[0030] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. In the description of the present invention, it should be noted that the term "or" is generally used in the sense of including "and / or" unless the content clearly indicates otherwise.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or a magnetic connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be a connection between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In addition, in the description of this application, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three or more, etc., unless otherwise clearly specified and limited.

[0032] Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] First, to facilitate understanding of the embodiments of the present invention, some of the terms or nouns involved in the present invention are explained below:

[0034] An operating hot chamber refers to a shielded room for conducting high-radioactivity tests and operations. It is isolated from the surrounding environment to prevent radioactive substances from causing harm to the external environment and personnel.

[0035] An operating glove hole is a hole opened on the surface of glass (such as tempered glass, lined glass, etc.). Its size and shape are designed to be large enough for a person's arm to pass through in order to perform various operations.

[0036] In order to solve the problems existing in the prior art, the embodiments of the present application provide a fan-shaped material sample transport device and method.

[0037] Example 1

[0038] This embodiment provides a fan-shaped material sample transport device, such as Figure 1 As shown, Figure 1 1 is a schematic structural diagram of a fan-shaped material sample transport device in Example 1 of the present invention, the device comprising:

[0039] Shielding walls 1, which are interconnected to form multiple operating hot chambers 11; a rotating inner cavity 12, which is arranged at the center of the multiple operating hot chambers 11, and the multiple operating hot chambers 11 are evenly distributed around the rotating inner cavity 12; a sample transport component 21, which is arranged in the rotating inner cavity 12, is used to drive the material sample to rotate and transport it to the first operating hot chamber, wherein the first operating hot chamber is used to indicate the operating hot chamber to which the material sample needs to be transported; a robotic arm 31, which is arranged on the shielding wall 1 and is located in the first operating hot chamber, is used to take the material sample transported by the sample transport component 21.

[0040] Based on the above structure, since most material samples are radioactive, a shielding wall 1 is required to be set up, and the material samples are placed in the operating hot chamber 11 formed by the shielding wall 1. The staff uses the robotic arm 31 to detect and analyze the material samples outside the operating hot chamber 11, which effectively reduces the radiation level of the material samples to the staff and ensures the safety of the staff.

[0041] Optionally, since different instruments may be needed or different methods may be needed in the process of analyzing material samples, in order to avoid mutual interference between different instruments or different detection methods, it is necessary to use a shielding wall 1 to divide the operating hot chamber into multiple operating hot chambers 11, and different instruments are stored in the multiple operating hot chambers 11 to perform different analysis experiments.

[0042] Optionally, multiple operating hot chambers 11 are distributed in a surrounding shape. Taking four operating hot chambers as an example, the four operating hot chambers are placed on the four corners of a quadrilateral. If there are five operating hot chambers 11, the five operating hot chambers 11 can be divided into five equal parts from the center to the corners in the form of an equilateral pentagon. A rotating inner cavity 12 is set at the center of the multiple operating hot chambers 11. Since the multiple operating hot chambers 11 are distributed in a manner surrounding the rotating inner cavity 12, each operating hot chamber will be in contact with and connected to the rotating inner cavity 12, that is, any operating hot chamber of the multiple operating hot chambers 11 is only separated from the rotating inner cavity 12 by a shielding wall 1, which effectively realizes that the material sample transported by the rotating inner cavity 12 can be transported to any operating hot chamber.

[0043] Optionally, a sample transport assembly 21 is placed in the rotating inner cavity 12. The sample transport assembly 21 can remove a material sample from one of the operating hot chambers 11 and place it in the rotating inner cavity 12. The sample sample is then rotated in the rotating inner cavity 12 in the direction of the first operating hot chamber, thereby effectively transporting the material sample. At the same time, transport based on the sample transport assembly 21 effectively avoids workers from contacting the material sample, reduces the risk of workers being affected by radioactive interference, and improves the safety of the environment in which the workers are located.

[0044] Optionally, the sample transfer component 21 transfers the material sample to the first operating hot chamber, and the staff operates the robotic arm 31 outside the first operating hot chamber to take the material sample out of the sample transfer component 21, and operates the robotic arm 31 to perform an analysis experiment in the first operating hot chamber. During the entire process, the staff does not touch the material sample, which effectively reduces the risk of the staff being interfered with by radioactivity, thereby improving the safety of the staff during work.

[0045] like Figure 2 As shown, Figure 2 It is a structural schematic diagram of a sample transport component 21 in a fan-shaped material sample transport device in Example 1 of the present invention. In some preferred embodiments, the sample transport component 21 includes: a telescopic arm 22, used to push the material sample from the rotating inner cavity 12 to the first operating hot chamber; a rotating shaft 23, arranged at the central axis of the rotating inner cavity 12, connected to the telescopic arm 22, and used to drive the telescopic arm 22 to rotate between different directions of multiple operating hot chambers 11 until it rotates to the direction toward the first operating hot chamber.

[0046] Based on the above structure, the sample transport assembly 21 needs to rotate within the rotating inner chamber 12 to move the material sample from the operating hot chamber to the first operating hot chamber. Therefore, a rotating shaft 23 is required. The rotating shaft 23 drives the material sample to rotate from the operating hot chamber to the direction corresponding to the first operating hot chamber, thereby realizing the rotational transportation of the material sample. The rotating shaft 23 is fixed to the center of the rotating inner chamber 12 by anchor bolts. The rotating shaft 23 includes a fixed end and a rotating end. The fixed end is fixedly mounted to the rotating inner chamber 12, and the rotating end is movably connected to the fixed end. The rotating end can rotate 360 degrees relative to the fixed end.

[0047] Optionally, after the rotating shaft 23 drives the material sample to rotate into the first operating hot chamber, the telescopic arm 22 pushes the material sample from the rotating inner cavity 12 to the interior of the first operating hot chamber, thereby transferring the material sample from the current operating hot chamber to the first operating hot chamber. The telescopic arm 22 can be a cylinder, with the barrel of the cylinder fixedly mounted on the rotating shaft 23 and the piston of the cylinder connected to the material sample. The piston can be extended or retracted relative to the barrel to push the material sample.

[0048] In some preferred embodiments, the sample transport component 21 further includes: a transport inner cylinder 24 fixedly connected to the telescopic arm 22 for loading material samples.

[0049] Based on the above structure, since the material samples are of varying sizes and shapes, a fixed device is required when the piston portion of the cylinder is connected to the material sample, namely, a transfer inner cylinder 24. The transfer inner cylinder 24 is fixedly mounted on the piston portion, and the material sample is placed in the transfer inner cylinder 24. When the telescopic arm 22 pushes the transfer inner cylinder 24 to move, the material sample is moved, effectively achieving the effect of transferring the material sample from the operating hot chamber to the first operating hot chamber.

[0050] Optionally, the shape of the transfer inner cylinder 24 can be a cube or a cylinder. Since the outer surface of the rotating inner cavity 12 is a cylinder, setting the transfer inner cylinder 24 as a cylinder can effectively increase the area utilization rate. During the rotation of the transfer inner cylinder 24 in the rotating inner cavity 12, the distance between the closest edges of the two remains unchanged, avoiding the phenomenon of increasing the spacing distance and wasting area, thereby effectively improving the area utilization rate.

[0051] In some preferred embodiments, it also includes: an electric shielding door 13, installed on the wall of the rotating inner cavity 12, located at the connection between the multiple operating hot chambers 11 and the rotating inner cavity 12, and used to connect the multiple operating hot chambers 11 and the rotating inner cavity 12 when the telescopic arm 22 is working; a processor, connected to the rotating shaft 23, the telescopic arm 22 and the electric shielding door 13, used to control the rotation angle of the rotating shaft 23, control the opening and closing of the telescopic arm 22, and control the opening and closing of the electric shielding door 13 based on the opening and closing of the telescopic arm 22.

[0052] Based on the above structure, in order to avoid the connection between multiple operating hot chambers 11 and the rotating inner cavity 12 being in a connected state all the time, affecting the analysis effect of the experiment in the first operating hot chamber, it is necessary to set a shielding wall 1 between the multiple operating hot chambers 11 and the rotating inner cavity 12, and at the same time set an electric shielding door 13 so that the telescopic arm 22 can enter the first operating hot chamber based on the electric shielding door 13.

[0053] Optionally, the processor controls the rotation angle of the rotating shaft 23 according to a preset angle value set in advance, so that the rotating shaft 23 drives the telescopic arm 22 to rotate to the corresponding direction of the first operating hot chamber. The processor determines the current orientation of the first operating hot chamber based on the preset angle value, and at the same time controls the electric shielding door 13 corresponding to the first operating hot chamber to open, so that the telescopic arm 22 extends into the first operating hot chamber, so as to achieve the effect of moving the material sample to the first operating hot chamber.

[0054] Optionally, the staff controls the robotic arm 31 in the first operating hot chamber to clamp the material sample in the transfer inner cylinder 24, and places the material sample on the detection instrument through the robotic arm 31, and performs detection at the same time. The staff does not need to enter the first operating hot chamber to complete various detection processes, realize comprehensive analysis of the material samples, and effectively reduce the risk of radiation exposure to the staff.

[0055] In some preferred embodiments, it also includes: an operating glove hole 14, which is set on the shielding wall 1, connecting the multiple operating hot chambers 11 with the external environment, and the multiple operating hot chambers 11 are each provided with an operating glove hole 14. The operating glove hole 14 is used for the robot arm 31 to penetrate the multiple operating hot chambers 11 from the external environment.

[0056] Based on the above structure, to allow workers to operate the robotic arm 31, the robotic arm 31 is extended from the first operating hot chamber to the outside environment. The worker can control the robotic arm 31 from the outside environment, effectively reducing the risk of radiation exposure to the worker. The shielding wall 1 is provided with an operating glove hole 14, through which the robotic arm 31 passes to connect the first operating hot chamber with the outside environment, effectively enabling workers to complete analysis and testing without entering the first operating hot chamber.

[0057] Alternatively, glove holes 14 may be provided in each of the multiple operating hot chambers 11. A set of robotic arms 31 may be used. After use of the original operating hot chamber, the robotic arms 31 may be removed through the glove holes 14 and placed in the glove holes 14 of the first operating hot chamber. This allows for the reuse of the set of robotic arms 31, reducing equipment costs. Alternatively, a set of robotic arms 31 may be provided in the glove holes of each operating hot chamber. This approach eliminates the need to move the robotic arms 31, reduces staff workload, and improves detection and analysis efficiency.

[0058] like Figure 3 As shown, Figure 3 FIG2 is a schematic diagram of the structure of a robotic arm 31 in a fan-shaped material sample transport device according to Example 1 of the present invention. In some preferred embodiments, the robotic arm 31 includes: an extension rod 32 having a length greater than or equal to a first predetermined distance, wherein the first predetermined distance indicates the distance between the operating glove hole 14 and the sample transport assembly 21 after the sample transport assembly 21 is extended into the first operating hot chamber; and a gripping hand 33 mounted at the end of the extension rod 32 and positioned within the first operating hot chamber for gripping the material sample.

[0059] Based on the above mechanism, the extended connecting rod 32 can connect the distance from the operating glove hole 14 to the transfer inner cylinder 24. The extended connecting rod 32 can be provided with a movable joint, which uses a 360-degree rotating electric universal joint, that is, a ball and socket combined with a ball head. The use of a movable joint allows the extended connecting rod 32 to rotate, making it easier and more precise to access material samples at multiple angles. At the same time, a movable joint is provided at the connection between the clamping hand 33 and the extended connecting rod 32, allowing the clamping hand 33 to rotate relative to the extended connecting rod 32, effectively achieving the rotation of the clamping hand 33 and making it easier and more precise to access material samples at multiple angles.

[0060] Optionally, based on the function of the extended connecting rod 32, the staff can touch the material sample in the transfer inner cylinder 24 in the external environment. A clamping hand 33 is set at the end of the extended connecting rod 32. The clamping hand 33 includes a first clamping piece and a second clamping piece. The first clamping piece and the second clamping piece are symmetrically placed. When the clamping hand 33 touches the material sample, the first clamping piece and the second clamping piece shrink at the same time to clamp the material sample. The staff can operate the extended connecting rod 32 to move the clamping hand 33 away from the transfer inner cylinder 24, thereby effectively realizing the transfer of the material sample in the transfer inner cylinder 24.

[0061] Optionally, a clamping pad is provided at the end of each of the first and second clamping pieces, and the material sample is clamped by the clamping pad. If the material of the clamping hand 33 is too hard, the material sample may be broken during the clamping process. The clamping pad is provided. During the clamping process, due to the effect of the pad, the clamping pad can cushion the clamping force of the material sample by concaving when clamping force is applied, effectively avoiding the phenomenon of the material sample being broken. At the same time, the concavity between the clamping pad and the material sample during the clamping process can effectively support the material sample and prevent the material sample from falling during the clamping process.

[0062] Optionally, after the gripper 33 removes the sample material from the transfer inner cylinder 24, the telescopic arm 22 retracts the transfer inner cylinder 24 until the transfer inner cylinder 24 enters the rotating inner chamber 12. The processor then controls the electric shielding door 13 of the first operating hot chamber to close, completing the transfer of the sample material. After the electric shielding door 13 closes, the operator can operate the robotic arm 31 to place the sample material onto the testing instrument or perform a series of testing operations on the sample material to complete the analysis and testing of the sample material.

[0063] In some preferred embodiments, it further includes: a maintenance shielding door 15, which is arranged on the shielding wall 1 and connects the multiple operating hot chambers 11 with the external environment. The maintenance shielding doors 15 are correspondingly arranged on the multiple operating hot chambers 11.

[0064] Based on the above technical solution, during the process of the robot arm 31 testing the material sample, the material sample may fall, or the robot arm 31 may be unable to complete the action, resulting in the need for human intervention in the analysis and testing. Or, if the testing instrument malfunctions, it may require human intervention to enter the operating hot chamber for repair. In this case, the human intervention can enter the operating hot chamber through the maintenance shield door 15 to complete the task that the robot arm 31 was unable to complete.

[0065] It should be noted that since there are radioactive material samples in the operating hot chamber, as well as instruments that are exposed to sample radiation for a long time, the instruments may also be radioactive. Therefore, when workers enter the operating hot chamber, they need to wear complete protective suits to ensure their safety.

[0066] In some preferred embodiments, the shielding wall 1 is made of heavy concrete.

[0067] Based on the above structure, heavy concrete is a high-density concrete with a dry apparent density of more than 2800 kg / m 3 . It uses barite, iron ore, steel chips and the like as aggregates, and is formulated in combination with strontium cement or barium cement. Heavy concrete has the property of being opaque to X-rays and gamma rays, and can effectively absorb and shield nuclear radiation. Compared with shielding materials such as lead and steel, heavy concrete has the advantages of being cheap, easy to process and shape, and having high strength, which can reduce the cost of radiation protection. The greater the density and the thicker the heavy concrete shielding wall 1, the better its radiation protection effect. The heavy concrete shielding wall 1 has sufficient structural stability to withstand its own weight and external loads. Using heavy concrete material as the shielding wall 1 can effectively reduce the cost of use and has a good effect in reducing radiation.

[0068] In some preferred embodiments, the electric shield door 13 is made of lead metal.

[0069] Based on the above structure, lead metal is selected as the electric shielding door 13, which can effectively block the radioactivity of the material sample. The blocking effect of lead metal is high, and lead metal is relatively easy to obtain. The cost of use is lower than that of other metal materials, and the degree of protection is high, which effectively achieves the effect of reducing radiation.

[0070] Example 2

[0071] According to an embodiment of the present invention, a method for transporting a fan-shaped material sample is also provided. Figure 4 As shown, Figure 4 This is a flow chart of a fan-shaped material sample transport method in Example 2 of the present invention.

[0072] Step S11, the material sample is clamped by the robot arm 31 into the transfer inner cylinder 24;

[0073] Step S12: The telescopic arm 22 drives the transfer inner cylinder 24 from the second operating hot chamber into the rotating inner chamber 12, and the electric shield door 13 corresponding to the second operating hot chamber is closed. The second operating hot chamber is used to indicate other operating hot chambers except the first operating hot chamber.

[0074] Step S13: The rotating shaft 23 drives the telescopic arm 22 to rotate from the direction of the second operating hot chamber to the direction of the first operating hot chamber;

[0075] Step S14: The electric screen door 13 corresponding to the first operating hot chamber is opened, and the telescopic arm 22 drives the transfer inner cylinder 24 from the rotating inner cavity 12 into the first operating hot chamber;

[0076] Step S15: the robot arm 31 in the first operating hot chamber grips the material sample in the transfer inner cylinder 24 and places it in the first operating hot chamber;

[0077] In step S16, the telescopic arm 22 drives the transfer inner cylinder 24 from the first operating hot chamber into the rotating inner cavity 12, and the electric shielding door 13 corresponding to the first operating hot chamber is closed.

[0078] Through the above steps S11 to S16, the purpose of running the material sample in multiple operating hot chambers 11 through the sample transport component 21 is achieved, the staff operates the robotic arm 31 outside the first operating hot chamber to take the material sample out of the sample transport component 21, and the staff operates the robotic arm 31 to perform analytical experiments in the first operating hot chamber, thereby achieving the technical effect of not allowing the staff to contact the material sample, reducing the risk of the staff being interfered with by radioactivity, and improving the work safety of the staff, thereby solving the technical problem that the staff wearing protective clothing to transport samples between multiple different operating chambers can easily endanger the safety of the staff.

[0079] Example 3

[0080] Based on the above embodiments and optional embodiments, the present invention also proposes an optional implementation mode: Figure 5 Flowchart of an optional fan-shaped material sample transport method in Example 3 of the present invention, as shown in FIG. Figure 5 As shown, the method includes:

[0081] In step S21 , different operating hot chambers 11 are separated by shielding walls 1 .

[0082] Step S22, setting the rotating inner cavity 12 as the main space for moving the material sample, and placing the material sample into the transfer inner cylinder 24;

[0083] Step S23, by rotating the rotating shaft 23, the transfer inner cylinder 24 is directed to different directions, ready to enter different operating hot chambers;

[0084] Step S24, opening the electric screen door 13, extending the telescopic arm 22 so that the transfer inner cylinder 24 reaches the designated position in the first operating hot chamber;

[0085] Step S25, shortening the telescopic arm 22, closing the electric shielding door 13, and completing a material sample transfer process.

[0086] Through the above steps S21 to S25, the radioactive material samples are placed in the transfer inner cylinder 24 of the rotating inner cavity 12 and enter each operating hot chamber through automatic control, which effectively reduces the possibility of workers being exposed to radioactive radiation and improves the safety of workers.

[0087] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
