Description

Technical Field

[0001] The utility model relates to the technical field of machine room exhaust, and more specifically to an exhaust device for a transmitter machine room. Background Art

[0002] Radio and television are the media that broadcast audio and video programs to a wide area through radio waves or wires. They are collectively called broadcasting. Broadcasting only for sound is called audio broadcasting; broadcasting for both sound and video is called television broadcasting. In a narrow sense, broadcasting is the use of radio waves and wires to transmit content only with sound. In a broad sense, broadcasting includes what we usually think of as sound-only broadcasting and television with both sound and video. Existing radio and television applications are already very widespread. For the equipment room of existing radio and television transmitters, there are many electrical equipment inside, and exhaust devices are needed for exhaust and ventilation.

[0003] When using existing exhaust devices, most of them use filters to filter dust in the air. Although most of the existing filters are detachable and can be easily cleaned, in order to improve the ventilation effect, the aperture of the filter is generally not set very small, so some fine dust will enter the inside of the exhaust device more or less. Due to the small space inside the exhaust hood, it is time-consuming and laborious to clean the dust, which affects the cleaning efficiency. At the same time, it is not convenient to clean the dust on the exhaust fan blades, so there are certain disadvantages in use.

[0004] In view of this, we propose an exhaust device for a transmitter room. Utility Model Content

[0027] See also Figure 1-4 ,The utility model provides a technical solution:

[0028] A ventilation device for a transmitter room, comprising an installation frame 1, an exhaust hood 4 is arranged on one side of the installation frame 1, and an air inlet hood 5 is arranged on the other side of the installation frame 1, a filter screen 6 is arranged on the outside of the air inlet hood 5, an exhaust fan 2 is arranged on the outside of the installation frame 1 located inside the air inlet hood 5, and two groups of sliders 9 are movably arranged on the inside of the installation frame 1, and mounting plates 10 are fixedly arranged on the outside of the two groups of sliders 9, and a clamping block 11 is fixedly arranged on the outside of the mounting plate 10, and a mounting groove 7 for docking the air inlet hood 5 is opened on the outside of the installation frame 1, and the air inlet hood 5 is movably plugged into the mounting groove 7, and clamping grooves 12 for docking the clamping block 11 are opened on both sides of the air inlet hood 5, and two groups of limit springs 13 are arranged on the inside of the installation frame 1, and one end of the two groups of limit springs 13 is respectively connected to the installation frame 1 on both sides, and the other end of the limit spring 13 is connected to the slider 9. The limit spring 13 does not deform in the initial state. When installing the air inlet cover 5, first press the handle 17 to drive the connecting rod 16 and the movable plate 14 to move. When the movable plate 14 moves, it drives the connecting plate 15 and the slider 9 to move. When the slider 9 moves, it squeezes the limit spring 13. At this time, the limit spring 13 is deformed. At this time, the air inlet cover 5 is inserted into the installation groove 7, and then the handle 17 is released. At this time, the elastic potential energy of the limit spring 13 is released, so that the slider 9 and the installation plate 10 can be driven to move. When the installation plate 10 moves, it drives the card block 11 to be stuck in the card slot 12 on the outside of the air inlet cover 5, so that the air inlet cover 5 can be easily and quickly loaded and unloaded.

[0029] Specifically, a through hole 3 is formed through the outer side of the installation frame 1. The through hole 3 can facilitate the circulation of air and improve the exhaust effect of the device.

[0030] Furthermore, a slide bar 8 is fixedly provided on the inner side of the installation frame 1 , and the slide bar 8 movably passes through the slider 9 . The slide bar 8 can limit the slider 9 , so that the slider 9 moves along the slide bar 8 , thereby improving the movement stability of the slider 9 .

[0031] It is worth mentioning that a movable plate 14 is movably provided on the inner side of the mounting frame 1, and connecting plates 15 are rotatably provided on both sides of the movable plate 14. The two groups of connecting plates 15 are rotatably connected to the two groups of sliders 9 respectively, and a connecting rod 16 is fixedly provided on the outer side of the movable plate 14. The connecting rod 16 movably penetrates the mounting frame 1 and extends to the outside, and a handle 17 is fixedly provided on the outer end of the connecting rod 16 at the outer part of the mounting frame 1. By pressing the handle 17, the mounting plate 10 and the block 11 can be conveniently driven to move, thereby improving the convenience of operation.

[0032] It is worth noting that a mounting block 18 is movably provided on the outside of the mounting frame 1, the exhaust fan 2 is fixedly installed on the outside of the mounting block 18, and a connecting block 19 is fixedly provided on the outside of the mounting block 18, and a movable block 20 is fixedly provided on the outside of the connecting block 19. By providing the mounting block 18, the exhaust fan 2 can be easily installed and the installation stability of the exhaust fan 2 is improved.

[0033] In addition, an electric push rod 21 is provided on the outside of the installation frame 1, one end of the electric push rod 21 is connected to the installation frame 1, and the other end of the electric push rod 21 is connected to the installation block 18. By turning on the electric push rod 21 through an external power supply, the installation block 18 and the exhaust fan 2 can be easily pushed to a suitable position, thereby making it more convenient to clean the exhaust fan 2 and further improving the convenience of cleaning.

[0034] It must be mentioned that multiple groups of support blocks 22 are rotatably arranged on the outer side of the mounting block 18, and T-blocks 23 are rotatably arranged on the outer side of the multiple groups of support blocks 22. Multiple groups of T-slots 24 for docking with the T-blocks 23 are provided on the outer side of the mounting frame 1. When the mounting block 18 moves, it drives the multiple groups of support blocks 22 to move, thereby further improving the stability of the exhaust fan 2.

[0035] Working principle: First, the filter 6 can filter the dust in the air. When some fine dust enters the inner side of the air inlet cover 5 and adheres to it, the handle 17 is pushed to drive the connecting rod 16 and the movable plate 14 to move. When the movable plate 14 moves, it can drive the connecting plate 15 to move. The connecting plate 15 drives the slider 9 to slide on the slide rod 8 and squeezes the limit spring 13. At the same time, the slider 9 moves to drive the mounting plate 10 and the block 11 to move. The block 11 moves out of the slot 12 on the outside of the air inlet cover 5. At this time, the air inlet cover 5 can be taken out of the mounting slot 7, so that the dust on the air inlet cover 5 and the filter 6 can be cleaned conveniently. At the same time, after the air inlet cover 5 is disassembled, the dust on the exhaust fan 2 can also be cleaned conveniently. It is very flexible and convenient to use.
