Abstract
The utility model discloses a folding rapid floating security device comprising a frame, and the folding rapid floating security device is characterized in that a folding air sac is equipped in the frame. A protective door is installed at the upper frame of the frame, and an air-driven telescopic rod is equipped between the protective door and the frame. The folding rapid floating security device has the advantages of simple structure, low cost, rapid reaction speed and simple operation. The folding rapid floating security device can be used under water, and the security of boats is improved to prevent the boats and submarines sinking when dangers are met.
Description
Technical field
The utility model relates to the collapsible floating upward quickly protector of a kind of submarine or boats and ships use.
Background technology
At sea or the boats and ships that travel in the rivers generally all have life jacket, buoy quoit, liferaft and life boat.When boats and ships are in danger,, just can only rely on life jacket, buoy quoit, liferaft and life boat to be abandoned ship if it is unsuccessful to speedily carry out rescue work.Can only be equipped with life jacket, buoy quoit for submarine since underwater environment badly to reach hydraulic pressure excessive, even have life jacket, buoy quoit, the possibility of escape also is very little when submarine is in danger, and it is impossible especially to save whole submarine.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, provide a kind of simple in structure, cost is low, speed of response is fast, easy and simple to handle, can improve the ships and light boats safety, prevent the collapsible floating upward quickly protector of sinking when boats and ships or submarine are in danger.
The utility model is achieved in that it has a frame, and its special character is to be provided with collapsible air bag in frame, at the frame upper ledge protective door is installed, and pneumatic expansion link is set between protective door and frame.
Collapsible floating upward quickly protector according to above-mentioned also is connected to the air pressure balance automatic controlling valve on the said air bag, in case when using under water air bag because of the excessive explosion of pressure reduction.
The utility model has the advantages that simple in structure, cost is low, speed of response is fast, easy and simple to handle, the safety that can improve ships and light boats greatly, occupant's safety is guaranteed in sinking when preventing that boats and ships or submarine are in danger.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the utility model working state schematic representation.
Among the figure: 1-frame, 2-protective door, 3-expansion link, 4-air bag, 5-air pressure balance automatic controlling valve, 6-admission port.
The specific embodiment
As shown in the figure, the utility model has a frame 1, is provided with collapsible air bag 4 in frame 1, is connected to air pressure balance automatic controlling valve 5 on air bag 4, upper ledge at frame 1 is equipped with protective door 2, is provided with pneumatic expansion link 3 between protective door 2 inside faces and frame 1 outside face.
When reality connected, this collapsible floating upward quickly protector can be installed in ship, ship two sides of a ship, and the admission port 6 of air bag 4 communicates with floating upward quickly gas tank in being arranged on ships and light boats by tracheae and air valve, and pneumatic expansion link 3 is connected with the pneumatic control system of ships and light boats.(when this collapsible floating upward quickly protector is used for boats and ships, need not to use air pressure balance automatic controlling valve 5.)
When submarine is in danger can't float the time, make pneumatic expansion link 3 actions by pneumatic system, making protective door 2 serves as that axle is opened with the door-hinge that is arranged on upper side frame, the protective door and the ship side of a ship are 90 °, expose folded airbag 4, in folded airbag 4, charge into high pressure air fast by the floating upward quickly gas tank, to the capsule internal gas pressure greater than stopping inflation outside the capsule during hydraulic pressure 15KPa, the buoyancy of air bag 4 drives the submarine floating upward quickly until emerging and reaching safe altitude, guarantee the safety of occupant and whole submarine, whole process generally is no more than 3 minutes.In the submarine floating-upward process, submarine position hydraulic pressure reduces gradually, and folded airbag 4 is exitted in water by air pressure balance automatic controlling valve 5, automatic compensation capsule internal gas pressure, at any time keep intracapsular pressure only greater than about the outer hydraulic pressure 15KPa of air bag, guarantee that air bag 4 can explosion.
When boats and ships are in danger, can be according to boats and ships centre-of gravity shift situation, select collapsible floating upward quickly protector position or whole collapsible floating upward quickly protector at a side of a ship or two sides of a ship or front portion or rear portion to open, the buoyancy that air bag 4 produces prevented that hull from continuing to tilt or sunk because of inclination, thereby avoids the sinking of this ship.
