Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of fusion reactors, in particular to an assembly tool and an assembly method for a divertor. BACKGROUND

[0002] The divertor is one of the important components of a fusion device (for example, a common tokamak device). The divertor is generally divided into a target plate and a body according to its own function and structure. The target plate is a component that bears high heat load when the divertor faces the plasma, and the target plate includes an inner target plate, an outer target plate, and a DOME plate. The body is an important load-bearing component for supporting the target plate and transferring electromagnetic force. The common existing divertor usually adopts a box body (divertor box) as the body, the box body has an irregular shape, and the box body has an inner side surface and an outer side surface arranged oppositely; the inner target plate, the DOME plate, and the outer target plate are sequentially mounted to the inner side surface of the box body along the extension direction of the box body, and the box body is connected to the fusion device through the outer side surface thereof.

[0003] The inner target plate, the outer target plate, and the DOME plate are tungsten-copper assembly pieces with tungsten on the surface and cooling channels inside; when the fusion device is working, the target surface (i.e., the tungsten-coated surface) of the target plate directly faces the plasma, and the profile shape of the tungsten surface is directly related to the plasma discharge shape; therefore, it is necessary to ensure that the profile degree of the target surface of the target plate of the divertor is within the error allowable range, so as to effectively guarantee the normal work of the divertor.

[0004] However, in the existing assembly process of the box body and the target plate, there is a lack of an assembly tool that can serve as an assembly reference, which makes it difficult to determine a suitable reference for profile detection of the target plate after the target plate is installed to the box body, thereby resulting in poor assembly precision and ultimately affecting the normal work of the divertor.

[0020] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0021] like Figures 1-3 As shown, an assembly fixture 2 for a divertor according to an embodiment of the present invention includes a reference component 21 and a positioning component 22. The reference assembly 21 includes a first reference plate 211 and a second reference plate 212. The first reference plate 211 is horizontally arranged, and the second reference plate 212 is vertically arranged and fixedly connected to the first reference plate 211. The first reference plate 211 has a first reference surface 2101, and the second reference plate 212 has a second reference surface 2102 that is perpendicular to the first reference surface 2101. The positioning component 22 includes a first positioning block 221, a second positioning block 222, and a third positioning block 223 arranged sequentially at intervals along the length of the first reference plate 211; the second positioning block 222 and the third positioning block 223 are fixed to the upper surface of the first reference plate 211, and the first positioning block 221 is fixed to the side surface of the second reference plate 212 opposite to the second positioning block 222; the side surface of the first positioning block 221 opposite to the second positioning block 222 defines a first positioning surface 2201, the upper surface of the second positioning block 222 defines a second positioning surface 2202, and the upper surface of the third positioning block 223 defines a third positioning surface 2203; The first positioning surface 2201, the second positioning surface 2202, and the third positioning surface 2203 are respectively set to correspond one-to-one with the mounting surface of the divertor housing to the fusion device.

[0022] According to the technical scheme, the first positioning surface 2201, the second positioning surface 2202 and the third positioning surface 2203 of the positioning assembly 22 are used to position and fix the box body 11 of the deflector to the assembly tool 2, and then the installation and fixation of the target plate 12 and the box body 11 are facilitated; the first reference surface 2101 and the second reference surface 2102 are perpendicular to each other, so that when the box body of the deflector and the target plate are assembled and the profile of the target plate of the deflector is detected, the reference coordinate system can be set by using the first reference surface 2101 and the second reference surface 2102, and then the profile of the target plate 12 is detected and adjusted by taking the reference coordinate system as a reference, so that the profile of the target plate 12 of the deflector assembled by using the assembly tool 2 meets the error allowance, and then the deflector assembled by using the assembly tool 2 has sufficient assembly precision.

[0023] Preferably, as shown in the embodiment, the upper surface of the first reference plate 211 defines the first reference surface 2101, and the side surface of the second reference plate 212 opposite to the second positioning block 222 defines the second reference surface 2102. The two reference surfaces perpendicular to each other can form a reference coordinate system after the origin is defined, so as to detect the target plate 12. Figures 1-3

[0024] Further, as shown in the embodiment, the second reference plate 212 is fixedly provided with the first reinforcing rib 231 and the second reinforcing rib 232 on both sides in the length direction of the first reference plate 211, and the second reinforcing rib 232 is fixedly connected to the second positioning block 222 away from the second reference plate 212. The first reinforcing rib 231 and the second reinforcing rib 232 are fixedly connected to the first reference plate 211. Figures 1-3

[0025] It can be understood that since the second reference plate 212 is vertically arranged and fixedly connected to the first reference plate 211, in order to improve the reliability of the second reference plate 212 and prevent the reliability of the second reference surface 2102 from being damaged due to slight bending or tilting of the second reference plate 212, the first reinforcing rib 231 and the second reinforcing rib 232 are arranged on both side surfaces in the stress direction of the second reference plate 212, and the stress of the second reference plate 212 is transmitted to the horizontally arranged first reference plate 211 through the first reinforcing rib 231 and the second reinforcing rib 232. The second reinforcing rib 232 is also connected to the second positioning block 222, so as to ensure the relative position precision of the first positioning surface 2201 and the second positioning surface 2202, provide a positioning assembly position with good precision for the box body 11, and help to improve the overall assembly precision of the deflector 1.

[0026] Further, as shown in the embodiment, the second reference plate 212 is fixedly provided with the first reinforcing rib 231 and the second reinforcing rib 232 on both sides in the length direction of the first reference plate 211, and the second reinforcing rib 232 is fixedly connected to the second positioning block 222 away from the second reference plate 212. The first reinforcing rib 231 and the second reinforcing rib 232 are fixedly connected to the first reference plate 211. Figures 1-3 ​​As shown, the second positioning block 222 is fixed with a third reinforcing rib 233 on the side away from the second reference plate 212, and the third positioning block 223 is fixed with a fourth reinforcing rib 234 and a fifth reinforcing rib 235 on the two sides in the length direction of the first reference plate 211 respectively. The third reinforcing rib 233, the fourth reinforcing rib 234 and the fifth reinforcing rib 235 are fixedly connected with the first reference plate 211.

[0027] It can be understood that the third reinforcing rib 233 is arranged to make the two sides of the second positioning block 222 in the length direction of the first reference plate 211 have reinforcing structures, and the fourth reinforcing rib 234 and the fifth reinforcing rib 235 are arranged to make the two sides of the third positioning block 223 in the length direction of the first reference plate 211 have reinforcing structures.

[0028] Further, as shown in the figure, Figure 3 The assembly tool 2 further comprises a compensation assembly 24. The compensation assembly 24 is arranged above the third positioning block 223 and detachably connected with the third positioning block 223, and the compensation assembly 24 is used to form a fourth positioning surface 2204 arranged above the third positioning surface 2203.

[0029] It can be understood that the assembly of the bias filter 1 includes the assembly of the box body 11 and the target plate 12 and the connection of the cooling flow channels in the target plate 12. Since the cooling flow channels are arranged inside the target plate 12 and the water inlet and outlet and the target surface are located on the opposite sides, the operation space for connecting the cooling flow channels is small. By arranging the compensation assembly 24, the assembly tool 2 has the fourth positioning surface 2204 arranged above the third positioning surface 2203, which facilitates lifting the box body 11 based on the original position to reserve sufficient operation space.

[0030] Further, as shown in the figure, Figure 3 The compensation assembly 24 comprises a compensation pipe 241 and a compensation plate 242. The compensation pipe 241 is vertically arranged, and the two ends of the compensation pipe 241 are fixedly provided with the compensation plate 242. The compensation pipe 241 is detachably connected with the third positioning block 223 through the compensation plate fixedly arranged at the bottom end of the compensation pipe 241, and the upper surface of the compensation plate fixedly arranged at the top end of the compensation pipe 241 defines the fourth positioning surface 2204.

[0031] Preferably, in order to ensure better overall balance of the assembly fixture 2, so as to avoid tipping over due to uneven force on the assembly fixture 2 during the assembly of the box 11 and the target plate 12 which have a certain weight and size; the center line of the first reference plate 211 and the center line of the second reference plate 212 are in the same plane.

[0032] It should be noted that the first reference plate 211 and the second reference plate 212 are usually square plates to facilitate processing or acquisition, and have a larger contact area and better balance. Since the first positioning block 221 is fixed on one side surface of the second reference plate 212, by making the center line of the first reference plate 211 and the center line of the second reference plate 212 in the same plane, the center of gravity projection of the reference assembly 21 as a whole falls on the center line of the first reference plate 211, so that the overall balance of the reference assembly 21 is better.

[0033] Similarly, the center lines of the first positioning block 221, the second positioning block 222, and the third positioning block 223 are all located in the same plane. Furthermore, in this embodiment, the center line of the first reference plate 211 and the center line of the first positioning block 221 are located in the same plane, so that the assembly fixture 2 as a whole has better balance.

[0034] like Figure 9 As shown, the present invention also provides a method for assembling a divertor, using the assembly fixture 2 described above, comprising the following steps: S1. Install the mounting surfaces of the housing 11 onto the first positioning surface 2201, the second positioning surface 2202 and the third positioning surface 2203 respectively; S2. Initially position the target plate 12 and the box body 11; S3. Establish a reference coordinate system using the first reference plane 2101 and the second reference plane 2102 as references through a laser tracker; S4. Establish the actual contour of the target surface of the target plate 12 in the reference coordinate system using a laser tracker; S5. Compare the actual contour of the target surface with the ideal contour of the target surface; If the deviation between the actual contour and the ideal contour is less than or equal to the upper limit of the allowable error value, fix the target plate to the box body. If the deviation between the actual contour and the ideal contour is greater than the upper limit of the allowable error value, adjust the position of the target plate until the deviation between the actual contour and the ideal contour is less than or equal to the upper limit of the allowable error value. S6. Connect multiple cooling channels in the target plate to form a series cooling channel; S7. Perform a leak test on the cooling channel of the divertor.

[0035] Based on the above technical scheme, the box body 11 is installed to the assembly tool 2 through the first positioning surface 2201, the second positioning surface 2202 and the third positioning surface 2203, and then the target plate 12 is preliminarily positioned with the box body 11; the first reference surface 2101 and the second reference surface 2102 of the assembly tool 2 are used to cooperate with the laser tracker to establish a reference coordinate system, to obtain an actual profile of the target surface of the target plate 12, to compare the deviation of the actual profile with an ideal profile with an allowable error value, and to further adjust the target plate 12 or to fixedly connect the target plate 12 to the box body 11 according to the comparison result; finally, a plurality of cooling channels in the target plate 12 are connected to form a series cooling channel, so as to obtain a final product of the divertor with high assembly precision, and to effectively ensure the normal work of the divertor; and a leakage test is performed to ensure that the cooling channel can normally perform the cooling work.

[0036] Further, as shown in Figure 1 and Figure 2 to specifically realize the obtaining of the actual profile of the target surface of the target plate 12, the actual profile of the target surface of the target plate 12 in the reference coordinate system is established by the laser tracker in the step S4, and specifically includes: The coordinate values of a plurality of points on the target surface of the target plate 12 in the reference coordinate system are collected by the laser tracker; and the actual profile of the target surface of the target plate 12 in the reference coordinate system is fitted by the plurality of coordinate values.

[0037] Further, as shown in Figure 8 Since the shapes of the two sides of the divertor 1 also need to meet certain precision requirements to avoid interference when a plurality of divertors 1 are installed in a circumferential array to the fusion device, the shapes of the two sides of the divertor 1 need to be detected for precision; the step S7 includes the following steps before the step S7: S7-0, the assembled divertor 1 is detached from the assembly tool 2; The three divertors 1 are installed to the shape detection tool 4; the shape detection tool 4 is provided with an installation space for simulating the continuous installation of a plurality of divertors 1 to the fusion device, and the installation space includes a plurality of installation sites which are concentrically arranged and sequentially arranged in the annular direction; The three divertors 1 are sequentially installed on the three continuous installation sites, the gap value between the adjacent two divertors 1 is detected, and the gap value between the two shapes of the two divertors 1 is detected by interchanging the positions of any two divertors 1; If the gap value is within the range of the allowable gap value, it is considered that the shape precision of the divertor participating in the detection is qualified; if the gap value is not within the range of the allowable gap value, it is considered that the shape precision of the divertor participating in the detection is unqualified.

[0038] It can be understood that the gap value between the two side shapes of any two deflection filters 1 is exchanged to improve the detection efficiency of the two side shapes of the plurality of deflection filters 1, and through the exchange installation, whether there is interference between the adjacent two deflection filters 1 can quickly screen out the deflection filter with larger deviation in the shape, thereby effectively improving the shape detection efficiency.

[0039] It should be noted that the gap value between the two side shapes of any two deflection filters is specifically: the three deflection filters installed for the first time are defined as a first deflection filter, a second deflection filter and a third deflection filter from left to right, and the second deflection filter and the third deflection filter are adjacent, so the gap value between the right side shape of the second deflection filter and the left side shape of the third deflection filter can be measured; the positions of the second deflection filter and the third deflection filter are exchanged, so that the right side shape of the third deflection filter is adjacent to the left side shape of the second deflection filter, and the corresponding gap value is measured, thereby realizing the detection of the gap value between the two side shapes of the second deflection filter and the third deflection filter.

[0040] Preferably, in the embodiment, the allowed gap value d is defined as 0 < d < 0.6 mm to ensure the accuracy of the two side shapes of the deflection filter 1.

[0041] Preferably, in the step S1, the mounting surface of the box body 11 is correspondingly mounted to the first positioning surface 2201, the second positioning surface 2202 and the third positioning surface 2203, and specifically includes: S1-1, placing the assembly tool 2 on the mounting platform; The horizontal degree and vertical degree of the assembly tool 2 are checked through the first reference surface 2101 and the second reference surface 2102; S1-2, after adjusting the assembly tool 2 to meet the requirements of horizontal degree and vertical degree, the assembly tool 2 is fixedly connected to the mounting platform; S1-3, placing the box body 11 to the assembly tool 2; S1-4, adjusting the box body 11 until the projection of the center line thereof in the vertical direction coincides with the projection of the center line of the reference assembly 21 in the vertical direction; S1-5, fixedly connecting the mounting surface of the box body 11 to the first positioning surface 2201, the second positioning surface 2202 and the third positioning surface 2203.

[0042] It can be understood that, in combination with the installation platform, the first reference surface 2101 and the second reference surface 2102, the horizontal degree and the vertical degree of the assembly tool 2 are checked, and a basis for establishing a reference coordinate system with high precision is established.
