Description

Technical Field

[0001] The utility model relates to the technical field of battery cabinets, in particular to a battery energy storage cabinet with an automatic fire-fighting function. Background Art

[0002] Energy storage battery cabinets are equipment used to store and manage energy storage battery packs, and are usually used in renewable energy systems such as solar energy and wind energy. The main functions of energy storage battery cabinets are to protect battery packs, manage the charging and discharging process of battery packs, monitor battery status, etc. Energy storage battery cabinets have multiple safety protection functions, such as overcharge protection, over-discharge protection, short-circuit protection, etc., to ensure that the battery pack operates within a safe range. Energy storage battery cabinets can manage battery packs, including charging and discharging control, battery status monitoring, etc., to ensure the normal operation of battery packs and extend battery life. Energy storage battery cabinets usually have communication interfaces, which can communicate data with monitoring systems, energy management systems, etc. to achieve remote monitoring and control. Energy storage battery cabinets can adjust charging and discharging according to the load conditions of the power grid, achieve efficient use of energy, reduce dependence on traditional energy, and achieve the purpose of energy conservation and environmental protection. Some energy storage battery cabinets adopt modular design, which can be expanded or reduced as needed to improve the flexibility and maintainability of the system. Considering that the battery pack will generate heat during the charging and discharging process, the energy storage battery cabinet usually has a good heat dissipation design to ensure that the battery pack operates within an appropriate temperature range. However, when a battery failure occurs and causes a fire, it is necessary to promptly extinguish the battery inside the cabinet and sound an alarm to remind the staff to put out the fire in the cabinet. Usually, a fire extinguisher or a storage tank for fire extinguishing storage is placed on the cabinet to place dry powder in the storage tank.

[0003] After searching, the Chinese patent publication number CN218187606U discloses a storage battery cabinet with fire-fighting function, including a cabinet body, two groups of symmetrically distributed powder spraying pipes are fixedly connected in the cabinet body, and the number of each group is not less than two, and a number of spray heads are arranged on the powder spraying pipes, a first connecting piece is arranged between the two groups of the powder spraying pipes, and a second connecting piece is arranged between each group of the powder spraying pipes, and a powder spraying mechanism connected to the second connecting piece is arranged on the top of the cabinet; the powder spraying mechanism includes multiple powder storage cylinders.

[0004] In the above scheme, the outer cylinder on the cabinet is used to expand the liquid inside when heated to achieve the alarm effect. However, batteries in different positions generate different temperatures when they cause fire. For example, when a fire occurs in the batteries on the bottom or upper layers, there will be a delay in transferring the heat temperature to the outer cylinder, and the liquid that expands due to heat needs time to heat the liquid, which will prolong the alarm time of the alarm. Utility Model Content
