Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for forcibly stopping a moving body, such as a ship or a helicopter, that is propelled by a rotary wing without using a weapon.
[0002]
[Prior art]
Conventionally, a screw is generally used as a propulsion means for a ship. Our country is surrounded by the sea on all sides, and there are many suspicious ships that invade the territorial waters. For suspicious vessels discovered by patrol boats of the Japan Coast Guard and Self-Defense Forces escort vessels, a stop order is issued to stop the inspection. However, for a suspicious ship that escapes without following the stop instruction, it is necessary to stop and stop the suspicious ship. In that case, the officer will jump near the suspicious ship and stop the engine. Or, if necessary, intimidating and stopping.
[0003]
Recent suspicious ships are equipped with a high-power engine, so even if a suspicious ship is found, it is difficult to catch up. Even if a clerk jumps to the other ship and stops the ship's engine, the ship is stopped. That is difficult and dangerous. Also, if threatening shooting is performed, there is a risk that the other party will fire while giving the grounds for using the weapon to the other party.
[0004]
[Problems to be solved by the invention]
As described above, a suspicious high-speed ship that has entered the territorial waters is stopped without using a weapon. Jumping in is difficult and extremely dangerous. In addition, threatening shooting gives the opponent a basis for firing, which can be an international problem and cannot easily be used.
[0005]
The present invention is to forcibly stop a moving body by stopping the rotation of a moving body such as a rotor having a rotor blade used as a propulsive force, for example, a ship without using a weapon. It is to be an issue.

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the drawings. The cannonball 10 has a substantially conical tip, and a plurality of latching portions 20 can be opened and closed in a continuous cylindrical head cover 11. One end of the rope body 45 is connected to the rear end of the cylindrical portion 21 that is accommodated and provided in the latching portion 20. The weight 40 is connected to the other end of the rope, and the rear cover 15 which is also cylindrical and provided with a bottom is connected to the rear end of the head cover 11 to form a shell 10.
[0012]
An engaging recess 22 is formed in the upper peripheral surface of the cylindrical portion 21 located at the center of the latching portion 20, and a hole 23 for connecting one end of the rope body 45 is provided at the lower portion of the cylindrical portion. A movable shaft 25 is inserted into the upper portion of the cylindrical portion 21 so as to be movable up and down, and a protrusion 26 is provided on the rear peripheral surface of the movable shaft to be engaged with the locking recess 22 of the cylindrical portion 21.
[0013]
A ring 27 arranged around the movable shaft 25 supports the rear portions of a plurality of mounting pieces 28 arranged in the radial direction by fixing the front end to the peripheral surface of the movable shaft 25, and the ring 27 has a plurality of movable claws. A piece 31 is pivotably attached, and each movable claw piece 31 and attachment piece 28 are fixed to each other.
[0014]
When the movable claw piece 31 is accommodated in the head cover 11, it is closed in the central direction. However, when the head cover 11 is removed and the movable shaft 25 is retracted, the protrusion 26 is fitted into the locking recess 22 of the cylindrical portion 21 and the rear portion of the movable claw piece 31 is expanded in the circumferential direction. Each movable claw piece 31 is provided with a locking piece 32 formed in a substantially saw-tooth shape, and the rear part of the movable claw piece expands in the circumferential direction. Therefore, a structure provided on the hull (not shown) ) Will not slip off after locking.
[0015]
Reference numeral 35 denotes a support cylinder provided on the inner top of the head cover 11, and the support cylinder 35 is fitted to the upper end of the movable shaft 25. Reference numeral 36 denotes a plurality of support pieces for fixing the head cover 11 and the cylinder portion 21 in the radial direction. One end of the support piece is fixed to the lower peripheral surface of the cylinder portion 21, and the other end of the head cover 11 The head cover 11 and the latching portion 20 during flight are prevented from becoming unstable together with the support cylinder 35 by being fixed to the peripheral surface, and the target object is caused to fly accurately.
[0016]
The weight body 40 is formed in a conical shape to reduce resistance in water, and a stop portion 41 for connecting one end of the rope body 45 is provided at the front end of the weight body. A swirl vane 43 is attached to the lower peripheral surface of the weight body with a locking pin 42. When the weight body 40 is accommodated in the recess 16 of the rear cover 15, the swirl vane 43 is positioned in parallel with the longitudinal direction of the weight body 40 so as not to get in the way. When it departs from 15, the swirl vane 43 opens in the direction perpendicular to the resistance of water.
[0017]
Since the swirl blades 43 are provided with a twist angle on the entire surface, when the weight body 40 is connected to the rope body 45 and pulled under the sea by the ship, the weight of the center of the ship is greatly swung by the resistance of water. The swirl wave generated by the rotation of the screw located on the rear side is attracted to the screw side.
[0018]
The swirl blades 43 attached to the weight body 40 include a right-turn blade and a left-turn blade as required. The swirl blade is rotated by a vortex wave generated by the screw regardless of whether it is right-handed or left-handed. The net 45 is entangled with the screw 58 on the bottom of the ship, and the rotation of the screw is stopped.
[0019]
Next, a series of operations of the present apparatus will be described. As shown in FIG. 6, a moving body forced stop device 51 is equipped on a ship that tracks a suspicious ship, for example, a patrol boat 50. If a suspicious ship 55 is found during guarding, the mobile body forced stop device 51 is charged with a charge (not shown ) toward the suspicious ship 55 at a fixed distance while tracking the suspicious ship 55 that escapes without following the stop instruction. When the cannonball 10 loaded together is fired, it may be configured to separate the head cover 11 and the rear cover 15 after colliding with the hull, or after flying a certain distance, The separating glaze charged inside the joint portion between the part cover 11 and the rear cover 15 may be exploded and automatically separated.
[0020]
When the cannonball 10 falls on the deck 56 of the suspicious ship 55, which is the target, the movable shaft 25 moves back into the cylindrical body 21 due to the impact of the head cover 11 hitting the deck 56 due to the impact at the time of dropping. 26 is fitted into the engagement recess 22 of the cylindrical body 21, and at the same time, the rear portion of the movable claw piece 31 is expanded in diameter and hooked on a structure (not shown) on the deck 56. Since the protrusion 26 of the movable shaft 25 is fitted into the locking recess 22 of the cylindrical body 21 and the movable shaft 25 is fixed, the diameter of the movable claw piece 31 can be maintained.
[0021]
The latching force of the latching portion 20 is proportional to the traveling speed of the suspicious ship 55 and the hydraulic resistance of the weight body 40 that has fallen into the sea, and as long as the suspicious boat 55 is traveling, It is extremely difficult to remove it manually.
[0022]
On the other hand, the weight 4 0 accommodated in separate rear cover 15 is pulled in Tsunatai 45 which connects the hook portion 20 is routed through water. Furthermore, the swirl blade 43 attached to the weight body 40 swirls greatly due to the water resistance of the suspicious ship 55 that travels with the rope body 45. Since the swirl blade 43 is formed with a twist, the swirl blade 43 approaches the screw direction while largely swiveling the weight body 40 connected to the rear portion of the rope.
[0023]
As described above, the weight body 40 is guided by the rotation of the swirl vane 43. As shown in FIG. 7, in the case of the weight body 40 rotating rightward, the latching portion 20 is driven into the port side of the suspicious ship 55, In the case of a rotating weight body, by driving the latching portions 20 on the starboard side, the rope bodies 45 approach each other near the screw 58 on the bottom of the ship even if the suspicious ship 55 travels in a zigzag manner.
[0024]
The rope body 45 moved to the vicinity of the screw 58 is caught in the rotating vortex of the screw 58 and entangled with the screw shaft 57 and the screw 58 as shown in FIG. The rope body 45 entangled with the screw shaft 57 is wound around the screw shaft 57 to stop the rotation of the screw and stop the suspicious ship.
[0025]
When the rope body 45 is stretched substantially vertically just before the traveling direction of the helicopter 60 flying in the low sky, the rope body 45 is wound around the rotating shaft of the rotor 61 and entangled to stop the rotation of the rotor 61 and stop further flight. Let
[0026]
The length of the rope body 45 that connects the above-described latching portion 20 and the weight body 40 differs depending on the application, and is long enough to be entangled with the screw of the ship or the rotor of the helicopter (for example, about 20 to 50 m). It is. In addition, the rope 45 can use a wire rope, a piano wire, etc. other than a normal rope.
[0027]
Furthermore, since the mobile body forced stop device of the present embodiment is of an installation type and is large to some extent, it can be fired far away, so operability such as changing the firing direction is poor. Therefore, if the size is reduced to a rifle type, the firing direction can be freely changed, and a plurality of the present apparatuses can be fired simultaneously or with time, so that the ship stopping effect can be enhanced.
[0028]
【The invention's effect】
Since the present invention can stop the rotation of the screw of the moving body without using a weapon, it can be stopped safely.
[0029]
If a piano wire is used for the rope, the weight of the rope is light, so that the flight distance of the shell can be extended, and since the rope has strength, it can be stopped without fail.
[0030]
If it stops, the ship which is a moving body will drift on the surface of the water, and there is no danger of sinking and it can stop safely.
[0031]
Furthermore, in the case of other targets, for example, helicopters, a shell is fired on the front in the direction of flight, separating it into a hanging part and a weight, and the rope connected to the hanging part is moved vertically. By stretching, the rotation can be stopped by being entangled with the rotor of the helicopter. Therefore, it can be captured by an inexpensive and simple moving body stopping device.
