When the protective wall 2 is positioned on the side surface of the scanning inspection vehicle 1, the coupling device acts on the protective wall 2 to enable the protective wall 2 to synchronously walk along with the scanning inspection vehicle 1 so as to form a scanning isolation channel 14 between the protective wall 2 and the scanning inspection vehicle 1, and the scanning channel is positioned in the scanning isolation channel 14.
When the scanning inspection system scans an inspected object, the protective wall 2 and the scanning inspection vehicle 1 synchronously walk, the protective wall 2 can reduce radiation protection requirements on the field, and the application range is wide.
In some embodiments, the coupling device comprises a mechanical connection structure arranged on the scanning inspection vehicle 1 and the protection wall 2, the mechanical connection structure is used for detachably connecting the scanning inspection vehicle 1 and the protection wall 2, and the protection wall 2 is driven by the scanning inspection vehicle 1 to synchronously walk along with the scanning inspection vehicle 1 through the mechanical connection structure.
In the embodiment shown in fig. 1 to 9, the mechanical connection comprises at least one connection arm 3 arranged on the scanning inspection vehicle 1 and/or the protective wall 2. In the present embodiment, two connecting arms 3 are provided at both front and rear ends of the top of the body 11 of the scanning inspection vehicle 11.
In some embodiments, the connecting arm 3 is foldable and/or retractable.
In some embodiments, the connecting arm 3 has a stowed state and an extended state. In the stowed state, the connecting arm is disconnected from the protective wall 2, and the connecting arm 3 is retracted and/or folded and placed on the vehicle body 11. In the extended state, the connecting arm is extended and/or unfolded, and the connecting arm 3 is connected with the protection wall 2.
In the embodiment shown in fig. 1 to 9, the vehicle body 11 includes a turntable 111 provided at the top end of the vehicle body 11 and rotatable about a vertical axis. The connecting arm 3 includes a first arm section 31, a second arm section 32, and a third arm section 33. The first end of the first arm segment 31 is hinged to the turntable 111 or is telescopically arranged within the turntable 111.

The scanning inspection system is a self-propelled scanning inspection system, and when scanning inspection is executed, the scanning inspection vehicle 1 and the protective wall 2 synchronously travel, and the scanning inspection system drives through an inspected object to complete a scanning process. The object to be inspected may be, for example, a container, a vehicle, or the like.
After the scanning is completed, the scanning arm of the scanning system 12 of the scanning inspection vehicle 1 is retracted, the third arm section of the scanning arm is folded to be parallel to the second arm section, the third arm section and the second arm section are rotated together until the length directions of the top of the vehicle body 11 to the third arm section and the second arm section are consistent with the front-back direction, and the first end of the first arm section is retracted, and the scanning arm is wholly lowered to an initial position and is in a retracted state. The connecting arm 3 of the scanning inspection vehicle 1 is disconnected from the protective wall 2, the scanning inspection vehicle 1 is separated from the protective wall 2, the third arm section 33 of the connecting arm 3 is folded to be parallel to the second arm section 32, the third arm section 33 and the second arm section 32 are rotated together until the length direction from the top of the vehicle body 11 to the third arm section 33 and the second arm section 32 coincides with the front-rear direction, and the first end of the first arm section 31 is retracted, the connecting arm 3 is lowered to the initial position as a whole, and the connecting arm 3 is in the retracted state.
In some embodiments, which are not shown, the coupling device may include a driving device for driving the protective wall 2 to walk and a controller connected with the driving device in a signal manner, where the controller controls the driving device to act according to the walking speed of the scanning inspection vehicle 1 so as to control the protective wall 2 to walk synchronously with the scanning inspection vehicle 1.
The controller may be a general-purpose processor, a Programmable Logic Controller (PLC), a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), or the like, which can realize the above control functions.
The coupling device may comprise a speed measuring device in order to obtain the travelling speed of the scanning inspection vehicle. The control device may also be in signal connection with a speedometer of the scanning inspection vehicle to obtain the speed of the scanning inspection vehicle.
As can be seen from the above description, the above embodiments of the present invention have at least one of the following technical effects:
1) When the scanning inspection system scans an inspected object, the protective wall 2 and the scanning inspection vehicle 1 synchronously walk, the radiation protection requirement on the field can be reduced by the protective wall 2, and the application range is wide.
2) The scanning system 12 of the scanning inspection vehicle 1 works independently relative to the protective wall 2, and is not required to be debugged again after being combined with the protective wall 2.
3) The scanning inspection vehicle 1 and the protective wall 2 can be disassembled for transportation, so that the transportation difficulty is reduced.
4) The connecting arm 3 and the scanning system 12 on the scanning inspection vehicle 1 can be retracted, so that the occupied area and the space height are reduced, and the scanning inspection vehicle is easy to store and transport.
