[0052] The ventilation mechanism 7 further comprises side boxes 709 fixedly installed on both sides of the cabinet body 2, a plurality of Z-shaped plates 710 are equidistantly arranged on the side boxes 709, and the plurality of Z-shaped plates 710 are rotationally connected with the side boxes 709, wherein the top of some of the Z-shaped plates 710 is fixedly connected with a gear two 711, the top of every two Z-shaped plates 710 is sleevedly installed with a belt 712, and the side surface of the gear two 711 is engaged with the ventilation rack 708;

[0053] In the embodiment, according to the two contacts 701 arranged at the top and the bottom of the frame body 514, the Z-shaped plates 710 on both sides of the cabinet body 2 are alternately opened according to the moving direction of the heat dissipation pipe 515 during heat dissipation, so that the flow rate of air is improved, and rapid cooling can be realized.

[0054] The use method and advantages of the present application are as follows:

[0055] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 , Figure 12 , Figure 13 ,

[0056] S1: when the internal temperature of the power distribution cabinet is high, the driving motor 502 and the air supply device 512 are started to run synchronously, the driving motor 502 arranged below the protective plate 8 drives the rotating disc 503 connected to the output shaft of the driving motor 502 to rotate, the transmission head 504 fixedly connected to the bottom end of the rotating disc 503 performs circular motion around the axis of the rotating disc 503, and the transmission head 504 slides in the sliding seat 505 when rotating, so as to generate a circular direction thrust, the thrust drives the sliding seat 505 to slide from one side to the other side at the top of the cabinet body 2, and the sliding seat 505 drives the transmission rod 508 and the heat dissipation pipe 515 to slide synchronously through the extension rod 506 connected to the bottom during the sliding process, the sliding process drives the air supply device 512 to slide from one end to the other end of the hanger 511 through the frame body 514, the adapter 509 connected to the top and the bottom of the heat dissipation pipe 515 slides from the bent hook to the flat part of the guide groove 518, in the process, the extension pipe 510 connected between the two turning pipes 513 is stretched outward, so as to facilitate normal air delivery, and air is delivered to the inside of the heat dissipation pipe 515 through the air supply device 512, the turning pipe 513 and the extension pipe 510;

[0057] S2: When the heat dissipation pipe 515 moves from the corner of the cabinet 2 to the front side of the components 3, the gear one 602 engaged with the track rack 601 rotates, and through the abutting of the spring sheet 604 with the abutting rod 603, the end of the abutting rod 603 is clamped in the gear slot 605, so that when the gear one 602 rotates, the adapter 509 below the heat dissipation pipe 515 is continuously rotated, and in turn drives the heat dissipation pipe 515 to rotate counterclockwise. When the heat dissipation pipe 515 rotates, the air dispersed from the through hole 516 can blow the dust on the components 3, and the moving direction of the heat dissipation pipe 515 is synchronized, so that the dust on the components 3 can be cleaned during the heat dissipation process. When the wheel disc 503 drives the transmission head 504 to rotate one hundred and eighty degrees, the transmission head 504 continues to move in a circle, so that the sliding seat 505 returns to the initial position, and the heat dissipation mechanism 5 returns as a whole. When the heat dissipation pipe 515 returns, the gear one 602 rotates in the opposite direction, and in the process, the abutting rod 603 does not clamp the gear slot 605, but rubs the surface of the gear slot 605 and frequently passes through, and compresses the spring sheet 604 by a distance, so that the heat dissipation pipe 515 does not rotate when returning, which can prevent the dust on the components 3 from being blown in the opposite direction, so that the dust dispersion does not occur, and the through hole 516 on the heat dissipation pipe 515 can make the air blow out directly to the components 3, further improving the heat dissipation effect of the components 3;

[0058] S3: While the cabinet 2 is being cooled, the sliding seat 505 drives the upper and lower contacts 701 to move synchronously through the frame 514. When the heat dissipation pipe 515 cools and blows the components 3 at the same time, the contact 701 moves above the frame 514, and the contact 701 contacts the surface of the baffle 706 and is resisted by the baffle 706. With the gradual movement of the frame 514, the upper contact 701 pushes the wedge-shaped rod 705 above the cabinet 2, so that the horizontal bar 703 compresses the spring one 704, and the upper horizontal bar 703 drives one of the ventilation racks 708 connected thereto to move synchronously, so that the ventilation rack 708 drives the gear two 711 to rotate. When the frame 514 moves to the end of the hanging rack 511, the upper contact 701 is separated from the inclined surface of the wedge-shaped rod 705, and when it returns, it passes through the other side of the wedge-shaped rod 705 and approaches the head of the hanging rack 511. When the wedge-shaped rod 705 is pushed by the hinged baffle 706, the spring two 707 is stretched. When the upper contact 701 is completely separated from the baffle 706, the baffle 706 is automatically returned to an inclined state under the action of the tension of the spring two 707;

[0059] S4: when the heat dissipation pipe 515 simultaneously performs heat dissipation and blowing operation, the upper horizontal strip 703 drives the ventilation rack 708 to move and drive the three gear two 711 to rotate synchronously, each group of Z-shaped plate 710 rotates synchronously through the belt 712, changes from the closed state to the open state, the dust blown down can be output to the inside of the cabinet 2, and the cabinet 2 is in a state of one side closed and one side open, which is convenient for taking away heat when dissipating heat and directly excluding heat outside the cabinet 2.

[0060] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the present application and are not intended to limit the present application.
