Description

Technical Field

[0001] This utility model relates to the field of building materials technology for new energy storage power stations, specifically to an aluminum profile aluminum honeycomb composite panel. Background Technology

[0002] As core energy storage facilities, new energy energy storage power stations have extremely high requirements for the safety (fire resistance, electromagnetic interference prevention), durability (corrosion resistance, wear resistance, aging resistance), and structural stability of building materials. While existing aluminum honeycomb composite panels are lightweight, they have the following shortcomings when used in the special environment of energy storage power stations:

[0003] 1. Insufficient fire resistance, making it difficult to cope with the potential high temperatures or open flames in the battery compartment;

[0004] 2. Lack of targeted electromagnetic shielding design, making it susceptible to interference from external electromagnetic signals;

[0005] 3. The connection structure has low installation efficiency and is prone to loosening due to vibration after long-term use;

[0006] 4. Insufficient compatibility between thermal insulation and sound insulation performance, failing to meet the constant temperature and low noise requirements of energy storage power stations. Utility Model Content

[0007] (a) Technical problems to be solved

[0008] To address the shortcomings of existing technologies, this utility model provides an aluminum profile aluminum honeycomb composite panel that achieves high safety, strong stability, high environmental adaptability, long service life, and ease of use. It solves the problems of poor fire resistance, insufficient electromagnetic shielding, low connection reliability, and weak performance adaptability that exist during use.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0011] An aluminum profile aluminum honeycomb composite panel includes an aluminum honeycomb core and a composite panel formed by combining surface aluminum profile panels disposed on both sides, wherein the surface aluminum profile panels are fixedly connected to the frame by connecting components.

[0012] The connection assembly between the surface aluminum profile plate and the frame includes a connecting lug plate and rivets. The rivets pass through the rivet holes opened at corresponding positions on the surface aluminum profile plate and the rivet holes on the connecting lug plate to fix the surface aluminum profile plate and the connecting lug plate, which can make the connection more secure, prevent loosening, and improve the connection strength.

[0013] The aluminum honeycomb core is placed in the cavity formed between the surface aluminum profile plate and the frame;

[0014] The surface of the aluminum profile plate that contacts the aluminum honeycomb core, as well as the surface of the aluminum honeycomb core, are coated with an anti-corrosion coating, which is an epoxy zinc-rich coating with a thickness of 0.05-0.1mm. This coating can improve the corrosion resistance of the composite plate and extend its service life.

[0015] The surface aluminum profile plate has a wear-resistant layer on the outer side of the composite plate. The wear-resistant layer is an aluminum oxide coating, which gives the composite plate good anti-corrosion and wear-resistant properties and extends its service life.

[0016] The aluminum honeycomb core is filled with sound-insulating cotton, which can significantly improve the sound insulation performance of the composite board. The aluminum honeycomb core and the surface aluminum profile are fixed and bonded together with glue, which improves the structural stability of the entire board.

[0017] The honeycomb cells are in the shape of regular hexagons. The regular hexagonal structure allows the aluminum honeycomb core to be more uniform when subjected to pressure, thereby improving the overall strength of the composite panel.

[0018] It also includes a reinforcing skeleton embedded in the aluminum honeycomb core;

[0019] The reinforcing skeleton is arranged in a cross shape, and the height of the reinforcing skeleton is adapted to the thickness of the aluminum honeycomb core.

The built-in reinforcing skeleton enhances the impact resistance of the plate, preventing damage from outdoor impacts and bumps. The gradient pore size of the aluminum honeycomb core, combined with the composite filler, provides heat insulation and sound insulation, adapting to the constant temperature and low noise environment of energy storage power stations.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, one embodiment of this utility model proposes an aluminum profile aluminum honeycomb composite panel, which includes an aluminum honeycomb core 103 and a surface aluminum profile plate 101 disposed on both sides to form a composite panel body 1, wherein the surface aluminum profile plate 101 is fixedly connected to the frame 102 by a connecting component.

[0031] The connecting assembly between the surface aluminum profile 101 and the frame 102 includes a connecting ear plate 1021 and rivets. The rivets pass through the rivet holes opened at corresponding positions on the surface aluminum profile 101 and the rivet holes on the connecting ear plate 1021 to fix the surface aluminum profile 101 and the connecting ear plate 1021 together. This makes the connection more secure, prevents loosening, improves the connection strength, and uses sealing strips to fill the gaps to prevent water seepage at the rivet joint.

[0032] Among them, the connecting ear plate 1021 is made of tin-plated steel plate with a tin layer thickness of ≥5μm, which improves both conductivity and corrosion resistance. The connecting rivets used are made of copper, and epoxy conductive adhesive is applied to the inner wall of the rivet hole with a volume resistivity of ≤0.01Ω·cm. After riveting, the conductive adhesive fills the gap between the rivet and the hole wall, ensuring the conductive connection between the surface aluminum profile plate 101, the connecting ear plate 1021, and the copper rivet, eliminating the "shielding breakpoint" at the connection point.

[0033] Meanwhile, a "U-shaped groove" is made at the contact point between the edge of the frame 102 and the edge of the surface aluminum profile plate 101. Nickel-plated copper wire conductive foam is embedded in the groove. The foam diameter is 2-3mm and the compression is 30%-50%. When splicing, adjacent frames 102 are connected by copper bolts. Conductive paste is applied to the threads of the copper bolts. The contact resistance is ≤5mΩ. This ensures that the conductive foam is tightly attached after splicing, forming a continuous conductive path and blocking electromagnetic waves from leaking / invading from the splicing seam.

[0034] The frame 102 adopts a composite structure of aluminum-magnesium alloy and conductive rubber layer. The conductive rubber layer is 0.5-1mm thick and is made of silver powder-filled silicone rubber with a volume resistivity of ≤0.005Ω·cm. This ensures tight conductive contact between the frame 102 and the surface aluminum profile plate 101 and the high-purity copper mesh, avoiding shielding failure caused by gaps. A high-purity copper mesh with a mesh diameter of ≤0.1mm is embedded inside the surface aluminum profile plate 101. The edge of the high-purity copper mesh is double-fixed to the inside of the surface aluminum profile plate 101 by "conductive rivets + conductive adhesive", avoiding shielding gaps caused by loosening of the high-purity copper mesh. A closed shielding circuit is formed through the conductive rubber layer of the frame 102.

[0035] The aluminum honeycomb core 103 is placed in the cavity formed between the surface aluminum profile plate 101 and the frame 102;

[0036] The surface of the aluminum profile plate 101 in contact with the aluminum honeycomb core 103 and the surface of the aluminum honeycomb core 103 are coated with an anti-corrosion coating, which is an epoxy zinc-rich coating with a thickness of 0.05-0.1mm. This coating can improve the corrosion resistance of the composite plate 1 and extend its service life.

[0037] Among them, a fireproof and heat-insulating coating is also provided between the anti-corrosion coating of the aluminum honeycomb core 103 and the surface aluminum profile plate 101. The fireproof and heat-insulating coating adopts a nano aerogel coating with a thickness of 0.1-0.15mm.

[0038] The surface aluminum profile plate 101 has a wear-resistant layer on the outer side of the composite plate 1. The wear-resistant layer is an aluminum oxide coating, which gives the composite plate 1 good anti-corrosion and wear-resistant properties and extends its service life.

[0039] The wear-resistant layer also has a UV protection layer on its surface. The UV protection layer is made of fluorocarbon coating with a thickness of 0.03-0.05mm, which improves outdoor weather resistance.

[0040] Between the wear-resistant layer and the UV-resistant layer, there is a transparent conductive coating (ITO indium tin oxide) with a thickness of 0.005-0.01mm. This coating does not affect the appearance and wear resistance of the board, but also forms an "auxiliary shielding layer" on the outside to reflect high-frequency electromagnetic waves. Together with the inner copper mesh, it forms a "double-layer shielding". The ITO coating has a temperature resistance of ≥250℃, adheres stably to the original UV-resistant layer, and does not affect the fire resistance and weather resistance.

[0041] The aluminum honeycomb core 103 is filled with sound insulation cotton, which can significantly improve the sound insulation performance of the composite board. The aluminum honeycomb core 103 and the surface aluminum profile plate 101 are fixed and bonded with glue, which improves the structural stability of the entire board.

[0042] The sound insulation cotton is also mixed with expanded vermiculite filler, with a mass ratio of 7:3. When exposed to high temperatures, the expanded vermiculite can expand to form a fire barrier and enhance fire resistance.

[0043] The honeycomb cells are in the shape of regular hexagons. This hexagonal structure allows the aluminum honeycomb core 103 to be more uniform under pressure, thus improving the overall strength of the composite panel.

[0044] Among them, the honeycomb holes are gradient pore structure, with the pore size gradually increasing from the center to the edge, to adapt to the stress and sound insulation requirements of different locations;

[0045] The inner wall of the honeycomb core is uniformly sprayed with a nickel-phosphorus alloy conductive coating with a thickness of 0.02-0.03mm. The chemical plating process ensures that the coating is free of pinholes and continuous. The conductive coating can form an "intermediate shielding barrier" and together with the high-purity copper mesh on the surface and the conductive rubber layer of the frame 102, form a "three-layer three-dimensional shielding" to block the penetration path of electromagnetic waves inside the board. The nickel-phosphorus alloy coating has a temperature resistance of ≥300℃ and is stable in adhesion with the nano aerogel coating, without affecting the heat insulation and fireproof performance of the aluminum honeycomb core 103.

[0046] It also includes a reinforcing skeleton 104 embedded in the aluminum honeycomb core 103;

[0047] The reinforcing skeleton 104 is distributed in a cross shape, and the height of the reinforcing skeleton 104 is adapted to the thickness of the aluminum honeycomb core 103. The cross-shaped reinforcing skeleton 104 can effectively improve the overall strength of the composite panel 1. The reinforcing ribs 104 and the aluminum honeycomb core 103 are bonded together with glue, so that the two are stably connected together, further enhancing the stability of the structure.

[0048] Among them, a thin copper plating layer with a thickness of 0.01-0.02mm is set on the surface of the reinforcing skeleton 104. It is achieved by electroplating process. After copper plating, it can be used as a "shielding auxiliary skeleton". Together with the nickel-phosphorus coating of the aluminum honeycomb core 103 and the surface copper mesh, it forms a three-dimensional conductive network, further refines the shielding path, and reduces the diffraction of electromagnetic waves in the board.

[0049] Specifically, a 45° oblique skeleton is set in the cross-shaped structure of the reinforcing skeleton 104, increasing the height of the 45°+45° oblique skeleton to match the thickness of the aluminum honeycomb core 103. The skeleton material is carbon fiber reinforced aluminum matrix composite material with a density ≤2.8g / cm³. 3 With a tensile strength ≥450MPa, it is double-fixed to the aluminum honeycomb core 103 by "embedded snap-fit ​​+ high temperature resistant adhesive";

[0050] Among them, miniature temperature sensors and stress sensors are also built into the edge of the composite plate 1, and data is transmitted to the power storage station monitoring system in real time via a wireless module.

[0051] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
