[0032] Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

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

[0034] A hot operating chamber is a shielded small room used for conducting high-radioactivity experiments and operations. It is isolated from the surrounding environment to prevent radioactive materials from harming the external environment and personnel.

[0035] An operating glove hole is a hole made in the surface of glass (such as tempered glass, enamel, etc.) that is designed in size and shape to allow a person's arm to pass through in order to perform various operations.

[0036] To address the problems existing in the prior art, this application provides a fan-shaped material sample transfer device and method.

[0037] Example 1

[0038] This embodiment provides a fan-shaped material sample transfer device, such as... Figure 1 As shown, Figure 1 This is a schematic diagram of a fan-shaped material sample transfer device according to Embodiment 1 of the present invention. The device includes:

[0039] A shielding wall 1 is interconnected to form multiple operating hot chambers 11; a rotating inner cavity 12 is located 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 transfer assembly 21 is located in the rotating inner cavity 12 and 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 transferred; a robotic arm 31 is located on the shielding wall 1 and in the first operating hot chamber, and is used to pick up the material sample transferred by the sample transfer assembly 21.

[0040] Based on the above structure, since most of the material samples are radioactive, it is necessary to set up a shielding wall 1 and place the material samples in the operating hot chamber 11 composed of the shielding wall 1. The staff can detect and analyze the material samples from outside the operating hot chamber 11 using a robotic arm 31, 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 or different methods may be required during the analysis of 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. Different instruments are placed in the multiple operating hot chambers 11 to conduct different analytical experiments.

[0042] Optionally, the multiple operating hot chambers 11 are distributed in a surrounding pattern. Taking four operating hot chambers as an example, the four operating hot chambers are placed at 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 around the rotating inner cavity 12, each operating hot chamber will be in contact with the rotating inner cavity 12. That is, any one of the multiple operating hot chambers 11 is separated from the rotating inner cavity 12 by only a shielding wall 1, which effectively enables the material sample transported by the rotating inner cavity 12 to be transported to any operating hot chamber.

[0043] Optionally, a sample transfer assembly 21 is placed in the rotating inner cavity 12. The sample transfer assembly 21 can extract a material sample from one of the operating hot chambers 11 into the rotating inner cavity 12, and then rotate within the rotating inner cavity 12 to the direction of the first operating hot chamber, thus effectively transferring the material sample. Simultaneously, transfer based on the sample transfer assembly 21 effectively avoids personnel contact with the material sample, reduces the risk of personnel being exposed to radioactive interference, and improves the safety of the personnel's environment.

[0044] Optionally, the sample transfer assembly 21 transfers the material sample to the first operating hot chamber. Outside the first operating hot chamber, the operator manipulates the robotic arm 31 to remove the material sample from the sample transfer assembly 21 and operates the robotic arm 31 to conduct analysis experiments in the first operating hot chamber. Throughout the process, the operator does not come into contact with the material sample, which effectively reduces the risk of radioactive interference to the operator and thus improves the safety of the operator during the work process.

[0045] like Figure 2 As shown, Figure 2 This is a schematic diagram of the sample transfer component 21 in a fan-shaped material sample transfer device according to Embodiment 1 of the present invention. In some preferred embodiments, the sample transfer component 21 includes: a telescopic arm 22 for pushing the material sample from the rotating inner cavity 12 to the first operating hot chamber; and a rotating shaft 23, which is located at the central axis of the rotating inner cavity 12 and connected to the telescopic arm 22, for driving the telescopic arm 22 to rotate between different directions of multiple operating hot chambers 11 until it rotates to the direction facing the first operating hot chamber.

[0046] Based on the above structure, the sample transfer assembly 21 needs to rotate within the rotating inner cavity 12 to move the material sample from its current 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 its current operating hot chamber to the direction corresponding to the first operating hot chamber, thus realizing the rotational transport of the material sample. The rotating shaft 23 is fixed to the center of the rotating inner cavity 12 by anchor bolts. The rotating shaft 23 includes a fixed end and a rotating end. The fixed end is fixedly installed in the rotating inner cavity 12, and the rotating end is movably connected to the fixed end, allowing the rotating end to 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 into the first operating hot chamber, thus transferring the material sample from its current operating hot chamber to the first operating hot chamber. The telescopic arm 22 can be a cylinder, with the cylinder barrel fixedly mounted on the rotating shaft 23. The piston of the cylinder is connected to the material sample, and the piston can extend or retract relative to the cylinder barrel to push the material sample.

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

[0049] Based on the above structure, since the size or shape of the material samples is not uniform, a fixing device is needed when the piston of the cylinder is connected to the material sample, namely, a transfer inner cylinder 24. The transfer inner cylinder 24 is fixedly set at the piston, and the material sample is placed in the transfer inner cylinder 24. During the process of the telescopic arm 22 pushing the transfer inner cylinder 24 to move, the material sample is moved, effectively realizing the effect of transferring the material sample from the current 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 cylindrical, 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 increased interval distance and wasted area, and effectively improving the area utilization rate.

[0051] In some preferred embodiments, the device further includes: an electric shielding door 13, installed on the cavity wall of the rotating inner cavity 12, located at the connection between the plurality of operating hot chambers 11 and the rotating inner cavity 12, for connecting the plurality of operating hot chambers 11 and the rotating inner cavity 12 when the telescopic arm 22 is working; and a processor, connected to the rotating shaft 23, the telescopic arm 22 and the electric shielding door 13, for controlling the rotation angle of the rotating shaft 23, controlling the opening and closing of the telescopic arm 22, and controlling 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 the multiple operating hot chambers 11 and the rotating inner cavity 12 being in a continuous state, which would affect the analytical effect of the experiment in the first operating hot chamber, it is necessary to set up a shielding wall 1 between the multiple operating hot chambers 11 and the rotating inner cavity 12, and at the same time set up 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 pre-set preset angle value, so that the rotating shaft 23 drives the telescopic arm 22 to rotate to the corresponding direction of the first operating hot chamber. Based on the preset angle value, the processor determines the current orientation of the first operating hot chamber and 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, thereby achieving the effect of moving the material sample into the first operating hot chamber.

[0054] Optionally, the staff can control the robotic arm 31 in the first operating hot chamber to pick up the material sample in the transfer inner cylinder 24 and place the material sample on the testing instrument through the robotic arm 31 for simultaneous testing. The staff can complete multiple testing processes without entering the first operating hot chamber, achieving comprehensive analysis of the material sample and effectively reducing the risk of radiation exposure to the staff.

[0055] In some preferred embodiments, it also includes: an operating glove hole 14, which is provided on the shielding wall 1 and connects multiple operating hot chambers 11 with the external environment. Each of the multiple operating hot chambers 11 is provided with an operating glove hole 14. The operating glove hole 14 is used for the robotic arm 31 to enter the multiple operating hot chambers 11 from the external environment.

[0056] Based on the above structure, to allow operators to control the robotic arm 31, it is extended from the first operating hot chamber to the external environment. Operators can control the robotic arm 31 from the external environment, effectively reducing the risk of radiation exposure. An operating glove hole 14 is provided on the shielding wall 1, through which the robotic arm 31 connects the first operating hot chamber to the external environment, effectively enabling operators to complete analysis and testing without entering the first operating hot chamber.

[0057] Optionally, operating glove holes 14 are provided on each of the multiple operating hot chambers 11. A set of robotic arms 31 can be selected. After the original operating hot chamber is used, the robotic arms 31 are taken out through the operating glove holes 14 and placed into the operating glove holes 14 of the first operating hot chamber. This allows the set of robotic arms 31 to be reused, reducing equipment costs. Alternatively, a set of robotic arms 31 can be installed in the glove hole of each operating hot chamber. This method can eliminate the process of moving the robotic arms 31, reduce the workload of the staff, and improve the efficiency of detection and analysis.

[0058] like Figure 3 As shown, Figure 3 This is a schematic diagram of the structure of the robotic arm 31 in a fan-shaped material sample transfer device according to Embodiment 1 of the present invention. In some preferred embodiments, the robotic arm 31 includes: an extension link 32 with a length greater than or equal to a first preset distance, wherein the first preset distance is used to indicate the distance from the operating glove hole 14 to the sample transfer component 21 after the sample transfer component 21 extends into the first operating hot chamber; and a gripping hand 33, installed at the end of the extension link 32 and located in the first operating hot chamber, for gripping the material sample.

[0059] Based on the above mechanism, the extension rod 32 can connect the distance from the operating glove hole 14 to the transfer inner cylinder 24. A movable joint can be provided on the extension rod 32, using a 360-degree rotating electric universal joint, i.e., a ball joint and a socket joint. Using the movable joint allows the extension rod 32 to rotate, making it easier and more precise to contact material samples at multiple angles. Simultaneously, a movable joint is provided at the connection between the gripper 33 and the extension rod 32, allowing the gripper 33 to rotate relative to the extension rod 32, effectively realizing the rotation of the gripper 33 and making it easier and more precise to contact material samples at multiple angles.

[0060] Optionally, based on the function of the extension rod 32, the operator can touch the material sample in the transfer inner cylinder 24 from the external environment. A clamping hand 33 is provided at the end of the extension rod 32. The clamping hand 33 includes a first clamping piece and a second clamping piece, which are symmetrically placed. When the clamping hand 33 touches the material sample, the first clamping piece and the second clamping piece retract simultaneously to clamp the material sample. The operator can operate the extension rod 32 to move the clamping hand 33 away from the transfer inner cylinder 24, effectively realizing the transfer of the material sample in the transfer inner cylinder 24.

[0061] Optionally, both the first and second clamping plates have clamping pads at their ends to hold the material sample. If the material of the clamping hand 33 is too hard, the material sample may break during forceful clamping. The clamping pads, by cushioning the clamping force during clamping, effectively prevent breakage. Furthermore, the indentation created by the clamping pads during clamping effectively holds the material sample in place, preventing it from falling out.

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

[0063] In some preferred embodiments, it also includes: a maintenance shielding door 15, which is disposed on the shielding wall 1 and connects multiple operating hot chambers 11 with the external environment, and a maintenance shielding door 15 is disposed on each of the multiple operating hot chambers 11.

[0064] Based on the above technical solution, during the process of the robotic arm 31 testing the material sample, the material sample may fall, or the robotic arm 31 may be unable to complete the action, requiring the intervention of personnel for analysis and testing. Alternatively, if the testing instrument malfunctions, personnel may need to enter the operating hot chamber for repair. In this case, personnel can enter the operating hot chamber through the maintenance shielding door 15 to complete the task that the robotic arm 31 cannot perform.

[0065] It should be noted that, because the operating hot chamber contains radioactive material samples and instruments that have been exposed to sample radiation for extended periods, these instruments may also be radioactive. Therefore, personnel must wear appropriate protective gear when entering the operating hot chamber 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 type of high-density concrete with a dry apparent density exceeding 2800 kg / m³. 3 It is made by using barite, iron ore, steel scrap, etc. as aggregates, and combining them with strontium cement or barium cement. Heavy concrete has the property of being impermeable 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 low cost, easy processing and molding, and high strength, which can reduce the cost of radiation protection. The higher 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 as the shielding wall 1 can effectively reduce the cost of use and has a good effect on reducing radiation.

[0068] In some preferred embodiments, the electric shielding 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. Lead metal has a high blocking effect, and it is relatively easy to obtain. The cost of using lead metal is lower than that of other metal materials, and the protection level is high, effectively achieving the effect of reducing radiation.

[0070] Example 2

[0071] According to an embodiment of the present invention, a method for transporting fan-shaped material samples is also provided, such as... Figure 4 As shown, Figure 4 This is a flowchart of a fan-shaped material sample transfer method in Embodiment 2 of the present invention.

[0072] Step S11: The material sample is clamped by the robotic arm 31 into the transfer inner cylinder 24;

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

[0074] In 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] In step S14, the electric shielding door 13 corresponding to the first operating hot chamber opens, and the telescopic arm 22 drives the transfer inner cylinder 24 to enter the first operating hot chamber from the rotating inner cavity 12.

[0076] Step S15: The robotic arm 31 in the first operating hot chamber clamps 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 closes.

[0078] Through the above steps S11 to S16, the material sample is moved between multiple operating hot chambers 11 via the sample transfer assembly 21. The staff operates the robotic arm 31 outside the first operating hot chamber to remove the material sample from the sample transfer assembly 21. The staff then operates the robotic arm 31 to conduct analysis experiments in the first operating hot chamber. This achieves the technical effect of reducing the risk of staff being exposed to radioactive interference and improving the safety of staff at work by eliminating the need for staff to come into contact with the material sample. It also solves the technical problem that it is easy to endanger the safety of staff when they are wearing protective clothing and transferring samples between multiple different operating chambers.

[0079] Example 3

[0080] Based on the above embodiments and optional embodiments, the present invention also proposes an optional implementation method. Figure 5 This is a flowchart of an optional fan-shaped material sample transfer method according to Embodiment 3 of the present invention, as shown below. Figure 5 As shown, the method includes:

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

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

[0083] Step S23: By rotating the rotating shaft 23, the inner transfer cylinder 24 is directed in different directions to prepare for entering different operating hot chambers;

[0084] Step S24: Open the electric shielding door 13 and extend the telescopic arm 22 to bring the transfer inner cylinder 24 to the designated position in the first operating hot chamber;

[0085] Step S25: Shorten the telescopic arm 22, close the electric shielding door 13, and complete one material sample transfer process.

[0086] Through steps S21 to S25, 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 merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
