Description

Technical Field

[0001] This utility model belongs to the field of shipbuilding technology, specifically relating to an inclined anti-buoyancy device for an independent liquid cargo tank. Background Technology

[0002] In the field of liquid cargo transportation and storage, the safety and stability of liquid cargo tanks are of paramount importance. Liquid cargo tanks, especially independent liquid cargo tanks, are frequently subjected to various external forces during transportation, such as the rolling of the ship and the impact of waves. These external forces may cause the liquid inside the tank to slosh, which in turn puts pressure on the tank walls and structure, and may even lead to safety accidents.

[0003] To reduce the impact of liquid sloshing on the structure of cargo tanks, the traditional approach is to install longitudinal and transverse support structures inside the tanks. However, these support structures often only provide support in limited directions, offering limited effectiveness in suppressing oblique sloshing. This is particularly true in the space between the tank roof ramp and the inner shell plate, where the unique structure makes traditional support methods difficult to implement effectively.

[0004] Furthermore, the support structure within the liquid cargo tank must also consider the ease of installation, adjustment, and disassembly. Traditional support structures are often complex, difficult to adjust, and may damage other components due to excessive rigidity during use, affecting the overall safety and service life of the liquid cargo tank.

[0005] Therefore, the market urgently needs an anti-buoyancy device that can be independently installed between the sloping roof plate and the inner shell plate of the liquid cargo tank to provide sloping support force, and is easy to install, adjust and disassemble.

[0006] Therefore, an inclined anti-buoyancy device for independent liquid cargo tanks is designed to address the impact of liquid sloshing on the structure of the liquid cargo tank. Summary of the Invention

[0007] The purpose of this invention is to provide an inclined anti-buoyancy device for an independent liquid cargo tank in existing devices, so as to solve the problems mentioned in the background art.

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an inclined anti-buoyancy device for an independent liquid cargo tank, comprising an anti-buoyancy assembly, wherein the anti-buoyancy assembly includes an elbow plate, a top plate, a wall plate, a flat steel bar, a baffle plate, a pressure-bearing wooden block, and a jack screw, wherein:

[0009] Several flat steel bars are fixed to the top and bottom of the wall panel;

[0010] An elbow plate is fixedly connected between the top and bottom flat steel bars;

[0011] The top plate is fixed above the flat steel at the top;

[0012] The baffle is fixed above the top plate, the pressure-bearing wood is located above the top plate, the four baffles form a rectangular enclosure, the pressure-bearing wood is located inside the rectangular enclosure, any one of the baffles is provided with a sliding groove, an adjusting bolt is provided in the sliding groove, the adjusting bolt slides in the sliding groove, and the adjusting bolt abuts against the outer wall of the pressure-bearing wood;

[0013] A sealing plate is slidably connected to the side of the baffle away from the pressure-bearing wood. The sealing plate covers the groove. A threaded hole is provided on the sealing plate. The sealing plate is threadedly connected to the adjusting bolt through the threaded hole. An adjusting plate is rotatably connected to the sealing plate. An adjusting hole is provided in the center of the adjusting plate. The adjusting hole communicates with the threaded hole. The adjusting plate is bolted to the adjusting bolt through the adjusting hole.

[0014] A fixing block is fixed on the pressure-bearing wood. The fixing block has a ring structure and an installation groove is opened inside the fixing block. A spring is fixed in the installation groove. A telescopic block is fixed to the end of the spring away from the pressure-bearing wood. One end of the telescopic block is in the installation groove and the other end abuts against the baffle.

[0015] The baffle is bolted to the outer wall of the pressure-bearing wood.

[0016] The pressure-bearing timber has a threaded hole, and the jack screw is threadedly connected to the pressure-bearing timber and located above the pressure-bearing timber.

[0017] Furthermore, in this invention, the anti-buoyancy assembly is installed between the roof sloping plate and the inner shell plate.

[0018] Furthermore, the material used for the top plate, the wall plate, and the flat steel is 20Ni.

[0019] Furthermore, in this invention, the anti-buoyancy component is fixed to the inclined plate on the top of the cabin.

[0020] Furthermore, in this invention, the top of the anti-buoyancy component is parallel to the bottom of the inner shell plate.

[0021] Furthermore, in this invention, the wall panel is arranged around the top panel.

[0022] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: This invention, through its designed anti-buoyancy components, particularly the combination of wall panels, flat steel, and elbow plates, significantly enhances the connection strength and stability of the overall structure. This design ensures that the anti-buoyancy device can effectively resist liquid sloshing in the cargo tank, providing reliable oblique support, thereby reducing the potential risks caused by liquid sloshing in the cargo tank.

[0023] The position of the pressure timber can be precisely adjusted laterally using adjusting bolts and a adjusting disc, while the use of jack screws allows for longitudinal height adjustment. This dual adjustment mechanism enables the anti-floating assembly to adapt to different installation environments and requirements, ensuring optimal anti-floating performance.

[0024] The contact surface between the load-bearing timber and the top plate is reinforced by injecting adhesives such as resin. The adhesive layer formed after the resin cures not only enhances the connection strength but also simplifies the installation process and improves the durability of the device. Furthermore, after adjustment and curing, the jack screws and adjusting bolts can be removed, preventing potential damage to the surrounding structure from these rigid components during long-term use and facilitating subsequent maintenance and inspection.

[0025] The compact and efficient design of the anti-buoyancy components makes full use of the space between the roof ramp and the inner shell plate, providing not only the necessary support but also optimizing the internal layout of the cargo tank without adding any extra space burden.

[0037] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0038] Please see Figure 1-9 The present invention provides a technical solution: an inclined anti-buoyancy device for an independent liquid cargo tank, including an anti-buoyancy component 1;

[0039] like Figure 1 As shown, in some embodiments, the anti-buoyancy assembly 1 is installed between the roof ramp 2 and the inner shell plate 3.

[0040] like Figure 2-9 As shown, in some embodiments, the anti-buoyancy assembly 1 includes an elbow plate 101, a top plate 102, a wall plate 103, a flat steel bar 104, a baffle 105, a pressure-bearing timber 106, and a jack screw 107, wherein:

[0041] The top and bottom of the wall panel 103 are each fixed with a number of flat steel bars 104;

[0042] like Figure 5 As shown, in some embodiments, an elbow plate 101 is fixedly connected between the top and bottom flat steel bars 104; the elbow plate 101 is used to strengthen the connection between the flat steel bars 104 and the wall panel 103.

[0043] like Figure 4 As shown, in some embodiments, the top plate 102 is fixed above the top flat steel 104, and the top flat steel 104 is used to support the top plate 102.

[0044] like Figure 6 and Figure 7As shown, in some embodiments, the baffle 105 is fixed above the top plate 102, the pressure-bearing timber 106 is located above the top plate 102, the four baffles 105 form a rectangular enclosure, the pressure-bearing timber 106 is located within the rectangular enclosure, any one of the baffles 105 is provided with a sliding groove 1051, an adjusting bolt 1052 is provided in the sliding groove 1051, the adjusting bolt 1052 slides in the sliding groove 1051, the adjusting bolt 1052 abuts against the outer wall of the pressure-bearing timber 106, the adjusting bolt 1052 is used to adjust the position of the pressure-bearing timber 106.

[0045] A sealing plate 1053 is slidably connected to the side of the baffle 105 away from the pressure-bearing wood 106. The sealing plate 1053 covers the slide groove 1051. The sealing plate 1053 has a threaded hole and is threadedly connected to the adjusting bolt 1052 through the threaded hole. An adjusting plate 1054 is rotatably connected to the sealing plate 1053. An adjusting hole is opened in the center of the adjusting plate 1054 and communicates with the threaded hole. The adjusting plate 1054 is bolted to the adjusting bolt 1052 through the adjusting hole.

[0046] A fixing block 108 is fixed on the pressure-bearing wood 106. The fixing block 108 has a ring structure and an installation groove is provided inside the fixing block 108. A spring 109 is fixed in the installation groove. A telescopic block 110 is fixed to one end of the spring 109 away from the pressure-bearing wood 106. One end of the telescopic block 110 is in the installation groove and the other end abuts against the baffle 105.

[0047] The baffle 105 is bolted to the outer wall of the pressure-bearing timber 106, providing stable support and positioning for the pressure-bearing timber 106.

[0048] like Figure 8 As shown, in some embodiments, the pressure-bearing wood 106 has a resin inlet hole that allows adhesives such as resin to be injected into the contact surface between the pressure-bearing wood 106 and the top plate 102.

[0049] After curing, the resin can form a strong adhesive layer, which significantly enhances the connection strength between the pressure-bearing wood 106 and the top plate 102.

[0050] The pressure-bearing timber 106 has a threaded hole, and the jack screw 107 is threadedly connected to the pressure-bearing timber 106 and is located above the pressure-bearing timber 106. The lifting and lowering of the pressure-bearing timber 106 is controlled by turning the jack screw 107.

[0051] It should be noted that the wall panel 103 is arranged around the top plate 102, and the material used for the top plate 102, the wall panel 103 and the flat steel 104 is 20Ni.

[0052] The anti-buoyancy component 1 is fixed to the roof ramp 2, and the top of the anti-buoyancy component 1 is parallel to the bottom of the inner shell plate 3. This design enables the anti-buoyancy component 1 to effectively provide oblique support between the roof ramp 2 and the inner shell plate 3, reducing the swaying of liquid and liquid cargo tanks.

[0053] Working principle: When it is necessary to adjust the height of the anti-buoyancy component 1 longitudinally, rotate the jack screw 107.

[0054] When the jack screw 107 is rotated, the bolt will cause the pressure-bearing wood 106 to move up and down due to the transmission action of the thread.

[0055] When the jack screw 107 rotates upward, it pushes the pressure-bearing wooden block 106 upward.

[0056] Conversely, when the jack screw 107 rotates downward, the pressure-bearing wood 106 will move downward under the action of gravity.

[0057] It is known that the buoyancy-stopping effect is best when the distance between the top of the pressure-bearing timber 106 and the inclined plate 2 of the cabin roof is h. When the distance between the top of the pressure-bearing timber 106 and the inclined plate 2 of the cabin roof reaches the required distance h, the jack screw 107 is stopped from rotating.

[0058] When the position of the pressure-bearing timber 106 needs to be adjusted laterally, the adjusting plate 1054 is rotated. The adjusting plate 1054 drives the adjusting bolt 1052 to move. The adjusting bolt 1052 and the spring 109 drive the pressure-bearing timber 106 to move laterally. When it moves to the desired position, the rotation of the adjusting plate 1054 stops.

[0059] After the position of the pressure-bearing wood 106 is fixed, resin is injected into the contact surface between the pressure-bearing wood 106 and the top plate 102 through the resin inlet hole. After the resin has completely solidified, the jack screw 107 and the adjusting bolt 1052 are removed from the anti-floating component 1 to prevent the anti-floating component 1 from damaging other components due to the hardness of the jack screw 107 and the adjusting bolt 1052 during operation.
