Description

Technical Field

[0001] The present invention relates to the technical field of ships, and more specifically to an anti-rotation integrated independent storage tank saddle and an anti-floating device. Background Art

[0002] With the increasingly stringent control of carbon emissions, LOC2 (liquid carbon dioxide) transport ships have emerged and gradually become a hot topic. LCO2 transport ships using C-type independent tanks are usually limited in diameter due to the high density and pressure of LCO2; at the same time, in order to ensure the ship's load capacity and overall performance, the main structural dimensions are usually large, leaving a large gap between the independent tank and the hull structure. If the saddle and anti-floating device design method commonly used in engineering is adopted, not only will the structure be poorly stressed, but it will also lead to excessive structural weight.

[0003] In addition, independent tanks, whether they are cargo tanks arranged inside the ship's cabin or fuel tanks arranged on the deck, will produce a rotational motion or tendency around their own axis during navigation at sea due to the influence of the ship's movement. In order to ensure the safety of the tank and the ship's structure, it is necessary to design a structure that can limit its rotational motion. The commonly used method is to disconnect the insulating wooden block directly below the tank, set up a steel structure in the open space and connect it to the tank and the saddle below, so as to achieve the purpose of stopping rotation. This design method will produce a smaller construction space near the insulating wooden blocks in the discontinuous area, causing construction difficulties; in addition, the steel structure will destroy the integrity and airtightness of the insulation system in the heat transfer channel between the tank and the saddle, which is not conducive to structural safety. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an anti-rotation integrated independent storage tank saddle and an anti-floating device to solve the problems mentioned in the background technology.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] The invention comprises a ship-carrying saddle, a cabin-carrying saddle, an anti-floating device and connecting bolts.

[0007] The cabin saddle is installed together with the independent storage tank, including the cabin saddle belly plate, the first supporting bracket, the first connecting panel, the curved bottom plate, and the bottom plate coaming;

[0008] The belly plate of the cabin saddle is arranged in a vertical plane, and the first supporting bracket and the first connecting panel are perpendicular to the belly plate;

[0009] The arc bottom plate is in a circular shape, with the same center as the independent tank bulkhead; bottom plate coamings are welded on both sides of the arc bottom plate, and the bottom plate coamings are located in the vertical plane. The preferred height of the bottom plate coamings is 1 / 5 to 2 / 3 of the thickness of the insulating wood block;

[0010] Insulating wood blocks are arranged in the space formed by the curved bottom plate, the bottom plate coaming and the independent storage tank bulkhead, and the insulating wood blocks are bonded to the curved bottom plate, the bottom plate coaming and the independent storage tank bulkhead by glue;

[0011] The design of the cabin saddle must meet the wrap angle requirements of the independent storage tank for the saddle. The preferred angle α is 150-160°, so as to ensure the load transfer and structural safety between the independent storage tank and the saddle.

[0012] The ship saddle is welded to the hull structure, including the ship saddle web, the second supporting bracket, and the second connecting panel;

[0013] The web of the ship-borne saddle and the web of the cabin-borne saddle are arranged in the same vertical plane, the second supporting bracket and the second connecting panel are perpendicular to the web of the ship-borne saddle; the second supporting bracket and the web of the cabin-borne saddle are arranged in mutual alignment;

[0014] The second connecting panel accompanying the ship and the first connecting panel accompanying the cabin are arranged in vertical alignment and connected together by bolts;

[0015] During the ship transportation, the inertial load generated by the independent storage tank is transmitted to the ship saddle through the tank saddle, and then to the hull structure;

[0016] The anti-floating device is directly welded to the cabin saddle and the independent tank shell to transfer the buoyancy load, including the cabin end anti-floating structure, the reinforced end anti-floating structure, and the insulating wood block;

[0017] The tank end anti-floating structure and the reinforced end anti-floating structure are both steel plate frame welded structures, with insulating wood blocks arranged between the two;

[0018] The anti-floating structure at the end of the cabin is strengthened and horizontal panels are arranged at the upper and lower ends of the insulating wood blocks. Steel coamings are welded at the horizontal panels of the anti-floating structure at the end to limit the movement of the insulating wood blocks; the insulating wood blocks are used for temperature isolation;

[0019] Under flooding conditions, the buoyancy of the independent tank is transmitted through the tank end anti-floating structure via the insulating wooden blocks to the reinforced end anti-floating structure, and further transmitted to the cabin saddle, and finally transmitted to the hull structure by the ship saddle.

[0020] The design features of the ship-mounted saddle and cabin-mounted saddle fully consider the spatial layout characteristics of the LCO2 transport ship, greatly reduce the weight of the saddle structure, optimize the structural force, and thus simplify the structural reinforcement plan;

[0021] The design features of the anti-floating device eliminate the need for additional counter-strengthening structures on the deck. While meeting the requirements for independent tank anti-floating under flooding conditions, it also greatly reduces the structural weight and simplifies the hull structure and construction.

[0022] The ship-mounted saddle can be constructed as a conventional hull structure, and the cabin saddle and anti-floating device can be constructed as independent parts; the two can be constructed at the same time, which greatly shortens the construction period;

[0023] After the cabin saddle and anti-floating device are installed with the independent storage tank, they are hoisted and installed on the ship's saddle as a whole. The two are connected by bolts for easy installation. This avoids the process of applying glue and installing insulating wooden blocks on the hull saddle in conventional designs, shortening the construction period and construction difficulty.

[0024] The anti-rotation structure is as follows:

[0025] The second insulating wood block includes three sections of annular insulating wood blocks and two sections of straight-edge insulating wood blocks; each section of the straight-edge insulating wood block is sandwiched between the two sections of annular insulating wood blocks;

[0026] The inner side walls of the annular insulating wooden block and the straight-edge insulating wooden block are both annular surfaces that are parallel to and fixed to the outer side walls of the independent storage compartment; the outer side walls of the annular insulating wooden block are annular surfaces that are parallel to and fixed to the arc-shaped bottom plate; the outer side walls of the straight-edge insulating wooden block are planes that are parallel to and fixed to the arc-shaped bottom plate.

[0027] The inner side wall of the arc bottom plate and the outer side wall of the second insulating wooden block are bonded and fixed by glue; and the outer side wall of the arc bottom plate and the accompanying saddle are bonded and fixed by glue.

[0028] The bottom plate coaming is fixed to the outer side wall of the independent storage tank by glue.

[0029] The inner side wall of the second insulating wooden block is bonded and fixed to the outer side wall of the independent storage compartment by glue.

[0030] Each straight-edge insulating wood block is provided with fixed baffles embedded in the straight-edge insulating wood block at both ends of the independent storage tank in the circumferential direction, and the fixed baffles are fixed to the side walls of the independent storage tank.

[0031] The advantage of the present invention over the prior art is that the present invention makes full use of the spatial layout characteristics of the LCO2 transport ship, optimizes the structural stress through the integrated saddle and anti-floating device design, greatly reduces the structural weight of the saddle and anti-floating device, and greatly shortens the construction period and construction difficulty. In addition, due to the extremely heavy weight of the independent storage tank, the traditional technology uses relatively heavy and costly supports, but the present invention boldly uses a relatively thin arc bottom plate in combination with a web plate for support, and through experiments it is found that the strength is sufficient to support the independent storage tank, breaking the traditional prejudice that only thick plates can be used for support, reducing the cost and complexity of use.

[0032] The present invention also limits the rotational movement between the insulation layer and the tank bulkhead, and the rotational movement between the insulation layer and the ship saddle by setting two straight-edge insulation wood blocks and three annular insulation wood blocks, thereby limiting the rotational movement between the saddle and the tank. The present invention ensures the continuity of the insulation wood blocks along the tank bulkhead, is conducive to load transfer, has a simple structure, is easy to build and install, and improves engineering applicability.

[0038] The specific implementation of the present invention will be described below in conjunction with the accompanying drawings.

[0039] like Figures 1 to 3 As shown, the present invention is an anti-rotation integrated independent storage tank saddle and anti-floating device, comprising a cabin saddle 4 fixed to an independent storage tank 1 and a ship saddle 6 fixed to a hull platform;

[0040] The cabin saddle 4 includes an arc-shaped bottom plate 9 that is in contact with the outer side wall of the independent storage tank 1, and the arc-shaped bottom plate 9 is supported on the cabin saddle web 16; the cabin saddle web 16 is supported on the first connecting panel 13;

[0041] The ship saddle 6 comprises a vertical ship saddle web 15, on which a second connection panel 14 is arranged, and the first connection panel 13 and the second connection panel 14 are connected and fixed by connecting bolts 5 after being matched;

[0042] The cabin saddle 4 is also supported by a reinforced end anti-floating structure 8, and the side wall of the independent storage tank 1 is also fixed with a cabin end anti-floating structure 7, and the cabin end anti-floating structure 7 is limited to be located below the reinforced end anti-floating structure 8;

[0043] Bottom plate enclosures are welded on both sides of the arc bottom plate 9, and the bottom plate enclosures, the arc bottom plate 9 and the outer side wall of the independent storage tank 1 form an area, and a second insulating wood block 10 is arranged in the area;

[0044] The second insulating wood block 10 includes three sections of annular insulating wood blocks 91 and two sections of straight-edge insulating wood blocks 92; each section of the straight-edge insulating wood block 92 is sandwiched between two sections of annular insulating wood blocks 91;

[0045] The inner walls of the annular insulating wood block 91 and the straight-edge insulating wood block 92 are both annular surfaces that are parallel to and fixed to the outer wall of the independent storage compartment 1; the outer wall of the annular insulating wood block 91 is annular surfaces that are parallel to and fixed to the arc bottom plate 9; the outer wall of the straight-edge insulating wood block 92 is a plane that is parallel to and fixed to the arc bottom plate 9.

[0046] A first supporting bracket 11 is provided at the angle between the cabin saddle web 16 and the outer side wall of the independent storage tank 1 .

[0047] A second supporting bracket 12 is provided at the angle between the ship saddle web 15 and the hull platform.

[0048] A first insulating wooden block 17 is provided between the cabin end anti-floating structure 7 and the reinforced end anti-floating structure 8 .

[0049] The anti-floating device 3 composed of the tank end anti-floating structure 7 and the reinforced end anti-floating structure 8 is symmetrically arranged relative to the vertical plane passing through the central axis of the independent storage tank 1.

[0050] The opening angle formed by the two anti-floating devices 3 relative to the central axis of the independent storage tank 1 is 150° to 160°.

[0051] The inner side wall of the arc bottom plate 9 and the outer side wall of the second insulating wood block 10 are bonded and fixed by glue; the outer side wall of the arc bottom plate 9 and the ship saddle 6 are bonded and fixed by glue.

[0052] The bottom plate enclosure is fixed to the outer side wall of the independent storage tank 1 by glue.

[0053] The inner wall of the second insulating wooden block 10 is bonded and fixed to the outer wall of the independent storage compartment 1 by glue.

[0054] Each straight-edge insulating wood block 92 is provided with fixed baffles 93 embedded in the straight-edge insulating wood block 92 at both ends in the circumferential direction of the independent storage compartment 1 , and the fixed baffles 93 are fixed to the side walls of the independent storage compartment 1 .

[0055] Each straight-edge insulating wood block 92 is provided with fixed baffles 93 embedded in the straight-edge insulating wood block 92 at both ends in the circumferential direction of the independent storage compartment 1 , and the fixed baffles 93 are fixed to the side walls of the independent storage compartment 1 .

[0056] Among them, the first insulating wood block 17 and the second insulating wood block 10 can play a role in heat insulation. Through the design of the ship saddle 6 and the cabin saddle 4, the function of supporting the independent storage tank 1 can be achieved. Under the condition of water inflow, the buoyancy of the independent storage tank 1 is transmitted to the reinforcement end stop-floating structure 8 through the cabin end stop-floating structure 7 through the first insulating wood block 17, and further transmitted to the cabin saddle 4, and finally transmitted to the hull structure by the ship saddle 6, which plays a role in fixing the independent storage tank 1.

[0057] The design features of the shipboard saddle 6 and the cabin saddle 4 fully consider the spatial layout characteristics of the LCO2 transport ship, greatly reduce the weight of the saddle structure, optimize the structural force, and thus simplify the structural reinforcement plan.

[0058] The design feature of the anti-floating device 3 eliminates the original additional counter-position reinforcement structure on the deck, and while meeting the anti-floating requirements of the independent storage tank 1 under water-influent conditions, it greatly reduces the structural weight and simplifies the hull structure and construction;

[0059] The ship saddle 6 can be constructed as a conventional hull structure, and the cabin saddle 4 and the anti-floating device 3 can be constructed as independent parts; the two are constructed at the same time, which greatly shortens the construction period;

[0060] After the cabin saddle 4 and the anti-floating device 3 are installed with the independent storage tank 1, they are hoisted and installed on the ship saddle 6 as a whole. The two are connected by bolts, which is easy to install. It also avoids the process of applying glue and installing insulating wooden blocks 2 on the hull saddle in conventional designs, shortening the construction period and construction difficulty.

[0061] By arranging the straight-edged insulating wooden blocks 92 and the spacing between the outer straight portions and the ring-mounted portions of the annular insulating wooden blocks 91 that cooperate with each other, the rotational movement between the second insulating wooden block 10 and the arc-shaped bottom plate 9 can be limited, thereby ultimately achieving the purpose of stopping the rotation of the independent storage compartment 1.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
