The inner wall of the fixed frame 11 is provided with teeth meshing with the first gear 22. The bottom end of the first rotating rod 18 is connected to the belt 10. When the rotating column 9 drives the belt 10 to rotate, the moving frame 20 is driven to slide under the fixed frame 11, and the movement of the moving block 21 in the moving frame 20 is coordinated to drive the first rotating rod 18 to move back and forth around the inner wall of the fixed frame 11. The first blade 19 can be driven to rotate by the rolling of the first gear 22 on the teeth on the inner wall of the fixed frame 11, and then the heat dissipation work is performed toward different positions in the distribution cabinet body 1, and the heat dissipation efficiency is higher. A motor is installed at the bottom of the distribution cabinet body 1, and the output end of the motor on the distribution cabinet body 1 is connected to one of the rotating columns 9. When the motor is started, the first rotating rod 18 can automatically move back and forth around the inner wall of the fixed frame 11, and the rotation and heat dissipation function of the first blade 19 can be realized.

[0017] See also Figure 1-4, a second blowing chamber 16 is arranged on both sides of the first blowing chamber 8 in the lower wall of the power distribution cabinet body 1, and the two second blowing chambers 16 are separated from the first blowing chamber 8 by a partition 17, and a second fan blade 14 is arranged in the second blowing chamber 16, and an air outlet hood 6 is connected to the upper wall of the second blowing chamber 16, and an air outlet pipe 7 is connected to the top of the air outlet hood 6, and the air outlet pipe 7 is arranged on the inner side wall of the power distribution cabinet body 1, and a plurality of air outlet holes are opened on the air outlet pipe 7 along its length direction. When the second fan blade 14 rotates, the air outlet holes on the air outlet pipe 7 directly dissipate heat in the power distribution cabinet body 1, thereby further improving the heat dissipation efficiency, and a through groove 15 is opened on the partition 17, and a U-shaped strip 12 is movably arranged in the through groove 15, and the second blowing chamber The second rotating rod 13 is rotatably connected to the lower wall of 16, and the second fan blade 14 is arranged at the top of the second rotating rod 13. The U-shaped bar 12 extends to both sides of the second rotating rod 13. A second gear 24 is sleeved on the second rotating rod 13. Teeth are arranged on the inner walls on both sides of the U-shaped bar 12. By moving the U-shaped bar 12 in the through groove 15, the teeth on the inner walls on both sides of the U-shaped bar 12 alternately drive the second gear 24 to rotate, so as to drive the second fan blade 14 on the second rotating rod 13 to rotate in the same direction. A connecting rod 23 is connected to the side of the U-shaped bar 12, and one end of the connecting rod 23 is connected to the moving block 21.

[0018] The implementation principle of the power distribution cabinet with heat dissipation function in the embodiment of the present application is as follows: when it is necessary to dissipate heat inside the distribution cabinet body 1, first, the motor is directly started to drive the two rotating columns 9 and the belt 10 to rotate as a whole, so that the moving frame 20 slides back and forth on the fixed frame 11, and cooperates with the movement of the moving block 21 in the moving frame 20 to drive the first gear 22 on the first rotating rod 18 to roll on the inner wall of the fixed frame 11, and automatically drives the first fan blade 19 at the top of the first rotating rod 18 to blow air toward the distribution cabinet body 1, thereby Heat is dissipated at different positions in the distribution cabinet body 1 to improve the heat dissipation efficiency. The movement of the movable frame 20 and the movable block 21 drives the teeth on the inner walls on both sides of the U-shaped bar 12 to alternately drive the second gear 24 to rotate through the connecting rod 23, so as to drive the second rotating rod 13 and the second fan blade 14 to rotate in the same direction as a whole. The shunt generated when the second fan blade 14 rotates is blown out from the air outlet on the air outlet pipe 7 on the side wall of the distribution cabinet body 1, and the heat is directly dissipated in the distribution cabinet body 1, which further improves the heat dissipation efficiency. The structure is simple and the function is practical.
