Description

Technical Field

[0001] The present invention relates to the technical field of fusion devices, and in particular to an acceptance detection method and device for a cold shield device. Background Art

[0002] The cold shield is one of the key systems of a controllable nuclear fusion device. Among them, the vacuum chamber cold shield is located in a narrow space between the vacuum chamber and the TF magnet. Its main function is to reduce the thermal load exerted by high-temperature components on the low-temperature superconducting magnet during the normal operation of the main machine, ensuring that the superconducting magnet can work properly. In order to achieve a good thermal shielding effect, it is required that the main body of the cold shield does not contact the vacuum chamber and the magnet. Otherwise, a large amount of increased conduction heat will cause the cold shield to fail. Because in a compact nuclear fusion device, the gap between the vacuum chamber and the magnet is very small, the contour tolerance of the cold shield body is required to be very strict. In addition, due to the complex structure of the fusion device and a very long installation period of two to three years, and the cold shield components are delivered in batches, therefore, how to solve the qualified acceptance before the cold shield assembly has become one of the urgent problems to be solved currently.

[0025] Next, reference will be made to Figures 1 - 12 and in combination with the embodiments, the present invention will be described in detail.

[0026] Reference Figure 1 and Figure 2, in the acceptance test method of the cold shield device according to the embodiments of the present invention, the cold shield device is applied to a nuclear fusion device. The cold shield device includes a plurality of cold shield segments 10 assembled into a ring along the circumferential direction. The cold shield segment 10 includes an outer panel 11, an inner panel 12, and a connecting component 13. There are a plurality of outer panels 11 which are sequentially connected through the connecting component 13. There are a plurality of inner panels 12 which are sequentially connected through the connecting component 13. Each inner panel 12 is connected to at least one outer panel 11 through the connecting component 13. The plurality of outer panels 11 and the plurality of inner panels 12 are jointly assembled into a ring. The outer panel 11 is provided with a half window 111a, and the half windows 111a between some adjacent two of the plurality of outer panels 11 are arranged adjacent to each other.

[0027] The cold shield segment 10 may refer to at least a part of the composition structure of the cold shield device, and is jointly composed of the outer panel 11, the inner panel 12, and the connecting component 13. Among them, the cold shield segment 10 is integrally annular, and the annulus may be, but is not limited to, a D shape, an O shape, etc. The shapes of the outer panel 11 and the inner panel 12 may be, but are not limited to, arc-shaped panels or multi-curvature panels, etc. The connecting component 13 refers to a structure that connects two adjacent outer panels 11, two adjacent inner panels 12, and adjacent outer panels 11 and inner panels 12. The connecting component 13 can be understood to at least include a flange, and the thickness of the flange is greater than that of the outer panel 11 and the inner panel 12, having higher strength and stiffness, which can improve the connection reliability of two adjacent outer panels 11, two adjacent inner panels 12, and adjacent outer panels 11 and inner panels 12.

[0028] Based on the structural characteristics of the cold shield device, the outer panel 11 is provided with a half window 111a, and the half window 111a may be a notch opened on one side of the outer panel 11 (see Figure 1 ). "The half windows 111a between some adjacent two of the plurality of outer panels 11 are arranged adjacent to each other" can be understood as: among the plurality of outer panels 11, the half windows 111a of some adjacent two outer panels 11 are arranged adjacent to each other, so that the two half windows 111a can form a complete window structure. There are also cases where the half windows 111a of two adjacent outer panels 11 may be arranged back to back, that is, the openings of the two half windows 111a face in opposite directions. Referring to Figure 1 , each cold shield segment 10 may include four outer panels 11 and two inner panels 12. Among the four outer panels 11, the half windows 111a of the two outer panels 11 located in the middle position are arranged adjacent to each other, that is, the two half windows 111a face each other, and the half windows 111a of the outer panels 11 located on both sides are arranged back to back with the half windows 111a in the middle position.

[0029] Based on the cold shield device with the above structure, as shown in Figure 2 and Figure 3 , the acceptance test method of the cold shield device includes: Install multiple window fixing plates 220 on the test bracket 210.

[0030] Fit and install the half-window 111a of the outer panel 11 on the window fixing plate 220, and assemble it with the inner panel 12 and the connection component 13 to form the cold shield segment 10.

[0031] Scan the cold shield segment 10 to obtain measurement data, compare the measurement data with the theoretical data of the theoretical model of the cold shield segment 10 to obtain a comparison result, and determine whether the cold shield segment 10 is qualified according to the comparison result.

[0032] In the above acceptance testing method, the window fixing plate 220 can refer to a plate structure that can fix the window structure, and the outer contour of the window fixing plate 220 is consistent with the inner contour of the window structure. Among them, according to the number of half-windows 111a of the cold shield segment 10, there can be multiple window fixing plates 220. The shapes and sizes of the multiple window fixing plates 220 can be the same or different, and the window fixing plate 220 corresponding to the size of the half-window 111a can be selected.

[0033] By first installing multiple window fixing plates 220 on the test bracket 210, and then assembling the outer panel 11, the inner panel 12 and the connection component 13 on the window fixing plate 220 to form a pre-assembled cold shield segment 10, the sampling test of the pre-assembled cold shield segment 10 can be used for acceptance evaluation. The window fixing plate 220 on the test bracket 210 can simulate the real installation scenario of the cold shield device in the nuclear fusion device, provide the support and stress state for assembling multiple cold shield segments 10 into a ring, and provide a stable and accurate benchmark for the assembly of the cold shield segment 10, so as to ensure the accurate relative position between components, improve the assembly accuracy of the cold shield segment 10, and further improve the accuracy of acceptance testing.

[0034] Refer to Figure 2 , the cold shield segment 10 includes four outer panels 11 and two inner panels 12. The four outer panels 11 are respectively the first outer panel 101, the second outer panel 102, the third outer panel 103 and the fourth outer panel 104, and the two inner panels 12 are respectively the first inner panel 121 and the second inner panel 122. Therefore, three window fixing plates 220 need to be set, and the three window fixing plates 220 are respectively the first window fixing plate 221, the second window fixing plate 222 and the third window fixing plate 223.

[0035] During the pre-assembly process of the cold shield fan segment 10, the first window fixing plate 221 is installed on the test bracket 210 and is centered. The second window fixing plate 222 and the third window fixing plate 223 are arranged on both sides of the first window fixing plate 221. Then, the first outer panel 101 and the second outer panel 102 are installed on the first window fixing plate 221 and are connected by the connecting component 13. Then, the third outer panel 103 is installed on the second window fixing plate 222 and is connected to the first outer panel 101 by the connecting component 13. Next, the fourth outer panel 104 is installed on the third window fixing plate 223 and is connected to the second outer panel 102 by the connecting component 13. Then, the first inner panel 121 is connected to the fourth outer panel 104 and the second outer panel 102 by the connecting component 13. Finally, the second inner panel 122 is connected to the first outer panel 101 and the third outer panel 103 by the connecting component 13.

[0036] The cold shield fan segment 10 may further include a top panel 14, and the top panel 14 is installed at an appropriate position as needed. For example, the top panel 14 can be connected to the open positions of the first outer panel 101 and the second outer panel 102 through the connecting component 13.

[0037] After the pre-assembly of the cold shield fan segment 10 is completed, the assembled cold shield fan segment 10 can be scanned to obtain measurement data, and the measurement data is compared with the theoretical parameters of the theoretical model of the cold shield fan segment 10 to obtain a comparison result, so as to detect whether the processing of the cold shield fan segment 10 is within the allowable error range. Determining whether the processing of the cold shield fan segment 10 is qualified according to the comparison result helps to timely discover and correct problems, ensure that the final product meets the design requirements, and improve the product quality of multiple cold shield fan segments 10 after being actually assembled into a cold shield device.

[0038] According to the acceptance detection method of the cold shield device according to the embodiment of the present invention, installing on the test bracket 210 through the window fixing plate 220 can simulate the support and force states during actual assembly for the assembly of the cold shield fan segment 10. Then, the cold shield fan segment 10 is pre-assembled on the window fixing plate 220, and then the cold shield fan segment 10 is scanned and measured to obtain measurement data. The measurement data is compared with the theoretical data of the theoretical model of the cold shield fan segment 10 to obtain a comparison result, and whether the cold shield fan segment 10 is qualified is determined according to the comparison result. The quality control of the cold shield fan segment 10 during the manufacturing and acceptance handover process can be realized, so that problems can be discovered in time during the production process, and unqualified products can be prevented from entering the subsequent installation and use stages. Furthermore, additional costs such as rework and repair caused by product quality problems can be reduced, the production process can be optimized, the production efficiency can be improved, and at the same time, the production cost of the cold shield device can also be reduced.

[0039] In some embodiments of the present invention, the step of "scanning the cold shield fan segment to obtain measurement data" described above may include: The inner contour surface of the cold shield segment 10 is scanned to obtain first measurement data.

[0040] The outer contour surface of the connecting assembly 13 outside the cold shield segment 10 is scanned to obtain second measurement data.

[0041] In the above technical solution, the first measurement data may refer to graphical data obtained by scanning and reconstructing the internal contour surface of the cold shield segment 10, for example, a graphical representation of the internal contour surface of the cold shield segment 10 displayed in 3D software. The second measurement data may refer to graphical data obtained by scanning and reconstructing the external contour surface of the connecting component 13, for example, a graphical representation of the external contour surface of the connecting component 13 displayed in 3D software.

[0042] Since the thickness of the outer panel 11 and the inner panel 12 is generally thin, the overall wall thickness of the cold shield segment 10 is also thin. Therefore, it is only necessary to obtain the first measurement data by scanning the internal contour surface of the cold shield segment 10. Then, based on the first measurement data, it is possible to analyze whether the internal contour surface is deformed or whether the overall contour surface meets the requirements.

[0043] The outer contour surface and the inner contour surface of the cold shield segment 10 are basically consistent, but since the thickness of the connecting component 13 is larger than that of the outer panel 11 and the inner panel 12, there are certain requirements for the outer contour surface of the connecting component 13. If it is too large, it will occupy a large space and will also affect the layout of other components in the nuclear fusion device. Therefore, the second measurement data is obtained by scanning the outer contour surface of the connecting component 13 outside the cold shield segment 10, and the second measurement data can be used to analyze whether the connecting component 13 meets the requirements.

[0044] In some embodiments of the present invention, reference Figure 4 The above step of "comparing the measured data with the theoretical data of the theoretical model of the cold shield segment 10 to obtain a comparison result, and determining whether the cold shield segment 10 is qualified based on the comparison result" includes: The first measurement data is compared with the theoretical data to obtain a first comparison result, and the second measurement data is compared with the theoretical data to obtain a second comparison result.

[0045] Whether the cold shield segment 10 is qualified is determined based on the first comparison result and the second comparison result.

[0046] It is understood that the theoretical data may refer to the design parameters of the theoretical model of the cold shield segment 10. In the above technical solution, the conformity of the cold shield segment 10 can be comprehensively determined based on the first measurement data of the inner contour surface of the cold shield segment 10 and the second measurement data of the outer contour surface of the connecting assembly 13 obtained by scanning. In other words, the above solution can improve the accuracy of acceptance testing by testing the manufacturing conformity of the cold shield segment 10 from two aspects.

[0047] In the above technical solution, by separately scanning the inner contour surface of the cold screen fan segment 10 and the outer contour surface of the connection component 13 and comparing them with the theoretical model, the machining errors of different parts can be detected more meticulously, avoiding overlooking local subtle errors due to overall detection. Thus, the accuracy and precision of the detection can be improved, ensuring that only the cold screen fan segment 10 meeting the high-precision requirements can be put into use and guaranteeing the reliability of the cold screen device. Usually, when the comparison result of the inner contour surface of the cold screen fan segment 10 with the theoretical model is qualified, the comparison result of the outer contour surface of the cold screen fan segment 10 with the theoretical model is also qualified, and there is no need to separately measure and detect the outer contour surface of the cold screen fan segment 10, greatly reducing the time and operation process required for detection, simplifying the detection process, and improving the detection efficiency.

[0048] In some embodiments of the present invention, referring to Figure 5 , the steps of "comparing the first measurement data with the theoretical data to obtain the first comparison result, and comparing the second measurement data with the theoretical data to obtain the second comparison result" described above include: Select a plurality of first measurement points arranged in an array on the first measurement data, compare the plurality of first measurement points with the corresponding points of the theoretical data to calculate deviations to obtain a plurality of first deviations, obtain a deviation distribution cloud map of the inner contour surface of the entire cold screen fan segment 10 through the plurality of first deviations, and display the deviation magnitudes of each region by different colors or grayscales.

[0049] Select a plurality of second measurement points arranged in an array on the second measurement data, compare the plurality of second measurement points with the corresponding points of the theoretical data to calculate deviations to obtain a plurality of second deviations, obtain a deviation distribution cloud map of the outer contour surface of the entire connection component 13 through the plurality of second deviations, and display the deviation magnitudes of each region by different colors or grayscales.

[0050] It can be understood that the first deviation may refer to the deviation between the actual parameters of the inner contour surface of the cold screen fan segment 10 and the theoretical design parameters of the corresponding points of the theoretical model, and the second deviation refers to the deviation between the actual parameters of the outer contour surface of the connection component 13 and the theoretical design parameters of the corresponding points of the theoretical model.

[0051] In the above method, due to the large volume of the cold screen fan segment 10, the size of the connection component 13 used is also large. Through the above method, the deviation between the measured actual contour and the theoretical contour can be calculated. By selecting a plurality of first measurement points arranged in an array on the first measurement data, the corresponding points of the plurality of first measurement points and the theoretical data are compared to calculate a plurality of first deviations, and a plurality of second measurement points arranged in an array are selected on the second measurement data, and the corresponding points of the plurality of second measurement points and the theoretical data are compared to calculate a plurality of second deviations. A deviation distribution cloud map is obtained through the obtained plurality of first deviations and plurality of second deviations, and the deviation sizes of each region are displayed by different colors or grayscales, so that the deviation distribution can be observed more intuitively in the first time, thereby improving the comprehensiveness of detection and the accuracy of the detection result.

[0052] In some embodiments of the present invention, referring to Figure 6 , the step of "determining whether the cold screen fan segment is qualified according to the first comparison result and the second comparison result" includes: If any one of the plurality of first deviations is greater than the first threshold, it is determined that the cold screen fan segment 10 is unqualified; If any one of the plurality of second deviations is greater than the second threshold, it is determined that the cold screen fan segment 10 is unqualified.

[0053] The "first threshold" may refer to the allowable error between the actually processed data of the cold screen fan segment 10 and the theoretically designed data. The first threshold may be a specific value or a numerical range. Similarly, the "second threshold" may refer to the allowable error between the outer contour surface data of the connection component 13 actually processed by the cold screen fan segment 10 and the theoretically designed data. The second threshold may be a specific value or a numerical range. Optionally, the "first threshold" and the "second threshold" may be 5 mm to 10 mm, or may be -5 mm to 5 mm.

[0054] For example, both the "first threshold" and the "second threshold" are 10 mm. In the first measurement data, if the first deviation between any one of the first measurement points and the corresponding point of the theoretical data is greater than 10 mm, it means that the inner contour surface of the cold screen fan segment 10 is unqualified, and there is a quality problem in the processing of the cold screen fan segment 10, and it is a defective product. In the second measurement data, if the second deviation between any one of the second measurement points and the corresponding point of the theoretical data is greater than 10 mm, it means that the outer contour surface of the connection component 13 is unqualified, and there is a quality problem in the processing of the cold screen fan segment 10, and it is a defective product.

[0055] In the above technical solution, by measuring the first deviation and the second deviation, and setting the corresponding first threshold and second threshold, the judgment standard for the processing quality of the cold screen fan segment 10 is quantified, which can make the judgment of the processing quality more objective and accurate, avoid the interference of human factors, and then ensure that when detecting at different times and by different inspectors, the judgment on whether the processing of the cold screen fan segment 10 is qualified is consistent, improving the accuracy of the detection result.

[0056] In some embodiments of the present invention, with reference to Figure 7 , the connecting component 13 is configured to have insulation, and the acceptance detection method of the cold screen device further includes: Measuring the resistance data between two adjacent outer panels 11, between two adjacent inner panels 12, and between an adjacent outer panel 11 and an inner panel 12, and comparing the resistance data with a set value to obtain a detection result.

[0057] Determine whether the cold screen fan segment 10 is qualified according to the detection result.

[0058] It can be understood that with reference to Figure 8 , the connecting component 13 may include an insulating component 131, a first flanging 132, and a second flanging 133. The first flanging 132 and the second flanging 133 are respectively arranged on both sides of the insulating component 131 and are correspondingly connected to two adjacent outer panels 11. The insulating component 131 can insulate between the outer panel 11 and the inner panel 12 connected to the connecting component 13, or between two adjacent outer panels 11, or between two adjacent inner panels 12, preventing current from being conducted to other parts that should not be electrified through the connecting component 13, and avoiding the formation of a large secondary magnetic field and secondary current on the cold screen fan segment 10. The insulating component 131 can be, but is not limited to, fiberglass resin, ceramics, etc.

[0059] In the above technical solution, the connecting component 13 is configured to have insulation. By measuring the resistance between any two adjacent panels and comparing it with the set value, it can directly detect whether the insulation effect of the connecting component 13 meets the expectation. If the resistance value meets the set value, it indicates good insulation performance, which can effectively prevent problems such as electrical short - circuit between different panels, ensuring the electrical safety and stable operation of the nuclear fusion device.

[0060] In some embodiments of the present invention, with reference to Figure 9 , the resistance data includes a first resistance between any two adjacent outer panels 11, a second resistance between any two adjacent inner panels 12, and a third resistance between the inner panel 12 and the outer panel 11; the step of determining whether the cold screen fan segment 10 is qualified according to the detection result includes: If the first resistance is less than the first set value, determine that the cold screen fan segment 10 is unqualified; If the second resistor is less than the second set value, it is determined that the cold shield fan segment 10 is unqualified; If the third resistor is less than the third set value, it is determined that the cold shield fan segment 10 is unqualified.

[0061] It can be understood that the first set value, the second set value, and the third set value can be the same or different, and can be specific numerical values or numerical ranges. Optionally, the first set value, the second set value, and the third set value are infinite resistance values. The infinite resistance value can refer to, but is not limited to, a resistance value between 10 6 ~10 14 Ω. That is to say, there is an open circuit state between the two inner panels 12, and they are insulated from each other.

[0062] In the above technical solution, the first resistor between any two adjacent outer panels 11, the second resistor between any two adjacent inner panels 12, and the third resistor between the inner panel 12 and the outer panel 11 are respectively detected and compared with the corresponding set values. For example, when any one of the first resistor, the second resistor, and the third resistor is not an infinite resistance value, it indicates that there is conduction between the two connected inner panels 12, and there is a risk of insulation failure. Therefore, it is determined that the product is unqualified. That is to say, through the above solution, the connection parts between different panels in the cold shield fan segment 10 can be comprehensively covered, ensuring a full range of detection of the insulation performance of the entire cold shield fan segment 10, without missing any area where insulation problems may exist, thereby improving the comprehensiveness and accuracy of the detection.

[0063] In some embodiments of the present invention, referring to Figure 10 , after the step of installing multiple window fixing plates 220 on the test bracket 210, the acceptance and detection method of the cold shield device further includes: Scanning the multiple window fixing plates 220 on the test bracket 210 to obtain scanning data, and comparing the scanning data with the expected parameters of the window structure of the theoretical model to obtain an analysis result; Adjusting the multiple window fixing plates 220 according to the analysis result.

[0064] In the above technical solution, scanning the multiple window fixing plates 220 on the test bracket 210 and comparing the scanning data with the expected parameters of the window structure of the theoretical model can timely detect the deviation of the window fixing plates 220 from the theoretical expectation in terms of installation position, size, etc. Adjusting the multiple window fixing plates 220 according to the analysis result can ensure that they meet the high-precision installation requirements, thereby ensuring that the window fixing plates 220 can simulate a more real and accurate support and stress state for the cold shield fan segment 10, and further improving the accuracy of the detection of the cold shield fan segment 10.

[0065] In some embodiments of the present invention, the scanned data includes the first shape parameters and the first position parameters of a plurality of window fixing plates 220 on the test bracket 210, and the expected parameters include the second shape parameters and the second position parameters of the window structure in the theoretical model. Refer to Figure 11 , the step of "adjusting a plurality of window fixing plates 220 according to the analysis result" described above includes: If the deviation between the first shape parameter and the second shape parameter is greater than the fourth threshold, it is determined that the window fixing plate 220 is unqualified, and the qualified window fixing plate 220 is replaced; If the deviation between the first position parameter and the second position parameter is greater than the fifth threshold, it is determined to adjust the positions of the plurality of window fixing plates 220 on the test bracket 210.

[0066] The "fourth threshold" may refer to the allowable error between the actually scanned graphic data of the cold screen fan segment 10 and the design data of the window structure in the theoretical model. For example, the fourth threshold may refer to the deviation between the shape and size of each window fixing plate 220 and the corresponding window structure in the theoretical model of the cold screen fan segment 10.

[0067] The "fifth threshold" may refer to the allowable error between the position information between the actually scanned plurality of window fixing plates 220 of the cold screen fan segment 10 and the design position parameters between the plurality of window structures in the theoretical model. For example, referring to Figure 1 and Figure 2 , the fifth threshold may refer to the allowable error between the relative positions of the three window fixing plates 220 in the up-down direction, the front-back direction, and the left-right direction and the relative positions of the plurality of window structures in the theoretical model.

[0068] In the above technical solution, when the deviation between the first shape parameter and the second shape parameter is greater than the fourth threshold, replacing the qualified window fixing plate 220 can ensure that the used window fixing plate 220 meets the design requirements in terms of external dimensions, and avoid problems such as structural mismatch and inaccurate window dimensions after the cold screen fan segment 10 is assembled, thus ensuring the assembly quality of the cold screen fan segment 10 from the source. When the deviation between the first position parameter and the second position parameter is greater than the fifth threshold, adjusting the positions of the plurality of window fixing plates 220 on the test bracket 210 until the deviation is less than the fifth threshold can make the positions of the window fixing plates 220 on the test bracket 210 highly consistent with the theoretical model, providing an accurate reference for the subsequent assembly of each component of the cold screen fan segment 10, thereby improving the assembly accuracy of the cold screen fan segment 10 and reducing the component installation errors caused by the position deviation of the window fixing plate 220.

[0069] In some embodiments of the present invention, such as Figure 12As shown, the acceptance testing method of the cold shield device includes: detecting the magnetic permeability of the cold shield sector 10, comparing the detected first magnetic permeability with the preset magnetic permeability to determine whether the cold shield sector 10 is qualified; detecting the roughness of the cold shield sector 10, comparing the detected first roughness with the preset roughness to determine whether the cold shield sector 10 is qualified; detecting the leakage of the cooling pipeline of the cold shield sector 10, and determining whether the cold shield sector 10 is qualified according to the detected leakage situation.

[0070] It can be understood that in addition to the detection process of the above embodiments, the acceptance testing method of the cold shield device can also detect the magnetic permeability of the cold shield sector 10. The first magnetic permeability can refer to the magnetic permeability actually measured on site, and the preset magnetic permeability can refer to the magnetic permeability of qualified products. The preset magnetic permeability can be a specified value or a range. If the first magnetic permeability does not meet the preset magnetic permeability, it means that the magnetic permeability of the cold shield sector 10 is unqualified, so the cold shield sector 10 is also unqualified.

[0071] The cold shield sector 10 is required to have a polished surface and a low surface roughness in order to resist thermal radiation and have a good thermal shielding effect. Therefore, the present invention can also detect the roughness of the cold shield sector 10. The first roughness can refer to the roughness actually measured, and the preset roughness can refer to the roughness of qualified products. The preset roughness can be a fixed value or a range. If the first roughness does not meet the preset roughness, it means that the measured roughness of the cold shield sector 10 does not meet the requirements, so the cold shield sector 10 is unqualified.

[0072] Furthermore, after the cold shield sector 10 is delivered, a cooling pipeline will be set on the surface, and the leakage of the cooling pipeline can also be detected. If a leak point is detected in the cooling pipeline, it means that the cooling pipeline is unqualified and the cold shield sector 10 is also unqualified.

[0073] It should be noted that the method steps of this embodiment have no sequential relationship with the steps of the profile detection and insulation detection described above and can be combined with each other, and no specific limitation is made here. Exemplarily, the order of the method steps of the acceptance testing method of the cold shield device in this embodiment can refer to Figure 12 .

[0074] Next, in combination with the attached Figure 12 , a specific embodiment of the acceptance testing method of the cold shield device of the present invention will be described.

[0083] Step Eight: Detection of sector pipeline leakage, specifically including: detecting the leakage of the cooling pipeline of the cold shield segment 10, and judging whether the cold shield segment 10 is qualified according to the detected leakage situation.

[0084] Reference Figure 13, An acceptance detection device 200 for a cold screen device according to an embodiment of the present invention is used to apply the acceptance detection method of the cold screen device in any of the previous embodiments. The device includes: a test bracket 210, a window fixing plate 220, a scanning component 230, and a control component 240. There are multiple window fixing plates 220 which are arranged on the test bracket 210 and are used to assemble the outer panel 11, the inner panel 12, and the connecting component 13 to form the cold screen fan segment 10. The scanning component 230 is used to scan the cold screen fan segment 10. The control component 240 is electrically connected or communicatively connected to the scanning component 230, and is used to obtain the measurement data of the scanning component 230, compare the outer contour with the theoretical model of the cold screen fan segment 10 to obtain a comparison result, and determine whether the processing of the cold screen fan segment 10 is qualified according to the comparison result.

[0085] The multiple window fixing plates 220 can accurately assemble the outer panel 11, the inner panel 12, and the connecting component 13 on the test bracket 210, ensuring the accurate relative positions between the components, and improving the assembly accuracy of the cold screen fan segment 10. A stable assembly reference helps to reduce quality problems caused by assembly errors and improve the consistency of product quality.

[0086] The scanning component 230 can be, but is not limited to, a three-dimensional scanner, a three-dimensional lidar, a structured light three-dimensional scanning instrument, etc. The scanning component 230 can also be, but is not limited to, a handheld type, a fixed type, a mobile type, etc.

[0087] The control component 240 can be understood as a control host, and can be, but is not limited to, a computer, etc.

[0088] For the acceptance detection device 200 of the cold screen device according to an embodiment of the present invention, the combined use of the scanning component 230 and the control component 240 realizes the rapid scanning and accurate comparative analysis of the outer contour of the cold screen fan segment 10. Compared with the traditional detection method, this automated detection method greatly improves the detection efficiency. At the same time, it can reduce the interference of human factors, improve the accuracy of the detection results, prevent unqualified products from entering the subsequent links, save time and cost, and can realize the quality control in the manufacturing and acceptance handover process of the cold screen device.

[0089] In some embodiments of the present invention, the acceptance detection device 200 of the cold screen device further includes an adjustment mechanism 250. Each window fixing plate 220 is installed on the test bracket 210 through the adjustment mechanism 250. The scanning component 230 may be used to measure the multiple window fixing plates 220 on the test bracket 210 to obtain scanning data. The control component 240 is electrically connected or communicatively connected to the adjustment mechanism 250, and is used to compare the scanning data with the expected parameters of the window structure of the theoretical model to obtain an analysis result, and control the adjustment mechanism 250 to adjust the multiple window fixing plates 220 according to the analysis result.

[0090] The adjustment mechanism 250 can be a device capable of moving along the X-axis, Y-axis, and Z-axis, and can be, but not limited to, a three-axis stage, a robotic arm, etc. Exemplarily, the adjustment mechanism 250 can include three adjustment components, and the three adjustment components can be adjusted along the X-axis, Y-axis, and Z-axis respectively, that is, move and adjust along the left-right direction, front-back direction, and up-down direction. The adjustment components can be, but not limited to, adjustment screws, linear motors, cylinders, etc.

[0091] In the above technical solution, the scanning component 230 can also be used to scan a plurality of window fixing plates 220 to obtain the shape and position parameter information of the plurality of window fixing plates 220. After the control component 240 compares these scanning data with the expected parameters of the plurality of window structures in the theoretical model of the cold screen segment 10, it can be learned whether the shape of the plurality of window fixing plates 220 is consistent with the window structure, so as to replace the window fixing plates 220 with non-conforming shapes according to the analysis results. The control component 240 can also learn from the scanning data whether the positions of the plurality of window fixing plates 220 are consistent with the positions of the plurality of window structures in the theoretical model, and control the adjustment mechanism 250 to precisely adjust the plurality of window fixing plates 220 according to the comparison structure, which can ensure that the plurality of window fixing plates 220 can more accurately simulate the support and stress states of the cold screen segment 10 in the real scenario, provide a high-precision reference for the subsequent assembly of the cold screen segment 10, and thus improve the accuracy of the acceptance inspection of the cold screen segment 10.

[0092] The acceptance inspection method of the cold screen device according to the embodiment of the present invention has the following advantages: 1. Scan and compare the inner contour surface of the cold screen segment 10 and the outer contour surface of the connection component 13 respectively, and at the same time measure the shape and position parameters of the window fixing plate 220 and compare them with the theoretical values. Detect the cold screen device from components to the whole, multi-dimensionally and comprehensively, and can more comprehensively discover the problems existing in the processing and assembly processes, ensuring the overall quality of the cold screen device.

[0093] 2. Quantitatively determine the processing quality of the cold screen device by accurately measuring the parameters of each part (such as the shape contour deviation of different parts, the resistance between different panels, etc.) and comparing them with strictly set thresholds or expected parameters. Can accurately identify subtle deviations and defects, ensuring that the cold screen device meets the strict requirements of high precision for nuclear fusion devices.

[0094] 3. Use the scanning component 230 to scan and obtain data, and the control component 240 performs data processing, analysis, and control, which can realize an automated process from measurement, data processing to result determination. Reduce manual operation and human error, thereby improving the detection efficiency, quickly obtaining a conclusion on whether the cold screen device is qualified, accelerating the acceptance inspection process, and meeting the time requirements of production and use.

[0095] 4. During the testing process, record in detail data such as measurement information, analysis results, and comparison results, providing rich and accurate data support for the quality traceability of the cold shield device. Once problems occur in the subsequent use of the cold shield device, these data can be used to quickly trace back to specific processing, assembly, or inspection links, facilitating the accurate analysis of the causes of problems and the timely adoption of effective improvement measures.

[0096] 5. Strict acceptance testing methods ensure the high quality of the cold shield device, effectively excluding products with potential quality hazards, reducing the risk of operation accidents of the nuclear fusion device caused by cold shield device failures, and ensuring the safety of personnel and equipment.
