DETAILED DESCRIPTION

[0019] It is easy to understand that according to the technical scheme of the present application, a person skilled in the art can propose a plurality of structure modes and implementation modes which can be replaced with each other without changing the essential spirit of the present application. Therefore, the following detailed description and the accompanying drawings are only exemplary description of the technical scheme of the present application, and should not be regarded as the whole or regarded as the limitation or restriction of the technical scheme of the present application.

[0020] REFERENCE Figures 1-10 As shown in the figure, the present application provides a technical scheme: a new freight container, including a container body 1 and a hull deck 11, the lower surface of the container body 1 is fixed with a stable assembly 2 for buffering the violent shaking of the container body 1 at the four corner positions, the stable assembly 2 is mainly used to reduce the impact on the container body 1 when the hull shakes violently, when the hull shakes violently, the stable assembly 2 can reduce the shaking amplitude and frequency of the container body 1, so as to reduce the probability of damage to the goods inside the container body 1; The stabilizing component 2 includes two sets of sliding rods 21 symmetrically fixed to the bottom of the container body 1. Each set of sliding rods 21 has an outer tube 22 with an inner cavity filled with magnetorheological fluid at its midpoint. Magnetorheological fluid is a controllable fluid containing magnetic particles. Its rheological properties (such as viscosity and yield stress) are rapidly and reversibly adjusted by applying a magnetic field. Without a magnetic field, the magnetic particles are randomly distributed in the fluid, exhibiting a low-viscosity flow dynamic, i.e., a "free state." When a high-intensity magnetic field is applied, the magnetic particles are oriented along the magnetic field and rapidly transform into a high-rigidity "solid phase." When a medium-intensity magnetic field is applied, it becomes a slowly flowing "ordered phase." This is existing technology and will not be elaborated further. In this case, the substance completely fills the inner cavity of the outer tube 22. When the container body 1 experiences significant swaying along with the ship's hull, the monitoring module promptly detects the excessive amplitude and frequency of the swaying within a short period and sends a signal to the control module. The control module then reduces the current supplied to the electromagnet 221, thereby causing the magnetorheological fluid to enter a slowly flowing "ordered phase." Simultaneously, the two sets of outer tubes 22, affected by the swaying of the container body 1, move laterally in their respective directions. At this time, the various components of the stabilizing assembly 2 operate. Through the magnetorheological fluid (in a slowly flowing "ordered phase") after the application of a magnetic field, and the multi-stage "flow-blocking surface" composed of the spiral block 25, multiple sets of baffles 251, multiple sets of folded plates 261, and multiple sets of rotating plates 263 in the stabilizing assembly 2, the multi-stage "flow-blocking surface"... The "flow surface" increases the contact area with the magnetorheological fluid, thereby increasing the resistance to the lateral movement of the outer tube 22, thus achieving the effect of liquid damping to absorb vibration energy. Both sides of the inner wall of the outer tube 22 are threaded with sealing tubes 23, and the slide rod 21 slides through the two sets of sealing tubes 23. The two sets of sealing tubes 23 and the outer tube 22 together form a sealed movable container. A spiral tube 24 is integrally fixed to the inner wall of the outer tube 22, located in the middle of the two sets of sealing tubes 23. A spiral groove 241 is formed on the inner wall of the spiral tube 24. A spiral block 25 is rotatably installed on the outer wall of the slide rod 21. As the outer tube 22 moves to one side, the spiral groove 241 inside the spiral tube 24 compresses and drives the spiral block 25 to rotate together, and multiple sets of folded plates 261 are subjected to... The spiral block 25 is formed by compression and folding. The outer wall of the spiral block 25 is provided with multiple sets of spiral blades, and the spiral blades are partially embedded in the spiral groove 241. The spiral blades and the spiral groove 241 are slidably connected. Multiple sets of baffles 251 are fixed on the outer wall of the spiral block 25 and between two adjacent sets of spiral blades. Multiple sets of multi-stage slow-flow components 26 are connected to the outer walls of both ends of the spiral block 25 around the axis. When the outer tube 22 moves to one side and the spiral block 25 rotates, the multiple sets of spiral blades on the surface of the spiral block 25 can increase the resistance when the outer tube 22 moves. Similarly, the baffles 251 between the multiple sets of spiral blades can further increase the resistance when the outer tube 22 moves. Finally, the multi-stage slow-flow components 26 are superimposed to achieve multiple buffering of the vibration of the container body 1. The multi-stage slow flow component 26 further comprises a plurality of groups of folded sheets 261 with lengths gradually increasing from close to the spiral block 25 to far away, and adjacent two groups are in a symmetrical relationship, and the two groups of folded sheets 261 are further in a hinged relationship. The outer walls on both sides of the slide rod 21 are slidingly sleeved with a plurality of groups of connecting rings 262, and one end of the outer wall of the connecting ring 262 is hinged to the folded sheet 261. A rectangular through slot is formed in the middle position of the folded sheet 261, and a rotating sheet 263 is rotatably connected to the inner wall of the rectangular through slot. A plurality of electromagnets 221 are embedded in the inner part of the outer tube 22 around the axis.

[0021] Wherein, two groups of folded sheets 261 of the same specification form a pair, and the two groups of folded sheets 261 are hinged to each other and in a symmetrical relationship. A plurality of pairs of folded sheets 261 of different specifications form a plurality of groups of wave-shaped "flow resistance surfaces". Each specification of the folded sheet 261 is a first level of resistance surface. When the outer tube 22 moves to one side, each group of folded sheets 261 is folded due to being pressed, and at the same time, the first spring 27 is pressed and accumulates energy, preparing to drive the folded sheet 261 to reset. At the same time that the folded sheet 261 is folded, each group of rotating sheets 263 rotates inward, i.e., to the side close to the slide rod 21, due to being pressed by the inner walls of the spiral tube 24 and the sealing tube 23, and at the same time, the torsional spring is tightened to accumulate energy, preparing to drive the rotating sheet 263 to reset. A plurality of groups of rotating sheets 263 further increase the contact area with the magnetorheological fluid, and the resistance is increased, further enhancing the shock absorption effect of the device.

[0022] Referring to Figures 4-10 In the embodiment, the outer walls on both sides of each group of outer tubes 22 are throughly provided with internally threaded pipe openings, the outer wall of the sealing tube 23 is provided with threads matching the internally threaded pipe openings, the axes of the two groups of sealing tubes 23 and the outer tubes 22 and the slide rod 21 coincide, a through hole with a matching size is formed at the contact position of the sealing tube 23 and the slide rod 21, and a sealing element is embedded in the inside of the through hole. The spiral tube 24 and the outer tube 22 are of an integrated structure, the spiral tube 24 is fixed at the central position in the inner cavity of the outer tube 22, and the spiral block 25 is rotatably connected to the central position of the slide rod 21.

[0023] Referring to Figures 4-10 In the embodiment, the outer wall of the baffle 251 is provided with a plurality of through holes for the magnetorheological fluid to flow through, the outer wall on one side of the baffle 251 close to the axis of the spiral block 25 is thicker than the other side, and the cross-sectional shape of the baffle 251 is trapezoidal. The outer wall of the baffle 251 is provided with a plurality of through holes for the magnetic fluid to flow through, which can ensure that the magnetic fluid in the "ordered phase" state passes along the through holes, while maintaining a certain resistance, and ensure that the spiral block 25 can slowly move to one side, which has a slow brake effect, effectively absorbs the vibration of the container body 1, and ensures the stability of the container body 1. The cross-sectional shape of the baffle 251 is trapezoidal, which can ensure the stability of the structure of the baffle 251 to a certain extent, and reduce the probability of damage to the baffle 251.

[0024] Referring to Figures 1-10 In the embodiment, the outer wall of the two ends of the slide rod 21 and inside the outer tube 22 is symmetrically provided with a plurality of first springs 27, the two ends of the first spring 27 are respectively fixed to the outer wall of one side of the two groups of connecting rings 262 close to each other, the outer wall of the rotating shaft of the rotating plate 263 is provided with a torsion spring, and the two ends of the torsion spring are respectively fixed to the rotating plate 263 and the inner wall of the rectangular slot; When the plurality of first springs 27 are extruded, they can accumulate power to provide power for the reset of the plurality of folding plates 261. Similarly, the torsion spring can be tightened to accumulate power when the rotating plate 263 is pressed and rotated, and provide power support for the reset of the rotating plate 263. The two groups of slide rods 21 and outer tubes 22 are in a symmetrical relationship, and the two groups of first springs 27 are in a hinged relationship with one group of hinge rods 13. The lower surface of the outer tube 22 is hingedly connected to the hinge rod 13, and the end of the hinge rod 13 away from the outer tube 22 is hingedly connected to the locking block 14. The locking block 14 and the docking sliding block 121 are corresponding connecting components. The upper surface of the ship deck 11 is fixed with a plurality of sliding rails 12 corresponding to the lower surface of the container body 1 at the four corners. The upper surface of each sliding rail 12 is slidably connected to the docking sliding block 121. The outer wall of the docking sliding block 121 is provided with a damping spring 122. The sliding rail 12 and the damping spring 122 can provide a preliminary damping effect for the container body 1.

[0025] Referring to Figures 1-7 In the embodiment, the outer wall of the slide rod 21 is provided with a second spring, and the second spring is fixed to one side away from the two groups of outer tubes 22. The two ends of the slide rod 21 are symmetrically fixed with a fixed seat 211, and the fixed seat 211 is welded to the lower surface of the container body 1. When the outer tube 22 moves to one side and the second spring is extruded or stretched, the second spring can provide assistance for the reset of the movement of the outer tube 22 when the container body 1 is in a relatively stable state. The main material of the slide rod 21 is carbon steel, the main material of the outer tube 22 is aluminum alloy, the surface of the outer tube 22 is coated with a wear-resistant coating, and the inner part of the outer tube 22 is provided with a thermal insulation layer, which can reduce the influence of cold weather on the internal magnetic fluid. The outer wall of the container body 1 is provided with a plurality of monitoring modules for monitoring the shaking degree of the container body 1 in real time, the monitoring modules are connected with the power module and the control module installed on the container body 1 through wires, and the control module intelligently adjusts the current size supplied to the electromagnet 221 by accepting the real-time data of the monitoring modules.

[0026] Working principle: firstly, when the ship is impacted by sea waves and complex ocean currents, the shaking of the ship deck 11 will be transmitted to the sliding rail 12, and the abutting sliding block 121 on the sliding rail 12 cooperates with the damping springs 122 on both sides to provide a preliminary damping effect for the container body 1, thereby reducing the direct transmission of shaking; At the same time, the monitoring module on the outer wall of the container body 1 monitors the shaking degree in real time, and when the shaking amplitude and frequency of the container body 1 within a short time are too large, a signal is sent to the control module in time, and the control module reduces the current size supplied to the electromagnet 221, so that the magnetorheological fluid filled in the inner cavity of the outer tube 22 is in an "ordered phase" that can flow slowly, preparing for subsequent multi-stage buffering; Secondly, in the process of the container body 1 following the ship body shaking, the stabilizing assembly 2 on the lower surface of the container body 1 begins to operate; the outer tube 22 at the middle position of the two groups of sliding rods 21 moves in opposite directions under the influence of shaking, when the outer tube 22 moves, the spiral groove 241 on the inner wall of the spiral tube 24 extrudes the spiral leaves on the outer wall of the spiral block 25, thereby driving the spiral block 25 to rotate on the sliding rod 21; at this time, the spiral leaves on the outer wall of the spiral block 25 and the plurality of baffles 251 between adjacent spiral leaves are in contact with the magnetorheological fluid, and the spiral leaves, the baffles 251 and the through holes on the outer wall thereof in the whole curve shape ensure that the magnetorheological fluid flows slowly while increasing the resistance of the outer tube 22 moving transversely, absorbing the energy of the vibration, which can preliminarily reduce the shaking amplitude and frequency of the container body 1; Thirdly, in the process of the outer tube 22 moving transversely and the spiral block 25 rotating, the plurality of multi-stage slow-flow components 26 at both ends of the spiral block 25 further enhance the buffering effect; the plurality of folding pieces 261 are folded due to extrusion, and the folding pieces 261 of different specifications form a plurality of wave-shaped "flow resistance surfaces" of different sizes, thereby increasing the contact area with the magnetorheological fluid; at the same time, the first springs 27 on the outer walls of the sliding rods 21 are extruded by the connecting rings 262 to accumulate energy, preparing for the resetting of the folding pieces 261; in addition, the rotating pieces 263 at the middle positions of the folding pieces 261 rotate inwardly due to the extrusion of the inner walls of the spiral tube 24 and the sealing tube 23, the torsional springs on the outer walls of the rotating shafts of the rotating pieces 263 are tightened to accumulate energy, and the plurality of rotating pieces 263 further increase the contact area with the magnetorheological fluid, thereby increasing the resistance of the outer tube 22 moving transversely again; The second springs on the outer walls of the sliding rods 21 accumulate energy when being extruded or stretched, and when the container body 1 tends to be stable, the second springs cooperate with the first springs 27 and the torsional springs to drive the resetting of the components; Finally, under the cooperation of the above-mentioned multi-stage "flow resistance surface", i.e. the spiral blade, the baffle 251, the folded blade 261, the rotating blade 263 and the magnetorheological fluid in the "ordered phase", the vibration energy is effectively absorbed through multiple resistances, the shaking amplitude and frequency of the container body 1 are reduced, thereby reducing the probability of damage to the goods inside the container body 1, and reducing the fatigue loss of the container body 1 and the connecting lock.

[0027] The technical scope of the present application is not limited to the above description, and those skilled in the art can make various modifications and changes to the above embodiments without departing from the technical idea of the present application, and these modifications and changes should all belong to the protection scope of the present application.
