JP2001149492A - Device for jetting fire-extinguishing water afar - Google Patents

Abstract

PROBLEM TO BE SOLVED: To perform water-jetting fire-extinguishing activities from the ground even in the case of a mountain fire, a skyscraper fire or a fire under a traffic obstructed state due to an earthquake wherein fire-extinguishing activities cannot be performed by a fire-fighting vehicle. SOLUTION: A small amount of gunpowder which explodes by a radio control and water are contained in a container. The container is packed in a magazine, and is fitted in a turret, and is rotated at a high speed. Thus, a high pressure gas is injected and jetted, and the gunpowder is exploded to break the container on a target place, and the water is sprinkled.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for flying fire fighting water to a distant place.

[0002]

[Problems to be Solved by the Invention] Firefighting vehicles cannot use fire extinguishing activities, such as fires in high-rise buildings where water cannot reach the water, fires in forests and earthquakes that make roads inaccessible, etc. May not be possible due to weather or geographical conditions and there is no effective fire fighting.

[0003]

Means for Solving the Problems A container filled with a small amount of explosives exploding wirelessly and water is rotated at a high speed in a gun barrel to disperse the firing load, and compressed air is injected at the rear to eject the container. Fire and explode explosives by radio at the destination, destroy the container with the explosion pressure, spray water and extinguish the fire.

[0004]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is characterized in that a dedicated vehicle is equipped with a magazine mounting device, a compressed air storage, a magazine high-speed rotation device, and a compressed air storage for launching on a gun barrel for flying a container filled with water, and firing. At the site, fix the vehicle, set the direction and angle of the gun barrel toward the destination, place a small amount of radioactive explosives and water in a synthetic resin container that has been treated for noncombustibility, and put this inside. Is placed in a rotating dual-layer magazine and loaded into the rear magazine mounting device of a barrel with a certain length.

[0005] The inside of the magazine containing the container is rotated at a high speed,
A large amount of compressed air is instantaneously injected at the rear, passing through a long barrel with a dug oil groove and high speed rotation to attenuate frictional resistance and firing load, preventing container destruction and stabilizing flight, At the destination point, the explosive in the container is exploded by radio, and the explosion pressure destroys the container and sprays water.

[0006] In order to continuously fire the container, several magazines are mounted, and the container and a water supply vehicle are separately prepared.

Embodiments will be described with reference to the drawings.
FIG. 1 shows a vehicle 1 equipped with a magazine loading device 15, a magazine rotating device 6, a firing compressed air storage 7, an air compressor 10, an injection valve 9, a radio transmitting antenna 2, a compressed air storage tank 4, and a magazine transport fixing machine 14. , A magazine 13, and a barrel 3 fixed to the turntable 11.

In the magazine mounting, when the magazine 13 containing the container 21 transported by the magazine transport fixing machine 14 is received at a fixed position, the front and rear magazine mounting devices 15 are operated by the pressures of the respective cylinders.
And fixed by the magazine fixing device 8 and the magazine transport fixing machine 14.

FIG. 2 shows that the outrigger 16 is extended from the vehicle 1 at the launch site to stabilize the vehicle, and the firing angle of the barrel 3 is determined by the rotation of the turntable 11 and the expansion and contraction of the cylinder 12 for moving the barrel up and down. .

FIG. 3 is an enlarged view in which the magazine 13 is mounted on the magazine mounting device 15. The magazine rotating device 6 of the magazine 13 has a motor equipped with an inverter and gears, and meshes with the teeth of the magazine inner portion 19 to engage with the magazine. 13 to rotate the magazine outer part 1
8 is integrated with the magazine inner portion 19 across the ball ball 27,
For mounting, the outer portion 18 of the magazine is held down by the pressure of the cylinder 20 for moving the magazine mounting device of the magazine mounting device 15, and the cylinder is pulled for demounting.

The container 21 is made of synthetic resin, has a bullet shape, is provided with a water supply port at the rear, and has a screw-in lid 22.

An explosive 24 with a detonator is set in the center of the container 21, and a conducting wire 25 is connected to a copper bar on the edge of the rear water supply port. A copper bar is attached inside the lid 22, and a radio receiver and a radio receiver are provided in the center outside. An antenna 26 is attached, a signal current flows to the explosive, and a load distribution wall 23 is provided to distribute the load caused by high-speed rotation and departure.

FIG. 4 is a sectional view of the magazine fixing device 8, the magazine transport fixing device 14, the magazine inner portion 19, the magazine outer portion 18, the container 21, and the device 6 for rotating the magazine. Similarly, the magazine inner portion 19 also has a corrugated shape. The ball ball 27 is mounted at three places, and the magazine outer portion 1 is formed.
8 is opened only at the place where the magazine rotating device 6 bites the teeth of the magazine inner rotating portion 19.

FIG. 5 is an enlarged view of the injection valve 9 in which a compressed air injection cylinder 30 presses the tip of the injection valve 9 at a right angle.
In order to protect the tip of the cylinder, it is held by a compressed air injection cylinder support bracket 31. For injection, the compressed air injection cylinder 30 is pulled, the injection valve 9 is opened, and the pressing spring 2 is opened.
At 9, after the shock of the injection valve 9 is alleviated and the compressed air is released, the valve is returned by the spring force and the storage of the compressed air in the compressed air storage 7 for firing is started.

FIG. 6 is a sectional view showing a state where the injection valve 9 is closed.

FIG. 7 is a view showing the state immediately after the injection valve 9 is opened and fired.
