Description

Technical Field

[0001] The utility model relates to the technical field of battery racks, in particular to a battery rack. Background Art

[0002] Currently, most battery racks used in container energy storage projects are integrated welded structures. This is because the welded structure has high connection strength, the battery rack has good overall rigidity, and it can be used permanently after being installed or welded once inside the container. Therefore, it is widely used in container energy storage projects.

[0027] Please refer to Figures 1 to 3As shown, the utility model proposes a battery rack 100 for placing batteries indoors, and the battery rack 100 includes at least one group of frame components 1, and the frame component 1 includes a first frame 11, a second frame 12 and a connecting cross piece. The first frame 11 and the second frame 12 are both provided with a battery layer support 15 and a battery fixing bar 16. The first frame 11 and the second frame 12 are detachably connected through the connecting cross piece, and the fixing holes are used to fix the batteries; wherein, the frame component 1 has a disassembled state and a combined state. In the combined state, the battery layer support 15, the battery fixing bar 16, the first frame 11 and the second frame 12 enclose a placement space for placing batteries.

[0028] In this embodiment, when the rack assembly 1 is in a disassembled state, the first frame 11, the second frame 12, and the connecting crossbar are in a separated state. The first frame 11, the second frame 12, and the connecting crossbar can be moved by a person or a trolley. In this way, the rack assembly 1 can be transported into the room through the door frame. After the rack assembly 1 is transported into the room, the first frame 11 and the second frame 12 are connected by the connecting crossbar, so that the rack is in an assembled state. The battery layer tray 15, the battery fixing frame, the first frame 11, and the second frame 12 enclose a placement space for placing batteries. When the battery is placed in the placement space, the battery is fixed to the battery fixing bar 16 by bolts and fixing holes to prevent the battery from falling accidentally. In this way, the large-volume battery rack 100 can be separated and brought into the room first, and then assembled, thereby reducing the difficulty and cost of indoor installation of the battery rack 100.

[0029] In actual implementation, the first frame 11 and the second frame 12 include a plurality of horizontal bars and vertical bars arranged at intervals.

One end of the parallel connecting piece 2 is connected to the first frame 11 via a detachable connection method, such as a snap-fit structure or a locking structure, and the other end of the parallel connecting piece 2 is connected to the second frame 12 of another rack assembly 1 via a detachable connection method, such as a snap-fit structure or a locking structure. In this way, multiple rack assemblies 1 can be sequentially connected adjacent to each other along the width direction of the rack assembly 1, that is, multiple rack assemblies 1 are connected side by side.

[0032] In actual implementation, the parallel connecting piece 2 is connected to the upper surface of the first frame 11 and the second frame 12 so that the adjacent frame components 1 are closely abutted, and the multiple sets of frame components 1 are installed more compactly.
