To meet the battery swapping requirements, a large number of battery packs are also stored inside the battery swapping station. During the charging and discharging process of the battery packs, thermal runaway problems may occur, and in severe cases, it may cause the combustion and explosion of the battery packs. Due to the high energy density and large power consumption of the battery swapping station, if fire protection measures are not taken in time, it will cause huge losses to the entire battery swapping station and surrounding facilities, and even endanger the safety of nearby vehicles and personnel.

[0038] As shown in the appendix Figure 1As shown in the figure, the fire protection system proposed by the present utility model for a battery swapping station includes at least one gas pipeline 10 and at least one water pipeline 20. The gas pipeline 10 is used to circulate a fire protection gas medium, and the water pipeline 20 is used to circulate a fire protection liquid medium. Combining with the attached Figure 2 , the gas pipeline 10 is used to connect with a storage device 30 arranged in the battery storage area 40. At least a fire protection medium matching one battery storage area 40 is stored in the storage device 30. The storage device 30 can transport the fire protection gas medium into the gas pipeline 10. The gas pipeline 10 is used to release the fire protection gas medium into the battery storage area 40. The water pipeline 20 is used to connect with a water storage device. The water storage device stores a fire protection liquid medium. The water storage device can transport the fire protection liquid medium into the water pipeline 20. The water pipeline 20 is used to release the fire protection liquid medium into the battery storage area 40.

[0039] Among them, power batteries are stored in the above-mentioned battery storage area 40.

[0040] By setting the gas pipeline 10, the gas pipeline 10 can release the fire protection gas medium into the battery storage area 40. The fire protection gas medium can absorb a large amount of heat and can effectively reduce the oxygen concentration and hydrogen concentration in the battery storage area 40, which is beneficial to improving the flame retardant and fire extinguishing efficiency. By setting the water pipeline 20, the water pipeline 20 can cooperate with the gas pipeline 10 to conduct fire protection treatment on the battery storage area 40, with high fire extinguishing efficiency. Especially when the gas pipeline 10 fails, the fire situation in the battery storage area 40 can be reduced by the fire protection liquid medium. The storage device 30 connected to the gas pipeline 10 stores a fire protection medium matching at least one battery storage area 40, which can not only ensure the fire extinguishing treatment of the gas pipeline 10 on at least one battery storage area 40, but also reduce the space occupation of the storage device 30. The overall structure is simple, easy to install and arrange, and has strong reliability.

[0041] When the number of battery storage areas 40 is greater than the storage capacity of the fire protection medium in the storage device 30, the gas pipeline 10 can be preferentially used to conduct fire protection treatment on the battery storage area 40. When fires occur in multiple battery storage areas 40, the water pipeline 20 serves as a supplement to the gas pipeline 10 to conduct fire extinguishing treatment on the battery storage area 40.

[0042] In an alternative solution, a fire extinguishing medium with halogen elements as the main chemical composition elements is stored in the storage device 30. At normal temperature and pressure, it is in a liquid state in the storage device 30 and becomes gaseous after release and is delivered into the battery storage area 40 through the gas pipeline 10. This fire extinguishing medium can react with oxygen and hydrogen elements to form relatively stable halides, thereby interrupting the combustion chain reaction and achieving effective fire extinguishing. Compared with the prior art where aerosol is used to isolate oxygen for fire protection, the fire extinguishing ability is stronger and more efficient, improving the fire protection reliability. Optionally, gas fire extinguishing agents such as heptafluoropropane and perfluoromethyl isopropyl ketone are stored in the storage device 30.

[0043] In an alternative solution, in combination with the attached Figure 1 and the attached Figure 2 , the gas pipeline 10 includes a first connection section 11 and a first functional section 12.

The master control valve 31 is used to control the opening or closing of the storage device 30. A sub-control valve 13 is provided on the first connection section 11. The sub-control valve 13 cooperates with the master control valve 31 to realize the on-off between the storage device 30 and the first functional section 12. When the master control valve 31 and the sub-control valve 13 are both opened, the fire extinguishing medium in the storage device 30 can be transported to the first functional section 12 and then released into the battery storage area 40.

[0046] In an alternative solution, a monitoring component is provided in the battery storage area 40. The monitoring component is communicatively connected to the master control valve 31 and the sub-control valve 13. When the monitoring component detects a fire, the master control valve 31 is opened, and the sub-control valve 13 on the gas pipeline 10 of the corresponding battery storage area 40 is opened to transport the fire extinguishing medium into the battery storage area 40 where the fire breaks out to extinguish the fire.

Through the arrangement of the first spray parts 14, the fire protection gas medium can be evenly released in the battery storage area 40, enabling the fire protection gas medium to quickly fill the battery storage area 40 to ensure the fire extinguishing efficiency.

[0049] In an alternative solution, as shown in the appendix Figure 1 As shown, the water pipeline 20 includes a second connection section 21 and a second functional section 22. The second connection section 21 is communicated with the second functional section 22. The second connection section 21 is used to connect to the water storage device.

[0055] In an alternative solution, in combination with the attached Figure 3 figure and the attached Figure 4 figure, the fixing component includes a first fixing part 51. The first fixing part 51 includes a supporting part 511 and first connecting parts 512 located at both ends of the supporting part 511.

The supporting part 511 includes a supporting groove that cooperates with the gas pipeline 10 or the water pipeline 20. The gas pipeline 10 or the water pipeline 20 can be partially accommodated in the supporting groove, so that the supporting part 511 fits with the gas pipeline 10 or the water pipeline 20. The supporting part 511 is used to support and hold the gas pipeline 10 or the water pipeline 20. The first connecting part 512 is installed in the battery storage area 40 through a first locking part 513.

[0056] Optionally, a screw hole is provided on the first connecting part 512, and the first locking part 513 is set as a fixing bolt, and the first connecting part 512 is fixedly installed in the battery storage area 40 by screwing.

[0057] Optionally, the supporting part 511 and the first connecting part 512 are integrally formed.

[0058] Optionally, the gas pipeline 10 is installed in the battery storage area 40 through the first fixing part 51.

[0059] In an alternative solution, as shown in the attached Figure 4As shown, the fixing component includes a second fixing portion 52.

[0062] Optionally, the water pipeline 20 is installed in the battery storage area 40 through the second fixing portion 52. Since the fire-fighting liquid medium flows in the water pipeline 20, the weight-bearing of the water pipeline 20 is relatively large. The second fixing portion 52 can play a good role in fixing the water pipeline 20, preventing the water pipeline 20 from shaking or generating abnormal noises during the flow of the fire-fighting liquid medium, and ensuring the stable and firm installation of the water pipeline 20.

[0063] Optionally, the second spraying portion 23 is installed in the battery storage area 40 through the first fixing portion 51.
