The present invention relates to a fire detection and extinguishing apparatus that detects heat in the event of a fire in a facility such as an enclosed space or a conditionally enclosed space, that is, a compartment and a valuables storage box, a television, a computer, and the like. .

BACKGROUND ART Conventionally, a body having a discharge port, a propellant for generating extinguishing material, and a fire extinguishing apparatus having a fuse are known. (British report NO 2028127, class A62 C13 / 22 NKE A5A, 1980). This device is designed to ignite the fire when the fuse is activated, ignited by a flame or solid fuel propellant, and extinguishing combustion gases entering the fire zone through the outlet. It was so large that it could not be used for fire fighting in small spaces.

In addition, the components that make up the aerosol (AEROSOL) and equipment for fire detection and large-scale fire suppression are well known. (Report WO 92 17244 published October 15, 1992) The plant can be used not only as a fire suppression system but also as an individual fire extinguisher itself.

It consists of a thin protective channel membrane (vibration membrane) that blocks the discharge hole and a cylindrical body. There is an aerosol-generating propellant in the body covered by the cap. The fuse, a means of activating the propellant at the same time as the fire detection, is located inside the body and partly out.

The inability to control the temperature for aerosol flow and distribution from fire suppression is a major obstacle to using this facility.

In order to solve the above problems, the fire suppression aerosol generator for extinguishing a fire in a small facility can reliably maintain the distribution and vibration load of the aerosol in an optimal state so that the scale of the fire no longer increases. According to the size of the fire, the distribution and vibration load of the aerosol injection are uniform, so that the equipment can be surely maintained in the best state.

In addition, features that reduce the aerosol injection time and maintain the distribution of the aerosol injection in optimum conditions in tight spaces are provided by the following.

Cup-shaped body with flange (2)

Round pipes and plugs provided on the flange or surface in the middle

-Length (L) and height (H) of channels

The other important feature is to ensure that the cooling effect is ensured without the addition of functional elements and the overall increase in equipment.

Features of the present invention are as follows.
A fire detection and suppression system comprising a cylindrical body with a stopper, a release hole covered with a membrane, an aerosol component contained in the body, and a sensing and igniting substance in the form of a fuse (6), with a flange (2) Cup-shaped body (1), the discharge hole is a circular channel, a circular space is formed in the middle of the flange body,

A cylindrical space is defined by the aerosol-forming propellant 4 and the cover 3, the ratio of the length L to the height H of this channel is preferably 2-10, and the cover 3 and The channel defined by the aerosol-forming propellant 4 is further provided with a gas coolant 5. A discharge hole is formed in the side of the channel, ie in the circular space defined by the flange 2 and the lid 3 provided on the cylindrical body 1.

The gas coolant 5 is pulverized between the intermediate inserts, ie in the form of granules, which ensures improved reliability for fire detection and operation of the extinguisher after moving.

The membrane is in the form of a dense wire mesh to keep the vibration load stable. Technically suitable at the work site is possible because the fuse 6 exits the body through the stopper or cup bottom or through a circular gap.

Spigot-shaped lead knots are preferred.

The lead 6 exiting the trunk 1 may be additionally sheathed 10. For example, it can be sensitive to heat to increase the detection effect at the point of fire.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

2 is a plan view of the present invention;

As shown in Figures 1 and 2, the proposed mechanism is a structurally flat cylindrical box-shaped torso (e.g. 40mm in diameter, 40mm in height, 65mm in diameter).

The trunk 1 is in the form of a cup with a flange 2. The body 1 has an aerosol-forming propellant 4 and the cover 3 is installed at a distance from the flange 2 with the channel space therebetween, and the flange 2 and the cover 3. Aerosols are released through the release holes in the circular space defined by. The ratio of the length L to the height H of the channel is preferably less than 10, more preferably about 10 to 2. The height H of the channel here means the height of the cylindrical space defined by the aerosol-forming propellant 4 and the cover 3, and the length L of the channel is the left and right distance of the channel in the figure of FIG. Diameter).

The gas coolant 5 enters the body 1 via the plate 8. The lead 6 is fixed to the propellant 4 and covered with a protective channel membrane 7 and exits through the cylindrical channel through the plug 9.

Some of the conductive wire (6) coming out of the body is preferably additionally coated (10) to be sensitive to heat.

Materials used in the present invention are as follows.

-Aerosol-forming component, manufactured under the trademark SEPT, technical specification 4851-019-04973366-01

-Fuse, manufactured from TC 7275-001-51953776-00

-Heat sensitive component, made from CX3-21, TC 6-03-408-80

Three instruments were prepared according to the experiment type according to each example. All samples were automatically activated when the ambient temperature reached 180 ° C or when the flames were directly in contact with the combustor. The results are shown in Table 1 attached.

The instrument with the body 1 is protected and fixed with a cover 3. The thermal shock is transmitted to the aerosol-forming propellant 4 along the fuse 6 and after the combustion of the working surface, the extinguishing aerosol is secreted through the cylindrical protective channel membrane 7. Here, the protective channel film 7 is a metal mesh, for example, in a cylindrical shape so that the inner surface of the channel and the discharge holes are partitioned as shown in FIG. It is shaped. That is, the aerosol-forming propellant 4 ignited by the fuse is provided by the flange 2 and the cover 3 via the protective channel film 7, for example, coming out through the channel together with a granular gas coolant. It is emitted through the discharge hole.

The fire extinguishing capacity of the instrument was measured in a specific closet. The wardrobe is 600 in width, 500 in height, 400 mm in depth, and 120 L in volume. A fire extinguisher with a hole in the form of a cylindrical channel was fixed with a lid on the top of the closet. On the bottom of the closet, a piece of cloth 30 × 30 cm was moistened with 27 ml of gasoline A-76.

When the gasoline being evaporated was set on fire, heat shock was transmitted to the fuse 6, and the operation of the mechanism was performed. Experiments showed positive results as the model fire zone was fully extinguished.

The transport and vibratory load durability checks of the instrument were made in accordance with government standard B25147-82 and industry standard 84-1855-80. The operating time of the vibration load was 0.5-1 hour at 7.5 hz frequency.

The results of the experiment showed that the instrument with parameters consistent with the examples in 1,2,3 survived the specified weight without damage, and the fire extinguishing test completely extinguished the model fire zone. When the instrument was tested according to the sample under similar conditions, the combustion of the zone did not occur in two of the three experiments.

The present invention detects heat in the event of a fire in an enclosed space or conditionally enclosed space, that is, a compartment, a valuables storage box, a television, a computer, or the like, so that the fire can be suppressed at an early stage to prevent a large spread of fire. It can work.
