A second rotating rod 10 is bolted to the middle of the second rotating wheel 9, and the second rotating rod 10 also extends to the inside of the sound insulation box 1.

[0032] It should be noted that the transmission system composed of the first rotating wheel 7, the rotating belt 8 and the second rotating wheel 9 ensures the synchronous rotation of the first rotating rod 6 and the second rotating rod 10, thereby improving the uniformity and efficiency of heat dissipation.

[0033] In this embodiment, the diameter of the second rotary rod 10 is consistent with that of the first rotary rod 6 and both are rotatably connected to the two side walls of the sound insulation box 1 via bearings. The first rotary rod 6 and the middle part of the first ventilation plate 2 are symmetrically distributed in the horizontal direction, and the second rotary rod 10 and the middle part of the second ventilation plate 3 are symmetrically distributed in the horizontal direction.

[0034] It should be noted that the staggered distribution design of the first rotating rod 6 and the second rotating rod 10 effectively avoids the problem of reduced heat dissipation caused by the two fans 13 blowing against each other, thereby ensuring the heat dissipation effect.

[0035] In this embodiment, the second rotary rod 10 and the first rotary rod 6 are both provided with threads on the outside and the threads are in opposite directions.

[0041] Working principle:

[0042] The first rotary rod 6 is driven to rotate by the motor 5, and the second rotary rod 10 is rotated together with the first rotating wheel 7, the rotating belt 8 and the second rotating wheel 9. The two movable boxes 11 threadedly connected to the first rotary rod 6 and the second rotary rod 10 move horizontally under the guiding action of the rail 14, and the small motor 12 in the movable box 11 drives the fan 13 to rotate to perform mobile heat dissipation inside the sound insulation box 1. Since the threads of the first rotary rod 6 and the second rotary rod 10 are in opposite directions, the two movable boxes 11 will only approach or move away from each other and will not move together, thereby reducing the possibility of the two fans 13 blowing against each other and causing a decrease in heat dissipation. At the same time, since the middle parts of the first rotary rod 6 and the second rotary rod 10 are respectively facing the first ventilation plate 2 and the second ventilation plate 3, combined with the design of the sound insulation plate and the Z-shaped ventilation hole 201, the noise generated by the opening during ventilation is further reduced while ensuring ventilation.

[0044] The soundproof cover is provided with a first rotating rod 6 driven by a motor 5 inside, and the first rotating rod 6 is linked with the second rotating rod 10 through the first rotating wheel 7, the rotating belt 8 and the second rotating wheel 9 to ensure synchronous rotation. The first rotating rod 6 and the second rotating rod 10 are provided with reverse threads on the outside, and the two movable boxes 11 threadedly connected with them can approach or move away from each other under the guidance of the rail 14, and the first rotating rod 6 and the second rotating rod 10 are staggered, which is conducive to avoiding mutual blowing and poor heat dissipation. The small motor 12 inside the two movable boxes 11 drives the fan 13 to rotate to effectively dissipate heat. In addition, the ventilation assembly of the soundproof cover is composed of a first ventilation plate 2 and a second ventilation plate 3, which are respectively located on the front and rear sides of the soundproof box 1, and are provided with Z-shaped ventilation holes 201 inside. With the design of the soundproof plate, the ventilation and heat dissipation requirements are guaranteed, and the noise transmission is reduced.
