CN2349130Y - Sinking-resistant or salvaging device for ship - Google Patents

Abstract

The utility model is composed of an air chamber, an air bag, electro-explosive valves and a C-shaped high-pressure container which is filled with non-combustion liquefied gas, which are used as a unit. Each electric-explosive valve is installed on the top part of each spatial position in the ship and under the water line, and each electro-explosive valve is controlled by a switch. When a ship body is in a sea damage emergency situation, the switch switches current, each electro-explosive valve opens simultaneously, the high-pressure gas in the high-pressure container rush at the air chamber, the air bag falls out and expands, the inboard influent water is extruded outside the ship body by the air bag, and the ship body regains buoyancy. When the utility model is used for salvaging a sunken ship, multitude units are arranged in every nook and corner in the sunken ship, the current is switched on above water surface, each electro-explosive valve opens, the air bags of the multitude units are inflated and drain simultaneously, and the sunken ship is quickly floated off in a large area supporting flotation mode by the utility model.

Description

A kind of device that is used for ship Counter-Flooding or salvaging

The utility model relates to a kind of boats and ships and in emergency circumstances prevents the safety device that sinks in average.Also can be used for salvaging a sunken ship fast in the rivers shallow sea.

Many perils of the sea shipwreck accidents are all arranged since ancient times every year, shipbuilding circles has been taked some anti-heavy measures: as separating the boats and ships space with watertight bulkhead, to reach the into heavy hull inclination simultaneously in several cabins of water but water inlet part buoyancy disappears also, through can't stand that new stormy waves hits, on handling, navigation brings very big difficulty, very easily sinking.

I had once obtained patent: " the promptly anti-heavy airbag apparatus of a kind of boats and ships " (ZL-942233484) solved this problem in the theory design, but more complicated because of its making on the actual fabrication, used electromagnetic valve can't reach designing requirement thereby can not fine practicality promote.

The purpose of this utility patent provides and a kind ofly simple in structurely not only can be used for ship Counter-Flooding but also can be used for the device that the rivers neritic province domain is salvaged a sunken ship efficiently.It is by air chamber, air bag and foreskin, and disposable electric blasting valve and fill one unit in the C shaped steel tube composition system of non-ignitibility liquid gas, air chamber wherein, air bag and foreskin are individually fixed in about the flat board.There is opening at dull and stereotyped center, and both are communicated, and electric blasting valve is connected between air chamber and the steel cylinder.

Below in conjunction with accompanying drawing embodiment is described in detail:

The schematic appearance of the one unit of figure one, component devices.

Figure two, unit internal work scheme drawing.

Figure three, after removing dull and stereotyped upper member, see diagrammatic sketch.

Figure four, electric blasting valve structural representation.

A kind of apparatus system that is used for ship Counter-Flooding or salvaging, it is made up of plurality of cells.

Shown in figure one: a special type C font fills non-ignitibility liquid gas steel cylinder 4 and is holding around an air chamber 2.Steel cylinder 4 exhaust heads 26 have exhaust spiral 11.On exhaust head 2 and air chamber 3 siphunculus electric blasting valve 10 is arranged.Air chamber 3 and steel cylinder 4 all are fixed on flat pulling on 5.Dull and stereotyped and following the suspension is fixed with air bag 7, and perimetric pattern is fixed two pages of foreskins 9,6.7 in air chamber 3 and air bag have vent 14.Become rugosity to place two pages of foreskins 9 during air bag 7 unaerateds, in 6, foreskin 9, it is with plasticity male and female hasp 8 that 6 bottoms engage, go up on air chamber 3 tops also has exhaust spiral 2, electric blasting valve 10 is the metal constructions 25 that all can ventilate of across up and down, last pipeline claims that again " explosion chamber " 21 is thinner, following pipeline claims that again " empty chamber " 18 is more roomy, there is metal conical plug 17 to squeeze into from following pipeline 18, tightly block and connect the passage 20 of air chamber and steel cylinder and the path of pipeline 16 respectively, 18 one-tenth empty chambers of blind nut 19 closed conducts, heating wire 22 penetrates formed 22 explosion chambers 21 of putting into low bursting charge in the pipeline 21 through last plug screw 24.The exhaust spiral 11 of steel pipe 4 heads 26 is opened earlier before the unit uses like this, and gas is only blocked by metal conical plug 17 through the passage that pipeline 16 to 20 will enter air chamber 3 again.In use, total electric valve 12 energized 13, the explosive charges that heating wire 22 heating sets off an explosion in the chamber 21 are pushed into down metal closures 17 in the pipeline sky chamber 18.Left and right sides pipeline 16,20 get through, air-flow enters air chamber 3, then make two pages of foreskins 9 with high pressure through dull and stereotyped central authorities mouthful 14 punching press air bags 7,6 hasp 8 unclamps, and air bag 7 presses that quantitative gas expand in the steel cylinder 4, and air bag 7 capacity must be more surpasses gasometry, adapt to body form in the cabin with unsaturated inflated condition, but its draining buoyancy is consistent with quantitative gas.Numerous like this unit is extruded going into inundation in each cabin, keeps the floating of hull.

When anti-heavy, boats and ships are not placed in each unit each cabin of underwater and push up setting sail before, between the skeleton of top, passageway and not the side of occupation of land; With the diving method each unit is fixed in the shipwreck behind the place, every corner, every place with controlling holder power mode floating hull with face with master on off on the water surface with stay hook 1 (or magnet) when salvaging.

Work finishes, and the exhaust spiral 2 of outwarding winding is discharged gas in the air bag 7, folding parcel air bag, and steel cylinder is inflated again, changes electric blasting valve, and the unit is reusable again.
