Container for electrochemical energy storage and fire-fighting auxiliary device thereof

The utility model relates to the technical field of containers for electrochemical energy storage, and discloses a container for electrochemical energy storage and a fire-fighting auxiliary device thereof, and the fire-fighting auxiliary device comprises a fire-fighting opening formed in the bottom of the container; and the guide rail is arranged in the container in the vertical direction, and the guide rail is located at the edge of the fire-fighting opening. When the battery cluster breaks down, the locking assembly breaks away from limitation on the battery cluster frame, so that the battery cluster slides out of the fire-fighting opening along the guide rail along with the battery cluster frame, the battery cluster is isolated from other energy storage devices in the container, and the battery cluster can be effectively cooled and extinguished through external fire-fighting equipment; and the fault battery cluster is moved out of the container for cooling and fire extinguishing, so that rapid diffusion of
