The interior of the energy storage cabinet is generally equipped with a battery pack, an inverter, a control system and a cooling system. In the prior art, most of the battery compartments used to store battery packs are completely closed. There are only water immersion sensors in the battery compartment without drainage structures. When the cooling pipes in the battery compartment are repaired, water will inevitably overflow. When the overflowed water reaches a certain amount, it will trigger the water immersion sensor alarm. At this time, manual cleaning is used for drainage. This method has the following shortcomings: 1. The efficiency of manual cleaning is low, and there is a risk of electrical appliances in the battery compartment being flooded; 2. When a small amount of water overflows, it will not trigger the water immersion sensor alarm, and it will not be cleaned. The accumulated water may penetrate into other compartments and damage the devices in other compartments; 3. The installed water immersion sensor increases the cost of the energy storage cabinet.

[0003] There is no solution to the above problem at present. The Chinese utility model patent with the authorization announcement number CN209921109U discloses "a rainproof drainage mechanism for the battery compartment of an intelligent battery swap station", which proposes a technical solution for the field of intelligent battery swap stations for electric vehicles to achieve drainage of battery swap stations in rainy days or in bad weather conditions to ensure the service life and stability of battery swap stations.
