Description

Technical Field

[0001] The present invention relates to the technical field of magnet support, and more particularly, to a supporting device for supporting a magnet. Background Art

[0002] In nuclear fusion engineering, magnetic confinement and controlled nuclear fusion energy is an unlimited, clean, and safe new energy source. The China Fusion Engineering Test Reactor (CFETR) is a major project currently underway to verify the feasibility of future commercial fusion reactors. The CFETR is the world's largest fusion test reactor to date. Its magnet system, a key component of the reactor, requires low-temperature physical performance testing of individual magnets, such as superconducting magnets, prior to final assembly to verify that their technical parameters and performance meet engineering design requirements.

[0003] The magnet system of the China Fusion Engineering Test Reactor (CFETR) includes longitudinal field coil magnets, poloidal field coil magnets, and central solenoid coil magnets. The longitudinal field coil magnets weigh approximately 600 tons, are approximately 20.5 meters long, and are approximately 12 meters wide. The support devices for low-temperature physical performance testing of large superconducting magnets for projects such as CFETR present engineering challenges. Large superconducting magnets have large structural dimensions and high overall weight loads. In particular, the structural shrinkage deformation of large superconducting magnets caused by their large structural volume in low-temperature testing environments poses significant difficulties in the engineering design of the support devices. The support devices for large superconducting magnets used in low-temperature physical performance testing not only require sufficient structural strength to ensure stable and safe operation of the superconducting magnets under various operating conditions, but also need to overcome the adverse effects of the magnet's shrinkage deformation in low-temperature environments and minimize low-temperature losses.

[0004] Currently, there are very few support devices for low-temperature physical performance tests of large superconducting magnets, especially those with asymmetric structural designs. For example, the low-temperature test support device for the longitudinal field coil of Japan's JT-60SA (superconducting tokamak nuclear fusion reactor) uses a three-point suspension method to support the superconducting magnet. However, the superconducting magnet weighs only 18 tons and has a maximum length of only 8.5 meters, making it difficult to support heavier and larger magnets. Summary of the Invention

[0040] In the description of the present invention, "first feature" and "second feature" may include one or more such features, "plurality" means two or more, the first feature being "above" or "below" the second feature may include the first and second features being in direct contact, or the first and second features not being in direct contact but being in contact through another feature between them, the first feature being "above", "above" and "above" the second feature includes the first feature being directly above and diagonally above the second feature, or simply means that the first feature is horizontally higher than the second feature.

[0041] The following describes a support device 100 for supporting a magnet according to an embodiment of the present invention with reference to the accompanying drawings. The support device 100 can be used to support a magnet during a low-temperature physical property test of the magnet, and of course, can also be used to support the magnet during other working processes.

[0042] Reference Figures 1-9 As shown, the supporting device 100 according to an embodiment of the present invention may include a supporting base 10 , a magnet supporting plate 20 and a plurality of supporting members 30 .

[0043] Specifically, the support base 10 can be placed on the ground to keep the support base 10 immobile, thereby improving the support stability of the support device 100 on the magnet. The magnet support plate 20 is provided above the support base 10 and is used to support the magnet. The above here can refer to the upper side of the support base 10 in the vertical direction, or the upper side of the support base 10 in a direction at a certain angle to the vertical direction.

[0044] The upper surface of the magnet support plate 20 can be a horizontal surface, and the magnet is supported on the upper side of the magnet support plate 20 of the multiple support devices 100, so that the pressure on the support device 100 is evenly distributed on the multiple support devices 100 and the multiple support members 30 of the support device 100, and then evenly distributed on each part of the support base 10, reducing the risk of damage to a single support member 30 due to excessive load, which is conducive to extending the service life of the support device 100. The upper surface of the magnet support plate 20 can be a horizontal surface, which can also make it difficult for the magnet to tilt or even slide off the magnet support plate 20, and the support device 100 has good support stability for the magnet. The support base 10 and the magnet support plate 20 can be made of higher strength materials to improve the load-bearing capacity of the support device 100, so that the support device 100 can support heavier magnets. The upper surface of the magnet support plate 20 can also be an irregular shape, etc.

[0045] The plurality of support members 30 are arranged at intervals between the support base 10 and the magnet support plate 20, so that the weight of the magnet is transferred to the magnet support plate 20 and then to the support base 10 through the plurality of support members 30. The overall force of the support device 100 can be adjusted by adjusting the number and arrangement of the plurality of support members 30. In the process of using the support device 100 to support the magnet, the pressure of the magnet can be evenly transferred to each support member through the magnet support plate 20, so that each support member 30 can be evenly stressed and the pressure evenly transferred to the support base 10. This not only improves the support stability of the support device 100, but also makes it less likely that a few support members 30 in the support device 100 bear a significantly higher weight than the other support members 30. This reduces the risk of damage to a single support member 30 due to excessive load and the possibility of damage to the support base 10 due to excessive local pressure. This helps to improve the overall load-bearing capacity of the support device 100, extend the service life of the support members 30 and the support base 10, and thus extend the service life of the support device 100.

[0046] For example, in some specific embodiments, Figure 1-Figure 3 As shown, there are nine support members 30 and the nine support members 30 are symmetrically arranged on a horizontal plane relative to the center line of the support base 10 so that the pressure from the magnet on the magnet support plate 20 can be more evenly transferred to all parts of the support base 10.

[0047] The support base 10 has a first connection portion 121 on one side facing the support member 30 , and the magnet support plate 20 has a second connection portion 21 on one side facing the support member 30 , for example Figure 2 and Figure 4-Figure 5As shown, the upper side of the support base 10 has a first connecting portion 121, and the lower side of the magnet support plate 20 has a second connecting portion 21. The support member 30 includes a first mating portion 31 and a second mating portion 33. The first mating portion 31 and the first connecting portion 121 are movably engaged in at least the horizontal and vertical directions, and the second connecting portion 21 and the second mating portion 33 are movably engaged in at least the horizontal and vertical directions.

[0048] For example, the movement between the first mating portion 31 and the first connecting portion 121 can be relative sliding, relative rotation, relative movement, or a combination of rotation and movement, allowing the support member 30 and the support base 10 to move relative to each other in the horizontal direction, the vertical direction, an angled direction at a certain angle to the horizontal direction, or other directions. For example, the mating method between the support member 30 and the support base 10 is a ball joint with multiple degrees of freedom. Specifically, for example, there is no connection between the first connecting portion 121 and the first mating portion 31, but they are merely in contact with each other. Another example is that the first connecting portion 121 and the first mating portion 31 have a partial connection but allow relative movement between the first connecting portion 121 and the first mating portion 31.

[0049] For example, the movement between the second mating portion 33 and the second connecting portion 21 can be relative sliding, relative rotation, relative movement, or a combination of rotation and movement, allowing the support member 30 and the magnet support plate 20 to move relative to each other in the horizontal direction, the vertical direction, an angled direction at a certain angle to the horizontal direction, or other directions. For example, the mating arrangement between the support member 30 and the magnet support plate 20 is a spherical joint with multiple degrees of freedom. Specifically, for example, the second connecting portion 21 and the second mating portion 33 have no connection but merely contact each other. Another example is a partial connection between the second connecting portion 21 and the second mating portion 33, but relative movement between the first connecting portion 121 and the first mating portion 31 is permitted.

[0050] The support member 30 and the support base 10 can move relative to each other, and the support member 30 and the magnet support plate 20 can move relative to each other, so that the magnet support plate 20 and the support base 10 can move relative to each other. For example, unlike the support base 10 which is fixed, the support member 30 can move relative to the support base 10, and the magnet support plate 20 can move relative to the support member 30. During the low-temperature physical property test of the magnet, the magnet will shrink in the low-temperature environment, and the magnet support plate 20 can move relative to the support base 10 as the magnet shrinks. Therefore, during the shrinkage of the magnet, the magnet support plate 20 moves with the magnet, and relative movement between the magnet and the magnet support plate 20 is not easy.

[0051] Compared to the friction generated by the relative movement of the magnet and the magnet support plate 20, the force that may be generated by the relative movement of the magnet support plate 20 and the support base 10 is more controllable, such as the friction between the support member 30 and the magnet support plate 20, and the friction between the support member 30 and the support base 10. Therefore, the movable connection between the magnet support plate 20 and the support base 10 allows the magnet support plate 20 to move with the magnet, making it difficult for the magnet and the magnet support plate 20 to move relative to each other, which helps to significantly reduce the friction that may be generated between the magnet and the support device 100.

[0052] The support member 30 enables the magnet support plate 20 to move relative to the support seat 10, so that the magnet support plate 20 can move accordingly during the deformation of the magnet, so that the support device 100 can provide a larger spatial displacement range for the magnet, so that the support device 100 can be used to support the magnet in a low-temperature environment with a lower temperature. It is not easy to generate friction between the magnet and the magnet support plate 20 to hinder the magnet from shrinking and deforming, or wear the magnet and the magnet support plate 20, which is conducive to reducing the adverse effects of the support device 100 on the magnet test results, making the results of low-temperature physical tests more accurate, thereby improving the stability and reliability of low-temperature physical performance tests, and extending the service life of the support device 100, effectively solving the adverse effects of the structural shrinkage deformation of the magnet in a low-temperature environment on the support device 100, so that the support device 100 can meet the support requirements of the magnet under low-temperature or even ultra-low-temperature conditions.

[0053] During the low-temperature physical properties test, the ground temperature is generally higher than the magnet temperature. Supporting the magnet on the support device 100 and placing the support device 100 on the ground can isolate the magnet from the ground. While ensuring that the support device 100's load-bearing capacity meets the requirements for supporting the magnet, increasing the height of the support device 100 can increase the distance between the magnet and the ground, effectively reducing the magnet's low-temperature loss, making the low-temperature physical test results more accurate, and improving the reliability of the low-temperature physical properties test.

[0054] The support device 100 has a stable support structure with high mechanical strength. The support device 100 can carry large superconducting magnets and has reliable structural stability. According to parameters such as the weight and size of different magnets, the number and arrangement of multiple support devices 100, such as the relative positions of multiple support devices 100, can be adjusted, and the number and arrangement of multiple support members 30 in each support device 100, such as the relative positions of multiple support members 30, can be adjusted. For example, the number of corresponding support devices 100 and the number of support members 30 in the corresponding support device 100 can be increased in areas where the magnet is heavier, so that multiple support devices 100 can be used to support multiple models of magnets of different weights and sizes, without having to design different support devices 100 for different models of magnets. Therefore, the support device 100 in the present application has a wider scope of application and is easy to promote and use.

[0055] For example, in some specific embodiments, by adjusting the number and arrangement of multiple support devices 100 and multiple support members 30 in each support device 100, multiple support devices 100 can be used to support large superconducting magnets weighing more than 600 tons, and the support devices 100 have strong load-bearing capacity and good support stability.

[0056] In addition, each supporting device 100 in the present application includes a supporting base 10, a magnet supporting plate 20 and a plurality of supporting members 30, and has a relatively simple structure and low manufacturing cost.

[0057] According to the support device 100 of the embodiment of the present invention, the load-bearing capacity and support stability of the support device 100 can be increased by adjusting the number and arrangement of multiple support devices 100 and adjusting the number and arrangement of multiple support members 30 in each support device 100, and the support member 30 is movably connected to the magnet support plate 20 and the support seat 10 at the same time, so that the magnet support plate 20 can move with the deformation of the magnet, is not easy to wear the magnet, and can provide a larger spatial displacement range for the magnet, effectively solving the adverse effects of the structural deformation of large magnets on the support device 100, which is conducive to extending the service life of the support device 100, making the support device 100 less likely to be deformed or even damaged in the process of supporting the magnet, and multiple support devices 100 can be used to support heavier and larger magnets, and the manufacturing cost of the support device 100 is low, and it is easy to promote and use.

[0058] In some embodiments of the present invention, Figure 2-Figure 4 and Figure 6 As shown, one of the first connecting portion 121 and the first matching portion 31 is a first groove, and the other of the first connecting portion 121 and the first matching portion 31 at least partially extends into the first groove and is movable in the first groove. The movement here can be a combination of one or more of rotation, sliding, movement, etc. Figure 2-Figure 4 and Figure 6As shown, the first connecting portion 121 is a first groove, and a portion of the first matching portion 31 extends into the first groove and is slidable and rotatable in the first groove.

[0059] For ease of understanding, the following explanation is given by taking the first connection portion 121 as the first groove as an example. Of course, an embodiment in which the first matching portion 31 is the first groove is also possible.

[0060] When the magnet is not deformed, the first mating portion 31 and the first groove are unlikely to move relative to each other, and the support stability is good. When the magnet is deformed, the magnet support plate 20 moves relative to the support base 10 along with the magnet, and at least a portion of the first mating portion 31 moves within the first groove.

[0061] The first engaging portion 31 is movable within the first groove, increasing the contact area between the first engaging portion 31 and the first groove when the dimensions of the support base 10 and the support member 30 are constant. This reduces the possibility of the first engaging portion 31 completely disengaging from the first groove under the pressure of the magnet, thereby improving the support reliability of the support device 100 when supporting the magnet. Increasing the contact area between the first engaging portion 31 and the first groove also increases the load-bearing capacity of the support device 100.

[0062] At least a portion of the first engaging portion 31 extends into the first groove and is movable within the first groove, so that the first engaging portion 31 is always engaged with the first groove. By controlling the shape and size of the first engaging portion 31 and the first groove, the relative range of motion of the support member 30 and the support seat 10 can be controlled, so that the relative range of motion of the support member 30 and the support seat 10 is not too small to meet the deformation and displacement requirements of the magnet, and the relative range of motion of the support member 30 and the support seat 10 is not too large to facilitate the subsequent restoration of the support member 30 and the support seat 10 to their original positions, that is, to the positions of the support member 30 and the support seat 10 when the support device 100 is not supporting the magnet, so that the support device 100 can perform the next work of supporting the magnet.

[0063] In some embodiments, as Figure 2-Figure 4 and Figure 6 As shown, the wall surface of the first groove is a concave arc surface, and the first matching portion 31 has a convex arc surface that matches the shape of the concave arc surface. For example, the diameter of the concave arc surface is the same as the diameter of the convex arc surface, so that the concave arc surface and the convex arc surface can completely match each other when there is no relative movement.

[0064] When the magnet is not deformed, the shapes of the concave arc surface and the convex arc surface match, making it difficult for the concave arc surface and the convex arc surface to move relative to each other. Therefore, the magnet is not easy to move relative to the supporting device 100, and the stability of the supporting magnet is better, which is conducive to improving the stability and reliability of low-temperature physical properties testing.

[0065] In the event of deformation of the magnet, the magnet support plate 20 moves along with the magnet relative to the support base 10, that is, the support member 30 moves relative to the magnet support plate 20, and the support member 30 moves relative to the support base 10. Because the concave and convex arc surfaces match in shape, the relative movement of the concave and convex arc surfaces during the movement of the support member 30 relative to the support base 10 is more stable, less prone to problems such as jamming, and can reduce interference with the magnet supported by the support device 100, improve the stability of the supported magnet, and help improve the stability and reliability of low-temperature physical property testing.

[0066] Therefore, by matching the concave arc surface of the first groove with the convex arc surface of the first matching portion 31 , the support device 100 can provide better support stability for the magnet whether the magnet is deformed or not.

[0067] In some embodiments of the present invention, Figure 2 and Figure 5-Figure 6 As shown, one of the second connecting portion 21 and the second matching portion 33 is a second groove, and the other of the second connecting portion 21 and the second matching portion 33 at least partially extends into the second groove and is movable in the second groove. The movement here can be a combination of one or more of the following movements: rotation, sliding, and movement. For example Figure 2 and Figure 5-Figure 6 As shown, the second connecting portion 21 is a second groove, and a portion of the second matching portion 33 extends into the second groove and is slidable and rotatable in the second groove.

[0068] For ease of understanding, the following explanation is given by taking the second connection portion 21 as the second groove as an example. Of course, an embodiment in which the second matching portion 33 is the second groove is also possible.

[0069] When the magnet is not deformed, the second mating portion 33 and the second groove are unlikely to move relative to each other, and the support stability is good. When the magnet is deformed, the magnet support plate 20 moves relative to the support base 10 along with the magnet, and at least a portion of the second mating portion 33 moves within the second groove.

[0070] The second mating portion 33 is movable within the second groove, increasing the contact area between the second mating portion 33 and the second groove when the dimensions of the magnet support plate 20 and the support member 30 are constant. This reduces the possibility of the second mating portion 33 completely detaching from the second groove under the pressure of the magnet, thereby improving the support reliability of the support device 100 when supporting the magnet. Increasing the contact area between the second mating portion 33 and the second groove can also increase the load-bearing capacity of the support device 100.

[0071] At least a portion of the second engaging portion 33 extends into the second groove and is movable within the second groove, so that the second engaging portion 33 is always engaged with the second groove. By controlling the shape and size of the second engaging portion 33 and the second groove, the relative range of motion of the support member 30 and the magnet support plate 20 can be controlled, so that the relative range of motion of the support member 30 and the magnet support plate 20 is not too small to meet the deformation and displacement requirements of the magnet, and the relative range of motion of the support member 30 and the magnet support plate 20 is not too large to facilitate the subsequent restoration of the support member 30 and the magnet support plate 20 to their original positions, that is, to the positions of the support member 30 and the magnet support plate 20 when the support device 100 is not supporting the magnet, so that the support device 100 can perform the next work of supporting the magnet.

[0072] In some embodiments, as Figure 2 and Figure 5-Figure 6 As shown, the wall surface of the second groove is a concave arc surface, and the other of the second connecting portion 21 and the second matching portion 33 has a convex arc surface that matches the shape of the concave arc surface. For example, the diameter of the concave arc surface is the same as the diameter of the convex arc surface, so that the concave arc surface and the convex arc surface can completely match each other when there is no relative movement.

[0073] When the magnet is not deformed, the shapes of the concave arc surface and the convex arc surface match, making it difficult for the concave arc surface and the convex arc surface to move relative to each other. Therefore, the magnet is not easy to move relative to the supporting device 100, and the stability of the supporting magnet is better, which is conducive to improving the stability and reliability of low-temperature physical properties testing.

[0074] When the magnet deforms, the magnet support plate 20 moves along with the magnet relative to the support base 10, that is, the support member 30 moves relative to the magnet support plate 20, and the support member 30 moves relative to the support base 10. Because the concave and convex arc surfaces match in shape, the relative movement of the concave and convex arc surfaces during the movement of the support member 30 relative to the magnet support plate 20 is more stable, and is less likely to cause problems such as jamming. This can reduce interference with the magnet supported by the support device 100, improve the stability of the supported magnet, and help improve the stability and reliability of low-temperature physical property testing.

[0075] Therefore, by matching the concave arc surface of the second groove with the convex arc surface of the second matching portion 33 , the support device 100 can provide better support stability for the magnet whether the magnet is deformed or not.

[0076] In some embodiments of the present invention, Figure 2 and Figure 6As shown, the support member 30 further includes a connecting section 32, which is connected between the first matching portion 31 and the second matching portion 33. The shape and size of the connecting section 32 are not limited, and the shape and size of the connecting section 32 can be adjusted to adjust the distance between the magnet support plate 20 and the support base 10, thereby adjusting the height of the support device 100 and the distance between the magnet and the ground. Figure 2-Figure 6 As shown, under the premise of ensuring that the support member 30 is not easily damaged, the size of the connecting section 32 in the vertical direction is increased to increase the size of the supporting device 100 in the vertical direction, which can support the magnet at a higher height to increase the distance between the magnet and the ground, thereby reducing the low-temperature loss of the magnet and maintaining the low-temperature state of the magnet.

[0077] like Figure 2 and Figure 7 As shown, the support device 100 further includes a limiting member 40, which is located between the support base 10 and the magnet support plate 20. The limiting member 40 cooperates with the plurality of support members 30 to limit the spacing between the plurality of support members 30. The limiting member 40 can cooperate with one or more of the first matching portion 31, the connecting section 32, and the second matching portion 33 of the support member 30.

[0078] By limiting the spacing between the plurality of support members 30 by the limiting member 40, the spacing between the plurality of first mating portions 31 and the plurality of second mating portions 33 of the plurality of support members 30 can be limited during the assembly process of the support device 100. After the plurality of first mating portions 31 of the plurality of support members 30 are mated one-to-one with the plurality of first connecting portions 121 of the support base 10, the plurality of second mating portions 33 of the plurality of support members 30 are mated one-to-one with the plurality of second connecting portions 21 of the magnet support plate 20. The plurality of second mating portions 33 can be quickly mated one-to-one with the plurality of second connecting portions 21 of the magnet support plate 20, or even simultaneously mated one-to-one with the plurality of second connecting portions 21, so that the magnet support plate 20 can be quickly installed on the plurality of support members 30, thereby improving the assembly efficiency of the support device 100.

[0079] In some embodiments, as Figure 2 and Figure 6 As shown, the first matching portion 31, the connecting section 32 and the second matching portion 33 define a non-spherical support member 30, which can reduce the possibility of the support member 30 being stuck between the first connecting portion 121 and the second connecting portion 21, thereby improving the reliability of the movable connection between the magnet support plate 20 and the support base 10. Specifically, as Figure 2 and Figure 6As shown, the first matching portion 31 and the second matching portion 33 are both hemispherical, and the connecting section 32 is a cylinder, so that the support member 30 is non-spherical and not easy to get stuck between the first connecting portion 121 and the second connecting portion 21. In addition, the support member 30 is an axially symmetrical shape, so that the force on the support member 30 is relatively uniform, reducing the possibility of damage to the support member 30 due to excessive local force, which is beneficial to extending the service life of the support member 30 and thus extending the service life of the support device 100.

[0080] In some embodiments, as Figure 2 and Figure 6-Figure 7 As shown, the limiting member 40 has a plurality of limiting holes 41, and the connecting sections 32 of the plurality of support members 30 are pluggably engaged with the plurality of limiting holes 41 in a one-to-one correspondence. The limiting member 40 cooperates with the plurality of connecting sections 32 to limit the relative positions of the plurality of support members 30. Therefore, the limiting member 40 does not easily affect the movable engagement between the first engaging portion 31 and the first connecting portion 121, or the movable engagement between the second engaging portion 33 and the second connecting portion 21. This facilitates balancing the limiting function of the limiting member 40 on the plurality of support members 30 and the movable connection of the magnet support plate 20 relative to the support base 10.

[0081] The structure of the support device 100 can be simplified by plugging and fitting the limiting holes 41 into the connecting sections 32. Furthermore, the plugging and fitting operation is simple, and a one-to-one correspondence between the multiple limiting holes 41 and the multiple connecting sections 32 can be quickly achieved. For example, by directly pressing the limiting member 40 against the multiple supporting members 30 so that the supporting members 30 pass through the corresponding limiting holes 41, the limiting member 40 can quickly limit the multiple supporting members 30, thereby improving the assembly efficiency of the support device 100.

[0082] In some embodiments, as Figure 2 and Figure 6-Figure 7 As shown, the connecting section 32 is cylindrical, which is easy to manufacture. The first matching portion 31 and the second matching portion 33 are connected in the length direction of the connecting section 32 (as shown in FIG. Figure 2 and Figure 6 At both ends of the connecting section 32 (in the up and down directions shown), there is a gap between the outer peripheral wall of the connecting section 32 and the hole wall of the limiting hole 41, that is, the connecting section 32 and the limiting hole 41 are clearance-matched, the plug-in operation speed is faster, and the assembly efficiency of the supporting device 100 is higher.

[0083] After the support device 100 is assembled, the limiting member 40 may still cooperate with the support member 30 , or the limiting member 40 may be separated from the support member 30 .

[0084] For example, in some embodiments, after the support device 100 is assembled, the limiting member 40 is still engaged with the connecting section 32, such as Figure 2As shown, after the support device 100 is assembled, the clearance between the connecting section 32 and the limiting hole 41 can be used to reduce the position interference of the limiting member 40 on the support member 30, allowing the support member 30 to move relative to the limiting member 40. Moreover, after the support member 30 moves to the point where the outer peripheral wall of the connecting section 32 contacts the hole wall of the limiting hole 41, it can drive the limiting member 40 to move together, so that the support member 30 and the limiting member 40 can move together relative to the magnet support plate 20 and the support base 10, thereby further increasing the range of movement of the support member 30, and thus increasing the range of movement of the magnet support plate 20 relative to the support base 10. Therefore, during the deformation process of the magnet, the magnet support plate 20 can move relative to the support base 10 through the movement of the support member 30, and the range of movement of the magnet support plate 20 relative to the support base 10 is large, which can provide a larger spatial displacement range for the magnet.

[0085] For example, in some embodiments where the limit member 40 is separated from the support member 30 after the support device 100 is assembled, the limit constraint of the limit member 40 on the support member 30 can be removed after the support device 100 is assembled, so that the limit member 40 is less likely to affect the movement of the support member 30 during the process of the support device 100 supporting the magnet, and the relative movement range of the magnet support plate 20 and the support seat 10 is wider, which can provide a larger spatial displacement range for the magnet.

[0086] In some embodiments of the present invention, Figure 1-Figure 2 and Figure 8 As shown, the support device 100 further includes a frame 50 and a fixing member 60, and the frame 50 is fixed above the support base 10. In the present application, the fixing connection method can be a combination of one or more of bolt connection, riveting, welding, etc., so that the connection is firm. For example, the frame 50 and the support base 10 are welded together and the connection is firm.

[0087] The position-limiting member 40 is located within the frame 50. The fixing member 60 is disposed within the frame 50 and is connected to the position-limiting member 40 to secure the position of the position-limiting member 40 within the frame 50. The fixing member 60 and the position-limiting member 40 are fixedly connected or detachably connected. The connection between the fixing member 60 and the frame 50 can be a combination of one or more of a bolt connection and a clip connection. The connection between the fixing member 60 and the position-limiting member 40 can be one or more of contact pressing, plug-in connection, bolt connection, and a clip connection. The fixing member 60 can be a screw, a bolt, or other component.

[0088] The connection between the frame 50 and the support base 10, and the connection between the fixing member 60 and the frame 50, can restrict the relative position of the fixing member 60 and the support base 10. Since the position of the fixing member 60 is fixed, the connection between the fixing member 60 and the limiting member 40 can fix the position of the limiting member 40 within the frame 50, thereby improving the limiting effect of the limiting member 40 on the multiple support members 30 during the assembly process of the support device 100.

[0089] After the support device 100 is assembled, the fixing member 60 may still be connected to the limiting member 40 , or the fixing member 60 may be separated from the limiting member 40 .

[0090] For example, in some embodiments where the fixing member 60 and the limiting member 40 are detachably connected, such as Figure 2 As shown, after the support device 100 is assembled, the fixing part 60 can be separated from the limiting part 40 to remove the limitation of the fixing part 60 on the limiting part 40, and then remove the limiting constraint of the limiting part 40 on the support part 30, so that the limiting part 40 is not likely to affect the movement of the support part 30 during the process of the support device 100 supporting the magnet, and the relative movement range of the magnet support plate 20 and the support seat 10 is wider, which can provide a larger spatial displacement range for the magnet.

[0091] For example, in some specific embodiments, Figure 1-Figure 2 As shown, the fixing member 60 is bolted to the frame 50. During assembly of the support device 100, the fixing member 60 can be bolted to the frame 50 and then inserted into the frame 50 to compress the stopper 40 and fix the position of the stopper 40. After assembly of the support device 100 is complete, the fixing member 60 can be removed from the frame 50 to remove the stopper 40 from the position. After the fixing member 60 is removed, the stopper 40 can fall to the upper surface of the support base 10, separating the stopper 40 from the support member 30.

[0092] In some embodiments, as Figure 2 As shown, part of the magnet support plate 20 is located inside the frame 50, so that the part of the magnet support plate 20 located outside the frame 50 can be used to support the magnet. The fixing member 60 is provided on the frame 50 and connected to the magnet support plate 20 to fix the position of the magnet support plate 20 inside the frame 50. During the assembly process of the support device 100, the position of the magnet support plate 20 can be limited by the fixed fixing member 60, which is conducive to making the upper surface of the magnet support plate 20 always horizontal and not easy to shake. After the support device 100 is assembled, the magnet can be placed above the horizontal upper surface of the magnet support plate 20, so that the magnet is not easy to tilt during the placement of the magnet. After the magnet is placed, the fixing member 60 can be removed to remove the limit on the magnet support plate 20, so that the magnet support plate 20 can move with the deformation of the magnet, and it is conducive to maintaining the horizontal state of the magnet and the upper surface of the magnet support plate 20 during the whole process of supporting the magnet, and supporting the magnet more stably.

[0093] In some embodiments of the present invention, the support device 100 includes a filler positioned between the stopper 40 and the support base 10 to support the stopper 40. The filler between the stopper 40 and the support base 10 supports the stopper 40. This facilitates placement of the stopper 40 on the support member 30 during assembly of the support device 100, facilitating assembly and maintaining the position-limiting effect of the stopper 40 on the multiple support members 30, thereby improving assembly efficiency of the support device 100. The filler can be a hard material or a deformable, flexible material such as foam.

[0094] In some embodiments of the present invention, Figure 2-Figure 4 As shown, the support seat 10 includes a seat body 11 and a plurality of support members 12. The seat body 11 has a plurality of mounting grooves 111. The plurality of support members 12 are detachably mounted in the plurality of mounting grooves 111 in a one-to-one correspondence. The first connecting portion 121 is provided on the support member 12. The connection between the seat body 11 and the support member 12 can be a combination of one or more of bolt connection, clamping, etc., for example Figure 2 As shown, the seat body 11 and the support member 12 are connected by a fastener 80, which can be a bolt. The bolt mentioned in this application can be a hexagon socket bolt, an external hexagon socket bolt or other bolts. For example, the fixing member 60 is a hexagon socket bolt and the fastener 80 is an external hexagon socket bolt.

[0095] The seat body 11 and the support component 12 are detachably connected, making the structural design of the support component 12 more flexible. For example, multiple support components 12 can be designed, and the shape, size and other parameters of the first connecting portion 121 in the multiple support components 12 can be different. The support component 12 installed in the installation groove 111 can be replaced to replace the support member 30 with different parameters such as shape and size, which is beneficial to improving the load-bearing capacity and support stability of the support device 100. The seat body 11 can be used to improve the overall load-bearing capacity of the support seat 10, for example, by selecting a material with higher strength to manufacture the seat body 11. The seat body 11 and the support component 12 can be made of the same or different materials as needed, which is beneficial to improving the load-bearing capacity of the support device 100 and reducing manufacturing costs.

[0096] The seat body 11 and the support component 12 are detachably connected, which also facilitates the installation, maintenance or partial replacement of the support seat 10. For example, if the support component 12 is damaged, the support component 12 can be directly replaced without replacing the entire support seat 10, which facilitates subsequent maintenance and effectively reduces the maintenance cost of the support seat 10.

[0097] In some embodiments, as Figure 2As shown, the projection of the support member 30 on the horizontal plane is located inside the support member 12, that is, the area of ​​the projection of the support member 12 on the horizontal plane is larger than the area of ​​the projection of the support member 30 on the horizontal plane, so that the first connecting portion 121 of the support member 12 can fully support the first matching portion 31 of the support member 30, and the first matching portion 31 is not easy to detach from the first connecting portion 121, which is beneficial to improving the supporting stability of the support seat 10 on the support member 30, so as to improve the supporting stability of the support device 100 as a whole in supporting the magnet.

[0098] In some embodiments of the present invention, Figure 2 As shown, the support device 100 includes a heat-insulating base plate 70, which is disposed on a side of the support base 10 away from the magnet support plate 20. The heat-insulating base plate 70, the base body 11, and the support member 12 are connected, for example, by bolts or other connection methods. The heat-insulating base plate 70 can be made of a heat-insulating material, for example, a glass fiber and resin composite material.

[0099] The heat-insulating bottom plate 70 is helpful in isolating the external high-temperature environment such as the ground temperature, thereby reducing the heat transferred to the magnet and reducing the low-temperature loss of the magnet, making the results of the low-temperature physical test more accurate and improving the reliability of the low-temperature physical performance test.

[0100] The thermal insulation base plate 70 can be fixedly connected to the ground to fix the support device 100 to the ground, so that in the process of placing the magnet on multiple support devices 100, and in the process of multiple support devices 100 supporting the magnet, the support device 100 as a whole is not easy to move, which can improve the stability of the support device 100 supporting the magnet, so as to improve the stability of the low-temperature physical property test. Of course, the thermal insulation base plate 70 can be detachably fixedly connected to the ground, for example, by a combination of one or more connection methods such as bolt connection and clamping, so that the thermal insulation base plate 70 can be detachably fixedly connected to the ground, so as to facilitate the removal of the support device 100 from the ground after the low-temperature physical property test of the supporting magnet is completed, so as to store the support device 100, facilitate subsequent recycling, increase the number of times the support device 100 can be used, and be more economical. For example Figure 2 and Figure 9 As shown, bolt holes are provided at the four corners of the insulation base plate 70, and the four corners of the insulation base plate 70 can be fixed to the ground by bolts to fix the position of the entire support device 100 on the ground. The support device 100 can be removed from the ground by subsequently removing the bolts of the insulation base plate 70.
