The emergent slow descending device of body safety is particularly necessary.
Utility model content
The purpose of this utility model is to provide a kind of emergent slow descending device, including garment body, the helmet, air bag, gas
Generating means, height above sea level detection means；The air bag be arranged at garment body outside, respectively centered on left front, chest,
Side is symmetrical arranged before and after side, shank before and after back, arm, thigh, is set along collar ring-type at neck；Positioned at chest, back, leg
The outer surface that the air bag in portion has double-decker, balloon outer sets thread gluing；The gas generating unit includes gas-forming agent
And apparatus to cause bursting, it is separately positioned in each air bag；Apparatus to cause bursting and height above sea level detection means wireless connection.
In a kind of implementation method of the present utility model, the material of balloon outer is PA66LNG carbon fiber enhanced nylons.
In a kind of implementation method of the present utility model, the garment body has carbon fiber protective layer.
In a kind of implementation method of the present utility model, the gas-forming agent includes sodium azide (NaN3) or ammonium nitrate
(NH4NO3)。
In a kind of implementation method of the present utility model, the gas-forming agent is wrapped in air bag lower end, apparatus to cause bursting one
End contacts with gas-forming agent.
In a kind of implementation method of the present utility model, the apparatus to cause bursting include detonator, primacord, Electric spark ignitor,
Conductance detonating primer.
In a kind of implementation method of the present utility model, the height above sea level detection means is arranged on garment body abdomen part
Domain.
In a kind of implementation method of the present utility model, the air bag is connected with garment body with suture way.
Beneficial effect：The utility model can make personnel it is emergent drop to certain height when, form spherical air bag
Human body is wrapped in inside by group structure, forms 360 degree of tight protections.And prevent air bag overall by hard sharp thing when landing
Puncture, ensure the personal safety of landing personnel.
Brief description of the drawings
Fig. 1 is the front schematic view that a kind of parachute of the utility model opens emergent slow descending device when failing；1, the helmet；
2, garment body；3, air bag；4, height above sea level detection means；
Fig. 2 is the schematic rear view that a kind of parachute of the utility model opens emergent slow descending device when failing；1, the helmet；
2, garment body；3, air bag.
Specific embodiment
To cause that the utility model realizes above-mentioned purpose, feature and advantage and can be more obvious understandable, with reference to tool
Body implementation method is described in further detail to the utility model.
Emergent slow descending device schematic diagram during failure, including clothes are opened for a kind of parachute of the utility model such as Fig. 1~2
Body 2, the helmet 1, air bag 3, and height above sea level detection means 4；The garment body includes clothes and trousers, is protected with carbon fiber
Sheath, the air bag 3 be placed in garment body outside, respectively centered on left front, before and after chest, back, arm, thigh side,
Side is symmetrical arranged before and after shank, and ring-type is set at collar, is be arranged in parallel with waist at hip；Positioned at chest, back, leg gas
Capsule has double-decker, and air bag outer layer is made up of PA66LNG carbon fiber enhanced nylons, and the position that outer surface contacts with adjacent cells sets
Put thread gluing；The gas generating unit includes gas-forming agent and apparatus to cause bursting, is separately positioned in each air chamber；The gas
Propellant is wrapped in air bag side, and one end of apparatus to cause bursting is goed deep into gas-forming agent, and the gas-forming agent includes Azide
Sodium (NaN3) or ammonium nitrate (NH4NO3)；The apparatus to cause bursting is connected with height above sea level detection means.
The air bag is connected with garment body with suture way, the carbon fiber protective layer that garment body has, it is ensured that gas
Moment for being inflated to air bag of chemical reaction and air bag in rapid ejection in propellant, the carbon fiber protective layer pair of clothes there is
Body plays cushioning effect, prevents human body to be subject to the impact of air bag to injure.
The height above sea level detection means is arranged on garment body abdomen area, is filled with the ignition in the air bag of front
Put and be directly connected to, with the air bag wireless connection positioned at back, four limbs.The height above sea level detection means can select height above sea level and pass
Sensor, or pressure-altitude sensor BA5803, pressure-altitude sensor BT5611, pressure-altitude sensor HP203B；It is described to draw
Quick-fried device can select detonator, primacord, conductance detonating primer, Electric spark ignitor.
After pilot ejection or aircraft distress passenger's forced landing, the height above sea level detection means in slow descending device of meeting an urgent need
Detect apart from ground distance be less than 50m when, send signal to the apparatus to cause bursting in air bag, apparatus to cause bursting is struck sparks, or pass through
Apparatus to cause bursting transmits electric current or electric spark to gas-forming agent, makes the solid sodium azide (NaN in gas generating unit3) or nitre
Sour ammonium (NH4NO3) rapid reaction of decomposing, produce nitrogen or nitrous oxide (N2O) gas, full of air bag.In the process
In, even if when the apparatus to cause bursting with altitude sensor wireless connection cannot receive signal, the gas positioned at front occurs
Agent produces the impulsive force of moment because of violent chemical reaction to the air bag of surrounding, in the air bag at four limbs, back, hip
Gas-forming agent is subject to the percussion for closing on air bag generation to chemically react rapidly in succession, is airbag aeration, plays double guarantors
The effect of danger is ensuring airbag-releasing.Because pressure is acted on after airbag-releasing, mutually extruded between each air bag, adjacent air bag passes through
The thread gluing of outer surface is interconnected, and spherical air bag group structure is integrally formed human body is wrapped in into inside, forms tight 360
Degree protection.Air bag outer layer is made up of PA66LNG carbon fiber enhanced nylons, is resistant to high pressure, make it is overall in spherical air bag
Do not punctured by hard sharp thing during land, and as inertia is effectively upspring, to slow down the impact of moment of falling.
Protection domain of the present utility model is not limited merely to above-described embodiment, every spirit in the utility model design
Within principle, any modification, equivalent and improvement that one of skill in the art can make etc. should be included in this reality
Within new protection domain.
