[0031] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present disclosure. In the detailed description below, for ease of explanation, many specific details are set forth to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is apparent that one or more embodiments may also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessary confusion of the concepts of the present disclosure.

The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly specifying the number of the indicated technical features. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more of the aforementioned features.

[0034] The detailed background technology may include other technical problems in addition to the technical problem solved by the claim alone.

[0035] An embodiment of the present disclosure provides a vehicle security inspection device, comprising: a cabin 1, at least one opening 11 being provided on the cabin 1, wherein the cabin 1 comprises at least one detection channel, and the detection channel extends from the opening 11 toward the interior of the cabin 1; a conveying device 2 being arranged on the cabin 1 along the detection channel to drive the vehicle to be inspected to move on the detection channel; and a scanning device 3 being provided on the cabin 1 to scan and image the vehicle to be inspected on the detection channel.

[0036] The vehicle security inspection equipment in the embodiments of the present disclosure can be used at transportation hubs such as highways and ports to perform security checks on small vehicles passing through them. It is understood that the vehicle security inspection equipment of the present disclosure can also perform security checks on large vehicles or objects. When applicable to the security checks on large vehicles or objects, the size of the inspection channel and the scanning area of the scanning device can be adjusted.

[0037] The operating principle of the vehicle security inspection equipment in the embodiment of the present disclosure is that a vehicle to be inspected drives to opening 11 and stops on conveyor device 2, and the driver disembarks. Conveyor device 2 drives the vehicle to be inspected within inspection channel 17 of cabin 1, and passes through scanning device 3 at a certain speed. Scanning device 3 scans and images the vehicle to be inspected, allowing security personnel to determine whether the vehicle contains prohibited items, etc.

[0038] It can be understood that the shape of the cabin 1 in the embodiment of the present disclosure can be cube-shaped, spherical, tubular, etc., and an accommodating space is formed inside it to facilitate the formation of the detection channel 17 and the installation of the scanning device 3 and the conveying device 2.

[0039] It can be understood that the number of openings 11 in the embodiment of the present disclosure may be one or more. When the number of openings 11 is one, the vehicle to be detected enters and exits the cabin 1 through the opening 11. One specific implementation method is to enable the vehicle to be detected to enter and exit the cabin 1 from the same opening 11 through the forward and reverse movement of the conveying device 2. When the number of openings 11 is multiple, some of the openings 11 serve as detection entrances, and some of the openings 11 serve as detection exits. Multiple detection channels 17 can be set between the detection entrances and the detection exits, and a corresponding conveying device 2 is set in each detection channel 17, thereby realizing the detection of multiple vehicles to be detected; or multiple conveying devices 2 are set in the same detection channel 17, which share the same detection entrance and detection exit, and can also realize the detection of multiple vehicles to be detected.

[0040] It is understandable that the shape of the detection channel 17 can be straight, curved, or intersecting broken lines, etc., which can basically accommodate the vehicle to be detected. Further, the shape of the detection channel 17 can be designed accordingly according to actual detection needs.

[0041] It is understood that the conveyor device 2 can be of various forms, such as a common belt conveyor, chain conveyor, power-driven rollers, AGV, etc., which can basically transport the vehicle to be inspected. Preferably, the conveyor device 2 is located on the bottom wall 14 of the cabin 1 so that the vehicle to be inspected can directly drive onto the conveyor device 2, thereby improving inspection efficiency.

[0042] It can be understood that the scanning device 3 is the scanning device used in the existing vehicle security inspection process, which generally includes electrical equipment such as a radiation source, a detector, and a collimator. The equipment related to the above scanning device 3 is all set in the cabin 1 to facilitate subsequent transfer work.

[0043] Based on the above, in the vehicle security inspection equipment disclosed in the present invention, an opening 11 and a detection channel 17 are provided on the cabin 1 to facilitate the entry and exit of the vehicle to be inspected into the vehicle security inspection equipment. At the same time, the conveying device 2 and the scanning device 3 required for security inspection are integrated and designed on the cabin 1, realizing the integrated assembly of the vehicle security inspection equipment. Based on the structural design method disclosed in the present invention, when the vehicle security inspection equipment is transferred and installed, it is not necessary to separately construct and install the conveying device and the scanning device as described in the background technology. In the present invention, it is only necessary to place the cabin in the preset detection position, which effectively improves the installation efficiency of the vehicle security inspection equipment and reduces the complexity of its transfer installation.

[0044] like Figures 1 to 8 As shown, a specific implementation of the vehicle security inspection equipment in an embodiment of the present disclosure is shown.

[0045] See also Figure 1 and Figure 2 As shown, the cabin 1 in the embodiment of the present disclosure is a common rectangular parallelepiped structure, which adopts a hollow design in its length direction to construct a detection channel 17. Two openings 11 are arranged on the cabin 1 opposite to each other, located at the two ends of the detection channel 17. It can be understood that one of the two openings 11 is constructed as a detection entrance, and the other of the two openings 11 is constructed as a detection exit. The detection entrance and the detection exit are connected by the detection channel 17. The advantage of this structural design of the cabin 1 is that when the vehicle to be inspected undergoes security inspection, it can directly enter from the detection entrance and exit from the detection exit. When multiple vehicles undergo security inspection, an assembly line operation is adopted, and the vehicle in front will not hinder the movement of the vehicle behind, achieving uninterrupted inspection, thereby improving the efficiency of security inspection.

[0046] See also Figure 5 and Figure 6 As shown, in the embodiment of the present disclosure, the cabin 1 further includes: a door 12, which is movably arranged on the cabin 1. When the door 12 is closed, the cabin 1 is sealed, which can protect the internal conveying device 2, especially the scanning device 3, and prevent the loss of related equipment during the transfer and transportation of vehicle security inspection equipment. Figure 8As shown in FIG, when the cabin door 12 is fully closed, the entire cabin body 1 forms a sealed box structure to facilitate transportation and protect the equipment inside the cabin body 1.

[0047] like Figure 5 As shown in FIG, the hatch 12 in the embodiment of the present disclosure is hingedly mounted on the bottom wall 14 of the cabin body 1, see Figure 7 As shown, during the rotation of the hatch 12 around the edge of the bottom wall 14, the opening 11 is opened and closed. Figure 6 As shown in the figure, a hinge block 18 is provided on the hatch 12, a rotating shaft is provided on the hinge block 18, a groove cooperating with the hinge block 18 is processed on the bottom wall 14, a rotating hole is provided on the groove wall of the groove, and the rotating shaft is rotatably provided in the rotating hole. Under the driving of external force, the rotation of the hatch 12 is realized.

[0048] It is understood that there are various ways to open and close the hatch door 12 and various locations for its installation. In some embodiments, the hatch door 12 can be installed on the top wall or side wall of the cabin body 1, or portions of the hatch door 12 can be installed on the top wall, side wall, or bottom wall simultaneously, which can be spliced together to form a complete hatch door 12 when closed. In some embodiments, the hatch door 12 can be opened and closed by telescopic opening in the vertical direction or the left and right direction, such as a rolling door structure; or by sliding, such as a sliding door structure; or by opening and closing in a biparting manner, such as a double-door structure of a cabinet.

[0049] It is understandable that the opening and closing of the hatch 12 requires external force, or requires a related door driving device 13 to drive the hatch 12 to close or open the opening 11.

[0050] See also Figure 2 and Figure 3 As shown, the door drive device 13 in this embodiment is constructed as a cylinder, the cylinder body of which is hinged to the bottom wall 14 of the cabin body 1, and one end of the cylinder's telescopic rod is hinged to the cabin door 12. To facilitate the installation of the cylinder on the bottom wall 14 and the cabin door 12, a hinge seat 16 is provided at one end of the bottom wall 14 and the cabin door 12 that is close to each other. In the embodiment of the present disclosure, to ensure the stability of the opening and closing of the cabin door 12, the door drive device 13 is installed on both sides of the cabin door 12. The door drive device 13 is arranged on both sides of the cabin door 12 so as not to affect the operation of the vehicle to be inspected in the inspection channel 17.

[0051] It should be noted that the hydraulic cylinder in the embodiment of the present disclosure is manually actuated. Because the relevant power facilities may not be installed on-site during the on-site deployment of vehicle security inspection equipment, the manual actuation method allows the hatch 12 to be opened and closed without using on-site power facilities, thereby facilitating subsequent operations. Of course, if on-site conditions are good and relatively complete power facilities are available, electric actuation can be used to save manpower.

[0052] It should be noted that when the hatch door 12 is closed or in the process of opening, in order to prevent it from suddenly falling due to unexpected factors and posing a safety hazard, the oil cylinder in the embodiment of the present disclosure also has a self-locking device to control the hatch door 12 to stay in a preset position. The preset position can be the hatch door closed position or any position where the hatch door 12 is required to stay during on-site construction. The self-locking device of the oil cylinder can be a self-locking valve built into the oil cylinder.

[0053] It is understandable that in order to ensure the stability of the hatch 12 after closing, a relevant door lock structure, such as a door bolt, can be set on the hatch 12 to further fix the hatch 12 to prevent the hatch 12 from opening automatically due to road bumps during transportation.

[0054] It is understandable that in some embodiments, for the sake of structural simplification or cost reduction, the hatch 12 can be opened or closed manually within the allowable range of the weight of the hatch 12.

[0055] It is understandable that there are various structural forms of the door drive device 13. Depending on the different ways of opening the hatch 12, the door drive device 13 can be a push rod motor, a zipper structure, etc.

[0056] Figure 2 and Figure 5 The specific structure of the conveying device 2 in the embodiment of the present disclosure is shown. The conveying device 2 includes: a support roller group 21, two rows of support roller groups 21 are arranged in parallel and spaced apart along the detection channel, and the support roller group 21 includes a support frame arranged on the bottom wall 14 and a plurality of unpowered rollers, and the plurality of unpowered rollers are rotatably arranged side by side on the support frame. In this embodiment, two rows of support roller groups 12 are arranged side by side in the width direction of the detection channel, and a gap space is reserved between the two rows of support roller groups 12 to facilitate the subsequent installation of the belt conveyor 22. It should be noted that Figure 2The direction of the arrow in the figure indicates the direction of movement of the vehicle to be detected. The length direction of the detection channel is defined to be consistent with the above-mentioned direction of movement, and the width of the detection channel in the figure is defined to be perpendicular to the above-mentioned direction of movement. In the embodiment of the present disclosure, a belt conveyor 22 is used to transport the vehicle to be detected. The belt conveyor 22 is installed on the bottom wall 14 and arranged between two rows of support roller groups 21. Relevant installation holes are reserved on the bottom wall 14 to facilitate the installation of the belt conveyor 22. Furthermore, in the embodiment of the present disclosure, a conveying plate 23 is also provided on the conveying device 2, which is fixed on the conveyor belt of the belt conveyor 22 and supported by two rows of support roller groups 21 to be suitable for carrying the vehicle to be detected. Specifically, the conveying plate 23 is a common flat plate structure. A clamping block is provided at the middle position of the lower end surface of the conveying plate 23, and the conveyor belt is clamped in the middle of the clamping block to achieve the fixing of the conveying plate 23 on the conveyor belt. Both ends of the conveying plate 23 are overlapped on the support roller group 21. When the vehicle travels onto the conveying plate 23, it is supported by the support roller group 21 below, and the unpowered rollers in the support roller group 21 can rotate freely without hindering the movement of the conveying plate 23 set thereon.

[0057] It can be understood that in order to ensure the balance of force, the two support roller groups 21 are symmetrically arranged about the conveyor belt set at the middle position thereof, and at the same time ensure that the middle position of the conveying plate 23 in the width direction of the cabin coincides with the middle position of the width of the conveyor belt, so as to achieve that the two ends of the conveying plate 23 are supported at the same position.

[0058] It can be understood that in order to ensure that the vehicle to be inspected can stay stably on the conveying plate 23, a limiting protrusion 24 can also be set on the conveying plate 23 to prevent the conveying device 2 from stopping moving when the vehicle to be inspected completes the inspection, resulting in the risk of the vehicle moving forward under the action of inertia.

[0059] Further, see Figure 2 As shown, the support roller group 21 in this embodiment is extended on the hatch 12. The advantage of this arrangement is that the hatch 12 can be used as part of the detection channel. Because the vehicle needs to be parked on the conveying device 2 during detection, the vehicle has a body length. The vehicle is not scanned and detected when it is initially parked, so it needs to be away from the scanning device. Therefore, the body length will occupy the internal space of the cabin 1. When the hatch is open, at least part of the vehicle can stay on the hatch 12, and the position corresponding to the part of the hatch 12 does not need to be provided with the wall structure of the cabin 1, thereby reducing the volume of the cabin 1 as a whole.

[0060] Furthermore, in order to further reduce the volume of the cabin 1, the embodiment of the present disclosure also installs the drive device of the belt conveyor 22 on the cabin door 12. Therefore, a portion of the conveyor belt is installed on the cabin door 12. This is similar to the principle of installing the support roller assembly 21 on the cabin door 12, which can also effectively reduce the volume of the cabin 1. Because the conveyor belt is flexible, it can be folded closed when the cabin door 12 is closed, making it easy to operate.

[0061] Furthermore, in order to reduce the length of the belt conveyor in the embodiment of the present disclosure, the length of the conveyor plate can satisfy the following relationship: the size of the cabin 1 in the direction of the detection channel is L, and the size of the conveyor plate 23 in the direction of the detection channel satisfies greater than L / 2 and less than L. For example, the length of the conveyor plate in the embodiment of the present disclosure is approximately equal to L. When the length of the conveyor plate is approximately equal to L, the arrangement length of the belt conveyor is one end arranged on the cabin door 12 and the other end arranged in the middle position of the cabin 1. For example, when one end of the belt conveyor is arranged on the cabin door at the detection exit, when it is necessary to carry the vehicle to be detected at the detection entrance, when the conveyor plate 23 reaches the middle position of the cabin 1 under the drive of the conveyor belt, the conveyor plate 23 can already cover the cabin door 12 at the detection entrance, and then the vehicle to be detected can travel onto the conveyor plate 23.

[0062] It is understandable that during actual transportation, the conveyor plate 23 is fixed to the conveyor belt. The conveyor belt is a flexible object. When subjected to vibrations, the conveyor plate 23 and the support roller assembly 21 are prone to collision, generating noise. Even with large vibration amplitudes, the conveyor plate 23 may collide with the associated scanning device 3, causing damage to the equipment. Therefore, in the embodiments of the present disclosure, a limiting structure is provided on the conveyor plate 23. The limiting structure is used to secure the conveyor plate 23 to the bottom wall 14 during transportation of the vehicle security inspection equipment. The limiting structure can be a limiting pin structure, which is used to secure the conveyor plate 23 to the bottom wall 14 during transportation of the vehicle security inspection equipment.

[0063] It is understandable that, because the hatch 12 is also provided with a support roller assembly 21 in the embodiment of the present disclosure, during the transportation of the vehicle to be inspected, the vehicle to be inspected relies on the support of the support roller assembly 21 and is dragged forward by the conveyor belt. Therefore, it is necessary to ensure that the hatch 12 and the support roller assembly 21 in the cabin 1 are at the same horizontal height to prevent a height difference between the three, which would cause a fault and hinder the movement of the conveying plate 23. Therefore, the embodiment of the present disclosure also includes: adjustment struts 5. Multiple adjustment struts 5 are respectively provided on the bottom wall of the cabin 1 and the hatch 12. By controlling the height of the adjustment struts 5, the support roller assembly 21 on the bottom wall 14 and the hatch 12 can be adjusted to the same horizontal height. The adjustment struts 5 of the present disclosure are screw structures with support feet. Threaded holes or matching fixing nuts are provided on the cabin 1 and the hatch 12. The horizontal height of the cabin 1 and the hatch 12 can be adjusted by rotating the screws with a wrench or the like.

[0064] It is understandable that when the cabin body 1 is installed, there is a height difference between it and the horizontal plane of the installation location. The above-mentioned height difference is not conducive to the vehicle to be inspected entering the conveying device 2. Therefore, in the embodiment of the present disclosure, a guide plate 4 is also provided, which is detachably provided on the side of the cabin door 12 away from the cabin body 1, so as to be suitable for guiding the vehicle to be inspected to the conveying device 2. Specifically, two guide plates 4 are provided side by side at intervals on each cabin door 12, and the spacing between the two guide plates 4 is adapted to the spacing between the vehicles to be inspected. Preferably, in the direction of the inspection channel, the guide plate 4 and the support roller group 21 are provided in a collinear manner to ensure that when the vehicle to be inspected drives onto the conveying plate 23, its wheels are just supported by the support roller group 21, so as to ensure the stability of the conveying device 2 in supporting the vehicle to be inspected.

[0065] It can be understood that the guide plate 4 in the embodiment of the present disclosure is hung on the cabin door 12, and the specific structure is a hook and hanging shaft structure. When the cabin door 12 is closed, the guide plate 4 can be removed to facilitate the closing of the cabin door 12, or the guide plate 4 can be flipped along the hanging shaft to the inner side of the cabin door 12 and placed together inside the cabin body 1.

[0066] It can be understood that the detachable installation mode of the guide plate 4 allows a new guide plate 4 to be replaced when the wheelbase of the detected vehicle is larger or smaller to achieve adaptation.

[0067] See also Figure 3 As shown, scanning device 3 includes: a radiation source 31, mounted on the top wall of cabin 1; and detectors, mounted on the side walls 15 and bottom wall 14 of cabin 1. The specific structure of scanning device 3 is the same as that of scanning devices used in basic vehicle security inspections and will not be further described here. It should be noted that in the embodiment of the present disclosure, to facilitate the installation of detector 32, two vertical beams are disposed opposite each other on the two side walls 15 of cabin 1, and detector 32 is mounted on these vertical beams.

[0068] The present disclosure also provides a vehicle security inspection system comprising the vehicle security inspection apparatus described above and a display device configured to display a real-time image of the vehicle being inspected, generated by the scanning device. Security personnel use the real-time image displayed on the display device to determine whether the vehicle contains contraband, etc.
