In actual installation, according to the size and application requirements of the ship body 1, a plurality of openings can be formed in the top of the ship body 1, and correspondingly, a cabin cover 6 and a cabin frame 7 which are matched with each other are arranged at each opening. In the solution shown in fig. 1, the top of one ship hull 1 is exemplarily shown to be provided with three openings, and it can be understood that the sizes of the openings may be uniform or non-uniform according to the requirement.

By adopting the design, when water splashes to the hatch cover 6, part of water is blocked by the boss part 71 and the groove part 61 which are in plug fit, the residual water is prevented from entering the inside of the ship body by the sealing ring 8 in the groove part 61, and compared with a structure which is only provided with the sealing ring, the sealing effect of the sealing structure design of the ship body is better.

Of course, a plurality of boss portions and groove portions which are inserted and matched with each other may be arranged between the cabin frame 7 and the cabin cover 6 along the circumferential direction to form a multi-layer barrier, so as to further improve the sealing performance between the cabin cover 6 and the cabin frame 7, and achieve a better sealing effect.

In addition, the hatch cover 6 can be made of aluminum alloy, is firmer, more stable and less prone to deformation compared with a plastic material, and can prevent the reduction of the sealing effect caused by the deformation of the hatch cover 6; the hull 1 may be made of aluminum alloy or carbon fiber, which greatly reduces the weight of the hatch cover 6 and the hull 1 while ensuring the strength thereof.

In a specific embodiment, the boss portion 71 is disposed on the cabin frame 7, and the groove portion 61 is disposed on the cabin cover 6, so that after the cabin cover 6 is closed, the boss portion 71 is inserted into the groove portion 61, and an opening of the groove portion 61 faces the cabin frame 7, as shown in fig. 8, when water splashes, water blocked by the groove portion 61 and the boss portion 71 can flow down along the current, and cannot enter the inside of the groove portion 61, thereby avoiding water from accumulating inside the groove portion 61 and affecting the sealing ring 8 disposed in the groove portion 61.

Of course, in actual installation, the groove portion 61 may be disposed on the cabin frame 7, and the boss portion 71 may be disposed on the cabin cover 6, which may be determined according to processing requirements and actual application requirements.

In the specific arrangement, the frame body of the tank frame 7 is bent upward from the inner peripheral wall thereof to form the boss portion 71, and the frame body and the hull 1 may be fixedly connected by a fastening member or may be connected by welding or the like.

Wherein, the height of boss portion 71 is 2 ~ 4 times of the thickness of the frame body of cabin frame 7 to the splash that splashes when effectively separating the navigation, of course, in practical application, the height of boss portion 71 can set up as required, and the groove depth phase-match of concave part 61 sets up.

In this embodiment, after the tank frame 7 is fixed to the hull 1, a sealing layer is further provided therebetween.

The sealing layer has the function of ensuring the sealing between the cabin frame 7 and the ship body 1 and preventing water from entering the inside of the ship body 1 from the cabin frame 7.

With the arrangement, when the hatch 6 is covered and opened, the boss part 71 can be normally inserted into the groove part 61, and the blockage caused by the interference of the boss part and the groove part due to machining errors and the like is avoided.

In practice, the hatch 6 provided with the groove portion 61 and the hatch frame 7 provided with the boss portion 71 are both integrally formed structures to ensure the strength of the hatch 6 and hatch frame 7 structures and to reduce the connecting portions to further ensure the sealing property.

As shown in fig. 8, the seal ring 8 is specifically provided on the groove bottom wall of the groove portion 61, and the boss portion 71 is inserted into the groove portion 61 and pressed against the seal ring 8 in a state where the hatch 7 closes the opening.

This design allows the seal ring 8 to be tightly fitted to the groove bottom walls of the boss portion 71 and the groove portion 81, thereby achieving a better sealing effect.

In the illustrated embodiment, the cross section of the sealing ring 8 is substantially rectangular, and when the hatch 6 is closed, the sealing ring 8 is located between the top wall of the boss portion 71 and the bottom wall of the groove portion 61; in actual installation, the cross section of the sealing ring 8 may be similar to a U shape, so that when the boss portion 71 is inserted into the groove portion 61, the boss portion 71 is also inserted into the U-shaped groove of the sealing ring 8 and is pressed against the bottom wall of the groove portion 61, and thus, not only is a seal formed between the top wall of the boss portion 71 and the bottom wall of the groove portion 61, but also a seal is formed between the two side walls at the top of the boss portion 71 and the groove side walls corresponding to the groove portion 61, and the sealing effect is better.

Of course, the arrangement of the sealing ring 8 is not limited to the above-described arrangement, and other arrangements are possible, for example: two sealing rings may be provided, which are respectively provided on two opposite sidewalls of the boss portion 71 or two opposite groove walls of the groove 61, specifically, an annular mounting groove for accommodating the sealing rings may be opened on the corresponding wall surface, and in a state where the hatch 6 closes the opening, the sidewall of the boss portion 71 and the groove wall of the groove portion 61 on the corresponding side press the sealing rings therebetween, so as to realize sealing between the hatch 6 and the hatch frame 7, and ensure a sealing effect of the hull 1; for another example: it is also possible to provide only one sealing ring 8, and the sealing ring 8 can be sleeved on the boss portion 71, and the sealing ring 8 is squeezed between the boss portion 71 and the second boss 612 in the closed state of the hatch 6, so that the sealing function can be achieved, and the structure is simpler compared with the above manner.

In addition to the above-mentioned solution, the bulkhead 62 is further provided on the hatch 6 along the circumferential direction, the bulkhead 62 includes the extending plate portion 621 extending outward from the connection portion between the sealing structure and the hatch 6, and the flap portion 622 bent from the outer periphery of the extending plate portion 621 toward the hatch frame 7, and in the embodiment shown in the drawing, the groove portion 61 is formed on the hatch 6, that is, the bulkhead 62 includes the extending plate portion 621 extending outward from the connection portion between the second protruding portion 612 and the hatch 6, and the flap portion 622 bent from the extending plate portion 621 toward the hatch frame 7, and when the hatch 6 closes the opening, a gap exists between the flap portion 622 and the hatch frame 7 so as not to affect the fit between the groove portion 61 and the flap portion 71.

The arrangement of the partition plate 62 can further improve the waterproof function, and water splashed on the ship body 1 is partially blocked by the partition plate 62, and then further waterproof is realized through the sealing structure.
