The invention relates to the field of hatch covers, and discloses a square embedded watertight hatch cover. The hatch cover comprises a hatch, mounting plates are arranged on the outer surfaces of the two ends of the hatch, mounting bolts are arranged in the mounting plates in a penetrating mode, a sealing ring is arranged on the outer surface of the upper end of the hatch, and a protection mechanism is arranged on the surface of the inner side of the hatch. And a rotating mechanism is arranged on the outer surface of the upper end of the mounting plate. According to the square embedded watertight hatch cover, people can be prevented from sliding into a hatch accidentally through the protective net under the condition that the hatch cover is not closed, the prevention effect can be achieved, accidents are prevented, the situation that a rotating mechanism is broken due to overexertion in the using process is avoided, the hatch cover can be fixed conveniently, and fixation is firm; and the fixing mode is flexible, the structure is simple, the situation of the inner side of the hatch can be observed without opening the hatch cover, flexibility is achieved, and trouble is saved.
