Description

Technical Field

[0001] The invention relates to the technical field of armored superconducting coil development, and in particular to a nuclear fusion armored superconducting coil flipping system and method. Background Art

[0002] Fusion energy is called the ultimate ideal clean energy by humans. The stable operation of nuclear fusion reactors requires magnetic field confinement. Currently, superconducting coils are the key components used in nuclear fusion reactors.

[0003] The armored superconducting coil not only provides a uniform magnetic field density, but also needs to ensure that the dimensional tolerances of the armored superconducting coil remain consistent before and after electrical insulation, and no deformation may occur during the coil winding production, heat treatment and insulation wrapping process. Since the main material of the current CI CC superconducting coils is Nb3Sn, and the superconducting coils made of Nb3Sn material need to undergo heat treatment to exhibit strong superconducting properties, this means that after the superconducting coils are wound, they need to be flipped and hoisted into the heat treatment device and then flipped before insulation wrapping can be performed. Therefore, the transportation and flipping of the armored superconducting coils is inevitable.

[0004] However, in the current production and development process, people are accustomed to using cranes to lift and circulate superconducting coils. The lifting and turning process of superconducting coils requires a large workload, which requires comprehensive and detailed overall arrangements and a large number of operators. This process is prone to increase the probability of personnel making mistakes and increase labor costs due to low redundant personnel efficiency. Secondly, during the lifting and turning process of superconducting coils, due to problems such as the mismatch of the material, specifications and models of the slings or wire ropes and the unreasonable selection and design of the lifting tooling, the superconducting coils are subjected to uneven force, and deformations of varying degrees occur, and even brittle fracture of the Nb3Sn metallographic structure inside the conductor occurs. Thirdly, since the main material of the nuclear fusion armored superconducting coil is Nb3Sn, which has a low hardness, there is still a risk of accidental deformation even if a 316LN stainless steel armor layer is added to the outer layer of Nb3Sn, which in turn affects the excellent performance of the magnetic field generated by the superconducting coils.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Reference Figure 1 and Figure 2 As shown, the present invention is a nuclear fusion armored superconducting coil flipping system, including a motor 1, a movable end of the motor 1 is fixedly connected to a rotating shaft 11, the rotating shaft 11 is connected to a hemispherical tray structure 13 through a gear pair 19, a bearing 12 is arranged on the side of the hemispherical tray structure 13 away from the gear pair 19, and the bearing 12 is connected to a bearing box 10 through the rotating shaft 11, wherein the setting of the gear pair 19 can make the rotation angle of the hemispherical tray structure 13 more controllable, and the setting of the bearing 12 and the bearing box 10 makes the rotation of the hemispherical tray structure 13 smoother, thereby improving the working efficiency of the system.

[0028] The hemispherical tray structure 13 is provided with an electromagnetic coil 18 inside, and a positioning notch 21 is provided on the top surface of the hemispherical tray structure 13. When the electromagnetic coil 18 is energized, a magnetic field is generated. Figure 2 As shown, the electromagnetic coil 18 is set to be hemispherical, and the electromagnetic coil 18 will generate heat when energized. The electromagnetic coil 18 is set to be hemispherical, and the radius of the top coil is larger, which avoids the direct impact of the coil heating on the superconducting coil 20 above it, ensures the quality of the superconducting coil 20, and improves the safety of the system. The setting of the hemispherical tray structure 13 makes the distance between the surface of the electromagnetic coil 18 and the outer surface of the hemispherical tray structure 13 uniform, which is beneficial to the uniform heat dissipation of the electromagnetic coil 18, thereby maintaining the stability of the magnetic field generated by it, and further improving the stability of the system.

[0029] This system also includes a fastening and lifting upper splint 15 and a fastening and lifting lower splint 17, the inner sides of the fastening and lifting upper splint 15 and the fastening and lifting lower splint 17 are fixedly connected by a plurality of inner ring fastening bolts 16, and the outer sides of the fastening and lifting upper splint 15 and the fastening and lifting lower splint 17 are fixedly connected by a plurality of outer ring fastening bolts 14, wherein the material of the fastening and lifting upper splint 15 can be selected as carbon steel, and the magnetic field generated when the electromagnetic coil 18 is energized can adsorb the fastening and lifting upper splint 15 made of carbon steel, and correspondingly, the material of the fastening and lifting lower splint 17 can also be selected as carbon steel.

[0030] Among them, it should be supplemented that a superconducting coil 20 is arranged between the fastening and lifting upper clamp 15 and the fastening and lifting lower clamp 17; the outer circle fastening bolts 14 and the inner circle fastening bolts 16 are positioned on the upper surface of the hemispherical tray structure 13 through the positioning recesses 21, and such a setting makes it easy to fasten the upper lifting clamp 15, the fastening and lifting lower clamp 17 and the superconducting coil 20 as a whole and place it on the upper surface of the hemispherical tray structure 13, thereby further improving the flipping efficiency of the system.

[0031] The system also includes a receiving device for placing a whole composed of the upper clamping plate 15 for fastening and lifting, the lower clamping plate 17 for fastening and lifting, and the superconducting coil 20.

[0033] In an optional embodiment, the system further includes a slide rail 9 , and a support frame 2 is disposed at the bottom end of the motor 1 and the bearing box 10 , and the bottom end of the support frame 2 is slidably connected to the slide rail 9 .

[0035] Among them, the horizontal adjustment pad 4 is used to adjust the horizontality of the top surface of the top plate 3. Several horizontal adjustment pads 4 are arranged in a ring shape around the central axis of the circumferential top ring 5. The top plate 3 is arranged in a circular ring shape. The flatbed truck 8 is controlled by the industrial computer to move. By maintaining the horizontality of the top plate 3, the placement of the superconducting coil 20 is more stable, reducing the risk of it slipping from the top plate 3. The controlled movement of the flatbed truck 8 improves the automation level of the system.

[0036] In an optional embodiment, the upper portion of the support frame 2 is configured as a triangle, the lower portion of the support frame 2 is configured as a rectangle, and the long side of the lower portion of the support frame 2 is configured parallel to the slide rail 9. Such a configuration utilizes the higher stability of the triangle, thereby improving the stability and reliability of the system during the flipping process.

[0037] This system greatly reduces the labor intensity of flipping the superconducting coil 20, reduces the cost of manual errors and time costs, significantly improves the flipping efficiency, and ensures the quality of the superconducting coil 20. The system has a sophisticated structure, convenient operation, and significantly improved stability and reliability, making it suitable for promotion and use.
