When the lifting assembly 3 drives the door body 2 to move along the chute 11, the filling medium in the liquid cavity 41 is discharged, so that a gap exists between the sealing expansion sleeve 4 and the outer wall of the door frame 1, and the interaction force between the sealing expansion sleeve 4 and the door body 2 is reduced. While the contact assembly 5 protrudes out of the receiving groove 21, the contact assembly 5 reduces friction between the door body 2 and the sealing expansion sleeve 4 during the movement of the door body 2. When the lifting assembly 3 drives the door body 2 to move to the position that the door body 2 closes to block water flow, the contact assembly 5 is retracted into the accommodating groove 21. And at this time, the liquid cavity 41 of the sealing expansion sleeve 4 is filled with filling medium, so that the sealing expansion sleeve 4 is expanded, and the sealing expansion sleeve 4 is tightly attached between the outer wall of the door frame 1 and the inner wall of the chute 11. When the door body 2 blocks water flow, the sealing expansion sleeve 4 is expanded and filled between the door body 2 and the sliding groove 11, and gaps between the door body 2 and the sliding groove 11 are sealed, so that the sealing performance of the steel gate is improved.
