The invention relates to a watertight door lock device. The watertight door lock device comprises a rotating hand wheel. The rotating hand wheel and a gear are coaxially fixed, and the rotating hand wheel drives the gear to rotate. The gear is hinged to a pair of connecting rods II. The connecting rods II are hinged to connecting rods I respectively. The connecting rod I on the left side and the connecting rod I on the right side are each hinged to a plurality of dog bodies. The lower portion of the connecting rod I on the left side and the upper portion of the connecting rod I on the right side are hinged to connecting rods IV through connecting rods III respectively. The connecting rods IV are provided with fixing rotating shafts. The connecting rods IV are hinged to connecting rods V, the connecting rods V are hinged to connecting rods VI, and the connecting rods VI are horizontal and are hinged to the dog bodies located at the upper portion and the lower portion of a watertight door. The connecting rods II, the connecting rods I, the connecting rods III, the connecting rods IV, the connecting rods V and the connecting rods VI are in central symmetry with the circle center of the gear as the center. The rotating hand wheel drives the gear to rotate, and the gear drives the connecting rods II, the connecting rods I, the connecting rods III, the connecting rods IV, the connecting rods V and the connecting rods VI to synchronously rotate, so the dog bodies on the periphery of the watertight door and wedge iron are pressed and locked.
