Hereinafter, we will look at the specific technical details regarding the fire extinguishing device for small spaces according to the present invention along with the drawings.

As shown in Figures 1 to 6,

The fire extinguishing device (1) for small spaces according to the present invention is

A hollow tube (11) made of thermoplastic resin,

A fire extinguishing agent (12) filled inside the tube (11),

A fire extinguishing tube (10) including a cap (13) sealing both ends of the tube (11);

A tube storage unit (21) for mounting the fire extinguishing tubes (10) individually or in multiples of two or more,

A fire detection unit (22) that detects the occurrence of a fire through a temperature sensor and a smoke sensor,

A lower case 20 including a communication unit 23 that transmits fire information transmitted from the fire detection unit 22 to a safety manager;

It includes an upper case 30 that covers the upper front of the lower case 20 and has a plurality of fire extinguishing gas ejection holes 31 formed on the surface.

The thermoplastic resin forming the tube 11 is one or two or more types selected from PE, PP, nylon, ABS resin, Teflon, or silicon, and is used as a fire extinguishing agent (12) depending on temperature and pressure. Due to expansion, the tube 11 bursts or melts due to heat, causing fire extinguishing gas to be ejected to the outside to extinguish the fire. Figure 7 exemplarily shows a state in which the surface of the tube 11 is melted by heat and extinguishing gas is ejected.

The material that makes up the tube 11 has different characteristics to withstand temperature and pressure depending on its type, and by utilizing these characteristics, the time at which the fire extinguishing gas is ejected in the event of a fire can be changed to allow the extinguishing gas to be ejected in multiple stages. there is. When fire extinguishing gas is ejected in such a multi-stage manner, it has the advantage of enabling complete extinguishment by extinguishing the resurgence of the fire.

That is, the tube storage unit 21 is equipped with a fire extinguishing tube 10,

By mounting a fire extinguishing tube (10) made of the same material selected from PE, PP, nylon, ABS resin, Teflon, or silicon, the extinguishing gas ejection time according to temperature and pressure is equalized, or

Alternatively, fire extinguishing tubes (10) made of different materials are mounted to vary the extinguishing gas ejection time according to temperature and pressure.

More specifically,

The tube storage unit 21 is equipped with a fire extinguishing tube 10,

A fire extinguishing tube made of different materials so that fire extinguishing gas is ejected in a temperature gradient range of 80 to 100 ℃, 180 to 220 ℃, 380 to 420 ℃ and 580 to 620 ℃ depending on the characteristics of the material making up the tube 11. (10) can be mounted.

The tube 11 constituting the fire extinguishing tube 10 is characterized in that the inner diameter is 0.5 mm to 30 mm, the outer diameter is 0.7 mm to 40 mm, and the length is 1 mm to 1,000 mm.

If the inner diameter, outer diameter, and length are kept below the above-mentioned ranges, the filling space for the fire extinguishing agent may be too narrow and the fire extinguishing function may be weak in the event of a fire. If it exceeds the presented ranges, the overall scale of the device may be increased. Therefore, it may not be suitable for use in enclosures or small spaces such as distribution boxes, distribution boxes, communication boxes, communication rooms, small warehouses, cabinets, and energy storage systems (ESS), which are closed spaces. Therefore, the inner diameter, outer diameter, and length are as specified above. It is desirable to keep it within the range.

The ratio of the inner diameter to the outer diameter determines the thickness of the tube 11, and if it is maintained below 0.2 mm, which is the minimum thickness determined by the outer diameter and inner diameter, it can be extinguished in the event of a fire due to surface damage due to external environmental factors. There is a risk of chemical leakage, and if the maximum thickness of 30.5 mm is exceeded, the surface of the tube may not burst or melt at the appropriate time for fire suppression, and the time at which fire extinguishing gas is ejected may be delayed. It is desirable to limit the thickness of the inner diameter and outer diameter within the suggested range.

The fire extinguishing agent (12) fills the tube (11) with a liquid halon fire extinguishing agent or a reactive fire extinguishing agent and covers both ends of the tube (11) with a cap (13). When a fire breaks out, the fire extinguishing agent (12) is used. When the fire extinguishing agent expands or the tube melts, the fire extinguishing agent is ejected as gas and plays a role in extinguishing the fire.

More specifically, pentafluoroethane (CHF ₂ CF _3, HFC-125), brominated trifluoromethane (CF ₃ Br, Halon 1301), 2,2-dichloro-1,1,1-trifluoroethane. (CHCI ₂ CF _3, HCFC-123), chlorotetrafluoroethane (CHCIFCF _3, HCFC-124) or 1,1,2,2,4,5,5,5-nona fluoro-4(trifluoromethyl )-3- Pentanone (1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone, FK-5-1-12) Each species can be used alone or two or more species can be used in combination.

A fire detection unit 22 including a temperature sensor 221 and a smoke sensor 222 is installed on the upper part of the tube storage unit 21.

The fire detection unit 22 may be equipped with additional necessary sensors, such as a flame detection sensor, in addition to the above sensors.

Through the fire detection unit 22, smoke or temperature generated when a fire initially occurs is detected, and the fire information detected in this way is transmitted to the communication unit 23 and notified to the safety manager as an alarm to respond to the fire. Make sure this can be done quickly and early on.

In addition, fixing members 24 are provided at the upper and lower ends of the lower case 20 so that the small space fire extinguishing equipment 1 according to the present invention can be easily installed at a desired location through a coupling means such as a bolt. is formed

As shown in FIGS. 1 to 6, the upper case 30 covers the upper entire surface of the lower case 20, and has a plurality of fire extinguishing gas ejection holes 31 formed on its surface.

The fire extinguishing gas blowing hole 31 can have various shapes, and as an example, Figure 5 shows another type of fire fighting gas blowing hole 31.

The fire extinguishing gas coming out of the tube 11 is ejected through the fire extinguishing gas blowing hole 31.

The fire extinguishing equipment for small spaces according to the present invention is made up of tubes of the same material or different materials among tubes of different materials with different ability to withstand temperature and pressure and installed in an indoor space, so that when a fire occurs, the fire extinguishing equipment is installed in an indoor space. By allowing fire extinguishing gas to be ejected as the tube bursts or melts, it is possible to effectively respond to initial fire suppression,

It has the advantage of being able to expect a perfect fire extinguishing effect by effectively extinguishing the resurgence of a fire by constructing a fire extinguishing tool by mounting tubes of different materials that have the ability to withstand temperature and pressure, so it has great industrial applicability.
