[0044] Embodiment 1

[0045] This embodiment provides a hatch cover device, which is configured to be arranged at the hatch of a hull, such as Figures 1 to 4 As shown, it can prevent the hatch from being blocked, avoid affecting the loading and unloading of cargo, ensure work efficiency and the safety of staff, and ensure that large-sized cargo can enter the cargo hold smoothly to avoid bumps and damage.

[0046] like Figures 2 to 4As shown, the hatch cover device includes a containment assembly 1 and a cover assembly 2. Among them, the containment assembly 1 is arranged on the hull, and the containment assembly 1 includes a containment frame 11 and two support frames 12. The containment frame 11 is arranged around the hatch along the circumference of the hatch, and the upper end of the containment frame 11 is higher than the hatch. By setting the containment frame 11, water can be prevented from entering the cargo hold, thereby preventing the cargo in the cargo hold from being soaked and damaged by water, and providing an installation basis for setting the cover assembly 2. The two support frames 12 are arranged on both sides of the containment frame 11 along the width direction of the hull, and one end of the support frame 12 is connected to the containment frame 11, and the upper end of the support frame 12 is flush with the upper end of the containment frame 11. The cover assembly 2 includes a first cover 21, a second cover 22 and a third cover 23. The first cover plate 21, the second cover plate 22 and the third cover plate 23 are movably arranged on the enclosure assembly 1 along the length direction of the hull, and are overlapped and sleeved in sequence end to end. The height of the first cover plate 21, the height of the second cover plate 22 and the height of the third cover plate 23 increase in sequence along the length direction of the hull.

[0047] It can be seen that the first cover plate 21 can be moved to the bottom of the second cover plate 22 along the length direction of the hull, and the second cover plate 22 can be moved to the bottom of the third cover plate 23 along the length direction of the hull, so that the first cover plate 21, the second cover plate 22 and the third cover plate 23 are in a stacked state. Similarly, the first cover plate 21, the second cover plate 22 and the third cover plate 23 can also be moved in the opposite direction along the length direction of the hull, so that the first cover plate 21, the second cover plate 22 and the third cover plate 23 are overlapped end to end in sequence, and the first cover plate 21, the second cover plate 22 and the third cover plate 23 are in an unfolded state. When it is necessary to open the hatch, move the first cover plate 21, the second cover plate 22 and the third cover plate 23 to a stacked state, and the first cover plate 21, the second cover plate 22 and the third cover plate 23 can be selectively located on the enclosure frame 11 or the two support frames 12. If it is located on the enclosure frame 11, the hatch is partially covered. If it is located on the two support frames 12, the cover assembly 2 is fully opened and the hatch is completely unobstructed. The state of the cover assembly 2 can be flexibly selected according to actual needs, which has strong applicability. When the hatch needs to be closed, the first cover 21, the second cover 22 and the third cover 23 are moved to the unfolded state, and the first cover 21, the second cover 22 and the third cover 23 are moved to the enclosure frame 11 to cover the hatch.

[0048] When the cover assembly 2 is fully opened, the cover assembly 2 does not block the hatch, which can prevent the cover assembly 2 from hindering the workers from loading and unloading goods, ensuring work efficiency, and the workers in the cargo hold have an unobstructed view, and can clearly observe the position of the goods outside the cargo hold, avoiding the phenomenon of workers being injured by goods due to blocked vision, ensuring the safety of the workers. In addition, when the hatch assembly is fully opened, it can also ensure that large-sized goods can enter the hatch of the cargo hold smoothly, avoiding bumps and damages caused by the hatch being blocked.

[0049] In this embodiment, one second cover plate 22 is provided. In other embodiments, two or more second cover plates 22 may be provided according to actual needs, and any two adjacent second cover plates 22 are overlapped and sleeved end to end, and the number of the second cover plates 22 is not limited here.

[0050] Alternatively, if Figures 2 to 4 As shown, the hatch cover device also includes a guide rail assembly 3 and a driving mechanism 4. The guide rail assembly 3 includes a first guide rail 31, a second guide rail 32 and a third guide rail 33. The first guide rail 31, the second guide rail 32 and the third guide rail 33 are all arranged on the enclosure assembly 1 and extend along the length direction of the hull. The first cover plate 21 is slidably matched with the first guide rail 31, the second cover plate 22 is slidably matched with the second guide rail 32, and the third cover plate 23 is slidably matched with the third guide rail 33. The driving mechanism 4 is arranged on the third cover plate 23, and is used to drive the first cover plate 21 to move along the first guide rail 31. The first cover plate 21 is provided with a first limit member 211 (see Figure 5 The first stopper 211 can abut against the second cover plate 22. The second cover plate 22 is provided with a second stopper 221 at one end away from the third cover plate 23 (see Figure 6 As shown in FIG. 2 , the second limiting member 221 can abut against the third cover plate 23 .

[0051] When the hatch needs to be opened, the driving assembly is started, and the driving assembly drives the first cover plate 21 to move along the first guide rail 31 until the first limiter 211 abuts against the second cover plate 22. At this time, the first cover plate 21 is located below the second cover plate 22, that is, the first cover plate 21 and the second cover plate 22 are stacked. After that, the first cover plate 21 continues to move along the first guide rail 31, which will drive the second cover plate 22 to move along the second guide rail 32 until the second limiter 221 abuts against the third cover plate 23. At this time, the first cover plate 21 and the second cover plate 22 are both located below the third cover plate 23, that is, the first The cover plate 21, the second cover plate 22 and the third cover plate 23 are in a stacked state. At this time, the first cover plate 21, the second cover plate 22 and the third cover plate 23 are located on the enclosure frame 11, and the hatch is partially covered by the cover plate assembly 2. Then the first cover plate 21 continues to move along the first guide rail 31, which will drive the second cover plate 22 to continue to move along the second guide rail 32, and at the same time drive the third cover plate 23 to move along the third guide rail 33, until the first cover plate 21, the second cover plate 22 and the third cover plate 23 move to the support frame 12. At this time, the cover plate assembly 2 is fully opened and the hatch is completely unobstructed.

[0052] Alternatively, if Figures 2 to 4As shown, the hatch cover device further includes a first action wheel 212, a second action wheel 222 and a third action wheel 231. The driving mechanism 4 includes a rotating motor 41 and a driving wheel 42. The housing of the rotating motor 41 is disposed on the first cover 21, and the output end of the rotating motor 41 is drivingly connected to the driving wheel 42. The driving wheel 42 and the first action wheel 212 are disposed on the first cover 21 at intervals along the extension direction of the first cover 21, and both are rollingly matched with the first guide rail 31 (see Figure 4 , Figure 7 and Figure 8 The second action wheel 222 is disposed on the second cover plate 22 and is in rolling cooperation with the second guide rail 32 (see Figure 4 , Figure 7 and Figure 8 The third action wheel 231 is disposed on the third cover plate 23 and is in rolling cooperation with the third guide rail 33 (see Figure 4 ).

[0053] When the hatch is opened, the rotating motor 41 is started, and the rotating motor 41 drives the driving wheel 42 to rotate, and the driving wheel 42 and the first guide rail 31 are in rolling cooperation, so the driving wheel 42 will roll along the first guide rail 31, thereby driving the first cover plate 21 to move along the first guide rail 31, and at the same time, the first action wheel 212 rolls along the first guide rail 31, thereby driving the first cover plate 21 to move along the first guide rail 31, until the first limit piece 211 of the first cover plate 21 abuts against the second cover plate 22, the first cover plate 21 will drive the second cover plate 22 to move along the second guide rail 32, and at the same time, the second action wheel 222 rolls along the second guide rail 32 until the second limit piece 221 of the second cover plate 22 abuts against the third cover plate 23, and the first cover plate 21 will drive the second cover plate 22 to move along the second guide rail 32. 22 continues to move along the second guide rail 32, while driving the third cover plate 23 to move along the third guide rail 33, and at the same time the third action wheel 231 rolls along the third guide rail 33. The structure is simple and easy to operate. By setting the first action wheel 212, the second action wheel 222 and the third action wheel 231, the friction between the first cover plate 21 and the first guide rail 31, between the second cover plate 22 and the second guide rail 32, and between the third cover plate 23 and the third guide rail 33 can be reduced. In addition, through the rolling cooperation between the guide rail and the action wheel, a guiding effect can be provided for the first cover plate 21, the second cover plate 22 and the third cover plate 23, thereby improving their movement accuracy and preventing the first cover plate 21, the second cover plate 22 and the third cover plate 23 from tilting and shifting.

[0054] Alternatively, if Figures 2 to 4 As shown, the hatch cover device further includes a first clamping member 213 and a second clamping member 223. The first clamping member 213 is disposed on a side of the first cover 21 close to the second cover 22, and a first clamping groove (not shown in the figure) is provided on a side of the second cover 22 close to the first cover 21, and the first clamping member 213 can be clamped in the first clamping groove (see Figure 6 ). The second clamping member 223 is arranged on the side of the second cover plate 22 close to the third cover plate 23, and the side of the third cover plate 23 close to the second cover plate 22 is provided with a second clamping groove (not shown in the figure), and the second clamping member 223 can be clamped in the second clamping groove. When closing the hatch, the driving mechanism 4 drives the first cover plate 21 to move along the length direction of the hull, and gradually moves away from the second cover plate 22, until the first clamping member 213 is clamped with the first clamping groove, and then the first cover plate 21 continues to move, which will drive the second cover plate 22 to move, and make the second cover plate 22 gradually move away from the third cover plate 23, until the second clamping member 223 is clamped with the second clamping groove, at which time the first cover plate 21, the second cover plate 22 and the third cover plate 23 will be in the unfolded state, and then the first cover plate 21 continues to move until the first cover plate 21, the second cover plate 22 and the third cover plate 23 completely cover the hatch, with a simple structure and convenient operation. By arranging the first clamping member 213 to be engaged with the first clamping groove and the second clamping member 223 to be engaged with the second clamping groove, not only can the first cover plate 21 drive the second cover plate 22 and the third cover plate 23 to move, but also it can ensure that the first cover plate 21, the second cover plate 22 and the third cover plate 23 are always overlapped and sleeved with each other to prevent detachment, thereby ensuring the normal use of the hatch cover device.

[0055] Alternatively, if Figure 2 , Figure 3 and Figure 6As shown, the hatch cover device further includes a first guide assembly 5 and a second guide assembly 6. The first guide assembly 5 and the second guide assembly 6 each include a mounting seat 51 and a first roller 52, and the first roller 52 is rotatably disposed on the mounting seat 51. The mounting seat 51 of the first guide assembly 5 is disposed on the second cover plate 22, and the first roller 52 of the first guide assembly 5 is in rolling contact with the upper surface of the first cover plate 21. The mounting seat 51 of the second guide assembly 6 is disposed on the third cover plate 23, and the first roller 52 of the second guide assembly 6 is in rolling contact with the upper surface of the second cover plate 22. When the hatch is opened, the first cover plate 21, the second cover plate 22 and the third cover plate 23 all move along the length direction of the hull until the three are stacked. When the first cover plate 21 moves to below the second cover plate 22, the first roller 52 of the first guide assembly 5 will roll along the upper surface of the first cover plate 21, and when the second cover plate 22 moves to below the third cover plate 23, the first roller 52 of the second guide assembly 6 will roll along the upper surface of the second cover plate 22. By setting the mounting seat 51, a mounting base is provided for the first roller 52, and the first roller 52 of the first guide assembly 5 can reduce the friction between the upper surface of the first cover plate 21 and the second cover plate 22, avoid wear between the first cover plate 21 and the second cover plate 22, and ensure the normal use of the hatch cover device. Similarly, the first roller 52 of the second guide assembly 6 can reduce the friction between the upper surface of the second cover plate 22 and the third cover plate 23, and avoid wear between the second cover plate 22 and the third cover plate 23.

[0056] Alternatively, if Figures 1 to 3 As shown, the hatch cover device also includes a first stopper 7 and a second stopper 8. The first stopper 7 is arranged at one end of the enclosure frame 11 away from the support frame 12, and is used to stop the first cover plate 21 along the length direction of the hull. The second stopper 8 is arranged at one end of the support frame 12 away from the enclosure frame 11, and is used to stop the third cover plate 23 along the length direction of the hull. When opening the hatch, the first cover plate 21, the second cover plate 22 and the third cover plate 23 are moved along the length direction of the hull and switched to a stacked state, and then the first cover plate 21, the second cover plate 22 and the third cover plate 23 are continued to be moved until the second stopper 8 abuts against the third cover plate 23, at which time the first cover plate 21, the second cover plate 22 and the third cover plate 23 will be located on the support frame 12 in a stacked state, so that the hatch is fully opened. When closing the hatch, the first cover plate 21, the second cover plate 22 and the third cover plate 23 are moved along the length direction of the hull and switched to the unfolded state, and then the first cover plate 21, the second cover plate 22 and the third cover plate 23 are continued to be moved until the first cover plate 21 abuts against the second stopper 8. At this time, the first cover plate 21, the second cover plate 22 and the third cover plate 23 will be located on the enclosure frame 11 in the unfolded state, so that the hatch is completely covered.

[0057] In this embodiment, a buffer layer is provided on both the first stopper 7 and the second stopper 8. The buffer of the first stopper 7 is provided on the side of the first stopper 7 facing the first cover plate 21, and the buffer of the second stopper 8 is provided on the side of the second stopper 8 facing the third cover plate 23. When the first cover plate 21 is limited, the first stopper 7 will abut against the first cover plate 21 through the buffer, and when the third cover plate 23 is limited, the second stopper 8 will abut against the third cover plate 23 through the buffer. By providing the buffer, the impact force between the first cover plate 21 and the first stopper 7, and between the third cover plate 23 and the second stopper 8 can be reduced, thereby avoiding damage to the first cover plate 21 and the third cover plate 23.

[0058] Exemplarily, the buffer comprises rubber.
