[0021] See also Figure 1-5 The utility model provides an intelligent automatic mine air door, including a door frame 1, a damper 2 is arranged in the door frame 1, a cylinder 3 is rotatably provided on the upper outer wall of the door frame 1, a fixed shell 4 is fixedly connected to a corner of the front side wall of the damper 2, a column 5 is rotatably provided on the upper outer wall of the fixed shell 4, the output shaft of the cylinder 3 is fixedly connected to the column 5, a window 6 is provided on the damper 2, and a plurality of closing plates 7 are rotatably provided between the two side walls of the window 6. The damper 2 also has a receiving groove 21, an opening and closing mechanism 8 is provided in the receiving groove 21, and a linkage mechanism 9 is provided in the fixed shell 4.

[0022] Specifically, such as Figure 3 The worm gear 82 is rotated by the worm gear 83, and the worm gear 84 is rotated by the worm gear 82. The worm gear 84 is rotated by the worm gear 82, and the worm gear 84 is rotated by the worm gear 82. The worm gear 82 is rotated by the worm gear 83, and the worm gear 84 is rotated by the worm gear 82. The worm gear 82 is rotated by the worm gear 83, and the worm gear 84 is rotated by the worm gear 82. The worm gear 82 is rotated by the worm gear 82, and the driving rod 81 is rotated by the driving rod 81, so that the closing plate 7 is rotated. A passage is formed between the multiple closing plates 7 for pressure relief, thereby reducing the wind pressure resistance during the opening of the damper 2 and making the damper 2 open more smoothly.

[0023] Specifically, such as Figure 4 As shown, an intelligent automatic mine air door, the linkage mechanism 9 includes a follower rod 91, a first bevel gear 92, a transfer rod 93, a second bevel gear 94, a third bevel gear 95 and a fourth bevel gear 96. A follower rod 91 is rotatably provided on the inner wall of the lower side of the fixed shell 4, and the upper end of the follower rod 91 is fixedly connected to the column 5. A fixed sleeve is provided on the follower rod 91. A transfer rod 93 is also provided in the fixed shell 4.

[0026] It should be noted that the present invention is an intelligent automatic mine damper. During use, when the output shaft of the cylinder 3 is extended, the damper 2 will open. During the opening process, the column 5 will drive the follower rod 91 to rotate. The rotation of the follower rod 91 can make the first bevel gear 92 drive the second bevel gear 94 to rotate, thereby making the transfer rod 93 drive the third bevel gear 95 to rotate. The rotation of the third bevel gear 95 will drive the fourth bevel gear 96 to rotate, thereby making the rotating rod 83 rotate. When the rotating rod 83 rotates, it drives the worm 84 to rotate. The rotation of the worm 84 can make the worm gear 82 drive the driving rod 81 to rotate, so that the driving rod 81 drives the closing plate 7 to rotate, so that a passage is formed between the multiple closing plates 7 for pressure relief, thereby reducing the wind pressure resistance during the opening process of the damper 2, making the damper 2 open more smoothly. When the output shaft of the cylinder 3 is retracted, the damper 2 is closed, the column 5 is reversed, and after transmission, the closing plate 7 is reversed to close the window 6.
