Description

Technical Field

[0001] This invention belongs to the technical field of wind power generation devices and relates to a wind-collecting ducted wind turbine. Background Technology

[0002] Wind power generation is a method of generating electricity by converting wind turbines into electrical energy. Wind power is a widely distributed, free, clean, and renewable energy source with the advantages of maintaining environmental balance and improving energy efficiency. Conventional wind turbines typically use an L-shaped three-bladed horizontal axis generator installed at elevated locations. Specifically: ① The high-altitude installation of large-diameter three-bladed horizontal axis wind turbines increases the material consumption and cost of the base and tower due to the large overall height. The transport of the blades (extra-long components) is difficult and logistics costs are high. Furthermore, the high linear velocity of the rotating blade tips exposed to the natural environment during operation has a significant ecological impact on birds and other wildlife. ② The single-layer electrically driven variable-pitch three-bladed rotor has a small windward area, resulting in poor wind capture capacity and low wind energy utilization. ③ In severe weather conditions, a rigid protection method is generally used to force the large-diameter rotor blades to stop rotating using physical (generator electronic) brakes. Therefore, in severe weather conditions, the long blades and the electrically driven variable-pitch mechanism have poor self-protection capabilities and are easily damaged. Once damaged, repairs are time-consuming and costly. In summary, existing methods for generating wind power using conventional, high-altitude-mounted L-type three-bladed horizontal-axis wind turbines suffer from several drawbacks. These include high material consumption for the base and tower, high cost, difficulties and high logistics costs associated with transporting the long blades, significant ecological impact on birds and other wildlife, low wind energy utilization rates in single-layer electrically driven variable-pitch three-bladed turbines, and poor self-protection capabilities and high repair difficulty for the blades and electric-driven variable-pitch mechanism during severe weather. Therefore, addressing these issues—high material consumption for the base and tower, difficulties and high logistics costs associated with transporting the long blades, significant ecological impact on birds and other wildlife, low wind energy utilization rates in single-layer electrically driven variable-pitch three-bladed turbines, and poor self-protection capabilities and high repair difficulty for the blades and electric-driven variable-pitch mechanism during severe weather—is a crucial technical challenge that requires expertise in this field.

[0003] To address the above technical problems, this invention provides a wind-collecting ducted wind turbine.

[0004] To achieve the above objectives, the present invention provides the following solution: Specifically, a wind-gathering ducted wind turbine generator consists of an assembled wind-gathering guide fairing, an active protection ducted wind turbine generator unit, and a power transmission and active yaw correction device. The assembled wind-gathering guide fairing is assembled from a front flange, an arc-shaped support arm, and a wind-gathering block.

[0006] The air collection blocks utilize two different materials and molding processes to facilitate convenient transport: a flexible membrane structure and a rigid panel assembly. One method uses environmentally friendly, lightweight, flexible (waterproof and airtight) membrane material for one-time molding or multi-piece stitching and bonding. This flexible membrane structure air collection block is an interchangeable / universal size fan-shaped block. It is conveniently transported by multi-layer folding and packaging or by rolling and bundling the flexible air collection blocks. The other method uses lightweight / high-strength integrated aluminum honeycomb panels as the main material. The rigid panel assembly air collection block is an interchangeable / universal size isosceles trapezoidal block. The integrated aluminum honeycomb panel is evenly cut into small isosceles trapezoidal strips along the height of the isosceles trapezoidal block for easy packaging and transport. At the site, the small isosceles trapezoidal strips are seamlessly spliced ​​according to the mold to form a rigid panel assembly air collection block.

[0007] The T-shaped commutator is a bevel gear drive type, and the front input shaft, rear input shaft, and output shaft of the T-shaped commutator are each an independent drive shaft; the front input shaft and rear input shaft of the T-shaped commutator rotate in opposite directions, that is, the rotation direction of the front impeller is opposite to that of the rear impeller; the center of the duct of the ducted wind turbine nacelle is coaxial with the center of the front input shaft / rear input shaft of the T-shaped commutator and the center of the conical fairing; the output shaft of the T-shaped commutator is coaxial with the electric rotary support turntable, the input shaft of the generator, and the conductive slip ring; the left and right hinged double doors are symmetrically arranged and are driven independently by their corresponding geared motors; the outer surfaces of the left and right hinged double doors form an integral arc surface when fully closed.

[0009] This wind-collecting ducted wind turbine has two operating modes: operational and protective. The control unit calculates and analyzes the wind speed signal collected in real time by the wind direction / speed detection sensor via a signal cable. If the wind speed does not exceed the warning value, the entire unit enters the operational mode; if the wind speed exceeds the warning value, the entire unit enters the protective mode. The protective mode works as follows: First, the control unit controls the reduction motor via the corresponding connection cable III to close the hinged double doors until the machine stops at a predetermined position and remains locked. At this time, the hinged double doors close the rear lip of the duct at the back of the ducted wind turbine nacelle. The system is shut down. Simultaneously, supported and maintained by the electric slewing bearing turntable and tower, the control unit calculates and analyzes the wind direction signal collected in real-time by the wind direction / speed detection sensor via signal cable. The control unit controls the motor via connecting cable I to drive the active protection ducted wind turbine unit through the electric slewing bearing turntable, ensuring that one side of the arc formed by the closed hinged double doors aligns with the wind direction and maintains stable yaw correction rotation. At this time, the rotating components of the active protection ducted wind turbine unit enter a shutdown protection state, namely the generator, T-commutator, and front impeller. Both the rear impeller and the rear impeller stop rotating. Its operating mode is as follows: First, the control unit controls the reduction motor via the corresponding connecting cable III to drive the hinged double doors to open until they stop at the predetermined position and remain locked. At this time, the hinged double doors open the rear lip of the duct at the back of the ducted wind turbine nacelle. Simultaneously, supported and held by the electric slewing support turntable and the tower, the control unit calculates and analyzes the wind direction signal collected in real time by the wind direction / speed detection sensor via the signal cable. The control unit then controls the motor via connecting cable I to drive the active protection ducted wind turbine through the electric slewing support turntable. The power generation unit aligns the front of the ducted wind turbine nacelle with the wind direction and maintains stable yaw correction rotation. The airflow collection shroud collects / gathers the airflow, and under the combined action of the conical rectifier, the collected / gathered accelerated airflow passes through the arc-shaped protective net and is guided into the duct of the ducted wind turbine nacelle to drive the front impeller and rear impeller to drive the T-shaped commutator and generator to generate electricity. After the work is completed, the airflow passes through the protective net and is discharged. The power generated by the generator is connected to the control unit through connecting cable II for technical processing, and then connected to the power grid or other electrical loads through composite cable I, conductive slip ring, and composite cable II.

[0010] The present invention achieves the following technical effects compared to the prior art: This invention relates to a wind-gathering ducted wind turbine generator, comprising an assembled wind-gathering shroud, an active protection ducted wind turbine generator unit, and a power transmission and active yaw correction device. The umbrella-shaped assembled wind-gathering shroud significantly increases the wind-catching area of ​​the active protection ducted wind turbine generator unit. The use of continuous spiral multi-layered blades in the front / rear impeller achieves a larger windward area and higher wind energy utilization. The front / rear impeller within the duct converts energy into mechanical energy, which is output by a T-shaped commutator and transmitted to a generator installed in the tower space to generate electricity, thus improving the overall aerodynamic performance within the duct. The control unit uses the collected wind direction / ... The wind speed data is analyzed and judged in real time, and different operating modes are executed. In the protection operating mode, the hinged double doors are controlled to close the duct rear lip on the back of the ducted wind turbine nacelle. Then, the electric rotary support turntable is controlled to keep one side of the arc surface formed by the hinged double doors consistent with the wind direction and to maintain a stable yaw correction rotation. At this time, the generator, T-shaped commutator, front impeller, and rear impeller of the active protection ducted wind power generation unit are all stopped for protection. Arc-shaped protective nets and protective nets are set in the front lip of the duct and the rear lip of the duct on the back of the ducted wind turbine nacelle, respectively, to reduce the ecological impact on birds and animals.

[0011] Compared to the method of wind power generation using an L-shaped horizontal axis wind turbine with an exposed structure and a large-diameter three-bladed rotor, this invention provides a wind-gathering ducted wind turbine. The umbrella-shaped, assembled wind-gathering shroud significantly increases the wind-catching area of ​​the actively protected ducted wind turbine unit. The use of continuous spiral multi-layered blades for the front / rear impellers allows for a larger windward area while reducing the impeller diameter and increasing wind energy utilization. The front / rear impellers within the duct convert energy into mechanical energy, which is output by a T-shaped commutator and transmitted to a generator located within the tower space. The absence of generator shape and volumetric space occupancy within the duct results in optimized aerodynamic performance. The assembled wind-gathering shroud, external generator, and continuous spiral multi-layered blades reduce the overall height of the wind turbine, thereby reducing material consumption and cost savings for the base and tower. The continuous spiral multi-layered blades replace ultra-long, irregularly shaped blades, solving problems related to wind farm site selection, transportation difficulties, and high logistics costs. The control unit... The collected wind direction / speed data is analyzed and judged in real time, and different operating modes are executed. In the protection operating mode, the hinged double doors are controlled to close the duct rear lip on the back of the ducted wind turbine nacelle. Then, the electric rotary support turntable is controlled to keep one side of the arc surface formed by the hinged double doors consistent with the wind direction and to maintain stable yaw correction rotation. At this time, the generator, T-shaped commutator, front impeller, and rear impeller of the active protection ducted wind power generation unit are all stopped for protection. During the active protection process, the back of the assembled wind collection guide is protected. The windward, i.e., the outer arc surface of the umbrella-shaped structure, provides protection for the assembled wind-gathering guide cover itself. Arc-shaped protective nets and protective nets are installed inside the front lip of the duct and the rear lip of the duct on the back of the ducted wind turbine nacelle, respectively, to reduce the ecological impact on birds and animals. At the same time, the assembled wind-gathering guide cover can improve the low-wind-speed start-up performance of the active protection type ducted wind power generation unit by guiding and gathering turbulent airflows, which can more effectively reduce the emission of greenhouse gases such as carbon dioxide, thus benefiting environmental protection and sustainable development.
