Description

Technical Field

[0001] The present application relates to the field of wind power generation equipment, and in particular to a wind power generation device based on a friction nanogenerator. Background Art

[0002] Currently, ocean and land wind energy is primarily harvested through the construction of offshore wind energy collection stations or wind turbines. Wind power propels blades, causing them to rotate and drive electromagnetic generators, converting mechanical energy into electrical energy. However, these locations are severely limited, and they are expensive and environmentally unfriendly. Electromagnetic generators also lack maximum efficiency when harvesting low-frequency energy. To improve the utilization of low-frequency energy, scientists have developed triboelectric nanogenerator (TENG) technology and have developed wind power generation devices based on this technology.

[0003] However, the existing wind power generation device is still at a low level in terms of wind energy utilization. The existing wind power generation device is equipped with an empty box body that is rotated on a support. A plurality of stacked hollow boxes are placed in the empty box body. A number of small balls are placed in the hollow box body. An arc-shaped plate is installed at the other end of the empty box body. When generating electricity, it can only receive the force of the airflow in front of the arc-shaped plate, but cannot receive the airflow in other directions. Therefore, the arc-shaped plate only converts the wind energy in front into the kinetic energy of the empty box body rotating on the support. When the empty box body rotates, the small balls in the hollow box are driven to move irregularly, and the small balls The power generation device first converts wind energy into the kinetic energy of the curved plate, converts the kinetic energy of the curved plate into the mechanical energy of the hollow box, and then converts the mechanical energy of the empty box into the mechanical energy of the hollow box, and then converts the mechanical energy of the hollow box into the mechanical energy of the small ball, and then converts the mechanical energy of the small ball into the electrical energy generated by the friction between the small ball and the inner wall of the hollow box. It can be seen that wind energy is converted into electrical energy after being consumed at multiple levels, and the friction motion of the small ball on the inner wall of the hollow box is disordered and it is difficult to complete the stroke, resulting in low power generation efficiency.

[0004] Currently, no effective solution has been proposed to the problem that existing wind power generation devices have poor wind energy absorption capacity and low energy conversion efficiency, resulting in low power generation efficiency. Summary of the Invention

[0005] The present invention provides a wind power generation device based on a friction nanogenerator to solve the problem that the existing wind power generation devices have poor wind energy absorption capacity and low energy conversion efficiency during power generation, resulting in low power generation efficiency.

[0006] The present invention provides a wind power generation device based on a triboelectric nanogenerator. The wind power generation device based on a triboelectric nanogenerator comprises a plurality of wind collectors and a plurality of power generation units coaxially stacked and installed along a straight line. Each wind collector has a plurality of linear air ducts evenly distributed along its circumference. A central region is provided at the center of the wind collector, which is used to converge the airflow within the plurality of linear air ducts and / or allow the airflow within the plurality of linear air ducts to circulate with each other. At least one power generation unit is rotatably mounted in the horizontal direction within each linear air duct, and each power generation unit comprises two conductive carriers, a first insulator, and a rotating shaft. The two conductive carriers are symmetrically fixed on either side of the first insulator. The rotating shaft is rotatably mounted within an axial hole in the middle of the first insulator. The rotating shaft is rotatably mounted within the linear air duct. The two conductive carriers drive the first insulator to swing back and forth on the rotating shaft in response to the airflow. A sealed space is defined within each conductive carrier perpendicular to the rotating shaft, and the sealed space is filled with a plurality of friction layer balls.

[0007] Furthermore, the wind collector includes a circular disc, on which multiple triangular blocks with their tips pointing to the same center are evenly fixed along its circumference. The gaps between adjacent triangular blocks form a straight air duct, and a central area is formed between the tips of the multiple triangular blocks and the center of the disc.

[0008] Furthermore, the wind collector includes a cylinder, a plurality of straight channels are evenly opened on the cylinder along its circumference, a cylindrical groove is opened in the center of the cylinder as a central area, and the cylindrical groove is connected to the plurality of straight channels.

[0009] Furthermore, the conductive carrier is a container made of conductive material, the sealed space is a closed cylindrical channel, and a closed cylindrical channel is opened in the container along a direction perpendicular to the rotation axis; a plurality of friction layer balls are filled in the closed cylindrical channel.

[0010] Furthermore, the conductive carrier includes two conductors and a second insulator; the two conductors are fixed at both ends of the second insulator; the sealed space is a plurality of parallel closed cylindrical tracks, and the closed cylindrical tracks are filled with a plurality of friction layer balls; the closed cylindrical tracks are opened in the conductive carrier and span the two conductors and the second insulator in a direction perpendicular to the rotation axis.

[0011] Furthermore, the cross-section of the multiple parallel closed cylindrical tracks is honeycomb-shaped.

[0012] Furthermore, two power generation units are provided in each linear air duct, the power generation units at one end of the plurality of linear air ducts are located on the same circumference line, and the power generation units at the other end of the plurality of linear air ducts are located on the same circumference line.

[0013] Furthermore, the wind power generation device based on the friction nanogenerator also includes a base and multiple fixed shafts. The bottom ends of multiple wind collectors coaxially stacked in a straight line are installed on the base. Multiple axial holes are evenly opened on each wind collector along the circumferential direction. Multiple fixed shafts pass through the multiple axial holes in sequence from the top wind collector downward and are fixed to the base.

[0014] Furthermore, a solar panel seat is installed on the top of the uppermost wind collector, and a solar panel is installed on the solar panel seat. An energy storage device and an energy management circuit are set in the base to store the electricity generated by the solar panel and the power generation unit.

[0015] Furthermore, a transparent top cover is provided on the top of the solar panel seat.

[0016] Compared with the related art, the present invention has the following beneficial effects:

[0017] 1. The present invention utilizes a linear air duct structure to directly apply wind energy to the power generation unit, reducing the energy loss of the transmission structure. Under the gravity of the friction layer balls, a tapered channel is formed between the linear air duct structure and the power generation unit, thereby accelerating the flow rate of the airflow, thereby accelerating the swing frequency of the power generation unit, thereby improving the power generation efficiency. Compared with traditional electromagnetic generators, this device has a simple structure, a small size, a low cost, and a more reasonable overall structural arrangement, which effectively improves the power generation efficiency and solves the problem of low power generation efficiency caused by the poor wind energy absorption capacity and low energy conversion efficiency of existing wind power generation devices during power generation.

[0018] 2. The TENG structure of this device adopts an independent layer mode, which has higher power generation efficiency, and a honeycomb track structure is adopted inside the power generation unit to increase the contact area and space utilization. This is equivalent to a basic power generation structure being compressed into a minimum unit. The honeycomb structure is the structural optimization of the minimum unit. The multiple power generation units on the wind collector are a better structural optimization. The central area is connected to multiple straight air ducts. Finally, multiple power generation units are set on the same circumference to achieve resonance. The power generation unit and the straight air duct structure together enhance the reception and utilization of wind power. The device is interlocked layer by layer, and the power generation capacity is maximized in a limited space.

[0019] 3. The wind collector adopts a circularly distributed linear air duct structure, which can collect wind energy from all directions around it. The central area allows the airflow to move back and forth in multiple linear air duct structures to improve the utilization rate of wind energy.

[0020] 4. The device collects full-frequency and full-dimensional wind energy and solar energy by fixing the base on the ocean or land-related platforms, and can be used for the power supply direction or sensing of various equipment. In terms of design, the device can be stably fixed on the ocean and land-related platforms through the base. For example, it can be installed on a float to receive sea breeze and sunlight, and use the angle change brought by the float to increase the wind speed at a specific angle position of the wind collector to improve the utilization rate of wind energy. At the same time, the power generation part is modular, and the overall size can be large or small to meet different usage scenarios. At the same time, the device is also combined with a solar power generation module to realize solar energy collection, and one device can realize the collection of multiple energy sources. In the case of partial energy loss, such as the lack of wind energy and only light, or the lack of light and only wind energy, function switching can be achieved to improve the applicability of the device.

[0031] In an embodiment, a wind energy generation device based on a friction nanogenerator is provided. Figure 1 This is the overall appearance and structure diagram of the wind power generation device based on the friction nanogenerator. Figure 2 is the internal cross-sectional view of the device. Figure 1 and Figure 2As shown, from bottom to top, the device includes a base 5, on which a base cover 4 is mounted. A plurality of wind collectors 3 are stacked vertically in sequence. The wind collector 3 is evenly provided with a plurality of linear air ducts 10 along its own circumference. A power generation unit 7 is mounted in the linear air duct 10 for rotation. Airflow enters the linear air duct 10 of the wind collector 3 from all directions, driving the power generation unit 7 to swing, thereby causing the friction layer balls 17 in the power generation unit 7 to move and generate electricity. A solar panel holder 2 is mounted on the top of the top wind collector 3. A solar panel 6 is mounted on the solar panel holder 2 for receiving solar energy and generating electricity. A transparent top cover 1 is provided on the top of the solar panel holder 2. The transparent top cover 1 allows sunlight to pass through and blocks dust and debris, allowing the solar panel 6 to generate electricity while protecting the solar panel 6. The solar panel 6 is used to collect solar energy for power generation, and the wind collector 3 generates electricity by collecting wind energy. The plurality of wind collectors 3 are fixed to the base 5 by a fixed shaft 8. The device collects full-frequency and full-dimensional wind energy and solar energy by fixing the base 5 on an ocean or land-related platform, and can be applied to the power supply direction or sensing of various equipment. In terms of design, the device can be stably fixed on the ocean and land-related platforms through the base, such as being installed on a float to receive sea breeze and sunlight, and using the angle change brought by the float to increase the wind speed at a specific angle position of the wind collector 3, thereby improving the utilization rate of wind energy. At the same time, the power generation part is modular, and the overall size can be large or small, which can be used in different usage scenarios. At the same time, the device is also combined with a solar power generation module to realize solar energy collection, and one device can realize the collection of multiple energy sources. In the case of partial energy loss, such as the lack of wind energy and only light, or the lack of light and only wind energy, function switching can be achieved to improve the applicability of the device.

[0032] like Figure 3As shown, the specific structure of the air collector 3 is shown. The air collector 3 includes a disc 9. The disc 9 is evenly fixed with multiple triangular blocks with their tips pointing to the same center along its own circumference. The gaps between adjacent triangular blocks form a straight air duct 10. A central area is formed between the tips of the multiple triangular blocks and the center of the disc 9. The straight air duct 10 and the central area form a structure similar to an "air shaft", allowing the multiple straight air ducts 10 to form a connected air flow channel with the central area. Axial holes 11 are provided on the multiple triangular blocks, and multiple fixed shafts 8 pass through the multiple shaft holes 11 in sequence from the top air collector 3 downward to be fixed to the base 5. Screw holes 12 are provided on the multiple triangular blocks, and a top cover can also be provided on the top of each disc 9. The top cover is fixed to the disc 9 through the screw holes, so that each disc 9 and the top cover form a separate air inlet and outlet unit, making the whole modular and convenient for subsequent maintenance and improvement. The connected airflow channels allow the external airflow to enter the straight air duct 10 and then exit from one of the straight air ducts 10, but then escape through the central area to other straight air ducts 10 and flow back, thereby making full use of each airflow. Compared with the principle of using airflow to move fan blades to generate electricity in existing wind turbines, this principle can be more efficient when using airflow. In addition to the above-mentioned structure, the wind collector 3 can also be realized by other structures. That is, the wind collector 3 includes a cylinder, which is not shown in the figure. The cylinder is evenly provided with a plurality of straight channels 10 along its own circumferential direction, and a cylindrical groove is provided in the center of the cylinder as the central area. The cylindrical groove is connected to the plurality of straight channels 10. These two connection methods can be flexibly adopted, thereby improving the material selectivity during production, facilitating material selection, and reducing production costs.

[0033] Figure 2 Combine Figure 3 , a plurality of power generation units 7 are also provided in the wind collector 3. The power generation units 7 are horizontally installed in the straight air ducts 10, and at least one power generation unit 7 is installed in each straight air duct 10, and the power generation units 7 of the plurality of straight air ducts 10 are located on the same circumference line; in this embodiment, two power generation units 7 are provided in each straight air duct 10, the power generation units 7 at one end of the plurality of straight air ducts 10 are located on the same circumference line, and the power generation units 7 at the other end of the plurality of straight air ducts 10 are located on the same circumference line. Combined Figure 5 , you can see the specific state of the power generation unit 7 in the straight air duct 10. The design purpose of this structure is to improve the coordination between the power generation units 7. Under the resonance of multiple power generation units 7, the flow of air can be effectively promoted and the efficiency of airflow can be utilized. Compared with traditional structures, the energy utilization rate is higher.

[0034] Combine Figure 4 Each power generation unit 7 includes two conductive carriers, a first insulator and a rotating shaft 16; the first insulator is Figure 4The two conductive carriers are shown in the figure as the left and right sides of the first insulator. The middle part of the first insulator is rotatably connected to a rotating shaft 16, that is, the rotating shaft 16 is rotatably installed in the shaft hole in the middle part of the first insulator; the rotating shaft 16 is Figure 4 The figure shows the rotating shaft 16, which is not shown in the figure, but is represented by the shaft hole of the rotating shaft 16. As can be seen from the figure, the position where the rotating shaft 16 is installed is perpendicular to the wind direction of the linear air duct 10. In addition, the position where the rotating shaft 16 is installed can also be non-perpendicular to the wind direction of the linear air duct 10, that is, the rotating shaft 16 has a certain deflection angle compared to the wind direction of the linear air duct 10. Although the deflection effect may be worse than that of a vertical installation in this embodiment, after the shapes of the two conductive carriers and the first insulator undergo specific changes (such as elliptical), the non-perpendicular installation may have a better deflection effect. The overall axis direction of the power generation unit 7 is in the same direction as the wind direction. Then, after the airflow enters the linear air duct 10, the two conductive carriers will swing back and forth on the rotating shaft 16 along with the first insulator. Each conductive carrier is composed of three parts, namely, a hierarchical splicing method of conductor 13-second insulator 14-conductor 13. The second insulator 14 is the white strip in the figure, and the conductor 13 is the black part to the left and right of the second insulator 14. Several parallel cylindrical, closed cylindrical tracks 15 with a honeycomb structure are provided within the conductive carrier. These closed cylindrical tracks 15 span the three-layer structure of conductor 13, second insulator 14, and conductor 13. By loading several friction layer balls 17 within the closed cylindrical tracks 15, a complete power generation unit 7 is formed. As the two conductive carriers swing back and forth along with the first insulator on the rotating shaft 16, the several friction layer balls 17 roll back and forth within the closed cylindrical tracks 15, generating positive charges on the conductor 13 and negative charges on the friction layer balls 17. Charge transfer occurs between the electrodes, generating current output. In this embodiment, the friction layer balls 17 are PTFE balls, but PTFE balls are not the only choice for the friction layer. Any electronegative polymer insulating material can be used as the friction layer, such as PVC balls. The conductor 13 is generally made of metals with good conductivity such as copper and aluminum, as well as materials that can be 3D printed. The conductive carrier and the first insulator can be printed and manufactured using 3D printing technology to reduce production costs; the friction layer balls 17 are preferably made of polymer materials with good electronegativity, such as fluorine-containing materials, fluorinated isopropylene FEP, polyvinylidene fluoride (PVDF), polytetrafluoroethylene PTFE, etc.

[0035] Combine Figure 6In the traditional TENG power generation structure, friction layer balls are used to move irregularly in an empty small box to achieve friction power generation. However, the power generation of this power generation structure is uncontrollable, and how to simplify the structure to pursue greater power generation efficiency is a difficult problem. In order to solve this problem, the present invention discloses a new wind power generation structure based on friction nanogenerator. Figure 6 This is a cross-sectional view of the power generation unit 7. It is clear from the figure that the total length of the friction layer balls 17 is equal to the length of the conductors 13 on either side of the second insulator 14. When the friction layer balls 17 pass through the second insulator 14, the charged particles are retained on the second insulator 14, increasing the electric field strength there and thus enhancing power generation capacity. In terms of structure, wind ducts are evenly distributed in the circumferential direction of the wind collector 3, and the wind energy is directly applied to the power generation unit through the wind duct, reducing the energy loss of the transmission structure. At the same time, the power generation unit 7 is tilted in the wind duct under the gravity of the friction layer balls 17. At this time, the wind duct structure will be conical, which will increase the wind speed and accelerate the swing frequency of the power generation unit. At the same time, the TENG structure of the device adopts an independent layer mode, which has higher power generation efficiency, and the power generation unit adopts a honeycomb track structure to increase the contact area and space utilization. It is equivalent to a basic power generation structure being compressed into a minimum unit. The honeycomb structure is the structural optimization of the minimum unit. The multiple power generation units 7 on the wind collector 3 are better structural optimization. The central area is connected to multiple straight air ducts 10. Finally, multiple power generation units 7 are set on the same circumference to achieve resonance. The power generation unit 7 and the straight air duct 10 structure together enhance the reception and utilization of wind power. The device is layered and the power generation capacity is maximized in a limited space.

[0036] The present invention designs a novel wind energy generation structure based on a triboelectric nanogenerator. Multiple linear air ducts 10 are evenly distributed around the circumference of a wind collector 3. Each linear air duct 10 houses a generator unit 7. When wind blows through the wind collector 3, it enters the interior of the wind collector 3 through the linear air ducts 10, driving the generator units 7 in the linear air ducts 10 to swing up and down around a rotation axis 16. Multiple closed cylindrical tracks 15 are located within a conductive body 13, each containing a number of PTFE balls. As the generator units 7 swing up and down around the axis, the PTFE balls roll back and forth on the closed cylindrical tracks 15, positively charging the conductive material and generating negative charges on the surfaces of the PTFE balls. As the PTFE balls roll back and forth, a potential difference is generated, thereby achieving current output. Compared with traditional electromagnetic generators, this device has a simpler structure, smaller size, lower cost, and a more rational overall structural arrangement, effectively improving power generation efficiency. This solves the problem of poor wind energy absorption and low energy conversion efficiency of existing wind power generation devices.

[0037] like Figure 7As shown, the triboelectric nanogenerator-based wind energy generator also includes a base 5, on which is mounted an energy storage device 18 and an energy management circuit 19. The energy management circuit 19 is used to store the electricity generated by the wind collector 3 in the energy storage device. A solar panel base 2 is mounted on top of the wind collector 3. The solar panel base 2 and the energy management circuit 19 are used to store the electricity generated by the wind collector 3 in the energy storage device. This invention is a triboelectric nanogenerator-based wind energy generator. It utilizes a linear air duct 10 to directly apply wind energy to the power generation unit, reducing energy loss in the transmission structure. Under the weight of the PTFE spheres, the air duct structure assumes a conical shape, increasing wind speed and accelerating the oscillation frequency of the power generation unit 7. The TENG structure adopts an independent layer model, resulting in higher power generation efficiency. The honeycomb track structure within the power generation unit 7 increases contact area and space utilization. Compared with traditional electromagnetic generators, the device has a simpler structure, smaller size, and lower cost. This solves the problems of traditional electromagnetic generators, such as large size, high cost, and low efficiency in collecting low-frequency wind energy. At the same time, the device is also combined with a solar power generation module to achieve light energy collection, and a single device can achieve multiple energy collection. This invention provides more options for the friction nanogenerator in terms of structural design, material selection, and processing and manufacturing of power generation units. The above describes in detail the preferred embodiment of the present invention in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiment. Within the scope of the technical concept of the present invention, various simple variations of the technical solution can be made, and these simple variations all fall within the scope of protection of the present invention. For example, changes in the shape, material, and size of the shell, especially adjustments to the friction layer material and conductive material.

[0038] In summary, the present invention utilizes the straight air duct 10 structure to directly apply wind energy to the power generation unit 7, thereby reducing the energy loss of the transmission structure and forming a tapered channel between the straight air duct 10 structure and the power generation unit 7 under the gravity of the friction layer ball 17, thereby accelerating the flow rate of the airflow, thereby accelerating the swing frequency of the power generation unit 7, and thus improving the power generation efficiency; the TENG structure of the device adopts an independent layer mode, which has higher power generation efficiency, and the power generation unit adopts a honeycomb track structure inside to increase the contact area and space utilization, which is equivalent to a basic power generation structure being compressed into a minimum unit, the honeycomb The wind collector 3 adopts a circularly distributed linear air duct 10 structure, which can collect wind energy from all directions. The central area can allow the airflow to move back and forth in the multiple linear air duct 10 structures to improve the utilization rate of wind energy.
