Detailed implementation manners

[0037] The following further describes in detail the implementation manners of the present application with reference to the drawings and embodiments. The detailed description and drawings of the following embodiments are used to exemplarily illustrate the principle of the present application, but cannot be used to limit the scope of the present application. The present application can be implemented in many different forms, not limited to the specific embodiments disclosed in the text, but including all technical solutions falling within the scope of the claims.

[0038] An X-ray detection device that uses X-rays for imaging (e.g., an X-ray security inspection machine) can detect items using the penetrability of X-rays and is widely used in places that require security inspections, such as railway stations, airports, and hospitals.

[0039] In related technologies, most X-ray security inspection machines adopt an overall frame design. The frame formed by welding and the outer shell arranged on the frame constitute the main structure of the X-ray security inspection machine. Related components such as the X-ray generator, X-ray detector, image processing system, and control system of the X-ray security inspection machine can be installed at corresponding positions of the main structure.

[0040] Since the welded frame is prone to deformation and has a large error, it is more difficult to assemble subsequent other components with the frame body.

[0041] To solve the above problems, the present application provides an X-ray detection system and a security inspection device. The following will be combined with Figures 1 to 15 to describe the X-ray detection system and the security inspection device provided by the embodiments of the present application.

[0042] It should be understood that there can be multiple implementation manners of the present application and should not be construed as being limited to the embodiments described herein. The embodiments described herein are only for a more thorough and clear understanding of the present application.

[0043] Exemplary X-ray detection system Reference Figures 1 to 3 In a first aspect, an embodiment of the present application provides an X-ray detection system 1000. The X-ray detection system 1000 includes an X-ray detection unit 10. The X-ray detection unit 10 includes a first box body part 11, a second box body part 12, and a third box body part 13. The first end of the second box body part 12 is detachably connected to the first box body part 11, and the second end of the second box body part 12 is detachably connected to the third box body part 13 to form the main structure of the X-ray detection unit 10. The main structure has a first channel 102, and shielding curtains 27 (e.g., lead curtains) can be arranged at both ends of the first channel 102. The X-ray detection unit 10 can detect items passing through the first channel 102.

[0044] In this way, the main structure of the X-ray detection unit 10 is formed by detachably splicing the first box body part 11, the second box body part 12, and the third box body part 13. Each part can be transported separately and then assembled. The volume of each part is relatively small, which is convenient for assembly, transportation, and maintenance, and can reduce transportation and packaging costs. Moreover, to a certain extent, the risk of damage caused by easy extrusion or collision due to a large volume can be avoided. At the same time, there is no need to set up a separate frame, which reduces the number of parts and production costs. Then, the modular box design is conducive to automated production and batch production, improving production efficiency and reducing production costs.

[0045] Generally, due to the large volume and heavy weight of the X-ray detection system 1000, under the action of the self-gravity of the second box body part 12, the splicing joints between the second box body part 12, the first box body part 11 and the third box body part 13 can be as close as possible, and since the plates at the splicing joints are relatively thick, X-rays are not easily leaked from the splicing joints. Therefore, there is often no need to additionally consider the problem of X-ray leakage.

[0046] However, the installation of the X-ray detection system 1000 needs to consider the installation positioning problem, and in the case where the volume of the X-ray detection system 1000 is small, the problem of X-ray leakage also needs to be considered. For this purpose, a first platform 112 may be formed at the first end (for example, the top end) of the first box body part 11, a second platform 132 may be formed at the first end (for example, the top end) of the third box body part 13, the first end of the second box body part 12 is detachably connected to the first platform 112, and the second end of the second box body part 12 is detachably connected to the second platform 132.

[0047] In this way, during installation, the bottom surfaces of the two ends of the second box body part 12 are respectively abutted against and then connected to the first platform 112 and the second platform 132, which can reduce and avoid X-ray leakage at the joints.

[0048] The first platform 112 may be provided with a first step (not shown in the figure), and the second platform 132 may be provided with a second step (not shown in the figure). The side surface of the first end of the second box body part 12 may be abutted against the first step, and the side surface of the second end of the second box body part 12 may be abutted against the second step.

[0049] Exemplarily, the side surfaces of the two ends of the second box body part 12 are respectively abutted against the first step and the second step, and after the bottom surfaces of the two ends of the second box body part 12 are respectively abutted against the first platform 112 and the second platform 132, they are connected to the first box body part 11 and the second box body part 12 by at least one of screwing (such as screws or bolt nuts), locking and pinning.

[0050] In this way, during installation, the first step can block the splicing joint between the first box body part 11 and the second box body part 12, further avoiding X-ray leakage from the splicing joint. The second step can block the splicing joint between the second box body part 12 and the third box body part 13, further avoiding X-ray leakage from the splicing joint. Thus, the safety of the X-ray detection system 1000 is improved. In addition, the first step and the second step can also play a guiding and limiting role during installation, facilitating the installation.

[0051] In an alternative example, the first platform 112 may be provided with a first groove (not shown in the figure), the first end of the second box body portion 12 may be provided with a first protrusion (not shown in the figure), and the first protrusion is snap-fitted in the first groove. The second platform 132 may be provided with a second groove (not shown in the figure), the second end of the second box body portion 12 may be provided with a second protrusion (not shown in the figure), and the second protrusion is snap-fitted in the second groove.

[0052] In this way, during installation, through the cooperation of the first groove provided on the first platform 112 and the first protrusion provided at the first end (for example, the bottom of the first end) of the second box body portion 12, the splicing joint between the first box body portion 11 and the second box body portion 12 can be blocked, further preventing X-rays from leaking from the splicing joint. Through the cooperation of the second groove provided on the second platform 132 and the second protrusion provided at the second end (for example, the bottom of the second end) of the second box body portion 12, the splicing joint between the second box body portion 12 and the third box body portion 13 can be blocked, further preventing X-rays from leaking from the splicing joint. Thus, the safety of the X-ray detection system 1000 is improved.

[0053] In addition, the first groove and the second groove can also play a guiding and limiting role during installation, facilitating installation.

[0054] Exemplarily, after the two ends of the second box body portion 12 are respectively snap-fitted with the first box body portion 11 and the third box body portion 13 through protrusions, it can be connected to the first box body portion 11 and the second box body portion 12 by at least one of screwing (such as screws or bolt nuts), locking, and pinning.

[0055] It can be understood that the anti-X-ray leakage setting at the splicing joint between the first box body portion 11 and the third box body portion 13 and the second box body portion 12 can also be achieved by setting a step at one splicing position and setting a groove and a protrusion at the other splicing position.

[0056] Reference Figure 3 and Figure 4 , the first box body portion 11 may include a first box body main body 111 and a first cover (not shown in the figure), and the first cover covers the first box body main body 111. For example, the first box body main body 111 may be formed by bending a metal plate.

[0057] Optionally, a lead plate is attached (such as by bonding, riveting, or spot welding, etc.) to the first box body main body 111 and / or the first cover to prevent X-ray leakage. For example, a lead plate is attached to the first box body main body 111.

[0058] Exemplarily, the first box body main body 111 and the first cover can be screwed together. For example, they can be connected together by screws or bolts and nuts, which is convenient for maintenance. Moreover, the first cover also adopts a leak-proof design to further improve the safety of the equipment.

[0059] Exemplarily, the X-ray detection system 1000 further includes an image acquisition module 14, and the image acquisition module 14 can be arranged inside the first box body main body 111, which is convenient for integrated design.

[0060] Exemplarily, the image acquisition module 14 includes an acquisition board that receives the analog signal output by the X-ray detector and performs preliminary processing, and a data processing board that further processes and transmits the acquired digital signal. Other structures of the image acquisition module 14 can refer to the conventional settings in the art and will not be elaborated here.

[0061] In this way, the image acquisition module 14 can be integrated in the first box body part 11, with a compact structure. Moreover, the influence of dust, etc. on the performance of the image acquisition module 14 can be avoided.

[0062] Reference Figure 6 , the second box body part 12 can include a second box body main body 121 and a second cover (not shown in the figure), and the second cover covers the second box body main body 121. For example, the second box body main body 121 can be formed by bending a metal plate.

[0063] Exemplarily, the second box body main body 121 and the second cover can be screwed together, for example, by screws or bolts and nuts, which is convenient for maintenance and inspection.

[0064] Optionally, a lead plate is pasted on the second box body main body 121 and / or the second cover to prevent X-ray leakage. For example, a lead plate is pasted (such as bonded, riveted or spot welded, etc.) on the second box body main body 121.

[0065] Exemplarily, the X-ray detection system 1000 further includes an X-ray emitter, a light source collimating device 15 and an industrial control module 16. The X-ray emitter, the light source collimating device 15 and the industrial control module 16 are arranged in the second box body main body 121 to facilitate integrated design.

[0066] Exemplarily, the industrial control module 16 can include an industrial computer, a control module (i.e., the interface between the industrial computer and external devices), a communication interface, etc. Other structures of the industrial control module 16 can refer to the conventional settings in the art and will not be elaborated here.

[0067] In this way, the X-ray emitter, the light source collimating device 15 and the industrial control module 16, etc. can be integrated in the second box body part 12, with a compact structure. Moreover, the influence of dust, etc. on the performance of these components can be avoided.

[0068] Reference Figure 5 Figure 5 , the third box body part 13 may include a third box body main body 131 and a third cover body (not shown in the figure), and the third cover body covers the third box body main body 131. For example, the third box body main body 131 may be formed by bending a metal plate. Exemplarily, the X-ray detection system 1000 may further include a power distribution board 17 and a transformer 18, and the power distribution board 17 and the transformer 18 are disposed in the third box body main body 131 (for example, the power distribution board 17 and the transformer 18 are respectively fixed in the third box body main body 131 by screws or bolts and nuts), so as to facilitate the integrated design.

[0069] Optionally, a lead plate is attached to the third box body main body 131 and / or the third cover body to prevent X-ray leakage. For example, a lead plate is attached (such as bonded, riveted or spot welded, etc.) to the third box body main body 131.

[0070] Exemplarily, the third box body main body 131 and the third cover body may be screwed together, for example, connected together by screws or bolts and nuts, which is convenient for disassembly, maintenance, inspection and transportation.

[0071] In this way, components such as the power distribution board 17 and the transformer 18 can be integrated in the second box body part 12, and the structure is compact. Moreover, the influence of dust and the like on the performance of these components can be avoided.

[0072] In one example, it can be satisfied simultaneously: the first box body part 11 includes a first box body main body 111 and a first cover body, the X-ray detection system 1000 further includes an image acquisition module 14, the image acquisition module 14 is disposed in the first box body main body 111, and the first cover body covers the first box body main body 111. The second box body part 12 includes a second box body main body 121 and a second cover body, the X-ray detection system 1000 further includes an X-ray emitter, a light source collimating device 15 and an industrial control module 16, the X-ray emitter (not shown in the figure), the light source collimating device 15 and the industrial control module 16 are disposed in the second box body main body 121, and the second cover body covers the second box body main body 121. The third box body part 13 includes a third box body main body 131 and a third cover body, the X-ray detection system 1000 further includes a power distribution board 17 and a transformer 18, the power distribution board 17 and the transformer 18 are disposed in the third box body main body 131, and the third cover body covers the second box body main body 121.

[0073] In this way, it is beneficial to the overall integrated design of the X-ray detection system 1000, and the structure is compact.

[0074] Return to reference Figure 2 and Figure 3, the X-ray detection system 1000 may further include an X-ray detector assembly 101. The X-ray detector assembly 101 may include an X-ray detector (not shown in the figure) and a mounting base (not shown in the figure). Both ends of the mounting base can be detachably connected to the first box body and the third box body (for example, connected by bolts and nuts), and the X-ray detector is disposed on the base. A shielding plate (not shown in the figure) is provided on the base, an X-ray passing slit (not shown in the figure) is provided between the shielding plates, and a protection plate (not shown in the figure) is provided on the X-ray passing slit. The protection plate can transmit X-rays and can be made of a material with an equivalent atomic number less than or equal to 18. For example, the protection plate can be made of an acrylic plate or aluminum material, etc.

[0075] In this way, the X-ray detector can receive X-rays through the X-ray passing slit, and then the article can be detected. Moreover, the protection plate provided on the passing slit can prevent dust and the like from falling into the X-ray detector 101 and affecting the detection result.

[0076] Reference Figure 3 , a first telescopic leg 19 may be provided at the bottom of the X-ray detection unit 10 to adjust the height of the X-ray detection unit 10 according to the needs of a specific application scenario. For example, at least one first telescopic leg 19 may be provided at the bottom of the first box body portion 11, and at least one first telescopic leg 19 may be provided at the bottom of the third box body portion 13. In one example, one first telescopic leg 19 may be respectively provided at both ends of the bottom of the first box body portion 11, and one first telescopic leg 19 may be respectively provided at both ends of the bottom of the third box body portion 13, and the height can be adjusted as needed while making the force more uniform.

[0077] It can be understood that other numbers of first telescopic legs 19, such as 1, 3, or 4, etc., may also be provided at the bottom of the first box body portion 11 and the bottom of the third box body portion 13 respectively according to the needs of a specific application scenario.

[0078] Here, the specific structure of the first telescopic leg 19 can refer to the conventional settings in the art and will not be elaborated here.

[0079] Reference Figure 1 , Figure 2 and Figure 8 , the X-ray detection system 1000 may further include at least one expansion unit 20. The at least one expansion unit 20 may include a first side plate 21, a second side plate 22, and a top plate 23. Both ends of the top plate 23 can be detachably connected to the first side plate 21 and the second side plate 22 respectively. The expansion unit 20 has an expansion channel. One side of the expansion channel is detachably connected to the X-ray detection unit 10, and a shielding curtain 27 is provided on the other side of the expansion channel.

[0080] In this way, the item to be detected can be buffered by the extension unit 20. Moreover, the extension unit 20 is formed by detachably connecting the first side plate 21, the second side plate 22 and the top plate 23 (for example, by bolt and nut or screw connection), which is convenient for handling and maintenance.

[0081] Exemplarily, the first side plate 21 and the second side plate 22 are respectively formed by sequentially stacking and connecting a panel and a cover plate. For example, they can be formed by sequentially stacking and fixing the panel and the cover plate to each other (such as bonding, riveting or spot welding, etc.). Optionally, the first side plate 21 and the second side plate 22 further include lead plates. For example, the first side plate 21 can be formed by riveting the first panel 211, the first lead plate 212 and the first cover plate 213 in sequence, and the second side plate 22 can be formed by riveting the second panel 221, the lead plate and the cover plate in sequence. At least at the first ends of the first side plate 21 and the second side plate 22, the cover plate extends beyond the panel and / or the lead plate to avoid X-ray leakage at the joint, and the top plate 23 can be snapped between the first side plate 21 and the second side plate 22 to avoid errors and improve the installation accuracy.

[0082] Generally, since the extension unit 20 is large in volume and heavy in mass, under the action of the self-gravity of the top plate 23, the splicing joints between the top plate 23, the first side plate 21 and the second side plate 22 can be as close as possible, and since the plates at the splicing joints are relatively thick, X-rays are not easily leaked from the splicing joints. Therefore, generally, there is no need to additionally consider the problem of X-ray leakage.

[0083] However, the installation of the extension unit 20 needs to consider the positioning problem, and when considering the case where the extension unit 20 is small in volume, the problem of X-ray leakage also needs to be considered. Exemplarily, referring to Figure 11 , at the first ends of the first side plate 21 and the second side plate 22, the cover plate is folded and extended to form a third step 26 to support and limit the top plate 23.

[0084] Exemplarily, the top plate 23 can include a top plate housing 231 and a door plate 232. The door plate 232 can be covered on the top plate housing 231, and the top plate housing 231 and / or the door plate 232 can be attached with lead plates to prevent X-ray leakage. For example, the top plate housing 231 can be formed by bending a metal plate. Optionally, a lead plate is attached (such as bonding, riveting or spot welding, etc.) to the top plate housing 231.

[0085] Referring to Figure 8 , a reinforcing rib 233 can be provided on the side of the top plate housing 231 away from the X-ray detection unit 10, and the shielding curtain 27 can be detachably arranged on the reinforcing rib 233. For example, it can be connected to the reinforcing rib 233 by screws or bolt and nut.
