Description

Technical Field

[0001] The present 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. No deformation may occur during the coil winding, heat treatment and insulation wrapping processes. 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 turnover process of superconducting coils is labor-intensive, requiring comprehensive and detailed planning and a large number of operators. This process can easily lead to an increased probability of human error and increased labor costs due to redundant personnel and low work efficiency. Secondly, during the lifting and flipping process of the superconducting coils, the superconducting coils are subjected to uneven force, deformations of varying degrees, and even brittle fracture of the Nb3Sn metallographic structure inside the conductor. Furthermore, since the main material of the nuclear fusion armored superconducting coils 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, thereby affecting the excellent performance of the magnetic field generated by the superconducting coils.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall 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, and a bearing 12 is provided 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 interior of the hemispherical tray structure 13 is provided with an electromagnetic coil 18, and the top surface of the hemispherical tray structure 13 is provided with a positioning notch 21. 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 conducive 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 number 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 number of outer ring fastening bolts 14. Among them, the material of the fastening and lifting upper splint 15 can be selected as carbon steel. When the electromagnetic coil 18 is energized, the magnetic field generated can adsorb the fastening and lifting upper splint 15 made of carbon steel. Accordingly, the material of the fastening and lifting lower splint 17 can also be selected as carbon steel.

[0030] Among them, it should be noted 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 ring fastening bolts 14 and the inner ring fastening bolts 16 are positioned on the upper surface of the hemispherical tray structure 13 through the positioning recess 21, and such a setting makes it easier for the fastening and lifting upper clamp 15, the fastening and lifting lower clamp 17 and the superconducting coil 20 to be placed on the upper surface of the hemispherical tray structure 13, thereby further improving the flipping efficiency of the system.

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

[0032] The system also includes an industrial computer for controlling the opening and closing of the motor 1 and the electromagnetic coil 18 .

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

[0034] Furthermore, in an optional embodiment, the receiving device includes a flatbed truck 8, the top surface of which is provided with a plurality of jacks 7 arranged in a ring shape, the movable end of the jack 7 is provided with a push rod 6, the top end of the push rod 6 is provided with a circumferential top ring 5, the top edge of the circumferential top ring 5 is provided with a plurality of horizontal adjustment pads 4, and the top surface of the horizontal adjustment pad 4 is provided with a top plate 3.

[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 this system.

[0036] In an optional embodiment, the upper part of the support frame 2 is set to a triangle, the lower part of the support frame 2 is set to a rectangle, and the long side of the lower part of the support frame 2 is set parallel to the slide rail 9. Such a setting takes advantage of 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.

[0038] The working principle of this system is now explained through its operation process:

[0039] Step 1: Control the motor 1 through the industrial computer to keep the top surface of the hemispherical tray structure 13 in a horizontal state; Step 2: Fix the superconducting coil 20 between the fastening and lifting upper clamping plate 15 and the fastening and lifting lower clamping plate 17 through the outer ring fastening bolts 14 and the inner ring fastening bolts 16, and place it on the top surface of the hemispherical tray structure 13, and keep the bottom end of the outer ring fastening bolts 14 or the inner ring fastening bolts 16 stuck in the positioning recess 21; Step 3: Start the electromagnetic coil 18 through the industrial computer. The magnetic field generated by the electromagnetic coil 18 after being energized will tightly bind the fastening and lifting upper clamping plate 15 to the top surface of the hemispherical tray structure 13; Step 4: Start the motor 1 through the industrial computer The hemispherical tray structure 13 rotates 180 degrees. At this time, the overall orientation of the upper clamping plate 15, the lower clamping plate 17 and the superconducting coil 20 is set; the fifth step: the flatbed truck 8 is controlled by the industrial computer to start, so that the top plate 3 moves to the bottom of the overall structure composed of the upper clamping plate 15, the lower clamping plate 17 and the superconducting coil 20; the sixth step: the electromagnetic coil 18 is controlled to be closed by the industrial computer, and the magnetic field of the electromagnetic coil 18 will disappear. Then the flatbed truck 8 is controlled by the industrial computer to continue to move, so that the overall structure composed of the upper clamping plate 15, the lower clamping plate 17 and the superconducting coil 20 is flipped over and enters the next step.

[0040] Among them, it needs to be supplemented that, when the hemispherical tray structure 13 is flipped, the support frame 2 can be pushed to slide on the slide rail 9 to avoid interference with the receiving device during the flipping process of the hemispherical tray structure 13; when the receiving device is controlled to move directly below the hemispherical tray structure 13, the support frame 2 can be pushed to slide on the slide rail 9 for fine-tuning to ensure that the top plate 3 is placed directly below the fastened lifting upper splint 15.

[0041] The above is a detailed description of an embodiment of the present invention. However, the content described is only a preferred embodiment of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
