Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to a fire extinguishing device for a lithium battery storage area. Background Art

[0002] Lithium batteries are a type of battery that uses lithium metal or lithium alloy as positive / negative electrode materials and a non-aqueous electrolyte solution. The batteries have high energy density, no memory effect and low self-discharge. However, they can be a safety hazard because they contain flammable electrolytes that can cause explosions and fires if damaged or improperly charged.

[0003] The inventors believe that the existing related technologies often have the following defects: the existing storage method of lithium batteries is usually to stack the lithium batteries in one place, which makes the lithium battery stack prone to spontaneous combustion and explosion in a high-temperature environment, causing a fire. If the fire is not controlled in time, after the lithium battery stack is fully burned, the fire will be large and difficult to extinguish, causing the fire to continue to spread, affecting surrounding buildings, and causing major safety hazards and economic losses. Utility Model Content

[0004] The technical problem to be solved by the present invention is that the existing technology has the disadvantage that it is impossible to detect and control the fire in time after the lithium battery spontaneously combusts. For this reason, we propose a fire extinguishing device for a lithium battery storage area.

[0005] In order to achieve the above-mentioned purpose, the present application adopts the following technical solution: a lithium battery storage area fire extinguishing device, comprising a storage area, a partition fixedly connected to the top of the storage area, a dry powder storage tank provided at the rear end of the storage area, a control terminal installed on the top of the dry powder storage tank, a drive device installed on the top of the control terminal, delivery pipes installed at both ends of the top of the control terminal, three mounting pipes installed at the end of the delivery pipe away from the control terminal, several nozzles installed at the bottom of the mounting pipe, and two smoke sensors installed inside the storage area.

[0006] Preferably, an alarm is installed at the front end of the mounting tube.

[0007] Preferably, two circular grooves are provided on one side of the storage area, a bracket is fixedly connected to the inner wall of the circular groove, a driving motor is installed on one side of the bracket, and a fan is installed on the output end of the driving motor.

[0008] Preferably, a plurality of extension columns are fixedly connected to the bottom of the storage area, and three extension plates are fixedly connected to the bottom of the extension columns.

[0009] Preferably, the front end of the storage area is rotatably connected to a long board via a hinge.

[0010] Preferably, a long groove is provided in the middle of the long plate, and the inner wall of the long groove is slidably connected to the surface of the partition.

[0011] Preferably, the fans are placed on both sides of the rear end of the storage area, and one side of the fan is opposite to the opening of the storage area.

[0012] The technical effects and advantages of this utility model are:

[0013] In the present invention, when the lithium batteries stored inside the storage area burn, the smoke generated by the burning is detected by the smoke sensor and transmitted to the control terminal, so that the control terminal starts the driving device, pumps the dry powder inside the dry powder storage tank, outputs it to the nozzle through the conveying pipe and the installation pipe, and then sprays the dry powder downward into the storage area through the nozzle, so that the dry powder covers the flames and extinguishes the burning lithium batteries in the storage area, thereby realizing real-time monitoring of the lithium batteries inside the storage area and achieving the effect of quickly extinguishing the burning lithium batteries, thereby preventing the lithium battery fire from becoming large and difficult to extinguish.

The dry powder is then sprayed downward into the storage area 1 through the nozzle 8, so that the dry powder covers the flames and extinguishes the burning lithium batteries in the storage area 1, thereby realizing real-time monitoring of the lithium batteries inside the storage area 1 and achieving the effect of quickly extinguishing the burning lithium batteries, thereby preventing the lithium battery fire from becoming large and difficult to extinguish.

[0022] Reference Figure 1 - Figure 4 As shown, in this embodiment: an alarm 10 is installed at the front end of the mounting tube 7. When the lithium batteries stored inside the storage area 1 dissipate heat, the smoke is detected by the smoke sensor 9 and the information is transmitted to the control terminal 4. The control terminal 4 then recognizes the information and drives the alarm 10 to operate, so that the alarm light of the alarm 10 flashes and a siren sounds to warn the surrounding personnel, so that nearby personnel can detect the fire in time and respond to it, thereby reducing the losses caused by the fire.

[0023] Reference Figure 5 As shown, in this embodiment: two circular grooves 11 are opened on one side of the storage area 1, and the inner wall of the circular groove 11 is fixedly connected with a bracket 12, and a driving motor 13 is installed on one side of the bracket 12. The output end of the driving motor 13 is installed with a fan 14. When the staff starts the driving motor 13 to drive the fan 14 to rotate, the fan 14 generates wind force, which physically cools the lithium batteries stored in the storage area 1 by wind force, and dissipates the heat inside the storage area 1, thereby reducing the heat generated by the stacking of lithium batteries in the storage area 1 and preventing the lithium batteries from spontaneously combusting due to excessive heat.

[0024] Reference Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, in this embodiment: a plurality of extension columns 15 are fixedly connected to the bottom of the storage area 1, and three extension plates 16 are fixedly connected to the bottom of the extension columns 15. The extension columns 15 and the extension plates 16 are set by the staff, so that the storage area 1 is erected by the extension columns 15 and the extension plates 16 and away from the ground. The non-combustible material design of the extension columns 15 and the extension plates 16 prevents the lithium batteries placed inside the storage area 1 from burning and spreading to cause the ground temperature to be too high, causing the surrounding foreign objects to burn. At the same time, the multiple interval design of the extension columns 15 makes it convenient for the staff to use a forklift to move the storage area 1.

[0025] Reference Figure 1 - Figure 5 As shown, in this embodiment: the front end of the storage area 1 is connected to a long board 17 by a hinge. The long board 17 connected by the hinge at the front end of the storage area 1 makes the front end of the storage area 1 have a sloped inclined board, so that the staff can walk into the storage area 1 through the long board 17 when carrying lithium batteries up and down, which is convenient for carts and other tools to enter and exit the storage area 1 to carry goods.

[0026] Reference Figure 1 、 Figure 3 and Figure 4 As shown, in this embodiment: a long groove 18 is opened in the middle of the long board 17, and the inner wall of the long groove 18 is slidingly connected to the surface of the partition 2. Through the provision of the long groove 18, when the long board 17 can be rotated upward to the inside of the storage area 1, the partition 2 is plugged into the long groove 18 and no longer blocks the moving trajectory of the long board 17, so that the long board 17 can be stored in the storage area 1.

[0027] Reference Figure 2 and Figure 5 As shown, in this embodiment: the fan 14 is placed on both sides of the rear end of the storage area 1, and one side of the fan 14 is opposite to the opening of the storage area 1. Through the design of the fan 14, the wind force generated by the fan 14 forms convection with the opening of the storage area 1, thereby improving the efficiency of the wind flow inside the storage area 1 and making it easier to discharge the heat inside the storage area 1.

[0028] Working principle: When the lithium batteries stored in the storage area 1 burn, the smoke generated by the burning is detected by the smoke sensor 9 and transmitted to the control terminal 4, so that the control terminal 4 starts the driving device 5, pumps the dry powder in the dry powder storage tank 3, and outputs it to the nozzle 8 through the conveying pipe 6 and the installation pipe 7. The dry powder is then sprayed downward into the storage area 1 through the nozzle 8, so that the dry powder covers the flames and extinguishes the burning lithium batteries in the storage area 1, realizing real-time monitoring of the lithium batteries in the storage area 1, achieving the effect of quickly extinguishing the burning lithium batteries, and preventing the lithium battery fire from being too large and difficult to extinguish. When the lithium batteries stored in area 1 are dissipating heat, the smoke sensor 9 detects the smoke and transmits the information to the control terminal 4. The control terminal 4 then recognizes the information and drives the alarm 10 to operate, causing the alarm light of the alarm 10 to flash and sound a siren to warn the surrounding personnel, so that the nearby staff can find the fire in time and respond to it, thereby reducing the loss caused by the fire. The staff starts the drive motor 13 to drive the fan 14 to rotate, so that the fan 14 generates wind force, which physically cools the lithium batteries stored in the storage area 1 and blows away the heat inside the storage area 1, thereby reducing the storage area. The heat generated by the lithium batteries stacked inside the storage area 1 is prevented from spontaneous combustion due to excessive heat. The extension columns 15 and extension plates 16 set by the staff make the storage area 1 be erected by the extension columns 15 and extension plates 16, away from the ground. The non-combustible material design of the extension columns 15 and extension plates 16 prevents the lithium batteries in the storage area 1 from burning and spreading to the ground, causing the ground temperature to be too high and causing the surrounding foreign objects to burn. At the same time, the multiple intervals of the extension columns 15 make it easy for the staff to use a forklift to move the storage area 1. The long plate 17 connected by the hinge at the front end of the storage area 1 makes the front end of the storage area 1 have There is a sloped inclined board, so that when the staff carry lithium batteries up and down, they can walk into the storage area 1 through the long board 17, which is convenient for carts and other equipment to move goods in and out of the storage area 1. Through the long slot 18, when the long board 17 can be rotated upward to the inside of the storage area 1, the partition 2 is plugged into the long slot 18 and no longer blocks the moving trajectory of the long board 17, so that the long board 17 can be stored in the storage area 1. Through the design of the fan 14, the wind force generated by the fan 14 forms convection with the opening of the storage area 1, thereby improving the efficiency of the wind flow inside the storage area 1 and making it easier to discharge the heat inside the storage area 1.
