Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underwater vehicle recovering apparatus.

[0002]

2. Description of the Related Art An example of an underwater vehicle equipped with a recovery device conventionally used for seabed exploration and the like will be described with reference to a partially cutaway side view of FIG. A propulsion device 4 is attached to a rear end 3 of a cylindrical body 2 having a streamlined front head 1 so that the vehicle can sail underwater.

In order to levitate and recover the underwater vehicle used for seabed exploration and the like near the sea surface, a small-diameter cylindrical portion 5 is provided at the front of the vehicle body 2 following the forehead 1. Provided, the cylindrical portion 5
A bladder 6 is mounted in a contracted state on the outer periphery of the housing and is housed, and an outer shell 7 which is divided in a circumferential direction and is separable is mounted on the outside thereof.

[0004] A gas generating source 8 is provided inside the tubular portion 5 by a chemical reaction of explosives or the like, and a communication hole 9 is formed in the tubular portion 5.

[0005] When recovering the underwater vehicle after being used for seabed exploration or the like, if gas is generated from the gas generating source 8 by remote control, the gas from the gas generating source 8 passes through the communication hole 9. It flows into the inside of the bladder 6 and inflates the bladder 6.

When the bladder 6 is inflated, the outer shell 7 is separated by being pushed by the bladder 6 and falls off from the body 2 of the vehicle.

Further, the floating bag 6 continues to expand, and as shown in FIG. 4, due to the buoyancy of the floating bag 6, the underwater vehicle has its forehead 1 up and the body 2 of the vehicle is vertical and close to the water surface. Surface.

After the underwater vehicle has surfaced, sound waves are propagated into the water from a sound generator (not shown) provided inside the forehead 1 or the body 2 of the vehicle, and the underwater vehicle floats. Since the position of the underwater vehicle is known, the underwater vehicle can be accommodated using a boat or the like.

[0009]

However, in the conventional underwater vehicle recovering apparatus, a small-diameter cylindrical portion 5 is provided on the vehicle body 2 and the floating bag 6 is housed on the outer periphery thereof. When a large moment acts on the underwater vehicle, such as at the time of firing, it is necessary to increase the thickness of the cylindrical portion 5 so that the vehicle body 2 can withstand this moment. Underwater vehicles tend to increase in weight.

When the underwater vehicle rises as shown in FIG. 4, in a model in which a sound generator (not shown) is provided inside the forehead 1, the forehead 1 is exposed above the water surface and In a model in which the sound wave cannot be propagated to the watercraft and the sound wave generator is provided at a position close to the forehead 1 of the hull body 2, the sound wave is hindered by the inflated bladder 6 and In some cases, it did not propagate along the road.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an underwater vehicle recovery apparatus capable of improving the weight and strength of a vehicle body.

[0012]

In order to achieve the above object, in the underwater vehicle recovery apparatus according to the present invention, a separable frontal hollow body attached to a front end of a body of a vehicle is provided. A gas bladder which is housed in the hollow body and is separated from the frontal hollow body by being supplied with gas to expand outward, a gas cylinder disposed in the body of the sailing body and filled with gas, and the gas cylinder A sealing stopper for closing the gas discharge port of
The gas cylinder is provided with a gas flow path for connecting a gas discharge port of the gas cylinder to a floating bag, and an opening device for opening the sealing plug.

In the underwater vehicle recovery device of the present invention, the bladder is housed in a separable frontal hollow body attached to the front end of the vehicle body, and the vehicle body has a uniform diameter. It is formed into a shape to reduce the weight and improve the strength of the hull body.

[0014]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 and 2 show an embodiment of the underwater vehicle recovery apparatus according to the present invention. A mounting ring 11 is provided on the inner periphery of the front end of a cylindrical vehicle body 10. As shown in FIG. The mounting ring 11 is separated from the front surface of the mounting ring 11 by a partition wall 12.
A streamlined frontal hollow body 13 which is continuous with the front end outer shape is attached.

The frontal hollow body 13 is separable from the mounting ring 11, and a retractable bladder 14 is housed inside the frontal hollow body 13.

The gas inlet 15 of the floating bag 14
Is externally fitted to a cylindrical portion 16 protruding from the center of the bulkhead 12 on the side opposite to the body of the running body, and is fixed by a fastening ring 17.

A mounting block 18 is fixed to a surface of the bulkhead 12 on the side of the hull body 10.
A gas cylinder 19 is attached to the lower side of 8.
An opening device 20 is provided inside the mounting block 18.

The gas cylinder 19 is filled with a high-pressure gas such as carbon dioxide, and the gas discharge port 21 of the gas cylinder 19 is closed with a sealing plug 22 such as a metal foil.

A mounting ring 23 is tightly fitted around the outer periphery of the gas discharge port 21 so that the mounting hole 2 of the mounting block 18 is provided.
4 and the mounting ring 23 is fixed to the mounting block 18 so that the gas cylinder 19 is attached to the mounting block 18.
Attached to.

The opening device 20 comprises a piston 25, a rod-like projection 26 protruding from the piston 25, and a plug 28 filled with a gas generating agent 27.

The piston 25 is fitted on a cylinder 29 provided on the mounting block 18 so as to communicate with the mounting hole 24, and has a rod-like projection 26 protruding from the piston 25.
Gently penetrates a communication hole 30 that connects the cylinder 29 and the mounting hole 24, and faces a position immediately close to the sealing plug 22.

The gas passage 3 is provided on the side of the cylinder 29.
One end of the gas passage 31 is open, the gas flow passage 31 passes through the partition wall 12, and the other end of the gas flow passage 31 is opened at the center of the cylindrical portion 16.

The plug 28 is fitted on the mounting block 18 and is used to heat and react the medicine 27 with the lead wire 3.
2 is attached, and the portion filled with the medicine 27 communicates with the counter communication hole side of the cylinder 29.

When recovering the underwater vehicle, when a current is applied to the lead wire 32 by remote control, the medicine 27 is rapidly burned to generate gas.

The combustion gas enters the cylinder 29 and presses the piston 25, breaks through the sealing plug 22 at the end of the projection 26, and opens the sealing plug.

When the sealing plug 22 is opened, the gas cylinder 1
9 is injected from the gas discharge port 21, enters the cylinder 29 through a gap between the communication hole 30 and the outer periphery of the projection 26, and further flows into the gas passage 31 and the cylindrical portion 1.
After passing through 6, the gas flows from the gas inlet 15 into the bladder 14.

The bladder 14 begins to expand due to the high-pressure gas that has flowed in, and separates and drops off the separable frontal hollow body 13 to expand further outward.

When the bladder 14 is inflated to a certain extent to generate buoyancy, the body 10 of the airframe starts to rise together with the bladder 14.

At this time, if the bladder 14 can be inflated to such an extent that the buoyancy necessary for starting to raise the body 10 of the craft is generated, the body 10 of the craft together with the bladder 14 starts to rise, and the water depth increases. The water pressure around the bladder 14 decreases as the depth decreases, and the bladder 14 further expands. Therefore, when the hull body 10 starts to rise, the bladder 14 should not be inflated more than necessary.

When the amount of high-pressure gas required to inflate the bladder 14 is insufficient with one gas cylinder 19, a plurality of gas cylinders 19 are mounted on the mounting block 18.

As the hull 10 continues to rise together with the buoy 14 due to the buoyancy caused by the expansion of the buoy 14, the buoy 14 rises to the sea surface as shown in FIG. 14 hangs.

As a result, sound waves emitted into the water from a sound wave generator (not shown) provided inside the body 10 of the vehicle are propagated along the water surface without being hindered by the bladder 14, and the underwater vehicle Since the position at which is floating is known, the underwater vehicle can be reliably recovered using a boat or the like.

As described above, in the underwater vehicle recovery apparatus shown in FIGS. 1 and 2, the bladder 14 is housed in the frontal hollow body 13 attached to the front end of the body 10 of the underwater vehicle. Since the body 10 has a uniform diameter, the weight and strength of the hull 10 can be reduced.

The underwater vehicle recovery apparatus of the present invention is not limited to the above-described embodiment, but may be modified without departing from the scope of the present invention.

[0036]

As described above, according to the underwater vehicle recovery apparatus of the present invention, the following various excellent effects can be obtained.

(1) The bladder is housed in a frontal hollow body attached to the front end of the body of the sailing body, and the body of the sailing body is formed to have a uniform diameter. Lightening and improvement in strength can be achieved.

(2) Since the body of the marine vessel floats while being suspended from the inflated bladder, the propagation of sound waves from the sonic oscillator provided in the body of the marine vessel into the water is hindered by the bladder. Instead, the position of the underwater vehicle can be reliably grasped and the underwater vehicle can be easily accommodated.
