A passive delay hatch unlocking mechanism suitable for an underwater environment comprises a hatch cover, a dry cabin shell, a wet cabin shell, a hatch cover fixing ring, a hatch cover sealing ring, a hatch cover sealing pressing plate, a water-soluble fixing belt, a radial sealing ring, an axial sealing ring, a hatch cover fixing ring bolt and a hatch cover sealing ring bolt. The invention has the following characteristics: (1) based on the characteristic that the water-soluble fixing band is dissolved in water, the passive delayed unlocking of the hatch in the underwater environment can be realized; and (2) rigid connection between the hatch cover and the shell can be realized through a sandwich structure formed by the hatch cover, the hatch cover fixing ring, the water-soluble fixing belt and the hatch cover fixing ring bolt.
