[0036] like Figure 3 and Figure 4As shown, the closing component also includes a fixed square column 8; the two sides of the explosion-proof box 1 and the positions corresponding to the closing column 5 are rotatably connected to the fixed square column 8; the inner side of the fixed square column 8 is rotatably connected with a rotating column 9; the end of the rotating column 9 close to the closing column 5 is fixedly connected with a second bevel gear 10; the second bevel gear 10 is meshed with the closing gear 6, and the closing component also includes a linkage column 12; one end of the explosion-proof box 1 and the position corresponding to the fixed square column 8 are rotatably connected to the linkage column 12; the two sides of the linkage column 12 are fixedly connected with a third bevel gear 13; the end of the rotating column 9 away from the closing column 5 is fixedly connected with a fourth bevel gear 14; the third bevel gear 13 is meshed with the fourth bevel gear 14; the outer side of the explosion-proof box 1 and the position corresponding to the linkage column 12 is fixedly connected with an L-shaped frame 11; the side of the L-shaped frame 11 away from the explosion-proof box 1 is fixedly connected with a servo motor 15; the output end of the servo motor 15 is fixedly connected to the linkage column 12. During operation, when the smoke alarm in the explosion-proof box 1 starts to warn and needs to drive the sealing plate 2 to move, the smoke alarm starts the servo motor 15, and then the output end of the servo motor 15 drives the linkage column 12 to rotate, so that the linkage column 12 drives the third bevel gear 13 to rotate, and then the third bevel gear 13 drives the rotating column 9 and the second bevel gear 10 to rotate through the fourth bevel gear 14, so that the multiple groups of sealing plates 2 located on both sides of the explosion-proof box 1 can be driven to move simultaneously through the linkage column 12 and the third bevel gear 13.

[0037] like Figure 2 and Figure 5 As shown, cooling racks 16 are fixedly connected to the two sides of the bottom of the inner side of the explosion-proof box 1 and the positions corresponding to the sealing plate 2; and multiple cooling fans 17 are fixedly connected to the inner side of the cooling rack 16. When working, when the device is normally used, cooling air is continuously input into the explosion-proof box 1 through the cooling fan 17, so as to reduce the heat generated by the lithium battery pack during use, and further protect the lithium battery pack during use.

[0038] like Figure 5 As shown, the fire extinguishing assembly includes a fire extinguishing box 18; the two sides of the inner side of the explosion-proof box 1 and the positions corresponding to the cooling rack 16 are fixedly connected to the fire extinguishing box 18; the bottom end of the fire extinguishing box 18 is slidably connected to a fire extinguishing plate 19; the bottom end of the fire extinguishing plate 19 is fixedly connected to a mobile rack 20; the inner side of the mobile rack 20 is slidably connected to a fire extinguishing column 21; the fire extinguishing column 21 is fixedly connected to the explosion-proof box 1. During operation, through the design of the positions of the fire extinguishing box 18 and the cooling fan 17, after the fire extinguishing box 18 is opened, the fire extinguishing powder falling inside it is quickly blown away by the cooling fan 17 into the inside of the explosion-proof box 1, so that it can quickly extinguish the burning lithium battery pack in the explosion-proof box 1.

[0039] like Figure 6As shown, the fire extinguishing assembly also includes a transmission frame 22; the inner side of the explosion-proof box 1 and the position corresponding to the fire extinguishing plate 19 are fixedly connected to the transmission frame 22; the first fire extinguishing rack 23 is fixedly connected to the side of the sealing plate 2 and the position corresponding to the transmission frame 22; the inner side of the transmission frame 22 is rotatably connected to the fire extinguishing gear 24; the fire extinguishing gear 24 is meshed and connected with the first fire extinguishing rack 23; the side of the mobile frame 20 close to the transmission frame 22 is fixedly connected to the second fire extinguishing rack 25; the second fire extinguishing rack 25 is meshed and connected with the fire extinguishing gear 24. During operation, when the sealing plate 2 begins to close through the closing assembly, it drives the fire extinguishing gear 24 on the transmission frame 22 to rotate through the first fire extinguishing rack 23, and then drives the second fire extinguishing rack 25 and the fire extinguishing plate 19 to move to the opposite position to the movement of the sealing plate 2 through the fire extinguishing gear 24, so that the fire extinguishing plate 19 is opened under the fire extinguishing box 18, which is convenient for releasing the limit of the fire extinguishing powder in the fire extinguishing box 18.

[0040] like Figure 5 As shown, the top of the inner side of the fire extinguishing box 18 is detachably connected to a cover plate 26; the bottom end of the cover plate 26 is fixedly connected to a plurality of downward pressure springs 27; the bottom end of the downward pressure spring 27 is fixedly connected to a downward pressure plate 28. During operation, when the fire extinguishing assembly is opened, the downward pressure plate 28 is driven downward by the elastic characteristics of the downward pressure spring 27, so that the fire extinguishing powder in the fire extinguishing assembly can be quickly discharged from the fire extinguishing assembly through the downward pressure plate 28, so that the open fire on the lithium battery can be quickly extinguished.

[0041] like Figure 7 As shown, both sides of the explosion-proof box 1 and the positions corresponding to the sealing plate 2 are fixedly connected with sealing frames 30; a sealing groove 29 is provided on the side of the sealing plate 2 close to the sealing frame 30; a plurality of rubber strips 32 are fixedly connected to the side of the sealing frame 30 close to the sealing plate 2; a rubber column 31 is provided on the outer side of the rubber strip 32; and the rubber column 31 is fixedly connected to the sealing frame 30. During operation, when the sealing plate 2 moves to the position of the sealing frame 30, the elasticity of the rubber column 31 and the rubber strip 32 facilitates the movement of the rubber column 31 into the sealing groove 29 on the sealing plate 2, thereby improving the sealing effect of the sealing plate 2 and facilitating the isolation of the air in the explosion-proof box 1.

[0042] Working principle: During operation, when the lithium battery pack placed in the explosion-proof box 1 is burning, the smoke alarm inside it starts to warn, and then the closing component is activated through the smoke alarm, so that it drives the sealing plate 2 to move in the explosion-proof box 1, and the air in the explosion-proof box 1 is cut off from the outside through the sealing plate 2, isolating the air required for the combustion of the lithium battery. When the sealing plate 2 moves, it also drives the fire extinguishing component to open, so that the fire extinguishing agent in the fire extinguishing component falls downward, so that it can extinguish the open flame generated on the lithium battery pack, reduce the risk of continuous combustion and explosion of the lithium battery, and improve the explosion-proof effect of the device. When the smoke alarm in the explosion-proof box 1 starts the warning work, it drives the closing column 5 to rotate, and then the closing column 5 drives the closing gear 6 to rotate, and the rotation of the closing gear 6 drives the two adjacent sealing racks 4 to move. , and then the sealing plate 2 is driven to slide on the explosion-proof box 1 through the sealing rack 4, so that the sealing plate 2 isolates the cooling port of the sealing plate 2 to prevent the lithium battery in the explosion-proof box 1 from burning. When the smoke alarm in the explosion-proof box 1 starts to warn and needs to drive the sealing plate 2 to move, the smoke alarm starts the servo motor 15, and then the output end of the servo motor 15 drives the linkage column 12 to rotate, so that the linkage column 12 drives the third bevel gear 13 to rotate, and then the third bevel gear 13 drives the rotating column 9 and the second bevel gear 10 to rotate through the fourth bevel gear 14, so that the linkage column 12 and the third bevel gear 13 drive the multiple groups of sealing plates 2 located on both sides of the explosion-proof box 1 to move simultaneously when the device is used normally. The cooling fan 17 continuously inputs cooling air into the explosion-proof box 1 to reduce the heat generated by the lithium battery pack when in use, and further protects the lithium battery pack when in use. The design of the position of the fire extinguishing box 18 and the cooling fan 17 facilitates that after the fire extinguishing box 18 is opened, the fire extinguishing powder falling inside the fire extinguishing box 18 is quickly blown into the explosion-proof box 1 by the cooling fan 17, so that the burning lithium battery pack in the explosion-proof box 1 can be quickly extinguished. When the sealing plate 2 begins to close through the closing component, it drives the fire extinguishing gear 24 on the transmission frame 22 to rotate through the first fire extinguishing rack 23, and then drives the second fire extinguishing rack 25 and the fire extinguishing plate 19 toward the sealing plate 26 through the fire extinguishing gear 24. The sealing plate 2 moves to the opposite position, so that the fire extinguishing plate 19 is opened under the fire extinguishing box 18, which is convenient for releasing the limit on the fire extinguishing powder in the fire extinguishing box 18. When the fire extinguishing component is opened, the elastic force characteristics of the downward pressure spring 27 drive the lower pressure plate 28 to move downward, so that the fire extinguishing powder in the fire extinguishing component can be quickly discharged from the fire extinguishing component through the lower pressure plate 28, so that the open flame on the lithium battery can be quickly extinguished. When the sealing plate 2 moves to the position of the sealing frame 30, the elasticity of the rubber column 31 and the rubber strip 32 makes it convenient to move the rubber column 31 into the sealing groove 29 on the sealing plate 2, thereby improving the sealing effect of the sealing plate 2, and facilitating the isolation of the air in the explosion-proof box 1.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
