Description

Technical Field

[0001] This invention relates to the field of coil manufacturing tooling technology, and in particular to a support device for non-planar stellarator coils. Background Technology

[0002] A coil typically refers to a loop of wire. The most common applications of coils include motors, inductors, transformers, and loop antennas. However, coils used in stellarators are often designed as complex non-planar coils due to the need to generate complex magnetic field configurations and the constraints of plasma. In order to generate a uniform magnetic field and ensure the continuous and stable operation of the stellarator during subsequent experiments, the three-dimensional dimensional accuracy of the coil is required to be extremely high.

[0003] Therefore, during the coil winding process, the coil is usually fixed on a coil support base machined by a five-axis machine tool. The bottom and sides of the coil support base must be completely in contact with the coil surface. After the coil is wound, it is usually necessary to wait for subsequent coil VPI casting treatment (vacuum pressure impregnation process) and coil box placement. Typically, there is a waiting time from the completion of coil winding to the subsequent coil processing. This requires the non-planar coil to be temporarily placed for a period of time. Since the coil itself is an extremely complex non-planar structure, in order to ensure that the coil does not deform during temporary placement and transportation, it is usually necessary to place the non-planar coil on a specially designed support structure. Each support structure can only be used for one specific type of coil. When the shape of the coil required by the stellarator changes, the support structure needs to be redesigned, which not only increases the cost of coil production but may also delay the coil production cycle. Summary of the Invention

[0004] The purpose of this invention is to solve the technical problem in the prior art that requires the design of separate support structures for non-planar coils with different shapes, which not only increases the cost of coil production but may also delay the production cycle of the coil.

[0005] To address the aforementioned technical problems, embodiments of the present invention disclose a support device for a nonplanar stellarator coil, wherein the coil is a nonplanar toroidal coil. This support device includes a base and a plurality of support components spaced apart circumferentially along the base. The plurality of support components are used to support the coil at multiple positions spaced apart circumferentially.

[0006] Each support component includes a height adjustment component, an angle adjustment component, and a mounting component. The height adjustment component extends parallel to the height direction of the base, and one end of the height adjustment component along its height direction is connected to the corresponding position of the base, while the other end is connected to the mounting component through the angle adjustment component. The mounting component has a mounting groove for embedding the side wall of the coil at the corresponding position.

[0007] Furthermore, the height adjustment component can adjust the height position of the mounting component relative to the base in the height direction, and the angle adjustment component can adjust the tilt angle of the mounting component relative to the height adjustment component in the height direction.

[0008] Using the above technical solution, this support device supports multiple support components via a base, ensuring stable placement of the support device. The corresponding parts of the coil are supported by mounting slots in the multiple support components. Furthermore, during use, each support component can be adjusted according to the shape of the non-planar toroidal coil at its corresponding position. Specifically, the height of the mounting component relative to the base is adjusted by a height adjustment component, and the tilt angle of the mounting component relative to the height direction is adjusted by an angle adjustment component. This allows the corresponding position of the coil to fit snugly into the mounting slot of the mounting component, ensuring that the coil's shape does not deform when the support device supports the non-planar toroidal coil, thus improving the coil's manufacturing precision.

[0009] Therefore, the support device provided in this embodiment can adjust the mounting slot of the mounting component according to the shape of the coil, adapt to various non-planar toroidal coils with different shapes, and has strong applicability. It does not require a dedicated support structure according to the shape of the coil, which reduces the cost of the coil in the production process. Moreover, the adjustment of each support component is convenient, which simplifies the coil production process to a certain extent.

[0010] The present invention also discloses a support device for a non-planar stellarator coil. The mounting component includes a base plate and two side plates spaced apart on one side wall of the base plate. The opposing walls of the two side plates form a limiting surface, and the side wall of the base plate located between the two side plates forms a bottom surface. The two limiting surfaces and the bottom surface enclose a mounting groove. The bottom surface constitutes the bottom of the mounting groove, and the two limiting surfaces respectively constitute two opposing walls of the mounting groove along its width direction. Furthermore, the opening of the mounting groove faces away from the base plate, and the two opposing sides of the mounting groove along its length direction are open to allow the coil to pass through the mounting groove along its length direction.

[0011] The side wall of the base plate away from the mounting slot is connected to the angle adjustment component.

[0012] Using the above technical solution, the mounting component forms a mounting groove by means of a base plate and two side plates. The two sides of the mounting groove, which are arranged opposite each other along its length, are open, so that the coil can be continuously mounted on multiple mounting grooves. The part of the coil corresponding to the mounting groove can be inserted into the mounting groove from the groove opening. The angle adjustment component adjusts the tilt angle of the base plate, so that the limiting surfaces of the two side plates and the bottom of the groove on the base plate can accurately limit the corresponding wall surface of the coil. Whether in the coil resting stage or the transportation stage, this support device can prevent the part of the coil embedded in the mounting groove from deforming, ensuring that the coil can be supported according to the expected shape.

[0013] The embodiments of the present invention also disclose a support device for a non-planar stellarator coil, wherein a plurality of first support parts are provided on each limiting surface and a plurality of second support parts are provided on the bottom surface. Each first support part has three orthogonal rotational degrees of freedom relative to the corresponding limiting surface, and each second support part has three orthogonal rotational degrees of freedom relative to the bottom surface.

[0014] Furthermore, the two limiting surfaces abut against the corresponding wall surfaces of the coil's sidewall via the corresponding first support parts, and the bottom surface abuts against the bottom surface of the coil's sidewall via the corresponding second support parts.

[0015] By adopting the above technical solution, since the walls of the coil embedding mounting groove may have curved shapes, multiple first support parts with three orthogonal rotational degrees of freedom relative to the corresponding limiting surface are provided on each limiting surface, and a second support part with three orthogonal rotational degrees of freedom relative to the bottom surface is provided on the bottom surface. The two limiting surfaces can accurately support and limit the surface of the coil through the multiple first support parts, and the bottom surface can accurately support and limit the surface of the coil through the multiple second support parts, which further improves the limiting accuracy of the mounting groove for the coil embedding part. Moreover, since the first support parts and the second support parts can completely fit and abut against the corresponding wall surface of the coil, the corresponding part of the coil will hardly move after being embedded in the mounting groove. Therefore, this support device also improves the support stability of the coil.

[0016] The embodiments of the present invention also disclose a support device for a non-planar stellarator coil. A first mounting hole through the side plate is formed at the location corresponding to the first support part of the limiting surface. A first screw is provided in the first mounting hole. The end of the first screw near the limiting surface is ball-jointed to the corresponding first support part. The side of the first screw away from the limiting surface is connected to the corresponding side plate through a first locking member.

[0017] A second mounting hole is formed on the bottom surface at the location corresponding to the second support part, penetrating the bottom plate. A second screw is provided in the second mounting hole. The end of the second screw near the bottom surface is connected to the corresponding second support part by a ball joint. The side of the second screw away from the bottom surface is connected to the bottom plate through a second locking member.

[0018] Using the above technical solution, when the corresponding part of the coil is embedded in the mounting groove, the first support part on the limiting surface and the second support part on the bottom surface are adjusted in sequence so that the first support part is in contact with the wall surface of the corresponding side wall of the coil. Then, the first screw and the first locking piece are tightened, and the first support parts on both limiting surfaces are pressed against the corresponding side wall of the coil. The second support part is then in contact with the bottom surface of the side wall of the coil. Then, the second screw and the second locking piece are tightened, and the second support part on the bottom surface is pressed against the bottom surface of the side wall of the coil. This provides relatively stable and accurate support for the coil. When removing the coil from the support device, only the first and second locking pieces need to be loosened. This structure has the advantage of convenient assembly and disassembly while ensuring the stability and accuracy of the coil support.

[0019] An embodiment of the present invention also discloses a support device for a non-planar stellarator coil, wherein two side plates extend from one end near the base plate in a direction away from each other to form fixing plates, the fixing plates abutting against corresponding portions of the base plate and being fixedly connected to the base plate. Furthermore, a reinforcing rib is formed between each side plate and its corresponding fixing plate.

[0020] Using the above technical solution, the two side plates are fixedly connected to the base plate through corresponding fixing plates. The fixing plates abut against the corresponding parts of the base plate to play a positioning role, which helps to improve the assembly accuracy of the side plates and the base plate. In addition, the reinforcing ribs set between the side plates and the corresponding fixing plates improve the connection strength between the side plates and the fixing plates and prevent the limiting surfaces on the side plates from shifting.

[0021] The embodiments of the present invention also disclose a support device for a non-planar stellarator coil, wherein each fixed plate is provided with a plurality of adjustment holes, the plurality of adjustment holes are arranged at intervals along the length direction of the mounting groove, and each adjustment hole is configured as a strip hole extending along the width direction of the mounting groove.

[0022] Each adjustment hole is fitted with a fastener to detachably fix the fixing plate to the base plate. By adjusting the position of the fastener in the adjustment hole along its extension direction, the fixing position of the fixing plate relative to the base plate is changed, thereby adjusting the distance between the two limiting surfaces.

[0023] Using the above technical solution, each side plate can be adjusted relative to the base plate along the width direction of the mounting groove through the adjustment holes on the fixed plate, thereby adjusting the distance between the two limiting surfaces of the mounting groove, so that the mounting groove can be used for coils of different line widths, further improving the applicability of the support device.

[0024] The present invention also discloses a support device for a non-planar stellarator coil. The angle adjustment component includes an intermediate component, an angle adjustment component, and a connecting component. One end of the intermediate component is fixedly connected to the height adjustment component, and the other end is hinged to the mounting component through a first connecting shaft.

[0025] Furthermore, the angle adjusting component and the connecting component are located on one side of the intermediate component. The angle adjusting component is fixedly connected to the intermediate component by the angle locking component. The connecting component is located between the mounting component and the angle adjusting component. The connecting component is hinged to the angle adjusting component through the second connecting shaft and to the mounting component through the third connecting shaft.

[0026] When the angle locking component is in the unlocked state, the angle adjusting component can move relative to the intermediate component along its height direction, and drive the mounting component to swing relative to the intermediate component around the axis of the first connecting shaft through the connecting component, so as to adjust the tilt angle of the mounting component relative to the height adjusting component in the height direction.

[0027] Using the above technical solution, when adjusting the tilt angle of the mounting component relative to the height direction, the angle locking component is in the unlocked state, and the angle adjusting component moves along the height direction of the intermediate component. The connecting component drives the mounting component to swing around the first connecting shaft until the tilt angle of the mounting component relative to the height adjusting component matches the corresponding part of the coil. The angle locking component is then locked. At this time, the tilt angle of the mounting component relative to the height adjusting component will no longer change, thus assembling the coil more stably.

[0028] The embodiments of the present invention also disclose a support device for a non-planar stellarator coil, wherein the intermediate component is configured as an intermediate rod, the angle adjustment component is configured as an angle adjustment screw, and the connecting component is configured as a pull plate.

[0029] A mounting plate is installed on the intermediate rod at the position corresponding to the angle adjustment screw in its circumferential direction. The mounting plate is provided with a third assembly hole that cooperates with the angle adjustment screw. The angle adjustment screw passes through the third assembly hole and is fixedly connected to the mounting plate through an angle locking component, so that the angle adjustment component is fixedly connected to the intermediate rod through the mounting plate.

[0030] The first connecting shaft is provided with a first fastening structure. In the locked state, the first fastening structure fixes the intermediate part, the connecting shaft and the mounting part together. In the unlocked state, the mounting part can rotate relative to the intermediate part around the axis of the first connecting shaft.

[0031] The second connecting shaft and the third connecting shaft are respectively provided with a second fastening structure. In the locked state, the second fastening structure fixes the angle adjusting member, the second connecting shaft, the connecting member, the third connecting shaft and the mounting component together. In the unlocked state, the connecting member can rotate relative to the angle adjusting member and the mounting component, so that the angle adjusting member can drive the mounting component to swing relative to the intermediate component around the axis of the first connecting shaft through the connecting member.

[0032] By adopting the above technical solution, the angle adjusting screw can more accurately adjust the tilt angle of the mounting component relative to the intermediate part in the height direction. The pull plate set between the angle adjusting screw and the mounting component can make the swing of the mounting component smoother and reduce the possibility of jamming when the linear motion of the angle adjusting screw is converted into the rotational motion of the mounting component.

[0033] The present invention also discloses a support device for a non-planar stellarator coil. The height adjustment component includes a support member and a height adjustment member. One end of the support member is fixedly connected to the base, and the other end is fixedly connected to the height adjustment member through a height locking member. The end of the height adjustment member away from the support member is fixedly connected to an angle adjustment member.

[0034] When the height locking component is in the unlocked state, the height adjusting component can move relative to the support component along its height direction, so that the height position of the angle adjusting component and the mounting component relative to the base can be adjusted.

[0035] Using the above technical solution, when adjusting the position of the mounting component in the height direction, the height locking component is in the unlocked state, so that the height adjusting component moves relative to the support component in the height direction, thereby driving the mounting component to move in the height direction until the position of the mounting component in the height direction matches the corresponding part of the coil. At this time, the height locking component is locked, and the position of the mounting component in the height direction will no longer change, thus assembling the coil more stably.

[0036] The embodiments of the present invention also disclose a support device for a non-planar stellarator coil, wherein the support member is configured as a support rod and the height adjustment member is configured as a height adjustment screw.

[0037] The support rod has a fourth mounting hole at the end away from the base, which cooperates with the height adjustment screw. The height adjustment screw passes through the fourth mounting hole and is fixedly connected to the support rod through a height locking component. The end of the height adjustment screw away from the support rod is fixedly connected to the angle adjustment component through a pressure plate.

[0038] Using the above technical solution, the height adjustment screw can move accurately along the height direction and has good self-locking performance, preventing easy deviation and facilitating operator adjustment. Furthermore, the pressure plate ensures a reliable connection between the height adjustment screw and the angle adjustment component.

[0039] The beneficial effects of this invention are as follows:

[0040] This invention provides a support device for a non-planar stellarator coil. The support device includes a base and multiple support components spaced circumferentially along the base. These support components support the coil at multiple circumferentially spaced positions. Each support component includes a height adjustment component, an angle adjustment component, and a mounting component. The height adjustment component extends parallel to the height direction of the base, with one end connected to a corresponding position on the base and the other end connected to the mounting component via the angle adjustment component. The mounting component has a mounting groove for embedding the sidewall of the coil at the corresponding position. This support device adjusts the height of the mounting component relative to the base using the height adjustment component and adjusts the tilt angle of the mounting component relative to the height direction using the angle adjustment component. This allows the coil to fit snugly into the mounting groove of the mounting component. In particular, when supporting a non-planar toroidal coil, the coil's shape remains undeformed, improving the coil's manufacturing precision. Attached Figure Description

[0055] As mentioned in the background section, existing support structures require specialized design for coils, especially non-planar toroidal coils used in stellarators. When the shape of the coils required by the stellarator changes, the support structure needs to be redesigned, which not only increases the cost of coil production but may also delay the production cycle of the coils.

[0056] To address this, the present invention provides a support device for a non-planar stellarator coil. This support device includes a base and a plurality of support components spaced circumferentially along the base. Each support component includes a height adjustment component, an angle adjustment component, and a mounting component. One end of the height adjustment component is connected to a corresponding position on the base, and the other end is connected to the mounting component via the angle adjustment component. The mounting component has a mounting groove for embedding the sidewall of the coil at a corresponding position. This support device adjusts the height of the mounting component relative to the base using the height adjustment component and adjusts the tilt angle of the mounting component relative to the height direction using the angle adjustment component, allowing the coil to fit snugly into the mounting groove of the mounting component. This support device can adjust the mounting groove of the mounting component according to the coil's shape, adapting to various non-planar toroidal coil shapes. In particular, when supporting a non-planar toroidal coil, the coil's shape remains undeformed, improving the coil's manufacturing precision.

[0057] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0058] like Figure 1 and Figure 2As shown, this embodiment provides a support device 10 for a non-planar stellarator coil. This support device 10 is particularly suitable for a non-planar toroidal coil 20. Of course, a planar toroidal coil 20 can also be supported by this support device 10.

[0059] Specifically, this support device 10 includes a base 100 and a plurality of support components 200 spaced circumferentially along the base 100. The plurality of support components 200 are used to support the coil 20 at multiple positions spaced circumferentially along its base. It should be noted that the support device 10 may have two, three, four, five or other numbers of support components 200 spaced circumferentially along the base 100, and this embodiment does not limit this to a single number.

[0060] The base 100 is mainly used to support multiple support components 200, and can be a frame formed by splicing together multiple frame beams, for example... Figure 1 The pentagonal frame is formed by splicing five frame beams, and the ends of two adjacent frame beams can be connected by welding. Alternatively, it can be a hexagonal frame formed by splicing six frame beams, or a ring frame formed by curved beams. This embodiment does not limit this to a single type.

[0061] Each support assembly 200 includes a mounting component 210, an angle adjustment component 220, and a height adjustment component 230. The height adjustment component 230 extends parallel to the height direction of the base 100, and one end of the height adjustment component 230 along its height direction is connected to the corresponding position of the base 100, while the other end is connected to the mounting component 210 through the angle adjustment component 220. The mounting component 210 has a mounting groove for embedding the side wall of the coil 20 at the corresponding position.

[0062] This support device 10 supports multiple support components 200 via a base 100, ensuring the support device 10 can be placed relatively stably. The corresponding parts of the coil 20 are supported by the mounting slots of the multiple support components 200. Furthermore, during use, each support component 200 can be adjusted according to the shape of the non-planar toroidal coil 20 at the corresponding parts of the multiple support components 200. Specifically, the height of the mounting component 210 relative to the base 100 is adjusted by the height adjustment component 230, and the tilt angle of the mounting component 210 relative to the height direction is adjusted by the angle adjustment component 220. This allows the corresponding position of the coil 20 to fit snugly into the mounting slot of the mounting component 210, ensuring that the shape of the coil 20 itself does not deform when the support device 10 supports the non-planar toroidal coil 20, thus improving the production precision of the coil 20.

[0063] Therefore, the support device 10 provided in this embodiment can adjust the mounting groove of the mounting component 210 according to the shape of the coil 20, adapt to various non-planar ring coils 20 with different shapes, and has strong applicability. It does not require a dedicated support structure according to the shape of the coil 20, which reduces the cost in the production process of the coil 20. Moreover, the adjustment of each support component 200 is convenient, which simplifies the production process of the coil 20 to a certain extent.

[0064] The mounting component 210 will be described in detail below.

[0065] like Figure 3 As shown, the mounting component 210 mainly assembles the corresponding part of the coil 20 through the mounting groove. Specifically, it may include a base plate 211 and two side plates 212 spaced apart on one side wall of the base plate 211. The opposing walls of the two side plates 212 form a limiting surface, and the side wall of the base plate 211 located between the two side plates 212 forms a bottom surface. The mounting groove is formed by the two limiting surfaces and the bottom surface, and the bottom surface constitutes the bottom of the mounting groove. The two limiting surfaces respectively form two opposing walls of the mounting groove along its width direction. The other side wall of the base plate 211 away from the mounting groove is connected to the angle adjustment component 220. It should be noted that the dimension of the mounting groove along its width direction can be smaller or larger than the dimension of the mounting groove along its length direction. This embodiment does not limit this.

[0066] Furthermore, the opening of the mounting slot faces away from the base plate 211, and the two sides of the mounting slot that are arranged opposite each other along its length are open so that the coil 20 can pass through the mounting slot along the length of the mounting slot, and the coil 20 can be continuously arranged on multiple mounting slots.

[0067] During use, the part of coil 20 corresponding to the mounting groove can be inserted into the mounting groove from the groove opening. The angle adjustment component 220 adjusts the tilt angle of the base plate 211 so that the limiting surfaces of the two side plates 212 and the bottom of the groove on the base plate 211 can accurately limit the corresponding wall surface of coil 20. Whether in the static stage or the transportation stage of coil 20, this support device 10 can prevent the part of coil 20 embedded in the mounting groove from deforming, ensuring that coil 20 can be supported according to the expected shape.

[0068] More specifically, the ends of the two side plates 212 near the base plate 211 extend in a direction away from each other to form fixing plates 217. The fixing plates 217 abut against the corresponding portions of the base plate 211 and are fixedly connected to the base plate 211. Furthermore, a reinforcing rib 218 is formed between each side plate 212 and the corresponding fixing plate 217.

[0069] The two side plates 212 are fixedly connected to the base plate 211 by corresponding fixing plates 217. The fixing plates 217 abut against the corresponding parts of the base plate 211 to play a positioning role, which helps to improve the assembly accuracy of the side plates 212 and the base plate 211. Furthermore, the reinforcing ribs 218 provided between the side plates 212 and the corresponding fixing plates 217 improve the connection strength between the side plates 212 and the fixing plates 217, and prevent the limiting surface on the side plates 212 from shifting.

[0070] Furthermore, each fixing plate 217 is provided with a plurality of adjustment holes 219, which are arranged at intervals along the length of the mounting groove. For example, each fixing plate 217 may be provided with two, three, four, six or other numbers of adjustment holes 219. This embodiment does not limit this to a single number.

[0071] Specifically, each adjustment hole 219 is configured as a strip-shaped hole extending along the width direction of the mounting groove. A fastener (e.g., a bolt) passes through each adjustment hole 219 to detachably fix the fixing plate 217 to the base plate 211. Furthermore, by adjusting the position of the fastener within the adjustment hole 219 along its extension direction, the fixed position of the fixing plate 217 relative to the base plate 211 changes, thereby adjusting the distance between the two limiting surfaces. This allows the mounting groove to accommodate coils 20 of different wire widths, further improving the applicability of the support device 10. Alternatively, the two side plates 212 can also be fixedly connected to the base plate 211 through multiple circular holes provided on the fixing plate 217; the two side plates 212 can also be integrally formed with the base plate 211. This embodiment does not limit this to a single option.

[0072] Furthermore, such as Figure 4 As shown, since the various walls of the part where the coil 20 is embedded in the mounting groove may have curved shapes, the two limiting surfaces and the bottom surface on the mounting groove may not be able to completely fit the corresponding wall surfaces of the side wall of the coil 20. Therefore, as Figure 5 As shown, in this embodiment, multiple first support portions 213 can be provided on each limiting surface, and multiple second support portions 214 can be provided on the bottom surface. Each first support portion 213 has three orthogonal rotational degrees of freedom relative to the corresponding limiting surface, and each second support portion 214 has three orthogonal rotational degrees of freedom relative to the bottom surface.

[0073] In this embodiment, the two limiting surfaces abut against the corresponding wall surfaces of the sidewall of the coil 20 via corresponding first support portions 213, and the bottom surface abuts against the bottom surface of the sidewall of the coil 20 via corresponding second support portions 214. It should be noted that the first support portion 213 of one of the limiting surfaces abuts against the inner wall surface of the sidewall of the coil 20, and the first support portion 213 of the other limiting surface abuts against the outer wall surface of the sidewall of the coil 20. The inner wall surface of the sidewall of the coil 20 refers to the sidewall surface of the annular coil 20 closer to the center, and the outer wall surface refers to the sidewall surface of the annular coil 20 away from the center. The bottom surface of the sidewall of the coil 20 refers to the wall surface of the coil 20 along its thickness direction.

[0074] In this embodiment, the positioning accuracy of the mounting groove for the embedded portion of the coil 20 is further improved by multiple support portions. Since the first support portion 213 and the second support portion 214 can completely fit and abut against the corresponding wall surface of the coil 20, the corresponding portion of the coil 20 will hardly move after being embedded in the mounting groove. Therefore, this support device 10 also improves the support stability of the coil 20.

[0075] More specifically, the limiting surface is located at the position corresponding to the first support part 213 to form a first mounting hole through the side plate 212. A first screw 215 is provided in the first mounting hole. The end of the first screw 215 near the limiting surface is connected to the corresponding first support part 213 by a ball joint. The side of the first screw 215 away from the limiting surface is connected to the corresponding side plate 212 through a first locking member.

[0076] A second mounting hole is formed on the bottom surface at the location corresponding to the second support part 214, penetrating the bottom plate 211. A second screw 216 is provided in the second mounting hole. The end of the second screw 216 near the bottom surface is connected to the corresponding second support part 214 by a ball joint. The side of the second screw 216 away from the bottom surface is connected to the bottom plate 211 through a second locking member.

[0077] In this embodiment, when the corresponding part of the coil 20 is embedded in the mounting groove, the first support 213 on the limiting surface and the second support 214 on the bottom surface are adjusted in sequence so that the first support 213 is in contact with the wall surface of the corresponding side wall of the coil 20. Then, the first screw 215 and the first locking member are tightened, and the first support 213 on both limiting surfaces is pressed against the corresponding side wall of the coil 20. The second support 214 is in contact with the bottom surface of the side wall of the coil 20. Then, the second screw 216 and the second locking member are tightened, and the second support 214 on the bottom surface is pressed against the bottom surface of the side wall of the coil 20. This provides relatively stable and accurate support for the coil 20. When removing the coil 20 from the support device 10, it is only necessary to loosen the first locking member and the second locking member. This structure has the advantage of convenient assembly and disassembly while ensuring the stability and accuracy of the support for the coil 20.

[0078] It should be noted that the first support part 213 and the corresponding first screw 215 can also be flexibly connected. Similarly, the second support part 214 and the corresponding second screw 216 can also be flexibly connected. This ensures that when the first screw 215 presses against the first support part 213, elastic deformation can occur between the first screw 215 and the first support part 213, allowing the first support part 213 to fit against the corresponding wall surface of the side wall of the coil 20. When the second screw 216 presses against the second support part 214, elastic deformation can occur between the second screw 216 and the second support part 214, allowing the second support part 214 to fit against the bottom surface of the side wall of the coil 20. In addition, the first support part 213 and the corresponding first screw 215 can also be connected by a universal joint, and the second support part 214 and the corresponding second screw 216 can also be connected by a universal joint. In this embodiment, the connection method between the first screw 215 and the first support part 213, and between the second screw 216 and the second support part 214 is not limited to a single one.

[0079] The angle adjustment component 220 will be described in detail below.

[0080] like Figure 6 As shown, in this embodiment, the angle adjustment component 220 is used to adjust the tilt angle of the mounting component 210 relative to the height adjustment component 230 in the height direction. Specifically, it may include an intermediate component 221, an angle adjustment component 222, and a connector 223. One end of the intermediate component 221 is fixedly connected to the height adjustment component 230, and the other end is hinged to the mounting component 210 through a first connecting shaft.

[0081] Furthermore, the angle adjusting member 222 and the connecting member 223 are located on one side of the intermediate member 221. The angle adjusting member 222 is fixedly connected to the intermediate member 221 via the angle locking member 224. The connecting member 223 is located between the mounting member 210 and the angle adjusting member 222, and the connecting member 223 is hinged to the angle adjusting member 222 via the second connecting shaft and to the mounting member 210 via the third connecting shaft. It should be noted that when the mounting member 210 includes a base plate 211, the intermediate member 221 can be hinged to the side of the base plate 211 away from the mounting groove via the first connecting shaft, and the connecting member 223 can be hinged to the side of the base plate 211 away from the mounting groove via the third connecting shaft. Moreover, the hinge points of the intermediate member 221 and the base plate 211 and the hinge points of the connecting member 223 and the base plate 211 are spaced apart along the width direction of the mounting groove.

[0082] When adjusting the tilt angle of the mounting component 210 relative to the height direction, the angle locking component 224 is in the unlocked state, causing the angle adjusting component 222 to move along the height direction of the intermediate component 221, and driving the mounting component 210 to swing around the first connecting shaft through the connecting component 223 until the tilt angle of the mounting component 210 relative to the height adjusting component 230 matches the corresponding part of the coil 20, and then the angle locking component 224 is locked. At this time, the tilt angle of the mounting component 210 relative to the height adjusting component 230 will no longer change, thus assembling the coil 20 more stably.

[0083] More specifically, the intermediate component 221 is set as an intermediate rod 225, the angle adjusting component 222 is set as an angle adjusting screw 226, and the connecting component 223 is set as a pull plate 227.

[0084] An installation plate is provided on the intermediate rod 225 at the position corresponding to the angle adjusting screw 226 in its circumferential direction. The installation plate is provided with a third mounting hole that cooperates with the angle adjusting screw 226. The angle adjusting screw 226 passes through the third mounting hole and is fixedly connected to the installation plate through the angle locking member 224, so that the angle adjusting member 222 is fixedly connected to the intermediate part 221 through the installation plate. The angle locking member 224 can be a locking nut that cooperates with the angle adjusting screw 226.

[0085] In this embodiment, the angle adjusting screw 226 can more accurately adjust the tilt angle of the mounting component 210 relative to the intermediate component 221 in the height direction. The pull plate 227 set between the angle adjusting screw 226 and the mounting component 210 can make the swing of the mounting component 210 smoother and reduce the possibility of jamming when the linear motion of the angle adjusting screw 226 is converted into the rotational motion of the mounting component 210.

[0086] Furthermore, in order to improve the support stability of the support assembly 200, a first fastening structure is provided on the first connecting shaft. In the locked state, the first fastening structure fixes the intermediate part 221, the connecting shaft and the mounting part 210 together. In the unlocked state, the mounting part 210 can rotate relative to the intermediate part 221 around the axis of the first connecting shaft.

[0087] The second connecting shaft and the third connecting shaft are respectively provided with a second fastening structure. In the locked state, the second fastening structure fixes the angle adjusting member 222, the second connecting shaft, the connecting member 223, the third connecting shaft and the mounting member 210 together. In the unlocked state, the connecting member 223 can rotate relative to the angle adjusting member 222 and the mounting member 210, so that the angle adjusting member 222 can drive the mounting member 210 to swing relative to the intermediate member 221 around the axis of the first connecting shaft through the connecting member 223.

[0088] It should be noted that in this embodiment, the connecting shaft at each hinge can be a bolt, and the corresponding fastening structure can be a nut that mates with the bolt. When the nut is tightened relative to the bolt, the hinges cannot rotate relative to each other to ensure stability during the support process. During adjustment, the bolts corresponding to each nut need to be loosened. At this time, the angle adjusting screw 226 moves along the height direction and drives the pull plate 227 to rotate, causing the base plate 211 of the mounting component 210 to rotate around the first connecting shaft. Of course, the connecting shaft at each hinge can also be a light shaft. The surface of the light shaft has a pin hole that penetrates the light shaft radially. The fastening structure corresponding to the pin hole of the light shaft can be a pin. Those skilled in the art can design according to the actual situation and specific needs. This embodiment does not limit this to a single design.

[0089] Of course, the specific structures of the intermediate component 221, the angle adjustment component 222, and the connecting component 223 are not limited to the intermediate rod 225, the angle adjustment screw 226, and the pull plate 227 in the above embodiments. The intermediate component 221 can also be set as an intermediate plate. One end of the intermediate plate can be fixedly connected to the height adjustment component 230 by welding, bolting, or other means, and the other end is hinged to the mounting component 210 through the first connecting shaft. The intermediate plate can provide a larger connection area, enhancing the connection stability between the intermediate component 230 and the mounting component 210. The intermediate component 221 can also be set as a frame structure made of metal profiles (such as angle steel, channel steel, etc.) welded or bolted together. One end of the intermediate frame is connected to the height adjustment component 230, and the other end is hinged to the mounting component 210. This frame structure has high strength and rigidity, can withstand large external forces, and is suitable for occasions with high structural strength requirements.

[0090] The angle adjusting component 222 can also be configured as an angle adjusting rack, which is movably mounted on the intermediate component 221. One end of the angle adjusting rack is hinged to the mounting component 210. An angle adjusting gear is positioned between the intermediate component 221 and the angle adjusting rack, meshing with it. By rotating the gear, the angle adjusting rack moves linearly, causing the connecting component 223 and the mounting component 210 to oscillate around the first connecting shaft, thus achieving angle adjustment. The gear and rack mechanism features high transmission accuracy and smooth movement, accurately controlling the angle change of the mounting component 210. Alternatively, the angle adjusting component 222 can be configured as a cam mechanism, with a wheel mounted on the intermediate component 221. By rotating the cam, the cam's profile curve pushes the connecting component 223 to move, thereby causing the mounting component 210 to oscillate. The cam mechanism can be designed with various complex profile curves according to actual needs, achieving non-linear angle adjustment and meeting some special angle change requirements.

[0091] The connector 223 can also be configured as a linkage group consisting of two or more connecting rods connected sequentially through hinge points. One end of the linkage group is hinged to the angle adjusting component 222, and the other end is hinged to the mounting component 210. By rationally designing the length of the connecting rods and the position of the hinge points, a more complex swing trajectory and angle adjustment range of the mounting component 210 can be achieved. The connector 223 can also be an elastic connecting piece (such as a metal or plastic piece) with a certain degree of elasticity. One end of the elastic connecting piece is fixed to the angle adjusting component 222, and the other end is connected to the mounting component 210. During angle adjustment, the elastic connecting piece can adapt to the swing of the mounting component 210 through its own elastic deformation, making the angle adjustment smoother. At the same time, the elastic connecting piece can also play a certain buffering role, reducing the impact and vibration generated during angle adjustment and protecting related components from damage.

[0092] Furthermore, the angle adjustment component 220 may also consist only of a connecting base, on which an arc-shaped guide rail is provided. The mounting component 210 is slidably mounted on the arc-shaped guide rail via a slider, and the slider on the mounting component 210 can be locked by a locking member to prevent the mounting component 210 from shaking when supporting the coil 20. In summary, regarding the specific structure of the angle adjustment component 220, those skilled in the art can design it according to actual conditions and specific needs, and this embodiment does not limit it to a single specific design.

[0093] The height adjustment component 230 will be described in detail below.

[0094] like Figure 6 As shown, the height adjustment component 230 is used to adjust the position of the mounting component 210 in the height direction. Specifically, it may include a support component 231 and a height adjustment component 232. One end of the support component 231 is fixedly connected to the base 100, and the other end is fixedly connected to the height adjustment component 232 through a height locking component 233. The end of the height adjustment component 232 away from the support component 231 is fixedly connected to the angle adjustment component 220.

[0095] When adjusting the position of the mounting component 210 in the height direction, the height locking component 233 is in the unlocked state, causing the height adjusting component 232 to move relative to the support component 231 in the height direction, thereby driving the mounting component 210 to move in the height direction until the position of the mounting component 210 in the height direction matches the corresponding part of the coil 20. At this time, the height locking component 233 is locked, and the position of the mounting component 210 in the height direction will no longer change, thus assembling the coil 20 more stably.

[0096] Specifically, the support component 231 is configured as a support rod 234, and the height adjustment component 232 is configured as a height adjustment screw 235.

[0097] The support rod 234 has a fourth mounting hole at the end away from the base 100, which cooperates with the height adjustment screw 235. The height adjustment screw 235 passes through the fourth mounting hole and is fixedly connected to the support rod 234 through the height locking member 233. The end of the height adjustment screw 235 away from the support rod 234 is fixedly connected to the angle adjustment component 220 through the pressure plate 236. Specifically, when the angle adjustment component 220 includes the intermediate component 221, the end of the height adjustment component 232 away from the support component 231 is fixedly connected to the end of the intermediate component 221 opposite to the mounting component 210 through the pressure plate 236.

[0098] In this embodiment, the height adjustment screw 235 can move relatively accurately along the height direction and has good self-locking performance, preventing easy deviation and facilitating operator adjustment. Furthermore, the pressure plate 236 ensures a reliable connection between the height adjustment screw 235 and the angle adjustment component 220.

[0099] Of course, the specific structure of the support member 231 and the height adjusting member 232 is not limited to the support rod 234 and the height adjusting screw 235 in the above embodiments. The support member 231 can also be a support sleeve, and the height adjusting member 232 can be an inner rod sleeved inside the support sleeve. Multiple positioning holes are evenly arranged along the height direction on the inner rod and the support sleeve. The height of the inner rod relative to the support sleeve is fixed by inserting a height locking member 233 (such as a positioning pin) into the positioning holes of different heights, thereby adjusting the height of the entire support member 231. The height adjusting component 230 can also adopt the structure of a hydraulic lifting cylinder or an electric push rod. Those skilled in the art can design it according to the actual situation and specific needs. This embodiment does not limit it to a single design.

[0100] In summary, this invention provides a support device 10 for a non-planar stellarator coil, comprising multiple support components 200 mounted on a base 100. Each support component 200 specifically includes a mounting component 210, an angle adjustment component 220, and a height adjustment component 230. During use, the multiple support components 200 are first assembled onto the base 100. Specifically, the end of the support rod 234 of each support component 200 facing away from the height adjustment screw 235 is assembled at the corresponding position on the base 100, ensuring that the height adjustment screw 235 of each height adjustment component 230 is at its maximum extension position relative to the support rod 234. Then, the height adjustment screw 235 and angle adjustment screw 226 of each support component 200 are adjusted so that the mounting groove of the mounting component 210 matches the corresponding position of the coil 20. Finally, the height locking component 233 and angle locking component 224 are locked, embedding the corresponding position of the coil 20 into the mounting groove (see [link to documentation]). Figure 2Adjust the plurality of first support portions 213 and second support portions 214 on the mounting component 210 so that the first support portions 213 and second support portions 214 in the mounting groove are in contact with the corresponding wall surface of the coil 20 (see...). Figure 5 Then, tighten the first screw 215 and the second screw 216 until the first screw 215 and the second screw 216 on all mounting parts 210 are tightened, thus completing the support of the coil 20.
