Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underwater vehicle defense device for a surface watercraft.

[0002]

2. Description of the Related Art Conventionally, as means for defending an underwater vehicle of a surface watercraft, for example, as shown in the side view of FIG. 5, a collision with an underwater vehicle 02 tracking an surface watercraft 01 by an external operation. To avoid this, the towing tool 04 that is towed from the stern via the cable 03 generates the same sound wave as that generated by the watercraft 01, and guides the underwater vehicle 02 toward the towing tool 04. Things are known. In this type of means, FIG.
As shown in the partially enlarged view, the base end portion of the cable 03 has a hoisting machine 06 arranged at the stern portion of the upper deck 05 of the watercraft 01.
The center part passes through the opening 08 of the stern end wall structure 07, and the tip part extends into the water.

However, such means have the following drawbacks. (1) When the sound wave from a third party such as underwater noise is strong, the action of guiding the underwater vehicle 02 toward the towing tool 04 is reduced, so that the underwater vehicle 02 cannot be avoided. Therefore, the reliability of defense is not sufficient. (2) Towing equipment 04 is expensive because it has built-in electronic equipment.
Collision with the underwater vehicle 02 and total loss results in high costs and is therefore uneconomical. (3) If the first defense is successful and the underwater tow tool 04 is completely damaged, use the hoist 06 to prepare the cable 0 for the next defense.
Although a new tow tool 04 is connected to the tip of 3, the work is troublesome and considerably troublesome, so the tracking of the underwater vehicle 02 cannot be prevented during that time, and therefore continuous defense is impossible. Not practical enough.

[0004]

DISCLOSURE OF THE INVENTION The present invention has been proposed in view of such circumstances, and is not damaged by underwater noise or the like, does not cause total loss, and enables continuous protection. Therefore, it is an object of the present invention to provide an underwater vehicle defense device for a surface watercraft that is highly reliable, economical and practical.

[0005]

To this end, the present invention is provided with a plurality of floats provided at appropriate intervals along the upper end and a plurality of weights provided at appropriate intervals along the lower end and the left and right ends, respectively. A plurality of underwater vehicle capture wire nets each having a self-propelled float for spreading, and a plurality of wire mesh nets arranged in parallel at the stern end of a surface watercraft, each of which is stored in a folded state in advance and a lid is provided as necessary. And a plurality of wire-mesh drop boxes for catching the underwater vehicle that is being tracked by dropping the stored wire-mesh to the rear water surface of the surface watercraft.

[0006]

According to this structure, a plurality of floats attached at appropriate intervals along the upper end, a plurality of weights attached at appropriate intervals along the lower end, and self-propelling for extension attached to the left and right ends respectively. A plurality of underwater vehicle capture wire nets each having a float, and a plurality of wire nets installed side by side at the stern end of a surface watercraft, each of which is stored in a folded state in advance and stored by opening the lid as necessary. Since a plurality of wire mesh dropping boxes for catching the underwater vehicle to be tracked by dropping the captured wire meshes to the rear water surface of the surface watercraft are provided, the following operation is performed. (1) The surface of the underwater vehicle can be spread by the surface of the underwater vehicle in a planned manner, and the device becomes active. (2) The capture wire mesh will not be damaged even if it collides with the underwater vehicle, and it can be reused if recovered. (3) The catching wire net can be continuously dropped onto the water surface at a relatively short time interval, which enables continuous protection.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, an embodiment of the present invention will be described. The same reference numerals as those in FIGS. 5 to 6 designate the same members, respectively. First, in the perspective view of FIG. Reference numeral 1 denotes a plurality of wire mesh dropping boxes for catching underwater vehicles, which are vertically projected on the water surface WL of the stern end wall-like outer plate 2 of the watercraft 01 and extend in the left-right direction. A hinge lid 3 that opens to the left is pivotally attached, and a rectangular capture wire net 4 is stored inside in a folded state. As shown in the enlarged view of FIG. 3, reference numerals 5 are self-propelled floats respectively attached to the upper left and right ends of the capture wire net 4, which drive a motor 7 by a battery 6. Reference numeral 8 (FIG. 4) is a plurality of floats attached between the self-propelled floats 5 of the capture wire net 4 at appropriate intervals, and 9 is a weight attached to the lower end of the capture wire net 4 at appropriate intervals.

In such a device, the underwater vehicle 02
In order to avoid tracking due to
As shown in (1), when the watercraft 01 detects the tracking of the underwater vehicle 02, the watercraft 01 follows the course of the underwater vehicle 0.
After turning so that it almost coincides with the course of 2, the hinge lid 3 of the wire net dropping box 1 is opened, and the wire net 4 for catching is automatically dropped into the water by using gravity, and its self-propelled buoyancy 5,5 Are self-propelled in the direction orthogonal to the course of the underwater vehicle 02, and as shown in FIG. 2B, the catching wire net 4 is extended in the direction orthogonal to the course of the watercraft 01. Then, the underwater vehicle 02 is caught by the catching wire net 4 and the speed thereof is sharply reduced, and the course of the underwater vehicle 02 is deviated, so that the surface watercraft 01 can avoid the tracking of the underwater vehicle 02.

According to the apparatus of this embodiment, a plurality of floats provided at appropriate intervals along the upper end and a plurality of weights provided at appropriate intervals along the lower end and the left and right ends are provided respectively. A plurality of underwater vehicle capture wire nets each having a self-propelled float for spreading, and a plurality of wire mesh nets arranged in parallel at the stern end of a surface watercraft, each of which is stored in a folded state in advance and a lid is provided as necessary. Since the plurality of wire mesh dropping boxes for catching the underwater vehicle that is opened and stored to drop the catching wire nets to the rear water surface of the surface watercraft for tracking are provided, the following effects can be obtained. (1) The surface of the underwater vehicle can be spread by the surface of the underwater vehicle in a planned manner, and the device can be activated.
Therefore, the reliability of the device is improved. (2) The capture wire net will not be totally damaged even if it collides with the underwater vehicle, and it can be reused if it is recovered, thus improving the economical efficiency. (3) The capture wire net can be continuously dropped onto the water surface at a relatively short time interval, which enables continuous protection, thus improving the practicality of the device.

[0010]

In summary, according to the present invention, a plurality of floats provided at appropriate intervals along the upper end, a plurality of weights provided at appropriate intervals along the lower end, and a self-extending device attached to the left and right ends, respectively. A plurality of underwater vehicle capture wire nets each having a buoy and a plurality of wire nets installed side by side at the stern end of a surface watercraft, each of which is stored in a folded state in advance and the lid is opened as necessary. It is equipped with multiple wire-mesh drop boxes that catch the underwater vehicle that is tracking it by dropping the stored wire-mesh to the rear water surface of the surface watercraft. Therefore, the present invention is extremely useful industrially because it provides a submersible vehicle protection device for a surface watercraft that is capable of continuous protection and is therefore highly reliable, economical, and practical. is there.
