Description

Technical Field

[0001] This utility model relates to the technical field of highway green channel inspection equipment, and in particular to a smart green channel rapid inspection system for highways. Background Art

[0002] In recent years, the rapid inspection system using X-ray green channel has been increasingly used on highways. This system uses transmission radiation imaging technology, with a radiation source fixedly installed on one side of the lane and a radiation detector fixedly installed on the other side. When the vehicle to be inspected enters, the system will avoid the driver's cab and activate the X-ray to perform X-ray transmission imaging inspection on the container or closed vehicle body. Since goods of different densities absorb X-rays to different degrees, the intensity of the transmitted X-ray signal received by the detector is different. After processing the signals of different strengths, a vehicle scanning image can be generated, which can quickly inspect the vehicle without stopping or opening the container.

[0003] Existing rapid road clearance detection equipment cannot quickly clear the lane space when special oversized vehicles need to pass through the detection lane. The corresponding equipment needs to be disassembled, which is time-consuming and labor-intensive. It cannot automatically release the space occupied above the lane. Therefore, this utility model proposes a smart green channel rapid detection system for highways. Utility Model Content

[0007] As a further technical solution of this utility model, the foundation is laid with pre-embedded concrete between itself and the ground. There are three sets of foundations arranged in an array. The X-ray device is connected to the transmitter cabinet with bolts. The X-ray beam exit window corresponds to the X-ray device.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides a technical solution for a rapid detection system for smart green channels on highways: A rapid detection system for smart green channels on highways includes a foundation 1 and isolation water barriers 14. The upper end of the foundation 1 is equipped with a transmitter cabinet 2, a receiver cabinet 6, an entrance barrier 10, an exit barrier 11, a detection booth 12, and an LED screen 13. The transmitter cabinet 2 is equipped with a radiation device 3 and a collimator 5. A radiation beam exit window 4 is provided on one side of the radiation device 3. A cross arm 7 is provided on the upper end of the receiver cabinet 6. A rotating mechanism 8 is provided between the receiver cabinet 6 and the cross arm 7. Detectors 9 are installed inside both the receiver cabinet 6 and the cross arm 7.

[0020] The rotating mechanism 8 includes a hinge 81, a connecting rack 82 on one side of the cross arm 7, a moving slot 83 and a cavity 86 inside the receiver cabinet 6, a connecting block 84 on one side of the connecting rack 82, a first limit switch 85 on one side of the connecting block 84, a drive motor 87 inside the cavity 86, a drive gear 88 at the output end of the drive motor 87, and a second limit switch 89 on the top of the receiver cabinet 6.

[0021] like Figure 1-3As shown, the foundation 1 is laid with pre-embedded concrete between itself and the ground. There are three sets of foundation 1 arranged in an array. The X-ray device 3 is connected to the transmitting end cabinet 2 by bolts. The X-ray beam exit window 4 corresponds to the X-ray device 3. The collimator 5 is located on one side of the X-ray device 3. The receiving end cabinet 6 is connected to the cross arm 7 by a rotating mechanism 8. There are two sets of detectors 9 arranged symmetrically. The entrance barrier 10, the exit barrier 11, the detection booth 12, and the LED screen 13 are all installed on one side of the ground, which is conducive to the scanning and imaging detection of green channel vehicles.

[0022] like Figure 1-2 As shown, hinge 81 is located at the connection between the horizontal arm 7 and the receiving cabinet 6. The connecting rack 82 is fixedly connected to the horizontal arm 7. The connecting rack 82 has an arc-shaped structure. The moving slot 83 is adapted to the connecting rack 82. The connecting block 84 is fixedly connected to the connecting rack 82. The first limit switch 85 is connected to the connecting block 84 by bolts. The cavity 86 is connected to the moving slot 83. The cavity 86 has a rectangular structure. The drive motor 87 is connected to the cavity 86 by bolts. The output end of the drive motor 87 is fixedly connected to the drive gear 88. The drive gear 88 meshes with the connecting rack 82. The top of the receiving cabinet 6 has a mounting slot adapted to the second limit switch 89. The trigger end of the second limit switch 89 is located outside the mounting slot, which facilitates rotating the horizontal arm 7 by 90 degrees, releasing the space occupied above the passage. After the oversized vehicle passes, the horizontal arm 7 can be rotated back to the detection position to continue the green channel vehicle scanning and imaging detection.

[0023] The working principle of this utility model is as follows: During the use of the detection system, vehicle a enters the transmitting end cabinet 2 and receiving end cabinet 6 through the entrance barrier 10. The X-ray device 3 transmits X-rays through the X-ray beam exit window 4 to penetrate the vehicle and irradiate the receiving end cabinet 6. The detector 9 inside the receiving end cabinet 6 converts the X-rays into electrical signals and sends them to the host computer for imaging. When the detection channel needs to pass through special over-height vehicles, the channel space needs to be cleared. At this time, the horizontal arm 7 can be rotated 90 degrees by the rotating mechanism 8 at the top of the receiving end cabinet 6 to release the space occupied above the channel. After the over-height vehicle passes, the horizontal arm 7 can be rotated back to the detection position to continue the green channel vehicle scanning and imaging detection.

[0024] It should be noted that, through the setting of the rotating mechanism 8, when the cross arm 7 needs to rotate, the drive motor 87 is started, so that the output end of the drive motor 87 drives the drive gear 88 to mesh with the outer side of the connecting rack 82, causing the connecting rack 82 to rotate along the inside of the moving groove 83, so that the cross arm 7 rotates along the hinge 81 until one side of the cross arm 7 contacts the trigger end of the second limit switch 89, thereby feeding back to the controller, which then controls the output end of the drive motor 87 to stop running, and flips the cross arm 7 90 degrees, thereby releasing the space occupied above the detection channel, facilitating the passage of over-height vehicles for special operations.

[0025] It should be noted that when the cross arm 7 needs to be reset, the output end of the drive motor 87 drives the drive gear 88 to reverse, so that the drive gear 88 meshes with the outer side of the connecting rack 82, driving the connecting rack 82 to move along the inside of the moving groove 83 until the trigger end of the first limit switch 85 on the side of the connecting block 84 contacts the receiving cabinet 6, which feeds back to the controller, thereby controlling the output end of the drive motor 87 to stop running and reset the cross arm 7.

[0026] It should be noted that the extra-wide lanes at highway toll stations can be used by special extra-height vehicles such as those carrying military equipment or wind turbines. The rapid detection equipment for the green channel is also deployed in this extra-wide lane. Temporarily removing the equipment when special vehicles pass and then reinstalling it after the special vehicles have passed is time-consuming and laborious, and it affects the traffic efficiency of the toll station. Using this solution can quickly clear the lane space and improve traffic efficiency.

[0027] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
