Description
Technical field
The present invention relates to unmanned plane field, particularly a kind of unmanned plane preventing from crashing.
Background technology
Agricultural development trend is necessarily intensive large-scale production pattern, is substituted using mechanized tool in such a mode
Manual work is one of essential condition, and the approach that one of which is sprayed insecticide is to carry pesticide using unmanned plane to spray in the air.
In the operation process that existing unmanned plane is sprayed insecticide, because some fortuitous events may be wounded by exotic, or itself
Produce mechanical breakdown, unmanned plane under this state is it may happen that air crash accident, and unmanned plane is once crash, and economic loss is very
Greatly, and the oil plant that carries of unmanned plane, pesticide solution etc. may pollute the environment.
Content of the invention
Present invention purpose to be reached is to provide a kind of unmanned plane preventing and crashing, and can prevent when having an accident no
Man-machine air crash damage.
In order to achieve the above object, the present invention adopts the following technical scheme that：A kind of unmanned plane preventing from crashing, including machine
Body, is provided with processing unit and engine in body, processing unit is electrically connected with engine, and body is provided with rotor, is provided with and turns in body
Axle, rotating shaft is provided with groove near one end of rotor, and rotor is provided with connecting portion, in connecting portion insertion rotating shaft groove, connecting portion with turn
Axle interference fit, the rotating shaft other end is connected with engine transmission, is provided with medicated bag and lower medicated bag in the groove of rotating shaft, upper medicated bag with
It is provided with the parachute after collapsible, parachute is connected with groove inner wall by line, and it is sharp that parachute has bottom between medicated bag
The first trigger, the first trigger is provided with dividing plate with prescribe medicine parlor, is provided with the second trigger by upper medicated bag, the second trigger with
Processing unit electrically connects；It is additionally provided with acceleration induction device, acceleration induction device is electrically connected with processing unit in body.
The acceleration of acceleration induction device real-time monitoring unmanned plane, when unmanned plane receives installation and damages, will necessarily occur
The acceleration not being inconsistent with regular flight condition, processing unit obtains this information the data with normal flight by acceleration induction device
Contrasted, once analysis show that unmanned plane is in air crash state, processing unit controls the second trigger to ignite upper medicated bag, medicine-feeding
After bag blast, rotor is released in the groove of rotating shaft, thus abandoning rotor, simultaneously by the parachute after the compression of groove interior folding
Push downwards, make the first trigger under parachute puncture dividing plate, ignite lower medicated bag, parachute is released recessed by lower medicated bag after igniting
Outside groove, thus releasing a parachute, parachute is connected with groove inner wall by line, thus the unmanned plane of air crash state is suspended on landing
It is ensured that safety under umbrella, because upper medicated bag and lower medicated bag are successively ignited during this, therefore descend the process of medicated bag release parachute not
Affected by upper medicated bag.Additionally, when engine or rotor break down, the processing unit electrically connecting with engine can obtain information,
Thus parachute also can be triggered in the state of acceleration induction device does not detect the acceleration of disorder.Upper medicated bag, lower medicated bag
Triggering pattern can avoid parachute to be blocked by rotor.
Further, described first trigger is striker.The cost of striker is relatively low, and blasting effect is good.
After technique scheme, the invention has the advantages that：
Install parachute system additional on unmanned plane, thus protecting unmanned plane to prevent from crashing.
Brief description
The invention will be further described below in conjunction with the accompanying drawings：
Fig. 1 is the schematic diagram of an embodiment of the present invention；
Fig. 2 is the schematic diagram opened of parachute of Fig. 1 embodiment；
Fig. 3 is the schematic diagram of the parachute contraction state of Fig. 1 embodiment.
Specific embodiment
Fig. 1-3 show a kind of embodiment of the present invention.
A kind of unmanned plane preventing from crashing, includings body 1, is provided with processing unit and engine in body 1, processing unit and
Engine electrically connects, and body 1 is provided with rotor 2, is provided with rotating shaft 3 in body 1, and rotating shaft 3 is provided with groove 4 near one end of rotor 2, rotation
The wing 2 is provided with connecting portion 5, in connecting portion 5 insertion rotating shaft 3 groove 4, connecting portion 5 and rotating shaft 3 interference fit, rotating shaft 3 other end with draw
Hold up and be in transmission connection, be provided with medicated bag 6 and lower medicated bag 7 in the groove 4 of rotating shaft 3, between upper medicated bag 6 and lower medicated bag 7, be provided with collapsible
Parachute 8 afterwards, parachute 8 is connected with groove 4 inwall by line 9, and parachute 8 has the first sharp trigger of bottom
10, the first trigger 10 is striker, and the cost of striker is relatively low, and blasting effect is good, is provided between the first trigger 10 and lower medicated bag 7
Dividing plate 11, is provided with the second trigger 12 by upper medicated bag 6, the second trigger 12 is electrically connected with processing unit；It is additionally provided with body 1 and add
Speed sensor, acceleration induction device is electrically connected with processing unit.
The acceleration of acceleration induction device real-time monitoring unmanned plane, when unmanned plane receives installation and damages, will necessarily occur
The acceleration not being inconsistent with regular flight condition, processing unit obtains this information the data with normal flight by acceleration induction device
Contrasted, once analysis show that unmanned plane is in air crash state, processing unit controls the second trigger 12 to ignite upper medicated bag 6,
After upper medicated bag 6 blast, rotor 2 being released in the groove 4 of rotating shaft 3, thus abandoning rotor 2, groove 4 interior folding being compressed simultaneously
Parachute 8 afterwards is pushed downwards, makes the first trigger 10 under parachute 8 puncture dividing plate 11, ignites lower medicated bag 7, and lower medicated bag 7 draws
After quick-fried, parachute 8 is released outside groove 4, thus releasing a parachute 8, parachute 8 is connected with groove 4 inwall, thus falling by line 9
The unmanned plane of machine state is suspended on parachute 8 times it is ensured that safety, because upper medicated bag 6 and lower medicated bag 7 are successively ignited during this,
The process that parachute 8 released by medicated bag 7 is therefore descended not affected by medicated bag 6.Additionally, when engine or rotor 2 break down, and draw
The processing unit holding up electrical connection can obtain information, thus in the state of acceleration induction device does not detect the acceleration of disorder
Also parachute 8 can be triggered.Upper medicated bag 6, the triggering pattern of lower medicated bag 7 can avoid parachute 8 to be blocked by rotor 2.
In addition to above preferred embodiment, the present invention also has other embodiments, and those skilled in the art can be according to this
Invention is variously modified and deforms, and without departing from the spirit of the present invention, all should belong to claims of the present invention and be determined
The scope of justice.
