[0003] In related technologies, in the current superconducting tokamak device, the position of the correction field superconducting coil is between the toroidal field and poloidal field coils, and there is a large remaining space around the correction field superconducting coil, resulting in an insufficiently compact internal space of the fusion device and a relatively large overall device size. Moreover, the support of the correction field superconducting coil is mainly completed and borne in the form of support clamps. When the position of the correction field superconducting coil is outside the poloidal field coil, the remaining internal space of the fusion device is relatively compact and the overall device size is smaller.

[0022] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation to the present application.

[0023] Currently, magnetic confinement fusion is one of the main ways to conduct controlled nuclear fusion research, and the superconducting tokamak device is one of the main devices for magnetic confinement fusion research in the world. Among them, the correction field superconducting coil 200 is one of the key components of the superconducting tokamak device. The magnetic field configuration and magnetic field intensity generated by the correction field superconducting coil 200 play an important role in constraining the operation of the plasma.

[0024] In the current superconducting tokamak device, the position of the correction field superconducting coil 200 is located between the toroidal field and poloidal field coils. The remaining space around the correction field superconducting coil 200 is relatively large, resulting in an insufficiently compact internal space of the fusion device and a relatively large overall device size. Moreover, the support of the correction field superconducting coil 200 is mainly completed and borne in the form of support clamps. When the position of the correction field superconducting coil 200 is outside the poloidal field coil, the remaining internal space of the fusion device is relatively compact and the overall device size is smaller. When the superconducting tokamak device is operating, if the stiffness of the support structure 100 is insufficient, it will lead to a large deviation in the position accuracy of the correction field superconducting coil 200, and then the magnetic field configuration accuracy generated by the correction field superconducting coil 200 is insufficient to constrain all the plasma, resulting in some plasma escaping the constraint and directly contacting the internal components of the vacuum chamber in the superconducting tokamak device, causing damage to the vacuum chamber components. At the same time, when the superconducting tokamak device is operating, heat conduction and heat radiation inside and outside the superconducting tokamak device will be transferred to the correction field superconducting coil 200, causing its temperature to rise and affecting the working efficiency of the cryogenic correction field superconducting coil 200.

[0025] Below refer to Figures 1 - 4Describe the support structure 100 of the correction field superconducting coil 200 according to an embodiment of the present application.

[0026] 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 there are multiple groups of correction field superconducting coils 200 arranged in a circumferential pattern in the superconducting tokamak device. The multiple groups of correction field superconducting coils 200 are arranged adjacent to each other in a circumferential order, and the correction field superconducting coil 200 is arranged between the toroidal field coil and the poloidal field coil of the superconducting tokamak device.

[0027] Refer to 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.

[0028] Among them, the first support assembly 1 is arranged on the toroidal field coil, and the first support assembly 1 is used to support the upper arc section of the correction field superconducting coil 200. The second support assembly 2 is fixed on the ground support structure 400 of the toroidal field coil, and the second support assembly 2 is used to support the lower arc section 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 two vertical extension sections of two adjacent correction field superconducting coils 200, so as to simultaneously constrain the two vertical extension sections in the horizontal direction and constrain and fix the vertically adjacent extension sections of the two adjacent correction field superconducting coils 200 arranged adjacent to each other.

[0029] 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 section, a lower arc section, and two vertical extension sections connecting between the upper arc section and the lower arc section.

[0030] Among them, the upper arc section is connected and cooperated with the first support assembly 1 to constrain the upper arc section through the first support assembly 1; the lower arc section is connected and cooperated with the second support assembly 2 to constrain the lower arc section through the second support assembly 2. At the same time, the arc opening of the upper arc section faces the center side of the superconducting tokamak device, which is also the inner side of the superconducting tokamak device, and the arc opening of the lower arc section also faces the center side of the superconducting tokamak device. The two vertical extension sections are respectively connected between the two ends of the upper arc section and the two ends of the lower arc section to form an arc-shaped extended curved surface space through the correction field superconducting coil 200.

[0031] It can be understood that in a superconducting tokamak device, the vertical extension sections in two adjacent sets of correction field superconducting coils 200 are arranged adjacent to each other, so that two adjacent vertical extension sections in two sets of correction field superconducting coils 200 can be constrained by the same vertical support assembly 3. Thus, in the superconducting tokamak device, only one set of vertical support assemblies 3 is included in one set of support structures 100. When one set of correction field superconducting coils 200 is installed and matched with the support structure 100, one of the two vertical extension sections in this set of correction field superconducting coils 200 is matched with the vertical support assembly 3 in one set of support structures 100 arranged corresponding to it, and the other of the two vertical extension sections is matched with the vertical support assembly 3 in one set of support structures 100 arranged adjacent to it. That is to say, the number of sets of correction field superconducting coils 200 in the superconducting tokamak device is the same as the number of sets of support structures 100, and the arrangement mode of each set of support structures 100 in the superconducting tokamak device is the same.

[0032] It should be noted that there are eight sets of correction field superconducting coils 200 provided in the superconducting tokamak device. Correspondingly, the eight sets of correction field superconducting coils 200 are respectively constrained and fixed by eight sets of support structures 100.

[0033] Refer to Figure 4 As shown, a cooling assembly is further provided on the support structure 100. The cooling assembly can be used for heat exchange with the first support assembly 1 and the second support assembly 2, so as to transfer the heat at the support structure 100 through a heat exchange medium (such as liquid helium) flowing through the cooling assembly, realize the temperature reduction adjustment at the support structure 100, and thus achieve the overall thermal balance of the superconducting tokamak device.

[0034] According to the support structure 100 of the embodiment of the present application, it can play a good role in constraining and fixing the correction field superconducting coils 200, and can realize thermal balance through the cooling assembly arranged on the first support assembly 1 and the second support assembly 2, avoiding the over-high temperature at the support structure 100, so as to effectively improve the position accuracy and working efficiency of the correction field coils inside the fusion device. Among them, the first support assembly 1 is used for installation and cooperation with the toroidal field coils, the second support assembly 2 is used for installation and cooperation with the ground support structure 400 for installing and fixing the toroidal field coils, and the vertical support assembly 3 is used for installation and cooperation with the poloidal field coils. Thus, it can be installed and fixed by using the coil structures (such as toroidal field coils, poloidal field coils) arranged around the correction field superconducting coils 200 and the structures for fixing the coils (such as the above-mentioned ground support structure 400), which can save the layout space required by the support structure 100 and help improve the layout compactness of the correction field coils, toroidal field coils and poloidal field coils.

[0035] It can be understood that the support structure 100 in the present application is simpler in operation and occupies less space compared to the fixing method of the support clamp in the prior art solution. There is no need to newly install a structure (i.e., the structure for arranging the support clamp) inside the fusion device, which can improve the compactness inside the fusion device and reduce the overall size.

[0036] Combined Figure 3 with Figure 4 As shown, in some embodiments of the present application, the support structure 100 further includes multiple groups of clamps 5. Each group of clamps 5 is respectively arranged on the first support assembly 1, the second support assembly 2, and the vertical support assembly 3, and is used for clamping and fixing the correction field superconducting coil 200. That is to say, clamps 5 are provided on the first support assembly 1, the second support assembly 2, and the vertical support assembly 3, respectively, so as to realize the clamping and restraint fixation of the correction field superconducting coil 200 through the clamps 5.

[0037] Referring to 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 component 54. The first clamping plate 51 and the second clamping plate 52 are arranged opposite 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 passes through the first clamping plate 51 and is connected to the second clamping plate 52, and the adjusting bolt 53 is used to adjust the clamping distance between the first clamping plate 51 and the second clamping plate 52, so as to realize the clamping action of the first clamping plate 51 and the second clamping plate 52 on the correction field superconducting coil 200.

[0038] It should be noted that the above-mentioned "inner" refers to the side close to the center position in the superconducting tokamak device, and the above-mentioned "outer" refers to the side relatively far from the center position in the superconducting tokamak device.

[0039] Furthermore, the insulating component 54 is arranged between the first clamping plate 51 and the second clamping plate 52, and the insulating component 54 is used for insulating protection at the correction field superconducting coil 200, so as to separate the clamp 5 from the correction field coil through the insulating component 54 and reduce 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).

[0040] Among them, the insulating component 54 can be constructed as a multi-layer structure, and at least one layer structure in the multi-layer structure has an insulating function. The insulating component 54 can also have good heat insulation, so as to block the heat transfer at the clamp 5, so as to reduce the influence of heat on the clamp 5 and the support assembly (i.e., the above-mentioned first support assembly 1, the second support assembly 2, and the vertical support assembly 3) on which the clamp 5 is installed, and ensure the assembly accuracy of the correction field superconducting coil 200.

[0041] It can be understood that the first support component 1, the second support component 2, and the vertical support component 3 can all be composed of metal components. Taking the first support component 1 as an example, when heat is transferred to the first support component 1, the volume of the first support component 1 will change under the influence of temperature, thereby affecting the assembly accuracy of the correction field.

[0042] In some alternative embodiments of the present application, the adjusting bolt 53 is configured as an internal hexagonal bolt.

[0043] In a further embodiment of the present application, during the cooperation process of 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 can be formed on the first clamping plate 51, and a threaded hole structure that is threadedly engaged with the adjusting bolt 53 is formed on the second clamping plate 52. Thus, by threadedly engaging the adjusting bolt 53 with the threaded hole, the position adjustment of the first clamping plate 51 and the second clamping plate 52 in the axial direction of the adjusting bolt 53 can be realized. Among them, the threaded hole structure can be opened on the second clamping plate 52, and the threaded hole structure can also be formed on the nut, and the nut is fixedly engaged with the second clamping plate 52.

[0044] Combined Figure 3 and Figure 4 As shown, the insulating component 54 includes a plurality of insulating plates 541. The plurality of insulating plates 541 surround and define a space for the correction field superconducting coil 200 to pass through, and two insulating plates that are opposite in the inner and outer directions are press-fitted together to closely fit the insulating plates 541 with the correction field superconducting coil 200, thereby enhancing the constraint clamping effect on the correction field superconducting coil 200.

[0045] 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 in pairs opposite to each other. Grooves that are opposite in the inner and outer directions are provided on the first clamping plate 51 and the second clamping plate 52. Two insulating plates that are opposite in the inner and outer directions are respectively arranged in the two grooves, and the other two insulating plates are respectively arranged on both sides of the two insulating plates that are opposite in the inner and outer directions. The inner wall surface of the insulating plate 541 located inside among the two insulating plates arranged in the inner and outer directions is opposite to the second clamping plate 52 and is at least flush with the inner ends of the other two insulating plates. The outer wall surface of the insulating plate 541 located outside among the two insulating plates arranged in the inner and outer directions is opposite to the first clamping plate 51 and is at least flush with the outer ends of the other two insulating plates. Thereby, the cooperation effect between the two insulating plates arranged in the inner and outer directions and the first clamping plate 51 and the second clamping plate 52 can be ensured.

[0046] Combined Figure 1 and Figure 2As shown, in some embodiments of the present application, the first support assembly 1 includes: a first support beam 11 and support arms 12. The first support beam 11 is arranged on the installation opening 301 of the toroidal field coil to bear the weight of the first support beam 11 through the toroidal field coil. The inner end of the support arm 12 is connected to the first support beam 11, and the support arm 12 extends radially outward. The outer end of the support arm 12 is used to install a fixture 5 to clamp and fix the upper arc segment.

[0047] It should be noted that a toroidal field coil is provided in the superconducting tokamak device, and an installation structure 300 can be provided on the toroidal field coil. The installation structure 300 can be integrated on the coil case of the toroidal field coil or can be fixedly connected to the coil case as a separate component. Refer to Figure 5 As shown, an installation opening 301 is provided on the installation structure 300. The installation opening 301 is used for the first support beam 11 to extend into, so as to plug and cooperate the first support beam 11 with the installation structure 300, thereby fixing the first support assembly 1 to the toroidal field coil and sharing the weight of the correction field superconducting coil 200 through the toroidal field coil.

[0048] It can be understood that by connecting and cooperating the first support beam 11 and the support arms 12, a cantilever structure protruding outward is formed, so as to fix the fixture 5 at a position suitable for clamping and cooperating with the correction field superconducting coil 200 through the support arms 12.

[0049] It should be noted that the installation opening 301 of the toroidal field coil refers to a groove structure defined by the toroidal field coil. The installation opening 301 is open on one side. The first support beam 11 can extend into the groove structure from the open side of the installation opening 301 and be supported on the toroidal field coil to realize the installation of the first support beam 11 through the toroidal field coil. Among them, the shape of the installation opening 301 formed on the toroidal field coil matches the cross-sectional shape of the first support beam 11 in the extending direction to improve the installation effect of the first support beam 11 and the toroidal field coil, and after the support structure 100 is connected and cooperated with the correction field superconducting coil 200, the weight of the correction field superconducting coil 200 can be shared through the toroidal field coil.

[0050] Combined with Figure 1 and Figure 2 As shown, in a further embodiment of the present application, the first support beam 11 includes a first support section 111 and a second support section 112, and the first support section 111 and the second support section 112 are connected to form a V-shaped beam with an opening facing inward, and a group of support arms 12 and fixtures 5 are respectively connected to the first support section 111 and the second support section 112.

[0051] Specifically, support arms 12 extending in the radial direction are provided on the first support section 111, and a clamp 5 is provided at the outer end of the support arm 12; support arms 12 extending in the radial direction are provided on the second support section 112, and a clamp 5 is provided at the outer end of the support arm 12. Among them, the extending directions of the support arms 12 on the first support section 111 and the support arms 12 on the second support section 112 are different, 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, so that the two sets of clamps 5 provided on the first support beam 11 can correspond to different positions of the upper arc section in the extending direction, thereby improving the support effect of the first support assembly 1 on the upper arc section.

[0052] Referring to Figure 1 As shown, in some embodiments of the present application, a set of first support assemblies 1 includes two sets of first support beams 11 arranged at intervals, and the first support section 111 in one set of first support beams 11 and the second support section 112 in another set of first support beams 11 arranged adjacent thereto are collinearly arranged, and the two first support beams 11 can be respectively installed and supported at the installation opening 301.

[0053] Thus, the first support assembly 1 can form a space for avoiding the longitudinal field coil by arranging the two sets of first support beams 11 at intervals, and can reduce the assembly difficulty between the first support beam 11 and the longitudinal field coil. At the same time, four cantilever structures (i.e., a set of connected support arms 12 and clamps 5) can be formed in the first support assembly 1, and the upper arc section can be clamped and constrained by the four cantilevers.

[0054] As Figure 1 shown, in some embodiments of the present application, reinforcing ribs 13 are provided on the support arm 12, the extending direction of the reinforcing ribs 13 is the same as the extending direction of the support arm 12, and at least part of the reinforcing ribs 13 extends from the support arm 12 to the first support beam 11 to improve the connection strength between the first support beam 11 and the support arm 12 through the reinforcing ribs 13. Among them, the reinforcing ribs 13 are provided on the upper surfaces of the first support beam 11 and the support arm 12.

[0055] Combined with Figure 1 and Figure 2 shown, in some embodiments of the present application, a vertically arranged lug 121 is provided at the end of the support arm 12, the lug 121 forms an installation surface, and the installation surface is used for installing the clamp 5.

[0056] It can be understood that the lug 121 can increase the contact and cooperation area between the support arm 12 and the clamp 5, thereby improving the assembly reliability between the support arm 12 and the clamp 5, enabling the force at the clamp 5 to be reliably transmitted to the support arm 12, and helping to improve the clamping and constraining effect of the first support assembly 1 on the upper arc section.

[0057] Referring toFigure 4 , in the fixture 5, a positioning pin 521 is provided on the surface of the second clamping plate 52 facing away from the first clamping plate 51. The positioning pin 521 is used for connecting and cooperating with the mounting structure on the support assembly. Taking the installation and cooperation of the fixture 5 and the lug 121 as an example, when the fixture 5 is provided with the positioning pin 521 on the second clamping plate 52, a pin hole structure (not shown in the figure) is formed on the mounting surface of the lug 121. The pin hole structure is used for connecting and cooperating with the positioning pin 521 to realize the installation of the lug 121 and the fixture 5. The installation method is simple and highly reliable.

[0058] As Figure 1 shown, in some embodiments of the present application, the second support assembly 2 includes: a second support beam 21 and a support base 22. The second support beam 21 is provided on the ground support structure 400, and the support base 22 is connected to the radial outside of the second support beam 21. And the support base 22 is used for installing the fixture 5 to clamp and fix the lower arc section through the fixture 5.

[0059] It can be understood that in the superconducting tokamak device, the toroidal field coils are fixed on the ground through the ground support structure 400. The second support beam 21 in the present application can be installed and cooperated through the ground support structure 400 to realize the installation and fixation of the second support beam 21 in the superconducting tokamak device. At the same time, the support base 22 is arranged on the outside of the second support beam 21 and is used for installing the fixture 5 to arrange the fixture 5 on the second support assembly 2, so as to realize the clamping and restraint of the lower arc section of the correction field superconducting coil 200 by the second support assembly 2.

[0060] Among them, as combined with Figure 1 and Figure 5 shown, the ground support structure 400 can be constructed as a hollow structure, and the installation section 212 in two adjacent second support beams 21 can be inserted and cooperated with the hollow structure to realize the installation and fixation of the second support beam 21 and the ground support structure 400.

[0061] As Figure 1 shown, in a further embodiment of the present application, a set of second support assemblies 2 has two sets of second support beams 21, and the second support beam 21 includes: a U-shaped beam section 211 and two installation sections 212. The opening of the U-shaped beam section 211 faces inward, and two support bases 22 are provided on one U-shaped beam section 211. The two support bases 22 are arranged at intervals in the circumferential direction on the U-shaped beam section 211. Each support base 22 installs a set of fixtures 5, so that multiple sets of fixtures 5 are arranged 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, and further improve the clamping and restraint effect of the second support assembly 2 on the lower arc section.

[0062] Furthermore, the two installation sections 212 are respectively connected to the two open ends of the U-shaped beam section 211, and the two installation sections 212 extend away from the opening side. Moreover, the installation section 212 is used for connecting and cooperating with the ground support structure 400 to realize the connection and fixation of the second support beam 21 and the ground support structure 400.

[0063] Referring to Figure 1 As shown, an avoidance portion 23 is formed between two adjacent second support beams 21 arranged in groups. The avoidance portion 23 can avoid the longitudinal field coil to prevent the support structure 100 from interfering with the longitudinal field coil.

[0064] As Figure 1 As shown, in some embodiments of the present application, the vertical support assembly 3 includes: an upper support section 31, a lower support section 32, and a middle support section 33. Among them, the upper support section 31 and the lower support section 32 are arranged at intervals in the vertical direction. The upper support section 31 is used for supporting and cooperating with the No. 3 coil in the poloidal field coil, and the lower support section 32 is used for supporting and cooperating with the No. 4 coil in the poloidal field coil. Thus, the vertical support assembly 3 is installed and fixed in the superconducting tokamak device through the cooperation of the upper support section 31 and the lower support section 32 with the poloidal field. Among them, the middle support section 33 is connected between the upper support section 31 and the lower support section 32, and the middle support section 33 is used for installing the fixture 5. The fixture 5 installed on the middle support section 33 forms a clamping space penetrating in the vertical direction, so that the vertical extension section can pass through the fixture 5 in the vertical direction.

[0065] Thus, the vertical support assembly 3 is fixed by the No. 3 coil and the No. 4 coil in the poloidal field located inside the correction field superconducting coil 200, without adding a connection structure in the superconducting tokamak device, which can improve the layout compactness of the poloidal field coil and the correction field superconducting coil 200 and save the volume of the superconducting tokamak device.

[0066] In some embodiments of the present application, the first cooling portion 4 is configured as a first cooling pipe. The first cooling pipe is connected to the first support beam 11 of the first support assembly 1. Moreover, 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 radially inside the first support beam 11, so as to arrange the first liquid inlet 41 and the first liquid return port 42 in an area suitable for avoiding the correction field superconducting coil 200, which is convenient for the routing of the cooling pipeline in the superconducting tokamak device.

[0067] In some embodiments of the present application, the second cooling part is configured as a second cooling pipe. The second cooling pipe 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. The second liquid inlet and the second liquid return port are located radially inside the second support beam 21, so as to arrange the second liquid inlet and the second liquid return port in an area suitable for avoiding the correction field superconducting coil 200, which is convenient for the routing of the cooling pipeline in the superconducting tokamak device.

[0068] Referring to Figure 2 As shown, a first cooling pipe is provided on the first support beam 11. The extension of the first cooling pipe matches the shape of the first support beam 11, so that the heat exchange effect of the cooling assembly on the first support beam 11 can be improved by increasing the contact area between the first cooling pipe and the first support beam 11, thereby preventing the support structure 100 from affecting the clamping accuracy of the correction field superconducting coil 200 due to excessive temperature.

[0069] The superconducting tokamak device according to the embodiment of the present application includes: multiple groups of support structures 100. The support structure 100 is the above-mentioned support structure 100 for supporting and constraining the correction field superconducting coil 200, and multiple groups of support structures 100 are arranged in a circumferential arrangement.

[0070] Furthermore, the superconducting tokamak device is further provided with a protection assembly. The protection assembly is arranged on the circumferential outer side of the toroidal field coil, and the protection assembly is located between the first support assembly 1 and the toroidal field coil to insulate and protect the first support assembly 1 to prevent eddy currents.
