[0052] The rainproof cover 7 is cone-shaped and completely covers the low-voltage distribution cabinet body 1 to ensure that the low-voltage distribution cabinet is completely covered, thereby achieving rain and snow protection for the low-voltage distribution cabinet.

[0053] The air guide module 9 includes a connecting pipe 901 fixedly connected to the upper end of the inner shell 102. The left and right ends of the connecting pipe 901 are connected to the corresponding air inlet holes 105.

[0056] The air supply unit 64 is connected to the energy storage box 4 to draw the external cold air into the square box 6501. After being drawn into the square box 6501, the cold air will pass through a number of cold air control units 6503 arranged at equal intervals. When the cold air passes through the cold air control unit 6503, the guide plate 65033 installed in the concave frame 65032 will disperse and guide the cold air, and the cold air will cause the barrier block 65034 to shake in the process of passing through the adjacent guide plate 65033. The shaking of the barrier block 65034 will convert the speed of the cold air movement into the energy of the shaking of the barrier block 65034, so that the cold air The speed of air movement is reduced, and the barrier block 65034 during shaking will collide with the debris in the cold air, causing the debris to fall into the square box 6501 under the collision. In the process of decelerating the cold air, the debris in the cold air is also blocked to prevent the debris from accumulating in the round hole on the stripping sheet 6505, thereby causing the stripping sheet 6505 to fail to work, thereby increasing the working time of the stripping sheet 6505; after being decelerated and stripped by the cold air control unit 6503, the cold air will pass through the debris stripping component 6504. When the cold air passes through the debris stripping component 6504, the guide rod 65044 will disperse and guide the cold air to the adjacent diversion sheet 65042, and flow in the cavity between the diversion sheet 65042 and the guide plate 65041. When the cold air flows in the space between the adjacent diversion sheet 65042, the diversion sheet 65042 and the guide plate 65041, the blocking rod 65043 will block the cold air and perform several dispersion guides, so that the speed of the cold air will be reduced again after being decelerated by the guide sheet 65033, and the nylon line 65045 installed on the wall of the adjacent diversion sheet 65042 will be connected with the nylon line 65045 installed on the wall of the guide plate 65041 and the diversion sheet 65042. The nylon wire 65045 will form a dense stripping network wire to block and strip the debris in the cold air, ensuring that the proportion of debris in the cold air drawn into the low-voltage distribution cabinet body 1 is reduced to a minimum, and the components in the low-voltage distribution cabinet body 1 are cooled by the stripped cold air. The drawn cold air is discharged from the exhaust hole after cooling the components in the low-voltage distribution cabinet body 1, so as to achieve the purpose of cooling the distribution cabinet, to prevent debris from accumulating in the round hole on the stripping sheet 6505, thereby causing the stripping sheet 6505 to fail to work, and then to increase the working time of the stripping sheet 6505, so that the distribution cabinet can be cooled normally;

[0057] When encountering rainy and snowy weather, the rainproof cover 7 blocks the rain and snow to ensure that the low-voltage distribution cabinet is completely covered, thereby achieving rain and snow protection for the low-voltage distribution cabinet; when the low-voltage distribution cabinet body 1 is hit during outdoor use, the buffer spring 104 buffers the external collision force, thereby improving the protection of the internal components of the low-voltage distribution cabinet and greatly improving the protection performance of the low-voltage distribution cabinet.
