Description
Technical field
The present invention relates to fire control technology fields, and in particular to a kind of spherical shape extinguishing device.
Background technology
Spherical extinguishing device is suitable for the inaccessible fire situation of personnel, has the characteristics that the fire extinguishing of simple safety.At present
Though existing spherical shape extinguishing device type is more, it is primarily present following problem：
(1) spherical extinguishing device generally use is common dry powder fire extinguishing agent, and grain size is larger, and (average grain diameter 30-50 is micro-
Rice), dispersivity is poor (easily falling after injection), and jet velocity is slow, therefore the entire scene of a fire of moment covering is difficult to realize after explosion, to combustion
Burn the covering of object surface discontinuously, fire extinguishing effectiveness is not high.
(2) jet port of spherical extinguishing device is mostly a jet port, this causes dry powder fire extinguishing agent can only be along single
It is sprayed in direction.And the position and state after extinguishing device is thrown in the scene of a fire are difficult fixation, once the direction of single jet port
It is unable to face ignition point, or even backwards to ignition point, fire-fighting efficiency will substantially reduce.
(3) from opening in terms of quick-fried mode, most of spherical shape extinguishing device blows shell using the dangerous material such as detonator, explosive device
Body, to make firing-fighting medium in scene of a fire disperse.It is this open quick-fried mode be likely in closed environment to ambient enviroment and personnel with
It damages and injures, there are larger security risks, are also not easy to store and transport；Also some opening using compression gas cylinder
Quick-fried mode, this so that extinguishing device is complicated, of high cost, and weight is big, and air valve is must be turned on before use, and being delayed, it is quick-fried to open, and must
The air pressure of palpus periodic detection gas cylinder.
(4) triggering mode of domestic outer spherical extinguishing device is divided into active and two kinds of passive type at present.Actively triggering side
Formula uses Time-delayed trigger principle, before throwing, the safety device of initiation system is released, control device for detonation of electric starts timing, timing
Length generally will be determined accordingly in design, is terminated after-explosion in timing and is put out a fire.Passive triggering mode is tactile using hitting
Principle is sent out, after extinguishing device reaches drop point, triggering explosion is put out a fire.It either actively or passively triggers, in practice
In all Shortcomings.Using Time-delayed trigger, extinguishing effect is extremely unstable, corresponding to be delayed if quenching distance changes
Time cannot flexibly change therewith, and extinguishing device, which can shift to an earlier date or lag behind best blast area, sheds extinguishing chemical, and extinguishing chemical is not
It can effectively be covered.It is triggered using hitting, extinguishing device could detonate after reaching drop point, and extinguishing chemical sheds the region of covering
It is limited to the influence of the factors such as landform and explosion environment, extremely limited a piece of scene of a fire region can only be acted on.
