The invention discloses a sealing device for a sliding watertight door. The sealing device comprises a sealing assembly and pressing mechanisms arranged on the door frame, wherein the sealing assembly comprises O-shaped sealing rings arranged on the surface of a door plank or the door frame and lip-shaped sealing rings arranged on the inner sides of the O-shaped sealing rings, the lip-shaped sealing rings are in a single opening lip shape, and lip openings face the center of the door plank. The pressing mechanisms comprise wedge-shaped blocks and pressing drive units. After the door plank is driven by a sliding drive unit in place in the sliding direction, the pressing drive units drive the wedge-shaped blocks to move so as to press the door plank to the door frame in the door plank pressing direction, and thus good double-face sealing of the watertight door is achieved through the independent separation operation of sliding and pressing, relative to the door frame, of the door plank, the requirement for evenly sealing the double faces of the watertight door can be met, meanwhile the problem that sealing performance is lowered due to wear to and the shape and mounting state change of the sealing piece caused by opening and closing of a watertight door is solved, and the requirements for the power of a power device and rigidity and strength of a drive device are lowered.
