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 mounted on the mine, and based on the information detected, the mine is attached to a fixed net, and the mine is entangled in the torpedo and explodes, causing the net to explode. To provide a mine characterized by opening under the water surface in front of the advancing direction of the torpedo and moving the entire net under the water surface using a screw or a propulsion device as required.

In short, since the net has at least a sonar, the traveling direction and position of the torpedo can be predicted and moved, so that the above object can be easily achieved. The mines are attached to the net and fixed, and the mines have a sonar inside, so 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 by being entangled in 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.

Further, the mines installed in the net are equipped with low-frequency generators or electromagnetic wave generators. can recognize 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.

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.

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.

Further, 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 mines are equipped with a built-in timer so that the equipped bombs can be set to be incapacitated at the set time. Since it did not explode when it passed, 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.

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 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 in 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, which includes an antenna 11, torpedo detection sonar 12, explosives 13, batteries 14, and a position holding system (a system for holding and moving the position of the mine. The means of propulsion includes a motor-operated screw) 15, a mine-to-mine communication system (a communication system using electromagnetic waves in which mines sense each other's position) 16, a speed sensing device ( A speed sensor) 17, a central control unit 18, a battery 19, and a water depth gauge 20, and each device and engine communicate and sense each other and work according to the purpose.

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 through 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 illustrated) 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 of the mines 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 with the torpedo by the 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.

Said structure could protect the ship from torpedoes.
