Description
Technical field
The invention belongs to extinguishing device fields, more particularly to a kind of battery automatic fire extinguisher used on vehicle.
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.
Summary of the invention
In view of the above problems, providing a kind of battery automatic fire extinguisher the present invention is based on existing new energy vehicle.
It is an object of the present invention to temperature sensor measurement lithium battery temperature, around light sensor measurement lithium battery
Flame measures smog with smoke sensor device, according to three kinds of sensors as a result, judge whether to start solenoid valve, opens fire suppression bottle
In fire-suppressant gas spray.
To achieve the goals above, the present invention provides a kind of on-vehicle battery extinguishing devices, including battery self-extinguishing master
Control cabinet, fire suppression bottle, injection valve, sensor, host power supply, transmission module；The sensor includes temperature sensor, smog
Sensor and optical sensor；There is injection valve on fire suppression bottle；Control cabinet connects each sensor and injection valve；Transmission module
Transmit fire alarm；Host power supply is the power supply of the equipment such as control cabinet；Temperature sensor measurement lithium battery temperature reaches pre- in temperature
Definite value or its rate of climb are accelerated, then it is assumed that alarm；Smoke sensor device measures smog；Optical sensor measures one around lithium battery
The long flame of standing wave；Temperature sensor is started switch as smoke sensor device and optical sensor.
Preferably, the predetermined value of temperature sensor alarm is 60 °C.
Preferably, the rate of climb of temperature sensor alarm is 5 °C of rising per second.
Preferably, further include driver's cabin combined aural and visual alarm, be connected to the transmission module.
Preferably, injection valve connects fire-suppressant gas jet pipe, and extinguishing chemical is sprayed by fire-suppressant gas jet pipe, fire-suppressant gas
Jet pipe covers entire lithium battery box.
Detailed description of the invention
Fig. 1: for the installation site figure of on-vehicle battery extinguishing device of the invention；
Fig. 2: for the principle assumption diagram of on-vehicle battery extinguishing device of the invention.
Specific embodiment
On-vehicle battery extinguishing device of the invention is installed near vehicle interior lithium battery box as shown in Figure 1:, including control
Case, fire suppression bottle, injection valve, sensor, host power supply, transmission module；Sensor is temperature sensor, smoke sensor device and
Optical sensor has injection valve on fire suppression bottle, and control cabinet connects each sensor and injection valve, and transmission module transmits fire alarm letter
Number, in order to timely alarm and passenger is evacuated, host power supply is the power supply of the equipment such as control cabinet.Wherein working principle are as follows: 1. temperature
Sensor is spent, temperature reaches a certain fixed value or the rate of climb is accelerated, then it is assumed that alarm.It is common to be set as, 60 °C of alarms,
Or 5 °C of alarms of rising per second；2. smoke sensor device, when environmental smoke value reaches a certain range alarm；3. optical sensor is surveyed
Measure the light of certain wavelength, necessarily there is light generation in kindling when.On-vehicle battery extinguishing device at work, needs vehicle to stop still
So work, it is therefore desirable to be powered for a long time using Vehicular battery.The present invention is opened by establishing model using temperature sensor as starting
It closes, is set to lithium battery interior, and other sensors are all in stop working state, when temperature sensor detects that temperature reaches
A certain early warning value, for example when 40 °C, start other sensors, therefore system power dissipation is greatly lowered.
As shown in Figure 2: the control cabinet of on-vehicle battery extinguishing device of the invention is battery self-extinguishing main control box, is connected
Driver's cabin combined aural and visual alarm is connect, by monitoring the multiple temperature sensors of cable connection, gas sensor and smoke sensor device, according to
The detection data of sensor opens the injection valve of fire suppression bottle, and injection valve connects fire-suppressant gas jet pipe, and extinguishing chemical passes through fire extinguishing
Gas spray pipe sprays.Each sensor is set on battery case, and fire-suppressant gas jet pipe covers entire battery case.
