Description

Technical Field

[0001] The utility model relates to the technical field of energy storage devices, in particular to an energy storage box structure. Background Technique

[0002] With the rapid development of photovoltaic and battery technologies in recent years, the energy storage carrier has developed from a storage battery to a lithium battery with a high-performance charge and discharge rate. The protection and storage platform of the energy storage carrier has been replaced by an energy storage container with high protection and convenient movement advantages instead of the original fixed building structure. The installation and transportation of large-scale energy storage systems have relatively special requirements for space and use sites. In a limited space, it is necessary to place energy storage batteries as much as possible to improve space utilization. During the use of the current energy storage container, the battery pack is often placed flat on the bracket to achieve the space utilization of the energy storage battery.

[0003] The utility model with the publication number of CN220569811U discloses an energy storage container. The cold air inside the container body is connected to the air guide pipe on the side of the battery box through a pipeline to cool the battery inside the battery box; a fixed seat is fixed at the front end of the inner side of the mounting frame, and a first inclined surface is arranged inside it. The front parts on both sides of the battery box are movably connected with rotating connectors; when the battery box is pushed forward along the guide rail, the rotating connector contacts the first inclined surface, causing the rotating connector to rotate towards the side of the battery box until the battery box continues to be pushed forward along the guide rail, and the rotating connector rotates to the front of the fixed seat under the elastic force of its own elastic piece, and the rotating connector and the fixed seat are snap-connected through a snap-fastening member to form the fixation of the battery box. However, when this utility model is in use, when a thermal runaway occurs in a certain battery pack in the energy storage container, the high-temperature and high-pressure substances ejected from the battery pack may be sprayed to other energy storage positions in the energy storage container, causing thermal runaway of the battery packs in other positions, and then leading to a chain out-of-control of each energy storage position in the energy storage container, endangering the safety of the entire energy storage container, and the safety performance is insufficient. Therefore, it is very necessary to design an energy storage box structure with strong practicability and good safety. Content of the Utility Model

The energy storage carrier battery pack 1 is placed through the placement area. When the battery pack 1 is placed, it is docked and placed through the slide rail 5. The battery pack 1 is limited by the positioning circular plate 6 at the rear end.

[0026] Working principle: When the utility model is in use, components such as the battery pack 1, the fixing frame 2, the first connecting beam 3, and the second connecting beam 4 together form an energy storage box, which has a firm and stable structure. Through the arranged bottom plate 13, hydraulic cylinder 15, lifting plate 16, and moving wheels 17, the energy storage box can be conveniently shifted, facilitating the placement of the battery pack 1. Through the arranged docking blocks 22 and docking grooves 21, the energy storage boxes can be arranged in sequence, increasing the stability of the placement of the energy storage box. The energy storage carrier battery pack 1 is placed through the placement area. When the battery pack 1 is placed, it is docked and placed through the slide rail 5, and the battery pack 1 is limited by the positioning circular plate 6 at the rear end. The support plates 8 are symmetrically arranged at the lower end of the battery pack 1, further increasing the stability of the placement of the battery pack 1.

The signal is transmitted to the external control terminal, and when the control terminal receives the signal, the control valve 12 is opened, and fire extinguishing is carried out with the fire extinguishing medium in the fire extinguisher 11. At the same time, since the fire protection plates 7 are evenly distributed with fire ports 9 at the upper and lower ends, the adjacent battery packs 1 can be timely isolated from the fire to prevent the fire from spreading further, and subsequent fire extinguishing and other subsequent treatments are carried out manually. The upper end surface of the fire protection plate 7 is slightly lower than the upper end surface of the support plate 8, so that there is a certain gap between the upper end of the fire protection plate 7 and the battery plate 1, facilitating the ejection of the fire extinguishing medium to carry out fire extinguishing on the battery plate 1. The positioning circular plate 6 is sealed by the sealing cover 19, playing a role in protecting and dust-proofing the internal fire extinguisher 11. Through the setting of the annular cover 18, good dust-proof protection can be provided for the hydraulic cylinder 15, the lifting plate 16, and the moving wheels 17, extending their service life.
