[0002] With the rapid development of energy storage technology, the demand for ever-increasing battery cell capacity is increasing. For example, commonly used lithium iron phosphate battery storage systems, while popular for their high energy density, also carry the potential risk of thermal runaway. Once a fire occurs, these systems often spread rapidly and are difficult to effectively control.

[0003] Common fire extinguishing cooling devices are unable to make accurate judgments on the fire situation in a timely manner, making it difficult to accurately achieve rapid response and efficient fire extinguishing, causing irreversible damage to the structure and function of the energy storage system.

[0028] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0029] According to some embodiments of the present application, referring to Figure 1 As shown, Figure 1 This is a schematic diagram of the structure of a fire sprinkler device according to an embodiment of the present application. The fire sprinkler device according to an embodiment of the present application is used to spray the battery cluster 1 in the energy storage compartment. The fire sprinkler device includes: a coolant storage tank 2, a pipe 3, a temperature sensor, a base 4, a telescopic assembly 5, and a spray assembly 6. The coolant storage tank 2 is used to store coolant. The pipe 3 is connected to the coolant storage tank 2 and is located above the batteries of the battery cluster 1. The pipe 3 is used to transmit coolant. The temperature sensor is provided in the energy storage compartment and is used to detect the temperature of the battery cluster 1. The base 4 is mounted on the pipe 3 and is electrically connected to the temperature sensor and can collect temperature information detected by the temperature sensor. The telescopic assembly 5 is connected to the base 4 and can be controlled to extend and retract by the base 4. The spray assembly 6 is connected to the telescopic assembly 5 and connected to the pipe 3. The spray assembly 6 can be controlled to spray coolant by the base 4.

[0030] Specifically, the pipeline 3 is a high-temperature resistant water pipe, and the coolant is mainly water.

[0031] Pipe 3 is used to transport coolant, and spray assembly 6 is connected to telescopic assembly 5 and communicates with pipe 3. A temperature sensor is preferably provided on battery cluster 1. In the early stages of a fire, the temperature sensor can accurately identify battery clusters with abnormal temperatures and make timely and accurate judgments on the fire situation. Base 4 is electrically connected to the temperature sensor and can collect temperature information detected by the temperature sensor. Base 4 can also control the telescopic assembly 5 to extend and retract, quickly positioning it to the hottest area in battery cluster 1. Simultaneously, base 4 can control spray assembly 6 to spray coolant, thereby achieving accurate and rapid response and efficient fire extinguishing, quickly controlling the high temperature of the fire scene.

[0032] In other embodiments, a control device may be provided, which is electrically connected to the base 4 and the temperature sensor. After receiving the temperature information detected by the temperature sensor, the control device transmits a signal to the base 4 to control the telescopic component 5 and the injection component 6.

[0033] According to some embodiments of the present application, reference Figure 2As shown, the telescopic assembly 5 includes a fixed rod 51 and a telescopic rod 52. The fixed rod 51 is fixedly mounted on the base 4. One end of the telescopic rod 52 is telescopically mounted within the fixed rod 51 and the other end is connected to the spray assembly 6. The telescopic rod 52 includes a first telescopic link 521 and a second telescopic link 522. One end of the first telescopic link 521 is mounted within the fixed rod 51 and the other end is slidably connected to one end of the second telescopic link 522. The other end of the second telescopic link 522 is connected to the spray assembly 6.

[0034] The telescopic assembly 5 is composed of a fixed rod 51 and a telescopic rod 52. One end of the telescopic rod 52 is telescopically mounted within the fixed rod 51. This allows the extension length of the telescopic rod 52 to be adjusted, accurately delivering the spray assembly 6 to a specified height and achieving precise fire extinguishing. Preferably, the telescopic rod 52 is divided into a first telescopic link 521 and a second telescopic link 522. One end of the first telescopic link 521 is mounted within the fixed rod 51, and the other end is slidably connected to one end of the second telescopic link 522. The other end of the second telescopic link 522 is connected to the spray assembly 6. Separating the telescopic rod 52 into the first telescopic link 521 and the second telescopic link 522 can increase the overall length of the telescopic rod 52. In this case, the lengths of the fixed rod 51, the first telescopic link 521, and the second telescopic link 522 can be appropriately reduced to prevent damage caused by excessive rod length.

[0035] According to some embodiments of the present application, reference Figure 1 The spray assembly 6 includes a rotary joint 61 and a spray head 62 . The rotary joint 61 is rotationally connected to the telescopic assembly 5 . The spray head 62 is fixed on the rotary joint 61 and connected to the pipeline 3 .

[0036] Specifically, “the rotary joint 61 is rotationally connected to the telescopic assembly 5 ” means that the rotary joint 61 can rotate 360° in the horizontal plane.

[0037] The base 4 also controls the rotation angle of the rotary joint 61 in the spray assembly 6. In actual operation, if a single battery cluster 1 catches fire due to excessive heat, adjacent battery clusters 1 could be affected if timely intervention is not taken. To avoid unnecessary impact on battery clusters 1 at normal temperatures, the base 4 issues a water spray command, causing the rotary joint 61 to rotate and the spray head 62 to immediately start spraying water, rapidly extinguishing the fire and reducing the temperature, preventing the fire from spreading.

[0038] Of course, in other embodiments, the spray assembly 6 includes a fixed spray head connected to the pipeline 3, and the fixed spray head is provided with a plurality of nozzles, and the plurality of nozzles are evenly distributed along the circumference of the fixed spray head.

[0039] Specifically, the fixed sprinkler is a cylindrical structure with multiple nozzles arranged around its circumference. When the base 4 receives a temperature anomaly signal from the temperature sensor, it controls the telescopic rod 52 to a specified height, and the fixed sprinkler selectively activates one or more nozzles based on the command from the base 4. For example, if a fire occurs in one battery cluster 1, the nozzle on the side with the temperature anomaly activates to spray and extinguish the fire, while the remaining nozzles remain inactive. If a fire occurs in both battery clusters 1, all nozzles activate simultaneously. Because the fixed sprinkler and telescopic assembly 5 are fixedly connected, preventing relative rotation, the service life of the fixed sprinkler is increased.

[0040] In some instances, reference Figure 2 and Figure 3 . Figure 2 This is a front view of the energy storage system according to an embodiment of the present application. Figure 3 This is a top view of the energy storage system according to an embodiment of the present application. Multiple bases 4 are provided, spaced apart on the pipes 3. Multiple telescopic assemblies 5 and injection assemblies 6 are provided, corresponding one to each base 4. Multiple pipes 3 are provided, converging and connecting to the coolant storage tank 2.

[0041] Multiple pipes 3 converge and connect to the coolant storage tank 2. Multiple bases 4 are spaced apart on the pipes 3 to form a comprehensive sprinkler fire protection network. Multiple bases 4 can operate independently, effectively saving energy.

[0042] refer to Figures 1 to 3 As shown, the energy storage system of an embodiment of the present application includes an energy storage compartment, a battery cluster 1 located within the compartment, and the aforementioned fire sprinkler system. A pipe 3 is located above the battery clusters 1. A spray assembly 6 of the fire sprinkler system is located between two adjacent battery clusters 1. The battery clusters 1 are arranged in multiple rows, with a pipe 3 located above each row.

[0043] Pipes 3 are located above the battery clusters 1, and multiple pipes 3 converge to connect to the coolant storage tank 2. The battery clusters 1 are typically arranged in multiple rows, with a pipe 3 located above each row. A fire sprinkler assembly 6 is located between two adjacent battery clusters 1, forming a comprehensive sprinkler fire protection network. Once a temperature sensor detects a fire, the corresponding base 4 receives a temperature anomaly signal from the temperature sensor. The base 4 then controls the telescopic assembly 5 to reach the designated position, ensuring that the fire extinguishing and cooling processes are initiated as quickly as possible, effectively preventing the spread of the fire.

[0044] The following details the operating principle of this energy storage system: Pipes 3 are located above the battery clusters 1, and multiple pipes 3 converge to connect to the coolant storage tank 2. Based on the layout of the battery clusters 1, a pipe 3 is installed above each row of battery clusters 1. A fire sprinkler assembly 6 is located between adjacent battery clusters 1, forming a comprehensive sprinkler fire protection network. A temperature sensor is preferably located on the battery cluster 1 to provide timely warning of high temperatures. Power is supplied to the fire sprinkler system via wires 7. The base 4 within the fire sprinkler system is electrically connected to the temperature sensor and collects temperature information detected by the temperature sensor. Furthermore, the base 4 controls the telescopic assembly 5 to extend and retract, quickly positioning it to the hottest area within the battery cluster 1, ensuring comprehensive, seamless protection for the battery cluster 1. Simultaneously, the base 4 controls the spray assembly 6 to spray coolant. Furthermore, the base 4 also controls the rotation angle of the rotary joint 61 within the spray assembly 6. To avoid unnecessary impact on the battery cluster 1 at normal temperature, the base 4 issues a water spray command, the rotary joint 61 rotates, and the nozzle 62 immediately starts spraying water, quickly extinguishing the fire and reducing the temperature to prevent the fire from spreading. In addition, the spray assembly 6 can also be a fixed nozzle connected to the pipe 3. The fixed nozzle is provided with multiple nozzles, and the multiple nozzles are evenly distributed along the circumference of the fixed nozzle. When a fire occurs in the battery cluster 1 on one side, the nozzle on the side with the abnormal temperature is turned on to spray and cool down the fire, and the other nozzles are not operated. When a fire occurs in the battery clusters 1 on both sides, all nozzles spray simultaneously. Since the fixed nozzle and the telescopic assembly 5 are fixedly connected and do not rotate relative to each other, the service life of the fixed nozzle can be increased.
