Specific implementation

[0024] The technical scheme in the embodiments of the utility model will be apparently and completely described below with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without making creative labor belong to the range of protection of the utility model.

[0025] In the description of the utility model, it is necessary to explain that, unless there is explicit stipulation and limitation, the term "installation", "connection", "connect" should be broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integral connection, can be mechanical connection, also can be electrical connection, can be direct connection, also can be indirectly connected through the intermediate medium, can be the intercommunication of two elements. For the ordinary skill in the art, the specific meaning of the above-mentioned term in the utility model can be understood according to the specific situation.

[0026] Please refer to Figure 1 、 Figure 2 And Figure 3 An embodiment provided by the utility model: a braided aluminum belt for wind power generation cover body, comprising braided aluminum belt 1, the surface of braided aluminum belt 1 is connected with composite protection assembly, and the composite protection assembly is used for protecting braided aluminum belt 1 and internal structure;

[0027] The composite protection assembly includes the buffer energy absorption layer 2 connected on the surface of braided aluminum belt 1, the surface of buffer energy absorption layer 2 is penetrated and bonded with heat conduction silica gel layer 3, the surface of heat conduction silica gel layer 3 is connected with electromagnetic shielding enhancement layer 4, the surface of electromagnetic shielding enhancement layer 4 is connected with fire -retardant fiber layer 5, the surface of fire -retardant fiber layer 5 is connected with antioxidant protection layer 6, and the surface of antioxidant protection layer 6 is coated with hydrophobic coating 7.

[0028] Buffer energy absorption layer 2 is made of porous foam aluminum material, and the porosity is between 50%-80%, which is firmly combined with aluminum wire braid layer through adhesive.

[0029] The electromagnetic shielding enhancement layer 4 is woven by mixing copper wire and aluminum wire, the proportion of copper wire and aluminum wire is 1:3, and the weaving method is twill weaving.

[0030] Further, the buffer energy absorption layer 2 is tightly connected to the surface of the woven aluminum strip 1, is made of porous aluminum foam material with a porosity of 50%-80%, has good flexibility and buffering performance, is like countless tiny springs, can absorb and disperse energy by deformation when subjected to external physical impact, is firmly combined with the aluminum wire woven layer through the adhesive, and ensures that the woven aluminum strip 1 and the internal structure are not damaged in the impact process, thereby effectively reducing the risk of damage to the woven aluminum strip 1 and the internal structure caused by collision. For example, when the wind power equipment encounters strong wind and is hit by foreign matter, the buffer energy absorption layer 2 can greatly reduce the damage of the impact force to the woven aluminum strip 1.

[0031] The heat-conducting silica gel layer 3 is permeated and bonded to the surface of the buffer energy absorption layer 2, has excellent heat conduction performance, can quickly conduct the heat generated by the woven aluminum strip 1 during operation, avoids heat accumulation to affect the performance of the equipment, and simultaneously, due to the existence of tiny gaps on the surface of the porous structure of the buffer energy absorption layer 2, the heat-conducting silica gel layer 3 can well fill the gaps, so that the protection structure is more compact, and the stability and integrity of the structure are enhanced.

[0032] The electromagnetic shielding enhancement layer 4 is woven by mixing copper wire and aluminum wire according to a proportion of 1:3 in a twill weaving manner, the good electrical conductivity of the copper wire is combined with the light weight characteristic of the aluminum wire, and the twill weaving increases the structural complexity of the shielding layer, so that the electromagnetic shielding enhancement layer 4 can effectively shield electromagnetic interference in a wider frequency range, and can provide reliable electromagnetic protection for the electronic elements in the equipment when the wind power equipment is running.

[0033] The fireproof and flame-retardant fiber layer 5 is connected to the surface of the electromagnetic shielding enhancement layer 4, is made of special high-temperature-resistant and flame-retardant fiber material, can prevent the spread of fire when encountering high temperature or open flame, reduces the risk of ignition of the woven aluminum strip 1, and guarantees the safe operation of the equipment in a fire hazard environment.

[0034] The oxidation-resistant protection layer 6 is located on the surface of the fireproof and flame-retardant fiber layer 5, and functions to prevent the woven aluminum strip 1 and the materials of the protection layers from being oxidized. The woven aluminum strip 1 exposed to air for a long time in an outdoor wind power environment is easily eroded by oxygen, which leads to a decrease in material performance, and the oxidation-resistant protection layer 6 can effectively delay this process and prolong the service life of the woven aluminum strip 1.

[0035] The hydrophobic coating layer 7 is coated on the outermost layer and has strong hydrophobicity, when encountering rainwater or water vapor such as dew, water droplets cannot be attached on the surface of the hydrophobic coating layer 7 and quickly slide off, thereby avoiding problems such as corrosion or short circuit caused by moisture entering the inside of the braided aluminum belt 1, and ensuring stable operation of the braided aluminum belt 1 in a humid environment.

[0036] Please refer to Figure 1 , Figure 2 and Figure 3 , the utility model provides an embodiment: a kind of braided aluminum belt for wind power generation cover body, the inside of braided aluminum belt 1 is connected with inner layer reinforcing braid 8;

[0037] Inner layer reinforcing braid 8 is woven by carbon fiber and aluminum wire, and the ratio of carbon fiber and aluminum wire is 1:4, and plain weave is used.

[0038] Further, the inner layer reinforcing braid 8 is connected to the inside of the braided aluminum belt 1, made of carbon fiber and aluminum wire in a ratio of 1:4 by plain weave, and the carbon fiber has the characteristics of high strength and high modulus. After mixing and weaving with aluminum wire, the overall strength and rigidity of the braided aluminum belt 1 can be significantly improved. The plain weave makes the braided structure more compact and uniform, while ensuring the flexibility of the braided aluminum belt 1, it enhances its tensile and bending resistance, effectively improving the performance of the braided aluminum belt 1 under complex stress conditions.

[0039] Please refer to Figure 4 and Figure 5 , the utility model provides an embodiment: a kind of braided aluminum belt for wind power generation cover body, one end of braided aluminum belt 1 is connected with magnetic liquid interlocking connection assembly, and magnetic liquid interlocking connection assembly is used to realize the connection and fixation between braided aluminum belt 1.

[0040] The magnetic liquid interlocking connection assembly includes a connecting block 9 connected to one end of the braided aluminum belt 1, a fixed plate one 10 and a fixed plate two 11 symmetrically arranged on one side of the connecting block 9, and the surfaces of the fixed plate one 10 and the fixed plate two 11 are installed with staggered limiting grooves 12 and limiting columns 13, and the limiting grooves 12 on the surface of the fixed plate one 10 correspond to the limiting columns 13 on the surface of the fixed plate two 11, and the limiting columns 13 on the surface of the fixed plate one 10 correspond to the limiting grooves 12 on the surface of the fixed plate two 11.

[0041] The limiting grooves 12 are provided with a magnetic liquid filling chamber in the inside, and the magnetic liquid filling chamber is made of elastic silica gel material.

[0042] One end of the limiting column 13 is embedded with a permanent magnet, and the surface of the permanent magnet is wrapped with a layer of nanoscale soft magnetic material film.

[0043] Further, the connecting block 9 is fixed at one end of the woven aluminum strip 1, and one side thereof is symmetrically connected with the fixed plate one 10 and the fixed plate two 11. When two woven aluminum strips 1 need to be connected, one end of one woven aluminum strip 1 is inserted into the fixed plate one 10 and the fixed plate two 11 on one side of the connecting block 9 of the other woven aluminum strip 1, and the limiting column 13 is inserted into the limiting groove 12 to preliminarily align the two woven aluminum strips 1 at the initial stage of connection, so as to prepare for stable connection.

[0044] The surfaces of the fixed plate one 10 and the fixed plate two 11 close to each other are respectively provided with the limiting groove 12 and the limiting column 13, and the limiting groove 12 is provided with a magnetic liquid filling chamber made of elastic silica gel material. When the limiting column 13 is inserted into the limiting groove 12, the elastic silica gel material can adapt to different degrees of deformation to ensure close fitting.

[0045] When the magnetic liquid is attracted by the permanent magnet embedded at one end of the limiting column 13, the magnetic liquid can tightly wrap the limiting column 13 by using its own fluidity. The nanoscale soft magnetic material film wrapped on the surface of the permanent magnet not only enhances the magnetic field stability of the permanent magnet, but also further improves the interaction with the magnetic liquid, so as to form strong adsorption force and sealing effect, realize stable and reliable connection and fixation between the woven aluminum strips 1, and effectively avoid connection loosening under the working conditions such as vibration of the wind power generation equipment, thermal expansion and cold contraction.

[0046] Working principle: when the wind power generation equipment encounters external physical impact, such as impact of strong wind and foreign matters, the buffer energy absorption layer 2 is the first to be impacted. Since the porous aluminum foam material with a porosity of 50%-80% is used, a large number of pores are like a micro spring structure. At the moment of impact, the aluminum foam material is elastically deformed, and the impact energy is converted into elastic potential energy of the material, so as to absorb and disperse a large amount of impact energy, effectively reduce the damage of impact force to the woven aluminum strip 1 and the internal structure, and reduce the damage risk.

[0047] During the operation of the wind power generation equipment, the woven aluminum strip 1 will generate heat due to various factors. At this time, the heat-conducting silica gel layer 3 plays a role. By virtue of excellent heat conduction performance, the heat generated by the woven aluminum strip 1 is quickly absorbed and conducted out along the material structure of the heat-conducting silica gel layer 3, so as to avoid the accumulation of heat on the woven aluminum strip 1 and affect the performance of the equipment. At the same time, since there are micro gaps on the surface of the porous structure of the buffer energy absorption layer 2, the heat-conducting silica gel layer 3 can fill the gaps during the penetration and bonding process, so that the entire protection structure is more compact, the stability and integrity of the structure are enhanced, and a better support foundation is provided for the subsequent protection layer.

[0048] In the complex electromagnetic environment around the wind power generation equipment during operation, the electromagnetic shielding enhancement layer 4 is made of copper wire and aluminum wire in a 1:3 ratio of twill weaving. The good conductivity of the copper wire enables it to guide the current generated by electromagnetic interference. The lightweight nature of the aluminum wire ensures that the overall mass of the shielding layer is not too heavy. The twill weaving method increases the structural complexity of the shielding layer, forming a special electromagnetic shielding network. When external electromagnetic interference signals enter, the shielding network can reflect, scatter and absorb electromagnetic interference signals multiple times, thereby achieving efficient electromagnetic shielding in a wider frequency range and providing reliable electromagnetic protection for electronic components inside the equipment, ensuring normal operation.

[0049] When encountering high temperature or open flame, the fireproof and flame-retardant fiber layer 5 begins to play a role. It is made of special high-temperature-resistant and flame-retardant fiber materials. These fiber materials can prevent the spread of fire in a high-temperature environment. On the one hand, the chemical structure of the fiber material makes it have high thermal stability and is not easy to ignite. On the other hand, when it comes into contact with a fire source, the fiber material will undergo a series of physical and chemical reactions, such as decomposition or carbonization, forming an isolation layer to prevent oxygen from contacting the woven aluminum strip 1 and the internal structure, thereby reducing the risk of the woven aluminum strip 1 being ignited and ensuring the safe operation of the equipment in a fire hazard environment.

[0050] In the outdoor wind power environment, the woven aluminum strip 1 and each protective layer material are exposed to air for a long time and are easily eroded by oxygen. The antioxidant protective layer 6 is located on the surface of the fireproof and flame-retardant fiber layer 5 and can prevent oxygen from directly contacting the underlying material. The material of the antioxidant protective layer 6 usually has antioxidant properties and can slowly react with oxygen, consume oxygen, or form a dense protective film on the surface of the material, thereby effectively delaying the oxidation process of the woven aluminum strip 1 and each protective layer material and prolonging the service life of the woven aluminum strip 1.

[0051] When encountering rainwater or dew, the hydrophobicity of the hydrophobic coating 7 plays a role. The surface microstructure and chemical properties of the hydrophobic coating 7 make it have very low surface energy for water, and water droplets cannot adhere to its surface and will quickly slide off, avoiding problems such as metal corrosion and short circuit caused by water intrusion into the woven aluminum strip 1, ensuring the stable operation of the woven aluminum strip 1 in a humid environment.

[0052] The inner reinforcing woven layer 8 is connected to the inner side of the woven aluminum strip 1, which is made of carbon fiber and aluminum wire in a 1:4 ratio by plain weave method. During the operation of the wind power generation equipment, the woven aluminum strip 1 will be subjected to various external forces, such as stretching or bending. The carbon fiber has the characteristics of high strength and high modulus. When the woven aluminum strip 1 is subjected to external force, the carbon fiber can bear most of the tension and bending stress, and cooperates with the aluminum wire. The plain weave method makes the woven structure compact and uniform. The aluminum wire provides certain flexibility and conductivity, ensuring that the woven aluminum strip 1 has good flexibility while enhancing its tensile and bending resistance, effectively improving the performance of the woven aluminum strip 1 under complex stress conditions, and ensuring that it maintains structural stability under various working conditions.

[0053] When two woven aluminum strips 1 need to be connected, one end of one woven aluminum strip 1 is inserted into the inside of the fixed plate one 10 and the fixed plate two 11 on one side of the connecting block 9 of the other woven aluminum strip 1. The limiting column 13 penetrates the woven aluminum strip 1 and is fixed in the limiting groove 12, so that the two woven aluminum strips 1 can be initially aligned at the initial stage of connection, and be prepared for stable connection.

[0054] After the fixed plate one 10 and the fixed plate two 11 are close to each other, the limiting groove 12 and the limiting column 13 start to work together. The limiting groove 12 is provided with a magnetic liquid filling chamber made of elastic silica gel material. When the limiting column 13 is inserted into the limiting groove 12, the elastic silica gel material can adaptively deform according to the shape and insertion angle of the limiting column 13, to ensure that the two are tightly fitted. A permanent magnet is embedded at one end of the limiting column 13. The permanent magnet generates a magnetic field. When the magnetic liquid is attracted by the magnetic field of the permanent magnet, it quickly gathers around the limiting column 13 by using its own fluidity to tightly wrap the limiting column 13. The nanoscale soft magnetic material film wrapped on the surface of the permanent magnet can enhance the magnetic field strength and stability of the permanent magnet. In this way, strong adsorption force and sealing effect are formed to realize stable and reliable connection and fixation between the woven aluminum strips 1, effectively avoiding connection loosening under the working conditions of vibration or thermal expansion and contraction of the wind power generation equipment.
