Description

Technical Field

[0001] The present invention belongs to the technical field of energy storage cabinets, and in particular relates to an energy storage cabinet capable of automatically adjusting a heat dissipation air duct. Background Art

[0002] In the context of the current energy structure transformation and the rapid development of renewable energy, energy storage technology is becoming increasingly important as a key link in balancing the supply and demand of the power grid and improving the flexibility of the power system. As one of the core devices for realizing the storage and release of electric energy, energy storage cabinets are widely used in power systems, distributed energy, electric vehicle charging stations and other fields, and play an irreplaceable role in promoting efficient energy utilization and enhancing the stability of the power grid.

[0003] However, there are some limitations in the design of energy storage cabinets in the prior art, especially in terms of the fixed structure and heat dissipation management of the battery rack. These problems directly restrict the overall efficiency and economy of the energy storage system. Specifically, the battery racks in existing energy storage cabinets are often designed to be fixed, which means that the layout and capacity adjustment of the battery pack lack flexibility. With the continuous advancement of battery technology and the changes in application scenario requirements, this non-adjustable battery rack design limits the adaptability of the energy storage system to batteries of different specifications, affecting the system's upgrade and expansion potential and maintenance convenience.

[0004] In addition, in order to control the temperature rise in the energy storage room, the existing solutions tend to rely on enhanced active heat dissipation measures, such as increasing the power of the cooling fan to increase the air circulation, so as to achieve the purpose of cooling. Although this approach can alleviate the negative impact of high temperature to a certain extent, it hides a significant disadvantage behind it - a significant increase in energy consumption. When the high-power cooling fan is running, it not only directly consumes additional electricity, but also may aggravate the noise pollution problem, which runs counter to the development concept of energy conservation, emission reduction, and green environmental protection. At the same time, over-reliance on active heat dissipation and neglecting the optimization design of thermal management inside the energy storage cabinet is not conducive to the overall efficiency and sustainable operation of the system in the long run.

[0005] In summary, the shortcomings of existing energy storage cabinet technology in terms of battery rack adjustability and heat dissipation management efficiency urgently need to be overcome through innovative design and technological innovation to achieve more flexible, efficient, energy-saving and environmentally friendly energy storage solutions.

[0035] Reference Figures 1 to 8, an energy storage cabinet capable of automatically adjusting a heat dissipation duct, wherein an energy storage chamber 100 and a control chamber 200 are arranged inside the energy storage chamber 100, a battery rack 300 is installed in the energy storage chamber 100, and a plurality of battery cavities 310 for installing battery boxes 500 are arranged on the battery rack 300, and a control module 210 is installed in the control chamber 200, and the battery rack 300 includes a first frame body 320, a second frame body 330 and a driving assembly, and the first frame body 320 and the second frame body 330 are connected by a plurality of control assemblies 400.

[0036] The first frame 320 and the second frame 330 each include a plurality of cross-shaped assembly units 340, and the assembly units 340 are distributed in a rectangular array. The assembly units 340 are provided with a plurality of tube arms 341, and the assembly units 340 are connected by telescopic shafts 342, and the two ends of the telescopic shafts 342 are respectively assembled in the tube arms 341 of two adjacent groups of assembly units 340. The battery chamber 310 is located in the space surrounded by the tube arms 341 of adjacent assembly units 340. The control assembly 400 is assembled and connected with the assembly unit 340. The control assembly 400 includes a connecting shaft 410, a plurality of limiting shafts 420 and a plurality of limiting supporting members 430. The connecting shaft 410 is provided with a plurality of gear parts 411. The limiting supporting member 430 includes a rack part 431 and a supporting part 432. The rack part 431 is meshed with the gear part 411. The supporting part 432 extends into the corner of the battery cavity 310. The battery box 500 is fixed and limited by the limiting supporting members 430 located at the four corners of the battery cavity 310. The limiting shaft 420 is against the back of the rack part 431. One end of the connecting shaft 410 extends from the rear of the second frame 330 and is connected to the driving assembly. The control module 210 is electrically connected to the driving assembly.

[0037] The dynamic adjustment working principle of the battery rack is based on mechanical transmission and telescopic mechanism to adjust the spacing between battery boxes. The specific working principle is as follows: when no adjustment is performed, each assembly monomer 340 is connected by the telescopic shaft 342, and the limit support member 430 is in a relatively fixed position. At this time, the battery box 500 is stably supported and fixed in the battery cavity 310. When adjusting, the connecting shaft is rotated. As the connecting shaft rotates, the limit support member 430 extends toward the battery cavity 310. Due to the existence of the battery box 500, the distance between the limit support members 430 remains unchanged, and the assembly monomer 340 is required to adapt to this change. Therefore, the spacing between adjacent assembly monomers 340 increases, and the telescopic shaft 342 is exposed, thereby increasing the spacing between the battery boxes 500.

[0038] Through the above design, the present application can dynamically adjust the air duct spacing between the battery boxes 500 according to the real-time monitored ambient temperature changes. Specifically, when the external ambient temperature rises, the battery rack 300 automatically increases the air duct spacing between the battery boxes 500, which can increase the air circulation, accelerate the heat dissipation, and prevent the battery from overheating and causing performance degradation or shortened life. On the contrary, in a cold environment, the system will reduce the air duct spacing and reduce the circulation of cold air to avoid the battery temperature being too low, affecting its charging and discharging efficiency and maintaining the stable working state of the battery. And the above heat dissipation adaptive adjustment design can be combined with an intelligent algorithm, through the study and analysis of historical data, predict the temperature trend in the future period of time, pre-adjust the air duct settings, and further improve the reaction speed and adjustment accuracy. Such a design not only reduces unnecessary energy consumption and extends the service life of the entire energy storage system, but also significantly improves energy utilization efficiency and reduces operating costs, which is of great significance for promoting the development of green energy storage technology.

[0039] In order to ensure the smoothness of the folding and unfolding of the battery rack 300, the upper and lower ends of the battery rack 300 are equipped with a first slide rail 110, and the battery rack 300 is slidably assembled with the first slide rail 110. Second slide rails 120 are provided on both sides of the energy storage chamber 100, and the two ends of the first slide rail 110 are slidably assembled with the second slide rail 120. The first slide rail 110 and the second slide rail 120 cooperate to form a stable and smooth multi-point sliding support system, which not only ensures the stability of the battery rack 300 during the folding and unfolding process, but also effectively disperses the stress during the sliding process, prevents local wear, and prolongs the service life of the system. The number of limit support members 430 on the same connecting shaft 410 extending into the same battery cavity 310 is at least 2 groups. This design can increase the stability of the battery rack 300 to the battery box 500 and ensure the stability of the battery box 500 during the folding and unfolding process of the battery rack 300.

[0040] As an embodiment of the present application, the driving assembly includes a driving device and a sub-transmission module, the number of the sub-transmission modules is equal to the number of battery cavities 310, and the driving device is connected to one of the sub-transmission modules. The sub-transmission module includes a pulley 440, a transmission belt 441 and a tensioning module. There are four groups of pulleys 440 and they are respectively mounted on the connecting shafts 410 located at the four corners of the battery cavity 310, and the transmission belt 441 is connected and transmitted with the four groups of pulleys 440. The tensioning module is connected to the transmission belt 441 to ensure the tension of the transmission belt 441. The four groups of pulleys 440 located on the same connecting shaft 410 are arranged in one piece. Through the above design, the battery rack 300 only needs one driving device as a power source to synchronously drive the sub-transmission modules of all battery cavities 310 to complete the retraction and expansion of the battery rack 300. This design simplifies the design complexity of the control system, reduces energy consumption, and at the same time improves the synchronization and response speed of the retraction and expansion of the battery rack 300.

[0041] The tensioning module includes a plurality of torque members 450, and the plurality of torque members 450 are evenly distributed and assembled on the tube arms 341 on the four sides of the battery chamber 310. The torque member 450 includes a torque shaft 451 and a tensioning shaft 452, and the torque shaft 451 and the tensioning shaft 452 are connected by a connecting plate 453. The torque shaft 451 is assembled and connected to the tube arm 341, and the torque member 450 has one end of the tensioning shaft 452 set free, and the transmission belt 441 is wound around the tensioning shaft 452. When the battery rack 300 is unfolded, the torque member 450 is rotated by force, so that the transmission belt 441 between the pulleys 440 can stretch to adapt to the gradually increasing spacing between the pulleys 440. This design ensures the continuity of transmission, and at the same time can ensure the tension control during the transmission process, reduce the wear and slippage of the transmission belt 441, thereby extending the service life of the system and reducing the failure rate.

[0042] As another embodiment of the present application, the driving assembly includes a plurality of driving motors (not shown in the drawings), the number of which is equal to the number of the control assembly 400 and is assembled one by one. Compared with the previous embodiment which can only control the whole, the present embodiment can realize the individual drive of a column or a row of assembled cells 340, and can implement specific heat dissipation management for a battery box 500 in a specific area, which can effectively avoid the safety hazards caused by local overheating, extend the battery life, balance the temperature distribution in each area, reduce the performance degradation and safety risks caused by uneven temperature, and maintain the stability and efficiency of the entire battery system.

[0043] In addition, in the present application, the battery box 500 is provided with a locking switch 510 and a plurality of telescopic locking members 520, and the locking switch 510 is electrically connected to the plurality of telescopic locking members 520 to uniformly control the telescopic locking members 520. The limiting support member 430 is provided with a locking groove 433, and the telescopic locking member 520 includes a locking tongue. When the battery box 500 is locked, the locking switch 510 controls the locking tongue to extend into the locking groove 433 to achieve position locking of the battery box 500. A limiting sheet metal member 530 is provided at the side of the front side of the battery box 500. After the position locking of the battery box 500 is completed, the limiting sheet metal member 530 is against the first frame 320. The setting of the limiting sheet metal member 530 can prevent the battery box 500 from being pushed in too deep and causing the locking tongue and the locking groove 433 to be misaligned.

[0044] Specifically, the design utilizes the electrical connection between the locking switch 510 and the telescopic locking member 520 to achieve unified control of the battery box 500 fixing process. The operator only needs to simply operate the locking switch 510 to drive the locking tongue to extend into the locking groove 433 on the limit support member 430 to complete the position locking of the battery box 500 without the need for traditional tool assistance and cumbersome threaded connection steps. This design not only simplifies the installation process of the battery box 500 and reduces the requirements for professional skills, but also greatly shortens the time required for maintenance and replacement of the battery box 500, and improves the response speed and flexibility of the overall system.

[0045] The protection scope of the present invention includes but is not limited to the above embodiments. The protection scope of the present invention shall be based on the claims. Any replacement, deformation, and improvement of the technology that can be easily thought of by technicians in this field shall fall within the protection scope of the present invention.
