Description

Technical Field

[0001] This invention relates to the field of battery protection technology, and in particular to a safety protection device for the sale and transportation of batteries. Background Technology

[0002] The core function of battery safety protection devices is to isolate risks and control hazards, ensuring that batteries do not cause safety accidents such as fire or explosion due to vibration, impact, short circuit or abnormal temperature during transportation, making them an essential device during battery transportation.

[0003] Currently, batteries are packaged and transported in separate boxes. During transportation, the boxes are easily damaged when subjected to impacts, making it difficult to protect the batteries. In addition, the existing box structures lack protective structures, making it impossible to deal with the fire when it occurs, thus affecting the safety of batteries that have not yet caught fire. Furthermore, the existing box structures store batteries tightly packed together, making it impossible to move or salvage batteries that have not yet caught fire when a fire occurs, resulting in significant economic losses.

[0004] Therefore, CN223162257U discloses a safety protection device for battery sales and transportation, which includes a base plate, a support frame on the base plate, and a storage structure on the base plate. The storage structure includes a storage box, a side plate, a cover plate, and a placement plate. Multiple sets of storage structures are provided. A partition plate is provided on the base plate between two storage boxes. Multiple partition plates are provided to store batteries through the storage structure. A protection structure is provided on the base plate. The protection structure includes a middle plate, a protection plate, a spring, and an airbag. Multiple sets of protection structures are provided. The protection plate is provided on the middle plate. A movable frame is movably provided on the support frame. A water tank and a sand box are fixedly provided on the movable frame. A threaded rod and a first sliding rod are provided on the support frame. The battery is protected by the protection structure.

[0005] The aforementioned safety protection device for battery sales and transportation protects the sides of the entire device by setting up a protective structure. When an external impact comes into contact with the protective plate, it pushes the protective plate to move along the fixed column and compresses the spring, thereby resisting the damage to the battery from the external impact. When the protective structure is laid flat, if the battery falls when it is being taken out, the battery will fall onto the airbag, reducing the damage to the battery from collisions with the ground, thus facilitating all-round protection of the battery.

[0006] By setting up sandboxes and water tanks on the mobile frame, when a battery in a storage box catches fire, rotating the threaded rod moves the mobile frame to the top of the storage box. Water is sprayed into the storage box through the nozzles, or sand is added to the storage box through the sandbox. The sand or water enters the storage box through the through holes in the cover plate to extinguish the fire. At the same time, the partition plate set on the bottom plate reduces the spread of the fire, facilitates the storage of batteries, and reduces the losses caused by the fire.

[0007] However, in actual use, the aforementioned safety protection device for battery sales and transportation has a problem: since battery combustion is an instantaneous event, the nozzle only moves after the battery has started burning. This causes a delay in sand and water spraying. At this time, the flames will burst out from the through hole, affecting other batteries. Furthermore, neither water nor sand spraying will isolate the heat generated by combustion, which will also affect the surrounding batteries.

[0008] Therefore, a new type of safety protection device for battery sales and transportation can be adopted to overcome the shortcomings of existing technologies. Summary of the Invention

[0009] The purpose of this invention is to solve the problems in the prior art by proposing a safety protection device for battery sales and transportation.

Detailed Implementation

[0043] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0044] Example 1: Refer to Figures 1-2 , Figures 4-6 , Figure 9 , Figure 11A safety protection device for battery sales and transportation includes a battery 2 and a storage rack 1 for transporting and storing the battery 2.

[0045] The storage rack 1 is composed of a number of storage frames 3. Two adjacent storage frames 3 are connected by a water injection pipe 4. The storage frames 3 are equipped with heat insulation modules and flame blocking modules.

[0046] The heat insulation module is used to absorb the heat generated by the combustion of battery 2 and prevent the heat from spreading to the surrounding area.

[0047] A buffer pad 5 is fixedly installed on the inner side of the storage box 3, which abuts against the side of the battery 2 to fix the battery 2.

[0048] The buffer pad 5 is made of flame-retardant material and has a certain protective function to prevent the flame from intensifying.

[0049] The heat insulation module includes a second cavity 14 opened on the storage frame 3. A heat insulation annular box 8 is fixedly installed inside the second cavity 14 and filled with liquid water. A first seal 6 for locking the heat insulation annular box 8 is fixedly installed on the top of the storage frame 3 by multiple screws. A water injection pipe 4 is fixedly installed on the storage frame 3 and is connected to the second cavity 14.

[0050] The heat-insulating annular box 8 is filled with liquid water. When the battery 2 burns, the heat of combustion will be absorbed by the water in the heat-insulating annular box 8. The top of the heat-insulating annular box 8 is equipped with a vent pipe. The heat generated by combustion will be absorbed by the water, causing the water to evaporate and be discharged from the vent pipe. Then, the vaporized water will be replenished through the water injection pipe 4.

[0051] Example 2: This example differs from Example 1 in that: (Refer to...) Figures 1-2 , Figures 4-13 The flame blocking module is used to block the open flame generated by the combustion of battery 2, preventing the open flame from shooting out and affecting the surrounding batteries 2. The flame blocking module consists of a partition package box 9. A pop-out component is installed between the partition package box 9 and the storage frame 3. When burning, the partition package box 9 will pop out from the storage frame 3.

[0052] A second seal 7 is welded to the top of the storage box 3 to secure the partitioned package box 9 and protect its internal components. The seal can be broken by the ejector assembly.

[0053] The pop-up component includes a first cavity 13 formed on the storage frame 3 and cooperating with the partition package box 9. Multiple hollow hydraulic telescopic tubes 24 are fixedly installed in the first cavity 13. The telescopic end of each hollow hydraulic telescopic tube 24 is fixedly connected to the partition package box 9. The hollow hydraulic telescopic tube 24 is connected to the second cavity 14.

[0054] When battery 2 burns, the pop-out component will be unlocked. At this time, the hollow hydraulic telescopic tube 24 will lose its locking restriction and will extend under the action of water pressure, which will drive the partition package box 9 to move, push open the second seal 7, and make the partition package box 9 extend out of the storage frame 3.

[0055] The partitioned packaging box 9 is equipped with a packaging assembly 10 for wrapping the burning battery 2;

[0056] The package assembly 10 includes a U-shaped storage cavity 16 opened on the partitioned package box 9. Airbags 12 are installed inside the longer sides of the storage cavity 16, and side baffles 11 that cooperate with the airbags 12 are slidably installed inside the shorter sides. A docking mechanism is installed at the ends of the two airbags 12, and the airbags 12 are connected to the hollow hydraulic telescopic tube 24.

[0057] As the partition box 9 pops out of the storage frame 3, the airbag 12 will also lose the restriction of the second seal 7 and can unfold freely. The water in the hollow hydraulic telescopic tube 24 will also cause the airbag 12 to expand. At the same time, after water is injected into the storage cavity 16, the side baffle 11 will also pop out from the storage cavity 16 due to the water injection, thus forming a package with the airbag 12 to wrap the battery 2.

[0058] The airbag 12 is coated with fire-retardant paint and is also made of flame-retardant material.

[0059] The docking mechanism includes a first docking strip 19 fixedly installed on one of the airbags 12, a second docking strip 20 fixedly installed on the other airbag 12, a plurality of locking blocks 21 fixedly installed on the first docking strip 19, and a plurality of elastic telescopic rods 23 that cooperate in pairs fixedly installed on the second docking strip 20. Each pair of elastic telescopic rods 23 has a locking hook 22 that cooperates with the locking block 21 fixedly installed at their telescopic ends.

[0060] Because the two airbags 12 are filled with water, they are heavy and will shake during transportation, causing gaps to appear at the joint of the two airbags 12. This allows flames to escape from the gaps. Therefore, a jointing mechanism is set up to seal the gaps.

[0061] As the two airbags 12 pop open, the first connecting strip 19 and the second connecting strip 20 will be spliced ​​together. Under the action of pressure, the hook 22 will be inserted into the block 21. Under the action of the elastic telescopic rod 23, the hook 22 and the block 21 will be engaged, and the seam will be sealed by the action of the first connecting strip 19 and the second connecting strip 20.

[0062] Furthermore, the partition box 9 is equipped with a heat-absorbing component and a water-spraying component. The heat-absorbing component is used to absorb the heat generated by combustion, and the water-spraying component is used to spray liquid onto the burning battery 2 to cool it down and extinguish the fire.

[0063] The heat-absorbing component includes a water-filling cavity 15 located inside the partitioned package 9, which is filled with liquid water.

[0064] When the water-filled cavity 15 is filled with water and the partition box 9 pops out, the water-filled cavity 15 rises, which can insulate a larger area of ​​heat and has a better heat insulation effect.

[0065] Meanwhile, the water injection chamber 15 is connected to an exhaust pipe for water evaporation and exhaust.

[0066] The water spray assembly includes multiple spray holes 17 opened on the inner wall of the partitioned package box 9. Each spray hole 17 is fixedly installed with a spray pipe. Each spray pipe passes through and extends into the storage cavity 16, and passes through the airbag 12 and communicates with the inside of the airbag 12. A heat conduction mechanism 18 is installed inside the storage frame 3, which cooperates with the heat insulation ring box 8. A locking structure is installed between the heat conduction mechanism 18 and the spray hole 17.

[0067] After the battery 2 burns, it generates a lot of heat, which will trigger the locking structure to unlock the restriction on the partition package box 9. After the partition package box 9 pops out, the spray hole 17 on the partition package box 9 is exposed from the first cavity 13. The water injected from the water injection pipe 4 will be sprayed out from the spray pipe on the spray hole 17 and sprayed onto the battery 2 inside the storage frame 3 to cool down and extinguish the fire.

[0068] The heat conduction mechanism 18 includes a bottom heat conduction plate 25 fixedly installed at the bottom of the storage frame 3. Multiple heat conduction rods 26 are fixedly installed on the bottom heat conduction plate 25. A side heat conduction plate 27 is fixedly installed on each of the two inner side walls of the storage frame 3. Each heat conduction rod 26 is evenly connected to the side heat conduction plates 27. Multiple heat conduction rods are fixedly installed on each side heat conduction plate 27. Each heat conduction plate penetrates and is inserted into the heat insulation annular box 8.

[0069] The locking structure includes multiple slide rods 31 that are slidably mounted on the side heat-conducting plate 27. A connecting rod 28 is fixedly mounted on the multiple slide rods 31. A plug 29 that mates with the corresponding spray hole 17 is fixedly mounted on each slide rod 31. A memory alloy spring 30 is fixedly mounted between each plug 29 and the corresponding side heat-conducting plate 27.

[0070] When battery 2 burns, it generates a large amount of heat. The heat is quickly conducted to the memory alloy spring 30 through the bottom heat-conducting plate 25, the heat-conducting rod 26, and the side heat-conducting plate 27. At this time, the memory alloy spring 30 will quickly respond and contract according to the temperature (the length of the memory alloy spring 30 at room temperature is greater than the length after heating. This is based on the characteristics of the memory alloy spring 30 and is a basic technology that will not be elaborated here). The contraction of the memory alloy spring 30 will drive the plug 29 to move, causing the plug 29 to be pulled out from the spray hole 17. The partition package box 9 will be freed from the restriction of the plug 29 and will pop out from the storage frame 3 under the action of water pressure.

[0071] The specific operating steps of this device are as follows:

[0072] When the battery 2 burns, it generates a lot of heat. The heat will be quickly conducted to the memory alloy spring 30 through the bottom heat conduction plate 25, the heat conduction rod 26 and the side heat conduction plate 27. At this time, the memory alloy spring 30 will quickly respond and contract according to the temperature. The contraction of the memory alloy spring 30 will drive the plug 29 to move, so that the plug 29 is pulled out from the liquid spray hole 17, and the partition package box 9 loses the restriction of the plug 29.

[0073] The hollow hydraulic telescopic tube 24 will extend under the action of water pressure, which will drive the partition package box 9 to move, push open the second seal 7, and make the partition package box 9 pop out from the storage frame 3.

[0074] As the partition box 9 pops out of the storage frame 3, the airbag 12 will also lose the restriction of the second seal 7 and can unfold freely. The water in the hollow hydraulic telescopic tube 24 will also cause the airbag 12 to expand. At the same time, after water is injected into the storage cavity 16, the side baffle 11 will also pop out from the storage cavity 16 due to the water injection, thus forming a package with the airbag 12 to wrap the battery 2.

[0075] As the two airbags 12 pop out, the first connecting strip 19 and the second connecting strip 20 will be spliced ​​together. Under the action of pressure, the hook 22 will be inserted into the block 21. Under the action of the elastic telescopic rod 23, the hook 22 and the block 21 will be engaged. Under the action of the first connecting strip 19 and the second connecting strip 20, the seam will be sealed.

[0076] After the partition package box 9 pops out, the spray hole 17 on the partition package box 9 is exposed from the first cavity 13. The water injected from the water injection pipe 4 will be sprayed out from the spray pipe on the spray hole 17 and sprayed onto the battery 2 inside the storage frame 3 to cool and extinguish the fire.

[0077] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
