Description

Technical Field

[0001] The present application belongs to the technical field of security equipment design, and specifically relates to a security inspection equipment. Background Art

[0002] During the process of security inspection equipment detecting items, when the inspected item enters the security inspection channel, the radiation beam passes through the inspected item and hits the detector. Because items of different materials and thicknesses absorb radiation to different degrees, the detector converts the radiation containing the item information into visible light, and then converts it into electrical signals, which are processed by the processor into images.

[0003] At present, a security inspection channel of a security inspection device is usually provided with a radiation source and a detector assembly, wherein the radiation source is arranged in the security inspection device along the width direction of the security inspection channel to perform security monitoring on the items in the security inspection channel. However, when the security inspection device is provided with two or more security inspection channels, each radiation source will occupy a larger space in the width direction of the security inspection device after adopting the above arrangement, thereby resulting in a larger size of the entire security inspection device. Summary of the invention

[0004] The purpose of the embodiments of the present application is to provide a security inspection device that can solve the problem of large size of current security inspection devices.

[0005] In order to solve the above technical problems, this application is implemented as follows: The embodiment of the present application provides a security inspection device, including a first security inspection device and a second security inspection device connected to each other. The first security inspection device and the second security inspection device each include a device body, a first radiation source and a first detector assembly. The device body is provided with a security inspection passage and a first avoidance opening connected to the security inspection passage. The first radiation source and the first detector assembly are both arranged in the device body. The first radiation source of the first security inspection device and the first radiation source of the second security inspection device are both located in the accommodation space between the device body of the first security inspection device and the device body of the second security inspection device, and the two are arranged at intervals in the passing direction of the security inspection passage. The first radiation source is opposite to the first detector assembly through the first avoidance opening, and the first detector assembly is used to receive radiation emitted by the first radiation source.

[0006] Compared with the security inspection equipment with a dual-channel structure in the prior art, the first ray source of the first security inspection device and the first ray source of the second security inspection device in the present application are both arranged in the accommodation space between the device body of the first security inspection device and the device body of the second security inspection device, that is, the first ray source of each security inspection device is arranged on the outer surface of the device body, and the first ray source of the first security inspection device and the first ray source of the second security inspection device are arranged at intervals in the passing direction of the security inspection channel, so that the two first ray sources corresponding to the adjacent security inspection channels only need to occupy the space occupied by one first ray source in the width direction of the security inspection device, thereby reducing the width of the security inspection device, and then reducing the size of the security inspection device. Therefore, the embodiment of the present application can solve the problem of the large size of the current security inspection equipment.

[0007] In addition, when the first radiation source is located between the main body of the first security inspection device and the main body of the second security inspection device, the security inspection channel of the first security inspection device and the security inspection channel of the second security inspection device are closer to passers-by, making it easier for passers-by to place items in the security inspection channel.

DETAILED DESCRIPTION

[0010] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0011] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0012] The security inspection equipment provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0013] like Figures 1 to 11 As shown, the embodiment of the present application discloses a security inspection device, which includes a first security inspection device 100 and a second security inspection device 200 connected to each other. The first security inspection device 100 and the second security inspection device 200 can both independently perform security inspection on a package.

[0014] The first security inspection device 100 and the second security inspection device 200 both include a device body 110, a first radiation source 120, and a first detector assembly 130. Optionally, the first radiation source 120 can be used to emit X-rays, and of course, can also emit other types of radiation, which is not specifically limited in the present embodiment of the application. The device body 110 is provided with a security inspection channel and a first avoidance opening 112 connected to the security inspection channel. The inspected article enters the security inspection channel from the entrance of the security inspection channel, and moves from the exit of the security inspection channel to the outside of the security inspection channel after being scanned and detected by radiation in the security inspection channel. The first ray source 120 and the first detector assembly 130 are both arranged in the device body 110. The first ray source 120 of the first security inspection device 100 and the first ray source 120 of the second security inspection device 200 are both located in the accommodating space between the device body 110 of the first security inspection device 100 and the device body 110 of the second security inspection device 200, and the two are arranged at intervals in the passing direction of the security inspection channel. The first ray source 120 is opposite to the first detector assembly 130 through the first avoidance opening 112, and the first detector assembly 130 is used to receive rays emitted by the first ray source 120.

[0015] Compared with the security inspection equipment with a dual-channel structure in the prior art, the first ray source 120 of the first security inspection device 100 and the first ray source 120 of the second security inspection device 200 in the present application are both arranged in the accommodation space between the device body 110 of the first security inspection device 100 and the device body 110 of the second security inspection device 200, that is, the first ray source 120 of each security inspection device is arranged on the outer surface of the device body 110, and the first ray source 120 of the first security inspection device 100 and the first ray source 120 of the second security inspection device 200 are arranged at intervals in the passing direction of the security inspection channel, so that the two first ray sources 120 corresponding to the adjacent security inspection channels only need to occupy the space occupied by one first ray source 120 in the width direction of the security inspection device, thereby reducing the width of the security inspection device, and further reducing the size of the security inspection device. Therefore, the embodiment of the present application can solve the problem of the large size of the current security inspection device.

[0016] In addition, when the first radiation source 120 is located between the device body 110 of the first security inspection device 100 and the device body 110 of the second security inspection device 200, the security inspection channel of the first security inspection device 100 and the security inspection channel of the second security inspection device 200 are closer to passers-by, making it convenient for passers-by to place items in the security inspection channel.

[0017] In an optional embodiment, in the passing direction of the security inspection channel, one of the first radiation source 120 of the first security inspection device 100 and the first radiation source 120 of the second security inspection device 200 is located at the first end of the accommodation space between the device body 110 of the first security inspection device 100 and the device body 110 of the second security inspection device 200, and the other is located at the second end of the accommodation space, that is, the first radiation source 120 of the first security inspection device 100 and the first radiation source 120 of the second security inspection device 200 are respectively close to the two ends of the security inspection channel. When any one of the first radiation source 120 of the first security inspection device 100 and the first radiation source 120 of the second security inspection device 200 fails, it can be directly repaired without disassembling the first security inspection device 100 or the second security inspection device 200, which can save time and effort. Of course, the first radiation source 120 of the first security inspection device 100 and the first radiation source 120 of the second security inspection device 200 can both be set in the middle part of the accommodation space.

[0018] Optionally, when the traveling direction of the security inspection channel of the first security inspection device 100 is the same as the traveling direction of the security inspection channel of the second security inspection device 200, one of the first ray source 120 of the first security inspection device 100 and the first ray source 120 of the second security inspection device 200 is arranged close to the entrance of the security inspection channel, and the other is arranged close to the exit of the security inspection channel; when the traveling direction of the security inspection channel of the first security inspection device 100 is opposite to the traveling direction of the security inspection channel of the second security inspection device 200, the first ray source 120 of the first security inspection device 100 and the first ray source 120 of the second security inspection device 200 can both be arranged close to the entrance or exit of the security inspection channel.

[0019] Optionally, in any of the above embodiments, the device body 110 of the first security inspection device 100 and the device body 110 of the second security inspection device 200 can be connected by plugging or hanging through a protruding structure; or, the security inspection device also includes a connecting component 300 connected between the device body 110 of the first security inspection device 100 and the device body 110 of the second security inspection device 200, and the connecting component 300 can be a connecting plate, which can be arranged between the first ray source 120 of the first security inspection device 100 and the first ray source 120 of the second security inspection device 200; or, in other optional embodiments, the connecting component 300 includes a first protective structure 310 and a second protective structure 320, and optionally, at least one of the first protective structure 310 and the second protective structure 320 can be a protective door, or a protective curtain (for example, it can be formed of the same material as the lead curtain of the security inspection machine), or a protective plate, or a combination of any two of the protective door, the protective curtain and the protective plate, and the embodiment of the present application does not impose specific restrictions on this. The specific implementation form of the protective structure can be reasonably determined according to the specific use of the security inspection equipment. For example, if the protective structure is implemented in the form of a protective door, it can be further implemented in an up-and-down opening and closing manner or a left-and-right opening and closing manner; for example, if the protective structure is implemented in the form of a protective curtain, the protective curtain can be specifically in the form of a single-layer lead curtain or a multi-layer lead curtain; for example, if the protective structure is implemented in the form of a protective plate, the protective plate can be installed at the end of the accommodation space between the device bodies of the first security inspection device and the second security inspection device in a detachable connection manner. The first protective structure 310 and the second protective structure 320 can protect the radiation source, and on the other hand, can also maintain the integrity of the overall structure of the security inspection equipment.

[0020] In the passing direction of the security inspection channel, the first radiation source 120 is located between the first protective structure 310 and the second protective structure 320. Optionally, the first protective structure 310 can be opposite to the first radiation source 120 of the first security inspection device 100, and the second protective structure 320 can be opposite to the first radiation source 120 of the second security inspection device 200. Of course, the first protective structure 310 can also be opposite to the first radiation source 120 of the second security inspection device 200, and the second protective structure 320 can also be opposite to the first radiation source 120 of the first security inspection device 100. Both the first protective structure 310 and the second protective structure 320 have an open state and a closed state. When at least one of the first protective structure 310 and the second protective structure 320 is in the open state, the first radiation source 120 is exposed in the direction of travel of the security inspection channel, thereby facilitating maintenance or adjustment of the leaked radiation source; when both the first protective structure 310 and the second protective structure 320 are in the closed state, the first protective structure 310 and the second protective structure 320 are used to shield the first radiation source 120 in the direction of travel of the security inspection channel.

[0021] Exemplarily, when any one of the first radiation source 120 of the first security inspection device 100 and the first radiation source 120 of the second security inspection device 200 fails, the corresponding protective structure, i.e., the first protective structure 310 or the second protective structure 320, can be opened to repair the first radiation source 120 of the first security inspection device 100 or the first radiation source 120 of the second security inspection device 200; when the first radiation source 120 is in a working state, the first protective structure 310 and the second protective structure 320 are both in a closed state, which can prevent the first radiation source 120 of the first security inspection device 100 and the first radiation source 120 of the second security inspection device 200 from being collided with objects in the external environment, thereby playing a protective role; and when the first protective structure 310 and the second protective structure 320 are both in a closed state, the setting of the first protective structure 310 and the second protective structure 320 can shield the first radiation source 120 and other structures set in the accommodating space, thereby improving the aesthetics of the security inspection equipment.

[0022] In a further optional embodiment, one of the device body 110 of the first security inspection device 100 and the device body 110 of the second security inspection device 200 is movably connected to the first end of the first protective structure 310, and the other is detachably connected to the second end of the first protective structure 310. For example, the first protective structure 310 can be a door-type structure so that the first protective structure 310 can be switched between an open state and a closed state. When the first radiation source 120 disposed near the first protective structure 310 needs to be repaired, the end of the first protective structure 310 detachably connected to one device body is disassembled, while the other end of the first protective structure 310 is still connected to the other device body. The first protective structure 310 is rotated to be in an open state, thereby exposing the first radiation source 120 to facilitate its repair.

[0023] In the embodiments of the present application, the present application does not make any specific limitations on the specific implementation of the active connection between different components / parts, which can be reasonably determined based on specific usage conditions. For example, the active connection can be implemented by means of a hinge or a rotation connection.

[0024] And / or, in other optional embodiments, one of the device body 110 of the first security inspection device 100 and the device body 110 of the second security inspection device 200 is movably connected to the first end of the second protective structure 320, and the other is detachably connected to the second end of the second protective structure 320, that is, the second protective structure 320 can be a door-type structure, so that the second protective structure 320 can be switched between an open state and a closed state. When the first radiation source 120 arranged near the second protective structure 320 needs to be repaired, the end of the second protective structure 320 detachably connected to one device body is disassembled, while the other end of the second protective structure 320 is still connected to the other device body, and the second protective structure 320 is rotated to be in an open state, so that the first radiation source 120 is exposed to facilitate its maintenance.

[0025] In the above scheme, the first protective structure 310 and the second protective structure 320 can both be connected to the first security inspection device 100 and the second security inspection device 200 using a door structure, which can shorten the time for opening the first protective structure 310 and the second protective structure 320, thereby improving the maintenance work efficiency.

[0026] In another optional embodiment, the first protective structure 310 is detachably connected to the device body 110 of the first security inspection device 100 and the device body 110 of the second security inspection device 200, so that the first protective structure 310 can be switched between an open state and a closed state. When the first radiation source 120 arranged near the first protective structure 310 needs to be repaired, the two ends of the first protective structure 310 are respectively separated from the device bodies 110 of the first security inspection device 100 and the second security inspection device 200, and the first protective structure 310 is removed, so that the first radiation source 120 is exposed to facilitate its repair.

[0027] And / or, in other optional embodiments, the second protective structure 320 is detachably connected to the device body 110 of the first security inspection device 100 and the device body 110 of the second security inspection device 200, so that the second protective structure 320 can be switched between an open state and a closed state. When the first radiation source 120 arranged near the second protective structure 320 needs to be repaired, the two ends of the second protective structure 320 are separated from the device bodies 110 of the first security inspection device 100 and the second security inspection device 200, respectively, and the first protective structure 310 is removed, so that the first radiation source 120 is exposed to facilitate its repair.

[0028] In the above scheme, when the first radiation source 120 needs to be repaired, the first protective structure 310 and the second protective structure 320 are removed from the device body 110 of the first security inspection device 100 and the second security inspection device 200, so as to avoid interference to the staff and facilitate the first security inspection device 100 and the second security inspection device 200 to be used separately.

[0029] In another optional embodiment, the connection assembly 300 further includes at least one of a bottom plate 330 and a top plate, that is, only the bottom plate 330 may be provided, only the top plate may be provided, or both the bottom plate 330 and the top plate may be provided. The bottom plate 330 is provided below the first radiation source 120, and the top plate is provided above the first radiation source 120. The bottom plate 330 and the top plate are connected between the device body 110 of the first security inspection device 100 and the device body 110 of the second security inspection device 200. In this case, the connection area between the device body 110 of the first security inspection device 100 and the device body 110 of the second security inspection device 200 may be increased, thereby improving the connection stability and firmness between the first security inspection device 100 and the second security inspection device 200; and the provision of the bottom plate 330 and the top plate may prevent impurities in the environment from contacting the first radiation source 120, thereby protecting the first radiation source 120. It should be noted that when the connecting component 300 also includes at least one of the bottom plate 330 and the top plate, in the direction of travel of the security inspection channel, the length of the bottom plate 330 and the top plate can be equal to the distance between the first protective structure 310 and the second protective structure 320, thereby improving the performance of the connecting component 300 in protecting the first radiation source 120; further, when the connecting component 300 includes both the bottom plate 330 and the top plate, the first protective structure 310, the second protective structure 320, the bottom plate 330, the top plate, the device body 110 of the first security inspection device 100 and the device body 110 of the second security inspection device 200 can together form a closed accommodation space to prevent impurities in the external environment from entering the closed accommodation space.

[0030] In a further optional embodiment, the connecting assembly 300 also includes a bottom plate 330 and a top plate. Optionally, one of the bottom plate 330 and the top plate is movably connected to the third end of the first protective structure 310, and the other is detachably connected to the fourth end of the first protective structure 310 to enable the first protective structure 310 to switch between an open state and a closed state. Exemplarily, when the bottom plate 330 is movably connected to the third end of the first protective structure 310 and the top plate is detachably connected to the fourth end of the first protective structure 310, if the first radiation source 120 arranged near the first protective structure 310 needs maintenance, the first protective structure 310 can be disassembled from the top plate, while the first protective structure 310 is still connected to the bottom plate, and the first protective structure 310 is rotated to be in an open state, so that the first radiation source 120 is exposed to facilitate maintenance; similarly, when the top plate is movably connected to the third end of the first protective structure 310 and the bottom plate 330 is detachably connected to the fourth end of the first protective structure 310, if the first radiation source 120 arranged near the first protective structure 310 needs maintenance, the first protective structure 310 can be disassembled from the bottom plate 330, while the first protective structure 310 is still connected to the top plate, and the first protective structure 310 is rotated to be in an open state, so that the first radiation source 120 is exposed to facilitate maintenance. This solution adopts the above connection method, which can reduce the opening time of the first protective structure 310, thereby improving the maintenance efficiency of the first radiation source 120.

[0031] And / or, optionally, one of the bottom plate 330 and the top plate is movably connected to the third end of the second protective structure 320, and the other is detachably connected to the fourth end of the second protective structure 320, so that the second protective structure 320 can be switched between an open state and a closed state. Exemplarily, when the bottom plate 330 is movably connected to the third end of the second protective structure 320 and the top plate is detachably connected to the fourth end of the second protective structure 320, if the first radiation source 120 arranged near the second protective structure 320 needs maintenance, the second protective structure 320 can be disassembled from the top plate, while the second protective structure 320 is still connected to the bottom plate, and the second protective structure 320 is rotated to be in an open state, so that the first radiation source 120 is exposed to facilitate maintenance; similarly, when the top plate is movably connected to the third end of the second protective structure 320 and the bottom plate 330 is detachably connected to the fourth end of the second protective structure 320, if the first radiation source 120 arranged near the second protective structure 320 needs maintenance, the second protective structure 320 can be disassembled from the bottom plate 330, while the second protective structure 320 is still connected to the top plate, and the second protective structure 320 is rotated to be in an open state, so that the first radiation source 120 is exposed to facilitate maintenance. This solution adopts the above connection method, which can reduce the opening time of the second protective structure 320, thereby improving the maintenance efficiency of the first radiation source 120.

[0032] And / or, optionally, the bottom plate 330 and the top plate are both detachably connected to the first protective structure 310 so that the first protective structure 310 can be switched between an open state and a closed state. When the first radiation source 120 disposed near the first protective structure 310 needs to be repaired, the two ends of the first protective structure 310 are separated from the bottom plate 330 and the top plate respectively, and the first protective structure 310 is removed, so that the first radiation source 120 is exposed to facilitate its maintenance. This solution adopts the above-mentioned connection method, and when the first radiation source 120 needs to be repaired, the first protective structure 310 can be prevented from interfering with the staff; and it is convenient for the first security inspection device 100 and the second security inspection device 200 to be used separately.

[0033] And / or, optionally, the bottom plate 330 and the top plate are both detachably connected to the second protective structure 320, so that the second protective structure 320 can be switched between an open state and a closed state. When the first radiation source 120 arranged near the second protective structure 320 needs to be repaired, the two ends of the second protective structure 320 are separated from the bottom plate 330 and the top plate respectively, and the second protective structure 320 is removed, so that the first radiation source 120 is exposed to facilitate its maintenance. This solution adopts the above-mentioned connection method, and when the first radiation source 120 needs to be repaired, the second protective structure 320 can be prevented from interfering with the staff; and it is convenient for the first security inspection device 100 and the second security inspection device 200 to be used separately.

[0034] In addition, the connection method between the above-mentioned first protective structure 310 and the second protective structure 320 and the bottom plate 330 and the top plate can avoid opening connection holes on the device body 110 of the first security inspection device 100 and the device body 110 of the second security inspection device 200, which is beneficial to improving the structural strength of the device body 110.

[0035] In an optional embodiment, the security inspection device further includes a connection component 300 , and at least one of the device body 110 of the first security inspection device 100 and the device body 110 of the second security inspection device 200 is detachably connected to at least a portion of the connection component 300 . When any one of the first radiation source 120 of the first security inspection device 100 and the first radiation source 120 of the second security inspection device 200 fails, the corresponding security inspection device (such as the first security inspection device 100 and / or the second security inspection device 200) can be disassembled to repair the first radiation source 120 with the fault. At this time, the staff can check the first radiation source 120 from multiple angles, so as to more clearly see the fault of the first radiation source 120, and then repair the first radiation source 120; and when the first security inspection device 100 and the second security inspection device 200 are separated from the connecting component 300 respectively, the first security inspection device 100 and the second security inspection device 200 can be used separately, so as to be suitable for different application scenarios; in addition, the device body 110 and the connecting component 300 are connected in a detachable manner, which can be convenient for transportation. Of course, the device body 110 of the first security inspection device 100 and the connecting component 300, as well as the device body 110 of the second security inspection device 200 and the connecting component 300 can be connected in a fixed connection manner.

For example, when the first radiation source 120 of the first security inspection device 100 needs to be repaired, the device body 110 of the first security inspection device 100 is separated from the second end of the bottom plate 330, and then the first security inspection device 100 is rotated so that a space is formed between the first security inspection device 100 and the bottom plate 330, so that a staff can enter the space to repair the first radiation source 120 of the first security inspection device 100; similarly, when the first radiation source 120 of the second security inspection device 200 needs to be repaired, the device body 110 of the second security inspection device 200 is separated from the second end of the bottom plate 330, and then the second security inspection device 200 is rotated so that a space is formed between the second security inspection device 200 and the bottom plate 330, so that a staff can enter the space to repair the first radiation source 120 of the second security inspection device 200. This solution adopts the above connection method, which can reduce the time for disassembly and assembly between the security inspection device and the bottom plate 330, which is conducive to improving the efficiency of maintenance work. In addition, optionally, the connecting component 300 may also include a top plate, which may be connected in the same manner as the aforementioned bottom plate 330 with the device body 110 of the first security inspection device 100 and the device body 110 of the second security inspection device 200, and will not be described in detail to achieve the same effect.
