[0068] See also Figures 1 to 7 As shown, a dry rotating irradiation apparatus is provided according to a first aspect embodiment of this application, comprising:

[0069] Rotating unit 1, which is used to drive the irradiated specimen to rotate;

[0070] Shielding unit 2, which is disposed on one side of the rotating unit 1, includes a shielding box 21 and a shielding door 22;

[0071] A mobile unit is disposed inside the shielded enclosure 21. A radiation source is placed on the mobile unit. When the shielded door 22 is opened, the mobile unit can move the radiation source toward the irradiated specimen and irradiate the specimen.

[0072] Specifically, the shielding unit 2 is used to contain the radiation source. When not in use, the radiation source is located inside the shielding box 21, and the shielding door 22 is in a closed state to achieve radiation shielding of the radiation source. When in use, the shielding door 22 is in an open state, and the moving unit drives the radiation source to move toward the irradiated specimen and stops after it is close to the irradiated specimen. At this time, the rotating unit 1 is responsible for driving the irradiated specimen to rotate so as to achieve uniform irradiation of the irradiated specimen.

[0073] Both the shielding enclosure 21 and the shielding door 22 are composed of a stainless steel shell and a lead-filled layer, which can effectively block the radiation generated by the radiation source, prevent radiation leakage into the surrounding environment, and ensure the safety of operators and the surrounding environment. The shielding door 22 fits tightly with the shielding enclosure 21. When closed, it can further enhance the shielding effect, forming a relatively closed and safe irradiation space. When irradiation operations are 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 enables the irradiated specimen to 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 uniformity of irradiation.

[0075] The movable unit is located inside the shielded enclosure 21, and a radiation source is placed on the movable unit. When the shielded door 22 is opened, the movable unit can move the radiation source toward the irradiated specimen and irradiate it. This movable radiation source design, combined with the rotation unit 1 that rotates the irradiated specimen, can better adapt to the irradiation requirements of the specimen. The movable unit can precisely control the movement path and speed of the radiation source, ensuring it accurately reaches the optimal position corresponding to the irradiated specimen, thereby further optimizing the irradiation effect and meeting the irradiation requirements.

[0076] The radioactive source is a radioactive gamma source.

[0077] The rotating unit 1 includes:

[0078] Supporting framework 11;

[0079] Protective cover 12, the protective cover 12 is disposed on the outside of the support frame 11, and the protective cover 12 is provided with mounting holes;

[0080] Rotating assembly 13, wherein the rotating assembly 13 is disposed within the support frame 11;

[0081] A rotating platform 14 is disposed on the rotating assembly 13 and located within the mounting hole. The rotating assembly 13 is used to drive the rotating platform 14 to rotate, and the irradiated specimen is disposed on the rotating platform 14.

[0082] Specifically, the rotating unit 1 includes a support frame 11, which provides stable support for other components within the rotating unit 1. A protective cover 12 is disposed outside the support frame 11, preventing external dust, impurities, and other foreign objects from entering the support frame 11 and avoiding contamination or damage to the internal rotating component 13 and rotating platform 14. The protective cover 12 has mounting holes, and the rotating platform 14 is mounted on the rotating component 13 and located within the mounting holes, achieving a tight fit between the rotating platform 14 and the protective cover 12, further reducing the entry of external impurities into the support frame 11. The rotating component 13 can drive the rotating platform 14 to rotate, and it can provide a suitable rotational speed, thereby ensuring that the irradiated specimen rotates at a predetermined speed on the rotating platform 14 to achieve uniform irradiation.

[0083] The rotating assembly 13 includes:

[0084] Rotary base 131;

[0085] A rotary disk 132 is rotatably mounted on a rotary base 131, and a rotary platform 14 is mounted on the rotary disk 132. The outer circumference of the rotary disk 132 is provided with external teeth.

[0086] The first driving component 133 is disposed on one side of the rotary base 131;

[0087] A drive gear 134 is connected to the output end of the first drive member 133, and the drive gear 134 is meshed with the external teeth on the rotary table 132.

[0088] Specifically, the rotating assembly 13 includes a rotating base 131, which is the basic support structure for the entire rotating assembly 13. It provides a stable mounting base for the rotary disk 132, ensuring the relative position stability of these components during operation, thereby guaranteeing the overall operational reliability of the rotating assembly 13. The rotary disk 132 is rotatably mounted on the rotary base 131. Furthermore, the rotary disk 132 can be connected to the rotary base 131 via a centrally mounted shaft, achieving a rotatable connection of the rotary disk 132 on the rotary base 131. The rotating platform 14 is mounted on the rotary disk 132, so the rotation of the rotary disk 132 directly drives the rotating platform 14 and the irradiated specimen on it to rotate. The outer circumference of the rotary disk 132 is provided with external teeth. A first driving member 133 is located on one side of the rotary base 131, and the first driving member 133 is the power source for the rotating assembly 13. It adopts a driving technology suitable for the requirements of this device, such as a high-precision motor or other forms of power generation device. The power generated by the first driving component 133 is transmitted to the rotary table 132 through the driving gear 134, causing the rotary table 132 to rotate at a predetermined speed and direction, thereby driving the irradiated specimen to rotate uniformly on the rotary platform 14.

[0089] The rotating unit 1 further includes:

[0090] Fixing components 15, a plurality of fixing components 15 are arranged in a circle on the rotating platform 14, for fixing the irradiated specimen;

[0091] The fixing component 15 includes:

[0092] A fixing plate 151 is disposed on the rotary platform 14;

[0093] A fastening screw 152 is mounted on the fixing plate 151.

[0094] Specifically, the rotating unit 1 also includes fixing components 15. Multiple fixing components 15 are arranged in a circular pattern on the rotating platform 14. Since the rotating platform 14 moves in a circular motion driven by the rotating component 13, the circularly arranged fixing components 15 can uniformly apply a fixing force to the irradiated specimen placed on the rotating platform 14, thereby ensuring the stability of the irradiated specimen during rotation. Regardless of the rotation state of the rotating platform 14, the fixing components 15 can effectively prevent displacement or shaking of the irradiated specimen, thus ensuring the uniformity of irradiation and the safety and accuracy of the entire irradiation process.

[0095] Furthermore, the fixing component 15 includes a fixing plate 151 and a fastening screw 152. The fixing plate 151 is mounted on the rotary platform 14. The shape, size, and connection method of the fixing plate 151 to the rotary platform 14 are all set according to the usage requirements. The fastening screw 152 is mounted on the fixing plate 151 and the tightness can be adjusted by rotation to firmly fix the irradiated specimen. The thread design, length, and head structure of the fastening screw 152 are all matched to the fixing requirements of the irradiated specimen. In actual operation, the operator can reasonably adjust the tightness of the fastening screw 152 according to factors such as the size, shape, and material of the irradiated specimen to ensure that the irradiated specimen is firmly fixed on the rotary platform 14, thereby meeting the needs of different irradiation scenarios and ensuring the smooth progress of the irradiation process.

[0096] The mobile unit includes:

[0097] Translation component 3, which is disposed inside the shielding box 21;

[0098] Support component 4 is disposed on the translation component 3 and is used to support the radiation source.

[0099] Specifically, the moving unit includes a translation component 3 and a support component 4. The translation component 3 is disposed within the shielding enclosure 21. The translation component 3 is used to move the radiation source toward the irradiated specimen, adjusting the distance between the irradiated specimen and the radiation source according to actual needs, thereby improving irradiation efficiency. The support component 4 is disposed on the translation component 3 and plays a crucial role in supporting the radiation source within the moving unit.

[0100] The translation component 3 includes:

[0101] Base plate 31, which is disposed inside the shielding box 21;

[0102] The first slide rail 32 is disposed on the base plate 31;

[0103] Mounting base 33, which is slidably disposed on the first slide rail 32;

[0104] A transmission screw 34 is mounted on the base plate 31 and connected to the mounting base 33;

[0105] The first fast interface 35 is disposed on the shielding box 21 and connected to the transmission lead screw 34.

[0106] Specifically, the translation component 3 consists of a base plate 31, a first slide rail 32, a mounting base 33, a transmission screw 34, and a first quick-connect interface 35. The first quick-connect interface 35 is connected to an external power device, which can drive the transmission screw 34 to rotate, thereby driving the mounting base 33 to move horizontally on the first slide rail 32, realizing the horizontal movement of the radiation source within the shielding box 21, and improving the accuracy of irradiating the irradiated specimen.

[0107] The base plate 31 is housed within the shielding enclosure 21, providing a stable mounting foundation for the entire translation assembly 3. The base plate 31 can be made of a high-strength, radiation-resistant metal material to ensure it will not deform or be damaged during long-term use. The base plate 31 can be connected to the shielding enclosure 21 by bolts or welding.

[0108] There are two first slide rails 32, which are symmetrically installed on the base plate 31. The mounting base 33 is slidably installed on the first slide rails 32. The bottom of the mounting base 33 is provided with a slider structure that matches the first slide rails 32. The slider's dimensional accuracy, shape tolerance, and surface roughness are all carefully designed to ensure that the sliding fit accuracy between it and the first slide rails 32 is within a very small tolerance range.

[0109] The transmission screw 34 is mounted on the base plate 31 and connected to the mounting base 33. The first quick-connect interface 35 is mounted on the shielded enclosure 21 and connected to the transmission screw 34. The main function of the first quick-connect interface 35 is to provide an external power input interface for the transmission screw 34. Its design facilitates quick connection with external power equipment (such as motors) to realize the rotation of the transmission screw 34. The first quick-connect interface 35 ensures effective power transmission and has a certain sealing performance to prevent the special environment inside the shielded enclosure 21 (such as radiation, dust, etc.) from affecting the interface connection.

[0110] The support component 4 includes:

[0111] Push plate 41, the push plate 41 is disposed on the mounting base 33;

[0112] Support cylinder 42, a plurality of support cylinders 42 are inclinedly disposed on push plate 41, and a guide port 43 is provided at the end of the support cylinder 42 away from push plate 41;

[0113] Reinforcing ring 44, wherein the reinforcing ring 44 is disposed between the plurality of supporting cylinders 42;

[0114] A reinforcing rib 45 is disposed between the push plate 41 and the support cylinder 42.

[0115] Specifically, the support component 4 includes a push plate 41, a support cylinder 42, a guide port 43, a reinforcing ring 44, and a reinforcing rib 45. The push plate 41 is stably connected to the translation component 3. The radiation source is placed into the support cylinder 42 through the guide port 43 to achieve the bearing and fixation of the radiation source. The reinforcing ring 44 enhances the overall structural strength between the support cylinders 42, and the reinforcing rib 45 strengthens the connection between the push plate 41 and the support cylinder 42. All parts cooperate with each other to achieve stable bearing of the radiation source.

[0116] The push plate 41 is connected to the translation component 3, and its upper surface is used for mounting the support cylinder 42. The support cylinder 42 is the part of the support component 4 that directly contacts and supports the radiation source. Multiple support cylinders 42 are inclinedly arranged on the push plate 41. This inclined arrangement improves the stability after the radiation source is placed. A guide port 43 is provided at the end of the support cylinder 42 away from the push plate 41. The guide port 43 facilitates the placement of the radiation source and provides initial positioning. The shape and size of the guide port 43 match the shape of the radiation source. For example, if the radiation source is cylindrical, the guide port 43 may be semi-circular or circular to accurately guide the radiation source into the interior of the support cylinder 42 during placement.

[0117] The reinforcing ring 44 is disposed between multiple support cylinders 42, connecting the multiple support cylinders 42 together to form an organic whole structure, thereby enhancing the overall structural strength. Through the connection of the reinforcing ring 44, the cooperative working ability among the multiple support cylinders 42 is improved, thereby increasing the load-bearing capacity and stability of the entire support assembly 4 for the radiation source.

[0118] A reinforcing rib 45 is positioned between the push plate 41 and the support cylinder 42 to enhance the connection strength between them. This ensures that the force borne by the support cylinder 42 can be effectively transmitted to the push plate 41, and subsequently to the mounting base 33 and the translation assembly 3. The reinforcing rib 45 improves the structural integrity of the entire support assembly 4, enabling it to maintain stable structural performance while bearing the radiation source and moving with the translation assembly 3, thus guaranteeing the safe and precise movement of the radiation source.

[0119] It also includes a lifting component 5, which includes:

[0120] The bracket body 51 is disposed on the shielding box 21;

[0121] The second slide rail 52 is disposed on the shielding box 21 and the bracket body 51;

[0122] The slide plate 53 is slidably disposed on the second slide rail 52 and is connected to the shielding door body 22;

[0123] Connector 54, the connector 54 being disposed on the shielding housing 21;

[0124] A drive screw 55 is disposed between the bracket body 51 and the connector 54, and the drive screw 55 is connected to the shielding door body 22;

[0125] The second quick connector 56 is disposed on the shielding housing 21, and a connecting rod 57 is provided between the second quick connector 56 and the connector 54.

[0126] Specifically, the lifting component 5 is connected to the second quick connector via an external power source, which can transmit power to the drive screw 55 through the connecting rod 57, causing the drive screw 55 to rotate, thereby driving the shielding door 22 to move up and down, making it convenient to open the shielding door 22 according to the usage situation, and the operation is convenient.

[0127] The second quick connector 56 is installed on the shielded enclosure 21. The main function of the second quick connector 56 is to provide an external power input interface or a connection interface for other external devices. Its design facilitates quick connection with external power equipment (such as motors) or other auxiliary equipment, thereby driving the connecting rod 57 to rotate.

[0128] The connector 54 is mounted on the shielded enclosure 21, and the connecting rod 57 is connected to the drive screw 55 through the connector 54 to transmit power. The connector 54 may employ a special threaded structure or keyed connection to ensure that when the connecting rod 57 rotates, it can accurately drive the connector 54 and the drive screw 55 to perform corresponding movements.

[0129] The drive screw 55 is located between the bracket body 51 and the connector 54 and is connected to the shielding door body 22. When the drive screw 55 rotates, it can drive the shielding door body 22 to move up and down along the second slide rail 52.

[0130] The bracket body 51 is mounted on the shielding box 21 to provide a support base. The second slide rail 52 is installed on the shielding box 21 and the bracket body 51 and is located on both sides of the shielding door 22. It is used as a guide and limiting structure for the sliding of the slide plate 53.

[0131] The connector 54 includes:

[0132] A sealed box, which is disposed on the shielding box 21;

[0133] The first bevel gear is disposed inside the sealed box and is connected to the drive screw 55;

[0134] The second bevel gear meshes with the first bevel gear and is connected to the connecting rod 57.

[0135] Specifically, the connector 54 includes a sealing box, a first bevel gear, and a second bevel gear. Through the meshing connection of the first bevel gear and the second bevel gear, the rotation of the connecting rod 57 can be transmitted to the second bevel gear, and then transmitted to the drive screw 55 through the first bevel gear, thereby realizing the transmission of power.

[0136] This application also provides a dry rotary irradiation method, employing the dry rotary irradiation apparatus of any embodiment of the first aspect, comprising the following steps:

[0137] Step 1: The radiation source is installed on the support assembly 4, the translation assembly 3 moves the radiation source into the shielding box 21, and closes the shielding door 22;

[0138] Specifically, before use, the radiation source needs to be placed inside the shielding enclosure 21. The shielding door 22 is opened by the support assembly 4, exposing the translation assembly 3 and the support assembly 4. The translation assembly 3 then moves the support assembly 4 outwards from the shielding enclosure 21, allowing the radiation source to be placed onto the support assembly 4. The translation assembly 3 then begins to function, moving the radiation source into the shielding enclosure 21. After the radiation source is inside the shielding enclosure 21, the shielding door 22 is closed. This effectively blocks the radiation generated by the radiation source, preventing radiation leakage into the surrounding environment and ensuring the safety of the operators and the surrounding environment.

[0139] Step 2: Install the irradiated specimen onto the rotary platform 14;

[0140] Specifically, the irradiated specimen is hoisted onto the rotating platform 14, and the irradiated specimen is fixed onto the rotating platform 14 by adjusting the fixing component 15. During this process, it is important to ensure that the irradiated specimen is firmly fixed, but not too tightly, which could cause the irradiated specimen to be subjected to unnecessary pressure or deformation.

[0141] Step 3: Open the shielding door 22, and the translation component 3 moves the radiation source toward the radiation specimen and then stops;

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

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

[0144] Specifically, after the radiation source position is adjusted, the first driving component 133 drives the rotary table 132 and the rotary platform 14 to rotate via the driving gear 134, thereby causing the irradiated specimen to rotate. During this process, since the rotation of the rotary platform 14 is precisely controlled by the rotating component 13, the irradiated specimen can rotate at a stable speed and along a uniform trajectory. While the rotating unit 1 drives the irradiated specimen to rotate, the radiation source is already in the appropriate position thanks to the previous operation of the translation component 3. As the irradiated specimen rotates, the radiation source irradiates it. Because all parts of the irradiated specimen can pass uniformly through the radiation area of ​​the radiation source during rotation, uniform irradiation of the irradiated specimen can be achieved. This uniform irradiation helps improve the accuracy and reliability of the irradiation results.
