Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of hatch cover for ship, concretely is a double -sided open and close weather tight hatch cover. BACKGROUND

[0002] The weather tight hatch cover is a device installed at the opening of the cargo hold or other cabin of a ship, and its main function is to ensure that the hatch can maintain weather tightness during navigation, especially in adverse weather conditions such as wind, rain and sea waves, so as to prevent external moisture and other adverse environmental factors from entering the cabin, thereby protecting the cargo, equipment and ship structure in the cabin from damage.

[0003] For example, the existing Chinese patent (CN116534186A) discloses a hatch cover, which comprises a fence, a cylinder cover, a sealing assembly, a rotary ring and a locking assembly. The cylinder cover is detachably connected to the fence. The sealing assembly comprises a sealing strip, which is arranged on the cylinder cover. The rotary ring is sleeved on the outer peripheral surface of the fence, and the rotary ring is provided with a pressing piece. The locking assembly is connected with the rotary ring and is used to drive the rotary ring to move relative to the fence. The fence has a first position and a second position. When the rotary ring moves to the first position, the pressing piece abuts against the top end of the cylinder cover to apply a pre-tightening force to the sealing strip, so that the sealing strip is in close contact with the top end of the fence. When the rotary ring moves to the second position, the pressing piece is separated from the cylinder cover. In the present invention, the cylinder cover is closed, and the pressing piece on the rotary ring abuts against the top end of the cylinder cover to apply a pre-tightening force to the sealing strip, thereby ensuring the sealing of the cylinder cover. When the cylinder cover is reversely pressurized, the cylinder cover can withstand the internal pressure without deformation or separation from the fence due to the abutment of the pressing piece.

[0004] The above technical solution provides a one-way opening and closing hatch cover, i.e. only the opening and closing of the hatch cover can be performed from the outside. However, when the internal space of the ship is limited or personnel need to approach the hatch from different directions, the one-way opening and closing hatch cover cannot meet the needs of personnel entering and exiting. Therefore, a double-sided opening and closing weather tight hatch cover is provided. UTILITY MODEL CONTENTS
