DETAILED DESCRIPTION

[0034] 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.

[0035] Reference Figures 1-10The application provides a novel freight container, which comprises a container body 1 and a ship deck 11, and the lower surface of the container body 1 is fixed with a stabilizing assembly 2 at the four corners, which is used for buffering the violent shaking of the container body 1; the stabilizing assembly 2 is mainly used for reducing the influence of the violent shaking of the ship on the container body 1; when the ship shakes violently, the stabilizing assembly 2 can reduce the shaking amplitude and frequency of the container body 1, so that the damage probability of the goods in the container body 1 is reduced.

[0036] The stabilizing assembly 2 comprises two groups of slide rods 21 symmetrically fixed at the bottom of the container body 1, and outer tubes 22 filled with magnetorheological fluid are sleeved at the middle positions of the two groups of slide rods 21. The magnetorheological fluid is a kind of controllable fluid containing magnetic particles, and the rheological properties (such as viscosity and yield stress) of the magnetorheological fluid can be quickly and reversibly adjusted by applying a magnetic field. When there is no magnetic field, the magnetic particles are randomly distributed in the carrier liquid, the magnetorheological fluid is in a low-viscosity flow state (i.e. "free state"), and when a high-intensity magnetic field is applied, the magnetic particles are oriented into chains along the magnetic field, and the magnetorheological fluid is quickly changed into a high-rigidity "solid state". When a medium-intensity magnetic field is applied, the magnetorheological fluid is in a slowly flowing "ordered phase". This is the prior art, and therefore will not be described in detail. In the present case, the substance completely fills the inner cavities of the outer tubes 22. When the container body 1 undergoes a large amplitude of shaking along with the ship body, the monitoring module senses that the amplitude and frequency of the shaking of the container body 1 are too large in a short time, and timely sends a signal to the control module, which in turn reduces the current supplied to the electromagnet 221, so as to make the magnetorheological fluid in a slowly flowing "ordered phase". At the same time, the two groups of outer tubes 22 are affected by the shaking of the container body 1 and move in opposite directions. At this time, the components of the stabilizing assembly 2 are operated, and the magnetorheological fluid (in a slowly flowing "ordered phase") after the magnetic field is applied cooperates with the multi-stage "flow resistance surface" composed of the spiral block 25, the groups of baffle plates 251, the groups of folding plates 261 and the groups of rotating plates 263 in the stabilizing assembly 2. The multi-stage "flow resistance surface" increases the contact surface with the magnetorheological fluid, thereby increasing the resistance of the outer tube 22 to move in the transverse direction. In this way, the effect of liquid damping to absorb vibration energy is achieved. The inner walls of the outer tube 22 at both sides are threadedly connected with sealing tubes 23, and the slide rods 21 slide through the two groups of sealing tubes 23. The two groups of sealing tubes 23 and the outer tube 22 together form a sealed movable container. The inner wall of the outer tube 22 and located at the middle position between the two groups of sealing tubes 23 is integrally fixed with a spiral tube 24. The inner wall of the spiral tube 24 is provided with a spiral groove 241. The outer wall of the slide rod 21 is rotatably connected with the spiral block 25. When the outer tube 22 moves to one side, the spiral groove 241 inside the spiral tube 24 extrudes and drives the spiral block 25 to rotate, and the groups of folding plates 261 are extruded and folded to form groups. The outer wall of the spiral block 25 is provided with groups of spiral leaves, and the spiral leaves are partially embedded in the inner part of the spiral groove 241. The spiral leaves and the spiral groove 241 are in sliding connection. The outer wall of the spiral block 25 and located between adjacent groups of spiral leaves is fixed with groups of baffle plates 251. The outer walls of both ends of the spiral block 25 are rotatably connected with groups of multi-stage flow slowing components 26. When the outer tube 22 moves to one side and the spiral block 25 rotates, the groups of spiral leaves on the surface of the spiral block 25 can increase the resistance of the outer tube 22 when moving. Similarly, the baffle plates 251 between the groups of spiral leaves can further increase the resistance of the outer tube 22 when moving. Finally, the multi-stage flow slowing components 26 are stacked and cooperated to realize multiple buffering of the shaking of the container body 1.

[0037] 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 of 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.

[0038] A plurality of electromagnets 221 are embedded in the inner part of the outer tube 22 around the axis.

[0039] 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.

[0040] 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.

[0041] Referring to Figures 4-10 In the embodiment, as shown in the drawings, the outer walls of 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 tube 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.

[0042] 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.

[0043] Referring to Figures 4-10 In the embodiment, as shown in the drawings, 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 of the side close to the axis of the spiral block 25 of the baffle 251 is thicker than the other side, and the cross-sectional shape of the baffle 251 is trapezoidal.

[0044] 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.

[0045] 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 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 fixed to the rotating plate 263 and the inner wall of the rectangular slot;

[0046] 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 store power when the rotating plate 263 is pressed and rotated, and provide power support for the reset of the rotating plate 263.

[0047] 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 a 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 abutting sliding block 121 are corresponding connecting components.

[0048] The upper surface of the hull 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 abutting sliding block 121. The outer wall of the abutting 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.

[0049] 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.

[0050] 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.

[0051] The main body of the slide bar 21 is made of carbon steel, the main body of the outer tube 22 is made of 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 heat preservation interlayer, which can reduce the influence of cold weather on the internal magnetorheological fluid;

[0052] 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 receiving real-time data of the monitoring modules.

[0053] Working principle: first, 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 to the container body 1, reducing the direct transmission of shaking;

[0054] 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, the control module is signaled 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;

[0055] 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 slide bars 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 pipe 24 extrudes the spiral leaves on the outer wall of the spiral block 25, thereby driving the spiral block 25 to rotate on the slide bar 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, the spiral leaves, the baffles 251 and the through holes on the outer wall thereof in the whole are in a curved shape, which ensures the slow passage of the magnetorheological fluid while increasing the resistance of the outer tube 22 moving horizontally, absorbing the energy of the vibration, and can preliminarily reduce the shaking amplitude and frequency of the container body 1;

[0056] Again, in the process of the lateral movement of the outer tube 22 and the rotation of the spiral block 25, the groups of multi-stage slow-flow components 26 at both ends of the spiral block 25 further enhance the buffering effect; the groups of folding sheets 261 are folded due to the extrusion, and the folding sheets 261 of different specifications constitute groups of wave-shaped "flow resistance surfaces" of different sizes, increasing the contact area with the magnetorheological fluid; at the same time, the first springs 27 on the outer walls of both sides of the slide rod 21 are extruded by the connecting rings 262 to accumulate energy, preparing for the resetting of the folding sheets 261; in addition, the rotating sheets 263 at the middle positions of the folding sheets 261 rotate inward due to the extrusion of the inner walls of the spiral tube 24 and the sealing tube 23, and the torsional springs on the outer walls of the rotating shafts of the rotating sheets 263 are tightened to accumulate energy, and the groups of rotating sheets 263 further increase the contact area with the magnetorheological fluid, so that the resistance to the lateral movement of the outer tube 22 is increased again.

[0057] When the container body 1 tends to be stable, the second springs on the outer walls of the slide rod 21 are extruded or stretched to accumulate energy, and cooperate with the first springs 27 and the torsional springs to drive the resetting of each component.

[0058] Finally, in the cooperation of the above-mentioned multi-stage "flow resistance surfaces", i.e. the spiral leaves, the baffles 251, the folding sheets 261, and the rotating sheets 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, the probability of damage to the goods in the container body 1 is reduced, and the fatigue loss of the container body 1 and the connecting lock is reduced.

[0059] 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 be within the protection scope of the present application.
