Description

Technical Field

[0001] This utility model relates to the field of new energy technology, and in particular to a wind power generation system. Background Technology

[0002] With the rapid development of renewable energy technologies, wind energy has received widespread attention as a clean and sustainable energy source. Traditional wind power generation devices typically rely on large wind turbines, which are complex in structure, costly, difficult to install and maintain, and require high wind speeds, making them difficult to widely apply in low-wind-speed or urban environments.

[0003] In recent years, triboelectric nanogenerators, as a novel energy harvesting technology, have shown great potential in the field of micro and small-scale wind energy harvesting due to their advantages such as simple structure, low cost, and high efficiency in converting low-frequency mechanical energy.

[0004] Existing technologies include several wind power generation devices based on triboelectric nanogenerators, such as cantilever beam, rotating, or flag-type structures. However, these devices generally suffer from problems such as unstable output power, poor wind resistance, low integration, and difficulty in large-scale deployment. Furthermore, existing triboelectric nanogenerator structures are mostly single-point or linear layouts with limited energy harvesting density, and their response performance is uneven under multi-wind-direction conditions.

[0005] Designing a wind power generation system that is structurally stable, responsive, easy to integrate, and capable of efficiently collecting wind energy from multiple directions has become a pressing technical problem in this field. Utility Model Content

[0006] To address the aforementioned problems, this utility model provides a wind power generation system.

[0007] The wind power generation system provided by this utility model includes six parallel support rods, which together form a regular hexagonal prism structure and respectively form the six lateral edges of the regular hexagonal prism.

[0008] Multiple triboelectric nanogenerator units are arranged along the axial direction of the regular hexagonal prism, and each triboelectric nanogenerator unit is spaced apart along the length direction of the support rod.

[0009] Each of the aforementioned triboelectric nanogenerator units includes six triboelectric nanogenerators, each of which is connected between two adjacent support rods, and its two ends are fixedly connected to the corresponding support rods.

[0010] The output terminals of the six triboelectric nanogenerators in the triboelectric nanogenerator unit are connected in series.

[0011] In the wind power generation system of this invention, multiple triboelectric nanogenerator units are connected in series with each other.

[0012] In the wind power generation system of this invention, multiple triboelectric nanogenerator units are connected in parallel with each other.

[0013] In the wind power generation system of this invention, the triboelectric nanogenerator includes a first electrode plate, a power generation film, and a second electrode plate stacked sequentially along the thickness direction.

[0014] The first electrode plate and the second electrode plate are respectively fixedly connected to two adjacent support rods at both ends, and there is a preset gap between the first electrode plate and the second electrode plate;

[0015] The power-generating film can vibrate under wind power and periodically contact and separate from the first electrode plate and the second electrode plate;

[0016] There are differences in the triboelectric sequence between the power-generating thin film and the first electrode plate, as well as between the thin film and the second electrode plate.

[0017] In the wind power generation system of this utility model, one end of the power generation film is fixedly connected to the support rod, and the other end is a free end.

[0018] In the wind power generation system of this invention, both ends of the power generation film are fixedly connected to the support rod, and the length is greater than that of the first electrode plate and the second electrode plate.

[0019] In the wind power generation system of this invention, the materials of the first electrode plate and the second electrode plate are selected from at least one of aluminum alloy, copper-steel alloy or nickel-steel alloy.

[0020] The wind power generation system of this utility model also includes a signal processing circuit and an energy storage element;

[0021] The input terminal of the signal processing circuit is electrically connected to the output terminal of the triboelectric nanogenerator unit, and is used to rectify and stabilize the output alternating voltage signal, converting it into a stable DC voltage signal and a pulse current signal.

[0022] The output terminal of the signal processing circuit is electrically connected to the energy storage element to store electrical energy in the energy storage element.

[0023] This utility model has the following beneficial effects:

[0024] 1. The system adopts a hexagonal prism frame structure formed by six support rods, which has a high degree of spatial symmetry and structural stability, effectively resisting wind loads from multiple directions and improving the system's environmental adaptability and service life.

[0025] 2. The regular hexagonal prism structure has sixfold symmetry in the horizontal plane, which enables the system to respond effectively to wind from any horizontal direction, realize omnidirectional wind energy collection, and significantly improve the energy capture efficiency in complex wind field environments.

[0026] 3. Multiple triboelectric nanogenerator units are arranged along the axial direction, with each unit containing six triboelectric nanogenerators, forming a distributed, modular energy harvesting structure. The output voltage and current can be flexibly adjusted through series or parallel connections to meet the power supply requirements of different application scenarios.

[0027] 4. The power-generating film vibrates under the action of wind, and periodically contacts and separates from the upper and lower electrode plates. It efficiently converts wind energy into electrical energy by utilizing triboelectric charging and electrostatic induction effects, which is especially suitable for low wind speed environments.

[0028] 5. The support rod and triboelectric nanogenerator have a simple structure, low requirements for processing precision, and a wide range of material choices, which is conducive to large-scale production and application.

[0029] In summary, the wind power generation system provided by this utility model has a novel structure, reliable performance, and high energy collection efficiency, and is particularly suitable for distributed wind power supply for low-power devices such as urban building microenvironments, IoT nodes, and smart sensors.

[0035] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0036] like Figure 1 , Figure 2As shown, this embodiment of the present invention provides a wind power generation system, including six parallel support rods 1, which together form a regular hexagonal prism structure and constitute the six side edges of the regular hexagonal prism; multiple triboelectric nanogenerator units 2 are arranged along the axial direction of the regular hexagonal prism, and each triboelectric nanogenerator unit 2 is spaced apart along the length direction of the support rods 1; each triboelectric nanogenerator unit 2 includes six triboelectric nanogenerators 3, which are respectively connected between two adjacent support rods 1, and their two ends are respectively fixedly connected to the corresponding support rods 1; the output ends of the six triboelectric nanogenerators 3 in the triboelectric nanogenerator unit 2 are connected in series to form a series circuit.

[0037] Preferably, the support rod 1 is a metal support rod made of aluminum alloy or stainless steel, which has good mechanical strength and weather resistance.

[0038] like Figure 1 As shown, six support rods 1 are arranged parallel to each other in space and evenly distributed circumferentially, forming a regular hexagonal prism frame structure. Multiple triboelectric nanogenerator units 2 are evenly spaced along the axial direction of the support rods, i.e., the height direction of the regular hexagonal prism. The length of the support rods 1, the spacing between adjacent triboelectric nanogenerator units 2, and the size of a single triboelectric nanogenerator 3 can all be adjusted according to the actual wind field conditions and output requirements. Figure 2 As shown, within each triboelectric nanogenerator unit 2, six triboelectric nanogenerators 3 are arranged to form a regular hexagon, with the included angle between adjacent triboelectric nanogenerators 3 being 120°, and each triboelectric nanogenerator 3 can generate electricity in the wind.

[0039] In this embodiment of the invention, a regular hexagonal prism frame structure is formed by six support rods, which has high spatial symmetry and structural stability, effectively resisting multi-directional wind loads and improving the system's environmental adaptability and service life. The regular hexagonal prism structure has sixfold symmetry in the horizontal plane, enabling the system to respond effectively to winds from any horizontal direction, achieving omnidirectional wind energy harvesting and significantly improving energy capture efficiency in complex wind field environments.

[0040] In some embodiments of this invention, multiple triboelectric nanogenerator units 2 are connected in series to improve the system output voltage.

[0041] In other embodiments of this invention, multiple triboelectric nanogenerator units 2 are connected in parallel to each other to improve the overall output current of the system.

[0042] In this embodiment of the invention, multiple triboelectric nanogenerator units are arranged along the axial direction, each unit containing six triboelectric nanogenerators, forming a distributed, modular energy harvesting structure. Through series or parallel connection, the output voltage and current can be flexibly adjusted to meet the power supply requirements of different application scenarios.

[0043] like Figure 3 As shown in some embodiments of this utility model, the triboelectric nanogenerator 3 includes a first electrode plate 31, a power generation film 32, and a second electrode plate 33 stacked sequentially along the thickness direction. The two ends of the first electrode plate 31 and the second electrode plate 33 are respectively fixedly connected to two adjacent support rods 1, and a preset gap exists between the first electrode plate 31 and the second electrode plate 33. The power generation film 32 can vibrate under wind force and periodically contact and separate from the first electrode plate 31 and the second electrode plate 33. There is a difference in triboelectric sequence between the power generation film 32 and the first electrode plate 31, and between the power generation film 32 and the second electrode plate 33, to generate charge transfer during the contact-separation process. The two ends of the first electrode plate 31 and the second electrode plate 33 are respectively fixed to two adjacent support rods by screws or welding, and a certain gap, for example, 1-5 mm, is maintained between them. One end of the power generation film 32 is fixed, and the other end is a free end, which can swing freely under wind force, periodically contacting and separating from the upper and lower electrode plates. It efficiently converts wind energy into electrical energy using triboelectric charging and electrostatic induction effects, making it particularly suitable for low-wind-speed environments.

[0044] In some embodiments of this utility model, one end of the power generation film 32 is fixedly connected to the support rod 1, and the other end is a free end.

[0045] In other embodiments of this invention, both ends of the power-generating film 32 are fixedly connected to the support rod 1, and its length is greater than that of the first electrode plate 31 and the second electrode plate 33. The power-generating film 32 oscillates under wind force, periodically contacting and separating from the upper and lower electrode plates.

[0046] The materials of the first electrode plate 31 and the second electrode plate 33 are selected from at least one of aluminum alloy, copper steel alloy or nickel steel alloy.

[0047] In some embodiments of this invention, the first electrode plate 31 and the second electrode plate 33 are aluminum alloy plates, and the power generation film is a PTFE (Polytetrafluoroethylene) film. PTFE and aluminum alloy have a significant difference in triboelectric sequence, which is beneficial for generating high-density surface charge. When wind blows, the power generation film vibrates under the excitation of the airflow, periodically contacting and separating from the first and second electrode plates, thereby inducing an alternating potential on the two electrode plates, realizing the conversion of wind energy into electrical energy.

[0048] In other embodiments of this utility model, the first electrode plate 31 and the second electrode plate 33 are copper-steel alloys or nickel-steel alloys, and the power generation film is a polymer material with different triboelectric electrode sequences, such as nylon or polyimide.

[0049] In this embodiment of the invention, the support rod 1 and the triboelectric nanogenerator 3 have simple structures, low requirements for processing precision, and a wide range of material options, which is conducive to large-scale production and widespread application.

[0050] In some embodiments of this invention, micro-nano structures are provided on the two surfaces of the power generation film 32, so that the power generation film 32 can make better contact with the first electrode plate 31 and the second electrode plate 33, thereby improving the output voltage and current of a single triboelectric nanogenerator 3.

[0051] In this embodiment of the invention, the wind power generation system further includes a signal processing circuit and an energy storage element. The input terminal of the signal processing circuit is electrically connected to the output terminal of the triboelectric nanogenerator unit, and is used to rectify and regulate the output alternating voltage signal, converting it into a stable DC voltage signal and a pulse current signal. The output terminal of the signal processing circuit is electrically connected to the energy storage element to store electrical energy in the energy storage element. The energy storage element is a supercapacitor or a lithium battery, used to store electrical energy for use by an external load.

[0052] It is understood that this invention can also be modified in various ways, such as increasing or decreasing the number of support rods to form a corresponding regular polygonal prism structure; or choosing other triboelectric nanogenerator structures.

[0053] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many modifications under the guidance of the present invention without departing from the spirit and scope of the claims. All of these modifications are within the protection scope of the present invention.
