[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] Example 1

The gas transmission component 2 includes a transfer chamber 21 fixedly connected to the top of the distribution cabinet body 1, and two conduits 22 are fixedly connected to the bottom of the transfer chamber 21, and the two conduits 22 are connected to the transfer chamber 21. The outer walls of the two conduits 22 are provided with a plurality of first through holes 23, and the outer walls of the two conduits 22 are provided with sleeves 24, and the outer wall of the sleeve 24 is provided with a plurality of second through holes 25, and the first through holes 23 are connected to the second through holes 25. The outer wall of the conduit 22 is provided with two limiting grooves 26, and limiting rings 27 are arranged in the two limiting grooves 26. The two limiting rings 27 are fixedly connected to the same sleeve 24, and the outer walls of the two sleeves 24 are fixedly connected to the same transmission structure 28, and the bottom end of the transmission structure 28 is transmission-connected to the output end of the servo motor 29.

[0028] The shape of the limiting groove 26 matches the shape of the limiting ring 27 . The transmission structure 28 is composed of three transmission wheels and a transmission belt, and the transmission wheel in the middle is transmission-connected to the output end of the servo motor 29 .

[0029] During use, after the airflow is input into the transfer chamber 21 through the heat dissipation component 3, the airflow will enter the two conduits 22 respectively and be discharged through the first through hole 23. During this process, the servo motor 29 can be started to drive the transmission wheel located in the middle of the transmission structure 28 to rotate, so that the transmission wheel drives two of the transmission wheels to rotate at the same time. Because the other two transmissions are arranged on the outside of the two sleeves 24, when the sleeve 24 rotates, the sleeve 24 will rotate in the limit groove 26 on the outside of the conduit 22 through the limit ring 27. As the sleeve 24 starts to rotate, the sleeve 2 The plurality of second through holes 25 on the outside will correspond to the first through holes 23 on the outside of the conduit 22, so that the airflow is discharged through the first through holes 23 and the second through holes 25. Since the second through holes 25 are arranged in a linear array, the airflow will be discharged gradually from high to bottom or from low to high, and finally the inside of the power distribution cabinet body 1 is cooled, which facilitates the gathering of the generated airflow and the orderly discharge, so that the discharged airflow will be stably discharged to the electronic components inside the power distribution cabinet body 1, avoiding energy waste and evenly distributing the generated airflow.

[0033] During use, the filter device 34 is docked with the positioning groove 33 above the distribution cabinet body 1 through the mounting plate 35. After the mounting plate 35 and the positioning groove 33 are completely docked, the mounting plate 35 can be locked in the positioning groove 33 with the help of bolts 36. When the fan 32 inside the conveying pipe 31 is started, the air drawn from the outside will first pass through the filter device 34, and then be input into the transfer chamber 21 after being filtered by the filter device 34, which facilitates the filtering of the drawn air through the filter device 34, and prevents impurities in the air from entering the distribution cabinet body 1 and causing damage to the electronic components inside the distribution cabinet body 1.
