KR20080055030A - Ignition system of warhead for fire suppression - Google Patents

Abstract

An ignition system of a warhead used for fire suppression is provided to simplify the structure of the ignition system to explode the warhead and explode the warhead on an exact time, so that the reliability of the ignition system is improved. A warhead(1) used for fire suppression is mounted on a launch platform. An electrical signal is transmitted to an ignition part of the launch platform. Electricity is applied to an ignition terminal(7) such that gunpowder contained in a gunpowder vessel(4) is combusted. The warhead is shut if the gunpowder is combusted, and then a wick(3) fixed to a wick fixing member(6) is ignited. The warhead is flown during a time in which the wick is combusted. A blasting powder(2) existing in the warhead and at an end of the wick is exploded.

The present invention relates to an ignition device for a fire suppression warhead, and more particularly, is configured to easily provide a structure of the ignition device that is fired from the launch device of the cannon or aviation to explode the fire suppression warhead.

As is well known, when a large-scale forest fire occurs or a fire occurs in a location where a vehicle or a person is difficult to approach, it is difficult to extinguish the fire and there is no way to extinguish it quickly, which causes enormous damage.

In other words, according to the conventional fire suppression method, the water or extinguishing agent is sprayed only in the required position, and in the case of a large-scale or strong fire, an effective extinguishing may not be possible.

In this case, firefighting helicopters are usually used to extinguish the fire. However, such helicopters are difficult to operate due to dangers during bad weather or at night. The disadvantage is that it is not efficient.

To address these shortcomings, a patented fire fighting warhead has been disclosed.

However, the above-described fire extinguishing warhead has a problem in that an apparatus for exploding a warhead is insufficient or structurally complicated, so that a manufacturing cost of the warhead is expensive.

The ignition device of the fire suppression warhead of the present invention for solving the above problems provides a very simple structure of the ignition device that is fired from the cannon or aviation launcher to explode the fire suppression warhead, from ignition to explosion It is an object of the present invention to provide an ignition device for a fire fighting warhead that can improve its confidence by allowing it to explode without error at a precise time.

The ignition device of the fire suppression warhead of the present invention for achieving the above object is provided with an explosive and a wick for ignition on the inside of the fire suppression warhead fixed to the rear and ignition on the wick and the pill barrel for propulsion And an ignition terminal installed, and will be described in detail below with reference to the accompanying drawings.

1 is a partial cross-sectional view showing the main portion in the fire fighting warhead, Figure 2 is an exploded front view of the fire fighting warhead, Figure 3 is an exemplary view showing an embodiment of the present invention.

The ignition device of the fire suppression warhead is provided at the rear by having an explosive (2) inside the fire suppression warhead (1) filled with the extinguishing fluid (10) and a wick (3) for ignition on the explosive (2). Planted in diaphragm (5) and fixed with fixture (6),

At the rear of the fire suppression warhead (1), the wick (3) is ignited, and a charge container (4) containing a charge for providing propulsion to the fire suppression warhead (1) is provided, (4) is configured by connecting the ignition terminal (7).

In the drawing, reference numeral 30 denotes an aviation launch pad, and 31 denotes an ignition unit of the launch pad.

Referring to the operation of the ignition device of the fire fighting warhead of the present invention as described above in detail as follows.

First, a fire suppression warhead equipped with an ignition device according to the present invention is loaded into a cannon or an aviation launch pad 30.

In this state, the fire extinguishing warhead (1) is fired to the fire site to extinguish the fire.

More specifically, an electrical signal is sent to the ignition unit 31 of the launch pad located at the rear of the fire suppression warhead 1 loaded in the air launch platform 30.

Then, when electricity flows to the ignition terminal 7 to burn the charge in the medicine container 4, the fire suppression warhead 1 is fired from the aviation launch pad 3, and then the shim fixture 6 fixed to the diaphragm 6 The wick (3) fixed to the ignition is ignited and the fire suppression warhead (1) continues to fly to the fire site during the time when the wick (3) is burned.

When the wick (3) is completely burned, the explosive (2) inside the fire suppression warhead (1) and connected to the end of the wick (3) explodes and the fire extinguishing warhead (1) bursts, so that the extinguishing liquid is expelled. This fire will evolve.

The ignition apparatus for the fire suppression warhead according to the present invention as described above is very simple in structure and can be supplied inexpensively, and it is economical and explodes the explosives due to the difference in combustion time depending on the length or thickness of the core material connected to the explosives. Because the warheads were to explode, the firefighting warheads could explode at the correct time, thereby increasing the reliability of the ignition device of the firefighting warheads.

Claims (1)

A wicking fixture (6) installed in the diaphragm (5) provided with an explosive (2) and a wick (3) for ignition in the explosive (2) filled with a fire extinguishing fluid (10) ), An ignition terminal 7 and an ignition terminal 7 are formed at the rear of the fire suppression warhead 1 to ignite the wick 3 and to contain a charge container 4 for supplying a propulsion force to the fire suppression warhead 1. Ignition device for a warhead for fire fighting, characterized in that installed by connecting.
