[0025] 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 only part of the embodiments of the present application, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present application and its application or use. Example 1

[0026] like Figure 1 , Figure 2 As shown, this embodiment provides a rotatable green channel vehicle detector, including a rotating vertical beam 1, a rotating device 3 and a driving device 4; a rotating device 3 is provided at the lower end of the rotating vertical beam 1, and the driving device 4 is drivingly connected to the rotating device for controlling the rotation of the rotating device 3.

[0027] A horizontal beam 2 is fixed to the upper end of the rotating vertical beam 1, and multiple receivers 7 are distributed inside the entire column of the horizontal beam 2 and the rotating vertical beam 1. A transmitter 6 is provided on the side of the rotating vertical beam 1. Multiple receivers 7 are distributed horizontally in the horizontal beam 2, and multiple receivers 7 are distributed vertically in the rotating vertical beam 1, and the receivers are located on the side facing the transmitter 6.

[0028] The transmitter 6 emits fan-shaped rays to scan the vehicle compartment passing by, penetrating the closed compartment and the cargo loaded therein. The scanning area absorbs the rays to different degrees. The rays of different intensities penetrating the compartment are received by the receivers 7 on the crossbeam 2 and the rotating vertical beam. The radiation signals received by the receiver 7 have different strengths, and thus different strengths of signals are output. After computer image processing, an image related to the outline and shape of the items loaded on the vehicle is generated and displayed on the computer screen. The image of the cargo in the compartment is displayed on the computer for inspection by the staff. Since the receiver 7 is provided throughout the column of the crossbeam 2 and the rotating vertical beam 1, when the vehicle passes through, the receiver can receive all the rays emitted by the transmitter 6 passing through the vehicle. The computer processes the received rays to form an image of the items inside the vehicle for inspection. Example 2

[0029] like Figure 3 , Figure 4 As shown, this embodiment provides a technical solution based on Embodiment 1, and is different from Embodiment 1 in that the rotating device 3 and the driving device 4 are both arranged on a base 5, and the base 5 is fixed on the ground.

[0030] The rotating device 3 includes a rotating gear 301, which is coaxially connected to the rotating vertical beam 1 through a rotating shaft. The driving device 4 includes a driving gear 401 and a driving motor 402. The driving gear 401 and the rotating gear 301 are engaged by gears. The driving gear 401 and the driving motor 402 are driven and connected. The driving motor 402 drives the driving gear 401 to rotate, and the driving gear 401 drives the rotating gear 301 to rotate, thereby causing the rotating vertical beam 1 on the rotating gear 301 to rotate.

[0031] When the height of the passing vehicle is higher than the height of the cross beam 2, the working instruction of the rotation angle is manually input, the driving motor 402 receives the working instruction of the control system, the driving motor 402 is started, and the driving gear 401 is driven to rotate, and the driving gear 401 drives the rotary gear 301 to rotate a certain angle, and the rotating vertical beam 1 is rotated a certain angle, and the cross beam 2 is rotated to be no longer above the vehicle, and the super-high vehicle can pass. After the vehicle passes, the rotating vertical beam rotates to its original state and continues to be used.

[0032] The above is only a preferred implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
