Description

Technical Field

[0001] This utility model relates to wind power generation, specifically to a wind power generation device with embedded turbine blades. Background Technology

[0002] With the increasing global demand for clean energy, wind power has received widespread attention as an important renewable energy source. Currently, wind power equipment is mostly deployed in areas far from cities, while wind resources in urban areas cannot be effectively utilized. Deploying traditional wind power equipment in cities presents several limitations:

[0003] 1) The blades of traditional wind power generation equipment generate loud noise when they are running, which disturbs the lives of nearby residents;

[0004] 2) When the blades are rotating at high speed, they may collide with flying birds, causing bird injuries or death and disrupting the ecological balance;

[0005] 3) Traditional wind power equipment occupies a large area, and the limited area in cities makes it difficult to deploy on a large scale. Moreover, the average wind speed in cities is relatively low, generally less than 4 m / s. Under such wind speed conditions, the efficiency of traditional wind power equipment will drop significantly, and it will not be able to fully realize its power generation capacity.

[0006] Therefore, developing a new type of wind power generation device that is adapted to the urban environment is of great practical significance. Utility Model Content

[0068] Compared with the prior art, the beneficial effects of this utility model are:

[0069] (1) The wind power generation device with embedded turbine blades provided by this utility model, when the wind passes through the hollow wind energy collection column, will form a negative pressure zone on its leeward side according to Bernoulli's principle, and the wind is gathered by the wind-collecting seat. The wind entering from the side opening of the wind-collecting seat will be sucked into the air duct due to the existence of the negative pressure zone. The wind speed in the air duct can be increased by 1.4-2 times. At this time, the turbine blades will be driven to rotate, which in turn drives the generator to rotate and generate electricity. Because of the embedded turbine blade design, the risk of bird strikes is prevented. Compared with the huge noise generated when the huge blades of traditional wind power generation equipment rotate, the turbine blades have low operating noise. In particular, the power generation is greater when wind power is generated by combining N turbine blade units. The overall structure is compact and occupies a small area.

By combining the hollow wind energy collection column and the air duct, the airflow is optimized and the starting wind speed of the generator is reduced, which can effectively utilize the low-speed wind resources in the city.

[0070] (2) The wind power generation device with embedded turbine blades provided by this utility model sets one end of the wind duct in the shape of a horn, which has a certain wind gathering effect. The mounting frame includes a top plate and multiple support columns set at the bottom of the top plate. Compared with the wind duct seat, the structure is simple and the maintenance is convenient.

[0071] (3) The wind power generation device with embedded turbine blades provided by this utility model has a front wind vane set at the upper edge of the wind sink to improve the airflow at the windward side of the lower end of the hollow wind energy collection column, and a rear wind vane set to improve the airflow at the leeward side of the lower end of the hollow wind energy collection column, which is conducive to the formation of a negative pressure zone and accelerates the wind speed in the wind duct.

[0072] (4) The height of the hollow wind energy collection column of the wind power generation device with embedded turbine blades provided by this utility model is determined according to the following principle: the angle between the airflow direction of the wind rising from the duct at the highest point of the hollow wind energy collection column and the vertical direction is not greater than 30°, because the wind energy collection efficiency decreases when it is greater than 30°.

[0073] (5) The wind power generation device with embedded turbine blades provided by this utility model has multiple guide plates on the outer wall of the hollow wind energy collection column. On the one hand, the guide plates can rectify the wind and make the wind pass through the hollow wind energy collection column more evenly. On the other hand, the guide plates can also strengthen the structure of the hollow wind energy collection column and improve its rigidity.

[0074] (6) When the wind turbine blade wind power generation device provided by this utility model has an arc-shaped cavity structure, it can still generate electricity with high efficiency when the wind direction changes slightly.

[0075] (7) The wind power generation device with embedded turbine blades provided by this utility model adopts a wind-collecting column for air intake and installs the turbine blades inside the wind-collecting column. The wind-collecting column has the same structure as the hollow wind energy collection column, and batch processing can save processing costs. Attached Figure Description

[0108] The present invention will be further described below with reference to the accompanying drawings and exemplary embodiments.

[0109] Example 1:

[0110] Reference Figures 1-7 This utility model discloses a wind power generation device with embedded turbine blades, comprising a wind-collecting unit, a hollow wind energy collection column 3, turbine blades, and a generator. The wind-collecting unit provides airflow to the hollow wind energy collection column 3. In this embodiment, the wind-collecting unit includes a wind-collecting seat 1 and a guide pipe 2. The structure of the wind-collecting seat 1 is as follows: Figure 1 , Figure 2 As shown, it is a cavity structure with a side opening, which can be a polygonal cavity structure or an arc-shaped cavity structure. For ease of manufacturing, this embodiment adopts a rectangular cavity structure in the polygonal cavity structure, with its side opening set on the windward side, so that the wind can be gathered into the wind-collecting seat 1.

[0111] And air duct 2, as Figure 2 As shown, it is a cylindrical structure and is installed on the inner top surface of the wind-collecting seat 1 in a vertical direction. The turbine blades are coaxially rotated and installed in the air guide pipe 2. The generator and the turbine blades are coaxially connected in the air guide pipe 2. This connection method is simple. If the space inside the air guide pipe 2 is insufficient to install the generator, the generator and the turbine blades can be connected by transmission shaft outside the air guide pipe 2.

[0112] The turbine blades use the NACA-4415 airfoil with a chord length c. i Distribution according to formula

[0113]

[0114] Where: C Li Ф is the lift coefficient. i r is the airflow tilt angle. i Let a be the radius of the i-th section of the turbine blade. i Let be the axial induction factor for the i-th cross section, and B be the number of turbine blades.

[0115] Furthermore, the angle of attack of the turbine blades decreases from 8° at the root to 4° at the tip.

[0116] The hollow wind energy collection column 3 used to form the negative pressure zone has a curved windward surface, which is made of a concave arc plate or a folded plate. When it is made of a concave arc plate, its cross-section can be C-shaped, U-shaped or semi-circular. When it is made of a concave folded plate, its cross-section is V-shaped.

[0117] The hollow wind energy collection column 3 can be set at the top or bottom of the wind-collecting unit. In this embodiment, it is installed on the outer top surface of the wind-collecting seat 1 in a vertical direction, and its lower end is connected to the upper end of the air guide pipe 2. In this way, after the wind passes through the windward side of the hollow wind energy collection column 3, a negative pressure zone will be formed on the leeward side due to Bernoulli's principle. The wind gathered by the wind-collecting seat 1 will be sucked into the air guide pipe 2 due to the existence of the negative pressure zone and then flow out from the hollow wind energy collection column 3. Its wind speed increases by 1.4-2 times, which drives the turbine blades to rotate. The turbine blades then drive the generator to rotate to complete the power generation.

[0118] Alternatively, the air duct 2 has the same structure as the air duct 2 mentioned above, but it is installed on the outer top surface of the wind-collecting seat 1 in a vertical direction, and the hollow wind energy collection column 3 is installed on the outer top surface of the wind-collecting seat 1 in a vertical direction, and the air duct 2 is located inside the hollow wind energy collection column 3, with the lower ends of both the air duct 2 and the hollow wind energy collection column 3 connected to the wind-collecting seat 1.

[0119] To facilitate the formation of a negative pressure zone, a front guide vane 4 and / or a rear guide vane 5 are provided along the upper edge of the air intake 1. The front guide vane 4 is inclined downwards at an angle of 0-30°. Figure 6 and Figure 7 The comparison shows that it improves the airflow at the windward end of the hollow wind energy collection column 3, which is conducive to the formation of a negative pressure zone and can increase the airflow velocity in the air guide duct 2; while the wind guide 5 improves the airflow at the leeward end of the hollow wind energy collection column 3, and it is also tilted downward with an inclination angle of 0-40°.

[0120] During wind tunnel simulation testing of the hollow wind energy harvesting column 3, the following results were obtained: Figure 3 , Figure 4 The cross section showing the wind speed CFD verification flow field distribution is shown. Figure 1 CFD verification of flow field distribution cross section with wind speed Figure 2 It was found that when the angle between the airflow direction and the vertical direction at the highest point of the hollow wind energy collection column 3 is greater than 30°, the wind energy collection efficiency decreases. Therefore, the following principles should be followed when determining the height of the hollow wind energy collection column 3:

[0121] The angle between the airflow direction at the highest point of the hollow wind energy collection column 3 and the vertical direction is no greater than 30°.

[0122] In this embodiment, the height of the hollow wind energy collection column 3 is 2500±200mm, the height of the air duct 2 is 250-600mm, and the diameter of the air duct 2 is 700±200mm.

[0123] To ensure more even wind distribution through the hollow wind energy collection column 3, multiple guide vanes 6 are installed on its outer wall. These guide vanes 6 are positioned along the height of the column 3 and are perpendicular to this height. This rectifies the airflow as it passes through the guide vanes 6, resulting in a more uniform distribution. Furthermore, the guide vanes 6 act as reinforcing ribs, structurally strengthening the hollow wind energy collection column 3 and improving its rigidity.

[0124] Depend on Figure 5 and Figure 6 It can be seen that the wind accelerates, converges, and flows in terms of magnitude and direction. However, the wind direction in the urban environment is constantly changing. To adapt to the changing wind direction, the hollow wind energy collection column 3 and the air guide duct 2 are connected to the wind-collecting seat 1 through bearings. In this way, the windward side of the hollow wind energy collection column 3 can rotate to adapt to the wind direction. In order to ensure that the wind-gathering efficiency of the wind-collecting seat 1 does not decrease in an environment with constantly changing wind direction, a base is set below the wind-collecting seat 1. The bottom of the wind-collecting seat 1 is rotatably connected to the base through bearings. In this way, the entire wind-collecting seat 1 can rotate, so that the side opening of the wind-collecting seat 1 can be adjusted to face the wind direction, thereby ensuring the wind-gathering efficiency. A wind vane is set on the hollow wind energy collection column 3 or the wind-collecting seat 1 to detect the wind direction. The wind-collecting seat 1 can be adjusted according to the indication of the wind vane.

[0125] pass Figure 7 and Figure 6 The comparison shows that after adding the front wind vane 4, the airflow is accelerated when it flows through the windward part at the lower end of the hollow wind energy collection column 3.

[0126] Example 2:

[0127] Reference Figure 8 The wind power generation device with embedded turbine blades in this embodiment includes a wind scooping unit, a hollow wind energy collection column 3, a turbine blade, and a generator. The hollow wind energy collection column 3 can be set at the top or bottom of the wind scooping unit. In this embodiment, the wind scooping unit includes a mounting frame 7 and a wind duct 2. The structure of the hollow wind energy collection column 3 is the same as that in Embodiment 1. Multiple guide plates 6 can also be set on it, which will not be described in detail here.

[0128] The mounting frame 7 includes a top plate and multiple support columns set at the bottom of the top plate. Unlike the wind-collecting seat 1 in Embodiment 1, the mounting frame 7 only serves a supporting function and no longer serves to concentrate the wind. At this time, the function of concentrating the wind is undertaken by the air guide duct 2. The air guide duct 2 is different from the air guide duct 2 in Embodiment 1 in that it is a right-angle, acute-angle or obtuse-angle bent pipe structure. In order to achieve the best wind-concentrating effect, a right-angle bent pipe structure is adopted in this embodiment. One end of it is installed at the bottom of the top plate of the mounting frame 7, while the hollow wind energy collection column 3 is installed vertically on the outer top surface of the top plate of the mounting frame 7, and its lower end is connected to one end of the air guide duct 2. In order to concentrate the wind, the other end of the air guide duct 2 is flared to increase the air intake area and play a certain role in concentrating the wind.

[0129] The turbine blades are rotatably installed inside the air duct 2. The generator and the turbine blades are coaxially connected inside the air duct 2 or driven by transmission outside the air duct 2. The structure of the turbine blades is the same as in Embodiment 1, and will not be described again here.

[0130] The hollow wind energy collection column 3 and the air guide pipe 2 are connected to the top plate through bearings. A base can also be set at the bottom of the mounting frame 7. The mounting frame 7 and the base are rotatably connected through bearings. This allows the orientation of the windward side of the hollow wind energy collection column 3 and the flared end of the air guide pipe 2 to be adjusted in real time according to the wind direction, so that the windward side of the hollow wind energy collection column 3 and the flared end of the air guide pipe 2 are always facing the wind, improving power generation efficiency. A wind vane can also be set on the hollow wind energy collection column 3 or the mounting frame 7 to monitor the wind direction.

[0131] The windward side of the top plate tilts downward to form the front wind vane 4, with the same tilt angle as in Embodiment 1, which is 0-30°. The leeward side of the top plate also tilts downward to form the rear wind vane 5, with a tilt angle of 0-40°. The functions of the front wind vane 4 and the rear wind vane 5 in this embodiment are the same as in Embodiment 1, and will not be repeated here.

[0132] Compared to Example 1, the structure in Example 2 has lower processing costs and is easier to maintain.

[0133] Example 3:

[0134] like Figure 9 As shown, in this embodiment, the duct unit still includes a duct seat 1 and an air duct 2, and the duct seat 1 is also a cavity structure with a side opening.

[0135] The installation position of the air duct 2 is different from that in Embodiment 1. Although the air duct 2 is still a cylindrical structure, it is installed horizontally at the side opening of the wind-collecting seat 1, while the hollow wind energy collection column 3 is still installed vertically on the outer top surface of the wind-collecting seat 1, and the hollow wind energy collection column 3 is connected to the wind-collecting seat 1.

[0136] The structure of the turbine blades and the hollow wind energy collection column 3 is the same as in Embodiment 1, and will not be described in detail here. Multiple guide vanes 6 can also be set on the hollow wind energy collection column 3 for rectification. A base can also be set at the bottom of the wind-catching seat 1. The bottom of the wind-catching seat 1 and the base are rotatably connected by bearings. This allows the windward surface of the hollow wind energy collection column 3 to be adjusted in real time according to the wind direction. A wind vane can also be set on the hollow wind energy collection column 3 or the wind-catching seat 1 for monitoring the wind direction.

[0137] A front guide vane 4 and / or a rear guide vane 5 are provided at the upper edge of the plenum seat 1. Their structure and function are the same as those in Embodiment 1, and will not be described again here.

[0138] The turbine blades are still coaxially mounted inside the air duct 2. The generator and turbine blades are coaxially connected inside the air duct 2 or connected by transmission outside the air duct 2. The above two installation methods can be selected according to the actual situation.

[0139] Example 4:

[0140] like Figure 10 As shown, in this embodiment, the duct unit still includes a duct seat 1 and a duct 2, but the duct seat 1 is a hollow structure with no openings on its side.

[0141] The structure of the hollow wind energy collection column 3 is the same as that in Embodiment 1, and will not be described again here. Multiple guide plates 6 can also be set on it for rectification. A base can also be set at the bottom of the wind-collecting seat 1. The bottom of the wind-collecting seat 1 and the base are rotatably connected by bearings. This allows the windward surface of the hollow wind energy collection column 3 to be adjusted in real time according to the wind direction. A wind vane can also be set on the hollow wind energy collection column 3 or the wind-collecting seat 1 to monitor the wind direction.

[0142] In this embodiment, the air duct 2 is a cylindrical structure and is installed on the inner top surface of the wind-collecting seat 1. A wind deflector 8 is provided at the outer port of the air duct 2. The wind deflector 8 is a quarter-spherical shell structure, and its opening faces the same direction as the windward side of the hollow wind energy collection column 3. In this way, when the wind flows through the wind deflector 8, it will be blocked and guided into the air duct 2.

[0143] The hollow wind energy collection column 3 is installed vertically on the outer top surface of the wind-collecting base 1, and the hollow wind energy collection column 3 is connected to the wind-collecting base 1. In order to ensure that the air intake of the air guide duct 2 is not affected, the air guide duct 2 is located in front of the hollow wind energy collection column 3.

[0144] A front guide vane 4 and / or a rear guide vane 5 are provided at the upper edge of the plenum seat 1. Their structure and function are the same as those in Embodiment 1, and will not be described again here.

[0145] The turbine blades are still coaxially mounted inside the air duct 2. The structure of the turbine blades is the same as in Embodiment 1, and will not be described again here.

[0146] The generator and turbine blades are coaxially connected inside the air duct 2 or connected by transmission outside the air duct 2. The specific connection method can be selected according to the actual situation.

[0147] Example 5:

[0148] Reference Figures 11-28 The wind power generation device with embedded turbine blades of this utility model includes a wind scooping unit, N turbine blade units and M generators, where N≥2 and 1≤M≤N.

[0149] Each turbine blade unit includes a hollow wind energy harvesting column 3 and turbine blades, with a wind-catching unit used to provide airflow to the turbine blades.

[0150] In this embodiment, the wind-collecting unit includes a wind-collecting seat 1 and N air guide pipes 2. The wind-collecting seat 1 is a hollow structure with a side opening, and the side opening is located on the windward surface. N hollow wind energy collection columns 3 are installed on the top or bottom of the wind-collecting unit and are spaced apart.

[0151] In this embodiment, as Figure 12 As shown, the air duct 2 is a cylindrical structure. N air ducts 2 are spaced apart along the side opening of the wind-collecting seat 1 and installed vertically on the inner top surface of the wind-collecting seat 1. N hollow wind energy collection columns 3 are spaced apart along the side opening of the wind-collecting seat 1 and installed vertically on the outer top surface of the wind-collecting seat 1. The lower ends of the N hollow wind energy collection columns 3 are connected to the upper ends of the corresponding N air ducts 2.

[0152] Alternatively, the air duct 2 is a cylindrical structure, with N air ducts 2 spaced apart along the side opening of the wind-collecting seat 1, but installed vertically on the outer top surface of the wind-collecting seat 1. N hollow wind energy collection columns 3 are also spaced apart along the side opening of the wind-collecting seat 1, and installed vertically on the outer top surface of the wind-collecting seat 1. The N air ducts 2 are respectively located inside the N hollow wind energy collection columns 3, and the lower ends of the air ducts 2 and the hollow wind energy collection columns 3 are connected to the wind-collecting seat 1.

[0153] The hollow wind energy collection column 3 has a curved windward surface, which can be made of a concave arc plate or a folded plate. When it is made of a concave arc plate, its cross-section is C-shaped, U-shaped or semi-circular; when it is made of a concave folded plate, its cross-section is V-shaped. Because of its shape, when the wind blows across the hollow wind energy collection column 3, a negative pressure zone will be formed on its leeward side according to Bernoulli's principle and Venturi effect.

[0154] N hollow wind energy collection columns 3 are spaced apart along the side opening of the wind-collecting base 1. The ratio of the distance between the outer edges of adjacent hollow wind energy collection columns 3 to the width of the hollow wind energy collection column 3 is 30%-60%. To adapt to changes in wind direction and achieve better power generation efficiency, the hollow wind energy collection columns 3 and the air guide pipe 2 are connected to the wind-collecting base 1 through bearings. Wind vanes are installed on the hollow wind energy collection columns 3 or the wind-collecting base 1 to detect the wind direction. The hollow wind energy collection columns 3 can be rotated according to the wind direction so that the windward side of the hollow wind energy collection column 3 faces the wind.

[0155] The turbine blades are coaxially mounted inside the air duct 2, and N turbine blades drive M generators to rotate. The turbine blade structure is the same as in Embodiment 1.

[0156] The correspondence between the turbine blades and the generator can be determined according to the actual situation. The generator can be coaxially connected to the turbine blades inside the air duct 2, which is suitable when there is enough space inside the air duct 2. If not, a coaxial connection can be used outside the air duct 2. Alternatively, a drive shaft can be used to transmit the rotation of the turbine blades to the outside of the air duct 2, so that the generator is connected to the turbine blades outside the air duct 2. In this case, multiple turbine blades can drive one generator, resulting in greater power generation and higher cost-effectiveness, achieving the effect of driving M generators with N turbine blades.

[0157] The 1-inch coupe seat has three structural forms, the first of which is as follows: Figure 11 , Figure 12 As shown, the first type is a polygonal cavity structure. In this embodiment, a rectangular cavity structure is used for ease of fabrication; the second type is... Figure 13 , Figure 14 As shown, the first type is an arc-shaped cavity structure with a convex arc-shaped windward surface; the third type is... Figure 15 , Figure 16 As shown, it has an arc-shaped cavity structure, and the windward side is an inwardly concave arc shape.

[0158] When the wind-collecting base 1 is a rectangular cavity structure, the angle A between the windward surface of the N hollow wind energy collection columns 3 and the direction in which the opening of the wind-collecting base 1 faces is 0°. Alternatively, among the N hollow wind energy collection columns 3, the angle A of the central hollow wind energy collection column 3 is 0°, and the angle A of the adjacent hollow wind energy collection columns 3 deviates from 0° to 15° to the sides respectively. When the wind direction changes slightly, the windward surface of some hollow wind energy collection columns 3 still faces the wind direction, which can generate electricity with high efficiency.

[0159] When the wind-collecting base 1 is an arc-shaped hollow structure with an outwardly convex arc-shaped windward surface, the normals of the windward surfaces of the N hollow wind energy collection columns 3 point to the center of the outwardly convex arc. When the wind-collecting base 1 is an arc-shaped hollow structure with an inwardly concave arc-shaped windward surface, the normals of the windward surfaces of the N hollow wind energy collection columns 3 point to the center of the inwardly concave arc, ensuring that even with slight changes in wind direction, some of the hollow wind energy collection columns 3 can still maintain high-efficiency power generation.

[0160] To facilitate the formation of a negative pressure zone, a front guide vane 4 is provided at the upper edge of the side opening of the wind-collecting base 1. The front guide vane 4 is inclined downwards at an angle of 0-30°. A rear guide vane 5 is provided at the upper edge of the leeward side of the wind-collecting base 1. The rear guide vane 5 is inclined downwards at an angle of 0-40°. The front guide vane 4 is used to improve airflow at the windward side of the lower end of the hollow wind energy collection column 3, while the rear guide vane 5 is used to improve airflow at the leeward side of the lower end of the hollow wind energy collection column 3. Figures 17-20 It can be seen that setting the front guide vane 4 and the rear guide vane 5 on the rectangular cavity structure windshield 1 can significantly reduce eddies, make the airflow smooth, and significantly improve the wind speed inside the air duct 2.

[0161] To ensure more even wind distribution through the hollow wind energy collection column 3, multiple guide plates 6 are installed on its outer wall. These guide plates 6 are positioned along the height of the column 3 and are perpendicular to that direction. This straightens the wind as it passes through the guide plates 6, resulting in a more uniform distribution. Furthermore, the guide plates 6 act as reinforcing ribs, structurally strengthening the hollow wind energy collection column 3 and improving its rigidity.

[0162] pass Figures 17-20 It can be seen that setting the front guide vane 4 and the rear guide vane 5 on the rectangular cavity structure wind seat 1 can significantly reduce eddies, making the airflow smooth and significantly increasing the wind speed inside the air duct 2.

[0163] pass Figures 21-24 It can be seen that setting the front guide vane 4 and the rear guide vane 5 on the wind-catching seat 1 with the arc-shaped cavity structure and the outward convex arc on the windward side can also significantly reduce vortices, making the airflow smooth and the wind speed significantly increased in the air guide duct 2.

[0164] pass Figures 25-28 It can be seen that setting the front guide vane 4 and the rear guide vane 5 on the wind-catching seat 1 with the arc-shaped cavity structure and the concave arc-shaped windward side can also significantly reduce eddies, make the airflow smooth, and significantly increase the wind speed inside the air guide duct 2.

[0165] During wind speed simulation tests on the hollow wind energy collection column 3, it was found that when the angle between the airflow direction at the highest point of the hollow wind energy collection column 3 and the vertical direction is greater than 30°, the wind energy collection efficiency decreases. Therefore, the following principles should be followed when determining the height of the hollow wind energy collection column 3:

[0166] The angle between the airflow direction at the highest point of the hollow wind energy collection column 3 and the vertical direction is no greater than 30°.

[0167] In use, the side opening of the wind vane 1 and the windward side of the hollow wind energy collection column 3 are adjusted according to the wind vane. At this time, the wind blows from the hollow wind energy collection column 3, forming a negative pressure zone at its leeward side. The wind gathered into the wind vane 1 is drawn into the air duct 2 due to the existence of the negative pressure zone and is accelerated to 1.4-2 times its original speed. Finally, it flows out from the hollow wind energy collection column 3. During the wind flow, the turbine blades are driven to rotate, which in turn drives the generator to rotate and complete the power generation.

[0168] Example 6:

[0169] Reference Figure 29 The wind power generation device with embedded turbine blades in this embodiment includes a wind-catching unit, N turbine blade units and M generators, where N≥2 and 1≤M≤N.

[0170] Each turbine blade unit includes a hollow wind energy collection column 3 and turbine blades. The wind-collecting unit is still used to provide airflow to the turbine blades. The hollow wind energy collection column 3 has a curved windward surface, which is a concave arc plate or folded plate. N hollow wind energy collection columns 3 are installed on the top or bottom of the wind-collecting unit and are spaced apart. The hollow wind energy collection columns 3 are connected to the wind-collecting unit. N turbine blades are rotatably installed in the wind-collecting unit. The generator is connected to the turbine blades. The N turbine blades are used to drive M generators to rotate.

[0171] The difference from Embodiment 5 is that the duct unit includes a mounting frame 7 and N air ducts 2. The mounting frame 7 includes a top plate and multiple support columns set at the bottom of the top plate. Its structure is simpler than that of the duct seat 1, and the processing and maintenance costs are lower.

[0172] The air duct 2 can be a right-angle, obtuse-angle, or acute-angle bend structure. One end of the N air ducts 2 is installed at the bottom of the top plate of the mounting bracket 7, and the other end is flared. Since there is no wind-collecting seat 1 to gather the air, one end of the air duct 2 is set as a flared shape to increase the air intake area and play a certain role in gathering the air. In order to achieve the best wind gathering efficiency, in this embodiment, the air duct 2 adopts a right-angle bend structure.

[0173] Each turbine blade unit still includes a hollow wind energy collection column 3 and turbine blades. The hollow wind energy collection column 3 has a curved windward surface, which is a concave arc-shaped plate or a folded plate. Its structure is the same as that of the hollow wind energy collection column 3 in Embodiment 5, and will not be described again here. Multiple guide plates 6 can also be set on the hollow wind energy collection column 3 to rectify the wind and reinforce the structure of the hollow wind energy collection column 3. In this embodiment, N hollow wind energy collection columns 3 are installed vertically on the outer top surface of the top plate of the mounting frame 7 and are spaced apart. The ratio of the distance between the outer edges of adjacent hollow wind energy collection columns 3 to the width of the hollow wind energy collection column 3 is 30%-60%. The lower ends of the N hollow wind energy collection columns 3 are connected to one end of the corresponding N air guide pipes 2. Both the hollow wind energy collection column 3 and the air guide pipe 2 are connected to the top plate of the mounting frame 7 through bearings, and a wind vane is installed on the hollow wind energy collection column 3 or the mounting frame 7. In this way, the hollow wind energy collection column 3 can adjust the orientation of the windward side according to the wind direction to ensure the efficiency of wind power generation.

[0174] The turbine blades are rotatably installed inside the air duct 2. N turbine blades drive M generators. The structure of the turbine blades is the same as in Embodiment 5, and will not be repeated here. The generators can be coaxially connected to the turbine blades inside the air duct 2, coaxially connected to the turbine blades outside the air duct 2, or driven by transmission outside the air duct 2. This can be determined according to the actual situation. The generators can be coaxially connected to the turbine blades inside the air duct 2, which is suitable when there is enough space inside the air duct 2. If there is not enough space, a coaxial connection outside the air duct 2 can also be used. Alternatively, a drive shaft can be used to transmit the rotation of the turbine blades to the outside of the air duct 2, so that the generators are driven by transmission outside the air duct 2. In this case, multiple turbine blades can drive one generator, resulting in higher power output and better cost performance.

[0175] The windward side of the top plate can also be tilted downward to form a front wind vane 4, and the leeward side of the top plate can also be tilted downward to form a rear wind vane 5. The tilt angles of the front wind vane 4 and the rear wind vane 5 in this embodiment are the same as those in embodiment five, and their functions are also the same.

[0176] Example 7:

[0177] like Figure 30 As shown, this embodiment includes a wind-collecting unit, N turbine blade units, and M generators, where N ≥ 2 and 1 ≤ M ≤ N. Each turbine blade unit includes a hollow wind energy collection column 3 and turbine blades. The N hollow wind energy collection columns 3 are installed at the top or bottom of the wind-collecting unit and spaced apart.

[0178] The wind-collecting unit still provides airflow to the turbine blades, but in this embodiment, the wind-collecting unit includes a wind-collecting seat 1 and at least one wind-collecting column 9. The structure of the hollow wind energy collection column 3 is the same as in embodiment five, and will not be described again here. Multiple guide plates 6 can also be set on the hollow wind energy collection column 3 to rectify the wind and reinforce the structure of the hollow wind energy collection column 3.

[0179] Unlike the wind-collecting seat 1 in Embodiment 5, the wind-collecting seat 1 in this embodiment is a hollow structure without side openings. The wind-collecting column 9 and N hollow wind energy collection columns 3 are installed at intervals along the vertical direction on the top or bottom surface of the wind-collecting seat 1. The wind-collecting column 9 and N hollow wind energy collection columns 3 are respectively connected to the wind-collecting seat 1. In this embodiment, the wind-collecting column 9 and N hollow wind energy collection columns 3 are located on the top surface of the wind-collecting seat 1.

[0180] The wind-catching column 9 has the same structure as the hollow wind energy collection column 3, but the windward side faces the opposite direction. The air guide pipe 2 in embodiment 5 is replaced with the wind-catching column 9. In this way, it can be batch processed together with the hollow wind energy collection column 3 during processing, reducing costs.

[0181] The turbine blades are rotatably installed inside the wind-collecting column 9. The generator and the turbine blades are coaxially connected inside the wind-collecting column 9, coaxially connected outside the wind-collecting column 9, or connected by transmission outside the wind-collecting column 9. The above three installation methods can be flexibly selected according to the actual situation. The structure of the turbine blades is the same as that in Embodiment 5, and will not be described again here.

[0182] A front guide vane 4 can also be provided at the upper edge of the windward side of the wind-facing side of the wind-supporting base 1. The front guide vane 4 is inclined downward with an angle of 0-30°. The front guide vane 4 improves the airflow at the windward side of the lower end of the hollow wind energy collection column 3. A rear guide vane 5 is provided at the upper edge of the leeward side of the wind-supporting base 1. It is inclined downward with an angle of 0-40°. The rear guide vane 5 is used to improve the airflow at the leeward side of the lower end of the hollow wind energy collection column 3.
