[0002] With the increasing popularity of electric vehicles, battery swapping cabinets, as centralized battery charging and storage facilities, are intelligent devices that provide rapid battery replacement services for electric vehicles. They are mainly used in shared mobility, logistics and delivery, and other fields. Users can place depleted batteries into the cabinet by scanning a code or swiping a card and retrieve fully charged batteries. The entire process takes only tens of seconds to a few minutes, greatly improving vehicle usage efficiency.
[0003] Fire prevention and control has become a challenge for the industry. When lithium batteries experience thermal runaway, traditional fire-fighting methods are insufficient. They cannot detect the internal condition of the battery compartment in a timely manner. At the same time, fire extinguishers can only suppress open flames and cannot quickly reduce the internal temperature of the battery cells, resulting in a high rate of reignition. Therefore, we have made improvements and proposed an active immersion water fire-fighting device for the battery swapping cabinet compartment. Utility Model Content

[0027] like Figure 1-4 As shown, this embodiment proposes an active immersion water fire-fighting device for the battery swapping cabinet, including a battery swapping cabinet body 1, a cabinet door 2 on the outside of the battery swapping cabinet body 1, a battery compartment 3 in the middle of the battery swapping cabinet body 1, a fire-fighting component 5 on one side of the battery swapping cabinet body 1, and a control box 6 on the upper end of the fire-fighting component 5.
[0028] The fire protection component 5 includes a liquid storage tank 51 fixed to one side of the main body 1 of the battery swapping cabinet, an inlet pipe 52 installed on the upper end of the liquid storage tank 51, a liquid level sensor 53 and a water pump 54, a water pump 55 connected to the input end of the water pump 54, a water supply pipe 56 connected to the output end of the water pump 54, an inner pipe 57 connected to the end of the water supply pipe 56, a solenoid valve 58 installed on the outside of the inner pipe 57, a sprinkler head 59, and a fire detector 511 installed inside the main body 1 of the battery swapping cabinet.
[0029] Support legs 4 are fixedly installed at the bottom corner of the battery swapping cabinet body 1. There are four sets of support legs 4 arranged in an array. A touch screen is installed on the outside of the battery swapping cabinet body 1, which facilitates the support of the battery swapping cabinet body 1 and the opening of the cabinet door 2.
[0030] The number of battery compartments 3 is several and they are arranged in an array. The number of cabinet doors 2 and battery compartments 3 is equal, and hinges and locks are installed between them to facilitate the connection between cabinet doors 2 and battery compartments 3, ensuring that batteries can be stored inside battery compartments 3.
[0031] The liquid storage tank 51 is connected to the main body 1 of the battery swapping cabinet by bolts. The liquid inlet pipe 52 is connected to the liquid storage tank 51 and is also connected to the external liquid supply pipe. The liquid storage tank 51 can be supplied with immersion liquid. At the same time, the liquid level can be detected by the liquid level sensor 53. When the liquid level is low, the liquid can be supplied through the external liquid supply pipe.
[0032] The control box 6 contains a control circuit board and a battery. The control circuit board also contains a remote control module and a communication module. The water pump 54 is electrically connected to the control circuit board, which facilitates the supply of liquid to the water supply pipe 56 and the inner pipe 57.
[0033] The number of internal pipes 57 is equal to the number of battery compartments 3, and the internal pipes 57 are connected to the water supply pipe 56.

[0034] In summary, the working principle of this utility model is as follows:
[0035] During use, the fire detector 511 detects the fire situation inside the battery compartment 3, and then the fire-fighting component 5 immerses water into the interior of the battery compartment 3 to actively immerse the interior space of the battery compartment 3, so as to isolate oxygen and cool it down.
[0036] It should be noted that, through the setting of the fire protection component 5, when any one of the temperature sensor, smoke detector, and VOC sensor in the fire detector 511 detects a fire in one of the battery packs in the battery compartment 3, it feeds back to the control circuit board. The control circuit board then activates the corresponding solenoid valve 58 and starts the water pump 54. The water pump 54 then connects the immersion liquid (water and inhibitor) inside the storage tank 51 to the corresponding compartment pipe 57 through the water supply pipe 56 via the water pump pipe 55. This allows the immersion liquid to be sprayed through the corresponding sprinkler head 59 until the battery pack inside the battery compartment 3 is submerged. The stored immersion liquid is then automatically released and directly floods the corresponding battery compartment 3 through the compartment pipe 57 to isolate oxygen and cool it down. This allows for timely detection of the internal condition of the battery compartment 3, rapid reduction of the internal temperature of the battery cells, low reignition rate, and improved practicality of the device.
