Technical Field

[0001] This utility model relates to the field of ship hatch cover technology, and specifically discloses a detachable ship hatch cover. Background Technology

[0002] Ships are a general term for all kinds of vessels. A ship is a means of transportation that can navigate or anchor in waterways for transport or operations. Depending on the specific requirements of its use, a ship has different technical specifications, equipment, and structural forms. A ship is a man-made means of transportation that primarily operates in geographical waters. Furthermore, civilian ships are generally called boats, military ships are called warships, and small boats are called dinghies or rafts; collectively, they are called ships or dinghies. Hatch covers are an important component of a ship; they are the closing devices for deck openings, serving to seal hatches, protect cargo, and partially support the platform.

[0003] Most existing ship hatch covers are integral structures, which are very inconvenient to maintain and replace. Large hoisting equipment is required to lift the entire hatch cover, which not only consumes a lot of manpower, material resources and time, but also makes the operation difficult in the confined space of the ship. Therefore, a detachable ship hatch cover is needed to solve this problem. Utility Model Content

[0004] This utility model proposes a detachable ship hatch cover. By designing the hatch cover body as multiple detachable splicing blocks, maintenance and replacement can be performed by simply disassembling the corresponding splicing blocks, eliminating the need to hoist the entire hatch cover body. This saves manpower, resources, and time, and reduces operational difficulty.

[0005] This utility model is implemented as follows: a detachable ship hatch cover includes a hatch cover body, which is composed of an outer rectangular frame and an inner detachable splicing component.

[0006] The splicing assembly includes multiple splicing blocks disposed within the frame. The multiple splicing blocks are detachably connected by a connecting component, and the multiple splicing blocks together cover the internal area of ​​the frame. A sealing gasket is provided on the side of each splicing block and the contact surface with the adjacent splicing block or the frame.

[0007] The connecting assembly includes a second connector disposed at the side wall connection between two adjacent splicing blocks; both ends of the second connector are detachably connected to the two adjacent splicing blocks by fixing bolts.

[0008] The connecting assembly also includes a third connector disposed on the upper surface at the corner intersection of every four adjacent splicing blocks. The outer wall of the third connector is detachably connected to a corresponding splicing block below it by four fixing bolts.

[0009] As a preferred embodiment of the detachable ship hatch cover of this utility model, the outer walls of multiple splicing blocks near the frame are all fixedly connected with first connecting members, and the multiple first connecting members are detachably connected to the frame by fixing bolts.

[0010] As a preferred embodiment of the detachable ship hatch cover of this utility model, two positioning posts are fixedly connected to one side wall of the splicing block, and two positioning holes are opened on the other side wall of the splicing block. One of the positioning posts on the splicing block is adapted to the positioning hole on the adjacent splicing block and inserted therein for positioning between adjacent splicing blocks.

[0011] As a preferred embodiment of the detachable ship hatch cover of this utility model, the rear end face of the splicing block is provided with reinforcing ribs.

[0012] As a preferred embodiment of the detachable ship hatch cover of this utility model, both the splicing block and the frame are made of high-strength steel.

[0013] The beneficial effects of this utility model are:

[0014] 1. The two adjacent splicing blocks are fixed by the second connector, and then the upper surface of the corner intersection of the four adjacent splicing blocks is fixed by the fixing bolts through the third connector. This process is repeated until the installation of the entire hatch cover body is completed. By designing the hatch cover body as multiple detachable splicing blocks, only the corresponding splicing blocks need to be removed during maintenance and replacement. There is no need to lift the entire hatch cover body, which saves manpower, material resources and time and reduces the difficulty of operation.

[0015] 2. The positioning pins and positioning holes are used to position the splicing blocks during installation, thereby improving the accuracy and efficiency of the installation. Attached Figure Description

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0023] Please see Figure 1-4 A detachable ship hatch cover includes a hatch cover body, which is composed of an outer rectangular frame 1 and an inner detachable splicing component.

[0024] The splicing assembly includes multiple splicing blocks 2 disposed within the frame 1. The multiple splicing blocks 2 are detachably connected to each other via a connecting component, and the multiple splicing blocks 2 together cover the internal area of ​​the frame 1. A sealing gasket 201 is provided on the side of each splicing block 2 and the contact surface with the adjacent splicing block 2 or the frame 1.

[0025] The connecting component includes a second connector 3 disposed at the side wall connection between two adjacent splicing blocks 2; both ends of the second connector 3 are detachably connected to the two adjacent splicing blocks 2 by fixing bolts.

[0026] The connecting assembly also includes a third connector 4 disposed on the upper surface at the corner intersection of every four adjacent splicing blocks 2. The outer wall of the third connector 4 is detachably connected to a corresponding splicing block 2 below it by four fixing bolts.

[0027] In this embodiment: During installation, one splicing block 2 is first placed in the corresponding position inside the frame 1, and then another splicing block 2 is spliced ​​with the previous splicing block 2. Then, the two adjacent splicing blocks 2 are fixed by fixing bolts through the second connector 3, and so on. Then, the upper surface of the corner intersection of the four adjacent splicing blocks 2 is fixed by fixing bolts through the third connector 4 until the installation of the entire hatch cover body is completed. During disassembly, simply loosen the fixing bolts to remove the corresponding splicing block 2. Thus, by designing the hatch cover body as multiple detachable splicing blocks 2, during maintenance and replacement, only the corresponding splicing block 2 needs to be removed, without the need to hoist the entire hatch cover body, saving manpower, material resources and time, and reducing the difficulty of operation.

[0028] The sealing gasket 201 ensures the airtightness of the hatch cover body, preventing seawater from entering the cabin.

[0029] As a technical optimization of this utility model, a first connector 202 is fixedly connected to the outer wall of a plurality of splicing blocks 2 near the frame 1, and the plurality of first connectors 202 are detachably connected to the frame 1 by fixing bolts.

[0030] In this embodiment: the splicing block 2 near the frame 1 is fixed to the frame 1 by the fixing bolt through the first connector 202, thereby fixing the frame 1 to the splicing block 2 located at the edge.

[0031] As a technical optimization of this utility model, two positioning posts 5 are fixedly connected to one side wall of the splicing block 2, and two positioning holes 501 are opened on the other side wall of the splicing block 2. One of the positioning posts 5 on the splicing block 2 is adapted to the positioning hole 501 on the adjacent splicing block 2 and inserted therein for positioning between the adjacent splicing blocks 2.

[0032] In this embodiment, the positioning post 5 and the positioning hole 501 are used to position the splicing block 2 during installation, thereby improving the accuracy and efficiency of the installation.

[0033] As a technical optimization of this utility model, the rear end face of the splicing block 2 is provided with reinforcing ribs.

[0034] In this embodiment, reinforcing ribs are used to improve the rigidity and strength of the splicing block 2 and prevent deformation.

[0035] As a technical optimization of this utility model, both the splicing block 2 and the frame 1 are made of high-strength steel.

[0036] In this embodiment: high-strength steel has extremely high yield strength and tensile strength, effectively supporting the weight of cargo and equipment as well as environmental loads such as waves, wind and snow on the deck, preventing the splicing block 2 from undergoing plastic deformation or breakage under heavy pressure.

[0037] The working principle and usage process of this utility model are as follows: During installation, first place one splicing block 2 in the corresponding position inside the frame 1, and fix the splicing block 2 near the frame 1 to the frame 1 with fixing bolts through the first connector 202. Then, splice another splicing block 2 with the previous splicing block 2, and then fix the spliced ​​adjacent splicing blocks 2 with fixing bolts through the second connector 3. In this way, fix the upper surface of the corner intersection of the four adjacent splicing blocks 2 with fixing bolts through the third connector 4 until the installation of the entire hatch cover body is completed. During disassembly, simply loosen the fixing bolts to remove the corresponding splicing block 2. By designing the hatch cover body as multiple detachable splicing blocks 2, during maintenance and replacement, only the corresponding splicing block 2 needs to be removed, without the need to hoist the entire hatch cover body, saving manpower, material resources and time, and reducing the difficulty of operation.
