Description

Technical Field

[0001] The invention relates to the technical field of nuclear fusion, in particular to an assembly method and an assembly tool for a toroidal field superconducting magnet of a nuclear fusion device. Background Art

[0002] As a new type of efficient and clean energy, nuclear fusion is widely regarded as the ultimate solution to human energy problems. Therefore, controlled nuclear fusion is an important field that countries around the world are actively researching and exploring. Controlled nuclear fusion uses a fusion device called tokamak to magnetically confine high-temperature plasma, causing the plasma to undergo a fusion reaction in a vacuum chamber, releasing huge amounts of energy, which is then converted into energy for human use.

[0003] The main engine of the tokamak device is composed of eight main engine sectors. Each main engine sector assembly includes components such as the vacuum chamber sector, the vacuum chamber cold shield sector and the toroidal field magnet. During the assembly of the main engine sectors, the toroidal field magnet moves along a circular track and is mounted on the outside of the vacuum chamber and the cold shield sector. Since the assembly gap between the toroidal field magnet and the vacuum chamber cold shield sector is small, the toroidal field magnet needs to adjust its position and posture multiple times during the assembly process to avoid collision interference.

[0004] In the prior art, when adjusting the toroidal field superconducting magnet, the position adjustment of three translational degrees of freedom can be achieved, but the three rotational degrees of freedom of the magnet cannot be adjusted. For the super-large toroidal field superconducting magnet in the nuclear fusion device, the assembly position accuracy of each point has extremely high technical requirements. Therefore, the assembly requirements of the magnet cannot be fully met only by adjusting the position of three translational degrees of freedom. The magnet assembly has poor accuracy and low efficiency, and there is a risk that the superconducting magnet cannot be installed or there is collision interference, which cannot meet the assembly requirements of the main sector of the fusion reactor.

[0054] The support frame 2 is disposed on the support frame 1. The support frame 2 is used to support the toroidal field superconducting magnet 200.

The driving device is connected to the support frame 1, and is used to drive the support frame 2 to rotate relative to the support frame 1 around the first axis, the second axis and / or the third axis.

[0055] The first direction, the second direction and the third direction are perpendicular to each other, which means that the angle between any two directions of the first direction, the second direction and the third direction is 90°. Figure 1 and Figure 2 As shown, the first direction is the up-down direction, the second direction is the left-right direction, and the third direction is the front-back direction.

For example, the driving device can drive the support frame 2 to rotate relative to the support frame 1 around any one of the first axis, the second axis, and the third axis; for another example, the driving device can drive the support frame 2 to rotate relative to the support frame 1 around any two of the first axis, the second axis, and the third axis; for another example, the driving device can drive the support frame 2 to rotate relative to the support frame 1 around the first axis, the second axis, and the third axis.

[0058] In this embodiment, when adjusting the angle of the toroidal field superconducting magnet 200, the lower end of the toroidal field superconducting magnet 200 is first fixedly mounted on the support frame 2, and then the driving device is fixedly connected to the toroidal field superconducting magnet 200. After that, the driving device can make the support frame 2 and the toroidal field superconducting magnet 200 fixedly mounted on the support frame 2 rotate relative to the support frame 1 around the first axis extending in the up-down direction, the second axis extending in the left-right direction and / or the third axis extending in the front-back direction, so that the rotation angle of the toroidal field superconducting magnet 200 can be effectively adjusted, thereby effectively adjusting the posture of the toroidal field superconducting magnet 200, avoiding collision and interference between the toroidal field superconducting magnet 200 and the cold shield sector of the vacuum chamber, thereby effectively ensuring the installation effect and effectively improving the assembly efficiency.

[0060] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the support frame 2 is rotatably connected to the support frame 1 through a first ball joint, and the assembly tool 100 also includes: a connecting frame 4, the connecting frame 4 is suitable for being fixedly connected to the toroidal field superconducting magnet 200, the connecting frame 4 and the support frame 2 are suitable for being arranged on two opposite sides of the toroidal field superconducting magnet 200 in a first direction, the connecting frame 4 is rotatably connected to the support frame 1 through a second ball joint 5, the first axis is a straight line passing through the center of the first ball joint and the center of the second ball joint 5, and the driving device includes a first driving component 31, and the first driving component 31 is used to drive the toroidal field superconducting magnet 200 to rotate around the first axis.

[0061] In a specific example, if Figure 1 and Figure 2 As shown, the first ball joint is arranged between the support frame 2 and the first adjustment mechanism 13. Furthermore, the first ball joint can adopt a spherical sliding bearing. Figure 1 and Figure 2As shown, the connecting member is arranged on the upper side of the toroidal field superconducting magnet 200, the support frame 2 is arranged on the lower side of the toroidal field superconducting magnet 200, and further, the connecting frame 4 and the support frame 2 are respectively fixedly connected to the upper side and the lower side of the toroidal field superconducting magnet 200. When the first driving assembly 31 is working, the first driving assembly 31 can drive the support frame 2, the toroidal field superconducting magnet 200 and the connecting frame 4 to rotate around the first axis, thereby completing the adjustment of the rotation angle of the toroidal field superconducting magnet 200 around the first axis.

[0062] In this embodiment, the support frame 2 is rotatably connected to the support frame 1 through a first ball joint, and the assembly tool 100 also includes: a connecting frame 4, the connecting frame 4 is suitable for being fixedly connected to the toroidal field superconducting magnet 200, the connecting frame 4 and the support frame 2 are suitable for being arranged on two opposite sides of the toroidal field superconducting magnet 200 in the first direction, the connecting frame 4 is rotatably connected to the support frame 1 through a second ball joint 5, and the first axis is a straight line passing through the center of the first ball joint and the center of the second ball joint 5, so that the toroidal field superconducting magnet 200 can rotate around the first axis, thereby effectively adjusting the rotation angle of the toroidal field superconducting magnet 200 around the first axis; by arranging a first driving component 31 in the driving device, the first driving component 31 is used to drive the toroidal field superconducting magnet 200 to rotate around the first axis, which can effectively improve the efficiency of rotating the toroidal field superconducting magnet 200.

[0063] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, there are multiple first drive components 31, and the multiple first drive components 31 are suitable for being respectively arranged on two opposite sides of the toroidal field superconducting magnet 200 in the second direction, one end of the first drive component 31 is fixed to the support frame 1 and the other end is suitable for being fixedly connected to the toroidal field superconducting magnet 200.

[0064] For example, the number of the first drive components 31 may be two, three, four, five or more than six, and the plurality of first drive components 31 are respectively arranged on the left and right sides of the toroidal field superconducting magnet 200. In a specific example, Figure 1 and Figure 2 As shown, there are three first drive assemblies 31 , one of which is disposed on the left side of the toroidal field superconducting magnet 200 , and the other two first drive assemblies 31 are disposed on the right side of the toroidal field superconducting magnet 200 and are spaced apart from each other.

[0065] In this embodiment, by setting the number of first drive components 31 to be multiple, the multiple first drive components 31 are suitable for being arranged on the two opposite sides of the toroidal field superconducting magnet 200 in the second direction, one end of the first drive component 31 is fixed to the support frame 1 and the other end is suitable for being fixedly connected to the toroidal field superconducting magnet 200, which can ensure that the driving force is evenly distributed on the toroidal field superconducting magnet 200, thereby helping to reduce the stress concentration caused by single-point force, thereby effectively improving the safety of the overall structure. In addition, it can also provide additional support for the toroidal field superconducting magnet 200, thereby helping to maintain the stability of the toroidal field superconducting magnet 200 during the adjustment process and reduce unnecessary vibration or shaking.

[0066] In one embodiment of the present invention, Figure 3 As shown, the first driving assembly 31 includes: a first fixing bracket 311 , a first connecting bracket 312 and a first driving member 313 .

[0067] The first fixed bracket 311 is fixed on the supporting frame 1; the first connecting bracket 312 is suitable for being fixedly connected to the toroidal field superconducting magnet 200; the first driving member 313 has a first fixed end and a first movable end movable along a third direction relative to the first fixed end, the first fixed end is connected to the first fixed bracket 311 through a ball joint, and the first movable end is connected to the first connecting bracket 312 through a ball joint.
