Description

{Throwing type spherical fire extinguisher}

The present invention relates to a novel concept that initially suppresses a fire by throwing at a remote location without a person approaching the vicinity of the fire directly.

In general, powder fire extinguishers are used to extinguish fires in the early stages of a fire. There are various kinds of fire extinguishers that fire powder extinguishing agents by incombustible high pressure gas (carbon dioxide, nitrogen) However, since a separate pressure gas cylinder must be provided inside the container of the fire extinguisher, the structure is complicated and the operation of the user is also difficult.

In addition, since the conventional powder type fire extinguishers are heavy, they are very inconvenient to carry, and when they are used in direct spraying method, they have to be directly accessed to the fire position when the fire is extinguished. Therefore, , And when the fire is distributed over a large area, it is only partially suppressing the edge portion.

Therefore, in recent years, a toe-type fire extinguisher has been developed which allows a person to suppress a fire without approaching a fire scene, and this prior art has a patent publication No. 10-2014-0026590, entitled "Fire extinguisher" .

In the prior art, the medicines reacting with each other are contained in the independent medicament receiving part in the fire extinguisher, and as the lid part is opened, the medicament receiving part is broken inside and the large amount of gas is released in a short time while the two medicines react. The powder is configured to be successful in jet evolution.

However, in the prior art, there is a high possibility that the fire extinguisher will not operate properly because it is difficult to destroy the medicament containing part where a plurality of medicines are isolated and accommodated at once by using the ripper, and the medicament is housed in the case It is very troublesome to fabricate, and the injection rate of the medicine can not be adjusted according to the need, resulting in a problem that the efficiency of fire suppression is lowered.

In addition, since the spherical fire extinguisher rolls, the fire can not be suppressed through the fire point, and the powder is sprayed in a radial direction on the plane, which is not effective for suppressing the fire early.

Disclosure of Invention Technical Problem [8] The present invention provides a technique for blowing a gunpowder in a glass tube ignited through a fuse to reliably burst the glass tube into a reaction tube.

The present invention also provides a technique for easily assembling and assembling a finished assembled detonator in a hemispherical case by inserting a fuse to be connected to the support pipe on both sides of a glass tube loaded with a gunpowder.

The present invention also provides a method of assembling a hemispherical case in which a reaction solution is not inserted into a reaction solution tube installed inside the hemispherical case so that the hemispherical case can be easily assembled in a reduced volume state, And to inject the solution while adjusting the ratio of the solution.

The present invention also contemplates a technique for preventing the spherical extinguisher from rolling over the fire point and fixing the position of the spherical extinguisher so that accurate extinguishing can be achieved by the position fixing protrusion attached to the outer surface of the hemispherical case.

According to the present invention, a fire extinguisher is operated by a firing line without a manual operation by a person, so that a person does not directly go to the vicinity of the fire to become dangerous, and the glass fragments explode, The reaction liquid tube is reliably blown so that the two kinds of reaction liquids react with each other and simultaneously fire the extinguishing liquid and the carbon dioxide to provide an effect of early response to various fires.

Further, according to the present invention, after assembling the assembled disarming device having gunpowder and fuse wire, the assembled disarming device can be easily assembled and installed in the hemispherical case, so that the manufacturing is simple and mass production is possible.

In addition, the present invention can reduce the volume of the reaction liquid tube provided in the hemispherical case without preliminarily putting the reaction liquid therein, so that the hemispherical case can be more easily assembled, and after the assembly is completed, Is injected by adjusting the amount of the fuel to be injected at a predetermined ratio, thereby significantly improving the efficiency of fire suppression.

In addition, since the present invention is made of a spherical shape, when it is poured into a gap between fire wrecks and holes and rolled, the digestion starts from the center rather than the edge of the fire scene to improve the initial fire pressure of the fire, It also has the effect of reducing the risk burden of firefighters working.

In addition, since a plurality of position fixing protrusions are attached to the outer surface of the hemispherical case, the present invention not only helps to roll a suitable distance when rolling, but also fixes the position of the fire extinguisher while melting the position fixing protrusion when exposed to fire or a heat source It provides precise digestion at the point of fire and provides the effect that the digester can work properly even in sloped places.

In addition, the fire extinguishing liquid and the carbon dioxide are injected radially in a three-dimensionally wide manner through a plurality of ejection holes formed through the outer surface of the hemispherical case only by the pressure by the chemical reaction without a separate pressure, thereby suppressing a wide range of fire to provide.
