Description

Technical Field

[0001] This utility model relates to the field of vertical high-frequency electromagnetic oscillation technology for radioactive samples, specifically to a vertical high-frequency electromagnetic oscillator for radioactive samples. Background Technology

[0002] In both emergency and routine environmental pollution monitoring, total radioactivity measurement is the primary means of preliminary assessment for the presence of radioactive contamination and for sample classification. In the event of a nuclear accident emergency, total radioactivity measurement data can be used to estimate the type of nuclide in the sample. Measuring the α / β activity ratio in the sample serves as a supplementary criterion for event identification in environmental radioactivity monitoring. Common interfering factors affecting the accuracy of total α and total β radioactivity detection include: the composition of the sample's radiation type, the absorbing material between the particle energy source and the detector, the sample's hygroscopicity, the uniformity of sample ash, and the uniformity of sample preparation. As a crucial part of the measurement process, sample preparation has a significant impact on the entire experimental procedure and the accuracy of the data.

[0003] Currently, most sample preparation tools include straight needles or pressure plates. The working principle of pressure plates is basically to press the sample against a plate with a uniform inner diameter in the sample tray. This can easily cause the sample to stick to the plate, resulting in reduced measurement results. Straight needles are difficult to ensure uniform sample thickness. The disadvantages of existing technologies are that the sample is not uniform and flat enough, and the sample preparation efficiency is low. At present, experimenters mainly rely on straight needles for sample preparation, which is time-consuming and occupies most of the time in the entire experimental process. This makes it difficult to achieve rapid and accurate measurements in emergency situations and for large-scale sample measurements, resulting in uneven sample density and inconsistent sample thickness. This can easily lead to problems such as the self-absorption of alpha radioactivity, causing deviations in experimental data. Utility Model Content

[0004] To solve the above-mentioned technical problems, a high-frequency electromagnetic oscillator for vertical radioactive samples is provided. This technical solution solves the problems of uneven and rough sample spreading and low spreading efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-frequency electromagnetic oscillator for radioactive samples includes a housing. A vertical vibration controller is installed on the bottom inner side of the housing. A high-frequency electromagnetic oscillator is installed on the upper end of the vertical vibration controller. A clamping assembly is installed on the upper end of the high-frequency electromagnetic oscillator. The clamping assembly includes a mounting shell. A top plate is fixedly connected to the upper end of the mounting shell. Four sets of clamping blocks are slidably connected to the upper end of the top plate. A placement plate is provided on the upper end of the top plate. A pre-laying mechanism is installed on the upper end of the housing. The pre-laying mechanism includes a low-speed motor and a laying rod. The laying rod is fixedly connected to the output end of the low-speed motor.

[0007] Preferably, the pre-laying sample mechanism further includes a mounting frame, which is fixedly connected to the upper end of the housing. A first electric push rod is fixedly connected to the upper end of the mounting frame. The output end of the first electric push rod extends to the inner side of the mounting frame and is fixedly connected to a mounting frame. The low-speed motor is fixedly installed on the inner side of the mounting frame.

[0008] Preferably, the upper end of the top plate is provided with four sets of sliding grooves, and the lower ends of the four sets of clamping blocks are all fixedly connected with sliding rods, which are slidably connected inside the sliding grooves.

[0009] Preferably, a drive disk is rotatably connected to the inner side of the mounting shell, and a drive groove adapted to the slide rod is opened through the upper end of the drive disk. The drive groove is slidably connected to the slide rod, and one end of the slide rod extends to the lower end of the drive groove and is fixedly connected to a limit plate.

[0010] Preferably, a rotating shaft is fixedly connected to the lower end of the drive disk, and a driven gear is fixedly connected to the lower end of the rotating shaft.

[0011] Preferably, the clamping assembly further includes a second electric push rod, which is fixedly installed on the outside of the mounting housing. The output end of the second electric push rod extends to the inside of the mounting housing and is fixedly connected to a toothed plate, which meshes with a driven gear.

[0012] Preferably, the outer side of the outer casing has several sets of heat dissipation holes.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: by generating vertical vibration through a vertical vibration controller, combined with the high-frequency electromagnetic field generated by a high-frequency electromagnetic oscillator, the mixing and homogenization of radioactive samples in the container can be effectively promoted. This dual mechanism ensures the reliability and accuracy of radioactive samples in subsequent analysis, providing a solid foundation for scientific research or experimental analysis.

[0014] By setting up a pre-laying mechanism, a low-speed motor drives the laying rod to rotate, realizing the pre-laying operation of the sample. This reduces the overall time required for uniformly laying the sample, improves the efficiency of sample laying, and provides better conditions for subsequent vibration and electromagnetic oscillation treatment.

[0015] By setting up a clamping component, four sets of clamping blocks slide simultaneously toward the center of the top plate, achieving stable clamping of the placement tray. This not only improves the stability of the placement tray but also ensures the uniformity of sample spreading. Furthermore, it allows for quick locking and unlocking of the placement tray, facilitating rapid removal after uniform spreading for the next set of samples, thereby improving work efficiency.

[0026] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0027] Example 1

[0028] Please refer to Figures 1-5 As shown, a radioactive sample vertical high-frequency electromagnetic oscillator includes a housing 1. A vertical vibration controller 101 is installed on the bottom inner side of the housing 1. A high-frequency electromagnetic oscillator 102 is installed on the upper end of the vertical vibration controller 101. A clamping assembly 3 is installed on the upper end of the high-frequency electromagnetic oscillator 102. The clamping assembly 3 includes a mounting shell 301. A top plate 302 is fixedly connected to the upper end of the mounting shell 301. Four sets of clamping blocks 304 are slidably connected to the upper end of the top plate 302. A placement plate 4 is provided on the upper end of the top plate 302. A pre-laying mechanism 2 is installed on the upper end of the housing 1. The pre-laying mechanism 2 includes a low-speed motor 204 and a laying rod 205. The laying rod 205 is fixedly connected to the output end of the low-speed motor 204.

[0029] In this scheme, the vertical vibration controller 101 can effectively promote the mixing and homogenization of radioactive samples in the container by generating vertical vibration, thereby ensuring the reliability of the analysis results.

[0030] The high-frequency electromagnetic oscillator 102 is the core component of the vertical high-frequency electromagnetic oscillator for radioactive samples. It is responsible for generating a high-frequency electromagnetic field, which can act on the radioactive sample to cause the atoms or molecules inside to vibrate, rotate, or move.

[0031] Furthermore, the placement tray 4 is used to place samples. The four sets of clamping blocks 304 can slide simultaneously toward the center of the top plate 302 to clamp and fix the placement tray 4, thereby improving the stability of the placement tray 4 and increasing the uniformity of sample spreading. It is quick and convenient to lock and unlock the placement tray 4 quickly, and it is easy to take it out after uniform spreading, so as to spread the sample on the next set of placement trays 4.

[0032] Furthermore, after the sample is placed in the placement tray 4, the low-speed motor 204 can drive the sample spreading rod 205 to rotate, thereby pre-spreading the sample inside the placement tray 4, reducing the sample spreading time and improving the sample spreading efficiency.

[0033] Example 2

[0034] Please refer to Figure 2 As shown, the pre-laying mechanism 2 also includes a mounting frame 201, which is fixedly connected to the upper end of the housing 1. A first electric push rod 203 is fixedly connected to the upper end of the mounting frame 201. The output end of the first electric push rod 203 extends to the inner side of the mounting frame 201 and is fixedly connected to a mounting frame 202. A low-speed motor 204 is fixedly installed on the inner side of the mounting frame 202.

[0035] In this scheme, the first electric push rod 203 can drive the mounting frame 202 to move downward, thereby driving the low-speed motor 204 and the sample spreading rod 205 to move downward, so that the sample spreading rod 205 moves into the interior of the placement tray 4, thereby rotating to perform a pre-flattening operation on the sample, thereby reducing the overall time required for uniformly flattening the sample.

[0036] Example 3

[0037] Please refer to Figures 4-5 As shown, four sets of sliding grooves 305 are provided through the upper end of the top plate 302, and sliding rods 306 are fixedly connected to the lower ends of the four sets of clamping blocks 304. The sliding rods 306 are slidably connected to the inside of the sliding grooves 305.

[0038] A drive disk 303 is rotatably connected to the inner side of the mounting housing 301. A drive groove 307 adapted to the slide rod 306 is opened through the upper end of the drive disk 303. The drive groove 307 is slidably connected to the slide rod 306. One end of the slide rod 306 extends to the lower end of the drive groove 307 and is fixedly connected to a limit plate 308.

[0039] A rotating shaft 309 is fixedly connected to the lower end of the drive disk 303, and a driven gear 310 is fixedly connected to the lower end of the rotating shaft 309.

[0040] The clamping assembly 3 also includes a second electric push rod 312, which is fixedly installed on the outside of the mounting housing 301. The output end of the second electric push rod 312 extends to the inside of the mounting housing 301 and is fixedly connected to a toothed plate 311, which meshes with the driven gear 310.

[0041] In this scheme, the second electric push rod 312 is electrically connected to an external power supply. The second electric push rod 312 can drive the toothed plate 311 to move, thereby driving the driven gear 310 to rotate the shaft 309, which in turn drives the drive disk 303 to rotate. Through the drive groove 307, the slide rod 306 slides inside the slide groove 305, thereby driving multiple sets of clamping blocks 304 to clamp the placement disk 4.

[0042] Several sets of heat dissipation holes 103 are provided on the outer side of the outer casing 1.

[0043] The working principle and usage process of this utility model are as follows: First, the sample is placed inside the placement tray 4 and the placement tray 4 is placed on the top plate 302. At this time, the second electric push rod 312 drives the toothed plate 311 to move and drives the driven gear 310 to rotate the rotating shaft 309, which in turn drives the drive plate 303 to rotate. This drives the slide rod 306 to slide inside the slide groove 305 through the drive groove 307, which in turn drives multiple sets of clamping blocks 304 to clamp the placement tray 4. At the same time, the first electric push rod 203 drives the mounting frame 202 to move downward, which in turn drives the low-speed motor 204 and the sample spreading rod 205 to move downward, so that the sample spreading rod 205 moves into the interior of the placement tray 4, thereby rotating to perform a pre-flattening operation on the sample, thereby reducing the overall time required for uniformly flattening the sample. After that, the vertical vibration controller 101 and the high-frequency electromagnetic oscillator 102 are started to vibrate the radioactive sample inside the placement tray 4, promoting the mixing and homogenization of the radioactive sample in the placement tray 4.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
