Description

Technical Field

[0001] The utility model relates to a battery rack for a marine container - type energy - storage battery cabin, belonging to the technical field of energy - storage batteries. Background Art

[0002] In a complex marine transportation environment, the energy - storage battery cabin often faces severe bumps and vibrations, which pose extremely high requirements for the structural strength of the battery rack inside the battery cabin and the fixing method of the battery module.

[0003] Currently, the battery racks of existing energy - storage battery cabins on the market generally lack an effective guiding mechanism. As a result, during the installation process of the battery module, the battery module is prone to unnecessary collisions or interferences with the battery rack, which not only increases the installation difficulty but also may cause physical damage to the battery module and the battery rack. At the same time, due to the lack of precise guidance, the battery module is often difficult to be accurately positioned, thus affecting the matching effect of the subsequent limiting device and reducing the stability and safety of the entire battery cabin.

[0004] In addition, the battery racks of existing energy - storage battery cabins lack a reliable limiting mechanism, which means that under strong vibrations or impacts, the battery module may shift or fall off. This will not only damage the battery module itself but also may trigger a series of chain reactions, such as system thermal runaway, fire, or even explosion and other serious consequences. Once such an accident occurs, it will not only cause huge economic losses but also pose a serious threat to personal safety. Summary of the Utility Model

[0007] A side - edge limit block is fixedly installed on the inner wall of each column, and each side - edge limit block is located above the corresponding guide rail.

[0008] Each side - edge limit block is made of self - lubricating nylon material.

[0009] A wedge - shaped surface is provided at the rear end of each side - edge limit block.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] A battery rack for a marine container - type energy storage battery compartment, comprising columns 11, guide rails 12, front end limiters 14 and rear end limiters 15; a plurality of the columns 11 are arranged in a double - row rectangular array. The inner sides of the plurality of columns 11 in the same row are fixedly connected to the correspondingly horizontally arranged guide rails 12 by self - tapping screws. Before connection, the self - tapping screw fastening holes are pre - machined, which can effectively improve the assembly accuracy of the columns 11 and the guide rails 12. The two guide rails 12 are correspondingly arranged. A front end limiter 14 is welded and fixed at the front end of each guide rail 12. Welding holes are reserved before combination to improve the welding positioning accuracy and welding strength. A rear end limiter 15 is provided at the rear end of each guide rail 12.

[0022] On the inner wall of each column 11, a side - side limit block 13 is fixed by screws. Threaded holes are pre - machined on the columns 11 to improve the assembly accuracy of the side - side limit blocks 13 and the columns 11 and reduce the maintenance difficulty. The threaded holes are countersunk holes, and the threaded holes are over - designed to prevent the screws from protruding due to wear of the side - side limit blocks 13 and scratching the battery module 2. Each side - side limit block 13 is located at the upper end of the corresponding guide rail 12, and a plurality of side - side limit blocks 13 are arranged in one - to - one correspondence; the side - side limit blocks 13 can effectively reduce the X - direction shaking amplitude of the battery module 2 in the battery rack 1 and improve the installation accuracy of the battery module 2.

[0023] Each side - side limit block 13 is made of self - lubricating nylon material.
