This invention relates to the field of energy storage batteries, specifically disclosing a prefabricated energy storage battery compartment, comprising: a single battery compartment including multiple layers of battery cells arranged in a multi-layered manner; wherein each battery cell includes a liquid cooling plate, a conductive element, and at least one battery module; wherein each battery module has a guide pin at its rear end for limiting connection; the conductive element includes an integrally connected conductive part and an insulating part, the conductive part being used for conductive connection with the battery module; the liquid cooling plate has a first mounting hole on its side for detachable connection with the guide pin, and a second mounting hole on its top for fixing the insulating part. This invention allows for convenient disassembly of the battery module without the use of large tools, facilitating maintenance and repair, significantly reducing maintenance costs, while ensuring good performance of the battery module and stable and reliable heat dissipation of the entire battery cell.

The invention discloses a goaf fire preventing and extinguishing method based on wind flow distribution and dry ice phase change. The method comprises the following steps that the wind flow intersection condition of a goaf and a coal face is measured; detecting the influence range when the dry ice is sublimated into CO2 gas in a laboratory; putting dry ice in the goaf; during stoping, after the goaf roof collapses, the goaf roof coal rock falls onto the heat preservation box filled with the dry ice, the heat preservation box is broken, and the dry ice is buried by the goaf roof coal rock and sublimates to form CO2 gas which is diffused all around for fire prevention and extinguishment. According to the method, the heat preservation boxes filled with the dry ice are arranged in the direction parallel to the coal face and are divided into sections according to wind flow intersection in the goaf, and it is guaranteed that CO2 gas formed after sublimation of the dry ice is evenly distributed in the goaf to the maximum extent. The dry ice in the heat preservation box does not generate phase change when being located in a heat dissipation zone, and sublimates after being smashed by goaf roof coal rocks after falling down when being located in an oxidation zone where spontaneous combustion is most likely to happen, and accurate fire prevention and extinguishing are achieved.
