Detailed Implementation

[0031] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0032] Example 1

[0033] Please see Figures 1-5The energy storage cabinet shown in the figure includes a cabinet body 101 with a hinged door. Inside the cabinet body 101 are four mounting brackets 102 arranged symmetrically in pairs. Multiple mounting plates 103 are arranged between the four mounting brackets 102. A power conversion module 104 is provided on the top mounting plate 103. Each of the other mounting plates 103 is provided with a battery 105. The cabinet body 101 also includes a protective component for supporting and protecting each battery 105 during installation and removal.

[0034] Specifically, the protective components include a sliding plate 201 slidably connected to the cabinet 101, a protective plate 202 hinged to the side of the sliding plate 201 away from the battery 105, a driving component for driving the protective plate 202 is provided inside the cabinet 101, and a limiting component for limiting the battery 105 is provided on the protective plate 202.

[0035] It should be noted that, through the design of the protective components, the battery 105 can be stably moved to a high mounting point or from a high mounting point to a low position, thus eliminating the need for maintenance personnel to lift the battery 105. This improves the convenience of installing and removing the battery 105 and reduces the risk of slippage due to the weight of the battery 105, thereby enhancing the safety of installing and removing the battery 105.

[0036] It is worth noting that the energy storage cabinet consists of battery modules, power conversion system, battery management system, heat dissipation system (which can be installed on the cabinet door or the bottom of the cabinet 101), and cabinet 101 and protection system. As existing technology, its specific structure and working principle have been mastered by those in the field, and will not be elaborated on here.

[0037] Please see Figures 3-5 The drive assembly shown in the figure includes a lead screw 301 and a drive rod 302 disposed between two opposing inner walls of the cabinet 101. Drive sleeves 303 are respectively adapted to be connected to the side walls of the lead screw 301 and the drive rod 302. One of the two drive sleeves 303 is slidably connected to the side wall of the drive rod 302, and the other of the two drive sleeves 303 is threadedly connected to the lead screw 301. The side of the two drive sleeves 303 that is close to each other is connected to the sliding plate 201. The two drive sleeves 303 are provided with a push assembly for pushing the protective plate 202. The drive assembly facilitates the movement of the protective plate 202 at different heights.

[0038] Please see Figure 2 The cabinet 101 in the figure is equipped with a drive motor 304 on the top, and the output end of the drive motor 304 is connected to the lead screw 301; the drive motor 304 facilitates the rotation of the lead screw 301.

[0039] Please see Figure 3 The push assembly shown in the figure includes a multi-stage electric push rod motor 401 hinged to the drive sleeve 303 near the protective plate 202. The output end of the multi-stage electric push rod motor 401 is provided with a push rod 402. The output end of the push rod 402 is hinged to the side of the protective plate 202 away from the drive motor 304. The push assembly facilitates the rotation of the protective plate 202, thereby enabling folding and storage, which reduces the space occupied by the protective plate 202 when not in use.

[0040] Working principle: During operation, when an external power source (such as the power grid, solar photovoltaic panels, wind turbines, etc.) is connected to the energy storage cabinet, the power conversion module 104 first rectifies the input AC power to convert it into DC power. Then, based on the battery 105 status information provided by the BMS, it adjusts the charging current and voltage to charge the battery 105 module using a suitable charging strategy. During the charging process, the BMS monitors the voltage, temperature, and other parameters of the battery 105 unit in real time to prevent overcharging.

[0041] When the energy storage cabinet receives a discharge command (such as a load demand or grid dispatch command), the battery 105 outputs DC power, and the power conversion module 104 converts it into AC power that meets the requirements and outputs it. The BMS controls the discharge current and voltage according to the SOC of the battery 105 and the load demand, etc., to ensure that the battery 105 discharges in a safe and stable state. During the discharge process, the parameters of the battery 105 cell are also monitored to prevent over-discharge.

[0042] During use, the energy storage cabinet coordinates the work of various parts such as the battery module 105, power conversion module 104, and BMS by utilizing the internal control system according to the preset energy management strategy and external instructions. It can realize a variety of functions according to different application scenarios and needs, such as peak shaving and valley filling, frequency regulation, and backup power supply.

[0043] When it is necessary to maintain the battery 105, first open the cabinet door, then start the drive motor 304 to drive the lead screw 301 to rotate. During the rotation of the lead screw 301, the sliding plate 201 is moved by the thread meshing transmission between the lead screw 301 and the drive sleeve 303 and the guiding action of the drive rod 302. When the sliding plate 201 is moved to be aligned with the mounting plate 103 of the battery 105 to be removed, stop the rotation of the drive motor 304.

[0044] Then, the multi-stage electric push rod motor 401 is started to push the protective plate 202 to rotate. When the protective plate 202 rotates to be flush with the sliding plate 201, the battery 105 placed on the mounting plate 103 can be slid onto the protective plate 202 with the assistance of the sliding plate 201. After the battery 105 slides onto the protective plate 202, the limiting component is used to limit the battery 105. Then, the driving component is used again to drive the battery 105 to move to a lower position, thereby realizing the disassembly of the battery 105 located at a high position and the lowering of the height after disassembly, so as to facilitate the maintenance personnel to pick up the battery 105 at a lower position.

[0045] When installing battery 105 after maintenance, the same principle is used, so that battery 105 is lifted by the protective plate 202 and moved to the high installation point by the cooperation of the drive component and the limiting component. This eliminates the need for maintenance personnel to lift battery 105, thereby improving the convenience of installing and removing battery 105. At the same time, it also reduces the risk of slipping due to the weight of battery 105, thereby improving the safety of installing and removing battery 105.

[0046] After the maintenance of battery 105 is completed, the protective plate 202 can be rotated by pushing the component, thereby folding and storing it, thus reducing the space occupied by the protective plate 202 when it is not in use.

[0047] Example 2

[0048] Please see Figure 4 This embodiment further illustrates Example 1. The limiting component shown in the figure includes two mutually symmetrically arranged limiting plates 501. The two limiting plates 501 are slidably connected to the side of the protective plate 202 that receives the battery 105. The two ends opposite to each other of the two limiting plates 501 are respectively fixedly connected to inclined guide plates 502. The protective plate 202 is provided with a moving component for moving the guide plates 502.

[0049] Please see Figures 3-5 The movable component shown in the figure includes two sets of symmetrically arranged movable holes 601 on the side wall of the protective plate 202. The two movable holes 601 located in the same horizontal row are respectively provided with guide rods 602 and double-ended threaded rods 603. Two guide plates 604 are slidably connected to the side wall of the guide rods 602. The two guide plates 604 are slidably connected to the movable holes 601 and connected to two limiting plates 501. Two movable plates 605 are threadedly connected to the side wall of the double-ended threaded rods 603. The two movable plates 605 are slidably connected to the other two of the four movable holes 601 and connected to the limiting plates 501. The movable component facilitates the movement of the two limiting plates 501 towards or away from each other, thereby facilitating the limiting or releasing of the battery 105.

[0050] Please see Figure 5 The protective plate 202 in the figure is equipped with a motor 606 on one side. The output end of the motor 606 is connected to the double-threaded rod 603. The motor 606 is used to drive the double-threaded rod 603 to rotate. The double-threaded rod 603 refers to a threaded rod with two threads in opposite directions on its side wall.

[0051] In this embodiment, by setting up a limiting component, when the battery 105 is placed on the protective plate 202, the rotation of the motor 606 drives the double-ended threaded rod 603 to rotate. During the rotation of the double-ended threaded rod 603, the threaded engagement between the double-ended threaded rod 603 and the moving plate 605, as well as the guiding effect of the guide rod 602 and the moving plate 605, drive the two limiting plates 501 to move closer to or further away from each other. This facilitates limiting or releasing the battery 105, thereby improving the positional stability of the battery 105 on the protective plate 202 and ensuring the safety of the battery 105 during movement at height.

[0052] Example 3

[0053] Please see Figure 4 This embodiment is a further description of other embodiments. The protective plate 202 in the figure is provided with an auxiliary component for reducing friction when the battery 105 slides. The auxiliary component includes two symmetrically arranged protective holes 701 opened on the side of the protective plate 202 near the battery 105. The two protective holes 701 are rotatably connected to a plurality of rotating rollers 702.

[0054] It should be noted that by setting up auxiliary components and utilizing the rotation of multiple rotating rollers 702, the sliding friction of the battery 105 on the protective plate 202 is reduced during installation and removal, thereby improving the safety of installing and removing the battery 105.

[0055] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
