Description

Technical Field

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

[0002] The national "Thousands of Villages and Towns Wind Power Development Plan" for distributed wind power generation has been implemented for many years, but currently only photovoltaic power generation is truly being implemented. Wind power generation can only be implemented in high mountains and remote seas, and is almost impossible or unfeasible in vast rural areas, cities, grasslands, factory rooftops, and other similar scenarios. This is because most wind turbine blades are currently directly suspended in the air. While the turbine blades are propelled by the wind to rotate and do work, the turbine's rotation is also subject to wind resistance. The only way to minimize this resistance is to modify the shape of the turbine blades. Furthermore, the airflow propelling the turbine is limited to the airflow within the area swept by the turbine blades, resulting in limited mechanical energy. The airflow speed is simply the natural wind speed. At low wind speeds, the turbine cannot rotate or rotates very slowly. Some patents have considered designing ducts or wind deflectors to increase the wind volume, but it's impossible to make the entire duct follow the wind direction or to enlarge the wind deflector area. To increase power generation, the turbine blades must be infinitely enlarged, leading to increased technical difficulty, higher construction costs, and greater environmental and safety hazards. These technical problems are the reason why the power generation efficiency of wind power equipment used in thousands of villages and cities is generally too low. Not only is it not worth investing in, but it also generates noise, which can easily harm insects and birds, and even affect human safety. As a result, it is difficult to promote it in vast urban and rural areas, and the huge wind resources cannot be effectively utilized.

[0003] Therefore, existing technologies need to be improved and enhanced. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a wind turbine wind guide device that integrates a turbine internally, isolating the turbine from direct contact with natural kinetic wind. This eliminates the resistance of natural kinetic wind to turbine rotation and guides the wind force accelerated by the wind guide device into a couple, forming a torque to drive the turbine to rotate efficiently. This application focuses on the economic and environmental benefits of power generation, the elimination and suppression of operating noise, and the protection of insects and birds, truly complying with national wind power generation policies and bringing tangible economic and environmental benefits to businesses and households.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A wind turbine wind guide device, comprising A wind-guiding device body has an outer shell, an inner shell disposed within the outer shell, and a turbine rotatably mounted within the inner shell. A first annular inner cavity is formed between the outer shell and the inner shell, and a second annular inner cavity is formed between the inner shell and the turbine. A first vortex nozzle is disposed between the first annular inner cavity and the second annular inner cavity, and a second vortex nozzle is disposed in the second annular inner cavity. The first vortex nozzle and the second vortex nozzle are symmetrically arranged.

[0006] As a further embodiment of the present invention, the turbine includes a turbine body, which is rotatably mounted on the outer casing via a turbine shaft, and the outer circumferential surface of the turbine body is provided with a plurality of vortex blades.

[0007] As a further embodiment of the present invention, some of the vortex blades are curved, with their concave surfaces facing the airflow direction.

[0008] As a further embodiment of the present invention, the first vortex nozzle and the second vortex nozzle are symmetrically arranged about the vortex rotation axis.

[0009] As a further embodiment of the present invention, the first annular inner cavity is connected to the first air inlet channel, the first air inlet channel having a first air inlet, the second annular inner cavity is connected to the second air inlet channel, the second air inlet channel having a second air inlet, and the first air inlet channel and the second air inlet channel are arranged side by side.

[0010] As a further embodiment of the present invention, the first annular inner cavity and the second annular inner cavity share a common air outlet.

[0011] As a further embodiment of the present invention, the air outlet is located at the top of the outer casing.

[0012] As a further embodiment of the present invention, the first air inlet channel and the second air inlet channel are provided on one side of the outer casing.

[0013] As a further embodiment of the present invention, the air guide device body is mounted on a support frame.

[0014] Compared with the prior art, the beneficial effects of the present invention are: Due to the aforementioned structural design, high-speed airflow is ejected through the first and second vortex nozzles and acts on the turbine, forming a couple on the turbine. The torque of this couple causes the turbine to rotate at high speed, generating powerful torque, resulting in quieter and more stable operation. This application achieves a quiet operation through the built-in high-speed rotating turbine, and its absence of rotating blades prevents harm to birds and insects, making it environmentally friendly and increasing safety.

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Example

[0021] like Figure 1-3 As shown, this application discloses a wind-guiding device for wind power generation, comprising: A wind-guiding device body includes an outer shell 100, an inner shell 200 disposed within the outer shell 100, and a turbine 300 rotatably mounted within the inner shell 200. The outer shell is an open-end hollow cylinder with outer end caps covering both ends of the outer hollow cylinder. The inner shell is an open-end hollow cylinder with its two ends welded to the two outer end caps of the outer shell. A first annular inner cavity 400 is formed between the outer shell 100 and the inner shell 200. The inner shell 200 and the turbine 300 are connected... A second annular inner cavity 500 is formed. A first vortex nozzle 401 is disposed between the first annular inner cavity 400 and the second annular inner cavity 500. The second annular inner cavity 500 has a second vortex nozzle 501. The first vortex nozzle 401 and the second vortex nozzle 501 are symmetrically arranged. Through the above structural design, high-speed airflow is ejected through the first vortex nozzle and the second vortex nozzle and acts on the turbine, forming a couple on the turbine. The couple torque causes the turbine to rotate at high speed, generating strong torque, resulting in quieter and more stable operation. Compared with the torque of a single force, the couple torque avoids the bearing wear, noise, speed reduction, torque reduction, and impact on power generation efficiency caused by the side pressure that may be generated by a single force. This application achieves a quiet effect by incorporating a high-speed rotating turbine, and since there are no rotating blades on the outside, it will not harm birds or insects, making it very environmentally friendly and increasing safety.

[0022] Specifically, the turbine 300 includes a turbine body 301, which is rotatably mounted on the outer casing 100 via a turbine shaft 302. Both ends of the turbine shaft are rotatably mounted on the outer casing via bearings. The outer circumferential surface of the turbine body 301 is provided with a plurality of vortex blades 303, which are curved with their concave surfaces facing the airflow direction. The first vortex nozzle 401 and the second vortex nozzle 501 are symmetrically arranged about the vortex shaft 302. The two streams of airflow ejected from the first and second vortex nozzles that impact the turbine blades are equivalent to forming a pair of force couples on the turbine blades, that is, two forces of equal magnitude, opposite direction, and parallel but not collinear lines of action. The high-speed fluid with kinetic energy ejected from the two vortex nozzles can be efficiently converted into mechanical energy. Compared with single-sided injection, the symmetrical arrangement of the two nozzles can make fuller use of fluid energy and reduce energy loss.

[0023] Specifically, the first annular inner cavity 400 is connected to the first air inlet channel 600, and the first air inlet channel 600 has a first air inlet 601. The second annular inner cavity 500 is connected to the second air inlet channel 700, and the second air inlet channel 700 has a second air inlet 701. The first air inlet channel 600 and the second air inlet channel 700 are arranged side by side. The first air inlet channel and the second air inlet channel are connected to the bottom outlet of the airflow adapter of the wind power generation wind induced draft device. The upper inlet of the airflow adapter is a circular inlet, and the bottom outlet is a square outlet. The hollow inner cavity of the airflow adapter transitions the circular inlet cross section to a square outlet cross section.

[0024] Specifically, the first annular inner cavity 400 and the second annular inner cavity 500 share an air outlet 400a, which is located at the upper part of the outer shell 100. The first air inlet channel and the second air inlet channel are located on the side of the outer shell 100 near the air outlet 400a.

[0025] Specifically, the air guide device body is mounted on the support frame 800 to support the air guide device body.

[0026] In summary, the present invention, through the above-described structural design, overcomes the shortcomings of the prior art and features a reasonable structure, economic and environmental protection, and low noise.
