[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figure 1-3 As shown, a battery charging protection cabinet includes a cabinet body 1. Inside the cabinet body 1, there is a fire extinguishing mechanism 2 and multiple charging chambers 3. The charging chambers 3 are evenly distributed on the left and right sides of the fire extinguishing mechanism 2. A heat dissipation mechanism 5 is provided in the middle of the upper side of the cabinet body 1. The heat dissipation mechanism 5 is connected to the multiple charging chambers 3. The fire extinguishing component is connected to the multiple charging chambers 3. The fire extinguishing mechanism 2 is electrically connected to the charging chambers 3.

[0020] In this embodiment, the heat dissipation mechanism 5 includes a fan 501, a main air duct 502, and multiple branch air ducts 503. The fan 501 is installed in the middle of the upper side of the cabinet 1. One side of the main air duct 502 is installed in the middle of the rear side of the cabinet 1. The rear output end of the fan 501 is located at the upper end of the main air duct 502. Multiple branch air ducts 503 are installed on the left and right sides of the main air duct 502. The branch air ducts 503 are connected to the charging compartment 3. A baffle 4 is provided on the upper part of the cabinet 1. The baffle 4 is located on the upper part of the fan 501. A filter 504 is provided at the front input end of the fan 501.

[0021] Specifically, the drive fan 501 delivers the low-temperature outside air filtered by the filter 504 into the charging chamber 3 through the main air duct 502 and the branch air duct 503 to dissipate heat from the charging battery and prevent the charging temperature from becoming too high, which could lead to danger.

[0022] In this embodiment, the fire extinguishing mechanism 2 includes a carbon dioxide cylinder 201, a connecting pipe 202, a main gas pipe 203, a branch gas pipe 204, a nozzle 205, a control cabinet, a solenoid valve, a sensor, and a controller. The control cabinet is located in the middle of the cabinet body 1, the controller is installed on the upper inner side of the control cabinet, and the sensor is installed on the top wall inside the charging compartment 3. The controller is electrically connected to the fan 501, the solenoid valve, and the sensor. The solenoid valve is installed in the middle of the connecting pipe 202, and one end of the connecting pipe 202 is connected to the carbon dioxide cylinder 201. At the output end, carbon dioxide cylinder 201 is installed on the bottom wall of the control cabinet. The other end of connecting pipe 202 is installed in front of main gas pipe 203.
