Multi-unit power generation systems, however, struggle to achieve efficient energy circulation due to complex coordinated control. Furthermore, wear and noise from traditional transmission components further limit system reliability. Summary of the Invention

[0029] The power transmission module includes a worm gear reduction device, a carbon fiber composite flywheel and a permanent magnet synchronous generator.

[0030] The worm gear reduction device consists of an alloy steel worm and a powder metallurgy worm gear. The two axes are staggered 90 degrees and have an integrated lubricating oil circulation cooling system. The carbon fiber composite flywheel is configured in a vacuum chamber and supported by magnetic levitation bearings. The speed range is 0-20,000rpm. The permanent magnet synchronous generator is connected to the flywheel with an output frequency of 0.1Hz-130Hz and uses AC / DC hybrid power supply.

[0031] The input end of the worm gear reduction device is rigidly connected to the drive shaft of the external power source, and the output end of the worm gear reduction device is coupled to the central axis of the carbon fiber flywheel through a coupling to transmit the reduced-speed mechanical energy. The flywheel is installed in a vacuum explosion-proof cabin through a magnetic levitation bearing, and its rotational kinetic energy directly drives the rotor of the permanent magnet synchronous generator through coaxial transmission.

[0032] The cyclic power generation network includes multiple modular motor groups and a single crankshaft and a right-angle lever linkage.

[0033] Multiple modular motor groups are connected in series through high-molecular polyethylene ropes with a tensile strength of ≥800MPa. The surface of the polyethylene rope is coated with an anti-UV layer. A single crankshaft and right-angle bar connecting rod mechanism mechanically couples the output end of the motor group with the next-stage flywheel to form a closed-loop kinetic energy-electrical energy conversion link.

[0034] Multiple modular motor groups are connected in series through polymer polyethylene ropes, and the two ends of the ropes are fixed to the output shaft slots of adjacent motor groups. The output shaft of a single motor group is hinged to the drive shaft of the next-stage flywheel through a right-angle bar connecting rod mechanism, forming a mechanical energy transmission link. The electric energy output by the generator is distributed to each motor group through cables, driving its rotor to rotate. The mechanical energy output by the motor group drives the next-stage flywheel through the connecting rod, forming a closed loop.

[0035] The intelligent control module includes a variable frequency speed regulation unit and an Internet of Things sensor group.

[0036] The variable frequency speed regulation unit dynamically adjusts the speed ratio of the worm gear reduction device, with a speed ratio of 1:10 to 1:100. The IoT sensor group monitors the flywheel speed, winding temperature and current parameters in real time, and predicts equipment loss through AI algorithms.

[0037] The IoT sensor group is one or more of a speed sensor, a temperature probe, and a current transformer. The IoT sensor group is embedded in the flywheel compartment, generator windings, and motor group bearings, and communicates with the central controller through wireless signals. The central controller sends instructions to the variable frequency speed regulation unit according to load requirements to dynamically adjust the worm input speed.

[0038] Safety protection components include a flywheel explosion-proof compartment, an emergency magnetic brake and an insulation monitoring circuit.

[0039] The flywheel explosion-proof cabin adopts a carbon fiber-titanium alloy composite shell, the response time of the emergency magnetic brake is ≤0.5 seconds, and the leakage current threshold monitored by the insulation monitoring circuit is ≤1mA.

[0040] The flywheel explosion-proof cabin encloses the flywheel and magnetic levitation bearing, and is fixed to the generator casing through flange bolts. The coil winding of the emergency magnetic brake is linked to the central controller, triggering the brake after receiving an overspeed or overtemperature signal. The insulation monitoring circuit is connected in parallel to the generator output end to detect the cable-to-ground insulation resistance in real time.

[0041] Through the series connection of modular motor groups and a single crankshaft-right-angle bar connecting rod mechanism, a closed-loop link of "mechanical energy → electrical energy → mechanical energy" is formed to realize the cascade utilization of energy. The carbon fiber composite flywheel is combined with a magnetic levitation bearing and a vacuum chamber design to increase energy density, reduce mechanical friction loss, and improve charging and discharging efficiency. The speed ratio of the worm gear reduction device is adjusted in real time according to load demand to control the fluctuation of the flywheel speed and improve the stability of the power grid frequency. The Internet of Things sensor group monitors the speed, temperature and current parameters in real time. The AI algorithm predicts equipment loss and issues early warning, which reduces the failure rate and extends the life of the equipment.

[0042] The flywheel explosion-proof cabin uses a carbon fiber-titanium alloy composite shell, which can withstand impacts of 10 times the rated speed, with zero debris leakage, the emergency magnetic brake response time is ≤0.5 seconds, the insulation monitoring circuit leakage current threshold is ≤1mA, and double protection prevents fire and equipment damage. The polymer polyethylene rope is resistant to UV rays and corrosion. The polymer polyethylene rope replaces metal chains, which can reduce weight and improve installation and maintenance efficiency. The worm gear reduction device has an integrated lubricating oil circulation cooling system, stable transmission efficiency, and the motor group is plug-and-play, flexible to expand, and reduces expansion costs. When used on vehicles, it can be used as a vehicle-mounted range extender.

[0043] The present invention systematically solves the problems of low energy utilization, short equipment life, poor environmental adaptability and many safety hazards in traditional new energy power generation technologies through the efficient transmission of a worm gear reduction device, the combination of flywheel energy storage and multi-unit cyclic power generation, intelligent dynamic control and full-scenario safety protection, and provides a new generation of high-efficiency, low-cost, zero-emission power generation solutions for the fields of transportation, industry and microgrids.
