Description

Technical Field

[0001] This utility model relates to the field of radiation resistance testing in nuclear power plants, and in particular to a radiation resistance testing device for nuclear power plants. Background Technology

[0002] With the booming development of the nuclear power industry, more and more intelligent equipment such as robots are entering nuclear power plants. Given the radiation dose present in some areas of nuclear power plants, robots need to possess a certain level of radiation resistance. Before leaving the factory, robots need to undergo radiation testing to assess their radiation resistance. However, traditional methods for arranging radiation resistance testing equipment are rather crude, simply placing the robot equipment and related components directly on the ground or against a wall for testing. This approach is difficult to standardize, resulting in low space utilization efficiency, chaotic power-on debugging circuits, inaccurate radiation dose measurements, and a lack of capacity for long-term, large-scale testing, making it difficult to meet the growing radiation resistance testing needs of intelligent nuclear power equipment.

[0027] Please see Figures 1 to 5This invention relates to a radiation resistance testing device for nuclear power plants, as described in some embodiments. The device includes at least one radiation resistance testing stand, each of which comprises a base 1, a longitudinal movement assembly 2, a transverse movement assembly 3, a mounting assembly 4, and a measuring assembly 5. The longitudinal movement assembly 2 is mounted on the bottom of the base 1, and the transverse movement assembly 3 is mounted on the side wall of the base 1. When the base 1 is in a longitudinal position, the longitudinal movement assembly 2 moves the base 1; when the base 1 is in a transverse position, the transverse movement assembly 3 moves the base 1. The mounting assembly 4 is movably connected to the base 1 and can move along the longitudinal direction of the base 1. The measuring assembly 5 is detachably mounted on the mounting assembly 4 and used to measure the test specimen.

[0028] In this embodiment, the nuclear power plant radiation resistance testing device includes two radiation resistance test stands arranged in a mirror image. The two stands can be used separately or assembled. When used individually, they can adapt to narrow spaces and pass through narrow irradiation hall doors. When assembled, the two radiation resistance test stands offer a larger usable area and load-bearing capacity. The base 1 is a cabinet, and a longitudinal moving component 2 is installed in the longitudinal direction of the radiation resistance test stands, while a transverse moving component 3 is installed in the transverse direction, allowing for convenient use of the base 1 in either a longitudinal or transverse configuration.

[0029] Understandably, the nuclear power plant radiation tolerance testing device, by setting up a longitudinal movement component 2 and a transverse movement component 3, facilitates the use and movement of the substrate 1 in either a longitudinal or transverse state. Simultaneously, the installation component 4, which is movably connected to the substrate 1 and can move along the longitudinal direction of the substrate 1, improves the utilization rate of longitudinal space. Furthermore, the measuring component 5 is detachably mounted on the installation component 4, making it convenient to install and replace, thus improving work efficiency.

[0030] like Figure 1 and Figure 2 As shown, the base 1 is provided with a guide rail 11. The mounting assembly 4 includes a slider 41 movably connected to the guide rail 11, a positioning frame 42 connected to the slider 41, and a mounting plate 43 mounted on the positioning frame 42. The positioning frame 42 is a frame component, while the mounting plate 43 is a perforated mesh panel. The measuring assembly 5 can be detachably connected to the perforated mesh panel via bolts, clips, hooks, or other connectors. In some other embodiments, the perforated mesh panel can be replaced with a regular panel with holes. More specifically, there are two mounting plates 43, arranged separately along the longitudinal direction of the base 1, i.e., the two mounting plates 43 are positioned vertically. The mounting plates 43 can be raised and lowered by moving the slider 41 along the guide rail 11. The adjustment range of the mounting plates 43 is 50cm, improving the adaptability of the measuring assembly 5 in longitudinal space.

[0031] The longitudinal movement component 2 includes a plurality of first universal wheels 21 connected to the bottom of the base 1, and the lateral movement component 3 includes a plurality of second universal wheels 31 connected to the side wall of the base 1. The arrangement of the first universal wheels 21 and the second universal wheels 31 makes it convenient to use whether the base 1 is in a longitudinal or lateral state.

[0032] The nuclear power plant radiation tolerance testing apparatus also includes an image acquisition component 6, which includes an image acquisition connector 61 connected to the side wall of the substrate 1 and an image acquisition device (not shown) mounted on the image acquisition connector 61. The image acquisition device is specifically distributed on two side walls of the substrate 1, and the image acquisition device observes and records the appearance changes of the test piece in real time during the test.

[0033] like Figure 2 and Figure 3 As shown, the nuclear power plant radiation tolerance testing device also includes an electrical cabinet assembly 7 installed inside the base 1. The electrical cabinet assembly 7 includes a shielding chamber 71, an electrical quick-connect connector 72, and a terminal block 73. Specifically, the shielding chamber 71 can be installed in the lower part of the base 1, housing necessary electrical equipment such as power supplies. The electrical quick-connect connector 72 can be installed in the lower part of the base 1, accommodating various electrical connectors for convenient wiring and debugging. The cables of the measuring component 5 can be converted to a unified interface through the electrical quick-connect connector 72, facilitating unified debugging and testing, and solving the problem of inconsistent interfaces hindering large-scale standardized testing. The terminal block 73 can be installed in the middle of the base 1, and can be fixed to the base 1 via a slide rail. The cables of the measuring component 5 can pass directly through the front of the mounting plate 43, routed through cable trays to the shielding chamber 71 and the electrical quick-connect connector 72, and then connected to the outside, thus organizing the internal cables in one place and solving the problem of messy debugging wiring.

[0034] like Figure 4 and Figure 5 As shown, the measurement assembly 5 includes a mounting platform 51 connected to the mounting plate 43 and a measuring tool mounted on the mounting platform 51. The measuring tool can be a test device or a dosimeter. The mounting platform 51 can be detachably connected to the mounting plate 43 via bolts, clips, hanging components, or other connectors. The mounting platform 51 can carry test equipment to receive irradiation for testing, or it can carry multiple dosimeters to verify the dose received during the irradiation experiment. Figure 4 The structure of the mounting platform 51 is as follows when the measuring tool is a test device. Figure 5The measurement tool is a dosimeter mounting platform 51. This test equipment can be a chip-level, board-level, or component-level device under test. In a specific embodiment, due to the standardized relative positions of the grid on the mounting plate 43, multiple dosimeters can be arranged simultaneously around the device under test, for example, using a 5×5 matrix arrangement. By placing the device under test at a certain position and repeating experiments, the radiation dose at the device under test can be calculated more accurately.

[0035] Furthermore, the measuring component 5 includes an extension telescopic rod 52, with its two ends connected to the mounting plate 43 and the mounting platform 51, respectively. In some irradiation halls, the base of the irradiation source is obstructed during operation. When high dose rate tests are required, the irradiated equipment needs to be closer to the irradiation source, but the irradiation test platform is blocked by the base and cannot get closer. Using the extension telescopic rod 52 allows the measuring tool to be closer to the irradiation source, enabling tests under high dose rate conditions and improving the utilization rate of the high-dose area within the irradiation hall. Specifically, the extension telescopic rod 52 has a telescopic range of 15cm, with a minimum length of 55cm and a maximum length of 70cm.

[0036] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model. Therefore, all equivalent transformations and modifications made within the scope of the claims of the present utility model should fall within the coverage of the claims of the present utility model.
