Description

The present invention relates to protection from torpedoes.

Today, ships have no defenses to protect themselves from torpedoes.

Protect yourself from torpedoes by means that the ship carries it.

The present invention has been made in view of the above circumstances, and an object thereof is
Based on the information detected by the sonar provided by ships, etc., a net that has mines and entangles with torpedoes and explodes is opened under the surface of the water in front of the direction of travel of the torpedoes.

An object of the present invention is to explode a torpedo by entwining it with a net attached and fixed to the torpedo based on the information detected by a ship, a ship and a mine, or a sonar provided in the mine. It is intended to provide mines characterized by opening below the surface of the water in front of the torpedo's direction of travel and moving the entire net as needed.

Further, the present invention is a mine having the net and entwined with a torpedo to explode. The mine is attached to the net and fixed to the mine, and the net is opened by using a screw under the water surface. Make a mine.

The mine having the net is a mine characterized in that a plurality of mines are attached to and fixed to the net.

In addition, the mines installed in the network are made into mines characterized by being equipped with a low frequency generator, so that the mines can communicate with each other and be more efficient by the built-in electronic computer or computer. Calculate the target position, move to the efficient position, open the net and get involved in the mine.

Then, the net has at least three mines 2 to destroy the torpedo more reliably.

At least the bomb is placed in a mine equipped with waterproofing means, and the net is intended to provide a defense system characterized by opening to entangle with the torpedo.

Further, the present invention is to provide a defense system characterized in that a net equipped with three or more mines is administered forward in the torpedo traveling direction, and the net opens so as to be entwined with the torpedo.

The net is a defense system characterized in that it opens so that the incident angle is 30 degrees or more with respect to the torpedo traveling direction.

And the above-mentioned defense system characterized in that the installed bomb explodes when each distance approaches.

The above-mentioned defense system characterized in that the installed bomb is incapacitated when the set time comes.

According to the present invention, the ship can be protected from a torpedo attack.

It is a figure which looked at the present invention from the side. It is sectional drawing of this invention. It is a figure in which the net of this invention is entwined. It is a figure of the incident angle of this invention.

The torpedo protection system according to the present invention will be described in detail with reference to FIGS. 1 to 4.

FIG. 1 is a diagram in which a mine 3 provided in the net of the present invention is opened and the mine 2 is provided.

The mines 2 attached (attached and fixed) to the net 1 each have an interval.

The mines 2a and 2c provided on the side-by-side nets 1 are positioned laterally with respect to the direction of the gravity line, so that the mines 2a and the mines 2b have the same specific gravity.

Further, the mines 2a and 2b provided on the net 1 are located vertically in the direction of the gravity line when they are opened, and in order to easily realize this, the mines 2b have a larger specific gravity than the mines 2a. doing.

Although not illustrated, the mines 2 arranged on the vertical axis in the direction of gravity are made smaller as the specific gravity is higher. For example, with the mine 2a at the top, the mine 2b is below the mine, the mine 2k is below the mine 2b, and the mine 2n is below the mine 2k. The mine 2 provided in the net 1 has a higher specific gravity as it goes down (specific gravity, mine 2a <mine 2b <mine 2k <mine 2n).

Mine 2 is a general term for mines, and mines 2a, 2b, 2c, 2d, 2k, 2n and the like are given alphabets for easy explanation in the drawings.

The distance between the mines 2a, 2b, 2c and 2d is preferably 20 cm or more and 500 cm or less. Further, although not illustrated, the same applies to the case where the number of mines 2 is 5 or more, which is more than the 4 shown in the figure. In the illustration, only 4 mines are attached, but if you wear 9 mines and open them, you can expand the defense range, and if you wear 16 mines and open them, the defense range will be further expanded.

FIG. 2 is a cross-sectional view of the mine 2, which includes an antenna 11, a torpedo detection sonar 12, an explosive 13, a battery 14, and a position holding system (a system for holding and moving the position of a mine, for propelling it to a target position. The propulsion means include a screw for operating the motor) 15, a mine-to-mine communication system (a system in which mines detect each position) 16, a speed sensing device (speed sensor) 17 , Central control unit 18, battery 19, and depth gauge 20.

Each component and system built into the mine 2 are contacted and controlled by a central control unit 18 controlled by a computer or a computer, and the net is controlled so as to entangle the torpedo, and when entangled. Explodes and destroys. For example, the torpedo detection sonar 12 predicts the desired torpedo progress and water depth, and moves to the target location using the screw of the position holding system 15.

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

The screw not illustrated can freely change the water flow direction in order to hold and move each position of the mine 2.

The devices and parts inside the mine are protected by the waterproof mine 2.

The structure required for other unwritten mines is the same as the conventional mine structure. For example, a mechanism that explodes when a ship or torpedo comes into contact with a mine.

Based on the information that the torpedo 4 was detected by the torpedo detection sonar and the information that the position of each mine 2 was detected by the position detection sonar by this structure, the respective mine 2a, 2b, by the position holding system equipped with the screw, Position 2c (Fig. 1).

FIG. 3 is a diagram in which a net (torpedo defense system) equipped with a mine 2 that is actually entwined with the torpedo 4 is entwined.

The mine 2 is designed so that when the torpedo is entangled with the torpedo by the built-in speed sensing device 17, the speed of the mine 2 increases and the mine 2 senses the speed and explodes.

This destroys the torpedo 4. In FIG. 3, a mine 3 attached to a net in which 25 mines 2 are provided by 5 in the horizontal direction and 5 in the vertical direction is used.

The amount of explosive of the mine 2 is built in so that even one mine can destroy the torpedo 4.

By setting the detection of the speed sensor of the mine 2 to 15 knots or more and activating it on the detonator, the torpedo can be destroyed more reliably.

FIG. 4 is a view before the torpedo 4 is entangled with the net 1.

Ideally, the incident angle 6 with respect to the net 1 is 90 degrees, which is perpendicular to the traveling direction 5 of the torpedo 4, but since at least 30 degrees is required, the system of the mine 2 is used within this range. Set the system to, but set it as close to the ideal 90 degrees as possible.

The structure was able to protect the ship from torpedoes.
