In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application, but the present application may be practiced otherwise than as described herein; it will be apparent that the embodiments in the specification are only some, but not all, embodiments of the application.

Referring to fig. 1, fig. 1 is a schematic diagram of an energy storage battery fire protection system according to some embodiments of the present application. The embodiment of the application provides an energy storage battery fire protection system 100, and the energy storage battery fire protection system 100 can comprise an energy storage module 1, a storage module 2, a spraying module 3, a conveying module 4 and a control module 5.

The energy storage module 1 may be formed in a shape of a cube, a cylinder, etc., to which the present application is not limited. The accommodation space 11 may be a completely closed space, or the accommodation space 11 may be a partially closed or completely open space, for example, the accommodation space 11 may have an opening communicating with the outside of the energy storage module 1.

A battery 12 may be provided in the accommodation space 11. By way of example, the energy storage module 1 may be an area of the production process of the battery 12, such as a workshop, loading dock, test bed, warehouse, shelf, shed, test line.

The battery 12 may be a battery 12 under production, a battery 12 under test, a battery 12 under charge and discharge, a battery 12 under standing, a battery 12 under formation or pre-formation, a battery 12 under storage, or the like.

The storage module 2 is disposed outside the energy storage module 1, i.e. the storage module 2 is located in the external space. Therefore, the problem that fire disaster occurs in the energy storage module 1 to enable the storage module 2 to not normally provide fire extinguishing medium can be avoided, the reliability of the storage module 2 can be improved, and the fire fighting capability of the energy storage battery fire fighting system 100 can be guaranteed.

The extinguishing medium may comprise one or more of Nitrogen (Nitrogen) or Argon (Argon). Specifically, the fire extinguishing medium may be nitrogen, or may be argon, or may be nitrogen and argon. Therefore, the air in the energy storage module 1 can be cooled and inerted through the fire extinguishing medium, so that the ignition of the energy storage module 1 can be avoided, the problem of the accumulation of flammable and explosive gas generated in the ignition process of the battery 12 can be solved, the explosion risk caused by the flammable and explosive gas can be prevented, and the fire fighting capability of the energy storage battery fire fighting system 100 can be improved. At the same time, the nitrogen and argon can avoid damaging the battery 12, and the loss of the user can be reduced, thereby being beneficial to improving the use experience of the user. In addition, since nitrogen and argon can return to the external space after the energy storage module 1 is ventilated, the energy storage module 1 can be immediately restored to operation after the fire extinguishing is completed.

The fire extinguishing medium stored in the storage container 21 may be a liquid fire extinguishing medium, a gaseous fire extinguishing medium, or a gas-liquid fire extinguishing medium. For example, the extinguishing medium may be gaseous nitrogen, liquid nitrogen or gaseous liquid nitrogen, or may be gaseous argon, liquid argon or gaseous liquid argon. The fire extinguishing medium stored in the storage container 21 is mainly liquid fire extinguishing medium, and the storage capacity can be designed according to the amount of fire fighting required by the energy storage module 1.

The transport module 4 may include an internal transport conduit 41 and a recovery conduit 44. One end of the internal transport pipe 41 communicates with the storage container 21. One end of the recovery conduit 44 is also in communication with the storage vessel 21. Thereby, the extinguishing medium in the storage container 21 can enter the inner transport pipe 41. The extinguishing medium in the recovery pipe 44 can flow back into the storage container 21.

The transport module 4 may also comprise a recycling device 45. The recovery device 45 may drive the extinguishing medium back into the storage container 21. Thereby, the ability of the energy storage battery fire protection system 100 to recover fire extinguishing medium is advantageously improved.

The spray module 3 may include an inner spray 31 and a recovery 32. The inner spouting member 31 and the recovering member 32 are both disposed in the accommodating space 11, and are both located inside the battery 12. The inner spraying member 31 is connected with the other end of the inner conveying passage such that the fire extinguishing medium stored in the storage container 21 can flow to the inner spraying member 31 through the inner conveying passage, so that the fire extinguishing medium can be sprayed into the battery 12 through the inner spraying member 31 for fire extinguishing to the inside of the battery 12.

The recovery member 32 is connected to the other end of the recovery pipe 44. Specifically, since the interior of the battery 12 is a closed space, when the fire extinguishing medium is cooled or extinguished, the fire extinguishing medium can be changed from a liquid fire extinguishing medium into a gaseous or gas liquid state, and the endothermic fire extinguishing medium passes through the recovery member 32, and the driving member of the recovery device 45 can flow back into the storage container 21 through the recovery pipeline 44, thereby recovering the fire extinguishing medium, being beneficial to reducing the waste of the fire extinguishing medium and reducing the use cost of the energy storage battery fire-fighting system 100.

The inner spouting member 31 may communicate with the recovery member 32, and the inner spouting member 31 and the recovery member 32 may be located at the outer circumference of the battery 12. Therefore, the recovery piece 32 can directly recover the fire extinguishing medium sprayed by the internal spraying piece 31, and can avoid entering the inside of the battery 12, thereby being beneficial to improving the applicability of the energy storage battery fire protection system 100.

The battery 12 may be provided with an inner spouting member 31 and a recovering member 32 at the outer circumference and the inner portion thereof. Thereby, the fire fighting capability of the energy storage battery fire fighting system 100 may be improved.

For example, the controller 51 may control the inner spray 31 to start operating when the temperature in the battery 12 is higher than the set temperature, and the controller 51 may control the inner spray 31 to stop operating when the temperature in the battery 12 is lower than the set temperature. The inner spray 31 may maintain a preset fire extinguishing time as needed under the control of the controller 51.

According to the energy storage battery fire protection system 100 of the embodiment of the application, by arranging the internal spraying part 31 inside the battery 12 or communicating the internal spraying part 31 with the recovery part 32, the fire of the battery 12 can be directly extinguished or cooled by the internal spraying part 31, which is beneficial to improving the fire protection capability of the energy storage battery fire protection system 100 and the fire extinguishing speed of the battery 12. Meanwhile, by arranging the recovery piece 32, the recovery piece 32 can be communicated with the storage container 21 through the recovery pipeline 44, so that the fire extinguishing medium released by the internal spraying piece 31 can be recycled through the recovery device 45, the fire extinguishing medium can be recycled, the waste of the fire extinguishing medium can be reduced, and the use cost of the energy storage battery fire-fighting system 100 can be reduced. And the fire extinguishing medium can be continuously cooled and isolated in the recycling process. In addition, the fire extinguishing medium stored in the storage container 21 may be one or more of argon or nitrogen, so that the air inside the battery 12 may be inerted by the fire extinguishing medium, and the problem of the accumulation of flammable and explosive gases generated during the ignition process of the battery 12 may be solved, which is advantageous for improving the fire fighting capability of the energy storage battery fire fighting system 100. And the nitrogen and the argon can avoid damaging the battery 12, so that the loss of a user can be reduced, and the use experience of the user is improved. In addition, since nitrogen and argon do not pollute the environment, the environmental protection capability of the energy storage battery fire protection system 100 is improved, and the operation can be resumed immediately after the fire extinguishment is completed.

In some embodiments, the inner spray 31 has a closed loop nozzle. Wherein, the closed-loop nozzle can continuously spray the fire extinguishing medium, and can indirectly spray the fire extinguishing medium. The extinguishing range of the inner spouting member 31 can be enlarged by the closed-loop nozzle, and the extinguishing speed of the inner spouting member 31 can be improved.

Illustratively, the number of internal spouts 31 may be plural. The plurality of inner spouts 31 have a plurality of closed-loop nozzles, which may be operated together or individually, and the present application is not limited thereto. The shape of each closed-loop nozzle can be different and can be reasonably set according to the needs.

The closed-loop nozzle may be in the form of a single hole or may be in the form of multiple holes.

Thereby, the space outside the battery 12 can be extinguished by the external spouting member 33, so that the fire fighting capability of the energy storage battery fire fighting system 100 can be further improved.

In some embodiments, the external spouting member 33 may have an open-loop nozzle, wherein the open-loop nozzle may continuously spout the fire extinguishing medium, or may indirectly spout the fire extinguishing medium. The inerting and replacement of the combustible gas leakage can be realized through the open-loop nozzle, the fire extinguishing function can be realized, the maintaining function of the fire extinguishing concentration can also be realized, and the re-burning of the fire disaster is prevented. And simultaneously, the fire extinguishing range of the external spraying piece 33 can be enlarged, and the fire extinguishing speed of the external spraying piece 33 can be improved.

Illustratively, the number of external spouts 33 may be plural. The plurality of outer spouts 33 have a plurality of open-loop nozzles, which may be operated together or individually, and the present application is not limited thereto.

In some embodiments, the number of batteries 12 may be multiple. The spray module 3 may comprise a plurality of connection channels. Adjacent two cells 12 are connected in parallel through a connection channel. Thus, the mutual interference between the batteries 12 and 12 can be avoided, which is beneficial to improving the reliability and safety of the energy storage battery fire protection system 100.

Referring to fig. 2, fig. 2 is a schematic diagram of an energy storage battery fire protection system according to another embodiment of the application. In other embodiments, two adjacent cells 12 may be in series communication via a connecting channel. Therefore, the mounting and connection are convenient, and the assembly efficiency is improved.

In still other embodiments, two adjacent cells 12 are connected in a combination of series and parallel connection through a connecting channel. Such an arrangement may be designed as desired to improve the fire fighting capabilities of the energy storage battery fire protection system 100.

With continued reference to fig. 2, in some embodiments, the energy storage battery fire protection system 100 may also include a mobile component. The moving assembly is movably disposed in the accommodating space 11. The outer spray 33 is connected to the moving assembly. Thus, the external spraying member 33 can move along with the moving assembly, so that the external spraying member can move to a designated place according to the requirement of the energy storage battery fire protection system 100, and the fire extinguishing accuracy of the energy storage battery fire protection system 100 can be improved.

For example, the moving assembly may include a guide rail, a moving member, and a driving motor. The moving member is slidably coupled to the guide rail. The driving motor drives the moving member to slide on the guide rail, and the external spouting member 33 may be connected to the moving member. Thus, the moving member can drive the external spouting member 33 to move when moving.

With continued reference to fig. 2, in some embodiments, the energy storage battery fire protection system 100 may also include a detection module 6. The detection module 6 may be electrically connected to the controller 51 of the control module 5. The control module 5 comprises a detector 61. The detector 61 is provided in the accommodation space 11. Specifically, the detector 61 may detect one or more of carbon monoxide, hydrogen, smoke, temperature, spark flame, oxygen, etc. in the energy storage module 1, the detector 61 may transmit the detected result to the controller 51, and the controller 51 may control whether the external spray member 33 or the internal spray member 31 sprays the fire extinguishing medium according to the detected result of the detector 61. Therefore, by arranging the detection module 6, various information related to the occurrence of fire in the energy storage module 1 can be detected in time, so that the fire prevention or discovery capability of the energy storage battery fire protection system 100 can be improved, and the energy storage battery fire protection system 100 can prevent or spray fire extinguishing medium to the position where the fire occurs in time.

For example, the detector 61 may be provided both outside the battery 12 and inside the battery 12. Thereby further improving the fire fighting capabilities of the energy storage battery fire protection system 100.

With continued reference to the figures, in some embodiments, the energy storage battery fire protection system 100 further includes a pressure relief module 7. The waster relief module 7 is electrically connected to the controller 51 of the control module 5. The exhaust and pressure relief module 7 may be arranged outside the energy storage module 1 and in communication with the accommodation space 11 in the energy storage module 1. In particular, the pressure relief module 7 may be provided on an outer surface of the energy storage module 1. Since the exhaust and pressure relief module 7 is communicated with the accommodating space 11 in the energy storage module 1, when the pressure value in the energy storage module 1 exceeds the preset pressure value, the controller 51 can control the exhaust and pressure relief module 7 to discharge the gas in the accommodating space 11 into the external space of the energy storage module 1, so that the pressure in the energy storage module 1 can be reduced.

Therefore, when flammable and explosive gases such as carbon monoxide, hydrogen and the like in the energy storage module 1 leak to a certain concentration through the arrangement of the exhaust pressure relief module 7, the internal spraying piece 31 and the external spraying piece 33 are used for diluting and replacing the fire extinguishing medium after discharging the fire extinguishing medium through the exhaust pressure relief module 7, so that the reliability and the safety of fire fighting of the energy storage battery fire extinguishing system 100 can be ensured, and the functions of fire prevention and explosion prevention are achieved. In addition, the controller 51 is electrically connected to the exhaust and pressure relief module 7, so that the degree of intellectualization of the energy storage battery fire protection system 100 can be further improved. In addition, set up the pressure release module 7 outside energy storage module 1, when can avoid energy storage module 1 to take place the conflagration in, make the pressure release module 7 appear damaging to the security that pressure release module 7 used can be guaranteed.

For example, the waster relief module 7 may include a waster relief device that may be electrically connected to the controller 51. Thereby, the pressure value in the energy storage module 1 can be controlled by the exhaust gas pressure relief device.

In other embodiments, the pressure relief module 7 may also be arranged in the receiving space 11 of the energy storage module 1. Thus, protection can be formed on the exhaust and pressure relief module 7 through the energy storage module 1, and the service life of the exhaust and pressure relief module 7 is prolonged.

For example, the pressure relief module 7 may be automatically turned on or off. For example, the pressure relief module 7 may be electronic, and may increase the degree of intelligence. The exhaust and pressure relief module 7 may also be mechanical without consuming electrical energy.

With continued reference to fig. 2, in some embodiments, the delivery module 4 further includes a first valve assembly 42 and a second valve assembly 43. The first valve assembly 42 is electrically connected to the controller 51. The first valve assembly 42 is used to control communication between the reservoir 21 and the spray module 3. Thus, in case of fire in the energy storage module 1, the controller 51 may control the first valve assembly 42 to be opened so that the storage container 21 may communicate with the discharge module 3, thereby allowing the discharge module 3 to extinguish a fire using the fire extinguishing medium in the storage container 21. When the fire is extinguished in the energy storage module 1, the controller 51 may control the first valve assembly 42 to be closed, thereby disconnecting the communication between the storage container 21 and the discharge module 3, and thus reducing the waste of the fire extinguishing medium in the storage container 21.

The second valve assembly 43 is electrically connected to the controller 51. The second valve assembly 43 is used to control the pressure and flow rate of the extinguishing medium output by the delivery module 4. Therefore, the speed and the concentration of the fire extinguishing medium sprayed by the inner spraying part 31 and the outer spraying part 33 can be controlled, so that the energy storage battery fire protection system 100 can accurately release enough fire extinguishing amount according to the fire disaster, thereby being beneficial to improving the intellectualization of the energy storage battery fire protection system 100.

With continued reference to fig. 2, in some embodiments, the first valve assembly 42 includes an on-off valve 421 and a one-way valve 422.

The check valve 422 may also be located on the side of the on-off valve 421 remote from the storage container 21. Accordingly, the reverse flow of the fire extinguishing medium in the inner conveying pipe 41 and the outer conveying pipe 46 can be avoided by providing the check valve 422, which is beneficial to improving the safety of the energy storage battery fire protection system 100. The on-off valve 421 is provided to control the on-off between the storage container 21 and the transport module 4, so that whether the external spouting member 33 or the internal spouting member 31 needs continuous spouting can be controlled.

Illustratively, the on-off valve 421 may be an electronic on-off valve 421. Thus, the degree of intellectualization of the energy storage battery fire protection system 100 may be improved to some extent.

With continued reference to fig. 2, in some embodiments, the storage module 2 may further include a liquefaction device 22, a pressure temperature controller 23, and a pressure temperature detector 24. The liquefaction device 22 may be used to change the state of the extinguishing medium in the storage vessel 21. The pressure temperature controller 23 may be used to control the temperature and pressure within the storage vessel 21. The pressure temperature detector 24 may be used to detect the temperature and pressure within the storage vessel 21. Thus, when the energy storage battery fire extinguishing system 100 needs the liquid fire extinguishing medium, the pressure and the temperature in the storage container 21 can be detected by the pressure temperature detector 24, and the temperature and the pressure in the storage container 21 can be changed by the liquefying device 22 and the pressure temperature controller 23, so that the fire extinguishing medium in the storage container 21 can be converted into the liquid fire extinguishing medium. When gaseous or liquid extinguishing medium is required, the state of the extinguishing medium in the storage vessel 21 can also be changed in the manner described above. Therefore, the storage module 2 can realize two-state homologous supply of the fire extinguishing medium, so that the energy storage battery fire extinguishing system 100 can spray the fire extinguishing medium in different states according to the needs, and the applicability of the energy storage battery fire extinguishing system 100 is improved.

Illustratively, the liquefaction device 22, the pressure temperature controller 23, and the pressure temperature detector 24 may be provided on the storage container 21, so that the storage module 2 may be integrated, and the volume of the storage module 2 may be reduced.

With continued reference to fig. 2, in some embodiments, the storage module 2 further includes an overpressure release device 26, where the overpressure release device 26 is a device that automatically discharges medium after overpressure, reduces pressure, and protects the apparatus and its systems from damage, which is beneficial for increased protection of the storage module 2.

With continued reference to fig. 2, in some embodiments, the storage module 2 further includes a reserve detector 25. The reserve detector 25 is electrically connected to the controller 51. The reserve detector 25 detects a reserve of the storage container 21. Therefore, when the reserve detector 25 detects that the capacity of the fire extinguishing medium in the storage container 21 is smaller than the preset capacity, the user can be reminded to check whether the storage container 21 leaks or not and timely supplement the fire extinguishing medium, so that the problem that the fire extinguishing medium is insufficient when the energy storage battery fire-fighting system 100 is used for extinguishing fire can be avoided, and the fire-fighting capacity of the energy storage battery fire-fighting system 100 can be guaranteed.

In some embodiments, the energy storage battery fire protection system 100 may also include an emergency replenishment module 8. The emergency replenishment module 8 communicates with the storage container 21. The emergency replenishment module 8 serves to replenish the storage container 21 with extinguishing medium. Therefore, when the fire extinguishing medium in the storage container 21 is insufficient, the storage container 21 can be supplemented through the emergency supplementing module 8, so that the problem that the fire extinguishing interruption occurs in the energy storage battery fire protection system 100 can be avoided, and the emergency capability of the energy storage battery fire protection system 100 can be improved.

By way of example, the emergency replenishment module 8 may include a fixed replenishment 81 and a mobile replenishment 82. Wherein the moving supplement 82 may be a tank car and the stationary supplement 81 may be an air separator. The tank car and the air separator can directly prepare the fire extinguishing medium from the external atmosphere.

Referring to fig. 3, fig. 3 is a schematic diagram illustrating an energy storage module and an arrangement of the energy storage module according to some embodiments of the application.
