Description

Detailed Description of the Invention (Industrial Field of Application) The present invention relates to a detonator for a mine field disposal device, and more specifically, to a connected device in which a plurality of explosive blocks, each of which is equipped with a detonator, are connected in series by a connecting cable. After being carried into the sky by a flying object, the connected body was braked from the rear, and was deployed in a string of beads and lowered onto the minefield, where the explosive block was detonated to detonate the mine. The present invention relates to the detonator in the device.

(Prior art) Conventionally, such a minefield disposal device has been developed, for example, by
This is disclosed in Japanese Patent No. 9-74500, and will be briefly explained using FIG.

The figure shows the state when the explosive blocks are deployed in a string as mentioned above. 1 is a block with multiple explosive blocks (hereinafter referred to as blocks) loaded with explosives in a sealed short cylindrical can body. , each block is equipped with a detonator 2. Reference numeral 3 denotes a connecting cable that is connected to seven links 4, 4 fixed at the front and rear of the can body of the block to sequentially connect the blocks 1 in series;
A parachute 6 is connected to the rear of the connected block body 5 by means of a hanging cord 7, and a timer 8 is connected to the front of the connected body 5 by a connecting rope 9. Reference numeral 10 denotes a detonation signal transmission cable arranged loosely along the connecting cables 3 and 9, and transmits a detonation signal from the timer 8, which will be described later, to the detonation device 2 of each block 1.

On the other hand, 15 is a rocket flying object, 16 is a fuselage, 17 is four rocket motors equipped on this fuselage, and 18 is a connecting cable connected from the head 19 of the flying object through the fuselage 16 to the timer fU 8. It is. The appearance of the inclined device on the ground is as follows. That is, with each connecting rope 18, 9.3 and cable 10 compactly tied together, the timer 8 is removably installed in the head 19, and each block 1 is attached to the trunk shell 1.
6, the parachute 6 is folded and stored in the rear part of the fuselage, and the rear cover 20 has a gunpowder-type destruction bolt 21.
It is fastened to the rear end of the fuselage.

In the above configuration, an operating command is sent to the rocket motor 11 to launch the flying object 15 toward the minefield, and when the flying object 15 flies to the sky above the destination, the bolt 21 is broken and the rear cover 20 is removed.

At this point, the parachute 6 is released and opened to apply aerodynamic braking to the rear of the block connection body 5, so that each block 1
The timer 8 is then pulled out of the trunk shell 16, and the connecting cables 3,
9.18 expands and these blocks develop into a string of beads. In this state, it descends onto the minefield and lands.

On the other hand, the timer 8 is set with the time in seconds until the completion of landing based on the above-mentioned firing time, and when this time has elapsed, a detonation signal such as an electric signal or a detonation wave signal is transmitted.

The cable 10 is a flexible wire when the detonation signal is an electric signal, and a detonation wire when the detonation signal is a detonation wave signal, and the cable 10 simultaneously transmits the detonation signal to each detonation device 2. Then, block 1 that landed will explode in unison.

(Problem) Generally, a detonator is equipped with a safety device that restricts it to an inoperative state, and the inertia of the firing impact is used to release the restriction.

By the way, in devices equipped with a common timer for detonating multiple blocks at the same time, such as the aforementioned mine field processing equipment, this timer may be able to emit an untimely signal in the event of a launch impact, etc. If something were to emit, it could cause a sudden explosion near the launch site, leading to a serious accident.

Therefore, an object of the present invention is to ensure that the restraint is not released until after the minefield disposal device has been transported sufficiently far.

(Means of the Invention) To solve the above problems, the detonator of the present invention includes a removable lock bin that restrains the detonator in an inoperable state;
And, it has a pull rope connected to this lock pin and a connecting rope or another block, and the length of this pull rope is set shorter than the length of the connecting rope that exists between the above connection parts. .

(Function) According to the above means, the length of the pull rope connected to the lock pin is set as described above, so that in the process of expanding the block, the pull rope is expanded before the connecting rope finishes being expanded. The lock bin will be pulled out. Therefore, the inoperative state of the detonator is released and the detonator is ready to detonate for the first time.

,(Example) 1 to 3 show an embodiment of the present invention.

In the detonator 30 shown in FIGS. 1 and 2, 31
32 is a cylindrical casing, 32 is a flange formed at one end of this casing (upper end in the drawing), 33 is a body fitted into the casing 31, 34 is a cover fastened with bolts 35 to the flange 32, and the body 33 is A flange-like protrusion 36 formed on the upper end of the 7 flange 32 and the cover 3
4 and are clamped and fixed.

37 is a housing formed by punching out the body 33 with a predetermined width in the diametrical direction, 38 is a fan-shaped rotor inserted into this housing, and 39 is a pin that rotatably supports this rotor at a fan-shaped latch. , the pin 39 is located on the central axis of the body 33 and is arranged at right angles thereto. 40 is a bottomed chamber formed in the radial direction of the rotor 38; 41 is a flame path extending from near the bottom of the chamber to both sides of the rotor 38; 42 is a relay charge loaded in the chamber 40;
3 is a screw coil spring that urges the rotor 38 counterclockwise in the drawing, and 44 is a stopper surface formed on the housing 37, so that the rotor 38 is in the position shown by the solid line in the drawing, that is, the chamber 40 is in the position of the body 33. 9 from radial orientation
When rotated by 0° (indicated by two-dot chain line), one end surface 3 of the rotor
8a collides with the stopper surface 44 and stops. This stop [
7, 45 is a pair of electric detonators arranged opposite to the flame duct 41, and in this state, 46 is a through hole formed in the lower end of the body 33 so as to face the chamber 40;
47 is a transfer charge loaded into this hole, 48 is a camp screwed onto the lower end of the body 33, and 49 is a point explosive loaded into this camp.

Reference numeral 60 denotes a locking pin, which is pushed vertically into the body 33 and whose lower end is placed close to the one end surface 38a of the rotor 38 in the position shown by the solid line, and which is screwed onto the body 33 and has a holder 61 which slides onto the body. It is supported by being loosely inserted into a movably fitted receiving pin 62, and this receiving pin is biased toward the rotor 38 by a tension spring 63. Therefore, the rotor 38 energized by the spring 43 is locked by the locking pin 60, and its rotation is restricted.

In this state, 65 is a lock pin that passes through the body 33 from the 7 flange 32 of the casing 31 and is inserted into the locking pin 60, 66 is a pull cable connected to the end of this lock pin, and 6T
is a compression spring that urges the lock pin 60 upward.

10.10 is the cable (flexible wire), 68 is a ground for pulling in the cable, and the cable 10.10
are drawn into the wiring chamber 69 and connected to each other, and an electric wire 70 is branched from this joint to the electric detonator 45.

FIG. 3 shows an example of the connection mode of the pull rope 66 in the above-mentioned state on the ground, where 71 is the connection portion of the lock pin 65-\ in the block 1 (Ia), and 72 is the connection at the other end of the pull rope. At this point, the connecting portion 72 is on the connecting rope 3 and is located near the adjacent block 1 (lb), and between these connecting portions, the connecting rope 3 is gathered together in a meandering manner and has a sufficient length. On the other hand, the lead rope 66 has a shorter length than this length so that it can be spanned with less slack. However, it is clear that this length condition can be satisfied even if the other end of the pull cable is connected to an appropriate position of the adjacent block 1b, for example, to the hook 4, or even if it is further connected to an adjacent block.

The embodiment is as described above, and since the rotor 38 is normally restrained in the attitude shown by the solid line, even if the detonator 45 accidentally ignites, the flame will only collide with the side surface of the rotor and detonate. The device 30 as a whole is maintained in an inactive state. After the flying object 15 is launched, in the process of deploying it following the above-mentioned process, the tow rope 66 is expanded and the lock pin 6 is expanded.
5 is pulled out, the locking pin 60 is pushed up by the spring 6T, and the restraint of the rotor 38 is released by this tL, causing the rotor to rotate 90 degrees. Therefore, the electric detonator is the flame path 4
1, the chambers 40 face each of the through holes 46, and in this state the minefield descends and lands on the minefield.

Here, when a detonation signal (electrical signal) is issued from the timer 8, the electric detonator 45 ignites and burns the relay charge 42 and then the flame transfer charge 4T to ignite the ignition charge 49 and detonate the block 1. do.

(Effects) ′ As explained above, the present invention makes it possible to detonate the block when it is transported to the vicinity of the minefield.
The safety of personnel, equipment, etc. near the projectile launch point is ensured, and the inoperable state can be released by the simple action of pulling out the lock bin, and this pulling out uses the deployment movement of the block, which is a heavy object. Therefore, a strong pulling force can be obtained, and since there are very few factors inhibiting these actions in the sky, the above-mentioned release can be performed reliably.
