[0032] The following combination Figure 1-Figure 6 The present invention provides a battery fire extinguishing and transporting device, which is arranged under the battery rack of the battery swap station and is used to transport and fire-fight the batteries that have thermal runaway in the battery swap station. When the battery in the battery swap station has thermal runaway, the stacker transfers the thermal runaway battery to the transporting device for fire-fighting treatment to prevent a larger fire or explosion from occurring, which increases the uncontrollability of the accident.

[0033] The transfer device includes at least two bracket fixing components 1, and the two bracket fixing components 1 are respectively fixedly arranged on two opposite brackets of the battery rack 10 of the battery swap station. Each bracket fixing component 1 includes a driving mechanism 11, a driving shaft 12, at least one support hand 13 and at least one guide block 14. The guide block 14 is fixedly connected to the battery rack 10, and the support hand 13 is slidably connected to the guide block 14 and is sleeved on the driving shaft 12. The supporting portion 131 of the support hand 13 is used to connect the fire-fighting bracket 2; the driving mechanism 11 can drive the driving shaft 12 to move, drive the support hand 13 to slide relative to the guide block 14, and realize the detachable connection between the support hand 13 and the guide block 14.

[0034] The fire-fighting bracket 2 is detachably connected to the bracket fixing assembly 1 via a support handle 13 and is used to carry a thermal runaway battery.

[0035] The transfer mechanism 3 is arranged below the fire-fighting bracket 2 and is used for fire-fighting treatment of the thermal runaway battery.

[0036] This embodiment includes two bracket fixing assemblies 1, which are respectively fixed under two opposite brackets of the battery rack 10 through the housing of the driving mechanism 11 and the guide block 14. Figure 2 As shown, two spaced apart supporting hands 13 and two guide blocks 14 are sleeved on the driving shaft 12 of each bracket fixing assembly 1, and the supporting portion 131 of the supporting hand 13 extends to the inner side of the battery rack 10 to connect with the fire fighting bracket 2. The output end of the driving mechanism 1 is connected to the driving shaft 12, and by controlling the extension and contraction of the driving mechanism 11, the driving shaft 12 can be driven to move, thereby driving the supporting hand 13 to slide along the guide block 14. When the supporting hand 13 is separated from the guide block 14, the fire fighting bracket 2 falls downward into the transfer mechanism 3, and the transfer mechanism 3 safely transfers the fire fighting bracket 2 carrying the thermal runaway battery to the designated fire fighting treatment area.

[0037] When a battery has thermal runaway, the stacker transfers the thermal runaway battery to the fire-fighting bracket 2, controls the drive mechanism 11 to drive the drive shaft 12 to move, and then drives the handle 13 to slide along the guide block 14 until it is separated from the guide block 14, and the fire-fighting bracket 2 and the thermal runaway battery fall downward into the transfer mechanism 3, and the fire-fighting bracket 2 carrying the thermal runaway battery is safely transferred from the battery rack to the designated fire-fighting treatment area through the transfer mechanism 3. In the fire-fighting treatment area, professional fire-fighting equipment can be used to cool down and extinguish the thermal runaway battery until the battery state is stable and no longer poses a threat.

[0038] The bracket fixing assembly 1 of this embodiment realizes the rapid and reliable connection and separation of the fire-fighting bracket 2 through the combined design of the driving mechanism 11, the driving shaft 12, the support hand 13 and the guide block 14. Through the cooperation of the fire-fighting bracket 2 and the transfer mechanism 3, the rapid and safe transfer and fire-fighting treatment of the thermal runaway battery are realized. The transfer device can quickly respond to the thermal runaway battery event, safely transfer the battery from the battery rack and carry out fire-fighting treatment, effectively preventing the occurrence of dangerous situations such as fire or explosion, and has a high degree of flexibility and versatility, and can adapt to the transportation needs of thermal runaway batteries of different models and sizes.

[0039] Furthermore, the support handle 13 includes a T-shaped sliding portion 132, and the guide block 14 includes a slide groove 141 matched therewith, and the T-shaped sliding portion 132 is slidably connected to the slide groove 141. The cross section of the T-shaped sliding portion 132 is T-shaped, which matches the shape of the slide groove 141 provided on the guide block 14. The T-shaped sliding portion 132 can slide smoothly in the slide groove 141, and can maintain a certain stability to prevent shaking or falling off during the sliding process. When the fire-fighting bracket 2 needs to be connected, the T-shaped sliding portion 132 is completely embedded in the slide groove 141, and is in close contact with the bottom of the slide groove 141 to form a stable connection structure.

[0040] The supporting portion 131 of the support handle 13 extends to one side and is connected to the connecting beam 211 of the fire-fighting bracket 2, thereby effectively supporting and fixing the fire-fighting bracket 2. In some possible embodiments, the supporting portion 131 is provided with a rubber pad for increasing the friction between the supporting portion 131 and the connecting beam 211, which improves the contact tightness and stability between the supporting portion 131 and the connecting beam 211 through its inherent elasticity and friction characteristics. In another possible embodiment, a magnetized pad is provided on the supporting portion 131. The magnetized pad is magnetized so that the supporting portion 131 and the connecting beam 211 can generate magnetic attraction when in contact, thereby further enhancing the stability of the connection and facilitating separation.

[0041] Furthermore, the driving mechanism 11 is an electric push rod, and the telescopic stroke of the electric push rod matches the sliding distance of the handle 13, so that the handle 13 can be moved to a predetermined position to achieve connection or separation with the fire bracket 2. The telescopic stroke of the electric push rod in this embodiment can be precisely controlled to ensure that the handle 13 can be accurately moved to a predetermined position to achieve stable connection or separation with the fire bracket 2. The maintenance cost is low, and it is easy to integrate into existing battery swap stations and battery racks. The movement of the electric push rod is smooth and impact-free, which reduces the potential risk of damage to the fire bracket 2 and the battery pack and improves overall safety.

[0042] In some other possible implementations, the driving mechanism 11 may also be configured as a driving structure such as a pneumatic push rod, a hydraulic push rod, or a servo motor with a lead screw transmission.

[0043] Furthermore, the fire-fighting bracket 2 includes a rectangular upper support frame 21, a lower bearing frame 22, and four vertically arranged pillars 23, and the pillars 23 are used to connect the support frame 21 and the bearing frame 22;

[0044] The supporting frame 21 includes two parallel connecting beams 211 , and the connecting beams 211 are detachably connected to the support handle 13 .

[0045] like Figure 3 As shown, the fire-fighting bracket 2 of this embodiment is composed of two parallel connecting beams 211 and corresponding lateral supports to form a stable rectangular structure. The connecting beam 211 not only provides sufficient strength and rigidity, but is also detachably connected to the support handle 13. In a possible embodiment, the lower surface of the connecting beam 211 is provided with a connecting block for connecting to the support handle 13 to facilitate the connection of a small-sized fire-fighting bracket with the bracket fixing assembly. The lower load-bearing frame 22 can be a rectangular frame for directly supporting the battery pack. In some possible embodiments, it can also be configured to include a plurality of parallel and intersecting cross beams and longitudinal beams to form a solid grid-like structure to provide sufficient load-bearing capacity and stability.

[0046] In this embodiment, the fire-fighting bracket 2 forms a stable and rigid structure through the combination of the rectangular upper support frame 21, the lower load-bearing frame 22 and the vertical support 23, which can safely carry and transport the battery pack. The detachable connection between the connecting beam 211 and the support handle 13 enables the fire-fighting bracket 2 to be quickly connected or separated from the transport system, thereby improving the transport efficiency. The overall structure of the fire-fighting bracket takes into account the safety and stability of the battery pack, and can prevent the battery pack from falling off or being damaged during transportation.

[0047] Furthermore, a plurality of support members 221 are provided on the carrier 22, and the support members 221 are block-shaped structures protruding from the surface of the carrier 22. In one possible embodiment, the support members 221 may be elastic support structures, such as rubber, springs, etc., provided on the surface of the carrier 22, so as to absorb and disperse vibration energy during transportation and protect the battery pack from damage. In another possible embodiment, the support members 221 may be support structures with adjustable height or position, such as being connected to the carrier through threaded connections, sliding connections or other adjustable mechanisms, so as to adjust the height and position according to the specifications of the battery pack to be carried.

[0048] In this embodiment, a plurality of support members 221 are provided on the carrier 22. By providing a plurality of evenly distributed support points, the support members 221 can reduce the direct contact area between the battery pack and the carrier 22, thereby reducing wear and friction, improving the stability of the battery pack during transportation in the fire-fighting bracket 2, and reducing the impact of shaking, tilting, vibration and impact.

[0049] Furthermore, an angled joint frame 24 is provided between the support frame 21 and the pillar 23 to prevent interference with the bracket fixing assembly 1 during movement or installation.

[0050] In this embodiment, the bracket fixing component 2 is arranged under the bracket of the battery rack. The connecting beam 211 close to the bracket is easy to interfere with the bracket fixing component 2 during movement or installation. The setting of the bevel joint frame 24 makes the connecting beam 211 and the support 23 not directly connected at a right angle, but form a certain bevel angle, thereby effectively preventing the fire-fighting bracket 2 from interfering with the bracket fixing component 1 during movement or installation.

[0051] The provision of the angled joint frame 24 adjusts and optimizes the structure of the fire-fighting bracket 2, making it highly adaptable and making the installation and dropping process smoother.

[0052] Furthermore, the transfer mechanism 3 includes a fire extinguishing box 31 and a transfer bracket 32 ​​arranged below the fire extinguishing box 31. Figure 4 shown.

[0053] The fire fighting box 31 is arranged below the fire fighting bracket 2, and is used to carry the fallen fire fighting bracket 2 and the thermal failure battery. The fire fighting box 31 can be made of high-strength, corrosion-resistant materials, such as stainless steel or galvanized steel plate, and the size of the box is larger than the fire fighting bracket 2.

[0054] Furthermore, the transfer bracket 32 ​​includes a base frame 321 and a push handle frame 322 , and the push handle frame 322 is connected to a side frame of the base frame 321 .

[0055] The base frame 321 of the transfer bracket 32 ​​is used to carry the fire box 31. In a possible implementation, the base frame 321 is connected to the fire box 31 by a clamping structure or welding. The push handle 322 is connected to a side frame of the base frame 321 to facilitate pushing. The base frame 321 can be welded with steel pipes or profiles. The setting of the transfer bracket 32 ​​makes the transportation of the fire box 31 more convenient and faster, and improves the emergency response speed.

[0056] Furthermore, a drainage assembly 311 is provided at the bottom of the fire extinguishing box 31. The drainage assembly 311 is provided at the bottom of the fire extinguishing box 31 and is used to discharge the accumulated water in the box after the fire extinguishing operation. In a possible embodiment, the drainage assembly 311 includes a drainage hole and a drainage valve provided at the bottom of the fire extinguishing box 31. The position and number of the drainage holes are set according to the size and shape of the fire extinguishing box 31 to ensure the drainage effect.

[0057] Furthermore, a limit block 323 is provided below the base frame 321, and a limiting structure 101 cooperating therewith is provided on a side frame parallel to the pushing direction of the battery rack 10 and the transfer bracket 32. In this embodiment, a limit block 323 is provided below the base frame 321 to limit the position of the transfer mechanism 3 entering the battery rack during the pushing process. When the transfer bracket 32 ​​is pushed under the battery rack 10, the limit block 323 abuts against the limiting structure 101 to prevent the transfer mechanism 3 from moving excessively and causing collision and damage to other structures, thereby improving the reliability of the entire transfer device.

[0058] The base frame 321 is a solid grid structure including a plurality of parallel and intersecting cross beams and longitudinal beams to provide sufficient load-bearing capacity and stability. A plurality of casters are provided at the bottom of the base frame 321 for movement and transportation of the transport bracket 32.

[0059] Furthermore, a ground rail 5 is provided at the bottom of the transfer device to provide guidance for the movement of the casters when pushing the transfer bracket.

[0060] In this embodiment, the fire-fighting bracket 2 is suspended above the transfer mechanism 3 by the support handle when not carrying the thermally failed battery; when the stacker transfers the thermally failed battery to the fire-fighting bracket 2, the bracket fixing component 1 is controlled to separate the support handle from the fire-fighting bracket 2, and the fire-fighting bracket 2 and the thermally failed battery fall into the fire-fighting box 31 of the transfer mechanism 3; the transfer mechanism 3 and the thermally failed battery are transferred to the fire-fighting treatment area. The fire-fighting box 31 can be filled with water to extinguish the thermally failed battery; after the battery is extinguished, the drainage valve of the drainage component is opened to drain the water and take out the battery; the fire is extinguished.
