Description

Technical Field

[0001] This application relates to the field of energy storage technology, and in particular to an energy storage cabinet and energy storage system. Background Technology

[0002] Currently, water-based fire suppression is the last line of defense for fire extinguishing of energy storage cabinets. Typically, pipes are connected from the outside of the cabinet to the top inside, spraying water downwards. However, the installation of these fire hoses occupies space on the sides and top and bottom of the cabinet, resulting in a larger cabinet size and increased costs. Furthermore, when shipping by sea, there are height restrictions; if the cabinet is too tall, it cannot fit into a standard shipping container, requiring a specially designed container and increasing transportation costs. Even if the multi-section spliced ​​(threaded and snap-fit) fire hoses are disassembled to fit the energy storage cabinet into a standard shipping container, the subsequent on-site reassembly is difficult (due to limited space inside the cabinet and significant dimensional errors after splicing).

They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0041] The following reference Figures 1 to 11 This application describes an energy storage cabinet and energy storage system according to some embodiments.

[0042] Example 1

[0043] See Figures 1 to 7 As shown, an embodiment of this application provides an energy storage cabinet, including: a cabinet body 1 and an energy storage component 2; wherein, the energy storage component 2 is installed inside the cabinet body 1; the cabinet body 1 includes a support beam 102, and one of the support beams 102 forms a conveying channel 1023 and a water inlet and a spraying section 1024 connected to the conveying channel 1023. The water inlet can be connected to an external fire-fighting liquid source through a pipe 8, and when the energy storage component 2 experiences thermal runaway, the external fire-fighting liquid can be conveyed to the spraying section 1024 through the conveying channel 1023, and the spraying section 1024 can spray fire-fighting liquid onto the energy storage component 2.

[0044] As can be seen from the structure described above, this application provides a novel energy storage cabinet that uses the support beam 102 as a fire water pipe, eliminating the need for a separate fire water pipe. This greatly saves space inside the cabinet 1, thereby helping to increase the space for the energy storage component 2 and reducing the material cost of the cabinet 1. It also does not require increasing the height of the cabinet 1, thus eliminating the need to redesign and manufacture freight containers, saving transportation costs. Moreover, compared to the fire water pipes in the prior art, it saves splicing steps, saving time and effort.

[0045] Further, preferably, such as Figure 1 and Figure 3 As shown, the cabinet 1 includes a support frame and multiple outer panels 103, with the outer panels 103 covering the outside of the support frame and connected to it. The aforementioned support beam 102 is part of the support frame. That is, the support frame includes the aforementioned support beam 102 and a rectangular main frame 101. The support beam 102 is fixed to the main frame 101, and a clearance notch is formed at the interference point between the main frame 101 and the support beam 102 to avoid the transverse support beam 1022 or the longitudinal support beam 1021. A through hole is provided on the outer panel 103 corresponding to the water inlet of the support beam 102 with the conveying channel 1023 to avoid the aforementioned pipe 8 connected to the fire-fighting liquid source.

[0046] It should be noted that the conveying channel 1023 is not limited to only one support beam 102; it can also be formed by more than one, such as two or three support beams 102, depending on the actual needs.

[0047] In this embodiment, preferably, as follows: Figure 5 and Figure 6As shown, the spraying section 1024 is a spray head, which sprays fire-fighting liquid onto the energy storage component 2 to increase the spraying area and spraying effect.

[0048] Furthermore, preferably, there are multiple spray heads, which are arranged sequentially at intervals along the length of the transverse support beam 1022 described below. Of course, this is not the only option; the multiple spray heads can be distributed arbitrarily, and the number of spray heads is not limited to multiple, but can also be one.

[0049] In this embodiment, preferably, as follows: Figure 2 and Figure 6 As shown, the support beam 102, which forms at least a conveying channel 1023 and a spraying part 1024, is a square tube; the spraying head has a first threaded connection part, the support beam 102 has a second threaded connection part, and the first threaded connection part and the second threaded connection part are threadedly connected.

[0050] As can be seen from the structure described above, if the support beam 102 forming the conveying channel 1023 and the spraying part 1024 adopts a circular tube structure, the conventional spray head cannot be directly assembled with the arc-shaped sidewall of the circular tube. It is necessary to design a special T-fitting. Specifically, a notch is cut out of the support beam 102, the T-fitting is installed at the notch, and the two ends of the T-fitting are connected to the openings of the corresponding support beams 102 on both sides. The third end of the T-fitting is threadedly connected to the spray head. The above structure is extremely complex, with many connection points, requiring multiple welding operations, which is time-consuming and labor-intensive, and the probability of leakage is high. In order to solve the above problems, this application designs the support beam 102 forming the conveying channel 1023 and the spraying part 1024 as a square tube structure. In this way, the spray head can be directly screwed onto the square tube, thereby eliminating the T-fitting, reducing the number of connection points, saving time and labor, and reducing the probability of leakage.

[0051] Furthermore, preferably, the outer wall of the end opening of the spray head is provided with external threads, i.e., the aforementioned first threaded connection portion, and the support beam 102 is formed with threaded holes, i.e., the aforementioned second threaded connection portion. This allows the end opening of the spray head to be directly screwed into the threaded hole, achieving a threaded connection between the spray head and the support beam 102. Of course, this is not limited to this; alternatively, the outer wall of the end opening of the spray head may be provided with internal threads, a connecting hole may be provided on the support beam 102, and a protruding mounting ring may be provided around the connecting hole. The outer wall of the mounting ring may be provided with external threads, and the end opening of the spray head may be screwed onto the mounting ring, etc.

[0052] In this embodiment, preferably, as follows: Figure 2As shown, the support beam 102 includes a transverse support beam 1022 and a longitudinal support beam 1021; wherein, along the height direction of the energy storage component 2, the transverse support beam 1022 is disposed on the top of the energy storage component 2; the longitudinal support beam 1021 is disposed on the side of the energy storage component 2; both the transverse support beam 1022 and the longitudinal support beam 1021 form a conveying channel 1023 and are connected to each other, and the fire-fighting liquid can be conveyed to the spraying unit 1024 in sequence through the conveying channel 1023 in the longitudinal support beam 1021 and the transverse support beam 1022.

[0053] As can be seen from the structure described above, the fire-fighting fluid entering from the outside is transported through the transport channel 1023 in the longitudinal support beam 1021 located on the side of the energy storage component 2 to the transport channel 1023 in the transverse support beam 1022 located at the top of the energy storage component 2, and finally transported to the top sprinkler head. The sprinkler head sprays the fire-fighting fluid downward toward the energy storage component 2, so that the fire-fighting fluid can flow along the entire height of the energy storage component 2, increasing the contact area with the energy storage component 2 and improving the fire extinguishing effect.

[0054] Furthermore, preferably, the transverse support beam 1022 is fixed to the top of the main frame 101, and the longitudinal support beam 1021 is fixed to the side of the main frame 101. An avoidance gap is formed at the interference point between the main frame 101 and the transverse support beam 1022 or the longitudinal support beam 1021, which serves to avoid the transverse support beam 1022 or the longitudinal support beam 1021.

[0055] Furthermore, preferably, the longitudinal support beam 1021 has a first opening on its side, and the transverse support beam 1022 has a second opening at one end near the longitudinal support beam 1021, with the first and second openings connected; one end of the longitudinal support beam 1021 is closed, and the other end has a third opening, with a stop welded to this third opening for sealing; one end of the longitudinal support beam 1021 is closed, and the other end has a fourth opening, with a stop welded to this fourth opening for sealing. Of course, it is not limited to the transverse support beam 1022 being directly molded into a hollow structure with one closed end and the other open; the longitudinal support beam 1021 can also be directly molded into a hollow structure with both ends closed and the side open.

[0056] Furthermore, preferably, the transverse support beam 1022 and the longitudinal support beam 1021 are sealed together by welding. Of course, this is not the only option.

[0057] Furthermore, preferably, the transverse support beam 1022 is connected to the main frame 101 by welding. Of course, it is not limited to this.

[0058] Furthermore, preferably, the longitudinal support beam 1021 is connected to the main frame 101 by welding. Of course, it is not limited to this.

[0059] It should be noted that the structure of the support beam 102 is not limited to the above. The support beam 102 may include only the longitudinal support beam 1021, that is, the vertical support beam 102, or only the transverse support beam 1022, that is, the longitudinal support beam 1021, or other structures may be adopted, depending on the actual needs.

[0060] In this embodiment, preferably, as follows: Figure 7 As shown, the energy storage component 2 includes an electrical box 22 and multiple battery packs 21, and the electrical box 22 and multiple battery packs 21 are stacked together along the height direction of the cabinet 1; the energy storage cabinet also includes lead-out pipes (not shown), the electrical box 22 and each battery pack 21 are equipped with lead-out pipes, and the interior of the electrical box 22 is connected to the cooling channel inside the support beam 102 through the corresponding lead-out pipes, and the interior of each battery pack 21 is connected to the cooling channel inside the support beam 102 through the corresponding lead-out pipes.

[0061] As can be seen from the structure described above, depending on different needs, the fire-fighting fluid in the support beam 102 can be introduced into the battery pack 21 at a designated location (such as the battery pack 21, electrical box 22, or other fire-prone areas) to achieve targeted spraying.

[0062] It should be noted that the structure is not limited to the above. It is also possible to equip only the electrical box 22 with lead-out pipes, or only the battery pack 21 with lead-out pipes. Furthermore, it is not only possible to equip each battery pack 21 with lead-out pipes, but also to equip only one battery pack 21 or only a portion of the battery packs 21 with lead-out pipes, etc., depending on the actual needs.

[0063] In this embodiment, preferably, as follows: Figure 2 , Figure 3 and Figure 7 As shown, the energy storage cabinet also includes a bracket assembly, which is located inside the cabinet 1 and connected to the support beam 102. Each battery pack 21 is equipped with a bracket assembly. Each bracket assembly includes a first bracket 3 and a second bracket 4, which are respectively located on both sides of the cabinet 1. The battery pack 21 is installed on the corresponding first bracket 3 and second bracket 4.

[0064] As can be seen from the structure described above, the first bracket 3 and the second bracket 4 serve to support the battery pack 21, making the battery pack 21 more stable.

[0065] In this embodiment, preferably, as follows: Figure 2As shown, the first bracket 3 is welded to the support beam 102, which is simple and convenient to operate. Especially when the first bracket 3 needs to be fixedly connected to the support beam 102 with the conveying channel 1023, the welding process, compared with the bolt fixing method, does not require drilling holes in the support beam 102, thus not damaging the conveying channel 1023, and therefore not causing leakage problems, making it safer and more reliable. Of course, it is not limited to this; a snap-fit ​​connection can also be used. It should also be noted that when the first bracket 3 is connected to the support beam 102 without the conveying channel 1023, a bolt connection can also be used.

[0066] In this embodiment, preferably, as follows: Figure 2 As shown, the second bracket 4 is welded to the support beam 102, which is simple and convenient to operate. Especially when the first bracket 3 needs to be fixedly connected to the support beam 102 with the conveying channel 1023, the welding process, compared with the bolt fixing method, does not require drilling holes in the support beam 102, thus not damaging the conveying channel 1023, and therefore not causing leakage problems, making it safer and more reliable. Of course, it is not limited to this; a snap-fit ​​connection can also be used. It should also be noted that when the second bracket 4 is connected to the support beam 102 without the conveying channel 1023, a bolt connection can also be used.

[0067] In this embodiment, preferably, as follows: Figure 3 As shown, the first bracket 3 includes a first support plate 31 and a first limiting plate 32 and a second limiting plate 33 connected to the first support plate 31; wherein, the first support plate 31 is L-shaped, and one side of the battery pack 21 sits on the first support plate 31, that is, the bottom of one side of the battery pack 21 sits on the horizontal part of the first support plate 31, and the vertical part of the first support plate 31 is located on one side of the battery pack 21.

[0068] Along the height direction of the first support plate 31, the first limiting plate 32 is set on the top of the first support plate 31, and the first limiting plate 32 abuts against one side of the battery pack 21 to play a limiting role, so that the support beam 102 and the side of the battery pack 21 form a certain clearance space, which facilitates installation and avoids interference, etc.

[0069] Along the length of the first support plate 31, the second limiting plate 33 is disposed at the tail end of the first support plate 31, and the second limiting plate 33 is connected to the first limiting plate 32. The second limiting plate 33 abuts against one side of the back of the battery pack 21 to prevent the battery pack 21 from sliding out of the main frame 101, making the structure more reliable.

[0070] In this embodiment, preferably, the second bracket 4 includes a second support plate and a third limiting plate and a fourth limiting plate connected to the second support plate; wherein, the second support plate is L-shaped, and the other side of the battery pack 21 rests on the second support plate, that is, the bottom of the other side of the battery rests on the horizontal part of the second support plate, and the vertical part of the second support plate is located on the other side of the battery pack 21; along the height direction of the second support plate, the third limiting plate is disposed on the top of the second support plate, and the third limiting plate abuts against the other side of the battery pack 21, so that the support beam 102 and the side of the battery pack 21 form a certain clearance space, which facilitates installation and avoids interference, etc.

[0071] Along the length of the second support plate, a fourth limiting plate is disposed at the tail end of the second support plate, and the fourth limiting plate is connected to the third limiting plate. The fourth limiting plate abuts against the other side of the back of the battery pack 21, preventing the battery pack 21 from sliding out of the main frame 101, thus making the structure more reliable. It should be noted that the second bracket 4 can refer to the structure of the first bracket 3 as follows: Figure 3 The explanation is as shown.

[0072] In this embodiment, preferably, the energy storage cabinet also includes a temperature sensor, a smoke sensor, and a controller (not shown in the figure); wherein the temperature sensor and the smoke sensor are both installed inside the cabinet 1; the pipeline 8 is equipped with an electric valve, and the electric valve, the temperature sensor, and the smoke sensor are all communicatively connected to the controller.

[0073] As described above, when the temperature sensor and smoke sensor detect smoke or high temperature, and the smoke concentration or temperature reaches the set threshold, the controller will control the electric valve 9 to open, allowing external fire-fighting fluid to enter the cabinet 1 for online spraying or flooding. It should be noted that this type of controller is quite common and will not be described in detail here.

[0074] Furthermore, it should be noted that when valve 9 mentioned below is a manual valve rather than an electric valve, the energy storage cabinet also includes a temperature sensor, a smoke sensor, an alarm, and a controller. The temperature sensor and smoke sensor are both located inside the cabinet 1, while the alarm is located outside the cabinet 1. The temperature sensor, smoke sensor, and alarm are all communicatively connected to the controller. Pipeline 8 is equipped with a manual valve. Therefore, when the temperature sensor and smoke sensor detect smoke or high temperature, and the smoke concentration or temperature reaches a set threshold, the controller will trigger the alarm. Upon hearing the alarm, the user will manually open valve 9, thereby introducing fire-fighting fluid into the energy storage cabinet.

[0075] In addition, it should be noted that the aforementioned temperature sensor, smoke sensor, and controller may not be required. Thermal runaway can be detected by human observation. The specific choice depends on the actual needs.

[0076] In this embodiment, preferably, as follows: Figure 1 As shown, the energy storage cabinet includes a water inlet connector 5, which is installed on the cabinet body 1. The water inlet end of the water inlet connector 5 is located outside the cabinet body 1, and the water outlet end of the water inlet connector 5 is located inside the cabinet body 1 and is connected to the water inlet of the conveying channel 1023.

[0077] As can be seen from the structure described above, the water inlet connector 5 is set nearby and directly connected to the conveying channel 1023 in the support beam 102. This saves on intermediate connecting pipes, reduces material costs, reduces installation steps, improves production efficiency, and reduces leakage points due to the reduction of pipes, making it safer and more reliable.

[0078] It should be noted that: Other structures are not limited to those described above; for example: Figure 8 As shown, the energy storage cabinet includes a water inlet connector 5 and a water inlet pipe 6. The water inlet connector 5 is installed on the cabinet body 1, and the water inlet end of the water inlet connector 5 is located outside the cabinet body 1 and is used to connect to the pipeline 8. The water outlet end of the water inlet connector 5 and the water inlet pipe 6 are both located inside the cabinet body 1, and the water inlet pipe 6 is connected to the water inlet of the conveying channel 1023 and the water inlet connector 5, respectively. It can be seen that by setting the water inlet pipe 6, water from different directions can be introduced into the conveying channel 1023 of the support beam 102. Based on this, the position of the water inlet connector 5 can be reasonably arranged, and the application range is wider.

[0079] Example 2

[0080] See Figure 9 and Figure 10 As shown, the energy storage cabinet in this embodiment is an improvement on the basis of embodiment one. The technical content disclosed in embodiment one will not be described again, and the content disclosed in embodiment one is also part of the content disclosed in this embodiment.

[0081] The energy storage cabinet provided in this embodiment differs in structure from the energy storage cabinet provided in Embodiment 1 in that: Figure 9 and Figure 10 As shown, the spraying part 1024 is a spraying hole formed on the support beam 102.

[0082] As can be seen from the structure described above, spray holes can be directly opened on the support beam 102, which can save spray heads and thus help reduce costs. Moreover, spray holes can be set on the entire transverse support beam 1022, making the spraying range wider and the spraying more uniform, so as to play a role in all-round cooling and fire extinguishing.

[0083] Example 3

[0084] See Figure 11As shown, Embodiment 3 of this application also provides an energy storage system, including the energy storage cabinet described in Embodiment 1 or Embodiment 2 above. Therefore, it has all the beneficial technical effects of the energy storage cabinet, and the same technical features and beneficial effects will not be repeated.

[0085] In this embodiment, preferably, as follows: Figure 10 As shown, the energy storage system also includes a fire-fighting liquid storage tank 7, a delivery pump, a pipeline 8, and a valve 9; wherein, one end of the pipeline 8 is connected to the fire-fighting liquid storage tank 7 through the delivery pump, and the other end of the pipeline 8 is connected to the water inlet, and further preferably, the other end of the pipeline 8 is connected to the aforementioned water inlet interface; the valve 9 is installed on the pipe fitting and is used to control the opening and closing of the pipeline 8, which makes it more controllable.

[0086] As can be seen from the structure described above, when the energy storage component 2 experiences thermal runaway, valve 9 is opened, and the delivery pump can deliver the fire-fighting liquid in the fire-fighting liquid storage tank 7 to the pipeline 8, and then from the pipeline 8 to the delivery channel 1023 of the longitudinal support beam 1021, and then to the delivery channel 1023 of the transverse support beam 1022, and finally to the spraying unit 1024, from which it is sprayed toward the energy storage component 2.

[0087] Furthermore, preferably, valve 9 is an electric valve 9. When the temperature sensor or smoke sensor detects smoke or high temperature, and the smoke concentration or temperature reaches a set threshold, the controller opens this electric valve 9, allowing external fire-fighting fluid to enter the cabinet 1 for online spraying or flooding. Of course, this is not limited to this; valve 9 can also be a manual valve 9, depending on actual needs.

[0088] Furthermore, preferably, the fire-fighting liquid storage tank 7 can store water, that is, the aforementioned fire-fighting liquid is water. Of course, it is not limited to this and can also be other types of fire-fighting liquid.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
