Specific implementation mode
The embodiment of battery system of the present invention：As shown in Figs 1-4, include the heat of battery pack, automatic detection battery pack temperature
Quick element, BMS（Battery management system）10 and automatic dry chemical extinguishing device.Automatic dry chemical extinguishing device includes length along front and back
To cylinder 3, cylinder 3 have the extinguishing chemical chamber for filling dry powder fire extinguishing agent 8, the cavity 31 positioned at extinguishing chemical chamber side.Fire extinguishing
Agent chamber includes chamber ontology and sealing plate 2, and chamber ontology includes cover board 6, right plate 11, baffle 5.Wherein baffle 5 by extinguishing chemical chamber with it is empty
Chamber separates, and there is baffle 5 hang plate section 51 diagonally downward and vertical plate section, vertical plate section to be connect with cover board 6, hang plate section 51
So that cavity forms up big and down small structure.The right end of sealing plate 2 is connected to 11 lower part of right plate by hinge 7.
Wind turbine 4 is equipped in cavity to its upper, wind turbine 4 is arranged there are four and along front and back direction interval, each two wind turbine
It it is one group, every group of wind turbine corresponds to a battery set electrode, and each group wind turbine is independently controlled.Wind turbine 4 is the wind turbine of direct current 12V.
When catching fire, it is selectively opened corresponding wind turbine and puts out a fire, the battery pack and electrical equipment for avoiding pollution from not catching fire.Cylinder
Length and entire battery module it is of same size, save installation space.The lower part of cavity is air outlet, due to the work of baffle
With the wind that wind turbine is blown downwards changes direction when passing through baffle, and narrow egress makes wind speed increase.
Automatic dry chemical extinguishing device further include for driving sealing plate to act and making it have the driving mechanisms of two working positions,
Driving mechanism uses frame-type electromagnet 1, the electromagnet fixed plate of frame-type electromagnet 1 to be connected on the barrel of cylinder.Frame
The power supply of formula electromagnet 1 is provided by the battery pack in battery system, is provided power supply using battery system itself, is no longer separately set electricity
Source.Specifically, temperature-sensitive element use temperature sensor 9, and with the BMS in battery system（Battery management system）Connection, BMS connect
After the signal of shrinkage temperature sensor 9 and extinguishing device open signal is converted it into, frame-type electromagnet 1 is made to act.Two works
As position includes closing chamber ontology with the closure position that prevents dry powder fire extinguishing agent from leaking and when temperature exceeds critical value door open structure with
Extinguishing chemical chamber is set to form the open position of spout 32.The position of spout is in the lower part of extinguishing chemical chamber and the side close to cavity,
When sealing plate 2 is opened, the wind that is just blown out by wind turbine 4 of dry powder fire extinguishing agent flowed out from nozzle 32 to and then dry powder fire extinguishing agent
Ejection is put out a fire.
As shown in Figure 1, further, in being equipped with blend stop 21 close to the side of spout on sealing plate 2,21 projection of blend stop is in sealing plate
2 inner surfaces, blend stop 21 have the binding face being bonded with the baffle 5 of chamber ontology, and dry powder fire extinguishing agent is realized not by fitting closely
Leakage.While closing, blend stop 21 can also play the role of following, provide gravity for the outflow of dry powder fire extinguishing agent, can also reduce
Frictional force when dry powder fire extinguishing agent flows out between sealing plate.
The operation principle of battery system of the present invention：In normal state, sealing plate 2, which is in, is closed position, and bullet may be used in hinge 7
Property hinge, the effect by spring is enclosed in baffle lower part, and only after electromagnet is powered, sealing plate 2 can just be opened.When temperature passes
When sensor 9 detects threshold value of the temperature value in battery pack higher than setting, signal is passed into signal adapter, temperature value signal
It is converted into the open signal of extinguishing device, passes to extinguishing device, and electromagnet is made to charge, sealing plate 2 is pulled downward on after energization, is sealed
Plate 2, which is swung, tilts down an angle, forms spout.Dry powder fire extinguishing agent positioned at extinguishing chemical intracavitary is flowed out from nozzle, with
This starts, wind turbine 4 blows dry powder fire extinguishing agent and sprayed to ignition point, puts out a fire after the reception signal of wind turbine 4 simultaneously.It goes out in dry powder
Fiery agent after use, can fill dry powder fire extinguishing agent into extinguishing chemical chamber again, and extinguishing device is repeatable to be utilized, reduce use at
This.
In the present embodiment, there is corresponding controller in BMS, the signal for receiving temperature sensor feedback, and will be warm
Angle value signal is handled, and in other embodiments, controller can also be used independent, independently be opened with BMS.
In other embodiments, the quantity of wind turbine can disclosure satisfy that each depending on actual battery module size
Battery pack is caught fire, and can be sprayed onto by dry powder fire extinguishing agent.Each wind turbine can be also controlled simultaneously, and be run together.
In other embodiments, electric pushrod can also be used in driving mechanism, such as electric pushrod obtains what controller was sent out
Fire extinguishing signal, electric pushrod action, the moved end of electric pushrod can pull sealing plate to lower swing to open spout.
In other embodiments, baffle can not also use bending harden structure, but use vertical plate, in order to enable dry powder goes out
Fiery agent easily flows out, and can be obliquely installed sealing plate, dry powder fire extinguishing agent is easily flowed out by gravity.
In other embodiments, heat-sensitive line in the prior art can also be used in temperature-sensitive element.
In other embodiments, frame-type electromagnet also can successively start with wind turbine.
