[0034] The energy storage container mainly includes two parts of the electrical warehouse and the battery warehouse, and there are different accessories in these two parts, such as container type machine room, battery pack, battery management system, energy storage converter and thermal management system. The electrical warehouse mainly places the power distribution cabinet and inverter, which is to better control the circuit, and the battery warehouse mainly places the battery pack. Whether it is user side or power side, grid side, safety is always the first demand of energy storage.
[0035] The fire-fighting function of the fire-fighting system of the energy storage box in the prior art is relatively single. It cannot cope with complex fire in the energy storage box. Moreover, the fire-fighting function of the fire-fighting system of the existing energy storage box is unreasonable; for example, when high temperature or flammable gas appears in the interior of the energy storage device, a single fire-fighting scheme (such as water injection or spraying) is directly implemented, resulting in that the processing method of the fire-fighting device of the energy storage system in the prior art is unreasonable.
[0036] Based on the above problems, the fire detection and alarm unit in the present application can control at least one of the exhaust unit, the fire extinguishing unit and the water injection unit to be in an operating state according to the monitoring results of different sensors, so as to take reasonable fire-fighting measures for the energy storage system. The problem of single fire-fighting measure in the existing energy storage system is solved. The energy storage device can also be extinguished and cooled under the premise of ensuring that the fire-fighting system causes the least damage to the energy storage device, thereby avoiding damage and personnel injury caused by fire.
[0037] Figure 1 Fig. 1 shows the overall structure of the fire-fighting device of the energy storage system in the embodiment of the present disclosure. Figure 2 Fig. 2 shows another view of the overall structure of the fire-fighting device of the energy storage system in the embodiment of the present disclosure. Figure 3 Fig. 3 shows still another view of the overall structure of the fire-fighting device of the energy storage system in the embodiment of the present disclosure. Figure 4 Fig. 4 shows the circuit structure of the fire-fighting device of the energy storage system in the embodiment of the present disclosure. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In the example, the fire-fighting device of the energy storage system is arranged in the battery compartment 101 and the electrical compartment 102 of the energy storage box 100. The fire-fighting device of the energy storage system includes a plurality of battery boxes 10, a fire detection and alarm unit 20, an exhaust unit 30, a fire extinguishing unit 40 and a water injection unit 50.
[0038] Exemplarily, a plurality of battery boxes 10 are arranged in the battery compartment 101 in multiple columns and spaced apart in the upward and downward directions. The battery core is arranged in the battery box 10 to improve the heat dissipation effect between the plurality of battery cores. The plurality of battery cores in the energy storage system can also be in independent individuals under the enclosure of the battery box 10, thereby reducing the influence between the plurality of battery cores.
[0039] The fire detection and alarm unit 20 is arranged in the electrical compartment 102. The exhaust unit 30 includes a smoke sensor 31 and an exhaust assembly 32 which are in communication with the fire detection and alarm unit 20; the smoke sensor 31 is arranged in the battery compartment 101, and the exhaust assembly 32 is arranged on the side wall of the energy storage box 100 and is in communication with the battery compartment 101. The fire extinguishing unit 40 includes a composite sensor 41 and a fire extinguishing assembly 42 which are in communication with the fire detection and alarm unit 20; the composite sensor 41 is arranged in the battery box 10, and the air outlet of the fire extinguishing assembly 42 is in communication with the battery box 10. The water injection unit 50 includes a first temperature sensor 51 and a water injection element 52 which are in communication with the fire detection and alarm unit 20; the first temperature sensor 51 is arranged in the battery compartment 101, and the water outlet 5211 of the water injection element 52 is in communication with the battery compartment 101.
[0040] The benefits of the above arrangement are that the fire detection and alarm unit 20 in the present application can control at least one of the exhaust unit 30, the fire extinguishing unit 40 and the water injection unit 50 to be in operation according to the monitoring results of different sensors, so as to take reasonable fire-fighting measures for the energy storage system. The problem of single fire-fighting measure in the existing energy storage system is solved. The energy storage equipment can be extinguished and cooled under the premise of minimizing the damage to the energy storage equipment caused by the fire-fighting system, so as to avoid damage and personnel injury caused by fire.
[0041] In Figure 4 In examples, the fire detection and alarm unit 20 includes an exhaust controller 21, a fire extinguishing controller 22 and a water injection controller 23; the exhaust controller 21 is in communication with the smoke sensor 31 and the exhaust assembly 32; the fire extinguishing controller 22 is in communication with the composite sensor 41 and the fire extinguishing assembly 42; and the water injection controller 23 is in communication with the first temperature sensor 51 and the water injection element 52. Exemplarily, the composite sensor 41 includes a second temperature sensor 411 and a flammable gas sensor 412. It can be understood that the density of hot air is smaller than that of cold air, and therefore, the smoke sensor 31 and the first temperature sensor 51 are preferably arranged on the top wall of the battery compartment 101.
[0042] The skilled in the art can understand that the exhaust controller 21 drives the exhaust assembly 32 to operate after one of the smoke sensor 31 or the first temperature sensor 51 sends an alarm signal. The fire extinguishing controller 22 drives the fire extinguishing assembly 42 to operate based on the monitoring result of the composite sensor 41; for example, the fire extinguishing controller 22 drives the fire extinguishing assembly 42 to operate after at least one of the second temperature sensor 411 and the combustible gas sensor 412 sends an alarm signal. The water injection controller 23 drives the water injection 52 to be in the on state based on the first temperature sensor 51 reaching a specified condition.
[0043] In another embodiment, the exhaust controller 21 is communicatively connected to the fire extinguishing controller 22. At least one of the exhaust assembly 32, the fire extinguishing assembly 42 and the water injection 52 is in the operating state. For example, the fire extinguishing controller 22 drives the fire extinguishing assembly 42 to operate after at least one of the second temperature sensor 411 and the combustible gas sensor 412 sends an alarm signal, and sends a linkage signal to the exhaust controller 21, so that the exhaust controller 21 controls the exhaust assembly 32 to be in the operating state; to improve the fire-fighting effect on the energy storage device.
[0044] In Figure 1 In an example, the exhaust assembly 32 includes an air outlet 321 and an air inlet 322; the air outlet 321 and the air inlet 322 are respectively arranged on the side wall of the energy storage box 100 and communicate with the battery compartment 101. For example, the air outlet 321 is implemented as an explosion-proof axial flow fan, and the air inlet 322 is implemented as an electric louver. The skilled in the art can understand that when the exhaust unit 30 is in the operating state, the external air enters the battery compartment 101 through the air inlet 322, and the air outlet 321 sucks the smoke, combustible gas in the battery compartment 101 and the gas entering the battery compartment 101 from the outside to the outside, thereby reducing the concentration of combustible gas in the battery compartment 101 and improving the safety factor of the energy storage device. The gas flowing can also reduce the temperature of the battery cell 10. It can be understood that the advantage of arranging the air inlet 322 is to avoid the situation that the air outlet 321 implemented as an explosion-proof axial flow fan has a shortened bearing life in a vacuum environment.
[0045] Preferably, the exhaust assembly 32 and the air inlet 322 are arranged on two side walls parallel to the energy storage box 100. The advantage of such arrangement is that the arrangement of the exhaust assembly 32 and the air inlet 322 can accelerate the speed of gas flow in the battery compartment 101, thereby accelerating the speed of reducing the concentration of combustible gas in the battery compartment 101, and further improving the safety factor of the energy storage device.
[0046] In Figure 2 In an example, the fire extinguishing assembly 42 comprises a fire extinguishing main pipe 421 and a plurality of fire extinguishing branch pipes 422; one end of the plurality of fire extinguishing branch pipes 422 is communicated with the fire extinguishing main pipe 421, and the other end forms the gas outlet and is respectively communicated with the plurality of battery boxes 10. Further exemplarily, the fire extinguishing assembly 42 further comprises a plurality of partition valves (not shown in the figure). Each of the fire extinguishing branch pipes 422 is provided with a partition valve. The fire extinguishing controller 22 is respectively connected in communication with the plurality of partition valves. The advantage of the above setting is that the fire extinguishing controller 22 can accurately spray the fire extinguishing agent into the battery box 10 where the composite sensor 41 sends an alarm signal through the fire extinguishing main pipe 421 and the fire extinguishing branch pipe 422 by controlling the specified partition valve to be turned on for fire extinguishing and cooling. While the other battery boxes 10 are not affected. Exemplarily, the fire extinguishing agent is implemented as perfluorohexanone.
[0047] In Figure 2 And Figure 3 In an example, the water injection member comprises a water injection pipe 521 and an electrically operated opening and closing valve (not shown in the figure) provided on the water injection pipe 521; one end of the water injection pipe 521 is communicated with the battery compartment 101 to form a water outlet 5211; and the electrically operated opening and closing valve is connected in communication with the water injection controller 23. Exemplarily, the water outlet 5211 of the water injection pipe 521 is provided above the battery compartment 101. The other end of the water injection pipe 521 is communicated with a water supply member (not shown in the figure). The water supply member is implemented as a water storage tank or a fire hydrant.
[0048] As can be understood by those skilled in the art, when the first temperature sensor 51 sends an alarm signal under specified conditions, the water injection controller 23 controls the opening and closing valve to be turned on, and the water of the water supply member is injected into the battery compartment 101 through the water injection pipe 521, so as to realize water injection cooling for the battery equipment in the battery compartment 101, thereby avoiding explosion of the energy storage equipment due to excessive internal temperature. Exemplarily, the specified conditions are implemented as: the monitoring data of the first temperature sensor 51 is that the temperature exceeds 80°C and lasts for not less than 10 minutes, or the temperature exceeds 130°C and lasts for not less than 3 minutes.
[0049] In another embodiment, the water injection pipe 521 is provided with a parallel electrically operated opening and closing valve and a manually operated opening and closing valve. The advantage of such a setting is that the energy storage equipment can automatically realize water injection and fire extinguishing, and the staff can also manually open the manually operated opening and closing valve to realize water injection and fire extinguishing.
[0050] Again to Figure 1In an example, the fire-fighting device of the energy storage system further comprises an alarm unit 60 communicatively connected to the fire detection and alarm unit 20. The alarm unit 60 is implemented as a sound and light alarm. The advantage of the above arrangement is that when the fire detection and alarm unit 20 controls any one of the exhaust unit 30, the fire extinguishing unit 40 and the water injection unit 50 to operate, the alarm unit 60 is also operated in linkage to prompt the staff to come to handle and prompt the personnel to move away in the form of sound and light.
[0051] In summary, the fire-fighting device of the energy storage system provided in the embodiments of the present disclosure is arranged in the battery compartment and the electrical compartment of the energy storage box. The fire-fighting device comprises: a plurality of battery boxes arranged in the battery compartment; a fire detection and alarm unit arranged in the electrical compartment; an exhaust unit comprising a smoke sensor communicatively connected to the fire detection and alarm unit and an exhaust assembly; the smoke sensor is arranged in the battery compartment, and the exhaust assembly is arranged in the side wall of the energy storage box and is in communication with the battery compartment; a fire extinguishing unit comprising a composite sensor communicatively connected to the fire detection and alarm unit and a fire extinguishing assembly; the composite sensor is arranged in the battery box, and the air outlet of the fire extinguishing assembly is in communication with the battery box; a water injection unit comprising a first temperature sensor communicatively connected to the fire detection and alarm unit and a water injection member; the first temperature sensor is arranged in the battery compartment, and the water outlet of the water injection member is in communication with the battery compartment. The advantage of the above arrangement is that the fire detection and alarm unit can control at least one of the exhaust unit, the fire extinguishing unit and the water injection unit to be in an operating state according to the monitoring results of different sensors, so as to take reasonable fire-fighting measures for the energy storage system. The problem of single fire-fighting measure in the existing energy storage system is solved. The energy storage equipment can also be extinguished and cooled under the premise of ensuring that the fire-fighting system causes the least damage to the energy storage equipment, so as to avoid damage and personnel injury caused by fire.
