Abstract
Description
Technical Field

[0002] With the development of the global economy, containers, as a crucial means of transport in international trade, are increasingly being used in a wide range of fields, and the types of goods transported are also becoming increasingly diverse. Customized, specialized containers are often used to transport various types of specialized cargo. Currently, the most popular method for multimodal transport of liquid cargo is tank containers. However, because commonly used tank containers are cylindrical in shape with butterfly-shaped ends, their internal volume is relatively small compared to rectangular containers of the same length, width, and height, making them difficult to meet the cargo capacity and lightweight requirements of some customers. Therefore, a container is needed that can at least partially address these issues. Utility Model Content

[0064] Unless otherwise stated, numerical ranges herein include not only the entire range between its two endpoints but also the several sub-ranges contained therein.
[0065] The present application provides a container for storing and transporting liquid materials.
[0066] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings.
[0067] like Figure 1 and Figure 2 As shown, in a specific embodiment, the square container 100 according to the present application can be used to store and transport liquid materials. In this application, the container 100 can also be referred to as a square box 100. Under the same length, width and height dimensions, a square box has a larger volume than a round tank container.
[0068] The container 100 comprises a rectangular frame formed by connecting a plurality of beams (two bottom side beams 17A, two top side beams 17B, two bottom end beams 18A, and two top end beams 18B) with four corner posts 10. A roof panel 11, floor panel 12, left side wall 13, right side wall 14, front end wall 15, and rear end wall 16 are mounted to this frame. The roof panel 11 and floor panel 12 are spaced apart along the height direction DH of the container 100. The left side wall 13 and right side wall 14 are spaced apart along the width direction DW of the container 100. The front end wall 15 and rear end wall 16 are spaced apart along the length direction DL of the container 100. The corner posts 10 extend vertically, and the left side wall 13, right side wall 14, front end wall 15, and rear end wall 16 all extend in a vertical plane, giving the container 100 a generally rectangular parallelepiped structure. The roof panel 11, floor panel 12, left side wall 13, right side wall 14, front end wall 15, and rear end wall 16 collectively enclose an interior space 19 of the container 100. The interior space 19 is used to accommodate materials (cargo), particularly liquid materials. The roof 11, floor 12, left side wall 13, right side wall 14, front end wall 15, and rear end wall 16 are also outer walls of the container 100. The left side wall 13, right side wall 14, front end wall 15, and rear end wall 16 are also referred to as walls of the container 100.
[0069] The top panel 11 is provided with a manhole 71 for personnel to pass through, which also serves as a feed inlet (liquid materials flow into the interior space 19 through manhole 71). Manhole 71 is typically covered with a cap. The rear wall 16 is provided with a discharge port (not shown), through which liquid materials flow out of the interior space 19. The discharge port is typically provided with a discharge valve. When the discharge valve is opened, the discharge port is opened. A cap may also be provided at the discharge port 72 to prevent the discharge valve from being accidentally touched. The top panel 11 is also provided with a venting device 70 for ventilating the interior space 19 to the outside environment. The venting device 70 may be, for example, a valve. When the valve is opened, the interior space 19 is connected to the outside environment. To discharge materials, the venting device 70 is first operated to ventilate the interior space 19 to maintain a uniform air pressure. The discharge valve is then opened, allowing air to continuously enter the interior space 19, thereby equalizing the pressure inside and outside the container 100. This prevents deformation of the outer wall of the container 100 due to the pressure imbalance.
[0070] In order to reduce the surge caused by the liquid during transportation, at least one wave-breaking plate 20 is provided inside the container 100. The wave-breaking plate 20 is substantially perpendicular to the longitudinal direction DL of the container 100, that is, substantially parallel to the front and rear end walls. Figure 2 and Figure 4 As shown, the container 100 may include a plurality of wave-breaking panels 20, which are spaced apart along the length direction DL of the container 100. The wave-breaking panels 20 divide the internal space 19 into a plurality of smaller spaces, so that the liquid in the internal space 19 can basically only surge in the smaller spaces between two adjacent wave-breaking panels 20, thereby reducing surges and improving the safety factor.
[0071] The wave-breaking plate 20 may be provided with openings or gaps for people to pass through. Figure 2 and Figure 4 As shown, the wave-breaking plates 20 may also have a gap with the sidewall on the left or right side, forming a gap for personnel to pass through. Each wave-breaking plate 20 corresponds to an opening or gap. Preferably, the openings or gaps corresponding to two adjacent wave-breaking plates 20 are not aligned, or in other words, in the projection along the longitudinal direction DL of the container 100, the openings or gaps corresponding to two adjacent wave-breaking plates 20 do not overlap, to avoid excessive local surges at the openings or gaps.
[0072] In order to reduce the total weight of the container 100 while ensuring the strength of the outer wall, Figures 2 to 4As shown, preferably, at least one of the front and rear end walls (15 and 16) and the left and right side walls (13 and 14) comprises a corrugated sheet 80. The corrugated sheet 80 extends in the vertical direction. Preferably, all of the front and rear end walls (15 and 16) and the left and right side walls (13 and 14) are constructed using the corrugated sheet 80. The two end walls (15 and 16) are supported by two bottom end beams 18A, respectively. The two side walls (13 and 14) are supported by two bottom side beams 17A, respectively. The two bottom end beams 18A and the two bottom side beams 17A can be collectively referred to as the bottom beam of the container 100. Therefore, the corrugated sheet 80 is supported by the bottom beam, or in other words, the bottom of the corrugated sheet 80 is connected to the bottom beam, for example, to the upper surface of the bottom beam. The top of the corrugated sheet 80 is connected to the top beam of the container 100 (for example, the top side beam 17B and / or the top beam 18B), for example, to the lower surface of the top beam.
[0073] like Figure 5 As shown, the corrugated sheet 80 includes a plurality of convex waves 81 and a plurality of concave waves 82, which are arranged alternately. The convex waves 81 and concave waves 82 are also referred to as the waves of the corrugated sheet 80. In this application, the convex waves 81 and concave waves 82 are defined from the perspective of viewing the corrugated sheet 80 from the interior space 19. The portions protruding toward the interior space 19 are convex waves 81, and the portions protruding toward the exterior of the container 100 are concave waves 82. The corrugated sheet 80 has a wavy appearance, including alternating crests 83 and troughs 84, and connecting portions 85 connecting adjacent crests 83 and troughs 84. A crest 83 and its two connecting portions 85 constitute a convex wave 81. A trough 84 and its two connecting portions 85 constitute a concave wave 82. The convex waves 81 and concave waves 82 are arranged in the corrugation width direction DCW. The convex waves 81 and concave waves 82 extend in the corrugation length direction DCL. The corrugated plate 80 has a corrugated depth direction DCD, and preferably, the corrugated width direction DCW, the corrugated length direction DCL, and the corrugated depth direction DCD are perpendicular to each other.
[0074] In order to enhance the strength of the corrugated plate 80, the wave depth DD of at least one wave (convex wave 81 or concave wave 82) of the corrugated plate 80 is greater than 100 mm, for example, greater than or equal to 110 mm. Since the liquid is in a free form, the acceleration and braking during the vehicle's travel will cause the liquid to surge back and forth. When the vehicle is running on a curve, the liquid will surge to one side under the action of centrifugation. The above situations will cause a large impact on the wall of the "transport container", which can easily cause damage to the "transport container" and affect transportation safety. The side panels of existing ordinary dry cargo containers generally adopt a corrugated plate structure with a wave depth of 36 mm, and the side panels of ordinary bulk cargo containers usually adopt a corrugated plate structure with a wave depth of 48-60 mm. For the transportation of liquid cargo, ordinary dry cargo containers and ordinary bulk cargo containers do not have the load-bearing capacity required to transport liquid cargo. The present application improves the strength of the corrugated plate by increasing the wave depth of the corrugated plate, thereby making the square box suitable for transporting liquids.
[0075] Furthermore, at locations where the corrugated sheet 80 has a corrugated depth greater than 100 mm, the sheet thickness DT is greater than or equal to 2.6 mm, for example, greater than or equal to 2.6 mm and less than or equal to 4 mm. Thus, the strength of the corrugated sheet 80 is ensured by the coordination of corrugated depth and sheet thickness. In this application, while increasing the corrugated depth, rationally controlling the sheet thickness can avoid significantly increasing the weight of the box, reduce the load capacity, and thus avoid increasing transportation costs. Furthermore, as sheet thickness increases, the profiling process becomes more difficult, and is more susceptible to cracking, making it difficult to ensure quality.
[0076] The at least one corrugated plate 80 having a corrugated depth greater than 100 mm may be a corrugated plate 80 in any one of the front wall 15, rear wall 16, left wall 13, and right wall 14. Preferably, each of the front wall 15, rear wall 16, left wall 13, and right wall 14 includes at least one corrugated plate 80 that meets the dual requirements of the corrugated plate depth DD and plate thickness DT.
[0077] Preferably, the corrugated plate 80 has a corrugated depth greater than 100 mm, for example greater than or equal to 110 mm. Further, the corrugated plate 80 has a thickness DT greater than or equal to 2.6 mm, for example greater than or equal to 2.6 mm and less than or equal to 4 mm.
[0078] All corrugated sheets 80 of the container 100 can be made of uniform specifications, or they can be spliced together using corrugated sheets 80 of different specifications. For example, while ensuring strength, corrugated sheets 80 of different corrugated depths, thicknesses, and waveforms can be used to splice together the outer wall to achieve the goals of reducing weight, lowering costs, and reducing process steps. For example, the corrugated sheets 80 include a first corrugated sheet and a second corrugated sheet, and the first corrugated sheet and the second corrugated sheet differ in at least one of the following: corrugated depth, sheet thickness, and waveform. The outer walls of different sides of the container 100 respectively use the first corrugated sheet and the second corrugated sheet; alternatively, the outer wall of the container 100 on the same side is formed by splicing the first corrugated sheet and the second corrugated sheet, for example, the first corrugated sheet and the second corrugated sheet are spliced together in an alternating arrangement.
[0079] For example, the corrugated sheet 80 used for the end wall (15 or 16) may have the same or different specifications as the corrugated sheet 80 used for the side wall (13 or 14). Specifically, the wave depth DD of the corrugated sheet 80 used for the end wall (15 or 16) may have the same or different specifications as the corrugated sheet 80 used for the side wall (13 or 14). Alternatively, the wave shape of the corrugated sheet 80 used for the end wall (15 or 16) may have the same or different specifications as the corrugated sheet 80 used for the side wall (13 or 14). Alternatively, the sheet thickness DT of the corrugated sheet 80 used for the end wall (15 or 16) may have the same or different specifications as the sheet thickness DT of the corrugated sheet 80 used for the side wall (13 or 14). For example, the wave depth DD of the corrugated sheet 80 used for the end wall (15 or 16) may be greater than the wave depth DD of the corrugated sheet 80 used for the side wall (13 or 14). For another example, the plate thickness DT of the corrugated plate 80 used for the end wall (15 or 16) is greater than the plate thickness DT of the corrugated plate 80 used for the side wall (13 or 14).
[0080] The same end wall (15 or 16) can be made of corrugated sheets of uniform specifications or by splicing together corrugated sheets of different specifications. Therefore, the corrugated sheets 80 used in the same end wall can have the same or different wave depths DD, the same or different thicknesses DT, and the same or different wave shapes.
[0081] Similarly, the same side wall (13 or 14) can be made of corrugated sheets of uniform specifications or by splicing corrugated sheets of different specifications. Therefore, the corrugated sheets 80 used in the same side wall can have the same or different wave depths DD, the same or different thicknesses DT, and the same or different wave shapes.
[0082] The wave-breaking plate 20 can also be made of the corrugated plate 80 to further unify the material of the container 100. When used as a wave-breaking plate, the corrugated length direction DCL of the corrugated plate 80 can be in the up-down direction (see Figure 2 ), or it can be left or right.
[0083] In the cross section of the corrugated plate 80 (the cross section perpendicular to the corrugation length direction DCL), the planar dimensions of the convex wave 81 and the concave wave 82 of the corrugated plate 80 can be the same or different. In other words, the cross section of the convex wave 81 and the cross section of the concave wave 82 can be congruent or not. For example, the convex wave 81 and the concave wave 82 have different shapes. For example, one of the crest portion 83 and the trough portion 84 is constructed as an arc, while the other is constructed as a straight line. Alternatively, the convex wave 81 and the concave wave 82 have different widths. Figure 5 As shown, the width of the convex wave 81 is smaller than the width of the concave wave 82. Those skilled in the art can also configure the convex wave 81 and the concave wave 82 to have different planar dimensions in other ways.
[0084] The corrugated plate 80 can have different wave shapes. For example, the cross section of the wave can be a serpentine curve or a broken line. Figure 5 In the illustrated zigzag-line embodiment, the peaks 83, troughs 84, and connecting portions 85 are all generally flat. That is, in the projection of the corrugated plate 80 along the corrugation length direction DCL (that is, in a cross-section of the corrugated plate 80 perpendicular to the corrugation length direction DCL), the peaks 83, troughs 84, and connecting portions 85 all extend at least partially along straight lines (representing straight line segments). Thus, both the convex waves 81 and the concave waves 82 are C-shaped zigzag lines.
[0085] For example, in a cross-section of the corrugated plate 80 perpendicular to the corrugation length direction DCL, at least a portion of the peaks 83 is configured to extend along a first straight line L1, at least a portion of the troughs 84 is configured to extend along a second straight line L2, and at least a portion of the connecting portion 85 is configured to extend along a third straight line L3. Preferably, the peaks 83 are generally configured to extend along the first straight line L1, the troughs 84 are generally configured to extend along the second straight line L2, and the connecting portion 85 is generally configured to extend along the third straight line L3. Here, "generally configured to extend along a straight line" means that the remainder of the component, excluding the portions at its ends that connect to other components, extends along a straight line. The portions at its ends that connect to other components are, for example, rounded corners. In other words, the peaks 83, troughs 84, and connecting portions 85 ideally extend along straight lines, but for manufacturing considerations, the connecting portions between them are rounded corners.
[0086] Preferably, the first straight line L1 of the peak portion 83 and the second straight line L2 of the trough portion 84 are parallel to each other.
[0087] The third straight line L3 of the connecting portion 85 does not intersect the first straight line L1 of the crest portion 83 at a right angle. The third straight line L3 of the connecting portion 85 does not intersect the second straight line L2 of the trough portion 84 at a right angle. The angle α1 between the third straight line L3 of the connecting portion 85 and the first straight line L1 of the crest portion 83 within the convex wave 81 is an obtuse angle. The angle α2 between the third straight line L3 of the connecting portion 85 and the second straight line L2 of the trough portion 84 within the concave wave 82 is an obtuse angle. The inclined arrangement of the connecting portion 85 improves the load-bearing capacity of the corrugated sheet 80 and also makes it easier to process.
[0088] Preferably, the width of the portion of the trough portion 84 extending along the second straight line L2 is in the range of [100, 400] mm. Preferably, the width of the portion of the crest portion 83 extending along the first straight line L1 is in the range of [100, 400] mm. The width of the straight portion of the trough portion 84 may be the same as or different from the width of the straight portion of the adjacent crest portion 83. Preferably, in the projection of the corrugated plate 80 along the corrugation length direction DCL, the length W1 of the projection of the connecting portion 85 on the first straight line L1 of the crest portion 83 is not less than 15 mm. Preferably, in the projection of the corrugated plate 80 along the corrugation length direction DCL, the length W2 of the projection of the connecting portion 85 on the second straight line L2 of the trough portion 84 is not less than 15 mm.
[0089] Preferably, the convex wave 81 has an axisymmetric structure symmetrical about an axis of symmetry extending in the corrugation depth direction DCD. Preferably, the concave wave 82 has an axisymmetric structure symmetrical about an axis of symmetry extending in the corrugation depth direction DCD.
[0090] Preferably, the corrugated plate 80 is constructed so that within a width of 1m, the corrugated plate 80 includes at least one convex wave 81 and at least one concave wave 82. That is, the distance between the corresponding positions of two adjacent convex waves 81 does not exceed 1m, and the distance between the corresponding positions of two adjacent concave waves 82 does not exceed 1m. The width of the crest portion 83 and the inclination of the connecting portion 85 determine the width of the convex wave 81. The width of the trough portion 84 and the inclination of the connecting portion 85 determine the width of the concave wave 82. In the present application, the convex wave 81 and the concave wave 82 have appropriate widths. If the wave width is too large, the strength of the corrugated plate 80 cannot be guaranteed. If the wave width is too small, the material consumption will increase, the cost will increase, and the volume of the internal space 19 will be reduced.
[0091] Table 1 compares the moments of inertia of areas for containers using corrugated sheeting with different corrugated sheeting depths. Container No. 1 is a standard dry cargo container (36mm corrugated sheeting depth), Container No. 2 is a bulk cargo container (50mm corrugated sheeting depth), Container No. 3 is a bulk cargo container (60mm corrugated sheeting depth), Container No. 4 is a liquid container (100mm corrugated sheeting depth), and Container No. 5 is a liquid container (110mm corrugated sheeting depth).
[0092] Table 1 Comparison of the section inertia moments of containers using corrugated sheets with different wave depths
[0093]
[0094] As can be seen from Table 1, the deeper the wave depth, the greater the section moment of inertia, and the corresponding bending stiffness (bending stiffness is the product of section moment of inertia and elastic modulus) will also be higher. When the wave depth of the corrugated plate reaches 100mm, the section moment of inertia can reach 75.9×10 5 (mm 4 ), which can well meet the needs of loading liquids. In addition, by increasing the wave depth, the number of waves in a single plate (for example, a plate width of 1116mm) can be reduced while still meeting strength requirements, thereby saving materials and improving production efficiency while meeting lightweight design requirements.
[0095] This application provides a wall panel corrugated design that meets strength requirements. By designing the wave depth of the corrugated plate to be greater than 100mm, the strength of the corrugated plate can meet the requirements of liquid transportation, thereby breaking through the traditional method of using tank containers to transport liquids, so that square containers can also transport liquids, giving full play to the advantages of large volume, and being able to load more liquids at a time, reducing logistics costs, saving transportation resources, and reducing carbon emissions. On the basis of ensuring the wave depth, the outer wall of the container can be equipped with reinforcing beams to avoid increasing the difficulty of the box processing technology and increasing the production and manufacturing costs, which reduces the manufacturing difficulty and production costs to a certain extent. At the same time, it avoids increasing the dead weight of the box and affecting the cargo loading capacity.
[0096] The processes and steps described in all the preferred embodiments described above are merely examples. Unless adverse effects occur, various processing operations may be performed in a different order from the above process. The order of the steps in the above process may also be increased, combined, or deleted according to actual needs.
