Description

Fire extinguishing device for fire fighting}

The present invention relates to a fire extinguishing device, and more particularly, to be installed in a small space where a fire may occur, and when a fire occurs in the small space, stably extinguish the fire at an initial stage, thereby causing damage to property and life due to a large fire. It relates to a fire extinguishing device to minimize the.

In general, various types of fire extinguishing systems are used to extinguish a fire early by setting a control area in a building or an industrial site as a means for the initial fire extinguishing.

Currently used global discharge type fire extinguishing system is connected to water tank on the roof of building, fire extinguishing pipe is installed on the ceiling and sends a signal detected by detector to central processing unit in case of fire. By opening it, water is sprayed through the nozzles on the ceiling to extinguish the fire. That is, when the sprinkler fuse is short-circuited by the generated fire, the fire generated by extinguishing the gas or the extinguishing water filled in the fire extinguishing pipe of the building automatically is initially extinguished.

The conventional fire extinguishing device used in this way causes water and extinguishing fluid to be sprayed to extinguish the fire, causing various electronic devices to get wet, causing expensive electrons due to secondary damage caused by water rather than fire. There was a problem that economic losses such as damage to the product and electronic devices.

As such, gas-based fire extinguishing agents are used to prevent secondary damage caused by water.

Recently, fire extinguishing objects are not limited to simple buildings or the devices and records in them, but are becoming more and more diversified. This is due to the diversification, integration, and high-end of facilities, such as large-scale and high-rise buildings. Electrical panels, communication panels, etc. are more integrated, more complex, and play an important role.

In response to these demands, fire extinguishing systems of various shapes and sizes have recently been developed to provide products that can be applied to individual facilities as well as the entire protection area. It does not meet the requirements of the installation and caused a very difficult problem.

In addition, since the fire extinguishing device is not installed in the prior art, the EPS is installed because the fire extinguishing device is not installed to prepare for a fire that may occur in the case of an individual facility space such as an electric piping (EPS) or a telecom piping shaft (TPS). Or a fire from the TPS created the risk of burning the building.

For example, the automatic fire extinguishing device applied to an individual installation uses a conventional sprinkler nozzle as a discharge nozzle, or uses a similar structure. However, the application of water sprinkler nozzles to gas fire extinguishing agents is not suitable for itself, and the nozzles up to 15 mm reduce the extinguishing performance by excessively shortening the discharge time in a facility storing a small amount of chemicals of 3 kg or less. do. In addition, there is a problem that the radiation characteristics and the angle of radiation is not suitable for gas fire extinguishing agents.

As another example, in the case of applying an automatic fire extinguishing system of 10 Kg or more that protects the entire protection area alone, it must be radiated within 10 seconds in order to ensure the performance and safety of the extinguishing agent because it is a global emission concept. To this end, the diameter of the discharge port must be increased or the storage pressure must be increased. However, sprinkler nozzles having a maximum test pressure of 2.5 MPa have limitations that cannot be secured.

As another example, when a plurality of vessels are installed while protecting the entire protection area alone, the conventional vessel valves do not extinguish fire by individually operating. Therefore, a starting device for simultaneously operating a plurality of vessels is required.

To this end, Korean Patent Laid-Open Publication No. 10-2010-0113301 discloses a starting device for fire fighting equipment using a solenoid valve. The starting device uses a starting container equipped with a solenoid valve, but the starting device must include a sensor for detecting a fire, and a controller for applying an operation signal to the solenoid valve according to the detection sensor. Had to be provided separately.

In particular, the use of the above-described fire extinguishing system for the protection of fires occurring in a small area inevitably caused economic losses, which required countermeasures.

The glass bulb 212b does not withstand the expansion of the thermal expansion liquid after a predetermined time has elapsed and is broken. Then, the support 220b is moved in the right direction based on the drawing, and the pressure of the pressure holding vessel 3 supplied through the main tube 300b is supplied to the needle 104b, and the needle 104b is connected to the supplied pressure. As a result, the copper plate 103b is momentarily moved toward the left in the drawing reference to damage the copper plate 103b. For reference, the pressure supplied from the pressure holding vessel 3 is all transmitted to the needle 104b without being discharged to the outside by the cap 4.

As the copper plate 103b is broken, the gas remaining in the right region of the fluid 102b is discharged to the outside through the valve hole, and the fluid 102b is moved to the right while the extinguishing agent stored in the storage container 2 is prevented. It can be discharged outward through the outlet 101b to extinguish the fire initially.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit of the invention as set forth in the appended claims. The present invention can be variously modified and changed by those skilled in the art, and it is also within the scope of the present invention.
