Description

Technical Field

[0001] This invention relates to the field of energy storage system technology, and in particular to an energy storage container. Background Technology

[0002] As ship energy systems upgrade towards cleaner and more efficient systems, marine containerized energy storage systems have become core equipment for ensuring stable power supply and adapting to new energy sources, with energy storage containers being a key component. Due to the enclosed environment and dense concentration of personnel and equipment on ships, fires in energy storage containers can easily lead to serious safety accidents. Therefore, the industry has clearly required that they meet the fire resistance protection standards for fiber-based fire temperature rise curves for a specified duration to allow time for emergency response.

[0003] Unlike standard shipping containers, marine energy storage containers have numerous internal columns, beams, and other supporting structures to meet load-bearing and internal equipment installation requirements, forming a non-standard frame. Current fire-resistant designs mostly use conventional fire-resistant materials to cover the container body, relying on the material's own thermal insulation properties to block the transfer of flames and heat, thereby achieving fire resistance.

[0004] However, at the joints where various beams (beams, columns, etc.) inside the existing containers are connected, thermal bridges are easily formed, which makes it difficult for the overall fire resistance performance of energy storage containers to meet the prescribed standards and thus fails to meet the safety requirements of energy storage containers.

[0005] Therefore, the above problems urgently need to be solved. Summary of the Invention

[0006] The purpose of this invention is to provide an energy storage container that blocks heat transfer channels and eliminates the formation path of thermal bridges, thereby enabling the overall fire resistance of the energy storage container to meet the prescribed standards and thus satisfy the safety requirements of the energy storage container.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] An energy storage container includes a main frame, a supporting structure, a covering component, and a thermal insulation component, wherein:

[0009] A receiving cavity is formed within the main frame;

[0010] The cover is wrapped around the outer periphery of the main frame to close the receiving cavity;

[0011] The supporting structure is located inside the receiving cavity and connected to the main frame to enhance the overall structural strength of the energy storage container and to divide the receiving cavity into multiple partitioned cavities, each of which is used to place different energy storage devices.

[0012] The main frame includes multiple first connection nodes formed by the connection of its own components;

[0013] A second connection node is formed at the junction of the supporting structure and the main frame;

[0014] The heat insulation component is provided for all the first connection nodes and the second connection nodes, and is respectively covered on the outside of all the first connection nodes and the second connection nodes.

[0015] Preferably, the heat insulation element is filled between the cover and the main frame.

[0016] Preferably, the main frame includes a plurality of main beams and a plurality of reinforcing beams, wherein:

[0017] Several main beams are interconnected and enclose each other to form the outline frame of each side of the main frame;

[0018] Several of the reinforcing beams are respectively connected between adjacent main beams.

[0019] Preferably, a preset distance is left between the connection position of each reinforcing beam and the main beam and the side of the main beam facing the cover, so that a heat insulation cavity is formed between each reinforcing beam and the cover.

[0020] Preferably, the heat insulation cavity is filled with the heat insulation component.

[0021] Preferably, at least one side of the main frame has an opening;

[0022] The energy storage container also includes a fire door movably connected to the main frame, the fire door being used to close the opening or leave the opening open.

[0023] Preferably, the fire door frame is a hollow structure, and the heat insulation component is embedded inside the hollow part of the door frame.

[0024] Preferably, the support structure includes a plurality of support beams, each of which is arranged at intervals along the length or width of the receiving cavity to divide the receiving cavity.

[0025] Preferably, both ends of each of the supporting beams are fixedly connected to the reinforcing beams or the main beams on opposite sides.

[0026] Preferably, the heat insulation component is rock wool.

[0027] The beneficial effects of this invention are:

[0028] The energy storage container provided by the present invention uses heat insulation components to cover the first and second connecting nodes, which can fit the structure of the first and second connecting nodes to achieve tight protection, thereby blocking the heat transfer channel and eliminating the formation path of thermal bridges. This allows the overall fire resistance of the energy storage container to meet the specified standards, and thus meets the safety requirements of the energy storage container.

[0035] The invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the drawings, not the entire structure.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the invention based on the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0039] Please see Figures 1 to 4 This embodiment provides an energy storage container, including a main frame 1, a support structure 2, a cover 3, and a heat insulation component 4. A receiving cavity 11 is formed within the main frame 1. The cover 3 covers the outer periphery of the main frame 1 to close the receiving cavity 11. The support structure 2 is disposed within the receiving cavity 11 and connected to the main frame 1 to enhance the overall structural strength of the energy storage container and divide the receiving cavity 11 into multiple partitioned cavities, each used to house different energy storage devices. The main frame 1 includes multiple first connection nodes 5 formed by the connection of its own components. Second connection nodes 6 are formed at the connection between the support structure 2 and the main frame 1. The heat insulation component 4 is disposed corresponding to all first connection nodes 5 and second connection nodes 6, and respectively covers the outer side of all first connection nodes 5 and second connection nodes 6.

[0040] It should be noted that the first connection node 5 and the second connection node 6 mentioned above correspond exactly to the locations in existing energy storage containers where thermal bridges are easily formed. That is, they are all junctions of different components, which are equivalent to the key locations in traditional structures where thermal bridges are easily formed.

[0041] It is understandable that by using heat insulation component 4 to cover the first connection node 5 and the second connection node 6, the structure of the first connection node 5 and the second connection node 6 can be closely fitted to achieve tight protection, thereby blocking the heat transfer channel and eliminating the formation path of thermal bridge. This allows the overall fire resistance of the energy storage container to meet the prescribed standards, and thus meets the safety requirements of the energy storage container.

[0042] In this embodiment, the insulation component 4 is rock wool. Rock wool is a widely used fireproof material in the prior art. There is no need to develop new materials or complex construction processes. Its structure is simple, easy to cut and lay, and it also has good fit and plasticity, which can adapt to complex structures, reduce construction difficulty, and control material and construction costs.

[0043] To further enhance the overall fire resistance of the energy storage container, a heat insulation component 4 is filled between the cover 3 and the main frame 1. This arrangement fills the gap between the cover 3 and the main frame 1, further strengthening the overall fire resistance of the energy storage container. Simultaneously, leveraging the plasticity of rock wool, it can adapt to irregular shapes in the gap between the cover 3 and the main frame 1, achieving reliable protection without complex construction, thus balancing practical needs and economy.

[0044] Generally, ships face continuous dynamic loads such as turbulence, rolling, and wave impact during navigation. The navigation environment is enclosed, with dense equipment and personnel, requiring the main frame 1 to withstand long-term alternating external forces without deformation or structural damage. Simultaneously, the energy storage container needs to carry a large number of energy storage devices, and the concentrated weight of these devices creates a continuous static load on the main frame 1. Furthermore, the assembly and fixation of fire-resistant structures (such as insulation components 4 and covering components 3) also rely on the structurally stable main frame 1. In addition, the energy storage container must withstand concentrated external forces during hoisting, relocation, and long-term fixation on the ship. These combined characteristics of multiple application scenarios necessitate that the main frame 1 possess higher overall rigidity, deformation resistance, and load distribution capabilities to ensure equipment safety, structural stability, and reliable fire resistance.

[0045] Therefore, in this embodiment, the main frame 1 includes several main beams 12 and several reinforcing beams 13. The main beams 12 are interconnected and enclose each other to form the outline frame of each side of the main frame 1. The reinforcing beams 13 are respectively connected between adjacent main beams 12. This arrangement can form a stable basic load-bearing structure, effectively dispersing the weight of the internal energy storage equipment and the external forces during ship navigation, ensuring the overall rigidity and deformation resistance of the main frame 1, and meeting the strength requirements of marine applications; it can also allow the cover 3 to fit and cover precisely with the regular outline, and the auxiliary support formed by the reinforcing beams 13 can fix the installation position of the heat insulation component 4, providing a stable foundation for the assembly of the heat insulation component 4 and the cover 3, and ensuring the continuity of the heat insulation structure; it can also serve as a reliable installation benchmark for the support structure 2, ensuring the accurate position of the partition cavity to meet the placement requirements of different energy storage devices.

[0046] Furthermore, a predetermined distance is left between the connection points of each reinforcing beam 13 and the main beam 12 and the side of the main beam 12 facing the cover 3, so that a heat insulation cavity is formed between each reinforcing beam 13 and the cover 3. The heat insulation cavity can form a buffer space between the reinforcing beam 13 and the cover 3, and the buffer space can increase the resistance to heat transfer and further block the thermal bridging effect.

[0047] Furthermore, the insulation cavity serves as a receiving area for the insulation component 4, allowing it to fit more closely between the reinforcing beam 13 and the cover 3. This prevents the insulation component 4 from failing to fully fill the gaps due to the reinforcing beam 13 directly contacting the cover 3. Simultaneously, the cavity formed by the pre-set spacing reduces the pressure on the insulation component 4 caused by vibrations during ship navigation, preventing displacement, maintaining the integrity of the insulation component 4, and ensuring the continuity and stability of the insulation structure.

[0048] Correspondingly, the insulation cavity is filled with insulation component 4. After filling the insulation cavity with insulation component 4, the heat conduction path can be further cut off, thereby improving the overall heat insulation and protection effect.

[0049] To balance the practical needs of loading, unloading, and maintaining energy storage equipment with the overall fireproof sealing of the container, at least one side of the main frame 1 has an opening. The energy storage container also includes a fire door 7 movably connected to the main frame 1. The fire door 7 is used to close the opening or leave it open. It is understandable that energy storage containers require regular equipment inspection and maintenance, and initial equipment installation needs to be convenient for operation. The opening solves the inconvenience of loading, unloading, and maintenance caused by a closed container. The fire door 7 uses a movable connection, allowing for flexible switching between open and closed states. When open, it does not obstruct equipment entry or personnel operation; when closed, it fits snugly against the main frame 1, without affecting the overall structural stability of the container.

[0050] It should be noted that the movable connection between the fire door 7 and the main frame 1 can be achieved using existing technology, specifically common methods such as hinge connection or chain connection. Furthermore, the specific model of the fire door 7 can be selected according to relevant ship fire protection standards; this embodiment does not impose specific requirements or limitations.

[0051] Specifically, the door frame of the fire door 7 has a hollow structure, with a heat insulation component 4 embedded inside. The door frame of the fire door 7 is mostly made of metal, which has high thermal conductivity. Without insulation, it can easily become a channel for rapid heat conduction, creating new thermal bridges at the junctions of the door frame, the main frame 1, and the door leaf of the fire door 7. Therefore, the hollow structure of the door frame with the embedded heat insulation component 4 can utilize its insulation properties to cut off the heat conduction path of the metal door frame, preventing heat from penetrating through the door frame into the interior or exterior of the enclosure, thus ensuring the integrity of the fire-resistant structure.

[0052] Specifically, the support structure 2 includes several support beams 21, which are spaced apart along the length or width of the receiving cavity 11 to divide the receiving cavity 11. This arrangement allows for flexible adjustment of the spacing according to the size and number of energy storage devices, creating partitioned cavities with uniform or differentiated specifications. This precisely matches the installation space requirements of different energy storage devices, avoids the problem of poor equipment compatibility caused by a single cavity, and improves the utilization rate of the enclosure space.

[0053] In addition, several support beams 21 are spaced apart and cooperate with the main beams 12 and reinforcing beams 13 of the main frame 1, which can further disperse the overall load, avoid local stress concentration, reduce the deformation of the energy storage container caused by long-term stress or dynamic impact, and ensure the long-term structural stability of the energy storage container.

[0054] Furthermore, both ends of each support beam 21 are fixedly connected to the reinforcing beams 13 or main beams 12 on the opposite sides. As can be seen, each support beam 21 is fixed only to the reinforcing beams 13 or main beams 12 at both ends; there is no direct connection between the support beams 21, and no additional connecting structure exists, thus eliminating the possibility of new thermal bridges arising from the interconnection of the support beams 21. Simultaneously, the direct fixation of both ends of the support beams 21 to the main beams 12 or reinforcing beams 13 of the main frame 1 allows the weight of the equipment and dynamic impact loads borne by the support beams 21 to be transferred to the main frame 1. This ensures that the load is evenly distributed throughout the main frame 1, preventing deformation or breakage caused by concentrated stress on the support beams 21, significantly improving the overall load-bearing stability and deformation resistance of the enclosure, and making it suitable for complex marine environments.

[0055] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. 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 the present invention should be included within the scope of protection of the claims of the present invention.
