[0002] Magnetic confinement fusion is considered the most likely way to solve humanity's energy crisis. Tokamak devices are among the most effective methods for studying magnetic confinement fusion energy. The main body of a tokamak device consists of a divertor, blanket, vacuum chamber, Dewar, cold shield, and magnet. The vacuum chamber is the core component of the plasma cavity in the fusion device, serving as the support and mounting interface for internal components. The cold shield is a metal structure installed between the vacuum chamber and the low-temperature superconducting magnet to shield against thermal radiation and reduce heat load. During the final assembly of the tokamak device, the vacuum chamber and cold shield must first be assembled into a 1 / 8 ring structure in a pre-assembly hall. Therefore, ensuring the reliability of the installation of this 1 / 8 ring structure is one of the urgent problems to be solved. Summary of the Invention

Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0049] The following is for reference. Figures 1-6 The following describes the support device 100 according to an embodiment of the present invention.

[0050] like Figures 1 to 3As shown, a support device 100 according to an embodiment of the present invention is used to support the vacuum chamber 200 and the cold shield 300 of a nuclear fusion device. The support device 100 includes a first support assembly 10, a second support assembly 20, and a third adjusting member 30. The first support assembly 10 includes a first clamping member 11, a first support member 12, and a first adjusting member 13. The first clamping member 11 and the first support member 12 are spaced apart along a first direction and connected by the first adjusting member 13. The first adjusting member 13 can adjust the distance between the first clamping member 11 and the first support member 12 in the first direction. The second support assembly 20 includes a second clamping member 21, a second support member 22, and a second adjusting member 23. The second clamping member 21 and the second support member 22 are spaced apart along the first direction and connected by the second adjusting member 23. The second adjusting member 23 can adjust the distance between the second clamping member 21 and the second support member 22 in the first direction. The third adjusting member 30 connects the first support member 12 and the second clamping member 21 and can adjust the distance between the first support member 12 and the second clamping member 21 in the first direction.

[0051] During the assembly of the 1 / 8 ring structure, the first support component 10 can be used to clamp the cold screen 300, that is, the first clamping component 11 and the first support component 12 can be adjusted in the first direction (see [reference]) by the first adjusting component 13. Figure 3 The distance between the first support member 21 and the second support member 22 (in the vertical direction) is adjusted to clamp the edge of the cold screen 300. The second support member 20 is used to clamp the vacuum chamber 200, that is, the distance between the second clamping member 21 and the second support member 22 is adjusted by the second adjusting member 23 to clamp the edge of the vacuum chamber 200. Then, the distance between the first support member 12 and the second clamping member 21 in the first direction can be adjusted by the third adjusting member 30, thereby adjusting the gap between the cold screen 300 and the vacuum chamber 200, so that the gap between the cold screen 300 and the vacuum chamber 200 is maintained at the target value.

[0052] Among them, multiple support devices 100 can be arranged along the ring of the 1 / 8 ring structure to support the cold screen 300 and the vacuum chamber 200 at multiple positions.

[0053] The first adjusting component 13, the second adjusting component 23, and the third adjusting component 30 can refer to components with adjusting functions, and can be, but are not limited to, bolts, studs, cylinders, hydraulic rods, electric actuators, etc.

[0054] According to the embodiment of the present invention, the support device 100 can clamp the cold screen 300 and the vacuum chamber 200 through the first support component 10, the second support component 20 and the third adjustment component 30, and adjust the gap between the cold screen 300 and the vacuum chamber 200, and does not interfere with the subsequent assembly of the low-temperature magnet, thereby improving the installation reliability during the assembly process of the cold screen 300 and the vacuum chamber 200.

[0055] In some embodiments of the present invention, such as Figures 3 to 5 As shown, the dimension of the first support member 12 in the second direction is larger than the dimension of the first clamping member 11 in the second direction. The second direction is perpendicular to the first direction and points to the gap between the vacuum chamber 200 and the cold screen 300.

[0056] The second direction can be Figures 3 to 5 The front and back directions, the first direction can be Figures 3 to 5 The vertical direction. It can be understood that the first support member 12 supports the cold screen 300 on the side near the gap, and the first clamping member 11 clamps the cold screen 300 on the other side outside the gap. Since the size of the first support member 12 in the second direction is larger than the size of the first clamping member 11 in the second direction, there is a larger support surface between the first support member 12 and the cold screen 300, which can improve the stability and reliability of the support for the cold screen 300.

[0057] In some embodiments of the present invention, such as Figures 3 to 5 The first support member 12 includes a first part 121 and a second part 122. The first part 121 is connected to the first adjustment member 13. In the first direction, the size of the first part 121 is larger than the size of the second part 122. In the second direction, the size of the first clamping member 11 is less than or equal to the size of the first part 121.

[0058] In the above technical solution, the first support member 12 includes a first part 121 and a second part 122, thereby forming a stepped surface structure on the first support member 12. During the assembly of the nuclear fusion device, eight 1 / 8 ring structures need to be spliced ​​together to form a complete ring, and the cold screens 300 of adjacent two 1 / 8 ring structures are connected by flanges 301 (see...). Figure 2 Furthermore, the flange 301 is connected to another cold screen 300 by fastening bolts 302. Thus, by setting the first support member 12 with the above structure, the first part 121 can be supported on the cold screen 300, and the second part 122 can be supported on the flange 301, thereby increasing the support stability and providing a more reliable support function.

[0059] In some embodiments of the present invention, such as Figures 3 to 5 As shown, the first clamping member 11 has a first step portion 111 on the side near the first part 121. The first step portion 111 includes an adjacent and connected first clamping surface 111a and a first limiting surface 111b, with the first clamping surface 111a facing the first part 121.

[0060] It is understandable that the first clamping member 11 clamps the outer side of the cold screen 300, and is usually clamped on the flange 301 in conjunction with the second part 122. A first step portion 111 is formed on the first clamping member 11, the first clamping surface 111a can abut against the outer side of the flange 301 away from the gap, and the first limiting surface 111b can abut against the side of the flange 301 away from the cold screen 300 and play a limiting role. This ensures that the step surface formed between the first part 121 and the second part 122 will not contact the edge surface 303 of the cold screen 300 (see...). Figure 2 This helps reduce the risk of wear caused by the first support 12 coming into contact with the edge surface 303 during the clamping process. As a cooling component, the cold screen 300 should be kept as intact as possible without damage, while the flange 301, as a connecting structure, does not have this concern. It can be seen that this method can improve the safety of the cold screen 300.

[0061] In some embodiments of the present invention, such as Figure 2 and Figure 4 As shown, the first support member 12 is provided with bolt positioning holes 12a. The bolt positioning holes 12a can cooperate with the fastening bolts 302 on the flange 301 to provide a limiting function, improving the connection reliability between the first support member 12 and the cold shield 300, reducing the risk of displacement, and thus improving support reliability. Optionally, there can be, but is not limited to, one or more bolt positioning holes 12a. For example, four bolt positioning holes 12a are provided on the first support member 12. Optionally, the bolt positioning holes 12a can be provided on the first part 121.

[0062] In some embodiments of the present invention, such as Figure 5 As shown, the first surface 11a of the first clamping member 11 away from the first adjusting member 13 and the second surface 121a of the first part 121 away from the first adjusting member 13 are flush. This method allows for minimizing the size of the first part 121 while ensuring that the first clamping member 11 and the first part 121 jointly clamp the flange 301 of the cold screen 300. This saves material, reduces the overall weight of the support device 100, and decreases its size, thus reducing the difficulty of assembling the support device 100 with the cold screen 300.

[0063] In some embodiments of the present invention, a cold screen clamping area is formed between the first clamping member 11 and the first support member 12. The cold screen clamping area has a size of 30mm to 70mm in the second direction and a size of 120mm to 200mm in the third direction. The third direction, the second direction and the first direction are perpendicular to each other.

[0064] like Figures 3 to 5 As shown, as an example, the third direction can be left or right.

[0065] Understandably, by setting the dimensions of the cold screen clamping area within the aforementioned range in the second and third directions, the cold screen clamping area can be made to have an appropriate size. This prevents damage to the cold screen 300 due to excessive force caused by an insufficiently small clamping area, as well as ensures a secure clamping. Conversely, it also prevents the first support component 10 from becoming too large and inconvenient to assemble due to an excessively large clamping area. In other words, setting the cold screen clamping area within the aforementioned range ensures clamping reliability, avoids damage to the cold screen 300, and facilitates the installation of the first support component 10 and the cold screen 300.

[0066] In some embodiments of the present invention, such as Figure 3 and Figure 5 As shown, the second clamping member 21 has a second step portion 211 on the side near the second support member 22. The second step portion 211 includes an adjacent and connected second clamping surface 211a and a second limiting surface 211b. The second support member 22 has a third step portion 221 on the side near the second clamping member 21. The third step portion 221 includes an adjacent and connected first support surface 221a and a third limiting surface 221b. The first support surface 221a is directly opposite the second clamping surface 211a. The third limiting surface 221b and the second limiting surface 211b are disposed near the second adjusting member 23.

[0067] The second clamping surface 211a and the first supporting surface 221a can cooperate to clamp and support the vacuum chamber 200. The second limiting surface 211b and the third limiting surface 221b can contact the side end face 201 of the vacuum chamber 200, thereby preventing the second clamping member 21 and the second supporting member 22 from entering the vacuum chamber 200 too deeply and contacting other components, and avoiding damage to other components of the vacuum chamber 200 by the second clamping member 21 and the second supporting member 22. For example, the vacuum chamber 200 is provided with a stiffening plate 202 (see...). Figure 2 Under the limiting action of the second limiting surface 211b and the third limiting surface 221b, the second support member 22 and the stiffener 202 can be prevented from contacting.

[0068] In some embodiments of the present invention, such as Figures 3 to 5 The second clamping surface 211a, the second limiting surface 211b, the first supporting surface 221a, the third limiting surface 221b, the first clamping surface 111a, the first limiting surface 111b, the first part 121, and the second part 122 are all provided with isolation pads 40.

[0069] In the above technical solution, the isolation gasket 40 can prevent the second clamping surface 211a, the second limiting surface 211b, the first supporting surface 221a, and the third limiting surface 221b from directly contacting the vacuum chamber 200, and prevent the first clamping surface 111a, the first limiting surface 111b, the first part 121, and the second part 122 from directly contacting the cold screen 300, thereby avoiding the risk of material contamination due to contact. Secondly, the isolation gasket 40 can also increase the friction with the cold screen 300 or the vacuum chamber 200, reducing the risk of the first clamping member 11 and the first supporting member 12 slipping from the cold screen 300, and reducing the risk of the second clamping member 21 and the second supporting member 22 slipping from the vacuum chamber 200.

[0070] Optionally, the isolation pad 40 is adhesively bonded to any one of the second clamping surface 211a, the second limiting surface 211b, the first supporting surface 221a, the third limiting surface 221b, the first clamping surface 111a, the first limiting surface 111b, the first part 121, and the second part 122. This connection method is relatively simple, reduces costs, and is easy to operate.

[0071] In some embodiments of the present invention, the insulating pad 40 is a flexible conforming part and an insulating material part.

[0072] Understandably, since the cold screen 300 and vacuum chamber 200 have curved structures, and the isolation pad 40 is a flexible contoured component, the isolation pad 40 can better fit against the corresponding cold screen 300 or vacuum chamber 200. Furthermore, the elasticity of the isolation pad 40 allows it to adapt to different curvatures of the cold screen 300 or vacuum chamber 200, better meeting the clamping and support requirements at different positions. For example, for positions with large curvature of the cold screen 300 or vacuum chamber 200, the isolation pad 40 can be a curved contoured component with a larger curvature; for positions with small curvature of the cold screen 300 or vacuum chamber 200, the isolation pad 40 can be a curved contoured component with a smaller curvature; and for straight positions of the cold screen 300 or vacuum chamber 200, the isolation pad 40 is straight.

[0073] Secondly, the isolation pad 40 is also an insulating material, which can prevent current conduction between the support device 100 and the cold screen 300 or the vacuum chamber 200, and prevent the cold screen 300 or the vacuum chamber 200 from becoming charged.

[0074] Optionally, the insulating gasket 40 can be made of composite fiberglass. Insulating gaskets 40 made of this material not only have good elasticity and insulation, but can also withstand greater pressure and tension, preventing them from being crushed or cracked, thereby improving their operational reliability.

[0075] In some embodiments of the present invention, the second clamping member 21 is larger in size in the second direction than the second support member 22 in the second direction, and the second direction is perpendicular to the first direction and points to the gap between the vacuum chamber 200 and the cold screen 300.

[0076] Understandably, the second clamping member 21 is clamped on one side of the vacuum chamber 200 located within the gap, while the second support member 22 supports the vacuum chamber 200 on the other side located outside the gap. When the third adjusting member 30 moves the second clamping member 21 away from the first support member 12, the second clamping member 21 acts on the vacuum chamber 200. Since the dimension of the second clamping member 21 in the second direction is larger than that of the second support member 22 in the second direction, the second clamping member 21 has a larger contact surface with the vacuum chamber 200. This reduces the force per unit area on the second clamping member 21 and avoids the risk of stress concentration on the vacuum chamber 200, thereby improving the reliability of the second clamping member 21 in supporting the vacuum chamber 200.

[0077] In some embodiments of the present invention, a vacuum chamber clamping region is formed between the second clamping member 21 and the second support member 22. The vacuum chamber clamping region has a dimension of 60mm to 120mm in the second direction and a dimension of 120mm to 200mm in the third direction. The third direction, the second direction and the first direction are perpendicular to each other.

[0078] Understandably, by setting the dimensions of the vacuum chamber clamping area within the aforementioned range in the second and third directions, the clamping area can be made to have an appropriate size. This prevents damage to the vacuum chamber 200 due to excessive force caused by an insufficiently small clamping area, as well as ensures secure clamping. Conversely, it also prevents the second support assembly 20 from becoming too large and inconvenient to assemble due to an excessively large clamping area. In other words, setting the vacuum chamber clamping area within the aforementioned range ensures clamping reliability, avoids damage to the vacuum chamber 200, and facilitates the installation of the second support assembly 20 and the vacuum chamber 200.

[0079] In some embodiments of the present invention, the first adjusting member 13, the second adjusting member 23, and the third adjusting member 30 are at least one of a threaded connector, a cylinder, an electric actuator, a hydraulic cylinder, and a jack. It is understood that the above-described structure of the first adjusting member 13, the second adjusting member 23, and the third adjusting member 30 provides more options to meet different needs.

[0080] In some embodiments of the present invention, the first adjusting member 13, the second adjusting member 23, and the third adjusting member 30 are configured to be movable and adjustable along a first direction. For example, the first adjusting member 13, the second adjusting member 23, and the third adjusting member 30 can be bolts, lead screws, electric actuators, etc.

[0081] Optionally, such as Figures 3 to 6As shown, the first adjusting member 13, the second adjusting member 23, and the third adjusting member 30 are bolts. The first adjusting member 13 is threadedly connected to the first clamping member 11 and the first supporting member 12; the second adjusting member 23 is threadedly connected to the second clamping member 21 and the second supporting member 22; and the third adjusting member 30 is threadedly connected to the first clamping member 11 and the first supporting member 12. Using bolts for the first adjusting member 13, the second adjusting member 23, and the third adjusting member 30 simplifies the overall installation and disassembly of the support device 100, and also simplifies the adjustment method. The simpler adjusting members also reduce the probability of malfunctions and improve the overall reliability of the device.
