[0002] Producing energy through magnetic confinement fusion is considered the most promising solution to humanity's energy crisis. The tokamak is one of the most successful approaches to magnetic confinement fusion research. Its main structure consists primarily of a divertor, blanket, vacuum chamber, cryostat, cold shield, and magnets.

The cold shield is a metal structure installed between the vacuum chamber and the low-temperature superconducting magnets to shield thermal radiation and reduce heat load. During final assembly of the tokamak, the vacuum chamber and cold shield must first be assembled into a 1 / 8 ring structure in a pre-assembly hall.

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

[0027] Reference below Figures 1-6 , describing a supporting device 100 according to an embodiment of the present invention.

[0028] like Figures 1 to 3As shown, a support device 100 according to an embodiment of the present invention is used to support a vacuum chamber 200 and a 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 adjustment member 30. The first support assembly 10 includes a first clamping member 11, a first support member 12, and a first adjustment 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 adjustment member 13. The first adjustment 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 adjustment 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 adjustment member 23. The second adjustment member 23 can adjust the distance between the second clamping member 21 and the second support member 22 in the first direction; the third adjustment 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.

[0029] During the assembly of the 1 / 8 ring structure, the first support assembly 10 can be used to clamp the cold shield 300, that is, the first clamping member 11 and the first support member 12 are adjusted in the first direction (see Figure 3 The second support assembly 20 is used to clamp the vacuum chamber 200. Specifically, the second adjustment member 23 adjusts the distance between the second clamping member 21 and the second support member 22 to clamp the edge of the vacuum chamber 200. The third adjustment member 30 then adjusts the distance between the first support member 12 and the second clamping member 21 in the first direction, thereby adjusting the gap between the cold shield 300 and the vacuum chamber 200, maintaining the gap at the target value.

[0030] A plurality of supporting devices 100 may be arranged along the ring of the 1 / 8 ring structure, thereby supporting the cold shield 300 and the vacuum chamber 200 at multiple positions.

[0031] The first adjusting member 13 , the second adjusting member 23 and the third adjusting member 30 may refer to components with an adjusting function, and may be, but are not limited to, bolts, studs, cylinders, hydraulic rods, electric push rods, and the like.

[0032] According to the supporting device 100 of the embodiment of the present invention, the first supporting assembly 10, the second supporting assembly 20 and the third adjusting member 30 can clamp the cold shield 300 and the vacuum chamber 200, and adjust the gap between the cold shield 300 and the vacuum chamber 200 without interfering with the subsequent assembly of the low-temperature magnet. This can improve the installation reliability during the assembly process of the cold shield 300 and the vacuum chamber 200.

[0033] In some embodiments of the present invention, Figures 3 to 5 As shown, the dimension of the first support member 12 in the second direction is greater than that 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 shield 300 .

[0034] The second direction can be Figures 3 to 5 The front and rear directions, the first direction can be Figures 3 to 5 It can be understood that the first support member 12 supports the side of the cold shield 300 close to the gap, and the first clamping member 11 clamps the other side of the cold shield 300 outside the gap. Since 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, a larger supporting surface is provided between the first support member 12 and the cold shield 300, which can improve the support stability and reliability of the cold shield 300.

[0035] In some embodiments of the present invention, 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 adjusting member 13, and 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.

[0036] In the above technical solution, the first support member 12 includes a first portion 121 and a second portion 122, thereby forming a stepped surface structure on the first support member 12. During the assembly process of the nuclear fusion device, eight 1 / 8 ring structures need to be spliced ​​into a complete ring, and the cold shields 300 of two adjacent 1 / 8 ring structures are connected by flanges 301 (see FIG. Figure 2 ), and the flange 301 is connected to another cold shield 300 via fastening bolts 302. Thus, by configuring the first support member 12 with the above structure, the first portion 121 can be supported on the cold shield 300, and the second portion 122 can be supported on the flange 301, thereby increasing support stability and providing more reliable support.

[0037] In some embodiments of the present invention, Figures 3 to 5 As shown, a first step portion 111 is provided on one side of the first clamping member 11 close to the first portion 121 . The first step portion 111 includes a first clamping surface 111 a and a first limiting surface 111 b that are adjacent and connected. The first clamping surface 111 a faces the first portion 121 .

[0038] It can be understood that the first clamping member 11 clamps the outer side of the cold shield 300, and is usually clamped on the flange 301 in cooperation with the second part 122. By forming the first step portion 111 on the first clamping member 11, the first clamping surface 111a can be abutted against the outer side of the flange 301 away from the gap, and the first limiting surface 111b can be abutted against the side of the flange 301 away from the cold shield 300 and play a limiting role, so 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 shield 300 (see Figure 2 ), which is beneficial to reducing the risk of wear caused by contact between the first support member 12 and the edge surface 303 during the clamping process. The cold shield 300, as a cooling component, should be kept as intact as possible without damage, while the flange 301, as a connecting structure, does not have such concerns. It can be seen that this method can improve the safety of the cold shield 300.

[0039] In some embodiments of the present invention, Figure 2 and Figure 4 As shown, the first support member 12 is provided with bolt locating holes 12a. These holes 12a cooperate with the fastening bolts 302 on the flange 301 to provide a position limiter, improving the connection reliability between the first support member 12 and the cold shield 300, reducing the risk of displacement, and enhancing support reliability. Optionally, there may be one or more bolt locating holes 12a, but this is not limited to one. For example, four bolt locating holes 12a may be provided on the first support member 12. Alternatively, the bolt locating holes 12a may be provided on the first portion 121.

[0040] In some embodiments of the present invention, Figure 5 As shown, the first surface 11a of the first clamping member 11, which is away from the first adjusting member 13, and the second surface 121a of the first portion 121, which is away from the first adjusting member 13, are aligned. This approach minimizes the size of the first portion 121 while ensuring that the first clamping member 11 and the first portion 121 jointly clamp the flange 301 of the cold shield 300. This saves material and reduces the overall weight and size of the support device 100, thereby simplifying the assembly of the support device 100 and the cold shield 300.

[0041] 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 size of the cold screen clamping area in the second direction is 30 mm to 70 mm, and the size in the third direction is 120 mm to 200 mm. The third direction, the second direction and the first direction are perpendicular to each other.

[0042] like Figures 3 to 5 As shown, as an example, the third direction may be a left-right direction.

[0043] It can be understood that by setting the dimensions of the cold shield clamping area in the second and third directions within the aforementioned ranges, the cold shield clamping area can be appropriately sized. This can prevent the cold shield 300 from being damaged by excessive force and unstable clamping due to a too small clamping area. It can also prevent the first support assembly 10 from being too large and inconvenient to assemble due to a large clamping area. In other words, by setting the cold shield clamping area within the aforementioned ranges, reliable clamping can be ensured, damage to the cold shield 300 can be avoided, and installation of the first support assembly 10 and the cold shield 300 can be facilitated.

[0044] In some embodiments of the present invention, Figure 3 and Figure 5 As shown, a second step portion 211 is provided on the side of the second clamping member 21 close to the second support member 22, and the second step portion 211 includes adjacent and connected second clamping surfaces 211a and second limiting surfaces 211b. A third step portion 221 is provided on the side of the second support member 22 close to the second clamping member 21, and the third step portion 221 includes adjacent and connected first supporting surfaces 221a and third limiting surfaces 221b. The first supporting surface 221a is opposite to the second clamping surface 211a, and the third limiting surface 221b and the second limiting surface 211b are arranged close to the second adjusting member 23.

[0045] The second clamping surface 211a and the first supporting surface 221a can cooperate with each other to clamp and support the vacuum chamber 200. The second limiting surface 211b and the third limiting surface 221b can contact the side end surface 201 of the vacuum chamber 200, thereby preventing the second clamping member 21 and the second supporting member 22 from entering too deep into the vacuum chamber 200 and contacting other components, thereby preventing the second clamping member 21 and the second supporting member 22 from damaging other components of the vacuum chamber 200. For example, a rib 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 rib plate 202 can be prevented from contacting.

[0046] In some embodiments of the present invention, 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 an isolation gasket 40.

[0047] In the above technical solution, the isolation gasket 40 prevents the second clamping surface 211a, the second limiting surface 211b, the first support surface 221a, and the third limiting surface 221b from directly contacting the vacuum chamber 200. It also prevents the first clamping surface 111a, the first limiting surface 111b, the first portion 121, and the second portion 122 from directly contacting the cold shield 300, thereby avoiding the risk of material contamination due to contact. Furthermore, the isolation gasket 40 also increases friction with the cold shield 300 or the vacuum chamber 200, reducing the risk of the first clamping member 11 and the first support member 12 slipping against the cold shield 300, as well as the risk of the second clamping member 21 and the second support member 22 slipping against the vacuum chamber 200.

[0048] Optionally, the isolation gasket 40 is adhesively connected 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 portion 121, and the second portion 122. This connection method is relatively simple, can reduce costs, and is also convenient to operate.

[0049] In some embodiments of the present invention, the isolation gasket 40 is a contoured member with elasticity and an insulating material.

[0050] It is understood that, because the cold shield 300 and vacuum chamber 200 are curved structures, the isolation gasket 40 is a resilient contoured member. This allows the isolation gasket 40 to better adhere to the corresponding cold shield 300 or vacuum chamber 200. Furthermore, the elasticity of the isolation gasket 40 allows it to adapt to the different curvatures of the cold shield 300 or vacuum chamber 200, better meeting the clamping and support requirements at different locations. For example, for locations with large curvatures of the cold shield 300 or vacuum chamber 200, the isolation gasket 40 can be a curved contoured member with a larger surface; for locations with small curvatures of the cold shield 300 or vacuum chamber 200, the isolation gasket 40 can be a curved contoured member with a smaller surface; and for linear locations of the cold shield 300 or vacuum chamber 200, the isolation gasket 40 is linear.

[0051] Secondly, the isolation gasket 40 is also made of insulating material and has insulation properties to prevent current conduction between the support device 100 and the cold shield 300 or the vacuum chamber 200 , thereby preventing the cold shield 300 or the vacuum chamber 200 from being charged.

[0052] Alternatively, the isolation gasket 40 may be made of a composite fiberglass material. This material not only provides good elasticity and insulation, but also allows it to withstand greater pressure and tension, preventing it from being crushed or cracked, thereby improving its operational reliability.

[0053] In some embodiments of the present invention, the second clamping member 21 has a larger dimension in the second direction than the second supporting member 22 . The second direction is perpendicular to the first direction and points to the gap between the vacuum chamber 200 and the cold shield 300 .

[0054] It is understood that the second clamping member 21 clamps on one side of the vacuum chamber 200 located within the gap, while the second support member 22 supports the other side of the vacuum chamber 200 located outside the gap. When the third adjustment member 30 drives the second clamping member 21 away from the first support member 12, the second clamping member 21 acts on the vacuum chamber 200. Because the second clamping member 21 has a larger dimension in the second direction than the second support member 22, the second clamping member 21 has a larger contact surface with the vacuum chamber 200, which can reduce the force per unit area of ​​the second clamping member 21, avoid the risk of stress concentration on the vacuum chamber 200, and improve the reliability of the second clamping member 21's support of the vacuum chamber 200.

[0055] In some embodiments of the present invention, a vacuum chamber clamping area is formed between the second clamping member 21 and the second support member 22. The size of the vacuum chamber clamping area in the second direction is 60mm~120mm, and the size in the third direction is 120mm~200mm. The third direction, the second direction and the first direction are perpendicular to each other.

[0056] It will be appreciated that by setting the dimensions of the vacuum chamber clamping area in the second and third directions within the aforementioned ranges, the vacuum chamber clamping area can be appropriately sized. This prevents damage to the vacuum chamber 200 caused by excessive force applied to the clamping area due to a too small clamping area, as well as insecure clamping. It also prevents the second support assembly 20 from being too large and inconvenient to assemble due to a large clamping area. In other words, by setting the vacuum chamber clamping area within the aforementioned ranges, secure clamping can be ensured, damage to the vacuum chamber 200 can be avoided, and installation of the second support assembly 20 and the vacuum chamber 200 can be facilitated.

[0057] 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 push rod, a hydraulic cylinder, and a jack. It is understood that the above-described structures of the first adjusting member 13, the second adjusting member 23, and the third adjusting member 30 provide more options to meet different needs.

[0058] 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 the first direction. For example, the first adjusting member 13, the second adjusting member 23, and the third adjusting member 30 can be bolts, screw rods, electric push rods, etc.

[0059] Alternatively, as Figures 3 to 6As shown, the first adjusting member 13, the second adjusting member 23, and the third adjusting member 30 are bolts, wherein the first adjusting member 13 is threadedly connected to the first clamping member 11 and the first support member 12, the second adjusting member 23 is threadedly connected to the second clamping member 21 and the second support member 22, and the third adjusting member 30 is threadedly connected to the first clamping member 11 and the first support member 12. Using the first adjusting member 13, the second adjusting member 23, and the third adjusting member 30 as bolts can make the overall installation and disassembly of the support device 100 relatively simple, and the adjustment method is also simpler. Simpler adjusting members can also reduce the probability of failure and improve the reliability of the entire device.

[0060] 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 the second direction. For example, the first adjusting member 13, the second adjusting member 23, and the third adjusting member 30 are horizontally arranged hand jacks.

[0061] In some embodiments of the present invention, the first clamping member 11, the first support member 12, the first adjusting member 13, the second clamping member 21, the second support member 22, the second adjusting member 23, and the third adjusting member 30 are all made of the same material. It is understood that using the same material for all components can avoid the risk of material contamination. Optionally, the first clamping member 11, the first support member 12, the first adjusting member 13, the second clamping member 21, the second support member 22, the second adjusting member 23, and the third adjusting member 30 are all made of metal.
