The fixed plates 7 are located directly below the placement slots on the placement frame 4, and the number of the fixed plates 7 is the same as the number of the placement slots. Two symmetrically distributed first springs 8 are fixedly installed on the top of the fixed plate 7. A placement plate 9 is fixedly installed between the two first springs 8. The top of the placement plate 9 contacts the bottom of the lithium battery body 5, so that when the lithium battery body 5 is inserted into the placement slot of the placement frame 4, the bottom of the lithium battery body 5 can contact the top of the placement plate 9, and the weight of the lithium battery body 5 is used to press the placement plate 9, so that the placement plate 9 compresses the first spring 8. Two telescopic rods 33 are fixedly installed between the fixed plate 7 and the placement plate 9. The telescopic rod 33 is located at The inner side of the first spring 8 makes the telescopic rod 33 provide support for the placement plate 9 to prevent the first spring 8 from bending, so that the placement plate 9 can move downward in a horizontal state. Two symmetrically distributed rack plates 10 are fixedly installed on the side of the placement plate 9 close to the fixed plate 7. When the placement plate 9 moves, it can drive the rack plate 10 to move downward synchronously. A rotating rod 11 is provided on the outside of the rack plate 10, and a sleeve 12 is fixedly installed on the top of the fixed plate 7.

The height of the rack on the rack plate 10 is less than the entire rack plate 10. The height of the body, when the placement plate 9 stops moving, the rack on the rack plate 10 can be away from the positioning gear 13, and the number of positioning gears 13 is the same as the number of rack plates 10, so that each placement plate 9 can drive the rotating rod 11 to rotate intermittently when it moves downward in sequence.

The heat dissipation mechanism in the figure includes a first heat conducting plate 19 arranged on the inner side of the refrigerant box 18, and a plurality of second heat conducting plates 20 distributed at equal intervals are fixedly installed on the outer side of the first heat conducting plate 19. The second heat conducting plates 20 slide through the refrigerant box 18, and a heat conducting plate 21 is fixedly installed between the plurality of second heat conducting plates 20. The side of the heat conducting plate 21 away from the second heat conducting plate 20 contacts the outer side of the lithium battery body 5, so that the heat conducting plate 21 conducts the heat generated by the lithium battery body 5 to the second heat conducting plate 20, and the second heat conducting plate 20 then conducts the heat to the refrigerant box 18 through the first heat conducting plate 19. The refrigerant in the refrigerant box 18 absorbs the heat on the first heat conducting plate 19 to achieve heat dissipation of the lithium battery body 5, and when the refrigerant box 18 is close to the lithium battery body 5, the second heat conducting plate 20 can be retracted into the refrigerant In the box 18, the heat absorption efficiency of the refrigerant box 18 to the second heat conducting plate 20 is improved, that is, as the refrigerant box 18 moves, the heat dissipation efficiency of the lithium battery body 5 can be improved. A sealing frame 39 is fixedly installed on the outside of the refrigerant box 18 for limiting the sliding of the second heat conducting plate 20, thereby improving the sealing between the second heat conducting plate 20 and the refrigerant box 18. Two symmetrically distributed water pumps 22 are fixedly installed on the side of the refrigerant box 18 away from the heat conducting plate 21. The two water pumps 22 are respectively used to transport refrigerant and discharge refrigerant to facilitate heat discharge. A delivery pipe 23 is fixedly installed on the outside of the water pump 22. The delivery pipe 23 is a retractable structure, which is convenient for the refrigerant box 18 to stretch the delivery pipe 23. A refrigerant delivery box 24 is fixedly installed between the two delivery pipes 23. The refrigerant delivery box 24 is docked with the heat exchanger 6 through the docking pipe 25. The refrigerant delivery box 24 conducts heat to the heat exchanger 6 for heat dissipation.

[0037] Example 3: Please refer to Figures 1-8, this embodiment is further explained for other embodiments. The protective mechanism in the figure includes two symmetrical heat dissipation boxes 26 fixedly installed on the outside of the box body 1. A baffle 27 is slidably installed on the inner side of the heat dissipation box 26. The outer sides of the heat dissipation box 26 and the baffle 27 are both provided with a plurality of heat dissipation holes distributed at equal distances. When the heat dissipation holes on the baffle 27 are aligned with the heat dissipation holes on the heat dissipation box 26, it is convenient for air circulation in the box body 1 and for heat dissipation of the lithium battery body 5 in the box body 1. The distance between adjacent heat dissipation holes is greater than the width of the heat dissipation holes, so that when the baffle 27 moves, the baffle 27 can block the heat dissipation holes on the heat dissipation box 26. The heat dissipation holes are used to seal the box body 1. A mounting plate 28 is fixedly installed on the top of the heat dissipation box 26. An air bag 29 is fixedly installed on the bottom of the mounting plate 28. A plurality of elastic clips 30 are fixedly installed on the inside of the heat dissipation box 26 in a symmetrical distribution. A card slot for the elastic clip 30 is provided on the outside of the baffle 27 so that the elastic clip 30 can suspend and position the baffle 27 in the heat dissipation box 26. A pressing groove for the elastic clip 30 to limit the sliding of the baffle 27 is provided on the top of the baffle 27. The top of the pressing groove is an open structure. When the baffle 27 moves downward, the elastic clip 30 can slide out of the card slot of the baffle 27 and slide along the baffle 27. The baffle 27 moves along the pressure groove of the baffle 27, and the elastic clip 30 is used to push the baffle 27 to move downward quickly. A curved heat-conducting rod 40 is provided on the inner side of the airbag 29. A heat-conducting support rod 31 is fixedly installed between the two ends of the two curved heat-conducting rods 40. The outer side of the heat-conducting support rod 31 contacts the outer side of the lithium battery body 5. A plurality of contact plates 38 distributed at equal distances are fixedly installed on the outer side of the heat-conducting support rod 31. The heat-conducting support rod 31 contacts the outer side of the lithium battery body 5 through the contact plate 38, so that the temperature of the outer side of the lithium battery body 5 can be conducted to the contact plate 38 and passed through the heat-conducting support rod 31. The hot support rod 31 enters the curved heat-conducting rod 40, and the curved heat-conducting rod 40 heats the gas in the airbag 29. When the lithium battery body 5 burns, the height generated can make the airbag 29 expand rapidly and contact the baffle 27, which can push the baffle 27 out of the elastic clip 30 to seal the heat dissipation box 26. The inner sides of the mounting plate 28 and the heat dissipation box 26 are both provided with cavities for installing the heat-conducting support rod 31. A U-shaped pull rod 37 is fixedly installed on the outer side of the baffle 27. A slide groove for the U-shaped pull rod 37 to limit the sliding of the U-shaped pull rod 37 is provided on the outer side of the heat dissipation box 26, which is convenient for pulling the U-shaped pull rod 37 to reset the baffle 27.

[0038] Working principle: First, the staff inserts the lithium battery body 5 into the placement slot of the placement frame 4, the bottom of the lithium battery body 5 contacts the top of the placement plate 9, and the outer side of the lithium battery body 5 contacts the outer side of the thermal conductive plate 21. The weight of the lithium battery body 5 is used to press the placement plate 9, so that the placement plate 9 compresses the first spring 8 and drives the rack plate 10 to move downward synchronously. The rack on the rack plate 10 contacts the corresponding positioning gear 13, so that the rack plate 10 drives the rotating rod 11 to rotate through the positioning gear 13, and the rotating rod 11 drives the screw 15 on the mounting frame 14 through the bevel gear 16, so that The two adjacent screws 15 drive the U-shaped bracket 17 to move, and the U-shaped bracket 17 drives the refrigerant box 18 to be close to the outer side of the lithium battery body 5, so that the second heat conducting plate 20 is correspondingly received in the inner side of the refrigerant box 18, and when the placement plate 9 stops moving, the rack on the rack plate 10 is away from the positioning gear 13. At the same time, when the rotating rod 11 rotates, the spherical groove on its outer side can push the block 34 to move along the inner side of the sleeve 12 and compress the second spring 35. When the rotating rod 11 stops rotating, the rebound force of the second spring 35 is used to push the block 34 into the spherical groove on the outer side of the rotating rod 11 to achieve the positioning of the rotating rod 11. To prevent the rotating rod 11 from rotating, the staff then loads the next lithium battery body 5 into another placement slot of the placement frame 4, so that the placement plate 9 directly below the lithium battery body 5 drives the corresponding rack plate 10 to move, and the rack plate 10 can drive the rotating rod 11 to rotate again through the positioning gear 13, and the refrigerant box 18 can move again, and the distance between it and the lithium battery body 5 is reduced. As a result, as the number of lithium battery bodies 5 increases, the distance between the refrigerant box 18 and the lithium battery body 5 will gradually decrease, and the second heat conducting plate 20 can be further collected in the refrigerant box 18, thereby improving the refrigerant in the refrigerant box 18 to the second heat conducting plate 20 and the first The heat absorption efficiency of the heat conducting plate 19 is improved. Finally, the staff starts the heat exchanger 6, so that the low-temperature refrigerant enters the refrigerant box 18 through the refrigerant delivery box 24, the delivery pipe 23 and the water pump 22. The heat generated by the lithium battery body 5 is transferred to the heat conducting plate 21, so that the heat conducting plate 21 transfers the heat to the refrigerant box 18 through the second heat conducting plate 20 and the first heat conducting plate 19. The refrigerant in the refrigerant box 18 can discharge the heat from another water pump 22 and discharge the heat through the heat exchanger 6. Thus, the lithium battery body 5 is kept in a low-temperature state, thereby achieving the effect of automatic temperature regulation and ensuring the normal operation of the lithium battery body 5.

[0039] When the lithium battery body 5 in the box body 1 burns, the high temperature generated can be conducted to the heat-conducting support rod 31 through the contact plate 38, and enters the air bag 29 through the heat-conducting support rod 31 and the curved heat-conducting rod 40, so that the gas in the air bag 29 expands, and the air bag 29 can contact the top of the baffle 27 and push the baffle 27 to move downward, so that the slot on the baffle 27 is separated from the elastic clip 30, and the elastic clip 30 is used to insert the elastic clip 30 into the pressure groove of the baffle 27 by utilizing the rebound force of the elastic clip 30. The elastic clip 30 can push the baffle 27 to move downward quickly, so that the elastic clip 30 seals the heat dissipation holes on the heat dissipation box 26, and the box body 1 can be in a sealed state, achieving the effect of flame retardancy and fire extinguishing, thereby improving the safety of the box body 1 and facilitating timely fire extinguishing by the staff.
