[0047] The features and exemplary embodiments of various aspects of this application will be described in detail below. To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only intended to explain this application and not to limit it. For those skilled in the art, this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples.

[0048] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the process, method, article, or apparatus that includes said element.

[0049] It should be noted that the terms indicating direction, such as first direction X, second direction Y, and third direction Z, used in the application documents are only for the purpose of more clearly illustrating the specific structure of the embodiments of this application in conjunction with the accompanying drawings, and this application is not limited thereto.

[0050] Optionally, the first direction X, the second direction Y, and the third direction Z have included angles between each other.

[0051] Specifically, the third direction Z is parallel to the vertical direction, the first direction X and the second direction Y are both parallel to the horizontal plane, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0052] like Figure 1 and Figure 2 As shown in the embodiment of this application, the radiation source transfer device includes a protective component 1, which includes a protective shell 11 and a protective box 12.

[0053] The protective housing 11 has a through cavity 111 extending along the first direction X; the protective box 12 is detachably inserted into the through cavity 111, and the interior of the protective box 12 has at least one receiving cavity that can accommodate the radiation source.

[0054] When the radiation source is contained in the containment cavity, the protective box 12 can provide the first layer of shielding protection. When the protective box 12 is inserted through the through cavity 111, the protective shell 11 can provide the second layer of shielding protection. Therefore, the protective component 1 formed by the combination of the protective box 12 and the protective shell 11 can effectively improve the shielding effect of the radiation source and reduce the amount of radiation received by the staff during the transportation of the radiation source.

[0055] The principle of radiation shielding is that materials absorb or diffuse ionizing radiation, reducing its energy and thus minimizing harm to the human body or objects. Optionally, both the protective outer shell 11 and the protective box 12 are made of polyethylene material. Polyethylene is a polymer compound formed by the polymerization of ethylene monomers, with carbon and hydrogen elements accounting for approximately 95% of its composition. This compound has a very dense molecular chain structure, giving it excellent radiation-blocking capabilities.

[0056] like Figures 1 to 6 As shown, according to one aspect of an embodiment of this application, limiting members 13 are respectively provided on both sides of the protective shell 11 along the first direction X. When the protective box 12 is inserted into the through cavity 111, both ends of the protective box 12 along the first direction X abut against the limiting members 13. By providing the limiting members 13, the relative position of the protective box 12 and the protective shell 11 along the first direction X can be restricted, preventing the protective box 12 from shifting relative to the protective shell 11 along the first direction X unnecessarily.

[0057] Optionally, the limiting members 13 located at both ends of the protective box 12 along the first direction X can be detachably connected to the protective shell 11, so that the protective box 12 can be disassembled and assembled along the first direction X from the opening at either end of the through cavity 111.

[0058] Optionally, the limiting member 13 located at one end of the protective box 12 along the first direction X is detachably connected to the protective shell 11, and the limiting member 13 located at the other end of the protective box 12 along the first direction X is fixedly connected to the protective shell 11, so that the protective box 12 can only be disassembled and assembled along the first direction X through the opening at one end of the through cavity 111 where the detachably connected limiting member 13 is provided.

[0059] like Figures 1 to 6 As shown, according to one aspect of the embodiments of this application, the protective shell 11 includes two first plates 112 and two second plates 113. The two first plates 112 are arranged opposite each other along the second direction Y, and the two second plates 113 are arranged opposite each other along the third direction Z. The two first plates 112 and the two second plates 113 are alternately connected and enclosed to form a through cavity 111.

[0060] Each first plate 112 is detachably connected to two second plates 113 on both sides along the second direction Y via connectors, and the two first plates 112 and the two second plates 113 are combined to form a rectangular frame structure.

[0061] It should be noted that the dimensions of the first plate 112 along the first direction X and the dimensions of the second plate 113 along the first direction X can be the same or different, and the dimensions of the two second plates 113 along the first direction X can also be the same or different. The dimensions of the two first plates 112 and the two second plates 113 along the first direction X can be designed and determined according to the dimensions of the protective box 12 and the position of the receiving cavity in the protective box 12.

[0062] Along the second direction Y, the projection of the receiving cavity is located at the center of the projection of the first plate 112, and along the third direction Z, the projection of the receiving cavity is located at the center of the projection of the second plate 113. Along the first direction X, the projection of the receiving cavity is located at the center of the projection of the protective box 12. This ensures that after the protective component 1 is assembled, the receiving cavity is located at the center of the protective component 1, thereby ensuring that the radiation source is approximately located at the center of the protective component 1 after being placed in the receiving cavity. This allows the protective component 1 to uniformly shield the radiation source around its periphery, ensuring the shielding effect of the protective component 1 on the radiation source.

[0063] like Figure 1 , Figure 4 and Figure 6 As shown, according to one aspect of an embodiment of this application, with the protective box 12 inserted through the through cavity 111, the two first plates 112 are respectively in contact with the two side surfaces of the protective box 12 along the second direction Y, and the two second plates 113 are respectively in contact with the two side surfaces of the protective box 12 along the third direction Z. This maintains the relative position between the protective member 1 and the protective box 12, while preventing gaps between them from affecting the shielding effect of the protective member 1.

[0064] like Figures 2 to 6 As shown, according to one aspect of the embodiments of this application, one of the two second plates 113 is a top plate 1131, and the other of the two second plates 113 is a bottom plate 1132; the protective box 12 is provided with a roller 121 on the side facing the bottom plate 1132, and the protective box 12 can reciprocate along the first direction X on the bottom plate 1132 by means of the roller 121. By setting the roller 121, the relative movement between the protective box 12 and the protective shell 11 can be rolling, which effectively reduces the friction force during the movement of the protective box 12 relative to the protective shell 11 and ensures the smoothness of the relative movement between the two.

[0065] Optionally, a plurality of lifting rings 1135 are evenly distributed on the surface of the top plate 1131 facing away from the protective box 12, for lifting and moving the protective box 12.

[0066] like Figure 2 , Figure 3 and Figure 5 As shown, according to one aspect of the embodiment of this application, the bottom plate 1132 is provided with a guide strip 114 extending along the first direction X on the side facing the protective box 12. The guide strip 114 is a strip-shaped sheet structure. When the protective box 12 is inserted through the through cavity 111, the roller 121 contacts the guide strip 114. The roughness of the surface of the guide strip 114 that contacts the roller 121 is less than the roughness of the surface of the bottom plate 1132 on the side facing the protective box 12.

[0067] Optionally, the guide bar 114 is a metal guide bar 114 with a smooth surface, thereby effectively reducing the frictional force when the roller 121 moves along it.

[0068] like Figures 1 to 3 , Figure 5 and Figure 6 As shown, according to one aspect of an embodiment of this application, the radiation source transfer device further includes a movable member 2, and a protective member 1 is detachably mounted on the movable member 2. The protective member 1 is used to shield the radiation source from radiation, and the movable member 2 is used to realize the movement and transfer of the protective member 1 and the radiation source.

[0069] like Figures 1 to 3 , Figure 5 and Figure 6 As shown, according to one aspect of the embodiments of this application, the movable component 2 includes a movable vehicle 21 and a mounting frame 22. The mounting frame 22 is detachably mounted on the movable vehicle 21 and is used to connect with the protective component 1.

[0070] Specifically, the base plate 1132 of the protective shell 11 of the protective component 1 is detachably connected to the mounting bracket 22.

[0071] Specifically, the base plate 1132 is recessed with a countersunk hole 1133. The bottom of the countersunk hole 1133 is detachably connected to the mounting bracket 22 via a connector. The connector is a bolt. The bolt passes through the bottom of the countersunk hole 1133 and the mounting bracket 22 and is screwed and fixed with a nut. The bolt head abuts against the bottom of the countersunk hole 1133 on the side surface facing the protective box 12. In this way, the length of the bolt can be effectively shortened while achieving the connection.

[0072] Optionally, the countersunk hole 1133 is provided with a filler 1134 inside, and the surface of the filler 1134 facing the protective box 12 is flush with the surface of the base plate 1132 facing the protective box 12. By filling the countersunk hole 1133 with the filler 1134, the thickness of the base plate 1132 can be basically consistent throughout, thus ensuring the shielding and protection effect of the base plate 1132.

[0073] Optionally, the mobile vehicle 21 is provided with a lever 24 on one side along the first direction X, so that staff can push and pull it to move the mobile vehicle 21.

[0074] like Figures 7 to 8 As shown, according to one aspect of the embodiment of this application, the mounting bracket 22 is provided with a mounting hole, and a flange 221 is detachably connected to the mounting hole. The flange 221 is detachably connected to the bottom of the countersunk hole 1133.

[0075] By setting up flange 221, flange 221 can be replaced separately after it wears out due to stress, without having to replace the entire mounting bracket 22, which can effectively reduce maintenance costs.

[0076] Optionally, such as Figure 9 As shown, according to one aspect of an embodiment of this application, the flange 221 includes a first ring 2211 and a second ring 2212 rotatably connected. The first ring 2211 and the second ring 2212 are coaxially arranged. The first ring 2211 is connected to the mounting bracket 22, and the protective housing 11 is connected to the second ring 2212. This allows the protective member 1 to rotate relative to the mounting bracket 22 around the axis of the flange 221, so that when the radiation source transfer device provided in this embodiment of the application is connected to equipment in subsequent processes, the placement direction of the protective housing 12 can be adjusted, facilitating the use of the protective housing 12 with the equipment in subsequent processes.

[0077] like Figure 8As shown, according to one aspect of the embodiment of this application, a plurality of rotatable balls 222 are provided on the side surface of the mounting bracket 22 facing the protective member 1 at intervals. When the protective member 1 is installed on the mounting bracket 22, the side surface of the protective member 1 facing the mounting bracket 22 contacts each ball 222. When the protective member 1 moves or rotates relative to the mounting bracket 22 along the first direction X and / or the second direction Y, the balls 222 rotate to reduce the friction between the protective member 1 and the mounting bracket 22 and prevent wear between them.

[0078] like Figures 1 to 6 As shown, according to one aspect of the embodiments of this application, the movable component 2 further includes a lifting bracket 23, which is connected between the movable vehicle 21 and the mounting frame 22. The lifting bracket 23 can drive the mounting frame 22 to move the protective box 12 back and forth along the third direction Z to adjust the height of the protective component 1 and the radiation source, and send the radiation source to the required height position.

[0079] like Figures 10 to 15 As shown, according to one aspect of an embodiment of this application, the protective box 12 includes a housing 122, a rotating body 123, and a driving member 124. The housing 122 and the rotating body 123 are used together to shield the radiation source 3, and the rotating body 123 cooperates with the driving member 124 to drive the radiation source 3 to move relative to the housing 122.

[0080] The housing 122 has a rotating cavity inside and a pick-and-place port 1221 on the housing 122. The pick-and-place port 1221 is connected to the rotating cavity and is used to pick up and place the radiation source 3.

[0081] At least a portion of the rotating body 123 is rotatably disposed inside the rotating cavity, and the portion of the rotating body 123 disposed inside the rotating cavity is provided with a recessed receiving groove 1231 for accommodating the radiation source 3.

[0082] The drive component 124 is connected to the rotating body 123, and the drive component 124 can drive the rotating body 123 to move; the drive component 124 can be electrically driven and / or manually driven.

[0083] Optionally, the driving member 124 can drive the rotating body 123 to rotate or drive the rotating body 123 to move in a straight line.

[0084] The housing 122 has an open state and a closed state. In the open state, the receiving slot 1231 is connected to the pick-up and drop-off port 1221. At this time, the radiation source 3 stored in the receiving slot 1231 is directly opposite the pick-up and drop-off port 1221, so that the staff can quickly pick up and drop the radiation source 3, shortening the overall time spent in the process of picking up and dropping the radiation source 3, thereby effectively reducing the amount of radiation received by the staff during the process of picking up and dropping the radiation source 3. In the closed state, the receiving slot 1231 and the pick-up and drop-off port 1221 are staggered, and the receiving slot 1231 is closed by the housing 122, so that the radiation source 3 is located in a sealed space to ensure the shielding effect of the housing 122 on the radiation source 3.

[0085] like Figure 10 and Figure 11 As shown, according to one aspect of the embodiments of this application, there are multiple pick-up and put-out ports 1221, and the multiple pick-up and put-out ports 1221 are spaced apart along the first direction X and / or the second direction Y; there are multiple receiving slots 1231, and the multiple receiving slots 1231 are spaced apart; in the open state, each receiving slot 1231 is connected to a corresponding pick-up and put-out port 1221.

[0086] Optionally, the loading / unloading port 1221 and the receiving slot 1231 are all concentrated in the middle position along the first direction X, the second direction Y and the third direction Z, so as to ensure the shielding effect of the shell 122 on the radiation source 3.

[0087] Optionally, the shell 122 is made of polyethylene and the rotating body 123 is made of graphite. Both polyethylene and graphite have good shielding effects, which can effectively ensure the shielding effect of the shielding device of the radiation source provided in this embodiment on the radiation source 3.

[0088] like Figure 13 and Figure 14 As shown, according to one aspect of an embodiment of this application, the housing 122 includes a first housing 1222 and a second housing 1223 joined together along a third direction Z. The first housing 1222 has a first recessed groove on the side facing the second housing 1223, and a pick-and-place port 1221 is formed in the first housing 1222, communicating with the first recessed groove. The second housing 1223 has a second recessed groove on the side facing the first housing 1222, and the first recessed groove and the second recessed groove communicate to form a rotary cavity. By configuring the housing 122 into two parts, the first housing 1222 and the second housing 1223, the housing 122 has the advantage of being easy to process and assemble.

[0089] Optionally, such as Figure 10 and Figure 12As shown, according to one aspect of the embodiments of this application, a first groove extends along the first direction X and penetrates both end faces of the first housing 1222 along the first direction X, and a second groove extends along the first direction X and penetrates both end faces of the second housing 1223 along the first direction X. The first housing 1222 and the second housing 1223 are connected and enclosed to form a cylindrical structure that penetrates along the first direction X. Setting the first groove and the second groove as through grooves can further simplify the structure of the first housing 1222 and the second housing 1223, making the first housing 1222 and the second housing 1223 easier to process.

[0090] The housing 122 also includes two end plates 1224, which are detachably connected to both ends of the cylindrical structure along the first direction X. The end plates 1224 and the cylindrical structure enclose a sealed rotating cavity to ensure the shielding effect of the housing 122.

[0091] Optionally, such as Figure 10 and Figure 12 As shown, the second housing 1223 has multiple rollers 121 on the side opposite to the first housing 1222 to facilitate the movement of the protective box 12.

[0092] Optionally, such as Figure 13 and Figure 14 As shown, according to one aspect of an embodiment of this application, both the first groove and the second groove are arc-shaped grooves, the rotating cavity is a cylindrical cavity, and the rotating body 123 has a cylindrical structure. When the rotating body 123 is inserted into the interior of the rotating cavity, the outer surface of the rotating body 123 is in contact with the inner surface of the rotating cavity. In this embodiment, the driving member 124 drives the rotating body 123 to rotate, thereby adjusting the relative position of the radiation source 3 and the housing 122.

[0093] like Figure 13 and Figure 14 As shown, according to one aspect of an embodiment of this application, there is a first distance between the bottom of the first groove and the side surface of the first housing 1222 facing away from the second housing 1223, and a second distance between the bottom of the second groove and the side surface of the second housing 1223 facing away from the first housing 1222, wherein the first distance is less than the second distance. This ensures that in the open state, the distance between the receiving groove 1231 and the radiation source 3 installed inside it and the side surface of the first housing 1222 facing away from the second housing 1223 is minimized, facilitating the handling of the radiation source 3 by personnel; and in the closed state, it ensures that there is sufficient distance between the receiving groove 1231 and the radiation source 3 installed inside it and the side surface of the second housing 1223 facing away from the first housing 1222 to shield the radiation source 3.

[0094] like Figure 15As shown, according to one aspect of the embodiment of this application, the receiving groove 1231 is provided with a clamp 125 inside, the clamp 125 is detachably connected to the bottom of the receiving groove 1231 so as to facilitate the replacement of the clamp 125 separately; the clamp 125 can hold and fix the radiation source 3.

[0095] The radiation source transfer device provided in this application embodiment includes a protective box and a protective shell. The protective box and the protective shell provide two layers of shielding protection for the radiation source, effectively shielding the radiation generated by the radiation source. It has a good radiation isolation effect and can effectively reduce the amount of radiation received by the staff during the transfer of the radiation source.

[0096] like Figure 16 As shown in the figure, this application embodiment also provides a detection device, which includes an analyzer 100 and a radiation source transfer device as described above.
