Description
Technical field
The utility model relates to unmanned plane field, particularly a kind of unmanned plane preventing crashing.
Background technology
Agricultural development trend must be intensive Quantity production pattern, and using mechanized tool to substitute manual work is in such a mode one of necessary condition, and wherein a kind of approach of spraying insecticide uses unmanned plane to carry agricultural chemicals aloft to spray.In the operation process that existing unmanned plane is sprayed insecticide, because some unforeseen circumstancess may be wounded by exotic, or self produces mechanical breakdown, under this state may there is air crash accident in unmanned plane, and unmanned plane is once crash, economic loss is very large, and oil plant, pesticide solution etc. that unmanned plane carries may contaminated environment.
Summary of the invention
The object that the utility model will reach is to provide a kind of unmanned plane preventing crashing, and can prevent unmanned plane air crash from damaging when having an accident.
In order to achieve the above object, the utility model adopts following technical scheme: a kind of unmanned plane preventing crashing, comprise body, processing unit and engine is provided with in body, processing unit is electrically connected with engine, body is provided with rotor, rotating shaft is provided with in body, rotating shaft is provided with groove near one end of rotor, rotor is provided with connecting portion, connecting portion inserts in rotating shaft groove, connecting portion and rotating shaft interference fit, the rotating shaft other end is connected with engine transmission, cartridge bag and lower cartridge bag is provided with in the groove of rotating shaft, upper cartridge bag is provided with the parachute after collapsible with prescribe medicine parlor, parachute is connected with groove inner wall by line, parachute has the first sharp-pointed detonator of bottom, first detonator is provided with dividing plate with prescribe medicine parlor, upper cartridge bag is other is provided with the second detonator, second detonator is electrically connected with processing unit, also be provided with acceleration induction device in body, acceleration induction device is electrically connected with processing unit.
The acceleration/accel of acceleration induction device Real-Time Monitoring unmanned plane, when unmanned plane receives installation damage, the acceleration be not inconsistent with regular flight condition will inevitably be there is, processing unit obtains this information by acceleration induction device and contrasts with the data of normal flight, show that unmanned plane is in air crash state once analyze, processing unit controls the second detonator and ignites upper cartridge bag, after upper charge detonation, rotor is released in the groove of rotating shaft, thus abandon rotor, parachute after collapsible in groove is pushed downwards simultaneously, the first detonator under parachute is made to puncture dividing plate, ignite lower cartridge bag, parachute is released outside groove after igniting by lower cartridge bag, thus release a parachute, parachute is connected with groove inner wall by line, thus under the unmanned plane of air crash state is suspended on parachute, guarantee safety, because upper cartridge bag and lower cartridge bag are successively ignited in this process, therefore the process descending cartridge bag to release parachute does not affect by upper cartridge bag.In addition, when engine or rotor et out of order, the processing unit be electrically connected with engine can obtaining information, thus also can trigger parachute under the state not detecting disorderly acceleration/accel at acceleration induction device.The trigger mode of upper cartridge bag, lower cartridge bag can avoid parachute to be blocked by rotor.
Further, described first detonator is striker.The cost of striker is lower, and blasting effect is good.
After adopting technique scheme, the utility model tool has the following advantages:
Unmanned plane installs parachute system additional, thus protection unmanned plane prevents from crashing.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the schematic diagram of a kind of embodiment of the utility model;
Fig. 2 is the schematic diagram that the parachute of Fig. 1 embodiment is opened;
Fig. 3 is the schematic diagram of the parachute contraction state of Fig. 1 embodiment.
Detailed description of the invention
Fig. 1-3 is depicted as a kind of embodiment of the present utility model.
A kind of unmanned plane preventing crashing, comprise body 1, processing unit and engine is provided with in body 1, processing unit is electrically connected with engine, body 1 is provided with rotor 2, rotating shaft 3 is provided with in body 1, rotating shaft 3 is provided with groove 4 near one end of rotor 2, rotor 2 is provided with connecting portion 5, connecting portion 5 inserts in rotating shaft 3 groove 4, connecting portion 5 and rotating shaft 3 interference fit, rotating shaft 3 other end is connected with engine transmission, cartridge bag 6 and lower cartridge bag 7 is provided with in the groove 4 of rotating shaft 3, the parachute 8 after collapsible is provided with between upper cartridge bag 6 and lower cartridge bag 7, parachute 8 is connected with groove 4 inwall by line 9, parachute 8 has the first sharp-pointed detonator 10 of bottom, first detonator 10 is striker, the cost of striker is lower, and blasting effect is good, dividing plate 11 is provided with between the first detonator 10 and lower cartridge bag 7, upper cartridge bag 6 is other is provided with the second detonator 12, second detonator 12 is electrically connected with processing unit, also be provided with acceleration induction device in body 1, acceleration induction device is electrically connected with processing unit.
The acceleration/accel of acceleration induction device Real-Time Monitoring unmanned plane, when unmanned plane receives installation damage, the acceleration be not inconsistent with regular flight condition will inevitably be there is, processing unit obtains this information by acceleration induction device and contrasts with the data of normal flight, show that unmanned plane is in air crash state once analyze, processing unit controls the second detonator 12 and ignites upper cartridge bag 6, after upper cartridge bag 6 explodes, rotor 2 is released in the groove 4 of rotating shaft 3, thus abandon rotor 2, parachute 8 after collapsible in groove 4 is pushed downwards simultaneously, the first detonator 10 under parachute 8 is made to puncture dividing plate 11, ignite lower cartridge bag 7, parachute 8 is released outside groove 4 after igniting by lower cartridge bag 7, thus release a parachute 8, parachute 8 is connected with groove 4 inwall by line 9, thus the unmanned plane of air crash state is suspended on parachute 8 times, guarantee safety, because upper cartridge bag 6 and lower cartridge bag 7 are successively ignited in this process, therefore the process descending cartridge bag 7 to release parachute 8 does not affect by upper cartridge bag 6.In addition, when engine or rotor 2 et out of order, the processing unit be electrically connected with engine can obtaining information, thus also can trigger parachute 8 under the state not detecting disorderly acceleration/accel at acceleration induction device.The trigger mode of upper cartridge bag 6, lower cartridge bag 7 can avoid parachute 8 to be blocked by rotor 2.
Except above preferred embodiment, the utility model also has other embodiment, those skilled in the art can make various change and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the scope that the utility model claims define.
