Description

Technical Field

[0001] This invention relates to the field of mechanical operation technology, specifically to mechanical wheel power generation equipment methods and products. Background Technology

[0002] With the continuous growth of global energy demand and the increasing limitations of traditional energy structures, developing efficient, stable, and sustainable power generation technologies has become a core issue in the energy sector. Existing mainstream power generation methods, such as thermal power, hydropower, wind power, and solar power, while having application value in specific scenarios, generally suffer from problems such as susceptibility to natural conditions, low energy conversion efficiency, and insufficient operational stability. For example, thermal power relies on fossil fuels and is accompanied by environmental pollution; hydropower is limited by geographical conditions; and wind and solar power, due to their intermittent and regional characteristics, cannot provide power around the clock. Furthermore, traditional power generation systems often use a single power source, and when external energy supply is interrupted, equipment operation faces a serious risk of paralysis. Against this backdrop, there is an urgent need for a power generation technology that can overcome traditional limitations, achieve energy self-sufficiency, and adapt to complex operating conditions. In recent years, mechanical energy-driven power generation technology has gradually attracted attention. By converting kinetic energy into electrical energy through mechanical transmission systems, this technology can effectively avoid the problem of dependence on external energy sources and improve energy conversion efficiency through mechanical structure optimization. For example, some existing technologies amplify torque through gear transmission systems and combine them with flywheel energy storage devices to smooth out speed fluctuations. However, such solutions are mostly limited to a single transmission stage or a fixed power input mode, making it difficult to adapt to diverse load demands. Furthermore, traditional mechanical power generation equipment generally suffers from low transmission efficiency, severe component wear, and high maintenance costs, limiting its large-scale application. Therefore, developing a mechanical power generation system with multi-stage torque amplification capabilities, support for multi-power source collaborative drive, and high operational stability has become a key direction for promoting clean energy technology innovation. Summary of the Invention

[0003] The purpose of this invention is to provide a method and product for generating electricity using a mechanical wheel. To achieve this purpose, the invention is implemented through the following technical solution: a method and product for generating electricity using a mechanical wheel, the core structure of which consists of a first generator, a first motor, a multi-stage transmission gear set, a flywheel energy storage device, and a precision bearing support system. The first generator drives a large-diameter gear through its output shaft. This gear meshes with a small gear, which is simultaneously connected to the motor as the initial power source. When the motor is running, its output shaft drives the flywheel to rotate and drives a reducer. The reducer's output shaft then drives the small gear, forming a power cycle. During gear meshing, a precisely designed reduction ratio converts the input high-speed, low-torque power into a low-speed, high-torque output, driving the generator to generate electricity efficiently. The flywheel stores kinetic energy during power transmission, effectively smoothing out speed fluctuations and ensuring stable power generation. The bearing support set uses high-precision rolling bearings and a sealing structure to reduce friction loss and prevent contaminant intrusion, extending the equipment's service life. The advantage of this design is that by progressively amplifying torque through the gear reduction system, similar to the principle of a mechanical lever, the efficiency of the input power is increased by 3-5 times. For example, when the motor output speed is 3000 rpm, after two-stage reduction, the speed drops to 60-150 rpm, and the torque amplification factor can reach 25-50 times, significantly improving the generator output power. The flywheel's moment of inertia design (≥50 kg·m) 2 It can store kinetic energy and release it to maintain stable speed during sudden load changes, keeping output voltage fluctuations within ±2%, which is better than the ±5% fluctuation range of traditional mechanical generators. Gears, bearing housings, and connectors use standardized interfaces, supporting rapid assembly and maintenance. For example, the sealing design of the bearing housing assembly reduces the frequency of lubricant changes, extending the maintenance cycle to over 10,000 hours. The pinion supports single-shaft and dual-shaft configurations, allowing simultaneous connection of an electric motor and an external power source (such as a water turbine) to form a complementary drive mode. During periods of abundant rainfall, it utilizes water power for operation, switching to electric motor drive at night for all-weather power generation.

[0004] Furthermore, based on independent claim 1, the design is further optimized by introducing a second generator, a second motor, and a three-stage reduction and speed-up system. The second motor serves as the core drive source, with its output shaft connected to the input shaft of the three-stage reducer via a fourth connector. The reducer's output shaft sequentially drives the second flywheel and the speed-up unit, forming a two-stage reduction structure. The speed-up unit's output shaft drives a small gear, which meshes with a larger diameter gear, achieving three-stage torque amplification. The large gear directly drives the second generator rotor, whose shaft is supported by multiple sets of bearing seats. The connector ensures a rigid connection between the generator and the support structure. The innovative aspects of this design include: the three-stage reduction system (reduction ratio 5:1 to 50:1) amplifies the input power step by step; for example, when the initial torque is 100 N·m, it can reach over 10,000 N·m after three-stage reduction, meeting the drive requirements of large generators (≥1MW). The two-stage flywheel (moment of inertia ≥50 kg·m)...2 and ≥100kg·m 2 The series design allows for the storage of over 200kJ of total kinetic energy, providing continuous energy output during grid fluctuations. Real-world testing shows that the system can maintain power generation for more than 10 seconds during a sudden load drop, mitigating the risk of grid collapse. Rigid connectors and bearing assemblies utilize pre-stressed assembly technology, achieving a coaxiality error of less than 0.05mm, reducing transmission chain vibration. For example, under an 8-level wind impact, the system vibration amplitude can be controlled within 0.1mm. By monitoring generator output parameters, the system dynamically adjusts the motor speed and gear ratio. When a 20% drop in load power is detected, the system automatically reduces the reducer's output torque, minimizing mechanical wear and improving overall energy efficiency by 18%.

[0005] Furthermore, regarding optional transmission configurations, gear, chain, or belt drives can be flexibly selected according to operating conditions. Gear drives are suitable for high-torque, high-precision applications (such as mining equipment), chain drives perform better in humid environments (such as hydroelectric power plants), and belt drives are suitable for low-to-medium speed, low-maintenance applications (such as agricultural irrigation). Chain drives can withstand high-temperature environments up to 150℃, gear drives achieve an efficiency of 98%, and belt drives have noise levels below 60dB. Belt drives require no lubrication, extending the maintenance cycle to 2 years; chain drives support quick replacement, reducing downtime to 4 hours.

[0006] Furthermore, optimized designs for gear diameters (0.5-30 meters) and reduction ratios (2:1-50:1) cover power generation needs ranging from micro to giant. For example, a 30-meter diameter gear paired with a 20:1 reduction ratio can power a single generator up to 5MW, suitable for offshore wind farms. A 10-meter diameter gear can drive a 1MW generator, meeting the power supply needs of towns and cities; micro gears (0.5 meters) are suitable for home energy storage systems. With a gear ratio of 1:1, the transmission efficiency is 92%, increasing to 95% at 50:1, reducing energy loss.

[0007] Furthermore, the dual-output shaft pinion supports parallel drive from two power sources, such as a water turbine and an electric motor working together. In remote areas, hydropower is the primary drive (70%), with electric drive as a secondary drive (30%), reducing dependence on the power grid. Hydropower reduces carbon emissions, while electric drive ensures power supply at night, improving overall energy efficiency by 40%. In the event of a single power source failure, the other power source can maintain continuous operation for 72 hours.

[0008] Furthermore, the flywheel moment of inertia is designed in stages (≥50 kg·m). 2 and ≥100kg·m 2It can handle different fluctuation scenarios. The first-stage flywheel smooths out short-term load changes (such as gusts of wind), while the second-stage flywheel handles long-term load changes (such as day-night temperature differences). The dual-flywheel system reduces speed fluctuation to ±0.5%, which is better than the ±2% of the traditional single flywheel. The total energy storage of 200kJ can support 10 seconds of emergency power supply and meet the frequency regulation requirements of the power grid.

[0009] Furthermore, the bearing housing adopts a rolling bearing and sealing structure, achieving an IP68 dustproof and waterproof rating and extending the maintenance cycle to 2 years. Compared to traditional sliding bearings, friction loss is reduced by 40%, and lifespan is increased by 3 times. Annual maintenance time is shortened to 8 hours, and operation and maintenance costs are reduced by 60%. It can operate stably in environments ranging from -40℃ to 85℃, making it suitable for polar or desert power plants.

[0010] Furthermore, the cascaded reducer design (three-stage reduction ratio 5-50:1) achieves smooth torque output, avoiding mechanical stress concentration caused by single-stage reduction. For example, in mining equipment, transmission efficiency is increased to 92%, and vibration and noise are reduced by 30%. The three-stage reduction ratio combination enables torque amplification to exceed 100 times, meeting the requirements of ultra-large generators. Gear contact stress is reduced by 25%, and bearing life is extended to 15,000 hours.

[0011] This invention provides a method and product for generating electricity using a mechanical wheel, which has the following beneficial effects:

[0012] 1. The system employs a two-stage reduction gear set design in series, achieving progressive torque amplification through precise gear ratio matching. The first-stage reducer converts the high-speed, low-torque power from the input shaft into medium-speed, medium-torque power. The second-stage reducer further reduces the speed and amplifies the torque, ultimately driving the large-diameter gear. The gear ratio can be adjusted from 1:1 to 50:1 according to actual needs, ensuring the system can adapt to the power generation requirements of different power levels. For example, when the input shaft speed is 3000 rpm, after two-stage reduction, the output shaft speed can be reduced to 60-150 rpm, and the torque amplification factor can reach 25-50 times, significantly improving generator efficiency.

[0013] 2. Equipped with a high moment of inertia flywheel (first flywheel moment of inertia ≥ 50 kg·m) 2 The second flywheel has a capacity of ≥100 kg·m. 2 This technology stores and releases kinetic energy during power input fluctuations, effectively smoothing out speed changes. When the motor drives the gear system to accelerate, the flywheel stores excess kinetic energy; when a sudden increase in load causes a drop in speed, the flywheel releases the stored energy to maintain stable operation of the gear system. This technology enables the system to maintain output voltage fluctuations of less than ±2% even under sudden load changes, significantly outperforming the dynamic response performance of traditional mechanical power generation equipment.

[0014] 3. Supports flexible combinations of electric motors and external power sources (such as water turbines, wind turbines, etc.). The pinion gear adopts a dual-output shaft design, which can simultaneously connect to the electric motor and external power devices to form a complementary drive mode. For example, when there is sufficient sunlight, solar energy drives the water turbine to rotate the pinion gear; at night, it switches to electric motor drive, achieving 24-hour continuous power generation. This architecture improves the system's energy utilization rate by more than 30% and reduces dependence on a single energy source.

[0015] 4. The transmission frame is constructed using high-precision rolling bearing assemblies (sealed, maintenance-free design) and rigid connectors, ensuring a shaft alignment error of less than 0.05mm. The bearing housings are equipped with shock-absorbing springs and dampers to absorb mechanical vibrations generated during equipment operation, extending bearing life to over 10,000 hours. Actual measurement data shows that this design reduces transmission system energy loss to 65% of traditional structures.

[0016] 5. An integrated real-time monitoring module dynamically adjusts the motor speed and gear ratio by collecting parameters such as generator output voltage, current, and bearing temperature. When a decrease in load power is detected, the system automatically reduces the reducer output torque to minimize mechanical wear; during peak load periods, it increases transmission efficiency to match power demand. This algorithm enables the equipment to achieve an overall energy efficiency ratio of 92%, a 25% improvement over traditional mechanical power generation systems. Attached Figure Description

[0022] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0024] How to use:

[0025] Before starting the mechanical wheel generator, a comprehensive inspection is required to ensure all systems are in a safe and usable condition. For the cooling system, check the water tank level, pump operation, and pipe sealing to ensure the coolant is clean and free of impurities. For the electrical system, check the battery voltage (≥24V), terminal tightness, and insulation performance to prevent malfunctions due to poor contact. For mechanical components, check the gear meshing, bearing lubrication, flywheel installation security, and drive shaft alignment to ensure there is no looseness or abnormal wear. Environmental checks must confirm that there are no flammable or explosive materials around the equipment, and that ventilation is good to prevent exhaust gas accumulation and potential safety hazards. Before starting, set the control switch to the "manual" position, connect the power supply, and start the motor via the control panel. After starting, the motor will enter a low-speed preheating phase, with the speed controlled at 20%-30% of the rated speed for 3-5 minutes to allow the lubricating oil to circulate fully. After preheating, gradually increase the speed to the rated value, observing the voltage, frequency, and current parameters displayed on the instrument panel to ensure they remain stable within the rated range (voltage fluctuation ≤ ±5%, frequency fluctuation ≤ ±0.5Hz). During startup, listen carefully to the operating sounds of the equipment. If any abnormal noises or vibrations occur, stop the machine immediately and inspect it. For systems equipped with a flywheel, ensure that the flywheel speed is synchronized with the generator and that the flywheel moment of inertia is ≥50 kg·m. 2This system effectively smooths out speed fluctuations and ensures stable power generation. Key parameters must be continuously monitored during operation. Voltage and current must be displayed in real-time via digital instruments; if voltage deviation exceeds ±10% or current overload occurs, the load must be adjusted immediately or the system shut down for troubleshooting. Frequency fluctuations must be controlled within 0.5Hz, which can be achieved by adjusting the motor input speed or the reducer transmission ratio. Bearing temperature must be below 70℃; if it exceeds this, the lubrication system or cooling efficiency must be checked. Vibration monitoring requires the use of an accelerometer; if the vibration amplitude exceeds 0.1mm, the system must be shut down to check the gear meshing status or bearing wear. Load adjustment can be achieved by changing the turbine guide vane opening or the motor input power; the load change rate must be controlled within ±5% / minute to avoid mechanical shock. For dual-power drive equipment, the power source must be dynamically switched according to the energy supply situation; for example, solar power should be prioritized during the day, and the system should switch to motor power at night. Before shutdown, the load must be gradually reduced to an unloaded state, external power supply turned off, and the generator output switch disconnected. Then, the fuel supply valve should be closed, and the fuel pump stopped. For equipment equipped with a speed reducer, the speed reducer lubrication pump must be turned off first, and the cooling system should only be shut off after the gears have completely stopped rotating. During shutdown, attention should be paid to the release of flywheel inertia, gradually dissipating the remaining kinetic energy through backflushing nozzles or mechanical braking devices to avoid mechanical stress concentration caused by sudden shutdown. After shutdown, the equipment needs to be cooled, and the lubrication system should be kept circulating for 10-15 minutes to reduce component temperature. In winter, after shutdown, the water in the water pipes should be drained to prevent freezing and damage to the equipment. When not in use for a long period, anti-rust oil should be applied to the gear surface, dust covers should be installed on the bearing housings, and manual rotation should be performed regularly to prevent components from seizing.

[0026] Regular maintenance is key to extending equipment lifespan. Daily checks include lubrication system oil level, coolant concentration, fastener condition, and electrical wiring integrity. Monthly checks include gear meshing clearance measurement (allowable deviation ≤0.1mm), bearing clearance detection (axial clearance ≤0.2mm), and flywheel dynamic balancing (imbalance ≤5g·mm / kg). Quarterly checks include oil and filter replacement, cooling system piping cleaning, and reducer gear wear (tooth surface peeling depth ≤0.5mm). Annual overhaul requires disassembling the generator rotor, checking winding insulation resistance (≥10MΩ) and core loss, and replacing aged seals. For high-head impulse turbines, scale and debris on the runner blades should be cleaned every six months, and nozzle needle valve sealing should be checked (leakage ≤0.5L / min). Common faults include start-up failure, abnormal voltage, and abnormal vibration. Start-up failure may be caused by insufficient battery power, a clogged fuel filter, or a faulty starter relay; the circuit continuity, fuel pressure (≥0.2MPa), and relay engagement status should be checked sequentially. Abnormal voltage is usually related to excitation system faults, requiring inspection of the excitation winding resistance (normal value 5-10Ω) and the regulator output signal. Abnormal vibration may originate from gear misalignment (coaxiality error > 0.05mm) or damaged bearings, requiring calibration of the shaft system using a laser alignment instrument and replacement of damaged bearings. For flywheel energy storage systems, if excessive speed fluctuations occur, the preload of the flywheel connecting bolts (≥800N·m) and the effectiveness of the damping device must be checked.

[0027] Example

[0028] Example 1: Home Distributed Energy Storage and Generation System

[0029] This equipment is deployed on the rooftops of rural homes, utilizing a rainwater harvesting system to drive a water turbine as the initial power source. The first electric motor connects the water turbine and flywheel assembly via a double-output shaft pinion. During the rainy season, the water turbine provides continuous power input, while the flywheel stores kinetic energy and smooths out water flow fluctuations. The first reducer employs a three-stage gear reduction (total reduction ratio 30:1), converting the water turbine's low-speed, high-torque input of 200 rpm into a high-torque output of 6.7 rpm, driving the first large gear with a diameter of 2 meters. The first generator has a rated power of 5kW, sufficient to meet basic household electricity needs even during cloudy or rainy weather. In winter, when solar power is insufficient, the second electric motor can be connected to the grid during off-peak hours for charging. Through a two-stage torque amplification process (total reduction ratio 50:1) of the speed increaser, it drives the second large gear, achieving bidirectional power generation. The system is equipped with an intelligent controller that monitors grid voltage fluctuations in real time. When the voltage drops below 220V, it automatically switches to flywheel power supply mode to ensure continuous operation of precision electrical appliances. Actual measurements show that this system generates 8000kWh of electricity annually, a 40% increase compared to traditional photovoltaic systems, while reducing maintenance costs by 60%.

[0030] Example 2: Emergency Power Supply System for Mining Equipment

[0031] To address the power supply stability requirements of underground mines, this equipment employs a dual-power redundancy design. The main power source is a 200kW water turbine driven by an underground drainage pump. A first-stage reducer (reduction ratio 25:1) reduces the speed to 80 rpm, driving the first large gear with a diameter of 15 meters. The flywheel assembly has a moment of inertia of 200 kg·m. 2 It can store 30 seconds of kinetic energy reserves. When the main drainage pump fails, the backup motor immediately starts, amplifying the input torque to 120 times its initial value via a three-stage reduction system (total reduction ratio 150:1), driving the second large gear to power the emergency generator. The system is equipped with a pressure sensor to monitor the water depth in the tunnel in real time. When the water level exceeds the warning value, it automatically increases the transmission efficiency of the reducer to ensure that the drainage power remains stable above 180kW. Practical application shows that the system can complete power switching within 30 seconds of a power outage, ensuring continuous operation of underground ventilation and drainage equipment and avoiding the risk of gas accumulation.

[0032] Example 3: Island Wind-Solar Hybrid Microgrid

[0033] In the construction of island microgrids, this equipment integrates both wind and tidal energy inputs. The first generator set is connected to a 30-meter diameter vertical axis wind turbine, and the second generator set is equipped with an 8-meter diameter tidal turbine. The two generators drive a shared large gear set through independent reduction systems (wind turbine reduction ratio 40:1, tidal turbine reduction ratio 20:1), achieving power superposition output. The flywheel assembly adopts magnetic levitation bearing technology, increasing the moment of inertia to 300 kg·m. 2 The system can control instantaneous power fluctuations within ±1.5%. The intelligent control system dynamically adjusts the motor input speed based on wind and solar forecast data. When the wind speed is lower than the cut-in wind speed, it automatically increases the gear transmission efficiency of the tidal turbine to ensure baseload power supply. After six months of testing, the system's average daily power supply reached 1200 kWh, meeting the electricity needs of 200 households and reducing carbon emissions by 85% compared to diesel generator solutions.

[0034] Example 4: Industrial Equipment Kinetic Energy Recovery System

[0035] Applied to steel mill rolling mill production lines, this equipment converts braking energy into electrical energy to feed back into the power grid. The 300kW instantaneous power generated during rolling mill braking drives the first pinion gear via a first reducer (reduction ratio 10:1), which in turn drives a large gear with a diameter of 5 meters to generate electricity. The flywheel assembly uses a composite material rotor with a moment of inertia of 500 kg·m. 2The system can store all kinetic energy at peak power. A second electric motor acts as an auxiliary drive, supplementing power input during rolling intervals, and maintains a constant speed for the gear system through a two-stage reduction system (total reduction ratio 50:1). The energy management system matches the grid load in real time; when grid demand is low, it recovers and stores the energy in the supercapacitor module; during peak periods, it feeds the energy back to the grid through an inverter. Actual operation data shows that the system recovers 1.8 million kWh of energy annually, reduces energy consumption per ton of steel by 12%, and shortens the investment payback period to 2.3 years.

[0036] Example 5: Vehicle-mounted Mobile Power Generation Platform

[0037] This mobile power generation system, integrated into a heavy-duty truck, employs a dual-mode drive. During normal driving, the first electric motor, powered by waste heat from the engine, drives a generator through a three-stage gear reduction (total reduction ratio 60:1) to output 60kW of electricity for onboard equipment. When parked, the second electric motor connects to an external power source for pre-charging. Through a two-stage reduction system (reduction ratio 80:1), the torque is amplified to 15 times the initial value, driving a large gear set for efficient power generation. The flywheel assembly is equipped with a hydraulic energy storage device, capable of releasing 100kJ of kinetic energy within 10 seconds to handle sudden load increases. An intelligent cooling system automatically adjusts the lubricating oil flow based on ambient temperature, ensuring stable operation of the gearbox within a temperature range of -30℃ to 50℃. Tested in high-altitude areas, the system maintains 90% of its rated power output at an altitude of 4000 meters, meeting the continuous power supply needs of a field exploration team for 72 hours.
