All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, shall fall within the scope of the present application.
Referring to fig. 1-9, the application provides a flame-retardant new energy battery box, which comprises a box body 1 and a plurality of battery storage modules 2 arranged in an array manner in the box body 1, wherein a radiating hole structure is arranged on the box body 1. When the battery storage module is used, the battery can be stored in the battery storage module 2 in the box body 1, the heat dissipation hole structure on the box body 1 enables the box body 1 to be communicated with the outside, and heat in the box body 1 can be conducted outwards through the heat dissipation hole structure.
Further, the heat dissipation hole structure comprises an air inlet 31 and an air outlet 32 which are symmetrically arranged at two ends of the box body 1 respectively; the air inlet 31 and the air outlet 32 are respectively provided with an inlet fan and an outlet fan. The air flow flowing in the box body 1 can be forced to dissipate heat of the battery by the air inlet fan and the air outlet fan, so that the heat dissipation effect is improved.
The battery storage module 2 is used as a mechanism for storing batteries, and comprises a flame retardant box 21, a battery storage box 22, a fire extinguishing component 23 and a temperature control component 24, wherein when the batteries are prevented from burning, the burning batteries are isolated from other batteries in the box body 1 in time, and the flames of the burning batteries are extinguished, so that the flames are prevented from spreading.
The fire-retardant box 21 is formed inside with a first storage chamber 211 containing fire-extinguishing fluid. In a normal state, the fire extinguishing fluid is stored in the first storage chamber 211, and when the battery burns, the fire extinguishing fluid can be discharged to extinguish the flame.
The battery storage box 22 comprises limit plates 221 which are symmetrically and vertically fixed at two ends of the top of the heat dissipation flame-retardant box 21, a plurality of square heat insulation frames 222 which are vertically and slidably assembled between the two limit plates 221, and a linkage assembly 223 which is connected to the plurality of square heat insulation frames 222, wherein a battery storage chamber 224 is enclosed inside the plurality of square heat insulation frames 222, positioning sheets 225 are uniformly arranged inside the plurality of square heat insulation frames 222, a cover body 226 is arranged at the top of the uppermost square heat insulation frame 222, an elastic shrinkage piece 2263 is arranged at the bottom of the cover body 226, the elastic shrinkage piece 2263 can be abutted to the top of a battery and can be compressed, the square heat insulation frames 222 at the lowermost are fixedly connected with the top of the heat dissipation flame-retardant box 21, and the linkage assembly 223 is used for driving other square heat insulation frames 222 except the square heat insulation frames 222 at the lowermost to vertically slide between the two limit plates 221, so that equidistant gaps are formed between the adjacent square heat insulation frames 222. Under normal conditions, the battery is located in the battery storage chamber 224 and is limited by the positioning sheets 225 on the inner sides of the square heat insulating frames 222, at this time, the linkage assembly 223 can drive other square heat insulating frames 222 except for the square heat insulating frame 222 located at the lowest position to vertically slide between the two limiting plates 221, so that equidistant gaps (the gaps are larger than O) are formed between the adjacent square heat insulating frames 222, flowing air flow in the box 1 can enter the battery storage chamber 224 through the equidistant gaps between the adjacent square heat insulating frames 222, heat generated by the battery is taken away, so that the battery dissipates heat, when the battery burns, the linkage assembly 223 drives the adjacent square heat insulating frames 222 to form equidistant gaps to be zero, namely the adjacent square heat insulating frames 222 are abutted against each other, at this time, the square heat insulating frames 222 and the cover 226 form a sealed heat insulating chamber, so that the burning battery is isolated from other batteries, on one hand, the spread of fire is prevented, heat is prevented from being conducted, and on the other hand, oxygen is isolated, and the battery is prevented from burning.
It should be noted that, under the normal state, the plurality of square heat insulating frames 222 in the present technical solution are driven by the linkage assembly 223, so that the adjacent square heat insulating frames 222 form equidistant gaps (the equidistant gaps are larger than O), the airflow flowing inside the box 1 can enter the battery storage from the plurality of equidistant gaps to uniformly dissipate heat of each part of the battery, and when the battery burns (generally, the battery burns at a higher speed, therefore, if the isolating speed is slower, the fire may spread to other positions), the present technical solution can synchronously move the plurality of square heat insulating frames 222 under the driving of the linkage assembly 223, so as to quickly isolate the burning battery, and during winter, the adjacent square heat insulating frames 222 can form equidistant gaps to O to store the battery in a closed state, thereby avoiding the over-low temperature of the battery and affecting the use of the battery.
The fire extinguishing assembly 23 comprises a spray pipe 231 vertically arranged on the inner side of the square heat insulation frames 222 and a liquid injection piece 232 arranged in the first storage chamber 211 and connected with the input end of the spray pipe 231, wherein the liquid injection piece 232 is used for injecting fire extinguishing fluid in the first storage chamber 211 into the spray pipe 231, and spray holes are uniformly formed in the outer side of the spray pipe 231. When the battery burns, the liquid injection member 232 can inject the fire extinguishing fluid in the first storage chamber 211 into the spray pipe 231 and then discharge the fire extinguishing fluid from the spray hole of the spray pipe 231, so as to extinguish the flame burning in the battery.
The temperature control assembly 24 includes a temperature sensor disposed within the storage chamber. The temperature sensor can monitor the temperature in the battery storage chamber 224 in real time, and can isolate the burning battery in time and start the liquid injection piece 232 to extinguish the flame through the fire extinguishing fluid when the battery temperature reaches a threshold value, namely the temperature at which the battery burns, so as to prevent the fire from spreading further.
In this particular embodiment, the fire suppression flow agent is perfluorinated hexanone. On the one hand, the fire extinguishing concentration of the perfluorinated hexanone is 4-6%, the safety margin is higher, and the perfluorinated hexanone is safer to human bodies when in use. On the other hand, the perfluoro-hexanone is liquid at normal temperature and does not belong to dangerous goods, and can be safely stored and transported (including air transportation) in a wider temperature range by using a common container in a normal pressure state, and the storage and transportation of a pressure container are not required unlike other halon substitutes. Of course, and without limitation, other fire suppression fluids may be employed as the fire suppression fluid.
In this embodiment, the linkage assembly 223 includes a scissor fork type expansion frame symmetrically and vertically disposed at two sides of the square heat insulation frames 222, the hinge shaft of each middle hinge node 2231 in the expansion direction of the scissor fork type expansion frame is fixedly connected with the square heat insulation frames 222, and a linear driver for driving the scissor fork type expansion frame to expand and contract is disposed in one of the diamond-shaped lattices 2232 of the scissor fork type expansion frame. The scissor type expansion bracket is in the prior art, and can simultaneously change the integral diamond-shaped check 2232 to realize expansion when one diamond-shaped check 2232 changes. The linear driver is an electric telescopic rod, and two ends of the linear driver are respectively hinged to two sides of one diamond-shaped lattice 2232 of the scissor type telescopic frame so as to drive the scissor type telescopic frame to stretch and retract.
Further, a second storage chamber 212 for containing cooling liquid is formed in the flame retardant box 21 above the first storage chamber 211, a liquid cooling channel 2221 having a frame shape is hollow in the square heat insulation frame 222, the positioning sheet 225 is an elastic reed, one end of the elastic reed extends into the liquid cooling channel 2221, and a connecting pipe 2222 is arranged in the middle of two ends of the square heat insulation frame 222; of the two connection pipes 2222 of the other square heat insulating frames 222, one connection pipe 2222 is connected with the connection pipe 2222 of the lower square heat insulating frame 222 thereof through a hose, and the other connection pipe 2222 is connected with the upper square heat insulating frame 222 thereof through a hose, except for the lowermost square heat insulating frame 222 and the uppermost square heat insulating frame 222; two connection pipes 2222 of the lowermost square-type heat insulation frame 222, one of the connection pipes 2222 being connected to the liquid pump 4 provided in the second storage chamber 212 through a pipe, the other connection pipe 2222 being connected to the connection pipe 2222 of the square-type heat insulation frame 222 above it through a hose; two connection pipes 2222 of the uppermost square insulation frame 222, one of the connection pipes 2222 is connected to the second storage chamber 212 through a telescopic pipe 2223, and the other connection pipe 2222 is connected to the connection pipe 2222 of the square insulation frame 222 therebelow through a hose. In a normal state, the air flowing in the box body 1 dissipates heat of the battery, when the temperature sensor detects that the temperature of a certain battery storage chamber 224 rises to a first preset value, at this time, the liquid pump 4 is started, the liquid pump 4 can continuously guide the cooling liquid in the second storage chamber 212 into the bottommost square heat insulation frame 222 through a pipeline, so that the cooling liquid sequentially enters the liquid cooling channel 2221 of the square heat insulation frame 222 from bottom to top, the elastic reed of the square heat insulation frame 222 can absorb the heat of the battery in a heat conduction mode, and then the cooling liquid through the liquid cooling channel 2221 takes away the heat so as to dissipate the heat of the battery through air cooling and water cooling. When the temperature of the battery storage chamber 224 increases to the second preset value, i.e. when the battery burns, the flowing cooling liquid in the liquid cooling channel 2221 of the square heat insulation frame 222 can improve the heat insulation effect of the square heat insulation frame 222, so as to prevent the temperature in the battery storage chamber 224 from being conducted into other battery storage chambers 224, thereby causing the temperature of other batteries to increase.
In this embodiment, the positioning sheet 225 forms an angle with the top surface of the square insulation frame 222. The contact area with the battery can be increased, and the heat dissipation and limiting effects are improved.
In this embodiment, the cover 226 is further provided with a pressure relief tube 2261, and the pressure relief tube 2261 is provided with a pressure relief valve 2262. During the fire extinguishing process, after the air pressure in the battery storage chamber 224 is increased, the air is discharged outwards through the pressure release pipe 2261, so that explosion is avoided.
The foregoing is only a preferred embodiment of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art, who is within the scope of the present application, should make equivalent substitutions or modifications according to the technical scheme of the present application and the inventive concept thereof, and should be covered by the scope of the present application.
