Abstract
An automatic powder fire-extinguishing device is provided, which comprises a cylinder shell 1 and a shell cover 2 which are sealed and covered together. The cavity of the utility model is filled with gas generator 4 and fire-extinguishing powder 3 which plays the role of fire-extinguishing startup, and forms a structure of gas generator layer to dry powder layer to gas generator layer. The weight proportion of gas generator 4 and dry powder 3 is 0.5 to 1.55 to 9. In actual use, once the environmental temperature exceeds the standard, a great deal of gas is generated and exploded, which makes the dry powder sprayed on fires for fire extinguishing. The device can be configured and installed conveniently and flexibly, is not subject to the restriction of sites, and has advantages of short startup time and good effect, being able to stamp out fires when the fires just break out.
Description
Technical field
The utility model relates to a kind of fire-fighting equipment, especially a kind of automatic fire extinguisher that utilizes dry powder to stamp out a fire.
Background technology
Traditional building is set up fire-fighting equipment and mostly is foam annihilator, and it has two defectives at least, and the one, the chemical attack effect is arranged, the 2nd, its installation is limited by the place.For example industrial plants, office building, warehouse, home-use room, cable duct, basement and garage etc., especially the front and back sealing chamber of equipment cabinet, automobile, all be fire when taking place people press for the place that arrives and be difficult to arrive.If but can not in time put out a fire, in case fire spreading will cause enormous economic loss and casualties.For this reason, install in place that these fire fighters are difficult to reach the spot and place can self-extinguishing device, just become social a kind of special demand, demand was put out it in bud early at the initial stage of finding the condition of a fire.
The utility model content
The technical problems to be solved in the utility model is, a kind of dry powder automatic fire extinguisher is provided, the configuration of this extinguishing device and easy for installation flexible is not subjected to the place restriction and can be about to fire suppression in bud at the initial stage of finding the condition of a fire in self-extinguishing on the scene of a fire.
Technical solution of the present utility model is, described dry powder automatic fire extinguisher referring to Fig. 1, has the tubular cap 2 of cylindrical outer casing 1 and its barrel dliameter size and the barrel dliameter size coupling of shell 1, and described shell 1 and described cap 2 are closed and cover pipe and connect.Described shell 1 intracavity bottom and cap 2 intracavity bottoms are filled with the gas-forming agent 4 that one deck plays fire extinguishing startup effect respectively, recharge one deck fire extinguishing on the described gas-forming agent 4 with dry powder 3, make the lumen shaft of the tubular article of forming by shell 1 and cap 2 after the sealing form the structure of gas-forming agent layer one dry powder layer one gas-forming agent layer to an end to the other end.Described gas-forming agent 4 is 0.5～1.5: 5～9 with dry powder 3 weight proportion ratios in regular turn.
When dry powder automatic fire extinguisher of the present utility model uses, can be provided with one according to the different situations of different places and be placed on and be used for fixing the dry powder automatic fire extinguisher on the wall.The configuration of this dry powder automatic fire extinguisher also can be formulated different specifications according to different demands.As the high temperature place in the little space of this enclosed type of car engine unit room, can select to adopt the higher gas-forming agent of start-up temperature value as starting agent, for example the start-up temperature value is the gas-forming agent of 160 ℃ or 200 ℃.The place that environment temperature such as warehouse, shelter is lower then should be adopted and be started the lower gas-forming agent of temperature value as starting agent.It is in the above-mentioned extinguishing device that the gas-forming agent of dry powder that this device will be used to put out a fire and certain volume ratio places the cylindrical outer casing 1 of sealing and the tubular article of tubular cap 2 compositions.When environment (scene of a fire) temperature exceeding standard, produce a large amount of gases after the gas-forming agent decomposes, cylinder pressure increases rapidly, the tubular article explosion, dry powder immediately spreads and is sprayed at also realizes self-extinguishing thus on the scene of a fire.
The beneficial effects of the utility model are that the configuration of dry powder automatic fire extinguisher and easy for installation flexible is not subjected to the place restriction and can be about to fire suppression in bud at the initial stage of finding the condition of a fire in self-extinguishing on the scene of a fire.The employed gas-forming agent decomposition temperature of this extinguishing device is suitable, and start-up time is short, starts reliability more than 90%.And be easy to make, demolition effect is good, and is very favourable to safety.
Description of drawings
Fig. 1 is the structural representation of a specific embodiment of the utility model dry powder automatic fire extinguisher, is denoted as among the figure:
The 1-shell,
The 2-cap,
3-dry powder,
The 4-gas-forming agent.
Fig. 2 is shell outside the dry powder automatic fire extinguisher/cap bottom interior surface structure reference diagram.
The specific embodiment
Embodiment 1, and referring to accompanying drawing 1, this embodiment of the utility model dry powder automatic fire extinguisher thickness of drawing materials is that the aluminum alloy thin profile material spinning of 0.04mm is made shell 1, and this shell 1 is tubular, and the cross section is circular, and diameter is 68 millimeters of ￠.Cap 2 also is tubular, and the cross section also is circular, and its barrel dliameter size is mated with the barrel dliameter size of shell 1.Tubular cap 2 and cylindrical outer casing 1 are closed coaxial line screw thread and cover pipe and be connected into one, closely cooperate, and reach is greater than 3 millimeters.Cover pipe and connect the tubular article that the cap 2 that is one and shell 1 are formed, long 80mm, its lumen shaft to an end to the other end, be filled with one deck in regular turn and play the gas-forming agent 4 of fire extinguishing startup effect, one deck fire extinguishing dry powder 3, and then one deck gas-forming agent 4, compacting, be full of, make the structure that forms gas-forming agent layer one dry powder layer one gas-forming agent layer in the housing of the tubular article of forming by shell 1 and cap 2 after the sealing thus.Shell 1 is smeared epoxide-resin glue with surface, cap 2 threaded connection place, treats promptly to make product after resin glue solidifies.For preventing to produce the fragmentation accident, referring to Fig. 2, shell 1 can be delineated quincunx indentation respectively with the bottom interior surface of cap 2.It is the QF3100-3 type gas-forming agent of 200 ℃ commercially available Chinese Guangdong province riverhead county training group banger factory production that above-mentioned gas propellant 4 adopts the start-up temperature value, and a kind of gas-forming agent very responsive to design temperature is as starting agent.Above-mentioned dry powder 3 also adopts the powerful powder extinguishing agent of Phoenix brand MHF100-4A type of above-mentioned commercially available training group banger factory production.Can be 0.5～1.5: 5～9 in regular turn as gas-forming agent that starts agent and dry powder weight proportion ratio as extinguishing chemical, described gas-forming agent 4 is 1: 7 with dry powder 3 weight proportion ratios in regular turn.This routine dry powder automatic fire extinguisher especially is fit to the enclosed type scene of a fire, as the usefulness of the front engine bin fire extinguishing of automobile.
On probation to be proved to be effect remarkable through manufacturing experimently for the dry powder automatic fire extinguisher of the present utility model of Gou Chenging thus, reaches designing requirement fully.This device profile can be diversified, can adopt the different gas-forming agent of various temperature value as starting the needs that agent adapts to multiple place, and it starts inertia and is no more than 50 seconds, start highly sensitive, start reliability and reach more than 90%, do not have destructive fragmentation and produce, and reduced cost.
