Description

Technical Field

[0001] The present invention relates to the technical field of energy storage cabinets, and specifically to a universal multi-scenario industrial and commercial energy storage cabinet system structure. Background Art

[0002] An energy storage cabinet is an integrated, modular energy storage device that centrally installs key components such as battery packs, battery management systems, power conversion systems, monitoring and protection devices, temperature control systems, and electrical connection components in a closed or semi-enclosed metal cabinet structure. It stores, releases, and manages electrical energy through unified control and coordination. It features standardized design, rapid deployment, and flexible expansion. It can operate efficiently in scenarios such as grid peak and frequency regulation, renewable energy grid integration and absorption, peak shaving and valley filling for industrial and commercial users, backup power supply, and microgrid energy management, thereby improving energy utilization efficiency, enhancing power system stability, and promoting the widespread use of clean energy.

[0003] The main frame of industrial and commercial energy storage cabinets mostly adopts a welded structure. However, a large number of welding operations can easily cause deformation of the main structure. This deformation problem will directly lead to difficulties in the subsequent battery pack assembly process. In addition, during the transportation of finished industrial and commercial cabinets, due to the various models and sizes of forklifts on the market, when encountering an operating environment with limited space, the forklift can easily scratch the side of the bottom cabinet structure during transportation. Once the cabinet surface is scratched, it is easy to rust during subsequent use, seriously affecting the appearance of the product. Summary of the Invention

[0004] The purpose of the present invention is to provide a universal multi-scenario industrial and commercial energy storage cabinet system structure, which is equipped with multiple fixing parts inside, all of which are tightly fixed to the cabinet body structure by bolts. Bolts are also used to connect them to each other, avoiding traditional welding processes to solve the problems raised in the above background.

[0005] To achieve the above objectives, the present invention provides the following technical solutions: a universal multi-scenario industrial and commercial energy storage cabinet system structure, comprising: a cabinet system structure, a liquid cooling unit structure, an energy storage converter PCS structure, a power distribution cabinet structure, a high-voltage box structure, and multiple battery pack assemblies; The cabinet system structure includes: The cabinet body structure and two rubber damping devices are provided with a cabinet bottom beam at the bottom of the cabinet body structure. The two rubber damping devices are respectively installed at the front and rear ends of the cabinet bottom beam by bolts, thereby effectively protecting the cabinet bottom from being scratched by the forklift arm and rusting during the transportation process of the forklift; The inner surface wall of the cabinet body structure is connected by bolts with multiple groups of fixed beam structures, multiple groups of support seat structures, a group of mounting support seats, a group of mounting beams and a group of mounting brackets. The related fixing parts are bolt locking structures, which effectively reduces the impact of the difficulty in assembling the battery pack into the box due to welding deformation.

[0006] Preferably, the rubber damping device includes two L-shaped rubber pads and a U-shaped rubber pad, both of which are wrapped around the outer wall of the cabinet bottom beam.

[0007] Preferably, the outer walls of the two rubber damping devices are in contact with mounting legs, and the two mounting legs are respectively mounted on the front and rear ends of the cabinet bottom beam by bolts, and are located at the same mounting hole position as the rubber damping device.

[0008] Preferably, the two rubber damping devices are made of customized damping rubber material, which can effectively reduce the vibration load during the operation of the energy storage mobile vehicle.

[0009] Preferably, the mounting hole between the mounting leg and the mobile vehicle is an elongated elliptical mounting hole, which can be flexibly installed within the range of the elongated ellipse and has strong installation convenience.

[0010] Preferably, the bottoms of multiple groups of the fixed beam structures are connected to the top of the support seat structure through bolts, and the bottoms of one group of the installation beams are connected to the top of the installation support seat through bolts.

[0011] Preferably, a liquid cooling unit structure is provided at the top left side of the cabinet system structure, and an energy storage converter PCS structure is provided at the bottom left side of the cabinet system structure.

[0012] Preferably, an energy storage converter PCS structure is provided on the top right side of the cabinet system structure, and the energy storage converter PCS structure is bolted to the top of a group of mounting brackets.

[0013] Preferably, a group of mounting brackets are connected to the distribution cabinet structure by bolts, and the high-voltage box structure is connected to a group of mounting support seats and mounting beams by bolts, and the three are in the same mounting hole position.

[0014] Preferably, each set of fixed beam structures and each set of support seat structures are connected to the battery pack assembly through bolts at the same hole position.

[0015] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, the cabinet structure adopts bolt connection instead of welding, which avoids the deformation of the box structure caused by the thermal expansion and contraction of the metal due to the high temperature of welding, ensures the stability and dimensional accuracy of the cabinet structure, and solves the problem of difficulty in assembling the battery into the box. The flexibility and disassembly of the bolt connection significantly improve the assembly efficiency and greatly reduce the cost and difficulty of subsequent maintenance and repair. The universal cabinet structure design realizes "one cabinet for multiple uses", compresses the types of cabinet structures, and constructs a universal adaptation ecology for AC and DC side projects, supports dynamic adjustment of the number of battery pack components and rapid switching of functional modules, and effectively solves the problems of high degree of customization, complex management, and high maintenance costs of traditional cabinet structures.

[0016] In the present invention, rubber damping devices are provided at the front and rear ends of the bottom beam of the energy storage cabinet. When the forklift is used for transportation and the fork is lowered and extended to the vicinity of the cabinet bottom beam, it will first contact the two L-shaped rubber pads and U-shaped rubber pads in the rubber damping device. The soft properties of the rubber can effectively buffer and prevent the fork from directly colliding with the cabinet bottom beam, greatly reducing the risk of scratching the bottom, avoiding rust problems caused by scratches, and effectively ensuring the appearance quality of the product.

[0017] In the present invention, the rubber damping device adopts damping material, which can greatly reduce the vibration transmission rate, reduce the loose connection, cracking of solder joints or performance degradation of electrical components in the cabinet due to vibration, and extend the life of the equipment. The long elliptical mounting hole design allows space for adjustment of the installation position, without the need for precise measurement or secondary processing of the cabinet bottom beam. Moreover, the two adopt a modular design, and a single component can be replaced independently if it is damaged, which reduces maintenance costs and downtime, and improves the maintainability of the equipment.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0021] Reference Figure 1 as well as Figure 5 As shown, the present invention provides a universal multi-scenario industrial and commercial energy storage cabinet system structure, including: a cabinet system structure 1, a liquid cooling unit structure 2, an energy storage converter PCS structure 3, a distribution cabinet structure 4, a high-voltage box structure 5 and multiple battery pack assemblies 6.

[0022] During installation and transportation of industrial and commercial energy storage cabinets, the protective mechanism at the bottom prevents forklifts from scratching the sides of the cabinet structure, ensuring the cabinet's appearance quality and structural integrity. The base also effectively reduces vibration loads, extending the life of the cabinet structure. The internal mechanisms of the cabinet system structure 1 are fixed with bolts, effectively preventing deformation caused by welding. The location and dimensions of the high-voltage box structure 5 and the distribution cabinet structure 4 within the cabinet system structure 1 are compatible with the dimensions of the battery pack assembly 6, meeting the system structure requirements of various projects. When the system receives a charging instruction, the AC power from the power grid first enters the distribution cabinet structure 4 and is distributed to the AC input end of the energy storage converter PCS structure 3. At this time, the energy storage converter PCS structure 3 switches to the rectification mode to efficiently convert the AC power into DC power. At the same time, the built-in controller of the energy storage converter PCS structure 3 dynamically adjusts the output voltage and current according to the set charging strategy. The DC power charges the battery pack assembly 6 through the pre-charging circuit in the cabinet system structure 1. When the battery pack assembly 6 is fully charged, a charging completion signal is sent to the EMS through the communication interface. The energy storage converter PCS structure 3 will reduce the output power. At the same time, the cabinet system structure 1 disconnects the circuit, and the charging process ends.

[0023] In some instances, reference Figure 1 - Figure 2 As shown, the cabinet system structure 1 includes: The cabinet body structure 11 and two rubber damping devices 12 are provided with a cabinet bottom beam at the bottom of the cabinet body structure 11. The two rubber damping devices 12 are respectively installed at the front and rear ends of the cabinet bottom beam by bolts, thereby effectively protecting the cabinet bottom from being scratched by the forklift arm during transportation by the forklift, thereby preventing the forklift arm from rusting and affecting the appearance. The rubber damping device 12 includes two L-shaped rubber pads 121 and a U-shaped rubber pad 122, both of which are wrapped around the outer wall of the cabinet bottom beam. At present, when transporting finished industrial and commercial energy storage cabinets, there are many types and sizes of forklifts on the market. For some situations with limited space, it is easy for the forklift to scratch the side of the bottom cabinet structure during transportation, which in turn causes rust and affects the appearance of the product. The front and rear ends of the bottom beam of the industrial and commercial energy storage cabinet are wrapped with rubber damping devices 12. When the forklift is transporting the industrial and commercial energy storage cabinet, the fork descends and extends forward to the bottom of the cabinet body structure 11 and near the cabinet bottom beam. At this time, the fork first contacts the two L-shaped rubber pads 121 and U-shaped rubber pads 122 in the rubber damping device 12. The rubber prevents the fork from directly contacting the cabinet bottom beam, which can effectively prevent the bottom of the cabinet body structure 11 from being scratched by the fork, causing rust and affecting the appearance. At the same time, the installation hole of the rubber damping device 12 is designed to face outward for easy installation.

[0024] In some instances, reference Figure 2 As shown, the outer walls of the two rubber damping devices 12 are in contact with the mounting legs 13. The two mounting legs 13 are respectively installed on the front and rear ends of the cabinet bottom beam by bolts, and are located in the same mounting hole position as the rubber damping device 12. The two rubber damping devices 12 are made of customized damping rubber materials, which can effectively reduce the vibration load during the operation of the energy storage mobile vehicle. The mounting holes between the mounting legs 13 and the mobile vehicle are 4 long elliptical mounting holes, which can be flexibly installed within the long elliptical range and have strong installation convenience.

[0025] When installing the rubber damping device 12 and the mounting legs 13, the operator first places the two rubber damping devices 12 at the preset positions at the front and rear ends of the cabinet bottom beam, so that the outer surface of the rubber damping device 12 is completely in contact with the bottom beam. Then, the mounting legs 13 are aligned with the placed rubber damping devices 12. The operator needs to hold the mounting legs 13 with both hands so that the mounting holes are initially aligned with the reserved holes on the rubber damping device 12. Then, a positioning pin or a temporary fixing fixture is used for auxiliary positioning. After that, bolts that match the mounting holes are selected and passed through the mounting legs 13 and the rubber damping device 12 in sequence. The operator needs to align the positioning threaded holes on the energy storage mobile vehicle with the elliptical holes of the mounting legs 13. Since the elliptical holes have horizontal and vertical adjustment space, even if there is a slight deviation in the positioning threaded holes, the hole positions can be coincided by fine-tuning the position of the mounting legs 13. After alignment, another bolt passes through the elliptical hole and screws it into the positioning threaded hole. Similarly, manually tighten it until the bolt head contacts the mounting legs 13. Then, use a wrench to preliminarily tighten all the bolts. When the high-frequency vibration generated by the mobile vehicle is transmitted to the rubber damping device 12, the rubber molecular chain converts the vibration energy into heat energy consumption through internal friction, thereby reducing the vibration transmission rate. This feature significantly reduces the loose connection, cracking of solder joints or performance degradation caused by vibration of electrical components in the cabinet, such as battery packs, inverters, controllers, etc., and extends the service life of the equipment. The design of the long elliptical mounting hole further improves the flexibility and efficiency of installation. Compared with the traditional circular mounting hole, the elliptical hole allows the operator to adjust the installation position within a certain range without the need to accurately measure the hole position or perform secondary processing on the cabinet bottom beam. In batch installation scenarios, operators only need to perform rough alignment to complete the installation, which reduces the installation time of a single device and reduces the dependence on the worker's skill level. In addition, the rubber damping device 12 and the mounting leg 13 adopt a modular design, and individual components can be replaced independently when damaged. For example, if the rubber damping device 12 ages or cracks due to long-term use, it can be removed from the mounting leg 13 by simply unscrewing the bolts without replacing the entire vibration damping structure. Similarly, if the mounting leg 13 is deformed due to collision, it can also be replaced with a new part separately. This design reduces maintenance costs and downtime, and improves the maintainability of the equipment.

[0026] In some instances, reference Figure 2 - Figure 5As shown, the inner surface wall of the cabinet body structure 11 is connected by bolts with multiple groups of fixed beam structures 111, multiple groups of support seat structures 112, a group of mounting support seats 113, a group of mounting beams 114 and a group of mounting brackets 115. The related fixing parts are bolt locking structures, which effectively reduce the impact of welding deformation on the difficulty of assembling the battery pack into the box. The bottoms of the multiple groups of fixed beam structures 111 are connected to the top of the support seat structure 112 by bolts, and the bottoms of a group of mounting beams 114 are connected to the top of the mounting support seat 113 by bolts.

[0027] A plurality of identical side holes are provided inside the cabinet body structure 11, and the relevant fixed support structure is fixed to the cabinet column through the side holes. The fixed beam structure 111 and the support seat structure 112, the mounting support seat 113 and the mounting beam 114 and the mounting bracket 115 respectively constitute three fixing parts. Each support seat structure 112 is fixed to the bottom of the fixed beam structure 111, and each mounting support seat 113 is fixed to the bottom of the mounting support seat 113. Both are triangular, and both enhance the structural stability and bearing capacity of the beam. The above-mentioned fixing parts are fixed to the cabinet body structure 11 by bolts, and are also connected to each other by bolts. The upper and lower double-layer structures are locked, which reduces the problem of deformation of the box structure caused by excessive welding. In the traditional welding process, the high temperature generated by welding will cause the metal material to expand and contract with heat. , which can easily lead to varying degrees of deformation of the cabinet structure and affect the dimensional accuracy and appearance quality of the cabinet. The non-welded structure is connected by bolts, which avoids the influence of high temperature on the material, effectively ensures the stability and dimensional accuracy of the cabinet structure, and solves the problem of difficult battery assembly. Since the non-welded structure has high flexibility and disassembly, during the assembly of the relevant structure into the box, the position and angle of the fixings can be easily adjusted according to actual needs, providing a more spacious and convenient space for the installation of the structure, and improving the assembly efficiency and quality. At the same time, in the subsequent maintenance and overhaul process, the non-welded structure also facilitates the disassembly and replacement of internal components of the cabinet, reducing maintenance costs and difficulty. The entire operation process has a simple structure and flexible installation, which can meet the assembly needs of battery cabinets in different scenarios.

[0028] In some instances, reference Figure 1 as well as Figure 2 - Figure 5As shown, a liquid cooling unit structure 2 is provided at the top left side of the cabinet system structure 1, a storage converter PCS structure 3 is provided at the bottom left side of the cabinet system structure 1, and a storage converter PCS structure 3 is provided at the top right side of the cabinet system structure 1. The storage converter PCS structure 3 is bolted to the top of a group of mounting brackets 115, a group of mounting brackets 115 are connected to the distribution cabinet structure 4 by bolts, and the high-voltage box structure 5 is connected to a group of mounting support bases 113 and mounting beams 114 by bolts, and the three are in the same mounting hole position, and each group of fixed beam structures 111 and each group of support base structures 112 are connected to the battery pack assembly 6 by bolts at the same hole position.

[0029] At the project startup stage, technical personnel must first clarify the functional positioning of the industrial and commercial cabinet according to customer needs. If the project is an industrial and commercial cabinet with an AC side, such as a storage system that needs to be connected to the power grid or load, the distribution cabinet structure 4 and the high-voltage box structure 5 must be configured in the cabinet structure at the same time. If the project is a high-capacity industrial and commercial cabinet with only a DC side, such as only a storage battery pack is needed to power DC equipment, only the battery pack assembly 6 needs to be installed, and then the cabinet space allocation link is entered. The installation area of ​​the high-voltage box structure 5 and the distribution cabinet structure 4 above the battery pack assembly 6 is strictly designed based on the size of a single battery pack assembly 6, and the space in this area is twice that of a single battery pack assembly 6. This design allows the reserved space to be directly used when the DC side project needs to add a battery pack assembly 6. The stacking installation is carried out without any modification to the cabinet structure, and then the component installation work is carried out. For projects with AC side, the operator needs to install the distribution cabinet structure 4 first, place the distribution cabinet structure 4 in the designed position, ensure that its reserved holes completely coincide with the reserved holes of the mounting bracket 115, and then use bolts to fix the distribution cabinet and the cabinet frame. After the distribution cabinet is installed, the high-voltage box structure 5 is installed: place the high-voltage box structure 5 above a set of mounting beams 114 so that the reserved holes coincide with the reserved holes of the mounting beams 114 and the mounting support seat 113, and then use high-strength bolts to pass through the three reserved holes at the same time to fix the high-voltage box structure 5, and then carry out the adaptation installation of the battery pack assembly 6. The operator can directly place it on the fixed beam structure 11 1 top, and then use bolts to lock the battery pack assembly 6 with the fixed beam structure 111 and the support base structure 112. The operator can install the corresponding number of battery pack assemblies 6 according to the actual situation. In the DC side project, the distribution cabinet structure 4 and the high-voltage box structure 5 need to be removed, and only the battery pack assembly 6 needs to be installed. If the installation space of the battery pack assembly 6 is insufficient, it can be installed inside the space created by removing the distribution cabinet structure 4 and the high-voltage box structure 5. This universal cabinet structure design realizes the ultimate goal of "one cabinet for multiple uses". Through standardized installation space and modular component design, it completely breaks the customization dilemma of "one cabinet for one project" in traditional industrial and commercial cabinet projects. In terms of management costs, the cabinet structures of different projects under the traditional model need to be stored separately due to functional differences. The AC side cabinets and DC side cabinets need to be stored in separate areas, and maintenance requires the deployment of different professional maintenance teams. Updates require tracking of technical iterations of multiple cabinet types, resulting in a wide variety of inventory types that are easy to confuse. However, this solution compresses the types of cabinet structures to the smallest unit by unifying the cabinet frame and standardizing the installation space. Inventory management only needs to distinguish between the two major categories of "basic cabinets" and "optional components". In addition, changes in the number of battery pack components 6 under the DC side configuration do not involve changes in the cabinet structure, further simplifying the management process. In terms of maintenance efficiency, the universal design means that maintenance personnel do not need to master the maintenance skills of multiple cabinet structures. For example, when the distribution cabinet structure 4 fails, regardless of whether the cabinet is used for AC or DC side projects, maintenance personnel can operate according to the unified maintenance manual.The steps from component removal, troubleshooting, to replacement and installation are completely consistent, significantly shortening maintenance training cycles and troubleshooting time. This industrial and commercial cabinet system structure, through modular layout, standardized installation space, and flexible component configuration solutions, creates a complete ecosystem for universal adaptation of AC and DC side projects. It also supports dynamic adjustment of the number of battery pack components and rapid switching of functional modules, effectively solving the problems of traditional cabinet structures with high customization, complex management, and high maintenance costs.

[0030] The wiring diagrams of the liquid cooling unit structure 2, the energy storage converter PCS structure 3, the power distribution cabinet structure 4, the high-voltage box structure 5 and the battery pack assembly 6 in the present invention are common knowledge in the field, and their working principles are already known technologies. The models are selected according to actual use, so the control method and wiring layout of the liquid cooling unit structure 2, the energy storage converter PCS structure 3, the power distribution cabinet structure 4, the high-voltage box structure 5 and the battery pack assembly 6 will no longer be explained in detail.

[0031] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
