DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, a ship navigation obstruction device 1 includes a housing 2, a battery 3, a gas generation source 4, a strip 5, and a self-sinking device 6. It is a navigational obstruction device.

The housing 2 includes the battery 3 and the gas generating source 4.
And a housing 5, a housing body 7, and a breech member 8.
And

As shown in FIG. 1, the housing body 7 has an outer cylinder 9 which is a cylindrical body having a bottom and an inner cylinder which shares the center axis of the outer cylinder 9 inside the outer cylinder 9. And a tube 10.
The outer cylinder 9 has an opening at one end (a lower end in FIG. 1, which is also referred to as a tip or a warhead).
The inner cylinder 10 is housed inside so as to have a central axis shared with the outer cylinder 9, and the other end (the upper end in FIG. 1 is also referred to as a rear end or a breech). For example, by attaching an annular closing plate 11 to the inner plate 10 and inserting the inner tube 10 into the circular opening of the closing plate 11, the rear end portions of the outer tube 9 and the inner tube 10 are closed. A cylindrical body 12 having an end portion formed into a slightly tapered shape, and a disk-shaped warhead metal member 13 attached to a distal opening of the cylindrical body 12 so as to close the distal opening. And a cylindrical warhead cap 14 having a bottom and attached to the distal end of the cylindrical body 12 so as to share the warhead metal member 13.

The cylindrical body 12, the closing plate 11, the warhead metal member 13, and the inner cylinder 10 form a closed space, and the closed space is made hollow, so that the closed space becomes a floating chamber 15. In the space formed by the cylindrical body 12, the closing plate 11, the warhead metal member 13, and the inner cylinder 10, a ring-shaped plate supported by the inner peripheral surface of the cylindrical body 12 and the outer peripheral surface of the inner cylinder 10 is provided. Are arranged in the central axis direction at predetermined intervals. This reinforcing member 16 allows the cylindrical body 12
The strength of is maintained. The plurality of annular plate-shaped reinforcing members 16 are provided with openings so that adjacent spaces communicate with each other. Due to the opening, the closed space does not become a plurality of divided closed spaces, but becomes one closed space that communicates.

In the present invention, the floating chamber 15
Is formed so as to have a function of floating the ship navigation obstruction device 1 on the sea, so that it is preferable that the room structure is an empty space formed by the outer cylinder 9 and the inner cylinder 10 as described above. However, other configurations may be employed. As another configuration, for example, a specific gravity of less than 1 in a room structure formed by the outer cylinder 9 and the inner cylinder 10 and a soluble filler dissolved by seawater, a decomposable substance decomposed by seawater, or seawater And various kinds of fillers formed of extinguisher substances that disappear due to the above. The floating chamber 15 having the filling preferably has a seawater inlet (not shown) through which seawater can easily enter the room structure from the outside.

The self-sinking device 6 has a communication hole 17 provided in the housing 2, particularly the outer cylinder 9, so that the floating chamber 15 and the outside air can communicate with each other. Of a substance lost by sea water, such as a dissolvable member or substance that dissolves in sea water, a decomposable member or substance that decomposes by sea water, ).

When the ship navigation obstruction device 1 is dumped on the sea, the self-sinking device 6 causes the communication hole 17 to retain the seawater lost and lost item 18 until the lost and lost seawater item 18 is lost over a certain period of time. Since the marine vessel navigation obstruction device 1 is floated on the sea by the floating chamber 15 because it is closed, and the lost or lost seawater 18 is lost after a predetermined time, the communication hole 17 communicates with the outside air in the floating chamber 15. As a result, seawater flows into the floating chamber 15 through the communication hole 17, and a sufficient amount of seawater enters the floating chamber 15, whereby the ship navigation obstruction device 1 can be submerged in the sea. The functions that can be performed can be exhibited.

The communication hole 17 may be designed so that the inflow of seawater and the release of air in the floating chamber 15 are realized by the communication hole 17 itself. However, depending on circumstances, the floating chamber 15 may be provided in addition to the communication hole 17. It is also possible to separately provide an air vent (not shown) for venting the air inside.

An opening at the tip of the inner cylinder 10, that is, at the end on the warhead side, is closed by the warhead metal member 13. Further, the inside of the rear end portion of the inner cylinder 10 includes the warhead metal member 13 and a partition wall member 19 arranged in the inner cylinder 10 so as to be separated from the warhead metal member 13.
The gas discharge chamber 20 for strip release is formed. In the strip-eluting gas generation chamber 20, a strip gas generating source 21 for generating a gas amount and a gas pressure sufficient to discharge a plurality of strips 5 described later from the inner cylinder 10 to the outside is housed. I do. The strip gas generating source 21 is usually formed of explosive.

At the rear end of the housing body 7, the warhead metal member 13 and the warhead cap 14 form the battery housing 2.
2 are formed. The warhead cap 14 is provided with at least one, and usually a plurality of seawater inlets 23 so that seawater can flow into the battery accommodating chamber 22. The battery 3 disposed in the battery accommodating chamber 22 may be a member having a function of generating an electromotive force by seawater flowing into the inside from the seawater inflow port 23 provided in the warhead cap 14. May be a so-called seawater battery that generates an electromotive force when it comes into contact with, or a detecting means for detecting inflow of seawater, for example, a water detecting sensor, a switch for turning on a circuit by the detecting means, and a battery incorporated in the circuit. 3 can also be formed. The ship navigation obstruction device 1 shown in the drawing is equipped with a seawater battery.

Regardless of the configuration, the battery 3 is connected to a metal wire (not shown) that comes into contact with the strip gas generating source 21. Therefore, when a current flows through the metal wire by the electromotive force of the battery 3 generated by the inflow of seawater, the strip gas generating source 21 burns and explodes, and a plurality of high-pressure gases are generated from the inner cylinder 10. Can be thrown into the air.

A plurality of strips 5 are accommodated in the inner cylinder 10. As shown in FIG. 2, a cylindrical container 25 formed by a plurality of dividable cylindrical partial pieces 24 and a tip (end of the warhead side) opening of the cylindrical container 25 are covered. A plurality of throwing bodies, each of which includes the arranged separating plate 25A and a belt arranged in a wound state inside the cylindrical container 25 and having one end coupled to the inner cylinder 10 as one constituent unit, are arranged in a row. They are stacked and arranged in the inner cylinder 10.
The inner cylinder 1 that accommodates the plurality of throwing bodies in a stacked state
The rear end (the end on the breech side) of the zero is closed with an opening closing member for waterproofing or other purposes. In a state where the cylindrical containers 25 are stacked in the inner cylinder 10, a separation plate 25 </ b> A is provided between the cylindrical containers 25.
Is interposed. The separation plate 25A is pressed by the gas pressure generated by the strip gas generation source 21 to
5 functions as a piston plate for advancing the inside of the inner cylinder 10 toward the rear end thereof, and the wound strip 5 accommodated in the cylindrical container 25 is kept in the wound state.
It has a function to progress. In other words, if the separating plate 25A does not exist and the cylindrical containers 25 are merely stacked and the wound strips 5 are housed therein, the high pressure generated by the strip gas generating source 21 is generated. If the gas passes through the gap between the wound strips 5, the wound strip 5 cannot be efficiently advanced in the inner cylinder 10. There is a possibility that the strip 5 is loosened and the strip 5 discharged from the inner cylinder does not spread over a wide range.

The strip 5 in the present invention is thrown into the air from the inner cylinder 10 by the high-pressure gas generated by the strip gas generating source 21, and furthermore, with the ship navigation obstruction device 1 as a center (from another viewpoint). And centering on the inner cylinder 10)
Various configurations can be adopted as long as they can extend and float on the sea, and have a function of stopping the movement by being entangled with the screw of the ship. , Designed to have a length.

One design example of the strip 5 is as follows.
For example, a flat long tape having a predetermined width and length and formed to extend long on the sea can be mentioned. In addition, a long rope or a string designed to be able to be accommodated in the cylindrical accommodation body 25 and to extend long on the sea can be adopted.

The strip 5 has such a strength that it is not immediately cut by the screw but is entangled with the screw, and can be formed of a material floating on the sea. As such a material, for example, synthetic resin fibers such as high-strength nylon,
A preferred example is a blended material of a metal fiber and a synthetic fiber.

A breech member 8 is mounted on the rear end side of the housing body 7. The breech member 8 has a breech housing 26 having a tapered shape having a diameter attachable to the rear end of the outer cylinder 9, and the breech navigation device 1 when the marine vessel navigation obstruction device 1 falls in the air. An attitude control member, e.g., four arrow-shaped fins 27, which is formed upright on the outer surface of the breech housing 26 to control the posture in the vertical direction, is housed in the breech housing 26. And a breech-separating gas generation source 28.

The turret housing 26 has such a binding force that it can be easily released by the gas pressure generated from the breech release gas generating source 28. The outer cylinder is coupled to the rear end of the outer cylinder by a suitable coupling means having a coupling force that does not easily separate during operation and handling, such as a screw.

The breech release gas generating source 28 easily ignites and burns when a current is supplied by the electromotive force of the battery 3, and the breech member 8 can be released from the outer cylinder 9. As long as such a high-pressure gas is generated, it can be formed of various explosives.

The configuration of the breech release gas generating source 28 and the striation body gas generating source 21 may be determined so as to generate gas at the same time. A high pressure gas is generated from a gas generating source 28 to remove the staple member 8 from the outer cylinder 9.
The gas generation timing is adjusted such that high pressure gas is generated from the inner cylinder 10 and the plurality of strips 5 are thrown from the inner cylinder 10 into the air.

The operation of the ship navigation obstruction device 1 having the above configuration will be described. For example, on X / X / XX of the year 20XX,
It is assumed that a turbulent ship 29 sailing in the territorial waters of the Sea of Japan has been discovered. Following the ship 29, for example, a patrol ship 30
Issues a signal to stop, but suppose that the vessel 29 ignores this and starts retreating. The anti-ship patrol aircraft 31, which has been notified that the suspicious vessel 29 has been found, makes an emergency start and aims at the suspicious vessel 29.

As shown in FIG. 3, when the anti-ship patrol aircraft 31 discovers the suspicious vessel 29, it throws a plurality of vessel navigation obstruction devices 1 at the destination of the suspicious vessel 29. The landing position of the ship navigation obstruction device 1 is, as shown in FIGS. 3 and 4, on a line crossing the destination of the suspicious ship 29, and each landing position has a predetermined interval. Is good. The reason is that even if the suspicious vessel 29 makes a sharp turn to detect the landing of the vessel navigation obstruction device 1 and avoid the influence, it must collide with another vessel navigation obstruction device 1. That's why.

When the ship navigation obstruction device 1 falls in the air, the fin 27 serving as the attitude control device and the warhead metal member 13 existing on the warhead side are weighted, so that the ship navigation obstruction device 1 is dropped. Falls vertically straight down.

When the vessel navigation obstruction device 1 lands, as shown in FIG. 4, the buoyancy of the floating chamber 15 causes the warhead to sink below the surface of the sea and the breech to float with the breech exposed to the sea. . At this time, seawater flows into the inside from the seawater inlet 23 provided in the warhead cap 14 in the warhead.
An electromotive force is generated in the battery 3 by the inflowing seawater. A current flows through an electric wire connected to the battery 3 for generating an electromotive force and connected to the breech-separating gas generating source 28, and the breech-separating gas generating source 28 is ignited and burns to generate high-pressure gas. As a result of the high-pressure gas filling the breech housing 26, the breech member 8 is blown off from the outer cylinder 9 by the pressure as shown in FIG. 5.

The battery 3, which generates an electromotive force by seawater penetrating into the warhead cap 14, generates
1 flows, and the strip gas generation source 21 ignites and burns later than the firing and combustion of the breech separation gas generation source 28.
When the strip gas generation source 21 ignites and burns, high-pressure gas is generated. The high-pressure gas momentarily pushes up the strips 5 stored in the inner cylinder 10 in a stacked state. Usually, a cylindrical container 25 for accommodating the wound strip 5 is arranged on the partition plate 25A, and the opening of the cylindrical container 25 is covered with the next partition plate 25A. A plurality of cylindrical containers 25 are stacked in the inner cylinder 10 via the partition plate 25A in the order of disposing the next cylindrical container 25 on 25A. The high-pressure gas pushes up the cylindrical containers 25 and the partition plate 25A thus stacked. The partition plate 25A functions as a piston that is pushed by the high-pressure gas when moving in the inner cylinder 10, and a function that does not disturb the winding state of the strip 5 by leaking the high-pressure gas. Demonstrate.

As shown in FIG. 5, the plurality of strips 5 are blown into the air by the high-pressure gas while being stored in the cylindrical housing 25 from the inside of the inner cylinder 10. When blown from the inside of the inner cylinder 10, each cylindrical container 25 splits into a plurality of cylindrical partial pieces, and the internal strip 5 jumps out into the air. As shown in FIG. 4, one end of the strip 5 is connected to the housing 2, particularly to the inner cylinder 10, so that the strip 5 in a wound state is formed.
The wing flies in an arc in the air in such a manner that the roll is rewound, and finally, the tip of the strip 5 falls to the sea. When the tip of the strip 5 falls on the sea, for example,
As shown in FIG. 6, when viewed from above, the strips 5 extend radially over the sea around the housing 2.

As shown in FIG. 4, the suspicious ship 29
Are a plurality of strips 5 which are radially spread in this manner.
Proceed toward. When the vessel 29 passes through the radially extending strip 5, the strip 5 is entangled with the screw of the vessel 29, and the rotation of the screw is forcibly stopped, so that the vessel 29 can no longer be navigated. become.

The patrol boat 30 catches up with the stopped ship 29 and seizes it.

On the other hand, in the ship navigation obstruction device 1 in which the thread 5 does not become entangled with the screw, so to speak, since the outer cylinder 9 is equipped with the self-sinking device 6, a certain time elapses after landing. However, the marine vessel navigation obstruction device 1 does not sink, and does not hinder navigation of the following vessel.

That is, when the marine vessel navigation obstruction device 1 lands on the sea, the lost or lost seawater 18 loaded in the communication hole 17 provided in the outer cylinder 9 such as water-soluble dextrin, water-soluble synthetic resin, water-soluble Inorganic substances and the like are gradually dissolved by the seawater, and after a predetermined time, the entire amount of the lost and found seawater 18 has been dissolved, and as a result, the communication between the outside air and the floating chamber 15 becomes the communication strip 5 through the communication hole 17. Then, seawater flows into the floating chamber 15 through the communication hole 17. When seawater flows into the floating chamber 15 and the overall specific gravity of the ship navigation obstruction device 1 becomes larger than 1 due to the amount of seawater in the floating room 15, the ship navigation obstruction device 1 sinks in the sea, and Sinks. Therefore, the ship navigation obstruction device 1 does not become a floating matter on the sea and does not become an obstacle for the ship navigating on the sea, and does not cause natural destruction because it sinks to the sea floor.

Although one preferred embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and it goes without saying that the design can be appropriately changed within the scope of the present invention.

In this vessel navigation obstruction device 1, a plurality of strips 5 are connected at one end to the casing 2 of the vessel navigation obstruction apparatus 1, and a gas generating source 4, for example, a strip gas generating source 2
Is thrown into the air by the high-pressure gas generated by 1,
In addition, as long as it floats on the strip 5 that spreads as wide as possible on the sea, it is not necessary to be housed in the housing 2 in the wound state as described above. For example, the strips 5 may be housed in the cylindrical housing 25 as random strips 5. In this case, it is preferable to connect a “weight” to the tip end of the strip 5 having one end connected to the housing 2 so that it can be stably thrown in the air.

The number of cylindrical containers 25 for accommodating the strips 5 to be loaded into the inner cylinder 10 is not particularly limited, but should be as large as possible so as to entangle with the screw of the navigating ship. It is better to

The cylindrical container can accommodate a strip in a housing, and can release the inner strip into the air when the strip containing the strip is launched from the housing. It is sufficient if it is configured so that it can be formed, and it is not limited to the aggregate of the three-part cylindrical part pieces as in the above-described embodiment,
An appropriate configuration that includes a plurality of partial pieces and splits in the air can be employed.
