Not stay the cryogenic liquid of any vestige be extinguishing chemical because the utility model is with after nontoxic, harmless, the ejection, thereby it compared with prior art has following advantage in fire extinguishing procedure: 1, can make all article that leave the scene of fire in all not suffer any pollution and damage because of the fire extinguishing operation; 2, can effectively avoid environmental pollution.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
As seen from the figure, the utility model comprises automobile 1, basin 2 and injection apparatus.Its design feature is:
Basin is made of the tank body that the cryogenic liquid jar both had been exclusively used in the splendid attire cryogenic liquid, and this jar is mainly used in space industry in the prior art.This basin is fixedly connected on automobile, and liquid level gauge 8, Pressure gauge 11, safety valve 10 and charging control assembly 9 and emptying control assembly 12 are installed respectively on its tank body.Wherein, the charging control assembly is made up of feed pipe and on-off control valve door thereof; The emptying control assembly then is made up of blow-down pipe and on-off control valve door thereof respectively.During use, basin fills cryogenic liquid in the chamber, and this liquid can be respectively liquid nitrogen or liquid argon or liquid carbon dioxide.
Injection apparatus mainly is made up of act arm 19, act arm bearing 18, evaporimeter 6, cryogenic liquid pump 13, spray gun 15.Wherein:
Lower end and the automobile of lifting arm bearing 18 are fixedly connected, and the upper end had both illustrated right-hand member with act arm 19 rear ends and has been hinged.
During assembling, injection line along lift the arm bearing and lift arm adhere to the location after, its other end both be not positioned at the joining end of described liquid pump to be lifted the arm front end and had both illustrated the left end end, this end connects spray gun 15.
In the present embodiment, above-mentioned act arm drive unit is made up of hydraulic jack 20, hydraulic motor and operation control assembly thereof.Wherein, motor and control member made and all dress up one with automobile; Hydraulic jack is arranged on to be lifted between arm and the act arm bearing.Should illustrate that the version of above-mentioned act arm drive unit is not unique.For example, it can also be made of or the like the hoisting mechanism that steel wire rope, reel, decelerator, power set, pulley etc. are formed.Because this class technology is very familiar to those of ordinary skills, so be not repeated at this.
In order to make the utility model obtain better result of use, in the present embodiment, it also is provided with the automatic monitoring system system that can monitor ignition point automatically.This system is made up of The Cloud Terrace 21, video camera 22, gps system 23, DVD device 24 respectively.Wherein, The Cloud Terrace, video camera are arranged on lifts the arm leading section, and it is indoor that gps system and DVD device then are arranged on car steering.Because this technology is known by the public, so no longer use installation and method of operating carefully to state one by one to it at this.Certainly, automatic monitoring system system is not set in actual production, the utility model also can use.
The utility model uses method of operating to be:
After receiving fire alarm, in driving towards the way of scene of fire, should open valve 27, make the interior cryogenic liquid extinguishing chemical of basin enter evaporimeter, make it evaporation, thereby the pressure gas is provided in basin; Enter after the fire spot, start cryogenic liquid pump, and open valve 4 and valve 14, then, adjust and lift the arm position, extinguishing chemical is sprayed onto the target location, both can reach the fire extinguishing purpose.
