Emergency fire-fighting water tank for battery swap station

Abstract

The invention discloses an emergency fire-fighting water tank for a battery swap station, and belongs to the technical field of energy storage systems. The water tank comprise a box body, an opening is formed in the upper portion of the box body, a reinforcing frame is arranged on the outer surface of the box body, and a thickened lining plate is arranged on a bottom plate in the box body; a water outlet is formed in the upper portion of the box body and connected with a water outlet pipeline, and a water suction pump is arranged on the water outlet pipeline; and a water inlet is formed in the lower portion of the box body and connected with a water inlet pipeline, and a water inlet pump is arranged on the water inlet pipeline. When a battery box is on fire, the battery box is put into the emergency fire-fighting water tank, so that the effects of quickly cooling and extinguishing fire are achieved. The thickened lining plate at the bottom of the box body can prevent the heavy battery box from smashing the bottom plate of the water tank. The reinforcing frame can reinforce the box body, and plays a role in protecting huge pressure generated when the battery box is put into the water tank and explosion impact force of the battery box. Meanwhile, cold water is continuously pumped into the water inlet, hot water is continuously pumped out of the water outlet, efficient heat exchange between the emergency fire-fighting water tank and the battery box is guaranteed, and the purpose of rapidly cooling the battery box is achieved.

Description

technical field [0001] The invention belongs to the technical field of energy storage systems, and in particular relates to an emergency fire-fighting water tank for a power station. Background technique [0002] Electric vehicles obtain power by supplementing electric energy, mainly including charging and battery replacement. Compared with charging, battery swapping has the advantages of short energy supply time and fast resumption of operation. It needs to rely on the swapping station to complete the battery swapping action. When the battery of the electric vehicle is low, it stops at the battery exchange station, and the battery exchange device in the battery exchange station removes the battery box with insufficient power from the electric vehicle, puts it on the charging base in the battery exchange station for charging, and then selects a fully charged battery box Assembled on electric vehicles.
