- the present invention melts and vaporizes electric energy by supplying it to a molten vaporized substance (for example, a thin metal wire) in a short period of time, and explodes nitromethane by the phenomenon of the process accompanying the molten vaporization, thereby forming a concrete structure.
- a molten vaporized substance for example, a thin metal wire
- the present invention relates to a destruction device and a destruction method for destroying an object to be destroyed such as rock or rock. Background art
- destruction devices for destroying objects to be destroyed such as concrete and bedrock include dynamite and a detonator as a means of exploding the dynamite.
- dynamite uses an insensitive explosive that does not easily explode when subjected to a slight impact force or even when ignited. For this reason, the primer is charged with explosive that explodes relatively easily, and the explosive charged in the primer is exploded by fire or electric spark, and the explosion explodes the explosive used for dynamite. Like that. However, as described above, since the primer is filled with explosives that explode relatively easily, leakage current, surge, lightning, etc. of equipment around the controlled place occurs, and these currents are applied to the primer. If supplied, there is a risk that the primer will explode.
- an object of the present invention is to provide a destruction device and a destruction method that can solve the above-mentioned problems. . Disclosure of the invention
- a nitromethane is filled in a destruction container mounted on an object to be destroyed, and a predetermined amount of electric energy is supplied to the nitromethane in a short time, thereby exposing a molten vaporized material that rapidly melts and vaporizes,
- An electric energy supply circuit having a capacitor for storing a predetermined amount of electric energy supplied to the molten vaporized material is provided, and when the predetermined amount of electric energy is supplied, the molten vaporized material is melted and vaporized.
- This is a destruction device that explodes the above-mentioned methane in the process of breaking down, and uses the explosive power to destroy objects to be destroyed.
- the present invention when a predetermined amount of electric energy is stored in the condenser and the electric energy is supplied from the electric energy supply circuit to the molten vaporized material, the molten vaporized material is rapidly melted and vaporized, and this is melted and vaporized. Nitromethane explodes in the process of becoming a gas, and the explosive force destroys the object to be destroyed. Even if there is a leakage current from peripheral equipment, nitromethane does not explode unless electric energy enough to melt and vaporize the molten vaporized substance is supplied, so safety in handling the destruction device is improved. Further, the present invention is a destruction device using nitromethane.
- nitromethane does not explode unless electric energy enough to melt and vaporize the molten vaporized material is supplied, so that safety in handling the destruction device is improved.
- the present invention exposes a molten vaporized material that rapidly melts and vaporizes when a predetermined amount of electric energy is supplied in a short time to nitromethane filled in a destruction vessel. Electric energy enough to melt and vaporize is supplied from the condenser, and the molten vaporized material melts and vaporizes. It is a destruction method that explodes nitromethane by the process phenomenon and uses the explosive power to destroy the object to be destroyed.
- FIG. 1 is a cross-sectional view showing the entire configuration of a destruction device according to an embodiment of the present invention and a state in which a destruction container is mounted in a mounting hole of an object to be destroyed
- FIG. It is an expanded sectional view showing the state where the destruction container was attached to the attachment hole of the thing.
- the breaking device 1 rapidly melts and vaporizes a thin metal wire 2 made of copper (Cu) having a diameter of 0.3 mm as an example of a molten vaporized material.
- the accompanying phenomena namely, discharge, sparks, heat generation, and explosion of nitromethane 3 by the impact force generated by vaporization and expansion,
- the nitromethane 3 is attached to a mounting hole 5 formed in the destroyed object 4.
- the destruction vessel 6 is filled, the open side of the destruction vessel 6 is sealed with a lid member 7, a pair of electrodes 8 is inserted through the lid member 7, and the tips of the electrodes 8 are connected to nitromethane 3. They are connected by the exposed thin metal wires 2.
- a nonmetal such as wood, paper, or synthetic resin, or a metal such as aluminum or iron is used.
- an electric energy supply circuit 10 connected to the thin metal wire 2 is provided, and the electric energy supply circuit 10 supplies a predetermined amount of electric energy to the thin metal wire 2 to melt and vaporize the thin metal wire 2. Things.
- the electric energy supply circuit 10 includes a power supply device 11 connected between the terminals 8a of the electrodes 8 and a capacitor 14 connected in parallel between the power supply device 11 and both terminals 8a.
- a charge control circuit 12 connected between the power supply device 11 and one terminal 8a for controlling a capacitor 14 to store a predetermined amount of electric energy; It comprises a discharge switch 13 connected between the circuit 12 and one terminal 8a.
- the distal ends of both electrodes 8 are connected to each other with a thin metal wire 2, each electrode 8 is passed through the lid member 7, the destruction container 6 is filled with nitromethane 3, and the lid member 7 is disposed in the destruction container. Attach it to 6 to seal nitromethane 3 and connect the electric energy supply circuit 10 to the terminal 8 a of both electrodes 8 to make it. Shape 4 Then, a predetermined electric energy required for the metal wire 2 to melt and evaporate is accumulated in the capacitor 14 and the discharge switch 13 is turned on.
- the electric energy is supplied to the thin metal wire 2 in a short time and rapidly melts and vaporizes, and the above-described phenomenon accompanying the process of melting and vaporizing the fine metal wire 2 explodes nitromethane 3 to melt and vaporize the fine metal wire 2.
- the explosive force of nitromethane 3 is added to the impact force generated at that time, and the wreck 4 is reliably destroyed or weakened.
- the destroying vessel 6 is filled with nitromethane 3 and the metal wire 2 connected between the electrodes 8 is used in place of the primer. Energy is supplied and melted and vaporized. Therefore, even if leakage current from peripheral equipment is supplied to the fine metal wire 2, electric energy only melts and vaporizes the fine metal wire 2. Since the nitromethane 3 does not explode unless one is supplied, the destruction device 1 can be handled safely.
- the impact force F required for detonating nitromethane 3 is about 70 [ton ⁇ f / cm 2 ].
