Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial and commercial energy storage cabinet packaging technology, specifically to an industrial and commercial energy storage cabinet packaging structure. Background Technology
[0002] In recent years, following the European energy crisis, efforts have been made to reduce reliance on traditional energy sources and vigorously develop renewable energy, leading to a surge in demand for industrial and commercial energy storage systems. The global industrial and commercial energy storage market is projected to exceed 100 GWh by 2025, with a compound annual growth rate (CAGR) of approximately 30%. China's industrial and commercial energy storage capacity is expected to reach 10 GWh by 2025, with an economic inflection point already reached (IRR generally exceeding 8%). However, the volatility of renewable energy poses challenges to the stability of power supply, further highlighting the importance of energy storage. The target enterprises for industrial and commercial energy storage mainly include high-energy-consuming pure electricity companies, wastewater treatment plants, 5G base stations, data center IPC rooms, integrated photovoltaic-storage-charging stations, port shore power, substations, mines, and large industrial enterprises under two-part tariffs. The overseas industrial and commercial energy storage market is showing a dual growth trend driven by both policy and economic viability. Europe and North America remain the core battlegrounds, while Chinese companies are accelerating their overseas expansion due to cost and technological advantages. Future competition will focus on localized services and intelligent solutions.
[0003] Against this backdrop, commercial and industrial energy storage systems exported overseas need to meet certification and compliance requirements. Their packaging and transportation must comply with UN3480 (lithium battery energy storage systems are Class 9 dangerous goods) and the UN's Recommendations on the Transport of Dangerous Goods. Transportation methods include sea, air, and land transport, with sea transport being the most common and relatively cost-effective. Sea transport uses containerized shipping, with the largest container being a 40-foot high cube container. Some energy storage products, due to their large size, may exceed the internal space of a 40-foot high cube container using traditional packaging methods, making it impossible to fit the products inside.
[0004] Therefore, we propose a packaging structure for industrial and commercial energy storage cabinets. Utility Model Content
[0005] The main purpose of this utility model is to provide a packaging structure for industrial and commercial energy storage cabinets. Through a rigid frame composed of a lower pallet, protective crossbeams, and protective longitudinal beams, and a full-wrap design with pearl foam protective covers, it can effectively buffer vibrations and impacts during transportation. After packaging, the overall height is controlled at 2485mm, less than the space limitation of a 40-foot high cube cabinet (internal height 2500mm). Through the adaptable design of the lower pallet and forklift boom slots, mechanized and efficient loading can be achieved, ensuring that each high cube cabinet can maximize space utilization and reduce unit transportation costs; it can effectively solve the problems in the background technology.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0007] A commercial and industrial energy storage cabinet packaging structure includes a cabinet body, an explosion-proof system, an electrical system, a high-voltage box, a battery pack, power cables, an EMS module, a liquid cooling system, a PCS module, lifting rings, fire-fighting components, and a cabinet door. The cabinet body is a vertically arranged rectangular structure. The explosion-proof system is located at the top of the cabinet body. A cabinet door is rotatably connected to one side of the cabinet body. A fire-fighting component is located on the upper part of one side of the cabinet door. Four sets of lifting rings are arranged parallel to each other at the top of the cabinet body. An installation cavity is provided inside the cabinet body. The electrical system, high-voltage box, battery pack, power cables, EMS module, liquid cooling system, and PCS module are all assembled inside the cabinet body.
[0008] The bottom of the cabinet is inserted into the groove of the lower tray. The tray is fixedly connected to the bottom of the cabinet by the first bolt. A pearl foam protective cover is fitted on the outside of the cabinet. The lower part of the outer side of the pearl foam protective cover is connected to the lower tray by a wrapping film. Protective longitudinal beams are fixedly connected to both ends of the top of the lower tray. Protective crossbeams are provided on both sides of the lower part of the pearl foam protective cover. Two sets of protective crossbeams and protective longitudinal beams are arranged relatively parallel to each other. The two sets of protective longitudinal beams are located between the two sets of protective crossbeams.
[0009] By adopting the above technical solution, the rigid frame composed of the lower pallet, protective crossbeams, and protective longitudinal beams can withstand the drop test in UN38.3 standard. The full-wrap design of the pearl foam protective cover can effectively buffer the vibration and impact during transportation. After packaging, the overall height is controlled at 2485mm, which is less than the space limitation of a 40-foot high cube container (internal height 2500mm). This solves the problem that energy storage cabinets cannot be loaded into containers due to excessive height under traditional packaging methods. At the same time, the adaptable design of the lower pallet and forklift boom slot can realize mechanized and efficient loading, ensuring that the space of a single 40-foot high cube container can be maximized and reducing the unit transportation cost.
[0010] Specifically, both ends of the protective longitudinal beam are fixedly connected to the inner walls of both sides of the protective transverse beam, and the two sets of protective transverse beams and protective longitudinal beams together form a rectangular frame structure fitted under the pearl foam protective cover.
[0011] Specifically, the top of the pearl foam protective cover is provided with a through hole for the hanging ring to pass through, and four sets of through holes are arranged in parallel.
[0012] Specifically, a forklift arm groove is provided between the bottom of the cabinet and the lower pallet.
[0013] Specifically, the lower tray has multiple operating openings at its bottom.
[0014] The beneficial effects of this utility model are as follows: The industrial and commercial energy storage cabinet packaging structure described in this utility model, through the rigid frame composed of the lower pallet, protective crossbeams, and protective longitudinal beams, can withstand the drop test in the UN38.3 standard. Through the full-wrap design of the pearl foam protective cover, it can effectively buffer the vibration and impact during transportation. After packaging, the overall height is controlled at 2485mm, which is less than the space limitation of a 40-foot high cube container (internal height 2500mm). This solves the problem that energy storage cabinets cannot be loaded into containers due to exceeding the height limit under traditional packaging methods. At the same time, the adaptable design of the lower pallet and the forklift boom slot can realize mechanized and efficient loading, ensuring that the space utilization of a single 40-foot high cube container can be maximized and reducing the unit transportation cost.
[0015] The rectangular frame structure at the bottom rigidly connects the cabinet to the lower pallet, so that the forklift forks only contact the frame during forklift operation, avoiding direct pressure on the bottom of the cabinet; while the pearl foam protective cover does not affect the lifting function of the lifting rings, and can protect the exposed components such as the explosion-proof system and EMS module at the top of the cabinet; this composite protection mode of "rigid frame + flexible buffer" can reduce the transportation loss rate to below 0.5% while ensuring loading and unloading efficiency.
[0016] Whether it's sea, land, or air transport, this structure can adapt to the intensity of bumps in different modes of transportation by adjusting the wrapping density of the stretch film and the strength of the frame connectors. For example, high-frequency, small-amplitude vibrations encountered during sea transport can be absorbed by the pearl foam, while the impact of sudden braking during land transport is offset by the rigid frame, ensuring that the energy storage cabinet remains intact in the transportation links of various regions around the world.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0025] As one embodiment of this utility model, such as Figures 1-5 As shown, the packaging structure of the industrial and commercial energy storage cabinet of this utility model includes a cabinet body 1, an explosion-proof system 2, an electrical system 3, a high-voltage box 4, a battery pack 5, a power cable 6, an EMS module 7, a liquid cooling system 8, a PCS module 9, lifting rings 10, fire-fighting components 11, and a cabinet door 12. The cabinet body 1 is a vertically arranged rectangular structure. The explosion-proof system 2 is provided at the top of the cabinet body 1. The cabinet door 12 is rotatably connected to one side of the cabinet body 1. The fire-fighting components 11 are provided on the upper part of one side of the cabinet door 12. Four sets of lifting rings 10 are arranged parallel to each other at the top of the cabinet body 1. The cabinet body 1 has an installation cavity inside. The electrical system 3, the high-voltage box 4, the battery pack 5, the power cable 6, the EMS module 7, the liquid cooling system 8, and the PCS module 9 are all assembled inside the cabinet body 1.
[0026] The bottom end of the cabinet 1 is inserted into the groove 17 of the lower tray 14. The tray 14 is fixedly connected to the bottom end of the cabinet 1 by the first bolt 13. A pearl foam protective cover 15 is fitted on the outside of the cabinet 1. The lower part of the outer side of the pearl foam protective cover 15 is connected to the lower tray 14 by a wrapping film. Protective longitudinal beams 20 are fixedly connected to both ends of the top of the lower tray 14. Protective crossbeams 19 are provided on both sides of the lower part of the pearl foam protective cover 15. Two sets of protective crossbeams 19 and protective longitudinal beams 20 are arranged relatively parallel to each other. The two sets of protective longitudinal beams 20 are located between the two sets of protective crossbeams 19.
[0027] In use, firstly, precisely align the bottom of the cabinet 1 of the industrial and commercial energy storage cabinet with the lower pallet 14. The bottom of the cabinet 1 is rigidly connected to the lower pallet 14 by four sets of first bolts 13, ensuring that the cabinet 1 will not undergo longitudinal displacement during transportation. Multiple pre-set operating openings 18 at the bottom of the lower pallet 14 facilitate the operator to tighten the first bolts 13 from the bottom, improving installation efficiency. After the cabinet 1 and the lower pallet 14 are fixed, assemble two sets of protective crossbeams 19 and two sets of protective longitudinal beams 20 into a rectangular frame structure. The two ends of the protective longitudinal beams 20 are fixed to the inner walls of the two sides of the protective crossbeams 19 by mortise and tenon structures or metal connectors, forming a frame that fits onto the outside of the bottom of the cabinet 1 and is connected to the pre-set interface at the top of the lower pallet 14 by second bolts. This frame structure can directly bear part of the weight of the cabinet 1, preventing the fork arms from directly contacting the cabinet 1 during forklift operation and effectively preventing the bottom of the cabinet 1 from deforming due to external impact.
[0028] This utility model also includes that both ends of the protective longitudinal beam 20 are fixedly connected to the inner walls of both sides of the protective cross beam 19, and the two sets of the protective cross beam 19 and the protective longitudinal beam 20 together form a rectangular frame structure fitted under the pearl foam protective cover 15.
[0029] This utility model also includes a through hole at the top of the pearl foam protective cover 15 for the hanging ring 10 to pass through, and four sets of through holes are arranged in parallel.
[0030] The present invention also includes a forklift arm groove 16 provided between the bottom end of the cabinet 1 and the lower pallet 14.
[0031] The present invention also includes that the bottom end of the lower tray 14 is provided with an operation opening 18, and the operation opening 18 is provided in multiple ways.
[0032] When using this utility model, the packaging structure of the industrial and commercial energy storage cabinet must follow these steps during actual assembly and use to ensure compliance with UN3480 dangerous goods transport standards and maritime container loading requirements:
[0033] Basic fixing operation: First, precisely align the bottom of the cabinet 1 of the industrial and commercial energy storage cabinet with the lower tray 14.
