The paper shell can avoid the fragment flying everywhere. The dry powder fire extinguishing agent has automatic damp prevention after applying with the powder with the ultra-fine grain size and ultra-excellent performance, which strengthens the fire extinguishing ability by times.

Description

Desk-top super-sonic dry-chemical fire extinguisher
Technical field
The utility model relates to a kind of fire-fighting equipment, particularly a kind of desk-top super-sonic dry-chemical fire extinguisher.
Background technology
Circuit board and battery case are equipped with in base, the side of Chinese patent CN2054340U super-sonic dry-chemical automatic fire extinguishing technology device, cause initiator in the metal porous pipe by thermistor.A branch of this super-sonic dry-chemical automatic fire extinguishing technology " fixed super-sonic dry-chemical automatic fire extinguishing system " development is very fast, under the guidance of national correlation department, helping, its technology content, the market share and social benefit are all occupied corresponding status and by social validation.The weak point that this extinguishing device exists is that initiator and device are connected as a single entity, and transports, storage cost is very high.
Summary of the invention
The purpose of this utility model is to take all factors into consideration its technical deficiency on the basis of existing super-sonic dry-chemical fire extinguisher, satisfy the specification requirement of national regulation, design that a kind of thermal conduction effect is stable, volume is little, storage, transportation safety, supersonic speed eruption fire-fighting powder time lengthening, the desk-top super-sonic dry-chemical fire extinguisher that the harm reduction of taking precautions against natural calamities is effective.
The technical scheme that its technical problem that solves the utility model adopts is as follows:
This desk-top super-sonic dry-chemical fire extinguisher, form by top cover, shell, guard ring, antipriming pipe, antipriming pipe upper plug head, antipriming pipe lower end cap, bottom, powder extinguishing agent and temperature sensing cable, it is characterized in that the external two core digital-code type temperature sensing cables of extinguishing device, initiator is arranged in the antipriming pipe, this initiator is made up of main initiator and secondary initiator, initiator and antipriming pipe upper plug head connect as one, antipriming pipe is the macromolecule material moulding, plastic packaging has two leads in the antipriming pipe upper plug head, passes guard ring and is connected with main initiator and temperature sensing cable; The antipriming pipe two ends are fixed by guard ring and antipriming pipe lower end cap.In order to prevent that the extinguishing device object from flying to overflow, housing of the present utility model adopts paper material to make, the fire-fighting powder that the powder extinguishing agent in its device adopts ultra-fine grain diameter, superperformance proportioning to form.
Architectural feature of the present utility model and operation principle are as follows:
This desk-top super-sonic dry-chemical fire extinguisher comprises the detection assembly of heat-sensitive cable formula, detachable compound initiator assemblies, antipriming pipe, powder extinguishing agent and five parts of assembly assembly; described heat-sensitive cable claims linear temperature sensitive cable again; by two elastic wires, the coated temperature-sensitive insulating materials mirror symmetrical molding of difference; the wrapped then plastic sheath that adapts to installation environment that adds is with addition of the usefulness of single core copper cash as ground protection.Under the normal monitoring state, insulating resistance value can pass through small standby current near infinitely great in the cable between the guiding principle silk.Around cable or its or institute's contact material rise in a certain surface temperature, when reaching rated function temperature, temperature-sensitive insulating materials fusing between steel wire, insulating resistance value transition, be close to short circuit, electric current increases suddenly, and its variation detects the back by fire alarm control unit and starts the work of extinguishing device initiator, the spray fire extinguishing agent fire extinguishing.The layout of heat-sensitive cable adopts straight line to draw in this extinguishing device, does not indicate part and adopts two core number or temperature sensing cables, plays the technique effect of one group of power supply and temperature detect switch (TDS).
To have the structure that can separate be one of important characteristic to initiator in the utility model, it makes extinguishing device thoroughly avoid unsafe factor in a large amount of storages, the transportation, saved in order to satisfy store in a large number, the costs that specific (special) requirements added of transportation.Adopt two initiator in this device, except that the conventional initiator that the connection heat-sensitive cable initiatively causes, also the cartridge bag of an additional passive initiation is as secondary initiator, igniting once more in the HTHP high-speed fuel gas flow field that forms after the former works makes the solid propellant rocket of this extinguishing device have the technical benefits of lengthening working time.
The material of described antipriming pipe, in order to reduce manufacturing cost, adopt macromolecular material, be the progress of plastic processing on the one hand, the moulding compressive resistance improves, the 2nd, adopt add the solid propellant rocket that works long hours after, the peak value of overpressure of gas in the antipriming pipe has been descended, moment can not occur causing and cause because of the superpressure value is excessive that body breaks, the pulverizing situation.
Described powder extinguishing agent no longer is common powder extinguishing agent, but according to need and the ultra-fine grain diameter, overdominance of control proportioning can (as automatic protection against the tide etc.) special extinguishing agent.
Described assembly assembly, its guard ring will be clamped antipriming pipe, prevent that in gas flow field the phenomenon that the expansion with antipriming pipe causes its upper plug head to fly to escape occurs, this is structural one to change greatly, all will reach this specification requirement in the top of antipriming pipe, the design of bottom.The 6th technical characterictic is that shell has substituted flame-retardant foam with the paper material through flame treatment, not only makes device tall and straight, and intensity is easy to control, is convenient to tear into strips, do not have object to fly to overflow when importantly working and goes.
After the feature that has aspect above-mentioned six, this extinguishing device has following benefit:
1. effectively and economically improved the detection alarm precision.
2. improve extinguishing ability, reduced noise, do not flown the thing that escapes during work.
3. save manufacturing cost, alleviated weight.
