Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus and method for destroying an object to be destroyed using impact energy generated by electric discharge.

[0002]

2. Description of the Related Art Conventionally, there are the following destruction devices for destroying an object to be destroyed such as a concrete structure or a bedrock by using impact energy by electric discharge.

That is, a thin metal wire is attached across the tip portions of a pair of electrodes, and is used as a destructive substance (for which water or a fluidized substance is used) for transmitting generated pressure, which is filled in a mounting hole formed in an object to be destructed. A metal thin wire attached to an electrode is dipped and a capacitor is connected to the other end of the electrode.

In this destruction apparatus, the electric energy charged and accumulated in the capacitor is supplied to the thin metal wire in a short time to rapidly melt and evaporate the thin metal wire and vaporize the destructive substance. To destroy the object to be destroyed.

[0005]

In the above-described destruction apparatus, when the mounting hole is formed from above the object to be destroyed, the mounting hole can be filled with the substance for destruction.
A position suitable for breaking the object to be destroyed is, for example, a side portion thereof, and when it is necessary to form a mounting hole in a horizontal direction, or a position suitable for breaking the object to be destroyed is a lower portion thereof, In the case where it is necessary to form the mounting hole in the elevation direction, the mounting hole cannot be filled with the substance for destruction, and it becomes difficult to destroy the object to be destroyed.

Therefore, an object of the present invention is to provide an apparatus and method for destroying an object to be destroyed which can solve the above problems.

[0007]

Means for solving the problems of the present invention is to provide a destruction container to be mounted in a mounting hole formed in an object to be destroyed, fill the destruction container with a substance for destruction, and destroy the destruction. Each metal thin wire connecting one end side of multiple sets of electrodes to the working substance is soaked as to be displaced in the depth direction of the mounting hole, so that the breaking substance spills out from the mounting hole. It is possible to deal with any direction of the mounting hole formed in the object to be destroyed, and the object can be destroyed from the desired direction.

Further, the inside of the destruction container is partitioned by a partition plate for partitioning between the metal thin wires, and a capacitor for charging and accumulating electric energy supplied to each metal thin wire is connected to the other end of each pair of electrodes. The method of destroying the object to be destroyed in this destruction apparatus is to supply the electric energy charged and accumulated in each capacitor in order from the metal thin wire deep in the mounting hole. Is supplied to melt and evaporate it, and the destructive substance is rapidly vaporized to generate an impact pressure, which acts on the destructible object to destroy or weaken it. Since the inside of the destruction container is divided by a partition plate that separates each metal thin wire, when destroying the object to be destroyed, this partition plate melts and evaporates the predetermined metal thin wires for destruction. Quality is prevented from impact pressure generated when rapidly vaporized is transmitted to other thin metal wire side,
It is possible to prevent other thin metal wires that have not yet supplied electrical energy from cutting, and by successively supplying electrical energy to the thin metal wires, a continuous impact pressure can be reliably obtained.
The object to be destroyed can be surely destroyed.

5b.

Next, a description will be given of a destruction method of destroying the object to be destroyed H1 by using the destruction device 1 having the above structure.
The destruction container 2 is filled with the destruction substance 3 and the sealing plug 2a
, The metal rods 8a, 8b attached to the electrode rods 4a, 4b are inserted, the destruction container 2 is covered with a cap 2a, and the metal thin wires 8a, 8b are immersed in the substance 3 for destruction to destroy the destruction container 2 Each terminal 5 is mounted in the mounting hole 20a formed in H1.
The energy supply device 9 is connected to a and 5b, and the charge switch 14 of the charge control circuit 11 is turned on to turn on each capacitor 1
Electric energy is stored in 3a and 13b.

Next, when the control device 16 is driven, the discharge switch 12a is provided from the control device 16 to the first drive circuit 17.
A control signal is output to turn on the discharge switch 12
When a is turned on, electric energy is first supplied from the condenser 13a to the thin metal wire 8a at the deep position of the mounting hole 20a, and the thin metal wire 8a is melted and evaporated. Then, after a short time has passed, the control device 16 drives the second drive circuit 18
Then, a control signal is output to turn on the discharge switch 12b, the discharge switch 12b is turned on, electric energy is supplied from the condenser 13b to the thin metal wire 8b at the shallow position of the mounting hole 20a, and the thin metal wire 8b is melted and evaporated. .

As the thin metal wires 8a and 8b are melted and evaporated, the destructive substance 3 is rapidly vaporized to generate an impact pressure, which acts on the object to be destroyed H1 and destroys the object to be destroyed H1. Or it can be weakened.

By the way, in order to obtain a large impact pressure,
Although it is sufficient to increase the voltage value of the power supply device 10, in consideration of technical constraints, energy efficiency, and destruction efficiency, the electric energy stored in the energy storage circuit is divided rather than the one-point discharge using one thin metal wire. The multi-point discharge used later is superior. Therefore, as described above, the two thin metal wires 8
a and 8b are connected to the electrode rods 4a and 4b of each set so as to destroy the object to be destroyed H1.

For example, the two-point discharge of 1000 V-50 μF can improve the impact force against the object to be destroyed, as compared with the one-point discharge of 1000 V-100 μF. Although not shown, when the side portion of the object to be destroyed H1 is to be destroyed, the mounting hole 20a is drilled in the horizontal direction, the destruction container 2 is laterally mounted to the mounting hole 20a, and the destruction is performed in the same manner as described above.

In this case, even if the mounting hole 20a is formed in the object H1 in the horizontal direction, the destruction container 3 is already filled with the destruction substance 3, so that the destruction substance 3 is inserted from the mounting hole 20a. No spillage, so
The mounting hole 20a formed in the object to be destroyed H1 can be oriented in any direction, and the object to be destroyed H1 can be destroyed from a desired direction.

By the way, in the destruction container 2, each thin metal wire 8
Since it is partitioned by the partition plate 19 for partitioning between a and 8b, even when one of the metal thin wires 8a at a deep position is melted and evaporated and the destruction material 3 is rapidly vaporized, the impact at that time is It is possible to prevent the other thin metal wire 8b in the shallow position from being reached, and therefore, the other thin metal wire 8b is not cut, and the fine wire 8b that has not yet supplied the electric energy is cut off so that the misfire does not occur. It is possible to avoid the phenomenon of becoming.

As described above, according to the first embodiment of the present invention, the thin metal wires 8a and 8b are mounted on the destruction container 2 filled with the destruction material 3, so that the destruction target H1 is mounted on the destruction target H1. The breaking substance 3 does not spill out of the mounting hole 20a regardless of the direction of the hole 20a, so that the object to be broken H1 can be broken from a desired direction, and a plurality of sets of electrode rods 4a can be formed. Since the metal thin wires 8a and 8b connecting the tip portions of the metal wires 4a and 4b are displaced in the depth direction of the mounting hole 20a and immersed in the destruction material 3, one thin metal wire can be used even with a small amount of electric energy. A large impact pressure can be obtained as compared with the one-point discharge used, and it is particularly useful when the object to be destroyed H1 has a large thickness (when the mounting hole 20a is deep). Further, in the destruction container, each thin metal wire 8a, 8b
Since the partition plate 19 is used for partitioning the space, even when one of the thin metal wires 8a melts and evaporates and the destructive substance 3 suddenly vaporizes, the impact at that time does not reach the other thin metal wire 8b. Therefore, it is possible to prevent the other thin metal wire 8b, which has not yet been supplied with electric energy, from being cut, and to supply the other thin metal wire 8b with electric energy to ensure continuous impact pressure. Obtain and destroy the object H
1 can be destroyed surely.

Next, a second embodiment of the present invention will be described with reference to FIG. 2. This is a single electrode wire in which the core wire 31a is covered with the insulating coating 30 and inserted into the sealing plug 36a. A common electrode line 31 is provided, and a plurality of (four in the figure) electrode lines 32 to 35 are provided along the common electrode line 31 with a sealing plug 36 a.
The core wire 31a of the common electrode wire 31 and the core wires 32a to 35a of the electrode wires 32 to 35 used as the thin metal wires.
Are immersed in the destruction substance 37, which is displaced in the depth direction of the destruction container 36 and attached by welding or the like and filled in the destruction container 36. Inside the destruction container 36, the core wires 3 of the electrode wires 32 to 35 are
It is partitioned by a partition plate 38 for partitioning between 2a and 35a.

Then, the common electrode line 31 and the electrode line 32
Is a terminal 32b.
To 35b, and the core wires 3 are attached to the terminals 32b to 35b.
An energy supply device (not shown) for supplying electric energy to 2a to 35a is connected.

Since the destruction apparatus according to the second embodiment is provided with two metal thin wires in addition to the destruction apparatus according to the first embodiment, the energy supply apparatus according to the second embodiment has the energy shown in the first embodiment. A charging device, a capacitor, a discharge switch, and two drive circuits are added to the supply device, and the control device that controls the drive of the drive circuit drives the four drive circuits with a slight time difference and each discharge It has the function of sequentially turning on the switches.

Since the other structure is the same as that of the first embodiment, the same reference numerals are given and the description thereof is omitted. Next, the destruction method in the second embodiment will be described. The destruction container 36 is mounted in the mounting hole 20a formed in the object to be destroyed H1 and is located at a deep position with respect to the mounting hole 20a by the drive control of the drive circuit by the controller. Electrode wire 3 at a shallow position from electrode wire 32
5, the discharge switches are sequentially turned on so that electric energy is supplied from the capacitors.

Then, as the core wires 32a to 35a are sequentially melted and evaporated, the destructive substance 37 is rapidly vaporized to generate an impact pressure, which acts on the destructible object H1 to destroy the destructible object H1. It can also be weakened.

Also in this case, as in the first embodiment, the inside of the destruction container 36 is partitioned by the partition plate 38 for partitioning the core wires 32a to 35a, so that the core wire 32a at a deep position is formed.
Even when the destructive substance 37 is rapidly vaporized by melting and evaporating, the impact at that time can be prevented from reaching the other core wires 33a to 35a, and therefore, the core wire to which electric energy has not been supplied yet. It is possible to avoid a phenomenon in which 33a to 35a are cut off and the other core wires 33a to
By successively supplying electric energy to 35a, it is possible to obtain continuous impact pressure and reliably destroy or weaken the object to be destroyed H1.

[0027]

As is apparent from the above description, in the present invention, the thin metal wire is inserted into the destruction container to be mounted in the mounting hole formed in the object to be destroyed. The destructive substance does not spill out of the mounting hole regardless of the direction of the holes, so that the object to be destroyed can be destroyed from the desired direction, and the ends of the multiple sets of electrodes can be Since each connected thin metal wire is displaced in the depth direction of the mounting hole and immersed in the destruction material filled in the destruction container, the destruction object is surely destroyed even if the destruction object to be destroyed is thick. Since it can be weakened and weakened, and the inside of the destruction container is partitioned by a partition plate that partitions between the metal thin wires, even when the predetermined metal thin wires are melted and evaporated and the destruction material is rapidly vaporized. , The impact at that time is still electric energy Can be prevented from reaching the thin metal wire that has not been supplied, and this can be prevented from being cut. Therefore, by successively supplying electric energy to other thin metal wires, a continuous impact pressure can be obtained, It is possible to reliably destroy or weaken a destroyed object.
