Description

Large-capacity Automatic Fire extinguisher with improver usability}

The present invention relates to a fire extinguishing device, and more particularly, to an automatic fire extinguishing device that increases the fire extinguishing capacity so as to be applicable to large spaces and is applicable to moving means such as automobiles.

Generally, sprinklers are installed indoors to extinguish fires. The sprinkler is designed to detect the room temperature and spray water when the room temperature reaches a preset temperature or higher. Here, the sprinkler receives water through the pipe, but if the valve of the pipe is closed, water cannot be sprayed. In other words, even if the indoor temperature is higher than the preset temperature, if the valve of the pipe is closed, the sprinkler cannot function.

In addition, when the weather becomes cold, such as in winter, there is a risk that the pipe may freeze, and even in this case, the sprinkler cannot function properly. In addition, the sprinkler has a problem in that it is possible to extinguish a fire only within an angle in which water is sprayed, and it cannot extinguish a fire outside the angle in which water is sprayed.

In addition, in the case of an electric fire that accounts for a significant part of the cause of the fire, most fire extinguishing facilities are installed on the ceiling and are far away from the ignition point, which leads to a large fire due to early detection and initial suppression in the event of a fire. There will be a lot.

To this end, registration patent No. 10-1899102 "automatic fire extinguishing device" by the present applicant has been disclosed, but it cannot be applied to large spaces due to its limited fire extinguishing capacity and relatively low performance, and is applicable to transportation means such as automobiles. There is a tough problem.

In addition, the conventional automatic fire extinguishing device has a problem in that the place or use that can be utilized is limited and the fire extinguishing capacity is small, so that it cannot be used and used in various ways, and can be applied only to a narrow field and preset conditions.

The present invention is not limited to the embodiments described herein, and may be implemented in various different forms. In order to clearly describe the present invention, parts irrelevant to the description have been omitted, and the same reference numerals are attached to the same or similar components throughout the specification.

First, the agent and the fire extinguishing agent used throughout the specification of the present invention are the most important components of the fire extinguishing device according to the present invention, and are liquid substances that directly extinguish a fire. Therefore, even if it is used interchangeably as an agonist and an agonist, its meaning does not change, and even if it is used as an extinguishing agent or extinguishing agent, it can be interpreted identically in terms of its composition. In addition, the agonist and the fire extinguishing agent may be differentiated or used separately according to their roles and functions, and may be used as the same one in some cases.

As shown in Figs. 1 and 2, an automatic fire extinguishing device 1 by the applicant of the present invention has been disclosed. According to this, it is characterized in that it is automatically opened as a fire extinguishing device for obtaining an expansion spray effect depending on the vaporization of the fire extinguishing agent and the melting temperature condition of the nozzle. However, according to the structural characteristics and the operation of the extinguishing agent, the disclosed automatic fire extinguishing system cannot but be used in small quantities, and its usability and applicability are limited.

Here, the preset condition refers to the difference in temperature conditions between the melting member and the liquid substance to be vaporized, and this may be changed or added according to the place where the fire extinguishing device is to be installed and environmental characteristics.

In addition, the agonist 600 may be made of the same material as the extinguishing agent 110, and thus, both the storage unit 100 and the nozzle 300 in the pipe 200 may be filled with the same material. May be.

로 마련될 수 있다. In addition, the working material 600 may be made of a material different from the extinguishing agent 110. The extinguishing agent 110 is prepared as a liquid extinguishing solution generally used in the related art, and the agent 600 contains a halogen compound, but the structural formula of the main component is
