One end of the support column is connected to the spherical shell, and the other end of the support column can be fixed to the ground. Through the above implementation method, the spherical shell can be installed on the ground through the support column.

[0004] In related technologies, the connection strength at the joint between the spherical shell and the support column is poor, which can lead to a decrease in the safety performance of the spherical tank. Summary of the Invention

[0005] This application provides a spherical tank structure and processing method, which can solve the problem of poor connection strength at the connection between the spherical shell and the support column, which leads to a decrease in the safety performance of the spherical tank.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] In a first aspect, this application provides a spherical tank structure, comprising:

[0008] Spherical tank body;

[0009] The first support component has a first surface and a second surface disposed opposite to each other. The first support component is welded around the outside of the spherical tank body. The first surface is fitted to the outer peripheral wall of the spherical tank body to form an annular reinforcing structure on the outside of the spherical tank body.

[0010] The second support component is welded to the second surface;

[0011] The support column is welded to the second support assembly and to the second surface;

[0012] The reinforcing member has one end welded to the first support assembly and the other end welded to the column.

[0013] In some embodiments, the first surface and the spherical tank body are welded together by double-sided full penetration welding.

[0014] In some embodiments, the first surface and the spherical tank body are welded together by a double-sided full penetration weld.

[0015] The weld seam between the first surface and the spherical tank body is ground and rounded.

[0016] And / or, non-destructive testing is performed on the surface of the weld between the first surface and the spherical tank body.

[0017] In some embodiments, the first support assembly includes a plurality of first support members, which are arranged sequentially at intervals along the circumferential direction of the spherical tank body.

[0018] The second support component includes multiple second support members, and the multiple second support members are configured in a one-to-one correspondence with the multiple first support members;

[0019] There are multiple pillars, and each pillar and multiple second support components are configured in a one-to-one correspondence.

[0020] There are multiple reinforcing components, and each reinforcing component corresponds to a different support column.

[0021] In some embodiments, along the height direction of the spherical tank body, the weld joints of the plurality of first support members to the outer peripheral wall of the spherical tank body are at the same horizontal height.

[0022] In some embodiments, the second support component includes a first connecting segment and a second connecting segment connected in sequence, the first connecting segment being welded to a second surface, and the second connecting segment being welded to both the second surface and the support column.

[0023] In some embodiments, the support column has a first mounting end and a second mounting end, with the first mounting end spaced above the second mounting end along the height direction of the spherical tank body; multiple support columns are provided, with multiple support columns spaced apart along the circumferential direction of the spherical tank body.

[0024] The spherical tank structure also includes:

[0025] The first connector has one end connected to the first mounting end of the first support column and the other end connected to the second mounting end of the second support column.

[0026] The second connector has one end connected to the second mounting end of the first support column and the other end connected to the first mounting end of the second support column.

[0027] The first connector and the second connector are spaced apart;

[0028] Alternatively, the first connector and the second connector are hinged together.

[0029] In some embodiments, a support column has two first mounting ends, which are spaced apart along the height direction intersecting the body of the spherical tank.

[0030] Two second mounting ends are provided on a support column, and the two second mounting ends are spaced apart along the height direction intersecting the body of the spherical tank.

[0031] In some implementations, the pillar includes:

[0032] The outriggers are connected to the second surface and the second support assembly, respectively.

[0033] The first mounting component is sleeved on the outer wall of the outrigger, and the first mounting end is located on the first mounting component;

[0034] The second mounting component is sleeved on the outer wall of the outrigger, and the second mounting end is located on the second mounting component;

[0035] Along the height direction of the spherical tank body, the first mounting component is positioned above the second mounting component at intervals.

[0036] Secondly, this application provides a processing method for spherical tank structures, the processing method comprising the following steps:

[0037] The first surface of the first support component is welded to the outer peripheral wall of the spherical tank body;

[0038] Weld the support column to the second surface of the second support assembly;

[0039] The second support assembly is welded to the second surface and the pillar respectively;

[0040] The reinforcing members are welded to the first support assembly and the column, respectively.

[0041] This spherical tank structure, by incorporating a first support component and ensuring its first surface is in close contact with the outer peripheral wall of the tank body, reduces abrupt geometric changes between the two. The first surface also forms a reinforcing surface on the outer peripheral wall of the tank body. Furthermore, the first support component can form a ring-shaped reinforcing structure on the outer peripheral wall of the tank body, allowing the pressure or stress of the tank body to be distributed over a larger area, thereby reducing stress concentration between the tank body and the first support component. By incorporating a second support component and welding it to both the second surface and the support column, a smooth, rigid transition is achieved between the tank body and the support column, reducing stress peaks caused by sudden changes in cross-section between the tank body and the support column. In addition, compared to the traditional method of directly welding the spherical tank body and the support column using fillet welds, by setting up a first support component and a second support component, the stress originally applied to the support column can be dispersed. Furthermore, the original single high-risk weld between the spherical tank body and the support column can be broken down into welds between the first surface and the spherical tank body, between the first and second support components, between the second surface and the support column, and between the second support component and the support column. This results in multiple low-stress weld segments, reducing the superposition of residual welding stress between the spherical tank body and the support column. This improves the connection strength and stability between the spherical tank body and the support column. Adding reinforcing members further enhances the connection stability between the first support and the support column.

[0042] Therefore, the spherical tank structure provided in the embodiments of this application can solve the problem of poor connection strength at the connection between the spherical shell and the support column, which would lead to a decrease in the safety performance of the spherical tank.

[0055] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0056] In the prior art, the spherical shell and the support are connected by fillet welding.

[0057] As the weight or volume of the fluid inside the spherical shell changes, the pressure inside the shell will also change. In this situation, due to insufficient fatigue strength at the fillet weld between the support and the shell, fatigue failure will occur at the fillet weld, leading to fracture at the connection between the shell and the support. This results in a deterioration in the safety performance of the spherical tank.

[0058] To overcome the shortcomings of existing technologies, by setting a first support component and ensuring its first surface is in contact with the outer peripheral wall of the spherical tank body, the geometric abrupt changes between the first support component and the spherical tank body can be reduced. The first surface can also form a reinforcing surface on the outer peripheral wall of the spherical tank body. Furthermore, the first support component can form a ring-shaped reinforcing structure on the outer peripheral wall of the spherical tank body, allowing the pressure or stress of the spherical tank body to be distributed over a larger area, thereby reducing stress concentration between the spherical tank body and the first support component. By setting a second support component and welding it to both the second surface and the support column, a smooth rigid transition can be formed between the spherical tank body and the support column, reducing stress peaks caused by sudden changes in cross-section between the spherical tank body and the support column. In addition to the formation of the value, compared with the traditional method of directly welding the spherical tank body and the support through fillet welds, by setting up the first support component and the second support component, the stress originally applied to the support can be dispersed. It can also break down the original single high-risk weld between the spherical tank body and the support into welds between the first surface and the spherical tank body, welds between the first support component and the second support component, welds between the second surface and the support, and welds between the second support component and the support. This can be broken down into multiple low-stress welds to reduce the superposition of welding residual stress between the spherical tank body and the support, thereby improving the connection strength between the spherical tank body and the support and enhancing the connection stability between the spherical tank body and the support. Setting up reinforcing members can improve the connection stability between the first support and the support.

[0059] Therefore, the spherical tank structure provided in the embodiments of this application can solve the problem of poor connection strength at the connection between the spherical shell and the support column, which would lead to a decrease in the safety performance of the spherical tank.

[0060] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0061] like Figure 1 and Figure 2 As shown, this application provides a spherical tank structure, including: a spherical tank body 100, a first support component 200, a second support component 300, a pillar 400, and a reinforcing member 500. The first support component 200 has a first surface 201 and a second surface 202 disposed opposite to each other. The first support component 200 is welded around the outside of the spherical tank body 100. The first surface 201 is fitted to the outer peripheral wall of the spherical tank body 100 to form an annular reinforcing structure on the outside of the spherical tank body 100. The second support component 300 is welded to the second surface 202. The pillar 400 is welded to the second support component 300 and to the second surface 202. One end of the reinforcing member 500 is welded to the first support component 200, and the other end of the reinforcing member 500 is connected to the pillar 400.

[0062] The following sections provide a detailed description of the specific structure of the spherical tank and various possible implementation methods.

[0063] It should be noted that the first support component 200 can be a continuous ring-shaped support structure, i.e., a support ring, or an intermittent ring-shaped support structure, i.e., a support structure formed by multiple first support components spaced apart. There are no restrictions here, and it can be selected according to actual usage requirements.

[0064] Furthermore, the support rings can be set to one, two, three, or other values ​​greater than or equal to one; there are no restrictions here, and they can be selected according to actual usage requirements.

[0065] Furthermore, when multiple support rings are provided, the multiple support rings are spaced apart along the outer peripheral wall of the spherical tank body 100.

[0067] In one embodiment, the first surface 201 is circular in shape.

[0068] It is understandable that when the first surface 201 is circular, the first surface 201 and the outer peripheral wall of the spherical tank body 100 can fit more tightly, thereby reducing the generation of geometrical abrupt changes between the first support component 200 and the spherical tank body 100.

[0069] In one embodiment, the first surface 201 is in the shape of a circular strip.

[0070] It is understandable that when the first surface 201 is circular, the first surface 201 and the outer peripheral wall of the spherical tank body 100 can fit more tightly, thereby reducing the generation of geometrical abrupt changes between the first support component 200 and the spherical tank body 100. In addition, it can also distribute the stress between the first support component 200 and the spherical tank body 100 to a larger area, thereby reducing the occurrence of stress between the spherical tank body 100 and the first support component 200.

[0071] It should be noted that the spherical tank body 100 has a storage chamber inside, which can be used to store a medium, such as liquid hydrogen, liquid oxygen, liquefied natural gas or other cryogenic liquefied gases. There are no restrictions on the medium, and it can be selected according to actual usage requirements.

[0072] It should be noted that the support column 400 and the second surface 202 are connected by welding.

[0074] Furthermore, the welds between the reinforcing member 500 and the support column 400, as well as the welds between the reinforcing member 500 and the first support assembly 200, are both double-sided fillet welds.

[0075] It should be noted that the reinforcing component 500 can be a reinforcing rib or a reinforcing plate; there are no restrictions, and it can be selected according to actual usage requirements.

[0078] It should be noted that the double-sided full penetration welding method can be to open a double-sided weld bevel on the first surface 201. There are no restrictions on the form and size of the bevel, as long as it is ensured that the weld between the first support component 200 and the spherical tank body 100 can achieve full penetration.

[0082] It is understood that the above-described embodiments facilitate the rounding of weld seams and reduce stress concentration at the connection between the first surface 201 and the spherical tank body 100.

[0083] It should be noted that the surface of the weld between the first surface 201 and the spherical tank body 100 is subjected to non-destructive testing.

[0084] It is understood that the above-described embodiments can prevent potential failures and accidents between the spherical tank body 100 and the first support component 200, thereby improving the safety of the overall structure.

[0085] It should be noted that non-destructive testing includes one or a combination of magnetic particle testing or penetrant testing of non-ferromagnetic materials. There are no restrictions on this, and the appropriate method can be selected based on actual application requirements.

[0086] It should be noted that magnetic particle testing can be used for routine surface crack screening of the weld between the first surface 201 and the spherical tank body 100.

[0087] Furthermore, magnetic particle testing can be performed by magnetizing the weld, then spreading magnetic powder, and the leakage magnetic field at the defect will attract the magnetic powder to form a magnetic trace.

[0088] It should be noted that non-ferromagnetic material penetrant testing can be used to detect surface opening defects in the weld between the first surface 201 and the spherical tank body 100. Surface opening defects can be cracks or pores.

[0089] Furthermore, penetrant testing of non-ferromagnetic materials can be performed by applying red dye or fluorescent agent to the weld surface. The penetrant penetrates the surface opening defects and forms a visual indication after being adsorbed by the developer.

[0126] Furthermore, one end of the first connector 600 passes through the first through hole of the first mounting member 402 on the first support column 400, and the other end of the first connector 600 passes through the second through hole of the second mounting member 403 on the second support column 400. One end of the second connector 700 passes through the second through hole of the second mounting member 403 on the first support column 400, and the other end of the second connector 700 passes through the first through hole of the first mounting member 402 on the second support column 400.

[0127] It is understood that, through the above implementation method, two adjacent support columns 400 can be connected through the first support column 400, the second support column 400, the first mounting end, and the second mounting end, so as to improve the service life of the spherical tank structure.

[0128] In one embodiment, the lower surface of the first mounting member 402 forms a first mounting end, and the upper surface of the second mounting member 403 forms a second mounting end.

[0129] Furthermore, one end of the first connector 600 is connected to the lower surface of the first mounting member 402 of the first support 400, and the other end of the first connector 600 is connected to the upper surface of the second mounting member 403 of the second support 400. One end of the second connector 700 is connected to the upper surface of the second mounting member 403 of the first support 400, and the other end of the second connector 700 is connected to the lower surface of the first mounting member 402 of the second support 400.

[0130] It is understood that, through the above implementation method, two adjacent support columns 400 can be connected through the first support column 400, the second support column 400, the first mounting end, and the second mounting end, so as to improve the service life of the spherical tank structure.

[0131] It is understandable that there are no restrictions on the specific settings of the first and second installation ends, and they can be selected according to actual usage needs.

[0132] It should be noted that the first mounting component 402 can be a first mounting plate or a first mounting block, and there is no restriction on it. It can be selected according to the actual use requirements.

[0133] It should be noted that the second mounting component 403 can be a second mounting plate or a second mounting block, and there are no restrictions on it. It can be selected according to the actual use requirements.

[0134] It should be noted that the first connecting part 600 can be the first connecting rod or the first connecting rope, and there is no restriction. It can be selected according to the actual use requirements.

[0135] It should be noted that the second connector 700 can be a second connecting rod or a second connecting rope; there are no restrictions, and it can be selected according to actual usage requirements.

[0136] like Figure 3 As shown, an embodiment of this application provides a processing method applied to the spherical tank structure provided in any of the above embodiments. The processing method includes the following steps:

[0137] S01: Weld the first surface 201 of the first support component 200 to the outer peripheral wall of the spherical tank body 100;

[0138] S02: Weld the support column 400 to the second surface 202 of the second support assembly 300;

[0139] S03: Weld the second support assembly 300 to the second surface 202 and the column 400 respectively;

[0140] S04: Weld the reinforcing member 500 to the first support assembly 200 and the column 400 respectively.

[0141] It is understood that, through the above embodiments, the first surface 201 of the first support component 200 can be connected to the outer peripheral wall of the spherical tank body 100, which can reduce the occurrence of geometrical abrupt changes between the first support component 200 and the spherical tank body 100. The first support component 200 can also form a ring-shaped reinforcing structure, thereby dispersing the stress between the first support component 200 and the spherical tank body 100 to a larger area, thus reducing the occurrence of stress concentration between the spherical tank body 100 and the first support component 200. Furthermore, the second support component 300 can be connected to the second surface 202 and the support column 400 respectively, forming a smooth rigid transition between the spherical tank body 100 and the support column 400, reducing... In addition to reducing the stress peak caused by the sudden change in cross-section between the tank body 100 and the support column 400, compared to the traditional method of directly welding the tank body 100 and the support column 400 with fillet welds, by setting the first support component 200 and the second support component 300, the single high-risk weld between the tank body 100 and the support column 400 can be divided into multiple low-stress welds. This reduces the superposition of welding residual stress between the tank body 100 and the support column 400, thereby improving the connection strength between the tank body 100 and the support column 400 and enhancing the connection stability between the tank body 100 and the support column 400. Setting the reinforcing member 500 can improve the connection stability between the first support and the support column 400.

[0142] It should be noted that the terms "one embodiment," "embodiment," "exemplary embodiment," "some embodiments," etc., mentioned in the specification indicate that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, such phrases do not necessarily refer to the same embodiment. Moreover, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments, whether explicitly described or not, is within the knowledge scope of those skilled in the art.

[0143] Generally speaking, terms should be understood at least in part by their use in context. For example, at least in part by context, the term "one or more" as used in the text can be used to describe any feature, structure, or characteristic of the singular meaning, or a combination of features, structures, or characteristics of the plural meaning. Similarly, at least in part by context, terms such as "a" or "the" can also be understood to convey either singular or plural usage.

[0144] It should be readily understood that the terms “on,” “above,” and “on top of” in this application should be interpreted in the broadest possible sense, such that “on” means not only “directly on something” but also “on something” with an intermediate feature or layer therebetween, and that “above” or “on top of” means not only “on something” but also “on something” without an intermediate feature or layer therebetween (i.e., directly on something).

[0145] Furthermore, for ease of explanation, spatially relative terms such as "below," "below," "under," "above," and "above" may be used to describe the relationship of one element or feature relative to other elements or features as shown in the figures. Spatially relative terms are intended to encompass different orientations of the device in use or operation other than those shown in the figures. The device may have other orientations (rotated 90° or in other orientations), and the spatially relative descriptive terms used herein may be interpreted accordingly.

[0146] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
