[0068] See also Figures 1 to 7 As shown, according to the first aspect of the present application, a dry rotary irradiation device is provided, comprising:

[0069] A rotating unit 1, wherein the rotating unit 1 is used to drive the irradiated specimen to rotate;

[0070] A shielding unit 2, the shielding unit 2 is arranged at one side of the rotating unit 1, and the shielding unit 2 includes a shielding box body 21 and a shielding door body 22;

[0071] A mobile unit is arranged inside the shielding box 21. A radiation source is placed on the mobile unit. When the shielding door 22 is opened, the mobile unit can drive the radiation source to move toward the irradiation specimen and irradiate the irradiation specimen.

[0072] Specifically, the shielding unit 2 is used to accommodate a radiation source.

When closed, it can further enhance the shielding effect and form a relatively closed and safe irradiation space; when irradiation operation is required, the shielding door 22 is opened to facilitate subsequent operations.

[0074] The rotating unit 1 is used to drive the irradiated specimen to rotate. The rotating unit 1 can make the irradiated specimen rotate continuously during the irradiation process, ensuring that all parts of the irradiated specimen have the opportunity to receive irradiation evenly, thereby effectively improving the irradiation uniformity.

[0075] The mobile unit is arranged inside the shielding box 21, and a radiation source is placed on the mobile unit. When the shielding door 22 is opened, the mobile unit can drive the radiation source to move toward the irradiated specimen and irradiate the irradiated specimen.

Since the rotating platform 14 performs a circular motion driven by the rotating assembly 13, the fixing assemblies 15 distributed in a circular shape can evenly apply a fixing force to the irradiated specimen placed on the rotating platform 14, thereby ensuring the stability of the irradiated specimen during the rotation process. Regardless of the rotation state of the rotating platform 14, the fixing assemblies 15 can effectively prevent the irradiated specimen from displacement, shaking, etc., thereby ensuring the uniformity of irradiation and the safety and accuracy of the entire irradiation process.

[0141] Step 3, opening the shielding door 22, and the translation assembly 3 drives the radiation source to move toward the radiation test piece and then stops;

[0142] Specifically, after the irradiation specimen is fixed, the shielding door 22 is opened, and the translation assembly 3 drives the radiation source placed on the support assembly 4 to move toward the irradiation specimen. When the radiation source moves to a suitable position from the irradiation specimen according to a predetermined distance, the translation assembly 3 stops moving to ensure that the relative position between the radiation source and the irradiation specimen meets the requirements of the irradiation experiment, providing accurate starting conditions for subsequent irradiation operations, thereby ensuring that the irradiation process can be carried out under precisely controlled parameters, and ultimately obtaining reliable irradiation results.

[0143] Step 4: The rotating unit 1 drives the irradiated specimen to rotate, so that the radiation source irradiates the irradiated specimen.

[0144] Specifically, after the position of the radiation source is adjusted, the first driving member 133 can drive the turntable 132 and the rotating platform 14 to rotate through the driving gear 134, and then drive the irradiated specimen to rotate. In this process, since the rotation of the rotating platform 14 is precisely controlled by the rotating component 13, the irradiated specimen can rotate at a stable speed and a uniform trajectory. While the rotating unit 1 drives the irradiated specimen to rotate, the radiation source is already in a suitable position under the operation of the previous translation component 3. As the irradiated specimen rotates, the radiation source irradiates the irradiated specimen. Since all parts of the irradiated specimen can evenly pass through the radiation area of ​​the radiation source during the rotation process, uniform irradiation of the irradiated specimen can be achieved. This uniform irradiation helps to improve the accuracy and reliability of the irradiation results.
