[0030] In order to better understand the present application, the fire-fighting device 10, the fire-fighting system and the energy storage device of the embodiment of the present application are described in detail below with reference to the accompanying drawings.

[0031] Please also read Figures 1 to 3 , Figure 1 The front structural diagram of the fire fighting device 10 in one embodiment of the present application is shown. Figure 2 and Figure 3 A structural schematic diagram of the back side of a fire fighting device 10 in an embodiment of the present application is shown.

[0032] The embodiment of the present application provides a fire-fighting device 10, including a mounting member 1, a fire-fighting nozzle 2, a valve assembly 3, and a detection controller 4. The mounting member 1 has an edge area A1 and a center area A2, the edge area A1 is used to be connected to the battery pack 30, and the center area A2 is at least partially protruded relative to the edge area A1 along the first direction X to form an installation space S connected to the battery pack 30. The fire-fighting nozzle 2 is connected to the mounting member and includes an electric explosion valve 21 and a connector 22 and a nozzle head 23 arranged on the electric explosion valve 21. A flow channel is formed in the electric explosion valve 21, and the connector 22 is connected to the nozzle head 23 through the flow channel. The nozzle head 23 is used to output a fire-extinguishing medium to the battery pack 30, and the valve assembly 3 is arranged on the flow channel. The detection controller 4 is arranged in the installation space S, and the detection controller 4 controls the on-off of the flow channel and / or the flow rate of the fire-extinguishing medium through the valve assembly 3.

[0033] In the fire-fighting device 10 in the embodiment of the present application, the fire-fighting nozzle 2, the valve assembly 3 and the detection controller 4 are integrated on the mounting member 1. The mounting member 1 has an edge area A1 and a central area A2. The central area A2 is at least partially raised relative to the edge area A1 along the first direction X to form an installation space S. The nozzle head 23 of the fire-fighting nozzle 2 and the detection controller 4 are arranged in the installation space S. When the edge area A1 of the mounting member 1 is connected to the battery pack 30, the detection controller 4 can be connected to the battery pack 30 through the installation space S, so that the risk abnormality characteristics in the battery pack 30 can be detected, and the valve assembly 3 and the fire-fighting nozzle 2 arranged on the mounting member 1 can realize the functions of detection, control and spraying execution. Compared with the existing fire-fighting device 10, the fire-fighting device 10 can be integrated and installed on the outside of the battery pack 30 while meeting the function realization. No electrical or pipeline connection is required in the battery pack 30, the structure is simple, and the installation and maintenance work can be simplified, reducing the installation and maintenance costs.

[0034] It is understandable that by integrating functional components such as the fire nozzle 2, the valve assembly 3, and the detection controller 4 on the mounting member 1, during installation, the fire-fighting device 10 can be installed by simply installing the mounting member 1 on the outside of the battery pack 30, which makes the installation simpler and more convenient, and it is also easier to adjust the installation position of the fire-fighting device 10 on the battery pack 30 according to the use requirements of the battery pack 30, and has strong assembly flexibility. In addition, the fire-fighting device 10 in the present application can also be adapted to various styles of battery packs 30, can be used normally on battery packs 30 of different sizes and models, and can be adapted to various battery packs 30, thereby improving the applicability of the fire-fighting device 10.

[0035] For ease of understanding, the structure of the fire fighting device 10 is further described below in conjunction with various components thereof.

[0036] The mounting member 1 is used as the mounting body of the fire-fighting device 10 to support the fire-fighting nozzle 2, the valve assembly 3 and the detection controller 4. The mounting member 1 includes an edge area A1 and a center area A2. The edge area A1 is connected to the battery pack 30, and the center area A2 is at least partially protruded relative to the edge area A1 along the first direction X to a side away from the battery pack 30, so that after the edge area A1 is connected to the battery pack 30, an installation space S connected to the battery pack 30 can be at least partially formed in the center area A2. The first direction X can be set to the thickness direction of the mounting member 1 itself.

[0037] Optionally, the edge area A1 is arranged to surround the periphery of the central area A2, so that after the edge area A1 is connected to the battery pack 30, the sealing of the installation space S can be improved to protect the functional components in the fire fighting device 10 and increase the structural stability of the functional components. As an example, the edge area A1 and the central area A2 can be arranged as an integrated structure, for example, by stamping, so that the central area A2 is raised relative to the edge area A1, and the manufacturing process is simpler and more reliable.

[0038] Optionally, the mounting member 1 can be detachably connected to the housing of the battery pack 30. Specifically, the mounting member 1 can be connected to the housing of the battery pack 30 by fasteners such as bolts, studs, and screws, which is convenient for assembly and disassembly, and the connection is reliable. Exemplarily, the mounting member 1 can be set at a position of the housing of the battery pack 30 close to the battery cells inside it to ensure that the fire extinguishing medium sprayed by the fire fighting device 10 can cover all the battery cells in the battery pack 30, thereby improving the fire extinguishing effect of the fire fighting device 10 and improving safety.

[0039] The fire nozzle 2 is connected to the mounting part 1 and includes an electric explosion valve 21, a joint 22 and a nozzle head 23. The fire extinguishing medium can enter the flow channel in the electric explosion valve 21 through the joint 22. The electric explosion valve 21 explodes and flows out the fire extinguishing medium after being triggered. The fire extinguishing medium is sprayed into the battery pack 30 by the nozzle head 23 to extinguish the fire in the battery pack 30. Among them, the connection position of the fire nozzle 2 on the mounting part 1 can be adjusted according to the specific structure of the mounting part 1 to ensure that the fire extinguishing agent can cover all battery cells in the battery pack 30 and improve the fire extinguishing effect.

[0040] Optionally, the connector 22 is configured as a quick connector 22. By configuring the connector 22 as a quick connector 22, quick connection is achieved, which is convenient for assembly, helps improve assembly and disassembly efficiency, and also helps improve maintenance efficiency. The nozzle pipe interface uses a quick plug connector 22, which makes it more convenient and quick to connect with the external guide pipe, thereby improving installation efficiency. Optionally, the quick connector 22 includes a plug-in connector 22, and of course, the quick connector 22 also includes a screw connector 22, both of which can achieve quick connection.

[0041] In addition, the connector 22 can be connected to a device storing a fire extinguishing medium to achieve a fire-fighting connection with the battery pack 30, so that the fire-fighting medium can enter the flow channel of the fire nozzle 2 through the connector 22. When assembling or replacing the fire-fighting device 10, the connection can be disconnected by simply unplugging the quick connector 22, which is simple to operate, convenient for assembly and maintenance, and helps to improve disassembly and assembly efficiency and reduce labor costs.

[0042] Optionally, the shape of the nozzle head 23 can be set to a circular, square or other shape, which is not limited in the present application. The nozzle head 23 can spray out the atomized fire extinguishing medium, and the nozzle head 23 can use any existing nozzle head 23 capable of atomizing spraying, so that the fire extinguishing medium can be evenly sprayed on the battery pack 30, forming a reliable fire extinguishing coverage area and improving the fire fighting efficiency.

[0043] The valve assembly 3 is arranged on the flow channel, and the valve assembly 3 serves as a trigger device of the electric explosion valve 21, and is used to receive the fire signal output by the detection controller 4. When a fire occurs, the valve assembly 3 can respond to the signal of the fire occurrence in time, and trigger the electric explosion valve 21 to open the electric explosion valve 21, so that the flow channel in the electric explosion valve 21 is connected, so as to ensure that the fire extinguishing medium can quickly flow into the nozzle head 23, and the flow rate of the fire extinguishing medium can be controlled to improve the fire fighting efficiency.

[0044] The detection controller 4 is connected to the mounting member 1 and is disposed in the mounting space S. The detection controller 4 can be connected to the valve assembly 3 through a signal line. The detection controller 4 is used to detect the risk abnormality characteristics of the battery pack 30, so that when the battery pack 30 is abnormal and there is a fire risk, a fire signal can be issued in time to control the valve assembly 3 to complete the triggering of the electric explosion valve 21.

[0045] Optionally, the detection controller 4 can be set as an all-in-one detection controller 4, which can detect abnormal dangerous factors such as temperature, smoke, combustible gas (including but not limited to hydrogen, carbon monoxide, alkanes), organic volatiles (including but not limited to VOC pollutants) in the battery pack 30 through the detection controller 4.

[0046] Specifically, in the fire-fighting device 10 in the embodiment of the present application, when there is a fire risk in the battery pack 30, the fire-fighting device 10 has the following fire-fighting process: the detection controller 4 can automatically detect abnormal dangerous factors and send a fire-fighting signal to the valve assembly 3; the valve assembly 3 can respond to the signal of the fire in a timely manner and trigger the electric explosion valve 21 to open the electric explosion valve 21, so that the flow channel in the electric explosion valve 21 is connected, so as to ensure that the fire-fighting medium can quickly flow into the nozzle head 23, and then be sprayed out through the nozzle head 23 to atomize and spray the battery pack 30, so as to timely extinguish the fire in the battery pack 30, which is conducive to improving the fire-fighting efficiency and improving safety.

[0047] It can be understood that since the fire nozzle 2, valve assembly 3 and detection controller 4 are all arranged on the mounting member 1, the positions of the above-mentioned functional components on the mounting member 1 can be reasonably arranged to improve the compactness of the component layout while satisfying the functional realization of the fire-fighting device 10.

[0048] For the fire nozzle 2, it includes an electric explosion valve 21 and a connector 22 and a nozzle head 23 arranged on the electric explosion valve 21. The connector 22 needs to extend to the outside of the installation space S to connect to the external guide pipe, and the nozzle head 23 needs to be arranged in the installation space S to spray the fire extinguishing medium into the battery pack 30. For the electric explosion valve 21, it can be arranged in the installation space S or outside the installation space S.

[0049] See also Figures 1 to 3 In some optional embodiments, when the electric explosion valve 21 is disposed in the installation space S, a first interface 11 is provided on the installation member 1, and the connector 22 extends out of the installation space S through the first interface 11.

[0050] By arranging both the electric explosion valve 21 and the detection controller 4 in the installation space S, and only extending the connector 22 from the first interface 11 outside the installation space S to connect to the external guide tube, after the mounting member 1 is connected to the battery pack 30, the electric explosion valve 21 and the detection controller 4 can be protected by the mounting member 1, the reliability is higher, and the fire-fighting device 10 is more beautiful when viewed from the outside of the battery pack 30.

[0051] Optionally, a mounting back plate is provided outside the electric explosion valve 21 for positioning and mounting thereof, and also serves as a seal.

[0052] In some optional embodiments, a partition 12 is provided on a side surface of the central area A2 facing the installation space S, and the partition 12 divides the installation space S along the second direction Z to form a plurality of subspaces for accommodating the electric explosion valve 21 and the detection controller 4. The second direction Z intersects with the first direction X.

[0053] Since the electric explosion valve 21 and the detection controller 4 are both arranged in the installation space S, the installation space S can be divided into multiple sub-spaces by arranging a partition 12 on the mounting member 1, which is more convenient for positioning and installing the electric explosion valve 21 and the detection controller 4, improves the reliability of the fire-fighting device 10, and also makes the electric explosion valve 21 and the detection controller 4 arranged more compactly to save space.

[0054] Optionally, the second direction Z can be the height direction of the mounting member 1. In the second direction Z, the electric explosion valve 21 can be arranged above the detection controller 4, and the layout is reasonable, which is conducive to improving the compactness of the structure of the fire-fighting device 10. Of course, the fire-fighting nozzle 2 and the detection controller 4 can also be other structural layout forms.

[0055] In some optional embodiments, the fire fighting device 10 further includes a first seal 5, and the first seal 5 at least partially covers the outer periphery of the valve assembly 3. That is, since the electric explosion valve 21 is arranged in the installation space S, the valve assembly 3 is also correspondingly arranged in the installation space S, so by providing the first seal 5, the valve assembly 3 can be closed by the first seal 5, thereby reducing the risk of the released flammable gas, high temperature, open flame, etc. invading the battery pack 30 when the valve assembly 3 fails abnormally.

[0056] Optionally, the first sealing member 5 may be configured as a potting compound.

[0057] Optionally, the partition 12 can divide the installation space S into a first subspace and a second subspace, the electric explosion valve 21 and the valve assembly 3 are arranged in the first subspace, the detection controller 4 is arranged in the second subspace, and the valve assembly 3 is arranged directly above the detection controller 4 along the second direction Z, so that the detection controller 4 is connected to the valve assembly 3 through a signal line, and the layout is more reasonable.

[0058] In other optional embodiments, when the electric explosion valve 21 is arranged outside the installation space S (not shown in the figure), the mounting member 1 is provided with a connecting port, which at least partially exposes the nozzle head 23, so that the nozzle head 23 can extend into the installation space S through the connecting port to atomize and spray the battery pack 30.

[0059] Optionally, the central area A2 may include a first area and a second area, the first area is flush with the edge area A1 along the first direction X, the second area is protruded relative to the first area and the edge area A1 along the first direction X and forms an installation area, and the electric explosion valve 21 is connected to the first area of ​​the mounting member 1.

[0060] Optionally, the nozzle head 23 may partially protrude from the connecting port along the first direction X, which is beneficial to improving the compactness of the structure, or may be entirely protruded from the connecting port, which is beneficial to ensuring the effectiveness of fire extinguishing of the fire-fighting device 10 .

[0061] Optionally, the opening area of ​​the communication port is larger than the outer diameter of the nozzle head 23 to ensure that the fire extinguishing medium can be smoothly ejected from the communication port. In addition, the shape of the communication port can be set to be circular, square, and of course, can also be set to other shapes, which is not limited in this application.

[0062] In some optional embodiments, the fire-fighting device 10 further includes a second seal 6 , which is disposed around an edge area A1 of the mounting member 1 , and the mounting member 1 is connected to the battery pack 30 via the second seal 6 .

[0063] By setting a second seal 6 in the edge area A1 of the mounting member 1, after the fire-fighting device 10 is installed in the battery pack 30, the fire-fighting nozzle 2 and the battery pack 30 can be sealed to prevent external substances such as water vapor and impurities from invading the installation space S and the battery pack 30, thereby achieving a higher level of protection, which is beneficial to improving the reliability of the fire-fighting device 10 and increasing the service life of the fire-fighting device 10.

[0064] Optionally, the second sealing member 6 can be configured as a sealing pad, which can be supported by rubber, or can be processed by other materials. In addition, the shape of the sealing pad can be set to a circular, square, etc., and of course, the sealing pad can also be the same shape as the edge area A1.

[0065] See also Figures 1 to 3 In some optional embodiments, the fire-fighting device 10 further includes a display module 7, which is disposed on the outer surface of the mounting member 1, connected to the detection controller 4 and configured to display the working status information of the fire-fighting device 10. By arranging the display module 7 on the outer surface of the mounting member 1, it is more convenient for the operation and maintenance personnel to intuitively judge the current working status of the fire-fighting device 10 and the battery pack 30, and realize on-site monitoring of the battery pack 30.

[0066] Optionally, the display module 7 may be disposed in the installation space S, and an observation window 14 may be disposed on the installation member 1 to expose the display module 7 through the observation window 14 for on-site observation by operation and maintenance personnel.

[0067] In some optional embodiments, the display module 7 includes a plurality of sound and light indicators, which are used to respectively display the operation information, alarm information and trigger information of the detection controller 4 .

[0068] As an optional implementation, the sound and light indicator can be set as an indicator light, and the multiple sound and light indicator parts include a green indicator light, a yellow indicator light and a red indicator light. The green indicator light is used to display the operation information of the detection controller 4, the yellow indicator light is used to display the alarm information of the detection controller 4, and the red indicator light is used to display the trigger information of the detection controller 4.

[0069] Specifically, when the detection controller 4 is powered on and operates normally, the green indicator light is on, otherwise the green indicator light is off.

[0070] When the detection controller 4 detects that the temperature inside the battery pack 30 reaches 70°C, or the content of smoke, combustible gas, organic volatiles, etc. reaches a certain value, the yellow indicator light is lit to warn the operation and maintenance personnel, otherwise the yellow indicator light is off.

[0071] When the detection controller 4 detects that the temperature inside the battery pack 30 reaches 100°C, or the content of smoke, combustible gas, organic volatiles, etc. reaches a threshold, that is, when the nozzle head 23 sprays the fire extinguishing medium into the battery pack 30, the red indicator light is on, otherwise the red indicator light is off.

[0072] By setting multiple indicator lights, when an alarm is triggered or a fire start signal is triggered according to the program setting, the working status of the fire-fighting device 10 can be intuitively displayed through the color and lighting status of different indicator lights, which is convenient for operation and maintenance personnel to observe on the spot. In addition, compared with the alarm sound, the use of indicator lights can make it easier for operation and maintenance personnel to quickly locate the abnormal battery pack 30 when multiple battery packs 30 and fire-fighting devices 10 are set, which is more convenient to use.

[0073] See also Figures 1 to 3 In some optional embodiments, the mounting member 1 is further provided with a second interface 13, and the detection controller 4 is configured to be connected to an external control system through the second interface 13. That is, the second interface 13 is an external communication interface, so that the relevant information of the detection controller 4 is uploaded to the external control system through the second interface 13 to realize remote monitoring and complete comprehensive judgment.

[0074] The fire-fighting device 10 in the embodiment of the present application integrates functional components for detecting various risk abnormal characteristics, controlling the spraying of fire-extinguishing media, and on-site monitoring and remote monitoring of the working status of the fire-fighting device 10. At the same time, the above-mentioned functional components can be installed in an integrated manner on the outside of the battery pack 30, which greatly simplifies the installation and maintenance work.
