Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, and in particular to a wind power generation device. Background Technology

[0002] Current wind power generation technology primarily relies on wind turbine blades to directly capture wind energy, and its energy conversion efficiency is significantly affected by factors such as wind speed and direction. Especially in areas with low wind speeds or unstable winds, traditional wind power generation devices have low efficiency, failing to meet practical needs. To improve wind power generation efficiency, various improvement methods have emerged, such as refining blade design and optimizing turbine layout. However, these methods still have limitations in improving efficiency. For example, blade design is limited by materials and manufacturing processes, making it difficult to achieve optimal aerodynamic characteristics; turbine layout is limited by space constraints, making it difficult to fully utilize wind energy resources. Some existing technologies attempt to increase wind speed at the turbine through wind concentrators, thereby improving power generation efficiency. However, most existing wind concentrators are complex in structure, costly, and have unsatisfactory wind concentration effects or suffer from wind energy losses, making it difficult to effectively improve overall power generation efficiency. Therefore, providing a wind power generation device with higher power generation efficiency is essential.

[0003] However, one of the shortcomings of the existing technologies is that they cannot concentrate wind efficiently, which reduces the efficiency of wind power generation. Utility Model Content

[0004] This utility model aims to solve at least one of the above-mentioned technical problems.

[0005] To address the aforementioned problems, the primary objective of this utility model is to provide a wind power generation device, comprising: a wind turbine; a generator connected to the wind turbine; and a wind concentrator connected to the wind turbine, wherein the wind concentrator is equipped with a wind collector.

[0006] Wind concentrators effectively gather dispersed wind energy and increase wind speed at the rotor, ensuring a certain level of power output even in low-wind-speed environments. By more effectively collecting and utilizing wind energy, the energy conversion efficiency of wind power generation devices is improved. If this design can effectively improve power generation efficiency, the required rotor size or number may be reduced for the same power output, thereby lowering manufacturing costs and floor space. The concentrator's design better guides surrounding air towards the concentrator, resulting in a more efficient wind energy conversion compared to devices that can only receive wind from the front.

[0007] In the above technical solution, the wind concentrator is equipped with a wind distribution device, and the two ends of the wind distribution device are connected to the wind turbine and the wind concentrator, respectively.

[0008] A wind distribution device can initially guide and distribute wind blowing from various directions, reducing airflow turbulence and making the airflow entering the wind turbine more uniform, thereby improving the efficiency of the wind turbine in converting wind energy into mechanical energy. Without a wind distribution device, wind enters the wind turbine directly, which may result in some areas having excessively high wind speeds and others having excessively low wind speeds, reducing overall efficiency. It plays a role in optimizing airflow, improving energy capture rate, and enhancing wind turbine operating efficiency, ultimately improving the performance of the entire wind power generation system.

[0009] In any of the above technical solutions, the air distribution device includes: an air distribution duct, the two ends of which are connected to the impeller and the wind concentrator; and an air distribution column, which is connected to the impeller.

[0010] The combination of the air distribution box and the air distribution column can direct the incoming air towards the guide vanes, further guiding the direction and speed of the airflow, optimizing the airflow distribution, and reducing dead zones and energy loss.

[0011] In any of the above technical solutions, the air distribution column is set as a curved surface structure.

[0012] Curved structures enable a smoother transition in airflow direction, reducing turbulence and energy loss during airflow turning. A cleverly designed curved structure can accelerate airflow using the Venturi effect, much like a nozzle. As airflow passes through the curved structure, its cross-sectional area decreases, its velocity increases, thereby increasing kinetic energy and ultimately enhancing the wind speed and energy entering the impeller.

[0013] In any of the above technical solutions, the air-gathering device is further provided with an air-gathering barrel, and the two ends of the air-gathering fan are respectively connected to the air-gathering barrel and the air-distributing device.

[0014] The concentrator acts like a conical nozzle, further converging and compressing the relatively dispersed airflow from the air distributor, significantly increasing airflow velocity and kinetic energy density. It reduces airflow turbulence and energy loss as the airflow approaches the concentrator. The concentrator provides a smoother transition, reducing airflow friction and energy loss. By optimizing the shape and size of the concentrator, it ensures that the airflow enters the concentrator at the optimal angle and velocity, improving the concentrator's efficiency.

[0015] In any of the above technical solutions, the wind turbine includes: a stationary rotor; a rotor connected to the stationary rotor, and the inner side of the rotor connected to a generator.

[0016] The fixed impeller directs the incoming airflow, changing the horizontal direction of the wind so that it directly hits the blades in the rotor, thus improving the efficiency of converting wind energy into mechanical energy. The separate design of the fixed and rotor impellers makes maintenance and component replacement easier. If a part fails, it can be replaced individually without replacing the entire rotor.

[0017] In any of the above technical solutions, the generator is equipped with a rotating shaft, which is connected to the inner side of the rotor.

[0018] As a key component for power transmission, the shaft reliably transmits the rotational motion of the rotor to the generator rotor. This direct mechanical connection ensures efficient energy transfer, avoiding energy loss and efficiency reduction associated with complex transmission mechanisms. This design allows the generator and rotor to be tightly integrated into a relatively compact structure, saving space and reducing manufacturing costs. Compared to complex transmission systems, this simple shaft connection simplifies generator design and maintenance, reduces failure rates, and improves system reliability. It also reduces the number of components requiring maintenance. Attached Figure Description

[0026] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other. Many specific details are set forth in the following description to provide a thorough understanding of this utility model; however, this utility model can also be implemented in other ways different from those described herein. Therefore, the scope of protection of this utility model is not limited to the specific embodiments disclosed below.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, an embodiment of this utility model provides a wind power generation device, which includes: a wind turbine 100; a generator 200 connected to the wind turbine 100; a wind concentrator 300 connected to the wind turbine 100, the wind concentrator 300 being equipped with a wind concentrator 310; the wind concentrator 300 being equipped with a wind distribution device 320, the wind distribution device 320 having two ends connected to the wind turbine 100 and the wind concentrator 310 respectively; the wind distribution device 320 includes a wind distribution hopper 321 and a wind distribution column 322, the wind distribution hopper 321 having two ends connected to... The wind turbine 100 and the wind concentrator 310 are connected together, and the wind distribution column 322 is connected to the wind turbine 100. The wind distribution column 322 is configured with a curved surface structure. The wind concentrator 300 is also provided with a wind concentrator 330. The two ends of the wind concentrator 310 are respectively connected to the wind concentrator 330 and the wind distribution device 320. The wind turbine 100 includes a fixed wheel 110 and a rotating wheel 120. The rotating wheel 120 is connected to the fixed wheel 110, and the inner side of the rotating wheel 120 is connected to the generator 200. The generator 200 is provided with a rotating shaft 210, and the rotating shaft 210 is connected to the inner side of the rotating wheel 120.

[0028] In this embodiment, the wind turbine 100 is provided with multiple fixed impellers 110 and multiple rotating impellers 120, with the rotating impellers 120 and fixed impellers 110 spaced apart to improve the utilization efficiency of wind energy. The wind distribution column 322 and the wind distribution barrel 321 form a wind duct, ensuring that the wind entering the wind concentrator 300 is directed to the blades of the wind turbine 100. A wind concentrator 310 is positioned between the wind concentrator 330 and the wind distribution device 320. The wind concentrator 310 is an electric fan that generates a certain amount of wind force when powered on. This wind force, in conjunction with the wind concentrator 330, can better attract surrounding airflow to the wind concentrator 300. Compared to the prior art, which can only receive wind blowing directly into the wind concentrator 300, the wind concentrator 310 significantly improves wind utilization. The right side diameter of the wind concentrator 330 is larger than the left side diameter to receive more wind and concentrate it towards the wind concentrator 310. The generator 200 is equipped with a rotating shaft 210, which is connected to the inner side of the wind turbine 100. When the wind turbine 100 rotates, it drives the rotating shaft 210 to rotate, thereby driving the rotor of the generator 200 to rotate, thus achieving the effect of converting mechanical energy into electrical energy. When using this wind power generation device, the wind collector 310 is energized, causing its inner blades to rotate and better absorb airflow. The airflow is blown from the wind collector 330 to the wind collector 310 and then guided by the wind distribution device 320 to the blades of the fixed wheel 110. The fixed wheel 110 changes the direction of the wind, causing it to blow directly onto the rotor 120, thereby driving the inner side of the rotor 120 to rotate. The rotation of the inner side of the rotor 120 will drive the rotating shaft 210 connected to it to rotate, thus making the generator 200 operate and achieving the effect of converting wind energy into electrical energy.
