Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for disposing of a minefield by deploying it over the minefield and detonating the mine.

Conventionally, this type of device includes an explosive cable type device as disclosed in Japanese Patent Publication No. 48-35320. This type uses a structure in which the front end of a long bag-shaped explosive cable loaded with explosives is connected to a rocket, and the rear end is connected to a brake cable using a rubber cable or the like. When using it, drive a stake in front of the destination point and tie the brake cable to it, then fire the rocket and let the explosive cable pass through it, and when the brake cable reaches its full length along with the explosive cable, the rocket will launch. By being braked and falling, the detonating cord is deployed in a straight line, and the detonating cord is then detonated to detonate the landmine.

However, this conventional method has disadvantages in that it lacks power and has a large range restriction.

In other words, since the explosive cord is like the one mentioned above, the explosive is dispersed over a long distance, and the blast pressure is also dispersed accordingly, so it is necessary to fully demonstrate the power compared to the amount of explosive. If a thick explosive cable with a large amount of explosives is used as a countermeasure, it becomes necessary to increase the speed of the rocket, especially the initial velocity, and a large tensile force is applied to the explosive cable due to acceleration. As a result, the increase in drug dosage is constrained by this aspect. If the brake cable is lengthened, the same problem as above will occur due to the increased weight, and the firing range will also be restricted.

Therefore, in order to exert sufficient power with this method, it was necessary to deploy multiple systems of explosive cables, as well as transporting the bomb to the launch point and laborious work at that point.

In view of the above background, the present invention is constructed as follows with the aim of providing a minefield disposal device that can effectively detonate landmines and is not subject to range limitations. That is, (1) A plurality of explosive blocks each having an explosive case loaded with explosives and each having a detonator that detonates at a synchronized timing upon receiving a predetermined detonation signal are connected in series with a rope, and at least the last The connected structure of the explosive blocks connected to the air resistance body is housed in a cylindrical container, and the air resistance body is placed in the rear end of the container. A configuration in which a rocket motor is attached to the container as well as a means for ejecting the body.

(2) A plurality of explosive blocks, each consisting of an explosive case loaded with explosives and each having a detonator that detonates at a synchronized timing upon receiving a predetermined detonation signal, are connected in series with a rope, and at least A connected structure of explosive blocks in which a parachute that applies braking during flight is connected to a certain explosive block, and a parachute that has a towing function is connected to the most forward explosive block.
A structure in which longitudinally divided segments are releasably connected and housed in a container, and the container is provided with means for releasing the connection and a rocket motor.

Hereinafter, for convenience, the components (1) and (2) will be referred to as a minefield clearance rocket device.

An example will be explained.

FIG. 1 and FIG. 2 show the explosive device for disposing of the mine field, and both show the state immediately before landing.

In the explosive device shown in FIG. 1, reference numeral 11 denotes a plurality of explosive blocks, each of which consists of an explosive case loaded with explosives, to which a detonator is attached. A hook 12 fixed to the top surface of the explosive case is hooked to a series of ropes 13, which connect a plurality of explosive blocks 11 in series, and the ropes 13 are made of flexible wire rope or nylon. A rope or the like is used. A parachute 15 as an air resistance element is connected to the hook of the last explosive block 11a. Furthermore, the explosive block forms an easily destructible part on the opposite side of the hook 12, that is, on the bottom surface of the explosive case, and a suitable number of the explosive blocks (all in the embodiment) are provided with another air having a lower air resistance than the parachute 15. A resistor, for example, an air resistance plate 17 made of a resin film stretched over a ring-shaped frame, is attached via several hanging cords 14. Reference numeral 18 denotes a detonation timer, which is hooked to the front end of the rope 13 and has an air resistance plate 17 similar to that described above attached thereto. This detonation timer 18 generates an electric signal when a predetermined time elapses after activation.
It transmits a detonation signal such as a shock wave signal, and this detonation signal is transmitted to the detonator via a signal transmission line (not shown) loosely placed along the rope 13, thereby causing each explosive block to be activated. Detonate in unison.

Next, in the explosive device shown in FIG. 2, reference numeral 31 denotes a plurality of explosive blocks, and hooks 32 and easily destructible parts are provided on the upper and lower surfaces of the explosive case, respectively, in the same manner as described above, and on both sides of the explosive case. Another hook 34 is fixed to the top, and a plurality of explosive blocks 31 are connected in series using these hooks 34 and a rope 33. Parachutes 35a and 35b are connected to the hooks 32 of the rearmost and foremost explosive blocks 31a and 31b, respectively, and in the embodiment, parachutes 35 are similarly connected to the other explosive blocks.

In these cases the rearmost parachute 3
It is desirable to make the parachute 5a larger than the others, or to make the front parachute 35b or the next parachute 35c smaller than the others. 38 is a detonation timer similar to the above, interposed between the parachute 35a and the explosive block 31a.

1 and 4 mainly illustrate the minefield disposal rocket device which accommodates the explosive device of the embodiment shown in FIG.

In the figure, 51 is a cylindrical container, 53 and 71 are the front and back lids of the container, respectively, and 55
4 rocket motors are fastened to the rear of the container by tightening means 57, 59 is a tail fixed to the rear of the container, and 61 is a slipper for engaging with the rail of the launch pad. The explosive device is stored in a parachute 15 at the rear as shown below.

That is, the detonation timer 18 is housed in a housing 54 formed on the forehead 53, and the elastic ring 5
6 holds the outer periphery tightly, and this tension is set to such an extent that the timer will not slip out due to the inertial force upon firing.

The explosive block 11 is inserted into the explosive case 19 by sequentially inserting the hook 12 toward the rear.
The container 51 has three ribs 21 protruding from the outer periphery of the container 51.
A gap 63 is formed between them, and the rope 13 is connected to each hook 12 through the gap. still,
In explosive block 11, 20 is explosive case 1
The easily destructible part is formed by forming the bottom plate 9 thin as a whole, 23 is the detonator attached to this easily destructible part, and 22 is an explosive.

Further, 25 is an easy-to-break band for holding together the ropes 13, and 65 is a spacer placed on both sides of each explosive block. , restricts the back and forth movement of the explosive block, and splits and falls when pulled out of the container.

Reference numeral 70 denotes a discharge means for an air resistance body (parachute 15) constructed at the rear end of the container, which is connected to the rear lid 7.
1, a gunpowder-type breaking bolt 72 that fastens this rear lid to the tail end of the container 51, a pilot parachute 73 arranged inside the rear lid 71 and connected to the umbrella head of the parachute 15, and a pilot parachute 73 that is attached to the rear lid. It is composed of a fitted release timer 75 and the like, and the output terminal (not shown) of the release timer 75 is removable and electrically connected to the explosive-type rupture bolt 72 and the detonation timer 18.

67 is a lead wire for transmitting a firing command signal.
This device is set on the launch pad using the slipper 61, and after setting the firing angle and the elapsed time of the discharge timer 75 according to the desired firing range, the firing command signal is sent via the lead wire 67. Release timer 75
When the rocket motor 55 is started, the rocket motor 55 is ignited and the device is launched. Then, when the elapsed time elapses, the release timer 75 sends a signal, and in response to this signal, the detonation timer 18 starts, and at the same time, the explosive-type destruction bolt 72 breaks and the rear cover 71
The contract was released and the pilot parachute 73
is exposed. When the pilot parachute finally opens, the parachute 15 is pulled out and released to open the parachute. Here, when the parachute 15 is exposed to air resistance and its hanging cord expands, the last explosive block 11a is pushed into the container 5 along with the air resistance plate 17.
The explosive blocks are released one after another as the rope 13 is stretched and the next one is pulled out, and finally the detonation timer 18 is pulled out from the housing 54. Then, each explosive block is suspended from the stretched rope 13 with the easily destructible part 20 facing down due to the moderate air resistance force exerted by the air resistance plate 17, and is aligned as shown in FIG. It lands on and unfolds in a straight line. Next, a detonation signal is sent from the detonation timer 18 to detonate each explosive block simultaneously.

FIGS. 5 and 6 mainly illustrate the minefield disposal rocket device for deploying the explosive device of the FIG. 2 embodiment.

In the figure, 101 is a container, and this container is divided into four segments 101a in the longitudinal direction.
101d to 101d are releasably connected as described below, and are combined to form a basket shape. 102
is the front joining means of said segment, and 10
3 is the front of the container, 104 is the segment 101
Explosive-type breaking bolts a to 101d are respectively connected to the front head 103, and leaf springs 105 and 106 are for separating the segments. A leaf spring 106 is similarly fixed to segment 101d and urges segments 101a and 101c outward.

109 is a segment rear joining means,
110 is a hinge arm with four arms protruding radially; 11 is a hinge pin 11 on each arm;
The rear end of each segment 101a to 101d is connected to the hinge blade 112 by a bolt 113.

It should be noted that, like the front coupling means 102, this rear coupling means can also be configured to be releasable using an explosive-type breaking bolt or the like.

115 is a release timer, and 116 is a removable terminal fitting, which is connected to the detonation timer 38 using a lead wire 114. 1
17 is a container 10 with four separation parachutes
1, and their hanging cords 118 are fastened to hooks 119 fixed to the front outer circumferences of the segments 101a to 101d, respectively.

Container 1 combined into a basket shape as described above
01, the explosive block 31 is held in the container using a recessed part 120 formed in an annular shape as a whole so that it cannot move back and forth, and the rope 3
3. It is stored together with the parachute 35, detonation timer 38, etc.

121 is a rocket motor fixed to each segment, and 123 is a tail attached to each rocket motor.

This device uses a slipper at the side edge of a suitable segment, which is engaged with a launch pad, set, and fired by the same procedure as that in FIG. When the elapsed time set in the release timer 115 has elapsed, the detonation timer 38 is activated in response to a signal from the timer 115, and the gunpowder-type destruction bolt 104 is broken to release the connection between the front segments. Then, due to the biasing force of the leaf springs 105 and 106, each segment 101a to 101d is pressed against the hinge pin 11.
2 in the center, and separate parachute 11.
7 is released and opens. Here, each segment receives rotational force from the air resistance of the separating parachute to its hook 119, so that each segment further expands, reverses, and rapidly decelerates, releasing the entire explosive device. Since the forehead 103 flies with high inertia together with the release timer 115, the terminal fitting 116 is pulled out.

In addition, when the rear coupling means 109 is configured to be releasable as described above, each segment is divided into pieces to release the explosive device.

While the explosive device released in this way gradually flies due to inertia, each parachute 35 opens, and if the rearmost parachute 35a is made larger as described above, this will perform a braking action. In addition, if the front parachute 35b etc. are made smaller, the explosive blocks connected to them perform a traction action due to their small deceleration, so in either case, the rope 33 is expanded and the blocks are aligned in series. In this state, as shown in Figure 2, it slowly descends, lands softly, and deploys. Thereafter, each explosive block is detonated simultaneously in response to a signal from the detonation timer 38, as in the case of FIG.

In the embodiment, each explosive block is aligned by changing the capacity of the parachute, but the foremost explosive block 31b is connected to the front head 103 via a rope and pulled by the inertia of this front head. It is also possible to do so.

As explained above, in this invention, since the explosives are concentrated into explosive blocks, the power of each explosive block becomes great, and such explosive blocks can be deployed at appropriate intervals.
When these are detonated simultaneously, each explosive block cooperates to powerfully excite the minefield and dispose of it effectively.

Furthermore, in a case where an easily destructible part is formed in the explosive case and an air resistance element is connected to the opposite side, the easily destructible part lands facing the minefield and is blown up. Detonation waves can be applied extremely effectively against air resistance elements, and those that use parachutes as air resistance elements, especially those that have most or all of them as parachutes, have less impact when they land even when released in the sky. This prevents the mine from being detonated irregularly or the explosive block being detonated intentionally, so this is suitable when you want to increase the firing angle and extend the firing range.

The present invention also provides that after the explosive device has been released from the container, the explosive device is no longer connected to the container, so that the explosive device is not subjected to harmful external forces such as impact forces, and therefore each explosive block is This has the advantage that the firing angle can be arbitrarily selected since the containers can be aligned as intended, and the landing posture of the container side is not a concern, and therefore there is a large degree of freedom in setting the firing range.
