hatch cover system and cargo ship

This invention belongs to the field of marine technology and discloses a hatch cover system and a cargo ship. The hatch cover system includes a hatch cover body rotatably mounted on the deck of the cargo ship, capable of rotating relative to the deck to switch between a covered state, a side enclosure state, and a deck extension state. In the covered state, the hatch cover body covers the upper part of the deck, thus covering the hatch opening of the cargo hold located below the deck. In the side enclosure state, the hatch cover body rotates to an angle with the deck, at which point it forms a side enclosure structure on the deck. In the deck extension state, the hatch cover body rotates to the outside of the cargo ship, at which point it can carry cargo. This hatch cover system can switch between multiple forms to function as a cover, a wall, and an extended deck area, improving functional integration and space utilization.
