Attached Figure Description

[0024] Figure 1 This is a schematic diagram of the structure of a new energy air power generation system according to the present invention; Detailed Implementation

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See Figure 1 The illustrated new energy air power generation system includes a ventilator, a duct module, a wind turbine generator, and an intelligent control system. The ventilator generates controllable airflow, overcoming the limitations of natural wind. The core principle is to utilize ground air, creating negative pressure through the ventilator, thereby generating airflow within the duct to achieve power generation. The ventilator operates normally according to the principle of drawing in air at the negative pressure end and expelling air at the positive pressure end. When the ventilator diameter is much smaller than the inlet cross-section, and the outlet is located inside the inlet cross-section, a series of physical phenomena that help improve power generation efficiency occur. The high-speed airflow discharged from the positive pressure end of the ventilator enters the larger inlet cross-section, not only increasing the kinetic energy of the air in the inlet area but also helping the negative pressure end overcome duct resistance. Simultaneously, the synergistic effect of the positive and negative pressures of the ventilator triggers a siphon effect, further aiding in overcoming duct resistance. Furthermore, the rotating blades of the modular wind turbine generator and the swirl wind turbine generator within the duct generate pressure, enhancing the duct's ability to overcome resistance. The power generation ventilation system is carefully designed with series, parallel, overlapping, recirculation, and swirl flow, which allows the airflow in the duct to impact the impeller blades secondary or even multiple times, significantly improving power generation efficiency.

[0027] The optimized duct design employs series, parallel, overlapping, and swirling structures to achieve multiple airflow impacts on the blades, improving energy utilization. 1. Duct Layout: The series, parallel, and overlapping structures of the ducts are ingeniously designed to optimize the airflow path and distribution, ensuring that the airflow fully impacts the generator blades. For example, parallel ducts increase the contact opportunities between the airflow and the blades, acting like multiple energy channels simultaneously delivering energy to the blades; overlapping ducts enhance the airflow energy density, carrying more concentrated energy with each impact on the blades. 2. Inlet and Outlet Design: The fan outlet is located inside the inlet, and the inlet cross-section is much larger than the fan diameter. This layout facilitates a siphon effect, overcoming duct resistance and increasing the kinetic energy of the air in the intake area, laying a good foundation for subsequent power generation. Classification by Duct Layout: 1. Type A Return-Flow Generator: Adapted to parallel and overlapping U-shaped ducts, utilizing the U-shaped path to allow the airflow to contact the blades multiple times, improving energy capture efficiency, suitable for small-scale distributed projects. 2. Swirl Generator Type B: Used in S-shaped ducts connected in series, the swirling flow generated by the S-shaped duct ensures more even and sustained stress on the blades, making it suitable for areas with stable wind speeds. 3. Composite Generator Type C: Suitable for complex duct systems containing multiple series, parallel, overlapping, recirculation, and swirling flows, integrating different airflows to improve the power and stability of large centralized air-powered power plants.

[0028] Modular generator design, with rotor diameter only 1 / 3-1 / 5 of traditional wind turbines. 1. Modular parallel duct wind turbine: Adopting a modular design, it is easy to install and maintain. Utilizing the parallel duct structure, airflow impacts the blades from multiple directions, effectively improving energy capture efficiency. 2. Modular recirculation and vortex duct wind turbine: Introducing recirculation and vortex design within the duct changes the way airflow impacts the blades, allowing the blades to receive airflow action more comprehensively at different angles and positions, enhancing the uniformity and continuity of blade stress, thereby improving power generation efficiency. 3. Two parallel double-overlapping duct wind turbine: Integrating parallel and overlapping designs, it further increases airflow energy and the number of interactions with the blades, significantly improving power generation. 4. Two parallel double-overlapping recirculation-vortex generator: Incorporating recirculation-vortex design on the basis of two parallel double-overlapping ducts, combining multiple advantages to comprehensively optimize power generation performance. 5. Two parallel triple-overlapping and multi-overlapping wind turbine: By increasing the number of overlapping layers, it further enhances airflow energy density and continuously improves power generation efficiency. Two-parallel triple-overlap and multi-overlap recirculation-vortex generators: Combining multi-overlap and recirculation-vortex designs, these generators deeply mine airflow energy to achieve high-efficiency power generation, reducing manufacturing costs and maintenance complexity. Installation and application of the recirculation-vortex generator: In a two-parallel duct design, the recirculation generator has a unique structure and operating mode. The generator is positioned in the middle of the duct, separating the two ducts and providing relative isolation and sealing. This allows the blades to be subjected to forces in both ducts simultaneously. When the airflow enters the duct, it impacts the blades, causing the first impact. When encountering a bend in the recirculation flow, the blades experience a second impact. As the airflow flows through the two parallel ducts, both sides of the blades are simultaneously subjected to the force of the airflow. This dual-sided force results in stronger and more balanced power for the blades, thus more efficiently driving the generator and effectively improving power generation efficiency.

[0029] Automatic power switching ensures stable system operation. 1. Wind speed stabilization principle and actual variation factors: Theoretically, based on the fluid continuity equation, the wind speed in the duct remains stable under specific conditions. However, in reality, duct wall friction, local disturbances, air viscosity and temperature changes, as well as the turbulent characteristics of the airflow affect wind speed stability. Duct wall friction reduces the air velocity near the wall, forming a boundary layer; disturbances from local components (such as generator blades, measuring instruments, etc.) change the local wind speed; changes in air viscosity and temperature cause energy loss and density changes, affecting wind speed; the turbulent characteristics of the airflow cause random velocity fluctuations. 2. Impact of wind speed changes on power generation system components: Reduced wind speed will decrease the generator speed, affecting power generation. At the same time, unstable wind speed will cause fluctuations in blade load, accelerating fatigue wear and shortening blade life. For other components in the duct, airflow pressure fluctuations caused by wind speed changes may lead to increased structural vibration, affecting structural safety and reliability. 3. Wind speed stabilization control strategy: An intelligent ventilation fan control system is adopted, which adjusts the fan speed or blade angle in real time based on feedback information from the wind speed sensor. Installing rectifiers, such as guide vanes and flow stabilizers, within the ductwork improves airflow characteristics. For large systems, multiple fans are used in conjunction with control, and operating parameters are coordinated based on wind speed at different locations within the duct to ensure stable wind speed and improve power generation efficiency and system stability.

[0030] In practical implementation, the ventilator is driven by an external power source or a diesel generator to generate initial airflow. 1. Principle of wind speed stability and actual variation factors: Theoretically, based on the fluid continuity equation, the wind speed in the duct remains stable under specific conditions. However, in reality, duct wall friction, local disturbances, air viscosity and temperature changes, as well as the turbulent characteristics of the airflow, affect wind speed stability. Duct wall friction reduces the air velocity near the wall, forming a boundary layer; disturbances from local components (such as generator blades, measuring instruments, etc.) alter local wind speed; changes in air viscosity and temperature cause energy loss and density changes, affecting wind speed; and the turbulent characteristics of the airflow lead to random velocity fluctuations.

[0031] The impact of wind speed variations on power generation system components: Decreased wind speed reduces generator speed, affecting power output. Unstable wind speeds cause fluctuations in blade load, accelerating fatigue wear and shortening blade life. For other components within the duct, airflow pressure fluctuations caused by wind speed changes can intensify structural vibrations, impacting structural safety and reliability. The airflow impacts the generator blades through optimized ductwork, and the power output is monitored by a formula-based intelligent control system, which automatically switches to airflow-based power generation. Wind speed stabilization control strategy: An intelligent ventilation fan control system is employed, adjusting fan speed or blade angle in real time based on feedback from wind speed sensors. Rectifying devices, such as guide vanes and flow-stabilizing grids, are installed within the duct to improve airflow characteristics. For large systems, multiple fans are used in coordinated control, with operating parameters adjusted according to wind speed at different locations within the duct to ensure wind speed stability and improve power generation efficiency and system stability.

[0032] Once the air-generating wind power system successfully enters a stable operating state, the power supply will automatically switch to the wind power source to maintain the normal operation of the power generation system. This automatic switching process is achieved by a meticulously designed intelligent control system. This system monitors key parameters in real time, such as the output power of the wind power generation system, voltage stability, and the operating status of the ventilation fan. Once the electrical energy generated by the wind power generation system meets the operating requirements of the ventilation fan and the entire power generation system, the intelligent control system reacts quickly, seamlessly switching to the wind power source through a specific circuit switching device, ensuring the continuous and stable operation of the system. This automatic switching mechanism not only improves the autonomy and sustainability of energy utilization, reduces dependence on external power sources, and lowers operating costs, but also demonstrates the intelligence and efficiency of new energy air power generation systems in energy management.

[0033] Stable airflow within the duct is maintained through wind speed sensors and fan speed regulation. The wind speed stabilization control strategy employs an intelligent fan control system that adjusts fan speed or blade angle in real time based on feedback from the wind speed sensors. Rectifying devices, such as guide vanes and flow-stabilizing grilles, are installed within the duct to improve airflow characteristics. For large systems, multiple fans are used in coordinated control, with operating parameters adjusted according to wind speed at different locations within the duct to ensure stable airflow, thereby improving power generation efficiency and system stability.

[0034] Wind speed stabilization principle and actual variation factors: Theoretically, based on the fluid continuity equation, the wind speed in a duct remains stable under specific conditions. However, in reality, duct wall friction, local disturbances, air viscosity and temperature changes, as well as the turbulent characteristics of the airflow, affect wind speed stability. Duct wall friction reduces the air velocity near the wall, forming a boundary layer; disturbances from local components (such as generator blades, measuring instruments, etc.) alter local wind speeds; changes in air viscosity and temperature cause energy loss and density changes, affecting wind speed; and the turbulent characteristics of the airflow lead to random velocity fluctuations. The impact of wind speed changes on power generation system components: Reduced wind speed decreases generator speed, affecting power output. Unstable wind speed also causes fluctuations in blade load, accelerating fatigue wear and shortening blade life. For other components within the duct, airflow pressure fluctuations caused by wind speed changes may lead to increased structural vibration, affecting structural safety and reliability. Wind speed stabilization control strategy: Employing an intelligent ventilation fan control system, adjusting the fan speed or blade angle in real time based on feedback from wind speed sensors. Installing flow straightening devices within the duct, such as guide vanes and flow stabilizers, improves airflow characteristics. For large-scale systems, multiple fans are used in coordinated control. Operating parameters are controlled in a coordinated manner based on wind speed at different locations within the duct to ensure stable wind speed and improve power generation efficiency and system stability. Training and personnel management: Tiered training covers basic knowledge, professional skills, and specialized training for management levels, with a continuous update mechanism to ensure personnel master technical and operational requirements. Personnel management: A comprehensive management system is established, including qualification certification, job responsibilities, performance evaluation, and emergency team building, ensuring the application of technical specifications and talent reserves. Cooling mode advantages: Utilizing a water-cooling mode, it offers advantages such as high cooling efficiency, stable temperature control, small footprint, good noise reduction, and reduced component wear, making it suitable for various scenarios.

[0035] This invention, by constructing an integrated "electricity consumption-generation-energy storage" model, enables enterprises to achieve efficient energy recycling, significantly reducing dependence on traditional energy sources, effectively cutting energy expenditures, and enhancing market competitiveness. In the civilian electricity sector, new energy air-powered generation technology means a more stable and reliable power supply. It breaks the limitations of traditional wind power generation imposed by natural conditions, eliminating reliance on weather conditions and enabling a continuous and stable supply of electricity to residents, improving the quality and stability of residential electricity use and bringing more convenience to daily life. In the fields of national security strategy and the military, the advantages of this technology are particularly prominent. Military operations have extremely high requirements for energy stability, autonomy, and confidentiality. The characteristic of new energy air-powered generation technology being unaffected by the natural environment ensures that military facilities and equipment can obtain stable power support under various complex and extreme conditions. This not only enhances the autonomy and flexibility of military operations but also provides a solid energy guarantee for national strategic security.
