A rotating assembly is arranged inside the wall body 1, and the rotating assembly is used to assist the door body 2 to rotate;

[0024] Specifically, start the hydraulic cylinder 4 to drive the moving block 5 to slide. When the moving block 5 slides, it will drive the first transmission rod 7 to rotate. When the first transmission rod 7 rotates, it will drive the first fixing block 8 to rotate. At this time, the door body 2 rotates with the rotation of the first fixing block 8. When the door body 2 rotates, it will drive the second fixing block 9 to rotate. Further, the second transmission rod 10 rotates under the drive of the second fixing block 9. At the same time, the second rotating shaft 12 rotates under the drive of the door body 2. At this time, the first slider 13 slides under the drive of the second rotating shaft 12, and the door body 2 opens and closes inside the wall body 1. Face recognition is performed on visitors in front of the automatic locking waterproof and airtight door through the camera 22, and the opening or locking of the door body 2 is remotely controlled.

When the moving block 5 slides along the outer wall of the first guide rail 6 driven by the hydraulic cylinder 4, the moving block 5 will drive the first transmission rod 7 to rotate around the moving block 5. When the first transmission rod 7 rotates around the moving block 5 driven by the moving block 5, the first transmission rod 7 will drive the first fixing block 8 to rotate around the first transmission rod 7. At this time, the door body 2 rotates inside the wall body 1 following the rotation of the first fixing block 8. When the door body 2 rotates driven by the first fixing block 8, the door body 2 will drive the second fixing block 9 to rotate around the door body 2. Then, the second transmission rod 10 rotates around the first rotating shaft 11 driven by the second fixing block 9. At the same time, the second rotating shaft 12 rotates inside the first slider 13 driven by the door body 2. At this time, the first slider 13 slides inside the wall body 1 driven by the second rotating shaft 12. The door body 2 moves up and down while flipping, and the door body 2 opens and closes inside the wall body 1. The camera 22 performs face recognition on the visitors of the automatic locking waterproof and airtight door. After the terminal determines whether the visitors have access rights, it remotely controls the opening or locking of the door body 2, and finally realizes the purpose that the waterproof and airtight door can be automatically locked or opened without manual pushing, so as to achieve the effect of saving labor; start the electric push rod 15 to drive the push block 16 to move up and down. When the push block 16 moves up and down driven by the electric push rod 15, the push block 16 will drive the rotating plate 17 to rotate around the third rotating shaft 18. When the rotating plate 17 rotates around the third rotating shaft 18 driven by the push block 16, the rotating plate 17 will drive the second slider 20 to slide along the outer wall of the second guide rail 19. When the second slider 20 slides along the outer wall of the second guide rail 19 driven by the rotating plate 17, the second slider 20 will drive the clamping block 21 to move left and right. At this time, the clamping block 21 disengages from the inside of the camera 22, and finally realizes the purpose of quickly installing and disassembling the camera 22, so as to achieve the effect of maintaining and replacing the camera 22; it can not only achieve the effect of saving labor, but also achieve the effect of maintaining and replacing the camera 22.
