Therefore, they should not be construed as limitations on this invention.

[0030] The tokamak device 1000 of the present invention is described below with reference to the accompanying drawings.

[0031] like Figure 1 As shown, a tokamak device 1000 according to an embodiment of the present invention includes: a vacuum chamber 100, a divertor 200, a first support assembly 300, and a second support assembly 400.

[0032] The vacuum chamber 100 provides a sealed vacuum environment for the fusion reaction, isolates external air impurities from interference, and ensures the stable existence of plasma. At the same time, as the supporting substrate of the tokamak device 1000, it can not only contain and confine the high-temperature fusion plasma, shield the heat load and particle irradiation, and coordinate the particle transport and operation condition control, but also facilitate the support and installation of other components of the tokamak device 1000 (such as the divertor 200, the first wall, etc.), ensuring the stable operation of the tokamak device 1000.

[0033] In some embodiments, combined with Figure 1 and Figure 2 As shown, the vacuum chamber 100 is provided with a maintenance window 110. The maintenance window 110 can reduce the installation difficulty of other components of the tokamak device 1000 (such as the divertor 200, the first wall, etc.), and facilitate the installation, maintenance and disassembly of other components of the tokamak device 1000 in the vacuum chamber 100.

[0034] Combination Figure 1 and Figure 2 As shown, the divertor 200 is disposed inside the vacuum chamber 100. The vacuum chamber 100 is used to support the divertor 200, ensuring the positional stability of the divertor 200.

[0035] Combination Figures 2-6 As shown, the first support assembly 300 is disposed between the outer side of the divertor 200 and the inner wall of the vacuum chamber 100 and includes a first support member 310 and a first mating member 320. The first support member 310 is fixedly connected to the inner wall of the vacuum chamber 100. The first end of the first mating member 320 is rotatably connected to the divertor 200, and the second end of the first mating member 320 is detachably connected to the first support member 310. The first mating member 320 can drive the divertor 200 to rotate, so that the divertor 200 has an initial position and a fixed position. In the fixed position, the second end of the first mating member 320 is fixedly connected to the first support member 310 and the divertor 200, respectively. This facilitates the fixed connection between the divertor 200 and the first support assembly 300, thereby enabling the first support assembly 300 to support the divertor 200, improving the positional stability of the divertor 200, and achieving the purpose of fixing the divertor 200.

[0036] Meanwhile, by fixing the first support member 310 to the inner wall of the vacuum chamber 100, the vacuum chamber 100 can support the first support member 310, ensuring the positional stability of the first support member 310; by setting the first end of the first mating member 320 to be rotatably connected to the divertor 200, the first mating member 320 can rotate relative to the divertor 200, reducing the difficulty of rotating the first mating member 320 relative to the divertor 200; by setting the second end of the first mating member 320 to be detachably connected to the first support member 310, the difficulty of installing and disassembling the second end of the first mating member 320 to the first support member 310 can be reduced.

[0037] Furthermore, by using the first mating member 320 to drive the divertor 200 to rotate, the difficulty of rotating the divertor 200 can be reduced, thereby reducing the difficulty of the divertor 200 from the initial position to the fixed position. In the fixed position, the second end of the first mating member 320 is set to be fixedly connected to the first support member 310 and the divertor 200 respectively, so that the second end of the first mating member 320 is fixed relative to the first support member 310 and the divertor 200. This facilitates the use of the first support member 310 to support the first mating member 320 and the divertor 200, ensuring the positional stability of the first mating member 320 and the divertor 200, and thus effectively supporting the outer side of the divertor 200 using the first support member 310.

[0038] It should be noted that the outer side of the divertor 200 refers to the part located inside the vacuum chamber 100 and close to the maintenance window 110, which is convenient for direct operation by humans or robotic arms.

[0039] Combination Figure 2 , Figure 3 and Figure 8 As shown, the second support assembly 400 is disposed between the inner side of the divertor 200 and the inner wall of the vacuum chamber 100, and includes a second support member 410 and a second mating member 420. The second support member 410 is fixedly connected to the inner wall of the vacuum chamber 100, and the second mating member 420 is fixedly connected to the inner side of the divertor 200. A first support platform 411 is provided on the second support member 410. In the initial position, the second mating member 420 is disposed on the first support platform 411. In the fixed position, the second mating member 420 is disengaged from the first support platform 411 and is in a limiting engagement with the second support member 410. By fixing the second support member 410 to the inner wall of the vacuum chamber 100, the vacuum chamber 100 supports the second support member 410, ensuring the positional stability of the second support member 410.

[0040] Meanwhile, by fixing the second mating part 420 to the inside of the divertor 200, the inside of the divertor 200 can be used to support the second mating part 420, ensuring the positional stability of the second mating part 420. By setting the first support platform 411 on the second support member 410, the difficulty of setting the second mating part 420 on the first support platform 411 in the initial position can be reduced, making it easier to effectively support the second mating part 420 using the first support platform 411, thereby effectively supporting the inside of the divertor 200 and ensuring the positional stability of the inside of the divertor 200.

[0041] Furthermore, when in a fixed position, by disengaging the second mating member 420 from the first support platform 411 and engaging it with the second support member 410 for limiting and fixing, the second mating member 420 and the second support member 410 can be fixed together, thereby fixing the inner side of the divertor 200 to the second support member 410. This allows the second support assembly 400 to effectively support the inner side of the divertor 200, further facilitating the stable support of the inner side of the divertor 200 by the vacuum chamber 100 and ensuring the positional stability of the inner side of the divertor 200.

[0042] It should be noted that the inner side of the divertor 200 refers to the part located inside and deep within the vacuum chamber 100, which cannot be directly operated from the maintenance window 110.

[0043] In summary, by utilizing the coordinated operation of the first support component 300 and the second support component 400, the support effect of the first support component 300 and the second support component 400 on the divertor 200 can be guaranteed, thereby improving the support effect of the vacuum chamber 100 on the divertor 200 and achieving the purpose of placing the divertor 200 in the vacuum chamber 100.

[0044] As can be seen from the above structure, the tokamak device 1000 of this embodiment of the invention, by placing the first support component 300 between the outer side of the divertor 200 and the inner wall of the vacuum chamber 100 and configuring it to include a first support member 310 and a first mating member 320, and by using the first mating member 320 to drive the divertor 200 to rotate, can reduce the installation difficulty of the outer side of the divertor 200 and ensure the support effect of the first support member 310 on the outer side of the divertor 200, thereby realizing the effective support of the outer side of the divertor 200 by the vacuum chamber 100.

[0045] Furthermore, by placing the second support assembly 400 between the inner side of the divertor 200 and the inner wall of the vacuum chamber 100 and configuring it to include the second support member 410 and the second mating member 420, the installation difficulty of the inner side of the divertor 200 can be reduced, and the support effect of the second support member 410 on the outer side of the divertor 200 can be guaranteed, thereby realizing the effective support of the inner side of the divertor 200 by the vacuum chamber 100.

[0046] Furthermore, by utilizing the coordinated operation of the first support component 300 and the second support component 400, the first support component 300 and the second support component 400 can effectively support the divertor 200, thereby improving the support effect of the vacuum chamber 100 on the divertor 200 and reducing the difficulty of installing the divertor 200 in the vacuum chamber 100.

[0047] Understandably, compared with the prior art, this application uses the first support component 300 and the second support component 400 to support the divertor 200, thereby improving the support effect of the vacuum chamber 100 on the divertor 200. At the same time, by using the first mating part 320 to drive the divertor 200 to rotate, the installation difficulty of the divertor 200 can be reduced.

[0048] In some embodiments, combined with Figure 2 and Figure 3 As shown, the second mating component 420 is provided with a plurality of first connecting holes 423, and the inner side of the divertor 200 is provided with a plurality of second connecting holes (not shown in the figure). The plurality of first connecting holes 423 and the plurality of second connecting holes are arranged in a one-to-one correspondence. A connector (not shown in the figure) passes through the first connecting holes 423 and the second connecting holes. This enables the second mating component 420 to be fixedly connected to the inner side of the divertor 200, while also reducing the installation difficulty of the second mating component 420 and the inner side of the divertor 200, and ensuring the reliability of the connection between the second mating component 420 and the inner side of the divertor 200.

[0049] In some embodiments, the connector is a bolt, screw, etc.

[0050] In a specific example, screws are used to pass through the first connecting hole 423 and the second connecting hole to fix the second mating part 420 to the inside of the divertor 200.

[0051] In the description of this invention, features defined as "first," "second," and "third" may explicitly or implicitly include one or more of these features, used to distinguish and describe features, without any order or emphasis.

[0052] In some embodiments, such as Figure 4As shown, the divertor 200 has a first mounting plate 210 and a second mounting plate 220 on its outer side. The first end of the first mating member 320 is rotatably connected to the first mounting plate 210, and in a fixed position, the second end of the first mating member 320 is fixedly connected to the second mounting plate 220. This allows the first end of the first mating member 320 to be rotatably connected to the divertor 200, while simultaneously ensuring that the second end of the first mating member 320 is fixedly connected to the divertor 200 in a fixed position.

[0053] Meanwhile, by providing a first mounting plate 210 and a second mounting plate 220 on the outside of the divertor 200, the first mounting plate 210 can reduce the difficulty of rotatably connecting the first end of the first mating member 320 to the divertor 200, and the second mounting plate 220 can reduce the difficulty of fixing the second end of the first mating member 320 to the divertor 200 in a fixed position.

[0054] In some embodiments, combined with Figures 9-13 As shown, the second end of the first mating component 320 is provided with a first mounting hole 321 and a second mounting hole 322 arranged sequentially. The first mounting hole 321 is used to realize the mating connection between the first mating component 320 and the second mounting plate 220, and the second mounting hole 322 is used to realize the mating connection between the first mating component 320 and the first support component 310. Specifically, by providing the first mounting hole 321, the difficulty of mating the first mating component 320 and the second mounting plate 220 can be reduced; by providing the second mounting hole 322, the difficulty of mating the first mating component 320 and the first support component 310 can be reduced, and the difficulty of disassembling the second end of the first mating component 320 from the first support component 310 can also be reduced.

[0055] In some embodiments, combined with Figure 4 , Figure 11 as well as Figures 14-16 As shown, the second mounting plate 220 has a first mating hole 221 and a second mating hole (not shown in the figure) arranged in sequence. The first mating hole 221 is located on the side of the second mating hole away from the first support member 310. In the initial position, the first mounting hole 321 mates with the first mating hole 221 to fix the first mating member 320. In the fixed position, the first mounting hole 321 mates with the second mating hole to fix the first mating member 320. In this way, a fixed connection can be achieved between the second mounting plate 220 and the first mating member 320 in both the initial and fixed positions.

[0056] In some embodiments, combined with Figure 6 , Figure 11 and Figure 16As shown, the first support member 310 is provided with a third mating hole 314 that mates with the second mounting hole 322. The third mating hole 314 can further reduce the difficulty of mating and connecting the first mating member 320 and the first support member 310.

[0057] In some embodiments, combined with Figure 4 , Figure 5 and Figure 11 As shown, the first mating component 320 has multiple first limiting plates 323 on its first end, and the first mounting plate 210 has multiple first limiting grooves 211. Each first limiting plate 323 is individually located within a first limiting groove 211, and the first fastener 500 passes through multiple first limiting plates 323 simultaneously. By having multiple first limiting plates 323 on the first end of the first mating component 320 and multiple first limiting grooves 211 on the first mounting plate 210, with each first limiting plate 323 individually located within a first limiting groove 211, the first limiting grooves 211 limit each first limiting plate 323, thereby increasing the connection strength between the first end of the first mating component 320 and the first mounting plate 210. This facilitates ensuring the reliability of the rotatable connection between the first end of the first mating component 320 and the first mounting plate 210.

[0058] Meanwhile, by using the first fastener 500 to simultaneously pass through multiple first limiting plates 323, the first end of the first mating part 320 is connected to the first mounting plate 210, thereby reducing the installation difficulty of the first end of the first mating part 320 and the first mounting plate 210.

[0059] In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0060] In some embodiments, the first fastener 500 is a pin or bolt, etc.

[0061] In a specific example, the first fastener 500 is formed as a pin, which is simultaneously inserted through multiple first limiting plates 323, ensuring the stability of the rotational connection between the first end of the first mating part 320 and the first mounting plate 210.

[0062] In some embodiments, combined with Figure 4 , Figure 5 and Figure 11As shown, a plurality of second limiting plates 324 are formed on the second end of the first mating member 320, and a second limiting groove 3241 is formed between two adjacent second limiting plates 324. A plurality of second mounting plates 220 are provided on the outer side of the divertor 200. Each second mounting plate 220 is individually disposed in a second limiting groove 3241 and can slide relative to the second limiting groove 3241. The second fastener 600 passes through the plurality of second limiting plates 324 and the plurality of second mounting plates 220. In this design, multiple second limiting plates 324 are formed on the second end of the first mating member 320, and a second limiting groove 3241 is formed between two adjacent second limiting plates 324. Multiple second mounting plates 220 are provided on the outer side of the divertor 200, and each second mounting plate 220 is individually disposed in a second limiting groove 3241 and can slide relative to the second limiting groove 3241. The second limiting groove 3241 can be used to slide and limit each second mounting plate 220, which can ensure the stability of the sliding of the second end of the first mating member 320 relative to the second limiting groove 3241.

[0063] Meanwhile, by using the second fastener 600 to simultaneously pass through multiple second limiting plates 324 and multiple second mounting plates 220, the connection strength between the second end of the first mating part 320 and the second mounting plate 220 can be guaranteed, reducing the connection difficulty between the multiple second limiting plates 324 and multiple second mounting plates 220, thereby reducing the installation difficulty of the second end of the first mating part 320 and the second mounting plate 220, and facilitating the fixed connection between the second end of the first mating part 320 and the second mounting plate 220 when in a fixed position.

[0064] In some embodiments, combined with Figure 6 and Figure 19 As shown, a second support platform 311 is formed on the first support member 310. In a fixed position, at least a portion of the second end of the first mating member 320 is disposed on the second support platform 311. The second support platform 311 is provided with a plurality of third limiting plates 3111, and a third limiting groove 3112 is formed between two adjacent third limiting plates 3111. Each second limiting plate 324 is individually disposed in a third limiting groove 3112. The third fastener 700 passes through the plurality of third limiting plates 3111 and the plurality of second limiting plates 324 simultaneously. In the fixed position, by disposing at least a portion of the second end of the first mating member 320 on the second support platform 311, the second support platform 311 can support the second end of the first mating member 320, ensuring the positional stability of the second end of the first mating member 320, thereby ensuring the positional stability of the first mating member 320.

[0065] Meanwhile, by providing multiple third limiting plates 3111 on the second support platform 311, and forming a third limiting groove 3112 between two adjacent third limiting plates 3111, and by individually setting each second limiting plate 324 in a third limiting groove 3112, the difficulty of ensuring the positioning of the second limiting plate 324 and the third limiting plate 3111 can be reduced, and the positioning accuracy of the second limiting plate 324 and the third limiting plate 3111 can be guaranteed.

[0066] Furthermore, by using the third fastener 700 to simultaneously pass through multiple third limiting plates 3111 and multiple second limiting plates 324, the third fastener 700 can reduce the difficulty of fixing multiple third limiting plates 3111 and multiple second limiting plates 324, ensure the connection strength of multiple third limiting plates 3111 and multiple second limiting plates 324, and thus facilitate fixing the second end of the first mating member 320 to the first support member 310.

[0067] In some embodiments, combined with Figure 4 , Figure 5 as well as Figures 9-19 As shown, a mounting space 325 is formed between the first mating member 320 and the divertor 200. The mounting space 325 is suitable for mounting a driving member (not shown). The first mating member 320 has a mating protrusion 326 on its side facing the mounting space 325. The output end of the driving member is adapted to contact the mating protrusion 326, and the driving member is used to drive the first mating member 320 to rotate towards the first support member 310. By forming the mounting space 325 between the first mating member 320 and the divertor 200, the installation difficulty of the driving member can be reduced.

[0068] Meanwhile, by providing a mating protrusion 326 on the side of the first mating member 320 facing the installation space 325, the output end of the driving member is adapted to contact the mating protrusion 326. The mating protrusion 326 can reduce the connection difficulty between the output end of the driving member and the first mating member 320, ensure the contact area between the output end of the driving member and the first mating member 320, and ensure that the driving member can always maintain an effective contact area with the first mating member 320 when driving the first mating member 320, so that the force of the driving member can drive the first mating member 320 to rotate toward the first support member 310.

[0069] Furthermore, by using a driving component to drive the first mating component 320 to rotate toward the first support component 310, the difficulty of rotating the first mating component 320 is reduced, thereby making it easier for the first mating component 320 to drive the divertor 200 to rotate.

[0070] In some embodiments, the driving component is a hydraulic mechanism, such as a hydraulic cylinder or a hydraulic motor.

[0071] In a specific example, the driving component is an electric jack, which applies a load to drive the first mating component 320 to rotate toward the first support component 310.

[0072] Wherein, the direction of the load is as follows Figure 13 and Figure 16 The direction of the dashed arrow shown.

[0073] In some embodiments, combined with Figure 3 , Figure 17 and Figure 18 As shown, the second support assembly 400 also includes a deformation buffer 430. In a fixed position, the deformation buffer 430 is disposed between the second support 410 and the second mating member 420 to provide buffering when the divertor 200 is under stress overload. This effectively reduces the vibration and impact impact of stress on the second mating member 420, effectively disperses stress, and thus avoids collision damage to the second mating member 420 due to excessive stress. This improves the structural stability of the second mating member 420, extends its service life, and facilitates ensuring the reliable connection between the second support 410 and the second mating member 420.

[0074] It should be noted that when plasma transiently impacts the divertor 200, or when there is an abnormal distribution of heat load, the divertor 200 will experience stress overload.

[0075] In some embodiments, the deformation buffer 430 may be made of wear-resistant tin bronze or other copper alloys, so that the deformation buffer 430 has a certain deformation buffering capacity, which facilitates buffering when the divertor 200 is overloaded.

[0076] In some embodiments, combined with Figure 3 , Figure 8 and Figure 10 As shown, a deformable buffer 430 is disposed on one of the second support 410 and the second mating member 420. The other of the second support 410 and the second mating member 420 has a receiving groove 412. The deformable buffer 430 protrudes towards the receiving groove 412 and is disposed within it. The protruding surface of the deformable buffer 430 is formed as a hemispherical surface, and the receiving groove 412 is formed as a hemispherical groove. By forming the protruding surface of the deformable buffer 430 as a hemispherical surface and the receiving groove 412 as a hemispherical groove, the mutual engagement of the deformable buffer 430 and the receiving groove 412 allows the hemispherical surface and the hemispherical groove to interlock, thereby constraining the radial offset of one of the second support 410 and the second mating member 420, ensuring coaxial alignment between the second support 410 and the second mating member 420, and thus improving the positioning and centering accuracy between the second support 410 and the second mating member 420.

[0077] It should be noted that the deformable buffer 430 is provided on one of the second support 410 and the second mating part 420, and the other of the second support 410 and the mating part 420 is provided with a receiving groove 412. This can be understood as follows: when the deformable buffer 430 is provided on the second support 410, the second mating part 420 is provided with a receiving groove 412; or, when the deformable buffer 430 is provided on the second mating part 420, the second support 410 is provided with a receiving groove 412.

[0078] In specific examples, combined Figure 3 , Figure 8 and Figure 10 As shown, the deformable buffer 430 is provided on the second mating part 420, and the second support 410 is provided with a receiving groove 412. The deformable buffer 430 and the receiving groove 412 can improve the accuracy of the installation and positioning of the second mating part 420 and the receiving groove 412.

[0079] In some embodiments, combined with Figure 8 , Figure 10 and Figure 18 As shown, the first support platform 411 is located near the bottom of the second support member 410, and the top of the second support member 410 is provided with a limiting plate 413. The limiting plate 413 is used to abut against the top wall of the second mating member 420 to limit the displacement of the second mating member 420. This achieves the limitation of the divertor 200, which on the one hand prevents the divertor 200 from moving too quickly during installation and sliding off the top of the second support member 410 from deviating from the set installation position, and on the other hand, during use after the divertor 200 is installed, it can also prevent the divertor 200 from slipping off the top of the second support member 410 due to the action of huge loads (such as plasma transient impacts), thus ensuring the installation stability of the divertor 200.

[0080] In some embodiments, combined with Figure 8 , Figure 10 and Figure 18 As shown, the limiting plate 413 has a limiting groove 4131 on the side facing the second mating member 420, and the top wall of the second mating member 420 forms a limiting protrusion 421, which can be limited and fitted in the limiting groove 4131. By utilizing the limiting fit of the limiting protrusion 421 and the limiting groove 4131, the limiting strength of the limiting plate 413 and the top wall of the second mating member 420 can be further guaranteed, and the limiting difficulty of the top wall of the second mating member 420 and the second mating member 420 can be reduced.

[0081] In some embodiments, combined with Figure 3 , Figure 8 , Figure 10 and Figure 18As shown, a first guide slope 411 is formed at the end of the first support platform 411 facing away from the divertor 200. A second guide slope 422 is provided on the second mating member 420 to mate with the first guide slope 4111. The first guide slope 4111 and the second guide slope 422 mate to guide the divertor 200 from its initial position to a fixed position. By utilizing the mate of the first guide slope 4111 and the second guide slope 422, the second guide slope 422 moves along the direction of the first guide slope 4111, which helps reduce the difficulty of switching the divertor 200 from its initial position to its fixed position, and also simplifies the subsequent positioning and limiting mating of the second mating member 420 and the second support member 410.

[0082] In some embodiments, combined with Figure 2 , Figure 7 and Figure 11 As shown, the first support assembly 300 also includes a third support member 330, which is fixedly connected to the inner wall of the vacuum chamber 100 and located below the first support member 310. In the initial position, the first mounting plate 210 is supported on the third support member 330. By fixing the third support member 330 to the inner wall of the vacuum chamber 100, the vacuum chamber 100 can support the third support member 330, ensuring the positional stability of the third support member 330.

[0083] Meanwhile, by setting the third support 330 below the first support 310, interference between the first support 310 and the third support 330 can be avoided. This makes it easier to support the first mounting plate 210 with the third support 330 in the initial position, thereby ensuring the positional stability of the first mounting plate 210 and thus ensuring the stability of the outer side of the divertor 200 during subsequent installation.

[0084] In some embodiments, the first support member 310, the second support member 410, and the third support member 330 all extend circumferentially along the vacuum chamber 100. It should be noted that the tokamak device 1000 has a circumferential structure, the vacuum chamber 100 is annular, and multiple divertors 200 are provided within the vacuum chamber 100. Therefore, each divertor 200 installed within the vacuum chamber 100 requires the use of the first support member 310, the second support member 410, and the third support member 330. By extending the first support member 310, the second support member 410, and the third support member 330 circumferentially along the vacuum chamber 100, the first support member 310, the second support member 410, and the third support member 330 are adapted to the annular vacuum chamber 100, facilitating full circumferential support of the multiple divertors 200 by the vacuum chamber 100.

[0085] In some embodiments, maintenance windows 110 include multiple maintenance windows 110 arranged in a ring around the vacuum chamber 100 at intervals. At least one maintenance window 110 is usually not provided with a third support member 330 to avoid the third support member 330 interfering with the divertor 200 being pushed into the vacuum chamber 100 along the maintenance window 110. The installation sequence of the divertor 200 corresponding to this maintenance window 110 is the last one. That is, all other divertors 200 are installed through this maintenance window 110 and moved to a specific position along the ring. After the installation is completed, the last divertor 200 can be installed directly in this maintenance window 110.

[0086] In some embodiments, combined with Figure 2 , Figure 6 , Figure 11 as well as Figure 19 As shown, the first support member 310 includes a first base 312 and a first guide rail 313. The first base 312 has a first part 3121 and a second part 3122 that are connected to each other. The first part 3121 is fixedly connected to the inner wall of the vacuum chamber 100. The second part 3122 is disposed on the side of the first part 3121 away from the inner wall of the vacuum chamber 100. The first guide rail 313 is detachably connected to the second part 3122. A second support platform 311 is formed on the first guide rail 313. In a fixed position, at least a portion of the second end of the first mating member 320 is disposed on the second support platform 311. By having the first base 312 have a first part 3121 and a second part 3122 that are connected to each other, the processing difficulty of the first base 312 can be reduced, and the second part 3122 can adjust its own surface flatness. This allows the first support 310 to be on the same circumferential horizontal line when it extends along the circumference of the vacuum chamber 100. This makes it easier to improve the accuracy of the installation position of the first guide rail 313, and thus make it easier to ensure the accuracy of the installation position of the divertor 200.

[0087] Meanwhile, by fixing the first part 3121 to the inner wall of the vacuum chamber 100, the vacuum chamber 100 can effectively support the first part 3121 and ensure the stability of the first part 3121.

[0088] Furthermore, by detachably connecting the first guide rail 313 to the second part 3122, the difficulty of installing and removing the first guide rail 313 can be reduced, making it easier to repair and replace the first guide rail 313.

[0089] In some embodiments, a first positioning protrusion (not shown in the figure) is provided on one of the inner wall of the vacuum chamber 100 and the first portion 3121, and a first positioning groove (not shown in the figure) is provided on the other. The first positioning protrusion and the first positioning groove cooperate to position the first portion 3121 on the inner wall of the vacuum chamber 100. The provision of a first positioning protrusion on one of the inner wall of the vacuum chamber 100 and a first positioning groove on the other means that the inner wall of the vacuum chamber 100 has a first positioning protrusion and the first portion 3121 has a first positioning groove, or vice versa. This arrangement ensures the ease of positioning the inner wall of the vacuum chamber 100 and the first portion 3121, and guarantees the reliability of their positioning.

[0090] In a specific example, the second part 3122, the second base 414, and the third base 331 are all fixed to the inner wall of the vacuum chamber 100 by welding.

[0091] In some embodiments, combined with Figure 2 , Figure 8 and Figure 10 As shown, the second support member 410 includes a second base 414 and a second guide rail 415. The second base 414 is fixedly connected to the inner wall of the vacuum chamber 100, and the second guide rail 415 is detachably connected to the second base 414. A first support platform 411 is formed on the second guide rail 415, and a second mating member 420 is disposed on the first support platform 411 and can slide along the second guide rail 415. By fixing the second base 414 to the inner wall of the vacuum chamber 100, the vacuum chamber 100 can effectively support the second base 414, ensuring the positional stability of the second base 414.

[0092] Meanwhile, by detachably connecting the second guide rail 415 to the second base 414, the difficulty of installing and removing the second guide rail 415 can be reduced, making it easier to repair and replace the second guide rail 415.

[0093] It should be noted that the second mating part 420 being located on the first support platform 411 and being able to slide along the second guide rail 415 means that the second mating part 420 slides toward the second guide rail 415 during installation, so as to facilitate the installation of the divertor 200 into the accurate position.

[0094] In some embodiments, a second positioning protrusion (not shown) is provided on one of the inner wall of the vacuum chamber 100 and the second base 414, and a second positioning groove (not shown) is provided on the other. The second positioning protrusion and the second positioning groove cooperate to position the second base 414 on the inner wall of the vacuum chamber 100. The provision of a second positioning protrusion on one of the inner wall of the vacuum chamber 100 and a second positioning groove on the other means that the inner wall of the vacuum chamber 100 has a second positioning protrusion and the second base 414 has a second positioning groove, or vice versa. This arrangement ensures the ease of positioning the inner wall of the vacuum chamber 100 and the second base 414, and guarantees the reliability of their positioning.

[0095] In some embodiments, combined with Figure 2 , Figure 7 and Figure 10 As shown, the third support member 330 includes a third base 331 and a third guide rail 332. The third base 331 is fixedly connected to the inner wall of the vacuum chamber 100, and the third guide rail 332 is detachably connected to the third base 331. The first mounting plate 210 is disposed on the third guide rail 332 and can slide along the third guide rail 332. By fixing the third base 331 to the inner wall of the vacuum chamber 100, the vacuum chamber 100 supports the third base 331, ensuring the positional stability of the third base 331.

[0096] Meanwhile, by detachably connecting the third guide rail 332 to the third base 331, the difficulty of installing and disassembling the third guide rail 332 can be reduced, making it easier to repair and replace the third guide rail 332.

[0097] It should be noted that the first mounting plate 210 is located on the third guide rail 332 and can slide along the third guide rail 332. This can be understood as the first mounting plate 210 being able to slide along the extension direction of the third guide rail 332, which facilitates the installation of the divertor 200 in the accurate position.

[0098] In some embodiments, a third positioning protrusion (not shown in the figure) is provided on one of the inner wall of the vacuum chamber 100 and the third base 331, and a third positioning groove (not shown in the figure) is provided on the other. The third positioning protrusion and the third positioning groove cooperate to position the third base 331 on the inner wall of the vacuum chamber 100. The provision of a third positioning protrusion on one of the inner wall of the vacuum chamber 100 and a third positioning groove on the other means that the inner wall of the vacuum chamber 100 has a third positioning protrusion and the third base 331 has a third positioning groove, or vice versa. This arrangement ensures the ease of positioning the inner wall of the vacuum chamber 100 and the third base 331, and guarantees the reliability of their positioning.

[0099] Of course, in some other embodiments, the first part 3121, the second base 414 and the third base 331 can also be fixed to the inner wall of the vacuum chamber 100 by welding.

[0100] The following describes the installation method of the tokamak device 1000 according to an embodiment of the present invention with reference to the accompanying drawings.

[0101] like Figure 20 As shown, an installation method for a tokamak device 1000 according to an embodiment of the present invention includes: S1. Install the first support member 310 and the second support member 410 on the inner wall of the vacuum chamber 100 respectively.

[0102] In the above steps, the vacuum chamber 100 stably supports the first support member 310 and the second support member 410, ensuring the positional stability of the first support member 310 and the second support member 410.

[0103] S2. Install a first mating part 320 on the outside of the divertor 200 and a second mating part 420 on the inside of the divertor 200.

[0104] In the above steps, the first mating member 320 can be effectively supported by the outside of the divertor 200, and the divertor 200 can be effectively supported by the second mating member 420, which facilitates the subsequent setting of the first mating member 320 and the first support member 310, as well as the mating of the second support member 410 and the second mating member 420.

[0105] In a specific example, the first mating part 320 can be connected to the outside of the divertor 200 using pins, bolts, etc., while the second mating part 420 can be fixed to the inside of the divertor 200 using pins, bolts, etc.

[0106] S3. Move the divertor 200 into the vacuum chamber 100 and place the second mating part 420 on the first support platform 411 (in conjunction with...) Figure 9 , Figure 10 and Figure 11 (As shown).

[0107] In the above steps, the outer side of the divertor 200 can be limited to the first support platform 411, so as to achieve the purpose of using the first support platform 411 to support the divertor 200 and achieve the initial positioning of the divertor 200.

[0108] In a specific example, a robotic arm can be used to deliver the divertor 200 into the vacuum chamber 100 through the maintenance window 110, and the second mating component 420 can be placed on the first support platform 411.

[0109] S4. Control the first mating component 320 to rotate so as to drive the divertor 200 to move, so that the second mating component 420 can move relative to the second support component 410 and engage with the second support component 410 in a limited position (combination). Figures 12-19 (As shown).

[0110] In other words, when the second mating part 420 is placed on the first support platform 411, the first mating part 320 is controlled to rotate, thereby driving the divertor 200 to move. After the divertor 200 moves, the second mating part 420 can move relative to the second support part 410 and be limited to the second support part 410, so as to limit the second mating part 420 on the second support part 410, thereby achieving the limited engagement between the inner side of the divertor 200 and the second support part 410, which facilitates the fixation of the divertor 200.

[0111] S5. Fix the second end of the first mating part 320 to the divertor 200.

[0112] In other words, when the first mating part 320 rotates to drive the divertor 200 to move and the inner side of the divertor 200 is limited and engaged with the second support part 410, the second end of the first mating part 320 is fixedly connected to the divertor 200, so as to realize the fixed connection between the outer side of the divertor 200 and the second end of the first mating part 320. This facilitates the fixed connection between the outer side of the divertor 200 and the first support part 310, makes it easier to fix the divertor 200, and improves the positional stability of the divertor 200.

[0113] The tokamak device 1000 is the aforementioned tokamak device 1000, and the specific structure of the tokamak device 1000 will not be described in detail here.

[0114] As can be seen from the above method, the installation method of the tokamak device 1000 in this embodiment of the invention adopts an internal and external support form (first support member 310 and second support member 410). The key point is that the first mating member 320 is rotatably installed on the outside of the divertor 200. The rotation of the first mating member 320 can drive the divertor 200 to move, so that the second mating member 420 can move relative to the second support member 410 and be limited to the second support member 410. This achieves the purpose of supporting the divertor 200 by the cooperation of the first support member 310 and the second support member 410, thereby improving the support effect of the vacuum chamber 100 on the divertor 200. It is also easy to implement in a non-window position, reducing the difficulty of supporting the divertor 200.

[0115] In some embodiments, such as Figure 20 As shown, controlling the rotation of the first mating component 320 to drive the divertor 200 to move includes the following steps: S41. Control the second end of the first mating member 320 to rotate toward the first support member 310, and make the second end of the first mating member 320 engage with the first support member 310 (connection). Figure 12 and Figure 13 (As shown).

[0116] In other words, when the second mating part 420 is placed on the first support platform 411, the second end of the first mating part 320 is controlled to rotate toward the first support part 310, and the second end of the first mating part 320 is engaged with the first support part 310 to achieve the initial movement of the second end of the first mating part 320 onto the first support part 310.

[0117] In a specific example, before controlling the second end of the first mating member 320 to rotate toward the first support member 310, the second fastener 600 is pulled out from the first mating hole 221 and the first mounting hole 321. Then, an electric jack is used to apply a load toward the first mating member 320, causing the second end of the first mating member 320 to rotate toward the first support member 310 until the second end of the first mating member 320 is in a stop-fitting engagement with the first support member 310. At this time, the centers of the first mounting hole 321 and the second mating hole are opposite each other, and the centers of the second mounting hole 322 and the third mating hole 314 are opposite each other.

[0118] S42. The second end of the first mating member 320 is fixedly connected to the first support member 310.

[0119] In other words, when the second end of the first mating member 320 is engaged with the first support member 310, the second end of the first mating member 320 is fixedly connected to the first support member 310 so that the second end of the first mating member 320 is in a relative position with the first support member 310, thereby fixing the second end of the first mating member 320 onto the first support member 310.

[0120] In a specific example, by passing the second fastener 600 through the first mounting hole 321 and the second mating hole, and by passing the third fastener 700 through the second mounting hole 322 and the third mating hole 314, the second end of the first mating member 320 is fixedly connected to the divertor 200 and the first support member 310, respectively.

[0121] S43. Continue to rotate the second end of the first mating part 320 to use the first end of the first mating part 320 to drive the divertor 200 to move (in conjunction with...) Figures 14-19 (As shown).

[0122] In other words, after the second end of the first mating member 320 is fixedly connected to the divertor 200 and the first support member 310 respectively, if the second end of the first mating member 320 continues to rotate, since the second end of the first mating member 320 is fixed by the divertor 200 and the first support member 310, the first end of the first mating member 320 can be rotated, so as to realize that the first end of the first mating member 320 can drive the divertor 200 to move. At this time, the divertor 200 can drive the second mating member 420 to move relative to the second support member 410, so that the second mating member 420 and the second support member 410 are in a limited fit, thus realizing the limited fit between the divertor 200 and the second support member 410.

[0123] It should be noted that after the second end of the first mating member 320 is fixedly connected to the divertor 200 and the first support member 310 respectively, the second end of the first mating member 320 is fixed by the limiting of the second mounting plate 220 of the divertor 200 and the first support member 310. That is to say, when the driving member continues to apply a load toward the first support member 310 to the mating protrusion 326 of the first mating member 320, the first mating member 320 has a counteracting effect on the divertor 200 and the first mounting plate 210. When force is applied, the reaction force acts on the second mating member 420 in the direction away from the first support member 310, so that the second guide slope 422 can move along the first guide slope 4111. As the driving member continuously applies a load to the mating protrusion 326, this reaction force continues to push the second mating member 420 to move in the direction away from the first support member 310 until the limiting fit between the deformation buffer member 430 and the receiving groove 412 and the limiting fit between the limiting groove 4131 and the limiting protrusion 421 are completed in sequence.

[0124] In some embodiments, combined with Figure 2 , Figures 9-11 as well as Figure 20As shown, the first support assembly 300 also includes a third support member 330, which is fixedly connected to the inner wall of the vacuum chamber 100 and located below the first support member 310. The first support member 310, the second support member 410, and the third support member 330 all extend circumferentially along the vacuum chamber 100. After moving the divertor 200 into the vacuum chamber 100 and placing the second mating member 420 on the first support platform 411, the following steps are also included: S04. Move the divertor 200 circumferentially along the vacuum chamber 100 so that at least a portion of the divertor 200 is supported on the third support 330.

[0125] In the above steps, by moving the divertor 200 circumferentially along the vacuum chamber 100, the divertor 200 can be moved onto the preset third support 330, thereby facilitating the effective support of the divertor 200 by the third support 330.

[0126] In some embodiments, the unmanned installation of the tokamak device 1000 can be achieved by using a robotic arm to move the divertor 200 into the vacuum chamber 100, using a robotic arm to install the drive unit into the installation space 325, using a robotic arm to install the first fastener 500 and the third fastener 700, and using a robotic arm to disassemble and install the second fastener 600.
