Description

Technical Field

[0001] The present invention relates to the field of battery module loading and unloading, and in particular to a method for loading and unloading a battery module in a complex and narrow space. Background Art

[0002] With the continuous advancement of large-scale underwater product technology, battery systems are increasingly used in underwater products. As a key component of energy supply, batteries undertake vital tasks. In order to meet the long-term and efficient operation and operation requirements of large-scale underwater products, battery systems are usually composed of multiple battery modules. The above battery modules need to be precisely installed, connected and fixed through a special assembly platform. If a battery module fails, it needs to be uninstalled.

[0003] Due to the small internal space of underwater products, the design of battery cabinets (which are used to assemble battery modules) needs to make efficient use of limited space. The narrow space and the particularity of the underwater operating environment (such as moisture, high pressure, etc.) increase the difficulty and risk of loading and unloading battery modules. At present, conventional battery module loading and unloading methods generally use electric forklifts, ground bulls, electric tractors, stackers and other equipment. The above equipment has certain mobility and adjustment functions, but when performing precise assembly inside the narrow battery cabinet, it is difficult to adapt to its complex spatial layout and special operating requirements, making it difficult to effectively ensure the precise installation and safe operation of the battery modules. The defects of traditional assembly equipment are mainly reflected in the following aspects:

[0004] (1) Lack of flexibility and precision

[0005] When loading and unloading battery modules, existing electric forklifts, stackers and other handling equipment cannot provide precise positioning and height adjustment, making the loading and unloading operations difficult and prone to errors.

[0006] (2) Poor adaptability, unable to meet the needs of small spaces

[0007] Traditional loading and unloading equipment is mostly fixed or large in design with limited operating space. Its adjustability and mobility are low, which affects assembly efficiency and operational convenience.

[0008] (3) Poor stability and lack of side protection devices

[0009] The marine environment is harsh, and flow loads can cause underwater products to move in six degrees of freedom. Traditional loading and unloading equipment lacks anti-slip devices for battery modules, which can easily cause battery modules to fall during assembly, resulting in safety accidents. Summary of the invention

[0010] The present invention provides a method for loading and unloading a battery module in a complex and narrow space, including two states of battery module assembly and disassembly, taking into account adjustability, flexibility, adaptability and stability.
