Their complex structures, often employing rigid and heavy components, lead to exorbitant maintenance and transportation costs. Furthermore, traditional electromagnetic wind turbines require large propellers to collect wind energy, necessitating high starting wind speeds (above level 4) and operation in open, unobstructed spaces. Magnetic levitation wind turbines, utilizing magnetic levitation technology, reduce frictional resistance, thus lowering the starting wind speed. However, magnetic levitation wind turbines require magnetic levitation technology and specialized materials, increasing their manufacturing and maintenance costs.

[0031] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to specific embodiments.

[0032] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution of the present invention are shown in the specific embodiments, while other details that are not closely related to the present invention are omitted.

[0033] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0034] Please see Figure 1 As shown, this invention provides a portable electromagnetic wind power generation device, comprising: an electromagnetic wind power generation unit and an energy storage unit electrically connected to the electromagnetic wind power generation unit; the electromagnetic wind power generation unit includes a flexible magnetic field module and a flexible cutting module electrically connected to the energy storage unit. The flexible cutting module cuts the magnetic field of the flexible magnetic field module under wind force to generate an electromotive force, which is stored and transmitted by the energy storage unit. This configuration makes the electromagnetic wind power generation unit a flexible structure, facilitating folding, storage, transportation, and assembly. Because the flexible cutting module is lightweight and flexible, it easily sways under wind force to achieve cutting and power generation.

[0035] Specifically, the flexible magnetic field module is one or more of magnetic yarn, magnetic rope, or magnetic fabric; the magnetic field strength is 0.5 mT-6 T. Please refer to [link / reference needed]. Figure 3 As shown, the magnetic rope comprises a magnetic material and a yarn substrate that is braided and wrapped around the surface of the magnetic material. Its preparation method can be as follows: the yarn substrate is wound onto a spindle and braided in a 2×2 structure using a 16-spindle rope braiding machine, while the magnetic material is fed in from the braiding points, resulting in a magnetic rope with an internal magnetic material and an external braided structure.

[0036] The magnetic material is a superparamagnetic particle, paramagnetic particle, or ferromagnetic particle, such as one or more of samarium cobalt magnets, neodymium iron boron magnets, ferrite magnets, AlNiCo magnets, and iron-chromium-cobalt magnets; the shape of the magnetic material includes, but is not limited to, one or more of block magnets, tile magnets, irregularly shaped magnets, cylindrical magnets, ring magnets, disc magnets, magnetic rod magnets, and magnetic frame magnets. The yarn substrate includes, but is not limited to, one or more of cotton, linen, wool, silk, polyester, nylon, polypropylene, acrylic, chlorofiber, and vinylon, with a diameter of 0.01-1 mm.

[0037] The flexible cutting module includes a wind-receiving substrate and a conductive cutting unit mounted on the substrate. The conductive cutting unit is electrically connected to a power storage unit. With this configuration, the wind-receiving substrate oscillates under wind force, causing the conductive cutting unit to cut the magnetic field of the flexible magnetic field module, generating an electromotive force. Because the wind-receiving substrate has a larger wind-receiving surface, it can fully utilize wind force to drive the conductive cutting unit to cut the magnetic field.

[0038] Specifically, the conductive cutting unit is made of conductive yarn, and the wind-receiving substrate is made of flexible fabric. The conductive yarn serves as part of the raw material for the flexible fabric, which is woven to achieve load-bearing capacity. Alternatively, the flexible fabric can be obtained first, and then the conductive yarn can be sewn or adhered to its surface. This arrangement facilitates the integrated assembly of the wind-receiving substrate and the conductive cutting unit, resulting in a simple structural design, low cost, and high practicality.

[0039] Please see Figure 2As shown, conductive yarns are loaded in a closed loop manner in a flexible fabric, and each flexible fabric contains 1-5000 conductive loops, each conductive loop having an area of ​​1 cm². 2 -100m 2 The diameter of the conductive yarn is 0.01~10mm. The shape of the conductive coil includes, but is not limited to, rectangle, circle, square, and triangle. The conductive composite yarn is embroidered into loops on one side of the flag fabric using computer embroidery, and then attached and encapsulated on another side of the flag fabric to create a conductive coil fabric. This process, reinforced by sewing, forms a composite flag with a sandwich structure of flag fabric / carbon fiber coil / flag fabric, resulting in a highly aesthetically pleasing flag with conductive coils that are not easily damaged and have a long service life.

[0040] Specifically, the conductive yarn is a core-spun or covered yarn, with the inner layer being a conductive layer and the outer layer an insulating layer. Its surface is insulated, making it difficult to break during sewing, and no voltage drop occurs between the conductive coils, thus increasing power generation efficiency. Please refer to [link to relevant documentation]. Figure 5 As shown, when carbon fiber conductive coil fabric is assembled with magnetic rope, a portable electromagnetic wind power generation flag device is obtained. Under the swing of the wind, the lightweight and soft carbon fiber conductive coil fabric swings, cutting the magnetic field lines generated by the magnetic rope, generating induced voltage and current, converting wind energy into electrical energy, and storing it with corresponding energy storage devices.

[0041] The conductive layer includes, but is not limited to, one or more of carbon fiber, copper wire, aluminum wire, silver wire, and gold wire; the insulating layer includes, but is not limited to, one or more of cotton, linen, wool, silk, polyester, nylon, polypropylene, acrylic, chlorofiber, and vinylon.

[0042] In some embodiments, the conductive yarn is prepared by the following steps: the material of the conductive layer is continuously fed into the wedge-shaped area of ​​a pair of rotating friction rollers in the same direction along a direction parallel to the friction roller axis of the friction spinning machine; the cotton fiber sliver of the insulating layer is combed into single-fiber cotton fiber slivers by a combing roller device; under the suction of negative pressure airflow, the cotton fiber slivers are fed into the wedge-shaped area of ​​a pair of rotating friction rollers in the same direction along a direction perpendicular to the friction roller axis, and are condensed and wrapped around the surface of the conductive layer for twisting to form an outer insulating conductive yarn.

[0043] The shape of the wind-receiving substrate includes, but is not limited to, rectangles, circles, squares, and triangles. This invention allows the wind-receiving substrate to be applied in a flag-shaped structure to streetlights, curtains, prayer flags, lighthouses, tunnel vents, etc.; the flag-shaped structure includes, but is not limited to, water-filled flags, company flags, knife flags, beach flags, tour guide flags, hand-held flags, team flags, and association flags. In use, several conductive cutting units on the wind-receiving substrate can be connected in series, parallel, or series-parallel. This configuration, because the electromagnetic wind power generation device of this invention has a fully flexible structure, allows for assembly and application in a flag-shaped structure, expanding application scenarios without affecting aesthetics, thus resulting in significant market value.

[0044] Specifically, please refer to Figure 4 As shown, the flexible magnetic field module and the flexible cutting module are connected by yarn weaving, and the magnetic fields of the flexible cutting module and the flexible magnetic field module are not parallel, preferably perpendicular to the magnetic field. For example, the carbon fiber conductive coil fabric is connected to the magnetic rope with thin rope or strips of cloth, or the carbon fiber conductive coil fabric is directly connected and assembled with magnetic rope. With this configuration, in use, the flexible magnetic field module can be set perpendicular to the horizontal plane, and the flexible cutting module can be set perpendicular to the flexible magnetic field module, and connected by yarn binding or weaving, so that the flexible magnetic field module can swing relative to the flexible magnetic field module.

The cotton fiber slivers are combed into single-fiber slivers by the combing roller device. Under the action of negative pressure airflow, they are fed into the wedge-shaped area of ​​a pair of rotating friction rollers in the same direction via a conveyor plate, perpendicular to the friction roller axis. At the same time, conductive carbon fibers unwound from the carbon fiber bobbin are continuously fed into the wedge-shaped area of ​​the pair of rotating friction rollers in the same direction via a yarn guide hole, parallel to the friction roller axis of the friction spinning machine. The friction rollers rotate at 2000-3000 r / m, agglomerating the cotton fiber slivers and wrapping them around the surface of the carbon fiber, twisting them to form a core-spun structure of an outer insulating conductive carbon fiber composite yarn. The conductive carbon fiber composite yarn is output by an active drafting roller, and then passes through a yarn guide hook that can move laterally in a slide rail, and is finally wound onto the core-spun yarn bobbin.

After sewing multiple rounds, another piece of flag fabric is used to cover it, and the process is reinforced by sewing to form a composite flag with a sandwich structure of flag fabric / carbon fiber coil / flag fabric.

[0051] The production method of the magnetic rope is as follows: Figure 3 As shown, the specific steps include the following:

[0052] The outer cotton yarn is wound onto the braiding spindle using a doubling machine, and then braided in a 2×2 structure using a 16-spindle rope braiding machine. The braiding spindles wrapped with cotton yarn are mounted on a yarn carrier device, which moves regularly around the braiding track. At the same time, a cylindrical magnetic core is fed in from the braiding point to obtain a magnetic rope with an external braided structure containing an internal cylindrical magnetic block.

[0057] Furthermore, these power-generating flags can be connected in series and are also foldable. Under wind speed conditions of 5.2 m / s, three flags can generate a peak voltage of approximately 7V.

Under the action of wind, the flag sways, at which point the magnetic field lines of the magnetic rope are cut, converting wind energy into electrical energy, but the voltage generated at the same wind speed is only 1.5V.

[0062] Example 4

[0063] Carbon fiber conductive yarn is prepared by wrapping insulating cotton fibers in the outer layer of carbon fiber through friction spinning. Rectangular carbon fiber conductive coil groups (20 cm long and 6 cm wide) are woven and fixed on flexible rectangular flag cloth through textile weaving technology.

[0065] Furthermore, carbon fiber conductive coil fabric is connected to woven magnetic rope with thin cords to assemble an electromagnetic wind-powered flag. When the flag sways in the wind, it cuts the magnetic field lines of the magnetic rope, collecting wind energy and converting it into electrical energy.
