Technical Field

[0001] This utility model relates to the field of cargo ship technology, and in particular to a sway-damping bulkhead assembly, a liquid cargo tank, and a cargo ship. Background Technology

[0002] With the development of shipping, liquid cargo tanks for transporting liquid media have gradually become larger to accommodate more liquid media, thereby effectively improving the efficiency of liquid media transportation and reducing the cost of cargo transportation.

[0003] However, as the size of the liquid cargo tank increases and the liquid medium loading rate increases, the liquid medium will slosh and exert an impact force on the cargo ship when transporting liquid medium in the liquid cargo tank, thereby affecting the ship's initial stability and making the ship prone to capsizing. Utility Model Content

[0007] In this embodiment, the bending member includes a first connecting portion, at least one bending portion, and a second connecting portion. One end of the first connecting portion is connected to the sway control bulkhead, and the other end of the first connecting portion is connected to the bending portion. The bending portion is bent to form a longitudinally arranged opening. The second connecting portion extends longitudinally, and one end of the second connecting portion is connected to the bending portion. The peripheral wall of the other end of the second connecting portion is attached to and connected to the support member.

[0008] In this embodiment, the bending member includes a plurality of bending portions, which are connected sequentially in the transverse direction; any two adjacent bending portions within the same bending member have opposite opening directions.

[0009] In this embodiment, the opening directions of any two adjacent bent members near the opening of the support member are opposite.

[0010] In this embodiment, the oscillation control bulkhead includes a panel and two reinforcing plates. The panel extends laterally and has a plurality of spaced liquid passage holes. The two reinforcing plates extend along the two sides of the panel laterally and are fixedly connected to the panel. The side of the two reinforcing plates opposite to the panel is respectively connected to the two connecting structures.

[0011] In this embodiment, the diameter of the liquid passage hole at least partially close to the reinforcing plate is smaller than the diameter of the liquid passage hole in the middle of the panel.

[0012] In this embodiment, the oscillation control chamber wall further includes multiple reinforcing ribs, which are fixedly connected to the panel and spaced apart from the liquid passage holes. The multiple reinforcing ribs are cross-connected to form a grid.

[0013] In this embodiment, both vertical ends of the reinforcing plate extend beyond the panel; The oscillation control bulkhead also includes four triangular corner portions, which are respectively located at the corners where the panel connects to the two reinforcing plates.

[0025] In related technologies, cargo ships may be equipped with liquid cargo tanks to contain and transport liquid media.

[0026] In some embodiments, the liquid cargo tanks in a cargo ship may be liquid storage tanks, which may include a cylinder and end caps disposed at both ends of the cylinder.

[0027] For ease of understanding and description, the length direction of the liquid cargo tank will be referred to as the longitudinal direction below, the width direction of the liquid cargo tank as the transverse direction below, and the height direction of the liquid cargo tank as the transverse direction below.

[0028] Figure 1 This is a schematic diagram of the structure of the anti-sloshing bulkhead assembly of this utility model when it is installed inside the liquid cargo tank. Figure 2 yes Figure 1 Sectional view at point AA.

[0029] See Figure 1 and Figure 2 This application provides a sloshing bulkhead assembly 20, which can be housed in a liquid cargo tank 1 for sloshing liquid media, thereby ensuring the safety and reliability of the liquid cargo tank 1 during ship operation.

[0030] The sloshing-damping bulkhead assembly 20 includes a support member 300, a sloshing-damping bulkhead 500, and two connecting structures 400. The outer periphery of the support member 300 is used to connect to the inner periphery of the liquid cargo tank 1, and the support member 300 has a liquid cargo passage 340 inside. The sloshing-damping bulkhead 500 is disposed within the liquid cargo passage 340, and its two lateral sides are connected to the inner periphery of the support member 300. The two connecting structures 400 are respectively disposed on opposite lateral sides of the sloshing-damping bulkhead 500. The connecting structures 400 include multiple bent members 410, which are arranged at intervals along the circumference of the support member 300. One end of each bent member 410 is connected to the sloshing-damping bulkhead 500, and the other end is connected to the support member 300. Each bent member 410 includes at least one longitudinally bent portion 412, allowing it to elastically deform so that the sloshing-damping bulkhead 500 can reduce the sloshing kinetic energy of the liquid medium.

[0031] When a cargo ship is transporting a liquid medium, the liquid medium will slosh within the cargo tank 1. At this time, the sloshing bulkhead assembly 20 is used to slosh the liquid medium. On the one hand, the sloshing bulkhead assembly 20 is used to separate the liquid medium to impede its flow; on the other hand, when the sloshing bulkhead 500 is impacted by the liquid medium, the multiple bending members 410 on both sides of the sloshing bulkhead 500 can elastically deform and return to their original position, thereby enabling the sloshing bulkhead 500 to periodically vibrate elastically to reduce the sloshing kinetic energy of the liquid medium, prevent damage to the cargo tank 1 under the impact of the liquid medium, and improve the safety and reliability of the liquid medium during transportation.

[0032] See Figure 1 and Figure 2 In this embodiment, the sway-controlling bulkhead assembly 20 includes a support member 300, which is used to connect the liquid cargo tank 1 and the connecting structure 400 so that the sway-controlling bulkhead 500 is connected to the liquid cargo tank 1 through the connecting structure 400.

[0033] The support member 300 includes a web 310 and a support cylinder 320. Both the web 310 and the support cylinder 320 extend in a ring shape along the circumference of the cargo tank 1. The web 310 is vertically connected to the inner circumferential wall of the cargo tank 1. The support cylinder 320 is located inside the web 310 and is fixedly connected to the web 310. The side of the support cylinder 320 facing away from the web 310 is connected to the connecting structure 400.

[0034] After bearing the load, the connecting structure 400 transfers the load to the support cylinder 320 and the web plate 310. The support cylinder 320 and the web plate 310 can evenly distribute the load before transferring it to the bulkhead of the liquid cargo tank 1, thereby preventing the bulkhead of the liquid cargo tank 1 from being damaged due to excessive local pressure, and effectively ensuring the safety and reliability of the liquid cargo tank 1.

[0035] See Figure 1 and Figure 2In this embodiment, at least one flow hole 311 is provided at the top and bottom of the web 310. The flow hole 311 at the top of the web 310 is used for gas flow to avoid the top of the liquid cargo tank 1 being divided into multiple sealed spaces, which would result in different pressures and ensure that the tank wall of the liquid cargo tank 1 is uniformly pressurized.

[0036] The flow hole 311 at the bottom of the web 310 is used to flow liquid medium, so as to avoid liquid medium remaining in the liquid cargo tank 1 when unloading, improve the space utilization of the liquid cargo tank 1, and reduce the transportation cost of the liquid cargo tank 1.

[0037] In some embodiments, the top of the web 310 may be provided with a plurality of flow holes 311, which are spaced apart circumferentially along the web 310 to improve gas flow efficiency.

[0038] In some embodiments, the bottom of the web 310 may be provided with a plurality of flow holes 311, which are spaced apart circumferentially along the web 310 to improve the flow efficiency of the liquid medium.

[0039] See Figure 1 and Figure 2 In this embodiment, the support member 300 further includes a plurality of support plates 330. The support plates 330 extend radially along the web 310 to improve the reliability and stability of the support member 300.

[0040] In some embodiments, a support plate 330 is disposed on the outside of a plurality of flow holes 311 at the top of the web 310 to enhance the structural strength and reliability of the web 310.

[0041] In some embodiments, the plurality of support plates 330 include a first support plate 330 and a second support plate 330. The first support plate 330 connects the web plate 310 and the bulkhead of the cargo tank 1. The second support plate 330 connects the web plate 310 and the support cylinder 320. Some of the first support plates 330 and some of the second support plates 330 can be arranged alternately in sequence, thereby improving the structural strength and stability of the support member 300.

[0042] In some embodiments, the support plate 330 is triangular in shape, thereby effectively improving the structural strength and load-bearing capacity of the support plate 330 itself.

[0043] Figure 4 This is a structural schematic diagram of two adjacent bent parts of this utility model.

[0044] See Figure 1 , Figure 2 and Figure 4In this embodiment, the sway-damping bulkhead assembly 20 further includes two connecting structures 400 connected to the support cylinder 320 and the sway-damping bulkhead 500. The two connecting structures 400 are located on the lateral sides of the sway-damping bulkhead 500, respectively, to transfer the impact load borne by the sway-damping bulkhead 500 to the support cylinder 320, and then to the bulkhead of the liquid cargo tank 1 through the support cylinder 320 and the web 310.

[0045] Furthermore, the connecting structure 400 can undergo elastic deformation to absorb the kinetic energy of the swaying bulkhead 500 when it is subjected to impact, thereby reducing the sloshing kinetic energy of the liquid medium and improving the safety, reliability and stability of the swaying bulkhead assembly 20.

[0046] The two connecting structures 400 extend along the transverse edge of the sway-damping bulkhead 500 so that the load carried by the sway-damping bulkhead 500 can be evenly transferred to the support member 300 through the two connecting structures 400.

[0047] See Figure 1 , Figure 2 and Figure 4 In this embodiment, the connecting structure 400 includes a plurality of bent members 410. The plurality of bent members 410 are spaced apart circumferentially along the support cylinder 320. Each of the plurality of bent members 410 includes a first connecting portion 411, at least one bent portion 412, and a second connecting portion 413. One end of the first connecting portion 411 is connected to the sway control bulkhead 500, and the other end of the first connecting portion 411 is connected to the bent portion 412. The bent portion 412 is bent to form a longitudinally oriented opening 4121. The second connecting portion 413 extends longitudinally, one end of the second connecting portion 413 is connected to the bent portion 412, and the peripheral wall of the other end of the second connecting portion 413 is attached to and connected to the support cylinder 320.

[0048] When the sway-damping bulkhead 500 bears an impact load, the impact load is transmitted to the support cylinder 320 after passing through the first connecting part 411, the bending part 412, and the second connecting part 413. Furthermore, the peripheral wall of the second connecting part 413 is tightly fitted and fixedly connected to the support cylinder 320, thereby increasing the contact area between the second connecting part 413 and the support cylinder 320 and preventing damage due to excessive local pressure or tension between them.

[0049] Meanwhile, the longitudinally bent portion can undergo periodic elastic vibration to convert the absorbed elastic kinetic energy into vibrational kinetic energy, enabling the sway-damping bulkhead 500 to apply external force to the liquid medium, thereby further reducing the impact load and improving the reliability and stability of the sway-damping bulkhead assembly 20.

[0050] Furthermore, when the sway-damping bulkhead 500 applies external force to the liquid medium, it can also change the swaying frequency of the liquid medium, thereby avoiding resonance of the liquid medium.

[0051] In some embodiments, the bending member 410 extends radially along the support cylinder 320, thereby facilitating the support member 300 to uniformly transfer the impact kinetic energy of the sway block 500 to the support member 300, thereby improving the reliability and stability of the sway block assembly 20.

[0052] See Figure 1 , Figure 2 and Figure 4 In this embodiment, in the direction away from the axis of the support cylinder 320, the first connecting part 411 is arranged in an arc shape along the longitudinal direction to connect with the bending part 412, thereby further improving the kinetic energy absorbed and reduced by the bending part 410 during periodic elastic vibration, avoiding damage to the bending part 410 due to excessive local stress, and ensuring the stability and reliability of the bending part 410.

[0053] In some embodiments, the first connecting portion 411 can be an arc-shaped structure with an included angle of 90° in the horizontal plane. The tangent direction of the end of the first connecting portion 411 connected to the sway block 500 extends laterally, and the tangent direction of the end of the first connecting portion 411 connected to the bending portion 412 extends longitudinally, thereby improving the connection strength between the first connecting portion 411 and the bending portion 412, and facilitating the elastic deformation of the bending member 410 to fully absorb the impact load of the sway block 500.

[0054] In some embodiments, in the horizontal plane, the connection between the first connecting part 411 and the sway block 500 can be located on the center line of the sway block 500 extending laterally, so that the load borne by the sway block 500 can be evenly transmitted to the bending part 412 through the first connecting part 411, ensuring the reliability of the connection between the sway block 500 and the first connecting part 411.

[0055] See Figure 1 , Figure 2 and Figure 4 In this embodiment, the bending member 410 may include a first connecting portion 411, a bending portion 412, and a second connecting portion 413. The first connecting portion 411, the bending portion 412, and the second connecting portion 413 are connected sequentially, and the bending directions of the first connecting portion 411 and the bending portion 412 are opposite, so that the bending portion 412 can be adapted to the first connecting portion 411 to fully absorb the kinetic energy of the sway-damping bulkhead 500, thereby improving the reliability and stability of the bending member 410.

[0056] In some embodiments, the bending portion 412 can be a semi-circular structure with a bending angle of 180°, thereby reducing the effective deformation length of the bent part 410 through the structure of the first connecting portion 411 and the bending portion 412, increasing the rigidity of the bent part 410, and preventing the bent part 410 from breaking and being damaged due to low rigidity.

[0057] In some embodiments, the bending member 410 may include a first connecting portion 411, a plurality of bending portions 412, and a second connecting portion 413. The first connecting portion 411, the plurality of bending portions 412, and the second connecting portion 413 are connected sequentially. The plurality of bending portions 412 are connected end to end in a transverse direction, and the openings 4121 of any two adjacent bending portions 412 within the same bending member 410 have opposite directions, so that the plurality of bending portions 412 are connected to form a wave-shaped structure.

[0058] The bending direction of the bent portion 412 near the first connecting portion 411 is opposite to that of the first connecting portion 411, so that the bent portion 412 can be adapted to the first connecting portion 411 to fully absorb the kinetic energy of the sway block 500, thereby improving the reliability and stability of the bent part 410.

[0059] In this embodiment, the tangential direction of the end of the bent portion 412 connected to the second connecting portion 413 is in the same direction as the extension direction of the second connecting portion 413, thereby reducing the volume of the bent portion 410 while ensuring the load-bearing capacity and load reduction capacity of the bent portion 410.

[0060] See Figure 1 , Figure 2 and Figure 4 In this embodiment, the first connecting portion 411, the bent portion 412 and the second connecting portion 413 within the bent member 410 have a smooth transition.

[0061] In this embodiment, the oscillation control bulkhead assembly 20 includes a panel 510 and two reinforcing plates 520. The panel 510 extends laterally and has a plurality of spaced-apart liquid passage holes 511. The two reinforcing plates 520 extend along the two lateral edges of the panel 510 and are fixedly connected to the panel 510. The side of the two reinforcing plates 520 facing away from the panel 510 is respectively connected to the first connecting portion 411 in the two connecting structures 400.

[0062] Panel 510 can stop the liquid medium, thereby separating the liquid medium and reducing the impact kinetic energy of the liquid medium. Reinforcing plate 520 is connected to panel 510 and first connecting part 411 so that reinforcing plate 520 can evenly transfer the impact load borne by panel 510 to bending member 410, avoiding damage to panel 510 due to excessive local load, and improving the structural strength and reliability of sway control bulkhead 500.

[0063] See Figure 1In this embodiment, the panel 510 is provided with a plurality of spaced liquid passage holes 511. Some liquid medium can pass through the liquid passage holes 511 through the panel 510. On the one hand, it can reduce the impact load borne by the panel 510, and prevent the bending member 410 and the support member 300 from being damaged due to excessive load exceeding the yield limit, and prevent the structural connections in the swaying bulkhead assembly 20 from separating and being damaged. On the other hand, after some liquid medium on the longitudinal side of the panel 510 passes through the panel 510, it can impact some liquid medium on the other longitudinal side, thereby causing the liquid medium on the other longitudinal side to become disordered, disrupting the fixed frequency of the liquid medium on the other longitudinal side when it is shaking, and further reducing the impact kinetic energy of the liquid medium.

[0064] See Figure 1 In this embodiment, the diameter of the liquid passage hole 511 near the reinforcing plate 520 is smaller than that of the liquid passage hole 511 in the middle of the panel 510, so as to improve the structural strength at the connection between the panel 510 and the reinforcing plate 520, avoid damage to the panel 510 due to the low local compressive strength when bearing impact load, and improve the reliability, stability and safety of the sway control bulkhead 500.

[0065] In some embodiments, the diameter of the liquid passage holes 511 at least partially near the lateral ends of the reinforcing plate 520 may be smaller than the diameter of the liquid passage holes 511 in the middle of the panel 510, so as to improve the structural strength at the connection between the panel 510 and the reinforcing plate 520.

[0066] Figure 3 yes Figure 1 Enlarged view of the structure at point B in the middle.

[0067] See Figure 1 , Figure 2 and Figure 3 In this embodiment, both vertical ends of the reinforcing plate 520 extend beyond the panel 510. The turbulence bulkhead 500 also includes four triangular corner portions 530. The four corner portions 530 are respectively disposed at the corners where the panel 510 connects to the two reinforcing plates 520. The first sidewall of the corner portion 530 is tightly fitted and fixedly connected to the vertical end face of the panel 510, and the second sidewall of the corner portion 530 is tightly fitted and fixedly connected to the reinforcing plate 520; the third sidewall of the corner portion 530 is located between the panel 510 and the reinforcing plate 520 to connect the first sidewall and the second sidewall.

[0068] The corner portion 530 can effectively improve the connection strength between the panel 510 and the reinforcing plate 520, thereby preventing the panel 510 from being separated from the reinforcing plate 520 due to excessive load, and improving the safety, reliability and stability of the sway control bulkhead 500.

[0069] In some embodiments, the oscillation bulkhead 500 includes two corner portions 530 located on the upper side of the panel 510 and two corner portions 530 located on the lower side of the panel. The first sidewalls of the two corner portions 530 located on the upper side of the panel 510 are fixedly connected to the vertical upper surface of the panel 510, and the second sidewalls of the two corner portions 530 are respectively tightly fitted and fixedly connected to two reinforcing plates 520. The first sidewalls of the two corner portions 530 located on the lower side of the panel 510 are fixedly connected to the vertical lower surface of the panel 510, and the second sidewalls of the two corner portions 530 are respectively tightly fitted and fixedly connected to two reinforcing plates 520.

[0070] In some embodiments, the third sidewall of the corner portion 530 is arc-shaped, and the central angle of the third sidewall of the corner portion 530 is less than 90°, in order to disperse stress and improve structural toughness and impact resistance.

[0071] In some embodiments, there may be multiple panels 510, which are arranged vertically at intervals and extend laterally so that both sides of the panels 510 are connected to the reinforcing plate.

[0072] See Figure 1 and Figure 2 In this embodiment, the oscillation control bulkhead 500 also includes a plurality of reinforcing ribs 540, which are fixedly connected to the panel 510. The reinforcing ribs 540 are spaced apart from the liquid passage holes 511, and the plurality of reinforcing ribs 540 are cross-connected to form a grid, thereby further strengthening the structural strength and reliability of the panel 510. In addition, it can also improve the connection strength between the panel 510 and the reinforcing plate 520, ensuring the stability and safety of the oscillation control bulkhead 500.

[0073] See Figure 1 In this embodiment, the upper side of the sway-damping bulkhead 500 is spaced apart from the upper part of the support cylinder 320, forming an upper flow channel 341 between the sway-damping bulkhead 500 and the support cylinder 320. The lower side of the sway-damping bulkhead 500 is spaced apart from the lower part of the support cylinder 320, forming a lower flow channel 342 between the sway-damping bulkhead 500 and the support cylinder 320. The arrangement of the upper flow channel 341 and the lower flow channel 342 can reduce the volume of the sway-damping bulkhead assembly 20 while ensuring the sway-damping effect of the sway-damping bulkhead assembly 20, increasing the capacity of the liquid cargo tank 1, and reducing transportation costs.

[0074] In this embodiment, the sway-damping bulkhead assembly 20 can also be applied to liquid cargo storage tanks used in land transportation to ensure the safety and reliability of the liquid cargo storage tanks during transportation.

[0075] See Figures 1 to 4 When transporting liquid media in liquid cargo tank 1, the liquid media sloshes inside liquid cargo tank 1 and impacts the panel 510.

[0076] After bearing the impact load, the panel 510 transmits the load evenly to the bulkhead of the cargo tank 1 through the reinforcing plate 520, bending member 410, and support member 300. On the one hand, the sloshing bulkhead 500 can stop the flow of the liquid medium to reduce the sloshing kinetic energy of the liquid medium; on the other hand, under the action of multiple bending members 410, the sloshing bulkhead 500 achieves periodic elastic vibration, which can further reduce the impact load borne by the panel 510, change the natural frequency of the liquid medium sloshing, avoid resonance of the liquid medium, and ensure the safety and reliability of the sloshing bulkhead assembly 20.

[0077] Furthermore, in the longitudinal direction, a portion of the liquid medium on one side of the sway-damping bulkhead 500 can pass through the sway-damping bulkhead 500 to impact a portion of the liquid medium on the other side, causing the liquid medium on the other side to become turbulent, dissipating the swaying kinetic energy of the liquid medium, and ensuring the safety and reliability of the sway-damping bulkhead assembly 20.

[0078] See Figures 1 to 4 This application also provides a liquid cargo tank, comprising: a bulkhead and a sloshing bulkhead assembly 20 as described above. The bulkhead encloses a cargo space for containing a liquid medium. The sloshing bulkhead assembly 20 is housed within the cargo space, and a support member 300 is tightly fitted and fixedly connected to the bulkhead on its outer periphery. The sloshing bulkhead assembly 20 is used to slosh the liquid medium.

[0079] When a liquid cargo tank is transporting a liquid medium, the liquid medium sloshes within the cargo space. On one hand, the sloshing bulkhead assembly 20 can effectively stop the liquid medium, achieving physical separation of the liquid medium and thus reducing the impact kinetic energy of the liquid medium. On the other hand, the sloshing bulkhead 500 can achieve periodic elastic vibration to change the fixed frequency of the liquid medium's sloshing and can cause the liquid medium to become turbulent, thereby reducing the impact kinetic energy of the liquid medium, preventing the liquid medium from exacerbating the rolling amplitude of the cargo ship, and improving the stability and maneuverability of navigation.

[0080] See Figures 1 to 4 This application also provides a cargo vessel, which includes: a hull. The hull includes a liquid cargo tank 1.

[0081] The liquid cargo tank 1 includes a bulkhead and any of the above-described sloshing bulkhead assemblies 20. The bulkheads enclose a cargo space for containing a liquid medium. The sloshing bulkhead assembly 20 is housed within the cargo space, and the outer periphery of the support member 300 is tightly fitted and fixedly connected to the bulkhead. The sloshing bulkhead assembly 20 is used to slosh the liquid medium.

[0082] When a cargo ship is transporting a liquid medium, the liquid medium sloshes within the cargo tank 1. On one hand, the sloshing bulkhead assembly 20 can effectively stop the liquid medium, achieving physical separation of the liquid medium and thus reducing the impact kinetic energy of the liquid medium. On the other hand, the sloshing bulkhead 500 can achieve periodic elastic vibration to change the fixed frequency of the liquid medium sloshing and can cause the liquid medium to become turbulent, thereby reducing the impact kinetic energy of the liquid medium, preventing the liquid medium from exacerbating the swaying amplitude of the cargo ship, and improving the stability and maneuverability of navigation.

[0083] In some embodiments, the cargo vessel and its liquid cargo tank 1 can both extend longitudinally.

[0084] In other embodiments, the cargo ship may extend laterally and may have multiple longitudinally extending liquid cargo tanks 1, each of which is equipped with a sway-damping bulkhead assembly 20.

[0085] In some embodiments, multiple sloshing-damping bulkhead assemblies 20 may be provided in the same liquid cargo tank 1 to divide the liquid cargo tank 1 into multiple parts, thereby effectively reducing the sloshing kinetic energy of the liquid medium and improving the stability, reliability and safety of the liquid cargo tank 1.

[0086] Although this application has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since this application can be embodied in many forms without departing from the spirit or essence of the utility model, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims. Therefore, all variations and modifications falling within the scope of the claims or their equivalents should be covered by the appended claims.
