Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage systems, and in particular relates to an energy storage converter module device for protecting energy storage systems. Background Art

[0002] The energy storage converter module is primarily responsible for converting electrical energy within the energy storage system. Its core function is to convert direct current (DC) into alternating current (AC), and vice versa. This conversion enables the energy storage system to seamlessly connect to the existing AC grid, enabling the storage and release of electrical energy. Furthermore, the energy storage converter module controls the output voltage amplitude and frequency to ensure compatibility with the grid, and adjusts output power based on the grid's real-time needs or operational instructions to protect the energy storage system.

[0003] For example, the energy storage converter module with Chinese application number 202221001107.4 includes a chassis assembly, a copper busbar assembly, an electrical assembly, a radiator, and a main control board. The chassis assembly includes a housing, a front panel, a top cover, left and right hanging ears, left and right brackets for the main control sheet metal, a power board mounting plate, an AC / DC conversion mounting plate, a fan assembly, a main control board mounting plate, and a power supply mounting plate. The energy storage converter module provided by this new invention dissipates heat from power devices through a fan assembly and a radiator. In existing energy storage devices, the fan assembly is easily damaged due to long-term operation and therefore needs to be disassembled and replaced. The fan assembly is installed on the inner wall of the housing, and the fan assembly and the inner wall of the housing are detachably connected. Then, the housing is separated from the other components of the energy storage converter module, and the fan assembly can be disassembled and assembled, making disassembly and assembly of the fan assembly more convenient.

[0004] At present, although the above-mentioned existing energy storage inverter module can disassemble and assemble the fan assembly, making the disassembly and assembly of the fan assembly more convenient, during use, the energy storage inverter module is in an external environment for a long time due to insufficient protection design. It is very easy to cause its surface to be scratched or physically damaged due to the unexpected action of external forces. This situation inevitably shortens the overall service life of the energy storage inverter module.

[0005] Therefore, based on the above problems, we designed an energy storage converter module device for energy storage system protection. Utility Model Content

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes an energy storage converter module device for protecting an energy storage system. This device solves the technical problem that, due to deficiencies in the protection design of existing energy storage converter modules, the surface of the modules is easily scratched or physically damaged by unexpected external forces, resulting in a shorter overall service life of the modules.

[0007] To achieve the above-mentioned object, according to an embodiment of the first aspect of the present utility model, an energy storage converter module device for protecting an energy storage system is provided, comprising a protective shell and an energy storage converter module body disposed in the protective shell;

[0008] The protective shell includes an upper half shell and a lower half shell, and a reinforcement layer is provided inside the upper half shell and the lower half shell, and a metal reinforcement sheet is provided inside the reinforcement layer;

[0009] The inner walls of the upper and lower half shells are provided with ferrules;

[0010] Also includes:

[0011] The protective frame is inserted into the side of the protective shell, and a protective grid is arranged in the port of the protective frame.

[0012] A further improvement is that a clamping block is provided at the four corners of the back of each ferrule, and the upper half shell, the lower half shell and each ferrule are all U-shaped.

[0013] A further improvement is that the inner walls of the upper half shell and the lower half shell are provided with mounting slots at the position of each card block, and adsorption magnetic blocks are provided on the card block and in the mounting slots.

[0014] A further improvement is that heat-conducting columns are fixedly inserted into both sides of the upper half shell and the lower half shell, and the ends of the heat-conducting columns are connected to the ferrules. The heat-conducting columns and the ferrules are both made of aluminum.

[0015] A further improvement is that mounting seats are provided at the four corners of the upper half shell and the lower half shell, and the mounting seats of the upper half shell and the lower half shell are connected by fixing bolts.

[0016] A further improvement is that a notch is opened on the same side surface of the upper half shell and the lower half shell, and mounting holes are set at the four corners of the notch. The guard frame is inserted into the notch and connected to the notch by fixing screws.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] The utility model realizes the rapid disassembly and assembly of the ferrules by inserting a pair of ferrules into the preset installation slots inside the upper and lower shells through the ferrules on the back side, and utilizing the magnetic adhesion between the ferrules and the adsorption magnetic blocks in the slots, which greatly facilitates the flexible protection of module bodies of different specifications and broadens the scope of application.

[0019] Through the design of the protective housing, protective frame, and built-in protective grid, this utility model provides a protective barrier for the energy storage converter module, effectively resisting impact and scratches from unexpected external forces. Furthermore, the metal reinforcement plate integrated within the protective housing significantly enhances the overall structural strength of the module, making it resistant to external forces and less susceptible to deformation and damage, thereby significantly extending the overall service life of the energy storage converter module.

[0025] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 3 As shown, an energy storage converter module device for protecting an energy storage system includes a protective shell 1 and an energy storage converter module body 3 arranged in the protective shell 1;

[0027] The protective shell 1 includes an upper half shell 11 and a lower half shell 13. A reinforcement layer is provided inside the upper half shell 11 and the lower half shell 13, and a metal reinforcement sheet 14 is provided inside the reinforcement layer.

[0028] The inner walls of the upper half shell 11 and the lower half shell 13 are provided with a clamping sleeve 4. The upper half shell 11, the lower half shell 13 and each clamping sleeve 4 are all U-shaped, which is convenient for wrapping the energy storage converter module body 3;

[0029] Specifically, as a preferred embodiment, a card block 41 is provided at the four corners of the back of each ferrule 4, and a mounting slot 42 is opened on the inner wall of the upper half shell 11 and the lower half shell 13 at the position of each card block 41, and an adsorption magnetic block 43 is provided on the card block 41 and in the mounting slot 42. When installing, the card blocks 41 on the back of a pair of ferrules 4 are respectively correspondingly clamped in the mounting slots 42 inside the upper half shell 11 and the lower half shell 13, so that the card blocks 41 and the adsorption magnetic blocks 43 in the mounting slots 42 adhere to each other, thereby realizing convenient disassembly and assembly of the ferrule 4;

[0030] Specifically, as a preferred embodiment, heat-conducting columns 16 are fixedly inserted into both sides of the upper half shell 11 and the lower half shell 13, and the ends of the heat-conducting columns 16 are connected to the ferrule 4. The heat-conducting columns 16 and the ferrule 4 are both made of aluminum. The heat-conducting columns 16 are used to conduct heat from the energy storage converter module body 3.

[0031] Specifically, as a preferred embodiment, mounting seats 12 are provided at the four corners of the upper half shell 11 and the lower half shell 13. The mounting seats 12 of the upper half shell 11 and the lower half shell 13 are connected by fixing bolts, so that the protective shell 1 can be conveniently disassembled and assembled, and the internal energy storage converter module body 3 can be easily removed for maintenance.

[0032] like Figure 1 and Figure 3 As shown, when implemented, it includes: a protective frame 2, which is inserted into the side of the protective shell 1, and a protective grid 21 is provided in the port of the protective frame 2;

[0033] Specifically, as a preferred embodiment, a notch 15 is opened on the same side of the upper half shell 11 and the lower half shell 13, and mounting holes 151 are set at the four corners of the notch 15. The protective frame 2 is inserted into the notch 15 and is connected in the notch 15 by fixing screws, so that the protective frame 2 can be easily disassembled and assembled.

[0034] like Figures 1 to 3As shown, in this embodiment, it should also be noted that the working principle of the energy storage converter module in the application document is mainly based on power electronics technology and energy storage technology. It first receives DC power from the energy storage system and then converts the DC power into high-frequency AC power through the internal DC / AC bidirectional converter. During this process, the converter will control the voltage, frequency, and power of the output AC power by adjusting the on and off time of the switch tube according to the instructions of the control unit. The converted high-frequency AC power is then filtered by the filter to remove the high-frequency harmonic components to obtain AC power that meets the requirements, thereby realizing the protection function of the energy storage system. The energy storage converter module realizes the protection function based on the disclosed working principle. When assembling the energy storage converter module device, the heat dissipation port of the module is placed on the side facing the protective frame 2, and the connector of the module is located on the other side of the protective shell, with a connector outlet slot pre-reserved.

[0035] In addition, it should be noted that this application document only addresses the shortcomings of existing energy storage converter modules due to insufficient protection design, which makes it very easy for the surface to be scratched or physically damaged by accidental external forces, resulting in a shorter overall service life of the energy storage converter modules, that is, poor protection effect. It does not involve improvements in other aspects. The following is an introduction to the working principle of the energy storage converter module device for energy storage system protection:

[0036] During installation and use, the on-site operator selects a pair of ferrules 4 according to the specific specifications of the energy storage inverter module body 3, and inserts the pair of ferrules 4 into the preset installation slots 42 inside the upper half shell 11 and the lower half shell 13 through the card blocks 41 on the back thereof, and utilizes the magnetic adhesion between the card blocks 41 and the adsorption magnetic blocks 43 in the card slots to achieve rapid disassembly and assembly of the ferrules 4, which greatly facilitates the flexible protection of module bodies of different specifications and broadens the scope of application.

[0037] Next, securely place the energy storage converter module body 3 onto the ferrule 4 within the lower half-shell 13, and then close the upper half-shell 11. Securely connect the upper half-shell 11 to the mounting base 12 on the lower half-shell 13 with fixing bolts to ensure structural stability. Next, align the protective frame 2 with the notch 15 and insert it, securing it securely within the notch 15 with fixing screws. This completes the assembly of the entire energy storage converter module.

[0038] This design cleverly utilizes the protective housing 1, protective frame 2, and its built-in protective grid 21 to provide a protective barrier for the energy storage converter module body 3, effectively resisting impact and scratches from unexpected external forces. Furthermore, the metal reinforcement sheet 14 integrated within the protective housing 1 significantly enhances the overall structural strength of the module, making it resilient to external forces and deformation and damage, thereby significantly extending the overall service life of the energy storage converter module.

[0039] The above embodiments are only used to illustrate the technical method of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
