Description

Technical Field

[0001] This invention relates to the field of radiation detection technology, and in particular to an assembly method and assembly apparatus for assembling multiple detection modules into a conduit of an irradiation device. Background Technology

[0002] In activation experiments, an irradiation device equipped with detector plates is needed to measure key core parameters such as axial and radial reaction rate distributions and energy spectra. During the fabrication of the irradiation device, multiple detector plates need to be assembled at specific detection positions within the irradiation device's duct according to experimental requirements. Summary of the Invention

[0003] One aspect of this application provides an assembly method for assembling multiple detection modules into a conduit of an irradiation device. Each detection module includes multiple detector pieces stacked axially and a foil covering the outer side of the detector pieces. The method includes: arranging the multiple detection modules at intervals along the axial direction; providing multiple positioning blocks, placing a positioning block between adjacent detection modules to position each detection module in its respective preset axial position; pressing the multiple detection modules and positioning blocks axially to compact the multiple detection modules; aligning one side port of the conduit with the multiple detection modules; and sequentially pushing the multiple detection modules and positioning blocks axially into the conduit.

[0004] Another aspect of this application provides an assembly apparatus for assembling multiple detection modules into a conduit of an irradiation device. Each detection module includes multiple detector pieces stacked axially and a foil covering the outer side of the detector pieces. The assembly apparatus includes: a first base for placing the conduit; a second base coaxially arranged with the first base for axially spaced multiple detection modules; multiple positioning blocks for separating adjacent detection modules so that each detection module is positioned in its respective preset axial position; a first clamping part detachably mounted on the side of the second base facing the first base; and a second clamping part configured to slide relative to the second base in a direction away from or near the first clamping part, thereby axially pressing the multiple detection modules and multiple positioning blocks by sliding the second clamping part relative to the second base towards the first clamping part, thus compacting the multiple detection modules.

[0005] The assembly method of this application embodiment uses positioning blocks to position each detection module, and then compresses each detection module and each positioning block along the axial direction, so that the foil of the detection module is compacted. After the arranged detection modules and positioning blocks are placed into the conduit in sequence, when the axis of the conduit is in the vertical direction, the detection module will not be able to move along the axial direction in the conduit, thereby avoiding the detection module from deviating from its corresponding detection position and avoiding damage to the detection module.

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this invention. Obviously, the described embodiments are one embodiment of this invention, and not all embodiments. Based on the described embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0025] It should be noted that, unless otherwise defined, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this invention pertains.

[0026] In the description of the embodiments of the present invention, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0027] In related technologies, multiple detector plates inside the conduit are needed to detect different locations within the reactor. The conduit of the irradiation device has a relatively small and long inner diameter, making it very difficult to position each detector plate at a specific detection location when pouring it into the conduit.

[0028] To address the aforementioned issues, the inventors of this application utilize foil to wrap several detector pieces into a single detector module. Each detector module is placed at a corresponding detector position within the conduit. This makes it more convenient to introduce or remove the detector module from the conduit, facilitating placement of the detector module at a specific detector position within the conduit and increasing the number of detector pieces at the same detector position, thereby improving detection accuracy.

[0029] Furthermore, wrapping the detector with foil can reduce the degree of oxidation of the detector in air. The foil can be, for example, aluminum foil.

[0030] However, in actual detection processes, after the detection is completed, the detection module may deviate from its detection position, and some detection modules may be damaged, thus becoming stuck in the conduit and difficult to be discharged smoothly, increasing the radiation dose to the operators.

[0031] The inventors of this application discovered that although the detection module is in its detection position when placed in the conduit, the foil of the detection module may be slightly loose. During the detection process, as the conduit is moved multiple times in a vertical position, the foil of the detection module inside the conduit is compressed or tightened under the action of gravity, resulting in empty areas inside the conduit. This allows the detection module to move axially in the conduit, causing some detection modules to deviate from their corresponding detection positions and potentially become damaged.

[0032] To address the aforementioned issues, this application provides an assembly method and apparatus for assembling multiple detection modules into a conduit of an irradiation device. Each detection module includes multiple detector pieces stacked axially and a foil covering the outer surface of the detector pieces. The assembly method and apparatus of this application can position and compact each detection module outside the conduit, preventing axial movement within the conduit after placement, thus avoiding deviation from the corresponding detection position and preventing damage to the detection modules.

[0033] See Figure 1 and Figure 2 This invention provides an assembly apparatus for assembling multiple detection modules 60 into a conduit 30 of an irradiation device. Each detection module 60 includes multiple detector pieces stacked axially and a foil covering the outer side of the detector pieces. The assembly apparatus includes a first base 10, a second base 20, multiple positioning blocks 70, a first clamping part 40, and a second clamping part 50.

[0034] The first base 10 is used to place the conduit 30. The second base 20 is coaxially arranged with the first base 10 and is used to arrange multiple detection modules 60 at axial intervals. Multiple positioning blocks 70 are used to separate two adjacent detection modules 60 so that each detection module 60 is in its respective preset position along the axial direction. The first clamping part 40 is detachably mounted on the side of the second base 20 facing the first base 10. The second clamping part 50 is configured to slide relative to the second base 20 in a direction away from or towards the first clamping part 40, thereby axially pressing the multiple detection modules 60 and the multiple positioning blocks 70 by sliding the second clamping part 50 relative to the second base 20 towards the first clamping part 40, so as to compact the multiple detection modules 60.

[0035] The assembly device of this application uses positioning blocks 70 to position each detection module 60, and then uses first clamping part 40 and second clamping part 50 to clamp each detection module 60 and each positioning block 70 as a whole, so that the foil of the detection module 60 is compacted. After the arranged detection modules 60 and positioning blocks 70 are placed into the guide tube 30 in sequence, when the axis of the guide tube 30 is in the vertical direction, the detection module 60 will not be able to move axially in the guide tube 30, thereby avoiding the detection module 60 from deviating from its corresponding detection position and avoiding damage to the detection module 60.

[0036] In some embodiments, see Figure 1 The first base 10 and the second base 20 can be integrally formed. In other embodiments, see [reference needed]. Figure 2The first base 10 and the second base 20 can be configured as separate units, that is, the first base 10 and the second base 20 are two independent structures. The advantage of integral molding is that it is easy to process, while the advantage of separate units is that they are easy to disassemble and move.

[0037] In some embodiments, the positioning block 70 is used to define the position of the detection module 60. The diameter of the positioning block 70 may be substantially the same as the diameter of the detection module 60. In some embodiments, the axial length of the positioning block 70 may be 5 cm or 10 cm, etc.

[0038] To reduce weight, the positioning block 70 can be designed as a hollow metal cylinder. The metal cylinder can be made of stainless steel or aluminum to avoid introducing moderating materials.

[0039] During testing, the inside of the conduit needs to be evacuated first, followed by the injection of a protective gas (such as helium). During this process, the hollow positioning block 70 may break, causing air leakage and oxidation of the probe, thus affecting the final test results. In some embodiments, the positioning block 70 has a through-hole along its axial direction. In such embodiments, the through-hole allows for evacuation of the inside of the positioning block 70 and the conduit 30. Furthermore, during the injection of protective gas into the conduit 30, the through-hole facilitates the diffusion of the protective gas within the conduit 30, thereby preventing the positioning block 70 from introducing air into the conduit 30 and causing oxidation of the probe.

[0040] See Figure 4 In some embodiments, the upper surface of the first base 10 forms a first arcuate groove 11 that matches the surface of the conduit 30, and the first arcuate groove 11 extends axially through the upper surface of the first base 10. See also Figure 3 and Figure 4 A second arc-shaped groove 21 is formed on the upper surface of the second base 20. The second arc-shaped groove 21 is adapted to the surface of the detection module 60 and extends axially through the upper surface of the second base 20. The conduit 30 can be placed in the first arc-shaped groove 11, and the positioning block 70 and the detection module 60 can be placed in the second arc-shaped groove 21, thereby preventing the conduit 30, the positioning block 70, and the detection module 60 from rolling.

[0041] In order to place the positioning block 70 and the detection module 60 into the conduit 30, the outer diameter of the positioning block 70 and the detection module 60 is smaller than the inner diameter of the conduit 30, and correspondingly, the diameter of the second arc groove 21 is smaller than the diameter of the first arc groove 11.

[0042] In some embodiments, there is a height difference between the second arcuate groove 21 and the first arcuate groove 11, and this height difference is greater than the thickness of the conduit 30, so as to make it easier to push the detection module 60 and the positioning block 70 into the conduit 30. The second arcuate groove 21 and the first arcuate groove 11 can be coaxial.

[0043] In some embodiments, the second base 20 is provided with a scale for calibrating distance along the axial direction. The scale may be set on one side of the width direction of the second arcuate groove 21, for example. By setting the scale, precise positioning of each detection module 60 can be achieved.

[0044] In some embodiments, the scale division value can be, for example, 1 mm. In some embodiments, the end of the second arc-shaped groove 21 facing the first arc-shaped groove 11 can be the zero point of the scale. When arranging the detection module 60 on the second arc-shaped groove 21, each detection module 60 can be placed in its corresponding detection position according to the scale. Positioning blocks 70 can be inserted between two adjacent detection modules 60 for positioning. Then, the second clamping part 50 and the first clamping part 40 are used to axially press each detection module 60 and each positioning block 70 to compact the detection module 60, so as to determine whether the compacted detection module 60 is in its corresponding detection position.

[0045] See Figure 7 In some embodiments, the assembly apparatus may further include a pusher rod 80 for pushing a plurality of detection modules 60 and a plurality of positioning blocks 70 arranged on the second base 20 from the second base 20 into the conduit 30. After the detection modules 60 are compacted, the first clamping part 40 and the second clamping part 50 can be removed from the second base 20 so that the pusher rod 80 can be used to push the plurality of detection modules 60 and a plurality of positioning blocks 70 arranged on the second base 20 from the second base 20 into the conduit 30.

[0046] The booster rod 80 can be a cylinder. The diameter of the booster rod 80 is smaller than the inner diameter of the conduit 30 and larger than the outer diameter of the positioning block 70 and the detection module 60. The booster rod 80 can be formed from a single, continuous cylinder. In some embodiments, the booster rod 80 can also be composed of multiple cylindrical segments connected together, which makes it easier to carry after disassembling each segment. Adjacent cylindrical segments can be connected, for example, by threads.

[0047] In some embodiments, the pusher rod 80 is provided with a scale for calibrating distance along its axis. After pushing all the detection modules 60 and all the positioning blocks 70 into the conduit 30 using the pusher rod 80, the distance between the detection module 60 closest to the opening of the conduit 30 and the opening of the conduit 30 can be determined according to the scale of the pusher rod 80, so as to leave space for the end to be inserted into the conduit 30 and ensure that the end of the irradiation device is smoothly connected to the conduit 30.

[0048] In some embodiments, the assembly device may further include a shim. After the second clamping part 50 and the first clamping part 40 axially compress each detection module 60 and each positioning block 70, the axial length of the detection module 60 may be slightly reduced, resulting in a reduction in the distance between some detection modules 60 and the zero point, causing the detection modules 60 to deviate significantly from their preset detection positions. In such embodiments, the positions of the detection modules 60 that are closest to the zero point and significantly deviate from their preset detection positions can be fine-tuned first. For ease of description, the direction along the axial direction of the second arcuate groove 21 towards the zero point is called "front," and the direction away from the zero point is called "rear." A shim can be inserted between the detection module 60 and the detection module 60 adjacent to its front side. The function of the shim is to fine-tune the position of the detection module 60. The thickness of the shim is relatively thin, much smaller than the axial length of the positioning block 70. In some embodiments, the thickness of the positioning block 70 can be 5cm-10cm, while the thickness of the shim can be 1mm-2mm.

[0049] In some embodiments, the second base 20 has a first insertion portion extending in a direction perpendicular to the axial direction at one end facing the first base 10. The first clamping portion 40 includes a first clamping plate 41 and a first insertion mating portion connected to the first clamping plate 41. The first clamping portion 40 is detachably mounted on the second base 20 through the insertion and mating of the first insertion portion and the first insertion mating portion.

[0050] In some embodiments, the second base 20 forms first insertion portions on both sides of the second arcuate groove 21 along its width direction; correspondingly, the first clamping plate 41 forms first insertion mating portions on both sides of its width direction.

[0051] See Figure 4 The first insertion portion may include first insertion slots 12 extending vertically from both sides of the second base 20 in the width direction; see also Figure 5 The first insertion mating part may include a first insertion plate 43 that extends vertically and is connected to both sides of the first clamping plate 41 along the width direction. The first insertion plate 43 is arranged parallel to the first clamping plate 41.

[0052] Furthermore, the first insertion portion may also include a second insertion groove 13 extending vertically from both sides of the second base 20 in the width direction. The second insertion groove 13 is connected to the first insertion groove 12, and the groove depth of the second insertion groove 13 in the width direction of the second base 20 is less than the groove depth of the first insertion groove 12 in the width direction of the second base 20.

[0053] Correspondingly, the first insertion mating part may further include a vertically extending second insertion plate 42 connected to both sides of the first clamping plate 41 along its width direction, the second insertion plate 42 being perpendicular to the first insertion plate 43 and the first clamping plate 41. The first insertion plate 43 and the first clamping plate 41 are connected by the second insertion plate 42. In this embodiment, the insertion and mating of the first insertion part and the first insertion mating part enable the first clamping plate 41 to be stably connected to the second base 20. The surface of the first clamping plate 41 facing the second clamping plate 51 may be located at the zero point position on the second base 20.

[0054] See Figure 5 and Figure 6 The lower periphery of the first clamping plate 41 and the second clamping plate 51 can be adapted to the second arc-shaped groove 21 so as to prevent the foil of the detection module 60 from extending into the gap between the first clamping plate 41 or the second clamping plate 51 and the second arc-shaped groove 21 when the second clamping plate 51 and the first clamping plate 41 press the detection module 60.

[0055] In some embodiments, the second clamping part 50 includes a second clamping plate 51 and a second sliding part connected to the second clamping plate 51. The second base 20 is formed with a second sliding engagement part along the axial direction. The second sliding part and the second sliding engagement part slide into each other, so that the second clamping part 50 can slide relative to the second base 20 in a direction away from or close to the first clamping part 40.

[0056] The second clamping plate 51 can be circular. Second sliding portions are formed on both sides of the second clamping plate 51 along its width direction; correspondingly, second sliding fit portions are formed on both sides of the second base 20 along its width direction.

[0057] The second sliding part can be a slider 54, and correspondingly, the second sliding engagement part can be a groove 22. By sliding the slider in the groove 22, the second clamping part 50 can slide relative to the second base 20 in a direction away from or close to the first clamping part 40.

[0058] See Figure 6 The second clamping part 50 may include two first plates 52 extending horizontally in opposite directions from both sides of the second clamping plate 51 along the width direction, and two second plates 53 extending vertically from the ends of the two first plates 52, and two sliders 54 extending towards each other from the ends of the two second plates 53.

[0059] See Figure 4 The second base 20 is recessed inward on both sides along its width direction to form a sliding groove 22, which can penetrate the second base 20 along its length direction.

[0060] The assembly method provided in this application embodiment may include steps S1 to S4.

[0061] Step S1: Arrange multiple detection modules 60 at axial intervals.

[0062] Step S2: Provide multiple positioning blocks 70, and place a positioning block 70 between two adjacent detection modules 60 so that each detection module 60 is in its own preset position along the axial direction.

[0063] Step S3: Press the multiple detection modules 60 and multiple positioning blocks 70 along the axial direction to compact the multiple detection modules 60.

[0064] Step S4: Align one side port of catheter 30 with multiple detection modules 60, and push multiple detection modules 60 and multiple positioning blocks 70 into catheter 30 in sequence along the axial direction.

[0065] The assembly method of this application embodiment uses positioning blocks 70 to position each detection module 60, and then compresses each detection module 60 and each positioning block 70 along the axial direction, so that the foil of the detection module 60 is compacted. After the arranged detection modules 60 and positioning blocks 70 are placed into the conduit in sequence, when the axis of the conduit 30 is in the vertical direction, the detection module 60 will not be able to move along the axial direction in the conduit 30, thereby avoiding the detection module 60 from deviating from its corresponding detection position and avoiding damage to the detection module 60.

[0066] In some embodiments, after axially compressing the plurality of detection modules 60 and the plurality of positioning blocks 70, the assembly method further includes: selectively inserting a gasket between two adjacent detection modules 60 so that each of the compacted detection modules 60 can be in its respective preset position along the axial direction; and sequentially pushing the detection modules 60, the plurality of positioning blocks 70 and the gasket into the conduit 30 along the axial direction.

[0067] A zero-point position can be set first, and based on this zero-point position, the positioning block 70 can be used to adjust each detection module 60 to a preset detection position. It is easy to understand that when each detection module 60 and each positioning block 70 are compressed axially, the axial length of the detection module 60 may slightly decrease, causing some detection modules 60 to deviate significantly from their preset detection positions. In such an embodiment, the position of the detection module 60 that is closest to the zero point and significantly deviates from its preset detection position is fine-tuned. For ease of description, the direction axially toward the zero point is called "front," and the direction away from the zero point is called "rear." A shim can be inserted between the detection module 60 and its adjacent front detection module 60. The shim's function is to fine-tune the position of the detection module 60. The shim is thin, much thinner than the axial length of the positioning block 70. In some embodiments, the thickness of the positioning block 70 can be 5cm-10cm, while the thickness of the shim can be 1mm-2mm.

[0068] It is easy to understand that when inserting a shim between two adjacent detection modules 60, since a positioning block 70 is inserted between the two detection modules 60, the shim can be inserted between the positioning block 70 and either of the two detection modules 60.

[0069] In some embodiments, the assembly method further includes: providing a first base 10 and placing the conduit 30 on the first base 10; providing a second base 20, the second base 20 having a scale for calibrating distance along the axial direction; arranging a plurality of detection modules 60 spaced apart along the axial direction on the second base 20; and aligning the first base 10 and the second base 20 after pressing the plurality of detection modules 60 and the plurality of positioning blocks 70 along the axial direction so that one side port of the conduit 30 is aligned with the plurality of detection modules 60.

[0070] In some embodiments, the assembly method further includes: providing a first clamping part 40 and a second clamping part 50; mounting the first clamping part 40 on one axial side of the second base 20; slidably mounting the second clamping part 50 on the other axial side of the second base 20; and pushing the second clamping part 50 toward the direction of the first clamping part 40 to axially compress a plurality of detection modules 60 and a plurality of positioning blocks 70.

[0071] It is easy to understand that the assembly method described above can be completed using the assembly device provided in the embodiments of this application. As mentioned above, the second arc-shaped groove 21 of the assembly device can be used to arrange each detection module 60 and each positioning block 70, the first clamping plate 41 and the second clamping plate 51 can be used to squeeze each detection module 60, and the compacted detection module 60 and positioning block 70 can be pushed into the conduit 30 placed in the first base 10.

[0072] In some embodiments, after axially pressing the plurality of detection modules 60 and the plurality of positioning blocks 70, the assembly method further includes: removing the first clamping part 40 and the second clamping part 50 from the second base 20; providing a booster rod 80, and using the booster rod 80 to push the plurality of detection modules 60 and the plurality of positioning blocks 70 sequentially into the conduit 30 axially.

[0073] In some embodiments, after the plurality of detection modules 60 and the plurality of positioning blocks 70 are sequentially pushed into the conduit 30 along the axial direction, the method further includes: using a booster rod 80 to continue pushing the detection module 60 closest to the second base 20 so that there is a preset distance between the detection module 60 closest to the second base 20 and the port of the conduit 30 facing the second base 20.

[0074] It is easy to understand that after using the booster rod 80 to push all the detection modules 60 and all the positioning blocks 70 into the conduit 30, the distance between the detection module 60 closest to the opening of the conduit 30 and the opening of the conduit 30 can be determined according to the scale of the booster rod 80, so as to leave space for the end to be inserted into the conduit 30 and ensure that the end of the irradiation device is smoothly connected to the conduit 30.

[0075] The assembly method of this application is described in detail below with reference to specific embodiments.

[0076] Align the first base 10 with the second base 20, and install the first clamping part 40 at the zero point position of the second base 20. Arrange the detection modules 60, positioning blocks 70, etc., in the second arc-shaped groove 21 of the second base 20 according to experimental requirements, so that each detection module 60 is in a preset detection position. Push the second clamping part 50 towards the first clamping part 40 to compact the detection modules 60 and positioning blocks 70, etc. Observe the position of the detection modules 60 from the scale of the second base 20, and find the detection modules 60 that are significantly deviated from their corresponding detection positions (for example, the center of the detection module 60 is deviated from the detection position by more than 1 mm). Insert at least one shim into the front side of the detection module 60 to place the detection module 60 in its corresponding detection position. Then, observe the position of the detection modules 60 from the scale of the second base 20 again, find the detection modules 60 that are significantly deviated from their corresponding detection positions, and use shims to make fine adjustments until all detection modules 60 are in their corresponding detection positions. Place the empty conduit 30 on the first base 10, remove the first clamping part 40 and the second clamping part 50, and use the pusher 80 to push the detection module 60, positioning block 70, gasket, etc. into the conduit 30 of the irradiation device in sequence until the distance between the last detection module 60 and the opening of the conduit 30 is a preset distance.

[0077] Regarding the embodiments of the present invention, it should also be noted that, without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other to obtain new embodiments.

[0078] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. The scope of protection of the present invention should be determined by the scope of the claims.
