Description
Technical field
This utility model is related to floating air-bag field, more particularly, it relates to a kind of annular special helicopter floating air-bag.
Background technology
At present domestic helicopter floating air-bag is cylindrical or spherical, and by installing mechanism helicopter ventral is assemblied in
Or on slide rail, the program is primarily adapted for use in the less helicopter of take-off weight.For some big payload helicopters, its floating air-bag holds
Product need it is sufficiently large helicopter could be floated on the water surface, floating air-bag take up room it is larger, in order to avoid floating air-bag with
Air weapon etc. is interfered, and needs a kind of annular special floating air-bag, can be assemblied on helicopter wheel axle.Simultaneously to profile
Streamlined design is carried out, when reduction floating air-bag inflates shaping in the air, impact of the air drag to helicopter flight situation.
The content of the invention
The technical problems to be solved in the utility model is, there is provided a kind of annular special helicopter floating air-bag.
This utility model solves the technical scheme that its technical problem adopted：Construct a kind of annular special helicopter floating
Air bag, including air bag main body annular in shape, are provided with Air filling and discharging valves, relief valve, intake valve, the air bag on the air bag main body
The two sides inner side of main body is mounted on connection sheet, and multiple connecting holes are offered in the connection sheet；The air bag main body is radially
Connect band is installed, the two ends of the connect band are equipped with closure ring；Also include installing mechanism, the air bag main body inflation shaping
Afterwards installing mechanism is connected with connection sheet, connect band.
In such scheme, three inner chambers are provided with inside the air bag main body.
In such scheme, each described inner chamber is respectively arranged with Air filling and discharging valves, relief valve, intake valve.
Implement this utility model annular special helicopter floating air-bag, have the advantages that：
The profile of air bag main body is designed as annular special structure in this utility model, by connection sheet, connect band by air bag
Main body is connected with installing mechanism, in assembling and helicopter wheel axle.Floating air-bag inflation shaping back wall is wound on wheel periphery, solves
Problem of the large-scale floating air-bag in ventral position installation difficulty.
Description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing：
Fig. 1 is the structural representation of this utility model annular special helicopter floating air-bag；
Fig. 2 is the scheme of installation of this utility model annular special helicopter floating air-bag.
In figure：Air bag main body 1, connect band 2, connection sheet 3, relief valve 4, Air filling and discharging valves 5, intake valve 6, installing mechanism 7.
Specific embodiment
In order to be more clearly understood to technical characteristic of the present utility model, purpose and effect, accompanying drawing is now compareed detailed
Illustrate specific embodiment of the present utility model.
As shown in Figure 1-2, this utility model annular special helicopter floating air-bag, including air bag main body 1 annular in shape, gas
Capsule main body 1 is shaped by high-strength gastight material, and three inner chambers are provided with inside air bag main body 1, when one of inner chamber is damaged,
Other two inner chambers still can provide enough buoyancy, it is ensured that helicopter floats on the water surface, improve floating air-bag reliability.Air bag
An intake valve 6 of relief valve 4, of Air filling and discharging valves 5, is equipped with main body 1 each inner chamber.Relief valve 4 is used for air bag master
Pressure release under the high-pressure situations of body 1, protects air bag main body 1；Air filling and discharging valves 5 are detected and safeguarded for air bag main body 1；Intake valve 6 is gas
The intake interface of 1 three inner chambers of capsule main body.
The two sides inner side of air bag main body 1 is mounted on connection sheet 3, and multiple connecting holes are offered in connection sheet 3.Preferably,
The front inner side of air bag main body 1 is provided with four connection sheets 3, and reverse side inner side is provided with six connection sheets 3.Air bag main body 1 is along footpath
To connect band 2 is provided with, the two ends of connect band 2 are equipped with closure ring.Preferably, the quantity of connect band is 12.This utility model
Annular special helicopter floating air-bag also includes installing mechanism 7, and the inflation of air bag main body 1 shaping rear connecting piece 3 is by rope and peace
Mounting mechanism 7 connects, and the closure ring at the two ends of connect band 2 is respectively in the upside of installing mechanism 7, downside connection.
When the emergent forced landing of helicopter, the inflation shaping rear connecting piece 3 of air bag main body 1 is connected by rope with installing mechanism 7,
The closure ring at the two ends of connect band 2 is respectively in the upside of installing mechanism 7, downside connection so that floating air-bag is assemblied in helicopter wheel
On axle, the little one end of floating air-bag front face area turns forward at a certain angle during assembling, and one is can to reduce helicopter on the water
During forced landing, impact of the air drag to aircraft flight situation after floating air-bag inflation shaping；Two is can to slow down helicopter in forced landing
Drag effect of the instant water by the water surface, is conducive to helicopter to keep with good aquosity gesture.
In addition, this utility model annular special helicopter floating air-bag is installed on wheel after helicopter, helicopter left and right sides
Assembling one.Floating air-bag profile shrinks one end for position windward and water position, it is possible to reduce air drag after inflation shaping
Adverse effect and water surface resistance to helicopter flight situation the adverse effect of water attitude to helicopter.
Embodiment of the present utility model is described above in conjunction with accompanying drawing, but this utility model is not limited to
The specific embodiment stated, above-mentioned specific embodiment be only it is schematic, rather than restricted, this area it is common
Technical staff under enlightenment of the present utility model, without departing from this utility model objective and scope of the claimed protection situation
Under, many forms can be also made, these are belonged within protection of the present utility model.
