Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] The energy storage system 400 generally consists of a battery compartment 401, a liquid-cooled unit compartment 402, a power distribution cabinet 403, a combiner cabinet 404, and a switch box. Battery modules 4011 are placed inside the battery compartment 401. Figure 2 As shown, the battery compartment 401 is separated from other compartments by a partition 405 filled with rock wool, forming an independent compartment.

[0037] With the large-scale application of electrochemical energy storage systems, energy storage safety accidents have continued to occur, raising increasing awareness. Safety has become the primary factor in evaluating energy storage systems, while fire protection systems, as the last line of defense against fire, have become an essential configuration for energy storage systems.

[0038] The fire protection system of an energy storage system 400 generally includes a water fire protection system and a gas fire protection system. The water fire protection system and the gas fire protection system each have independent fire protection pipelines, which makes the fire protection system occupy a large space in the energy storage system and has a high cost.

[0039] Therefore, such as Figure 1 As shown in the figure, this application discloses a fire protection system, including a fire protection network 100, a water fire protection system 200, and a gas fire protection system 300. By connecting the water fire protection system 200 to the main pipeline 101 of the fire protection network 100 through a water fire protection pipeline 201, and simultaneously connecting the gas fire protection system 300 to the main pipeline 101 of the fire protection network 100 through a gas fire protection pipeline 301, the water fire protection system 200 and the gas fire protection system 300 can share the fire protection network 100, thereby reducing the space occupied by the fire protection system and lowering the cost of the fire protection system.

[0040] The following will combine Figures 1 to 6 The fire protection system disclosed in the embodiments of this application will be explained and described in detail.

[0041] like Figure 1As shown, the fire-fighting pipe network 100 includes a main pipe 101 and branch pipes 102 in communication with the main pipe 101, and the branch pipes 102 are arranged in the battery cabin 401 of the energy storage system 400. Moreover, the water fire-fighting system 200 is in communication with the main pipe 101 through a water fire-fighting pipe 201, and the gas fire-fighting system 300 is in communication with the main pipe 101 through a gas fire-fighting pipe 301, so as to realize the effect that the water fire-fighting system 200 and the gas fire-fighting system 300 share the fire-fighting pipe network 100, and the fire-fighting of the battery module and the fire-fighting of the battery cabin share the fire-fighting pipe network 100, thereby reducing the occupied space of the fire-fighting system, making the integration of the fire-fighting system and the energy storage system 400 more compact and efficient, and reducing the cost of the fire-fighting system.

[0042] When a fire occurs in the battery cabin 401 of the energy storage system 400, the gas fire-fighting system 300 can be turned on, so that the fire extinguishing agent enters the battery cabin 401 through the gas fire-fighting pipe 301, the main pipe 101 of the fire-fighting pipe network 100 and the branch pipes 102 of the fire-fighting pipe network 100 in sequence to perform the fire extinguishing action. If the gas fire extinguishing is not completed, the water fire-fighting system 200 can be turned on, so that the external water source enters the battery cabin 401 through the water fire-fighting pipe 201, the main pipe 101 of the fire-fighting pipe network 100 and the branch pipes 102 of the fire-fighting pipe network 100 in sequence to perform the fire extinguishing action.

[0043] Further, as shown in Figure 1 and Figure 3 , the water fire-fighting pipe 201 includes an external water pipe 2011 connected with the main pipe 101 and a first one-way valve 2012 arranged on the external water pipe 2011. The external water pipe 2011 is connected with a water supply device, and the first one-way valve 2012 can prevent water from flowing back to the water supply device, thereby improving the fire extinguishing efficiency. Preferably, the main pipe 101 and the external water pipe 2011 are made of seamless steel pipes. Moreover, an end of the external water pipe 2011 is provided with a water interface 2013 for connecting with the water supply device. The water interface 2013 can be located inside the energy storage system 400 and connected with the water supply device in the energy storage system 400. Of course, the water interface 2013 can also be located on the outer wall of the cabinet of the energy storage system 400, so as to be convenient for connecting with the external water source or the water supply device, and to avoid the risk that the battery module 4011 in the battery cabin 401 is contaminated by water due to leakage of the water supply device. In the embodiment, the main pipe 101 is located at the top of the battery cabin 401 of the energy storage system 400, and the water interface 2013 is arranged on the outer wall of the bottom of the cabinet of the energy storage system 400, which is helpful to optimize the space layout of the energy storage system 400, so that the integration of the water fire-fighting system 200 and the energy storage system 400 is more compact and efficient. Moreover, it is convenient for regular maintenance and detection of the water fire-fighting system 200, thereby ensuring the reliability of the water fire-fighting system 200 in emergency.

[0044] Further, as shown in Figure 1 the water flow can be prevented from flowing downward by gravity, i.e. the water flow can flow upward to the main pipeline 101, at this time the first one-way valve 2012 is in an open state, and when the water flow flows downward, the first one-way valve 2012 is in a closed state, so that the water flow cannot flow downward. Preferably, the first one-way valve 2012 is arranged at the end of the external water pipe 2011 close to the main pipeline 101, so that when the water fire extinguishing system 200 is started, the pressure loss is minimized. It should be noted that the water supply device in the above embodiment can be a water storage tank, and a drive pump is arranged on the output pipeline of the water storage tank to provide power for the water supply of the water storage tank.

[0045] Further, as shown in Figure 1 the gas fire extinguishing pipeline 301 includes an external gas pipe 3011 connected with the main pipeline 101 and a second one-way valve 3014 arranged on the external gas pipe 3011, and the external gas pipe 3011 is connected with a gas supply device 3013 through a connecting hose 3012. The gas supply device 3013 can be a fire extinguishing agent cylinder, and the gas supply device 3013 is located in a cabin above the power distribution cabinet 403. The external gas pipe 3011 can be a rigid pipe same as the main pipeline 101 and is connected vertically with the main pipeline 101, and the relative position error between the gas supply device 3013 and the main pipeline 101 can be compensated through the connecting hose 3012. In this embodiment, the connecting hose 3012 can be, but is not limited to, a fiber-reinforced polyurethane hose, a steel wire-reinforced polyurethane hose, a steel wire-reinforced nylon hose and the like high-pressure hose.

[0046] Further, as shown in Figure 1 the gas flow can be prevented from flowing downward, i.e. the gas flow can flow upward to the main pipeline 101, at this time the second one-way valve 3014 is in an open state, and when the gas flow flows downward, the second one-way valve 3014 is in a closed state, so that the gas flow cannot flow downward. Preferably, the second one-way valve 3014 is arranged at the end of the external gas pipe 3011 close to the main pipeline 101, so that when the gas fire extinguishing system 300 is started, the pressure loss is minimized.

[0047] Further, in order to be able to extinguish the fire point in the energy storage system 400, a first spray hole can be arranged on the main pipeline 101, and a second spray hole can be arranged on the branch pipeline 102, when a fire occurs in the energy storage system 400, the first spray hole and the second spray hole can be used to spray fire extinguishing gas or water to the fire point in the energy storage system 400, so as to achieve the effect of extinguishing the fire.

[0048] Further, in order to ensure the reliability of the fire extinguishing system while reducing the cost of the fire extinguishing system, as shown in Figure 1As shown, in a specific embodiment, the fire-fighting pipe network 100 further comprises a first spray head 1011 arranged on the main pipe 101 and a second spray head 1021 arranged on the branch pipe 102. Specifically, the first spray head pipe 1012 is connected to the main pipe 101, and the first spray head 1011 is arranged on the first spray head pipe 1012, and the first control valve 1013 for controlling the first spray head 1011 is arranged on the first spray head pipe 1012. The second spray head pipe 1022 corresponding to the battery module 4011 of the battery cabin 401 is connected to the branch pipe 102, the second spray head 1021 is arranged on the second spray head pipe 1022, and the second control valve 1023 for controlling the second spray head 1021 is arranged on the second spray head pipe 1022. Preferably, the first spray head 1011 and the second spray head 1021 can adopt high-pressure spray heads to ensure that the sprayed gas or water has sufficient pressure, thereby improving the fire extinguishing efficiency. At the same time, the branch pipe 102 is made of plastic material, and extends from the main pipe 101 at the top of the battery cabin 401 to the inside of the battery cabin 401 along the column of the battery cabin 401, and the second spray head pipe 1022 is connected to the branch pipe 102 and corresponds to the battery module 4011 of the battery cabin 401, so that when the fire point is located at the position of the battery module 4011 in the battery cabin 401, the second control valve 1023 at the position of the battery module 4011 can be controlled to achieve accurate fire extinguishing effect on the fire point. Of course, the first spray head 1011 can also be arranged directly on the main pipe 101 to achieve cabin-level fire extinguishing effect. It should be noted that the first control valve 1013 and the second control valve 1023 in the above embodiment can adopt, but are not limited to, electric explosion valves.

[0049] Further, in order to improve the fire extinguishing efficiency, in the present embodiment, the first spray head pipe 1012 is at least two, and at least two first spray heads 1011 are arranged on each first spray head pipe 1012. Specifically, when the first spray head pipe 1012 is two, and two first spray heads 1011 are arranged on each first spray head pipe 1012, i.e. two first spray heads 1011 are arranged at the top of each battery cabin 401, the end of the first spray head pipe 1012 is connected to the connecting pipe 1014, and the two first spray heads 1011 are respectively located at the two ends of the connecting pipe 1014, and the first control valve 1013 is arranged at the position where the connecting pipe 1014 is connected to the first spray head pipe 1012, so that the two first spray heads 1011 can be controlled simultaneously by the first control valve 1013. Of course, the number of first spray head pipes 1012 can also be three, four or more as the number of battery cabins 401 increases, and the number of first spray heads 1011 on each first spray head pipe 1012 can also be three, four or more according to actual needs, which is not limited herein.

[0050] In a specific embodiment, when a fire is found in a single battery module 4011, the second control valve 1023 of the second spray pipe 1022 corresponding to the battery module 4011 is turned on, and the fire extinguishing agent of the gas fire extinguishing system 300 enters the main pipe 101 through the gas fire extinguishing pipe 301, and is released through the second spray head 1021 on the second spray pipe 1022, thereby completing the fire extinguishing action; when a fire occurs in the battery cabin 401, the first control valve 1013 of the first spray pipe 1012 is turned on, and the fire extinguishing agent of the gas fire extinguishing system 300 enters the main pipe 101 through the gas fire extinguishing pipe 301, and is released through the first spray head 1011 of the first spray pipe 1012, thereby completing the fire extinguishing action; when the gas fire extinguishing release is completed and the fire extinguishing task is not completed, the external water pipe 2011 can be connected, so that the external water source is released through the first spray head 1011 of the first spray pipe 1012 or enters the battery module 4011 through the second spray head 1021 of the second spray pipe 1022 to extinguish the fire.

[0051] As can be seen from the above embodiments, the fire extinguishing system of the present application can realize the sharing of the fire extinguishing pipe network 100 by the water fire extinguishing system 200 and the gas fire extinguishing system 300, and also has the functions of battery module 4011 fire extinguishing and battery cabin 401 fire extinguishing, and has a compact structure and small space occupation. In addition, by arranging the first one-way valve 2012 and the second one-way valve 3014 at the ends of the external water pipe 2011 and the external gas pipe 3011 respectively, when the gas fire extinguishing system 300 is started, the gas will not enter the external water pipe 2011, and similarly, when the water fire extinguishing system 200 is started, the water will not enter the external gas pipe 3011, thereby minimizing the loss of water pressure and gas pressure and improving the fire extinguishing effect.

[0052] Further, as shown in Figure 2 , Figure 5 and Figure 6 , the fire extinguishing pipe network 100 further comprises a fixed assembly 103 for fixing the pipe. The fixed assembly 103 comprises a fixed support 1031 and a clamp 1032, and the clamp 1032 is connected to the fixed support 1031 by a fastener. In this embodiment, the fixed support 1031 is fixed to the top of the cabinet of the energy storage system 400 by a fastener, and the main pipe 101 is fixed to the fixed support 1031 by the clamp 1032, thereby realizing the fixation of the main pipe 101 of the fire extinguishing pipe network 100.
