Method for fire prevention and extinguishing of forest fires
To increase the reliability of protection to the protected area, prevention of proliferation of fires, more reliable and efficient extinguishing of fires occurred and fires the protected forest and the territory of the way of prevention and extinguishing of forest fires includes identifying the most fire-hazardous areas of woodland, defining the outline of the array and the calculation of the required agnathavasam agent and agent warning fire and spread of fire. After performing such operational works contoured land supply agnathavasam material in the form of a flat elongated flexible coaxial sleeve, the annular gap which is placed the material possessing the property of accumulation of a significant amount agnadema fluid; volume akkumulirovannaya fluid locally distributed on the skeletal structure of the material, which prevents the flow of any leakage of this fluid without performing work on ohnataly, i.e., the emission agnadema fluid occurs only when there is a fire hazard situation in which part of the wall of the coaxial sleeves burns and peregrinations fire the sleeve length is preserved intact the entire volume of liquid, who is retained to perform similar work during fire-fighting other fires in the controlled area of the forest. 5 C.p. f-crystals, 5 Il.
The invention relates to techniques and technologies to prevent fires and methods of extinguishing such fires and can be used for the prevention and control of forest fires and fires of any kind.
Currently known fundamental areas of technical solutions in this field of human activity, one of which is a method of fire prevention and extinguishing of forest fires, including accommodation agnadema installation in potentially flammable array, bringing the installation to the emergency operating state, tracking the status of the array on the light and thermal radiation and suppression of fires due to the impact on the hearth work agent (RU 2035587, class. And 62 With 3/00, publ. 20.05.1999).
Having certain advantages over analogues, this method has obvious and significant disadvantages, which are its principal technical scheme impacts on the fire and clupeidae impacts are not carried out, and the suppression of inflammation is produced when already significantly developed fire, which deprives the way required reliability and efficiency of protection of the protected area and array.
As the closest analogue to the present invention is adopted a method of fire prevention and extinguishing of forest fires, which consists in the delineation of the protected area of forest land and the placing on the most fire stations agnadema installation gidrostekloizol material with bringing her to the emergency operating state, tracking the status of the array and suppression of fires by exposure to liquid (WO 96/05887, class. And 62 With 3/02, publ. 29.02.1966).
The technical task and technological results of the present invention is to increase the reliability of protection to the protected area, prevention of proliferation of fires; more reliable and efficient extinguishing of fires occurred and fires a protected forest area.
The technical task and technological results in the invention are achieved by a method for fire prevention and extinguishing of forest fires, which consists in the fact that the protected area UCAS gidrostekloizol material, lead the installation of duty in working condition, monitor the status of the array and suppress fires by exposure to a liquid, characterized in that the contours and boundaries, given the lines at area fire stations are placed flat elongated coaxial sleeve and the flow of the liquid initially carried out by the Central cavity coaxial sleeves, and gidrostekloizol material placed in the annular gap coaxial sleeves, and the last made with the possibility of damage to thermal radiation from the fire with the ejection volume of the liquid under pressure to the source of fire, suppression and prevention of fires on the protected site. In addition, gidrostekloizol material has the property to accumulate a significant amount of agnadema liquid and keep the liquid. As well as the protection of structures in hazard area carried out at the expense of the protection of the walls and structures of the imposition of such sleeves, made in the form of a flat tape. At the same time as gidrostekloizol material take polyelectrolyte hydrogel with a degree of swelling of about 2104 when the intake volume of the working of the liquids is a, and part of the wall of the sleeve is performed with filter inserts for intake of ambient humidity.
Method for fire prevention and extinguishing of forest fires is disclosed below in an example of implementation with reference to the drawings, where:
in Fig.1 shows the structure of an elastic provopoulos sleeve in a fully-loaded;
in Fig.2 shows the structure of multi-layered sleeves, designed for complex fire situations;
in Fig.3 shows the protection part of the buildings;
in Fig.4 - the same, in Fig.3, but a fragment of buildings;
in Fig.5 shows a flat elastic sleeve with his stock on the reel or spool for the facilities they use and transportation.
The design of flat elongated coaxial sleeve 1 (Fig.3, Fig.1 - loaded) has an external shell (1) and at least one Central centrally located elongated elastic sleeve 2 (Fig.2, figs.1), between which there is an annular gap 3, which is filled by a material having the property to accumulate a significant amount (volume) agnadema fluid (fluid in the form of water or water-based) and keep the liquid in its structure. As such a material preferably is th 2104), this material is enclosed in polyamideimide film, reinforced by a grid of fullerite (or pyrocarbon, or a mixture of fullerite and pyrocarbon).
Specified the sleeve 1 can be made multi-layered and include several similar sleeve 4 (Fig.2) posted one in the other with the walls of the sleeves should be carried out with filter inserts 5 for filtering the liquid from the volume in the volume between the gaps 6, but also to be able fence moisture from the soil and vegetation and the ground surface, and also for the discharge of the liquids from the sleeve when it is overheating or compression of the walls.
Technologically elongated sleeve is placed on the reel in the form of a flat belt 7 (Fig.5), the coil 8 may be placed on any vehicle that gives the mobility method.
If necessary, the protection of buildings or structures 9 (Fig.3, 4) sleeve design protects applying it in the form of a tape 10 on a large area wall, structure, or part of the tape 11 on the protected fragment 12 buildings, if it is subject to protection in the territory of the protected forest.
The protected area of woodland framing and most of the fire stations is accumulating material, the liquid serves on the Central cavity 2, and by layering (Fig.2) cavities gaps 6; saturate the material in the gap 3 of this agnadema liquid. When there is inflammation of the wall of the sleeve 1 is damaged by thermal effects and the emission of the hearth fire, and part of the liquid from the volume of the gap 3, gap 6 under pressure (due to its accumulation under pressure and additional heat flashpoint) is thrown on the fire, suppressing the fire and preventing the spread of fire in the protected area of the array and on the protected structures on the territory of the protected forest.
When the design of the sleeves in the form of a multilayer (Fig.2) it metaresources supply increases sharply, because when spending agnadema fluid in one annular gap sleeve does not lose its technical functions, including fire following stocks agnadema fluid in the following clearances 6.
Thus, the method of fire prevention and extinguishing of forest fires, extinguishing and preventing fires in buildings, constructions has reliability warnings and efficient extinguishing of fires, is a versatile, mobile and multi-purpose technical onepad is osenia forest fires, namely, that the protected area forest framing and the most flammable parts are placed ownerdallas installation gidrostekloizol material, lead the installation of duty in working condition, monitor the status of the array and suppress fires by exposure to a liquid, characterized in that the contours and boundaries, given the lines at area fire stations are placed flat elongated coaxial sleeve and the flow of the liquid initially carried out by the Central cavity coaxial sleeves, and gidrostekloizol material placed in the annular gap coaxial sleeves, and the last made with the possibility of damage to thermal radiation from the fire with the ejection volume of the liquid under pressure to the source of fire, suppression and prevention of fires on the protected site.
