However, it will be apparent to those skilled in the art that the present disclosure embodiments may be implemented without one or more of these details. In other examples, certain technical features known in the art are not described to avoid confusion with the present disclosure embodiments.

[0030] The preferred embodiments of the present disclosure are described below with reference to the accompanying drawings. It should be noted that the terms "upper", "lower" and similar expressions used herein are for illustrative purposes only and are not intended to be limiting.

[0031] Herein, ordinal numbers such as “first” and “second” cited in the present disclosure are merely identifications and do not have any other meanings, such as a specific order or the like.

[0032] To thoroughly understand the embodiments of the present disclosure, detailed structures will be provided in the following description. It should be understood that the implementation of the embodiments of the present disclosure is not limited to the specific details familiar to those skilled in the art. Preferred embodiments of the present disclosure are described in detail below, but in addition to these detailed descriptions, the present disclosure may also have other embodiments.

[0033] The present disclosure provides an energy storage cabinet 1. The energy storage cabinet 1 can be used to house electronic components. The electronic components can include battery packs and / or electronic components. The electronic components can be disposed within an interior region 116 of a frame 110 of the energy storage cabinet 1. When a fire occurs in the electronic components, the frame 110 can spray a fire extinguishing medium (gaseous or liquid fire extinguishing material, such as carbon dioxide) toward the electronic components in a multi-directional manner to extinguish the fire.

[0034] As shown in Figure 1, the energy storage cabinet 1 includes a frame 110. The frame 110 is a substantially rectangular parallelepiped structure and is used to fix electronic components.

[0035] Frame 110 includes at least two (e.g., four) fire protection sections 190. Fire protection sections 190 include side beams 120. The side beams 120 of at least two fire protection sections 190 enclose an interior region 116 of frame 110. Electronic components are disposed within interior region 116 of frame 110. Side beams 120 have a first interior passage 122 and first through-holes 121. There are multiple first through-holes 121. First through-holes 121 communicate with first interior passages 122. First through-holes 121 face interior region 116 of frame 110.

[0036] It can be understood that in an embodiment not shown, there can also be only one fire fighting unit 190 .

[0037] Specifically, the side beam 120 includes a column beam 130 and an end beam 140. There are four column beams 130. The column beams 130 are located at the connection between any two sides of the rectangular structure formed by the frame 110. Along the length direction of the column beam 130, the end beam 140 is located at the end of the column beam 130. The length direction of the end beam 140 is perpendicular to the length direction of the column beam 130. The end of the end beam 140 is connected to the end of the column beam 130. The first internal channel 122 of the column beam 130 is connected to the first internal channel 122 of the end beam 140. The column beam 130 and the end beam 140 are both provided with a first through hole 121. In this way, the end beam 140 and the column beam 130 form a roughly rectangular structure. As a result, the strength of the frame 110 is great.

[0038] Firefighting section 190 also includes a reinforcement beam 150. Reinforcement beam 150 has a second internal passage 156 and a second through-hole 155. Multiple second through-holes 155 are provided. Second through-holes 155 communicate with second internal passage 156. The length of reinforcement beam 150 is inclined relative to the length of at least one side beam 120. For example, the length of reinforcement beam 150 is inclined relative to the length of end beam 140. The length of reinforcement beam 150 is perpendicular to the length of column beam 130. This simplifies the structure of frame 110.

[0039] The first end of the reinforcement beam 150 is connected to the side beam 120. Specifically, the first end of the reinforcement beam 150 is connected to one end of the column beam 130. The first end of the reinforcement beam 150 is also connected to one end of the end beam 140. In other words, the first end of the reinforcement beam 150 is connected to a corner of the frame 110. A corner of the frame 110 is the junction of any three faces of the rectangular parallelepiped structure formed by the frame 110. In this case, the second internal channel 156 of the reinforcement beam 150 connects the first internal channel 122 of the end beam 140 and the first internal channel 122 of the column beam 130. The second through hole 155 faces the interior of the interior area 116. The axial direction of the second through hole 155 forms an angle with the axial direction of the first through hole 121 of the column beam 130. Thus, the reinforcement beam 150 can increase the strength of the frame 110. In addition, the fire extinguishing medium can be sprayed onto the electronic components through the second through hole 155 of the reinforcement beam 150, further improving the efficiency of fire extinguishing.

[0040] In each fire protection section 190 , the second internal passage 156 of the reinforcement beam 150 and the first internal passage 122 of the side beam 120 are in communication with each other to form an internal passage of the fire protection section 190 .

[0041] At least two firefighting units 190 are each provided with a corresponding connection hole 111. Connection holes 111 communicate with the internal passages of the corresponding firefighting unit 190. The at least two connection holes 111 are each used to connect to a different external pipe 170. This allows multiple firefighting units 190 to simultaneously spray fire extinguishing medium onto electronic components within interior area 116 of frame 110.

[0042] It is understood that in an embodiment not shown, at least two connecting holes 111 are connected to the same external pipeline. The external pipeline is provided with a plurality of control valves for opening or closing the pipelines communicating with the respective connecting holes 111.

[0043] The internal passages of any two of the at least two fire fighting units 190 are isolated. In this way, different fire fighting units 190 can be controlled through different external pipes 170 to spray the fire extinguishing medium toward the electronic components, thereby spraying the fire extinguishing medium only at the fire location, reducing the consumption of the fire extinguishing medium.

[0044] In this embodiment, the frame 110 includes a firefighting unit 190, which comprises side beams 120 and reinforcement beams 150. At least two firefighting units 190 are each provided with a corresponding connection hole 111 for connecting to an external pipe 170. This allows different firefighting units 190 to be controlled to spray fire extinguishing medium onto the electronic components, thereby confining the fire location to the fire and reducing fire extinguishing medium consumption. Furthermore, each firefighting unit 190 can simultaneously spray fire extinguishing medium via both the side beams 120 and reinforcement beams 150, achieving rapid fire extinguishing. The provision of reinforcement beams 150 further enhances the strength of the frame 110.

[0045] Preferably, the reinforcement beam 150 includes a first end reinforcement beam 151 and a second end reinforcement beam 152. Along the length of the column beam 130, the first end reinforcement beam 151 is connected to one end of the column beam 130, and the second end reinforcement beam 152 is connected to the other end of the column beam 130. Thus, the fire extinguishing medium can be sprayed onto the electronic components simultaneously through the first end reinforcement beam 151 and the second end reinforcement beam 152.

[0046] Each of the first and second end reinforcement beams 151, 152 includes a first reinforcement beam 153 and a second reinforcement beam 154. The length of the first reinforcement beam 153 forms an angle with the length of the second reinforcement beam 154. The first end of the first reinforcement beam 153 is connected to one corner of the frame 110. The first end of the second reinforcement beam 154 is connected to the other corner of the frame 110. The first reinforcement beam 153 is connected to the second reinforcement beam 154. This further increases the strength of the frame 110.

[0047] Further optionally, each of the first-end reinforcement beam 151 and the second-end reinforcement beam 152 includes two first reinforcement beams 153 and two second reinforcement beams 154. The side beam 120 includes four column beams 130. For each of the first-end reinforcement beam 151 and the second-end reinforcement beam 152, the two first reinforcement beams 153 are coaxially arranged, with the first ends of the two first reinforcement beams 153 respectively connected to one end of the two column beams 130. The two second reinforcement beams 154 are coaxially arranged, with the first ends of the two second reinforcement beams 154 respectively connected to one end of the other two column beams 130. The second ends of the two second reinforcement beams 154 are connected to the second ends of the two first reinforcement beams 153, thereby further increasing the strength of the frame 110.

[0048] End beams 140 include a first end beam 141 and a second end beam 142. Along the length of column beam 130, first end beam 141 is connected to one end of column beam 130, while second end beam 142 is connected to the other end of column beam 130. This enhances the strength of frame 110. Furthermore, fire extinguishing media can be simultaneously sprayed onto electronic components via first and second end beams 141, 142.

[0049] Both first end beam 141 and second end beam 142 include a first end beam 143 and a second end beam 144. The length of first end beam 143 is perpendicular to the length of second end beam 144. First end beam 143 and second end beam 144 are connected at a corner, so that first internal channel 122 of first end beam 143 communicates with first internal channel 122 of second end beam 144. This allows fire extinguishing medium to be sprayed onto electronic components simultaneously through first end beam 143 and second end beam 144.

[0050] Preferably, the reinforcement beams 150 of two adjacent fire fighting parts 190 are connected. Thus, the structure of the frame 110 is simple.

[0051] Preferably, the reinforcement beams 150 of the two opposing fire fighting parts 190 are coaxially arranged. Thus, the structure of the frame 110 is simple.

[0052] Specifically, please continue to refer to Figure 1. There are four fire departments 190. The four fire departments 190 include a first fire department 112, a second fire department 113, a third fire department 114, and a fourth fire department 115. The first fire department 112, the second fire department 113, the third fire department 114, and the fourth fire department 115 are circumferentially spaced around the axis of the frame 110 (shown by the dotted line in Figure 1). The axis of the frame 110 is parallel to the length direction of the column beam 130. The axis of the frame 110 extends through the center of the first end reinforcement beam 151. Along the length direction of the first reinforcement beam 153, the center of the first end reinforcement beam 151 is the connection point between the first reinforcement beam 153 and the second reinforcement beam 154 of the first end reinforcement beam 151.

[0053] The length directions of the end beams 140 of any two fire fighting parts 190 are parallel or perpendicular.

[0054] Specifically, the first fire fighting section 112 includes a first column beam 130 , a first reinforcing beam 153 of the first end reinforcing beam 151 , a first reinforcing beam 153 of the second end reinforcing beam 152 , a second end beam 144 of the first end beam 141 , and a second end beam 144 of the second end beam 142 .

[0055] The second fire fighting section 113 includes a second column beam 130 , a second reinforcing beam 154 of the first end reinforcing beam 151 , a second reinforcing beam 154 of the second end reinforcing beam 152 , a first end beam 143 of the first end beam 141 , and a first end beam 143 of the second end beam 142 .

[0056] The third fire fighting section 114 includes a third column beam 130 , another first reinforcing beam 153 of the first end reinforcing beam 151 , another first reinforcing beam 153 of the second end reinforcing beam 152 , another second end beam 144 of the first end beam 141 , and another second end beam 144 of the second end beam 142 .

[0057] The fourth fire fighting section 115 includes a fourth column beam 130 , another second reinforcing beam 154 of the first end reinforcing beam 151 , another second reinforcing beam 154 of the second end reinforcing beam 152 , another first end beam 143 of the first end beam 141 , and another first end beam 143 of the second end beam 142 .

[0058] The internal passages of each fire-fighting section 190 are disconnected from the connections of the other fire-fighting sections 190. Specifically, a closing plate (not shown) is welded to the internal passages at the connection between the two fire-fighting sections 190 to seal the internal passages of the fire-fighting sections 190. For example, in the first-end reinforcement beam 151, the second ends of the first reinforcement beam 153 and the second ends of the second reinforcement beam 154 are both provided with closing plates to seal the second internal passage 156.

[0059] Continuing with Figure 1 , connection hole 111 is located at the end of column beam 130 . This position of connection hole 111 at a corner of frame 110 facilitates machining of connection hole 111 . Consequently, the fire extinguishing medium introduced into connection hole 111 via external conduit 170 can flow to column beam 130 , end beam 140 , and reinforcement beam 150 , and then be sprayed through column beam 130 , end beam 140 , and reinforcement beam 150 into interior area 116 , enabling more rapid fire extinguishing.

[0060] Preferably, reinforcing beams 150 are provided at both ends of column beam 130. The inner diameters of the reinforcing beams 150 at both ends of column beam 130 are identical. In other words, the inner diameter of the first-end reinforcing beam 151 is identical to the inner diameter of the second-end reinforcing beam 152. This allows the first-end reinforcing beam 151 and the second-end reinforcing beam 152 to be identical, facilitating fabrication of frame 110.

[0061] Preferably, the inner diameter of the column beam 130 is larger than the inner diameter of the end beam 140. Thus, fire can be extinguished more effectively.

[0062] Preferably, the inner diameter of the column beam 130 is larger than the inner diameter of the reinforcing beam 150. Thus, fire can be extinguished more effectively.

[0063] Preferably, end beams 140 are provided at both ends of the column beam 130. The inner diameters of the end beams 140 at both ends of the column beam 130 are the same along the length of the column beam 130. Thus, the end beams 140 at both ends of the column beam 130 can be made of the same type, facilitating the processing of the frame 110.

[0064] Preferably, the inner diameter of the reinforcing beam 150 is substantially the same as the inner diameter of the end beam 140. Thus, the end beam 140 and the reinforcing beam 150 can be made of the same type of beam, which facilitates the processing of the frame 110.

[0065] Preferably, the inner diameter of the second end beam 142 is substantially the same as the inner diameter of the first end beam 141. Thus, fire can be extinguished more effectively.

[0066] As shown in FIG1 , the energy storage cabinet 1 further includes a connector 160 . The connector 160 is connected to the edge of the connection hole 111 formed by the reinforcement beam 150 . The external pipe 170 is connected to the connection hole 111 via the connector 160 . This facilitates the installation of the external pipe 170 .

[0067] As shown in Figure 1, the energy storage cabinet 1 preferably further includes a sealing plate (not shown) which is connected to the frame 110 to form a cabinet structure.

[0068] The present disclosure further provides an energy storage system 2, as shown in FIG2 . The energy storage system 2 includes a plurality of batteries 200 and the aforementioned energy storage cabinet 1. Referring to FIG1 and FIG2 , the batteries 200 are disposed within the interior region 116 of the frame 110 .

[0069] The energy storage system 2 also includes at least two (for example, four) control valves 180. There is a one-to-one correspondence between the at least two control valves 180 and the at least two connection holes 111. The control valve 180 is used to connect to the corresponding connection hole 111, so as to open or close the pipeline connected to the corresponding connection hole 111. Specifically, the control valve 180 is arranged at the pipeline connected to the connection hole 111 corresponding to the control valve 180, so as to control the on-off of the pipeline. In other words, the control valve 180 is connected to the corresponding connection hole 111 through the pipeline, thereby facilitating the control of the delivery of the fire extinguishing medium to the connection hole 111, or cutting off the delivery of the fire extinguishing medium.

[0070] In this embodiment, the energy storage system 2 includes the aforementioned energy storage cabinet 1. The frame 110 includes a firefighting unit 190, which includes side beams 120 and reinforcement beams 150. At least two firefighting units 190 are each provided with a corresponding connection hole 111 for connecting to an external pipe 170. This allows different firefighting units 190 to be controlled to spray a fire-extinguishing medium onto the electronic components, thereby spraying the fire-extinguishing medium only at the location of the fire, reducing firefighting medium consumption. Furthermore, each firefighting unit 190 can simultaneously spray the fire-extinguishing medium via the side beams 120 and reinforcement beams 150, achieving rapid fire extinguishing. The provision of reinforcement beams 150 can further increase the strength of the frame 110.
