Description

Technical Field

[0001] This utility model relates to the field of battery energy storage cabinet technology, specifically a battery energy storage cabinet with a fire extinguishing and early warning mechanism. Background Technology

[0002] A battery energy storage cabinet is a device used to store electrical energy, primarily through battery packs. It plays multiple roles in the power system, including peak shaving and valley filling, improving power quality, and providing backup power. However, during use, battery energy storage cabinets may experience spontaneous combustion due to a series of abnormal conditions such as internal short circuits, overcharging and over-discharging, external high temperatures, battery aging, and damage. This necessitates considering fire warning functionality when designing the battery energy storage cabinet. However, existing fire warning battery energy storage cabinets only consider protection against internal spontaneous combustion and do not address protection against external fire intrusion. This device aims to provide a battery energy storage cabinet with a fire warning mechanism, offering a degree of protection and minimizing damage in the event of an internal or external fire.

The second ceramic fiber plate is set on the side of the cabinet door facing inward, so that when the cabinet door is closed, the second ceramic fiber plate and the first ceramic fiber plate can close accordingly to enclose and protect the battery pack. When the internal battery pack spontaneously combusts, it can prevent the further spread of the flames and prevent damage to other parts of the device. The first dry ice nozzle is used to extinguish the fire in the internal space surrounded by the ceramic fiber plate. The internal space surrounded by the ceramic fiber plate provides an efficient fire extinguishing space, making the fire extinguishing efficiency of dry ice fast and effective. When a fire occurs in the device and invades the device, the ceramic fiber plate space encloses and protects the battery pack, and the second dry ice nozzle sprays dry ice into the device, preventing the internal temperature of the device from rising significantly, thereby effectively protecting the battery pack.

[0016] 2. In this utility model, by setting the fire extinguishing component, when an external fire approaches the device, it can perform preliminary fire extinguishing spray on the periphery of the device to slow down or prevent the flames from approaching. The fire extinguishing component can perform ring spray, which greatly improves the automatic use efficiency of the fire extinguisher and can effectively extinguish and protect the surrounding area of ​​the device. When not in use, the fire extinguisher can also be stored away using the component without affecting normal use.

[0017] 3. In this utility model, by setting up a raised base, the protection of the device is further improved when an external fire approaches. The raised base is equipped with three nozzles facing the ground, which can draw water from the water tank inside the raised base and spray it onto the ground, covering the area around the device with water, slowing down the approach of the fire. At the same time, with the raised base, the device will not be affected by the water and will not come into contact with the flames at the first moment. Attached Figure Description
