Description

Technical Field

[0001] This application belongs to the field of wind energy utilization, and in particular relates to a wind speed adaptive triboelectric-electromagnetic induction hybrid wind power generator based on an inertial drive conversion mechanism and its operation steps. Background Technology

[0002] With rapid economic development, the use of electricity has gradually intensified. Currently, over 80% of my country's electricity is generated from fossil fuels such as coal, oil, and natural gas. As these non-renewable energy sources are continuously consumed in large quantities and environmental concerns intensify, this is no longer in line with the current concept of sustainable development. Developing new energy power generation is an urgent and long-term strategic task.

[0003] The technology of using solar, wind, tidal, or mechanical energy for micro- and nano-power generation has attracted widespread attention, and it is being combined with triboelectric nanogenerators that operate using the coupling effect of triboelectricity and electrostatic induction. Wind energy, a form of solar energy conversion, is a renewable natural energy source that produces no pollution emissions. Compared to solar, biological, geothermal, and ocean energy generation, wind power is currently the new energy source with the most technological and economic potential for large-scale commercial development.

[0004] In recent years, a new type of wind power generation system has emerged worldwide: the variable-speed constant-frequency generator set. Because its rotational speed is not limited by the generator's output power, it exhibits relatively good wind power collection and conversion efficiency. At low wind speeds, the rotational speed can change according to wind speed, thereby improving wind power conversion efficiency. At high wind speeds, the rotational speed is controlled by adjusting the turbine pitch angle, ensuring the safe operation of the variable-speed constant-frequency generator set. However, due to the relatively late development and production of wind turbines in my country, related core technologies are lacking. Wind turbines in China suffer from problems such as low collection efficiency and incomplete wind energy collection functions, making them unable to better adapt to various working environments.

[0026] The operation steps of a wind speed adaptive triboelectric-electromagnetic induction hybrid wind power generator based on an inertial drive conversion mechanism include the following processes:

[0027] (1) When the wind speed reaches a certain condition, the wind-driven limit rod wind cup rotates counterclockwise, and drives the drive gear to rotate through the wind power transmission shaft. According to the empirical formula, the transmission torque T can be listed as follows:

[0028]

[0029]

[0030] The output power of wind energy is related to the following parameters:

[0031]

[0032]

[0033]

[0034] (2) When the driving gear rotates counterclockwise, since the number of external meshing of the planetary gear set is 1, it drives the external gear ring to rotate clockwise.

[0038]

[0039] Then the speed of the external gear ring

[0040] (3) The rotation of the outer gear ring drives the octahedral sticky shell to rotate. The rabbit hair stuck on it rubs against the FEP film embedded in the copper sheet-FEP panel shell, causing the magnet disk to rotate. This causes the magnet disk cover and the inner ring of the cylindrical roller bearing to rotate. At the same time, the resistance provided by the resistance during this process provides the resistance torque. The following formulas are derived:

[0042]

[0043] )

[0044] (4) According to the requirements of the exercise, only when The generator will only operate at that time, as derived from the above formula:

[0045]

[0046] If the wind speed meets the above conditions, the generator will operate normally.

[0047] (5) When the wind speed reaches a certain condition, due to the increase in the rotation speed of the magnetic disk (207), the centrifugal force on the magnetic claw (206) increases until it is sufficient to overcome the magnetic force of the neodymium magnet attracting the magnetic claw (206). At this point, the magnetic claw (206) is thrown out of the magnetic disk (207), and its pointed head gets stuck in the slot inside the decahedral sticky shell (402), causing the decahedral sticky shell (402) to rotate. According to the formula, the magnetic force F has the following relationship:

[0049]

[0050] Magnetic moment

[0051]

[0052] when

[0053]

[0054] The above formulas derive that the adaptive portion will activate when the wind speed v satisfies the following relationship.

[0055]

[0056] Preferably, the triboelectric power generation capacity includes the following processes:

[0057] (1) The current I generated by the triboelectric part of this generator is derived based on the following formula.

[0065]

[0066] In summary, this application has the following beneficial effects:

[0067] (1) A mechanical inertial drive device is adopted:

[0068] The mechanical wind power drive system can operate in different modes depending on the wind speed, adapting to complex and ever-changing environments and greatly improving the efficiency of wind energy collection. It is energy-saving and environmentally friendly, as its rotor speed is driven by wind power, reducing electricity consumption. It also features a simple mechanical structure and low cost.

[0069] (2) Planetary gear structure is adopted:

[0070] Planetary gear structures enable high speed ratios and high torque output, thereby improving the conversion efficiency of triboelectric generators. Their small size and light weight allow for a combination of high torque output and compact dimensions. Furthermore, they reduce mechanical and frictional losses, further enhancing conversion efficiency. Since planetary gear structures operate based on gear transmission principles, triboelectric generators experience virtually no mechanical shock or noise during operation, ensuring long-term stable and safe operation.

[0071] (3) Integrated friction sensing:

[0072] The device organically combines triboelectric charging and magnetic induction to achieve the conversion of the two types of energy, thereby improving energy utilization and power generation efficiency. It can also maintain a relatively stable output power under different environments and working conditions, with high stability. The device has a simple structure, is easy to use, and adopts a pollution-free energy conversion method, making it environmentally friendly and energy-saving.

[0073] (4) Using rabbit hair as the friction electrode:

[0074] Rabbit hair has excellent triboelectric properties and is itself a very good insulating material, which can effectively reduce energy loss inside the generator and improve power generation efficiency. Rabbit hair used as a triboelectric electrode is less affected by changes in environmental factors, has high stability, and is low in cost. Rabbit hair is also soft, has good wear resistance, and has a long service life. Attached Figure Description

[0111] A second disc 5013 is disposed within the inner cylindrical structure of the copper sheet-FEP panel housing 501. Four gear shafts 5012 and a wind power transmission shaft 601 pass through the second disc 5013. The second disc 5013 covers the four planetary gears 305. Four insertion cylinders 50131 are fixedly disposed on the side of the second disc 5013 facing the first disc 3021. The four vertical rods 3022 of the gear frame 302 are inserted into the insertion cylinders 50131. Each of the four vertical rods 3022 has a first pin hole 30221 horizontally opened at the upper end. The four insertion cylinders 50131 have corresponding second pin holes 50132. The pins pass through the second pin holes 50132 and the first pin holes 30221 in sequence to form an interference fit, thereby realizing the fixed connection between the gear frame 302 and the copper sheet-FEP panel housing 501.

[0112] Reference Figure 17 The wind power conversion mechanism 6 includes a wind power transmission shaft 601 and a limiting rod wind cup 602. The limiting rod wind cup 602 is fixed to the top of the wind power transmission shaft 601, and the bottom of the wind power transmission shaft 601 is fixedly connected to the drive gear 304.

[0113] Reference Figure 10 , Figure 13 and Figure 17 The drive gear 304 has a spline groove 3042 at its center, and the bottom of the wind power drive shaft 601 has a spline protrusion 6011. The spline protrusion 6011 is inserted into the spline groove 3042 to form a transition fit. The bottom surface of the spline protrusion 6011 coincides with the bottom of the spline groove 3042, thereby realizing the connection between the wind power drive shaft 601 and the planetary gear structure 3.

[0114] Reference Figure 17 The limiting rod wind cup 602 includes a limiting rod 6021, a limiting block 6022 located in the middle of the limiting rod 6021, and wind cups 6023 set at both ends of the limiting rod 6021. The three limiting rods 6021 are respectively placed crosswise in three slots of different heights at the top of the wind power transmission shaft 601 to form a clearance fit. The spherical surfaces of the three pairs of wind cups 6023 point in the same direction and all rotate counterclockwise.

[0115] Reference Figure 2 , Figure 18 and Figure 19Wind energy is collected by the limit rod wind cup 602, driving the wind power transmission shaft 601 to rotate. The wind power transmission shaft 601 drives the drive gear 304 to rotate, and the drive gear 304 drives the outer gear ring 301 to rotate through the planetary gear 305. The outer gear ring 301 drives the octahedral sticky shell 401 to rotate, realizing the operation of the low-speed wind power generation device. When the wind speed increases, the three magnetic claws 206 automatically extend and engage with the limit slot 4021 opened in the inner ring of the octahedral sticky shell 402, driving them to rotate together, realizing the operation of the high-speed wind power generation device. The copper coil wound on the iron core placed inside the induction coil container 201 generates current by continuously cutting the magnetic field lines generated by the magnet in the rotating magnetic disk 207, realizing magnetic induction electricity generation. The wind speed adaptive triboelectric-electromagnetic induction wind power generator generates current in the induction electricity generation structure 2 under any working state; however, under low wind speed conditions, the current is mainly generated by the triboelectric power generation structure; under high wind speed conditions, the current is generated by the induction electricity generation structure 2.

[0116] The operating principle of a wind speed adaptive triboelectric-electromagnetic induction hybrid wind power generator based on an inertial drive conversion mechanism, as described in this application, is as follows:

[0117] Wind energy drives the wind power conversion mechanism 6 to operate, which in turn drives the planetary gear structure 3 to rotate. The outer gear ring 301 of the planetary gear structure 3 is inserted into multiple vertical grooves 4011 on the inner ring of the octahedral tufted shell 401 via multiple vertical protrusions 3011 on its outer contour edge, forming a transitional fit. This drives the friction rotor structure 4 to rotate, achieving wind energy transmission. The rabbit hair on the continuously rotating friction rotor structure 4 generates current through continuous friction between the copper sheet 502 and the FEP film 503 on the stator structure 5, forming a triboelectric nano-power generation structure. When the wind speed increases, the three magnetic claws 206 in the magnetic disk 207 extend due to centrifugal inertia and engage with the limiting slots 4021 on the inner ring of the octahedral tufted shell 402, rotating together.

[0118] In the induction-generating structure 2, the octahedral protrusion 2073 on the top of the magnet disk 207 forms a transition fit with the octahedral adhesive shell 401 at the bottom of the friction rotor structure 4. The rotation of the octahedral adhesive shell 401 drives the magnet disk 207 to rotate. The induction-generating structure 2 and the base 1 are fixed to the hexagonal protrusion 1012 on the bottom bearing seat 101 through the hexagonal slot at the bottom of the induction coil container 201. Thus, the copper coil wound on the iron core inside the induction coil container 201 continuously cuts the magnetic field lines to generate current, forming the electromagnetic induction-generating structure 2.

[0119] The operating steps and theoretical basis of a wind speed adaptive triboelectric-electromagnetic induction hybrid wind power generator based on an inertial drive conversion mechanism are as follows:

[0120] (1) When the wind speed reaches a certain condition, the wind-driven limit rod wind cup rotates counterclockwise, and drives the drive gear to rotate through the wind power transmission shaft. According to the empirical formula, the transmission torque T can be listed as follows:

[0121]

[0122]

[0123] The output power of wind energy is related to the following parameters:

[0124]

[0125]

[0126]

[0127] (2) When the driving gear rotates counterclockwise, since the number of external meshings of the planetary gear set is 1, it drives the external gear ring to rotate clockwise:

[0129]

[0130] Transmission ratio

[0131]

[0132] Then the speed of the external gear ring

[0133] (3) The rotation of the outer gear ring drives the octahedral sticky shell to rotate. The rabbit hair stuck on it rubs against the FEP film embedded in the copper sheet-FEP panel shell, causing the magnet disk to rotate. This causes the magnet disk cover and the inner ring of the cylindrical roller bearing to rotate. At the same time, the resistance provided by the resistance during this process provides the resistance torque. The following formulas are derived:

[0134]

[0135]

[0136]

[0137]

[0138] )

[0139] (4) According to the requirements of the exercise, only when The generator will only operate at that time, as derived from the above formula:

[0140]

[0141] If the wind speed meets the above conditions, the generator will operate normally.

[0142] (5) When the wind speed reaches a certain condition, due to the increase in the rotation speed of the magnetic disk, the centrifugal force on the magnetic claw increases until it is sufficient to overcome the magnetic force of the neodymium magnet attracting the magnetic claw. At this point, the magnetic claw is thrown out of the magnetic disk, and its pointed head gets stuck in the slot inside the decahedral sticky shell, causing the decahedral sticky shell to rotate. According to the formula, the magnetic force F has the following relationship:

[0143]

[0144]

[0145] Magnetic moment

[0146]

[0147] when

[0148]

[0149] The above formulas derive that the adaptive portion will activate when the wind speed v satisfies the following relationship.

[0152]

[0153]

[0154] in

[0155]

[0156] (2) When the generator is running but the adaptive part is not started, the current I generated by the triboelectric generator has the following relationship.

[0157]

[0158] (3) When the generator is running and the adaptive part starts, the current I generated by the triboelectric generator has the following relationship.
