Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a lithium battery energy storage cabinet that is easy to install with a large cover plate. Background Technology

[0002] A lithium battery energy storage cabinet is a standardized energy storage device that integrates lithium-ion battery modules, a battery management system (BMS), a thermal management system, and a safety protection structure. It is mainly used in scenarios such as grid peak shaving and frequency regulation, new energy consumption, and industrial and commercial backup power.

[0003] The large cover plate of the energy storage cabinet is a core structural component covering the side of the energy storage battery cabinet. It primarily serves functions such as sealing and protection, thermal management, electrical connection, and structural support. Its design directly affects the safety, heat dissipation efficiency, and lifespan of the battery system. The bottom of the large cover plate engages with threaded holes on the bottom plate of the energy storage battery cabinet, and is locked in place by bolts. Simultaneously, the side surface of the large cover plate is also connected and fixed to the side surface of the energy storage cabinet by bolts. This securely locks the large cover plate to the side of the energy storage cabinet, protecting the cabinet and the lithium batteries inside.

[0004] Although the existing technologies mentioned above can solve the corresponding technical problems, they still have certain drawbacks: When installing the large cover plate of the existing energy storage cabinet, the energy storage cabinet needs to be erected and the threaded holes on its base plate need to be aligned with the threaded holes on the bottom of the large cover plate before the bolts are tightened. However, when aligning the threaded holes, the operator needs to bend down and observe carefully to align the threaded holes of the large cover plate with the threaded holes of the energy storage cabinet base plate. This takes a long time, and the large cover plate is heavy, which makes aligning the threaded holes difficult and physically demanding. It is easy for the operator to misalign due to insufficient physical strength, making it difficult to tighten the bolts properly. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings and deficiencies of the existing technology by providing a lithium battery energy storage cabinet with convenient large cover plate installation, which allows for easy cover plate installation and quick cover plate positioning.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a lithium battery energy storage cabinet that facilitates the installation of a large cover plate, comprising a cabinet body and a base plate fixedly installed at the bottom of the cabinet body. The base plate is provided with a connecting plate having a plurality of threaded holes for connecting plates. A cover plate is fixed to one side of the cabinet body by bolts, and the bottom surface of the cover plate is fixedly connected to the connecting plate by bolts. The bottom surface of the cover plate is integrally formed with a plurality of threaded holes for cover plates. A quick positioning device that passes through the threaded holes of the cover plate and the threaded holes of the connecting plate is detachably installed on the bottom surface of the connecting plate. One side of the connecting plate is in contact with the outer surface of the cover plate.

[0007] A further improvement is that a cabinet door is movable and latched on one side of the cabinet.

[0008] A further improvement is that the quick positioning device includes a bonding plate that is attached to the outer surface of the cover plate on one side and a lower extension plate that is fixedly set at the bottom end of the bonding plate. Several positioning posts are fixedly provided on the upper surface of the lower extension plate. The positioning posts extend upward through the threaded holes of the cover plate and the threaded holes of the connecting plate and can be detachably installed on the bottom surface of the connecting plate.

[0009] A further improvement is that a side extension plate is fixedly provided on the other side of the bonding plate, and a handle is provided on the side of the side extension plate.

[0010] After adopting the above technical solution, the beneficial effects of this utility model are as follows: When installing the cover plate, the quick positioning device can be inserted first through the threaded hole of the connecting plate at the bottom of the connecting plate, so that the positioning pin of the quick positioning device passes through the threaded hole of the connecting plate, and the lower extension plate is attached to the lower surface of the connecting plate. Then the cover plate can be lifted and moved downwards along the side of the cabinet. During the downward movement, if there is no resistance, the threaded hole of the cover plate can pass directly through the positioning pin. If there is resistance, it can be moved slightly laterally so that the threaded hole of the cover plate passes through the positioning pin. At this time, the remaining threaded holes of the cover plate and the threaded holes of the connecting plate that are not penetrated by the positioning pin can be aligned. At this time, the bolts can be quickly screwed into the remaining threaded holes of the cover plate and the threaded holes of the connecting plate. The positioning is fast and accurate, making the installation of the cover plate more convenient. Attached Figure Description

Detailed Implementation

[0013] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0014] See Figure 1-6 As shown, the technical solution adopted in this specific embodiment is: a lithium battery energy storage cabinet that facilitates the installation of a large cover plate, including a cabinet body 1 and a base plate 3 fixedly installed at the bottom of the cabinet body 1. The base plate 3 is provided with a connecting plate 31 having a plurality of threaded holes for connecting plates. A cover plate 4 is fixed to one side of the cabinet body 1 by bolts, and the bottom surface of the cover plate 4 is fixedly connected to the connecting plate 31 by bolts. The bottom surface of the cover plate 4 is integrally formed with a plurality of threaded holes for the cover plate. A quick positioning device 5 is detachably installed on the bottom surface of the connecting plate 31, passing through the threaded holes of the cover plate and the threaded holes of the connecting plate. One side of the connecting plate 31 is attached to the outer surface of the cover plate 4. The quick positioning device 5 includes: A bonding plate 51 is attached to the outer surface of the cover plate 4 on one side, and a lower extension plate 52 is fixedly installed at the bottom end of the bonding plate 51. Several positioning posts 53 are fixedly provided on the upper surface of the lower extension plate 52. The positioning posts 53 extend upward through the threaded holes of the cover plate and the threaded holes of the connecting plate and are detachably installed on the bottom surface of the connecting plate 31. When in use, the battery is inserted into the cabinet 1, and the bottom plate 3 supports the cabinet 1. At the same time, the connecting plate 31 on the bottom plate 3 has multiple threaded holes. After the battery is inserted, the cover plate 4 needs to be installed on the side of the cabinet 1. The bottom surface of the cover plate 4 has multiple threaded holes.
