Description

Technical Field

[0001] This utility model relates to the field of radiation gradient detection technology, specifically to a trapezoidal support for an electron accelerator. Background Technology

[0002] Electron accelerators have been widely used in medical and industrial fields, and the radiation they generate requires gradient measurement. Thin-film chromogenic dosimeters are radiation dose measurement devices based on radiochromic materials. Their core principle is that when a material is exposed to radiation, its molecular structure changes, resulting in a linear or non-linear relationship between color intensity and radiation dose. By measuring the color change, the radiation dose value can be directly calculated. Electron accelerator height dose distribution measurement refers to the quantitative analysis of the dose intensity distribution characteristics of the electron beam along the vertical direction (height dimension) within the accelerator cavity or irradiation space.

[0003] A search revealed a patent document with application number 202421064025.3, which discloses a trapezoidal support for an electron accelerator, comprising: a cross-shaped support, several gradient plates, a marking ring, and a clamping structure. Although the trapezoidal support of the electron accelerator provides a dosimeter mounting position for each gradient plate and creates a distance gradient, allowing for the measurement of the electron accelerator height dose distribution after the dosimeter is mounted to the gradient plate using a clamping structure, the gradient plates on the trapezoidal support are arranged in a staggered, layered manner. This layout results in significant differences in the distance between the chromogenic film dosimeter mounted on each gradient plate and the electron accelerator emission source. According to the physical characteristics of radiation propagation, radiation attenuates with increasing distance during transmission, following the inverse square law. Dosimeters closer to the emission source receive higher radiation intensity, while dosimeters farther away receive lower doses due to radiation attenuation. This dose deviation renders the measurement results from different gradient plates incomparable.

[0004] Therefore, we propose a trapezoidal support for an electron accelerator. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a trapezoidal support for an electron accelerator, which solves the problem that the gradient plates in existing devices are distributed front and back, resulting in inconsistent distances between the colorimetric film dosimeters on each gradient plate and the electron accelerator during measurement, leading to large measurement errors and inaccurate measurement results.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an electron accelerator trapezoidal support, including an isosceles trapezoidal vertical plate, a linear array of sliding grooves is provided in the middle of the front side of the vertical plate, a height adjustment component is provided in the sliding groove, and a placement component is provided in front of the height adjustment component; The height adjustment assembly includes a threaded rod and a slider. The threaded rod is rotatably mounted inside the slide groove via a bearing ring, and the slider is threadedly fitted onto the outer surface of the threaded rod and slidably fitted inside the slide groove. The placement assembly includes a placement plate and a snap-fit ​​plate. The placement plate is fixedly installed on the front side wall of the slider, and a snap-fit ​​plate with an "L" shaped cross-section is fixedly installed on the front side of the placement plate.

[0007] Preferably, the top of the threaded rod extends above the vertical plate and is fixedly mounted with a knob. The knob has anti-slip grooves arranged in a circular array on its side wall, which facilitates the rotation of the threaded rod.

[0008] Preferably, the front side of the vertical plate is provided with scale grooves located on the left and right sides of the slide groove, wherein the scale grooves facilitate observation and measurement of the height of the placed component.

[0009] Preferably, a rangefinder is fixedly installed at both the left and right ends of the front side of the vertical plate, which facilitates the measurement of the distance between the vertical plate and the electron accelerator emission source.

[0010] Preferably, the vertical plate is fixedly installed on the middle of the top surface of the chassis, and an annular anti-slip pad is fixedly installed on the bottom surface of the chassis. The chassis supports the vertical plate, and the anti-slip pad can increase the friction at the bottom of the chassis, thereby increasing the stability of the chassis and the vertical plate.

[0011] This invention provides a trapezoidal support for an electron accelerator. It offers the following advantages: This trapezoidal support for the electron accelerator allows for height adjustment of the placement components, facilitating the measurement of the electron accelerator's height dose distribution. Furthermore, the thin-film chromogenic dosimeters on each placement component are located on the plane in front of the vertical plate, preventing inaccurate measurements due to inconsistent distances between the chromogenic dosimeters and the electron accelerator at different locations. This solves the problem of inconsistent distances between the chromogenic dosimeters and the electron accelerator on each gradient plate in existing devices, leading to large measurement errors and inaccurate results.

[0015] Example 1: like Figure 1-4 As shown: It includes a vertical plate 2 in the shape of an isosceles trapezoid, and a slide groove 21 distributed in a linear array is provided in the middle of the front side of the vertical plate 2. A height adjustment component 3 is provided in the middle of the slide groove 21, and a placement component 4 is provided in front of the height adjustment component 3. The height adjustment assembly 3 includes a threaded rod 31 and a slider 32. The threaded rod 31 is rotatably mounted inside the slide groove 21 via a bearing ring. The slider 32 is threadedly fitted onto the outer surface of the threaded rod 31 and slidably fitted inside the slide groove 21. The placement assembly 4 includes a placement plate 41 and a snap-fit ​​plate 42. The placement plate 41 is fixedly installed on the front side wall of the slider 32, and the snap-fit ​​plate 42 with an "L" shaped cross section is fixedly installed on the front side of the placement plate 41. The height of the placement component 4 is adjusted by the height adjustment component 3, which facilitates the adjustment of the height of the thin film colorimetric dosimeter at each position, so as to facilitate the measurement of the height dose distribution of the electron accelerator. In addition, the thin film colorimetric dosimeters on each placement component 4 are located on the plane in front of the vertical plate 2, which avoids the situation where the distance between the colorimetric thin film dosimeters at different positions and the electron accelerator is inconsistent, resulting in inaccurate measurement results.

[0016] Furthermore, the top of the threaded rod 31 extends to the top of the vertical plate 2 and is fixedly mounted with a knob 33. The knob 33 has anti-slip grooves arranged in a ring array on its side wall. The knob 33 facilitates the rotation of the threaded rod 31.

[0019] Furthermore, the vertical plate 2 is fixedly installed on the middle of the top surface of the chassis 1, and a ring-shaped anti-slip pad 6 is fixedly installed on the bottom surface of the chassis 1. The chassis 1 supports the vertical plate 2, and the anti-slip pad 6 increases the friction at the bottom of the chassis 1, thereby increasing the stability of the chassis 1 and the vertical plate 2.

[0020] The working principle and usage process of this utility model are as follows: When using this trapezoidal support for an electron accelerator, the support is placed in front of the electron accelerator emission source. The distance between the support and the electron accelerator is measured by the rangefinder 5. Then, the thin film colorimetric dosimeter is placed inside the snap-fit ​​plate 42. Then, the screw rod 31 is rotated by the knob 33 to adjust the sliders 32, the placement components 4 and the thin film colorimetric dosimeter to different heights. Then, the electron accelerator is turned on to measure the height dose distribution of the electron accelerator. After a period of time, the radiation dose value is calculated by observing and comparing the color change of the thin film colorimetric dosimeter.
