Description

Technical Field

[0001] This invention relates to the field of nuclear fusion technology, and in particular to a device for fixing pre-assembled nuclear fusion components. Background Technology

[0002] During the overall construction of the tokamak nuclear fusion device, the components are cut and divided along the circumference to facilitate manufacturing and final assembly. Currently, based on the division of the vacuum chamber, the entire structure is divided into eight sectors, each corresponding to a cold screen and a toroidal field magnet. The vacuum chamber, cold screen, and toroidal field magnet for each sector are then assembled and assembled before entering the main control room for loop-locking.

[0003] During the pre-assembly of the vacuum chamber, cold screen, and toroidal field magnet in the external pre-assembly hall, problems in each sector during assembly can be detected. After pre-assembly and passing measurement and inspection, the pre-assembled components of the vacuum chamber, cold screen, and toroidal field magnet are then hoisted as a whole and placed in the main unit hall for vacuum chamber loop-locking preparation. The overall hoisting of the vacuum chamber, cold screen, and toroidal field magnet involves significant weight, and there are high dimensional control requirements between them. Therefore, ensuring the high-precision relative positions of the vacuum chamber, cold screen, and toroidal field magnet during the overall hoisting process, and avoiding collisions and damage to the three components, has become one of the urgent problems to be solved.

[0045] The fixing device 100 of the nuclear fusion pre-assembly assembly of this invention is used to fix the relative positions of the magnet 200 and the vacuum chamber 300 of the nuclear fusion device. After the vacuum chamber 300, the cold screen, and the magnet 200 are assembled as a whole, the whole assembly needs to be hoisted into the main unit hall. During the hoisting process, there is a certain gap between the vacuum chamber 300 and the magnet 200. Since the cold screen is fixed on the vacuum chamber 300, only the relative positions of the magnet 200 and the vacuum chamber 300 need to be fixed during the assembly process. The fixing device 100 of the nuclear fusion pre-assembly assembly of this invention can fix the vacuum chamber 300 and the magnet 200, so that the gap between the vacuum chamber 300 and the magnet 200 will not disappear, thus avoiding collisions and ensuring the reliability of the vacuum chamber 300 and the magnet 200 during suspension and movement.

[0046] The following is for reference. Figures 1-9 This describes a fixing device 100 for a nuclear fusion pre-assembled component according to an embodiment of the present invention.

[0047] like Figure 1 and Figure 2As shown, the fixing device 100 for the nuclear fusion pre-assembly assembly of this embodiment includes a magnet connecting assembly 10, a vacuum chamber connecting assembly 20, and a beam connecting assembly 30. The magnet connecting assembly 10 includes a first beam 11 and a magnet connecting portion 12. The first beam 11 extends along a first direction, and the magnet connecting portion 12 is disposed on the first beam 11. The vacuum chamber connecting assembly 20 is spaced apart from the magnet connecting assembly 10 along a second direction and includes a second beam 21 and a vacuum chamber connecting portion 22. The second beam 21 extends along the first direction, and the vacuum chamber connecting portion 22 is disposed on the second beam 21, wherein the second direction is perpendicular to the first direction. The beam connection assembly 30 is located at both ends of the second beam 21 in the first direction and connects to the first beam 11. It includes a first connector 31, a second connector 32 and an elastic energy storage component 33. The first connector 31 is movably connected to the second connector 32 and is detachably connected to the first beam 11. The second connector 32 is detachably connected to the second beam 21. One end of the elastic energy storage component 33 is movably connected to the first connector 31 and the other end is movably connected to the second connector 32.

[0048] In the above technical solution, the first beam 11 and the second beam 21 can refer to beam structures, and can be, but is not limited to, square steel structures, I-beam structures, etc. The first beam 11 and the second beam 21 can refer to straight beams, or curved or arc-shaped beams. When the first beam 11 and the second beam 21 are curved or arc-shaped beams, the first beam 11 and the second beam 21 extend approximately along a first direction.

[0049] The magnet connecting part 12 can refer to a structure fixedly connected to the magnet 200, and one or more can be provided on the first beam 11. The vacuum chamber connecting part 22 can refer to a structure fixedly connected to the vacuum chamber 300, and one or more can be provided on the second beam 21. The magnet connecting part 12 and the vacuum chamber connecting part 22 can be, but are not limited to, a bolt connection structure, a pin connection structure, a snap-fit ​​structure, etc. The structures of the magnet connecting part 12 and the vacuum chamber connecting part 22 can be the same or different.

[0050] The first direction and the second direction can refer to two mutually perpendicular directions. Optionally, refer to... Figure 2 The first direction can be left or right, and the second direction can be front or back.

[0051] The first connector 31 and the second connector 32 can refer to components that serve a connecting function, and can be, but are not limited to, plate structures, beam structures, column structures, etc. Optionally, refer to... Figure 2Both the first connecting member 31 and the second connecting member 32 can be beam structures. The movable connection direction between the first connecting member 31 and the second connecting member 32 can be, but is not limited to, hinged joints, ball joints, etc. The detachable connection method between the first connecting member 31 and the first beam 11, and the detachable connection method between the second connecting member 32 and the second beam 21, can be, but is not limited to, bolted connections, snap-fit ​​connections, riveting, etc. Optionally, refer to... Figure 2 The first connecting piece 31 can be connected to the first beam 11 by bolts, and the second connecting piece 32 can also be connected to the second beam 21 by bolts.

[0052] The elastic energy storage element 33 can refer to a structure or component capable of elastically compressing and storing energy. Optionally, the elastic energy storage element 33 can be a spring structure. The elastic contraction displacement of the elastic energy storage element 33 is small and can be less than the gap between the magnet 200 and the vacuum chamber 300.

[0053] In the fixing device 100 for the nuclear fusion pre-assembly assembly described above, the magnet connecting part 12 can be connected to the magnet 200, for example, the magnet connecting part 12 is fixedly connected to the outer coil box of the magnet. The vacuum chamber connecting part 22 can be connected to the vacuum chamber 300, for example, the vacuum chamber connecting part 22 is connected to the hole inside the vacuum chamber 300. Then, the beam connecting assembly 30 is connected to the first beam 11 and the second beam 21. Since the first connecting member 31 and the second connecting member 32 are movably connected, the first connecting member 31 and the second connecting member 32 have good degrees of freedom, which facilitates the connection of the first beam 11 and the second beam 21, and also reduces the weight of individual components and reduces the installation difficulty. The elastic energy storage member 33 connects the first connecting member 31 and the second connecting member 32, which can also improve the overall rigidity of the beam connecting assembly 30, thereby improving the overall rigidity of the fixing device 100 for the nuclear fusion pre-assembly assembly. Furthermore, during suspension and movement, since the first connecting member 31 and the second connecting member 32 are movably connected, and the elastic energy storage member 33 is also movably connected to the first connecting member 31 and the second connecting member 32, the elastic energy storage member 33 can absorb impact loads and effectively suppress hoisting vibrations to ensure the safety of the magnet 200 and the vacuum chamber 300.

[0054] The fixing device 100 for the nuclear fusion pre-assembly assembly according to an embodiment of the present invention forms a rigid structure through the magnet connecting assembly 10, the vacuum chamber connecting assembly 20, and the beam connecting assembly 30, thereby constraining the gap between the magnet 200 and the vacuum chamber 300, ensuring high positional accuracy between the magnet 200 and the vacuum chamber 300, and preventing collision damage during hoisting. The elastic energy storage component 33 can absorb impact loads during suspension and movement with a small amplitude, which helps improve the stability of the suspension and movement of the magnet 200 and the vacuum chamber 300. Moreover, the beam connecting assembly 30 has a certain degree of freedom, which is conducive to better adapting the connection between the magnet connecting assembly 10 and the magnet 200, and the connection between the vacuum chamber connecting assembly 20 and the vacuum chamber 300, thus reducing the installation difficulty.

[0055] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, there are two magnet connecting parts 12 along the first direction, and the magnet connecting parts 12 include a first support beam 121 and a magnet fastener 122. The first support beam 121 extends along a third direction, and the third direction, the second direction and the first direction are perpendicular to each other. The magnet fastener 122 is provided on the first support beam 121, and there are multiple magnet fasteners 122 along the third direction.

[0056] Optionally, the magnet connecting portions 12 may be located at both ends of the first beam 11 in a first direction. Optionally, the two magnet connecting portions 12 may be spaced a certain distance from both ends of the first beam 11 in the first direction, simply spaced apart along the first direction. It is understood that by providing two magnet connecting portions 12, the number of connection points with the magnet 200 can be increased, thereby improving the reliability of fixing the magnet 200.

[0057] The first supporting beam 121 can be, but is not limited to, a plate structure, a pipe structure, or a column structure, etc., and can be a hollow structure or a solid structure. Optionally, the first supporting beam 121 can be a square steel beam. Optionally, the first supporting beam 121 can also be an I-beam. As an example, a third-party reference can be made. Figure 2 The first support beam 121 extends along the third direction, that is, the first support beam 121 and the first beam body 11 are perpendicularly connected. Thus, the connection between the first support beam 121 and the first beam body 11 can form a T-shaped structure or a cross-shaped structure, which can improve the overall structural rigidity and enhance the overall support stability and reliability of the fixing device 100 of the nuclear fusion pre-installed components.

[0058] The magnet fastener 122 can be, but is not limited to, bolts, studs, pins, or snap-fit ​​blocks, etc. Optionally, such as... Figure 2As shown, the magnet fastener 122 is a bolt group, and two bolts are arranged along the third direction on the first support beam 121. Each bolt group includes two rows spaced apart along the first direction, and multiple bolts are arranged along the third direction in each row.

[0059] In the above technical solution, the above structure can improve the structural strength of the magnet connecting part 12 and increase the connection position with the magnet 200, which can improve the connection strength and connection reliability between the magnet connecting part 12 and the magnet 200, and is conducive to fixing the magnet 200 more firmly.

[0060] In some embodiments of the present invention, such as Figure 2 As shown, the two ends of the first support beam 121 in the third direction protrude relative to the first beam body 11. This arrangement minimizes obstruction at the two ends of the first support beam 121 in the third direction, facilitating connection between the magnet connecting part 12 and the magnet 200, reducing connection difficulty, and improving installation efficiency. Furthermore, this structure also shifts the center of gravity of the magnet connecting assembly 10 upwards, closer to the center of gravity of the magnet 200, which helps improve the stability of the magnet 200 during suspension and movement.

[0061] In some embodiments of the present invention, such as Figures 2 to 4 As shown, there are two vacuum chamber connection parts 22 along the first direction. The vacuum chamber connection part 22 includes a second support beam 221 and a vacuum chamber fastener 222. The second support beam 221 extends along a third direction. The third direction, the second direction and the first direction are perpendicular to each other. The vacuum chamber fastener 222 is provided on the second support beam 221 and there are multiple fasteners along the third direction.

[0062] Optionally, the vacuum chamber connection portion 22 can be located at both ends of the second beam 21 in the first direction. Optionally, the two vacuum chamber connection portions 22 are spaced a certain distance from the two ends of the second beam 21 in the first direction, simply spaced apart along the first direction. It is understood that by providing two vacuum chamber connection portions 22, the number of connection points with the vacuum chamber 300 can be increased, thereby improving the reliability of fixing the vacuum chamber 300.

[0063] The second support beam 221 can be, but is not limited to, a plate structure, a pipe structure, or a column structure, etc., and can be a hollow structure or a solid structure. Optionally, the second support beam 221 can be a square steel beam. Optionally, the second support beam 221 can also be an I-beam. As an example, a third-party reference can be made. Figure 2 The second support beam 221 extends along the third direction, that is, the second support beam 221 is perpendicularly connected to the second beam body 21. Thus, the connection between the second support beam 221 and the second beam body 21 can form a T-shaped structure or a cross-shaped structure, which can improve the overall structural rigidity and enhance the overall support stability and reliability of the fixing device 100 of the nuclear fusion pre-installed components.

[0064] The vacuum chamber fastener 222 can be, but is not limited to, bolts, studs, pins, or snap-fit ​​blocks, etc. There can be one, two, three, etc., vacuum chamber fastener 222 along a third direction. Optionally, refer to... Figure 4 The vacuum chamber fastener 222 can be set to two along a third direction.

[0065] In the above technical solution, the above structure can improve the structural strength of the vacuum chamber connection part 22 and increase the connection position with the vacuum chamber 300, which can improve the connection strength and connection reliability between the vacuum chamber connection part 22 and the vacuum chamber 300, and help to fix the vacuum chamber 300 more firmly.

[0066] In some embodiments of the present invention, such as Figure 5 As shown, the vacuum chamber fastener 222 includes a base 2201, an adjusting block 2202, a joint shaft 2203, an adapter 2204, and a connector 2205. The base 2201 is connected to the second support beam 221. The adjusting block 2202 is adjustablely mounted on the base 2201. The joint shaft 2203 is adjustablely mounted on the adjusting block 2202. The adapter 2204 is hinged to the joint shaft 2203. The connector 2205 is mounted on the adapter 2204.

[0067] Adjustment block 2202 can be, but is not limited to, plate-like structures, block-like structures, rod-like structures, etc., for example, refer to Figure 5 Adjustment block 2202 is an adjustment plate. Joint shaft 2203 can be, but is not limited to, a threaded adjusting rod, a turnbuckle, etc. Adapter seat 2204 can be, but is not limited to, a hinge seat, etc.

[0068] In the above technical solution, the adjusting block 2202, the joint shaft 2203, and the adapter 2204 are all adjustable, which enables the vacuum chamber fastener 222 to have a high degree of freedom as a whole. The position of the plug 2205 can be flexibly adjusted to better match the holes inside the vacuum chamber 300, thereby reducing assembly difficulty and improving assembly efficiency.

[0069] In some embodiments of the present invention, such as Figure 5 As shown, the adjustment block 2202 is adjustable in position relative to the base 2201 along the second direction and can be rotated around the first direction; the joint shaft 2203 is retractable relative to the adjustment block 2202 in a direction perpendicular to the adjustment block 2202; the adapter 2204 is adjustable in rotation around the joint shaft 2203.

[0070] As an example, the first direction can be Figure 5 The left and right directions, the second direction can be Figure 5 The front and back directions.

[0071] In the above technical solution, the adjusting block 2202 has two degrees of freedom relative to the base 2201, the joint shaft 2203 has one degree of freedom relative to the adjusting block 2202, and the adapter 2204 has one degree of freedom relative to the joint shaft 2203. As a result, the vacuum chamber fastener 222 has a higher degree of freedom as a whole, and can adapt to the arc-shaped wall structure inside the vacuum chamber 300. It can better match the holes inside the vacuum chamber 300 and better fix the vacuum chamber 300.

[0072] In some embodiments of the present invention, such as Figure 5 As shown, the base 2201 has adjustment holes 2201a at both ends in the first direction, and the adjustment holes 2201a extend along the second direction. The adjustment block 2202 has adjustment bolts 2206 at both ends in the first direction, and the adjustment bolts 2206 pass through the adjustment holes 2201a. The base 2201 is provided with threaded fasteners 2207, which are arranged along the second direction and one end abuts against the adjustment block 2202.

[0073] It is understandable that by loosening the adjusting bolt 2206, the adjusting block 2202 can be adjusted along the adjusting hole 2201a, and then the tilt angle of the adjusting block 2202 can be adjusted by the threaded fastener 2207. Finally, tightening the adjusting bolt 2206 can fix the position of the adjusting block 2202. In this way, the position of the adjusting block 2202 relative to the base 2201 in the second direction and the rotation angle around the first direction can be adjusted. This adjustment structure is relatively simple and can improve the reliability of adjustment.

[0074] Optionally, the threaded fastener 2207 can be, but is not limited to, bolts, threaded rods, etc.

[0075] In some embodiments of the present invention, such as Figure 5 As shown, the connector 2205 includes a base plate 22051 and a columnar member 22052. The base plate 22051 is connected to the adapter 2204 and is inclined relative to the adapter 2204 toward the center of the fixing device 100 for nuclear fusion pre-assembly. The columnar member 22052 is disposed on the base plate 22051.

[0076] In the above technical solution, the base plate 22051 is tilted relative to the adapter 2204 towards the center of the fixing device 100 for nuclear fusion pre-assembly components. This allows the plug 2205 to adapt to the arc-shaped wall inside the vacuum chamber 300 before the vacuum chamber fastener 222 is adjusted, which is more conducive to the matching of the column 22052 with the internal holes of the vacuum chamber 300.

[0077] Optionally, one or more columnar members 22052 may be provided on the base plate 22051. For example, refer to Figure 5Two columnar components 22052 are provided on the base plate 22051. The columnar components 22052 can be, but are not limited to, pins, sleeves, etc.

[0078] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the first connector 31 is bent relative to the first beam 11 toward the side away from the center of the fixing device 100 of the nuclear fusion pre-assembly assembly, and the second connector 32 is bent relative to the second beam 21 toward the side away from the center of the fixing device 100 of the nuclear fusion pre-assembly assembly, and is hinged to the first connector 31 around a third direction; one end of the elastic energy storage component 33 is hinged to the first connector 31 around a third direction, and the other end is hinged to the second connector 32 around a third direction.

[0079] It is understandable that after the first connector 31 and the second connector 32 are connected, the whole is in a V-shape or a horn shape, and the opening between the first connector 31 and the second connector 32 faces the center of the fixing device 100 of the nuclear fusion pre-installed component. With this structure, when the magnet 200 and the vacuum chamber 300 are subjected to impact loads during suspension and movement, the first connector 31 and the second connector 32 can rotate relative to each other and allow the elastic energy storage component 33 to absorb the impact loads. This can enhance the overall ability of the beam connection assembly 30 to bear and absorb impact loads and improve the reliability of the relative position between the magnet 200 and the vacuum chamber 300.

[0080] Secondly, the first connector 31 and the second connector 32 are hinged together, and the elastic energy storage component 33 is hinged together with the first connector 31 and the second connector 32. This allows the beam connection assembly 30 to have a certain degree of mobility while also having good rigidity. Since the first beam 11 and the second beam 21 are connected through the beam connection assembly 30, this method helps to give the fixing device 100 of the nuclear fusion pre-installed component good rigidity, which can better fix the magnet 200 and the vacuum chamber 300, and maintain the stability and reliability of the gap between the magnet 200 and the vacuum chamber 300.

[0081] In some embodiments of the present invention, such as Figure 4 As shown, a plane perpendicular to the first direction is formed. The extension directions of the first connector 31 and the second connector 32 in the orthographic projection of the plane are set at an angle to the second direction. The elastic energy storage member 33 in the orthographic projection of the plane extends along the extension direction.

[0082] Reference Figure 4 The extension direction of the first connector 31 and the second connector 32 in the orthographic projection of the plane can be... Figure 4 The first extension line a, the second direction can be with Figure 4 The second extension line b is in the same direction, that is, there is an angle between the first extension line a and the second extension line b.

[0083] In the above technical solution, after the fixing device 100 of the nuclear fusion pre-installed component fixes the magnet 200 and the vacuum chamber 300, regardless of whether it is subjected to impact loads in the first direction, the second direction or the third direction, the impact loads can be absorbed by the elastic energy storage component 33 along the first connector 31 and the second connector 32, thereby suppressing impact loads in different directions and improving the stability and reliability of the magnet 200 and the vacuum chamber 300 during suspension and movement.

[0084] In some embodiments of the present invention, the extending directions of the first connector 31 and the second connector 32 in the orthographic projection of the plane are configured to be parallel or substantially parallel to the center of gravity of the magnet 200 and the vacuum chamber 300.

[0085] Understandably, during normal assembly, the centers of gravity of magnet 200 and vacuum chamber 300 are not at the same horizontal level. The above solution allows magnet connecting assembly 10 to connect magnet 200 and vacuum chamber connecting assembly 20 to connect vacuum chamber 300. The beam connecting assembly 30 can then keep the centers of gravity of magnet 200 and vacuum chamber 300 in the expected position, which helps to improve the assembly stability and reliability of magnet 200 and vacuum chamber 300.

[0086] In some embodiments of the present invention, such as Figure 2 , Figure 3 and Figure 6 As shown, the fixing device 100 for the nuclear fusion pre-loading component includes a central pre-loading component 40. The central pre-loading component 40 includes a support frame 41 and an adjustable connector 42. The support frame 41 is connected to the middle position of the second beam 21. The adjustable connector 42 is adjustable in length along the second direction, and one end is hinged to the support frame 41 and the other end is hinged to the first beam 11.

[0087] The adjustable connector 42 can be, but is not limited to, an adjustment mechanism consisting of a turnbuckle, a sleeve, and a double lead screw.

[0088] Understandably, the central preload assembly 40 connects the first beam 11 and the second beam 21. Working in conjunction with the beam connection assembly 30, it further enhances the overall structural rigidity of the fusion pre-assembly fixing device 100, improving the reliability of fixing the magnet 200 and the vacuum chamber 300. The adjustable connector 42 has an adjustment function, thus allowing adjustment of the preload force of the central preload assembly 40 between the first beam 11 and the second beam 21, better supporting the first beam 11 and the second beam 21.

[0089] In some embodiments of the present invention, such as Figure 6 and Figure 7As shown, the adjustable connector 42 includes a threaded sleeve 421, a screw 422, and a spherical bearing 423. Both ends of the threaded sleeve 421 are threadedly connected to the screw 422 in the length direction. Each screw 422 is connected to a spherical bearing 423. One of the two spherical bearings 423 is connected to the support frame 41 through a hinge lug 43, and the other is connected to the first beam 11 through a hinge lug 43.

[0090] In the above technical solution, by rotating the threaded sleeve 421 and the screw 422 relative to each other, the distance between the two spherical bearings 423 can be adjusted, thereby achieving an adjustable overall length of the adjustable connector 42. The two spherical bearings 423 are connected to the support frame 41 and the first beam 11 through hinge lugs 43, which provides a high degree of freedom and facilitates connection with the first beam 11 and the second beam 21.

[0091] In some embodiments of the present invention, such as Figure 6 As shown, at least two adjustable connectors 42 are provided along the first direction. It is understood that increasing the number of adjustable connectors 42 enhances the reliability and stability of the connection between the support frame 41 and the first beam 11. Secondly, this approach also reduces the weight of a single adjustable connector 42. Since the nuclear fusion device is relatively large in size and volume, the adjustable connectors 42 are also relatively large in weight and size. Reducing the weight of a single adjustable connector 42 can lower the installation difficulty and improve construction efficiency.

[0092] In some embodiments of the present invention, the central preload assembly 40 further includes a force detection element, which is located at the force-bearing position between the adjustable connector 42 and the second beam 21, or at the force-bearing position between the adjustable connector 42 and the first beam 11.

[0093] Force detection components can refer to detection components or devices such as sensors that can detect force. For example, a force detection component can be a strain gauge. As an example, the force-bearing positions of the adjustable connector 42 and the second beam 21, as well as the force-bearing positions of the adjustable connector 42 and the first beam 11, can both refer to the rotational positions of the spherical bearing 423 and the hinge lug 43.

[0094] In the above technical solution, the force detection device can detect the force between the adjustable connector 42 and the support frame 41. This allows for real-time monitoring of the force on the first beam 11 and the second beam 21 via a remote receiving device or platform, enabling timely adjustment of the speed of the magnet 200 and the vacuum chamber 300 during suspension and movement. This improves the safety and reliability of the magnet 200 and the vacuum chamber 300 during suspension and movement.

[0095] In some embodiments of the present invention, such as Figure 8 and Figure 9As shown, the elastic energy storage component 33 includes a first spring shaft 331, a spring 332, a pressure plate 333, a pad 334, a sleeve flange 335, a limiting flange 336, and a second spring shaft 337. The first spring shaft 331 is hinged to the first connecting member 31. The pressure plate 333 is disposed on the first spring shaft 331. There are at least two springs 332, which are sleeved on the first spring shaft 331 and located on the side of the pressure plate 333 away from the first connecting member 31. A pad 334 is provided between at least one pair of adjacent springs 332. The sleeve flange 335 is sleeved on the first spring shaft 331. The sleeve flange 335 and the limiting flange 336 are connected and together form a limiting space 33a. The second spring shaft 337 is connected to the limiting flange 336 and is hinged to the second connecting member 32. The first spring shaft 331 is provided with a first limiting ring 331a and a second limiting ring 331b. The first limiting ring 331a abuts against the pressure plate 333, and the second limiting ring 331b is located within the limiting space 33a.

[0096] In the above technical solution, the elastic energy storage component 33 adopts the above structure and can absorb impact loads through compression by spring 332. The structure is simple and the working reliability is high.

[0097] Optionally, in the axial direction of the first spring shaft 331, the size of the limiting space 33a is smaller than the size of the gap between the magnet 200 and the vacuum chamber 300. The axial direction of the first spring shaft 331 can be referenced... Figure 9 In the front and back directions, this method can prevent the first spring shaft 331 from impacting due to large displacement, and also prevent the magnet 200 and the vacuum chamber 300 from colliding during the absorption of impact loads.
