DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, a destructive device according to a first embodiment of the present invention will be described based on a plan view of FIG. 1 and a cross-sectional view of FIG.
[0008]
The destructive device 1 according to the first embodiment of the present invention is suitable for destroying an object G embedded in sand 2, and includes a destructive probe 3 embedded in sand 2 and a metal thin wire 4 described later. An energy supply circuit (not shown) for supplying a predetermined amount of electric energy is provided. The destruction probe 3 is connected to the destruction container 5 embedded in the sand 2, the thin metal wire (an example of a vaporized substance that is melted and vaporized) 4 inserted into the destruction container 5, and the thin metal wire 4. In addition, a pair of electrodes 6 inserted through the lid member 5a, and a destruction substance (water, oil) filled in the destruction container 5 to transmit the volume expansion force outwardly when the fine metal wire 4 is melted and vaporized. Alternatively, an explosive substance such as nitromethane is used) 7, and the energy supply circuit is connected between the electrodes 6.
[0009]
Moreover, the destruction apparatus 1 which concerns on embodiment of this invention surrounds the destruction container 5 and the to-be-destructed object G, and prevents the movement of the to-be-destructed object G when the metal thin wire 4 is volume-expanded. A metal movement preventing member 8 (upper and lower sides open) is provided. The diameter D1 of the movement preventing member 8 is set based on the size L of the destruction object G and the diameter D2 of the destruction container 5, and when the destruction object G and the destruction container 5 are tangled together, the diameter of the movement prevention member 8 surrounds both. Is formed.
[0010]
A method of destroying the destruction object G using the destruction apparatus 1 will be described. The movement blocking member is formed in the sand 2 so as to tie the destruction probe 3 to the destruction object G by setting the diameter D1 of the movement prevention member 8 from the size L of the destruction object G and the diameter D2 of the destruction container 5. Fill in as if pushing 8 in. Thereby, this destruction container 5 and the to-be-destructed object G will be in the state surrounded by the movement prevention member 8 in the circumferential direction.
[0011]
In this state, when a predetermined amount of electrical energy (for example, 6500 V) is supplied from the energy supply circuit to the fine metal wires 4, the fine metal wires 4 and the destructive substance 7 are rapidly melted and vaporized and expanded. The force is transmitted outward by the destructive material 7 to generate an impact force, and this impact force acts on the object G to be destroyed. At this time, even if the to-be-destructed object G is in the sand 2 and is in an unstable state, the to-be-destructed object G is prevented from moving by the movement-preventing member 8, so that the movement can be suppressed by the generated impact force. Therefore, the to-be-destructed object G is destroyed reliably.
[0012]
Next, a second embodiment of the present invention will be described based on the plan view of FIG. 3 and the sectional view of FIG. The destruction device 1 according to the second embodiment of the present invention is provided with a pair of destruction probes 3 and an energy supply circuit for supplying a predetermined amount of electric energy to the fine metal wires 4 of each destruction probe 3. It is what was done. In addition, each destruction container 5 in the second embodiment of the present invention is welded to both sides of the inner surface of the metal movement prevention member 8 or bonded to both sides of the inner surface of the synthetic resin movement prevention member 8, and each destruction The space between the containers 5 is a holding space for holding the object G to be destroyed.
[0013]
The method of destroying the to-be-destructed object G using the destruction apparatus 1 in 2nd embodiment of this invention is demonstrated. The diameter D1 of the movement preventing member 8 is set from the size L of the destruction target G and the diameter D2 of the destruction container 5, and each destruction container 5 is fixed to both sides of the inner surface of the movement preventing member 8. Subsequently, the movement preventing member 8 is embedded in the sand 2 so that the destruction object G is sandwiched between the respective destruction containers 5, and a predetermined amount of electric energy is supplied from the energy supply circuit in the same manner as in the first embodiment. Supply to the fine metal wire 4.
[0014]
Then, the fine metal wire 4 and the breaking material 7 are rapidly melted and vaporized and expanded, and the expansion force of the fine metal wire 4 is transmitted outward by the breaking material 7 to generate an impact force. This impact force is destroyed. Work on object G from both sides. At this time, even though the destruction object G is in the sand 2 and is in an unstable state, the destruction object G is generated because the movement prevention member 8 is prevented from moving through the both destruction containers 5. Movement is suppressed by the impact force, and a strong impact force is obtained by the destruction probes 3 on both sides of the destruction object G, so that the destruction object G is reliably destroyed.
[0015]
In each of the above embodiments, the example of the object G to be destroyed is embedded in the sand 2. However, the present invention is not limited to this. For example, a buoy floating in the sea or on the sea, an old hull, etc. It can also be applied to destroying the object G to be destroyed. If it is in the sea, the destruction container 5 is formed in a vertically open cylindrical shape, and the seawater (vaporizing substance) that is an electrolytic solution is used as it is instead of the thin metal wire 4, A predetermined amount of electric energy is supplied from the energy supply circuit between the electrodes 6 to cause gap discharge, whereby the seawater in the destruction container 5 is vaporized, and the object G is destroyed by the impact force associated with the vaporization expansion at that time. You can also. Also in this case, since the movement of the destructible object G is blocked by the movement blocking member 8, the movement is suppressed by the generated impact force, and therefore the destructible object G is reliably destroyed.
[0016]
Further, in each of the above embodiments, the metal thin wire 4 is used as an example of a vaporizing substance that is melted and vaporized. However, the present invention is not limited to this, and a metal piece or carbon may be used. The same effects as the embodiment can be obtained.
[0017]
