, while being done work using the adsorption capacity of electromagnet and spring force, both may be used
It directly contacts, is encapsulated without pressure resistance, while the installation shell of electromagnet is not limited by pressure-resistant depth, can be made with water environment
The advantages that it is small in size to ensure that the present invention has for streamlined structure, light-weight, and resistance is small, it is underwater especially suitable for nobody
It is installed and used in aircraft.
By the way of electromagnetic coupling, overcomes spring suction or gravity that will throw by electromagnet suction when normal work and carry part
Be sucked, electromagnet powers on when emergency, and magnetic force weakens, throw carry part under spring action or under self gravitation effect with underwater boat
The separation of row device.
Two, the present invention can make submarine navigation device in emergency circumstances meet an urgent need floating, and realization is saved oneself；
Transfinite when depth occurs in submarine navigation device, control system failure, sharply sink etc. various fault modes when, the present invention
Emergency disposal is carried out, promptly abandons and carries the wing, floats automatically by the buoyancy for carrying and generating is thrown, purpose of saving oneself can be reached.
Three, low in energy consumption, high reliablity of the invention；
The present invention usually in a dormant state, maintains work by low current, once receiving fault message, then judges event
The priority level for hindering information decides whether promptly to throw to be downloaded to rescue by preset trigger mechanism, and power consumption is relatively low, can long-time work
Make.Self-contained independent system of the present invention, circuit structure is simple, using modularized encapsulation, high reliablity.
