Abstract

The utility model relates to an automatic fire extinguisher, comprising a plastic film outer layer, in which mud is filled and a supporting board is provided; the supporting board is positioned beneath the hidden danger position of the fire hazard; the plastic film outer layer and the mud are vertically suspended above the hidden danger position of the fire hazard. When the hidden danger of the fire hazard fires at any time, the flare touches the plastic film outer layer, and the plastic film outer layer melts to drip; the mud falls with the plastic film outer layer by the gravity; a cone is formed by the bottom surface of the supporting board to completely cover the hidden danger of the fire hazard to isolate the combustible substance from the flame and the oxygen; the combustion is terminated through the asphyxiation, and the purposes of extinguishing fire and isolating the fire are obtained.

Description

A kind of automatic fire extinguisher

Technical field:

The utility model relates to a kind of automatic fire extinguisher, belongs to fire-fighting domain.

Background technology:

Along with The development in society and economy, the harm that building fire causes for human lives and properties is increasing, thereby is necessary to take certain technical measures in time to control, eliminate spreading of the interior initially fire of various buildings and develop.Fire hidden danger is meant with respect to miscellaneous equipment and is easier to position and the zone in time found of being not easy on fire and hidden, as the place of the connecting portion in the electric wire, power distribution cabinet, distribution box, oil tank, placement combustibles, with fiery zone etc.

Conventional fire attack generally was divided into for three steps: find the condition of a fire, transport extinguishing chemical, put out a fire to save life and property in the scene.Because above-mentioned each link is influenced by all kinds of external factors, often incur loss through delay the fire extinguishing best opportunity, expansion causes damage: as the wrong report of smoke alarm unit or on the shelf for a long time, just as in ornaments, can not reliably report to the police when often really fire alarm occurring, cause fire spreading; Transport extinguishing chemical or fire water-supply as can not in time supplying sufficiently, also delay the time of speedily carrying out rescue work; Be subjected to on-the-spot various condition effect, as large-scale commerce and trade district, underground engineering and skyscraper, even also can't carry out the work of putting out a fire to save life and property rapidly after extinguishing chemical puts in place.In view of the foregoing, the passing in time of little fire develops into big fire easily, and causes heavy economic losses.

The automatic precautionary measures of existing fire, as automatic sprinkler system, owing to do not use for a long time, the equipment working link is many, and perhaps in a single day power supply interrupts in fire incident, and equipment dependability is not high.Except that above-mentioned defective, if CO may damage near personnel at error starting at ordinary times, so security can not get ensureing.

Fixation such as fire guard, fire prevention groove box, fireproof paint, anti-chamotte are having position on fire from explosion will obviously reduce flameproof effect.

Summary of the invention:

The utility model can be eliminated fire incident in bud the on-the-spot realization of the fire hidden danger self-extinguishing of fixed position.

For achieving the above object, the concrete technical scheme that the utility model adopted is:

A kind of automatic fire extinguisher comprises a plastic foil skin, an inner filling silt and a supporting plate, and supporting plate is positioned under the fire hidden danger place, and plastic foil skin and silt vertical hanging are in the top at fire hidden danger place.

Further comprise a metal grill, be positioned at outside this plastic foil skin and be fixed on fire hidden danger place top.

This supporting plate is engine firewall or floor.

The integral body that this silt and this plastic foil skin are constituted should be greater than the projected area of fire hidden danger on this supporting plate in the projected area on this supporting plate.

This silt is closed in this plastic foil skin.

This silt can be the powder or the particulate matter of not flammable or difficult combustion.

Silt and plastic foil skin suspend between area of fire protection.

The utility model can start fire extinguishing in the time the earliest, realize fire extinguishing in the shortest time, and cost is low, can positioning fire-extinguishing.

Description of drawings:

Fig. 1 is the utility model automatic fire extinguisher structural representation.

Embodiment;

As shown in Figure 1, the utility model automatic fire extinguisher comprises a plastic foil skin 40, an inner filling silt 50 and a supporting plate 10.Automatic fire extinguisher hangs on the top at fire hidden danger place 20, and fire hidden danger place 20 is positioned on the supporting plate 10.Fire hidden danger place in the present embodiment is the joint of cable 30.Be appreciated that fire hidden danger place can also be the place of power distribution cabinet, distribution box, oil tank, placement combustibles, with the fixing point of origin in positions such as fiery zone.It is engine firewall, floor or other supports that supporting plate 10 also can be understood as.

When fire hidden danger 20 on fire at any time; when flare was enough big, plastic foil skin 40 was with the fusion drippage, and silt 50 falls by gravity thereupon; with supporting plate 10 is that the bottom surface forms a cone; fire hidden danger 20 is all covered, combustible and flame, oxygen are kept apart, stop burning by suffocating; isolate with cable 30 simultaneously; reach the purpose of fire extinguishing and fire insulation, stop fire spreading, thus protection cable 30.

The quantity of silt 50 is advisable can cover fire hidden danger 20 after falling fully, the integral body that silt 50 and plastic foil skin 40 are constituted should make the weight and volume of silt 50 be enough to cover flame and air-isolation greater than the projected area of fire hidden danger 20 on supporting plate 10 in the projected area on the supporting plate 10.Big more as fire hidden danger 20 areas, the projected area of corresponding requirements plastic foil skin 40 on supporting plate 10 is big more.

The thickness of plastic foil skin 40 can not break naturally with weight that can long-time bearing silt 50 and be advisable, and the available metal grid is installed on outer 40 belows of plastic foil, and grid is support with other fixed part, the weight of auxiliary carrying silt 50.

The distance of plastic foil outer 40 and fire hidden danger 20 can be burnt plastic foil skin 40 at short notice with the flare of initial fire and is advisable.

Fly upward for preventing that silt 50 is met travel fatigue soil at ordinary times, silt 50 top seals can be packed.

It is the powder or the particulate matter of not flammable or difficult combustion that silt 50 can be understood as.

This device also can be used for the fire insulation between several area of fire protection in the same building thing except being applied to the pointing fire-extinguishing of fire hidden danger 20, comprises the shutoff of vertical shaft.The silt and the plastic foil skin of big projected area are suspended between the area of fire protection.When a certain fire district was on fire, owing to scurry on the flare, heat was excessive, and the plastic foil skin will melt, and caused silt to fall, thereby had formed the silt heap of buffer action outside fire district on fire, ensured that the fire district adjacent with fire district on fire is unaffected.

Need to prove; particular of the present utility model is described in detail the utility model; for a person skilled in the art, in the various conspicuous change of under the situation that does not deviate from spirit and scope of the present utility model it being carried out all within protection domain of the present utility model.
