Description

Technical Field

[0001] This invention relates to the field of nuclear fusion technology, and in particular to an assembly method and assembly tooling for a nuclear fusion device. Background Technology

[0002] Related technologies indicate that solving the energy problem is one of the most pressing issues facing all countries today. Nuclear fusion energy is a new type of clean energy, and controlled nuclear fusion is an important area that countries around the world are actively researching and exploring. Controlled nuclear fusion utilizes a fusion device called a tokamak to magnetically confine high-temperature plasma, causing the plasma to undergo a fusion reaction in a vacuum chamber, releasing enormous energy, which is then converted and ultimately used by humanity. The fusion device consists of thousands of components, with its core components being a superconducting magnet system and a vacuum chamber system. The superconducting magnet system includes a central solenoid magnet, a toroidal field magnet, and a poloidal field magnet. The central solenoid magnet provides the volt-seconds required to generate, establish, and maintain the plasma current through current changes. The poloidal field magnet generates a poloidal magnetic field to control the shape and positional balance of the plasma cross-section. The toroidal field magnet generates a toroidal magnetic field to ensure the macroscopic overall stability of the plasma. The toroidal magnetic field and the poloidal magnetic field generated by the plasma current are used to confine the plasma. The vacuum chamber system provides a clean, ultra-high vacuum environment for the stable operation of the plasma and reduces the nuclear thermal deposition of neutrons produced by fusion on the superconducting magnet and environmental pollution. The gap between the vacuum chamber and the toroidal field magnet is extremely narrow, and the ring-shaped installation of the vacuum chamber sector and the toroidal field magnet is a crucial part of the construction of the fusion device.

[0003] The production cycle of vacuum chamber sectors and toroidal field magnets is relatively long. During the assembly of nuclear fusion devices, the delivery time of vacuum chamber sectors and toroidal field magnets is continuous and the synchronization of delivery is difficult to control. In the existing assembly method, the vacuum chamber sectors and toroidal field magnets are first pre-assembled into standard sector components in the pre-assembly hall outside the main unit hall, and then the whole assembly is hoisted. This installation method is very strict on the delivery time of each component. All sub-components in the standard sector must arrive and be pre-assembled before the main unit can be assembled. The assembly cycle is long and the efficiency is low. Summary of the Invention

[0044] Embodiments of the present invention are described in detail below, examples of which are illustrated 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 intended to explain the present invention, and should not be construed as limiting the present invention.

[0045] The following is for reference. Figures 1-13 A method for assembling a nuclear fusion device according to an embodiment of the first aspect of the present invention is described.

[0046] like Figure 1 , Figure 3 , Figure 11 and Figure 12 As shown, according to the assembly method of a nuclear fusion device according to a first aspect embodiment of the present invention, the nuclear fusion device includes a vacuum chamber and a toroidal field magnet. The vacuum chamber is formed by splicing multiple vacuum chamber sectors in the circumferential direction. The multiple vacuum chamber sectors include at least one first sector 10 and at least one second sector 11. The toroidal field magnet is formed by splicing multiple magnetic field units in the circumferential direction. The magnetic field unit includes at least one first magnet 12 and at least one second magnet 13. The first sector 10 is adapted to be fitted with the first magnet 12, and the second sector 11 is adapted to be fitted with the second magnet 13.

[0047] Assembly methods include:

[0048] S1. Outside the host hall 100, the first sector 10 and the first magnet 12 are assembled to form a standard sector 14. The standard sector 14 is moved to the host hall 100. The second sector 11 and the second magnet 13 are assembled in the host hall 100.

[0049] S2. In the main hall 100, multiple vacuum chamber sectors are spliced ​​together in the circumferential direction, and multiple magnetic field units are spliced ​​together in the circumferential direction.

[0050] The main hall 100 is the site where the nuclear fusion device is assembled and subsequent nuclear fusion work is carried out. During the assembly process, the second sector 11 can be hoisted into the main hall 100 first, or the standard sector 14 can be hoisted into the main hall 100 first. It should be noted that when the standard sector 14 is hoisted into the main hall 100 first, at least one end of the second sector 11 in the circumferential direction needs to be left with operating space for the second magnet 13.

[0051] In actual production, the manufacturing process of the magnetic field unit is relatively complex and the production time is long. The vacuum chamber sector will arrive first. During the assembly process, the second sector 11 can be hoisted into the host hall 100 first. The second magnet 13 and the second sector 11 are assembled in the host hall 100. At the same time, the first magnet 12 and the first sector 10 are assembled outside the host hall 100 to form the standard sector 14. The standard sector 14 is then hoisted into the host hall 100. After the subsequent magnetic field units arrive, the second sector 11 and the second magnet 13, which were not fully matched in the previous process, can be assembled in the main unit hall 100. Simultaneously, outside the main unit hall 100, the first sector 10 and the first magnet 12, which were also not fully matched in the previous process, can be assembled to form a standard sector 14. The standard sector 14 is then hoisted into the main unit hall 100. Then, in the main unit hall 100, multiple vacuum chamber sectors and multiple magnetic field units are assembled circumferentially to complete the loop-connection operation of the vacuum chambers and the circumferential magnets. This allows for efficient use of the arrival time of the vacuum chamber sectors and magnetic field units.

[0052] According to the assembly method of the nuclear fusion device of the first aspect of the present invention, during the assembly process of the nuclear fusion device, the first sector 10 and the first magnet 12 are assembled outside the main hall 100 to form a standard sector 14, and the second sector 11 and the second magnet 13 are assembled inside the main hall 100. These processes can be carried out simultaneously, thereby making reasonable use of the arrival time of the vacuum chamber sector and the magnetic field unit and improving the assembly efficiency of the nuclear fusion device.

[0053] In some embodiments of the present invention, there are multiple first sectors 10 and second sectors 11. For example, there can be two, three, four, or six first sectors 10, and two, three, four, or six second sectors 11. The second sectors 11 and the standard sector 14 are arranged alternately in the circumferential direction of the vacuum chamber. In this way, during the assembly process, the second sector 11 is first hoisted into the main unit hall 100 and the second magnet 13 is installed on the second sector 11. The second sector 11 has more operating space at both ends in the circumferential direction, which can reduce the assembly difficulty and further improve the assembly efficiency.

[0054] In some embodiments of the present invention, such as Figure 2 , Figure 11 , Figure 12 and Figure 13 As shown, step S1 includes:

[0055] S11. Move multiple second sectors 11 to the main unit hall 100 and arrange the multiple second sectors 11 at intervals in the circumferential direction of the vacuum chamber sector. Outside the main unit hall 100, fit the first sector 10 and the first magnet 12 together to form a standard sector 14.

[0056] Specifically, firstly, a first lifting device 30 is installed on the support assembly. The two ends of the first lifting beam 31 are supported on the support beam 22 and the support column 21, respectively. Multiple first lifting devices 30 are arranged at intervals around the support column 21. Then, the balance beam assembly 60 is connected to one of the first lifting devices 30. The first lifting device 30 is used to move the second sector 11 to the main hall 100 and place the first lifting device 30 in its previous position. The first lifting component 321 on the first tie rod 32 is connected to the second sector 11. Then, the position of the first tie rod 32 on the first lifting beam 31 is adjusted to adjust the position of the second sector 11 and complete the installation of the second sector 11 in the main hall 100. The above steps are repeated in sequence. At the same time, the first sector 10 and the first magnet 12 are assembled outside the main hall 100 using a third lifting device 80.

[0057] The arrangement of multiple second sectors 11 in the circumferential direction of the vacuum chamber sector allows multiple first lifting devices 30 to be arranged in the circumferential direction of the support column 21, thereby improving the stability and reliability of the first lifting devices 30 on the support assembly.

[0058] Preferably, there are four second sectors 11, which are evenly and spaced apart in the circumference of the vacuum chamber sector.

[0059] S12. Mount the second magnet 13 onto the second sector 11.

[0060] First, the second magnet 13 is hoisted to the main hall 100 using a hoisting device via a balance beam assembly 60 and a second lifting device 40. One end of the second hoisting beam 41 is supported on the support column 21, and the other end is supported on the circular track 20 via a first roller 412. Specifically, the hoisting device is connected to the balance beam 61, the third tie rod 63 is connected to the second hoisting beam 41, and the second tie rod 42 on the second lifting device 40 is connected to the second magnet 13. During the assembly process, the roller drive 411 drives the first roller 412 at one end of the second hoisting beam 41 to rotate on the circular track 20, causing the second hoisting beam 41 to rotate around the support column 21 with the second magnet 13, thereby realizing the adjustment of the position of the second magnet 13 and its assembly on the second sector 11.

[0061] S13. Move the standard sector 14 between two adjacent second sectors 11.

[0062] Specifically, a lifting device is used to lift the standard sector 14 between two adjacent second sectors 11 via a balance beam assembly 60 and a third lifting device 80. The two ends of the third lifting beam 81 are respectively mounted on the support column 21 and the support beam 22. The lifting device is connected to the balance beam 61, the third tie rod 63 is connected to the third lifting beam 81, the sector tie rod 82 is connected to the first sector 10 in the standard sector 14 via a sector lifting component 821, and the magnet tie rod 83 is connected to the first magnet 12 in the standard sector 14 via a magnet lifting component 831.

[0063] During the splicing process of standard sector 14 with the two adjacent second sectors 11 and the second magnet 13, the position of the first sector 10 can be adjusted by adjusting the position of the sector tie rod 82 on the third hoisting beam 81, and the position of the first magnet 12 can be adjusted by the magnet adjustment assembly. Thus, the splicing of the first sector 10 and the adjacent second sector 11 in standard sector 14, and the splicing of the first magnet 12 and the adjacent second magnet 13 in standard sector 14 are realized.

[0064] This could be done by first assembling all the second sectors 11 and the second magnets 13, and then moving the standard sector 14 sequentially between two adjacent second sectors 11.

[0065] Alternatively, after completing the assembly of two adjacent second sectors 11 with their corresponding second magnets 13, the standard sector 14 can be moved sequentially between the two second sectors 11, and then the above operation can be repeated.

[0066] The following is for reference. Figures 1-13 The assembly tooling for a nuclear fusion device according to a second aspect of the present invention is described.

[0067] According to a second aspect of the present invention, an assembly fixture for a nuclear fusion device is applied to the assembly method for a nuclear fusion device according to a first aspect of the present invention. The assembly fixture includes a support assembly, a first lifting device 30, a second lifting device 40, and a third lifting device 80.

[0068] Specifically, the support assembly is arranged in the main hall 100. The first lifting device 30 is adapted to be supported on the support assembly and is used to lift the second sector 11 and the standard sector 14. The second lifting device 40 is adapted to be supported on the support assembly and is used to lift the second magnet 13. The third lifting device 80 is adapted to be supported on the support assembly and is used to lift the standard sector 14.

[0069] The assembly fixture for a nuclear fusion device according to a second aspect of the present invention can realize the assembly method according to the first aspect of the present invention, thereby improving the assembly efficiency of the nuclear fusion device.

[0070] In some embodiments of the present invention, such as Figure 3 and Figure 11 As shown, the support assembly includes: a ring track 20, a support column 21, and a support beam 22.

[0071] Specifically, the circular track 20 is fixed to the main hall 100, the support column 21 is supported on the ground and located inside the circular track 20, the support beam 22 is fixed to the circular track 20, and / or the main hall 100.

[0072] In other words, the support beam 22 can be fixed on the circular track 20, or it can be fixed on the main hall 100, or it can be fixed on both the circular track 20 and the main hall 100.

[0073] By setting up a circular track 20, support columns 21 and support beams 22, sufficient support positions can be provided within the main hall 100, thereby enabling the assembly of the nuclear fusion device.

[0074] In some embodiments of the present invention, such as Figure 4 , Figure 5 and Figure 12 As shown, the first lifting device 30 includes: a first lifting beam 31 and a first tie rod 32.

[0075] Specifically, the two ends of the first lifting beam 31 are adapted to be erected on the support beam 22 and the support column 21 respectively. One end of the first tie rod 32 is connected to the first lifting beam 31, and the other end of the first tie rod 32 is provided with a first lifting component 321. The first lifting component 321 is adapted to be connected to the second sector 11. The first tie rod 32 is movable relative to the first lifting beam 31 in the vertical direction and in the length and width directions of the first lifting beam 31.

[0076] Preferably, the first hoisting beam 31 corresponding to the standard sector 14 is also provided with a personnel passage 70 and a guardrail 71, which facilitates the installation of the standard sector 14.

[0077] During the assembly process, the position of the second sector 11 can be adjusted by adjusting the position of the first tie rod 32 relative to the first lifting beam 31 in the vertical direction and in the length and width direction of the first lifting beam 31, thereby completing the installation of the second sector 11.

[0078] Preferably, the first lifting beam 31 is provided with a first housing 33 and a first hydraulic component 34. The first housing 33 is provided with a first rotating shaft 331. The first rotating shaft 331 is movably disposed in the first housing 33 in the vertical direction via a first slider 332. One end of the first pull rod 32 is connected to the first rotating shaft 331 via a U-bolt. The first hydraulic component 34 has a first radial cylinder 341, a first circumferential cylinder 342, and a first vertical cylinder 343. The first vertical cylinder 343 is connected to the first rotating shaft 331 to drive the first rotating shaft 331 to move up and down in the first housing 33 via the first slider 332. The first radial cylinder 341 and the first circumferential cylinder 342 are both connected to the first housing 33 to drive the first housing 33 to move along the length and width directions of the first lifting beam 31, respectively. Thus, the first pull rod 32 can be automatically moved relative to the first lifting beam 31 in the vertical direction and in the length and width directions of the first lifting beam 31.

[0079] In some embodiments of the present invention, such as Figure 6 and Figure 7 As shown, the second lifting device 40 includes: a second lifting beam 41 and a second tie rod 42.

[0080] Specifically, one end of the second lifting beam 41 is adapted to be rotatably connected to the support column 21, and the other end of the second lifting beam 41 is adapted to be movably supported on the annular track 20. One end of the second tie rod 42 is connected to the second lifting beam 41, and the other end of the second tie rod 42 is provided with a second lifting component 421. The second lifting component 421 is adapted to be connected to the second magnet 13. The second tie rod 42 is movable relative to the second lifting beam 41 in the vertical direction and in the length and width directions of the second lifting beam 41.

[0081] During the assembly process, the second hoisting beam 41 rotates around the support column 21, and can drive the second magnet 13 to rotate on the second sector 11 through the second tie rod 42, thereby realizing the assembly of the second magnet 13 and the second sector 11.

[0082] Preferably, the second lifting beam 41 is provided with a second housing 43 and a second hydraulic component 44. The second housing 43 is provided with a second rotating shaft 431. The second rotating shaft 431 is movably disposed in the second housing 43 in the vertical direction via a second slider 432. One end of the second tie rod 42 is connected to the second rotating shaft 431 via a U-bolt. The second hydraulic component 44 has a second radial cylinder 441, a second circumferential cylinder 442 and a second vertical cylinder 443. The second vertical cylinder 443 is connected to the second rotating shaft 431 to drive the second rotating shaft 431 to move up and down in the second housing 43 via the second slider 432. The second radial cylinder 441 and the second circumferential cylinder 442 are both connected to the second housing 43 to drive the second housing 43 to move along the length and width directions of the second lifting beam 41 on the second lifting beam 41, respectively. Thus, the second tie rod 42 can be automatically moved relative to the second lifting beam 41 in the vertical direction and in the length and width directions of the second lifting beam 41.

[0083] The second hoisting beam 41 is equipped with a personnel passage 70 and a guardrail 71, which facilitates the assembly of the second magnet 13 and the second sector 11.

[0084] In some embodiments of the present invention, such as Figure 6 As shown, the other end of the second lifting beam 41 is provided with a roller drive component 411 and a first roller 412. The roller drive component 411 is connected to the first roller 412 to drive the first roller 412 to rotate. The other end of the second lifting beam 41 is movably mounted on the annular track 20 via the first roller 412. During the assembly of the second magnet 13 and the second sector 11, the roller drive component 411 drives the first roller 412 to rotate, allowing the second lifting beam 41 to rotate around the support column 21, thereby driving the second magnet 13 to rotate on the second sector 11. Thus, the assembly of the second magnet 13 and the second sector 11 can be achieved, and the assembly difficulty can be reduced.

[0085] In some embodiments of the present invention, such as Figures 11-13 As shown, the third lifting device 80 includes: a third lifting beam 81, a sector tie rod 82, and a magnet tie rod 83.

[0086] Specifically, the two ends of the third hoisting beam 81 are adapted to be respectively mounted on the support beam 22 and the support column 21. One end of the sector tie rod 82 is connected to the third hoisting beam 81, and the other end of the sector tie rod 82 is provided with a sector hoisting component 821. The sector hoisting component 821 is adapted to be connected to the first sector 10 in the standard sector 14. The sector tie rod 82 is movable relative to the third hoisting beam 81 in the vertical direction and in the length and width direction of the third hoisting beam 81. One end of the magnet tie rod 83 is connected to the third hoisting beam 81, and the other end of the magnet tie rod 83 is provided with a magnet hoisting component 831. The magnet hoisting component 831 is adapted to be connected to the first magnet 12 in the standard sector 14.

[0087] During the assembly process, the position of the first sector 10 in the standard sector 14 can be adjusted by adjusting the position of the sector tie rod 82 relative to the third lifting beam 81 in the vertical direction and in the length and width direction of the third lifting beam 81, thereby completing the installation of the standard sector 14.

[0088] Preferably, the third lifting beam 81 is provided with a third box body 84 and a third hydraulic component 85. The third housing 84 contains a third rotating shaft 841, which is movably mounted in the third housing 84 in the vertical direction via a third slider 842. One end of the sector tie rod 82 is connected to the third rotating shaft 841 via a U-bolt. The third hydraulic component 85 includes a third radial cylinder 851, a third circumferential cylinder 852, and a third vertical cylinder 853. The third vertical cylinder 853 is connected to the third rotating shaft 841 to drive the third rotating shaft 841 to move vertically within the third housing 84 via the third slider 842. The third radial cylinder 851 and the third circumferential cylinder 852 are both connected to the third housing 84 to drive the third housing 84 to move along the length and width of the third lifting beam 81 on the third lifting beam, respectively. Thus, the sector tie rod 82 can move automatically relative to the third lifting beam 81 in the vertical direction and in the length and width direction of the third lifting beam 81.

[0089] In some embodiments of the present invention, such as Figure 9 and Figure 10 As shown, the assembly fixture also includes a magnet adjustment assembly, which includes multiple adjustment components 50. For example, there may be two, three, or four adjustment components 50. Each adjustment component 50 includes a support portion 51 and an adjustment beam 52. The adjustment beam 52 is disposed on the support portion 51. The adjustment beam 52 is movable relative to the support portion 51 in the vertical direction, the radial direction, and the circumferential direction of the second magnet 13. The adjustment components 50 are adapted to be supported on the lower side of the first magnet 12 via the adjustment beam 52. The multiple adjustment components 50 are arranged at intervals in the radial direction of the first magnet 12.

[0090] During the splicing process of standard sector 14 and adjacent second sector 11 and second magnet 13 in the main hall 100, the adjustment beam 52 is supported below the first magnet 12. By moving the adjustment beam 52 along the vertical direction, the radial direction and the circumferential direction of the second magnet 13 on the support part 51, the position of the first magnet 12 can be adjusted, thereby reducing the splicing difficulty.

[0091] Preferably, the support part 51 is provided with a fourth hydraulic component 53, which has a fourth radial cylinder 531, a fourth circumferential cylinder 532 and a fourth vertical cylinder 533. The fourth radial cylinder 531, the fourth circumferential cylinder 532 and the fourth vertical cylinder 533 respectively drive the adjustment beam 52 to move in the vertical direction, the radial direction and the circumferential direction of the first magnet 12, thereby realizing the automatic movement of the support beam 22 on the support part 51.

[0092] In some embodiments of the present invention, such as Figure 10 As shown, the plurality of adjustment components 50 include a plurality of first adjustment components 54. Each first adjustment component 54 includes a first support portion 541 and a first adjustment beam 542. The magnet adjustment assembly also includes a movable beam 55. The first support portions 541 of the plurality of first adjustment components 54 are disposed on the movable beam 55. A second roller 551 is provided on the lower side of the movable beam 55.

[0093] During the assembly of standard sector 14 and adjacent second sector 11 and second magnet 13 in the main unit hall 100, the moving beam 55 and multiple first adjustment components 54 on the moving beam 55 support the first magnet 12 below the radial outer side of the first magnet 12. The multiple first adjustment beams 542 are structurally adapted to the first magnet 12. By setting the moving beam 55 and setting the second roller 551 on the lower side of the moving beam 55, it is easy to move the first adjustment components 54 during the assembly process, thereby further reducing the assembly difficulty.

[0094] Preferably, a fifth hydraulic component 552 is provided on the lower side of the moving beam 55. The fifth hydraulic component 552 is used to drive the support beam 22 to move in the vertical direction. In this way, when the moving beam 55 moves the radially outer side of the first magnet 12 to near the assembly position, the fifth hydraulic component 552 can be used to lift the moving beam 55, so that the second roller 551 does not contact the ground, thereby making the first magnet 12 more stable. Then, by adjusting the relative position of the first adjusting beam 542 and the first support part 541, the position and angle of the first magnet 12 on the first sector 10 can be finely adjusted.

[0095] In some embodiments of the present invention, such as Figure 8 and Figure 12 As shown, the assembly fixture also includes: a balance beam assembly 60, which includes a balance beam 61, a cable tray crossbeam 62, and a third tie rod 63. One end of the third tie rod 63 is connected to the cable tray crossbeam 62, and the other end of the third tie rod 63 is adapted to be connected to a first lifting device 30 or a second lifting device 40. The balance beam 61 and the cable tray crossbeam 62 extend in two intersecting directions. The balance beam 61 is movably mounted on the cable tray crossbeam 62 along the length and width directions of the cable tray crossbeam 62. The balance beam 61 is provided with a lifting lug 611, which is adapted to be connected to a lifting device.

[0096] During the hoisting process, by adjusting the relative positions of the balance beam 61 and the bridge beam 62, the relative position of the center of the hoisted object and the lifting lug 611 can be adjusted, thereby improving the stability during the hoisting process.

[0097] Preferably, the balance beam 61 is provided with two sixth hydraulic components 613, which drive the balance beam 61 to move in the length and width directions of the cable tray crossbeam 62, respectively. Thus, the balance beam 61 can move automatically relative to the cable tray crossbeam 62.

[0098] The balance beam 61 is provided with a first limiting block 612, which is used to limit the displacement path of the balance beam 61 in the width direction of the cable tray crossbeam 62. The cable tray crossbeam 62 is provided with a second limiting block 621, which is used to limit the displacement path of the balance beam 61 in the length direction of the cable tray crossbeam 62.
