Description

Technical Field

[0001] This invention relates to the field of power equipment technology, and in particular to a dustproof and waterproof structure for an integrated energy storage unit. Background Technology

[0002] With the rapid development of the new energy industry, integrated energy storage units, as core equipment for energy storage and management, are increasingly widely used in residential energy storage, industrial and commercial energy storage, and off-grid power supply scenarios. These devices typically need to operate for extended periods in outdoor or industrial environments, facing the corrosive effects of complex environmental factors such as dust, rain, and salt spray, which places stringent requirements on the equipment's protective performance.

[0003] Currently, the protective structure of traditional integrated energy storage devices mainly suffers from the following problems: 1) The contradiction between dustproof and waterproof and heat dissipation: In order to meet the IP54 / IP65 protection level, the equipment often adopts a highly sealed enclosure design. However, excessive sealing will hinder the dissipation of internal heat, resulting in excessive temperature rise of the equipment, which will affect battery life and system stability.

[0004] 2) Insufficient ease of maintenance: Conventional protective structures (such as multi-layer sealing strips and screw-fastened covers) require cumbersome disassembly when the equipment needs maintenance or component replacement, which can easily damage the seals, and it is difficult to guarantee the original protective performance after reassembly. In addition, the dust filter at the air inlet is easily clogged by dust and requires frequent cleaning, but existing designs often require the removal of multiple screws or the removal of the entire panel, resulting in low maintenance efficiency. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a dustproof and waterproof structure for an integrated energy storage unit that has good dustproof and waterproof effect, can balance heat dissipation and protection, and has low maintenance and consumable costs.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A dustproof and waterproof structure for an integrated energy storage device includes louvers, a first dust cover on the inner side of the louvers, a second dust cover on the inner side of the first dust cover, a first filter element inside the first dust cover, a second filter element inside the second dust cover, and a buffer layer formed between the first dust cover and the second dust cover.

[0007] As a further improvement to the above technical solution: The louver includes a window frame and multiple louver blades arranged vertically at intervals within the window frame. Each louver blade has an S-shaped cross-section, and a maze-like passage is formed between adjacent louver blades.

[0008] The bottom of the window frame is provided with a drain hole.

[0009] The first dust cover includes a first frame and a first mesh plate disposed on the first frame, the first mesh plate being used to press the first filter element onto the louver blades.

[0010] The bottom of the first frame is provided with a folded edge, and the window frame is provided with a slot for engaging with the folded edge.

[0011] The second dust cover includes a second frame, and a second mesh plate and a third mesh plate disposed on the second frame, with the second filter element disposed between the second mesh plate and the third mesh plate.

[0012] The first filter element is urethane black cotton, and the second filter element is G3 filter cotton.

[0013] The thickness of the buffer layer is 10mm-50mm.

[0014] The window frame is installed on the outside of the cabinet of the energy storage unit via hinges. The first dust cover is detachably connected to the window frame, and the second dust cover is fixedly connected to the inside of the cabinet.

[0015] The first dust cover is detachably connected to the window frame by bolts.

[0016] Compared with the prior art, the advantages of the present invention are as follows: 1. The dustproof and waterproof structure of the energy storage unit of the present invention, through the synergistic design of gradient filtration and sedimentation buffer, adopts a four-level protection of "louvers + first filter + buffer layer + second filter" which is not completely sealed, and achieves efficient treatment of dust and rainwater step by step, with good dustproof and waterproof effect. The buffer layer not only reduces the dust flow rate, but also forms part of the ventilation channel, effectively balancing heat dissipation and protection. Under the premise of meeting the same protection level, it ensures smooth ventilation and heat dissipation, solves the pain point of excessive equipment temperature rise, and ensures system stability and device life. Furthermore, due to the reduction and sedimentation of dust by the buffer layer, the filtration burden of the second filter can be reduced, the cleaning and maintenance cycle of the second filter can be extended, and maintenance and consumable costs can be reduced.

[0017] 2. The dustproof and waterproof structure of the energy storage unit of the present invention, by setting S-shaped louvers and forming a labyrinthine channel between adjacent louvers, can block and settle large dust particles and most rainwater, preventing them from entering the inside of the louvers, thus initially achieving waterproof and dustproof protection, while not obstructing air circulation and ensuring heat dissipation.

[0018] 3. The dustproof and waterproof structure of the energy storage unit of the present invention, although the louvers block most of the rainwater, still allows some rainwater to flow into the inside of the louvers. After being absorbed by the first filter element, the rainwater absorbed by the first filter element can be discharged from the cabinet by setting a drain hole at the bottom of the window frame, thus preventing water from seeping into the cabinet. This makes the overall structure more reliable and stable in terms of waterproof performance while ensuring high dustproof efficiency.

[0019] 4. The dustproof and waterproof structure of the energy storage unit of the present invention allows for easy maintenance and replacement of the first filter element when maintenance, cleaning, or filter replacement is required. Simply rotate the louvers to the maintenance angle, remove the first dust cover, and the first filter element in the first dust cover can be maintained or replaced without completely removing the protective structure. The disassembly and assembly steps are simple and the maintenance is convenient. Attached Figure Description

Detailed Implementation

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In the description of this invention, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, 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. Therefore, they should not be construed as limitations on this invention.

[0031] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] In this invention, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "joining," and "fixing," etc., should be interpreted broadly. 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 this invention according to the specific circumstances.

[0033] like Figures 1 to 8 As shown, the dustproof and waterproof structure of the energy storage integrated machine in this embodiment includes a louver 1, a first dust cover 2 is provided on the inner side of the louver 1, a second dust cover 3 is provided on the inner side of the first dust cover 2, a first filter element 5 is provided inside the first dust cover 2, a second filter element 6 is provided inside the second dust cover 3, and a buffer layer 4 is formed between the first dust cover 2 and the second dust cover 3.

[0034] The dustproof and waterproof structure of the energy storage unit in this embodiment utilizes a gradient filtration and sedimentation buffer design. It employs a four-level protection system—"louvers 1 + first filter element 5 + buffer layer 4 + second filter element 6"—that is not completely sealed. This achieves efficient, step-by-step treatment of dust and rainwater, resulting in excellent dustproof and waterproof performance. The buffer layer 4 not only reduces dust flow velocity but also forms part of the ventilation channel, effectively balancing heat dissipation and protection. While meeting the required protection level, it ensures smooth ventilation and heat dissipation, resolving the issue of excessive equipment temperature rise and guaranteeing system stability and component lifespan. Furthermore, the buffer layer 4's reduction and sedimentation of dust alleviates the filtration burden on the second filter element 6, extending its cleaning and maintenance cycle and reducing maintenance and consumable costs.

[0035] Furthermore, in this embodiment, the louver 1 includes a window frame 11 and a plurality of louver blades 12 arranged vertically at intervals within the window frame 11. The cross-section of the louver blades 12 is S-shaped, and a maze-like channel 13 is formed between adjacent louver blades 12. By setting the S-shaped louver blades 12 and forming a maze-like channel 13 between adjacent louver blades 12, large dust particles and most rainwater can be blocked and settled, preventing them from entering the inside of the louver 1, thus initially achieving waterproofing and dustproofing, while not obstructing air circulation and ensuring heat dissipation.

[0036] Furthermore, in this embodiment, a drain hole 114 is provided at the bottom of the window frame 11. Although the louver 1 blocks most of the rainwater, some rainwater still flows into the inside of the louver 1 and is absorbed by the first filter element 5. By providing a drain hole 114 at the bottom of the window frame 11, the rainwater absorbed by the first filter element 5 can be discharged from the cabinet, preventing water from seeping into the cabinet. This ensures that the overall structure maintains high dustproof efficiency while making its waterproof performance more reliable and stable.

[0037] Preferably, in this embodiment, three drainage holes 11 with a diameter of 5mm are evenly opened at the bottom of the outer maintenance louver 1 to facilitate the rapid flow of rainwater.

[0038] Furthermore, in this embodiment, the first dust cover 2 includes a first frame 21 and a first mesh plate 22 disposed on the first frame 21. The first mesh plate 22 is used to press the first filter element 5 onto the louver blades 12. The first mesh plate 22 can provide stable support for the first filter element 5, preventing the first filter element 5 from shifting under wind pressure, ensuring the stability of the filter structure. At the same time, the mesh structure will not obstruct the normal airflow and will not affect the heat dissipation effect.

[0039] Furthermore, the bottom of the first frame 21 is provided with a folded edge 211, and the window frame 11 is provided with a slot 111 for engaging with the folded edge 211. During installation, simply insert the folded edge 211 at the bottom of the first frame 21 into the slot 111 to complete the initial positioning of the first dust cover 2, and then tighten it with bolts 7 to complete the fixation. The installation and removal are convenient, and it is easy to clean and maintain the first dust cover 2 and the first filter element 5.

[0040] Furthermore, in this embodiment, the second dust cover 3 includes a second frame 31, and a second mesh plate 32 and a third mesh plate 33 disposed on the second frame 31, with the second filter element 6 disposed between the second mesh plate 32 and the third mesh plate 33. This clamping and fixing structure ensures that the position of the second filter element 6 is stable and will not shift due to airflow, thus ensuring the continuity of the filtration effect.

[0041] Furthermore, in this embodiment, the first filter element 5 is urethane black cotton, and the second filter element 6 is G3 filter cotton. The urethane black cotton has large pores, which can initially filter dust and adsorb condensed water vapor, while the G3 filter cotton can further filter fine dust after buffering and settling. The two-stage filtration works together to ensure the dust prevention effect while avoiding the filter elements from clogging too quickly and extending the maintenance cycle.

[0042] Preferably, in this embodiment, the thickness of the buffer layer 4 (i.e., the distance between the second dust cover 3 and the first dust cover 2) is 40mm. Of course, in other embodiments, the thickness of the buffer layer 4 can be adjusted according to the requirements of cabinet ventilation, dustproof level, etc., to meet the usage requirements of different application scenarios.

[0043] Furthermore, in this embodiment, the window frame 11 is hinged to the outside of the energy storage unit's cabinet. The first dust cover 2 is detachably connected to the window frame 11 (specifically, the first frame 21 is detachably connected to the window frame 11), and the second dust cover 3 is fixedly connected to the inside of the cabinet (specifically, the second frame 31 is fixedly connected to the inside of the cabinet). When maintenance, cleaning, or filter replacement is required, the louver 1 is rotated open to the maintenance angle, and the first dust cover 2 is removed. The first filter 5 in the first dust cover 2 can then be maintained or replaced without completely removing the protective structure. The disassembly and assembly steps are simple, and maintenance is highly convenient.

[0044] Preferably, in this embodiment, the second mesh plate 32 is located on the outside of the second frame 31, and the third mesh plate 33 is located on the inside of the second frame 31. The second mesh plate 32 is detachably connected to the second frame 31. When the louver 1 is rotated open to the maintenance angle, the second mesh plate 32 can be removed to maintain and replace the second filter element 6 in the second dust cover 3 without removing the second frame 31 and the third mesh plate 33, further improving maintenance convenience.

[0045] Furthermore, in this embodiment, the first dust cover 2 is detachably connected to the window frame 11 by bolts 7. Specifically, the first frame 21 is detachably connected to the window frame 11 by bolts. By rotating and opening the louver 1, and loosening the bolts fixing the first frame 21, the first dust cover 2 can be removed as a whole, which is simple to operate.
