[0002] In the field of wind resource development and utilization, efficient wind energy collection and convergence technology is of great significance to improving the overall efficiency of wind power generation systems. Traditional wind power generation equipment is mainly fixed horizontal axis or vertical axis wind turbines, and their operating performance is usually limited by wind direction, wind speed and installation environment. For example, horizontal axis wind turbines need to use complex adjustment mechanisms to capture the effective wind direction, which increases the structural complexity and operating cost of the equipment; while vertical axis wind turbines are less dependent on wind direction, but the wind-receiving area is small and the energy conversion efficiency is limited in low wind speed environments, making it difficult to adapt to diverse scenario requirements.

[0003] In addition, existing wind energy utilization equipment usually lacks flexible modular design, and its functions are mostly single-directional wind energy collection and conversion, making it difficult to achieve multi-directional guidance and efficient convergence of wind energy, especially in scenarios where wind energy needs to be transported from low to high or from high to low, the applicability of traditional equipment is insufficient. This limitation restricts the widespread application of wind energy in complex terrain, industrial plants and open areas. Summary of the invention

[0004] In order to solve at least one of the above problems, the present invention proposes a modular wind-collecting and guiding duct, which realizes the efficient capture and guided convergence of wind energy through innovative structural design. The duct is designed with a combination of rectangular curved blades and hollow air ducts, and utilizes a multi-section modular assembly method, which can flexibly adapt to different application scenarios, while realizing multi-level concentration and efficient conduction of wind energy. The one-way air intake and air guide design of the duct can effectively avoid airflow reflux losses and significantly improve the wind energy utilization rate of the equipment. Compared with traditional wind collection equipment, this invention not only performs well under breeze conditions, but also has wide application adaptability and convenient installation and maintenance characteristics, providing a new technical solution for the efficient utilization of wind energy resources.

The secondary blade is arranged at the root of the main blade and occupies about 1 / 2 of the area of ​​the main blade. The top plate and the bottom plate are respectively arranged at the upper and lower ends of the blade and the air duct; The wind tube can be used independently in a single section or in a modular vertical assembly of multiple sections.

[0006] Preferably, reinforcing ribs are provided at the connection between the main blade plate and the secondary blade plate of the blade to enhance the overall structural strength of the blade.

[0007] Preferably, the air collecting opening is in the shape of a rectangular strip to optimize the airflow entry efficiency.

[0014] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices or methods consistent with some aspects of the present application as detailed in the appended claims.

[0015] The modular wind-collecting and guiding wind tube of the present invention can efficiently collect and conduct wind energy, guide natural wind from low to high or high to low, and is suitable for wind power generation and other places where wind collection and convergence are required. The cylindrical design can adapt to wind from any wind direction and still has good wind collection performance under light wind conditions. The modular design and lightweight high-strength materials make it easy to install and flexible to use, and it has wide applicability and significant energy conversion efficiency.

[0016] For details, please refer to Figure 1 , Figure 2 As shown, the air duct 1 mainly includes four parts: a blade 11, an air duct 12, a top plate 13 and a bottom plate 14.

[0017] The blade 11 is a vertically set rectangular arc panel, the thickness of the panel is not less than 4mm, the height can be determined according to the specific application environment, generally not less than 1m, and the material is preferably a light and high-strength aluminum alloy; Figure 3It can be seen that the blade 11 is mainly composed of two parts: a main blade 111 and a secondary blade 112; the secondary blade 112 is arranged at the root of the main blade 111 and occupies 1 / 2 of the area of ​​the main blade 111, and forms an angle attack with the main blade 111, and the angle is about 5 to 8 degrees, so as to strengthen the plate strength of the main blade 111 and play a guiding role when collecting wind at the air outlet; the secondary blade 112 is consistent with the plate curvature of the main blade 111, and is preferably formed by plate rolling, welding or integral casting.

[0018] according to Figure 2 , Figure 4 It can be seen that the air duct 12 is a vertically set up cylindrical hollow tube, the height of the tube body is equal to the blade 11, and the thickness is not specifically limited by the present invention; a plurality of equidistant vertical air collecting ports 121 are arranged around the tube wall of the air duct 12, and the height of the air collecting ports 121 can be determined according to the specific application site, and the maximum is consistent with the height of the blade 11, and a one-way air inlet self-shrinking port is arranged at the air collecting port 121; the one-way air inlet self-shrinking port is a flexible silicone or rubber product, which automatically opens the one-way air inlet self-shrinking port when wind pressure enters, and wind energy enters the air duct 12 from the outside to the inside, and automatically closes the one-way air inlet self-shrinking port when there is no wind pressure, and the wind energy entering the air duct 12 will not flow back under the action of the one-way air inlet self-shrinking port.

[0019] The wind tube 1 is formed by a plurality of blades 11 arranged in an equidistant array around the air duct 12; the blades 11 are fixedly arranged on the tube walls on both sides of the air collecting port 121, and are preferably formed by an integrated molding process.

[0020] pass Figure 2 It can be known that the top plate 13 and the bottom plate 14 are respectively arranged at the upper and lower ends of the blade 11 and the air duct 12; the top plate 13 and the bottom plate 14 are flange plates with a certain thickness, and the material is aluminum alloy or steel plate. Fixing holes can be set on the edges of the flange plates to play a fastening role when assembling the multi-section air duct 1, or the flange plates between the multi-section air ducts can be connected by welding.

[0021] Furthermore, Figure 2 , Figure 4As shown, an upper air guide port 131 is provided at the center of the top plate 13, and a lower air guide port 141 is provided at the center of the bottom plate 14. The upper air guide port 131 and the lower air guide port 141 have the same structure and are both provided with the same one-way air guide self-shrinking port. The one-way air guide self-shrinking port has the same working principle as the one-way air intake self-shrinking port. When the wind energy internal pressure of the air duct 12 continues to increase and is greater than or equal to the internal equilibrium static pressure, the lower air guide port 141 automatically opens the one-way air guide self-shrinking port to conduct the wind energy collected by the air duct 12 to the wind duct of the lower group. When the multi-section wind duct 1 is assembled and used, the outer diameter, center and fixed holes of the wind duct 1 are aligned and reinforced to form an open circuit state for continuous convergence supply of pipeline-guided wind energy. This invention can guide the convergence of natural wind energy from low to high or high to low or ground, and is suitable for wind collection and power generation projects. At the same time, the present invention is also suitable for any place or factory building where wind collection and convergence are required, and the application range is very wide.

[0022] Furthermore, a preferred embodiment of the vertical assembly of the multi-section wind tube 1 is as follows: Flange sealing structure: The top plate 13 and the bottom plate 14 adopt a flange design with an annular sealing groove. A weather-resistant silicone sealing ring (thickness ≥ 6mm) is embedded in the sealing groove. During assembly, the upper and lower flanges are tightened by bolts to press the sealing ring to form an airtight connection; Double sealing of air guide port: the one-way air guide self-shrinking port of the upper air guide port 131 and the lower air guide port 141 adopts a double-layer silicone valve structure, the inner layer is a guide valve, and the outer layer is an annular sealing gasket. When the wind pressure is closed, the outer gasket fits tightly with the pipe wall, and the air leakage rate is less than 3%.

[0023] Modular assembly steps 1. Pre-assembly preparation: Check the integrity of the sealing ring of the single-section air duct 1 and clean the flange contact surface; The sealing ring is inserted into the annular groove of the top plate 13 to ensure that there is no distortion.

[0024] 2. Vertical docking: The upper air duct is hoisted so that the lower air guide port 141 of the bottom plate 14 is coaxially aligned with the upper air guide port 131 of the top plate 13 of the lower air duct; Temporarily fix through the bolt holes on the edge of the flange.

[0025] 3. Sealing and tightening: The bolts are tightened three times with increasing torque using the diagonal tightening method to compress the seal ring to 70% of its original thickness. The design uses the synergy of mechanical compression seal and double seal of air guide port, and the measured air leakage rate is only 1.8% at a wind speed of 15m / s, which is significantly higher than the 8-12% air leakage rate of the traditional flange connection method; and the modular assembly can complete the single-section docking within 20 minutes with the cooperation of 3 people, which is suitable for high-altitude operations.

[0026] In general, the overall shape of the wind tube 1 is cylindrical, which is suitable for collecting wind from any direction. Figure 1 As shown in the schematic diagram of wind force and direction in and out, the wind duct 1 collects wind energy from the outside to the inside, and the wind energy is guided upward or downward from the inside through the wind duct 12 for convergence, and is pressurized and transported layer by layer. The wind collection effect is still significant under breeze conditions; and the wind duct 1 can be fixedly installed or rotatably installed, can be used independently in a single section or assembled vertically in modularized units of multiple sections, and can also be used for long-distance convergence. The wind duct 1 of the present invention can also be expanded for horizontal installation, which greatly facilitates the convenience and flexibility of application.

For those skilled in the art, any equivalent modifications and substitutions made to the invention are also within the scope of the present invention. Therefore, the equalization changes and modifications made without departing from the spirit and scope of the present invention should be included in the scope of the present invention.
