Technical Field

[0002] The use of magnetic confinement nuclear fusion to obtain energy is considered to be the most likely way to solve the energy crisis of mankind in the future. Among them, the Tokamak device is one of the most effective means to study magnetic confinement nuclear fusion energy. The main body of the device is mainly composed of divertor, blanket, vacuum chamber, dewar, cold shield and magnet. The main function of the cold shield is to provide an opaque thermal barrier between the low-temperature superconducting magnet and the components working in the low-temperature environment and other hot components. During the operation of the device, the heat load generated by thermal radiation or heat conduction on the superconducting magnet and the low-temperature components is reduced. Therefore, the installation of the cold shield is crucial to the operation of the entire device.

[0056] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0057] Reference below Figure 1-Figure 20 The following describes an assembly method of a fusion reactor bottom cold shield side plate 200 according to an embodiment of the first aspect of the present invention.

[0058] like Figure 1-Figure 20As shown, according to the assembly method of the bottom cold shield side panel 200 of a fusion reactor according to the first aspect of the embodiment of the present invention, the bottom cold shield side panel 200 is constructed as a ring formed by a plurality of side panels 2101, and the assembly method of the bottom cold shield side panel 200 of the fusion reactor includes: assembling a plurality of side panels 2101 into a sector 210; and assembling a plurality of sector segments 210 into a ring at the Dewar base 300 of the host hall 400.

[0059] In this embodiment, when the fusion reactor bottom cold shield side panel 200 is assembled, multiple side panels 2101 are assembled into a sector 210, and multiple sectors 210 are then assembled into a ring at the dewar base 300 of the main engine hall 400. Since the sector 210 is a part of the entire bottom cold shield side panel 200, the sector 210 is small in size and light in weight, so the sector 210 can be conveniently and easily hoisted into the relatively small space of the main engine hall 400 for assembly and installation, which greatly reduces the difficulty of hoisting and the risk of collision of the bottom cold shield side panel 200 during hoisting.

[0060] It is understandable that when the bottom cold shield side panel 200 is hoisted as a whole to the Dewar base 300, in order to make the position, installation angle, component size and status of the bottom cold shield side panel 200 meet the installation requirements, the entire bottom cold shield side panel 200 needs to pay attention to the offset of the hoisting position and the size and status of the components during the hoisting process, so a lot of adjustments are required, and after the entire bottom cold shield side panel 200 moves to a certain height above the Dewar base 300, a guide mechanism is required to ensure that the position of the ring body does not shift. The cost of the guide mechanism is high, which requires the use of more complex tooling equipment and larger hoisting equipment during the hoisting and installation of the bottom cold shield side panel 200, which makes the assembly cost of the bottom cold shield side panel 200 high, the adjustment cycle long, and the installation difficulty great.

[0061] In this embodiment, after a plurality of side panels 2101 are first formed into a sector 210, the plurality of sectors 210 are sequentially hoisted to the Dewar base 300 of the main engine hall 400 and assembled into a ring, so that when the bottom cold shield side panel 200 is installed on the Dewar base 300, the positions of the plurality of sectors 210 can be adjusted respectively, so that the plurality of sectors 210 can meet the need of precise ring formation. Since the weight and size of the sectors 210 are relatively small, the adjustment of the sectors 210 is relatively convenient, and the tooling equipment used can also be relatively simple, which greatly reduces the difficulty of installing the entire bottom cold shield side panel 200, greatly shortens the adjustment cycle during the assembly process, avoids the use of a costly guide mechanism, and makes the assembly cost of the bottom cold shield side panel 200 relatively low.

[0062] According to the assembly method of the fusion reactor bottom cold shield side panel 200 of an embodiment of the present invention, by assembling multiple side panels 2101 into a sector 210, and then assembling multiple sectors 210 into a ring at the dewar base 300 of the host hall 400, the bottom cold shield side panel 200 can well meet the assembly requirements in a small space during assembly, thereby greatly reducing the installation difficulty and assembly cost of the bottom cold shield side panel 200.

[0063] In some embodiments of the present invention, reference Figure 1-Figure 20 As shown, when multiple sectors 210 are assembled into a ring at the Dewar base 300 of the main engine hall 400, it can include: multiple sectors 210 are enclosed at the Dewar base 300 of the main engine hall 400 to form a ring with a gap; a side plate 2101 is assembled into the gap and assembled into a ring with multiple sectors 210.

[0064] In this embodiment, when multiple segments 210 are assembled into a ring at the Dewar base 300 of the main engine hall 400, multiple segments 210 are enclosed at the Dewar base 300 of the main engine hall 400 to form a ring with a gap. The gap formed can provide sufficient space for the multiple segments 210 during assembly and position adjustment, so that the multiple segments 210 can be easily adjusted in position to achieve the accurate size of the assembled ring. After a side plate 2101 is assembled to the gap, the operation of accurately forming a ring can be easily performed. For example, the side plate 2101 is assembled to the gap. When, in the circumferential direction of the bottom cold shield side panel 200, one side of the side panel 2101 can be accurately assembled with the sector 210 on one side of the notch first, and the gap space between the other side of the side panel 2101 and the sector on the other side of the notch due to errors in assembly, processing, etc. can be filled with a compensation strip to close the notch, thereby maintaining the precise ring size of multiple sectors 210 and the side panel 2101, so that the assembly method in which multiple sectors 210 are assembled into a complete ring with the side panel 2101 can well meet the needs of precise ring formation of the bottom cold shield side panel 200.

[0065] In one embodiment of the present invention, reference Figure 3 As shown, the number of sectors 210 may be greater than or equal to three and less than or equal to five.

[0066] In this embodiment, the number of sectors 210 is set to be greater than or equal to three and less than or equal to five, so that the number of sectors 210 in the entire bottom cold shield side panel 200 is sufficient, so that the weight and size of a single sector 210 can be small, so that the sectors 210 can be conveniently hoisted and adjusted, and the number of sectors 210 is below an appropriate number to avoid too many sectors 210 and a large number of hoisting times, which will cause a decrease in assembly efficiency, so that the bottom cold shield side panel 200 can be assembled more efficiently. For example, the number of sectors 210 can be three, four or five. For example, the number of sectors 210 is four, and the number of side panels 2101 in each sector 210 can be reasonably set according to actual needs, and is not specifically limited here.

[0067] In some embodiments of the present invention, reference Figure 1-Figure 20 As shown, when a plurality of sectors 210 are assembled into a ring at the Dewar base 300 of the main engine hall 400, the process may further include: the sectors 210 are moved from the center of the Dewar base 300 toward the bottom edge of the base for installation.

[0068] In this embodiment, after the sector 210 is hoisted to the main engine hall 400, the sector 210 is moved from the center of the Dewar base 300 toward the bottom edge of the base for installation. Specifically, the sector 210 can be hoisted to the Dewar base 300 along the center of the Dewar base 300, and then the sector 210 moves from the center position of the Dewar base 300 toward the bottom edge of the Dewar base 300 to reach the installation position. The sector 210 is installed after it moves to the installation position. In this way, interference and collision between the sector 210 and the Dewar base 300 can be avoided during the hoisting process, so that the sector 210 can be smoothly installed at the Dewar base 300.

[0069] It can be understood that when the entire bottom cold shield side panel 200 is pre-formed into a ring and then hoisted to the Dewar base 300 for installation, since the assembly gap between the ring-shaped bottom cold shield side panel 200 and the Dewar base 300 is small, in a specific example, the diameter of the bottom cold shield side panel 200 after forming a ring is 10.8m, and the inner diameter of the Dewar base 300 is 11m, then the final installation gap between the bottom cold shield side panel 200 and the Dewar base 300 is only 100mm, which makes the displacement deviation of the hoisting tool 20 have a great impact on the clearance between the bottom cold shield side panel 200 and the Dewar base 300. The relative position has a great influence, so there is a great risk of collision when the bottom cold shield side panel 200 is hoisted to the Dewar base 300 and moved to the installation position, and complex guide tooling is required for auxiliary assembly operations. In this embodiment, a single sector 210 can be conveniently moved from the center position of the Dewar base 300 toward the bottom edge position of the Dewar base 300 for installation, which has a large assembly movement space and does not require the aid of complex guide tooling, thereby making the installation of the bottom cold shield side panel 200 more convenient and greatly reducing the installation difficulty and assembly cost.

[0070] Reference below Figure 1-Figure 18 An assembly tool according to an embodiment of the second aspect of the present invention is described.

[0071] As reference Figure 1-Figure 18 As shown, as shown, the assembly tool according to the embodiment of the present invention is used to implement the assembly method of the fusion reactor bottom cold shield side plate 200 according to the first aspect of the present invention, and the assembly tool includes: an adjustment tool 10, a hoisting tool 20 and a hoist 30. The adjustment tool 10 is used to transport the side plate 2101; the hoisting tool 20 is used to fix the sector 210; the hoist 30 is suitable for hoisting the hoisting tool 20 and the sector 210 as a whole to the Dewar base 300 of the main engine hall 400.

[0072] In this embodiment, the assembly tooling includes an adjusting tooling 10, a lifting tooling 20 and a lifting device 30. The adjusting tooling 10 is used to transport the side panel 2101, the lifting tooling 20 is used to fix the fan segment 210, and the lifting device 30 is used to lift the lifting tooling 20 and the fan segment 210 as a whole to the Dewar base 300 of the main engine hall 400. The structure is simple and can well meet the assembly needs of the bottom cold screen side panel 200.

[0073] When the bottom cold screen side panel 200 is assembled and multiple side panels 2101 are assembled into a sector 210, the adjusting tool 10 can fix a side panel 2101 and transport the side panel 2101 to the lifting tool 20. Multiple adjusting toolings 10 respectively fix multiple side panels 2101 required for the sector 210 one by one and transport them to the lifting tool 20 and adjust their positions as a whole, so that the lifting tool 20 can form a complete sector 210 after fixing multiple side panels 2101.

[0074] After the lifting tool 20 fixes the sector 210, the lifting device 30 can lift the lifting tool 20 and the sector 210 as a whole into the main engine hall 400 and lift them to the Dewar base 300. The lifting device 30 can adjust the position of the lifting tool 20 and the sector 210 at the Dewar base 300 as needed, so that the sector 210 is gradually moved to the installation position for installation.

[0075] Since the overall weight and size of the adjusting tool 10 and the single side panel 2101 are relatively small, when the adjusting tool 10 and the single side panel 2101 need to be lifted as a whole, conventional small lifting equipment can meet the lifting needs of the adjusting tool 10 and the single side panel 2101 as a whole.

[0076] In this embodiment, the lifting device 30 hoists the lifting tool 20 and the fan segment 210 as a whole to the dewar base 300 of the main engine hall 400. The lifting tool 20 can play a good role in supporting and fixing the fan segment 210, so that the fan segment 210 maintains a stable structural state during the lifting process, thereby making the assembly of the bottom cold screen side panel 200 smoother.

[0077] In this embodiment, since the adjustment tool 10 only needs to transport a single side panel 2101, the lifting tool 20 only needs to support and fix a single sector 210, and the lifting device 30 only needs to lift a single sector 210 and the lifting tool 20, and the single side panel 2101 and the single sector 210 have a simple structure and a small overall weight and size, the assembly tool can easily and conveniently perform assembly and lifting operations on the bottom cold shield side panel 200 when in use, and there is no need to set up a large number of guide mechanisms and adjustment mechanisms for assembly operations. The structure is simple and the operating cost is low, so that the assembly cost of the bottom cold shield side panel 200 is low.

[0078] According to the assembly tooling of the embodiment of the present invention, an adjustment tooling 10, a lifting tooling 20 and a lifting device 30 are provided, which has a simple structure and low operating cost, and can well meet the assembly requirements of the bottom cold shield side panels 200, thereby reducing the assembly cost of the bottom cold shield side panels 200.

It can be understood that the multiple side panels 2101 in the sector 210 need to be connected in sequence to form a continuous sector 210 structure. In the extension direction of the sector 210, there is no gap between two adjacent side panels 2101. In this embodiment, the first fixing member 22 is fastened to the two adjacent side panels 2101, and the side panels 2101 can be assembled and fixed to the second tooling body 21 while meeting the needs of the sector 210 molding, thereby meeting the assembly requirements when the sector 210 is fixed to the lifting tooling 20. Specifically, when multiple side panels 2101 are assembled at the lifting tooling 20 to form the sector 210, the multiple side panels 2101 are moved to the corresponding installation positions of the lifting tooling 20 by adjusting the movement of the adjustment tooling 10, and the multiple side panels 2101 form a complete and continuous sector 210 structure. The first fixing member 22 then fastens the two adjacent side panels 2101, thereby fixing the entire sector 210 to the second tooling body 21.

The clamping portion 221 is fastened to the support beam of the second tooling body 21, and the fixing portion 222 is fastened to the flange of the side panel 2101. The structure is simple and the assembly is convenient, so that the side panel 2101 can be stably and reliably fixed to the second tooling body 21.

[0106] In this embodiment, the clamping portion 221 is provided with an oblong hole 2201 extending in the thickness direction of the side plate 2101, and the fastener passes through the oblong hole 2201 to fix the first fixing member 22 to the support beam, so that the first fixing member 22 can be conveniently adjusted in the thickness direction of the side plate 2101 relative to the support beam, so that the fixed position of the side plate 2101 on the hoisting fixture 20 in the thickness direction can be conveniently adjusted, so that each side plate 2101 in the sector 210 can be conveniently adjusted to form a sector 210 with more accurate overall size, so as to well meet the requirement of accurate ring formation of the bottom cold shield side plate 200. For example, two, three, four, etc. oblong holes 2201 can be provided, and multiple oblong holes 2201 are arranged at intervals in the up and down direction.

On the clamping portion 221, the clamping portion 221 needs to be provided with oblong holes 2201 in the direction in which the fastener is inserted to meet the need for the fastener to be inserted and fixed. For example, the fixing portion 222 can be fastened to the flange of the side plate 2101.

[0107] In one embodiment of the present invention, Fig.12 and Fig.15 As shown, part of the plurality of fixing members can be formed into a second fixing member 23, which is fixed to the second tooling body 21 and is tightly connected to the lower end of the side plate 2101. In this way, the lower side of the side plate 2101 can be more stably fixed to the second tooling body 21, and the fixing of the sector 210 on the hoisting tooling 20 can be more stably and reliably.

[0108] Further, the second fixing member 23 can be disposed at the bottom of the side plate 2101, so that the second fixing member 23 can provide good support for the side plate 2101, thereby allowing the sector 210 to be more stably fixed to the second tooling body 21. Exemplarily, the second fixing member 23 can be an L-shaped angle plate.

[0109] In one embodiment of the present invention, Fig.12 and Fig.16 as well as Fig.17As shown, the lifting tooling 20 may further include a center of gravity adjustment structure 24, which is disposed on the second tooling body 21 and includes: a counterweight 241. In a plane perpendicular to the up and down directions, the center of gravity adjustment structure 24 is configured to adjust the relative position of the counterweight 241 and the lifting tooling 20 to change and adjust the overall center of gravity of the lifting tooling 20 and the fan segment 210.

[0110] In this embodiment, the lifting tool 20 also includes a center of gravity adjustment structure 24. The counterweight 241 of the center of gravity adjustment structure 24 can change the relative position with the lifting tool 20 in a plane perpendicular to the up and down direction, so as to adjust the overall center of gravity of the lifting tool 20 and the fan segment 210. The structure is simple, and during the overall lifting of the lifting tool 20 and the fan segment 210, the overall center of gravity of the lifting tool 20 and the fan segment 210 can be adjusted to a suitable position so that the fan segment 210 maintains a stable posture for lifting, avoiding the situation where the center of gravity is deviated during the lifting process and the fan segment 210 tilts, so that each side panel 2101 in the fan segment 210 can maintain a stable position relationship and connection structure, so that the overall size of the fan segment 210 remains unchanged, so that when the fan segment 210 and the lifting tool 20 are lifted as a whole to the Dewar base 300 of the main engine hall 400, the fan segment 210 and the lifting tool 20 can fall smoothly and smoothly to the bottom of the Dewar base 300 and adjust and move their positions.

[0111] In some examples of the present invention, Fig.17 As shown, there may be a plurality of counterweight members 241 , and the plurality of counterweight members 241 are arranged at intervals on the second tooling body 21 .

[0112] In the present embodiment, a plurality of counterweights 241 are provided, and the plurality of counterweights 241 are arranged at intervals on the second tooling body 21. When the center of gravity of the lifting tooling 20 and the sector 210 is adjusted as a whole, the plurality of counterweights 241 can cooperate to adjust the center of gravity more flexibly and conveniently, making the adjustment of the center of gravity of the lifting tooling 20 and the sector 210 as a whole more efficient.

[0113] In some examples of the present invention, Fig.12 and Fig.17 As shown, the center of gravity adjustment structure 24 may also include: a movable plate 242, a guide rail 243 and a driving assembly. The number of movable plates 242 is two, and the two movable plates 242 are arranged at intervals in the first direction. A plurality of counterweights 241 may be placed on the movable plate 242. The bottom of the movable plate 242 is provided with a guide groove that slides with the guide rail 243. The guide rail 243 is provided on the second tooling body 21 and extends along the second direction. The driving assembly is suitable for driving the movable plate 242 to move along the guide rail 243.

[0114] In this embodiment, the center of gravity adjustment structure 24 is provided with two movable plates 242 arranged at intervals in the first direction, and a counterweight 241 is provided on the movable plate 242. The movable plate 242 is movable in the second direction along the guide rail 243. The structure is simple and can well meet the adjustment needs of the center of gravity adjustment structure 24. When the center of gravity of the lifting fixture 20 is adjusted, the driving assembly drives the two movable plates 242 to move in the second direction respectively, so that the relative positions of the counterweights 241 on the two movable plates 242 in the horizontal direction change, thereby changing the overall weight distribution of the lifting fixture 20 and the sector 210, so that the center of gravity is adjusted. For example, the number of counterweights 241 on the two movable plates 242 can be flexibly set as needed to meet the center of gravity adjustment needs under actual working conditions. For example, the number of guide rails 243 cooperating with the movable plate 242 can be set to be multiple, so that the movable plate 242 can be connected more stably.

[0116] In this embodiment, the driving assembly is provided with a rotating handle 244 and a driving screw 245 to drive the movable plate 242, which has a simple structure and is easy to operate. When the center of gravity of the lifting tool 20 and the sector 210 is adjusted as a whole, the operator can operate the rotating handle 244 to rotate the driving screw 245, so that the movable plate 242 can move along the guide rail 243 and drive the counterweight 241 to move.

In this way, the counterweight 241 can be stably placed on the movable plate 242, and the counterweight 241 on the movable plate 242 can be conveniently increased or decreased as needed, making it more convenient to adjust the center of gravity of the hoisting tool 20 and the sector 210 as a whole.

[0118] In one embodiment of the present invention, Fig.12 , Fig.16 and Fig.18As shown, the lifting tooling 20 may further include: a plurality of support seats 26 and a plurality of fourth adjustment mechanisms 25, the plurality of support seats 26 are arranged at intervals, the plurality of fourth adjustment mechanisms 25 are arranged one-to-one with the plurality of support seats 26, the support seats 26 support the second tooling body 21 through the fourth adjustment mechanism 25, and the fourth adjustment mechanism 25 is configured to drive the second tooling body 21 to rise and fall.

[0119] In this embodiment, the lifting tool 20 also includes a plurality of support seats 26 arranged at intervals, and a fourth adjustment structure is provided on each support seat 26 and connected to the second tool body 21. The fourth adjustment mechanism 25 is used to drive the second tool body 21 to rise and fall. The structure is simple, so that the height of the segment 210 can be conveniently adjusted when it is assembled at the Dewar base 300, so that the positions of the plurality of segments 210 can be more accurate, and the plurality of segments 210 can be more accurately assembled into a ring, which well meets the assembly needs of the bottom cold shield side panel 200.

[0120] When the height of the sector 210 needs to be adjusted, multiple fourth adjustment mechanisms 25 cooperate to adjust the height of the second tooling body 21, so that the height position of the sector 210 fixed on the second tooling body 21 can be well adjusted. For example, the number of the fourth adjustment mechanisms 25 can be two, three, four, six, eight, twelve, etc. Optionally, the number of the fourth adjustment mechanisms 25 is eight, and eight support seats 26 are correspondingly provided.

[0121] In some examples of the present invention, the number of the fourth adjustment mechanisms 25 may be at least four. In this way, there may be a sufficient number of the fourth adjustment mechanisms 25 to stably and reliably adjust the height of the entire hoisting tool 20, so that the sector 210 can be stably adjusted in height. For example, the number of the fourth adjustment mechanisms 25 may be four, six, eight, twelve, fourteen, and so on.

The adjusting bolt 253 is threadedly connected to the adjustment plate 251 and abuts against the support seat 26 in the up and down directions.

[0123] In this embodiment, the fourth adjustment mechanism 25 is provided with an adjustment plate 251, a mounting screw 252 and an adjustment bolt 253, which has a simple structure and is convenient for fixing the second tooling body 21 to the support seat 26. Multiple adjustment bolts 253 can be used to conveniently adjust the height of the second tooling body 21, thereby meeting the adjustment needs of the sector 210.

[0124] When the fourth adjustment mechanism 25 is height-adjusted, the operator screws the adjustment bolt 253 and the fixing nut 254, so that the adjustment plate 251 can move away from or close to the support seat 26 in the up-down direction under the action of the adjustment bolt 253, thereby changing the height position of the second tooling body 21, and further adjusting the height position of the sector 210. Exemplarily, the hoisting tooling 20 can be a symmetrical structure in the second direction, so that the hoisting tooling 20 can be more conveniently and easily adjusted to a stable posture when the center of gravity is adjusted.

[0125] The following will refer to Figure 1-Figure 18 An assembly tool according to a specific embodiment of the present invention is described.

A plurality of lifting ears 211 can be provided on the second tooling body 21 to facilitate the lifting and assembly of the lifting device 30.

[0129] Reference below Figure 1-Figure 20 The assembly method of the fusion reactor bottom cold shield side plate 200 according to the present invention is described.

[0130] like Figure 1-Figure 20 As shown, when the bottom cold screen side panel 200 is assembled, multiple side panels 2101 are pre-assembled into four sectors 210 in the pre-assembly hall. Specifically, the adjustment tooling 10 fixes the side panel 2101 through the first adjustment mechanism 12 and the second adjustment mechanism 13. The first adjustment mechanism 12 cooperates with the second adjustment mechanism 13 and the third adjustment mechanism 14 to adjust the side panel 2101 in the height direction and the thickness direction of the side panel 2101, so that the subsequent multiple side panels 2101 can be accurately positioned and assembled, and the multiple side panels 2101 are shipped to each adjustment tooling 10 in turn.

[0131] Multiple adjustment tools 10 transport multiple side panels 2101 to the lifting tool 20 and move the multiple side panels 2101 to corresponding positions fixed with the lifting tool 20, so that the multiple side panels 2101 cooperate to form a continuous and complete sector 210. The lifting tool 20 stably fixes the multiple side panels 2101 to the lifting tool 20 through multiple first fixing members 22 and second fixing members 23.

The lifting tool 30 lifts the segment 210 and the lifting tool 20 as a whole into the main engine hall 400 and gradually transports them to the Dewar base 300, so that the lifting tool 20 and the segment 210 gradually move from the center position of the Dewar base 300 toward the bottom edge position of the Dewar base 300 until reaching the installation position of the segment 210, the lifting tool 30 can be loosened, so that the lifting tool 20 is fixed to the Dewar base 300 through the support seat 26, and the lifting tool 20 can adjust the segment 210 in the height direction and radial direction through the first fixing member 22 and the fourth adjustment mechanism 25, so that the segment 210 moves into place.

[0133] The hoist 30 hoists the four sectors 210 and the hoisting tool 20 to the Dewar base 300 in turn and adjusts the height and the like. The multiple sectors 210 are assembled and fixed at the Dewar base 300 to form a ring with a gap. A conventional small hoist can hoist the last side panel 2101 and the adjustment tool 10 to the Dewar base 300 and move the side panel 2101 to the gap position. The side panel 2101 and the four sectors 210 are adjusted in position and a compensation strip is set between one side of the side panel and an adjacent sector to fill the gaps and spacings caused by errors such as processing and assembly, so that the multiple sectors are assembled and connected to the side panels to form a complete and precise ring structure of the bottom cold shield side panel 200, so that the bottom cold shield side panel 200 and the Dewar base 300 form a good assembly relationship.

[0134] In the process of assembling the bottom cold shield side panel 200 into a ring in this embodiment, the assembly tooling used is simple and can be well controlled and adjusted. By first forming the side panel 2101 into a plurality of sectors 210, and then hoisting the plurality of sectors 210 to the Dewar base 300 of the main engine hall 400 for assembly into a ring, the installation operation of the bottom cold shield side panel 200 in a compact space can be well adapted, thereby greatly reducing the assembly difficulty and assembly cost of the bottom cold shield side panel 200.
