[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Reference Figures 1-3 This utility model discloses an energy storage cabinet with a fire protection system, including a cabinet body 1,

[0024] Cabinet door 2; the cabinet body 1 is composed of inner panel 100, fireproof layer 200 and outer panel 300; wherein the fireproof layer 200 is made of rock wool, which has good fire resistance and effectively improves the overall fire resistance of the cabinet body. In the event of a fire, it minimizes the impact of the fire on the cabinet structure and avoids the fire from affecting the surrounding environment.

[0025] Reference Figure 2 , Figure 4 , Figure 6 , Figure 7 The cabinet 1 is internally divided into an electrical area 101 and a battery area 102. A dry powder storage tank 4 is bolted to the top of the cabinet 1. The dry powder storage tank 4 is equipped with a fire pipe 5. The fire pipe 5 passes through the top of the cabinet 1 and enters the electrical area 101. The fire pipe 5 is connected to a four-way pipe 6. Fire sprinklers A and B are respectively installed on both sides of the four-way pipe 6. Fire sprinklers A are parallel to the fire pipe 5, and fire sprinklers B are horizontal to the fire pipe 5. Fire sprinklers A are parallel to the fire pipe. A fire sprinkler C is also provided at the rear of the four-way pipe 6. The fire sprinkler C is located at the top of the battery area 102. Parallel-mounted fire sprinklers A are primarily used for vertical downward spraying, effectively covering the space around the electrical equipment and suppressing the vertical spread of fire. Horizontally mounted fire sprinklers B are mainly used to spray various horizontal positions within the battery area, covering the gaps between battery packs and the surrounding area. Fire sprinkler C works in conjunction with the air conditioner 7 and air supply duct 8 in the electrical area 101. The air supply duct 8 is fixed to the top of the cabinet 1 by supporting sheet metal 10. The air supply duct 8 directs airflow through the air guide plate 50 in the battery area 102, causing the airflow to flow downwards on both sides of the top of the battery area 102, thus fully covering the interior of the energy storage cabinet with dry powder extinguishing agent. These three configurations function in different directions, compensating for their respective coverage blind spots. Furthermore, after the fire suppression system sprays, extinguishing residue remains on the surface of the battery components. Restarting the air conditioner 7 allows the airflow to simultaneously purge both sides of the battery area 102, dispersing the residue.

[0026] Reference Figure 6 The electrical zone 101 is equipped with a temperature sensor 20 and a smoke detector 30, which can monitor the ambient temperature in real time and prevent fires, thereby improving safety and reducing the potential risks and losses caused by fires.

[0027] Reference Figure 2 , Figure 5 PC guide rail 3 is set on the surface of the base plate 90. PC guide rail 3 has high insulation resistance and dielectric strength, which can effectively isolate electrical signals and prevent leakage and short circuit. At the same time, it is cheaper than metal guide rail, reducing manufacturing costs.

[0028] Reference Figure 1 , Figure 2 , Figure 6 The electrical area 101 is provided with a cable tray 201 on the side panel of the corresponding cabinet 1, which can not only organize the wiring and facilitate inspection and maintenance, but also improve safety and heat dissipation.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the design concept of the present utility model shall be included within the protection scope of the present utility model.
