Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without any creative effort shall fall within the scope of protection of the present invention.

The terms "first", "second", etc. in the description and claims of this invention or the above drawings are used to distinguish different objects and are not used to describe a specific order or primary-secondary relationship.

[0027] In the description of this invention, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "joined", "attached" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in this invention can be understood according to specific situations.

[0028] The term "and / or" in this invention is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this invention generally represents an "or" relationship between the associated objects before and after.

[0029] In the embodiments of this invention, the same reference numerals represent the same components, and for the sake of brevity, in different embodiments, the detailed descriptions of the same components are omitted. It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of this invention shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only for illustrative purposes and should not constitute any limitation to this invention.

[0030] The "plurality" mentioned in this invention refers to two or more (including two).

[0031] The following Figures 1 to 12 is used to describe the in-vessel feeder assembly tooling 100 and method of this invention.

[0032] As Figure 1 shown, the in-vessel feeder 200 of the fusion reactor includes a housing 201 and a cable 203 passing through the housing 201, and the housing 201 has a first group of target seats 10.

[0033] Specifically, the cable 203 in the feeder 200 in the fusion reactor includes a superconducting cable, which has poor bendability and is prone to cracks when bent, thereby reducing the performance. By providing a housing 201, the superconducting cable can be positioned and fixed so that the superconducting cable is not easily bent or deformed, thereby ensuring the performance of the superconducting cable, and protecting the superconducting cable so that the superconducting cable is not easily damaged. In addition, the cable 203 in the feeder 200 in the fusion reactor can also include a cooling pipe and a signal pipe. The cooling pipe is a liquid nitrogen flow channel for passing liquid nitrogen to the magnet system. A signal line is passed through the signal pipe. The signal line is used to connect to a sensor component provided in the magnet system to transmit a signal. The housing 201 can also be used to fix the cooling pipe and the signal pipe.

[0034] It should be noted that if the superconducting cable is bent, cracks are likely to occur, resulting in reduced performance of the superconducting cable. The superconducting cable is passed through and fixed in the housing 201, and the housing 201 is provided with a mounting member for fixing the superconducting cable. The housing 201 includes a plurality of connected housing units 202. The superconducting cable is usually passed through at least two housing units 202. Therefore, the high-precision docking between the housing units 202 will reduce the positional deviation between the housing units 202, so that the superconducting cable can be installed on the mounting member of the plurality of housing units 202 without deformation and changing the bending degree, which is conducive to ensuring the performance of the superconducting cable.

[0035] The shell 201 here may be a part of the shell of the feeder 200 in the fusion reactor.

[0036] The assembly tool 100 includes a bracket assembly 30, a laser measuring device and an adjustment assembly 40. The bracket assembly 30 is used to carry the shell 201, and the bracket assembly 30 has a second group of target seats 20; the laser measuring device is used to measure the positions of the first group of target seats 10 and the second group of target seats 20, and determine the spatial position of the bracket assembly 30 and the spatial position of the shell 201 according to the positions of the first group of target seats 10 and the second group of target seats 20; the adjustment assembly 40 is provided on the bracket assembly 30, and the adjustment assembly 40 is used to adjust the position of the shell 201 relative to the bracket assembly 30 according to the measurement result of the laser measuring device so that the shell 201 is installed to the target position.

[0037] A bracket assembly 30 is used to support the shell 201 to assist in assembly. The bracket assembly 30 has a second group of target seats 20, wherein the number of the second group of target seats 20 may be one or more. By arranging the second group of target seats 20 on the bracket assembly 30, the position of the bracket assembly 30 can be determined according to the second group of target seats 20, that is, the assembly reference of the shell 201 can be determined.

[0038] The laser measurement device is used to measure the positions of the first group of target seats 10 and the second group of target seats 20, and respectively determine the spatial position of the bracket assembly 30 and the spatial position of the housing 201 according to the positions of the first group of target seats 10 and the second group of target seats 20; the adjustment assembly 40 is arranged on the bracket assembly 30, and the adjustment assembly 40 is used to adjust the position of the housing 201 relative to the bracket assembly 30 according to the measurement result of the laser measurement device so that the housing 201 is installed at the target position.

[0039] For example, compare the three-dimensional coordinates of the actual position of the first group of target seats 10 with the three-dimensional coordinates of the target position of the first group of target seats 10, and adjust the actual position of the housing 201 until the three-dimensional coordinates of the actual position of the first group of target seats 10 coincide with the three-dimensional coordinates of the target position of the first group of target seats 10, so as to install the housing 201 at the target position; alternatively, the computing device processes the measurement result of the laser measurement device to generate a real-time virtual model of the housing 201 in the computing device. A standard model of the housing 201 located at the target position is pre-stored in the computing device. Compare the position of the real-time virtual model with the position of the standard model of the housing 201, and move the actual spatial position of the housing 201 so that the positions of the real-time virtual model of the housing 201 and the standard model of the housing 201 coincide, that is, the housing 201 is installed at the target position.

[0040] According to the in-vessel feeder assembly tooling 100 of the embodiment of the present invention, by using the laser measurement device, the first group of target seats 10 and the second group of target seats 20 to assist in the assembly of the housing 201 of the in-vessel feeder 200, the housing 201 can be installed at the target position more accurately and then connected. Compared with direct manual assembly, the assembly accuracy of the housing 201 is greatly improved, and the position deviation of the connected housing 201 is reduced. Therefore, when installing the cable 203, the cable 203 can be installed at the designed position, and there will be no large deviation between the actual installation position and the designed position of the cable 203. Thus, the possibility of the cable 203 being deformed due to the installation of the cable 203 can be reduced, especially for superconducting cables, which is beneficial to ensuring that the performance of the superconducting cable will not be reduced.

[0041] According to some embodiments of the present invention, reference can be made to Figure 1 and Figure 2 , the housing 201 includes a plurality of housing units 202, and the plurality of housing units 202 are connected to form a ring. Each housing unit 202 is provided with a first group of target seats 10. The bracket assembly 30 includes a plurality of mounting positions 301. Reference can be made to Figure 3 , each mounting position 301 is provided with an adjustment assembly 40, and each housing unit 202 adjusts its position relative to the bracket assembly 30 through the adjustment assembly 40. The number of mounting positions 301 is less than the number of housing units 202.

[0042] It should be noted that multiple housing units 202 are at least partially the same. The annular housing 201 is arranged around the magnet system to meet the requirement of passing the cables 203 through multiple circumferential positions of the magnet system.

[0043] During assembly, first, multiple housing units 202 are provided; the housing units 202 are placed at the installation positions 301 of the support assembly 30; the positions of the first group of target seats 10 and the second group of target seats 20 are measured, and the spatial positions of the support assembly 30 and the housing units 202 are respectively determined according to the positions of the first group of target seats 10 and the second group of target seats 20; the position of the housing unit 202 relative to the support assembly 30 is adjusted according to the measurement results of the laser measuring device so that the housing unit 202 is installed at the target position; adjacent housing units 202 are connected. Among them, the cable 203 can be fixed on the housing unit 202 after connecting some of the housing units 202, or the cable 203 can be fixed on the housing unit 202 after connecting all the housing units 202.

[0044] Each housing unit 202 is provided with a first group of target seats 10, so that the position of each housing unit 202 can be determined according to the position of the first group of target seats 10 provided on each housing unit 202.

[0045] The support assembly 30 includes multiple installation positions 301. One installation position 301 can be used to place one housing unit 202, and each installation position 301 is provided with an adjustment assembly 40 to facilitate adjusting the position of one housing unit 202 provided at the installation position 301.

[0046] The position of each housing unit 202 relative to the support assembly 30 is adjusted through the adjustment assembly 40. The number of installation positions 301 is less than the number of housing units 202. That is to say, the annular housing 201 can be installed by using the arc-shaped support assembly 30. For example, after connecting two adjacent housing units 202, the connected part of the housing units 202 is removed from the support assembly 30, and then the unconnected housing unit 202 is placed on the support assembly 30 and connected to the part of the housing units 202 that has not been removed on the support assembly 30, so as to reduce the volume and manufacturing cost of the support assembly 30.

[0047] Exemplarily, reference can be made to Figures 1 to 3, the bracket assembly 30 may include four mounting positions 301. During installation, the four housing units 202 are respectively placed in the four mounting positions 301, and then the positions of the four housing units 202 are adjusted to the target positions. The four housing units 202 are connected, and the connected four housing units 202 are moved to one side so that two housing units 202 are removed from the bracket assembly 30. Then, another two housing units 202 are provided and placed on the bracket assembly 30. After adjusting the positions, they are connected to the original housing units 202. By repeating this cycle, the assembly of the entire housing 201 is completed.

[0048] To achieve better protection for the cable 203, after installing the cable 203 on the housing unit 202, a cover plate 205 can be installed on the housing unit 202 (reference can be made to Figure 2 ), so that the cable 203 can be threaded through the housing 201.

[0049] According to some embodiments of the present invention, reference can be made to Figure 3 , the adjustment assembly 40 includes a first adjustment member, a second adjustment member, and a height adjustment member; the first adjustment member is used to adjust the movement of the housing unit 202 along the first direction F1, the second adjustment member is used to adjust the movement of the housing unit 202 along the second direction F2, and the height adjustment member is used to adjust the movement of the housing unit 202 along the height direction. The first direction F1, the second direction F2, and the height direction F3 are perpendicular to each other in pairs.

[0050] That is to say, the adjustment assembly 40 can adjust the movement positions of the housing unit 202 in three directions to conveniently change the spatial position of the housing unit 202 according to requirements. By setting the adjustment assembly 40 to adjust the housing unit 202, the adjustment is more efficient and has better controllability, and fine adjustment can be achieved. For example, the first direction F1 can be the left - right direction in the figure, and the second direction F2 can be the front - back direction in the figure.

[0051] In other embodiments, the adjustment assembly 40 may also include only the first adjustment member and the height adjustment member, or only the second adjustment member and the height adjustment member, or only the height adjustment member.

[0052] Specifically, the first adjustment member can be provided only on one side of the housing 201 along the first direction F1, or on both sides of the housing 201 along the first direction F1; the second adjustment member can be provided only on one side of the housing 201 along the second direction F2, or on both sides of the housing 201 along the second direction F2.

[0053] According to some embodiments of the present invention, reference can be made to Figure 4, at least one of the first adjusting member, the second adjusting member, and the height adjusting member includes a threaded rod 401, the threaded rod 401 is threadedly connected to the bracket assembly 30, and one end of the threaded rod 401 abuts against the housing unit 202.

[0054] It can be understood that when it is necessary to adjust the position of the housing 201, the threaded rod 401 in the corresponding direction is rotated so that the position of the end of the threaded rod 401 abutting against the housing unit 202 is changed. Since the threaded rod 401 abuts against the housing unit 202, the position of the housing unit 202 can be changed. The position of the housing 201 is adjusted by using the threaded rod 401. In this way, the structure is simple, the use cost is low, and the support strength is good.

[0055] According to some embodiments of the present invention, one end of the first adjusting member, one end of the second adjusting member, and one end of the height adjusting member all abut against the housing unit 202 and are in rolling cooperation.

[0056] Exemplarily, one end of the threaded rod 401 abuts against the housing unit 202 and is in rolling cooperation.

[0057] In this way, when adjusting the position of the housing unit 202 in a certain direction, the friction between the adjusting assembly 40 in other directions and the housing unit 202 can be reduced, which is beneficial to making the adjustment smoother. For example, a ball 402 is provided at one end of the first adjusting member abutting against the housing unit 202, one end of the second adjusting member abutting against the housing unit 202, and one end of the height adjusting member abutting against the housing 201 (reference can be made to Figure 4 ).

[0058] In other embodiments, the first adjusting member, the second adjusting member, and the third adjusting member can also be electric telescopic rods to achieve electric control adjustment.

[0059] According to some embodiments of the present invention, reference can be made to Figure 2 , Figure 5 and Figure 8 , the housing unit 202 includes an upper flange 2011 and two side flanges 2012. The upper flange 2011 defines a top opening, and the side flanges 2012 define side openings. The top opening and the side openings are used for passing through the cable 203.

[0060] The assembly tooling 100 further includes a first fixing component 50 and a second fixing component 60. Reference can be made to Figure 6 , the first fixing component 50 connects the bracket assembly 30 and the upper flange 2011. Reference can be made to Figure 9 , and the second fixing component 60 connects the bracket assembly 30 and the side flange 2012.

[0061] On the one hand, the upper flange 2011 and the side flanges 2012 are distributed vertically. The two side flanges 2012 are distributed along a preset direction, and the preset direction forms a set angle with the vertical direction. The first fixing component 50 connects the bracket component 30 to the upper flange 2011, and the second fixing component 60 connects the bracket component 30 and the side flanges 2012. As a result, the upper and lower parts of the housing unit 202 and the two side parts of the housing unit 202 along the preset direction are all connected to the bracket component 30, which is beneficial to improving the fixing stability of the housing unit 202. On the other hand, the first fixing component 50 is connected to the upper flange 2011, and the second fixing component 60 is connected to the side flanges 2012. Therefore, there is no need to open holes or provide connection structures on the housing unit 202 to connect the first fixing component 50 and the second fixing component 60, which is beneficial to simplifying the structure of the housing unit 202.

[0062] According to some embodiments of the present invention, reference may be made to Figures 6 to 7 , the first fixing component 50 includes a first connecting rod 501 and a first threaded member 502. The first connecting rod 501 is threadedly connected to the bracket component 30. For example, a first nut is welded to the bracket component 30, and the first connecting rod 501 passes through the first nut to achieve threaded connection with the bracket component 30. The first connecting rod 501 passes through the flange hole of the upper flange 2011 and is movable along the axial direction perpendicular to the flange hole of the upper flange 2011. For example, the axial direction of the flange hole of the upper flange 2011 is the vertical direction, and the first connecting rod 501 is movable relative to the flange hole of the upper flange 2011 perpendicular to the vertical direction, so that before fixing the housing unit 202, the housing unit 202 can move relative to the first connecting rod 501. Exemplarily, the flange hole of the upper flange 2011 can be elongated. The first threaded member 502 is located on the side of the upper flange 2011 facing away from the bracket component 30 and is threadedly connected to the first connecting rod 501. When fixing the housing 201, the first threaded member 502 is tightened downward so that the housing unit 202 and the first threaded member 502 are tightened against each other to fix the position of the housing unit 202.

[0063] Exemplarily, the first threaded member 502 may include a second nut, and the outer diameter of the second nut is greater than the outer diameter of the flange hole of the upper flange 2011; or, the first threaded member 502 includes a second nut and a gasket, the gasket is disposed between the flange hole of the upper flange 2011 and the second nut, the first connecting rod 501 passes through the gasket, and the outer diameter of the gasket is greater than the outer diameter of the flange hole of the upper flange 2011.

[0064] According to some embodiments of the present invention, reference may be made to Figures 8 to 10, the bracket assembly 30 has a mounting hole 302, and the second fixing assembly 60 includes a second connecting rod 601, a connecting member 602, and a second threaded member 603. The second connecting rod 601 passes through the mounting hole 302 and is movable along the axial direction perpendicular to the mounting hole 302. In this way, after connecting the second connecting rod 601 to the side flange 2012, when adjusting the position of the housing unit 202, the second fixing assembly 60 can move relative to the bracket assembly 30 so that the position of the housing unit 202 can be adjusted normally. After adjusting the housing unit 202 to the target position, the position of the second connecting rod 601 is fixed. Exemplarily, the mounting hole 302 can be a long strip hole. The axial extension direction of the second connecting rod 601 is perpendicular to the end face orientation of the side flange 2012, so that the setting of the second fixing assembly 60 can be prevented from interfering with the connection of adjacent housing units 202 through the side flange 2012.

[0065] The connecting member 602 is connected to the second connecting rod 601. The connecting member 602 includes a convex portion 6021. The convex portion 6021 passes through the flange hole of the side flange 2012 to realize the connection between the second fixing assembly 60 and the side flange 2012. There are two second threaded members 603 and they are respectively arranged on both sides of the mounting hole 302. The second connecting rod 601 and the second threaded member 603 are threadedly connected to fix the position of the second connecting rod 601. It can be understood that by tightening the two second threaded members 603 located on both sides of the mounting hole 302, the position of the second connecting rod 601 can be fixed.

[0066] Furthermore, the connecting member 602 can include a first section 6022 and a second section 6023. The first section 6022 and the second section 6023 are connected and distributed in an L shape. The second connecting rod 601 passes through the first section 6022 and is threadedly connected to the first section 6022. The first section 6022 and the convex portion 6021 are on the same side of the second section 6023. In the state where the convex portion 6021 passes through the flange hole of the side flange 2012, by rotating the second connecting rod 601, the end face of one end of the second connecting rod 601 can be abutted against the circumferential edge of the side flange 2012, thereby realizing a more stable connection between the housing unit 202 and the second fixing assembly 60.

[0067] According to some embodiments of the present invention, reference can be made to Figure 2, the housing unit 202 includes a laterally extending section 2021 and a vertically extending section 2022. The lower end of the vertically extending section 2022 is connected to the middle of the longitudinally extending section 2021 in the length direction. The upper end of the vertically extending section 2022 is the upper flange 2011, and the two ends of the laterally extending section 2021 are respectively two side flanges 2012. Among them, the upper flange 2011 is used for threading the cable 203 in or out. Adjacent housing units 202 can be connected through the side flanges 2012. According to the cable 203 layout requirements, the side flanges 2012 are also used for threading the cable 203, that is, enabling the cable 203 to pass through from one housing unit 202 to another housing unit 202.

[0068] Reference may be made to Figure 3 , the bracket assembly 30 includes a base 303 and a plurality of connected support frames 304. The plurality of support frames 304 are connected to the top of the base 303 and arranged in a preset direction. The plurality of support frames 304 are connected, and the plurality of support frames 304 can be connected to form an integral body. In this way, the structural strength of the support frame 304 is higher. The preset direction here is consistent with the arrangement direction of the plurality of housing units 202. For example, the preset direction is arc-shaped so that the plurality of housing units 202 can form a loop after being connected to each other.

[0069] The base 303 is used to support the laterally extending section 2021. Each support frame 304 is provided with a first fixing component 50 and a second fixing component 60 to fix the corresponding housing unit 202. By arranging the first fixing component 50 and the second fixing component 60 on the support frame 304, it is convenient to remove the first fixing component 50 and the second fixing component 60 subsequently. The second set of target seats 20 are arranged on the base 303 and / or the support frames 304 to accurately obtain the position of the bracket assembly 30.

[0070] Furthermore, the height adjusting member is arranged on the base 303, and the first adjusting member and the second adjusting member can be arranged on the support frame 304.

[0071] According to some embodiments of the present invention, reference may be made to Figure 3 , each support frame 304 is provided with two stoppers 3041. The stoppers 3041 are arranged at one end of the support frame 304 away from the base 303 and on the same side of the support frame 304. An installation position 301 is defined between the two stoppers 3041. In a specific example, in the state where the housing unit 202 is placed on the bracket assembly 30, the two stoppers 3041 are arranged on both sides of the vertically extending section 2022.

[0072] During installation, each support frame 304 corresponds to a housing unit 202. Two stoppers 3041 provided on each support frame 304 define an installation position 301 for placing a housing unit 202. When installing the housing unit 202, at least part of the housing unit 202 can be first placed between the two stoppers 3041, that is, at least part of the housing unit 202 is placed in the installation position 301, so that the approximate installation position of the housing unit 202 can be conveniently determined. Subsequently, by finely adjusting the position of the housing unit 202, the housing unit 202 can be quickly adjusted to the target position. By providing two stoppers 3041 on the support frame 304 and defining the installation position 301 between the two stoppers 3041, the speed of adjusting the housing unit 202 to the target position can be increased, and the assembly efficiency of the housing 201 can be improved.

[0073] In addition, a first fixing assembly 50 can be provided on the stopper 3041 to more stably fix the position of the housing unit 202.

[0074] According to some embodiments of the present invention, reference can be made to Figure 2 and Figure 3 , at least one housing unit 202 further includes a laterally extending section 2023. The laterally extending section 2023 is connected to the bottom of the laterally extending section 2021 and at least partially extends toward the side facing away from the support frame 304; the laterally extending section 2023 can include a laterally extending flange, and the laterally extending flange defines an opening for passing through or inserting a cable 203 to meet the cable passing requirements of the cable 203.

[0075] In some embodiments, only one of the adjacent two housing units 202 may be provided with a laterally extending section 2023 to reduce the overall structural complexity and volume of the housing 201.

[0076] The base 303 has an avoidance space 3031 for avoiding the laterally extending section 2023. By providing the avoidance space 3031 on the base 303 to avoid the laterally extending section 2023, the assembly of the laterally extending section 2023 and the cable layout are facilitated.

[0077] According to some embodiments of the present invention, reference can be made to Figure 5 , the support assembly 30 further includes a strengthening connection frame 305. The strengthening connection frame 305 is located on the side of the support frame 304 facing away from the housing unit 202, and the base 303 and the support frame 304 are connected by the strengthening connection frame 305.

[0078] By providing the reinforcing connecting frame 305, when the support frame 304 is subjected to force, the support frame 304 can transfer the external force to the base 303, so that the support frame 304 and the base 303 bear the force together. Therefore, it is beneficial to improve the support strength of the support frame 304, making the support frame 304 not prone to shaking, and further beneficial to making the position stability of the housing 201 better.

[0079] More specifically, the reinforcing connecting frame 305 can be a reinforcing rod or a frame formed by a plurality of connected reinforcing rods.

[0080] According to some embodiments of the present invention, reference may be made to Figure 2 and Figure 11 , the in-vessel feeder 200 of the fusion reactor further includes a connector 204 for connecting with the cable 203, and the assembly tooling 100 further includes a fixing frame 70 installed on the upper flange 2011 for fixing the positions of the connector 204 and the cable 203.

[0081] It should be noted that the cable 203 needs to be connected to the connector 204, and the fixing frame 70 is provided to fix the positions of the connector 204 and the cable 203, so as to facilitate the subsequent connection of the connector 204 and the cable 203. For example, the connector 204 and the cable 203 are welded and connected. After the connection of the connector 204 and the cable 203 is completed, the fixing frame 70 needs to be removed.

[0082] It can be understood that even after the housing unit 202 is installed at the target position, the actual position of the housing unit 202 will inevitably have an allowable deviation from the target position, that is, the relative position between the housing unit 202 and the support assembly 30 cannot reach the preset relative position without deviation. Therefore, if the fixing frame 70 is installed on the support assembly 30, it may cause a large deviation between the relative position of the fixing frame 70 and the cable 203 and the preset relative position. In this embodiment, the fixing frame 70 is provided on the housing unit 202, so that the deviation accumulation can be reduced, the relative position deviation between the fixing frame 70 and the cable 203 can be reduced, the fixing positions of the cable 203 and the connector 204 can be made more accurate, and the possibility of deformation of the cable 203 can be reduced.

[0083] More specifically, reference may be made to Figure 11As shown, the fixing bracket 70 includes a vertical support plate 701. The lower end of the vertical support plate 701 is connected to the upper flange 2011. A clamping member 702 is provided on one side of the vertical support plate 701. The clamping member 702 is used to clamp the joint 204 and the cable 203. According to the situation, two clamping members 702 can be provided to clamp the joint 204, and one clamping member 702 can be provided at a position where the cable 203 is close to the joint 204 to clamp the cable 203. More specifically, the clamping member 702 can include a first clamping portion and a second clamping portion. The first clamping portion is provided on the vertical support plate 701, and the second clamping portion is provided on a side of the first clamping portion facing away from the vertical support plate 701. The position between the first clamping portion and the second clamping portion is adjustable to clamp the joint 204 and the cable 203 and can detach the joint 204 and the cable 203 from the fixing bracket 70.

[0084] According to some embodiments of the present invention, reference can be made to Figure 12 , the in-vessel feeder assembly tooling 100 of the fusion reactor further includes a plurality of support components 80 and a plurality of moving wheels 90. The plurality of support components 80 and the plurality of moving wheels 90 are both provided at the bottom of the bracket assembly 30. The position of the lower end of the support component 80 relative to the bracket assembly 30 is adjustable. In a state where the lower end of the support component 80 is lower than the lower end of the moving wheel 90, the support component 80 supports the bracket assembly 30. In a state where the lower end of the moving wheel 90 is lower than the lower end of the support component 80, the moving wheel 90 supports the bracket assembly 30.

[0085] For example, when assembling the housing 201 using the bracket assembly 30, the support component 80 can be made to support the bracket assembly 30 so that the position of the bracket assembly 30 does not change; at the same time, the height of the bracket assembly 30 can be adjusted within a certain height range. In this way, the use of the bracket assembly 30 is more flexible; adjusting the plurality of support components 80 can level the bracket assembly 30 so that the bracket assembly 30 can adapt to different ground environments.

[0086] When it is necessary to remove the housing unit 202 from the bracket assembly 30, an external support can be used to support the plurality of connected housing units 202, and then the support component 80 is adjusted to separate the bracket assembly 30 from the housing unit 202. Then, the position of the bracket assembly 30 is moved through the moving wheels 90 so that the bracket assembly 30 can be moved to a corresponding position of the housing unit 202 to be connected.

[0087] Exemplarily, the support component 80 includes a threaded support column and a threaded sleeve. The upper end of the threaded support column is connected to the bracket assembly 30, and the lower end of the threaded support column is connected with a threaded sleeve. When it is necessary to adjust the height of the bracket assembly 30, the threaded sleeve can be rotated.

[0088] The second aspect of the present invention also proposes a method for assembling an in-vessel feeder of a fusion reactor.

[0089] The assembly method of the internal feeder according to an embodiment of the present invention is based on the fusion reactor internal feeder assembly tooling 100 of any of the above embodiments, and includes: S1: Provide a plurality of housing units 202; S2: Place the housing unit 202 at the installation position 301 of the support assembly 30; S3: Measure the positions of the first group of target seats 10 and the second group of target seats 20, and respectively determine the spatial position of the support assembly 30 and the spatial position of the housing 201 according to the positions of the first group of target seats 10 and the second group of target seats 20; S4: Adjust the position of the housing unit 202 relative to the support assembly 30 according to the measurement result of the laser measurement device so that the housing unit 202 is installed at the target position; S5: Connect adjacent housing units 202.

[0090] Wherein, measuring the position of the first group of target seats 10 is to determine the position of the support assembly 30. Since the housing unit 202 needs to be adjusted on the support assembly 30 and fixed on the support assembly 30, therefore, it is necessary to obtain the position of the support assembly 30 to know the relative position between the housing unit 202 and the support assembly 30.

[0091] According to the assembly method of the fusion reactor internal feeder of the embodiment of the present invention, a laser measurement device, the first group of target seats 10 and the second group of target seats 20 are used to assist in the assembly of the housing 201 of the fusion reactor internal feeder 200, and the housing 201 can be installed at the target position more accurately and then connected. Compared with direct manual assembly, the assembly accuracy of the housing 201 is greatly improved, and the position deviation of the connected housing 201 is reduced. Therefore, when installing the cable 203, the cable 203 can be installed at the designed position, and there will be no large deviation between the actual installation position and the designed position of the cable 203. Thus, the possibility of the cable 203 being deformed due to the installation of the cable 203 can be reduced, especially for superconducting cables, which is beneficial to ensuring that the performance of the superconducting cable will not be reduced.

[0092] In some embodiments, after installing the housing unit 202 at the target position, it further includes: threading and fixing the cable 203 through the housing unit 202.

[0093] Exemplarily, before connecting adjacent housing units 202, after installing the housing unit 202 at the target position, the cable 203 can be threaded and fixed to the housing 201. Exemplarily, after connecting adjacent housing units 202, the cable 203 can also be threaded and fixed to the housing 201.

[0094] It should be noted that the overall threading shape of the cable 203 is fixed before the cable 203 is to be fixed to the housing 201. Therefore, when threading the cable 203, the cable 203 is directly placed in the housing unit 202, and then the cover plate 205 is covered on the open end of the housing unit 202 so that the cable 203 can be threaded through the housing 201.

[0095] Thread and fix the cable 203 to the housing 201. In this way, the possibility of significant deformation of the cable 203 during use can be reduced, which is beneficial to ensuring the performance of the cable 203. The housing 201 can also protect the cable 203 so that the cable 203 is not easily damaged accidentally.
