Description

Technical Field

[0001] This invention relates to the field of low-temperature performance testing of superconducting magnets in nuclear fusion engineering, specifically to an adjustable fixing fixture for high-field intercalation magnets. Background Technology

[0002] Steady-state strong magnetic fields are a crucial tool for cutting-edge scientific research. With the continuous development of superconducting application technology, high-field superconducting magnets have been widely used in fields such as biomedicine, scientific research, and power energy, including magnetic resonance imaging, nuclear magnetic resonance spectrometers, large particle accelerators, magnetically confined controlled nuclear fusion experimental devices, and superconducting magnetic energy storage devices. They have played a significant role in promoting the development of multiple disciplines such as physics, chemistry, materials science, and life sciences.

[0003] With the development of science, higher demands have been placed on strong magnetic field technology. Magnet devices that generate strong magnetic fields can be divided into three types: water-cooled magnets (also known as resistive magnets), superconducting magnets, and hybrid magnets. Water-cooled magnets, also known as resistive magnets, are solenoid magnets made of resistive conductors. Due to the resistance, they generate enormous heat when a large current is passed through them, requiring cooling with high-speed flowing deionized water, hence the name water-cooled magnets. Water-cooled magnets have fast excitation speeds and are relatively convenient to use, but they are large in size, consume a lot of energy, and have relatively high operating costs. Superconducting magnets are magnets wound with zero-resistance superconducting materials. Because the resistance of the coil conductor is zero, it can carry current without loss for a long time, requiring low power. At the same time, superconducting materials can have very high current densities, which greatly reduces the volume and mass of the magnet compared to water-cooled magnets. Therefore, superconducting magnets are widely used in industry, medicine, and scientific research.

[0004] With the development of superconducting technology, the magnetic field strength of superconducting magnets is expected to continue to increase in the future. Fully superconducting high-field steady-state magnets include low-temperature superconducting magnets and high-temperature superconducting magnets. Due to their size differences, to ensure that the magnetic field centers of the two types of superconducting magnets are located at the same position, it is necessary to design a supporting and fixing structure that enables the engineering assembly of the magnet system. This ensures that the magnet system can overcome the influence of the coupled electromagnetic force during excitation, allowing the fully superconducting steady-state magnet system to operate stably. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides an adjustable fixing clamp for an inserted high-temperature magnet, offering a robust mechanical support structure for a fully superconducting high-field hybrid magnet system. The adjustable clamp structure allows for adjustment of the axial and radial positions of the central solenoid magnet and the high-temperature superconducting magnet, ensuring the two magnet systems achieve the designed assembly precision. The adjustable clamp structure secures the high-temperature superconducting magnet within the central solenoid magnet and tightly connects it to the preload rod, overcoming the coupled induced electromagnetic force caused by magnet position misalignment during energization and excitation, thus protecting the operational safety of the high-field hybrid magnet system.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An adjustable fixing clamp for high-field intercalation magnets is used to fix a high-temperature superconducting magnet assembly inside a central solenoid magnet. The clamp includes a guide block, an upper circumferential fixing module, a lower load-bearing fixing module, and a locking rod. The guide block is installed on the upper end of a pre-tensioning rod of the central solenoid magnet. The upper circumferential fixing module includes a circumferential fixing block, a semi-circular clamping block, an inclined wedge, and a fixing clamping block. The semi-circular clamping block and the fixing clamping block are fastened to the pre-tensioning rod. The inclined wedge has a waist-shaped groove and is fastened to the semi-circular clamping block. The circumferential fixing block is movably placed on the upper surface of the semi-circular clamping block and contacts and engages with the inclined surface of the inclined wedge. The lower load-bearing fixing module includes a lower load-bearing clamp and a constraint fixing clamp. The carrier clamp includes a semi-circular carrier clamp, a carrier clamp, and a carrier fixing clamp. The semi-circular carrier clamp and the carrier fixing clamp are fastened to the pre-tensioning rod. The carrier clamp has an oblong groove and is fastened to the upper end face of the semi-circular carrier clamp. The constraint fixing clamp includes a constraint clamping block and a constraint fixing block, which are fastened to the pre-tensioning rod. The upper end of the locking rod is connected to the circumferential fixing block, and the lower end passes through the oblong through hole of the constraint clamping block and is fastened with a nut. The guide block is used to guide the high-temperature superconducting magnet assembly into the interior of the central solenoid magnet. The upper circumferential fixing module and the lower carrier fixing module are used to adjust the concentricity and symmetry of the high-temperature superconducting magnet assembly and the central solenoid magnet.

[0008] Furthermore, the guide block includes a base plate and a guide head. The base plate and the guide head are welded together as a whole. The base plate is provided with an oblong hole and is fixed to the upper end of the pretensioning rod by screws.

[0009] Furthermore, the inclined wedge and the circumferential fixed block are engaged through inclined surface contact, and the circumferential fixed block can slide along the inclined surface of the inclined wedge, forming a spatial circular structure with multiple circumferential fixed blocks.

[0010] Furthermore, the upper end of the locking rod is fixedly connected to the circumferential fixing block, and passes through the waist-shaped through hole of the semi-circular clamping block and the constraint clamping block in sequence.

[0011] Furthermore, the load-bearing clamp is fastened to the upper end face of the semi-circular load-bearing clamp by a waist-shaped groove and screws, and the semi-circular load-bearing clamp and the load-bearing fixing clamp are fastened to the pre-tensioning rod by bolts.

[0012] Furthermore, the constraint clamping block is provided with an oblong through hole, through which the lower end of the locking rod passes and is fastened to the lower end face of the constraint clamping block with a nut.

[0013] Furthermore, the locking rod connects the upper circumferential fixing module with the constraint fixing fixture to form a linkage assembly. The downward pulling action of the locking rod achieves a tight fit between the circumferential fixing block and the high-temperature superconducting magnet assembly.

[0014] Furthermore, the upper surface of the semi-circular bearing clamp of the lower bearing fixture is used to support the high-temperature superconducting magnet assembly and to position it axially. The bearing clamp is tightly assembled with the high-temperature superconducting magnet assembly and is circumferentially fixed to it.

[0015] Furthermore, the axial position of the upper circumferential fixing module is adjusted by tightening or loosening the bolts on the pre-tightening rod of the semi-circular clamping block and the fixed clamping block, and the axial position of the lower bearing fixing module is adjusted by tightening or loosening the bolts on the pre-tightening rod of the semi-circular bearing clamping block and the bearing fixed clamping block.

[0016] Furthermore, the waist-shaped hole of the guide block, the waist-shaped groove of the inclined wedge block, the waist-shaped groove of the bearing clamping block, and the waist-shaped through hole of the constraint clamping block are used to adjust the relative position and envelope diameter of each component.

[0017] Beneficial effects:

[0018] 1. The guide block of the present invention enables the inserted high-temperature magnet assembly to be smoothly assembled into the interior of the central solenoid magnet during the hoisting and lowering process.

[0019] 2. The upper circumferential fixing module and the lower bearing fixing module of the present invention can adjust the envelope assembly diameter of the fixing clamp block through the waist-shaped hole, effectively fixing and constraining the axial and radial direction of the inserted high-temperature magnet assembly, overcoming the coupling induced electromagnetic force generated by the central solenoid magnet in the high-temperature magnet system when it is energized, and realizing high-precision engineering assembly of the central solenoid magnet and the inserted high-temperature magnet.

[0020] 3. The circumferential fixing block in the upper circumferential fixing module of the present invention is assembled in conjunction with the locking rod and the constraint clamping block in the lower bearing module, so that the inserted magnet assembly can accurately fall into the lower bearing module during the final assembly process without assembly jamming. At the same time, the locking rod locks and fixes the circumferential fixing block, forming an effective radial fixing structure. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, the technical features involved in the various embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0032] like Figure 1As shown, the high-field hybrid magnet system involved in this invention includes a vacuum Dewar 1, a cryogenic cooling screen 2, a central solenoid magnet 3, a magnet support 4, and a high-temperature superconducting magnet assembly 5. The magnet support 4 is located inside the vacuum Dewar 1 and fixed to an external support base. The central solenoid magnet 3 is placed on top of the magnet support 4, and the cryogenic cooling screen 2 is also placed on top of the magnet support 4, surrounding the central solenoid magnet 3 and providing a vacuum insulation space for it, thus isolating it from radiative heat transfer through the inner wall of the vacuum Dewar 1. The high-temperature superconducting magnet assembly 5 is placed within the internal cavity of the central solenoid magnet 3 to form the high-field hybrid magnet system.

[0033] like Figure 2 As shown, the high-temperature superconducting magnet assembly 5 includes a high-temperature superconducting magnet support component 6, an HTS (High-Temperature Superconducting)-CICC (Cable Armored Conductor) magnet 7, and a high-temperature tightly wound magnet 8. The high-temperature tightly wound magnet 8 is fixed to the upper part of the high-temperature superconducting magnet support component 6, and the HTS-CICC magnet 7 is fitted onto the outside of the high-temperature tightly wound magnet 8 and the high-temperature superconducting magnet support component 6, forming a high-precision assembled whole, thereby forming the high-temperature superconducting magnet assembly 5.

[0034] like Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the high-field intercalation magnet adjustable fixing fixture of the present invention includes a guide block 10, an upper circumferential fixing module 11, a lower bearing fixing module 12, and a locking rod 13. The high-temperature superconducting magnet assembly 5 is placed in the internal cavity of the central solenoid magnet 3 through the high-field intercalation magnet adjustable fixing fixture. The structural characteristics of the high-field intercalation magnet adjustable fixing fixture are used to adjust the overall assembly accuracy of the central solenoid magnet 3, the HTS-CICC magnet 7, and the high-temperature tightly wound magnet 8, so as to achieve high-precision coaxiality and horizontal symmetry among the three magnets, and make the central magnetic field of the high-field hybrid magnet system meet the design requirements. The lower support fixing module 12 is freely adjustable in the axial direction of the pretensioning rod 9 by tightening and loosening the bolts of the clamp-type structure. After determining the axial assembly position of the HTS-CICC magnet 7 and the high-temperature tightly wound magnet 8, the bolts are tightened to fix the lower support fixing module 12 in the fixed position of the pretensioning rod 9. The lower support fixing module 12 can be used to constrain and limit the axial position of the HTS-CICC magnet 7 and the high-temperature tightly wound magnet 8, so that the axial accuracy of the magnet system during the assembly process meets the design requirements. Both the upper circumferential fixing module 11 and the lower support fixing module 12 are provided with radial waist-shaped hole structures. The set screws in the radial waist-shaped hole structures are used to adjust the assembly envelope diameter formed by the upper circumferential fixing module 11 and the lower support fixing module 12 in the radial direction. The radial position of the HTS-CICC magnet 7 and the high-temperature tightly wound magnet 8 in the central solenoid magnet 3 is limited and fixed by the envelope diameter, so that the radial accuracy of the magnet system during the assembly process meets the design requirements.

[0035] The guide block 10 is installed on the upper end of the pre-tightening rod 9 of the central solenoid magnet 3. The pre-tightening rod 9 is located in the inner hole of the central solenoid magnet 3 and is connected to the external screw through a structural pad, forming a clamping structure for the central solenoid magnet 3. A pre-tightening force is applied to the pre-tightening rod 9 and the external screw through bolts to overcome the axial electromagnetic force generated by the central solenoid magnet 3 during energization. The guide block 10 guides the high-temperature superconducting magnet assembly 5 into the internal space of the central solenoid magnet 3 and provides circumferential pre-constraint, allowing the high-temperature superconducting magnet assembly 5 to be smoothly assembled inside the upper circumferential fixing module 11 and the lower bearing fixing module 12. The upper circumferential fixing module 11 and the lower bearing fixing module 12 are fixed at the designed position of the pre-tightening rod 9, and their positions on the pre-tightening rod 9 can be adjusted through the adjustable structure of the upper circumferential fixing module 11 and the lower bearing fixing module 12. The guide block 10 of the high-field intercalated magnet adjustable fixing clamp is installed on the upper end of the pretension rod 9. The lower bearing fixing module 12 is fixedly installed on the lower part of the pretension rod 9. The upper circumferential fixing module 11 is installed in the middle of the pretension rod, between the guide block 10 and the lower bearing fixing module 12 of the pretension rod. The pretensioning rod 13 connects the constraint fixing clamp of the lower bearing fixing module 12 to the upper circumferential fixing module 11.

[0036] Preferably, the guide block 10 includes a base plate and a guide head, which are welded together as a whole. The base plate has an oblong hole. The guide block 10 is fixedly installed on the upper end of the pre-tightening rod 9 of the central solenoid magnet 3 using screws. The outer diameter of the support component of the high-temperature superconducting magnet assembly 5 is obtained by measurement. The four guide blocks 10 are fixed by adjusting the position of the oblong hole in the base plate. The four guide blocks 10 are mutually perpendicularly distributed on the horizontal plane formed by the upper surfaces of the multiple pre-tightening rods 9. The four guide blocks 10 form a reasonable overall assembly envelope diameter on the radial horizontal plane, which can constrain the offset of the high-temperature superconducting magnet assembly 5 in four directions on the horizontal plane, thus guiding the assembly of the high-temperature superconducting magnet assembly 5.

[0037] like Figure 7As shown, the upper circumferential fixing module 11 includes a circumferential fixing block 15, a semi-circular clamping block 16, an inclined wedge block 17, and a fixing clamping block 18. The semi-circular clamping block 16 and the fixing clamping block 18 are split clamping structures. The clamping structure formed by the semi-circular clamping block 16 and the fixing clamping block 18 is fastened to the pre-tensioning rod 9 by bolts. Tightening and loosening the bolts allows the axial position of the upper load-bearing fixing module 11 along the pre-tensioning rod 9 to be adjustable. The inclined wedge block 17 has a waist-shaped groove, and screws are used to tighten the inclined wedge block 17 to the semi-circular clamping block 16. The circumferential fixing block 15 is movably placed on the upper end face of the semi-circular clamping block 16. The inclined conical surface of the circumferential fixing block 15 is in contact with the inclined surface of the inclined wedge block 17. The axial fixing block 15 slides along the inclined surface of the inclined wedge block 17. The inner diameter of the structural space formed by multiple axial fixing blocks 15 is used to circumferentially fix the high-temperature superconducting magnet assembly 5, overcoming the radial displacement of the HTS-CICC magnet 7 and the high-temperature tightly wound magnet 8 under the background magnetic field of the central solenoid magnet 3.

[0038] like Figure 9 As shown, the lower support fixing module 12 includes a lower support clamp 14 and a constraint fixing clamp. The lower support clamp includes a semi-circular support clamp 21, a support clamp 22, and a support fixing clamp 23. The semi-circular support clamp 21 and the support fixing clamp 23 are split clamp structures. The clamp structure formed by the semi-circular support clamp 21 and the support fixing clamp 23 is fastened to the pre-tensioning rod 9 by bolts, and the axial fastening position of the pre-tensioning rod 9 is adjusted by loosening or loosening the bolts. The support clamp 22 is provided with a waist-shaped groove, and the support clamp 22 is fastened to the upper end face of the semi-circular support clamp 21 by screws. The envelope diameter of the semi-circular support clamp 21 is adjusted by the waist-shaped groove to provide circumferential and axial constraints on the high-temperature superconducting magnet assembly 5.

[0039] like Figure 8 As shown, the constraint fixing fixture includes a constraint clamping block 19 and a constraint fixing block 20. The constraint clamping block 19 and the constraint fixing block 20 are fastened to the pretensioning rod 9. Similarly, the fastening position in the axial direction of the pretensioning rod can be adjusted by loosening or tightening the bolts. The constraint clamping block 19 is provided with an oblong through hole. The lower end of the locking rod 13 passes through the oblong through hole of the constraint clamping block 19, and the lower end of the locking rod 13 is fastened to the lower end face of the constraint clamping block 19 with a nut.

[0040] The upper end of the locking rod 13 is connected to the circumferential fixing block 15. During the assembly of the high-temperature superconducting magnet assembly 5, the circumferential fixing block 15, through the movable nature of the inclined surface, forms an installation diameter larger than that of the high-temperature superconducting magnet assembly 5, allowing the high-temperature superconducting magnet assembly 5 to pass through the upper circumferential fixing module 11. After the high-temperature superconducting magnet assembly 5 is assembled with the lower bearing clamp 14, the circumferential fixing block 15, under the downward pull of the locking rod 13, tightly engages with the high-temperature superconducting magnet assembly 5 and forms a circumferential fixation.

[0041] After the lower support and fixing module 12 is installed, the high-temperature superconducting magnet assembly 5 is placed on the upper surface of the semi-circular support clamp 21, and the high-temperature superconducting magnet assembly 5 is axially positioned. The support clamp 22 is tightly assembled with the high-temperature superconducting magnet assembly 5, and the support clamp 22 is fastened to the semi-circular support clamp 21 by tightening screws in the waist-shaped groove on the support clamp 22, so as to fix the superconducting magnet assembly 5 circumferentially.

[0042] The upper end of the locking rod 13 is fixedly connected to the circumferential fixing block 15, passes sequentially through the waist-shaped through holes of the semi-circular clamping block 16 and the constraint clamping block 19, and the lower end of the locking rod 13 is locked to the lower end face of the constraint clamping block 19 with a nut. The locking rod 13 forms a reliable mechanical fixation between the structural space circumference formed by the multiple circumferential fixing blocks 15 of the upper circumferential fixing module 11 and the high-temperature superconducting magnet assembly 5.

[0043] The upper circumferential fixing module 11 and the lower bearing fixing module 12 form two spatial circumferences on the outer circumference of the high-temperature superconducting magnet assembly 5, which are used to limit the circumferential displacement of the HTS-CICC magnet 7 and the high-temperature tightly wound magnet 8 under the background magnetic field of the central solenoid magnet 3. At the same time, the lower bearing fixing module 12 restricts the spatial movement of the HTS-CICC magnet 7 and the high-temperature tightly wound magnet 8 in the axial direction through the semi-circular bearing clamp 21, ensuring the safety and reliability of the inserted high-temperature magnet under the action of the back field.

[0044] In summary, the high-temperature superconducting magnet assembly 5 is assembled with the central solenoid magnet 3 via an insertion method to form a coaxially symmetrical high-field hybrid magnet system. An adjustable fixing clamp for the high-field insertion magnet secures the inserted high-temperature superconducting magnet assembly 5 within the internal space of the central solenoid magnet 3. During the assembly process of the high-temperature superconducting magnet assembly 5, the guide block 10 of the adjustable fixing clamp first guides the high-temperature superconducting magnet assembly 5 into the internal cavity of the central solenoid magnet 3. The upper circumferential fixing module 11 and the lower bearing fixing module 12 of the adjustable fixing clamp are used to adjust the concentricity and horizontal symmetry of the axes of the high-temperature superconducting magnet assembly 5 and the central solenoid magnet 3, ensuring the overall assembly accuracy of the central solenoid magnet 3 and the high-temperature superconducting magnet assembly 5, so that the central magnetic field strength of the high-field hybrid magnet system meets the design requirements. This invention can effectively solve the problem of overall assembly accuracy of the inserted high-temperature superconducting magnet in a high-field hybrid magnet system, overcome the influence of the back field of the central solenoid magnet on the coupling electromagnetic force of the high-temperature superconducting magnet, and provide a good mechanical bearing structure for the inserted high-temperature superconducting magnet.

[0045] The foregoing described an embodiment of an adjustable fixing clamp for inserting a high-temperature magnet. Those skilled in the art will understand that various changes, modifications, substitutions, and variations can be made to the support structure for the inserting high-temperature magnet without departing from the principles and spirit of the present invention. However, all such modifications based on the present invention should fall within the protection scope of the appended claims.
