2. Description of the Related Art Conventionally, when a fire occurs in a forest, a forest, a high-rise building, an undeveloped land, or the like where a fire engine cannot extinguish a fire,
Fire extinguisher was sprayed from the air to the fire site by helicopter or small airplane. However, in this case, the sprayed fire extinguishing agent is diffused over a wide area by an air current generated by a propeller or a fan of a helicopter or a small airplane or an air current in the sky. Therefore, in order to spray a sufficient amount of fire extinguishing agent on the fire site to extinguish a fire, a huge amount of fire extinguishing agent must be sprayed from the air. Therefore, there was a problem that fire extinguishing could not be carried out efficiently in a short time and economically.

[0003] Therefore, recently, a fire extinguisher spraying apparatus equipped with a fire extinguishing agent and explosives has been proposed. The fire extinguisher can be sprayed by dropping the fire extinguisher spray device from a helicopter or a small airplane toward a target fire site and exploding the loaded explosives in the air.

[0004] However, this fire extinguisher spraying apparatus has the following problems. That is, the explosives to be loaded are
It is subject to crackdown by the Explosives Control Law. For this reason, the explosives must be manufactured in an explosives manufacturing plant and then stored in an explosive storage that conforms to legal standards. In order to construct a gunpowder, it is necessary to secure a sufficient security distance, and it is often difficult to secure it in narrow Japan. Therefore, in many cases, it is necessary to use an already constructed explosive storage, but the number of existing explosive storages is limited, and there is no explosive storage to store even if a large amount of fire extinguisher spraying equipment is manufactured. There's a problem.

Since it is used in an emergency, it is extremely difficult to obtain a permit or the like in advance. In this case, even if a fire extinguisher spraying apparatus is manufactured, it cannot be used effectively. Further, if the above-mentioned license is obtained after a fire has occurred, there is a problem that the damage of the fire cannot be minimized because it is not always possible to obtain the license immediately as always in a license system. On the other hand, even if permission or the like can be obtained, the fire extinguisher spraying device must be taken to the explosive storage, and rapid fire fighting cannot be performed.

Further, the above-mentioned fire extinguisher spraying apparatus is equipped with explosives capable of generating a strong explosive force required for spraying the fire extinguisher, but the explosives explode due to erroneous operation or the like. It may be very dangerous. Therefore, only those skilled in handling explosives can use the fire extinguisher spraying apparatus. Therefore, development of a fire extinguisher spraying apparatus which does not have the above-described problems and is easy to transport and handle is desired.

The operation of the fire-extinguishing bomb of this embodiment will be described below with reference to the drawings. FIG. 2 is a schematic cross-sectional explanatory view showing an operation state of the fire-extinguishing bomb shown in FIG.

First, the fire extinguisher 1 is mounted on an airplane or a helicopter, and heads for a fire site such as a forest, a forest, or a high-rise building. The fire extinguisher bomb 1 is dropped from the sky near the fire site.
When the fire extinguisher bomb 1 falls to an appropriate height, the drawer 16 is operated by remote control. This opens the parachute of the parachute device. Then, the fire extinguisher 1 drops toward the fire site at a speed much lower than the initial drop speed due to the air resistance received by the parachute.

At this time, the pulling string 15 is pulled by a pulling force acting in the direction in which the fire-extinguishing bomb 1 falls in a direction opposite to the direction in which the fire-extinguishing bullet 1 falls. A portion of the drawstring 15 connecting the drawn body 16 and the partition body 8 is in a tensioned state. The partition 8 moves in the cylindrical body 6 in the direction in which the pulling force acts by the pulling force. The partition body 8 in the drawing string 15
The portion connecting the and the bottom body 7 is in a tension state. The bottom body 7 moves in the cylindrical body 6 in the direction in which the pulling force acts by the pulling force.

When the bottom 7 is rapidly separated from the bottom receiving portion 6a in the cylinder 6, the pressure in the igniter chamber 9c is rapidly reduced. The explosive first precursor 10a and the explosive precursor 10b rapidly fall into the ignition device chamber 9c from the gap with the surface and flow into the ignition device chamber 9c. By this inflow, the first explosive precursor 10a and the explosive precursor 10b are mixed, and an explosive (explosives) 17 is prepared.

Further, due to the pulling force, the bottom body 7 is
When the inside of the cylindrical body 6 is moved in the direction in which the pulling force acts, the friction line 14c connected to the end of the pull cord 15 is also rapidly pulled out, and the tip end of the friction line 14c rapidly moves through the ignition charge 14b. pass. The friction between the rubbing agent 14d applied to the tip of the friction line 14c and the igniting agent 14b causes
b ignites.

By the ignition, the igniting agent 12b is instantaneously burned. By the burning of the ignition charge 12b, the delay medicine 13b burns. The burning time of the postponed medicine 13b is adjusted to the time required for the fire extinguisher 1 to reach an appropriate height for spraying the fire extinguishing agent 3. When the burning surface of the delayed charge 13b reaches the other end of the container 13a from the opening on the side of the igniting charge loading section 12, the prepared explosive is ignited and the explosive burns explosively.

The cylinder 6 ruptures due to the burning of the explosive.
Further, along with this, the container 2 bursts and the fire extinguishing agent 3
Scatters. As a result, the fire extinguisher 3 is sprayed toward the fire site. Most of the fire extinguishing agent 3 is sprayed to the fire site without any loss.

According to the fire extinguisher 1 described above, the following technical effects can be obtained. That is, since the fire extinguisher 1 contains only the explosive first precursor 10a and the explosive precursor 10b which are not the explosives themselves, the fire extinguisher 1 is not an object of the Explosives Control Law. This fire extinguisher 1 is easy to transport and handle and has no danger of explosion. In addition, no special equipment such as an explosive storage is required for preservation, and it can be handled without obtaining prior permission from related government agencies. Further, the fire extinguisher 1 can spray the fire extinguisher 3 efficiently at a target location without being affected by airflow or the like in the sky.

Among these, a cylindrical shape, a prismatic shape, a cubic shape, a rectangular parallelepiped shape, an inverted truncated cone shape, and the like are preferable because they are easy to transport and store.

The container 2 may be used as a container exclusively for the fire extinguisher 3. In this case, the explosive device 5
The fire extinguishing agent 3 is fixed in parallel or in parallel with the container 2 filled therein.

The material of the container 2 is such that it is not easily broken during handling such as transportation and storage, and the release medicine 1
There is no particular limitation as long as it is a material that can be easily ruptured at the time of the explosion of 7, and it can be appropriately selected according to the purpose. Can be mentioned. Among them, paper such as cardboard, plastic and cloth are preferable. The paper and fabric are suitable for powder fire extinguishing media, and the plastics are suitable for powder and liquid fire extinguishing media.

In this case, the mixing of the first explosive precursor 10a and the first explosive precursor 10b is performed efficiently. In addition, instead of providing the impeller 7b, a spiral groove may be formed on the peripheral side surface of the disk member 7a. In this case, as the explosive first precursor 10a and the explosive precursor 10b fall while rotating along the groove with the movement of the bottom body 7, these can be efficiently mixed. .

The bottom body 7 shown in FIG. 5 is an inverted conical member. The use of the bottom body 7 and the bottom body receiving portion 6a having a triangular cross section shown in FIG. 5 is advantageous in the following points.

For example, a cylinder having a diameter smaller than the inner diameter of the cylinder 6 may be used instead of the partition plate 8a. The partition body 8 has a shape of the cylindrical body 6 and the bottom body 7,
The shape, material, and the like can be appropriately selected according to the size and the like. Examples of the material of the partition 8 include the same material as the material of the container 2. Among them, paper such as cardboard, plastic and the like are preferable.
