Description

The present invention relates to torpedo protection.

Ships now had no means of protecting themselves from torpedoes.

Allows a ship to protect itself from torpedoes by means of its own on board.

The present invention has been made in view of the above circumstances, and the object thereof is to:
Based on the information detected by the sonar provided by the ship, etc., the mine is moved and the net that entangles the torpedo and explodes is opened under the water surface in front of the torpedo's traveling direction.

An object of the present invention is to detect the movement of a torpedo by a ship, a ship and a mine, or a sonar attached to the mine, and to entangle the torpedo with a net to which the mine is attached and fixed, detonate the net, and detonate the net. To provide a mine characterized by opening under the water surface in front of the traveling direction of the torpedo and moving the entire net under the water surface using a screw or a propulsion device as required.

In short, the net has at least a sonar so that the traveling direction and position of the torpedo can be predicted and can be moved, making it easier to achieve the above object. And mines are attached and fixed to the net, and since the mines have a sonar inside, the distance between the equipment inside the mine and the sonar is shortened, so each mechanism is less likely to break down and can be fired faster. can get a reaction.

Further, the present invention is a mine having the net and detonating when entangled with a torpedo, wherein the mine is attached and fixed to the net, and the net is underwater using a screw or propulsion device. It will be a mine that is characterized by opening.

The mine having the net is characterized in that a plurality of mines are attached and fixed to the net. By equipping multiple mines with means of communication, the mines can understand each other's situation, and depending on the situation, the mines will explode by issuing an explosion command.

In addition, the mines installed in the net are characterized by incorporating a low-frequency generator or an electromagnetic wave generator, and each mine is equipped with a means of communication. They can communicate with each other and recognize each other's location information and other information. In addition, by incorporating a computer or electronic calculator into the mines installed in the network, information from devices such as sonar, low-frequency generators, electromagnetic wave generators, etc. can be efficiently calculated to efficiently calculate positions and the like. You can move to a certain position and open the net to get entangled in the torpedoes. The devices communicate and work together. By embedding a computer or an electronic calculator in the mine, it also manages each device built into the mine.

In addition, by increasing the specific gravity of multiple mines as the depth of the water increases, when the net is thrown into the water, it becomes difficult for the net to become entangled, increasing the positional stability.
And by incorporating a depth gauge into the mines, it was possible to recognize the position of each mine.

By having at least three or more mines 2 in the net, the torpedoes can be destroyed more reliably.
Also, by incorporating a speed sensing device into the mine, when it gets entangled in the torpedo, the speed of the mine increases and it can be made to self-explode when it senses it.

To provide a defense system characterized by putting at least a bomb in a mine equipped with waterproof means and opening the net so as to entangle the torpedo.

Another object of the present invention is to provide a defense system characterized by throwing a net equipped with three or more mines forward in the direction of torpedo movement, and opening the net so as to entangle the torpedoes.

A defense system characterized by opening the net so that the incident angle is 30 degrees or more with respect to the torpedo traveling direction.

The defense system as described above, wherein the installed bombs are detonated when the respective distances approach.

The mine is equipped with a built-in timer, so that when the set time comes, the equipped bomb can be disabled by self-destruction etc. By making it a defense system described above, the thrown mine is necessary. Since it did not explode after a certain amount of time, it did not harm other ships, etc., and safety was ensured.

In addition, the mine was characterized by having a battery inside, making it easier to operate each engine. And, by having antennas on the mines, it became easier to obtain information from the outside, and communication between mines became smoother. In addition, the timer, propulsion device, screw, sonar, low frequency generator, electromagnetic wave generator, and other described equipment are managed by a computer or a computer if a computer is built in. be done. However, if a computer or electronic calculator is not built in, the above devices are connected to each other and are designed to operate in an analog fashion.

The invention could protect ships from torpedo attacks.

A torpedo protection system according to the invention will now be described in detail with reference to FIGS.

FIG. 1 is a view of a mine 3 equipped with a net of the present invention, with a mine 2 open.

The mines 2 attached (attached and anchored) to the net 1 are each spaced apart.

The specific gravities of the mines 2a and 2b are set to be the same so that the mines 2a and 2c mounted on the net 1 arranged side by side are positioned horizontally with respect to the direction of the line of gravity.
In addition, the specific gravity of the mines, which are aligned vertically in the direction of gravity (on the vertical line), is smaller the higher they are positioned, and increases the lower they are positioned, making it difficult for the net to get entangled when thrown into the water. or
Mines lined up on the vertical axis in the direction of gravity (on the vertical line) are lighter the higher they are positioned, and heavier the lower they are positioned, making it difficult for the net to get entangled when thrown into the water. Alternatively, mines that are aligned vertically in the direction of gravity (on the vertical line) have a smaller specific gravity and heavier weight at the top, and a larger specific gravity and heavier weight at the bottom, so that they can be thrown into the water. It becomes difficult for the net to get entangled when it is packed.

In addition, the mines 2a and 2b mounted on the net 1 are positioned vertically in the direction of the line of gravity when they are opened. is doing.

Although not illustrated, mines 2 aligned vertically in the direction of gravity are made smaller as their specific gravity is higher. For example, the mine 2a is at the top, the mine 2b is below it, the mine 2k is below the mine 2b, and the mine 2n is below the mine 2k. The specific gravity of the mines 2 installed on the net 1 increases as they go down (specific gravity, mine 2a < mine 2b < mine 2k < mine 2n).

The mine 2 is a general term for mines, and the mines 2a, 2b, 2c, 2d, 2k, 2n, etc. are given alphabetical letters for easy explanation in the drawing.

It is desirable that the distance between each of the mines 2a, 2b, 2c, and 2d is 20 cm or more and 500 cm or less. Also, although not illustrated, the same applies to the case where the number of mines 2 is greater than the four shown in the drawing, or five or more. In the illustration, only 4 mines 2 are attached, but if you attach 9 and open them, you can expand the defense range, and if you attach 16 and open them, the defense range will be further expanded.

Figure 2 is a cross-sectional view of the mine 2. Antenna 11, torpedo detection sonar 12, explosive 13, battery 14, position retention system (a system for holding and moving the position of the mine, and propelling it to the target position). The means of propulsion includes a motor-operated screw) 15, a mine-to-mine communication system (a communication system based on electromagnetic waves in which mines sense each other's position, etc.) 16, a speed sensing device ( speed sensor) 17, central control unit 18, battery 19, depth gauge 20 (the depth gauge is equipped with a system that induces an explosion when it reaches a certain depth), and each device and engine communicates and senses each other. work purposefully.

In addition, each part and system built into the mine 2 are communicated and controlled by an electronic computer or a central control unit 18 controlled by a computer. explode and destroy. For example, the torpedo detection sonar 12 predicts the target torpedo progress and water depth, and the screw of the position holding system 15 or the propulsion device is used to move to the target location. Also, although not illustrated, mines are provided with a built-in timer.

Each mine 2 (in FIG. 1, mine 2a, mine 2b, mine 2c, and mine 2d) communicates with each other by a low-frequency communication system built into the mine-to-mine communication system, and based on that information, the position holding system Moves to open the net by operating the screw provided on the outside of the mine.

A screw (not shown) can freely change the direction of the water flow in order to hold and move the mine 2 at each position.

Devices and parts inside the mine are protected by a waterproof mine 2.

Other mine construction requirements not listed are the same as conventional mine construction. For example, a mechanism that explodes when a ship or torpedo touches a mine.

With this structure, based on the information of the torpedo 4 detected by the torpedo detection sonar and the information of each position of the mine 2 by the position detection sonar, each mine 2a, 2b, Locate 2c (Fig. 1).

FIG. 3 shows a net (torpedo protection system) equipped with mines 2 that are actually entangled with torpedoes 4 .

The mine 2 is designed so that when it is entangled in the torpedo by an internal or built-in speed sensing device 17, the speed of the mine 2 increases and self-explodes upon sensing it.

This destroys torpedo 4. In FIG. 3, mines 3 are attached to a net equipped with 25 mines 2 (5 horizontally by 5 vertically).

In addition, the amount of explosives contained in the mine 2 is enough to destroy the torpedo 4 with just one piece.

By setting the speed sensor of Mine 2 to 15 knots or more and triggering the detonator, the torpedo can be destroyed more reliably.

FIG. 4 shows the torpedo 4 before it gets entangled in the net 1.

The angle of incidence 6 on the net 1 is ideally 90 degrees, which is perpendicular to the traveling direction 5 of the torpedo 4. Set the system to , but set it as close to the ideal 90 degrees as possible.

In addition, the timer, propulsion device, screw, sonar, low frequency generator, electromagnetic wave generator, and other described equipment are managed by a computer or a computer if a computer is built in. be done. However, if a computer or electronic calculator is not built in, the above devices are connected to each other and are designed to operate in an analog fashion.

Said structure could protect the ship from torpedoes.
