Specific embodiment
The technical solution of the utility model is described in further detail with reference to the accompanying drawing:
Embodiment one, a kind of volume expansion type emergency device applied to submariner device, as shown in Figure 1, including closing
Production gas chamber 1, produce gas chamber 1 it is cylindrical, up and down close, produce gas chamber 1 in be filled with gas-forming agent, gas-forming agent select tool
There is the solid material for the features such as factor of created gase is high, density is big and gaseous product is nontoxic non-corrosive；1 side wall of gas chamber is produced circumferentially to be provided with
Several stomatas 1, the bottom centre for producing gas chamber 1 are provided with ignition 12, and ignition 12 includes igniter and control
Device produces 1 bottom of gas chamber and is provided with the combustion-supporting chamber 121 for igniter to be arranged and the control room 122 for controller to be arranged.Produce gas
Hub-type reinforcing rib 13 is provided in room 1.
It produces and is provided with closed filter chamber 2 outside gas chamber 1, filter chamber 2 also for tubular and coaxial arrangement and produces 1 outside of gas chamber.
Stomata 1 is connected to filter chamber 2, and stomata 2 21 is offered in filter chamber 2, and sieve 22, sieve one are provided in filter chamber 2
It is a to be filled in the indoor porous hollow cylinder of filtering.Sieve 22 is connect with 1 outer wall of gas chamber is produced, so that filter chamber 2 is separated,
And stomata 1 is located at 22 lower section of sieve, and stomata 2 21 is located at the top of sieve 22；Air bag 3, stomata are arranged with outside filter chamber 2
2 21 in air bag 3.Filter chamber's side wall is provided with annular groove 23, and the bladder port of the air bag 3 is embedded in annular groove 23 and passes through card
Hoop 231 is fixedly clamped, the three layers of nested structure of use of air bag 3, and inside and outside two layers of use is corrosion-resistant, flexibility is high and heatproof weaving material
Material, the present embodiment select aramid fiber 12 31, and middle layer uses heat resistant rubber 32.
Production gas chamber and combustion chamber in the present embodiment use two-piece unit formula structure, and are screwed on by screw thread 5.
Specific implementation explanation:
There are two types of controlling soil moists for ignition: 1) controller, which receives signal and controls igniter, triggers quick-fried inflation of rising；2)
Using pressure sensor by the pressure signal measured in real time be passed to control room, according to pressure change calculate submariner device fall deep position and
Fall deep rate, then starts emergency device.Computing Principle is as follows:
The relationship of pressure and depth is P=ρ gz under known water, therefore obtains the relationship of vertical velocity and pressure:
Z=z (t) is the position of submariner device during falling depth, now with displacement of volume V1Submariner device for, it is lonely in meet with
When vertical wave, density is by ρ1Sport ρ2(ρ2> ρ1), the suffered resultant force of submariner device sports
F=V1(ρ2--ρ1)g (2)
Formula air bag lifesaving appliance starting of rising quick-fried at this time.Assuming that volume change is approximately constant temperature process after airbag-releasing,
Submariner device falls the deep real-time rising buoyancy that can be provided in the process
P0For standard atmospheric pressure, V2Volume when for airbag-releasing.Then ensure buoyancy before submariner device falls to design maximum depth
Restoring the condition that should meet is
H*≤hc (4)
Referring to Fig. 3, h0、H*And hcRespectively submariner device is reduced to zero and design maximum depth in starting lifesaving appliance, subsidence velocity
The depth of water position of degree.
The emergency device is usually mounted to the position of centre of gravity of submariner device, can be according to the submariner device of different weight on it
Side is installed by multiple emergency devices.To guarantee the equilibrium state of submariner device in water, heart symmetric position should be thought highly of along submariner
Distribution.Specific number can be provided according to minimum bladder volume is calculated.Computing Principle is as follows:
Required gas-forming agent most corpusculum can be calculated according to equation of gas state PV=nRT and quality and molal quantity relationship
Product, with this adjusting apparatus number.
In formula, ρ is seawater averag density, T1For temperature under mark condition, T2For temperature in inflation rear gasbag.If gas in air bag
Average molar mass is Mg, gas-forming agent factor of created gase is η, density ρg。
Working principle is as follows:
Gas-forming agent is enclosed gas to produce in gas chamber, the filtering chamber outer wall of air bag and gas generator is tightly connected, and is adopted
It is actively lighted a fire with pressure signal both of which triggering ignition with remote control, it is fast using rising suddenly and sharply for gas-forming agent chemical reaction
Speed is that air bag is inflated, and provides the rising buoyancy of submariner device with this.
