[0027] Example 1

[0028] This utility model provides a combined battery rack with a fire protection system, please refer to Figure 1 - Figure 4, including a battery rack and a fire protection component, wherein the battery packs are stacked in the battery rack; the fire protection component includes at least two fire protection pipes and a delivery pipe 501, wherein the fire protection pipes are respectively arranged on the sides of the battery rack along the height direction of the battery rack, and the bottoms of the two fire protection pipes are respectively connected to the delivery pipes 501, and a plurality of fire protection nozzles 6 corresponding to the battery packs are arranged on the side of the fire protection pipe facing the battery pack.

[0029] In this embodiment, by integrating firefighting components into the battery rack, firefighting measures can be promptly initiated in the event of an emergency, such as a thermal runaway, in the battery pack. This effectively reduces the risk of fire and ensures the safety of personnel and equipment. Firefighting piping is arranged along the height of the battery rack, and firefighting nozzles 6 are positioned on the side facing the battery pack, corresponding to each battery pack. This enables precise firefighting. Each firefighting nozzle 6 can be directly aimed at its corresponding battery pack, ensuring that the firefighting agent quickly reaches the fire source, improving firefighting efficiency and achieving targeted firefighting control for the energy storage system. Firefighting agent can be sprayed directly and accurately at the fire point, improving firefighting efficiency and reducing firefighting agent waste. The layout and positioning of the firefighting piping, delivery pipe 501, and firefighting nozzles 6 achieves pack-level active protection, precisely delivering firefighting agent to each battery pack, achieving early extinguishing and preventing the re-ignition and spread of lithium battery fires. Furthermore, the firefighting components utilize a modular design for easy installation, inspection, and maintenance. When the firefighting system needs to be replaced or maintained, the firefighting components can be operated independently without affecting the normal operation of the rest of the battery rack.

[0030] Optionally, the battery rack includes supporting columns and column fixing beams, and the supporting columns and the column fixing beams form a rectangular frame.

[0031] For details, please continue to refer to Figure 1 , the battery rack includes a first supporting column 101, a second supporting column 102, a third supporting column 103 and a fourth supporting column 104; the battery rack also includes a first column fixed beam 201, a second column fixed beam 202, a third column fixed beam 203, a fourth column fixed beam 204, a fifth column fixed beam 205, a sixth column fixed beam 206, a seventh column fixed beam 207 and an eighth column fixed beam 208.

[0032] Optionally, it also includes a plurality of battery support racks 4 stacked on the battery rack, and the battery support rack 4 includes a first support beam 401 and a second support beam 402 located at the same height and arranged opposite to each other; the first support beam 401 is arranged on two adjacent support columns, and the second support beam 402 is arranged on the other two adjacent support columns.

[0033] In this embodiment, each group of battery support frames 4 includes a first support beam 401 and a second support beam 402 located at the same height and arranged opposite to each other, one end of the first support beam 401 is arranged on the first support column 101, the other end of the first support beam 401 is arranged on the second support column 102, and the first support beam 401 is located on the same side of the first support column 101 and the second support column 102; one end of the second support beam 402 is arranged on the third support column 103, the other end of the second support beam 402 is arranged on the fourth support column 104, and the second support beam 402 is located on the same side of the third support column 103 and the fourth support column 104.

[0034] Optionally, the first support beam 401 and the second support beam 402 both include a first plate and a second plate arranged vertically, wherein the two ends of the first plate are respectively connected to two adjacent support columns, and the second plates of the first support beam 401 and the second support beam 402 are parallel to each other and jointly provide a support surface for placing the battery pack.

[0035] In this embodiment, the rectangular frame formed by the support columns and the column fixing beams enhances the structural stability. The rectangular frame structure provides a solid support that can bear the weight of the battery pack and maintain the stability of the entire battery rack. The design of the rectangular frame facilitates the expansion of the battery rack. The support columns and fixing beams can be added or reduced as needed to accommodate battery storage needs of different sizes. By stacking the battery support rack 4, more battery packs can be accommodated in a limited space, thereby improving space utilization. The stacked structure makes the maintenance and inspection of the battery pack more convenient, and the operator can easily access the battery packs on each layer.

[0036] Furthermore, the battery support frame 4, positioned at the same height and arranged opposite each other, evenly distributes the weight of the battery pack, reducing pressure on any single support point. A vertical first plate connects two adjacent support posts, increasing the stability of the battery support frame 4 and preventing the battery pack from tilting or falling during placement or transportation. The support surface provided by the two parallel second plates ensures stable placement of the battery pack, reducing the risk of damage caused by unstable placement.

[0037] For details, please refer to Figure 2 The fire sprinkler 6 is a water mist sprinkler. By utilizing the water mist sprinkler and its hydraulic characteristics, the efficiency of fire extinguishing and protective cooling is improved, ensuring that the spray particle size is small and uniform within the effective range, significantly improving the fire extinguishing effect. The fine water mist particles produced by the water mist sprinkler can quickly absorb heat and reduce the flame temperature, thereby achieving rapid fire extinguishing. In addition, water mist fire extinguishing causes less damage to equipment than other fire extinguishing media (such as dry powder), which is beneficial for protecting battery packs and surrounding equipment. While extinguishing the fire, the water mist sprinkler can also cool the surrounding environment to prevent the fire from rekindling.

[0038] Optionally, the fire sprinkler 6 is higher than the supporting surface in the vertical direction.

[0039] In this embodiment, the battery packs are stacked on the battery support rack 4, with fire sprinklers 6 corresponding to each battery pack on each layer. Each fire sprinkler 6 is vertically higher than the support surface of the battery pack and slightly higher than the battery pack itself. This allows the water mist sprinkler to better contact the fire's hot air flow and evenly distribute water. This also ensures that the sprayed water mist covers both above and below the battery pack, providing comprehensive fire extinguishing protection.

[0040] Optionally, the two fire-fighting pipes are respectively arranged on two adjacent support columns, and are respectively close to the same end of the first support beam 401 and the second support beam 402. The two ends of the delivery pipe 501 are respectively connected to the two fire-fighting pipes, and a delivery port is opened on the main body of the delivery pipe 501.

[0041] Preferably, the fire-fighting pipeline is fixed to the supporting column by a pipe clamp, and the side wall type fire-fighting sprinkler 6 is connected to the fire-fighting pipeline.

[0042] In this embodiment, the two fire protection pipes include a first fire protection pipe and a second fire protection pipe. The first fire protection pipe is fixed to the first support column 101 via a pipe clamp, and the second fire protection pipe is fixed to the fourth support column 104 via a pipe clamp. Using pipe clamps to secure the fire protection pipes to the support columns ensures the stability of the fire protection pipes in the battery rack, reduces potential displacement during operation or vibration, and simplifies the installation process, eliminating the need for complex welding, facilitating quick installation and subsequent maintenance.

[0043] In this embodiment, please continue to refer to Figure 1 - Figure 2 The two fire protection pipes are respectively arranged on the two adjacent support columns and are close to the same side of the battery support frame 4 to ensure that each battery pack is within the effective coverage range of the fire protection pipe.

[0044] Optionally, the fire-fighting pipe is arranged between the upper and lower column fixing beams, and a first groove running through the column fixing beam close to the ground is provided, and the supporting column close to the first groove is provided with a second groove connected to the first groove and running through the horizontal direction.

[0045] In this embodiment, the tail end of the fire protection pipe is connected to the delivery pipe 501 through the first groove and the second groove; the delivery pipe 501 is perpendicular to the first fire protection pipe 502 and the second fire protection pipe 503, and a delivery port is opened on the main body of the delivery pipe 501. The two ends of the delivery pipe 501 are respectively connected to the two fire protection pipes to form a closed fire extinguishing agent delivery system. The fire extinguishing agent is delivered through the delivery port to deliver the fire extinguishing agent to the first fire protection pipe 502 and the second fire protection pipe 503 when a fire occurs. The fire extinguishing agent is finally evenly sprayed out through multiple fire sprinklers 6.

[0046] Furthermore, part or all of the fire protection pipes and delivery pipes 501 can be concealed within the column fixing beams and support columns, making the overall structure more aesthetically pleasing while not affecting the normal operation of the battery rack. By utilizing the space between the column fixing beams and support columns, additional space is reduced, making the overall design of the battery rack more compact. The combined battery rack with a fire protection system provided in this embodiment not only improves safety but also comprehensively considers the system's concealment, ease of installation and maintenance, and overall aesthetics.

[0047] Furthermore, it also includes smoke / temperature detectors, combustible gas sensors, and Pack temperature sensors. The smoke / temperature detectors, combustible gas sensors, and Pack temperature sensors are installed inside the battery rack to monitor the battery pack. By building a multi-layer early warning technology, accurate early warning of electrical fires and lithium-ion battery fires can be achieved.
