Abstract
The utility model discloses a pitching forest extinguisher comprising a sealing extinguishment chemical container with super fine dry powder fire extinguishing chemical and a gas producer which consists of an actuating apparatus and a gas produce container with foaming agent, the actuating apparatus is provided out of the extinguishment chemical container and contacting connect with the foaming agent, several fumaroles are equipped on the sidewall of the gas produce container and partly equipped in the extinguishment chemical container. Compared with the prior art, the utility model has the outstanding advantages of: (1) simple structure, multiple initiate mode, easy to use, (2) high extinguishment efficiency, low fired, moderately surface fire, naked fire and dark flame can be extinguished, (3) Light weight, capable for heavy conveyance to fire hazard on-site.
Description
Technical field
The utility model relates to a kind of extinguishing device, relates to a kind of hand-throw type forest extinguishing device especially, belongs to the fire prevention field.
Background technology
Forest fire is that natural calamity wide, that harmfulness big, the disposal relief is extremely difficult takes place in the world.Because of reasons such as global warmings, forest fire frequency and loss are all in rising trend in the world in recent years.China is the country of forest fire pilosity, it is reported, the forest fire of putting out a fire to save life and property will drop into a large amount of man power and materials, because the people is necessary and scene of a fire close contact, makes the life danger coefficient of firefighters increase.And will thoroughly put out big fire, what need is chronic.How to put out a fire to save life and property effectively that forest fire, short-term put out a forest fire is a global difficult problem together always.Usually the means of putting out that adopt are wind-force extinguisher and water system fire-fighting bomb for forest dual mode in recent years, wherein:
Wind-force extinguisher dispels just blowing away at burning fire seedling, the tongues of fire by its powerful wind-force (more than nine grades), the combustible gas concentration that trees are brought into play is broken up dilution, make it to form new flare, on the one hand continuous again wind-force can be taken away heat, and the plant temperature of burning is reduced until being cooled to below the burning-point, thereby reach the purpose of fire extinguishing, this mode is to putting out weak fire, the moderate surface-fire, and effect is better, but can only extinguish open flame, dying fire can not go out;
The water system fire-fighting bomb for forest is that airborne fire extinguisher bomb is thrown in fire zone, utilize body blast back water droplet to spray and impact knock down the flame to all around, this method belongs to the physics fire extinguishing, not only fire extinguishing is renderd a service limited, and because the quality of single bullet is all bigger, in short time a large amount of water system fire-fighting bomb for forest is transported to the scene of fire and has big difficulty, thereby extinguishing ability also has been subjected to bigger restriction.
Summary of the invention
The utility model promptly is a kind of hand-throw type forest extinguishing device that proposes at the shortcoming that exists in the above-mentioned prior art, and this fire extinguisher has multiple Starting mode, and the scene of fire is erupted fire extinguishing automatically, and is easy to use.
The utility model is realized by following technical proposals:
A kind of hand-throw type forest extinguishing device, comprise the sealing-off fire agent paint storage tank that ultra-fine dry powder extinguishing agent is housed, with a gas generator, described gas generator comprises starting drive and the gas generation container of gas-forming agent is housed, it is outer but be connected with described gas-forming agent contact that described starting drive is arranged on the extinguishing chemical paint storage tank, described gas produces container side wall and is provided with several gas eruption holes, and described gas produces container gas eruption bore portion and is arranged in the extinguishing chemical paint storage tank.
Further, described starting drive is the superconduction heat-sensitive line.
Further, the extension spring that to be an end be connected with the gas-forming agent contact of described starting drive and with the extension spring tube of extension spring tight fit and fixed-site.
Further, described extension spring end is provided with the extension spring ring.
Further, described starting drive outer end is provided with protective cover.
Compared with prior art, the utlity model has following remarkable advantage:
(1) simple in structure, have multiple Starting mode, easy to use;
(2) fire-fighting efficiency height can not only put out weak fire, the moderate surface-fire, and naked light can also put out dying fire;
(3) in light weight, be suitable for transporting in a large number the scene of fire.
Description of drawings
Fig. 1 is the structural representation of the utility model hand-throw type forest extinguishing device embodiment one;
Fig. 2 is the structural representation of the utility model hand-throw type forest extinguishing device embodiment two.
The specific embodiment
The utility model is further introduced below in conjunction with the drawings and specific embodiments, but not as to qualification of the present utility model.
Embodiment one:
With reference to shown in Figure 1; hand-throw type forest extinguishing device comprises fire extinguisher paint storage tank 1; gas produces container 2; wherein fire extinguisher paint storage tank 1 is an airtight cylindrical shell; ultra-fine dry powder extinguishing agent is equipped with in inside; gas produces the inside that container 2 is arranged on fire extinguisher paint storage tank 1; it is a cylindrical vessel; sidewall is provided with some gas eruptions hole 21; gas-forming agent is equipped with in inside; chemical substance such as receive as: nitrogenize; the upside that produces container 2 at gas is set with one extension spring tube 4 is set; be provided with an extension spring 3 in the extension spring tube 4; the end of extension spring 3 and gas-forming agent remain contact and are connected, and extension spring 3 is tight fit with cooperating of extension spring tube 4, the bigger frictional force of generation when guaranteeing relative motion between the two; more convenient when guaranteeing that extension spring 3 is pulled out; can one spring-pulling ring 5 be set at its free end,, a protective cover 6 can also be set in extension spring 3 outer ends in addition for fear of the external force maloperation.
When breaking out of fire; destroy protective cover 6 earlier; expose spring-pulling ring 5; pull out extension spring 3 by spring-pulling ring 5; then hand-throw type forest extinguishing device is dropped into the scene of a fire; extension spring 3 is pulled out in the process and is rubbed with extension spring tube 4; produce a large amount of heats; extension spring 3 heats up rapidly, and by end heat is transmitted the gas-forming agent nitrogenize and receive, and nitrogenize is received chemical reaction generation nitrogen is taken place thereupon; ejection from the gas squit hole 21 of gas generation container 2 sides; under the effect of gases at high pressure, the ultra-fine dry powder extinguishing agent eruption in the fire extinguisher paint storage tank 1 is put out a fire.
Embodiment two:
