Abstract
The utility model relates to a fuel gas fire-extinguishing gun, which can transmit a fire-extinguishing bullet from a gun pipe to a high or a far fire area in which firefighters are difficult to approach by making use of the expansion work of fuel gas combustion. A fire-extinguishing bullet filling opening 1 of the utility model is positioned at the conjoint place of a combustion chamber 7 and a gun pipe 4, and the bullet filling opening 1 can be opened or closed. The combustion chamber 7 is communicated with a fuel nozzle 10. The flammable premix gas is injected into the combustion chamber 7 by the fuel nozzle 10, and the flammable premix gas can work in an expansion mode after the flammable premix gas is ignited to be combusted; thereby, the fire-extinguishing bullet is pushed to transmit from the gun pipe to the fire area, and the fire is extinguished.
Description
The utility model is about a kind of fire plant, belongs to fire-fighting domain.
Along with the development of society, the skyscraper in the city is more and more intensive and highly more and more higher, in case the breaking out of fire at the middle and upper levels of these buildings then needs to use the fire-fighting equipment with high impelling ability; The use of the gas in the modern life, liquid fuel and ignition control compound is more and more general, in case the production of these article, storage house breaking out of fire, the fire fighter is not easy approaching, need to use can telekinesy the fire-fighting instrument.The patent No. is the fire plant that 942001788 Chinese patent discloses a kind of rocket fire-extinguishing bullet, though this device operating distance is far away, can fly to reach far beyond high zone, it belongs to priming system, all have higher requirements for storing, transport, launching, price is also comparatively expensive; The patent No. is the fire plant that 95201493.9 Chinese patent discloses the air pressure fire monitor, the characteristics that this device has is cheap, store safety, but tranmitting frequency is low, operating distance is shorter.
Task of the present utility model just provides the fire plant that a kind of price is lower, storage is safe, simple to operate, tranmitting frequency is high, operating distance is far away.
The utility model is achieved in that
The combustion gas fire monitor is by combustion chamber, gun tube, fire-fighting shell filler, and fuel injection system, igniter etc. are partly formed.The combustion chamber is the space of flammable premixed gas body burning; Gun tube communicates with the combustion chamber, when the combustion gas expansion is done work and acted on the fire-fighting shell, is used for leading to the fire-fighting shell; Fire-fighting shell filler is used for the fire-fighting shell is packed in the gun tube, as required opening and closing and can sealing; Fuel injection system is used for injecting gas fuel or steam fog liquid fuel in the combustion chamber; Igniter is used to light gaseous fuel or the steam fog liquid fuel that injects in the combustion chamber.
The course of work of the present utility model is as follows:
Open fire-fighting shell filler, in the fire-fighting shell pack into gun tube from fire-fighting shell filler, close fire-fighting shell filler, fuel injection system is injecting gas fuel or steam fog liquid fuel in the combustion chamber, igniter is lighted combustible gas in the combustion chamber, and fuel gas buring expansion acting also acts on the fire-fighting shell, and the fire-fighting shell flies to the scene of a fire under the guiding of gun tube, shed extinguishing chemical, realize fire extinguishing.
Provide an embodiment of the present utility model below, and in conjunction with the accompanying drawings embodiment is described in detail.
Accompanying drawing is the structure chart of present embodiment.
In the accompanying drawing, fire-fighting shell filler 1 is positioned at combustion chamber 7 and gun tube 4 junctions, can open or close; Open fire-fighting shell filler 1, fire-fighting shell 3 can be packed in the gun tube 4, a shell spacing ring 2 is arranged at fire-fighting shell 3 bottoms, and shell spacing ring 2 is used for limiting the position of fire-fighting shell 3 in gun tube 4, and can separate with fire-fighting shell 3 during in fire-fighting shell 3 in the fuel gas buring expansion; Combustion chamber 7 is spaces of flammable premixed gas burning; Fuel tank 13 is used for storaging liquid fuel, and fuel tap 11 and oil pump 12 cooperate the flows that are used for controlling the fuel injection jointly; Fuel nozzle 10 is connected with combustion chamber 7, and can carry out steam fogization to liquid fuel; An air valve 9 is arranged on the fuel nozzle 10, be used for controlling the injection of flammable premixed gas in combustion chamber 7; Air storage tank 14 is used for storing compressed air and is connected with fuel nozzle 10, and air compressor 15 is injecting compressed air in air storage tank 14; Electric igniter 8 is used for the flammable premixed gas in the ignition combustion chamber 7.After all burnt and fire-fighting shell 3 have been launched, refill air in order to discharge the flue gas after 7 internal combustion of combustion chamber as early as possible and to make in the combustion chamber 7, on combustion chamber 7, leave suction (row) gas port 6 that can open or close, can have scavenger fan 5 on suction (row) gas port 6.
The process that the combustion gas fire monitor is implemented fire extinguishing is such:
Open fire-fighting shell filler 1, fire-fighting shell 3 is packed in the gun tube 4, close fire-fighting shell filler 1, close suction (row) gas port 6, at this moment, combustion chamber 7 is in the state of being hedged off from the outer world; Control fuel tap 11, oil pump 12 and air valve 9, in combustion chamber 7, inject flammable premixed gas by fuel nozzle 10, and make fuel and airborne oxygen reach suitable ratio, discharge the spark that enough energy are arranged by the flammable premixed gas of electric igniter 8 in combustion chamber 7, light flammable premixed gas, burning was finished in very short time, be full of high-temperature high-pressure fuel gas in the combustion chamber 7, gas pressure is pretended and is used for fire-fighting shell 3 bottoms, make to be connected destroyedly between fire-fighting shell 3 and the shell spacing ring 2, fire-fighting shell 3 is quickening in gun tube 4 under the effect of combustion gas pressure, until the gun tube 4 that flies out, fly to Huo Qu, throw in extinguishing chemical; Simultaneously, open suction and exhaust ports 6, venting combustion chamber 7 gas fume after burning, and make combustion chamber 7 refill air.Repeat said process, just can realize high-frequency, the district that warms oneself in front of a fire launches extinguishing cannonball at a distance.
Claims (2)
1. combustion gas fire monitor is characterized in that: fire-fighting shell filler 1 is positioned at combustion chamber 7 and gun tube 4 junctions, can open or close; Fuel nozzle 10 is connected with combustion chamber 7; Igniter 8 is positioned on 7 edges, combustion chamber.
2. combustion gas fire monitor according to claim 1 is characterized in that: the fuel that fuel nozzle 10 injects in combustion chamber 7 is flammable premixed gas;
