[0058] Reference Figure 1 The embodiment of the present application provides an energy storage container, including a box body 10, a plurality of battery clusters 20 and a plurality of partition boards 30; the box body 10 is provided with a detection component 40 (such as Figure 6 ); each of the battery clusters 20 is disposed in the box 10, and each of the battery clusters 20 includes a plurality of battery clusters 21; in the battery clusters 20, a partition plate 30 is disposed between two adjacent battery clusters 21; the partition plate 30 is provided with a cavity 31 and a plurality of openings 32 (such as Figure 4 ), the cavity 31 is connected to the space outside the partition plate 30 through the multiple openings 32; the partition plate 30 is provided with a first air intake component 33 (such as Figure 4 ), the first air suction component 33 is connected to the cavity 31, and the first air suction component 33 is used to absorb the gas in the box body 10 through the cavity 31 and the multiple openings 32, and transport the gas to the detection component 40; the detection component 40 is used to detect the gas, obtain the detection result, and display an alarm message when the detection result includes a result indicating that the energy storage container is on fire.

[0059] For example, the energy storage container includes a box body 10, two battery cluster columns 20 and eight partition plates 30. Each battery cluster column 20 is arranged in the box body 10, and each battery cluster column 20 includes five battery clusters 21. In the battery cluster column 20, a partition plate 30 is arranged between two adjacent battery clusters 21.

[0060] It should be noted that the gas in the present application is a pure gas or a gas containing impurities, and the impurities may be smoke or other forms of substances.

[0061] The plurality of battery clusters 21 in the battery cluster column 20 are arranged in a column, and a passage is provided between two adjacent battery cluster columns 20 for the staff to pass through.

[0062] Reference Figure 3The partition plate 30 is fixedly disposed in the box body 10, specifically disposed between two adjacent battery clusters 21; the partition plate 30 is a hollow plate structure, and the partition plate 30 is a fireproof material, such as a metal material; refer to Figure 4 The openings 32 on the partition plate 30 are respectively connected to the cavity 31 of the partition plate 30 and the space outside the partition plate 30 .

[0063] Specifically, in some embodiments, the detection component 40 may be disposed at the top of the box 10; the detection component 40 includes a smoke alarm, a temperature sensor, a humidity sensor, and the like.

[0064] It should be noted that the alarm information may be in the form of sound, light, image, etc. For example, the smoke alarm in the detection component 40 may generate sound and light alarms when it detects that the gas contains smoke generated by fire.

[0065] Reference Figure 2 In some embodiments, the housing 10 is provided with a plurality of ventilation holes 70 , and the ventilation holes 70 are used to allow the space inside the housing 10 to exchange gas with the space outside the housing 10 .

[0066] In the embodiment of the present application, the first air suction component 33 absorbs the gas in the box body 10 through the cavity 31 and the plurality of openings 32 of the partition plate 30, and transports the gas to the detection component 40, and then the gas is detected by the detection component 40 to obtain the detection result, and when the detection result includes a result characterizing a fire in the energy storage container, an alarm message is displayed. In this process, since the first air suction component 33 can shorten the time for the gas to reach the detection component 40, the detection efficiency is improved, the fire is discovered and handled in time, and the risk of scrapping the energy storage container is reduced.

[0067] Optional, see Figure 6 In some embodiments, the energy storage container further comprises a plurality of first storage tanks 50, each of which has an inner cavity containing a first fluid fire extinguishing medium; each of the partition plates 30 has a corresponding first storage tank 50; each of the first storage tanks 50 is provided with a fluid delivery pipe 51; the fluid delivery pipe 51 of the first storage tank 50 is respectively connected with the inner cavity of the first storage tank 50 and the cavity 31 of the partition plate 30 corresponding to the first storage tank 50; the fluid delivery pipe 51 is provided with a first control valve 52, which is used to open when the detection result includes a result indicating that the energy storage container is on fire, so that the first fluid fire extinguishing medium of the first storage tank 50 flows into the cavity 31 of the partition plate 30 corresponding to the first storage tank 50, and flows out through the opening 32 of the partition plate 30 corresponding to the first storage tank 50.

[0068] It should be noted that the first fluid fire extinguishing medium may be water or other fluid fire extinguishing medium, and the first fluid fire extinguishing medium is preferably water.

[0069] Specifically, in some embodiments, the first storage tank 50 is disposed on the top of the storage container, and the first storage tank 50 is disposed between two adjacent first storage tanks 50, and the first storage tank 50 is connected to the cavities 31 of the two adjacent partition plates 30 corresponding to the first storage tank 50 through multiple fluid delivery pipes 51.

[0070] Reference Fig.12 In the case where the detection result includes the result of characterizing the fire of the energy storage container, the first control valve 52 is opened, and the first fluid fire extinguishing medium in the first storage tank 50 flows into the cavity 31 of the partition plate 30, and a medium layer 321 (for example, a water layer) is formed in the cavity 31 of the partition plate 30, that is, the cavity 31 is filled with the first fluid fire extinguishing medium, thereby increasing the flame retardant effect of the partition plate 30 between two adjacent battery clusters 21 and improving the protection effect of other battery clusters 21. At the same time, part of the first fluid fire extinguishing medium can flow out from the openings 32 on the two surfaces of the partition plate 30, forming a fluid curtain 322 (for example, a liquid curtain) on the outside of the two surfaces of the partition plate 30. Water curtain), that is, a first fluid fire extinguishing medium layer is formed on the surface of the partition plate 30, the fluid curtain 322 can dissolve part of the harmful gas, and can also dissolve part of the smoke particles to prevent the harmful gas and smoke from drifting to other battery clusters 21, the fluid curtain 322 is a flowing fluid fire extinguishing medium (such as water), and therefore has a cooling effect, the fluid curtain 322 can reduce the temperature rise effect of a single battery cluster 21 ignited by an explosion or combustion on other battery clusters 21, thereby maximizing the effective protection of other battery clusters 21, so as to reduce the number of battery clusters 21 performing fire extinguishing operations and reduce the asset loss of the battery clusters 21.

[0071] In the embodiment of the present application, the first control valve 52 is opened when the detection results include results indicating that the energy storage container is on fire, so that the first fluid fire extinguishing medium of the first storage tank 50 flows into the cavity 31 of the partition plate 30 corresponding to the first storage tank 50, and flows out through the opening 32 of the partition plate 30 corresponding to the first storage tank 50. A medium layer 321 can be formed in the cavity 31 of the partition plate 30, and a fluid curtain 322 can be formed on the outer sides of the two surfaces of the partition plate 30, which is conducive to preventing the spread of fire.

[0072] Optional, see Fig.10 In some embodiments, the opening 32 is provided with an opening control component 34; the opening control component 34 is arranged in the cavity 31, and the opening control component 34 is used to block part of the holes of the opening 32 of the partition plate 30 when the first fluid fire extinguishing medium flows into the cavity 31 of the partition plate 30.

[0073] In the embodiment of the present application, when the first fluid fire extinguishing medium flows into the cavity 31 of the partition plate 30 through the opening control component 34, part of the holes of the opening 32 of the partition plate 30 are blocked, so that the rate at which the first fluid fire extinguishing medium flows out of the cavity 31 can be reduced, which is conducive to forming a better fluid curtain 322 on the outer wall of the partition plate 30, making the fluid curtain 322 more uniform, and at the same time, it can also extend the existence time of the medium layer 321 in the partition plate 30 and improve the partition effect.

[0074] Optionally, in some embodiments, the opening control component 34 includes an elastic member 342 and a movable sealing plate 341; the lower side of the movable sealing plate 341 is fixedly connected to the elastic member 342; the elastic member 342 is fixedly connected to the lower side of the opening 32; the movable sealing plate 341 is provided with a first through hole 343, and the diameter of the first through hole 343 is smaller than the diameter of the opening 32; wherein, when the cavity 31 of the partition plate 30 is empty, the upper side of the movable sealing plate 341 is separated from the upper side of the opening 32; when the first fluid fire extinguishing medium flows into the cavity 31 of the partition plate 30, the upper side of the movable sealing plate 341 is fitted with the upper side of the opening 32, and all or part of the holes of the first through hole 343 overlap with the holes of the opening 32 to block part of the holes of the opening 32.

[0075] It should be noted that the buoyancy of the movable sealing plate 341 in the first fluid fire extinguishing medium is greater than the gravity of the movable sealing plate 341 .

[0076] Specifically, the elastic member 342 may be made of high temperature resistant rubber material.

[0077] When the energy storage container is not on fire, the movable sealing plate 341 flips away from the air hole under the action of its own weight, and the upper side of the movable sealing plate 341 is separated from the upper side of the opening 32, so that the opening 32 is fully opened to increase the air intake space of the opening 32, which is conducive to the entry of gas through the fully opened opening 32. When the energy storage container is on fire, the first fluid fire extinguishing medium (such as water) is injected into the cavity 31 through the fluid delivery pipe 51. After the first fluid fire extinguishing medium overflows the movable sealing plate 341, the movable sealing plate 341 flips toward the opening 32 under the action of buoyancy to block the opening 32. The first fluid fire extinguishing medium flows outward through the first through hole 343 to form a uniform water curtain, thereby ensuring that the smoke can be effectively identified while also ensuring effective control of the formation of the fluid curtain 322.

[0078] In the embodiment of the present application, when the cavity 31 of the partition plate 30 is empty, the upper side of the movable sealing plate 341 is separated from the upper side of the opening 32 so that gas can enter through the completely opened opening 32. Since the diameter of the opening 32 is larger than the diameter of the first through hole 343, it is beneficial to ensure the gas suction speed; when the first fluid fire extinguishing medium flows into the cavity 31 of the partition plate 30, the upper side of the movable sealing plate 341 is fitted with the upper side of the opening 32, and all or part of the holes of the first through hole 343 overlap with the holes of the opening 32 to block part of the holes of the opening 32. This can reduce the rate at which the first fluid fire extinguishing medium flows out of the cavity 31, which is beneficial to form a better fluid curtain 322 on the outer wall of the partition plate 30, making the fluid curtain 322 more uniform, and also prolonging the existence time of the medium layer 321 in the partition plate 30, thereby improving the partition effect.

[0079] Optionally, in some embodiments, a seepage material is disposed in the first through hole 343 .

[0080] Specifically, the seepage material may be a sponge.

[0081] In the embodiment of the present application, the fluid fire extinguishing medium can seep out through the seepage structure 62, which can reduce the rate at which the first fluid fire extinguishing medium flows out of the cavity 31, which is conducive to forming a better fluid curtain 322 on the outer wall of the partition plate 30, making the fluid curtain 322 more uniform, and also can prolong the existence time of the medium layer 321 in the partition plate 30, thereby improving the partition effect.

[0082] Optional, see Figure 6 In some embodiments, the battery cluster 21 includes a plurality of stacked single batteries 211; Fig.14 When the first through hole 343 is located opposite to the single battery 211 , the first through hole 343 is close to the aperture of one side of the single battery 211 and is smaller than the aperture of the other side of the first through hole 343 .

[0083] Specifically, in the event of a fire in the energy storage container, a first fluid fire extinguishing medium is injected into the cavity 31 through the fluid delivery pipe 51. After the first fluid fire extinguishing medium overflows the movable sealing plate 341, the movable sealing plate 341 flips toward the opening 32 under the action of buoyancy to seal the opening 32. Under the action of pressure, the first fluid fire extinguishing medium is sprayed along the c1 direction through the first through hole 343 to spray the first fluid fire extinguishing medium toward the nearest single battery 211 to improve the fire extinguishing effect.

[0084] In the embodiment of the present application, in the case of a fire in the energy storage container, since the first through hole 343 is relative to the single battery 211, the aperture of the first through hole 343 on one side close to the single battery 211 is smaller than the aperture of the other side of the first through hole 343, so that the first through hole 343 relative to the single battery 211 acts as a jet opening 32, and under the action of pressure, the first fluid fire extinguishing medium is sprayed toward the nearest single battery 211, thereby improving the fire extinguishing effect.

[0085] Optional, see Fig. 9 In some embodiments, a main air extraction pipe 35 is provided in the cavity 31, and the main air extraction pipe 35 is connected to the first air suction component 33; Fig.11 The opening 32 is provided with a branch exhaust pipe 36, and the branch exhaust pipe 36 passes through the first through hole 343 of the movable sealing plate 341 of the opening 32; one end of the branch exhaust pipe 36 is open and extends out of the opening 32, and the branch exhaust pipe 36 is connected to the main exhaust pipe 35; the first suction component 33 is also used to absorb the gas through the main exhaust pipe 35 and the branch exhaust pipe 36.

[0086] It should be noted that a gap is provided between the main air extraction pipe 35 and the opening 32 .

[0087] The gas generated by the fire usually contains flammable gases. For example, the single cell 211 may be a lithium battery. Under extreme conditions (such as overheating, impact or short circuit), the lithium battery will experience thermal runaway and release toxic or flammable gases such as hydrogen, carbon monoxide and methane. The flammable gas will drift irregularly during the fire extinguishing process, causing sudden combustion in other locations of the energy storage container, making the fire more serious.

[0088] In the embodiment of the present application, when the energy storage container is not on fire, the vacuum pump 332 continues to work, the movable sealing plate 341 is opened, and the opening 32 and the branch vacuum pipe 36 are simultaneously vacuumed, which can ensure the rapid identification of smoke; when the energy storage container is on fire, the first fluid fire extinguishing medium (such as water) is injected into the cavity 31 through the fluid delivery pipe 51. After the first fluid fire extinguishing medium overflows the movable sealing plate 341, the movable sealing plate 341 flips toward the opening 32 under the action of buoyancy to block the opening 32, thereby preventing a large amount of water from overflowing at one time. At the same time, the vacuum pump 332 The air pump 332 continues to work, so that the branch exhaust pipe 36 continues to exhaust gas, and then after the single battery 211 in the battery cluster 21 burns to produce flammable gas, the flammable gas can be promptly extracted from the nearest branch exhaust pipe 36 to prevent the flammable gas from burning at this high-temperature position and the flammable gas from drifting to other positions of the energy storage container and suddenly forming a combustion. The extracted flammable gas moves upward through the main exhaust pipe 35, and the main exhaust pipe 35 is immersed in the first fluid fire extinguishing medium of the cavity 31, so that the flammable gas can be effectively cooled to further prevent the flammable gas from burning.

[0089] In some embodiments, the first through hole 343 is arranged in the middle of the movable sealing plate 341, and the branch exhaust pipe 36 passes through the seepage material in the first through hole 343. The seepage material is sponge. When the movable sealing plate 341 swings, the seepage material can adaptively deform without affecting the sealing effect of the opening 32.

[0090] Optional, see Fig.15 One end of the branch exhaust pipe 36 extending out of the opening 32 is higher than the end of the branch exhaust pipe 36 connected to the main exhaust pipe 35 .

[0091] In the embodiment of the present application, since one end of the branch exhaust pipe 36 extends out of the opening 32 and is higher than the end of the branch exhaust pipe 36 connected to the main exhaust pipe 35, that is, the branch exhaust pipe 36 is inclined, and the end of the branch exhaust pipe 36 away from the main exhaust pipe 35 is inclined upward, the movable sealing plate 341 is slidably installed on the branch exhaust pipe 36. Since the buoyancy of the movable sealing plate 341 in the first fluid fire extinguishing medium is greater than the gravity of the movable sealing plate 341, when the energy storage container is not on fire, the movable sealing plate 341 turns away from the air hole and turns over along the branch exhaust pipe 36 under the action of its own weight. When the energy storage container is on fire, the first fluid fire extinguishing medium (such as water) is injected into the cavity 31 through the fluid delivery pipe 51. After the first fluid fire extinguishing medium overflows the movable sealing plate 341, the movable sealing plate 341 turns over toward the opening 32 along the branch exhaust pipe 36 under the action of buoyancy to seal the opening 32.

[0092] Optionally, in some embodiments, the movable sealing plate 341 is further provided with a second through hole 344; wherein, when the first fluid fire extinguishing medium flows into the cavity 31 of the partition plate 30, all or part of the holes of the second through hole 344 overlap with the holes of the opening 32.

[0093] In the embodiment of the present application, when the first fluid fire extinguishing medium flows into the cavity 31 of the partition plate 30, the upper side of the movable sealing plate 341 is fitted with the upper side of the opening 32, so that all or part of the holes of the second through hole 344 overlap with the holes of the opening 32 to block part of the holes of the opening 32, thereby reducing the rate at which the first fluid fire extinguishing medium flows out of the cavity 31.

[0094] Optionally, in some embodiments, a seepage material is disposed in the second through hole 344 .

[0095] Specifically, the seepage material may be a sponge.

[0096] In the embodiment of the present application, when the first fluid fire extinguishing medium flows into the cavity 31 of the partition plate 30, the upper side of the movable sealing plate 341 is fitted with the upper side of the opening 32, so that all or part of the holes of the second through hole 344 overlap with the holes of the opening 32 to block part of the holes of the opening 32, and the first fluid fire extinguishing medium seeps out of the cavity 31 through the seepage material, which can reduce the rate at which the first fluid fire extinguishing medium flows out of the cavity 31.

[0097] Optionally, in some embodiments, a main exhaust pipe 35 is provided in the cavity 31, and the main exhaust pipe 35 is connected to the first exhaust component 33; the opening 32 is provided with a branch exhaust pipe 36, and the branch exhaust pipe 36 passes through the opening 32; one end of the branch exhaust pipe 36 is open and extends out of the opening 32, and the branch exhaust pipe 36 is connected to the main exhaust pipe 35; the first exhaust component 33 is also used to absorb the gas through the main exhaust pipe 35 and the branch exhaust pipe 36.

[0098] In the embodiment of the present application, when the energy storage container is not on fire, the vacuum pump 332 continues to work, and the opening 32 and the branch vacuum pipe 36 are simultaneously exhausted, which can ensure the rapid identification of smoke; when the energy storage container is on fire, the first fluid fire extinguishing medium (such as water) is injected into the cavity 31 through the fluid delivery pipe 51, and the vacuum pump 332 continues to work, so that the branch vacuum pipe 36 continues to exhaust air, and then when the single battery 211 in the battery cluster 21 burns to produce flammable gas, the flammable gas can be promptly extracted from the nearest branch vacuum pipe 36 to avoid the flammable gas from burning at this high temperature position and the flammable gas from drifting to other positions of the energy storage container and suddenly forming combustion, and the extracted flammable gas moves upward through the main vacuum pipe 35, and the main vacuum pipe 35 is immersed in the first fluid fire extinguishing medium of the cavity 31, so that the flammable gas can be effectively cooled, and the combustion of the flammable gas can be further avoided.

[0099] Reference Fig.13 In some embodiments, when the energy storage container is on fire, a first fluid fire extinguishing medium is injected into the cavity 31 through the fluid delivery pipe 51. Under the action of the vacuum pump 332, the gas enters along the b1 direction through the branch vacuum pipe 36, moves upward through the main vacuum pipe 35, and then enters the gas collecting pipe 331, and is transported by the gas collecting pipe 331 to the detection component 40 for detection and identification.

[0100] Optionally, in some embodiments, the energy storage container further includes a second storage tank; the second storage tank is provided with a second air suction component, the second air suction component is connected to the first air suction component 33, and the second air suction component is used to draw the gas absorbed by the first air suction component 33 into the second storage tank when the detection result includes that the gas contains the target gas.

[0101] Specifically, the target gas may be flammable or harmful gas.

[0102] In some embodiments, the second air intake assembly is also connected to the space outside the energy storage container and can discharge gas to the outside. For example, when the temperature of the space outside the energy storage container is low, the gas is discharged to the outside through the second air intake assembly to avoid the second storage tank being full and to avoid high-temperature combustion of flammable gases in the gas.

[0103] Specifically, the second air intake component includes an air intake pipe, which is provided with a pump for extracting air. The air intake pipe is respectively connected to the inner cavity of the second storage tank and the gas collecting pipe 331 in the first air intake component 33. Under the action of the pump for extracting air, the gas absorbed by the first air intake component 33 is sucked into the second storage tank.

[0104] In the embodiment of the present application, when the detection result of the second air suction component includes that the gas contains the target gas, the gas absorbed by the first air suction component 33 is pumped into the second storage tank, thereby preventing the target gas from diffusing in the energy storage container.

[0105] Optional, see Fig. 9 In some embodiments, a collecting chamber 37 is provided on the top of the partition plate 30; the collecting chamber 37 is provided with a partition 373, and the partition 373 divides the collecting chamber 37 into a first chamber 371 and a second chamber 372, the first chamber 371 is connected to the first air suction component 33, and the second chamber 372 is connected to the fluid delivery pipe 51; the main exhaust pipe 35 passes through the partition 373 and is connected to the first chamber 371; the partition 373 is provided with a third through hole 374, and a floating plug 375 is provided outside the third through hole 374, and the floating plug 375 is used to open the third through hole 374 when there is residual space in the second chamber 372, and to block the third through hole 374 when the first fluid fire extinguishing medium fills the second chamber 372.

[0106] It should be noted that the buoyancy of the floating plug 375 in the first fluid fire extinguishing medium is greater than the gravity of the floating plug 375 .

[0107] In the embodiment of the present application, when there is residual space in the second cavity 372, the third through hole 374 is opened by the floating plug 375, and under the action of the vacuum pump 332, the air in the second cavity 372 is evacuated through the third through hole 374. Under the action of air pressure, the rate of injecting the first fluid fire extinguishing medium into the cavity 31 is increased; when the first fluid fire extinguishing medium fills the second cavity 372, the cavity 31 is filled with the first fluid fire extinguishing medium, and the third through hole 374 is blocked by the floating plug 375, so that the air collecting pipe 331 is separated from the opening 32, and the air pressure is concentrated in the branch exhaust pipe 36 and the main exhaust pipe 35 for exhaust, and the first fluid fire extinguishing medium is prevented from entering the air collecting pipe 331.

[0108] Optional, see Fig.10 In some embodiments, a collection pool 38 is provided at the lower portion of the partition plate 30, and the collection pool 38 is used to collect the first fluid fire extinguishing medium flowing out of the partition plate 30; the energy storage container also includes a recovery component, which is connected to the collection pool 38 and the first storage tank 50 respectively, and the recovery component is used to transport the first fluid fire extinguishing medium in the collection pool 38 to the first storage tank 50.

[0109] In the embodiment of the present application, the first fluid fire extinguishing medium in the collection pool 38 is transported to the first storage tank 50 through the recovery component, thereby recovering the first fluid fire extinguishing medium flowing down from the partition plate 30, and the first fluid fire extinguishing medium is recovered back into the first storage tank 50 for recycling.

[0110] Optionally, in some embodiments, the recovery component includes a recovery pipe 381, and the recovery pipe 381 is provided with a mechanical pump; the recovery pipe 381 is connected to the collection pool 38 and the first storage tank 50 respectively.

[0111] In the embodiment of the present application, under the action of a mechanical pump, the first fluid fire extinguishing medium in the collection pool 38 is transported to the first storage tank 50 through the recovery pipe 381 , thereby recovering the first fluid fire extinguishing medium flowing down from the partition plate 30 .

[0112] Optionally, in some embodiments, the fluid delivery pipe 51 is provided with a fire interface, and the fire interface is used to communicate with an external fire pipe.

[0113] It should be noted that a fire pipe docking device is provided on the box body 10 of the energy storage container, and the fire pipe docking device is used to connect with an external fire pipe (such as a fire water pipe) so as to connect to a fire hydrant to spray water when necessary to extinguish a fire in the energy storage container.

[0114] In an embodiment of the present application, the fire-fighting interface of the fluid delivery pipe 51 can be connected to a fire-fighting pipe docking device, and connected to an external fire-fighting pipe through the fire-fighting pipe docking device, so as to provide more first fluid fire-fighting medium (such as water) through the external fire-fighting pipe. When the first fluid fire-fighting medium is insufficient in the inner cavity of the first storage tank 50, the first fluid fire-fighting medium is replenished to ensure the continuity of the fire-fighting operation.

[0115] Optional, see Figure 5 In some embodiments, the energy storage container further includes a plurality of fire extinguishing components 39; the fire extinguishing components 39 are disposed on the partition plate 30, and the fire extinguishing components 39 are used to perform a fire extinguishing operation on the energy storage container when the detection result includes a result indicating that the energy storage container is on fire.

[0116] In the embodiment of the present application, when the detection result includes a result indicating that the energy storage container is on fire, the fire extinguishing component 39 performs a fire extinguishing operation on the energy storage container, so that the exploded or burning battery cluster 21 can be extinguished.

[0117] Optional, see Figure 1In some embodiments, the energy storage container further includes a fluid fire extinguishing device 60 and a main delivery pipe 61, wherein the fluid fire extinguishing device 60 is arranged on the box body 10; the fire extinguishing assembly 39 includes a plurality of branch delivery pipes 391, each of which is provided with at least one fire extinguishing nozzle 392; in the fire extinguishing assembly 39 of the partition board 30, each of the branch delivery pipes 391 is arranged on the partition board 30; the main delivery pipe 61 is connected to each of the branch delivery pipes 391; the fluid fire extinguishing device 60 is connected to the main delivery pipe 61, and the fluid fire extinguishing device 60 is used to store a second fluid fire extinguishing medium, and when the detection result includes a result indicating that the energy storage container is on fire, the second fluid fire extinguishing medium is transported through the main delivery pipe 61 and the branch delivery pipe 391, and the second fluid fire extinguishing medium is sprayed through the fire extinguishing nozzle 392.

[0118] Specifically, when the detection result includes a result indicating that the energy storage container is on fire, the fire extinguishing nozzle 392 is triggered to open at the same time, and the second fluid fire extinguishing medium is sprayed through the fire extinguishing nozzle 392; the second fluid fire extinguishing medium may be perfluoroacetone.

[0119] In the embodiment of the present application, when the detection result includes the result indicating that the energy storage container is on fire, the fluid fire extinguishing device 60 delivers the second fluid fire extinguishing medium through the main delivery pipe 61 and the branch delivery pipe 391, and sprays the second fluid fire extinguishing medium through the fire extinguishing nozzle 392, so as to centrally extinguish the exploded or burning battery cluster 21. At the same time, the partition plate 30 cooperates with the partition protection of two adjacent battery clusters 21 to ensure that the fire caused by the accidentally exploded or burned battery cluster 21 will not spread to other battery clusters 21, thereby improving the fire extinguishing efficiency and reducing asset losses.

[0120] Optionally, in some embodiments, at least one branch delivery pipe 391 is provided on the top of each surface of the partition plate 30 .

[0121] In the embodiment of the present application, since at least one branch delivery pipe 391 is provided on the top of each surface of the partition plate 30, the battery clusters 21 on both sides of the partition plate 30 can be extinguished through the fire extinguishing nozzles 392 on the branch delivery pipes 391 on each surface of the partition plate 30.

[0122] Optionally, in some embodiments, each of the branch delivery pipes 391 is provided with a second control valve.

[0123] In the embodiment of the present application, since each branch delivery pipe 391 is provided with a second control valve, it is possible to open the second control valve of the branch delivery pipe 391 near the fire when the energy storage container catches fire, so that the fire extinguishing nozzle 392 on the branch delivery pipe 391 near the fire can accurately extinguish the fire.

[0124] Optional, see Figure 7 In some embodiments, the first air suction component 33 includes an air collecting pipe 331, and the air collecting pipe 331 is provided with an air pump 332; the air collecting pipe 331 is arranged on the top of the partition plate 30, the first end of the air collecting pipe 331 is connected to the cavity 31, and the second end of the air collecting pipe 331 is arranged at the detection component 40.

[0125] In the embodiment of the present application, the vacuum pump 332 continuously pumps air to form an airflow inside the hollow partition plate 30 (i.e., inside the cavity 31), and then pumps air from both sides of the partition plate 30 through the openings 32 on both sides of the partition plate 30. A plurality of openings 32 are evenly distributed on each side of the partition plate 30. In the event that any single battery 211 of the battery cluster 21 accidentally explodes or burns and catches fire, the gas generated by the fire (such as flammable gas or smoke) is absorbed by the opening 32, and the gas is quickly pumped to the detection component 40 for detection and identification, thereby improving the detection and identification efficiency, accelerating the firefighting response speed, and extinguishing the fire in time.

[0126] At the same time, the energy storage container is also provided with an air conditioning system. The vacuum pump 332 can work continuously. In the absence of a fire, the hot air between two adjacent battery clusters 21 can be extracted through the cavity 31 and the air holes of the partition plate 30. In conjunction with the air conditioning system provided in the energy storage container, the air conditioning system replenishes low-temperature air between two adjacent battery clusters 21 with the help of pipelines, thereby achieving temperature control of the battery clusters 21, reducing overheating of the battery clusters 21, and further reducing the probability of fire.

[0127] In some embodiments, each partition plate 30 has a corresponding detection component 40, and the detection component 40 can be set on the top of the box body 10 or on the partition plate 30 corresponding to the detection component 40; the detection component 40 corresponding to the partition plate 30 detects the gas in the area on both sides of the partition plate 30, obtains the detection results of the area on both sides of the partition plate 30, and displays the alarm information of the battery cluster 21 fire near the partition plate 30 when the detection results of the area on both sides of the partition plate 30 include the results of characterizing the battery cluster 21 fire near the partition plate 30, so as to timely discover and deal with the fire, thereby reducing the risk of scrapping the energy storage container. At the same time, the first control valve 52 corresponding to the partition plate 30 near the fire is opened, so that the first fluid fire extinguishing medium of the first storage tank 50 flows into the cavity 31 of the partition plate 30 near the fire, and passes through Fluid flows out of the opening 32 of the partition plate 30 near the fire source, and a medium layer 321 can be formed in the cavity 31 of the partition plate 30, and a fluid curtain 322 can be formed on the outer sides of the two surfaces of the partition plate 30, thereby isolating the battery cluster on fire from other battery clusters that have not caught fire, which is beneficial to preventing the spread of fire; in addition, the second control valve of the branch delivery pipe 391 of the partition plate 30 near the fire source is opened, and the second fluid fire extinguishing medium in the fluid fire extinguishing device 60 is delivered to the fire extinguishing nozzle 392 through the main delivery pipe 61 and the branch delivery pipe 391, so that the fire extinguishing nozzle 392 on the branch delivery pipe 391 of the partition plate 30 near the fire source sprays the second fluid fire extinguishing medium, and accurately extinguishes the fire at the fire source, thereby avoiding the scrapping of the battery cluster that has not caught fire due to the spraying of the second fluid fire extinguishing medium on the battery cluster that has not caught fire while extinguishing the fire.

[0128] In some embodiments, a temperature sensor is provided at each single cell 211. When the temperature sensor detects that the temperature of the single cell 211 is too high, and the detection result of the detection component 40 corresponding to the partition plate 30 near the single cell 211 with too high temperature includes a result indicating that the battery cluster 21 near the partition plate 30 is on fire, an alarm information of the fire of the battery cluster 21 near the partition plate 30 is displayed and precise fire extinguishing operations are performed at the fire site.

[0129] Reference Figure 8 In some embodiments, under the action of the vacuum pump 332, the gas enters through the opening 32 along the direction a1, moves upward along the direction a2 through the cavity 31, and then enters the gas collecting pipe 331, and is transported by the gas collecting pipe 331 to the detection component 40 for detection and identification.

[0130] Optionally, in some embodiments, each surface of the partition plate 30 is provided with a plurality of the openings 32 ; on each surface of the partition plate 30 , the openings 32 are arranged in a matrix form.

[0131] Specifically, the openings 32 are evenly distributed on all surfaces of each partition plate 30 , thereby increasing the distribution area of ​​the fluid curtain 322 .

[0132] In the embodiment of the present application, since the openings 32 are arranged in a matrix form on each surface of the partition plate 30 , the uniformity of the fluid curtain 322 is improved.

[0133] In the related art, each battery cluster 21 is tightly fitted together. When a single battery 211 in a battery cluster 21 accidentally explodes or burns, it is easy to ignite the two battery clusters adjacent to the exploded or burning single battery 211, causing the fire to spread faster. In the actual fire-fighting process, since there is no fire-fighting space between adjacent battery clusters 21, the actual fire-fighting effect is poor, causing great losses.

[0134] In the embodiment of the present application, a partition plate 30 is provided between adjacent battery clusters 21, which can effectively prevent the exploded or burning single battery 211 from igniting two adjacent battery clusters, delay the spread of fire, and have a partition plate 30 between adjacent battery clusters 21, thereby increasing the fire extinguishing space and improving the fire extinguishing effect.

[0135] In the related art, a smoke sensor is installed above the container. In the event that a battery cell at the lowest position accidentally explodes or burns and catches fire, the gas generated by the fire needs to float freely to the top before it can be recognized by the smoke sensor. The delayed recognition of the smoke sensor causes delayed firefighting processing and affects the firefighting effect.

[0136] In the embodiment of the present application, the first air suction component 33 absorbs the gas in the box body 10 through the cavity 31 and the plurality of openings 32 of the partition plate 30, and transports the gas to the detection component 40, and then the gas is detected by the detection component 40 to obtain the detection result, and when the detection result includes a result representing a fire in the energy storage container, an alarm message is displayed. In this process, since the first air suction component 33 can shorten the time for the gas to reach the detection component 40, the detection efficiency is improved, the fire is discovered and handled in time, and the risk of scrapping the energy storage container is reduced.

[0137] Reference Fig.16 The embodiment of the present application provides a fire-fighting method for an energy storage container, which is applied to the aforementioned energy storage container, and the method includes:

[0138] Step 101: The first air intake component absorbs the gas in the box through the cavity and the plurality of openings, and delivers the gas to the detection component.

[0139] The specific implementation process of this step is similar to the implementation process of the aforementioned energy storage container, and will not be repeated here.

[0140] Step 102: Detect the gas by the detection component to obtain a detection result, and display an alarm message when the detection result includes a result indicating that the energy storage container is on fire.

[0141] The specific implementation process of this step is similar to the implementation process of the aforementioned energy storage container, and will not be repeated here.

[0142] Through the embodiments of the present application, it is possible to ensure that there is sufficient partition space between each battery cluster 21, and the speed of the detection component 40 in identifying a fire can be increased, the targeted fire extinguishing effect on the burning battery cluster 21 can be improved, and the fire can be prevented from spreading to other battery clusters 21, thereby reducing asset losses.

[0143] To summarize, in the embodiment of the present application, the first air suction component 33 absorbs the gas in the box body 10 through the cavity 31 and the plurality of openings 32 of the partition plate 30, and transports the gas to the detection component 40, which then detects the gas to obtain the detection result, and displays an alarm message when the detection result includes a result indicating that the energy storage container is on fire. In this process, the first air suction component 33 can shorten the time it takes for the gas to reach the detection component 40, thereby improving the detection efficiency, so that the fire can be discovered and handled in a timely manner, thereby reducing the risk of scrapping the energy storage container.
