Specific embodiment
The embodiment of battery system of the present invention：As shown in Figs 1-4, the heat including 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 one side.Fire extinguishing
Agent chamber includes chamber body and sealing plate 2, and chamber body includes cover board 6, right plate 11, baffle 5.Wherein baffle 5 by extinguishing chemical chamber with it is empty
Chamber separates, and baffle 5 is connected with hang plate section 51 diagonally downward and vertical plate section, vertical plate section 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 at intervals there are four and along front and back direction, each two wind turbine
For 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.
It when catching fire, is selectively opened corresponding wind turbine and puts out a fire, avoid battery pack and electrical equipment that pollution is not caught fire.Cylinder
Length and entire battery module be 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 increases wind speed.
Automatic dry chemical extinguishing device further includes the driving mechanism that sealing plate is driven to act and makes it have two working positions,
Driving mechanism uses frame-type electromagnet 1, and the electromagnet fixed plate of frame-type electromagnet 1 is 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, acts frame-type electromagnet 1.Two works
Make position include closing chamber body with prevent dry powder fire extinguishing agent leak closure position and temperature exceed critical value when door open structure with
Extinguishing chemical chamber is made to form the open position of spout 32.The position of spout is in the lower part of extinguishing chemical chamber and the one side of close cavity,
When sealing plate 2 is opened, the dry powder fire extinguishing agent flowed out from nozzle 32 is just by the wind that wind turbine 4 is blown out 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 one 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 body, 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 employed 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 that the temperature value in battery pack is higher than the threshold value of setting, signal is passed into signal adapter, temperature value signal
The open signal of extinguishing device is converted into, passes to extinguishing device, and makes electromagnet charged, 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 repeats utilization, reduce use into
This.
In the present embodiment, there is corresponding controller in BMS, for receiving the signal of temperature sensor feedback, and by temperature
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
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 of the prior art can also be used in temperature-sensitive element.
In other embodiments, frame-type electromagnet also can successively start with wind turbine.
