[0024] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0025] See also Figures 1 to 6 As shown, this preferred embodiment provides a double-sided opening and closing hatch cover for a ship, which includes a cover frame 1 and a cover leaf 2.

[0026] Among them, the cover frame 1 and the cover leaf 2 are both made of a composite board 3, the composite board 3 includes carbon fiber layers 31 located on the inner and outer surfaces, and a PET filler 32 is arranged between the two carbon fiber layers 31 on the inner and outer surfaces. One side of the cover leaf 2 is connected to the cover frame 1 through a hinge 4, and a double-sided opening and closing handle 5 is arranged on the cover leaf 2. A locking block 6 that cooperates with the double-sided opening and closing handle 5 to lock is arranged on the inner wall of the cover frame 1.

[0027] Therefore, the ship's double-sided opening and closing hatch cover is made of carbon fiber and high-strength PET materials. The weight of the entire hatch cover is significantly reduced compared to the steel hatch cover. It has a simple structure, easy operation, reduced welded parts, ensured structural stability and sealing, and has a longer service life.

[0028] As an optional solution, the hinge 4 includes a fixed seat 41, a rotating page 42 and a connecting screw 43. The fixed seat 41 is fixed on the outer wall of the cover frame 1, the rotating page 42 is fixed on the outer wall of the cover leaf 2, the rotating page 42 and the connecting screw 43 are rotatably connected via a pin shaft, the connecting screw 43 is threadedly connected to the fixed seat 41, and the depth of the connecting screw 43 screwed into the fixed seat 41 is adjustable, so that the locking degree of the cover leaf 2 and the cover frame 1 is adjustable, thereby fully ensuring the sealing effect of the cover leaf 2 when closed.

[0029] As an optional solution, a sealing strip 7 in contact with the end edge of the cover frame 1 is provided on the cover leaf 2 to further improve the wind and rain tightness of the double-sided hatch cover for ships.

[0030] As an optional solution, the locking block 6 is wedge-shaped, so that the locking degree between the double-sided opening and closing handle 5 and the locking block 6 can be adjusted, and the adjustable hinge 4 is used to ensure that the double-sided opening and closing handle 5 can always be reliably matched with the locking block 6.

[0031] As an optional solution, a limiter 8 is provided between the inner wall of the cover frame 1 and the inner wall of the cover leaf 2, and the limiter 8 is used to limit the maximum opening angle of the cover leaf 2 and keep the cover leaf 2 at the maximum opening angle to facilitate maintaining a smooth state.

[0032] Furthermore, the maximum opening angle is 100° to 110°, and 105° is taken as an example here.

[0033] As an optional solution, the cover frame 1 and the cover leaf 2 are both rectangular, and four double-sided opening and closing handles 5 are provided, and the four double-sided opening and closing handles 5 are distributed in a cross shape.
