A cabinet door 2 is provided on one side of the cabinet 1. The cabinet door 2 is provided with a plurality of rectangular through holes. An explosion-proof observation window is embedded in the rectangular through hole. The explosion-proof observation window is made of explosion-proof glass. The explosion-proof glass has high strength and Impact resistance, can break into small particles when an explosion occurs to reduce harm to the human body, explosion-proof glass also has good light transmittance and fire resistance. The cabinet door 2 is rotatably connected to the cabinet body 1 by a hinge for easy opening and closing. The cabinet body 1 is provided with a plurality of partitions, which divide the interior of the cabinet body 1 into a plurality of independent charging compartments. An aerosol nozzle 6 is provided on one side of the inner wall of each charging compartment. The aerosol nozzle 6 can release a fire extinguishing agent to quickly extinguish the flame and suppress the occurrence of an explosion. A charging device is provided in the charging compartment.

[0020] The inner wall of the cabinet 1 is provided with a temperature detector 10. Usually, the temperature detector 10 is arranged at the center of the inner wall of the cabinet 1 so as to more accurately monitor the temperature change inside the entire cabinet. The bottom of the inner wall of the cabinet 1 is provided with an aerosol storage device 7. The aerosol storage device 7 includes: an aerosol storage tank, in which an aerosol fire extinguishing agent is stored. A heat dissipation device 8 is arranged on one side of the aerosol storage device 7. The heat dissipation device 8 is connected to the inner wall and the outer wall of the cabinet 1 so as to quickly dissipate heat when necessary to prevent the cabinet 1 from being overheated and causing a dangerous situation. The aerosol storage device 7 is provided with a heat dissipation device 8. The device 7 is connected to the aerosol nozzle 6 in each charging bin through an aerosol delivery pipe, and the aerosol delivery pipe is arranged in the cabinet 1. This delivery pipe is responsible for transporting the aerosol fire extinguishing agent from the storage device to the aerosol nozzle 6 in each charging bin. A solenoid valve is provided between the aerosol delivery pipe and the aerosol storage device 7. The solenoid valve is controlled by the display controller 4. When the system detects a fire or explosion risk, the display controller 4 will immediately instruct the solenoid valve to open, quickly release the aerosol fire extinguishing agent, and spray it into each charging bin through the aerosol nozzle 6, so as to quickly extinguish the flame and suppress the occurrence of explosion.

[0021] A flame detector 5 is provided at the top of the inner wall of the cabinet 1. The flame detector 5 is an ultraviolet flame detector. The ultraviolet flame detector can keenly detect the ultraviolet rays generated when the battery explodes, so as to find the fire source in time. This design can ensure that a quick response can be made in the early stage of the fire to avoid the fire from spreading. A push switch 3 is provided on the outer wall of the cabinet 1. The push switch 3 controls the overall working state of the charging cabinet. The user can turn on or off the charging cabinet by pressing the switch 3. A display controller 4 is provided on one side of the push switch 3.

[0022] The display controller 4 includes: a display and a central processing unit. The cabinet 1 is provided with an audible and visual alarm 13, which is connected to the central processing unit. When the system detects an abnormal situation, the audible and visual alarm 13 will be immediately activated, emitting a high-decibel alarm sound and flashing lights to attract people's attention as quickly as possible. The central processing unit is responsible for acquiring and processing data from the temperature detector 10 and the flame detector 5. When the value of the temperature detector 10 reaches a set threshold, the central processing unit will start the heat dissipation device 8 to dissipate heat in the internal space of the cabinet 1 to prevent the temperature from continuing to rise; When the values ​​of the temperature detector 10 and the flame detector 5 reach the set threshold at the same time, the display controller 4 will immediately open the solenoid valve between the aerosol delivery pipeline and the aerosol storage device 7, so that the aerosol fire extinguishing agent is quickly sprayed out through the aerosol nozzle 6 to extinguish the flame. At the same time, the display controller 4 will also start the sound and light alarm 13, sending out obvious sound and light alarm signals to remind users and surrounding personnel to pay attention and take corresponding emergency measures.

[0023] The charging device includes: an illumination device 9, a power supply device 11 and a charging matrix 12. The illumination device 9 is arranged on the inner wall of the charging bin to provide illumination so that the user can clearly see the situation inside the charging bin even in low light conditions. The power supply device 11 is connected to the charging matrix 12 and is responsible for providing stable electric energy to the charging matrix 12. The power supply device 11 is connected to the central processing unit. The power supply device 11 controls its power-on time and power-on state through the central processing unit. The central processing unit can flexibly adjust the working state of the power supply device 11 according to actual needs. The charging matrix 12 includes: a high-power AC to DC power supply and a plurality of battery charging seats. The high-power AC to DC power supply is connected to the charging matrix 12 and is responsible for providing stable electric energy to the charging matrix 12. The power supply device 11 is connected to the central processing unit. The power supply device 11 controls its power-on time and power-on state through the central processing unit. The central processing unit can flexibly adjust the working state of the power supply device 11 according to actual needs. The high-rate AC-to-DC power supply is responsible for converting the input 220V mains power into 12V DC power and transmitting it to each battery charging station. Each battery charging station can work independently. The modular design not only improves the charging efficiency, but also facilitates maintenance and replacement. The power supply device 11 is provided with a leakage protector and an air switch. The leakage protector can quickly cut off the power supply when a leakage is detected to prevent electric shock accidents. The air switch can automatically trip when the current is too large to protect the circuit and equipment from damage. The display can display the working status of the power supply device 11 in the charging compartment and the temperature information in the cabinet 1 in real time, so that the user can understand the working status of the charging cabinet at any time.

[0024] The following is a detailed introduction to the actual working scenario of a fireproof and explosion-proof automatic charging cabinet.

[0025] Under normal working conditions, the user turns on the charging cabinet by pressing the switch 3, the display controller 4 starts, the central processing unit begins to monitor the temperature and flame detection conditions inside the cabinet 1, the power supply device 11 provides stable power to the charging matrix 12 under the control of the central processing unit, and the lighting device 9 lights up to provide the user with sufficient light for convenient viewing and operation.

[0026] As the charging process proceeds, the temperature detector 10 monitors the temperature changes inside the cabinet 1 in real time. When the temperature in the cabinet 1 exceeds the set threshold, the central processor will immediately start the heat dissipation device 8 to quickly reduce the temperature inside the cabinet 1 through the heat dissipation device 8 to prevent safety hazards caused by overheating.

[0027] If a battery suddenly explodes during charging, the flame detector 5 will immediately detect the generated ultraviolet rays and transmit the signal to the central processor. The central processor will respond quickly, opening the solenoid valve between the aerosol delivery pipeline and the aerosol storage device 7, so that the aerosol fire extinguishing agent is quickly ejected through the aerosol nozzle 6 to extinguish the flame and suppress the occurrence of the explosion. At the same time, the sound and light alarm 13 is activated, emitting a high-decibel alarm sound and flashing lights to alert users and surrounding personnel.
