Description

Technical Field

[0001] This invention relates to the field of customs cargo inspection technology, and in particular to an inspection device for large containers applicable to multiple scenarios. Background Technology

[0002] When goods, postal items, baggage, currency, gold and silver, securities, and means of transport enter or leave the country, customs must supervise and inspect them and levy tariffs in order to safeguard national sovereignty and interests and protect the country's economic development. Current inspection methods, especially for large containers, require large X-ray inspection machines. These machines not only occupy a lot of space but are also mostly limited to indoor use, resulting in significant limitations. Furthermore, they cannot be adapted to different container heights, leading to fixed power consumption and substantial energy waste. Simultaneously, because the effectiveness of X-ray inspection is relatively limited, manual spot checks are still necessary in case of anomalies. However, the limited space inside containers makes manual access very restrictive, making inspection operations cumbersome, time-consuming, and labor-intensive. Summary of the Invention

[0003] The technical problem this invention aims to solve is that the large X-ray inspection equipment currently used for inspecting large containers not only occupies a lot of space, but is also mostly limited to indoor use, resulting in significant limitations. Furthermore, it cannot be adaptively adjusted to different container heights, leading to fixed power consumption and substantial energy waste. Simultaneously, because the effectiveness of X-ray inspection is relatively limited, manual spot checks are still required in case of anomalies. However, the limited space inside a typical container restricts manual access, making inspection operations cumbersome, time-consuming, and labor-intensive.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a multi-scenario applicable large container inspection device, including two horizontally arranged bottom guide rails installed on the ground and an electrically driven assembly base movably installed on the bottom guide rails. The electrically driven assembly base includes a translation support base movably installed inside the bottom guide rails, a flip guide tube movably installed on the upper end of the translation support base, and an electrically controlled telescopic top frame for installing an X-ray inspection system slidably inserted into the opening of the flip guide tube. A top-side electrically controlled guide rail is fixedly installed on the side wall of the electrically controlled telescopic top frame, and a multi-angle adjustable extension bracket for installing a video shooting device is installed on the top-side electrically controlled guide rail by a screw.

[0005] The translation support includes an internal translation seat that is slidably inserted into the opening at the upper end of the bottom guide rail, a bottom-mounted electrically controlled support rod that is movably mounted on one side of the upper end of the internal translation seat, and a main drive wheel and a slave support wheel that are movably mounted at the lower end of the internal translation seat.

[0006] The electrically controlled telescopic top frame includes a main electrically controlled adjusting support rod axially inserted and fixed inside the opening of the flip guide tube, and an n-shaped outer frame that is slidably inserted into the opening of the flip guide tube. The inner side of the outer frame has an internal linkage bracket that is connected to the telescopic section of the main electrically controlled adjusting support rod.

[0007] The top-side electrically controlled guide rail includes a horizontal top-side guide rail fixedly installed on the side wall of the outer frame, a top-side electrically controlled screw movably installed inside the horizontal top-side guide rail, an internally threaded translational mounting seat threaded onto the top-side electrically controlled screw, a side-side recessed groove opened on the side wall of the internally threaded translational mounting seat, a side-side recessed support rod movably installed inside the side-side recessed groove, and a side-side movable mounting bracket fixed on the side wall of the internally threaded translational mounting seat for movably assembling a multi-angle adjustable extension bracket.

[0008] The multi-angle adjustable extension bracket includes a horizontally mounted flip-adjustable frame movably installed in a side-mounted movable mounting bracket via a lateral connecting shaft, a vertically mounted flip-adjustable frame movably installed inside the lower opening of the horizontally mounted flip-adjustable frame, a built-in control support rod movably installed on the top surface of the horizontally mounted flip-adjustable frame, a built-in assembly cylinder movably assembled in the vertically mounted flip-adjustable frame, and a side-mounted rotating motor for controlling the rotation of the built-in assembly cylinder.

[0009] The outer side of the built-in assembly cylinder is provided with a lateral assembly hole for installing a video shooting device, and the outer side of the vertically placed flip adjustment frame is provided with a lateral light-transmitting opening corresponding to the position of the video shooting device.

[0010] The outer side of the vertically placed flip-adjustable frame is fixedly equipped with strip lights on both sides of the side light-transmitting opening.

[0011] The bottom guide rail is movably fitted with a flip-type side-mounted protective cover.

[0012] The internal translation seat is provided with an upper flipping limit groove that cooperates with the flipping guide tube.

[0013] The beneficial effects of this invention are:

[0014] (1) The detection device for large containers with multiple application scenarios of the present invention adopts a flip-foldable design, which can be directly set up for outdoor use, has a wide range of applications, and can be stored when not in use, reducing the windward area and improving durability and safety.

[0015] (2) By adopting a liftable structure design, the adaptability of the transport vehicles of different heights can be adjusted, which can reduce detection energy consumption and reduce energy waste.

[0016] (3) By assembling a top-side electric control guide rail on the side wall of the electric telescopic top frame, and assembling a multi-angle adjustable extension bracket for installing a video shooting device on the top-side electric control guide rail, the device can be inserted into the container by changing the height and angle of the multi-angle adjustable extension bracket. The device can be inserted into the space at the top that people cannot enter, thereby recording video inside the container, making the detection methods more diverse and the use more convenient.

[0017] (4) The multi-angle adjustable extension bracket can not only be inserted into the container laterally, but also the vertical flip adjustment frame for installing video shooting devices and strip lights can be adjusted downward, so that goods of different heights can be observed at close range, and the observation area is wider.

[0018] (5) By opening a side-mounted recessed groove on the side wall of the internal threaded sliding mounting seat to move the side-mounted recessed support rod, the space utilization rate can be improved.

[0019] (6) The flip guide tube can be flipped and inserted into the upper flip limit groove to improve the structural firmness and consistency of the electric drive assembly seat on both sides of the bottom guide rail, and facilitate inspection.

[0020] (7) The entire device can be completely stored inside the flip-type side-mounted protective cover after being flipped downwards, which can effectively improve its protective performance when stored. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] Figure 1 , Figure 2 , Figure 3 and Figure 4 The large container inspection device applicable to multiple scenarios shown includes two horizontally arranged bottom guide rails 1 installed on the ground and an electrically driven assembly seat movably installed on the bottom guide rails 1. The electrically driven assembly seat includes a translation support seat movably installed inside the bottom guide rails 1, a flip guide tube 3 movably installed on the upper end of the translation support seat, and an electrically controlled telescopic top frame for installing an X-ray inspection system 4 slidably inserted into the opening of the flip guide tube 3. A top side electrically controlled guide rail is fixedly installed on the side wall of the electrically controlled telescopic top frame, and a multi-angle adjustable extension bracket for installing a video shooting device 5 is installed on the top side electrically controlled guide rail by screws.

[0029] Both the X-ray inspection system 4 and the video capture device 5 are existing technologies. The X-ray inspection system 4 has the same structure and principle as the traditional container X-scanning device on the market. The video capture device 5 uses a video camera to capture the external environment and then transmits the video information to the monitoring terminal.

[0030] In order to facilitate the adjustment of the angle of the flip guide tube 3, the translation support includes an internal translation seat 201 that is slidably inserted into the upper opening of the bottom guide rail 1, a bottom-mounted electrically controlled support rod 202 that is movably mounted on one side of the upper end of the internal translation seat 201, a main drive wheel 203 and a secondary support wheel 204 that are movably mounted on the lower end of the internal translation seat 201.

[0031] Both the bottom-mounted electrically controlled support rod 202 and the main drive wheel 203 are existing technologies. The bottom-mounted electrically controlled support rod 202 controls the flipping guide tube 3 to flip, thereby adjusting the height of the entire electrically controlled telescopic top frame, the top side electrically controlled guide rail, and the multi-angle adjustable extension bracket. Flipping upwards unfolds the device for use, while flipping downwards folds it in. The main drive wheel 203 drives the internal translation seat 201 to move synchronously along the bottom guide rail 1.

[0032] To facilitate assembly and adjustment of lifting, the electrically controlled telescopic top frame includes a main electrically controlled adjusting support rod 6 axially inserted and fixed inside the opening of the flip guide tube 3, and an n-shaped outer frame 7 slidably inserted at the opening of the flip guide tube 3. The inner side of the outer frame 7 has an internal linkage bracket 8 connected to the telescopic section of the main electrically controlled adjusting support rod 6.

[0033] The main electrically controlled adjusting support rod 6 is existing technology. It controls the outer frame 7 to extend outward along the flip guide tube 3, thereby changing the height of the entire detection device.

[0034] To accommodate the electric horizontal and tilting adjustments, the top-side electric control guide rail includes a horizontal top-side guide rail 10 fixedly mounted on the side wall of the outer frame 7, a top-side electric control screw 11 movably mounted inside the horizontal top-side guide rail 10, an internal threaded translation mounting seat 12 threaded onto the top-side electric control screw 11, a side-side recessed groove 13 formed on the side wall of the internal threaded translation mounting seat 12, a side-side recessed support rod 14 movably mounted inside the side-side recessed groove 13, and a side-side movable mounting bracket 15 fixed on the side wall of the internal threaded translation mounting seat 12 for movably assembling a multi-angle adjustable extension bracket.

[0035] Both the top-mounted electric control screw 11 and the side-mounted downward support rod 14 are existing technologies. The top-mounted electric control screw 11 consists of a side-mounted existing technology motor driving a top-mounted screw installed inside the horizontal top guide rail 10. The motor drives the top-mounted screw to rotate, thereby controlling the sliding adjustment of the internal thread translation mounting seat 12 inside the horizontal top guide rail 10. The side-mounted downward support rod 14 extends to control the outward flipping adjustment of the multi-angle adjustment extension bracket movably mounted on the side-mounted movable mounting bracket 15.

[0036] To facilitate adjustment, the multi-angle adjustment extension bracket includes a horizontally oriented tilting adjustment frame 16 movably mounted within a side-mounted movable mounting bracket 15 via a lateral connecting shaft, a vertically oriented tilting adjustment frame 17 movably mounted inside the lower opening of the horizontally oriented tilting adjustment frame 16, a built-in control support rod 18 movably mounted on the inner top surface of the horizontally oriented tilting adjustment frame 17, a built-in assembly cylinder 19 movably assembled within the vertically oriented tilting adjustment frame 17, and a side-mounted rotary motor 20 for controlling the rotation of the built-in assembly cylinder 19.

[0037] Both the built-in control strut 18 and the side-mounted rotating motor 20 are existing technologies. The built-in control strut 18 is used to control the vertical flip adjustment frame 17 to flip, eventually forming an angle of 90° or 180° with the horizontal flip adjustment frame 16, which then facilitates the video shooting device 5 on the built-in assembly cylinder 19 to shoot video of the low-positioned equipment.

[0038] A transverse worm gear is axially fixed on the right-side rotating shaft of the built-in control strut 18. An integrated worm wheel meshing with the transverse worm gear is located at the connecting end of the longitudinal tilting adjustment frame 17. An internal mounting groove for fixing and installing the built-in control strut 18 is provided on the inner top surface of the transverse tilting adjustment frame 16. The built-in control strut 18 drives the transverse worm gear to rotate, thereby driving the worm wheel to rotate and controlling the longitudinal tilting adjustment frame 17 to tilt downwards. When the longitudinal tilting adjustment frame 17 tilts outwards to 90°, the video shooting device 5 on the longitudinal tilting adjustment frame 17 can perform horizontal low-level shooting; when the longitudinal tilting adjustment frame 17 tilts outwards to 180°, the video shooting device 5 on the longitudinal tilting adjustment frame 17 can perform vertical high-level shooting, thus extending the length of the transverse tilting adjustment frame 16, suitable for video shooting inside long containers.

[0039] To facilitate filming, the outer side of the built-in mounting cylinder 19 is provided with a lateral mounting hole for mounting the video shooting device 5, and the outer side of the vertically placed flip adjustment frame 17 is provided with a lateral light-transmitting opening 21 corresponding to the position of the video shooting device 5.

[0040] In order to provide supplemental lighting for the low-light environment inside, strip lights 22 are fixedly installed on both sides of the side light-transmitting opening 21 on the outer side of the vertically placed flip-adjustable frame 17.

[0041] The strip fill light 22 is existing technology, used to illuminate and cooperate with the video shooting device 5.

[0042] To enhance protection by allowing the device to flip, a flip-type side-mounted protective cover 23 is movably mounted on the outer side of the bottom guide rail 1.

[0043] The bottom guide rail 1 has a lateral mounting frame with an outward protrusion at one end on its outer side surface. The flip-type side-mounted protective cover 23 is inserted into the lateral mounting frame through the connecting shafts on both sides of the connecting end to be movably assembled with the bottom guide rail 1. When the entire detection device is flipped down and folded for storage, the flip-type side-mounted protective cover 23 is placed on its outside. Then, the lock on the other end of the flip-type side-mounted protective cover is locked with the bottom guide rail 1 at the corresponding end. The locking method is the same as that of traditional mechanical locks. The lock tongue on the lock is directly extended into the lock groove on the outside of the bottom guide rail 1, which can prevent unauthorized personnel from damaging the entire device during idle time and improve the protection of the equipment in harsh environments.

[0044] In order to facilitate lateral positioning and improve structural robustness and stability, the internal translation seat 201 is provided with an upper flip-limiting groove 24 that cooperates with the flip guide tube 3.

[0045] When the bottom-mounted electric control support rod 202 is extended to control the flipping guide tube 3 to flip, the lower end of the flipping guide tube 3 is inserted into the upper-mounted flipping limit groove 24 by flipping, and one side is pressed against the inner wall of the upper-mounted flipping limit groove 24, thereby fixing and assembling with the internal translation seat 201.

[0046] Operating principle: Before inspection, the bottom-mounted electronically controlled support rod 202 controls the tilting guide tube 3 to tilt upwards, keeping it perpendicular to the upper end of the translation support seat 2. Then, the main electronically controlled adjustment rod 6 is controlled according to the height of the vehicle body, thereby changing the height of the electronically controlled telescopic top frame. The vehicle to be inspected is then driven into the bottom guide rails 1 on both sides. After the vehicle stops, the internal translation seat 201 in the bottom guide rails 1 on both sides is synchronously driven by the lower main drive wheel 23, reciprocating around the vehicle. The X-ray detection system 4 performs a lateral scan, and the type of object is determined by the attenuation of X-rays when penetrating different objects. If there is no abnormality, the vehicle drives away directly; if an abnormality occurs, the electronically controlled telescopic top frame is moved to the rear opening of the container, and then the container is opened. The rear door of the container is opened, and the height of the electrically controlled telescopic top frame is lowered using the main electric control adjustment strut 6. The horizontal tilting adjustment frame 16 is tilted outward by extending the side-mounted sinking strut 14. Then, the internal translation seat 201 drives the horizontal tilting adjustment frame 16 to be inserted from the rear opening of the container at the top angle. The top electric control screw 11 drives the internal thread translation mounting seat 12 to translate, thereby controlling the horizontal tilting adjustment frame 16 to translate at the upper part of the container. Video recording is performed by the video shooting device 5 on the vertical tilting adjustment frame 17. When it is necessary to detect the low position, the built-in control strut 18 starts to extend, controlling the vertical tilting adjustment frame 17 to tilt downward. When there is a gap between the goods inside, it can be translated within the gap between the goods, and detection is performed during translation.

[0047] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
