Abstract
Description
Technical Field
[0001] This utility model relates to the field of radiation protection device technology, specifically to an XRF spectral scanning radiation protection device. Background Technology
[0002] Characterization of rocks and minerals is fundamental to geological and geoscience research, and X-ray fluorescence spectroscopy (XRF) is an analytical technique used to determine the composition of rock and mineral samples. Researchers use XRF to quantitatively and qualitatively determine the abundance of major and trace elements to characterize and understand rock geochemistry.
[0003] In existing technologies, when testing materials such as rock cores, specimens, and soil samples, it is necessary to use a handheld XRF analyzer to test each sample individually, which is inefficient and poses a certain radiation hazard to the analysis and testing personnel. Utility Model Content
[0004] To address the technical problem of significant radiation damage to the human body when X-ray fluorescence spectroscopy (XRF) is used to detect samples, this utility model provides an XRF spectral scanning radiation protection device, including an adjustment hole, a first fixing plate, a top cover plate, an instrument operation window, a second fixing plate, a movable adjustment plate, protective lead glass, an instrument support, a sample stage, a third fixing plate, a linear guide rail, a slider, connecting fasteners, and a limiting block, as well as a limiting set screw;
[0005] The first fixing plate, the second fixing plate, and the third fixing plate are all fixedly installed on the instrument bracket through adjustment holes;
[0006] A slider and a limit block are installed on the linear guide rail, with the slider positioned above the limit block;
[0007] The limiting block is equipped with a limiting screw, and the limiting block can be fixed on the linear guide rail by locking the limiting screw, thereby preventing the slider on the linear guide rail from sliding down.
[0008] The linear guide rail is mounted on the instrument bracket;
[0009] The movable adjustment plate is mounted on the slider of the linear guide rail via a connecting fastener, and the movable adjustment plate can be adjusted up and down by the slider of the linear guide rail.
[0010] The upper cover plate is installed on the top surface of the instrument bracket.
[0011] The instrument operation window is mounted on the instrument bracket, located on the right side of the first fixing plate and the left side of the second fixing plate.
[0012] The protective lead glass is fixedly installed on the front side of the instrument bracket using glass glue.
[0013] The sample stage is a movable support platform.
[0014] The first fixing plate, the second fixing plate, the third fixing plate, the movable adjustment plate, the top cover plate, and the inner side of the instrument operation window are all covered with radiation-proof lead sheeting.
[0015] The side facing the instrument bracket is the inner side, and the opposite side is the outer side.
[0016] The movable adjustment plate is located outside the first fixed plate, the second fixed plate, and the third fixed plate.
[0017] The adjustment hole is a groove hole, used for adjustment during the installation of the first fixing plate.
[0018] The X-ray fluorescence spectrometer (XRF) instrument is mounted on the inside of the top cover.
[0019] The instrument's operating window is a small door that can be opened and is located near the X-ray fluorescence spectroscopy component.
[0020] Beneficial Effects: This invention primarily addresses the radioactivity of X-ray fluorescence spectroscopy (XRF) components with a protective structure. After the geological sample to be scanned is placed on the sample stage, the positions of the radiation-shielding movable adjustment plates on both sides are adjusted vertically until their lower edges are fixed at a point where they do not interfere with the upper surface of the core sample. These adjustment plates effectively block X-rays emitted during XRF testing. A lead glass observation window allows for safe real-time monitoring of the scanning process. This solves the technical problem of significant X-ray radiation exposure to the human body during geological sample testing. A radiation-shielding instrument operation window is designed on the side of the instrument stand, located near the XRF component. Opening this window allows for quick adjustment of the installed XRF component, facilitating testing and improving work efficiency. Attached Figure Description

Detailed Implementation
[0029] like Figure 1 As shown, this utility model embodiment provides an XRF spectral scanning radiation protection device. The device mainly has a protective structure against the radioactivity of X-ray fluorescence spectral components, including an adjustment hole 1, a first fixing plate 2, an upper cover plate 3, an instrument operation window 4, a second fixing plate 5, a movable adjustment plate 7, a protective lead glass 8, an instrument support 9, a sample stage 10, a third fixing plate 11, a linear guide rail 12, a slider 13, a connecting fixing component 14, a limiting block 15, and a limiting set screw 16.
[0030] The first fixing plate 2, the second fixing plate 5 and the third fixing plate 11 are all fixedly installed on the instrument bracket 9 through the adjustment hole 1;
[0031] The linear guide rail 12 is equipped with a slider 13 and a limiting block 15, with the slider 13 above the limiting block 15;
[0032] The limiting block 15 is equipped with a limiting screw 16. The limiting block 15 can be fixed on the linear guide rail 12 by locking the limiting screw 16, thereby preventing the slider 13 on the linear guide rail 12 from sliding down.
[0033] The linear guide rail 12 is mounted on the instrument bracket 9;
[0034] The movable adjustment plate 7 is mounted on the slider 13 of the linear guide rail 12 via the connecting fastener 14, and the movable adjustment plate 7 can be adjusted up and down by the slider 13 of the linear guide rail 12.
[0035] The upper cover plate 3 is installed on the top surface of the instrument bracket 9.
[0036] The instrument operation window 4 is mounted on the instrument bracket 9, located on the right side of the first fixing plate 2 and the left side of the second fixing plate 5.
[0037] The protective lead glass 8 is fixedly installed on the front side of the instrument bracket 9 with glass glue.
[0038] The sample stage 10 is a movable support platform.
[0039] The first fixing plate 2, the second fixing plate 5, the third fixing plate 11, the movable adjustment plate 7, the upper cover plate 3, and the inner side of the instrument operation window 4 are all covered with radiation-proof lead sheeting.
[0040] The movable adjustment plate 7 is located outside the first fixed plate 2, the second fixed plate 5, and the third fixed plate 11, and will not interfere with the vertical adjustment.
[0041] The adjustment hole 1 is a groove hole, used for adjustment during the installation of the first fixing plate 2.

[0043] The instrument operation window 4 is a small door that can be opened and is located near the X-ray fluorescence spectroscopy component.
[0044] When the device is in operation, first adjust the movable adjustment plate 7 upwards to reach the uppermost end of the guide rail, then use the limiting block 15 to abut against the slider 13 on the linear guide rail 12, and then lock the limiting screw 16 to fix the movable adjustment plate 7 on the linear guide rail 12 so that it does not slip. Place the geological sample 6 to be tested on the sample stage 10, move the sample stage 10 with the sample placed on it to the working position below the instrument support 9, then open the limiting screw 16 so that the limiting block 14 no longer abuts against the slider 13, and adjust the height of the movable adjustment plate 7 downwards so that the lower edge of the movable adjustment plate 7 is... After reaching the point on the upper surface of the core sample 6 where no interference occurs, use the limiting block 14 to hold the slider 13 on the linear guide rail 12 and then lock the limiting screw 16 to fix the moving adjustment plate 7 on the linear guide rail 12 so that it does not slip. At this time, the moving adjustment plate 7 effectively blocks the X-rays that overflow during the X-ray fluorescence spectroscopy component test. Open the instrument operation window 4, turn on the X-ray fluorescence spectroscopy (XRF) instrument, and then close the instrument operation window 4.

After the test is completed, open the small door of the instrument operation window 4, turn off the instrument, and then close the instrument operation window 4. Adjust the moving adjustment plate 7 upward and use the limiting block 14 to hold the slider on the linear guide rail 12 to fix it so that the moving adjustment plate 7 is fixed on the linear guide rail 12 so that it does not slip. Remove the sample stage 10, and the test is over.
