Description

Technical Field

[0001] This invention belongs to the field of clean energy power equipment technology, specifically relating to a high-efficiency magnetic levitation strong wind-driven energy conversion engine that uses air (including natural wind) as the power medium. The engine employs three types of bearings—high-speed bearings, air-suspended bearings, and magnetic levitation bearings—that are independently configured, allowing them to operate individually or in tandem to support a high-speed rotating shaft. Through a multi-stage permanent magnet backward-curved multi-bladed fan impeller combined with internal gas reversal, it achieves multi-stage pressurization and power generation. This is a new generation of high-end clean energy power core technology equipment capable of high speed, high power, high efficiency, ultra-low energy consumption, zero pollution, long lifespan, and stable operation. It can be widely applied in new energy vehicles, ships, distributed power generation, construction machinery, and various general-purpose power drive systems. Background Technology

[0002] Traditional internal combustion engines generate high-pressure gas by mixing and burning air and fuel to drive pistons or impellers to do work. The intake method is somewhat similar to that of this invention, but they generally have inherent defects such as serious emissions pollution, low thermal efficiency, large mechanical wear, significant torque attenuation at high speeds, and prominent vibration and noise.

[0003] Conventional fluid dynamic impellers mostly adopt axial flow blades, forward-curved blades, and radial straight blade structures, which have problems such as insufficient wind pressure, high wind resistance, easy airflow dissipation, low energy utilization, and poor operational stability, making it difficult to meet the demand for high-power and high-efficiency power output.

[0004] Existing pure electric drive systems rely on direct drive from the electric motor, which has shortcomings such as insufficient stability at high speeds, linear torque output, significant heat loss, and limited range, making it impossible to fully upgrade traditional fuel-powered devices.

[0005] To address the shortcomings of the existing technology, this invention uses air (including natural wind) as the power medium. A high-pressure, high-speed fluid is generated by a high-speed magnetic levitation turbine power source fan, which drives a four-stage permanent magnet backward-curved multi-bladed fan impeller to rotate and do work. The airflow flows through each stage of the impeller in sequence and forms a counter-current circulation in the internal cavity, repeatedly impacting the blades to achieve multi-stage power superposition.

[0006] The entire rotating system employs a collaborative support system comprised of high-speed bearings, air-suspended bearings, and magnetic suspended bearings. These three types of structures operate independently or in tandem, achieving ultra-low friction operation under all working conditions. The impeller magnetic poles utilize an alternating arrangement of inner N poles and outer S poles, with the outer N poles exceeding the inner S poles, further enhancing the magnetic field driving force and operational stability. This engine exhibits characteristics of increasing power and torque with higher speeds, demonstrating significantly superior overall performance compared to traditional internal combustion engines and ordinary pure electric motors. Summary of the Invention

[0007] This invention discloses a high-efficiency magnetic levitation strong wind-driven energy conversion engine, which aims to overcome the technical defects of existing internal combustion engines, such as high pollution, high energy consumption, weak high-speed power, poor high-speed stability and insufficient torque of ordinary electric motors, and low airflow utilization and high friction loss of conventional impellers.

[0008] This engine uses air (including natural wind) as its power source. It generates high-pressure, high-speed airflow through a high-speed magnetic levitation turbine power source fan, which sequentially drives a four-stage permanent magnet backward-curved multi-bladed fan impeller to rotate. The airflow forms a controllable reverse flow circulation in the internal cavity, impacting the blades multiple times to do work, thus achieving power superposition at each stage.

[0009] The rotating support system is composed of a combination of high-speed bearings, air-suspended bearings, and magnetic-suspended bearings. These three types of structures are independent and can work individually or in tandem. This achieves contactless, low-friction, high-rigidity, and high-stability support across the entire speed range. The permanent magnet backward-curved multi-bladed fan impeller employs a directional magnetic pole arrangement structure: the inner N pole is aligned with the outer S pole, and the outer N pole is aligned with the inner S pole. Furthermore, the number of outer magnetic poles exceeds the number of inner magnetic poles, forming a continuous, balanced, and high-intensity magnetic field driving field, ensuring smooth and vibration-free high-speed rotation of the impeller.

[0010] The overall structure includes three independent structural components: the casing, the main air inlet, the high-speed magnetic levitation turbine power source fan, the motor, and the high-speed bearings (air suspension bearing and magnetic levitation bearing). These components can work independently or in tandem. Other components include the support system, centrifugal impeller, flywheel, four-stage permanent magnet backward-curved multi-bladed fan impeller, multiple sets of drive shafts, internal and external permanent magnets, fluid pipes, sealing isolation plates, noise-absorbing exhaust components, dual battery power supply system, and intelligent electronic control system.

[0011] This invention requires no fuel combustion, produces no exhaust emissions, and its power output continuously increases with speed. It also boasts advantages such as high power density, high energy conversion efficiency, ultra-low energy consumption, low noise, and long lifespan. Its overall performance is significantly superior to that of traditional fuel engines and ordinary pure electric motors, demonstrating outstanding novelty, inventiveness, and practicality. Beneficial effects

[0012] 1. This engine uses magnetic levitation bearings, which achieves no mechanical contact and no friction loss of rotating parts, significantly reducing operating resistance and heat loss, greatly improving energy conversion efficiency, effectively reducing vibration and noise, and significantly extending the service life of the whole machine.

[0013] 2. The magnetic levitation bearing operation mode can minimize mechanical losses, save more electricity and energy under the same power output conditions, significantly improve the utilization rate of electrical energy, and effectively extend the driving range.

[0014] 3. The high-speed bearing, air suspension bearing, and magnetic suspension bearing are independently configured, allowing them to operate individually or work together to provide support. The high-speed rotating shaft achieves ultra-low friction, high stability, and high load-bearing capacity across the entire speed range, significantly improving the overall reliability and stability of the machine.

[0015] 4. The impeller adopts a permanent magnet backward-curved multi-bladed fan structure. The magnetic poles are arranged alternately with the inner magnetic N pole and the outer magnetic S pole, and the outer magnetic N pole and the inner magnetic S pole. The number of outer magnetic poles is greater than that of inner magnetic poles, forming a continuous and stable strong magnetic field drive. The impeller rotates smoothly and evenly, and the power output is efficient and stable.

[0016] 5. The engine is equipped with a four-stage permanent magnet backward-curved multi-blade fan impeller. Air (including natural wind) is used as the power medium. The airflow passes through sequentially and forms a counter-current circulation inside, repeatedly impacting the blades to do work, realizing multi-stage power superposition, and significantly improving the overall output torque and continuous power performance.

[0017] 6. Traditional internal combustion engines generally suffer from the technical defect that power decreases as the engine speed increases after startup. However, the newly developed engine has the opposite advantage, exhibiting the unique advantage that power increases as the engine speed increases and the wind force increases. The overall performance of the engine is significantly better than that of traditional internal combustion engines and ordinary pure electric motors. It solves the problems of high pollution, low efficiency, high noise, and rapid wear of internal combustion engines, while overcoming the defects of ordinary electric motors such as high-speed torque attenuation, limited range, and severe heat generation.

[0018] 7. Using air (including natural wind) as the sole power source, it eliminates the need for fossil fuel combustion, achieving true zero emissions and zero pollution, making it green and environmentally friendly, and fully in line with the national clean energy development strategy and the development direction of the high-end equipment industry.

[0019] 8. The intake drive logic is similar to that of traditional internal combustion engines, making the system highly adaptable and easy to quickly promote and apply in existing power scenarios such as vehicles, ships, and power generation equipment.

[0020] 9. High-pressure, high-speed airflow is provided by a high-speed magnetic levitation turbine power source fan, which has a rapid start-up response, strong instantaneous burst force, and acceleration performance that is significantly better than conventional power units.

[0021] 10. Permanent magnet backward-curved multi-bladed fan impeller has smooth air intake, low wind resistance, and concentrated air pressure. The airflow utilization rate is much higher than that of traditional axial flow, forward-curved and radial straight blade structures, and the energy loss is lower.

[0022] 11. Equipped with a combination structure of centrifugal impeller and flywheel, it can effectively store kinetic energy, stabilize speed, suppress fluctuations, and improve running smoothness and instantaneous heavy load capacity.

[0023] 12. The machine has a compact and simple structure, no complex combustion system, few vulnerable parts, low maintenance cost, and wide range of applications, making it highly valuable for engineering applications and promising for industrialization. Attached Figure Description

[0026] This embodiment is a high-efficiency magnetic levitation strong wind-driven energy conversion engine. It innovatively divides the whole machine into an external starting unit and an internal driven unit. The whole machine adopts a non-mechanical contact airflow transmission.

It includes three working models: a high-speed magnetic levitation turbine power source fan (3), a high-speed full-flow fan, and an air suspension fan.

[0027] (I) Overall machine structure division 1. External startup unit The high-speed magnetic levitation turbine power source fan (3) is the only power input core of the whole machine. It draws in air (including natural wind) as the power medium, and forms a high-pressure airflow through internal pressurization to supply the internal driven unit to do work. The high-speed magnetic levitation turbine power source fan controller (30) controls the start and stop of the whole machine and the speed level. The speed sensor (36) collects the speed signal in real time to form a closed-loop control.

[0028] 2. Internal driven unit The internal structure is equipped with four stages of permanent magnet backward-curved multi-bladed impellers, namely the first permanent magnet backward-curved multi-bladed impeller (8), the second permanent magnet backward-curved multi-bladed impeller (9), the third permanent magnet backward-curved multi-bladed impeller (10), and the fourth permanent magnet backward-curved multi-bladed impeller (11). The interior of the housing (1) is divided into a first large cavity (13) and a second large cavity (14) by a sealing isolation plate (19); The blade diameter of the first permanent magnet backward-curved multi-bladed impeller (8) is greater than or equal to the diameter of the main air inlet (2). The four impellers rotate in the same direction and are synchronously driven by the first central shaft (12), the second central shaft (15), and the main central shaft (16).

[0029] 1. Comparison of Standard Parameters for Conventional Fans Standard fan power: 1680W, air pressure 2.5kg / cm², air speed 89m / s, air volume 6.8m³ / h, rated speed 26000r / min, used as a unified benchmark.

[0031] 3. Airflow direction and impeller work logic The main air inlet (2) is arranged facing upwards, and the outside air flows through it in sequence: The main air inlet (2) and the main air inlet pipe (18) enter the equipment and are pressurized by the high-speed magnetic levitation turbine power source fan (3) and sent into the first large cavity (13); The first permanent magnet backward-curved multi-bladed impeller (8) discharges air upward and sends it into the second permanent magnet backward-curved multi-bladed impeller (9); The second permanent magnet backward-curved multi-bladed impeller (9) discharges air upwards, and the airflow enters the lower part of the second large cavity (14) through the fluid pipe (17), connecting with the air intake position below the third permanent magnet backward-curved multi-bladed impeller (10); The third permanent magnet backward-curved multi-blade impeller (10) discharges air downwards and directs it into the lower fan blade area of ​​the fourth permanent magnet backward-curved multi-blade impeller (11). The fourth permanent magnet backward-inclined multi-bladed impeller (11) discharges airflow, which passes through the tail silencer (20) and the tail wind deflector outlet (21) in sequence before being discharged outward; the four impellers rotate continuously in the same direction throughout the entire process.

[0032] 4. Three fan operating parameters and operating modes (1) High-speed full-flow fan The rated speed is 26,000 r / min, and the parameters are consistent with those of the benchmark fan.

[0034] (3) High-speed magnetic levitation turbine power source fan (3) The basic operating speed is 60,000 to 100,000 r / min, which is 4 times the performance of ordinary fans, and the maximum operating speed is 400,000 r / min.

[0035] 5. Energy-saving effect and power increase ratio Compared to ordinary structures, air-suspended fans consume three times less electricity and have twice the power. Compared with ordinary structures, the high-speed magnetic levitation turbine power source fan (3) consumes 5 times less electricity and increases power by 4 times.

[0036] 6. Air intake system The main air inlet (2) and the main air inlet pipe (18) introduce outside air, the air inlet (23) assists in air supply, and the sealing isolation plate (19) separates the internal cavity to prevent airflow from interfering with each other.

[0037] 7. Supercharged transmission system The inner permanent magnet connector (24) and the outer permanent magnet connector (25) form a magnetic coupling transmission, which drives the first conveyor belt (26) and the second conveyor belt (27) to carry out contactless power transmission, and cooperates with the fluid pipe (17), the first large cavity (13) and the second large cavity (14) to increase the pressure step by step.

[0038] 8. Exhaust and noise reduction system The tail muffler (20) attenuates the noise of high-speed airflow, and the tail windshield vent (21) stabilizes the airflow and prevents the backflow of external air.

[0039] 9. Power Supply and Intelligent Control System (1) Power supply unit The first battery (22) provides operating power for the high-speed magnetic levitation turbine power source fan (3), and the second battery (28) provides starting power for the motor (4). The intelligent controller (29) can switch between the two power sources and provide power in combination when either battery is out of power, ensuring the stable operation of the whole machine.

[0040] (2) Operational logic During the startup phase, the motor (4) and the high-speed magnetic levitation turbine power source fan (3) start synchronously; during the stabilization phase, after the fan (3) reaches a stable speed, the motor (4) automatically shuts down, and the fan (3) independently maintains the operation of the equipment.

[0041] (3) Functional module collaboration The fault warning module (31) monitors the equipment operating status in real time and issues a warning when there is an abnormality; the Bluetooth communication module (32) realizes short-distance data transmission and equipment control; the WiFi communication module (33) supports remote data interaction and monitoring; the engine positioning module (34) obtains equipment location information in real time; the start module (35) controls the equipment start-up process; the speed sensor module (36) collects the fan (3) speed data in real time to provide a basis for operation control.
