Specific embodiment
The embodiment of battery system of the present invention：As Figure 1-4, including battery pack, the heat of 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 has for filling the extinguishing chemical chamber of powder extinguishing agent 8, the cavity 31 positioned at extinguishing chemical chamber side.Fire extinguishing
Agent chamber includes chamber body and shrouding 2, and chamber body includes cover plate 6, right plate 11, baffle plate 5.Wherein baffle plate 5 by extinguishing chemical chamber with it is empty
Chamber separates, and baffle plate 5 has hang plate section 51 and vertical plate section diagonally downward, and vertical plate section is connected with cover plate 6, hang plate section 51
So that cavity forms up big and down small structure.The right-hand member of shrouding 2 is connected to the bottom of right plate 11 by hinge 7.
Blower fan 4 is provided with to its upper in cavity, and blower fan 4 there are four and along front and back direction interval setting, each two blower fan
It it is one group, every group of blower fan one battery set electrode of correspondence, each group blower fan is independently controlled.Blower fan 4 is the blower fan of direct current 12V.
When catching fire, it is selectively opened corresponding blower fan and is put out a fire, it is to avoid battery pack and electrical equipment that pollution is not caught fire.Cylinder
Length it is identical with the width of whole battery module, save installing space.The bottom of cavity is air outlet, due to the work of baffle plate
With, direction is changed when the wind that blower fan blows downwards is by baffle plate, narrow egress increases wind speed.
Automatic dry chemical extinguishing device also includes being used to drive shrouding to act and make it have two drive mechanisms of working position,
Drive mechanism uses frame-type electromagnet 1, and the electromagnet fixed plate of frame-type electromagnet 1 is connected on the barrel of cylinder.Framework
The power supply of formula electromagnet 1 is provided by the battery pack in battery system, and power supply is provided using battery system itself, no longer separately sets electricity
Source.Specifically, temperature-sensitive element use temperature sensor 9, and with battery system in BMS（Battery management system）Connection, BMS connects
After the signal of shrinkage temperature sensor 9 and extinguishing device open signal is converted it into, act frame-type electromagnet 1.Two works
Make position including closing chamber body with prevent powder extinguishing agent leak closure position and temperature exceed critical value when door open structure with
Extinguishing chemical chamber is set to form the open position of spout 32.The position of spout is in the bottom in extinguishing chemical chamber and near the side of cavity,
When shrouding 2 is opened, from the wind that is just blown out by blower fan 4 of powder extinguishing agent of the outflow of nozzle 32 to and then powder extinguishing agent
Ejection is put out a fire.
As shown in figure 1, further, in blend stop 21 is provided near the side of spout on shrouding 2, the projection of blend stop 21 is in shrouding
2 inner surfaces, blend stop 21 has the binding face fitted with the baffle plate 5 of chamber body, realizes powder extinguishing agent not by being brought into close contact
Leakage.While closing, blend stop 21 can also play following effect, for the outflow of powder extinguishing agent provides gravity, can also reduce
Frictional force when powder extinguishing agent flows out and between shrouding.
The operation principle of battery system of the present invention：In normal state, shrouding 2 is in closure position, and hinge 7 can use bullet
Property hinge, the effect by spring is enclosed in baffle plate bottom, and only after electromagnet is powered, shrouding 2 can just be opened.When temperature is passed
When the temperature value that sensor 9 detects in battery bag is higher than the threshold value of setting, by signal transmission to signal adapter, temperature value signal
The open signal of extinguishing device is converted into, extinguishing device is passed to, and makes electromagnet powered, shrouding 2 is pulled downward on after energization, sealed
The swing of plate 2 is a downward-sloping angle, forms spout.Powder extinguishing agent in extinguishing chemical chamber flows out from nozzle, with
This starts after the reception signal of blower fan 4 simultaneously, and blower fan 4 blows powder extinguishing agent and sprayed to ignition point, is put out a fire.Gone out in dry powder
After fiery agent has been used, can again to powder extinguishing agent is filled in extinguishing chemical chamber, extinguishing device is repeatable to be utilized, and reduction is used into
This.
In the present embodiment, there is corresponding controller in BMS, the signal for receiving temperature sensor feedback, and by temperature
Angle value signal is processed, and in other embodiments, controller also can independently be opened using independent with BMS.
In other embodiments, depending on the quantity of blower fan can be according to actual battery module size, disclosure satisfy that each
Battery pack is caught fire, and can be sprayed onto by powder extinguishing agent.Each blower fan can also be controlled simultaneously, and run together.
In other embodiments, drive mechanism can also use electric pushrod, such as electric pushrod to obtain what controller sent
Fire extinguishing signal, electric pushrod action, the moved end of electric pushrod can pull shrouding to lower swing to open spout.
In other embodiments, baffle plate can not also use bending plate structure, but use vertical plate, in order that obtain dry powder going out
Fiery agent is easily flowed out, and can be obliquely installed shrouding, and powder extinguishing agent is easily flowed out by gravity.
In other embodiments, temperature-sensitive element can also use heat-sensitive line of the prior art.
In other embodiments, frame-type electromagnet also can successively start with blower fan.
The embodiment of automatic dry chemical extinguishing device in the present invention, the structure of automatic dry chemical extinguishing device and above-mentioned battery system
