At the same time, the weather is now very changeable, which leads to a higher actual operating temperature of the equipment on site. This can easily affect the service life of the equipment and cause its stability to be greatly reduced.
[0003] To facilitate heat reduction in equipment, existing technologies typically install ventilation systems on mechanical equipment to facilitate heat exchange between the equipment and the external environment. However, most commonly used ventilation louvers in existing technologies have fixed blade angles, making it difficult to adjust the airflow according to the operating conditions of the mechanical equipment. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an adjustable ventilation louver door, which aims to solve the problem of ventilation regulation.
[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: An adjustable ventilation louver door includes a door body, with mounting openings at the upper and lower parts of the door body. Each mounting opening has multiple louvers arranged longitudinally, and both ends of each louver are rotatably connected to the two inner sides of the mounting opening via fixed shafts. Each end of each louver is fixedly provided with a sliding shaft, which is spaced apart from the fixed shaft. An arc-shaped sliding groove corresponding to each sliding shaft is provided on one inner side of the mounting opening, and the center of the arc-shaped sliding groove coincides with the axis of the fixed shaft. A drive cavity is provided in the side wall of the door body, and the arc-shaped sliding grooves are all connected to the drive cavity. A drive rod is slidably mounted up and down in the drive cavity. The sliding shafts pass through the arc-shaped sliding grooves and are rotatably connected to the drive rods. A rotation adjustment component is installed on one side of the door body, and the rotation adjustment component is connected to the drive rods via a transmission assembly to drive the drive rods to move up and down.
[0006] The beneficial effects of this utility model are: when the equipment operating temperature is too high, the louvers can be adjusted by rotating the adjusting component to increase the louver angle and increase the ventilation volume to remove the heat from the equipment; when there is rain outside or the equipment is not required to have as much air volume during winter operation and the room needs to be kept warm, the louver angle can be adjusted to prevent rain or ensure the temperature inside the room; the ventilation volume can be freely adjusted according to the equipment temperature requirements, and the operation is convenient.

[0018] Furthermore, a cover plate is fixedly sleeved on the sliding shaft, the cover plate slides against the inner side of the mounting opening, and the cover plate covers the arc-shaped sliding groove.
[0019] The beneficial effects of adopting the above-mentioned further solution are: the setting of the cover can seal the sliding groove, prevent external dust and debris from entering the drive cavity, and prevent debris accumulation from affecting the inside of the door.
[0020] Furthermore, the door body includes a door frame and a central beam. The two ends of the central beam are fixedly connected to the middle of the door frame. The mounting opening is formed between the central beam and the top of the door frame and between the central beam and the bottom of the door frame.
