During the processing and manufacturing process, due to the thin thickness, large area and curved surface of the cold shield device, the precision of the cold shield device after processing and forming is difficult to control. In addition, certain welding is required on the surface of the cold shield panel, such as welding the cold shield panel to the flange, and welding the cold shield panel to the pipeline. The welding process will also cause certain deformation of the thin-walled and large-curved cold shield panel. At the same time, gravity will also have a certain impact on the contour deformation of the cold shield device. The installation of the cold shield device also has contour requirements for the cold shield device, so the cold shield device needs to be corrected and contour measured.

[0035] Reference below Figure 1 and Figure 2 A nuclear fusion cold shield correction and measurement composite assembly 100 according to an embodiment of the present invention is described.

[0036] like Figure 1 As shown, the correction and measurement composite assembly 100 of the nuclear fusion cold shield device according to an embodiment of the present invention includes a correction tool 1 and a laser contour measurement device 2.

[0037] Specifically, the nuclear fusion cold shield device correction and measurement composite assembly 100 is used for the cold shield device 200, and the correction tool 1 is used to correct the cold shield device 200 to adjust the contour of the cold shield device 200. The laser contour measurement device 2 is connected to the correction tool 1 and is used to measure the contour of the cold shield device 200.

[0038] Cold shields 200 are commonly used in nuclear fusion tokamaks. They isolate the heat between the high-temperature plasma and the superconducting magnets, ensuring the magnets operate at extremely low temperatures. These shields are typically made of silver-plated stainless steel panels and are large, thin, lightweight, and easily deformable.

[0039] The correction tool 1 can correct the cold shield device 200, that is, adjust the shape of the cold shield device 200, thereby adjusting the contour of the cold shield device 200. For example, the correction tool 1 can be provided with a hydraulic device 14 for providing a controllable force to the cold shield device 200, so that the cold shield device 200 changes shape under the pressure applied by the correction tool to meet the contour requirements.

[0040] The orthopedic tool 1 includes a first orthopedic portion 11 and a second orthopedic portion 12, with at least a portion of the cold shield device 200 disposed between the first orthopedic portion 11 and the second orthopedic portion 12. During the orthopedic process, the orthopedic tool 1 can be moved relative to the cold shield device 200 so that the area of ​​the cold shield device 200 requiring orthopedic treatment is located between the first orthopedic portion 11 and the second orthopedic portion 12, thereby facilitating the orthopedic tool 1 to apply pressure to the cold shield device 200, thereby achieving the desired orthopedic effect.

[0041] The laser contour measurement device 2 can perform contour measurement on the cold shield device 200, such as measuring the cold shield device 200 using principles such as laser triangulation measurement, thereby obtaining the contour of the cold shield device 200, and determining the area on the cold shield device 200 that does not meet the contour requirements, so that the cold shield device 200 can be corrected in a targeted manner.

[0042] The laser contour measurement device 2 is connected to the correction tool 1, thereby enabling real-time contour measurement of the cold shield device 200 while the correction is being performed. This facilitates adjustment of the correction force applied to the cold shield device 200, thereby improving correction accuracy and efficiency. Furthermore, during the correction process of the cold shield device 200, it is possible to detect in real time whether the correction process has adverse effects on areas around the correction location that originally met the contour requirements, and to adjust and correct the area in real time based on the actual situation, thereby ensuring that the corrected area and the area surrounding the correction location meet the contour requirements.

[0043] In the prior art, contour measurement is generally followed by correction, and overall correction is followed by contour measurement, and this process is repeated alternately. The nuclear fusion cold shield correction and measurement composite assembly 100 of the present application allows for real-time contour detection of the cold shield 200 while correcting the cold shield 200. This improves correction efficiency and avoids overcorrection, thereby preventing metal fatigue caused by repeated deformation of the cold shield 200.

[0044] Among them, such as Figure 1 As shown, the laser profilometry device 2 includes a transmitter 21 and a receiver 22. The transmitter 21 is fixedly connected to the orthopedic tool 1 and is used to transmit laser light toward the cold shield 200. The receiver 22 and the transmitter 21 are located on the same side of the cold shield 200 in the thickness direction. The receiver 22 is used to receive the laser light reflected by the cold shield 200.

[0045] The transmitter 21 emits a laser line or surface toward the cold shield 200. The receiver 22 is positioned at a specific angle to the transmitter 21. The laser strikes the surface of the cold shield 200 and reflects. The receiver 22 then receives the reflected laser light. By using the pre-calibrated geometric relationship between the transmitter 21 and receiver 22, and combining the laser light emitted by the transmitter 21 with the laser light received by the receiver 22, an algorithm can be used to determine the three-dimensional coordinates of each point on the surface of the cold shield 200, thereby enabling contour measurement of the cold shield 200.

[0046] According to the nuclear fusion cold shield device correction and measurement composite assembly 100 of the embodiment of the present invention, the laser measuring contour device 2 is connected to the correction tool 1, wherein the correction tool 1 is used to correct the cold shield device 200 to adjust the contour of the cold shield device 200, and the laser measuring contour device 2 is used to measure the contour of the cold shield device 200. While correcting the cold shield device 200, the contour of the cold shield device 200 can be detected in real time, which is conducive to adjusting the correction force of the cold shield device 200, and can also ensure that the corrected area and the area around the correction position meet the contour requirements, thereby improving the correction efficiency and improving the correction accuracy.

[0047] In some embodiments of the present invention, the orthopedic tooling 1 can be moved relative to the cold shield device 200. Specifically, the orthopedic tooling 1 can be moved in any direction relative to the cold shield device 200. In this way, the orthopedic tooling 1 can perform corrections on different areas of the cold shield device 200, thereby improving the adaptability and flexibility of the orthopedic tooling 1.

[0048] In some embodiments of the present invention, Figure 1 As shown, the orthopedic tool 1 further includes a connecting portion 13, which is spaced apart from the cold shield device 200. The connecting portion 13 is connected at both ends in the longitudinal direction to the first orthopedic portion 11 and the second orthopedic portion 12. As a result, the first orthopedic portion 11 and the second orthopedic portion 12 can be formed as a whole, thereby enabling synchronous movement relative to the cold shield device 200 to ensure the orthopedic function.

[0049] Among them, the connecting part 13 and the cold shield device 200 are spaced apart, that is, a moving space is separated between the connecting part 13 and the cold shield device 200 to allow the corrective tool 1 to move relative to the cold shield device 200, thereby ensuring that the corrective tool 1 can correct different areas of the cold shield device 200.

[0050] In some embodiments of the present invention, the orthopedic tool 1 further includes a hydraulic device 14, which is located on a side of at least one of the first orthopedic portion 11 and the second orthopedic portion 12 proximal to the cold shield 200. The hydraulic device 14 is configured to apply pressure to the cold shield 200 to correct the shape of the cold shield 200. The hydraulic device 14 is controlled to apply a certain pressure to the cold shield 200, causing it to deform and achieve the desired correction. The hydraulic device 14 can also be used to adjust the pressure applied to the cold shield 200, thereby adjusting the correction force and avoiding overcorrection.

[0051] Among them, the hydraulic device 14 can be arranged only on one side of the first corrective part 11 close to the cold shield device 200. During correction, the hydraulic device 14 can adjust the distance between it and the second corrective part 12, so that the cold shield device 200 is clamped between the hydraulic device 14 and the second corrective part 12. At the same time, the hydraulic device 14 can adjust the pressure applied to the cold shield device 200, thereby achieving the correction purpose and making the cold shield device 200 meet the contour requirements.

[0052] Similarly, the hydraulic device 14 can also be arranged only on the side of the second corrective part 12 close to the cold shield device 200. During correction, the hydraulic device 14 can adjust the distance between it and the first corrective part 11, so that the cold shield device 200 is clamped between the hydraulic device 14 and the first corrective part 11. At the same time, the hydraulic device 14 can adjust the pressure applied to the cold shield device 200.

[0053] In addition, the hydraulic device 14 can also be simultaneously provided on one side of the first orthopedic part 11 and the second orthopedic part 12 close to the cold shield device 200. During correction, the distance between the hydraulic device 14 on the first orthopedic part 11 and the hydraulic device 14 on the second orthopedic part 12 can be adjusted so that the cold shield device 200 is clamped between the hydraulic device 14 on the first orthopedic part 11 and the hydraulic device 14 on the second orthopedic part 12. At the same time, the hydraulic device 14 can adjust the pressure applied to the cold shield device 200.

[0054] In some embodiments of the present invention, Figure 1 As shown, the laser profiling device 2 further includes a fixing frame 23, which includes a fixing portion 231 and an extending portion 232. The fixing portion 231 is connected to the orthopedic tool 1, and the extending portion 232 extends in the radial direction of the fixing portion 231. The two ends of the extending portion 232 are respectively connected to the fixing portion 231 and the emitter 21. The fixing portion 231 facilitates the fixation of the emitter 21 to the orthopedic tool 1. By providing the extending portion 232, the emitter 21 can be separated from the fixing portion 231 and the orthopedic tool 1 while maintaining the connection between the emitter 21 and the fixing portion 231. This effectively prevents the fixing portion 231 and the orthopedic tool 1 from blocking the laser light emitted by the emitter 21, thereby ensuring the measurement function and measurement stability of the laser profiling device 2.

[0055] In some embodiments of the present invention, Figure 1 As shown, there are multiple emitters 21 corresponding one to one with the extension portion 232, and the multiple emitters 21 are spaced apart along the circumferential direction of the fixing portion 231. The multiple emitters 21 can simultaneously emit laser light toward the cold shield device 200, thereby enabling multi-point measurement and expanding the detection area of ​​the cold shield device 200 by the laser profilometer 2, thereby improving detection efficiency and accuracy.

[0056] Specifically, if Figure 1 In the example shown, there are three emitters 21, which are equidistantly spaced along the circumferential direction of the fixing portion 231. In addition, the number of emitters 21 connected to the fixing portion 231 can also be 2, 4, 5, 6, etc., which is not specifically limited in this application.

[0057] In some embodiments of the present invention, the nuclear fusion cold shield device correction and measurement composite assembly 100 further includes a contouring tooling having a fixing groove for clamping and securing at least a portion of the corrected cold shield device 200. At least a portion of the corrected cold shield device 200 can be inserted into the fixing groove for clamping and securing, thereby ensuring the structural stability of the corrected cold shield device 200 and preventing further deformation and repeated correction, thereby reducing the risk of metal fatigue in the cold shield device 200.

[0058] The following combination Figure 2 A combined correction and measurement method for a nuclear fusion cold shield device according to an embodiment of the present invention is described. The combined correction and measurement method for a nuclear fusion cold shield device is implemented by the above-mentioned combined correction and measurement assembly 100 for the nuclear fusion cold shield device.

[0059] A combined correction and measurement method for a nuclear fusion cold shield device according to an embodiment of the present invention includes:

[0060] Measuring the profile of the cold shield device 200;

[0061] Determining a first area on the cold shield device 200 that does not meet the contour requirement;

[0062] Correction is performed on the first area, and contour measurement is performed on the correction position and a second area with the correction position as the center.

[0063] Specifically, the cold shield device 200 is first profiled using the laser profile measurement device 2, such as by using a laser triangulation method, to measure the cold shield device 200, thereby obtaining the profile of the cold shield device 200. The measured profile is then compared with the profile requirement, and the area on the cold shield device 200 that does not meet the profile requirement is the first area.

[0064] Then, the first region that does not meet the contour requirement is corrected by the correction tool 1 , that is, the shape of the cold shield device 200 in the first region is adjusted, thereby adjusting the contour of the cold shield device 200 in the first region.

[0065] During correction, the laser contour measurement device 2 is used to measure the contour of the correction position of the cold screen device 200 and the second area with the correction position as the center. In this way, it is possible to detect in real time whether the correction process has an adverse effect on the area around the correction position that originally meets the contour requirements, and it is convenient to adjust the correction area or correct it again in real time according to actual conditions, so as to ensure that the corrected area and the area around the correction position meet the contour requirements.

[0066] While the cold shield device 200 is being corrected, the contour of the cold shield device 200 is detected in real time, which is beneficial to adjusting the correction force of the cold shield device 200, thereby improving the correction accuracy and efficiency.

[0067] According to the composite method for correction and measurement of a nuclear fusion cold shield device of an embodiment of the present invention, by performing contour measurement on the correction position and the second area with the correction position as the center while correcting the first area that does not meet the contour requirements, it is possible to perform real-time contour detection on the cold shield device 200 while correcting the cold shield device 200, which is beneficial for adjusting the correction force of the cold shield device 200, and can also ensure that the corrected area and the area around the correction position meet the contour requirements, thereby improving the correction efficiency and improving the correction accuracy.

[0068] In some embodiments of the present invention, the profile requirement includes a profile accuracy within ±5 mm. Thus, by combining the correction and measurement method for the nuclear fusion cold shield device, areas of the cold shield device 200 with a profile accuracy outside of ±5 mm can be corrected, thereby ensuring that the profile of the cold shield device 200 is within ±5 mm, thereby meeting the installation requirements of the cold shield device 200.

[0069] In some embodiments of the present invention, Figure 1 and Figure 2 As shown, the cold shield device 200 includes a cold shield panel 3 and a flange 4, the cold shield panel 3 and the flange 4 are connected, and the flange 4 is provided at the outer edge of the cold shield panel 3. Measuring the contour of the cold shield device 200 includes:

[0070] The contour of the flange 4 is measured first, and after the flange 4 is shaped, the contour of the cold shield panel 3 is measured.

[0071] It is understandable that the laser contour measuring device 2 is first used to measure the contour of the flange 4 of the cold shield device 200 to determine the first area on the flange 4 that does not meet the contour requirements, and then the first area on the flange 4 that needs to be corrected is corrected using the correction tool 1. While correcting the flange 4, the laser contour measuring device 2 is also used to measure the contour of the correction position on the flange 4 and the second area on the flange 4 with the correction position as the center of the circle. In this way, it is possible to detect in real time whether the correction process has an adverse effect on the area around the correction position on the flange 4 that originally met the contour requirements, and to facilitate real-time adjustment of the correction area or re-correction according to actual conditions, thereby ensuring that the corrected area of ​​the flange 4 and the area around the correction position meet the contour requirements.

[0072] After the flange 4 is completely corrected, the contour of the cold shield panel 3 of the cold shield device 200 is measured using the laser contour measurement device 2 to determine the first area on the cold shield panel 3 that does not meet the contour requirements. The first area on the cold shield panel 3 that needs correction is then corrected using the correction tool 1. While correcting the cold shield panel 3, the contour of the correction position on the cold shield panel 3 and the second area on the cold shield panel 3 with the correction position as the center of the circle are also measured using the laser contour measurement device 2. This allows real-time detection of whether the correction process has adverse effects on areas around the correction position on the cold shield panel 3 that originally met the contour requirements, and facilitates real-time adjustment or re-correction of the correction area based on actual conditions, thereby ensuring that the corrected areas of the cold shield panel 3 and the areas around the correction position meet the contour requirements.

[0073] The flange 4 on the cold shield device 200 is generally thicker than the cold shield panel 3 and much narrower than the cold shield panel 3. Therefore, the flange 4 itself has greater structural strength than the cold shield panel 3. Therefore, the flange 4 is measured and shaped first, followed by the cold shield panel 3. This prevents the shaped flange 4 from causing further deformation and other adverse effects on the already shaped cold shield panel 3 during shaped flange 4 shaping. Furthermore, the probability of shaped flange 4 being adversely affected during shaped cold shield panel 3 shaping is significantly reduced, thereby further optimizing shaped flange 4 efficiency.

[0074] In some embodiments of the present invention, Figure 2 As shown, after the flange 4 is corrected and before the contour of the cold shield panel 3 is measured, measuring the contour of the cold shield device 200 further includes:

[0075] The flange 4 is clamped and fixed, which can further improve the structural stability of the flange 4 after correction, avoid deformation and repeated correction, and help reduce the risk of metal fatigue of the flange 4.

[0076] In some embodiments of the present invention, after the cold shield panel 3 is corrected, measuring the contour of the cold shield device 200 further includes:

[0077] Measure the overall contour of the cold shield device 200 again. After the flange 4 and the cold shield panel 3 are completely corrected, measure the overall contour of the cold shield device 200 again. If it is found that there are still areas that do not meet the contour requirements, repeat the above correction and measurement methods, correct the areas that do not meet the requirements while maintaining real-time contour measurement until there are no areas that do not meet the contour requirements in the cold shield device 200. This ensures that the cold shield device 200 as a whole meets the contour requirements, improves the accuracy of the correction of the cold shield device 200 by the combined correction and measurement method of the nuclear fusion cold shield device, and thus improves the quality of the cold shield device 200.

[0078] In some embodiments of the present invention, the diameter of the second area is greater than or equal to 200 mm. That is, while the correction is being performed, the laser profiling device 2 performs a profile measurement on an area of ​​the cold shield device 200 with a diameter of at least 200 mm and centered at the correction location. This allows for real-time detection of whether the correction process has adverse effects on an area with a diameter of at least 200 mm surrounding the correction location.

[0079] If the diameter of the second area is less than 200mm, the detection range is too small, which will reduce the accuracy of contour detection. Of course, the diameter of the second area cannot be too large. It needs to be within the detection range achievable by existing technology and ensure that the detection cost is controlled. The diameter of the second area can specifically be 200mm, 210mm, 220mm, 230mm, 240mm, 250mm, 260mm, 270mm, 280mm, 290mm, 300mm, 310mm, 320mm, 330mm, 340mm, 350mm, 360mm, 370mm, 380mm, 390mm, 400mm, etc. This application does not specifically limit the specific diameter of the second area.

[0080] In some embodiments of the present invention, Figure 2 As shown, after the profile measurement of the second area,

[0081] determining whether the second region meets the contour requirements;

[0082] If the second area does not meet the contour requirements, correcting the second area until the second area meets the contour requirements;

[0083] If the second area meets the contour requirements, the first area is continuously corrected until the first area meets the contour requirements.

[0084] It can be understood that while the correction is being performed on the first area, the contour measurement is performed on the correction position and the second area with the correction position as the center.

[0085] If the laser contour measurement device 2 detects that the second area does not meet the contour requirements, it is necessary to use the correction tool 1 to correct the area of ​​the cold shield device 200 that does not meet the contour requirements again. While correcting again, continue to maintain the contour measurement of the cold shield device 200 and correct the area of ​​the cold shield device 200 that does not meet the contour requirements again until it is detected that the second area of ​​the cold shield device 200 meets the contour requirements.

[0086] If the laser contour measurement device 2 detects that the second area meets the contour requirement while the first area is being corrected, the correction is continued on other positions of the first area of ​​the cold shield device 200 until the first area meets the contour requirement.

[0087] In some embodiments, while correcting the first area, contour measurements are performed on the corrective position and a second area with the corrective position as the center. If the laser contour measurement device 2 detects that the second area does not meet the contour requirements, data analysis can be performed based on the specific parameter deviation value of the second area that does not meet the contour requirements, so as to determine whether the corrective pressure applied by the corrective tool 1 to the cold shield device 200 is appropriate, and after data collection and analysis, the corrective pressure applied by the corrective tool 1 to the cold shield device 200 is corrected, thereby helping to reduce the adverse effects of the corrective process on the area around the corrective position that originally met the contour requirements.

[0088] It should be noted that the cold shield device 200 also includes a cold shield pipe, which is provided on at least one surface of both sides of the cold shield panel 3 in the thickness direction. A low-temperature medium circulates in the cold shield pipe, which can remove the heat radiation absorbed by the cold shield panel 3 through forced convection, thereby playing a cooling role. When the correction tool 1 corrects the cold shield panel 3, the correction tool 1 needs to avoid the cold shield pipe and only correct the cold shield panel 3. When the laser contour measurement device 2 detects that the position on the cold shield panel 3 relative to the cold shield pipe does not meet the contour requirements, the correction tool 1 corrects the position of the area that does not meet the contour requirements and is not blocked by the cold shield pipe to avoid damage to the cold shield pipe.
