Description

Technical Field

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

[0002] With the rapid development of the new energy industry, the penetration rate of renewable energy sources such as wind and solar power is constantly increasing. As a core device for balancing energy supply and demand and ensuring the stable operation of the power grid, energy storage equipment is being used in increasingly wider scenarios. As an integrated energy storage unit, the energy storage cabinet integrates core components such as battery packs and electronic control systems into one unit. It has advantages such as small footprint, flexible deployment, and convenient operation and maintenance, and is one of the core devices of the energy storage system.

[0003] Because energy storage cabinets need to achieve higher energy storage capacity within a limited space, the internal components of the energy storage cabinet have high integration requirements. At the same time, the safety performance and ease of operation and maintenance of the energy storage cabinet are also closely related to the integrated design of the energy storage cabinet. A reasonable integrated layout can simplify cable connection, optimize heat dissipation efficiency, and reduce the difficulty of troubleshooting.

[0004] Existing energy storage cabinets, despite their highly integrated design, still suffer from numerous shortcomings that fail to meet practical application needs: First, the internal installation structure of existing energy storage cabinets often employs a single bracket or a decentralized installation method, lacking overall planning for battery pack installation positions. This results in low utilization of internal space, hindering high-density battery pack integration and making installation and disassembly cumbersome, which is detrimental to later operation and maintenance. Second, the layout of auxiliary components and battery pack units within existing energy storage cabinets lacks coordinated design, often being scattered across different areas of the cabinet. This not only occupies extra space but also leads to messy cable routing, increasing the risk of line interference and reducing the overall structural compactness, further restricting the integration level and ease of use of the energy storage cabinet. Third, existing energy storage cabinets neglect the functional compatibility between components, failing to quickly and comprehensively monitor and respond to internal safety hazards, resulting in low operational reliability.

[0005] Therefore, there is an urgent need to design a highly integrated and compactly laid-out energy storage cabinet to solve the technical problem that existing energy storage cabinets are difficult to integrate. Utility Model Content

[0006] To overcome the shortcomings of existing technologies, this application provides an energy storage cabinet, specifically adopting the following technical solution:

[0007] An energy storage cabinet includes a cabinet structure, a battery pack unit, and an electronic control mechanism.

[0008] The cabinet structure includes a cabinet shell, mounting brackets, and door units. The mounting brackets are located inside the cabinet shell and have multiple mounting positions along the height direction. The door units are located on the front and / or rear walls of the cabinet shell.

[0009] The mounting bracket consists of two bracket units arranged opposite each other on both sides of the cabinet housing. Each bracket unit includes a longitudinal mounting bracket and a transverse mounting bracket. The longitudinal mounting bracket is a support frame with a semi-open or closed rectangular cross-section. Multiple longitudinal mounting brackets are arranged side by side at intervals. The longitudinal mounting brackets are fixed relative to the side wall of the cabinet housing, and the longitudinal mounting bracket at the frontmost part of the cabinet housing has multiple bolt holes for fixing the battery pack. Each bracket unit has multiple transverse mounting brackets distributed horizontally at intervals along the height direction. The transverse mounting brackets are support frames with an L-shaped cross-section and are fixedly connected to the longitudinal mounting brackets located in the same bracket unit. The transverse mounting brackets at the same height in the two bracket units form a mounting position.

[0010] The battery pack unit includes multiple battery packs connected in series and / or in parallel, which are distributed sequentially in the mounting position; the electrical control mechanism is located at the bottom or side wall of the cabinet housing.

[0012] Optional: The energy storage cabinet may also include a fire suppression system located on the top or side wall of the cabinet housing.

[0013] Furthermore: the fire protection system includes a fire data acquisition unit and a fire execution unit. The fire data acquisition unit is located on the top or side wall of the cabinet housing, and the fire execution unit is located on the top of the cabinet housing.

[0014] Furthermore: the fire data acquisition mechanism employs one or more of a temperature sensor, a combustible gas sensor, or a smoke alarm; the fire actuator includes one or more of a fire sprinkler head, a high-pressure gas cylinder, or an aerosol-type fire extinguishing device.

[0015] Optional: The cabinet housing has multiple cable mounting ports on the side.

[0016] Optionally: The door unit includes a first door unit and / or a second door unit. The first door unit is located on the front wall of the cabinet housing; the second door unit is located on the rear wall of the cabinet housing. The first door unit and / or the second door unit are provided with door limiters, which are provided with strip-shaped limit grooves. A limit link is provided between the cabinet housing and the door limiters. One end of the limit link is hinged to the cabinet housing, and the other end of the limit link is provided with a sliding engagement part that engages with the strip-shaped limit groove. The limit link limits the maximum opening and closing angle of the door unit relative to the cabinet housing.

[0017] Optionally: the first door unit is provided with a first air conditioning mechanism for circulating refrigerant inside the cabinet housing; and / or the second door unit is provided with a second air conditioning mechanism for circulating refrigerant inside the cabinet housing.

[0018] Optional: The energy storage cabinet is equipped with a lighting mechanism, which includes a lighting body and a limit switch. The lighting body is located on the top of the cabinet housing, and the limit switch is located on the cabinet housing near the door unit. The opening and closing action of the door unit controls the limit switch to perform the switching action, thereby controlling the lighting body to turn on or off.

[0019] Optional: The door unit is equipped with a door lock mechanism, which includes a lock body, a first extension rod, a second extension rod, and a locking element. The lock body is installed on the door unit. The first extension rod is arranged above the lock body, with one end connected to the lock body and the other end connected to a locking element. The second extension rod is arranged below the lock body, with one end connected to the lock body and the other end also connected to a locking element. When the door unit is closed relative to the cabinet housing, the lock body drives the first and second extension rods to move in opposite directions, causing the locking element to extend into the cabinet housing near the rear side of the limiting flange of the door unit, thereby locking the door unit.

[0020] Optional: The door lock mechanism also includes a limiting member arranged on the cabinet housing. The first extension rod and the second extension rod correspond to at least one limiting member, and the first extension rod and the second extension rod are provided with limiting grooves that cooperate with the limiting member. When the first extension rod and the second extension rod are displaced in opposite directions, the limiting member engages with the limiting groove to lock the door unit.

[0021] The technical solution of this application achieves the following beneficial effects:

[0022] This application's energy storage cabinet optimizes the mounting bracket design of the cabinet structure, employing two opposing bracket units combined with a longitudinal mounting bracket and an L-shaped transverse mounting bracket. Multiple standardized mounting positions are planned along the height direction inside the cabinet shell, achieving a layered and dense arrangement of battery pack units. This design significantly improves the utilization rate of the cabinet's internal space, allowing for the integration of more battery packs and significantly increasing the energy storage capacity per unit volume, fully meeting the core requirements of high integration. Furthermore, the bolt holes on the longitudinal mounting brackets enable rapid positioning and fixing of the battery packs, making the integration and assembly of the battery packs and mounting brackets more convenient and reducing the difficulty of integration and assembly. Simultaneously, this internal layout effectively compresses the space occupied by components, reduces cable length and clutter, and lowers the risk of wiring interference. Moreover, the rigid connection design between each mechanism and the cabinet structure makes the overall structure of the energy storage cabinet more compact and stable, achieving a high degree of integration and unification of functional components and the cabinet, and improving the structural reliability of the energy storage cabinet during transportation, installation, and operation.

[0044] Example 1:

[0045] Combination Figure 1-12 As shown, Embodiment 1 discloses an energy storage cabinet, which includes a cabinet structure, a battery pack unit, and an electronic control mechanism. (Refer to...) Figure 1 , Figure 2 and Figure 11 As shown, the cabinet mechanism includes a cabinet housing 1, a mounting bracket 3, and a door unit 2. The mounting bracket 3 is located inside the cabinet housing 1 and has multiple mounting positions along the height direction, which can realize the layered and orderly installation of the battery pack 4. The door unit 2 is arranged on at least one side of the front wall 1a or the rear wall 1b of the cabinet housing to facilitate the inspection and maintenance of the internal components.

[0046] In this embodiment 1, the mounting bracket 3 uses two bracket units arranged opposite to each other on both sides of the cabinet housing 1 to form a symmetrical support structure, thereby improving the stable support for the battery pack 4.

[0047] Specifically, refer to 8 and Figure 12As shown, each bracket unit includes a longitudinal mounting frame 301 and a transverse mounting frame 302. The longitudinal mounting frame 301 can be a support frame with a semi-open cross section or a closed rectangular cross section. The longitudinal mounting frame 301 is preferably formed by bending metal sheet multiple times to improve the support strength of the longitudinal mounting frame 301.

[0048] In this embodiment 1, two or more longitudinal mounting brackets 301 are provided, and these longitudinal mounting brackets 301 are arranged side by side with intervals. When the battery pack 4 is installed in place on the mounting bracket 3 of the energy storage cabinet, there is a longitudinal mounting bracket 301 at the front and rear of the side surface of the battery pack 4 as end supports; the remaining longitudinal mounting brackets 301 are distributed between the two longitudinal mounting brackets 301 that serve as end supports, and serve as intermediate supports. The number of longitudinal mounting brackets 301 can be adjusted according to the volume of the energy storage cabinet, its own cross-sectional area, etc. For example, if the front-to-back dimension of the energy storage cabinet is long, the number of longitudinal mounting brackets 301 can be appropriately increased, or if its own cross-sectional area is small, the number of longitudinal mounting brackets 301 can also be appropriately increased to improve the support strength. It should be noted that in this embodiment 1, the longitudinal mounting bracket 301 is fixed relative to the side wall 1c of the cabinet housing. The fixing method can be a direct connection, such as by welding or bolts, to the side wall 1c of the cabinet housing. Alternatively, the longitudinal mounting bracket 301 and the side wall 1c of the cabinet housing can be fixedly connected by connecting short rods 303 respectively. The fixing method can be selected according to the heat exchange requirements of the internal cavity of the energy storage cabinet.

[0049] Refer to 8 and Figure 12 As shown in Embodiment 1, each bracket unit has multiple horizontal mounting frames 302 spaced horizontally along its height. These horizontal mounting frames 302 are L-shaped cross-section supports. The horizontal mounting frames 302 are fixedly connected to the vertical mounting frames 301 located on the same bracket unit. For example, the horizontal mounting frames 302 can be fixed to the vertical mounting frames 301 by welding or bolting to ensure the stability of the connection. Mounting positions are formed between the horizontal mounting frames 302 at the same height in two bracket units. The battery pack unit includes multiple battery packs 4 connected in series or parallel. These battery packs 4 can be sequentially distributed within the mounting positions, achieving a layered and dense arrangement of the battery pack units. This significantly improves the utilization rate of the internal space of the cabinet, allowing for the integration of more battery packs 4 and significantly increasing the energy storage capacity per unit volume of the energy storage cabinet, fully meeting the core requirement of high integration.

[0050] Reference Figure 8 As shown, in this embodiment 1, a plurality of bolt holes 3011 for fixing the battery pack 4 are provided on the longitudinal mounting bracket 301 located at the front end of the cabinet housing 1. Combined with... Figure 2As shown, when the battery pack 4 is located on the mounting bracket 3, the bolt holes 3011 can be matched with the corresponding holes on the battery pack 4, and bolts can be used to tighten them, thereby achieving rapid positioning and fixing of the battery pack 4. This makes the integration and assembly of the battery pack 4 and the mounting bracket 3 more convenient, reduces the difficulty of integration and assembly, and further prevents the battery pack 4 from shaking during transportation or handling of the energy storage cabinet. As a preferred method, the bolt holes 3011 on the longitudinal mounting bracket 301 can be equipped with corresponding nuts. These nuts can be fixed to the longitudinal mounting bracket 301 by welding, snap-fitting, riveting, etc. Thus, when installing the battery pack 4, it is only necessary to pass the bolts through the corresponding holes on the battery pack 4 and the longitudinal mounting bracket 301, and then tighten them with the nuts. There is no need to carry extra nuts, further improving installation efficiency.

[0051] Furthermore, in this embodiment 1, the electrical control mechanism is located at the bottom 1e of the cabinet housing or on the side wall 1c of the cabinet housing. This electrical control mechanism can be flexibly configured according to actual needs, as shown in the following figure. Figure 2 Figure 11 As shown, when the electrical control mechanism includes a high-voltage box 5, the high-voltage box 5 can be arranged at the bottom 1e of the cabinet housing, below the battery pack unit. This layout can make full use of the space at the bottom of the cabinet, while facilitating the wiring connection between the high-voltage box 5 and the battery pack unit, reducing cable length and the risk of wiring interference. (Refer to...) Figure 2 Figure 11 As shown, when the electrical control mechanism includes a distribution box 6, the distribution box 6 can be installed at the bottom 1e or the side wall 1c of the cabinet housing. The distribution box 6 provides a line interface to external loads to meet the power supply needs of the energy storage cabinet to external devices. Its location can be determined based on the convenience of connecting external loads and the rationality of the overall internal layout of the cabinet. In practical applications, the electrical control mechanism can also integrate more control modules and protection devices according to the specific functional requirements of the energy storage cabinet to achieve precise control, status monitoring, and safety protection of the battery pack units, ensuring that the energy storage cabinet can operate stably and reliably under various operating conditions.

[0052] In this embodiment 1, a fire-fighting mechanism is installed inside the energy storage cabinet. This mechanism is located on the top 1d of the cabinet housing or on the side wall 1c of the cabinet housing. As an important component of the energy storage cabinet's safety protection, this fire-fighting mechanism can meet the needs of fire prevention and emergency response. It should be noted that in this embodiment 1, the fire-fighting device is preferably located in the cavity space between the front surface of the battery pack 4 and the front wall 1a of the cabinet housing for easy maintenance and replacement.

[0053] Specifically, refer to Figure 2 , Figure 4 , Figure 6 as well as Figure 11As shown, the fire protection system includes a fire data acquisition unit and a fire execution unit, which work together to provide fire safety measures for the energy storage cabinet. In this embodiment 1, the fire data acquisition unit is located on the top 1d or side wall 1c of the cabinet shell. Its specific location is chosen to facilitate real-time monitoring of fire-related parameters such as temperature, combustible gas concentration, and smoke inside the energy storage cabinet. The fire data acquisition unit can be one or more of a temperature sensor, a combustible gas sensor 701, or a smoke alarm 704. Through the fire data acquisition unit, abnormal signals can be captured in a timely manner in the event of thermal runaway or the early stage of a fire in the energy storage cabinet, and the signals are transmitted to the fire execution unit. The fire execution unit is located on the top 1d of the cabinet shell and includes one or more of a fire sprinkler head 706, a high-pressure gas cylinder, or an aerosol fire extinguishing device 705. The specific type can be selected according to the potential safety hazards of the energy storage cabinet and its surrounding environment. When the fire monitoring agency detects an abnormality inside the energy storage cabinet, it will immediately trigger the fire control mechanism to take action. For example, the fire sprinkler 706 will spray extinguishing agent, the high-pressure gas tank will release high-pressure extinguishing gas to extinguish the fire, and the aerosol extinguishing device 705 will release aerosol to extinguish the fire, thereby controlling the spread of the fire in a timely manner.

[0054] As a preferred embodiment, refer to Figure 2 As shown, in this embodiment 1, multiple cable mounting ports 101 are provided on the side wall 1c of the cabinet housing. These cable mounting ports 101 are used to organize and secure cables between the energy storage cabinet and external equipment, ensuring neat and orderly cable arrangement and reducing mutual interference and wear between cables. It should be noted that the size and number of these cable mounting ports 101 can be adjusted according to the specifications and quantity of cables between the energy storage cabinet and external equipment to meet the needs of different application scenarios. Simultaneously, auxiliary structures such as cable clamps or protective grooves can be configured at these cable mounting ports 101 to further enhance the cable fixing and sealing effects, improving the neatness and safety of the internal layout of the energy storage cabinet.

[0055] In a preferred embodiment, the door unit 2 in this embodiment 1 includes at least one of a first door unit or a second door unit. For example, the first door unit can be located on the front wall 1a of the cabinet housing as a front door, and the second door unit can be located on the rear wall 1b of the cabinet housing as a rear door, to facilitate inspection and maintenance of different areas inside the cabinet. Figure 2As shown, when the main components of the energy storage cabinet are arranged in the cavity space between the front surface of the battery pack 4 and the front wall 1a of the cabinet housing, the door unit 2 of the energy storage cabinet can use only the first door unit as the front door, so that the operator can open and close the first door unit to inspect the front of the energy storage cabinet. Alternatively, when the main components inside the energy storage cabinet are distributed in both the front and rear of the cabinet, the door unit 2 of the energy storage cabinet can use the first door unit as the front door and the second door unit as the rear door, so that the operator can open and close the first door unit or the second door unit according to the inspection needs, so as to inspect the front or rear of the energy storage cabinet.

[0056] As a preferred embodiment, in order to maintain a stable internal temperature, the energy storage cabinet in Embodiment 1 requires an air conditioning mechanism 8 to be installed on its surface. This air conditioning mechanism 8 can be arranged in either the first door unit or the second door unit. (Refer to...) Figure 9 As shown, for example, when the energy storage cabinet only has a first door unit, that is, only a front door, the air conditioning mechanism 8 can be arranged on the first door unit; when the energy storage cabinet has a first door unit and a second door unit, that is, both a front door and a rear door, the air conditioning mechanism 8 is preferably arranged on the second door unit, but it can also be arranged on the first door unit. The location can be selected according to the actual layout requirements of the energy storage cabinet. Specifically, the air conditioning mechanism 8 includes an outdoor air conditioning unit and an indoor air conditioning unit. The outdoor air conditioning unit is usually installed in a suitable area outside the energy storage cabinet to facilitate heat exchange and ventilation; the indoor air conditioning unit is installed inside the energy storage cabinet to regulate the temperature inside the cabinet through cooling or heating. When the temperature inside the energy storage cabinet is too high, the air conditioning mechanism 8 starts the cooling mode to cool the air inside the cabinet and lower the temperature; when the temperature is too low, it starts the heating mode to heat the air inside the cabinet and raise the temperature inside the cabinet, thereby ensuring that the energy storage cabinet operates stably in a suitable temperature environment and extending the service life of key components such as the battery pack 4.

[0057] As a preferred embodiment, combined with Figure 3 and Figure 9As shown in Embodiment 1, when the energy storage cabinet is equipped with at least one of a first door unit or a second door unit, a door limiter 201 can be configured in the corresponding door unit 2. This door limiter 201 is used to limit the opening angle of the door to prevent excessive swinging and collisions during opening. It also prevents accidental closure due to external influences when the door is open, such as in windy weather, to avoid door shaking and injury to operators. Specifically, the door limiter 201 can be fixed to the lower part of the corresponding door unit 2 by bolts or welding, and the door limiter 201 has a strip-shaped limiting groove 2011. Meanwhile, a limiting link 202 is provided between the cabinet housing 1 and the door limiter 201. One end of the limiting link 202 is hinged to the link engagement part 104 at the bottom 1e position of the cabinet housing, and the other end of the limiting link 202 is provided with a sliding engagement part 2021. The sliding engagement part 2021 is slidably engaged with the strip-shaped limiting groove 2011. When the door unit 2 opens and closes, the sliding engagement part 2021 slides relative to the strip-shaped limiting groove 2011. When the sliding engagement part 2021 moves to the near end position 201a of the strip-shaped limiting groove, the door unit 2 reaches the maximum opening and closing angle relative to the cabinet housing 1.

[0058] It should be noted that in this embodiment 1, both the first door unit and the second door unit are connected to the corresponding wall surface of the cabinet housing 1 via hinges, enabling flexible opening and closing. The cabinet housing 1 can be equipped with a limiting flange 103 at the closed position of the door unit 2, such as... Figure 5 As shown, the limiting flange 103 is adapted to the outline of the door unit 2, and a sealing strip is provided on the limiting flange 103 or the door unit 2. The sealing strip and the limiting flange 103 can effectively prevent external dust, moisture and other substances from entering the cabinet and protect important internal components from damage.

[0059] As a preferred embodiment, combined with Figure 9As shown, in this embodiment 1, a door lock mechanism 9 is configured on the door unit 2. The door lock mechanism 9 includes a lock body 901, a first extension rod 902, a second extension rod 903, and a locking member 904. The lock body 901 is installed on the door unit 2. The first extension rod 902 is arranged above the lock body 901, and one end of the first extension rod 902 is connected to the lock body 901, while the other end of the first extension rod 902 is connected to a locking member 904. The second extension rod 903 is arranged below the lock body 901, and one end of the second extension rod 903 is connected to the lock body 901, while the other end of the second extension rod 903 is also connected to a locking member 904. When the door unit 2 is closed relative to the cabinet housing 1, the lock body 901 drives the first extension rod 902 and the second extension rod 903 to move in opposite directions, causing the locking member 904 to extend into the cabinet housing 1 near the rear side of the limiting flange 103 of the door unit 2, thereby locking the door unit 2. The door lock mechanism 9, driven by the lock body 901, enables the synchronous displacement of the first extension rod 902 and the second extension rod 903, thereby driving the locking member 904 to extend or retract. For example... Figure 10 As shown, the locking mechanism, in which the locking element 904 extends into the rear side of the limiting flange 103 of the cabinet housing 1, increases the stability of the door closure.

[0060] Example 2:

[0061] Combination Figure 1-10 As shown in the figure, this embodiment 2 specifically discloses an energy storage cabinet, which includes a cabinet structure, a battery pack unit, and an electronic control mechanism. The cabinet structure includes a cabinet shell 1, a mounting bracket 3, and a door unit 2, wherein the door unit 2 is configured with only a first door unit.

[0062] Combination Figure 2 and Figure 8 As shown, in this embodiment 2, the mounting bracket 3 adopts two bracket units arranged opposite to each other on both sides of the cabinet housing 1. Each bracket unit includes a longitudinal mounting bracket 301 and a transverse mounting bracket 302. The longitudinal mounting bracket 301 adopts a support frame with a closed rectangular cross section. The longitudinal mounting bracket 301 is preferably formed by bending metal sheet multiple times to improve the support strength of the longitudinal mounting bracket 301.

[0063] Furthermore, in combination Figure 2 and Figure 8 As shown, in this embodiment 2, each bracket unit has two longitudinal mounting brackets 301, which are arranged side by side with intervals. When the battery pack 4 is installed on the mounting bracket 3 of the energy storage cabinet, the front and rear sides of the side surface of the battery pack 4 are each supported by a longitudinal mounting bracket 301 as end supports. The longitudinal mounting bracket 301 is directly fixed to the side wall 1c of the cabinet housing by welding. Of course, other fixing methods can also be used to fix the longitudinal mounting bracket 301 to the side wall 1c of the cabinet housing.

[0064] like Figure 8 As shown in Embodiment 2, each bracket unit has multiple horizontal mounting frames 302 distributed at horizontal intervals along the height direction. Each horizontal mounting frame 302 is an L-shaped cross-section support frame, and the horizontal mounting frames 302 are bolted to the longitudinal mounting frames 301 located on the same bracket unit. Furthermore, in Embodiment 2, each horizontal mounting frame 302 has a positioning hook at its end. This positioning hook can engage with the slot of the longitudinal mounting frame 301. The positioning hook and slot cooperation allows for positioning of the horizontal mounting frame 302 during assembly, and also provides partial support for the battery pack 4 arranged on the mounting bracket 3.

[0065] In this embodiment 2, the horizontal mounting brackets 302 at the same height in the two bracket units form an installation position. The battery pack unit includes multiple battery packs 4 connected in series or in parallel. The battery packs 4 can be distributed in the installation position in sequence, realizing the layered and dense arrangement of the battery pack units, which greatly improves the utilization rate of the internal space of the cabinet, and can integrate more battery packs 4, significantly improving the energy storage capacity per unit volume of the energy storage cabinet, and fully meeting the core requirement of high integration.

[0066] In addition, such as Figure 8 As shown in Embodiment 2, a plurality of bolt holes 3011 for fixing the battery pack 4 are provided on the longitudinal mounting bracket 301 located at the front end of the cabinet housing 1. Each bolt hole 3011 is provided with a corresponding nut, such as a riveting nut.

By passing the bolts through the battery pack 4 and the corresponding holes on the longitudinal mounting bracket 301, and tightening them with the nuts, the battery pack 4 can be quickly positioned and fixed.

[0067] As a preferred embodiment, combined with Figure 2 As shown, in this embodiment 2, the electrical control mechanism includes a high-voltage box 5 and a distribution box 6. The high-voltage box 5 is located at the bottom 1e of the cabinet housing and below the battery pack unit. This arrangement makes full use of the space at the bottom of the cabinet and facilitates the wiring connection between the high-voltage box 5 and the battery pack unit, reducing cable length and interference. The distribution box 6 is located on the side wall 1c of the cabinet housing. The distribution box 6 can be used with the cable mounting port 101 located on the side wall 1c of the cabinet housing. Cables of external devices can be pre-fixed through the cable mounting port 101, and then the cable connection ports can be connected to the corresponding terminal blocks inside the distribution box 6 to achieve a stable connection between the external devices and the energy storage cabinet. Simultaneously, the cable mounting port 101 can be used to organize and fix the cables between the energy storage cabinet and external devices, ensuring neat and orderly cable arrangement and reducing mutual interference and wear between cables.

[0068] In this embodiment 2, a fire-fighting mechanism is configured inside the energy storage cabinet. The fire-fighting mechanism is arranged on the top 1d of the cabinet shell or the side wall 1c of the cabinet shell.

[0069] Specifically, this fire protection agency includes fire data collection and fire enforcement agencies. (Combined) Figures 4-6 As shown, in this embodiment 2, the fire detection mechanism includes a combustible gas sensor 701 and a smoke detector 704. The smoke detector 704 is located on the top 1d of the cabinet housing, while the combustible gas sensor 701 is located on the side wall 1c of the cabinet housing, near the distribution box 6. Furthermore, a temperature sensor can be added to this fire detection mechanism, which can be located on the top 1d of the cabinet housing. This fire detection mechanism can promptly detect abnormal temperature or gas signals in the event of thermal runaway or the initial stage of a fire in the energy storage cabinet, and transmit the signals to the fire-fighting actuator. The fire-fighting actuator includes fire sprinklers 706 and a high-pressure gas cylinder or aerosol-type fire extinguishing device 705. Two fire sprinklers 706 are provided, located on the top 1d of the cabinet housing, and connected to external fire-fighting fluid via pipelines. Once a fire signal is received inside the energy storage cabinet, the fire sprinklers 706 will spray fire-fighting fluid to extinguish the fire. The high-pressure gas cylinder and the aerosol fire extinguishing device 705 can be selected to be arranged on the top 1d or side wall of the cabinet shell. When thermal runaway occurs inside the energy storage cabinet, the high-pressure gas cylinder or the aerosol fire extinguishing device 705 can be used to release a large amount of fire extinguishing gas or aerosol to extinguish the fire and control the spread of the fire in time.

[0070] In addition, such as Figure 2 As shown in this embodiment 2, in order to prevent the internal pressure from increasing suddenly and being unable to be released when thermal runaway occurs in the energy storage cabinet, a pressure relief hole is also provided on the side wall of the cabinet shell 1. The pressure relief hole can be used to quickly remove the high-pressure gas inside, so as to avoid dangerous situations such as explosion of the energy storage box due to excessive pressure and ensure the safe operation of the energy storage cabinet.

[0071] In a preferred embodiment, the front wall 1a of the cabinet housing in this embodiment 2 is provided with a first door unit, and correspondingly, an air conditioning mechanism 8 is provided on the first door unit. Figure 9 As shown, by utilizing the cooling and heating modes of the air conditioning unit 8, the internal temperature of the cabinet is kept stable, enabling the energy storage cabinet to operate stably in a suitable temperature environment and extending the service life of key components such as the battery pack 4.

[0072] Furthermore, refer to Figure 9As shown, in this embodiment 2, a door limiter 201 is configured in the first door unit. The door limiter 201 is fixed to the lower part of the corresponding first door unit by bolts. The door limiter 201 is provided with a strip-shaped limiting groove 2011. At the same time, a limiting link 202 is provided between the cabinet housing 1 and the door limiter 201. In this embodiment 2, the limiting link 202 is a long strip-shaped metal plate. One end of the limiting link 202 is hinged to the link engagement part at the bottom 1e position of the cabinet housing. The other end of the limiting link 202 is provided with a sliding engagement part 2021. The sliding engagement part 2021 slides with the strip-shaped limiting groove 2011. When the door unit 2 opens and closes, the sliding engagement part 2021 slides relative to the strip-shaped limiting groove 2011. When the sliding engagement part 2021 moves to the near end position 201a of the strip-shaped limiting groove, the first door unit reaches the maximum opening and closing angle relative to the cabinet housing 1.

[0073] like Figure 5 As shown, in this embodiment 2, the cabinet housing 1 is provided with a limiting flange 103 at the closed position of the first door unit. The limiting flange 103 is arranged to fit the outline of the first door unit, and the first door unit is provided with a sealing strip. The sealing strip and the limiting flange 103 can effectively prevent external dust, moisture and other substances from entering the cabinet and protect important internal components from damage.

[0074] As a preferred embodiment, such as Figure 9 As shown, in this embodiment 2, a door lock mechanism 9 is configured on the first door unit. The door lock mechanism 9 includes a lock body 901, a first extension rod 902, a second extension rod 903, and a locking member 904. The lock body 901 is installed at the middle of one side of the first door unit. The first extension rod 902 is arranged above the lock body 901, with one end connected to the lock body 901 and the other end connected to a locking member 904. The second extension rod 903 is arranged below the lock body 901, with one end connected to the lock body 901 and the other end also connected to a locking member 904. When the first door unit is closed relative to the cabinet housing 1, the lock body 901 drives the first extension rod 902 and the second extension rod 903 to move in opposite directions, causing the locking member 904 to extend into the cabinet housing 1 near the rear side of the limiting flange 103 of the first door unit, thereby locking the first door unit. The door lock mechanism 9, driven by the lock body 901, achieves synchronous displacement of the first extension rod 902 and the second extension rod 903, thereby causing the locking member 904 to extend or retract. Figure 10 As shown, the locking mechanism, in which the locking element 904 extends into the rear side of the limiting flange 103 of the cabinet housing 1, increases the stability of the door closure.

[0075] As a preferred embodiment, combined with Figure 8 , Figure 9 and Figure 13 As shown, in this embodiment 2, the door lock mechanism 9 also includes a limiting member 906 arranged on the cabinet housing 1. At least one limiting member 906 corresponds to each of the first extension rod 902 and the second extension rod 903. The limiting member 906 has two hook-shaped portions 9061. Correspondingly, the first extension rod 902 and the second extension rod 903 each have two limiting grooves 905 that engage with the hook-shaped portions 9061 of the limiting member 906. When the first extension rod 902 and the second extension rod 903 move in opposite directions, the hook-shaped portions 9061 of the limiting member 906 will engage with the limiting grooves 905, thereby locking the first door unit through the limiting member 906 and the limiting grooves 905. Of course, when it is necessary to unlock the first door unit, the first extension rod 902 and the second extension rod 903 can be moved synchronously towards the lock body 901. At this time, the hook-shaped portions 9061 of the limiting member 906 will disengage from the corresponding limiting grooves 905 of the extension rods.

[0076] As a preferred embodiment, combined with Figure 6 and Figure 7 As shown in the figure, this embodiment 2 also includes a lighting mechanism inside the energy storage cabinet. This lighting mechanism includes a lamp body and a limit switch. The lamp body is located on the top 1d of the cabinet housing, while the limit switch is located on the cabinet housing 1 near the first door unit. When the first door unit is closed, the limit switch is pressed back by the first door unit and is in the closed state, at which point the lamp body is off, consuming no power. However, when an operator opens the first door unit to perform maintenance or other operations inside the energy storage cabinet, the pressure on the limit switch from the first door unit disappears, causing the limit switch to extend and open, thereby controlling the lamp body to turn on. This provides sufficient light for the operator to clearly view the internal components of the energy storage cabinet, improving the efficiency and accuracy of maintenance and other operations.

[0083] As a preferred embodiment, combined with Figure 11As shown, in this embodiment 3, the electrical control mechanism includes a high-voltage box 5 and a distribution box 6. The high-voltage box 5 is located at the bottom 1e of the cabinet housing and below the battery pack unit. This arrangement makes full use of the space at the bottom of the cabinet and facilitates the wiring connection between the high-voltage box 5 and the battery pack unit, reducing cable length and wiring interference. The distribution box 6 is also located at the bottom 1e of the cabinet housing and below the high-voltage box 5. Both sides of the distribution box 6 are directly opposite the cable mounting ports 101 on the side wall 1c of the cabinet housing. The cable mounting ports 101 can be referenced from those in embodiment 2. Figure 2 The arrangement is as follows: external equipment cables can be pre-fixed through cable mounting ports 101, and then the cable connection ports directly enter the distribution box 6 and are connected to the corresponding terminal blocks inside the distribution box 6 to achieve a stable connection between the external equipment and the energy storage cabinet. At the same time, the cable mounting ports 101 can be used to organize and fix the cables between the energy storage cabinet and the external equipment, that is, to ensure that the cables are arranged neatly and orderly, and to reduce mutual interference and wear between the cables.

A temperature sensor can also be added to the fire detection mechanism, also positioned on the top 1d of the cabinet housing. This fire detection mechanism can promptly detect abnormal temperature or gas signals in the event of thermal runaway or the initial stage of a fire in the energy storage cabinet and transmit these signals to the fire control mechanism. The fire control mechanism includes an aerosol extinguishing device 705, positioned on the top 1d of the cabinet housing. When thermal runaway occurs inside the energy storage cabinet, the aerosol extinguishing device 705 can instantly release a large amount of extinguishing gas or aerosol to extinguish the fire and control its spread.

[0085] In a preferred embodiment, in this embodiment 3, a first door unit is provided on the front wall 1a of the cabinet housing, and a second door unit is provided on the rear wall 1b of the cabinet housing. An air conditioning mechanism 8 is provided on the second door unit, and the arrangement of the air conditioning mechanism can be referred to that in embodiment 2. Figure 9 The arrangement can be adjusted according to the actual condition of the energy storage cabinet. The cooling and heating modes of the air conditioning unit 8 ensure a stable internal temperature, allowing the energy storage cabinet to operate stably in a suitable temperature environment and extending the service life of key components such as the battery pack 4.

[0086] Furthermore, in this embodiment 3, door limiters 201 are configured in the first door unit and the second door unit, and their arrangement is the same as in embodiment 2. Figure 9 As shown, the door limiter 201 is fixed to the lower part of the corresponding door unit 2 by welding or bolting. The door limiter 201 is provided with a strip-shaped limiting groove 2011. At the same time, a limiting link 202 is provided between the cabinet housing 1 and the door limiter 201. Unlike embodiment 2, in this embodiment 3, the limiting link 202 is a metal rod with both ends bent into a hook shape. One end of the limiting link 202 is hinged to the bottom 1e position of the cabinet housing, and the other end of the limiting link 202 is provided with a sliding engagement part 2021. The sliding engagement part 2021 slides with the strip-shaped limiting groove 2011. When the door unit 2 opens and closes, the sliding engagement part 2021 slides relative to the strip-shaped limiting groove 2011. When the sliding engagement part 2021 moves to the near end position 201a of the strip-shaped limiting groove, the door unit 2 reaches the maximum opening and closing angle relative to the cabinet housing 1.

[0087] Similarly, in this embodiment 3, the cabinet housing 1 is provided with a limiting flange 103 at the closed position of the corresponding door unit 2, as can be seen in embodiment 2.

The lock body 901 is installed at the middle of one side of the corresponding door unit 2. The first extension rod 902 is arranged above the lock body 901, with one end connected to the lock body 901 and the other end connected to a locking member 904. The second extension rod 903 is arranged below the lock body 901, with one end connected to the lock body 901 and the other end also connected to a locking member 904. When the corresponding door unit 2 is closed relative to the cabinet housing 1, the lock body 901 drives the first extension rod 902 and the second extension rod 903 to move in opposite directions, causing the locking member 904 to extend into the cabinet housing 1 near the rear side of the limiting flange 103 of the corresponding door unit 2, thereby locking the door unit 2. The door lock mechanism 9 can achieve synchronous displacement of the first extension rod 902 and the second extension rod 903 by driving the lock body 901, thereby driving the locking member 904 to extend or retract. Furthermore, by using the locking member 904 to extend into the rear side of the limiting flange 103 of the cabinet housing 1, the stability of the door closure is increased.

[0089] Combination Figure 11 As shown, in addition, this embodiment 3 is provided with a display panel 10 on the mounting bracket biased towards the top 1d of the cabinet housing. The display panel 10 can display the operating data of the energy storage cabinet in real time so that the operator can keep abreast of the working status of the energy storage cabinet, including but not limited to key information such as the power, temperature and charging / discharging status of the battery pack 4.
