[0025] Example 1:

[0026] like Figure 1 , 2As shown in Figure 4, a hatch cover for a ship is characterized in that it includes a cofferdam 17 and a cover plate 2. A hinge 3 and an opening and closing assembly are provided on one side of the cofferdam 17. The two ends of the hinge 3 are respectively fixed to the cofferdam 17 and the cover plate 2. The cover plate 2 is provided with two locking holes on the side away from the hinge 3. Two locking assemblies corresponding to the locking holes are provided inside the cover plate 2. The locking assemblies are used to lock the cover plate 2 to the cofferdam 17.

[0027] like Figure 3 As shown, the opening and closing assembly includes a winch 9, a wheel bracket 8, and a lifting rope 6. The wheel bracket 8 is equipped with a pulley system 7. One end of the lifting rope 6 is wound around the winch 9, and the other end of the lifting rope 6 passes over the pulley system 7 and is equipped with a hook 5. The hook 5 hooks the lifting rod 4, and the lifting rod 4 is fixed to the cover plate 2. The operator only needs to crank the winch 9 to pull the lifting rope 6 through the pulley system 7, thereby flipping and opening the cover plate 2.

[0028] The ship hatch cover of this utility model adopts an opening and closing assembly, which enables the operator to quickly and conveniently lift the cover plate 2. With the help of the locking assembly and locking hole, the cover plate 2 can be locked to the enclosure plate 17 by rotating the rotating shaft 13. The operation is convenient and the opening and closing efficiency is high. In addition, the sealing gasket 18 is added to the edge of the enclosure plate 17 and the cover plate 2 to ensure good sealing performance.

[0029] The locking assembly includes two fixing units and a connecting rod 15. The connecting rod 15 connects the two fixing units. The four fixing units are evenly distributed around the cover plate 2. Each fixing unit includes a pull rod 11. Both ends of the pull rod 11 are hinged to rotating rods 12. The rotating rods 12 are hinged to the cover plate 2. The end of the rotating rod 12 is provided with a locking block 14. The locking block 14 cooperates with a wedge. The wedge is set inside the enclosure 17. A rotating shaft 13 is rotatably connected in the locking hole. The rotating shaft 13 is fixedly connected to the rotating rod 12. A sleeve can be fitted on the top of the rotating shaft 13 to facilitate the operator to rotate the rotating shaft 13. The rotation of the rotating shaft 13 drives the rotating rod 12 to rotate, so that the locking block 14 is locked into the wedge. The locking blocks 14 in other positions are driven by the linkage of the connecting rod 15 and the pull rod 11.

[0030] A limiting bracket 10 is provided on one side of the enclosure 17. A locking bolt 19 is provided at the top of the limiting bracket 10. The locking bolt 19 is used to lock the cover plate 2. The locking bolt 19 is a screw bolt, which is convenient for the operator to rotate and adjust the position, and can also lock the pressure plate on the edge of the cover plate 2 to limit the opening of the cover plate 2.

[0031] like Figure 5 As shown, a reinforcing plate 1 is provided on the outer side of the enclosure 17, the enclosure 17 is fitted with the edge of the cover plate 2, and a sealing gasket 18 is provided on the edge of the cover plate 2, the sealing gasket 18 is attached to the enclosure 17.

[0032] The top of the wheel assembly bracket 8 is provided with a clamp 16; the clamp 16 can guide the movement of the lifting rope 6 and ensure that the contact part between the pulley assembly 7 and the lifting rope 6 is always free, so as to avoid the lifting rope 6 from being worn more rapidly due to the change of the flip angle of the cover plate 2.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
