The invention discloses a watertight hatch cover structure. The watertight hatch cover structure is characterized in that the watertight hatch cover structure comprises an outer peripheral plate and an inner plate body; the inner plate body is of a double-layer structure and comprises a first plate and a second plate; the watertight hatch cover structure further comprises an inner plate main bodyferrule; the main body ferrule comprises an isolation gasket embedded between the first plate and the second plate; a first upper sealing ring on the isolation gasket extends towards the direction ofthe first plate; a second lower sealing ring on the isolation gasket extends towards the direction of the second plate; a notch is formed in the side, close to the inner plate body, of the peripheralplate; and the main body ferrule is exactly embedded into the notch. The watertight hatch cover comprises an outer peripheral plate ferrule and the inner plate main body ferrule; and the sealing performance of the hatch cover is guaranteed through a multi-layer sealing structure.
