Description

Technical Field

[0001] This utility model relates to the field of marine technology, and more specifically, to a hatchback door device and a ship. Background Technology

[0002] Marine weatherproof steel doors play a vital role in ship safety, especially in adverse weather conditions. They effectively prevent seawater and rainwater from entering the cabin, ensuring the safety of the ship's internal equipment and personnel.

[0003] However, common marine weatherproof steel doors typically use hinges, resulting in a limited opening method—usually only opening to the left or right. In smaller vessels and in situations with unique spatial layouts, traditional left- or right-opening designs often occupy significant space due to the door's opening direction, making installation difficult or use inconvenient.

[0031] First Embodiment

[0032] Please refer to Figure 1The hatchback device 100 provided by this utility model is installed at the hatch opening 202 of the hull 200.

[0033] The hatchback assembly 100 includes a hatch 10 and a drive mechanism 20. The hatch 10 includes a first door panel 11 and a second door panel 12. The first door panel 11 and the second door panel 12 are fixedly connected and arranged at an angle. The end of the first door panel 11 away from the second door panel 12 is hinged to the top outer side of the hatch opening 202. The drive mechanism 20 is used to drive the first door panel 11 to rotate relative to the hull 200, so as to drive the second door panel 12 to close or open the hatch opening 202. A sealing element 30 is provided on the edge of the second door panel 12.

[0034] It is understood that in this embodiment, the cabin 201 includes a top wall. One end of the first door panel 11 is hinged to the outer side of the top wall. Specifically, a third hinge seat 13 is fixedly provided on the outer side of the top wall, and one end of the first door panel 11 is hinged to the third hinge seat 13. When the first door panel 11 rotates downward and fits against the outer side of the top wall, the second door panel 12 closes the hatch opening 202. When the first door panel 11 rotates upward, the second door panel 12 gradually moves away from the hatch opening 202, thereby opening the hatch door 10.

[0035] It is understood that the inner side of the second door panel 12 refers to the side of the second door panel 12 facing the interior of the cabin 201. The outer side of the second door panel 12 refers to the side of the second door panel 12 facing the exterior of the cabin 201.

[0036] By providing a seal 30 at the edge of the second door panel 12, when the hatch 10 is closed, the edge of the second door panel 12 abuts against the side wall of the hatch 10 opening. The seal 30 is located between the second door panel 12 and the side wall of the hatch 10 opening, thereby sealing off the cabin 201 and preventing wind and rain from entering.

[0037] Specifically, the drive mechanism 20 includes a drive cylinder 21, a first hinge seat 22, and a second hinge seat 23. The first hinge seat 22 is fixedly mounted on the top inner side of the hatch 202. The second hinge seat 23 is fixed on the inner side of the second door panel 12. The two ends of the drive cylinder 21 are hinged to the first hinge seat 22 and the second hinge seat 23, respectively. It can be understood that when the hatch 10 needs to be opened, the drive cylinder 21 extends, pushing out the second door panel 12, causing the hatch 10 to flip upwards. When the drive cylinder 21 is fully extended, it supports the hatch 10, lifting it up and thus opening the hatch 10. When the hatch 10 needs to be closed, the drive cylinder 21 retracts, sequentially pulling the second door panel 12 and the first door panel 11 downwards. When the second door panel 12 abuts against the side wall of the hatch 10 opening, the hatch 10 is closed. It is understood that the drive cylinder 21 in this embodiment can not only drive the hatch 10 to rotate relative to the hull 200, but also support the hatch 10 to prevent it from falling and injuring the crew after it is lifted.

[0038] In detail, in this embodiment, the maximum rotation angle of the first door panel 11 and the second door panel 12 relative to the hull 200 is 80°-90°.

[0039] Please refer to Figure 2 Specifically, the sealing element 30 is a sealing strip. One end of the sealing strip is embedded in the edge of the second door panel 12. Specifically, in this embodiment, the sealing strip is disposed on the first side of the second door panel 12 away from the first door panel 11, and on the second and third sides connected to both ends of the first side. It should be noted that the sealing strip is made of an elastic material, and at the connection between the first side and the second and third sides, the sealing strip is bent to form a corner.

[0040] Furthermore, the edge of the second door panel 12 is provided with a groove. A strip-shaped protrusion 31 is provided on the sealing strip. The strip-shaped protrusion 31 is embedded in the groove. Specifically, the strip-shaped protrusion 31 can be glued to the groove.

[0041] In this embodiment, when the hatch 10 is closed, the first door panel 11 is abutted against the top of the hatch 202. The second door panel 12 is inclined toward the outside of the hatch 202. It is understood that in this embodiment, the hatch 10 is installed on the ship, and when the ship encounters rain, rainwater can flow down the outside of the second door panel 12 to the deck of the ship.

[0042] Furthermore, a handle is provided on the outer side of the second door panel 12. Specifically, in this embodiment, the handle is installed at the end of the second door panel 12 away from the first door panel 11. It is understood that in the event of an emergency and the drive cylinder 21 fails, the handle can be used to open the hatch 10 to rescue personnel inside the cabin 201.

[0043] To further enhance the sealing performance of the hatch 10, a pressing mechanism is also provided on the second door plate 12. When the hatch 10 is closed, the pressing mechanism is used to press the second door plate 12 against the hatch opening 202. Specifically, the pressing mechanism can be a spring. The spring force presses the second door plate 12 against the hatch opening 202. Optionally, the pressing mechanism can also be a cylinder or similar structure, which applies pressure towards the interior of the cabin 201 to the second door plate 12. This invention does not limit the specific structure of the pressing mechanism.

[0044] The beneficial effects of the liftgate device 100 provided in this embodiment of the present invention include:

[0045] The hatchback device 100 of this utility model is disposed at the hatch opening 202 of the hull 200, and includes a hatch 10 and a drive mechanism 20. The hatch 10 includes a first door panel 11 and a second door panel 12. The first door panel 11 and the second door panel 12 are fixedly connected and set at an included angle. The end of the first door panel 11 away from the second door panel 12 is hinged to the top outer side of the hatch opening 202. The drive mechanism 20 is used to drive the first door panel 11 to rotate relative to the hull 200, so as to drive the second door panel 12 to close or open the hatch opening 202. A sealing element 30 is provided on the edge of the second door panel 12. The hatchback device 100 of this utility model opens the hatch 10 by hinged first door panel 11 to the top of the hatch opening 202 and the drive mechanism 20 pushes the hatch 10 to rotate relative to the top of the hatch opening 202; or the drive mechanism 20 pulls the hatch 10 to rotate relative to the top of the hatch opening 202, so as to close the hatch 10 by tilting it downward. The hatchback door device 100 of this utility model adopts an upward opening method, which occupies a relatively small space of about 10 in the hatch.
