Description

Technical Field

[0001] This invention relates to the field of liquefied gas transportation, and mainly to a sway-stopping wall assembly and a storage tank. Background Technology

[0002] During the transportation of liquefied gas (LPG) in marine tanks, the internal liquid inevitably sloshes. To reduce the impact of this sloshing on the tank structure, shorten the free surface area, and alter the sloshing period, anti-sloshing walls are typically installed on the inner wall of the tank. These anti-sloshing walls are perforated bulkheads connected to reinforcing rings inside the tank, designed to reduce the impact force generated by violent sloshing of the liquid and to change the tank's vibration period.

[0003] The existing connection between the sloshing wall and the tank body is a rigid connection. Therefore, during use, due to the impact of the liquid on the sloshing wall, fatigue cracks are easily generated at the connection point between the sloshing wall and the tank body, leading to connection failure. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a sway-stopping wall assembly that can improve the stability of the connection position between the sway-stopping wall and the tank body;

[0005] Another objective is to provide a storage tank that can reduce the impact of violent shaking of the internal liquid on the tank body and improve the service life of the storage tank.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An anti-sloshing wall assembly includes an anti-sloshing wall body and an elastic connector, one end of which is slidably connected to the anti-sloshing wall body and the other end is fixedly connected to the inner wall of the tank.

[0008] In some embodiments of this application, the elastic connector includes an elastic element, a long panel, and a connecting plate. One end of the elastic element is fixedly connected to the inner wall of the tank, and the other end is fixedly connected to the long panel. The connecting plate is connected to the long panel, and one end protrudes from the surface of the long panel. The connecting plate is slidably connected to the anti-sloshing wall body. The direction in which the elastic element can elastically deform is the same as, perpendicular to, or at an angle to the direction in which the anti-sloshing wall body can slide relative to the connecting plate.

[0009] In some embodiments of this application, the number of elastic elements is multiple, and the multiple elastic elements are spaced apart along the length direction of the long panel.

[0010] In some embodiments of this application, the elastic element is a U-shaped spring plate, the direction in which the elastic element can elastically deform is towards the anti-sway wall body, and the openings of two adjacent spring plates face opposite directions.

[0011] In some embodiments of this application, the direction in which the connecting plate protrudes from the surface of the elongated panel is the same as the direction in which the sway-stopping wall body can move relative to the connecting plate. The connecting plate is provided with screw holes, and the sway-stopping wall body is provided with elongated holes. The length direction of the elongated holes is the same as the direction in which the connecting plate protrudes from the elongated panel. The sway-stopping wall assembly also includes screws that pass through the elongated holes and the screw holes to connect with the connecting plate and the sway-stopping wall respectively, and the screws can slide relative to the length direction of the elongated holes.

[0012] In some embodiments of this application, the connecting plates are connected in multiple pieces, and the multiple connecting plates are spaced apart along the length direction of the long panel; each connecting plate is provided with multiple screw holes, the number of elongated holes on the anti-sway wall body matches the number of screw holes, and the position of the elongated holes corresponds one-to-one with the position of the screw holes.

[0013] In some embodiments of this application, the distance between the long panel and the anti-sway wall body is greater than or equal to 20 mm.

[0014] In some embodiments of this application, the sway-damping wall body has relief holes and flow holes; the sway-damping wall body includes a sway-damping wall plate, horizontal trusses, vertical trusses, and reinforcing members. There are multiple horizontal trusses, which are spaced apart on the sway-damping wall plate. There are also multiple vertical trusses, which are spaced apart on the sway-damping wall plate. The reinforcing members are located in the middle of the sway-damping wall plate and are situated on the horizontal trusses.

[0015] A storage tank includes a tank body and the aforementioned anti-sloshing wall assembly, the anti-sloshing wall assembly being installed inside the tank body.

[0016] In some embodiments of this application, the top surface of the anti-sloshing wall body is at a distance from the top of the tank, and the bottom surface of the anti-sloshing wall body is at a distance from the bottom of the tank; both sides of the anti-sloshing wall body are connected to the tank through the elastic connector.

[0017] Beneficial effects: The anti-sloshing wall assembly includes an anti-sloshing wall body and an elastic connector. One end of the elastic connector is slidably connected to the anti-sloshing wall body, and the other end is fixedly connected to the inner wall of the tank. Therefore, when the liquid in the tank sloshes and impacts the anti-sloshing wall body, relative movement occurs between the anti-sloshing wall body and the tank, or the elastic connector is compressed, or both relative movement between the anti-sloshing wall body and the tank and compression of the elastic connector occur. This buffers a certain amount of impact force, preventing stress concentration at the connection point between the anti-sloshing wall body and the tank, which could lead to fatigue cracks at the connection point. This improves the stability of the connection and extends the service life of the anti-sloshing wall assembly.

[0018] The storage tank includes a tank body and a slug wall assembly, which reduces the impact of liquid on the inner wall of the tank. The slug wall assembly includes a slug wall body and an elastic connector. The slug wall body is connected to the tank body through the elastic connector, which avoids stress concentration at the connection point between the slug wall body and the tank body, which could lead to fatigue cracks at the connection point and cause the slug wall assembly to fail. This improves the stability of the connection point and extends the service life of the storage tank. Attached Figure Description

Detailed Implementation

[0027] This invention provides a sway-damping wall assembly and a storage tank. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the invention and are not intended to limit the scope of protection of the invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows for communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0030] When transporting liquids, they need to be placed in containers such as storage tanks. Liquids will slosh during transportation. For example, when transporting natural gas (which is in a low-temperature liquid state during transportation) by ship, the ship will slosh when it is sailing at sea and there are waves. This will cause the natural gas to slosh and impact the inner wall of the storage tank on the ship. Over long-term use, the storage tank is prone to damage.

[0031] See Figure 1 , Figure 2 and Figure 3 This application provides a storage tank, including a tank body 200 and an anti-sloshing wall assembly, which is installed inside the tank body 200. When there is liquid inside the tank body 200 and the liquid sloshes, the anti-sloshing wall assembly blocks the sloshing of the liquid, thereby reducing the sloshing impact of the liquid on the tank body 200, shortening the free liquid level, changing its sloshing period, weakening the impact on the tank body 200, and improving the service life of the storage tank.

[0032] Inside the tank 200, multiple spaced reinforcing rings are typically installed. These reinforcing rings are usually made of T-shaped profiles, angle steel, or square tubing and are welded to the inner wall of the tank 200 to improve its structural strength. Multiple anti-sloshing wall assemblies can be installed at intervals, so that when liquid sloshes between two adjacent anti-sloshing wall assemblies, it impacts the two anti-sloshing wall assemblies, thus reducing the impact on the tank 200. Alternatively, a single anti-sloshing wall assembly can be installed in the middle of the tank 200, so that when liquid sloshes inside the tank 200, some of the liquid impacts the anti-sloshing wall assembly, thus reducing the impact on the tank 200.

[0033] The reinforcing ring, after being welded to the inner wall of the tank 200, forms a structure protruding from the inner wall of the tank 200. This structure can be used for connection with the anti-sloshing wall assembly, making the connection easier. The plane of the anti-sloshing wall assembly is arranged along the cross-sectional direction of the tank 200, and the outer side of the anti-sloshing wall assembly is connected to the reinforcing ring on the inner wall of the tank 200. Therefore, when liquid impacts the anti-sloshing wall assembly, it is less likely to cause damage to the tank 200, thus improving the service life of the storage tank. In other embodiments, the anti-sloshing wall assembly can also be arranged on the longitudinal section of the tank 200.

[0034] The top surface of the anti-sloshing wall assembly is spaced from the top of the tank 200, and the bottom surface of the anti-sloshing wall body 1 is spaced from the bottom of the tank 200. Therefore, the anti-sloshing wall assembly does not completely obstruct the interior of the tank 200, allowing liquid to circulate freely throughout the tank 200. This facilitates the filling and emptying of liquid from the tank 200, reduces the weight of the anti-sloshing wall body 1, and consequently reduces the weight of the storage tank. Preferably, the anti-sloshing wall assembly is located within 30%-70% of the internal height of the tank 200, ensuring sufficient space for liquid to pass through at both the bottom and top of the anti-sloshing wall assembly, and providing a good buffering effect for the liquid.

[0035] See Figure 1 , Figure 2 and Figure 3 The anti-sloshing wall assembly includes an anti-sloshing wall body 1 and an elastic connector 2. One end of the elastic connector 2 is slidably connected to the anti-sloshing wall body 1, and the other end is fixedly connected to the inner wall of the tank 200. Therefore, when the liquid inside the tank 200 sloshes and impacts the anti-sloshing wall body 1, the elastic connector 2 undergoes elastic deformation, or relative movement occurs between the anti-sloshing wall body 1 and the elastic connector 2, or relative movement occurs between the anti-sloshing wall body 1 and the elastic connector 2, and the elastic connector 2 undergoes elastic deformation, thereby reducing the impact of the liquid on the inside of the tank 200 and extending the service life of the storage tank.

[0036] Among them, the elastic connector 2 is connected to the anti-sloshing wall body 1 to form an anti-sloshing wall assembly. When the liquid impacts the anti-sloshing wall body 1, the elastic connector 2 can play a buffering role, thereby reducing the stress on the connection between the elastic connector 2 and the anti-sloshing wall body 1 and the connection between the elastic connector 2 and the tank body 200. Therefore, it can improve the service life of the anti-sloshing wall body 1 and extend the service life of the storage tank.

[0037] Specifically, the elastic connector 2 includes an elastic element 21, a long panel 22, and a connecting plate 23. One end of the elastic element 21 is fixedly connected to the inner wall of the tank 200, and the other end is connected to the long panel 22. The elastic element 21 is welded to the inner wall of the tank 200 and to the long panel 22. The long panel 22 has a connecting plate 23 connected to the side facing away from the elastic element 21. The connecting plate 23 protrudes from the surface of the long panel 22, and the connecting plate 23 is slidably connected to the anti-sway wall body 1, allowing the anti-sway wall body 1 to move relative to the long panel 22.

[0038] See Figure 2 and Figure 3 In one embodiment, the connecting plate 23 extends toward the anti-slip wall body 1, and the length direction of the elongated hole 111 faces the anti-slip wall body 1. This allows the elastic member 21 to deform elastically in the same direction as the anti-slip wall body 1 can move relative to the long panel 22. Furthermore, the anti-slip wall body 1 has a certain sliding space, and its volume and weight are reduced. Therefore, the anti-slip wall body 1 can only compress and deform the elastic member 21 after sliding a relatively long distance relative to the long panel 22, further reducing the impact force.

[0039] In other words, when liquid impacts the anti-sloshing wall body 1, the anti-sloshing wall body 1 first moves relative to the tank 200 to buffer a certain amount of impact force. When the distance moved by the anti-sloshing wall body 1 is greater than the maximum distance that the anti-sloshing wall body 1 and the tank 200 can slide, the elastic connector 2 is compressed to further absorb the impact force. Therefore, stress concentration at the connection position between the anti-sloshing wall body 1 and the tank 200 is avoided, which would lead to fatigue cracks at the connection position. This improves the stability of the connection and extends the service life of the anti-sloshing wall assembly.

[0040] Both sides of the anti-sloshing wall body 1 are connected to elastic connectors 2, and both sides of the anti-sloshing wall body 1 are connected to the inner wall of the tank 200 through the elastic connectors 2. That is to say, the anti-sloshing wall body 1 is connected to the reinforcing ring through the elastic connectors 2, so the anti-sloshing wall body 1 will not damage the structure of the tank 200 when buffering the liquid.

[0041] By setting the elastic element 21 and sliding the long panel 22 with the anti-sway wall body 1, an inner and outer two-layer buffer structure is formed, which realizes a safer and more reliable connection between the anti-sway wall body 1 and the tank 200, and can ensure the long-term working performance of the anti-sway wall body 1.

[0042] See Figure 6In one embodiment, the direction in which the elastic member 21 can elastically deform is perpendicular to the direction in which the connecting plate 23 protrudes from the surface of the long panel 22. That is, the direction in which the elastic member 21 can elastically deform is perpendicular to the direction in which the sway-damping wall body 1 can slide relative to the connecting plate 23. For example, the direction in which the elastic member 21 can elastically deform is towards the inside of the tank 200, that is, towards the inside of the plane where the sway-damping wall body 1 is located. The direction in which the connecting plate 23 protrudes relative to the long panel 22 is the length direction of the tank 200. That is, the direction in which the sway-damping wall body 1 can slide relative to the connecting plate 23 is the length direction of the tank 200, that is, the direction perpendicular to the plane where the sway-damping wall body 1 is located. Therefore, the relative sliding between the elastic member 21 and the sway-damping wall body 1 and the long panel 22 is used to buffer the impact forces in two different directions.

[0043] For example, in a cylindrical tank 200, the elastic deformation direction of the elastic element 21 is radial to the tank 200, and the direction in which the sway barrier body 1 can slide relative to the connecting plate 23 is axial to the tank 200. When liquid impacts the sway barrier body 1 axially along the tank 200, the sway barrier body 1 moves relative to the connecting plate 23. During this movement, the sway barrier body 1 consumes the liquid's impact force, reducing the impact of the liquid on the inner wall of the tank 200. When liquid impacts the sway barrier body 1 radially along the tank 200, the sway barrier body 1 moves radially. During this movement, the sway barrier body 1 consumes the liquid's impact force, and through the elastic deformation of the elastic element 21, it prevents the sway barrier body 1 from impacting the inner wall of the tank 200. In other embodiments, the shape of the tank 200 is not limited.

[0044] See Figure 7 In one embodiment, the direction in which the elastic member 21 can elastically deform forms an angle with the direction in which the anti-slip wall body 1 can slide relative to the connecting plate 23. That is, the direction in which the elastic member 21 can elastically deform and the direction in which the anti-slip wall body 1 can slide relative to the connecting plate 23 are between the same and perpendicular, thus reducing impact forces from multiple directions. For example, in a cylindrical tank 200, the direction of elastic deformation of the elastic member 21 is radial to the tank 200, and the direction of extension of the connecting plate 23 forms an angle with both the axial and radial directions of the tank 200. When liquid impacts the anti-slip wall body 1 radially along the tank 200, the anti-slip wall body 1 and the connecting plate 23 move relative to each other, and the elastic member 21 undergoes elastic deformation. When liquid impacts the anti-slip wall body 1 axially along the tank 200, the anti-slip wall body 1 and the connecting plate 23 move relative to each other, preventing the anti-slip wall body 1 from impacting the inner wall of the tank 200. In other embodiments, the shape of the tank 200 is not limited.

[0045] Since the impact force of the liquid sloshing inside the tank 200 is not unique, the direction in which the elastic element 21 can elastically deform is perpendicular to or at an angle to the direction in which the anti-sloshing wall body 1 can slide relative to the long panel 22, so that it can buffer the impact of the liquid in different directions.

[0046] See Figure 3 and Figure 4 The long panel 22 is vertically arranged, meaning that it is arranged vertically at both ends along its length, including vertical, inclined, and arc-shaped configurations. Multiple elastic elements 21 are spaced apart along the length of the long panel 22. These elastic elements 21 are distributed and connected to the sway barrier body 1 on both sides of its height, thus dispersing the impact force on the sway barrier body 1, improving the stability between the sway barrier body 1 and the tank 200. Furthermore, the multiple distributed support points support the sway barrier body 1, resulting in a more balanced force distribution.

[0047] The elastic element 21 is a U-shaped spring plate with the openings of adjacent spring plates facing opposite directions. That is, the spring plates are arranged alternately around the edge of the long panel 22, allowing the elastic element 21 to undergo elastic deformation in multiple directions, including front-back, inside-out, and so on. This enables the sway-damping wall body 1 to buffer in these directions. When the sway-damping wall body 1 receives an impact force in the front-back direction, the deformation directions of adjacent spring plates are exactly opposite, allowing the elastic forces of adjacent spring plates to cooperate and achieve a better buffering effect. The sway-damping wall body 1 is located on the cross-section of the tank body 200. The front-back direction refers to the direction perpendicular to the plane where the sway-damping wall body 1 is located; the inside-out direction refers to the direction from the side wall of the tank body 200 towards the sway-damping wall body 1.

[0048] In the above, the spring plates are arranged in an alternating pattern around the edge of the long panel 22, so that the spring plates are arranged in a three-dimensional space rather than on the same surface. Therefore, when subjected to impact force, the spring plates interact with each other, which can improve the stress strength of the elastic element 21.

[0049] In other embodiments, the elastic element 21 can be a tension spring, with one axial end connected to the long panel 22 and the other end connected to the tank body 200. The tension spring can deform both axially and radially, and therefore can absorb impact forces from multiple directions.

[0050] See Figure 3 , Figure 4 and Figure 5The connecting plate 23 has screw holes 231, and the sway barrier body 1 has an elongated hole 111, also called a waist-shaped hole, which has a certain length. The sway barrier assembly also includes screws 24, which pass through the elongated hole 111 and the screw holes 231, and the screws 24 can slide relative to the length of the elongated hole 111, thereby realizing a slidable connection between the long panel 22 and the sway barrier body 1. This also makes the installation process between the sway barrier body 1 and the tank 200 more flexible and convenient, reducing the requirements for the assembly process.

[0051] In one embodiment of this application, the elongated panel 22 is formed with the same side shape as the sway barrier body 1, such that the distance between the elongated panel 22 and the side of the sway barrier body 1 is equal, and the distance between them is greater than or equal to the length of the elongated hole 111. Therefore, the sway barrier body 1 will not collide with the elastic member 21 during movement. Preferably, the distance L between the elongated panel 22 and the sway barrier body 1 is greater than or equal to 20 mm.

[0052] In some embodiments of this application, fillet welds are used between the long panel 22 and the connecting plate 23, between the long panel 22 and the spring plate, and between the spring plate and the tank body 200. The spring plate is a U-shaped buffer bridge made of steel plate.

[0053] Along the length of the long panel 22, multiple connecting plates 23 are spaced apart. Therefore, there are multiple connection points between the sway-damping wall body 1 and the long panel 22, and these connection points are distributed to better reduce stress at the connection points and facilitate maintaining the balance of the sway-damping wall body 1. For example: in Figure 1 In the anti-sway wall assembly shown, each side of the anti-sway wall body 1 has four connecting plates 23 spaced apart on the long panel 22.

[0054] Each connecting plate 23 is provided with multiple screw holes 231. The number of elongated holes 111 on the sway barrier body 1 matches the number of screw holes 231. The position of the elongated holes 111 corresponds one-to-one with the screw holes 231. The screw 24 includes a bolt 241, a nut 242 and a washer 243. The bolt 241 passes through the washer 243, the elongated hole 111 and the screw hole 231 and is connected to the nut 242 to realize the connection between the connecting plate 23 and the sway barrier body 1.

[0055] In the embodiments of this application, screw holes 231 are provided in the middle region of the connecting plate 23, and each connecting plate 23 is connected to the anti-sway wall body 1 by six sets of screws 24 to ensure the strength of the connection position.

[0056] Bolt 241, nut 242 and washer 243 are all made of cryogenic materials, such as Invar alloy and austenitic stainless steel, which ensures their strength even in cryogenic natural gas liquids.

[0057] See Figure 3 The anti-sloshing wall body 1 has relief holes and flow holes, which not only prevent the movement of liquid but also reduce the weight of the anti-sloshing wall body 1. The anti-sloshing wall body 1 includes an anti-sloshing wall panel 11, horizontal trusses 12, vertical trusses 13, and reinforcing members 14. There are multiple horizontal trusses 12, which are spaced apart on the anti-sloshing wall panel 11. There are also multiple vertical trusses 13, which are spaced apart on the anti-sloshing wall panel 11. The reinforcing members 14 are located on the horizontal trusses 12 in the middle of the anti-sloshing wall panel 11, forming a plate frame structure. Since the reinforcing members 14 are located on the horizontal trusses 12 in the middle of the anti-sloshing wall panel 11, there are no reinforcing members 14 on the upper and lower sides of the anti-sloshing wall panel 11. The strength of the anti-sloshing wall panel 11 at the upper and lower sides is enhanced by the vertical trusses 13, thus reducing the weight of the anti-sloshing wall body 1.

[0058] In other words, the horizontal truss 12, the vertical truss 13, and the stiffener 14 form a grid-like skeleton, which is welded to the plate-shaped sway-damping wall 11, so that the sway-damping wall 11, the horizontal truss 12, the vertical truss 13, and the stiffener 14 are integrated into one unit, forming a sway-damping wall body 1 capable of withstanding large impact forces. The sway-damping wall 11 has relief holes and flow holes, allowing liquids on the front and rear sides of the sway-damping wall body 1 to communicate through these holes.

[0059] When the horizontal truss 12 and the vertical truss 13 are made of square tubes, horizontal flow holes are formed inside the horizontal truss 12 and vertical flow holes are formed inside the vertical truss 13. Therefore, when liquid impacts the anti-sloshing wall body 1, the anti-sloshing wall body 1 can achieve a buffering effect on the liquid.

[0060] In the above, the sway-stopping wall panel 11, the horizontal truss 12, the vertical truss 13 and the stiffener 14 are all connected by welding. Therefore, there are no stiffeners 14 on the upper and lower sides of the sway-stopping wall panel 11, which also reduces the amount of welding work.

[0061] In the embodiments of this application, the shape of the anti-sloshing wall body 1 matches the cross-sectional shape of the tank body 200, for example... Figure 1 In the middle, the tank body 200 is a horizontal double-eared tank. Two identical anti-sway wall bodies 1 form a structure that matches the cross-section of the horizontal double-eared tank, which reduces the weight of each anti-sway wall body 1 and facilitates installation.

[0062] In other embodiments, the single-piece anti-sloshing wall body 1 can also be formed into a structure that matches the horizontal double-eared jar.

[0063] In other embodiments, the tank 200 can be cylindrical, cuboid, etc., and the anti-sloshing wall body 1 corresponds to the cross-sectional shape of the tank 200.

[0064] The purpose of matching the shape of the anti-sloshing wall body 1 with the cross-sectional shape of the tank 200 is to make the distance between the anti-sloshing wall body 1 and the inner wall of the tank 200 equal, so that the specifications of each elastic element 21 of the elastic connector 2 are the same, the specifications of each connecting plate 23 are the same, and the dimensions of each part of the long panel 22 are the same. During installation, there is no need to distinguish the direction of the long panel 22, nor is it necessary to distinguish the specifications of the elastic element 21 and the connecting plate 23, which facilitates installation.

[0065] In other embodiments, the shape of the anti-sloshing wall body 1 may not match the cross-sectional shape of the tank 200, as long as the anti-sloshing wall body 1 can be installed inside the tank 200.

[0066] It should be noted that this application uses the transportation of natural gas by transport ship as an example for illustration, and does not limit the storage tank in this application to only be used for storing natural gas, but can also be used to store other liquids, such as oil, etc. The mode of transportation is not limited to shipping, but can also be other modes such as vehicle transportation.

[0067] It is understood that those skilled in the art can make equivalent substitutions or changes to the technical solution and inventive concept of the present invention, and all such changes or substitutions should fall within the protection scope of the present invention.
