Specific implementation mode
Reach the technological means and effect that predetermined purpose is taken for the utility model is expanded on further, below in conjunction with attached drawing
And embodiment, to specific embodiment of the present utility model, structure feature and its effect, detailed description are as follows.
Referring to Figures 1 and 2, present embodiment discloses a kind of non-reservoir pressure duct type dry powder extinguishing installations 26, including tank body, production
Gas construction package, ABC ultra-fine dry powders 9, pneumatic control component, pipeline and nozzle 28, ABC ultra-fine dry powders 9 are arranged in tank body, production
Gas construction package includes gas production charge column and ignition powder, and the gas production charge column and ignition powder are fixedly connected with tank body.Aerogenesis component acts on
When, it generates bulk gas and breaks through the aluminium baffle above tank body, while by extinguishing chemical in gas when gas reaches certain pressure
Drive lower ejection tank body.
In the present embodiment, connecting seat 3 is connection dry powder output channel.Grate 1 mainly reaches one in gas flow
A grade medicine plate is broken through when quantitative, then sprays extinguishing chemical.Pipe installing exports carrier on connecting seat 3, for extinguishing chemical.Washer 2
It mainly seals, because ultra-fine dry powder density is especially small, prevents dry powder from leaking out.
In the present embodiment, the effect of socket 5 is connection external power supply.The main function of valve body 6 is by other structures packet
The effect covered.Initiator 7 is primarily used to start aerogenesis component.Also, as shown in Figure 1, cover board 4, socket 5,6 preferred spiral shell of valve body
Line connects.
Tank body ensure that extinguishing device 26 can be conveniently mounted to vehicle suitable position, be not take up in enging cabin 24 empty
Between.
ABC ultra-fine dry powders 9 are delivered to enging cabin 24 by metallic conduit 25 and nozzle 28, and nozzle 28 can be arbitrarily placed on
Near the device location that fire easily occurs in engine, the metallic conduit 25 of the present embodiment needs compression resistance strong, and metallic conduit 25 can
It is close to 24 wall of enging cabin arrangement, realization does not influence the maintenance of vehicle usually to greatest extent.
The aerogenesis construction package structure of the present embodiment ensure that non-reservoir pressure and the sustained release injection of extinguishing device 26, ensure that tank
Internal dry powder can be transported to by conduit assembly in enging cabin 24 under the effect of enough, safe, long-acting gaseous-pressure, and
It ensure that dry powder impact force is big, atomization is abundant, the efficient feature of fire extinguishing effectiveness.
The pneumatic control component of the present embodiment, it is preferred to use 2 are distributed in enging cabin 24 fire position easily occurs
Fire detector thermoswitch 27, for detecting temperature in enging cabin 24 and ensureing to be closed connection automatically when generation fire in cabin
Power supply simultaneously starts extinguishing device 26.The manual alarm switch of pneumatic control component is conveniently operated mounted on 23 driver and conductor of cockpit
Position, connect with extinguishing device 26 by conducting wire, starting switch pressed when driver has found fire behavior, start extinguishing device
26.Pneumatic control component energy storage power supply ensures, when vehicle power supply can not provide power service in 2115 days, to can guarantee vehicle-mounted non-
Reservoir pressure duct type dry powder extinguishing installation 26 works normally.
The energy-storage battery of the present embodiment is connect with pneumatic control component.When vehicle power supply 21 does not have electricity output, energy storage electricity
Pond is activated automatically, output current.The energy-storage battery of the present embodiment is electric signal starting pinciple, is not acted on usually.When not vehicle-mounted
In the case of power supply 21, energy-storage battery is activated by power-off signal, is switched automatic be closed and is generated electric current.
When driver manually has found fire hazard, can the safety device of cancel switch connect vehicle power supply by lower switch
21 with the start-up circuit of extinguishing device 26, realize the function of manually booting.
When temperature steeply rises to 160 DEG C or more in enging cabin 24, the contact closure of temperature switch, vehicle power supply 21
Start extinguishing device 26 by its contact and spray dry powder at jet pipe by metallic conduit 25 in 5 seconds, what is gushed out is ultra-fine
Dry powder one is directly impact burning things which may cause a fire disaster second is that entire enging cabin 24 is spread in, to achieve the purpose that prevention and stamp out a fire.
If idle in vehicle power supply 21（Such as storage battery out of power）, the automatic charging energy storage in pneumatic control component
Power supply is acted on instead of storage battery（It can keep 15 days）, when fire temperature, which occurs, for enging cabin 24 steeply rises to 160 DEG C or more, temperature
The contact closure of switch is spent, accumulation power supply starts extinguishing device 26 by its contact, to achieve the purpose that stamp out a fire.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard
To belong to the scope of protection of the utility model.
