A handle 9 is provided on the sealing plate 8, and a positioning groove 10 is provided on one side of the handle 9. A sliding sleeve 11 is provided on the square channel 4 and is fixed to one side of the handle 9. A limiting plate 12 is slidably installed inside the sliding sleeve 11 and can be embedded in the positioning groove 10. An adjusting lever 13 is fixedly connected to the top of the limiting plate 12. A fixing plate 14 is provided on the square channel 4 and is located on the side of the sliding sleeve 11 away from the handle 9. One side of the fixing plate 14 is fixedly connected to... A guide rod 15 is provided, and the guide rod 15 is slidably installed between the guide rod 15 and the fixed plate 14. A compression spring 16 is fixed between the adjusting lever 13 and the fixed plate 14. During the ventilation of the transmitter room, when the incoming air passes through the filter screen 7, the assembled filter screen 7 filters and intercepts the dust and impurities contained in the incoming air to prevent external dirt from entering and accumulating in the room. Then, the dust-removed air is introduced into the transmitter room to ventilate and dissipate heat in the high-temperature transmitter room. When the filtration effect of the filter screen 7 is affected after long-term use, the adjusting lever 13 is pulled to drive the limiting insert plate 12 to slide in the sliding sleeve 11, so that the end of the limiting insert plate 12 is removed from the positioning groove 10.

This makes it convenient to disassemble and replace the filter screen 7, which is conducive to timely cleaning of the filter screen 7 and ensuring its filtration effect.

[0029] It is worth noting that in this embodiment, a sealing groove 17 is provided at the top of the square channel 4, and the sealing groove 17 matches the sealing plate 8. A sealing ring is provided in the sealing groove 17, and the sealing plate 8 can press the sealing ring to achieve a sealing effect. When reassembling the cleaned filter screen 7, the movable frame 6 is reinserted between the two sliding seats 5, so that the sealing plate 8 is embedded in the sealing groove 17 and presses the sealing ring. Then, the tensioned adjusting lever 13 is released. Guided by the fixing plate 14 and the guide rod 15, the compression spring 16 is reset to press the adjusting lever 13 by utilizing its reset function. The end of the limiting insert plate 12 is reinserted into the corresponding positioning groove 10 on the handle 9, thus completing the assembly of the filter screen 7.

The surfaces of the two connecting plates that are close to each other are fixedly connected with locking posts 27. The locking posts 27 can be locked into any of the locking slots 25. Since the outside of the vent 19 is exposed to the outside, rainwater and falling objects can easily enter the device through the vent 19, affecting the normal use of the ventilation device. Therefore, when ventilation is not performed, the shield 22 is closed into the mounting frame 21 to directly block the vent 19. When ventilation is performed on the machine room and it is raining, the shield 22 is deflected around the hinge to make the shield 22 in a specified tilt state. Then, the two support plates 24 are rotated so that the locking posts 27 are locked into the corresponding locking slots 25. The support plates 24 are used to support and fix the shield 22, ensuring that rainwater or falling objects fall on the tilted shield 22 to achieve a protective effect.
