A c-type liquid tank support structure and a ship

Abstract

The application provides a C-shaped liquid tank supporting structure and a ship. The C-shaped liquid tank supporting structure comprises first and second supports, first and second connecting structures. The first pad plate below the first support is fixedly connected with the first connecting structure to stably connect the C-shaped liquid tank with the ship deck and ensure stability. The second pad plate below the second support is slidably connected with the second connecting structure to leave a certain degree of freedom at one end of the C-shaped liquid tank, thereby relieving the influence of ship navigation shaking and thermal expansion and contraction deformation of the C-shaped liquid tank. The setting of the anti-floating glass steel, the anti-floating surrounding barrier and the anti-floating limiting block effectively prevents the C-shaped liquid tank from jumping in the height direction. The stainless steel sliding plate is arranged in the second lower surrounding barrier, the upper part of the second insulating glass steel is inserted into the second upper surrounding barrier, and the lower part of the second insulating glass steel is inserted into the second lower surrounding barrier and pressed on the stainless steel sliding plate. The stainless steel sliding plate reduces the sliding friction of the insulating glass steel. The insulating glass steel replaces the laminated wood, thereby reducing the cost.

Description

Technical Field

[0001] This application relates to the technical field of ship design and manufacturing, and more specifically, to a C-type liquid tank support structure and a ship. Background Technology

[0002] Type C tanks reach temperatures of -163°C when loaded with LNG and -50°C when loaded with LPG. The tank bodies are typically made of 9-nickel steel, 5-nickel steel, or cryogenic steel. To prevent the cryogenic temperature from being conducted to the ship's structure, causing a drop in the hull's temperature and damaging it, and to prevent the hull's temperature from being conducted to the tank, increasing the tank's temperature and causing rapid LNG evaporation, thus reducing the tank's pressure holding time, the tank structure cannot be directly connected to the ship's hull. In existing technology, imported systems typically use laminated wood panels for insulation. However, laminated wood manufacturing is relatively complex, significantly impacting the manufacturing cost and timeline of Type C tanks. Furthermore, laminated wood panels are also relatively expensive.

[0003] In addition, ship navigation will produce floating swaying such as rolling and pitching, and the temperature change of the liquid tank itself will cause thermal expansion and contraction, which will have a significant impact on the C-type liquid tank. Summary of the Invention

[0004] The purpose of this application is to provide a C-type liquid tank support structure and a ship. The support structure allows the C-type liquid tank to be stably attached to the hull structure, while also having a certain degree of freedom to accommodate the deformation of the hull during navigation and the effects of its own thermal expansion and contraction. At the same time, fiberglass is used instead of laminated wood to reduce costs.

[0047] The lower surface of the first pad plate 21 is provided with a first upper enclosure 41 and the upper surface is provided with a first anti-buoyancy enclosure 43.

[0048] like Figure 6 and Figure 7 As shown, the second connecting structure 5 includes a second upper enclosure 51, a second lower enclosure 52, a second anti-float enclosure 53, a second anti-float fiberglass 54, a second insulating fiberglass 55, a second anti-float limiting block 56, and a stainless steel sliding plate 57; the second upper enclosure 51 and the second anti-float enclosure 53 are both groove structures with surrounding cover, and the second lower enclosure 52 is a groove structure with one pair of uncovered sides;

[0049] The lower surface of the second pad 31 is provided with a second upper enclosure 51, and the upper surface is provided with a second anti-buoyancy enclosure 53. The surface of the ship deck directly below the second pad 31 is provided with a second lower enclosure 52. The groove structure of the second lower enclosure 52 extends longitudinally. A stainless steel sliding plate 57 is provided in the second lower enclosure 52. The upper part of the second insulating fiberglass 55 is inserted into the second upper enclosure 51, and the lower part of the second insulating fiberglass 55 is inserted into the second lower enclosure 52 and pressed on the stainless steel sliding plate 57. A second anti-buoyancy fiberglass 54 is provided in the second anti-buoyancy enclosure 53. The first end of the second anti-buoyancy limiting block 56 is provided at a predetermined distance above the second anti-buoyancy fiberglass 54, and the second end is fixedly connected to the ship deck.

[0050] In this embodiment, the first pad 21 below the first support 2 forms a fixed connection with each component of the first connecting structure 4, which is used to form a stable connection between the C-type liquid tank 1 and the ship's deck 100, ensuring the stability of the C-type liquid tank 1 during navigation. Meanwhile, the second pad 31 below the second support 3 forms a sliding connection with the second connecting structure 5, allowing one end of the C-type liquid tank 1 to retain a certain degree of freedom, thus mitigating the impact of ship swaying on the C-type liquid tank 1. Furthermore, the C-type liquid tank 1 itself experiences significant longitudinal deformation stress due to thermal expansion and contraction; this stress can also be mitigated by the sliding connection between the second pad 31 and the second connecting structure 5, allowing for adaptive movement to alleviate the effects of thermal expansion and contraction.

[0051] In this embodiment, the installation of the first anti-buoyancy fiberglass 44, the first anti-buoyancy enclosure 43, and the first anti-buoyancy limiting block 46, as well as the installation of the second anti-buoyancy fiberglass 54, the second anti-buoyancy enclosure 53, and the second anti-buoyancy limiting block 56, effectively prevents the C-type liquid tank 1 from jumping in the height direction.

[0053] Furthermore, in this embodiment, using insulated fiberglass instead of laminated wood not only simplifies the manufacturing process but also solves the problems associated with laminated wood.

[0054] Furthermore, by using the first support 2, the second support 3, the first connecting structure 4, and the second connecting structure 5 of this embodiment, the C-type liquid tank support no longer needs to manufacture a saddle for water pressure testing and a saddle for transporting liquid tanks, which greatly shortens the manufacturing cycle, greatly reduces manufacturing time, and greatly saves material costs.

[0057] The epoxy resin layer is mainly used to fill gaps rather than for making strong connections, which reduces the amount of epoxy resin used and also helps to reduce costs.

[0068] This embodiment also provides a ship, including the C-type liquid tank support structure in the aforementioned scheme, and also includes a C-type liquid tank 1, which is installed on a first support 2 and a second support 3.

[0069] This embodiment also provides a construction method for the aforementioned C-type liquid tank support structure, the steps of which include:

[0070] In the first step, before hoisting the C-type liquid tank 1, the first support 2 and the second support 3 are installed on the C-type liquid tank 1 respectively. The first support 2 is welded in the following order: first arc-shaped pad 22, first web plate 23, first rib plate 25, first arc-shaped arch plate 24, first pad plate 21, first anti-buoyancy barrier 43, and first upper barrier 41. The second support 3 is welded in the following order: second arc-shaped pad 32, second web plate 33, second rib plate 35, second arc-shaped arch plate 34, second pad plate 31, second anti-buoyancy barrier 53, and second upper barrier 51. Among them, the verticality of the web plate (first web plate 23 and second web plate 33) after welding and the flatness of the pad plate (first pad plate 21 and second pad plate 31) after welding meet the predetermined tolerance requirements, and the distance between the first support 2 and the second support 3 meets the predetermined tolerance requirements.

[0071] In the second step, the first lower retaining block 42 of the first support 2 is welded to the upper hull deck 100 to form a four-sided groove for installing the first insulating fiberglass 45. The second lower retaining block 52 of the second support 3 is welded to the upper hull deck 100 to form a groove with openings on both sides for installing the second insulating fiberglass 55. A stainless steel sliding plate 57 is installed at the bottom of the groove of the second lower retaining block 52 and welded to the surface of the hull deck 100. The second insulating fiberglass 55 is laterally held in place by the two lateral ends of the second lower retaining block 52, but can move freely longitudinally due to displacement or thermal expansion and contraction. The longitudinal spacing, lateral spacing, and flatness of the structures of the first lower retaining block 42 and the second lower retaining block 52 meet the predetermined tolerance requirements.

[0072] The third step is to fill the first lower enclosure 42 with an epoxy resin layer, place the first insulating fiberglass 45 in the first lower enclosure 42, and fill the gap formed between the first insulating fiberglass 45 and the first lower enclosure 42 with the epoxy resin layer. Then, install the first insulating fiberglass 45 on the stainless steel sliding plate 57 of the second lower enclosure 52, ensuring that the installation meets the predetermined tolerance requirements.

[0073] The fourth step is to hoist the C-type liquid tank 1 once, so that the first lower enclosure 42 on the underside of the first pad 21 of the first support 2 is placed on the first insulating fiberglass 45, and the second lower enclosure 52 on the underside of the second pad 31 of the second support 3 is placed on the second insulating fiberglass 55, thus completing the alignment.

[0074] The fifth step involves the secondary hoisting of the C-type liquid tank 1. The C-type liquid tank 1 is slowly hoisted to approximately 500mm directly above the first insulating fiberglass 45 and the second insulating fiberglass 55. An epoxy resin layer is applied inside the first lower enclosure 42 and the second lower enclosure 52, and an approximately 20mm thick epoxy resin layer is applied to the upper surfaces of the first insulating fiberglass 45 and the second insulating fiberglass 55. Then, the first lower enclosure 42 on the underside of the first pad 21 of the first support 2 is lowered onto the first insulating fiberglass 45, and the second lower enclosure 52 on the underside of the second pad 31 of the second support 3 is lowered onto the second insulating fiberglass 55, completing the secondary alignment and installation.

[0075] The sixth step is to fill the first anti-buoyancy enclosure 43 and the second anti-buoyancy enclosure 53 with epoxy resin adhesive layer, and then install the first anti-buoyancy fiberglass 44 into the first anti-buoyancy enclosure 43 and the second anti-buoyancy fiberglass 54 into the second anti-buoyancy enclosure 53.

[0076] Step 7: Weld one end of the first anti-buoyancy limiting block 46 to the hull deck 100, and position the other end of the first anti-buoyancy limiting block 46 at a predetermined distance above the first anti-buoyancy fiberglass 44, preferably at a distance of about 5mm. Weld one end of the second anti-buoyancy limiting block 56 to the hull deck 100, and position the other end of the second anti-buoyancy limiting block 56 at a predetermined distance above the second anti-buoyancy fiberglass 54, preferably at a distance of about 5mm, to limit the floating that may occur when the C-type liquid tank is submerged by seawater.

[0077] Step 8: After the epoxy resin layer has solidified, the installation of the C-type liquid tank support structure is complete.

[0078] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
