Abstract
Description
Technical Field
[0001] This utility model relates to the field of marine engineering technology, specifically to an installation structure for an LNG fuel tank of an ultra-large container ship. Background Technology
[0002] As a clean and efficient marine fuel, liquefied natural gas (LNG) is increasingly used on various types of ships, including container ships and bulk carriers, especially on container ships. LNG fuel tanks are assembled using installation structures, which are currently fixed mainly by welding. However, these existing installation structures generally lack effective protection for critical parts of the LNG fuel tank, especially its ends. This lack of protection makes the tank's vulnerable end caps susceptible to physical damage during ship construction, commissioning, operation, maintenance, and even accidental collisions or vibrations, potentially leading to serious safety hazards such as fuel leaks and structural failures. Utility Model Content
[0003] The purpose of this utility model is to provide an installation structure for an ultra-large container ship LNG fuel tank to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: an installation structure for an ultra-large container ship LNG fuel tank, including an installation base, a fuel tank body fixedly connected to the top of the installation base, an installation top plate overlapping the top of the installation base, a support plate on one side of the installation base, a welding block connected to the outside of the support plate, a cross groove I inside the installation top plate, a cross groove II inside the installation base, a protective structure on one side of the support plate, the protective structure being slidably connected within the cross groove I and the cross groove II, a sliding groove above the installation top plate, a limiting structure slidably connected within the sliding groove, the limiting structure being connected to the installation base, the protective structure including a limiting plate, an installation plate, and a handle, and a bolt inside the installation plate.
[0005] As a further preferred embodiment of this technical solution, one side of the welding block overlaps with the mounting top plate, the other side of the welding block overlaps with the mounting base, and the support plate overlaps with one end of the fuel tank body.
[0006] As a further preferred embodiment of this technical solution, the mounting plate is slidably connected in the first cross groove, the mounting plate is slidably connected in the second cross groove, and the limiting plate is fixedly connected to one side of the support plate.
[0007] As a further preferred embodiment of this technical solution, the handle is fixedly connected to one side of the limiting plate, the limiting plate is snapped into the mounting top plate, and the limiting plate is snapped into the mounting base.
[0008] As a further preferred embodiment of this technical solution, the mounting plate overlaps with the limiting plate, the mounting plate is connected to the support plate by a bolt, and a groove is provided in the mounting top plate.
[0009] As a further preferred embodiment of this technical solution, the limiting structure includes a sleeve plate, a locking plate, and a column. The sleeve plate is fixedly connected to one side of the mounting base, the locking plate is slidably connected in the sliding groove, and the column is fixedly connected to the outside of the mounting top plate and is locked in the sleeve plate.
[0010] As a further preferred embodiment of this technical solution, the card plate is snapped into the column, and the card plate is provided with bolt two, and the card plate is connected to the sliding groove through bolt two.
[0011] This utility model provides an installation structure for an ultra-large container ship's LNG fuel tank, which has the following advantages: (1) This utility model sets up an installation base, an installation top plate, a support plate and a protective structure. The support plate is snapped onto both sides of the installation base by the handle, and the support plate will overlap with the groove through the limiting plate. Then the installation plate is slid in the cross groove one and cross groove two. When the installation plate one moves to the appropriate position, it will contact the limiting plate. The installation plate is then threaded to the support plate by bolt one. Then the welding block is welded to the connection between the installation base and the installation top plate. This installation structure can protect both ends of the fuel tank body through the cooperation between the limiting plate, the installation plate and the bolt one, and can increase the stability after the installation base and the installation top plate are fixed, avoid the phenomenon of physical damage to the fragile end cap, and thus reduce the problem of serious safety hazards.
[0012] (2) By setting a limiting structure, the mounting top plate is overlapped above the mounting base. The mounting top plate will be inserted through the column and the sleeve plate. When the mounting top plate and the mounting base are completely in contact, the clamping plate will slide in the groove. When the clamping plate slides, it will be inserted through the sleeve plate and the column. The clamping plate is then connected to the mounting top plate through bolt 2. This can play a certain limiting role in fixing the mounting base and the mounting top plate, and avoid the phenomenon of the mounting base and the mounting top plate shifting during assembly.

[0014] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0015] This utility model provides a technical solution: such as Figure 1 and Figure 4 As shown in this embodiment, an installation structure for an ultra-large container ship LNG fuel tank includes an installation base 1, a fuel tank body 2 fixedly connected to the top of the installation base 1, an installation top plate 3 overlapping the top of the installation base 1, a support plate 4 on one side of the installation base 1, a welding block 5 connected to the outside of the support plate 4, a cross groove 8 in the installation top plate 3, a cross groove 9 in the installation base 1, a protective structure 6 on one side of the support plate 4, the protective structure 6 being slidably connected in the cross groove 8, the protective structure 6 being slidably connected in the cross groove 9, a sliding groove 11 on the top of the installation top plate 3, a limiting structure 7 being slidably connected in the sliding groove 11, the limiting structure 7 being connected to the installation base 1, and the protective structure 6 including a limiting plate 601, an installation plate 602 and a handle 604, and a bolt 603 in the installation plate 602.
[0016] like Figure 1 and Figure 3 As shown, one side of the welding block 5 overlaps with the mounting top plate 3, and the other side of the welding block 5 overlaps with the mounting base 1. The support plate 4 overlaps with one end of the fuel tank body 2. The mounting plate 602 is slidably connected in the cross groove 8 and the mounting plate 602 is slidably connected in the cross groove 9. The limiting plate 601 is fixedly connected to one side of the support plate 4. The handle 604 is fixedly connected to one side of the limiting plate 601. The limiting plate 601 is snapped into the mounting top plate 3 and the limiting plate 601. The mounting plate 602 overlaps with the limiting plate 601. The mounting plate 602 is connected to the support plate 4 by bolt 603. The mounting top plate 3 has a groove 10. By setting cross groove 8 and cross groove 9, when the support plate 4 overlaps with the groove 10 through the limiting plate 601, the mounting plate 602 is subsequently slid in the cross groove 8 and cross groove 9. This allows the cross groove 8 and cross groove 9 to guide the movement of the mounting plate 602, preventing the mounting plate 602 from getting stuck during movement, and also reinforcing the mounting base 1 and the mounting top plate 3.
[0017] like Figure 2 and Figure 4 As shown, the limiting structure 7 includes a sleeve plate 701, a clamping plate 702, and a column 703. The sleeve plate 701 is fixedly connected to one side of the mounting base 1. The clamping plate 702 is slidably connected in the slide groove 11. The column 703 is fixedly connected to the outside of the mounting top plate 3. The column 703 is clamped in the sleeve plate 701, and the clamping plate 702 is clamped in the column 703. The clamping plate 702 is provided with a bolt 704. The clamping plate 702 is connected to the slide groove 11 through the bolt 704. By setting the clamping plate 702 and the column 703, the mounting top plate 3 is overlapped above the mounting base 1. When the mounting top plate 3 is fully attached to the mounting base 1, the clamping plate 702 is driven to slide in the slide groove 11. When the clamping plate 702 slides, it will interlock with the sleeve plate 701 and the column 703, thereby locking the position of the mounting top plate 3 and preventing the mounting top plate 3 from becoming loose during welding.
[0018] This utility model provides an installation structure for an ultra-large container ship's LNG fuel tank, and its specific working principle is as follows: When the mounting structure is used to assemble the fuel tank body 2, the mounting top plate 3 can be overlapped on the mounting base 1. The mounting top plate 3 will be inserted into the sleeve plate 701 through the column 703. When the mounting top plate 3 and the mounting base 1 are fully attached, the clamping plate 702 will slide in the sliding groove 11. When the clamping plate 702 slides, it will be inserted into the sleeve plate 701 and the column 703. The clamping plate 702 is then connected to the mounting top plate 3 through bolt 2 704. Subsequently, the support plate 4 is snapped onto both sides of the mounting base 1 using the handle 604. The support plate 4 will overlap with the groove 10 through the limiting plate 601. Then, the mounting plate 602 is slid into the cross groove 8 and the cross groove 9. When the mounting plate 602 moves to the appropriate position, it will contact the limiting plate 601. The mounting plate 602 is then threadedly connected to the support plate 4 through the bolt 603. Finally, the welding block 5 is welded to the connection between the mounting base 1 and the mounting top plate 3.
[0019] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
