Abstract
Description
Technical Field
[0001] This application relates to the field of superconducting technology, and in particular to a superconducting device. Background Technology
[0002] Superconducting devices utilize the zero-resistance property of superconducting materials to achieve lossless current transmission, and they have extremely wide applications in fields such as magnetic resonance imaging, nuclear fusion research, and magnetic levitation trains. Superconducting devices can generate magnetic fields in the X, Y, and Z axes. A typical superconducting device consists of a frame and superconducting coils, with the coils mounted on the frame, which serves as the support for the coils. However, traditional superconducting devices often suffer from drawbacks such as excessive cold mass and slippage between the coils and the frame leading to quench loss. Summary of the Invention
[0003] One of the technical problems addressed by this application is how to improve the utilization efficiency of superconducting devices.
[0004] A superconducting device, comprising:
[0005] A central superconducting mechanism, a central superconducting coil, and a central support, wherein the two axial ends of the central superconducting coil abut against the central support;
[0006] A first superconducting mechanism includes two first superconducting units, located along a first direction radially to a central superconducting coil, with the central superconducting coil situated between the two first superconducting units. Each first superconducting unit includes a first superconducting coil and a first support. The first superconducting coil has multiple spaced-apart first fixed regions along its circumference, and the first support is fixedly connected to these first fixed regions.
[0007] The second superconducting mechanism includes two second superconducting units along a second direction radially to the central superconducting coil, the second direction being perpendicular to the first direction, the central superconducting coil being located between the two second superconducting units; the second superconducting unit includes a second superconducting coil and a second support, the second superconducting coil having a plurality of spaced second fixed regions along its circumference, the second support being fixedly connected to the second fixed regions.
[0008] In one embodiment, the central support includes two abutment members and a plurality of columns. The columns extend along the axial direction of the central superconducting coil. The plurality of columns are spaced apart around the central superconducting coil and pass through the abutment members. Two abutment members are spaced apart on the columns along the axial direction of the central superconducting coil. The two ends of the central superconducting coil abut against the two abutment members respectively.
[0009] In one embodiment, at least one of the two abutments is slidably connected to the column along the axial direction of the central superconducting coil.
[0010] In one embodiment, the central support further includes a reinforcing member connected between two adjacent columns, and the first support is fixedly connected to the reinforcing member.
[0011] In one embodiment, the central support further includes a mounting member fixedly connected to the column, the column being inserted into the mounting member along the axial direction of the central superconducting coil, and the two abutting members being located on the same side of the mounting member.
[0012] In one embodiment, the first support includes two first supports spaced apart along the second direction, with each end of the first support being fixedly connected to two different first fixed regions on the first superconducting coil. The first support includes two first clamping members spaced apart along the first direction, with the first superconducting coil clamped between the two first clamping members, and the second support is fixedly connected to the first clamping members.
[0013] In one embodiment, the first support further includes an inner connector and an outer connector spaced apart along the first direction. The two ends of the inner connector are connected to the two first clamping members closest to the central superconducting coil within the same first support, and the inner connector is fixedly connected to the central support. The two ends of the outer connector are connected to the two first clamping members furthest from the central superconducting coil within the same first support.
[0014] In one embodiment, the second support includes two second supports spaced apart along the first direction, with each end of the second support fixedly connected to two different second fixed regions on the second superconducting coil. The second support includes two second clamping members spaced apart along the second direction, with the second superconducting coil clamped between the two second clamping members.
[0015] In one embodiment, the second support further includes a fixing member connected between the two second clamping members and fixedly connected to the first bracket.
[0016] In one embodiment, the two first superconducting coils can extend into the space enclosed by the second superconducting coil.
[0017] One technical effect of one embodiment of this application is that, given that the two ends of the central superconducting coil abut against the central support, the first support is fixedly connected to a first fixed area spaced apart on the first superconducting coil, and the second support is fixedly connected to a second fixed area spaced apart on the second superconducting coil, the central support, the first support, and the second support can be roughly understood as a grid structure. This makes the coverage area formed by the central superconducting coil through the central support much smaller than the exposed area, the coverage area formed by the first superconducting coil through the first support much smaller than the exposed area, and the coverage area formed by the second superconducting coil through the second support much smaller than the exposed area, thereby significantly reducing the weight of the central support, the first support, and the second support. This reduces the weight of the entire superconducting device, enabling miniaturization and reducing the cooling time. Furthermore, it facilitates a compact design among the first superconducting coil, the second superconducting coil, and the central superconducting coil, shortening the distance between the first and second superconducting coils relative to the magnetic field center, thereby improving the utilization efficiency of the superconducting device.

Detailed Implementation
[0025] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0026] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.
[0027] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0028] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0029] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.
[0030] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.
[0031] See Figure 1 , Figure 2 , Figure 3 and Figure 6An embodiment of this application provides a superconducting device 10 including a central superconducting mechanism 300, a first superconducting mechanism 100, and a second superconducting mechanism 200. The central superconducting mechanism 300 includes a central superconducting coil 310 and a central support 320. The two axial ends of the central superconducting coil 310 abut against the central support 320, thus achieving a fixed connection of the central superconducting coil 310 on the central support 320. The central superconducting coil 310 can be generally cylindrical. Since the two axial ends of the central superconducting coil 310 abut against the central support 320, the sides of the central superconducting coil 310 are not covered by the central support 320. That is, the central support 320 only covers the end face of the central superconducting coil 310 and cannot cover the sides of the central superconducting coil 310. This means that most of the area of the central superconducting coil 310 is outside the coverage area of the central support 320, that is, the coverage area formed by the central superconducting coil 310 through the central support 320 is much smaller than the exposed area.
[0032] See Figure 2 , Figure 4 and Figure 5 The first superconducting mechanism 100 includes two first superconducting units 101 located radially along a first direction of a central superconducting coil 310. The central superconducting coil 310 is situated between the two first superconducting units 101. Each first superconducting unit 101 includes a first superconducting coil 110 and a first support 120, with the first support 120 fixedly connected to the central support 320. The first superconducting coil 110 has multiple first fixed regions 111, which are spaced circumferentially along the first superconducting coil 110. The first support 120 is fixedly connected to the first fixed regions 111. This means that the first support 120 covers the first superconducting coil 110 within the first fixed regions 111, but cannot cover other regions of the first superconducting coil 110 that are different from the first fixed regions 111. In other words, the first support 120 only covers a limited number of localized regions of the first superconducting coil 110, while most of the region of the first superconducting coil 110 remains uncovered by the first support 120. The area formed by all the first fixed regions 111 on the first superconducting coil 110 is the first coverage area, which is covered by the first support 120. The area on the first superconducting coil 110 that is different from the first fixed regions 111 is the first exposed area, which cannot be covered by the first support 120. That is, the first exposed area is outside the coverage area of the first support 120, and the first exposed area is much larger than the first coverage area. In other words, the coverage area formed by the first superconducting coil 110 through the first support 120 is much smaller than the exposed area.
[0033] See Figure 2 , Figure 3 and Figure 4The second superconducting mechanism 200 includes two second superconducting units 201, arranged along a second direction radially toward the central superconducting coil 310. This second direction is perpendicular to the first direction. The central superconducting coil 310 is located between the two second superconducting units 201. Each second superconducting unit 201 includes a second superconducting coil 210 and a second support 220, which is fixedly connected to a first support 120. The second superconducting coil 210 has multiple second fixed regions 211, which are spaced apart circumferentially along the second superconducting coil 210. The second support 220 is fixedly connected to the second fixed regions 211. It can be understood that the second support 220 covers the second superconducting coil 210 in the second fixed regions 211, but cannot cover other regions of the second superconducting coil 210 that are different from the second fixed regions 211. In other words, the second support 220 only covers a limited number of local areas of the second superconducting coil 210, while most areas of the second superconducting coil 210 will not be covered by the second support 220. The area formed by all the second fixed regions 211 on the second superconducting coil 210 is the coverage area, which is covered by the second support 220. The area on the second superconducting coil 210 that is different from the second fixed regions 211 is the second exposed area. This second exposed area cannot be covered by the second support 220; that is, the second exposed area is outside the coverage area of the second support 220, and this second exposed area is much larger than the second coverage area. In other words, the coverage area formed by the second superconducting coil 210 through the second support 220 is much smaller than the exposed area.
[0034] For ease of description, the three axes of a Cartesian coordinate system are used as references. The first direction can be understood as the X-axis, the second direction as the Y-axis, and the axis of the central superconducting coil 310 as the third direction, which can be understood as the Z-axis. Therefore, the first superconducting coil 110 can provide a magnetic field in the X-axis direction, the second superconducting coil 210 can provide a magnetic field in the Y-axis direction, and the central superconducting coil 310 can provide a magnetic field in the Z-axis direction. The center formed by the orthogonality of the magnetic fields in the X-axis, Y-axis, and Z-axis directions can be understood as the magnetic field center of the superconducting device 10.
[0035] In traditional superconducting devices, the coverage area formed by the central superconducting coil through the central support is much larger than the exposed area, and the coverage area formed by the first superconducting coil through the first support is also much larger than the exposed area. This results in a relatively large weight for the central support, the first support, and the second support. On the one hand, this increases the overall weight of the superconducting device, making miniaturization impossible and prolonging the cooling time. On the other hand, it prevents a compact design among the first, second, and central superconducting coils, resulting in a larger distance between the first and second superconducting coils relative to the magnetic field center, thus reducing the utilization efficiency of the superconducting device.
[0036] Regarding the superconducting device 10 in the above embodiments, given that the two ends of the central superconducting coil 310 abut against the central support 320 respectively, the first support 120 is fixedly connected to the first fixed area 111 spaced apart on the first superconducting coil 110, and the second support 220 is fixedly connected to the second fixed area 211 spaced apart on the second superconducting coil 210, the central support 320, the first support 120, and the second support 220 can be roughly understood as a grid structure. This makes the coverage area formed by the central superconducting coil 310 through the central support 320 much smaller than the exposed area, the coverage area formed by the first superconducting coil 110 through the first support 120 much smaller than the exposed area, and the coverage area formed by the second superconducting coil 210 through the second support 220 much smaller than the exposed area, thereby significantly reducing the weight of the central support 320, the first support 120, and the second support 220. This will reduce the weight of the entire superconducting device 10, thereby enabling a miniaturized design and reducing the cooling time of the superconducting device 10. On the other hand, it will facilitate a compact design between the first superconducting coil 110, the second superconducting coil 210, and the central superconducting coil 310, reducing the distance between the first superconducting coil 110 and the second superconducting coil 210 relative to the center of the magnetic field, thereby improving the utilization efficiency of the superconducting device 10.
[0037] See Figure 4 , Figure 5 and Figure 6In some embodiments, the central support 320 includes two abutment members 321 and multiple columns 322, the number of which can be three or four, etc. The columns 322 extend axially along the central superconducting coil 310, i.e., extend along the Z-axis. Multiple columns 322 are arranged around the central superconducting coil 310 and spaced apart circumferentially along the central superconducting coil 310. The columns 322 are simultaneously inserted through the two abutment members 321. The two abutment members 321 are spaced apart axially along the central superconducting coil 310 on the columns 322. The two ends of the central superconducting coil 310 abut against the two abutment members 321 respectively, thus achieving a grid-like structure for the central support 320, reducing the weight of the central support 320 and also reducing the coverage area of the central superconducting coil 310 by the central support 320.
[0038] See Figure 4 , Figure 5 and Figure 6 In some embodiments, at least one of the two abutment members 321 is slidably connected to the column 322 along the axial direction of the central superconducting coil 310. The abutment member 321, which can be slidably connected to the column 322, can abut against an elastic element. It is understood that during the operation of the superconducting device 10, the central superconducting coil 310 may contract along the Z-axis due to the influence of cryogenic temperature and electromagnetic force, making it difficult for the central support 320 to effectively fix the central superconducting coil 310, thereby affecting the reliability of the superconducting device 10. Given the elastic element, when the central superconducting coil 310 contracts in the Z-axis direction, the elastic element will automatically push the abutment member 321 closer to the central superconducting coil 310, ensuring that the abutment member 321 always abuts against the central superconducting coil 310, and also ensuring that the central support 320 effectively fixes the central superconducting coil 310, ultimately improving the reliability of the superconducting device 10.
[0039] See Figure 4 , Figure 5 and Figure 6 In some embodiments, the central support 320 further includes a reinforcing member 323, which is connected between two adjacent columns 322, and the first support 120 is fixedly connected to the reinforcing member 323. By providing the reinforcing member 323, the structural strength of the central support 320 can be improved, thereby enhancing the structural reliability of the superconducting device 10. Furthermore, it facilitates the fixed connection of the first support 120 to the entire central support 320 via the reinforcing member 323, thus improving the ease of installation of the first support 120 on the central support 320.
[0040] See Figure 4 , Figure 5 and Figure 6In some embodiments, the central support 320 further includes a mounting member 324, which is fixedly connected to the column 322. The column 322 passes through the mounting member 324 along the axial direction of the central superconducting coil 310, and two abutment members 321 are located on the same side of the mounting member 324. This can be understood as both abutment members 321 being located on the lower side of the mounting member 324. By providing the mounting member 324, the entire superconducting device 10 can be hoisted relative to the cryogenic thermostat.
[0041] See Figure 2 , Figure 4 and Figure 5 In some embodiments, the first support 120 includes two first support bodies 121, which are spaced apart along a second direction. The two ends of the same first support body 121 are respectively fixedly connected to two different first fixing regions 111 on the first superconducting coil 110. Each first support body 121 includes two first clamping members 1211, which are spaced apart along a first direction. The first superconducting coil 110 is clamped between the two clamping members 1211. Alternatively, bolts or other fasteners can be inserted between the two clamping members 1211, thereby bolting the first superconducting coil 110 to the clamping members 1211, further strengthening the connection between them. The second support 220 is fixedly connected to the first clamping members 1211, meaning the first clamping members 1211 can be fixedly connected to the reinforcing member 323 on the central support 320 by bolts, thus achieving a fixed connection between the first support 120 and the central support 320. The above design of the first support 120 can realize the grid structure of the first support 120, reduce the weight of the first support 120, reduce the coverage area of the first support 120 on the central superconducting coil 310, and reduce the distance between the first superconducting coil 110 and the center of the magnetic field.
[0042] See Figure 2 , Figure 4 and Figure 5In some embodiments, the first support 120 further includes an inner connector 131 and an outer connector 132, both extending a certain length along a second direction, such that the inner connector 131 and the outer connector 132 are spaced apart along a first direction. The two ends of the inner connector 131 are connected to the two first clamping members 1211 closest to the central superconducting coil 310 within the same first support 120, and the inner connector 131 is fixedly connected to the reinforcing member 323 of the central support 320. The two ends of the outer connector 132 are connected to the two first clamping members 1211 furthest from the central superconducting coil 310 within the same first support 120. By providing the inner connector 131 and the outer connector 132, the structural strength of the first support 120 can be improved, and the installation of the first support 120 can be facilitated.
[0043] See Figure 2 , Figure 4 and Figure 5 In some embodiments, the second support 220 includes two second support bodies 221, which are spaced apart along a first direction. The two ends of the same second support body 221 are respectively fixedly connected to two different second fixing regions 211 on the second superconducting coil 210. Each second support body 221 includes two second clamping members 2211, which are spaced apart along a second direction. The second superconducting coil 210 is clamped between the two clamping members 2211. Alternatively, bolts or other fasteners can be inserted between the two clamping members 2211, thereby bolting the second superconducting coil 210 to the clamping members 2211, further strengthening the connection between them. This design of the second support 220 achieves a grid-like structure, reduces its weight, decreases its coverage area on the central superconducting coil 310, and reduces the distance between the second superconducting coil 210 and the magnetic field center.
[0044] See Figure 2 , Figure 3 and Figure 4 In some embodiments, the second support 221 further includes a fixing member 2212, which is connected between the two second clamping members 2211. The fixing member 2212 and the first bracket 120 can be fixedly connected by bolts, thus realizing the fixed connection between the second bracket 220 and the first bracket 120.
[0045] See Figure 1 , Figure 3 and Figure 4In some embodiments, the two first superconducting coils 110 can extend into the space enclosed by the second superconducting coil 210. This can be understood as the second superconducting coil 210 being fitted over the first superconducting coil 110. This further improves the compact design of the first superconducting coil 110, the second superconducting coil 210, and the central superconducting coil 310, thereby further reducing the distance between the first and second superconducting coils 110 and the center of the magnetic field, and thus further improving the utilization efficiency of the superconducting device 10.
[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0047] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
