Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, and in particular to an outdoor energy storage cabinet. Background Technology

[0002] Outdoor energy storage cabinets are devices used in outdoor environments to store electrical energy. Their main function is to store electrical energy when the power supply is sufficient and then release this electrical energy when the power demand is high or when the power is insufficient.

[0003] Currently, outdoor energy storage cabinets may generate high-frequency electromagnetic waves during operation. These waves can conduct or radiate outwards, interfering with the operation of other equipment. Therefore, outdoor energy storage cabinets typically possess high protection levels and electromagnetic compatibility (EMC) shielding capabilities. However, existing outdoor energy storage cabinets have the following drawbacks: Current shielding primarily relies on the combination of the cabinet door and body to form internal shielding. Gaps at this junction create electromagnetic leakage points, resulting in discontinuous shielding and low shielding effectiveness. This leads to poor EMC shielding performance. Utility Model Content

[0043] The following reference Figures 1 to 5 This invention introduces the outdoor energy storage cabinet provided by this utility model.

[0044] This embodiment provides an outdoor energy storage cabinet for storing electrical energy in an outdoor environment, which can effectively improve electromagnetic compatibility shielding function.

[0045] Please refer to Figure 1 Specifically, the outdoor energy storage cabinet includes a cabinet body 10, a cabinet door 20, and a conductive sealing ring 30; the inner peripheral wall of the cabinet body 10 is provided with a first shielding structure 40, and the first shielding structure 40 is electrically connected to the cabinet body 10; the cabinet door 20 is connected to the cabinet body 10 and opens or closes the opening of the cabinet body 10, and the side of the cabinet door 20 facing the cabinet body 10 is provided with a second shielding structure 50, and the second shielding structure 50 is electrically connected to the cabinet door 20; the conductive sealing ring 30 is sandwiched between the cabinet body 10 and the cabinet door 20 to seal the gap between the cabinet body 10 and the cabinet door 20, and the cabinet body 10 is electrically connected to the cabinet door 20 through the conductive sealing ring 30.

[0046] In this embodiment, the outdoor energy storage cabinet employs a conductive sealing ring 30 sandwiched between the cabinet body 10 and the cabinet door 20. When the cabinet body 10 and the cabinet door 20 are closed, they are electrically connected through the conductive sealing ring 30. At this time, the conductive sealing ring 30 forms a fully enclosed shielding layer, sealing the gap between the cabinet body 10 and the cabinet door 20, thus maintaining a fully enclosed electromagnetic shielding structure with excellent shielding effect. Furthermore, an additional first shielding structure 40 is added inside the cabinet body 10, increasing the shielding effectiveness of the cabinet body 10. An additional second shielding structure 50 is added to the cabinet door 20, increasing the shielding performance of the cabinet door 20. Therefore, under the combined shielding effect of the cabinet body 10, the cabinet door 20, the conductive sealing ring 30, the first shielding structure 40, and the second shielding structure 50, the shielding effectiveness of the outdoor energy storage cabinet is effectively improved, thereby effectively enhancing its electromagnetic compatibility shielding function.

[0047] Specifically, the first shielding structure 40 is used to shield the inner peripheral wall of the cabinet 10, thus adding another shielding layer to the inner peripheral wall of the cabinet 10, effectively ensuring conductivity and continuity, and improving shielding effectiveness. The second shielding structure 50 is used to shield the inner wall of the cabinet door 20, that is, the side of the cabinet door 20 facing the cabinet 10, thus adding another shielding layer to the inner wall of the cabinet door 20, preventing electromagnetic leakage points from appearing at the holes where other components are installed on the cabinet door 20, effectively ensuring conductivity and continuity, and improving shielding effectiveness.

[0048] More specifically, a fully enclosed shielding cage is formed by the cabinet door 20, cabinet body 10, first shielding structure 40, second shielding structure 50 and conductive sealing ring 30, forming a Faraday cage effect. The conductivity and conductivity continuity of the shielding cage are better, thereby effectively improving the shielding effectiveness, and the shielding effectiveness is not less than 60dB (30MHz-1GHz).

[0049] In this embodiment, the cabinet 10 is a device for storing electrical energy with an opening on one side. One end of the cabinet door 20 is hinged to the cabinet 10, and the other end is locked to the cabinet 10 via a locking structure, thus enabling the opening and closing of the cabinet 10 and locking the cabinet 10 in the closed state. The locking structure uses a fixed pin, latch, or other locking mechanism. It is understood that the number of locking structures can be adaptively set according to the actual structure and is not specifically limited here.

[0050] Specifically, both the cabinet body 10 and the cabinet door 20 are made of stainless steel, which has strong corrosion resistance, high load-bearing capacity, weather resistance, and impact resistance. It is also waterproof, moisture-proof, and high-temperature resistant, making it suitable for outdoor use. Furthermore, the cabinet body 10 achieves grounding of the outdoor energy storage cabinet through direct contact with the ground, which also grounds all structures electrically connected to the cabinet body 10 and the cabinet door 20, thereby achieving electromagnetic compatibility shielding within the outdoor energy storage cabinet.

[0051] Please refer to Figure 2 Furthermore, the conductive sealing ring 30 includes an elastic sealing structure 31 and a conductive structure 32. The first end of the elastic sealing structure 31 is connected to the cabinet body 10, and the second end faces the cabinet door 20. Both ends of the elastic sealing structure 31 have gaps. The conductive structure 32 is embedded within the elastic sealing structure 31, with its two ends filling the two gaps and respectively providing conductive connections to the cabinet body 10 and the cabinet door 20. It is understood that under the clamping of the cabinet body 10 and the cabinet door 20, the elastic sealing structure 31 will be compressed due to its elasticity. In this embodiment, by embedding the conductive structure 32 within the elastic sealing structure 31, not only is a seal achieved between the cabinet body 10 and the cabinet door 20, but also a conductive connection is established between them, effectively reducing the penetration of electromagnetic waves and thus helping to form a fully enclosed shielding layer, preventing electromagnetic leakage points.

[0052] Optionally, the projection of the elastic sealing structure 31 surrounds the opening of the cabinet 10, which can achieve full enclosure of the outer periphery of the opening, thereby achieving good sealing and full-enclosure shielding effect for the cabinet 10 and the cabinet door 20.

[0053] Specifically, the elastic sealing structure 31 is provided with at least two buffer channels 311 spaced apart along its own center line, so that the elastic sealing structure 31 has good compression performance and ensures that the electrical connection between the conductive structure 32 and the cabinet 10 and the cabinet door 20 is stable and reliable.

[0054] Optionally, the elastic sealing structure 31 is made of sealing materials such as nitrile rubber, which can meet its sealing requirements. For example, the elastic sealing structure 31 in this embodiment is made of EPDM (ethylene propylene diene monomer) solid rubber, which has the characteristics of aging resistance, corrosion resistance, and high elasticity, and has a wider range of applications and a longer service life.

[0055] Specifically, the conductive structure 32 includes a conductive connector 322 and two conductive foams 321. The two conductive foams 321 fill two gaps respectively; one of the two conductive foams 321 is used for conductive connection with the cabinet door 20, and the other is used for conductive connection with the cabinet body 10. The conductive connector 322 includes an extension 3221 and two connecting portions 3222. The two connecting portions 3222 are respectively located at the first and second ends of the extension 3221. One of the two connecting portions 3222 is embedded within one of the two conductive foams 321, and the other of the two connecting portions 3222 is embedded within the other of the two conductive foams 321. The two conductive foams 321 enable conductive connections between the conductive structure 32 and the cabinet body 10 and the cabinet door 20, respectively. The conductive connector 322 enables conductive connections between the two conductive foams 321, thereby achieving a conductive connection between the cabinet body 10 and the cabinet door 20. Furthermore, the extension 3221 can deform when the elastic sealing structure 31 is compressed without affecting its conductivity and connectivity.

[0056] Optionally, the conductive foam 321 is made of a composite material that combines conductive materials and foam structure, which takes into account conductivity, flexibility and processing stability.

[0057] Optionally, the conductive connector 322 is made of tin-plated copper mesh, which has good conductivity and is elastic and flexible, and will not be damaged by the compression of the elastic sealing structure 31, thereby improving the reliability of the conductive structure 32.

[0058] Specifically, the conductive connector 322 also includes a reinforcing portion 3223 connected to the extension portion 3221. The reinforcing portion 3223 is located between the two connecting portions 3222 along the axial direction of the extension portion 3221, and the reinforcing portion 3223 is embedded in the elastic sealing structure 31 to enhance the connection strength between the conductive connector 322 and the elastic sealing structure 31, and also to further limit the conductive connector 322.

[0059] More specifically, the reinforcing part 3223 is embedded between the two buffer channels 311, that is, the connection to the conductive connector 322 is added in the middle of the elastic sealing structure 31, so that the connection and force between the two are more uniform.

[0060] Specifically, the conductive sealing ring 30 also includes a dovetail groove 33, which is connected to the cabinet 10. The first end of the elastic sealing structure 31 is engaged in the dovetail groove 33. This allows for the fixation of the elastic sealing structure 31. The use of the dovetail groove 33 for fixation enhances the connection between the cabinet 10 and the conductive sealing ring 30, effectively preventing the elastic sealing structure 31 from falling off the cabinet 10, improving reliability, enhancing the safety and reliability of the conductive sealing ring 30, and simplifying the installation process.

[0061] Optionally, the outer peripheral wall of the first end of the elastic sealing structure 31 is provided with a first limiting part 312 and a second limiting part 313. The first limiting part 312 abuts against the inner wall of the bottom of the dovetail groove 33, and the second limiting part 313 abuts against the inner wall of the dovetail groove 33 away from the inner wall of the bottom. In this embodiment, the first limiting part 312 can form a seal with the inner wall of the bottom of the dovetail groove 33, effectively ensuring the stable and reliable sealing of the cabinet door 20 and the cabinet body 10; through the second limiting part 313, the outer peripheral wall of the first end of the elastic sealing structure 31 forms a barbed structure, realizing the snap-fit ​​between the first end of the elastic sealing structure 31 and the dovetail groove 33, making the connection between the two stable and reliable.

[0062] Optionally, the second end of the elastic sealing structure 31 is provided with a third limiting part 314, which can be clamped between the outer wall of the dovetail groove 33 away from the inner wall of the groove bottom and the cabinet door 20; so that the second end of the elastic sealing structure 31 will not be compressed into the dovetail groove 33 during the compression process, thus preventing the cabinet door 20 and the cabinet 10 from having no sealing structure and resulting in ineffective sealing, thereby improving the reliability of the conductive sealing ring 30.

[0063] More specifically, the dovetail groove 33 includes a mounting groove 331, which is located on the side of the dovetail groove 33 facing the cabinet door 20. The first end of the elastic sealing structure 31 is engaged with the mounting groove 331 to achieve the engagement and fixation of the two.

[0064] Optionally, the dovetail groove 33 and the cabinet 10 can be connected by welding, bonding, or other methods, without specific limitations. For example, the dovetail groove 33 and the cabinet 10 are fixed by welding, which improves the stability of the connection between the two.

[0065] Please return to the reference. Figure 1Furthermore, the first shielding structure 40 includes a shielding top plate (not shown in the figure), a shielding bottom plate 41, and a shielding side plate 42. The shielding top plate is connected to the inner top wall of the cabinet 10, the shielding bottom plate 41 is connected to the inner bottom wall of the cabinet 10, and the shielding side plate 42 is connected to the inner side wall of the cabinet 10. The shielding top plate and the shielding bottom plate 41 are respectively connected to the two ends of the shielding side plate 42. By setting corresponding shielding structures on each inner wall of the cabinet 10, the effective shielding of the inner peripheral wall of the cabinet 10 is achieved, thereby realizing the full-enclosed shielding inside the cabinet 10 and further improving the shielding effectiveness.

[0066] Specifically, there are three shielding side panels 42 so that each inner wall of the cabinet 10 is shielded.

[0067] Furthermore, the second shielding structure 50 includes a shielding plate connected to the side of the cabinet door 20 facing the cabinet body 10, thereby forming the second shielding structure 50 and shielding the inner wall of the cabinet door 20.

[0068] Optionally, the shielding top plate, shielding bottom plate 41, shielding side plate 42 and shielding plate are all made of galvanized steel plate, which has anti-corrosion properties, high practicality and can be used as a better shielding structure.

[0069] Alternatively, the shielding top plate, shielding bottom plate 41, shielding side plate 42, and shielding plate are all provided with heat dissipation holes to provide good heat dissipation performance.

[0070] Alternatively, the shielding top plate, shielding bottom plate 41, shielding side plate 42, and shielding plate are all made of honeycomb-shaped galvanized steel sheet, which provides good heat dissipation while also providing shielding. For example, the shielding top plate, shielding bottom plate 41, shielding side plate 42, and shielding plate are all made of honeycomb-shaped galvanized steel sheet with a hole diameter of 6mm and a hole spacing of 10mm.

[0071] Optionally, the first shielding structure 40 and the inner peripheral wall of the cabinet 10, the shielding top plate and the shielding side plate 42, and the shielding bottom plate 41 and the shielding side plate 42 are all connected by welding, so that the first shielding structure 40 inside the cabinet 10 can be formed, which makes the conductivity of the inner peripheral wall of the cabinet 10 better and avoids electromagnetic leakage points.

[0072] Please refer to Figure 1 and Figure 3In this embodiment, the outdoor energy storage cabinet also includes a hinge 60. The first end of the hinge 60 is connected to the cabinet body 10, and the second end is connected to the cabinet door 20. The hinge 60 is used to hinge the cabinet body 10 and the cabinet door 20. The conductivity of the hinge 60 is higher than that of the cabinet body 10 and the cabinet door 20, which greatly reduces the contact resistance between the hinge 60 and the cabinet body 10, effectively reducing the penetration of electromagnetic waves and thus further improving the shielding effectiveness.

[0073] Since the cabinet body 10 and cabinet door 20 are made of stainless steel, and optionally, the hinge 60 is made of copper alloy, the conductivity is greatly improved, thereby achieving a conductive connection between the cabinet body 10 and the cabinet door 20 and reducing the contact resistance between them. For example, in actual use, the contact resistance between the hinge 60 and the cabinet body 10 is less than 0.01Ω, which further improves the shielding effectiveness.

[0074] Specifically, the hinge 60 includes a fixed hinge 62, a movable hinge 63, and a pin 64. The fixed hinge 62 is fixedly connected to the cabinet body 10, the movable hinge 63 is rotatably connected to the fixed hinge 62 through the pin 64, and the movable hinge 63 is fixedly connected to the cabinet door 20, thus realizing the hinge connection between the cabinet body 10 and the cabinet door 20.

[0075] Optionally, the fixed hinge 62 is fixedly connected to the cabinet body 10, and the movable hinge 63 is fixedly connected to the cabinet door 20, so that the two are fixedly connected, and the connection effect is better in terms of heat exchange and electrical conductivity.

[0076] More specifically, the cabinet 10 is provided with a connecting liner 61, and a hinge 60 is provided on the connecting liner 61. The conductivity of the connecting liner 61 is greater than that of the hinge 60, which further increases the conductivity between the hinge 60 and the cabinet 10, effectively reducing the penetration of electromagnetic waves and thus improving the shielding effectiveness. Specifically, a fixed hinge 62 is provided on the connecting liner 61.

[0077] Optionally, the connecting liner 61 can be made of silver-plated copper liner, which can improve conductivity, thereby increasing the conductivity between the hinge 60 and the cabinet 10 and effectively reducing the penetration of electromagnetic waves.

[0078] Please refer to Figure 4 and Figure 5Optionally, the area of ​​the cabinet body 10 where the hinge 60 is installed is provided with a rust-proof conductive film 70, and / or the area of ​​the cabinet door 20 for contacting the conductive sealing ring 30 is provided with a rust-proof conductive film 70. This achieves rust prevention for the cabinet body 10 and the cabinet door 20, ensures effective conductive connection between the hinge 60 and the cabinet body 10, and / or ensures effective conductive connection between the cabinet door 20 and the conductive sealing ring 30. Exemplarily, in this embodiment, the area of ​​the cabinet body 10 where the hinge 60 is installed is provided with a rust-proof conductive film 70, and the area of ​​the cabinet door 20 for contacting the conductive sealing ring 30 is provided with a rust-proof conductive film 70, making the use of the hinge 60 and the conductive sealing ring 30 more reliable.

[0079] In this embodiment, the outdoor energy storage cabinet uses H65 copper alloy hinges for hinge 60, silver-plated copper liner for connecting plate 61, and conductive sealing ring 30 including an elastic sealing structure 31 made of EPDM and a conductive structure 32 made of conductive foam 321 and tin-plated copper mesh layer, and is fixed to the cabinet body 10 by dovetail groove 33. Taking the above-mentioned outdoor energy storage cabinet as an example, when the conductive sealing ring 30 is compressed to a compression rate of 30%, its electromagnetic compatibility shielding effectiveness is 65dB (500MHz). Under a 48-hour continuous high temperature test at 70℃, the deformation of the cabinet door 20 is less than 0.3mm, and the protection level can reach IP65, which meets the requirements of the outdoor energy storage cabinet and has high shielding effectiveness.

[0080] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
