Abstract
The utility model discloses a fire prevention ware disappears based on gas generator drive ordinary pressure liquid fire extinguishing agent, liquid storage pot (2) of extinguishing medium (3) and controller (7) that link to each other with the sensor are equipped with including inside, the top of liquid storage pot (2) is equipped with nozzle (1), be provided with piston (4) in liquid storage pot (2), fill in liquid storage pot (2) on piston (4) upper portion extinguishing medium (3), install in liquid storage pot (2) of piston (4) lower part gas generator (5), gas generator (5) are connected with controller (7) that set up outside liquid storage pot (2) through control pencil (6). The beneficial effect of the utility model: simplifying the fire extinguishing system structure, subtracting the light system total weight, reduce cost reduces installation space, and is easy to assemble.
Description
Technical field
This utility model relates to a kind of extinguishing device in fire control technology field, particularly to a kind of fire extinguisher driving normal-pressure liquid extinguishing chemical based on gas generator.
Background technology
At present, the fire fighting extinguisher of normal-pressure liquid extinguishing medium is generally adopted gases at high pressure (such as nitrogen etc.) driving.High pressure gas storage exists in gas cylinder, occur when fire-fighting controller detects the condition of a fire, and confirm that the condition of a fire occurs by certain logical judgment, namely the electromagnetic valve on gas cylinder is opened, gases at high pressure enter extinguishing medium by pipeline and store in tank body, promote piston, make extinguishing medium eject from storage tank body, cover burning things which may cause a fire disaster, so as to extinguish.
Existence due to gas cylinder so that this system exists security risk in some cases, as being subject to shock, significantly variations in temperature, the aging corrosion of gas cylinder etc..Meanwhile, gas cylinder there is also the risk of gas leakage, after causing system start-up, it does not have enough power is pushed to extinguishing medium injection.
Utility model content
For the defect existed in the fire fighting extinguisher of existing liquid fire extinguishing medicament, this utility model provides a kind of fire extinguisher driving normal-pressure liquid extinguishing chemical based on gas generator.
To achieve these goals, the measure that this utility model is taked:
A kind of fire extinguisher driving normal-pressure liquid extinguishing chemical based on gas generator, including internal equipped with the fluid reservoir of extinguishing medium with the controller that is connected with sensor, the top of fluid reservoir is provided with nozzle, piston it is provided with in fluid reservoir, extinguishing medium is filled in the fluid reservoir of upper piston area, being provided with gas generator in the fluid reservoir of piston lower portion, gas generator is connected with the controller being arranged on outside fluid reservoir by controlling wire harness；
Described extinguishing medium is liquid fire extinguishing medicament；
Described liquid fire extinguishing medicament is fire foam or halon extinguishing agent or clear water extinguishing chemical.
The beneficial effects of the utility model: use gas generation module to replace gas cylinder device, avoid gas cylinder to be subject to clashing into after-explosion, when ambient temperature significantly changes, stored gas atmosphere significantly changes the gas cylinder explosion caused, and the add-on security risk such as the explosion that causes of the aging corrosion of gas cylinder；Greatly simplifie fire-fighting system structure, alleviate system gross weight, reduce cost, decrease installing space, convenient installation.
Accompanying drawing explanation
Fig. 1 structural representation of the present utility model.
Detailed description of the invention
For overcoming the defect existed in the defect existed in the fire fighting extinguisher of existing liquid fire extinguishing medicament, design a kind of fire extinguisher (such as Fig. 1) driving normal-pressure liquid extinguishing chemical based on gas generator, including internal equipped with the fluid reservoir 2 of extinguishing medium 3 with the controller 7 that is connected with sensor, the top of fluid reservoir 2 is provided with nozzle 1, piston 4 it is provided with in fluid reservoir 2, extinguishing medium 3 is filled in the fluid reservoir 2 on piston 4 top, in the fluid reservoir 2 of piston 4 bottom, gas generator 5 is installed, gas generator 5 is connected with the controller 7 being arranged on outside fluid reservoir 2 by controlling wire harness 6；Described extinguishing medium 3 is liquid fire extinguishing medicament；Described liquid fire extinguishing medicament is fire foam or halon extinguishing agent or clear water extinguishing chemical.
Operation principle of the present utility model: install gas generator 5 in the cylinder, when there being the condition of a fire to occur, controller 7 receives sensor (warming, cigarette sense, and/or other condition of a fire detection sensor) fire signal that detects, by certain logical judgment and when confirming that the condition of a fire occurs, trigger signal by controlling wire harness 6 to gas generator 5 output, start gas generator 5 and produce gases at high pressure；Gases at high pressure promote piston 4 to move upward, and make extinguishing medium 3 be transported to desired position by nozzle/valve 1, cover burning things which may cause a fire disaster, so as to extinguish.
The beneficial effects of the utility model: use gas generation module to replace gas cylinder device, avoid gas cylinder to be subject to clashing into after-explosion, when ambient temperature significantly changes, stored gas atmosphere significantly changes the gas cylinder explosion caused, and the add-on security risk such as the explosion that causes of the aging corrosion of gas cylinder；Greatly simplifie fire-fighting system structure, alleviate system gross weight, reduce cost, decrease installing space, convenient installation.
The simple change of those ordinary skill in the art and replacement are all within protection domain of the present utility model.
