Double-layer battery prefabricated cabin structure with fireproof isolation function

Abstract

The invention belongs to a fireproof isolation device, and particularly relates to a double-layer battery prefabricated cabin structure with a fireproof isolation function, which comprises two batteryprefabricated cabins arranged up and down and independent from each other and a fireproof isolation space, wherein the upper-layer battery prefabricated cabin in the two battery prefabricated cabinsis mounted above the lower-layer battery prefabricated cabin in a suspended manner, so that a fireproof isolation space is formed between the upper-layer battery prefabricated cabin and the lower-layer battery prefabricated cabin; and the fireproof partition plate is mounted in the fireproof isolation space. In conclusion, the double-layer prefabricated cabin can achieve fire prevention and explosion prevention after the energy storage cabins are arranged in a stacked mode.

Description

technical field [0001] The invention belongs to a fireproof isolation device, in particular to a double-layer battery prefabricated cabin structure with a fireproof isolation function. Background technique [0002] In the prior art, in order to solve the problem that the battery energy storage cabin occupies too much area and the land use efficiency is not high, the traditional 40-foot energy storage cabin is split into two 20-foot energy storage cabins, and the two The energy storage compartments are superimposed. [0003] In the lithium battery energy storage compartment, the battery that is used more is the lithium iron phosphate battery. When the BMS management of the battery management system fails or a single battery in the battery module is overcharged, some single batteries will fail to be overcharged, and the battery shell will be deformed. In severe cases, the entire battery module will fail. , when it fails, combustion will occur in the energy storage cabin, and...

AI Technical Summary

Problems solved by technology

[0008] However, there are technical problems and shortcomings in the existing explosion-proof technical solutions: if the inertization solution is adopted, a large amount of gas is required; the anti-explosion design undoubtedly requires an unlimited increase in the thickness of the box and structural design; In the case of explosion design, the structure design of the larger pressure relief surface of the box is required

The above design is difficult to implement in the project, and the design scheme is relatively simple

[0009] Technical problems and shortcomings in adopting the existing fire protection technical scheme: if adopting the fire protection scheme of building structure, it is necessary to build a fixed floor slab, such a difficult design of the floor slab is difficult to implement in the project, and the lower container cannot be hoisted directly, and the concrete structure design The load-bearing design should reach 2T / m 2 above
