The above-mentioned sea container has certain anti-shock performance, but the buffering structure cannot be known before use because the sea surface conditions are relatively variable. If the container is used without detection, the goods inside the container may be damaged during transportation, resulting in corresponding losses and compensation. If the goods are damaged due to inertia, the loss will be further expanded. In this process, personnel cannot obtain impact data from the damaged container, and can only continuously try to change the container scheme, which requires a large amount of economic investment to test the best container scheme in multiple attempts. If the manufacturer is near the coast, the anti-rolling performance of the sea container can be tested before the container is formally shipped, but the cost of real scene testing is high, and most manufacturers are currently located inland, making it difficult to design and verify the container scheme.

Detailed Implementation

[0018] The invention will be further described below with reference to the accompanying drawings.

[0019] First, it should be clarified that the terms "before" and "after" in this application refer to... Figure 2 Based on the directions shown, the left side is the "front" of the container body 15, and the right side is the "rear" of the container body 15.

[0020] like Figures 1 to 11As shown, the marine container verification system comprises a container body 15 with a goods inlet, the container body 15 comprises a skeleton 1, the front side and the rear side of the skeleton 1 are provided with side plates 2, the force detection devices are arranged between the side plates 2 and the skeleton 1, the bottom of the skeleton 1 is provided with an adjusting mechanism 3, the adjusting mechanism 3 is used to drive the container body 15 to reciprocate forward and backward, so that an inclination angle is formed between the plane where the bottom of the skeleton 1 is located and the horizontal plane, and the inclination angle is an acute angle. The force detection device comprises a pressure sensor (the pressure sensor converts physical pressure into an electric signal through a sensitive element) arranged between the side plate 2 and the skeleton 1, and the pressure sensor is electrically connected with a central processing unit (Central Processing Unit, CPU, which is responsible for interpreting computer instructions and processing software data, and is the final execution unit of information processing and program running), wherein the number of the pressure sensors can be increased according to actual needs. The goods inlet can be located at any one of the two ends of the container body 15, and preferably the two ends of the container body 15 are both open ends, that is, as shown in the orientation Figure 1 , the left and right sides of the container body 15 in the orientation can be the goods inlet. As shown in the orientation Figure 11 , the adjusting mechanism 3 comprises a swing seat with an arc-shaped bottom arranged at the bottom of the container body 15, the container body 15 is provided with adjusting piles on the front and rear sides, the adjusting piles are provided with electric cylinders, the extension ends of the electric cylinders are connected to the semicircular base rings near the container body 15, the electric cylinder on one side of the container body 15 is elongated, the electric cylinder on the other side is shortened to drive the swing seat to swing, and then drive the container body 15 to swing forward and backward.

[0021] Before detection, first, the goods to be loaded in the container are loaded into the skeleton 1 from the goods inlet according to the previously determined container scheme. It should be noted that because the detection of the verification system is based on the actual situation of the marine container, the size and weight of the goods loaded into the skeleton 1 of the container body 15 should meet the requirements of GB / T1413-2023, that is, the container scheme needs to meet the requirements of GB / T1413-2023. After the goods are loaded, personnel take pictures from the side of the skeleton 1 to record the actual position of the goods in the container body 15 during the initial loading and unloading process, and then the front side and rear side of the skeleton 1 are hoisted to the appropriate installation position and installed under the cooperation of the crane. After the installation of the side plate 2 is completed, the stress detection device is installed between the side plate 2 and the corresponding skeleton 1, that is, the plurality of pressure sensors are placed between the skeleton 1 and the side plate 2. It is worth noting that this step can install the pressure sensor on the skeleton 1 before the side plate 2 is installed on the skeleton 1, but if the pressure sensor is installed in advance, the probability of damage to the pressure sensor will be larger, so it is recommended to install it later. During the installation process, first, the pressure sensor is inserted into the gap between the side plate 2 and the skeleton 1, and then it is fixed on the skeleton 1 using screws, or other fixing methods such as glue can be used for installation. After the installation of the pressure sensor is completed, there will be an initial pressure value, and the preparation work is completed. Then personnel control the adjusting mechanism 3 to start, and the adjusting mechanism 3 works, such as Figure 3As shown, the bottom plane of the skeleton 1 is inclined upward to the front side of the skeleton 1, the container body 15 will be inclined as a whole, and the goods in the skeleton 1 will also have a tendency to incline. When the included angle A between the bottom plane of the inclined skeleton 1 and the horizontal plane, i.e. the inclination angle, reaches the highest angle of measurement (preferably, the highest angle of the verification system is 30 degrees), the adjusting mechanism 3 drives the bottom of the skeleton 1 to fall back to the horizontal plane and starts to incline downward, and finally reaches the lowest angle of measurement (preferably, the highest angle of the verification system is -30 degrees), and then the adjusting mechanism 3 drives the bottom of the skeleton 1 to fall back to the horizontal plane, and the adjusting mechanism 3 stops running. In this process, if the goods in the skeleton 1 slip, the package disintegrates, etc., the scattered goods or the complete goods will move and hit the side plate 2, i.e. the side plate 2 where the pressure sensor is installed is hit, at this time the side plate 2 will vibrate, the positional relationship between the side plate 2 and the skeleton 1 will vibrate, and the corresponding pressure sensor will detect a fluctuation in the value. Personnel can intuitively understand the phenomenon of the goods after being transported in the actual sea container. After the test is completed, the side plates 2 on the front side and the rear side of the skeleton 1 are removed, and the goods in the skeleton 1 are photographed again. Comparing this photograph with the previously photographed photograph, it can be observed whether the goods have slipped or scattered, and to some extent, it verifies the stability of the container scheme for the goods itself, avoids the situation that the goods are not stable due to the container itself when encountering waves, and causes the goods to collide with each other, resulting in damage to the goods. The comparison of the front and rear photographs can be compared by the central processor or by the naked eye of personnel. If the photograph comparison shows that the goods have slipped and scattered, the data obtained by the pressure sensor has data fluctuation (the data fluctuation value needs to exclude the influence of the weight of the side plate 2 due to the change in the angle, this interference data can be measured when there is no goods in the skeleton 1, and the final data is deleted), etc., it indicates that the container scheme is not feasible, and should be modified and verified again. If there is no above-mentioned situation, the container scheme passes the anti-rolling performance verification and can normally be sea-transported. It is worth noting that in this design, the side plate 2 can be arranged on the inner side of the skeleton 1 or on the outer side of the skeleton 1. When the side plate 2 is hit, the value of the pressure sensor increases when the side plate 2 is arranged on the inner side of the skeleton 1; when the side plate 2 is hit, the value of the pressure sensor decreases when the side plate 2 is arranged on the outer side of the skeleton 1. Correspondingly, the values of the influence of the weight of the side plate 2 arranged on the inner side or the outer side of the skeleton 1 on the pressure sensor are different, which can be obtained through experiments.

[0022] The container body 15 is formed by the framework 1 and the side plates 2, and the container body 15 is driven by the adjusting mechanism 3 to swing back and forth to simulate the swinging of the container on the sea (the inclination angle in the verification system can simulate the roll angle of the ship in the sea transportation standard, the roll angle is a core parameter for measuring the lateral swing amplitude in ship engineering, and is defined as the instantaneous angle between the lateral axis of the ship and the horizontal plane, and the swing amplitude of the ship is also the swing amplitude of the container placed on the ship), so as to simulate the swinging state of the container on the sea, verify whether the container scheme can cope with the sea transportation, reduce the movement or scattering of goods in the actual transportation process, and test whether the goods collide with the container during the transportation process, and the specific collision value, so as to better make adjustment and change.

[0023] The adjusting mechanism 3 includes a first lifting assembly 16 and a second lifting assembly 17 hinged to the bottom of the framework 1 and distributed on both sides of the lateral center axis of the framework 1. Figure 3 When the container body 15 needs to swing forward, the first lifting assembly 16 remains unchanged, the second lifting assembly 17 starts to rise, the container body 15 swings forward, and the inclination angle (angle A in Figure 3 ) starts to increase with the rising of the first lifting assembly 16, when the inclination angle reaches the maximum angle for detection (preferably, the angle is 30 degrees), the second lifting assembly 17 starts to descend, until the inclination angle becomes 0 degrees, that is, the second lifting assembly 17 returns to the initial position, and the forward swing is completed. Figure 4 When the container body 15 needs to swing backward, the first lifting assembly 16 starts to rise, the second lifting assembly 17 remains unchanged, the container body 15 swings backward, and the inclination angle starts to decrease with the rising of the first lifting assembly 16, when the inclination angle (angle A in Figure 4 ) reaches the minimum angle for detection (preferably, the angle is -30 degrees), the first lifting assembly 16 starts to descend, until the inclination angle becomes 0 degrees, that is, the first lifting assembly 16 returns to the initial position, and the backward swing is completed. In the design, the personnel can change the running speed of the first lifting assembly 16 and the second lifting assembly 17 to simulate different sea conditions, and better verify the container scheme for sea transportation. The first lifting assembly 16 and the second lifting assembly 17 are consistent in structure and are each a plurality of electric cylinders arranged along the lateral center axis of the framework 1. The extension end of the electric cylinder is hinged to the framework 1. The electric cylinder has stable movement and high control precision, and is convenient for adjusting the inclination angle.

[0024] The force detection device is a door magnetic switch 4 arranged between the side plate 2 and the framework 1, and the door magnetic switch 4 is electrically connected with the adjusting mechanism 3. In this embodiment, the door magnetic switch 4 is connected in series with the adjusting mechanism 3, the side plate 2 is arranged outside the framework 1, the door magnetic switch 4 includes two components of a magnet part and a switch body part, the switch body part is arranged on the framework 1, the magnet part is arranged on the side plate 2, the switch body part and the magnet part are attracted to each other when installed, the circuit is connected, and the adjusting mechanism 3 is powered at this time. When the side plate 2 is impacted and vibrates, the magnet part and the switch body part are disconnected due to vibration and start to alarm, and at the same time, the door magnetic switch 4 is disconnected to disconnect the circuit, and the adjusting mechanism 3 stops running. This design can greatly avoid the continuous tilting of the container when the goods in the container tilt, that is, reduce the occurrence of the situation that the goods hit the side plate 2 to separate from the container.

[0025] Preferably, the side plate 2 includes a plurality of unit plates 23 detachably connected with the framework 1, a door magnetic switch 4 is arranged between any unit plate 23 and the framework 1, and a plurality of door magnetic switches 4 are electrically connected with the adjusting mechanism 3. This design can increase the sensitivity of the verification system, that is, the whole side plate 2 is divided into a plurality of unit plates 23, and the unit plate 23 is obviously impacted, so that the detection is more accurate, and if one of the unit plates 23 is damaged, only one unit plate 23 needs to be replaced, thereby saving the cost of subsequent replacement and maintenance.

[0026] The hydraulic system transmits power through liquid, has no mechanical rigid connection, reduces vibration and impact, and avoids external factors from affecting the verification result of the verification system The adjusting mechanism 3 comprises an electrically connected pumping station, a third lifting assembly 18 and a fourth lifting assembly 19 connected with the electrically connected pumping station, the electrically connected pumping station is electrically connected with the door magnetic switch 4, the third lifting assembly 18 and the fourth lifting assembly 19 are distributed on both sides of the lateral middle axis of the framework 1, the third lifting assembly 18 and the fourth lifting assembly 19 are consistent in structure and each comprises a plurality of oil cylinders 5 arranged at intervals along the lateral middle axis of the framework 1. The telescopic end of the oil cylinder 5 is hinged to the bottom of the framework 1, the bottom of the framework 1 has two hinge shafts, the plurality of oil cylinders 5 in the third lifting assembly 18 and the plurality of oil cylinders 5 in the fourth lifting assembly 19 are respectively sleeved on the corresponding hinge shafts. The electrically connected pumping station is used for controlling the lifting of the oil cylinder 5, wherein all the oil cylinders 5 in the third lifting assembly 18 are connected in series, and all the oil cylinders 5 in the fourth lifting assembly 19 are also connected in series. In the process of verifying the operation of the system, the front and rear swinging of the container body 15 is realized through the lifting of the third lifting assembly 18 and the fourth lifting assembly 19, and the specific operation principle can be referred to the operation principle of the first lifting assembly 16 and the second lifting assembly 17. When the door magnetic switch 4 is connected or disconnected, the electrically connected pumping station stops working, then either the third lifting assembly 18 or the fourth lifting assembly 19 will immediately stop working, this design can directly stop the continuous starting of the adjusting mechanism 3 when the goods hit the side plate 2, thereby reducing the occurrence of the goods rushing out of the container body 15 and improving the safety of the verification system.

[0027] The platform 6 is also included, and the adjusting mechanism 3 is detachably arranged on the platform 6. The platform 6 is made of cement pouring, a plurality of bolts are pre-buried in advance when the platform 6 is poured, and the first lifting assembly 16 and the second lifting assembly 17 can be installed and positioned through the bolts. This design makes the container body 15 in the verification system have a relatively horizontal initial position, which is more convenient for adjusting the inclination angle in the later stage, and can also facilitate the installation of the adjusting mechanism 3.

[0028] The frame 1 is formed by welding the bottom frame 7, the front side frame 9, the rear side frame 8 and the top frame 10. The front side frame 9 and the rear side frame 8 are the same structure. The top frame 10 is provided with a pair of mounting grooves 11 on the ring side. The unit plate 23 is an L-shaped plate. The short plate end of the plurality of L-shaped plates is inserted into the corresponding mounting groove 11. The long plate part of the plurality of L-shaped plates is respectively detachably connected with the corresponding one of the front side frame 9 and the rear side frame 8. Preferably, the front side frame 9 and the rear side frame 8 are the same structure and each include a plurality of stand column angle steels 21 arranged between the bottom frame 7 and the top frame 10. The unit plate 23 is arranged between any two stand column angle steels 21. The stand column angle steel 21 includes a detection part and a mounting part perpendicular to each other. The unit plate 23 and the mounting part of the stand column angle steel 21 are connected by a plurality of mounting angle steels 20. The unit plate 23 and the mounting angle steel 20 are connected by a nylon rivet 22. The mounting angle steel 20 abuts against the mounting part of the stand column angle steel 21. A plurality of door magnetic switches 4 are arranged between the unit plate 23 and the detection part of the stand column angle steel 21. Preferably, the groove width of the mounting groove 11 is greater than the thickness of the L-shaped plate. When the short plate of the L-shaped plate is inserted into the mounting groove 11, the L-shaped plate can be first positioned and supported, and then subsequently installed. In this design, the unit plate 23 is abutted against the stand column angle steel 21 on both sides by the nylon rivet 22 and the mounting angle steel 20, thereby completing the installation of the unit plate 23 and reducing the resistance to the force movement of the unit plate 23 to a certain extent. When the unit plate 23 is impacted, it can smoothly move, thereby improving the probability of the door magnetic switch 4 being disconnected when the unit plate 23 is impacted, improving the detection accuracy of the verification system. At the same time, in order to avoid the unit plate 23 from being directly separated when it is displaced, the unit plate 23 is arranged as an L-shaped plate and is arranged in cooperation with the mounting groove 11, thereby reducing the probability of the unit plate 23 being directly separated from the frame 1. Preferably, a second lifting lug 24 is arranged on the long plate of the L-shaped plate close to the short plate, thereby facilitating the hoisting of the side plate 2.

[0029] Further, a plurality of scale marks 12 are arranged on the inner side of the bottom frame 7, the inner side of the front side frame 9 and the inner side of the rear side frame 8. The bottom frame 7 includes a pair of bottom frame 7 angle steels. A bottom side angle steel is arranged between the pair of bottom frame 7 angle steels. A bottom rib angle steel is arranged between any two bottom side angle steels. The bottom side angle steel and the inner side of the bottom frame 7 angle steel are each provided with a scale mark 12. The stand column angle steel 21 of the front side frame 9 and the rear side frame 8 is also provided with a scale mark 12. The arrangement of the plurality of scale marks 12 can enable the person to accurately record the specific position and height of the goods when taking a photo after loading the goods. When the verification and detection are completed, the position can be better compared to understand whether the goods are displaced. To a certain extent, the stability of the container scheme for the goods itself is verified. The goods are not stable when encountering a storm. The impact between the goods causes damage to the goods.

[0030] The skeleton 1 further comprises a top plate 13 which is buckled on the top frame 10, and the top plate 13 is provided with a group of first lifting lugs 14. The top plate 13 can be installed and removed at any time, and is mainly used for verifying different containers. When the top plate 13 is used, it serves as a verification system for a 40' high-volume dry cargo box (40' high-volume dry cargo box is a standard container type commonly used in international shipping, and its core feature is a length of 40 feet and an increased internal space, which is specially designed for transporting goods with large volume and special requirements for vertical space). When the top plate 13 is not used, it serves as a verification system for a 40' open-top box (a special container with no rigid box top at the top, which can load and unload goods through the top, and is suitable for transporting goods with super height, super weight or irregular shape). When the top plate 13 is not used, the goods can be lifted into the container body 15 through the top frame 10 during loading and unloading, which is more convenient for loading. The first lifting lug 14 is used for lifting the top plate 13, and the top plate 13 is buckled above the skeleton 1 by its own weight. This design can expand the types of verification container solutions.

[0031] The outer surface of the skeleton 1 and the outer surface of the side plate 2 are sprayed with a medium phthalo blue finish. This design can prevent the outer surface of the skeleton 1 and the outer surface of the side plate 2 from rusting to some extent.

[0032] In summary, the marine container verification system according to the embodiment of the application uses the skeleton 1 to cooperate with a plurality of unit plates 23 to form the container body 15, and a stress detection device is arranged in the skeleton 1 and the unit plate 23. The adjusting mechanism 3 is arranged at the bottom of the skeleton 1 to drive the container body 15 to swing back and forth, so that the anti-rolling performance of the container body 15 can be detected in inland areas. The anti-rolling performance detection can be performed before the goods are transported, which can to some extent avoid problems of the container during marine transportation, reduce the loss of goods during marine transportation, and predict in advance whether the impact-proof arrangement in the goods is effective, thereby verifying the stability of the container solution for the goods to some extent, avoiding the impact between the goods due to the instability of the container itself when the goods encounter waves, and reducing the probability of possible loss.
