Description

[Technical Field]

[0001] The present invention relates to torpedo protection. [Background technology]

[0002] Nowadays, ships had no means of protecting themselves from torpedoes. DISCLOSURE OF THE INVENTION [Problem to be solved by the invention]

[0003] Allows ships to protect themselves from torpedoes with their own onboard means.

[0004] The present invention has been made in view of the above circumstances, and its object is to Based on information detected by sonar on ships, the mines are moved and a net that entangles the torpedo and explodes is opened underwater in front of the torpedo's direction of travel. [Means for solving the problem]

[0005] The object of the present invention is to provide a mine that, based on information about the movement of a torpedo sensed by sonar installed on a ship, a ship and a mine, or on the mine, entangles the torpedo in a net attached to it and explodes, opens the net underwater in front of the torpedo's direction of travel, and, if necessary, moves the entire net underwater using a screw or propulsion device.

[0006] In other words, by having at least a sonar, the net can predict the direction and position of the torpedo and move, making it easier to achieve the above purpose.The mines are attached and fixed to the net, and by having a sonar inside them, the distance between the equipment inside the mine and the sonar is shortened, making each mechanism less likely to malfunction and allowing for a faster response.

[0007] The present invention also provides a mine that has the above-mentioned net and explodes after entangling a torpedo, wherein the mine is attached and fixed to the net, and the net opens underwater using a screw or a propulsion device. The net may also be a mine that moves underwater using a screw or a propulsion device.

[0008] The mine with the net is characterized by a plurality of mines attached and secured to the net, and the plurality of mines are equipped with communication means for communicating with each other, allowing them to understand each other's situations, and the mines can be commanded to explode depending on the situation.

[0009] Furthermore, by making the mines attached to the nets characterized by being equipped with low-frequency generators or electromagnetic wave generators, each mine can communicate with each other by being equipped with communication means and recognize each other's position information and other information. Furthermore, by incorporating a computer or electronic calculator, the mines attached to the nets can calculate the most efficient position based on information from devices such as sonar, low-frequency generators, and electromagnetic wave generators, move to an efficient position, open the net, and entangle the torpedoes. Each of the above devices communicates and works together.

[0010] In addition, by increasing the specific gravity of multiple mines the deeper they are, when the net is thrown into the water, it is less likely to get tangled, and its positioning becomes more stable. Furthermore, by incorporating depth gauges into the mines, the location of each mine could be identified.

[0011] Furthermore, the net has at least three or more mines 2, which makes it more likely to destroy torpedoes.

[0012] The object of the present invention is to provide a defense system characterized in that at least a bomb can be placed in a mine equipped with a waterproof means, and the net opens to entangle the torpedo.

[0013] The present invention also provides a defense system characterized by deploying a net equipped with three or more mines ahead of the torpedo in the direction of travel, and the net opens to entangle the torpedo.

[0014] The net is a defense system characterized by opening at an angle of 30 degrees or more relative to the direction of torpedo travel.

[0015] The defense system described above is characterized in that the bombs installed therein explode when they come close to each other.

[0016] By using the defense system described above, which is characterized by the fact that the mines are equipped with built-in timers and the bombs equipped can be set to be neutralized when the set time comes, the thrown mines are set not to explode if the required time has passed, or the explosion is induced when the time comes, so that even if other ships etc. get caught in the net, they will not be harmed, and safety can be ensured.

[0017] Furthermore, mines feature internal batteries, making it easier to operate each engine. Furthermore, mines have antennas, making it easier to obtain information from outside and facilitating communication between mines. Furthermore, mines have a net that entangles a torpedo and explodes, and the mine is attached and fixed to the net. The mine attached to the net uses a screw to open the net, and a case for containing the net may be provided. The case may open after being launched into the water, releasing the net it contains. Furthermore, if a computer or electronic calculator is built in, the timer, propulsion device, screw, sonar, low-frequency generator, electromagnetic wave generator, and other described devices are managed by the computer or electronic calculator. However, if a computer or electronic calculator is not built in, the above devices are connected to each other and are designed to operate analogically.

[0018] The present invention proposes a torpedo defense system comprising a net, a plurality of mines attached to the net, and a plurality of moving devices attached to the net, each having a propulsion generating means for generating a water current and generating propulsion, and a direction changing means for changing the direction of movement, and capable of moving in any direction underwater.

[0019] The above-mentioned torpedo defense system may also be configured to include a case that houses the net, the mines, and the moving devices, and the case opens after being launched into the water, releasing the net, the mines, and the moving devices into the water. According to this torpedo defense system, the mines for detonating torpedoes can be quickly moved to the torpedo capture position. The moving devices here refer to screws or propulsion devices. The proposed mines are attached and fixed to the net, and the mines attached to the net are moved or opened underwater using the screws or propulsion devices. The proposed mines are housed in a case 21. The case also includes a missile or rocket having a space capable of storing the net. [Effects of the Invention]

[0020] This invention could protect ships from torpedo attacks. [Brief explanation of the drawings]

BEST MODE FOR CARRYING OUT THE INVENTION

[0022] The torpedo protection system according to the present invention will now be described in detail with reference to FIGS.

[0023] FIG. 1 shows a diagram of a mine 3 attached to a net of the present invention, opened, and equipped with a mine 2.

[0024] The mines 2 provided (attached and fixed) to the net 1 each have a spacing.

[0025] The mines 2a and 2c attached to the horizontally arranged net 1 are positioned horizontally relative to the direction of the gravity line, so that the specific gravity of the mines 2a and 2b is the same. And, by arranging the mines vertically in the direction of gravity (on a vertical line), the specific gravity is smaller at the top and larger at the bottom, so that the net is less likely to get tangled when thrown into the water. Mines lined up on a vertical axis in the direction of gravity (a vertical line) are lighter at the top and heavier at the bottom, making them less likely to get tangled in a net when thrown into the water. Alternatively, mines lined up on a vertical axis in the direction of gravity (a vertical line) are lighter and heavier at the top, making them less likely to get tangled in a net when thrown into the water.

[0026] Furthermore, when the mines 2a and 2b attached to the net 1 are opened, they are positioned vertically in the direction of the gravity line, and to easily achieve this, the mine 2b has a greater specific gravity than the mine 2a.

[0027] Although not illustrated, the specific gravity of the mines 2 arranged vertically in the direction of gravity decreases the higher they are positioned. For example, with mine 2a at the top, mine 2b below it, mine 2k below mine 2b, and mine 2n below mine 2k, the specific gravity increases the further down the vertical axis they go. The specific gravity of the mines 2 attached to net 1 increases the further down they go (specific gravity, mine 2a<mine 2b<mine 2k<mine 2n).

[0028] Furthermore, mine 2 is a general term for mines, and mines 2a, 2b, 2c, 2d, 2k, 2n, etc. are numbered alphabetically to make them easier to explain on the drawings.

[0029] The distance between mines 2a, 2b, 2c, and 2d should preferably be between 20cm and 500cm. Although not illustrated, the same rule applies if there are more than four mines 2 than the four shown in the diagram, or five or more. While only four mines 2 are shown in the diagram, the defensive range can be expanded by attaching and opening nine, and by attaching and opening 16, the defensive range can be further expanded.

[0030] Figure 2 is a cross-section of a mine 2, and includes an antenna 11, a torpedo-detecting sonar 12, explosives 13, a battery 14, a positioning system (a system for maintaining and moving the mine's position, and equipped with a means for propelling it to the desired location. The propulsion means includes a motor-driven screw) 15, a mine-to-mine communication system (a communication system using electromagnetic waves that allows mines to sense each other's positions, etc.) 16, a speed sensor 17, a central control unit 18, a battery 19, and a depth gauge 20 (the depth gauge is equipped with a system that induces an explosion when a certain depth is reached). Each device and engine communicates with and senses the others, and functions according to its purpose.

[0031] Each component and system built into the mine 2 communicates and is controlled by a central control unit 18 controlled by a computer, which controls the net to entangle the torpedo and explodes when it does. For example, the torpedo detection sonar 12 predicts the target torpedo's progress and water depth, and the positioning system 15 uses a screw or propulsion device to move to the target location. Although not shown, the mine is also equipped with a built-in timer.

[0032] Each mine 2 (in Figure 1, mine 2a, mine 2b, mine 2c, and mine 2d) communicates with each other using a low-frequency communication system built into its own mine-to-mine communication system, and based on this information, the positioning system operates the screws on the outside of the mine to open the net.

[0033] In addition, the screws (not shown) can freely change the direction of the water flow to maintain and move the positions of each mine 2.

[0034] The equipment and parts inside the mine are protected by a waterproof mine 2.

[0035] The other structures required for mines that are not mentioned are the same as those of conventional mines, such as a mechanism to explode when a ship or torpedo comes into contact with the mine.

[0036] With this structure, based on the information of torpedo 4 detected by the torpedo detection sonar and the information of the position of each mine 2 by the position detection sonar, each mine 2a, 2b, 2c (Figure 1) is positioned by a positioning system equipped with screws.

[0037] Figure 3 shows a net (torpedo defense system) equipped with mines 2 entangled against an actual torpedo 4 .

[0038] Mine 2 is designed so that when it gets entangled with a torpedo, its speed increases due to the speed detection device 17 installed inside, and it detects this and self-destructs.

[0039] This destroys torpedo 4. This diagram 3 shows mine 3 attached to a net with 25 mines 2 arranged in a 5 by 5 row.

[0040] Furthermore, one mine 2 contains enough explosive to destroy torpedo 4.

[0041] By setting Mine 2's speed sensor to detect speeds of 15 knots or more and activating the detonator, the torpedo can be destroyed more reliably.

[0042] FIG. 4 shows the torpedo 4 before it becomes entangled in the net 1.

[0043] The angle of incidence 6 of the net 1 relative to the direction of travel 5 of the torpedo 4 is ideally 90 degrees, but since it needs to be at least 30 degrees, the system of the mine 2 is used and set within this range, but it is set as close to the ideal 90 degrees as possible.

[0044] Furthermore, the timer, propulsion device, screw, sonar, low frequency generator, electromagnetic wave generator, and other described devices are managed by a computer or electronic computer when they are built in. However, when a computer or electronic computer is not built in, the devices are connected to each other and are designed to operate in an analog manner.

[0045] In the embodiment described above, the mines 3 attached to the net of the present invention are housed in a bullet-shaped case 21 and launched from a launching device 26. Each of the plurality of mobile devices 12 is launched from a launching device 26. Alternatively, a plurality of mines 3 attached to the net of the present invention may be housed in a bullet-shaped case 21, and the case 21 containing the mines 3 attached to the net of the present invention may be housed in the case 21 and launched by a launching device.

[0046] FIG. 5 is a diagram showing a schematic view of the appearance of injection device 26 according to this modified example and case 21 loaded in the injection tube of injection device 26.

[0047] The launching device 26 launches the case 21 containing the mine 3 attached to the net of the present invention into the water using the force of a spring, compressed air, etc. The case 21 also includes missiles and rockets that have space capable of storing the mine 3 attached to the net of the present invention.

[0048] (0085) 6 is a diagram showing the appearance of the case 21. The case 21 has a bullet shape as a whole. The case 21 comprises a first part 211 and a second part 212 that are separable.

[0049] 7 is a diagram showing the appearance of the first part 211 and the second part 212. The first part 211 and the second part 212 each have the shape of a bullet cut in two, and have a space inside for accommodating the mine 3 attached to the net.

[0050] A plurality of convex portions 2111 are provided on surface S1, which is the surface where first part 211 comes into contact with second part 212. A plurality of concave portions 2121 are provided on surface S2, which is the surface where second part 212 comes into contact with first part 211. When first part 211 and second part 212 are connected, convex portions 2111 fit into concave portions 2121, thereby positioning first part 211 and second part 212.

[0051] A battery and an electromagnet are housed in base 2112 of first part 211. The electromagnet housed in base 2112 generates magnetic force using power supplied from the battery, and magnetizes a magnetic material (for example, iron) arranged on surface S1 of first part 211 to the south pole.

[0052] A battery, an electromagnet, an acceleration sensor, a timer, and a switch are housed in base 2122 of second part 212. The electromagnet housed in base 2122 generates magnetic force using power supplied from the battery, and magnetizes a magnetic material (for example, iron) arranged on surface S2 of second part 212 to the north pole or south pole.

[0053] (0090) When the acceleration sensor detects acceleration equal to or greater than a predetermined threshold value that occurs when case 21 is ejected from ejection device 26, it outputs a signal to the timer. The timer measures the elapsed time from the time it receives the signal from the acceleration sensor, and when a predetermined time (e.g., 5 seconds) has elapsed, it outputs a signal to the switch. When the switch receives the signal from the timer, it switches the polarity of the magnetic force generated by the electromagnet.

[0054] The electromagnet housed in base 2122 of second part 212 magnetizes the magnetic material arranged on surface S2 to the north pole when case 21 is loaded into injection device 26. Therefore, surface S1 of first part 211 and surface S2 of second part 212 attract each other and are connected by magnetic force.

[0055] When a predetermined time has elapsed after case 21 is ejected from ejection device 26, a switch housed in base 2122 of second part 212 switches the polarity of the magnetic force generated by the electromagnet, and the magnetic material disposed on surface S2 is magnetized to the south pole. As a result, surface S1 of first part 211 and surface S2 of second part 212 repel each other due to the magnetic force, and first part 211 and second part 212 are separated.

[0056] Figure 8 is a diagram showing the release of the contained mines 3 attached to the net of the present invention into the water after the case 21 has been launched from the launching device 26. Note that part of the mines 3 attached to the net of the present invention is omitted in Figure 8. After the case 21 has been launched from the launching device 26, when a predetermined time has passed, the first part 211 and the second part 212 separate, and the mines 3 attached to the net housed in the case 21 are released into the water. The mines 3 attached to the net of the present invention that have been released into the water spread out in the water, preparing to capture torpedoes.

[0057] In this modified example, the first part and the second part may be connected and disconnected using a force other than magnetic force. For example, the first part and the second part may be connected and disconnected by an electric actuator. Furthermore, the number of parts constituting the case 21 is not limited to two. For example, the case 21 may be composed of three or more parts, and these parts may be separated after ejection.

[0058] According to this modification, the mine for detonating the torpedo can be quickly moved to the torpedo capture position.

[0059] Furthermore, the timer, propulsion device, screw, sonar, low frequency generator, electromagnetic wave generator, and other described devices are controlled by a computer or electronic computer if they are built in. However, if a computer or electronic computer is not built in, the devices are connected to each other and are designed to operate in an analog manner.

[0060] This structure provided protection for the ship from torpedoes. [Explanation of symbols]
