[0001] The utility model relates to the technical field of battery safety, in particular to an active fire-fighting explosion-proof backup power supply cabinet with a battery box capable of being quickly disassembled. Background Art

[0002] In order to ensure the safe and stable operation of industrial power supply, the main power supply cabinet is often equipped with a backup power supply cabinet to maintain uninterrupted power supply operation when the main power supply cabinet fails. The main power supply cabinet is generally equipped with a complete fire alarm device, and accordingly, the cost of the main power supply cabinet has also risen a lot. If the backup power supply cabinet is also equipped with the same fire alarm device as the main power supply cabinet, it is easy to cause the cost of the entire set of equipment to be too high and lose the market competitive advantage. In addition, the frequency of use of the backup power supply cabinet is much lower than that of the main power supply cabinet, and the fire hazards it faces are also greatly reduced. There is no strong need to configure the best fire alarm device.

[0003] Therefore, there is an urgent need in the art for a backup power supply cabinet that ensures safe and stable operation without bringing unnecessary cost pressure to the entire machine. Summary of the invention

[0004] In order to overcome the defects of the prior art, the technical problem to be solved by the utility model is: how to configure a fire warning device with a simple structure, timely response and reasonable cost for a backup power supply cabinet.

[0006] The cabinet door is hinged on the cabinet body;

[0007] The battery pack is one or more, and all are detachably fixed to the battery rack in the cabinet by buckles;

[0008] The detector is one or more and all are arranged inside the cabinet;

[0009] The battery management unit is arranged inside the cabinet, and one or more detectors are respectively connected to the battery management unit via a communication harness;

[0010] The alarm device is embedded on the outer wall of the cabinet door and is also connected to the battery management unit through a communication harness;

[0011] The high-pressure water mist fire extinguishing device is arranged outside the cabinet.

[0012] On the basis of the above technical solution, the present invention can also be improved as follows.

[0013] Preferably, a shelf is provided on the outer wall of the cabinet, and the high-pressure fine water mist fire extinguishing device is placed on the shelf.

[0014] Preferably, a small cart is provided, and the high-pressure fine water mist fire extinguishing device is placed in the small cart.

[0015] Preferably, the detector is one or a combination of a CO detector, a VOC gas detector, a pressure detector, and a temperature detector.

[0016] Preferably, the detector is installed on the inner wall of the cabinet, or outside the battery pack.

[0017] Preferably, the alarm device is an indicator colored light and / or a loudspeaker.

[0018] Preferably, the high-pressure water mist fire extinguishing device comprises a water tank and a water mist fire pump, and the water mist fire pump draws water from the water tank to extinguish the fire.

[0019] Preferably, the high-pressure water mist fire extinguishing device further comprises a water adding mechanism, which is connected to the water tank and is used to replenish water for fire extinguishing.

[0020] Compared with the prior art, the utility model can produce the following beneficial technical effects:

[0021] The utility model uses the battery pack as a protection unit, arranges detectors in the battery cabinet to detect the concentration and temperature of combustible gases, and is equipped with a movable high-pressure fine water mist fire extinguishing device in the backup power supply workspace. Once the battery pack is thermally runaway, the detector transmits the alarm signal to the battery management unit, and the battery management unit performs graded sound and light alarms based on the received data. After the staff discovers the alarm situation, they quickly remove the out-of-control battery pack and connect the high-pressure fine water mist fire extinguishing device based on the alarm level to determine whether there is enough time and to ensure the safety of personnel. The high-pressure fine water mist quickly cools down the battery pack and extinguishes the fire through the pipeline; and it can continue for a long time to prevent the battery pack from reigniting.
