Abstract

PROBLEM TO BE SOLVED: To provide a method wherein, when a mine is laid, the method is adapted to flexibly deal with all situations from submarines, war vessels, and aeroplanes, and the same is adapted to freely deal with any mode of a sunk bottom system and an anchor-hold system after it is laid in the sea. SOLUTION: A mine couples separably a head structure composed of a buoyancy structure and a head can structure including an explosive compound and an ignitor, and a tail part composed of an anchor-hold part and a tail can including an explosive compound. When both of the head and the tail are laid in the sea, the head and the tail are sunk on the sea bottom and laid as a bottom sunk mine in the state where the head and the tail are kept combined, while the head is laid as a can structure mine of an anchor-hold type mine in the state where the head structure and the tail are separated. Herein, the tail structure is used as a bottom sunk bottom mine serving also as an anchor- hold of an anchor-hold type mine, and further when an anchor-hold rope coupling the head and the tail is cut owing to sea cleaning, buoyancy of the head is made invalid and is sunk on the sea bottom and laid as a bottom sunk mine.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for laying a mine, which can flexibly be applied to either a sinking type or a mooring type according to the conditions of the sea area when the mine is laid in the sea.

[0002]

2. Description of the Related Art In general, mines are indispensable for harbors, local defenses, destruction of maritime traffic routes and the like, and are classified into moored mines and sinking mines according to their laying conditions.
Moored mines are laid with the firing mechanism moored underwater. That is, the weight is on the sea floor, and a can body having an ignition mechanism is fixed to the weight by a wire or the like. A sinking mine is one that sits on the sea floor and explodes in response to the hull's magnetism, water pressure, and radiation.
Both were used properly depending on the situation. The conventional mooring mine had a function of only attacking the target in the can body having the explosive, and the mooring device as a weight had only a role of simply mooring the can body. The weak point of this mooring mine was that if the rope mooring the can body from the weight was cut off by minesweeping, the can body would float, and the only option was to self-destruct or self-sink.

[0003]

However, in recent years, potential threats have changed, and the era in which mines are to be laid in the target sea area has come to an era in which it is not possible to accurately predict the operation scene to be dealt with. Therefore, the present invention is to solve the weaknesses of the conventional mine, and to provide a mine laying method that can flexibly respond to any operational situation,
It is intended to provide a method of laying mines that can be laid from submarines, ships, and aircraft, and that can be freely adapted to both sinking type and mooring type after laying in the sea. .

[0004]

The present invention has solved the above problems by employing the following means. That is, a head composed of a buoyant body part and a head can body part provided with explosives and a firing device, and a tail part composed of a stay device part and a tail can body part provided with explosives and a firing device The body and the body are detachably connected. When both the head body and the tail body are laid in the sea from a ship or a submarine, the head body and the tail body are landed on the sea floor while the head body and the tail body are connected to each other to form a sinking mine. Also, with the head body and the tail body separated, the head body is made a canned body mine of a mooring mine, while the tail body is
This is a sinking mine that also serves as the mooring section of the mooring mine. Further, at this time, if the mooring line connecting the head body and the tail body is cut off by sweeping, the buoyancy of the head body disappears, and the head body bottoms on the sea floor. Let it operate as a sinking mine. In the buoyant body part, fill and inflate the gas into a flexible folded airtight and pressure-resistant bag, thereby generating buoyancy on the head body,
The buoyancy was extinguished by discharging this gas. In addition, the buoyancy may be generated by a pressure-resistant container having a cavity, and the buoyancy may be eliminated by injecting seawater into the cavity. Further, the tail body is provided with a descent device such as a parachute, and is dropped from an aircraft while the head body and the tail body are connected, and when the head body and the tail body land on the sea surface, the descent device is mounted on the tail body. Disconnect from Thereafter, it is laid as a sinking or mooring mine in the same manner as when it was laid from a ship or submarine.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of a mine for carrying out the method of the present invention will be specifically described with reference to the drawings. In FIG. 1, a head body 10 and a tail body 20 are connected to a coupling / separation device 30.
Are connected so as to be separable. The head body 10 includes an inflatable buoyant body part 11 and a head can body part 1 including an ignition device 14 having an explosive 13 and an arming device 15.
2 is comprised. On the other hand, the tail body 20 is composed of a tail can body part 22 having an anchoring device part 21 and an explosive 24 and an ignition device 23 having an arming device 25.

[0006] The head body 10 has a head 1 so that the air resistance is reduced when dropped from an aircraft, and the water resistance is reduced when laid from a submarine.
0a is formed in a hemispherical shape, and a body 10b following the head 10a is formed in a cylindrical shape. An inflatable buoyant body 11 is incorporated in a hemispherical cover of the head 10a of the head body 10. That is, the inflatable buoyant body 11
Fills and inflates a flexible, folded, air-tight and pressure-resistant bag, thereby allowing the head 10
The buoyancy is formed to generate buoyancy, and the buoyancy is extinguished by discharging gas.

[0007] A pressure relief valve (not shown) is provided in the bag.
By providing the head, even if the depth (external pressure) of the head can body portion becomes small, the difference between the internal pressure / external pressure applied to the back can be kept constant, and the strength of the bag can be so large. It can be something that is not required.

In place of the inflatable buoyant body 11, buoyancy is generated by a pressure-resistant container having a cavity, and a mechanism for injecting seawater into the cavity is provided. Seawater may be injected to eliminate buoyancy.

A firing device 14 having an explosive 13 and an arming device 15 is built in a cylindrical body portion 10b of the head body 10. The ignition device 14 includes an electric circuit unit, a sensor, a battery, and the like (all not shown). The arming device 15 is composed of a safety release mechanism that mechanically matches the firing sequence of the explosive by an external force (water pressure or the like) due to the environment. When the arming device 15 and the firing device 14 detect a target, It explodes an explosive. A depth sensor (not shown) built into the firing device 14 indicates that the head body 10 has been minesweeped or that the mine of the tail body 20 has fired and the function as a weight has been lost. At this time, it is detected that the depth of the head body 10 changes and the head body 10 floats.

The tail body 20 has a built-in cylindrical mooring device 21 having a mooring line feeding mechanism, a tail can body 22 containing explosives, and a firing device 23 having an arming device. Have been. That is, the maintenance device unit 21
The head body 10 is maintained at a predetermined depth, and is housed in a space 20 a provided at one end of the tail body part 20.
One end of the mooring line is connected to the convex portion 10c at the rear end of the head body 10, and the other end is connected to the mooring line unwinding mechanism 21a. An ignition device 23 having an arming device 25 is arranged adjacent to the space 20a of the tail body 20, and an explosive 24 is loaded around the ignition device 23 to form a tail can body portion 22. ing.

The coupling / separation device 30 is composed of, for example, a band having a U-shaped bracket and a release device composed of a device utilizing the explosive force of explosive. That is, at each end of the head body 10 and the tail body 20, there is provided a groove to which a metal fitting of the band is attached. By being wound, both the head body 10 and the tail body 20 are joined.

The descent device 40 is used when a mine is dropped from an aircraft and laid in the sea, and a parachute is attached to a rear part of the tail body 20 of the mine.

When the head body 10 and the tail body 20 are connected to each other and laid in the sea and reach a certain depth, the head body 10 and the tail body 20 are kept connected to each other, and the sinking type is set. A means (depth sensor or the like) for determining whether to use a mine or separate a mooring mine is used as the head body 10 or the tail body 2.
Place it in preparation for one or both of the zeros.

An example of a mine for carrying out the method of the present invention is constructed as described above. Next, the operating state of the mine will be described. First, when the mine is laid as a sinking mine, FIG. As shown in 3, from a ship or submarine,
When you release a mine into the sea, it sinks under its own weight,
Both the head body 10 and the tail body 20 lie on the sea floor and wait. At this time, the arming device 15 is actuated by receiving an external force such as water pressure or the like, the safety of the safety device is released, and the device is turned on. The firing device 14 is activated by power supply, and outputs a firing signal to the arming device when detecting the approach of a target. In response to this signal, the arming device 15 explodes the explosive 13 and harms the target.

Next, when the mine is laid as a mooring type mine, as shown in FIG. 2, when the mine is released into the sea from a ship or a submarine, the mine sinks by its own weight. When the mine is deeper than a predetermined depth and has landed on the seabed, the coupling / separation device 30 shown in FIG. 1 is operated to release the coupling between the head body 10 and the tail body 20 to separate them. At this time, since the inflatable buoyant body 11 is built in the head body 10, the head body 10 floats in the sea due to the buoyancy. At this time, the head body 10 and the tail body 20 are connected by the mooring line. The length is the difference between the predetermined depth and the sea floor. . Then, when the approach of the target is detected, an ignition signal is output to the arming device 15, and in response to this signal, the arming device 15 explodes the explosive to harm the target.

At this time, since the explosive 24 and the ignition device 23 are also built in the tail body 20, the tail body 20 also operates as a sinking mine. That is, when the sensor disposed on the tail body 20 detects the approach of the target, the sensor issues an ignition signal to the arming device 25, and in response to this signal, the arming device 25
Explodes 4 and harms the target.

By the way, when the head body 10 is floated in the sea and moored from the tail body 20 via the mooring line and is laid as a so-called mooring type mine, and the mooring line is cut by minesweeping. The head body 10 tends to rise to the sea surface due to its buoyancy. At this time, when the gas of the inflatable buoyant body constituting the buoyancy of the head body 10 is released, the buoyancy disappears (if the buoyancy is generated by a pressure-resistant container having a hollow portion, the water injection mechanism is provided. When the buoyancy disappears by operating and putting seawater into the hollow portion), the buoyancy disappears, and the head body 10 sinks and sinks to the seabed by its own weight. The head body 10 then operates as a sinking mine. That is, since the head body 10 has a built-in arming device and a firing device, when the approach of a target is detected, the firing device 14 and the arming device 15 are activated to explode the explosive and the target device. Harm things.

When a mine is laid from an aircraft, the tail body 2
The head body 10 and the tail body 20 are slowly dropped in the air by the descent device 40 such as a parachute attached to one end of the zero, and when the water reaches the sea surface, the fall device 40 is separated from the tail body 20. The head body 10 and the tail body 20 sink toward the sea floor. Hereinafter, in the same manner as the case of laying from the above-mentioned ship or submarine, it can be freely laid in either a sinking type or a mooring type according to the environment of the target sea area.

[0019]

According to the present invention, as described above, the head body and the tail body are detachably connected to each other, and the tail body is also provided with an arming device.
With a built-in ignition device and explosives and a function to eliminate buoyancy in the head, compared to the conventional method, the sinking type and the mooring type are compatible with the environment of the target sea area. If both can be freely selected and laid as a mooring type, even if the mooring line is cut by minesweeping, the buoyancy of the head will disappear, and the head will land on the seabed and will sink again. Since it is operated as a bottom type mine, it has the effect of stopping the opponent from being confused when the sinking type mine appears in the sea area where it should have been swept.
