Correction field superconducting coils are key components of superconducting tokamaks, and the magnetic field configuration and intensity generated by these coils play a crucial role in confining plasma motion.

[0003] In the related technology, in the current superconducting tokamak device, the correction field superconducting coil is located between the longitudinal field and the poloidal field coils, and the remaining space around the correction field superconducting coil is relatively large, resulting in the internal space of the fusion device being not compact enough and the overall device size being larger. In addition, the support of the correction field superconducting coil is mainly completed and borne in the form of support clamps. When the correction field superconducting coil is located outside the poloidal field coil, the remaining space inside the fusion device is relatively compact and the overall device size is smaller.

[0033] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0034] Currently, magnetic confinement fusion is one of the primary approaches to controlled nuclear fusion research, and the superconducting tokamak is a leading device for this research worldwide. The correction field superconducting coil 200 is a key component of the superconducting tokamak. The magnetic field configuration and intensity generated by the correction field superconducting coil 200 play a crucial role in confining plasma operation.

[0035] In current superconducting tokamaks, the correction field superconducting coil 200 is located between the longitudinal field and poloidal field coils, leaving a relatively large space around the correction field superconducting coil 200. This results in a less compact internal space for the fusion device and a larger overall device size. Furthermore, the correction field superconducting coil 200 is primarily supported and supported by a support clamp. When the correction field superconducting coil 200 is located outside the poloidal field coil, the remaining space within the fusion device is relatively compact and the overall device size is relatively small. During operation of the superconducting tokamak, if the support structure 100 is insufficiently rigid, the positional accuracy of the correction field superconducting coil 200 will deviate significantly. This, in turn, will result in insufficient positional accuracy of the magnetic field generated by the correction field superconducting coil 200, making it impossible to fully confine the plasma. This could cause some plasma to escape confinement and directly contact components within the vacuum chamber of the superconducting tokamak, potentially damaging the components. At the same time, when the superconducting tokamak device is in operation, heat conduction and heat radiation inside and outside the superconducting tokamak device are transferred to the correction field superconducting coil 200 to increase its temperature, affecting the working efficiency of the low-temperature correction field superconducting coil 200.

[0036] Reference below Figures 1-4 The support structure 100 of the correction field superconducting coil 200 according to an embodiment of the present application is described.

[0037] According to an embodiment of the present application, the support structure 100 is used to support the correction field superconducting coil 200. The correction field superconducting coil 200 is applied to a superconducting tokamak device, and the superconducting tokamak device has multiple groups of correction field superconducting coils 200 arranged in a circular pattern. The multiple groups of correction field superconducting coils 200 are arranged adjacent to each other in a circular pattern, and the correction field superconducting coil 200 is arranged between the longitudinal field coil and the poloidal field coil of the superconducting tokamak device.

[0038] Reference Figure 1 As shown, the support structure 100 according to an embodiment of the present application includes: a first support assembly 1, a second support assembly 2, a vertical support assembly 3 and a cooling assembly.

[0039] Among them, the first support assembly 1 is arranged on the longitudinal field coil, and the first support assembly 1 is used to support the upper arc segment of the correction field superconducting coil 200, the second support assembly 2 is fixed on the ground support structure 400 of the longitudinal field coil, and the second support assembly 2 is used to support the lower arc segment of the correction field superconducting coil 200, the vertical support assembly 3 is located between the first support assembly 1 and the second support assembly 2 in the vertical direction and is arranged on the poloidal field coil, and the vertical support assembly 3 is used to fix the two vertical extension segments in the two adjacent groups of correction field superconducting coils 200, so as to simultaneously constrain the two vertical extension segments in the horizontal direction, and constrain and fix the adjacent vertical extension segments of the two adjacent groups of correction field superconducting coils 200.

[0040] It should be noted that the correction field superconducting coil 200 is arranged in a ring shape, and when the correction field superconducting coil 200 is applied to a superconducting tokamak device, the correction field superconducting coil 200 is arranged vertically. The correction field superconducting coil 200 has an upper arc segment and a lower arc segment and two vertical extension segments connected between the upper arc segment and the lower arc segment.

[0041] The upper arc segment is connected to and cooperates with the first support assembly 1 to constrain the upper arc segment through the first support assembly 1; the lower arc segment is connected to and cooperates with the second support assembly 2 to constrain the lower arc segment through the second support assembly 2. The arc-shaped opening of the upper arc segment faces the center of the superconducting tokamak device, which is also the inner side of the superconducting tokamak device, and the arc-shaped opening of the lower arc segment also faces the center of the superconducting tokamak device. The two vertically extending sections are respectively connected between the ends of the upper arc segment and the ends of the lower arc segment, forming an arc-shaped curved space surrounded by the correction field superconducting coil 200.

[0042] It can be understood that in a superconducting tokamak device, the vertical extensions of two adjacent groups of correction field superconducting coils 200 are arranged adjacent to each other, so that the two adjacent vertical extensions of the two groups of correction field superconducting coils 200 can be constrained by the same vertical support assembly 3. Therefore, in a superconducting tokamak device, a group of support structures 100 includes only one group of vertical support assemblies 3. When a group of correction field superconducting coils 200 is installed and mated with the support structure 100, one of the two vertical extensions of the group of correction field superconducting coils 200 mates with the vertical support assembly 3 of the corresponding group of support structures 100, and the other of the two vertical extensions mates with the vertical support assembly 3 of the adjacent group of support structures 100. In other words, the number of groups of correction field superconducting coils 200 in the superconducting tokamak device is the same as the number of groups of support structures 100, and each group of support structures 100 is arranged in the same manner in the superconducting tokamak device.

[0043] It should be noted that eight groups of correction field superconducting coils 200 are provided in the superconducting tokamak device. Accordingly, the eight groups of correction field superconducting coils 200 are respectively constrained and fixed by eight groups of support structures 100 .

[0044] Reference Figure 4 As shown, a cooling assembly is also provided on the support structure 100. The cooling assembly can be used to exchange heat with the first support assembly 1 and the second support assembly 2, so as to transfer heat from the support structure 100 by a heat exchange medium (such as liquid helium) flowing through the cooling assembly, thereby achieving temperature reduction regulation at the support structure 100, thereby achieving the overall thermal balance of the superconducting tokamak device.

[0045] The support structure 100 according to the embodiment of the present application effectively constrains and secures the correction field superconducting coil 200. Furthermore, the cooling components arranged on the first support assembly 1 and the second support assembly 2 achieve thermal equilibrium, preventing excessive temperatures at the support structure 100. This effectively improves the positioning accuracy and operating efficiency of the correction field coil within the fusion device. Specifically, the first support assembly 1 is used for mounting and cooperating with the longitudinal field coil, the second support assembly 2 is used for mounting and cooperating with the ground support structure 400 that mounts and secures the longitudinal field coil, and the vertical support assembly 3 is mounted and cooperating with the poloidal field coil. This allows the correction field superconducting coil 200 to be mounted and secured using coil structures arranged around it (e.g., the longitudinal field coil and the poloidal field coil) and the structure that secures the coil (e.g., the ground support structure 400). This reduces the space required for the support structure 100 and helps improve the compactness of the arrangement of the correction field coil, longitudinal field coil, and poloidal field coil.

[0046] It can be understood that the support structure 100 in the present application is simple to operate and occupies less space than the fixing method of the support clamp in the existing technical solution. There is no need to add a new installation structure inside the fusion device (i.e., a structure for arranging the support clamp), which can improve the compactness of the interior of the fusion device and reduce the overall size.

[0047] Combine Figure 3 and Figure 4 As shown, in some embodiments of the present application, the support structure 100 further includes multiple sets of clamps 5, each set of clamps 5 being provided on the first support assembly 1, the second support assembly 2, and the vertical support assembly 3, and being used to clamp and secure the correction field superconducting coil 200. In other words, the clamps 5 are provided on each of the first support assembly 1, the second support assembly 2, and the vertical support assembly 3, so as to achieve clamping, restraining, and securing of the correction field superconducting coil 200 through the clamps 5.

[0048] Reference Figure 3 and Figure 4 As shown, the clamp 5 includes: a first clamping plate 51, a second clamping plate 52, an adjusting bolt 53 and an insulating assembly 54. The first clamping plate 51 and the second clamping plate 52 are arranged relative to each other in the inner and outer directions, so as to clamp the correction field superconducting coil 200 in the inner and outer directions through the first clamping plate 51 and the second clamping plate 52. The adjusting bolt 53 is passed through the first clamping plate 51 and is connected to the second clamping plate 52. The adjusting bolt 53 is used to adjust the clamping distance between the first clamping plate 51 and the second clamping plate 52 to realize the clamping action of the first clamping plate 51 and the second clamping plate 52 on the correction field superconducting coil 200.

[0049] It should be noted that the above-mentioned “inside” refers to the side close to the center position of the superconducting tokamak device, and the above-mentioned “outside” refers to the side relatively far from the center position of the superconducting tokamak device.

[0050] Furthermore, the insulating assembly 54 is arranged between the first clamping plate 51 and the second clamping plate 52, and the insulating assembly 54 is used to insulate and protect the correction field superconducting coil 200, so as to separate the clamp 5 from the correction field coil through the insulating assembly 54, thereby reducing the influence of the magnetic field on the clamp 5 (the first clamping plate 51, the second clamping plate 52 and the adjusting bolt 53).

[0051] The insulation assembly 54 can be constructed as a multi-layer structure, with at least one layer of the multi-layer structure having an insulating function. The insulation assembly 54 can also have excellent thermal insulation properties, thereby blocking heat transfer from the fixture 5, thereby reducing the impact of heat on the fixture 5 and the supporting components (i.e., the first support assembly 1, the second support assembly 2, and the vertical support assembly 3) on which the fixture 5 is mounted, thereby ensuring the assembly accuracy of the correction field superconducting coil 200.

[0052] It is understood that the first support assembly 1, the second support assembly 2, and the vertical support assembly 3 can all be made of metal components. Taking the first support assembly 1 as an example, when heat is transferred to the first support assembly 1, the volume of the first support assembly 1 will change due to the temperature, thereby affecting the assembly accuracy of the calibration field.

[0053] In some preferred embodiments of the present application, the adjusting bolt 53 is configured as a hexagon socket bolt.

[0054] In a further embodiment of the present application, during the cooperation between the first clamping plate 51, the second clamping plate 52, and the adjusting bolt 53, a through-hole structure for the adjusting bolt 53 to pass through may be formed on the first clamping plate 51, and a threaded hole structure threadedly engaged with the adjusting bolt 53 may be formed on the second clamping plate 52. Thus, by threading the adjusting bolt 53 in engagement with the threaded hole, the positions of the first clamping plate 51 and the second clamping plate 52 in the axial direction of the adjusting bolt 53 can be adjusted. The threaded hole structure may be provided on the second clamping plate 52, or may be formed on a nut that is fixedly engaged with the second clamping plate 52.

[0055] Combine Figure 3 and Figure 4 As shown, the insulating assembly 54 includes a plurality of insulating plates 541, which define a space for the correction field superconducting coil 200 to pass through, and two insulating plates 541 facing each other in the inner and outer directions are pressed against each other to tightly fit the insulating plates 541 and the correction field superconducting coil 200, thereby improving the restraining and clamping effect on the correction field superconducting coil 200.

[0056] In a specific embodiment of the present application, each group of insulating components 54 includes four insulating plates 541, and the four insulating plates 541 are arranged opposite to each other in pairs, and slots arranged opposite to each other in the inner and outer directions are provided on the first clamping plate 51 and the second clamping plate 52. The two insulating plates 541 opposite to each other in the inner and outer directions are respectively arranged in the two slots, and the other two insulating plates 541 are respectively arranged on both sides of the two insulating plates 541 opposite to each other. The inner wall surface of the insulating plate 541 located on the inner side of the two insulating plates 541 arranged inside and outside is opposite to the second clamping plate 52 and is at least flush with the inner ends of the other two insulating plates 541. The outer wall surface of the insulating plate 541 located on the outer side of the two insulating plates 541 arranged inside and outside is opposite to the first clamping plate 51 and is at least flush with the outer ends of the other two insulating plates 541, thereby ensuring the cooperation effect between the two insulating plates 541 arranged inside and outside and the first clamping plate 51 and the second clamping plate 52.

[0057] Combine Figure 1 and Figure 2 As shown, in some embodiments of the present application, the first support assembly 1 includes: a first support beam 11 and a support arm 12, the first support beam 11 is arranged on the mounting opening 301 of the longitudinal field coil to bear the weight of the first support beam 11 through the longitudinal field coil, the inner end of the support arm 12 is connected to the first support beam 11, and the support arm 12 extends outward in a radial direction, and the outer end of the support arm 12 is used to install the clamp 5 to clamp and fix the upper arc segment.

[0058] It should be noted that a longitudinal field coil is provided in the superconducting tokamak device, and a mounting structure 300 may be provided on the longitudinal field coil. The mounting structure 300 may be integrated into the coil box of the longitudinal field coil, or may be a separate component fixedly connected to the coil box. Figure 5 As shown, the mounting structure 300 is provided with a mounting opening 301, which is used for the first support beam 11 to extend into, so as to plug and match the first support beam 11 with the mounting structure 300, thereby fixing the first support assembly 1 and the longitudinal field coil, and sharing the weight of the correction field superconducting coil 200 through the longitudinal field coil.

[0059] It is understandable that the first support beam 11 is connected and matched with the support arm 12 to form a cantilever structure protruding outward, so that the clamp 5 can be fixed at a position suitable for clamping and matching with the correction field superconducting coil 200 through the support arm 12.

[0060] It should be noted that the mounting opening 301 of the longitudinal field coil refers to a groove structure defined by the longitudinal field coil. The mounting opening 301 is open to one side, and the first support beam 11 can extend from the open side of the mounting opening 301 into the groove structure and be supported on the longitudinal field coil, thereby enabling the installation of the first support beam 11 through the longitudinal field coil. The shape of the mounting opening 301 formed in the longitudinal field coil matches the cross-sectional shape of the first support beam 11 in the extension direction, thereby improving the installation effect of the first support beam 11 and the longitudinal field coil. After the support structure 100 is connected to the correction field superconducting coil 200, the weight of the correction field superconducting coil 200 can be shared by the longitudinal field coil.

[0061] Combine Figure 1 and Figure 2 As shown, in a further embodiment of the present application, the first support beam 11 includes a first support segment 111 and a second support segment 112, and the first support segment 111 and the second support segment 112 are connected to form a V-shaped beam with an opening open to the inside, and the first support segment 111 and the second support segment 112 are respectively connected to a group of support arms 12 and clamps 5.

[0062] Specifically, a support arm 12 extending in a radial direction is provided on the first support segment 111, and a clamp 5 is provided at the outer end of the support arm 12; a support arm 12 extending in a radial direction is provided on the second support segment 112, and a clamp 5 is provided at the outer end of the support arm 12. The support arms 12 on the first support segment 111 and the support arms 12 on the second support segment 112 extend in different directions, and the two support arms 12 on the first support beam 11 are arranged in a gradually expanding shape from the inside to the outside. This allows the two sets of clamps 5 provided on the first support beam 11 to correspond to different positions of the upper arc segment in the extension direction, thereby improving the support effect of the first support assembly 1 on the upper arc segment.

[0063] Reference Figure 1 As shown, in some embodiments of the present application, a group of first support assemblies 1 includes two groups of first support beams 11 arranged at intervals, and the first support segments 111 in one group of first support beams 11 and the second support segments 112 in another group of first support beams 11 arranged adjacent thereto are arranged colinearly, and the two first support beams 11 can be respectively installed and supported at the installation opening 301.

[0064] Thus, the first support assembly 1 can create space to avoid the longitudinal field coil by spacing the two sets of first support beams 11 apart, reducing the difficulty of assembling the first support beams 11 and the longitudinal field coil. Furthermore, four cantilever structures (i.e., a set of connected and mating support arms 12 and fixtures 5) can be formed in the first support assembly 1, and the upper arc segment can be clamped and constrained by these four cantilevers.

[0065] like Figure 1 As shown, in some embodiments of the present application, a reinforcing rib 13 is provided on the support arm 12. The extending direction of the reinforcing rib 13 is the same as the extending direction of the support arm 12, and at least a portion of the reinforcing rib 13 extends from the support arm 12 to the first support beam 11, so as to improve the connection strength between the first support beam 11 and the support arm 12 through the reinforcing rib 13. The reinforcing rib 13 is provided on the upper surface of the first support beam 11 and the support arm 12.

[0066] Combine Figure 1 and Figure 2 As shown, in some embodiments of the present application, a vertically arranged hanging ear 121 is provided at the end of the support arm 12 , and the hanging ear 121 is formed with a mounting surface, and the mounting surface is used to install the clamp 5 .

[0067] It can be understood that the lug 121 can increase the contact and fitting area between the support arm 12 and the clamp 5, thereby improving the assembly reliability of the support arm 12 and the clamp 5, so that the force at the clamp 5 can be reliably transmitted to the support arm 12, which helps to improve the clamping and restraining effect of the first support component 1 on the upper arc segment.

[0068] Reference Figure 4 In the clamp 5, a locating pin 521 is provided on the side of the second clamping plate 52 facing away from the first clamping plate 51. This locating pin 521 is used to connect with the mounting structure on the support assembly. Taking the installation and coordination of the clamp 5 and the mounting lug 121 as an example, when the clamp 5 is provided with the locating pin 521 on the second clamping plate 52, a pin hole structure (not shown) is formed on the mounting surface of the mounting lug 121. This pin hole structure is used to connect with the locating pin 521, thereby facilitating the installation of the mounting lug 121 and the clamp 5. This simple and reliable installation method is achieved.

[0069] like Figure 1 As shown, in some embodiments of the present application, the second support assembly 2 includes: a second support beam 21 and a support seat 22, the second support beam 21 is arranged on the ground support structure 400, the support seat 22 is connected to the radial outside of the second support beam 21, and the support seat 22 is used to install the clamp 5 to clamp and fix the lower arc segment through the clamp 5.

[0070] It will be appreciated that in a superconducting tokamak, the longitudinal field coil is secured to the ground via a ground support structure 400. The second support beam 21 in this application can be mounted and engaged with the ground support structure 400 to secure the second support beam 21 within the superconducting tokamak. Furthermore, the support base 22 is disposed outside the second support beam 21 and is used to mount the clamp 5. The clamp 5 is then positioned on the second support assembly 2, thereby securing the lower arc-shaped section of the correction field superconducting coil 200 to the second support assembly 2.

[0071] Among them, combined Figure 1 and Figure 5 As shown, the ground support structure 400 can be constructed as a hollow structure, and the installation sections 212 in two adjacently arranged second support beams 21 can be plugged into and matched with the hollow structure to achieve the installation and fixation of the second support beams 21 and the ground support structure 400.

[0072] like Figure 1 As shown, in a further embodiment of the present application, a group of second support assemblies 2 has two groups of second support beams 21, and the second support beam 21 includes: a U-shaped beam section 211 and two mounting sections 212, the opening of the U-shaped beam section 211 faces inward, and two support seats 22 are provided on one U-shaped beam section 211, and the two support seats 22 are arranged on the U-shaped beam section 211 at intervals along the circumferential direction, and each support seat 22 is installed with a group of clamps 5, so that multiple groups of clamps 5 are provided on one second support beam 21 at the same time, so as to increase the number of clamping points of the second support assembly 2 on the lower arc section, thereby improving the clamping and restraining effect of the second support assembly 2 on the lower arc section.

[0073] Furthermore, the two mounting sections 212 are respectively connected to the two open ends of the U-shaped beam section 211, and the two mounting sections 212 extend away from the opening side, and the mounting sections 212 are used to connect and cooperate with the ground support structure 400 to achieve the connection and fixation of the second support beam 21 and the ground support structure 400.

[0074] Reference Figure 1 As shown, an avoidance portion 23 is formed between two groups of adjacently arranged second support beams 21 , and the avoidance portion 23 can avoid the longitudinal field coil to prevent the support structure 100 from interfering with the longitudinal field coil.

[0075] like Figure 1 As shown, in some embodiments of the present application, the vertical support assembly 3 includes an upper support segment 31, a lower support segment 32, and a middle support segment 33. The upper support segment 31 and the lower support segment 32 are spaced apart in the vertical direction, and the upper support segment 31 is used to support and cooperate with the third coil of the poloidal field coil, while the lower support segment 32 is used to support and cooperate with the fourth coil of the poloidal field coil. Thus, the upper support segment 31 and the lower support segment 32 cooperate with the poloidal field to achieve the installation and fixation of the vertical support assembly 3 in the superconducting tokamak device. The middle support segment 33 is connected between the upper support segment 31 and the lower support segment 32 and is used to install the clamp 5. The clamp 5 installed on the middle support segment 33 forms a clamping space that extends vertically, allowing the vertical extension section to pass through the clamp 5 in the vertical direction.

[0076] Therefore, the vertical support assembly 3 is fixed by the third coil and the fourth coil in the poloidal field inside the correction field superconducting coil 200, without adding a connection structure in the superconducting tokamak device, which can improve the compactness of the arrangement of the poloidal field coil and the correction field superconducting coil 200 and save the volume of the superconducting tokamak device.

[0077] In some embodiments of the present application, the first cooling portion 4 is constructed as a first cooling pipe, which is connected to the first support beam 11 of the first support assembly 1, and the first cooling pipe is formed with a first liquid inlet 41 and a first liquid return port 42. The first liquid inlet 41 and the first liquid return port 42 are located on the radial inner side of the first support beam 11, so that the first liquid inlet 41 and the first liquid return port 42 are arranged in an area suitable for avoiding the correction field superconducting coil 200, which facilitates the routing of the cooling pipeline in the superconducting tokamak device.

[0078] In some embodiments of the present application, the second cooling portion is constructed as a second cooling pipe, which is connected to the second support beam 21 of the second support assembly 2, and the second cooling pipe is formed with a second liquid inlet and a second liquid return port, and the second liquid inlet and the second liquid return port are located on the radial inner side of the second support beam 21, so that the second liquid inlet and the second liquid return port are arranged in an area suitable for avoiding the correction field superconducting coil 200, which facilitates the routing of the cooling pipeline in the superconducting tokamak device.

[0079] Reference Figure 2 As shown, a first cooling tube is provided on the first support beam 11, and the extension of the first cooling tube matches the shape of the first support beam 11, so that the heat exchange effect of the cooling component on the first support beam 11 can be improved by increasing the contact area between the first cooling tube and the first support beam 11, thereby avoiding that the support structure 100 is affected by the clamping accuracy of the correction field superconducting coil 200 due to excessive temperature.

[0080] According to an embodiment of the present application, the superconducting tokamak device includes: multiple groups of support structures 100, the support structure 100 is the above-mentioned support structure 100 for supporting the confinement correction field superconducting coil 200, and the multiple groups of support structures 100 are arranged in a circular shape.

[0081] Furthermore, the superconducting tokamak device is also provided with a protective component, which is arranged on the circumferential outside of the longitudinal field coil, and the protective component is located between the first support component 1 and the longitudinal field coil to insulate and protect the first support component 1 to prevent eddy currents.

[0082] It should be noted that the advantages of the superconducting tokamak device compared to the existing technology are the same as those of the above-mentioned support structure 100, which will not be repeated here.
