Description

Technical Field

[0001] The present invention relates to the technical field of nuclear fuel grid cell spring clamping force measuring equipment, and in particular to a nuclear fuel grid cell spring clamping force measuring tool. The present invention also relates to a nuclear fuel grid cell spring clamping force measuring device using the nuclear fuel grid cell spring clamping force measuring tool. Background Art

[0002] The nuclear fuel grid is one of the important components of the nuclear fuel assembly and is also the component with a relatively complex structure in the nuclear fuel assembly.

[0003] Specifically, the main frame structure of the nuclear fuel grid is arranged with multiple grid cells in an array. Each grid cell is a cavity structure with a square cross-section. On the inner wall of the grid, at least one set of rigid convexities and springs are symmetrically arranged. The rigid convexities are rigid protrusions that provide relatively reliable lateral support. When assembling a nuclear fuel assembly, a fuel rod is inserted into each grid cell. After the fuel rod is inserted into the grid cell, it is located between the rigid convexity and spring inside the grid cell. The rigid convexity and spring on the inner wall of the grid cell are located on either side of the fuel rod. At this time, the spring is subjected to the lateral squeeze of the fuel rod and forms a moderate compression. The spring's stretching and rebounding force exerts a lateral squeezing force on the fuel rod, pressing the fuel rod toward the side of the rigid convexity. In this way, the spring and rigid convexity located on both sides of the fuel rod cooperate to reliably clamp the fuel rod between the spring and rigid convexity, ensuring a stable assembly between the fuel rod and the grid cell.

[0004] During the actual assembly operation of the above-mentioned fuel rod and grid element, if the fitting clamping force between the spring and the rigid convex is insufficient, the assembly stability between the fuel rod and the grid element will be reduced, thereby causing the fuel rod inserted in the grid element to loosen or be misplaced, affecting the overall assembly reliability of the nuclear fuel assembly; if the fitting clamping force between the spring and the rigid convex is too large, it will have an adverse effect on the main structure of the fuel rod, and it is easy to cause the fuel rod to be damaged due to excessive pressure, which will also have an adverse effect on the overall assembly of the nuclear fuel assembly.

[0005] Therefore, it is necessary to measure the clamping force formed by the spring and the rigid convex in the grid cell, so as to adjust the clamping force in time according to the measurement structure, thereby ensuring that the clamping force inside the grid cell can match the stable assembly requirements of the fuel rod and ensure the stable assembly of the nuclear fuel assembly. However, there are currently no professional tools in the industry that can accurately measure the clamping force of the spring inside the above-mentioned grid cell. If conventional pressure measurement tools in related industries are used, they are limited by the structural characteristics of the grid cell itself, and the existing pressure measurement tools cannot be fully adapted to the existing structure of the grid cell, resulting in poor accuracy of the spring clamping force data inside the grid cell measured by conventional pressure measurement tools. In actual operation, due to the cross-adaptability of existing tools and the grid cell structure, the actual measurement operation efficiency is low, which restricts the overall efficiency of the assembly of nuclear fuel assemblies and related operations.

[0006] In view of this, how to provide a tool to achieve accurate and efficient measurement of the spring clamping force in the gate element is an important technical problem that technical personnel in this field currently need to solve. Summary of the Invention

[0029] The core of the present invention is to provide a nuclear fuel grid cell spring clamping force measurement tool, which can accurately and efficiently measure the spring clamping force in the nuclear fuel grid cell; the present invention also provides a nuclear fuel grid cell spring clamping force measurement device using the above-mentioned nuclear fuel grid cell spring clamping force measurement tool.

[0030] In order to enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0031] Please refer to Figures 1 to 3 .

[0032] In a specific embodiment, the nuclear fuel grid cell spring clamping force measuring tool provided by the present invention includes a guide rod 11 and a base 12. The assembly end of the guide rod 11 is linked to the base 12, and the free end of the guide rod 11 can be inserted into the grid cell of the nuclear fuel grid. The free end of the guide rod 11 is provided with a pressure sensor 13, and the pressure-sensitive trigger end 131 of the pressure sensor 13 protrudes from the outer peripheral wall of the guide rod 11.

[0033] During specific operation, when it is necessary to measure the spring clamping force inside the grid element on the nuclear fuel grid, the external drive control device can be linked to the base 12, or the staff can hold the base 12 to achieve overall linkage control of the nuclear fuel grid element spring clamping force measuring tool. After that, the free end of the guide rod 11 can be manipulated to be inserted into the target grid element for spring clamping force measurement. After the free end of the guide rod 11 is inserted into the grid element to be measured and installed in place, the spring in the grid element is aligned with the rigid convex to apply radial pressure to the free end of the guide rod 11. At this time, the pressure-sensitive trigger end 131 of the pressure sensor 13 is pressurized and triggered to sense, so as to measure the pressure it is subjected to. The result obtained by the measurement is the clamping force value of the spring in the grid element into which the current guide rod 11 is inserted.

[0034] After the spring clamping force of the above-mentioned gate element is measured, the base 12 is controlled to move to drive the guide rod 11 to be synchronously pulled out of the gate element, and the next gate element can be aligned and inserted and the spring clamping force can be measured.

[0035] The nuclear fuel grid cell spring clamping force measuring tool integrates a pressure sensor 13 on a guide rod 11 and utilizes the aligned insertion of the guide rod 11 to achieve full structural adaptation with the measured cell. Since the pressure-sensitive trigger end 131 of the pressure sensor 13 is arranged on the outer periphery of the guide rod 11, the pressure sensor 13 can be fully pressurized to accurately and quickly measure the corresponding spring clamping force value, thereby greatly improving the measurement efficiency of the spring clamping force in the nuclear fuel grid cell. The measurement results are accurate and reliable, fully meeting the assembly requirements of the corresponding nuclear fuel assembly.

[0036] It should be noted that the pressure sensor 13 used in this solution only needs to be a conventional pressure sensor 13 in the industry according to the working conditions. It is not difficult to understand that the pressure-sensitive trigger end 131 of the pressure sensor 13 selected here can be an action component that can reciprocate and retract along the radial direction of the guide rod 11, or can be a component that can be appropriately tilted and reset to achieve pressure measurement and switching between non-working states, or can be a fixed structure that appropriately protrudes from the side wall of the guide rod 11. In actual applications, staff can flexibly select the specific type of pressure sensor 13 used in this solution based on specific working conditions and measurement requirements. In principle, any type of pressure sensor 13 can be used as long as it can meet the actual application needs of the nuclear fuel grid element spring clamping force measurement tool.

[0037] Specifically, the base 12 includes a support portion 121 and a positioning portion 122. The positioning portion 122 has a positioning cavity 123 inside. The assembly end of the guide rod 11 is inserted into the positioning cavity 123, and the free end of the guide rod 11 extends out of the positioning cavity 123 from the end of the support portion 121 away from the positioning portion 122. The positioning cavity 123 can provide sufficient assembly space for the assembly end of the guide rod 11. Combined with the main structure of the support portion 121 and the positioning portion 122, it can provide reliable structural support for the guide rod 11 connected to the base 12, thereby ensuring the assembly strength and linkage effect between the guide rod 11 and the base 12. As a result, the operation of inserting or removing the guide rod 11 into or out of the target grid element through the base 12 is smoother and more efficient, with higher operating accuracy, and the corresponding pressure sensor 13 is more accurate and efficient in measuring the spring clamping force.

[0038] Generally, it is preferable for the positioning cavity 123 to adopt a semi-enclosed cavity structure with a side opening as shown in the figure, so as to provide more sufficient operating space when assembling the guide rod 11 and the base 12, and to reduce the difficulty of subsequent assembly inspection and maintenance. Of course, a fully enclosed cavity structure can also be selected as the actual structure of the positioning cavity 123 to ensure that the positioning cavity 123 can provide more sufficient structural protection for the assembly end of the guide rod 11.

[0039] More specifically, a transfer positioning member 124 is disposed within the positioning cavity 123 and is detachably connected to the assembly end of the guide rod 11. This detachable connection facilitates removal of the guide rod 11 from the base 12 when necessary, allowing for component inspection, maintenance, or replacement, ensuring the actual operating requirements of the nuclear fuel grid cell spring clamping force measurement tool.

[0040] Typically, the adapter locator 124 is threadedly connected to the assembly end of the guide rod 11. In practical applications, a sleeve with an internal thread can be used as the adapter locator 124, and the outer wall of the assembly end of the guide rod 11 needs to have an external thread structure that can adapt to the internal thread of the sleeve. Alternatively, a screw with an external thread can be used as the adapter locator 124, and the assembly end of the guide rod 11 needs to have an axially recessed screw hole to allow for a threaded connection with the screw.

[0041] Of course, the adaptation method between the adapter positioning member 124 and the assembly end of the guide rod 11 is not limited to the threaded adaptation described above. Other assembly structures such as snap-on adaptation that can achieve reliable linkage assembly and convenient disassembly can also be selected. In principle, as long as it can meet the actual working conditions of the nuclear fuel grid element spring clamping force measuring tool, it can be used.

[0042] On the other hand, the width of the support portion 121 is greater than the width of the positioning portion 122, so as to form a stepped surface 125 at the junction of the support portion 121 and the positioning portion 122. The larger width of the support portion 121 can provide more reliable structural support for the positioning portion 122 and the guide rod 11. Combined with the stepped surface 125 structure formed by the width difference between the support portion 121 and the positioning portion 122, it can further optimize the stress distribution between the support portion 121 and the positioning portion 122, improve the overall structural rigidity of the base 12, and make the overall assembly structure of the nuclear fuel grid element spring clamping force measurement tool more solid and reliable.

[0043] It is not difficult to understand that the support portion 121 and the positioning portion 122 are usually structural parts with a square cross-sectional outer contour, and structural parts with a circular cross-section or other shapes can also be selected. The staff can choose and adjust accordingly based on the specific working conditions and processing difficulty.

[0044] In addition, a detection groove 111 is formed radially along the outer periphery of the free end of the guide rod 11. The pressure sensor 13 is embedded in the detection groove 111, and the pressure-sensitive trigger end 131 of the pressure sensor 13 extends from the inside out of the notch of the detection groove 111. The detection groove 111 provides ample assembly space and reliable structural protection for the pressure sensor 13, preventing bumps or scratches on the pressure sensor 13 during insertion and removal of the guide rod 11 from the gate element, thereby ensuring the measurement accuracy and service life of the pressure sensor 13.

[0045] In a specific embodiment, the nuclear fuel grid cell spring clamping force measuring device provided by the present invention includes a nuclear fuel grid cell spring clamping force measuring tool and a drive control device capable of driving the nuclear fuel grid cell spring clamping force measuring tool to move. The nuclear fuel grid cell spring clamping force measuring tool is the nuclear fuel grid cell spring clamping force measuring tool described above. The nuclear fuel grid cell spring clamping force measuring device uses the drive control device to drive the nuclear fuel grid cell spring clamping force measuring device to measure the spring clamping force of multiple cells arranged in an array on the grid one by one. This device can quickly perform batch processing of the cells, significantly improving the efficiency of spring clamping force processing of multiple cells, and has high measurement accuracy, with accurate and reliable measurement results.

[0046] Furthermore, the driving control device is a robotic arm device, which has high movement efficiency and good adaptability to working conditions. It can drive the nuclear fuel grid element spring clamping force measurement tool to move synchronously with the cooperation of a computer and other supporting control devices, thereby achieving station matching of multiple elements, thereby further improving the batch measurement processing efficiency of the spring clamping forces of the corresponding multiple elements.

[0047] In addition, the robotic arm device has a linkage mounting groove, the support part 121 is aligned and embedded in the linkage mounting groove, and the stepped surface 125 fits snugly with the inner wall of the groove of the linkage mounting groove, so as to further improve the assembly strength and linkage effect between the nuclear fuel grid element spring clamping force measurement tool and the robotic arm device.

[0048] Correspondingly, a linkage screw hole is provided at the bottom of the linkage mounting slot, and an auxiliary mounting member 126 is provided at one end of the support portion 121 away from the positioning portion 122. The auxiliary mounting member 126 is a linkage stud protruding from the outer wall of the support portion 121 and threadedly connected to the linkage screw hole. Through the aligned insertion and threaded connection between the linkage stud and the linkage screw hole, a reliable connection is achieved between the support portion 121 of the base 12 and the linkage mounting slot, thereby further improving the assembly strength and linkage effect between the nuclear fuel grid cell spring clamping force measurement tool and the robotic arm device, thereby making the operation process of the nuclear fuel grid cell spring clamping force measurement device smoother and more efficient.

[0049] Of course, the auxiliary mounting part 126 may also be a structural part such as a locking pin, a hook or a dovetail groove that can realize a linkage connection. In actual application, it can be flexibly selected and adjusted according to the specific working conditions and equipment layout requirements. Accordingly, the auxiliary connection adaptation method between the base 12 support part 121 and the linkage mounting groove is also adjusted to a snap connection or other adaptation form. In principle, as long as the linkage connection between the base 12 and the operating end of the robotic arm device can be guaranteed to meet the operational requirements of the nuclear fuel grid element spring clamping force measurement operation, it can be used.

[0050] In summary, the nuclear fuel grid cell spring clamping force measuring tool provided in the present invention, during its operation and use, when it is necessary to measure the spring clamping force inside the grid cell on the nuclear fuel grid, the external drive control device can be linked to the base, or the base can be held by a staff member to achieve the overall linkage control of the nuclear fuel grid cell spring clamping force measuring tool, and then the free end of the guide rod can be manipulated to be inserted into the target grid cell for which the spring clamping force measurement is required, and after the free end of the guide rod is inserted into the measured grid cell and inserted into place, the spring in the grid cell is aligned with the rigid convex to apply radial pressure to the free end of the guide rod, and at this time the pressure-sensitive trigger end of the pressure sensor is pressurized and triggered to sense, so as to measure the pressure it is subjected to, and the result obtained by the measurement is the clamping force value of the spring in the grid cell into which the current guide rod is inserted. After the spring clamping force of the above-mentioned grid cell is measured, the base is controlled to move to drive the guide rod to be synchronously pulled out of the grid cell, so that the next grid cell can be aligned and inserted and the spring clamping force can be measured. The nuclear fuel grid cell spring clamping force measurement tool integrates a pressure sensor on a guide rod and utilizes the aligned insertion of the guide rod to achieve full structural adaptation with the measured cell. Since the pressure-sensitive trigger end of the pressure sensor is arranged on the outer periphery of the guide rod, the pressure sensor can be fully pressurized to accurately and quickly measure the corresponding spring clamping force value, thereby significantly improving the measurement efficiency of the spring clamping force in the nuclear fuel grid cell. The measurement results are accurate and reliable, fully meeting the assembly requirements of the corresponding nuclear fuel assembly.

[0051] The present invention also provides a nuclear fuel grid cell spring clamping force measuring device, which uses a driving control device to drive the nuclear fuel grid cell spring clamping force measurement to measure the spring clamping force of multiple grid cells arranged in an array on the grid one by one. It can quickly implement batch processing of grid cells, greatly improve the spring clamping force processing efficiency of multiple grid cells, and its measurement accuracy is high, and the measurement results are accurate and reliable.
