DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire extinguishing method using a fire extinguisher that can spray a fire extinguisher accurately on a fire site.

[0002]

2. Description of the Related Art Hitherto, there has been proposed a system in which a fire extinguishing munition is simply fired from the ground and hit at a destination to extinguish a fire, for example, Japanese Patent Application Laid-Open Nos. 48-64799 and 49-9.
No. 092 and the like. A fire extinguisher is like a fire extinguisher, and can be quickly extinguished by hitting the fire site.

[0003] JP-A-5-270496 and JP-A-6-14
No. 4381 discloses a prior art in which fire is extinguished by discharging water from a helicopter. In JP-A-5-270496, a water tank or the like is mounted on a helicopter, and water is discharged from a nozzle provided in front. In JP-A-6-144381, the ground and the helicopter are connected by a hose, and water pumped by a ground pump is discharged from a nozzle provided in the helicopter.

[0004] In each of the above prior arts, fire extinguishing in a skyscraper or the like, which is difficult to extinguish from a fire engine by water discharge, and fire extinguishing when a fire engine does not easily approach a fire site when a large-scale disaster occurs. It is possible.

[0005]

In a system in which a fire-extinguishing bomb is simply fired from the ground and hits a destination, the accuracy of hitting is not always good, so that it is not possible to be far away from a fire occurrence site. If the fire is away from a safe distance, it becomes difficult to hit the fire extinguisher at the fire site, and even if a small amount of fire extinguisher is sprayed, effective fire extinguishing may not be performed. In the prior art that discharges water from a helicopter, it is difficult to accurately discharge water unless the helicopter is brought close to the fire site to a certain extent. Is very difficult, and the wind from the helicopter rotor can adversely affect the fire site.

An object of the present invention is to provide a fire extinguishing method using a fire extinguisher that can quickly and effectively extinguish a fire that is difficult to extinguish from a safe place.

[0007]

SUMMARY OF THE INVENTION The present invention provides a fire-fighting munition consisting of a remotely navigable, fire-extinguishing container and steerable wings in a safe location remote from the fire. The fire extinguisher is characterized by remotely guiding a fire extinguisher flying without propulsion toward the place where a fire occurs, and spraying a fire extinguisher from the fire extinguisher by expanding the gas in the container. This is the fire extinguishing method used. Further, the present invention is characterized in that the remote guidance of the fire extinguisher is performed by a wired signal. Further, the present invention is characterized in that the time when the fire extinguisher is sprayed is controlled so as to be a certain time after the detection of the collision of the container. Further, the present invention is characterized in that the fire-extinguishing munition is such that a container filled with the fire extinguishing agent is detachable from a wing used for guidance, and a fire extinguishing agent can be selected according to the type of fire. .

[0008]

According to the present invention, the fire extinguisher is fired at a safe place away from the fire occurrence location, is steered using the wings while flying without propulsion, and the fire extinguisher is remotely directed toward the fire occurrence location. Because it is guided in a specific way, it is possible to reliably hit the place where the fire occurs. Fire extinguishing agents are sprayed from the fire extinguisher guided to the place where the fire occurred by expanding the gas in the container filled with the extinguishing agent. It is possible to extinguish the fire safely and securely without any fire.

Further, according to the present invention, since the fire extinguisher is guided remotely by a wired signal, it is possible to reliably guide the fire extinguisher to the fire spot even in an urban area where there are many noisy radio waves.

Further, according to the present invention, it is possible to control the time when the fire extinguisher sprays the fire extinguishing agent after a certain time has elapsed since the collision detection of the container. Can spray the fire extinguisher.
For example, if a fire is occurring in a building room, the fire extinguisher will break through the windows and walls and enter the room, and then spray the fire extinguisher. Can be sprayed on site.

Further, according to the present invention, since the container filled with the fire extinguishing agent is detachable from the wing used for guidance, an effective fire extinguishing agent can be used by using a fire extinguishing agent suitable for the type of fire. Activities can be performed.

[0012]

FIG. 1 shows a fire extinguishing method according to an embodiment of the present invention, assuming that a fire has occurred in a skyscraper 1. FIG. Fire site 2
Is relatively low, a conventional fire truck such as a pump truck 3 or a ladder truck 4 can extinguish a fire by discharging water. The pump truck 3 and the ladder truck 4 connect the hose 5 to the fire hydrant 6 and perform fire fighting activities from a relatively short distance from the fire spot 2. However, these pump cars 3 and ladder cars 4 cannot perform effective fire fighting activities on the fire site 10 on a higher floor. In many cases, the fire spot 2 is approached from the ground or a water source such as a fire hydrant 6 cannot be easily found.

In this embodiment, a fire extinguishing bomb 11 is fired from a safe place away from the fire source to fire extinguishing activities even at a fire site 10 on a high floor of the skyscraper 1 which is impossible with a ladder truck 4 or the like. It is possible to do. Fire extinguisher 11 is launcher 1
Fired from 2 to fire site 10, fire extinguisher fire engine 1
3 and can accurately hit the fire site 10. When fired from the launcher 12, the fire-extinguishing bomb 11 flies out an extra-fine guide wire 14 and leaves behind. An instructor 15 monitoring the fire site 10 from the roof of the fire extinguisher fire truck 13 gives a wire signal to the fire extinguisher 11 via a guide wire 14, steers the fire extinguisher 11, and guides it to the fire site 10. Such a fire-extinguishing bomb 11 can be guided not only from the ground but also from a helicopter 16 hovering above.

FIG. 2 and FIG. 3 show the structure of the fire extinguisher 11. FIG. 2 is a side view with a part cut away, and FIG. 3 is a rear view. A container 20 is attached to the front of the fire extinguishing bomb 11 having a total weight of, for example, about 15 kg.
Degree of fire extinguishing agent 21 is filled. At the rear of the container 20, wings 22 are arranged. At the rear of the wing 22, the steering wing 2
3 is attached, and can be swingably displaced by the steering device 24. The wings 22 are spread in an X-shape, and the steering wings 23 are oscillatingly displaced, so that a certain direction change is possible during flight. A wire bobbin 25 for feeding out the guide wire 14 shown in FIG. 1 is attached to the base of the wing 22.
The container 20 and the wings 22 are detachable, and the type of the fire extinguishing agent 21 can be selected according to the type and nature of the fire.
For example, a powder fire extinguisher 21 is used for an electric fire.

The fire extinguisher 21 in the container 20 is sprayed by the pressure of the gas generated from the gas generator 26 without explosion of explosives. The fire extinguisher 21 is basically the same as a normal fire extinguisher. A collision sensor 27 is provided at the tip of the container 20, and detects that the fire bomb 11 collides with a window, a wall, a floor, or the like. The fire-extinguishing bomb 11 penetrates the window glass and the like and enters the room.
Rather than spraying the fire extinguisher immediately upon detecting the collision with the window glass, it is more effective to spray the fire extinguisher after it enters the room after a certain period of time without fail. Such adjustment at the time of application of the fire extinguishing agent 21 can be made by delaying the time for operating the gas generator 26 based on a signal from the collision sensor 27 to some extent. In addition, the guide member 15 in FIG. 1 can send a signal for operating the gas generator 26 via the guide wire 14. The guide wire 14 is a very thin conductive wire or optical fiber, and may be cut off when the fire extinguishing bomb 11 breaks the window glass or the like and enters the room. Therefore, when the fire extinguishing agent 21 is sprayed using a delay mechanism or the like. Adjusting is more reliable.

FIG. 4 shows another embodiment of the present invention, in which a fire-extinguishing bomb 51 is fired from the helicopter 16 of FIG.
A launcher 52 is provided at the rear of the helicopter 16 to hover near a fire site and shoot a fire extinguishing bullet 51 while photographing the fire site with a camera 53. Helicopter 1
The remaining fire extinguisher bullets 51 are housed in the airframe of No. 6. Maneuvering of the fire-extinguishing bomb 51 fired from the launcher 52 is performed from the guidance device 54.

FIG. 5 is a simplified cross-sectional plan view of the helicopter 16 of FIG. 4, and FIG. 6 is a simplified side cross-sectional view. When the fire extinguishing bomb 51 is fired from such a helicopter 16, the fire extinguishing bomb 51 can be quickly approached from a fire occurrence site that is not easily approached from the ground, and the fire extinguishing bomb 51 can be reliably fired from a relatively distant and safe position. You can hit the spot. For example, even when a fire occurs in a skyscraper in a city, it is possible to quickly dispatch without being affected by traffic congestion on the ground and perform an effective fire fighting activity. In addition, when ground traffic is difficult or impossible at the time of a major disaster, or in the event of a fire on a marine vessel, fire extinguishing activities can be performed quickly. Furthermore, if an infrared camera is used as the camera 53, guidance at night or the like is easy.

In the above embodiment, the structure of the fire extinguisher is simplified and the amount of fire extinguisher is increased, but the fire extinguisher is equipped with an infrared sensor or the like so that it can be automatically guided to the fire site. Alternatively, a camera may be provided to shoot video for remote control.

[0019]

As described above, according to the present invention, a fire-extinguishing bomb can be guided to hit a fire spot with high accuracy, so that a fire can be reliably extinguished from a distant and safe place. In addition, explosives such as propellants and explosives do not have to be used for the fire extinguisher, so that it can be handled safely.

Further, according to the present invention, since the fire extinguisher is guided remotely by a wired signal, it is possible to reliably hit a fire spot.

Further, according to the present invention, since the time at which the fire extinguisher is sprayed after the collision of the container is detected can be controlled, the fire can be sprayed at an appropriate time in accordance with the state of occurrence of the fire and effective fire extinguishing can be performed.

Further, according to the present invention, since the container filled with the fire extinguishing agent is detachable from the wing used for guidance, the container filled with the appropriate fire extinguishing agent according to various types of fires. If a fire extinguisher is prepared, a fire extinguishing agent can be selected according to the nature of the fire to extinguish the fire effectively and reliably.
