The specific embodiment
Referring to Fig. 1 and Fig. 2, a kind of fence apparatus that the utility model embodiment provides comprises: air bag 1, enclosure seat 4, fastener 6 and Air filling and discharging valves group 9; Air filling and discharging valves group 9 is placed in air bag 1 bottom, for controlling the inflation/deflation of air bag; Air bag 1 is annular, by fastener 6, is fixed on enclosure seat 4, and enclosure seat 4 is fixed on submersible hatch 7; When submersible navigates by water on the water surface, be filled with air in air bag 1, it is expanded and at submersible hatch 7 places, form fence, prevent that seawater is splashed into hatch.
Referring to Fig. 3, when submersible is bubbled through the water column navigation, in order to prevent seawater, by submersible hatch 7, be splashed into cabin, by air compressor, to the interior air feed of air bag 1, air bag 1 expands and forms fence; When submersible is wanted dive, the air by the emptying air bag 1 of Air filling and discharging valves group 9, tighten up air bag 1.
Referring to Fig. 4, Air filling and discharging valves group 9 comprises: steam supply valve, charge valve and blow off valve; Steam supply valve is in normally open, and the one end is connected with air compressor, and the other end is connected with the admission port of air bag by charge valve; During to the interior inflation of air bag 1, open charge valve when needs; Blow off valve is connected with the air extractor duct of air bag 1, when needs are packed up fence, opens blow off valve, evacuation of air.For handled easily, the Air filling and discharging valves group can adopt electromagnetic valve by electrical control, thereby promotes the degree of automation of the inflation/deflation operation of air bag 1.
The internal pressure of air bag 1 must remain in safe air pressure range; Therefore, too high in order to prevent air pressure, jeopardize air bag 1; Preferably, in air bag 1 bottom, safety valve is set, the safe air pressure of safety valve is set according to actual conditions; When the air pressure in air bag 1 is too high, self-bleeding, the safety of assurance air bag 1.
In view of pressure-controlled in 1 pair of air bag requires very highly, preferred, steam supply valve, charge valve and blow off valve adopt the relatively high needle-valve of precision, thereby guarantee the precision of inflation and exhaust process, reduce the probability of occurrence of safety misadventure.
Hatch fence behaviour person gangway, while coming in and going out for the reduction personnel, cause the scuffing of air bag 1 to damage; Preferably at air bag 1 top, top cover 2 is set, the cross section of top cover 2 takes the shape of the letter U, and can encase well air bag 1; Top cover 2 is bonding with air bag 1 top, along with the inflation/deflation up-and-down movement of air bag 1.
Tighten up at air bag 1, during the submersible dive, in order to prevent current or buoyancy, make air bag 1 at random simultaneously; Preferably, catch gear is set, for locking top cover 2 when tightening up air bag 1.Catch gear is reed 3, is fixed on enclosure seat 4, and the cross section of reed 3 is V-shaped, and the sidewall of the top cover 2 be complementary is offered v-depression; When locking top cover 2, only need to press down top cover 2, reed 3 gets final product with the v-depression laminating of the sidewall of top cover 2.When to air bag 1 inflation, the stressed reed 3 that gradually breaks away from of top cover 2.
According to the fence needs of submersible reality, the form that can also superpose by air bag expands the fence height, and a plurality of air bag connecting bridges communicate, thereby can once complete the operation of air bag inflation/deflation.
Below by a specific embodiment explanation the utility model.
The fence apparatus that the present embodiment provides is comprised of 9 inflatable annular arrangement air bags 1 that link together, and at air bag 1 top topmost, a light-duty top cover 2 of aluminum is set.The two side of top cover 2 arranges v-depression, can with enclosure seat 4 on the V-shaped reed in cross section 3 coordinate, locking top cover 2, protection air bag when the fence apparatus unaerated.The base of fence apparatus supports with support 5, is fixedly mounted on the hatch at submersible top.
When fence apparatus is deposited, the groove that is blocked top cover 2 by the reed 3 on enclosure seat 4 is fixed.The bolt of clip 3 is also for the time compressing air bag 1 that stops top cover 2 to be subject to drops.The neoprene adhesive plaster that air bag is 1100D with base cloth is made, and between adjacent air bag, is interconnected.The volume of each air bag is 40L.Air bag external diameter after each inflation is 115mm, and air bag arranges 9 altogether, and after inflation, bottom-to-top-height can reach 1035mm.After venting, air bag can be with flat form tiling, and its thickness is slightly larger than the summation of all air bag wall thickness.Generally, after the air bag of wall thickness 2mm venting, deposit the wall thickness that gap is no more than 1.5 times, bottom-to-top-height when all air bags are deposited is in 100mm.There is the air bag extended structure in the air bag outside of bottom, is bolted on enclosure seat 4, and the air bag at top has flange, and the groove fit in flange and top cover 2 is bonding.Top cover 2 is protection air bag 1 when storage configuration fully.
The air sac sealing of bottommost bonding 10 air extractor vents that rigid plastic is made, an air extractor vent is connected with steam line by flexible pipe; Other air extractor vent is connected with safety valve.Air is filled with from air extractor vent to inflatable annulus, fence is extensible.Inflatable annulus adopts high strength (1100D) neoprene adhesive plaster to make.The service life of this material and intensity can meet the demands well.
3 needle-valves are set in Air filling and discharging valves group 9 altogether, according to the difference of installation site, are called air feed needle-valve, inflating needle valve and discharging needle-valve.Generally, the air feed needle-valve is normally open, and inflating needle valve and discharging needle-valve all keep normally off.In the time of need to inflating to fence apparatus, open inflating needle valve and get final product; While finishing using rear venting, close the air feed needle-valve, inflating needle valve and discharging needle-valve are opened simultaneously, just the gas in air bag 1 can be emitted.
Air bag can work under the pressure of 0.03MPa, and it is 0.2MPa that maximum can be born pressure.If work under maximum pressure always, influential to the service life of air bag, therefore recommend the operation pressure of safety valve all is set to 0.03MPa.The quantity of safety valve is 9, and during with full admission capacity input air, safety valve still can guarantee that pressure in inflatable annulus is in normal condition.
The utility model surrounds a fence by inflatable air bag, prevents that seawater is splashed into submersible; Reduce the quality of Fence structure, thereby alleviated the impact of Fence structure on the submersible center of gravity; On the other hand, Fence structure can tighten up in exhaust, thereby can also reduce the impact of Fence structure on the line style fairing of submersible surface when completing waterproof.
It should be noted last that, the above specific embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to example, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
