In order to facilitate understanding of the container provided by the embodiment of the present application, first, an application scenario of the container is introduced, and the container provided by the embodiment of the present application is a device for storing and transporting objects, such as cross-sea transportation of various cargoes, so as to facilitate integration and transportation of the cargoes; in addition, containers, such as common energy storage containers, are often used in the energy storage field, that is, a plurality of battery packs are arranged in the container and connected, and the whole energy storage container is used as a whole for temporary or movable energy supply equipment. The embodiment of the application provides a container, improves the quiet bearing strength of container structure, promotes the holistic carrying capacity of container, promotes the security. The following detailed description is made with reference to the specific drawings and examples.

Referring to fig. 1, fig. 1 shows a schematic structural diagram of a container according to an embodiment of the present application. The container provided by the embodiment of the application comprises a frame structure 1 and a plurality of support columns 2, wherein the frame structure 1 comprises a plurality of structural columns 3, and the structural columns 3 are welded and fixed to form the rectangular frame structure 1; the support columns 2 are welded and fixed with the structural columns 3 forming the frame structure 1, so that on one hand, the structural strength of the frame structure 1 is enhanced, the firmness of the container is improved, and on the other hand, the support columns 2 are used as a bearing foundation for placing objects in the container later.

In addition, the outer side of the frame structure 1 is also covered with a protection plate, and a space isolated from the outside is formed by surrounding the inside; during actual use, the type of the protection plate can be adjusted according to actual needs, for example, a door capable of being opened and closed is arranged at a specific position, and details are not repeated in the embodiment of the application.

Referring to fig. 2, the structural columns 3 include a plurality of first structural columns, the support columns 2 include a plurality of first support columns, and the first structural columns and the first support columns are all column structures with cavities or grooves on surfaces, and exemplary first structural columns and the first support columns are common structures such as square tubes, channel steel, i-steel and the like; in this embodiment, the first structural column and the first support column are exemplified as square tubes, wherein the first structural column is welded and fixed with the first support column, and the wall thickness of the first structural column is different from the wall thickness of the first support column.

The container structure is designed by taking the bearing capacity of the container into consideration and limiting the weight of the container. In the container in the prior art, the wall thickness of the selected structural column 3 is the same as that of the support column 2, the structural column 3 and the support column 2 can generate welding deformation when being welded, and the frame structure 1 formed by welding needs to keep the design shape and the size, so that the allowance for the welding deformation of the structural column 3 and the support column 2 is smaller; namely, after the structural columns 3 and the support columns 2 are welded and fixed to form the container, relatively large residual stress exists at the welding position, the welding position can be subjected to plastic deformation in advance under the combined action of the residual stress of the part and the stress generated by external bearing, the problem that the structural strength and the bearing capacity of the container are poor exists, and in order to overcome the problem, the structural strength and the bearing capacity of the structural columns 3 and the support columns 2 need to be increased, namely the wall thickness of the structural columns 3 and the wall thickness of the support columns 2 need to be increased; increasing the wall thickness in turn causes an increase in the weight of the container itself and a greater pressure on the container, and in particular the bottom of the container.

In this application embodiment, set up the wall thickness of first structural column and the wall thickness of first support column different, when carrying out container structural design, comparatively conveniently select corresponding structural dimension according to actual bearing needs and the pressure-bearing requirement at different positions, can reduce container self weight when container reservation sufficient structural strength, bearing capacity. When in actual use, the bearing capacity of the container is stronger, the structure is more stable, the problem that the container is damaged due to insufficient bearing capacity is avoided, and the safety of the container in the processes of carrying goods, transporting, hoisting and the like is improved.

In addition, the container arranged in the embodiment of the application is an energy storage container and further comprises a plurality of battery packs arranged in the frame structure 1; of course, in practice, the number of battery packs is generally two or more.

Referring to fig. 3, for convenience of explanation, the cross-sectional shapes of the first structural columns and the first support columns are compared in parallel, so that the wall thickness and the related dimensional relationship of the first structural columns and the first support columns can be more clearly shown. Illustratively, the first structural column has a wall thickness greater than a wall thickness of the first support column. In the use state of the container, the structural columns 3 forming the frame structure 1 serve as main bearing structures, and the supporting columns 2 are used for supporting cargoes, namely the weight of the loaded cargoes or the weight of the supporting columns 2, and finally act on the structural columns 3, namely the structural columns 3 which are mainly positioned at the bottom and on the vertical sides of the frame structure 1.

Therefore, the wall thickness of the first structural column is larger than that of the first supporting column, the distribution rule of the load in the state of actually bearing the goods is more adapted, the frame structure 1 is guaranteed to have enough structural strength, the stability of the frame structure 1 can be guaranteed in the standing state and the hoisting and transporting processes, the problem that the frame structure 1 is insufficient in strength, deformation and even fracture damage are solved, and the weight of the container is reduced as much as possible under the condition that the container has enough bearing capacity is guaranteed, so that the cost is reduced.

Referring to fig. 3, the wall thickness of the first structural column of the frame structure 1 is set to a and the wall thickness of the first support column is set to b, wherein a and b satisfy the following relationship:

when the wall thickness of the first structural column is too large with the wall thickness of the first supporting column, the problem that the structural strength of the container is inconsistent can be caused, and when the structural strength of the container meets the bearing capacity requirement, the strength of the frame structure 1 can have certain redundancy and certain waste. The ratio of the wall thickness of the first structural column to the wall thickness of the first support column is maintained within a certain range, so that waste can be reduced as much as possible under the condition of meeting the bearing requirement. When the wall thickness difference between the first structural column and the first support column is too small, the wall thicknesses of the first structural column and the first support column are too close, the wall thickness difference is insufficient to relieve larger welding stress caused by limited welding deformation amount, and the problems that the bearing capacity of a container is reduced, the safety of hoisting the container is reduced and the like due to the fact that the larger welding position locally yields in advance to generate plastic deformation risk still exist.
