The external dioxide bottle in top is connected with nitrogen cylinder, forms the channel for pinpointing downward spray fire extinguishing agent, smoke alarm
It is fire alarm control unit advance signal device.It is theed improvement is that：Described packaging box cavity one end, which is removed, is configured with fire prison
Examining system is provided with fire alarm system and fire extinguishing disposal system, and fire hazard monitoring system therein is by smoke alarm, camera shooting
Monitor and temperature monitor form the stereoscopic monitoring system of three kinds of signal sources.The emergency light and acousto-optic of fire alarm system configuration
Alarm is directly controlled by smoke alarm, when fire occurs there is acousto-optic to synchronize warning function.Disposal system put out a fire by putting out a fire
Nozzle, dioxide bottle, nitrogen cylinder, exhaust fan, manual-operated emergent switch, mechanical shutter, fire alarm control unit, flow news
Number device, PCS controllers composition, the linkage fire-fighting system both can full-automatic fire-extinguishing, remote control fire extinguishing, can also control and go out manually
Fire.
Scheme as a further improvement, the smoke alarm, exhaust fan, manual-operated emergent switch, emergency light, acousto-optic report
Alert device, camera monitor, temperature monitor, mechanical shutter, flow signalling device, PCS controllers are unified by fire alarming and controlling
Device centralized Control is linked by preset function sequence during operation.
When scheme as a further improvement, the smoke alarm and temperature monitor all reach setting threshold values, fire
Alarm controller just confirms that fire exists, and synchronizes the instruction for sending out and closing exhaust fan, mechanical shutter, starts PCS controls immediately
Device processed cuts off main circuit, also synchronous to open the valve of dioxide bottle and nitrogen cylinder implementation extinguishing operation in fire extinguishing disposal system.
Scheme as a further improvement, the machinery shutter are mounted on the upside of one end door of energy storage container, exhaust fan
Then it is placed in the another side of container.
Scheme as a further improvement, the smoke alarm, exhaust fan, manual-operated emergent switch, emergency light, acousto-optic report
Alert device, camera monitor, temperature monitor, mechanical shutter, fire alarm control unit, flow signalling device and PCS controllers are matched
The power supply put is relative to main circuit independence.
Compared with prior art, the present invention it has the positive effect that：
1st, energy storage container linkage fire-fighting system is collectively constituted by fire hazard monitoring system, fire alarm system and fire disposal system
System, reasonable, technologically advanced, the mutually coordinated property of system configuration are good；
2nd, system is equipped with camera monitor, and when smoke alarm and temperature monitor all reach setting threshold values, fire report
Alert controller, which is just sent out, occurs alarm of fire in container, this multifactor control model is highly reliable, it is ensured that the fire sent out
Information is accurate；
3rd, critical piece mutually links in system, accomplishes pointing fire-extinguishing, in time fire extinguishing, high-effect fire-extinguishing conscientiously；
4th, system can also make remote control fire extinguishing by camera monitor, can also use hand except having automatic fire-extinguishing function
Dynamic emergency button controls fire extinguishing nearby.
Description of the drawings
Fig. 1 is plan structure diagrammatic cross-section of the present invention.
Fig. 2 is Fig. 1 left view structural representations.
Fig. 3 is principle of the invention figure.
Specific embodiment
Below according to attached drawing and in conjunction with the embodiments, the invention will be further described.It needs to state, it is described herein
Embodiment is intended merely to explain the present invention, is not to limit the present invention.
Energy storage container linkage fire-fighting system shown in FIG. 1 is configured in solar power station, it is that carrier disposes with container 1
Accumulator group, the container 1 of the present embodiment application is a kind of TEU (Twenty-foot Equivalent Unit), in 1 inner cavity of container phase along the length direction between two parties
Between arrangement fire extinguishing sprayer 3 and smoke alarm 4.Nozzle fire extinguishing sprayer 3 directed downwardly by pipeline and the top of container 1 it is external two
Carbonoxide gas cylinder 5 is connected with nitrogen cylinder 6, forms the channel for pinpointing downward spray fire extinguishing agent.The smog adjacent with fire extinguishing sprayer 3
Alarm 4 is 14 advance signal device of fire alarm control unit, and the smoke alarm 4 of scattered resettlement is believed convenient for capturing fire in time
Breath.The present invention is removed is configured with fire hazard monitoring system in 1 inner cavity one end of container, is provided with fire alarm system and fire extinguishing is disposed
System.Fire hazard monitoring system therein forms three kinds of signal sources by smoke alarm 4, camera monitor 11 and temperature monitor 12
Stereoscopic monitoring system, once 1 built-in device of container has a fire behavior, the smoke alarm 4 in fire hazard monitoring system captures first
Fire behavior information, then temperature monitor 12 alarm when being rapidly heated.The present invention generates erroneous judgement in order to prevent, sets smog alarm
When device 4 and temperature monitor 12 all reach setting threshold values, fire alarm control unit 14, which just confirms, occurs fire in container 1.And
Send out alarm of fire.It is this highly reliable by dual factors control model, it is ensured that the fire information sent out is accurate.In addition, this
Invention can also make that fire extinguishing is remotely monitored and controlled by camera monitor 11.The fire alarm emergency light 9 and sound-light alarm
Device 10 is directly controlled by smoke alarm 4, and acousto-optic synchronizes alarm when fire occurs, this function can improve warning effect.It is described to go out
Fiery disposal system is by fire extinguishing sprayer 2, dioxide bottle 5, nitrogen cylinder 6, exhaust fan 7, manual-operated emergent switch 8, mechanical shutter
13rd, fire alarm control unit 14, flow signalling device 15, PCS controllers 16 form.Mechanical shutter 13 is placed in above structure
On Fig. 1 offside doors, exhaust fan 7 is then on Fig. 1 offside doors.In order to realize fire-fighting link, the smog alarm in the present invention
Device 4, exhaust fan 7, manual-operated emergent switch 8, emergency light 9, audible-visual annunciator 10, camera monitor 11, temperature monitor 12, machinery
Shutter 13, flow signalling device 15 and PCS controllers 16 are unified by 14 unified centralized Control of fire alarm control unit, and will be upper
The power supply of each component configuration is stated relative to main circuit independence.
Energy storage container linkage fire-fighting system of the present invention is standby under normal circumstances, once inside container 1
Fire behavior occurs, when only smoke alarm 4 and temperature monitor 12 all reach setting threshold values, fire alarm control unit 14 just confirms
Fire exists, and synchronizes the instruction for sending out and closing exhaust fan 7, mechanical shutter 13, starts PCS controllers 16 immediately and cuts off main electricity
Road, it is also synchronous to open dioxide bottle 5 and the implementation extinguishing operation of nitrogen cylinder 6 in fire extinguishing disposal system.If above-mentioned control failure
Living, the present invention can also be switched 8 controls nearby by manual-operated emergent and be put out a fire.Each functional component mutually links in the present invention, conscientiously
Accomplish pointing fire-extinguishing, in time fire extinguishing, high-effect fire-extinguishing.
