Have at boats and ships topple danger or the initial stage in capsizing case generation, by automatically discharging the air bag of topside, having helped adjustment method of ship floating condition, reaching to slow down and topple, even stop the generation of toppling.Preresearch estimates, if install a length 10 meters, the air bag that diameter is 6 meters, has been enough to the buoyancy providing 226 tons when launching completely.In case of emergency, this has been enough to produce actively impact to method of ship floating condition, slows down disaster and occurs, for salvage work tries to gain time precious to one.
Further, described air bag 3 is spherical in shape.
Further, described air bag 3 outer wrap one deck netting structure.Netting can available protecting airbag apparatus, is conducive to air bag and is firmly fixed on hull, is convenient to persons falling in water simultaneously and captures, persons falling in water can be helped to save oneself.
Further, the operator's compartment of described boats and ships is provided with tele-control system, and described tele-control system is for artificially initiatively triggering described boats and ships Overthrow preventing device takes preventive measures against overturning.
Further, air bag dispose procedure adopts the mode without electricity operation that is pneumatic or hydraulic pressure.
Further, air bag is made up of flexible canvas or rubber or other equivalent materials.
Further, air bag storing compartment 2 mounting means embeds hull or hangs on topside.
The beneficial effects of the utility model are:
1) implement conveniently, with low cost, and the good results are evident.
2) when danger is imminent, or when boats and ships are out of control, the security implementation depending on boats and ships itself all can lose efficacy, but the technical solution of the utility model is still effective, do not rely on any Systematical control and human users, can automatically complete a series of actions such as perception, inflation, release.
3) netting of air bag outside is offered help for personnel save oneself, and gains time also to extraneous rescue.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Existing technology, mainly at the design-build initial stage, by changing hull design, or installs the object that the equipment such as antirolling apparatus reach increase hull stability.Be all consider to reduce in normal state the possibility of toppling and occurring, under the state that accident occurs later or boats and ships are out of control, the positive role that can play is very little.But due to ship's navigation on the water, the uncertainty of external environment is very large, because the reasons such as inclement weather, misoperation or shock cause accident, once accident inevitably there occurs, the utility model just plays a role at crucial moment, passive triggering release, slows down disaster and occurs, for salvage work gains time.
See Fig. 1-Fig. 2, the utility model needs the position hull is suitable to install some air bags for subsequent use.Mounting means as shown in Figure 1.Setting height(from bottom) should higher than hull center-of-gravity position, and high as far as possible, so just can provide larger restoring force.Sharp objects or corner angle can not be had around installation site, prevent air bag from after deployment breakage occurring.
Can vary in size according to boats and ships, type difference adjustment air bag quantity and size.Air bag is made up of flexible canvas or elastomeric material, can complete harvesting and launch action, and having certain toughness, to prevent from being scratched by hull structure.
See Fig. 3-Fig. 4, normal condition lower gasbag is collected in air bag storing compartment 2, is flexibly connected, and enough firmly bear the buoyancy of air bag by some anchor fittings 6 with hull structure.Air bag cabinet is provided with the air bag cabinet door 5 that can remove, and it is provided with submurged pressure induction installation 4.Collecting state air bag cabinet door 5 can have certain close property, to protect airbag apparatus.After accident occurs, boats and ships run-off the straight, when water logging is less than balloon positions, submurged pressure induction installation 4 just can sense hydraulic pressure, and triggers automatic releasing device, air bag cabinet door 5 first Automatic-falling, and gas filled device gives airbag aeration rapidly simultaneously.Under air-inflated pressure, air bag can launch rapidly outward at hull, provides extra buoyancy to hull, makes up hull and to intake the not enough problem of the stability that causes.
Air bag 3 outer wrapping one deck netting structure 7, can available protecting airbag apparatus, is conducive to air bag simultaneously and is firmly fixed on hull.Meanwhile, after air bag 3 launches, as a large-scale floating debris, netting structure 7 is convenient to persons falling in water and is captured, and can provide relief to persons falling in water.
Owing to having installed several airbag apparatus outside hull, hull has started the position of soaking at first, and air bag will launch at first, and progressively slows down hull.These airbag apparatus, except having automatic release function, are also provided with tele-control system at operator's compartment.If navigating mate has found the trend of ship capsize in advance, also can artificial release air bag device, make counter-measure as early as possible.Air bag dispose procedure adopts the mode without electricity operation, to guarantee having an accident, still can play a role when dead electricity.
In order to ensure when danger is imminent, air bag automatically can discharge and protect hull can not to topple very soon sinking.The utility model is outside hull, and the place higher than center-of-gravity position arranges the air bag that can automatically discharge, and this is one of key of the present utility model.
Comparatively speaking, technology of the present utility model is easy to implement, with low cost, and the good results are evident.When danger is imminent, or when boats and ships are out of control, the security implementation depending on boats and ships itself all can lose efficacy, but technology of the present utility model is still effective, do not rely on any Systematical control and human users, can automatically complete a series of actions such as perception, inflation, release.There is provided side group for personnel save oneself, gain time also to extraneous rescue.
