[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] Example 1

[0027] See Figures 1-6 The support base 1 serves as the basic support structure for the entire device. A set of support legs 2 are evenly installed on its bottom surface and are fixedly connected by bolts to ensure that the device is placed stably. The upper surface of the support base 1 is provided with a rotating groove 3. The placement plate 4 can rotate freely in the rotating groove 3 through its adaptation relationship with the rotating groove 3. The bottom wall of the rotating groove 3 has an annular groove 13. A set of sliders 14 connected to the bottom surface of the placement plate 4 are embedded in the annular groove 13 and can slide in it. This connection method makes the rotation of the placement plate 4 more stable and reduces shaking and friction.

[0028] Motor 5 is fixedly embedded in the bottom surface of the support base 1 by bolts. Its output shaft passes through the support base 1 and is rigidly connected to the center position of the placement plate 4 by a coupling. When motor 5 starts, it can directly drive the placement plate 4 to rotate in the rotating groove 3.

[0029] A limiting frame 601 is welded to the upper surface of the placement tray 4 to serve as the basic frame of the automatic flipping component 6. The motor 602 is fixedly embedded in the upper surface of the limiting frame 601. Its output shaft is connected to the top of the threaded rod 603 through a coupling. The bottom of the threaded rod 603 is rotatably connected to the inner wall of the limiting frame 601 through a bearing. The outer surface is threadedly connected to the moving block 604. When the motor 602 rotates, it drives the threaded rod 603 to rotate, thereby causing the moving block 604 to move up and down linearly along the threaded rod 603.

[0030] A stabilizing bracket 605 is welded to the outer surface of the movable block 604. A motor 606 is fixedly installed inside the stabilizing bracket 605 by bolts. The output shaft of the motor 606 is connected to the limiting frame 607 by a key. An annular groove 614 is opened on the outer surface of the stabilizing bracket 605. Two sliders 615 connected to the inner wall of the limiting frame 607 are embedded in the annular groove 614 and can slide. When the motor 606 is started, it can drive the limiting frame 607 to rotate smoothly around the stabilizing bracket 605.

[0031] The outer surface of the second limiting frame 607 is fixedly embedded with the fourth motor 608 by bolts. The output shaft of the fourth motor 608 is connected to the positive and negative lead screw 609 by a coupling. The end of the positive and negative lead screw 609 away from the fourth motor 608 is rotatably connected to the inner wall of the second limiting frame 607 by a bearing. Two clamping bars 610 are threadedly connected to the outer surface. Two guide grooves 612 are opened in the inner wall of the second limiting frame 607. Two guide blocks 613 are welded to the clamping bars 610 respectively, and the guide blocks 613 can slide in the guide grooves 612. When the fourth motor 608 rotates, the positive and negative lead screw 609 drives the two clamping bars 610 to move closer or further apart under the guidance of the guide blocks 613 and the guide grooves 612, so as to achieve the clamping and releasing of dangerous goods.

[0032] If the initial inspection reveals that the hazardous materials need to be flipped for inspection, the automatic flipping component 6 is activated. First, the motor 608 is started, which drives the positive and negative lead screws 609 to rotate. Due to the special thread structure of the positive and negative lead screws 609, the two clamping bars 610 approach each other under the guidance of the guide block 613 and the guide groove 612, and the hazardous materials are gently clamped by the protective pads 611.

[0033] Next, start motor 2 602. Motor 2 602 drives threaded rod 1 603 to rotate, causing moving block 604 to move upward along threaded rod 1 603, thereby lifting the dangerous item from the placement tray 4. After the dangerous item rises to a certain height, start motor 3 606. Motor 3 606 drives limit frame 2 607 to rotate 180° around the stable bracket 605. At this time, slider 2 615 slides in annular groove 2 614 to ensure that limit frame 2 607 rotates smoothly.

[0034] Finally, motor 602 reverses, causing moving block 604 to descend and place the flipped hazardous material back onto placement tray 4, completing the automatic flipping operation. After that, the preliminary inspection process is restarted to collect spectral information on the other side of the hazardous material.

[0035] A support frame 7 is bolted to the upper surface of the support base 1. The support frame 7 has a gate-shaped structure and provides support for other components. Two LED lights 8 are bolted to the inner wall of the support frame 7. The light emitted by the LED lights 8 can evenly illuminate the dangerous items on the placement tray 4, providing good lighting conditions for the detection of the hyperspectral imager 11.

[0036] An electric push rod 9 is fixedly embedded in the upper surface of the support frame 7 by bolts. The output end of the electric push rod 9 is connected to the mounting bracket 10 by bolts. The electric push rod 9 can push the mounting bracket 10 up and down by extending and retracting the telescopic rod, thereby adjusting the height of the hyperspectral imager 11 inside the mounting bracket 10.

[0037] The mounting bracket 10 is a hollow frame structure, inside which a hyperspectral imager 11 is placed. The mounting assembly 12 is used to fix the hyperspectral imager 11. It includes two threaded rods 121 threaded to the outer surface of the mounting bracket 10. The ends of the threaded rods 121 close to each other are rotatably connected to the clamping plate 122 through bearings. A rotating block 123 is fixed to the end of the threaded rods 121 away from the clamping plate 122. A sliding groove 124 is opened in the inner wall of the mounting bracket 10. Two sliders 125 are welded to the clamping plate 122 and can slide in the sliding groove 124. By rotating the rotating block 123, the extension and retraction of the threaded rods 121 can be adjusted, so that the clamping plate 122 clamps or releases the hyperspectral imager 11.

[0038] When it is necessary to inspect hazardous materials, first place the hazardous materials on the placement tray 4, and the operator turns on the LED lighting 8 to provide sufficient and uniform lighting for the inspection area. Then, start the motor 5. The motor 5 drives the placement tray 4 to rotate at a stable speed in the rotating groove 3. At the same time, the slider 14 slides in the annular groove 13 to ensure that the placement tray 4 rotates smoothly.

[0039] Start the electric push rod 9, and adjust the height of the mounting bracket 10 and the hyperspectral imager 11 according to the height and shape of the hazardous material, so that the hyperspectral imager 11 is in the optimal detection position. The hyperspectral imager 11 uses its function of decomposing light and collecting spectral information to scan the surface of the hazardous material during the rotation process and obtain the spectral information of the surface of the hazardous material.

[0040] The working principle of this utility model is that the operator first carefully places the dangerous item to be inspected at the center of the upper surface of the placement tray 4 to ensure that the item is placed stably and to avoid affecting the acquisition of spectral information due to shaking during subsequent inspection.

[0041] Rotate the rotating block 123 and adjust the threaded rod 121 in the mounting assembly 12. As the threaded rod 121 rotates, the clamping plate 122, guided by the slider 125 and the slide groove 124, gradually approaches the hyperspectral imager 11 until the hyperspectral imager 11 is firmly clamped. At the same time, check whether the connection lines of the hyperspectral imager 11 are stable to ensure that it can work normally.

[0042] Debug each motor (Motor 1 5, Motor 2 602, Motor 3 606, Motor 4 608) and electric push rod 9. Check whether the power cord of the motor is connected correctly, whether the rotation direction of the motor is as expected, check whether the telescopic rod of electric push rod 9 can extend and retract normally, and whether the stroke meets the inspection requirements. At the same time, check whether the LED lighting lamp 8 can emit light normally and whether the light intensity is uniform.

[0043] The operator turns on the LED light 8, which emits a soft and uniform light to illuminate the entire inspection area, providing good lighting conditions for the hyperspectral imager 11 to perform its work.

[0044] Start motor 5. The output shaft of motor 5 drives the placement disk 4 to rotate smoothly in the rotating groove 3 at a set speed. At the same time, the slider 14 in the annular groove 13 assists the rotation of the placement disk 4, reducing friction and shaking.

[0045] Based on the approximate height of the hazardous material, the operator activates the electric push rod 9 via the control panel. The telescopic rod of the electric push rod 9 extends or retracts, pushing the mounting bracket 10 and the hyperspectral imager 11 to move up and down, adjusting the hyperspectral imager 11 to a suitable height, so that the hyperspectral imager 11 maintains the optimal detection distance between the hyperspectral imager 11 and the hazardous material.

[0046] Once the placement disk 4 has rotated stably and the height of the hyperspectral imager 11 has been adjusted appropriately, the hyperspectral imager 11 begins to work. It performs an all-round scan of the surface of the hazardous material during the rotation process, decomposes the light reflected by the hazardous material into continuous spectral bands, and collects the intensity information of each spectral band. By analyzing the intensity information of the spectral bands, it is convenient to inspect the hazardous material.

[0047] If the preliminary inspection results indicate that the hazardous materials need to be flipped for inspection, the operator starts the automatic flipping assembly 6. First, the motor 608 is started. The motor 608 drives the positive and negative lead screws 609 to rotate. Under the guidance of the guide block 613 and the guide groove 612, the two clamping bars 610 move closer to each other and gently clamp the hazardous materials with the protective pads 611 to ensure that the materials are not damaged during the flipping process.

[0048] Next, start motor 2 602. Motor 2 602 drives threaded rod 1 603 to rotate, causing moving block 604 to move upward along threaded rod 1 603, lifting the dangerous item from the placement tray 4 to a certain height.

[0049] After the hazardous material is raised to the appropriate position, motor 3 606 is started. Motor 3 606 drives limit frame 2 607 to rotate 180° around the stable support 605. During the rotation, slider 2 615 slides in the annular groove 2 614 to ensure that limit frame 2 607 rotates smoothly.

[0050] After motor 3 606 completes its rotation, motor 2 602 reverses, causing moving block 604 to descend and smoothly place the overturned hazardous material back onto the placement tray 4.

[0051] Restart motor 5 to continue rotating placement tray 4. At the same time, adjust electric push rod 9 again according to the state of the hazardous material after flipping to ensure that hyperspectral imager 11 is in the optimal detection position. Hyperspectral imager 11 scans the surface of the hazardous material after flipping again to collect spectral information of the other side of the hazardous material.

[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
