[0072] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein 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 accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0073] The following is for reference. Figures 1-8 The present invention describes an installation and positioning device 10 for a superconducting magnet system, which includes a backplate assembly 100 and a clamping assembly 200.

[0074] The backplate assembly 100 is used to connect the coil body 20 of the superconducting magnet system; the clamping assembly 200 includes a first insulating member 210, two clamping members 220 and a plurality of adjusting members 230. The first insulating member 210 forms a mounting cavity 211, which is used to accommodate at least the coil connector 30 of the superconducting magnet system. The first insulating member 210 is disposed between the two clamping members 220 and the clamping members 220 are connected to the backplate assembly 100. The plurality of adjusting members 230 are disposed around the first insulating member 210 and are respectively connected to the two clamping members 220 for adjusting the clamping force between the two clamping members 220.

[0075] It should be noted that the number and specific components of the adjusting element 230 can be designed according to actual needs, and this embodiment does not impose specific limitations on this. The adjusting element 230 includes, but is not limited to, bolts; for example, the bolts are M16x100. The clamping element 220 is made of materials including, but not limited to, stainless steel. The first insulating element 210 includes, but is not limited to, using G11 insulating material. G11 insulating material is a high-performance epoxy glass cloth laminate, belonging to thermosetting composite materials, which has excellent electrical properties, mechanical strength, and heat resistance.

[0076] Understandably, on the one hand, the backplate assembly 100 provides additional support and positioning through the coil body 20, reducing displacement of the backplate assembly 100 due to the electromagnetic load generated by the coil body 20 during operation, thereby ensuring the overall structural stability of the superconducting magnet system. On the other hand, by placing the coil connector 30 within the mounting cavity 211, the coil connector 30 can be effectively positioned and protected using a relatively enclosed space, while the insulation performance of the first insulating member 210 improves the electrical insulation performance of the coil connector 30. Furthermore, adjusting the clamping force between the two clamping members 220 through multiple adjusting members 230 not only improves the uniformity and stability of clamping but also facilitates maintenance and disassembly.

[0077] The installation and positioning device 10 for superconducting magnet systems provided in this embodiment of the invention performs multiple positioning and fixing of the coil connector 30 through the back plate assembly 100 and the clamping assembly 200, thereby improving the mechanical stability and electrical insulation performance of the coil connector 30 and reducing the disassembly and maintenance costs.

[0078] In some embodiments, such as Figure 1 and Figure 2 As shown, the backplate assembly 100 includes a backplate 110 and a first connector 120. The side of the backplate 110 away from the coil body 20 is connected to the clamping member 220. The first connector 120 is partially inserted through the backplate 110 and wound around the coil body 20. The material of the backplate 110 includes, but is not limited to, stainless steel, and the first connector 120 includes, but is not limited to, a support winding tape.

[0079] Understandably, the back plate 110 is first tightly attached to the outer wall of the coil body 20, and then the first connector 120 is partially passed through and wound around the back plate 110 and around the outside of the coil body 20 to further fix the coil body 20 and the back plate 110, thereby reducing relative movement between the coil body 20 and the back plate assembly 100 during operation. At the same time, by adjusting the winding method and tightness of the first connector 120, it can also accommodate coil bodies 20 of different sizes and shapes, improving the versatility and flexibility of the installation and positioning device 10.

[0080] In some embodiments, such as Figure 3 As shown, the back plate 110 includes a main body 111 and a first reinforcing part 112. The main body 111 is disposed outside the coil body 20; the first reinforcing part 112 protrudes from the side of the main body 111 away from the coil body 20. A first connecting member 120 partially passes through the main body 111 and the first reinforcing part 112, and a portion of the first reinforcing part 112 is disposed between the two clamping members 220. The connection method between the first reinforcing part 112 and the main body 111 includes, but is not limited to, welding or threaded connection.

[0081] Understandably, the main body 111 fits against the coil body 20, providing direct mechanical support and a mounting base for the remaining components in the mounting and positioning device 10, ensuring the structural stability of the entire mounting and positioning device 10. The first reinforcing member protrudes from the side of the main body 111 away from the coil body 20 to increase the strength of the entire back plate 110, enabling it to withstand greater electromagnetic forces. Furthermore, since the two clamping members 220 are located outside the first reinforcing member 112, the two clamping members 220 can simultaneously clamp the first reinforcing member 112 and the first insulating member 210 by operating the adjusting member 230, improving positioning and clamping accuracy and ensuring the effective fixation of the coil connector 30.

[0082] Meanwhile, since the first connector 120 is partially inserted between the main body 111 and the first reinforcing part 112, that is, the clamping assembly 200 and the first connector 120 are located on both sides of the first reinforcing part 112, the entire mounting and positioning device 10 is made more compact while reducing interference between the first connector 120 and the clamping assembly 200.

[0083] In some embodiments, such as Figures 1 to 4 As shown, the coil body 20 is annular, with two clamping members 220 spaced apart along the axial direction of the coil body 20. The back plate 110 has an arc-shaped structure, and the first reinforcing part 112 extends circumferentially along the coil body 20. This maximizes the contact area between the main body 111 and the coil body 20, as well as between the first reinforcing part 112 and the clamping members 220, thereby improving the uniformity of stress distribution.

[0084] In some embodiments, such as Figure 3 As shown, multiple first reinforcing parts 112 are provided, and the multiple first reinforcing parts 112 are distributed sequentially along the distribution direction of the clamping member 220. It should be noted that the number and specific distribution of the first reinforcing parts 112 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0085] Understandably, by setting multiple first reinforcing parts 112, the strength of the heightening back plate 110 is increased, thereby improving structural stability and resistance to deformation.

[0086] In some embodiments, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, multiple clamping components 200 are provided, and the multiple clamping components 200 are distributed sequentially along the distribution direction of the clamping member 220. It should be noted that the number and specific distribution of the clamping components 200 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0087] It is understandable that by setting multiple clamping components 200 to simultaneously limit and fix multiple coil connectors 30, the structural compactness and application range of the installation and positioning device 10 are improved.

[0088] In some embodiments, such as Figure 1 and Figure 3 As shown, multiple clamping components 200 and multiple first reinforcing parts 112 correspond one-to-one to increase the structural strength of the entire mounting and positioning device 10 while making the entire structure as compact as possible.

[0089] In some embodiments, such as Figure 3As shown, the back plate 110 also includes a second reinforcing part 113. The second reinforcing part 113 protrudes from the side of the main body 111 away from the coil body 20 and is connected to the first reinforcing part 112. The extending direction of the second reinforcing part 113 is perpendicular to the extending direction of the first reinforcing part 112. The first connecting member 120 partially passes between the main body 111 and the second reinforcing part 113. The connection methods between the second reinforcing part 113 and the main body 111 and the first reinforcing part 112 include, but are not limited to, welding or threaded connection.

[0090] Understandably, the mechanical strength of the entire backplate 110 is further increased by vertically arranged and located on the same side of the first reinforcing part 112 and the second reinforcing part 113. At the same time, since the first connecting member 120 partially passes between the main body part 111 and the second reinforcing part 113, that is, the clamping assembly 200 and the first connecting member 120 are respectively located on both sides of the second reinforcing part 113, the entire mounting and positioning device 10 is made more compact while reducing interference between the first connecting member 120 and the clamping assembly 200.

[0091] In some embodiments, combined with Figures 4 to 6 As shown, the coil body 20 is annular, the first reinforcing part 112 extends circumferentially along the coil body 20, and the extension direction of the second reinforcing part 113 is parallel to the axial direction of the coil body 20.

[0092] In some embodiments, combined with Figure 1 and Figure 3 As shown, the second reinforcing part 113 has a first clearance groove, the opening of the first clearance groove facing away from the main body part 111, and the first reinforcing part 112 is partially disposed in the first clearance groove. It should be noted that the shape and size of the first clearance groove can be designed according to actual needs, and this embodiment does not impose specific limitations on it.

[0093] Understandably, by embedding the first reinforcing part 112 into the second reinforcing part 113 through the first clearance groove, the entire back panel assembly 100 becomes more compact, and the connection strength between the first reinforcing part 112 and the second reinforcing part 113 is increased, thereby improving the structural stability of the back panel 110. Simultaneously, the opening of the first clearance groove faces away from the main body 111, meaning the first reinforcing part 112 is further away from the first connector 120 than the second reinforcing part 113. This allows the first connector 120 to pass through the first reinforcing part 112 and the main body 111, as well as the second reinforcing part 113 and the main body 111, simplifying the connection between the first connector 120 and the back panel 110.

[0094] In some embodiments, combined with Figure 1 and Figure 2As shown, the clamping member 220 has a second clearance groove 2201, and the second reinforcing part 113 is partially disposed within the second clearance groove 2201. It should be noted that the shape and size of the second clearance groove 2201 can be designed according to actual needs, and this embodiment does not impose specific limitations on it.

[0095] Understandably, by embedding the second reinforcing part 113 into the clamping member 220 through the second clearance groove 2201, the structure of the entire mounting and positioning device 10 becomes more compact, and the connection strength between the back plate 110 and the clamping member 220 is increased, thereby improving the structural stability of the mounting and positioning device 10. Furthermore, the insertion fit between the second clearance groove 2201 and the second reinforcing part 113 improves the positioning accuracy between the back plate 110 and the clamping member 220, achieving multiple positioning and fixation of the coil connector 30.

[0096] In some embodiments, combined with Figure 3 As shown, multiple second reinforcing portions 113 are provided, and these multiple second reinforcing portions 113 are spaced apart along the extending direction of the first reinforcing portion 112 to further improve the overall strength and positioning accuracy of the back plate 110. It should be noted that the number and specific distribution of the second reinforcing portions 113 can be designed according to actual needs, and this embodiment does not impose specific limitations on this.

[0097] In some embodiments, combined with Figure 2 As shown, the clamping member 220 includes a first part 221 and a second part 222 connected together. The first part 221 abuts against the first reinforcing part 112, and the second part 222 abuts against the first insulating member 210 and is connected to the adjusting member 230. Both the first part 221 and the second part 222 are provided with adjusting members 230. Exemplarily, the first part 221 and the second part 222 are integrally formed structures.

[0098] It is understood that the first part 221 is disposed on the side of the second part 222 near the coil body 20, that is, the first part 221 and the first reinforcing part 112 abut against each other, and the preload between them is adjusted by the adjusting member 230 disposed on the first part 221; the second part 222 abuts against the first insulating member 210, and the preload between them is adjusted by the adjusting member 230 disposed on the second part 222, thereby maximizing the strength of the connection between the back plate assembly 100 and the clamping assembly 200.

[0099] In some embodiments, combined with Figure 2 As shown, the clamping assembly 200 further includes a second insulating member 240, which is disposed between the two clamping members 220, and at least a portion of the adjusting member 230 passes through the second insulating member 240. The second insulating member 240 includes, but is not limited to, using G11 insulating material.

[0100] Understandably, by providing a second insulator 240 between the two clamping members 220, the insulation performance of the clamping assembly 200 is further enhanced, ensuring sufficient electrical insulation between the coil connector 30 and the backplate assembly 100, thereby improving the reliability of the mounting and positioning device 10. Simultaneously, since at least one end of the adjusting member 230 passes through one of the clamping members 220 and the second insulator 240 and engages with the other clamping member 220, the structural stability of the clamping assembly 200 is further enhanced, enabling it to better withstand the forces (including but not limited to electromagnetic forces and thermal stresses) generated during the operation of the coil (including the coil body 20 and the coil connector 30).

[0101] In some embodiments, combined with Figures 1 to 3 As shown, the second insulating member 240 is spaced apart from the first reinforcing part 112 and is disposed between the first portions 221 of the two clamping members 220.

[0102] It is understandable that the second insulating member 240 is disposed on the side of the first insulating member 210 near the back plate assembly 100, that is, the first reinforcing part 112 and the second insulating member 240 are both located between the two first parts 221. This not only balances the center of gravity distribution of the clamping assembly 200, but also enhances the insulation performance and structural strength of the clamping assembly 200, and facilitates the maintenance and disassembly of the coil connector 30.

[0103] In some embodiments, combined with Figure 5 and Figure 6 As shown, the mounting and positioning device 10 also includes a second connector 300, which passes between the backplate assembly 100 and the clamping assembly 200 and is wound around the coil body 20. The second connector 300 includes, but is not limited to, a fiberglass tape.

[0104] It is understandable that the back plate 110 is first attached to the outside of the coil body 20, then the first connector 120 is wrapped around the outside of the main body 111 and the coil body 20, and finally the second connector 300 is partially passed between the first connector 120 and the first reinforcing part 112 to be wrapped around the outside of the first connector 120, thereby further enhancing the structural stability and compactness of the entire mounting and positioning device 10.

[0105] In some embodiments, combined with Figure 5 and Figure 6 As shown, the mounting and positioning device 10 also includes a mounting member 400, which is disposed on the backplate assembly 100 and used to position the cooling pipe 40 of the superconducting magnet system. The mounting cavity 211 is also used to accommodate a portion of the cooling pipe 40. The connection between the mounting member 400 and the backplate assembly 100 includes, but is not limited to, resin adhesive.

[0106] It is understandable that the cooling pipe 40 is supported and fixed by the mounting component 400 to reduce the possibility of displacement of the cooling pipe 40 during coil operation, and to ensure that the coolant can flow smoothly between the cooling pipe 40 and the coil, thereby effectively controlling the temperature of the coil and improving the reliability of the entire mounting and positioning device 10.

[0107] In some embodiments, such as Figure 5 , Figure 6 and Figure 8 As shown, the mounting and positioning device 10 also includes a third insulating element 500, which is sleeved outside the cooling pipe 40 portion and disposed close to the mounting member 400 to provide additional electrical isolation between the cooling pipe 40 and the mounting member 400 or other conductive components, thereby improving the electrical safety and operational stability of the mounting and positioning device 10.

[0108] In some embodiments, combined with Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the coil connector 30 forms two second flow channels, and the cooling pipe 40 forms a third flow channel. The third flow channel within the mounting cavity 211 is further divided into two sub-flow channels. The outlet of one sub-flow channel is connected to the inlet of one of the second flow channels, and the outlet of the other sub-flow channel is connected to the outlet of the other second flow channel. This improves heat exchange efficiency while making the overall structure more compact. Exemplarily, the two second flow channels are arranged along the distribution direction of the clamping member 220, and the outlets of the two second flow channels are arranged opposite each other circumferentially along the coil body 20 to reduce mutual interference. Of course, in other embodiments, the number of second flow channels formed by the coil connector 30 can be designed according to actual needs; this embodiment does not impose specific limitations on this.

[0109] In some embodiments, such as Figure 5 and Figure 6 As shown, the mounting component 400 and the clamping assembly 200 are located on the wall surfaces of the backplate assembly 100 in different directions.

[0110] Understandably, the mounting component 400 is located on the side of the backplate assembly 100 away from the end wall of the coil body 20, and the clamping component 200 is located on the side of the backplate assembly 100 away from the outer side wall of the coil body 20, thus forming a multi-directional support structure, improving the structural stability of the entire mounting and positioning device 10, optimizing the spatial layout, making the entire mounting and positioning device 10 more compact, reducing the risk of interference, and facilitating the separate maintenance of the cooling pipe 40 and the coil connector 30.

[0111] In some embodiments, such as Figure 5 and Figure 6As shown, the second connector 300 is partially inserted through the mounting member 400 to further enhance the connection strength between the second connector 300, the first connector 120 and the mounting member 400, improve the mechanical strength of the entire mounting and positioning device 10, and reduce the risk of the cooling pipe 40 and the coil connector 30 shifting due to coil operation.

[0112] In some embodiments, such as Figure 5 and Figure 6 As shown, multiple second connectors 300 and mounting members 400 are provided, and the multiple second connectors 300, multiple mounting members 400, and multiple clamping components 200 correspond one-to-one. For example, the multiple second connectors 300 and multiple mounting members 400 are distributed at intervals along the circumference of the coil body 20.

[0113] In some embodiments, such as Figure 7 and Figure 8 As shown, the mounting component 400 includes a base 410, a first fixing block 420, a second fixing block 430, and a tensioning member 440. The base 410 is disposed on the back plate assembly 100. The first fixing block 420 and the second fixing block 430 are disposed on the base 410 and spaced apart for positioning the cooling pipe 40. The second connecting member 300 passes through the first fixing block 420 and the second fixing block 430 respectively. The tensioning member 440 is disposed on the base 410 and located on the side of the second fixing block 430 away from the first fixing block 420 for tensioning the second connecting member 300.

[0114] It should be noted that the connection between the base 410 and the backplate assembly 100 includes, but is not limited to, resin adhesive bonding. The connection between the first fixing block 420 and the second fixing block 430 and the base 410 includes, but is not limited to, welding or threaded connection.

[0115] Understandably, the base 410 is positioned on the backplate assembly 100 to securely transfer the entire mounting component 400 and its load (vibration of the cooling pipe 40, preload of the second connector 300, etc.) to the backplate assembly 100, facilitating centralized load management, improving overall rigidity, and simplifying assembly and disassembly. The first fixing block 420 and the second fixing block 430 are spaced apart to provide two-point positioning for the cooling pipe 40, improving resistance to torsion and bending, and increasing long-term reliability. Simultaneously, the second connector 300 passes through the first fixing block 420 and the second fixing block 430 respectively, allowing for a more compact structure between the mounting component 400 and the second connector 300, optimizing the layout. Furthermore, the tensioner 440 applies stable tension to the second connector 300, effectively resisting vibration, enhancing the structural stability and compactness of the entire mounting and positioning device 10, and simplifying the installation process of the second connector 300.

[0116] In some embodiments, such as Figure 8 As shown, along the axial direction of the coil body 20, the projection of the third insulating member 500 is located between the first fixing block 420 and the second fixing block 430, so that the third insulating member 500 is sleeved on the part of the cooling pipe 40 located between the first fixing block 420 and the second fixing block 430, effectively isolating the cooling pipe 40 from the surrounding conductive components, further reducing the risk of short circuit and improving the reliability of the installation positioning device 10.

[0117] In some embodiments, such as Figure 7 As shown, the tensioning member 440 includes a roller 441 and a limiting member 442. The roller 441 is rotatably disposed on the base 410, and the limiting member 442 is detachably disposed between the roller 441 and the base 410. Exemplarily, the limiting member 442 includes, but is not limited to, a nut.

[0118] Understandably, when the limiting member 442 is removed, the second connecting member 300 is positioned around the roller 441, and the tension of the second connecting member 300 is adjusted by rotating the roller 441. When the limiting member 442 is installed, the limiting member 442 constrains the roller 441 to rotate relative to the base 410, thereby maintaining the current tension of the second connecting member 300 and improving the operational efficiency and reliability of tension adjustment.

[0119] In some embodiments, such as... Figure 7 As shown, the roller 441 has an installation slot, and the second connector 300 passes through the installation slot so that the second connector 300 can be wound around the outside of the roller 441, ensuring the consistency of installation, improving the tension control accuracy, and ensuring the orderly overlapping of the second connector 300 on the roller 441.

[0120] In some embodiments, such as Figure 7 As shown, the mounting component 400 also includes a pressure plate 450, which is disposed on the base 410 and located between the first fixing block 420 and the second fixing block 430. The second connecting component 300 is partially disposed between the pressure plate 450 and the base 410.

[0121] Understandably, by setting the pressure plate 450, the uniform surface pressure applied to the second connector 300 can be reduced, which facilitates the reduction of machining and assembly accuracy requirements, simplifies the assembly process, and guides the installation of the second connector 300.

[0122] In some embodiments, such as Figure 7As shown, the pressure plate 450 has multiple spaced guide slots, and the second connector 300 passes through each guide slot. That is, the second connector 300 passes through each guide slot, causing the portion of the second connector 300 located on the pressure plate 450 to form a wave-like shape. This provides elastic deformation capability and stroke compensation range, compensates for significant tolerances and wear, and acts as a buffer and shock absorber. It also increases the contact area between the second connector 300 and the pressure plate 450, improving the reliability between them.

[0123] In some embodiments, such as Figure 7 As shown, the pressure plate 450 and the base 410 are screwed together, that is, the pressure plate 450 and the base 410 are connected by bolts. This not only facilitates the installation of the second connector 300, but also facilitates the adjustment of the preload between the pressure plate 450 and the base 410 by bolts, thereby improving reliability.

[0124] In some embodiments, such as Figure 7 As shown, the mounting component 400 also includes a guide cylinder 460, which is disposed on the base 410 and located on the side of the tensioner 440 away from the second fixing block 430. The second connector 300 and the cooling pipe 40 are respectively located on both sides of the guide cylinder 460.

[0125] Understandably, the first fixing block 420, pressure plate 450, second fixing block 430, tensioning member 440, and guide cylinder 460 are sequentially and spaced apart on the base 410. On one hand, the second connecting member 300 is located on the side of the guide cylinder 460 closer to the back plate assembly 100, and the cooling pipe 40 is located on the side of the guide cylinder 460 away from the back plate assembly 100, thereby reducing interference between the two and facilitating the bending of the second connecting member 300 so that the second connecting member 300 can be wrapped around the first connecting member 120, thus enhancing rigidity and reliability.

[0126] This invention also provides a superconducting magnet system.

[0127] like Figures 4 to 6 As shown, the superconducting magnet system includes a coil body 20, a coil connector 30, and the aforementioned mounting and positioning device 10.

[0128] The coil body 20 forms a first flow channel; the coil connector 30 is connected to the coil body 20 and forms a second flow channel, the outlet of the second flow channel and the inlet of the first flow channel are connected; the cooling pipe 40 is connected to the coil connector 30 and forms a third flow channel, the outlet of the third flow channel and the inlet of the second flow channel are connected. Exemplarily, the coil includes, but is not limited to, at least one of a poloidal field coil (PF coil), a tokamak field coil (TF coil), and an induction coil (EF coil).

[0129] It should be noted that the coolant at a lower temperature flows into the second flow channel formed by the coil connector 30 through the third flow channel formed by the cooling pipe 40, and then enters the first flow channel formed by the coil body 20 before flowing out, thus completing one cooling cycle for the coil.

[0130] In some embodiments, such as Figure 4 As shown, the superconducting magnet system includes two mounting and positioning devices 10, which are symmetrically arranged on the coil body 20 to further improve the uniformity of stress distribution in the superconducting magnet system and enhance heat exchange efficiency. Of course, in other embodiments, more than two mounting and positioning devices 10 may be provided; this embodiment does not impose specific limitations on the number or distribution of the mounting and positioning devices 10.

[0131] The superconducting magnet system provided by the present invention improves the stability of the superconducting magnet system operation and reduces the disassembly and maintenance costs by repeatedly positioning and fixing the coil connector 30.

[0132] This invention also provides a fusion reactor device, including the superconducting magnet system described above.

[0133] It should be noted that fusion reactor devices also include, but are not limited to, Dewar systems, cold shield systems, vacuum chamber systems, divertor systems, blanket systems, remote operating systems, and maintenance systems.
