Abstract
The invention relates to an active inflating type buffer device for an airdrop object. The active inflating type buffer device for the airdrop object comprises an airdrop parachute pack connected with the airdrop object and a buffer air bag and further comprises a starting pull rope and an inflating fan, wherein one end of the starting pull rope is wound around a rotary shaft of an impeller of the inflating fan, the other end of the starting pull rope is connected with the airdrop parachute pack, an air outlet of the inflating fan is connected with the buffer air bag through an air duct, the airdrop parachute pack pulls the starting pull rope after airdrop, the impeller of the inflating fan is driven by the starting pull rope to rotate, and the buffer air bag is inflated by the inflating fan through the air duct. The active inflating type buffer device for the airdrop object has the advantages that operation is easy and convenient, the inflation speed is high, a gas cylinder, a motor and other driving devices are not needed, the weight of an airdrop system is reduced, and the requirement for landing buffer of large-tonnage equipment can be met.
Description
Technical field
A kind of the present invention relates to dropping gear, more particularly, it relates to active inflatable cushioning device of air-drop object.
Background technology
Existing no cargo airdrop system mainly using the inflatable cushioning system that certainly falls, beat when landing by aerial delivery parachute
Open, play the effect of deceleration, buffer air bag needed to inflate before air-drop object lands, to play the effect of buffering.Existing
From falling, inflatable cushioning system is provided with the aeration blower fans such as gas cylinder, motor, its complex structure poor reliability, the inflation of buffer air bag
Speed is slow, buffer air bag may be led to cannot to complete gas replenishment process before landing, therefore it is suitable only for current 10 tonnes
Equipment material air-drop is it is impossible to meet the buffer requirement of more big load aerial delivery system.
Content of the invention
The technical problem to be solved in the present invention is, provides that a kind of structure is simple, the active of dependable performance air-drop object
Inflatable cushioning device.
The technical solution adopted for the present invention to solve the technical problems is: a kind of active inflated type of construction air-drop object delays
Flushing device, eases up qi of chong channel ascending adversely capsule including with the air-drop air-drop pack that is connected of object, also includes startup drawstring and aeration blower fan, described opens
In the rotating shaft of impeller in described aeration blower fan for one end coiling of dynamic drawstring, the other end is connected with described air-drop pack, described fills
The gas outlet of gas blower fan is connected with described buffer air bag by air channel；Air-drop pack pulls startup drawstring after air-drop, and startup is drawn
Rope drives the wheel rotation of aeration blower fan, and aeration blower fan is inflated to buffer air bag by air channel.
In such scheme, in described air channel, it is provided with check valve, when buffer air bag internal pressure reaches predetermined value, check valve
Two-way closing.
In such scheme, described buffer air bag is provided with two, is connected with described aeration blower fan by two air channels respectively.
In such scheme, described buffer air bag is provided with tearing port.
Implement the active inflatable cushioning device of the air-drop object of the present invention, have the advantages that
During air-drop, air-drop pack can pull startup drawstring during stretching, and start drawstring and drive the impeller of aeration blower fan to turn
Dynamic, the process that aeration blower fan is inflated to buffer air bag by air channel.The present invention is easy and simple to handle, and aeration speed is fast, is not required to
The driving means such as gas cylinder, motor, mitigate aerial delivery system weight and disclosure satisfy that large-tonnage equips the demand of landing buffer.
Brief description
Below in conjunction with drawings and Examples, the invention will be further described, in accompanying drawing:
Fig. 1 is the side view of the active inflatable cushioning device of air-drop object；
Fig. 2 is to start drawstring and drop the schematic diagram that pack is arranged on air-drop object；
Fig. 3 is to start the front view that drawstring is connected with aeration blower fan；
Fig. 4 is to start the side view that drawstring is connected with aeration blower fan；
Fig. 5 is the schematic diagram that aeration blower fan is connected with air channel.
Specific embodiment
In order to be more clearly understood to the technical characteristic of the present invention, purpose and effect, now comparison accompanying drawing describes in detail
The specific embodiment of the present invention.
As Figure 1-Figure 5, the active inflatable cushioning device in the air-drop object of the present invention includes dropping pack 3, delays
Qi of chong channel ascending adversely capsule 6, startup drawstring 2 and aeration blower fan 5.
Air-drop object 1 is connected with air-drop pack 3 and buffer air bag 6, and air-drop pack 3 can be opened in air-drop and play deceleration
Effect, inflation during buffer air bag 6 landing, play the effect of buffering when air-drop object 1 lands.Start one end coiling of drawstring 2
In the rotating shaft of the impeller of aeration blower fan 5, the other end is connected with air-drop pack 3.The gas outlet of aeration blower fan 5 pass through air channel 4 with
Buffer air bag 6 connects.During air-drop, air-drop pack 3 can pull startup drawstring 2 during stretching, and coiling is in the rotating shaft of impeller
Start drawstring 2 can constantly be drawn out, thus driving the wheel rotation of aeration blower fan 5, aeration blower fan 5 passes through air channel 4 to buffering
Air bag 6 is inflated.The controlled system of aeration blower fan 5 blower outlet blast controls, and it drops the weight equipped certainly according to single-piece
The dynamic blast adjusting aerator gas outlet, to reach the purpose of inflation.
Buffer air bag 6 is provided with two, is connected with aeration blower fan 5 by two air channels 4 respectively.Respectively equipped with one in air channel 4
Individual check valve, the closure of check valve is controlled by buffer air bag 6 internal pressure, and after internal pressure reaches predetermined value, check valve is automatic
Two-way closing, buffer air bag 6 is in packing stage.
Buffer air bag 6 is provided with tearing port, and buffer air bag 6 is in closed state after starting inflation, tearing port automatic bonding,
When air-drop equipment lands, buffer air bag 6 is squeezed, and tearing port opens, buffer air bag 6 aerofluxuss, reaches the purpose of buffering.
Above in conjunction with accompanying drawing, embodiments of the invention are described, but the invention is not limited in above-mentioned concrete
Embodiment, above-mentioned specific embodiment is only schematically, rather than restricted, those of ordinary skill in the art
Under the enlightenment of the present invention, in the case of without departing from present inventive concept and scope of the claimed protection, also can make a lot
Form, these belong within the protection of the present invention.
