Description
Technical field
The invention belongs to extinguishing device fields, more particularly to a kind of automatic fire extinguisher based on Eco-drive.
Background technique
In recent years, with the support energetically that country develops new-energy automobile, electric car production and marketing quantity rapid growth is produced
Industry paces are constantly accelerated.At this stage, electric car is mainly using lithium ion battery as power battery, by the development of many years,
The safety of lithium-ion-power cell has been significantly improved, but under extreme conditions, and lithium battery still has burning, quick-fried
Fried risk.Country, place are by issuing every filespec, it is intended to further strengthen power battery fire protection requirement, ensure people
People's security of the lives and property.Automobile factory mainly guarantees the fire safety of battery by active safety and passive security at present.Actively
Safety is that the parameters such as voltage, electric current, the temperature for monitoring inside battery in real time by battery management system (BMS) are realized.Work as electricity
The parameters such as voltage, electric current, the temperature in pond exceed design value, and BMS sends relevant information to instrument, issues acousto-optic by instrument
Alarm, while being communicated with ground charging pile, entire car controller, by reducing power output, cutoff high, implement effective safety
Measure.Passive security is by installing additional device, it is ensured that when fire occurs for battery, carries out early warning, fire extinguishing to fire, prevents
Fire spreads to vehicle from battery.If extinguishing device can not put out a fire completely to battery, also to be reminded by warning device
Occupant flees from, delays the fire spread time with fire-retardant fireproof material.
Pure electric vehicle city bus power battery mainly uses middle part, rear portion floor lower section, the individually designed battery of vehicle rear
The arrangements such as cabin and vehicle floor lower section, top mixing.Regardless of which kind of arrangement power battery uses, occurring promptly
Fire behavior inside power battery cabin can not be observed directly when fire incident, in passenger compartment.If fire occurs for power battery cabin,
By the passenger compartment that ignites rapidly, threaten to passenger safety.Especially battery arrangement square vehicle under floor, city bus
Plate generally uses bamboo reinforcement plate, belongs to inflammable thing, after batteries caught fire, by quick igniting bamboo reinforcement plate, causes difficulty to occupant's escape.Cause
This, takes fire prevention measure appropriate, can effectively reduce injury of the fire to vehicle and personnel.
Extinguishing device generally used now mostly uses the mode for separating fire suppression bottle, passes through battery-driven solenoid valve control pair
Extinguishing device is opened and closed, and when vehicle is parked for a long time, system may be out of power.
Summary of the invention
In view of the above problems, the present invention is based on existing battery automatic fire extinguisher, provide a kind of new dynamic based on light
The automatic fire extinguisher of energy, is the extinguishing device of energy by photoelectricity, and the photocell of equipment is mounted on the shading in lithium battery box
Environment, when equipment kindling, flame provides energy, and driving equipment automatically turns on solenoid valve, to put out a fire.
To achieve the goals above, the present invention provides a kind of automatic fire extinguisher based on Eco-drive, including lithium battery box,
Fire suppression bottle, control circuit, photocell, gas/liquid spray valve；Gas/liquid spray valve connection gas/liquid transmission pipeline is located above lithium battery；Gas/
Liquid transmission pipeline connects fire suppression bottle；Control circuit controls the unlatching of the solenoid valve of fire suppression bottle；Photocell is installed in lithium battery box
Shading environment, when equipment kindling, flame supplies energy to photocell, and drive control circuit automatically turns on solenoid valve, from
And it puts out a fire.
It also has host power supply, alarm, temperature sensor and smoke sensor device；Host power supply can supply for each equipment
Electricity issues alarm signal when temperature sensor or smoke sensor device detect abnormal.
Its temperature sensor reaches a certain fixed value in temperature or the rate of climb is accelerated, then alarms.
Its smoke sensor device reaches a certain range alarm when environmental smoke value.
Fig. 1: for the installation site figure of the automatic fire extinguisher of the prior art；
Fig. 2: for the schematic diagram of the automatic fire extinguisher of the invention based on Eco-drive.
The on-vehicle battery extinguishing device of the automatic fire extinguisher of the prior art is installed on vehicle interior lithium electricity as shown in Figure 1:
Near the case of pond, including control cabinet, fire suppression bottle, injection valve, sensor, host power supply, transmission module；Sensor is temperature sensing
Device, smoke sensor device and optical sensor have injection valve on fire suppression bottle, and control cabinet connects each sensor and injection valve,
Transmission module transmits fire alarm, in order to timely alarm and evacuates passenger, and host power supply is the power supply of the equipment such as control cabinet.Wherein
Working principle are as follows: 1. temperature sensors, temperature reaches a certain fixed value or the rate of climb is accelerated, then it is assumed that alarm.It is common
It is set as, 5 °C of alarms of 60 °C of alarms or rising per second；2. smoke sensor device, when environmental smoke value reaches a certain range report
It is alert；3. optical sensor, the light of certain wavelength is measured, necessarily there is light generation in kindling when.On-vehicle battery extinguishing device is in work
When, need vehicle stopping still working, it is therefore desirable to power for a long time using Vehicular battery.
Above-mentioned automatic fire extinguisher is powered at each sensor and drive magnetic valve control to going out by host power supply
Fiery device is opened and closed, and when vehicle is parked for a long time, system may be out of power.
As shown in Figure 2: the automatic fire extinguisher of the invention based on Eco-drive includes lithium battery box, fire suppression bottle, control electricity
Road, photocell, gas/liquid spray valve；Gas/liquid spray valve connection gas/liquid transmission pipeline is located above lithium battery, and gas/liquid transmission pipeline connects
Fire suppression bottle is connect, control circuit controls the unlatching of the solenoid valve of fire suppression bottle, and photocell is installed on the shading environment in lithium battery box, when
When equipment is caught fire, flame supplies energy to photocell, and drive control circuit automatically turns on solenoid valve, to put out a fire.
It is contemplated that just in case going wrong there are photocell or when electricity shortage, may not opens solenoid valve, thus
Lead to not self-extinguishing, host power supply, alarm, temperature sensor and smoke sensor device can be further added by this basis；
Host power supply can power for each equipment, when temperature sensor or smoke sensor device detect abnormal, issue alarm signal.Temperature
Sensor reaches a certain fixed value in temperature or the rate of climb is accelerated, then alarms.Smoke sensor device is reached when environmental smoke value
It alarms to a certain range.
