Description

Technical Field

[0001] This utility model relates to the field of marine technology, and in particular to an energy storage system and an electrical device. Background Technology

[0002] Currently, lithium-ion battery energy storage systems are commonly used on ships to replace conventional lead-acid battery energy storage systems, addressing the issues of low capacity, heavy weight, and large size associated with lead-acid systems. However, marine energy storage systems are mostly located in ship hulls, making large-scale disassembly impossible. Access doors are necessary for maintenance, but in ships with irregularly shaped hull sections, the battery racks vary in shape and size, making it difficult to move them in and out through the access doors for repairs. Therefore, battery racks must be installed during hull construction, allowing smaller battery boxes to be installed after completion. When adjusting or replacing the battery packs, maintenance personnel must enter the hull and manually move cables and battery boxes in and out, which is time-consuming and labor-intensive. Furthermore, maintenance access channels must be provided within the hull for personnel, but these channels occupy even more space. Moreover, adjusting the power capacity requires correspondingly expanding or shrinking the overall hull space to accommodate the battery packs, but current adjustment methods are limited and difficult to implement. Therefore, how to achieve quick assembly and disassembly of the battery rack, facilitating external maintenance and replacement, and making the addition and removal of battery boxes convenient and controllable are problems that need to be solved by people in this field.

[0042] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and specific implementation methods.

[0043] like Figures 1-12 This embodiment provides an energy storage system with a housing 100, including multiple battery racks 10, a guide rail assembly 20, and multiple connecting components. The guide rail assembly 20 includes a guide rail 22, which can be fixed in the housing 100 and extends along a first direction. The guide rail 22 has multiple battery rack fixing positions, and each battery rack 10 can slide along the first direction to the corresponding battery rack fixing position on the guide rail 22. The multiple connecting components are arranged one-to-one with the multiple battery rack fixing positions, and the connecting components are used to fix the battery rack 10 that has slid to the corresponding battery rack fixing position inside the housing 100.

[0044] Specifically, in this embodiment, multiple battery racks 10 are sequentially slidably arranged on the guide rail 22 of the guide rail assembly 20 along the first direction. They can be fixed after being assembled into the corresponding battery rack fixing position on the guide rail 22 by the connecting component. This not only enables the rapid pushing and pulling of multiple battery racks 10, making it convenient for personnel to guide the battery racks 10 along the guide rail assembly 20 to the outside for maintenance and replacement, thus improving safety and convenience, but also allows for the adjustment of power capacity by simply increasing or decreasing the number of battery racks 10 and lengthening or shortening the guide rail 22. This facilitates operation, avoids the need to reserve maintenance channels, and improves the overall space utilization of the cabin 100.

[0045] The specific structure of the energy storage system in this embodiment will be described below.

[0046] like Figures 1-6As shown, in this embodiment, the energy storage system is housed within the cabin 100, and includes multiple battery racks 10, a guide rail assembly 20, supports, and connecting components. Specifically, the length direction of the cabin 100 is designated as the first direction, the height direction as the second direction, and the width direction as the third direction, with each of the three directions being perpendicular to the others. Optionally, the guide rail assembly 20 is fixed to the cabin 100, and the multiple battery racks 10 are sequentially slidably mounted on the guide rail assembly 20 along the first direction. This allows the multiple battery racks 10 to be installed sequentially within the cabin 100 along its length and to be quickly removed in the reverse direction, enabling quick installation and removal of the battery racks 10. This facilitates maintenance and battery replacement, and the amount of power can be increased or decreased by changing the number of battery racks 10 or the length of the cabin 100, making operation simple.

[0047] Furthermore, in this embodiment, the connection assembly includes multiple connectors. At least one side of the battery rack 10 along the second direction can be fixed to the cabin 100 by at least some of the connectors, and / or, at least one side of the battery rack 10 along the third direction can be fixed to the cabin 100 by at least some of the connectors. This ensures that at least one side of the battery rack 10 is fixed circumferentially, guaranteeing stable installation of the battery rack 10 within the cabin 100. Furthermore, the energy storage system also includes a support, one end of which can be fixed to the inner wall of the cabin 100, and the other end is detachably connected to a connector to ensure the stability of the connector, thereby improving the stability of the battery rack 10 after installation.

[0048] For example, after the battery racks 10 are assembled to their respective positions on the guide rail assembly 20, they are fixed within the hull 100 by connecting them to the support, thereby ensuring that the battery racks 10 can be stably placed and will not move during the operation of the hull. For example, the connection assembly and the support are detachable to facilitate the installation and removal of the battery racks 10. Specifically, the connection assembly includes a first connector 50, a second connector 60, and a third connector 70, and the support includes a fixed base 30 and a support base 40.

[0049] like Figure 7 As shown, in this embodiment, the battery rack 10 is provided with a back plate 11, and fixing plates extend outward in all directions around the back plate 11. Specifically, the battery rack 10 is provided with a first fixing plate 121 and a second fixing plate 122 on its upper and lower sides along the second direction, respectively, to be connected to the support base 40 via connectors. Further, the back plate 11 is provided with a third fixing plate 123 on its left and right sides along the third direction, respectively, to be connected to the fixing base 30 via connectors, thereby ensuring the stable installation of the battery rack 10 on the back side along the first direction.

[0050] like Figure 8As shown, correspondingly, in this embodiment, the battery rack 10 has fixing plates extending outward along the front circumference of the first direction. Specifically, a fourth fixing plate 131 and a fifth fixing plate 132 are respectively provided on the upper and lower sides of the front side of the battery rack 10 along the second direction, so as to be connected to the guide rail assembly 20 through a connecting assembly. Further, a sixth fixing plate 133 is respectively provided on the left and right sides of the front side of the battery rack 10 along the third direction, so as to be connected to the fixing base 30 through a connector, thereby ensuring the stable installation of the battery rack 10 along the front side of the first direction.

[0051] In this embodiment, the first fixing plate 121 and the fourth fixing plate 131 are correspondingly arranged, and there are two of each; the second fixing plate 122 and the fifth fixing plate 132 are correspondingly arranged, and there are two of each. Further, there are two third fixing plates 123, and both third fixing plates 123 are located at the middle position on both sides of the back plate 11 along a third direction. Correspondingly, there are four sixth fixing plates 133, and every two sixth fixing plates 133 are spaced apart on one side of the front side of the battery rack 10 along a third direction. Thus, the back side of the battery rack 10 is fixed to the compartment 100 by two first fixing plates 121, two second fixing plates 122, and two third fixing plates 123, and the front side of the battery rack 10 is fixed to the compartment 100 by two fourth fixing plates 131, two fifth fixing plates 132, and four sixth fixing plates 133.

[0052] Specifically, the battery rack 10 has multiple accommodating spaces 103 for placing battery boxes. Optionally, in this embodiment, four battery racks 10 are provided; in other embodiments, the number can be adjusted as needed, which will not be elaborated here, to meet the placement requirements of the battery boxes and ensure the power supply of the energy storage system. Exemplarily, the battery rack 10 has multiple partitions 14, which are spaced apart and form multiple accommodating spaces 103. In this embodiment, both the partitions 14 and the two side support plates of the battery rack 10 along a third direction have multiple through holes to reduce the weight of the battery rack 10 and ensure ventilation of the battery boxes.

[0053] Furthermore, the battery rack 10 has a first sliding groove 101 and a second sliding groove 102 respectively provided through its upper and lower sides along the second direction along the first direction. Multiple battery racks 10 have corresponding first sliding grooves 101 to form a first slide rail, and multiple battery racks 10 have corresponding second sliding grooves 102 to form a second slide rail. The guide rail assembly 20 is slidably disposed in the first and second slide rails to achieve a sliding connection between the battery rack 10 and the guide rail assembly 20. Optionally, one first sliding groove 101 is provided, located between two first fixing plates 121 and two fourth fixing plates 131; two second sliding grooves 102 are provided, located on the outer sides of two second fixing plates 122 and two fifth fixing plates 132 respectively, to cooperate with the guide rail assembly 20.

[0054] Furthermore, in this embodiment, the cross-section of the battery holder 10 is rectangular. In other embodiments, the cross-sectional shape of the battery holder 10 can also be set as trapezoidal, square, circular, polygonal, or other irregular shapes, which are not limited here. For example, in this embodiment, the battery holder 10 is made of carbon steel. In other embodiments, the material of the battery holder 10 is not limited to aluminum alloy plate, titanium alloy plate, or other high-strength non-metallic materials or composite materials, and can also be made by a combination of materials.

[0055] like Figure 9 As shown, in this embodiment, the guide rail assembly 20 includes a guide rail base 21 and a guide rail 22. The guide rail base 21 can be fixed to the inner wall of the cabin 100, and the guide rail 22 is fixedly disposed on the guide rail base 21, thereby fixing it in the cabin 100. The guide rail 22 extends along a first direction, and the battery rack 10 is slidably disposed on the guide rail 22, thereby realizing that multiple battery racks 10 are sequentially assembled into the cabin 100 along the first direction. Specifically, the guide rail 22 has multiple battery rack fixing positions, and each battery rack 10 can slide along the first direction to the corresponding battery rack fixing position on the guide rail 22 to ensure the stable and accurate installation of each battery rack 10. Exemplarily, in this embodiment, the guide rail assembly 20 is provided in two sets, and the two sets of guide rail assemblies 20 are respectively disposed on the upper and lower inner walls of the cabin 100 along the second direction, located at the top and bottom of the battery rack 10.

[0056] Optionally, the number of guide rails 22 provided on the upper inner wall of the cabin 100 includes, but is not limited to, none or multiple rails, and / or the number of guide rails 22 provided on the lower inner wall of the cabin 100 includes, but is not limited to, none or multiple rails. In this embodiment, the upper inner wall of the cabin 100, that is, the top of the battery rack 10, is provided with one guide rail 22, which corresponds to the first sliding groove 101, so as to realize the stable sliding of the top of the battery rack 10 on the guide rail assembly 20, so as to guide the movement direction of the battery rack 10. Further, the lower inner wall of the cabin 100, that is, the bottom of the battery rack 10, is provided with at least two guide rails 22, which correspond to the two second sliding grooves 102, so as to realize the stable sliding of the bottom of the battery rack 10 on the guide rail assembly 20, thereby improving stability. Specifically, the two bottom guide rails 22 can effectively ensure the stable sliding of the battery rack 10, and together with the top guide rail 22, can guide the sliding direction of the battery rack 10, preventing it from deviating during movement.

[0057] Optionally, in this embodiment, the guide rail base 21 in the guide rail assembly 20 includes multiple crossbeams 211 and multiple longitudinal beams 212, and a cable channel is provided through the guide rail base 21, including a first through channel and a second through channel. Specifically, the crossbeams 211 are arranged along a third direction, and the longitudinal beams 212 are arranged along a first direction, and the two are perpendicular to each other. Specifically, both the crossbeams 211 and the longitudinal beams 212 are fixed to the upper and lower inner walls of the cabin 100 along a second direction to ensure the stable installation of the guide rail 22 and the connection of the battery rack 10.

[0058] For example, a first hole 201 is provided through the crossbeam 211 along a first direction, and the first holes 201 on multiple crossbeams 211 are interconnected to form a first through-channel for passing cables, thereby ensuring that the cables of the battery box on the battery rack 10 can be sequentially passed through to the outside of the compartment 100 along the first direction to organize the cables; and / or, a plurality of second holes 202 are provided through the longitudinal beam 212 along a third direction, and the second holes 202 on multiple longitudinal beams 212 are interconnected to form a second through-channel for passing cables to accommodate different cable arrangement. Optionally, the cross-section of the first hole 201 and the second hole 202 can be set to circular, rectangular, trapezoidal or other shapes, which are not limited here.

[0059] Furthermore, the crossbeam 211 is also provided with a mounting groove 203, and a mounting hole 204 is provided through the bottom of the mounting groove 203. The connecting component is detachably connected to the mounting groove 203 through the mounting hole 204 to ensure a stable connection between the battery rack 10 and the guide rail assembly 20. Furthermore, a guide head 221 is provided at one end of the guide rail 22 away from the inner side of the cabin 100 along the first direction, and the guide head 221 is set with a wedge-shaped structure to guide each battery rack 10 and achieve rapid installation. Exemplarily, in other embodiments, guide rail assemblies 20 can also be provided on the inner walls of the left and right sides of the cabin 100, and the number of guide rails 22 can be set as needed. Correspondingly, the guide rail base 21 can also be provided with a diagonal tie beam, or the guide rail 22 can be directly set on the cabin 100, and the specific method can be set as needed.

[0060] like Figure 10 As shown, in this embodiment, the fixed base 30 includes a frame 31 and multiple support bars 32. Optionally, the frame 31 has connecting holes 301 extending through both sides along the first direction to connect with the third fixing plate 123 and the sixth fixing plate 133 via connectors. Further, the multiple support bars 32 extend along the first direction and are spaced apart within the frame 31 to ensure the mechanical strength of the frame 31. Figure 5 and Figure 6As shown, in this embodiment, each battery rack 10 is provided with two fixed bases 30, and the two fixed bases 30 are located on both sides of the battery rack 10 along a third direction. Specifically, the third fixing plate 123 and the sixth fixing plate 133 are respectively connected to the rear and front sides of the fixed base 30 along the first direction by connectors, thereby ensuring the stable installation of the battery rack 10. Optionally, the connectors on both sides of the battery rack 10 along the third direction are staggered and connected to the fixed base 30, and / or the connectors on both sides of the battery rack 10 along the third direction are integrated with the corresponding fixed base 30 to improve the connection strength. Exemplarily, the position of the fixed base 30 corresponds to the target position of each battery rack 10. Optionally, the fixed base 30 can also be connected by diagonal tie beams.

[0061] Combination Figures 1-4 As shown, in this embodiment, multiple connecting components are provided, each corresponding to a different battery rack fixing position. This allows the battery rack 10, which slides to its corresponding fixing position, to be fixed within the housing 100 via the connecting components, ensuring stable installation of each battery rack 10. Optionally, the support base 40 is fixed to the inner wall of the housing 100, such as... Figure 11 As shown, in this embodiment, the support base 40 includes a base body 41 and a stiffening plate 42. The base body 41 is configured as a portal frame structure, and the stiffening plate 42 is disposed on the inner side of the base body 41 to improve the overall mechanical strength of the support base 40 and prevent deformation during installation. For example, a through hole is provided through the base body 41. Optionally, in this embodiment, the base body 41 is disposed against the crossbeam 211, and the bottom of the base body 41 is fixed to the upper and lower inner walls of the cabin 100. For example, the base body 41 is correspondingly disposed with the first fixing plate 121 and the second fixing plate 122.

[0062] like Figure 12 As shown, specifically, the first connecting member 50 includes a first plate 51 and a second plate 52 arranged in an L-shape, and a reinforcing plate is connected between the two to ensure the connection strength of the first connecting member 50. Further, both the first plate 51 and the second plate 52 are provided with through holes for easy connection. Specifically, the battery rack 10 is fixed to the compartment 100 along both sides of the second direction via the first connecting member 50. Specifically, along the rear side of the battery rack 10 in the first direction, the first fixing plate 121 and the second fixing plate 122 are connected to the support base 40 via the first connecting member 50; along the front side of the battery rack 10 in the first direction, the fourth fixing plate 131 and the fifth fixing plate 132 are connected to the bottom of the mounting groove 203 of the crossbeam 211 via the first connecting member 50, thereby achieving a stable connection between the upper and lower sides of the battery rack 10 and the compartment 100.

[0063] Combination Figure 5 and Figure 6As shown, in this embodiment, the battery rack 10 is fixed to the housing 100 along both sides of the third direction by the second connector 60 and the third connector 70. Specifically, the second connector 60 is used to fix the front side of the battery rack 10 along the first direction, and the third connector 70 is used to fix the rear side of the battery rack 10 along the first direction, thereby providing a stable circumferential connection for the battery rack 10. Specifically, both the second connector 60 and the third connector 70 are detachably connected to the fixed base 30, thereby achieving a stable connection between the battery rack 10 and the fixed base 30. Further, the second connector 60 and the third connector 70 on both sides of the battery rack 10 along the third direction are staggered and connected to the fixed base 30, and / or, the second connector 60 and the third connector 70 on both sides of the battery rack 10 along the third direction are integrated with the corresponding fixed base 30 to form a triangular fixing structure, thereby improving the connection strength.

[0064] Combination Figures 5-8 As shown, in this embodiment, the second connector 60 and the third fixing plate 123 are arranged in a one-to-one correspondence, and the second connector 60 is used to connect the third fixing plate 123 and the fixing base 30 along the back side of the first direction. Further, in this embodiment, the third connector 70 and the sixth fixing plate 133 are arranged in a one-to-one correspondence, and the third connector 70 is used to connect the sixth fixing plate 133 and the fixing base 30 along the front side of the first direction. Thus, the second connector 60 and the third connector 70 can fix the left and right sides of the battery rack 10. Optionally, in other embodiments, the fixing base 30 can be omitted, and the second connector 60 and the third connector 70 can be directly connected to the cabin 100, depending on the specific requirements.

[0065] For example, in this embodiment, the guide rail base 21 and fixed base 30 in the guide rail assembly 20 can be connected to the cabin 100 by welding, screwing or other methods.

[0066] Work process: A battery rack 10 is fabricated using carbon steel structure through welding and other assembly methods to serve as the main body for battery box installation. Then, guide rail bases 21 are pre-arranged and welded inside the cabin 100. Guide rails 22 are installed onto the corresponding guide rail bases 21. Next, fixing bases 30 are pre-arranged and welded inside the cabin 100. Then, the first battery rack 10, which is the rearmost battery rack 10 in the cabin 100, is installed to the corresponding target position. The front and rear sides of the battery rack 10 are fixed with bolts. The battery box is then loaded into the battery rack 10, and the corresponding connecting cables are connected. The first and / or second through-channels are used to guide the battery rack 10 to the front of the housing 100. Then, using specialized equipment, the next battery rack 10 is pushed into the corresponding target position inside the housing 100 via the guide rail 22. The front and rear sides are fixed using specialized extension tools. Then, the cables are connected and passed through the first and / or second through-channels to the front of the housing 100. The above steps are repeated to push all the battery racks 10 in sequence and ensure that all cables are led to the front of the housing 100 to complete the installation of the entire battery pack. Finally, the hatch of the housing 100 is closed.

[0067] On the other hand, the electrical device has a cabin 100 and includes the aforementioned energy storage system, which is located within the cabin 100. In this embodiment, the electrical device, under the action of the guide rail assembly 20, can quickly detach and assemble multiple battery racks 10, enabling the overall pushing and pulling of battery boxes, cables, high-voltage boxes, etc., achieving the overall assembly and disassembly of large-mass battery packs, ensuring load-bearing capacity while facilitating operation by personnel. Specifically, the arrangement of multiple battery racks 10 can improve the space utilization rate inside the cabin 100, effectively reducing the size of the cabin 100, reducing the space occupied by the energy storage system in the hull, and correspondingly reducing weight. At the same time, the energy storage system in this embodiment is applicable to cabins 100 with different cross-sectional shapes, has a wide range of applications, and avoids the need to repair or replace the entire battery pack in a confined space, improving the safety and convenience of personnel operation. Furthermore, by extending or shortening the length of the cabin 100 and changing the number of battery racks 10, the power capacity of the energy storage system can be increased or decreased, making subsequent modification work more convenient.
