Abstract

This application discloses a battery cabinet. A drain assembly is disposed at the bottom of a cabinet body of the battery cabinet. The drain assembly includes a drain valve. A valve spool and a magnetic object are disposed in the drain valve. The valve spool is movably disposed in the drain valve and has a first state of sealing the drain valve or a second state of opening the drain valve. The magnetic object generates a magnetic force to keep the valve spool in the first state, and the valve spool stays in the second state when a downward force applied to the valve spool is greater than a preset value. Therefore, draining is started when the water accumulated on the valve spool reaches a specified weight, and a new valve spool is automatically closed after the water is drained.
