Description

Technical Field

[0001] This utility model relates to wind power generation devices, specifically to environmentally friendly wind power generation systems and wind-solar power generation systems. 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

[0069] Compared with the prior art, the beneficial effects of this utility model are:

[0070] (1) The environmentally friendly wind power generation system provided by this utility model, when the wind passes through the hollow wind energy collection column, according to Bernoulli's principle and Venturi effect, will form a negative pressure zone at the leeward side. The wind entering from the side opening of the wind-collecting seat will be drawn into the air duct and accelerated due to the existence of the negative pressure zone. At this time, it will drive the turbine blades set in the air duct to rotate, thereby driving 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, compact overall structure, and small footprint. By combining the hollow wind energy collection column and the air duct, the airflow is optimized, the starting wind speed of the generator is reduced, and the low-speed wind resources in the city can be effectively utilized. Moreover, the two wind-collecting seats share the hollow wind energy collection column, saving material costs.

[0071] (2) The wind-collecting unit in the environmentally friendly wind power generation system provided by this utility model can use a wind-collecting seat with a cavity structure with a side opening to gather the wind. Alternatively, the air guide pipe can be set as a right-angle, obtuse-angle or acute-angle curved pipe structure with one end set as a flared mouth to increase the air intake area and play a certain gathering role on the wind. The wind-collecting efficiency of the wind-collecting seat is higher, while the support seat plus the air guide pipe structure with one end in a flared mouth is simpler and has lower processing and maintenance costs.

[0072] (3) The environmentally friendly wind power generation system provided by this utility model is equipped with a front wind vane and a rear wind vane, which improves the airflow at the windward and leeward sides of the hollow wind energy collection column, which is conducive to the formation of a negative pressure zone and accelerates the airflow speed in the wind duct.

[0073] (4) The environmentally friendly wind power generation system 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] (2) The environmentally friendly wind and solar power generation system provided by this utility model combines wind power generation and solar power generation. Wind power generation is achieved by combining the wind-collecting module with the hollow wind energy collection column, and solar power generation is achieved by the solar energy collection unit composed of multiple solar photovoltaic panels. The combination of the two makes full use of natural clean resources for power generation. Attached Figure Description

[0092] The present invention will be further described below with reference to the accompanying drawings and exemplary embodiments.

[0093] Example 1 of an environmentally friendly wind power generation system:

[0094] Reference Figures 1-6The environmentally friendly wind power generation system of this utility model includes two wind-collecting modules and N hollow wind energy collection columns 3. Each wind-collecting module includes a wind-collecting unit, N sets of turbine blades and M generators, where N≥1 and 1≤M≤N.

[0095] The wind-collecting unit is used to provide airflow to the turbine blades. In this embodiment, the wind-collecting unit includes a wind-collecting seat 1 and N air guide pipes 2 disposed within the wind-collecting seat 1. The wind-collecting seat 1 is a cavity structure with side openings. Two wind-collecting seats 1 are arranged opposite each other with the side openings facing the same direction. The wind-collecting seat 1 is a polygonal cavity structure or an arc-shaped cavity structure, and the side openings all face the windward side. For ease of manufacturing, in this embodiment, the wind-collecting seat 1 adopts a rectangular cavity structure within the polygonal cavity structure. To ensure the wind-gathering efficiency of the wind-collecting seat 1, a base is provided below the wind-collecting seat 1. The bottoms of the two wind-collecting seats 1 are connected to the base through the same bearing, so that the entire device can rotate, allowing the side openings of the wind-collecting seat 1 to face the wind direction. To detect the wind direction, a wind vane is provided on the wind-collecting seat 1 or the hollow wind energy collection column 3.

[0096] N hollow wind energy collection columns 3 are located between two wind-collecting bases 1 and are spaced apart vertically. Each hollow wind energy collection column 3 has a curved windward surface, which is made of a concave arc-shaped plate or a folded plate, with its two ends mounted on the opposite sidewalls of the two wind-collecting bases 1. When the hollow wind energy collection column 3 is made of a concave arc-shaped 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. Due to the shape of the hollow wind energy collection column 3, when wind blows across it, a negative pressure zone is formed at its leeward side according to Bernoulli's principle and the Venturi effect.

[0097] The air duct 2 is a cylindrical structure. N air ducts 2 in each wind-collecting seat 1 correspond to N hollow wind energy collection columns 3. Each air duct 2 is installed on the inner side wall of the wind-collecting seat 1. The two ends of the hollow wind energy collection column 3 are respectively connected to the two corresponding air ducts 2.

[0098] Alternatively, the air duct 2 remains a cylindrical structure, but N air ducts 2 are set outside the wind-collecting base 1 and respectively inside the N hollow wind energy collection columns 3. Each air duct 2 is installed on the outer wall of the wind-collecting base 1, and the hollow wind energy collection columns 3 and the air duct 2 are all connected to the wind-collecting base 1.

[0099] The turbine blades are coaxially mounted inside the air duct 2, and the N sets of turbine blades in each air intake module drive M generators to rotate. The turbine blades adopt the NACA-4415 airfoil with a chord length c. i Distribution according to formula

[0100]

[0101] 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 cross-section of the turbine blade. i Let B be the axial induction factor for the i-th cross section, and B be the number of turbine blades.

[0102] Furthermore, the angle of attack of the turbine blades decreases from 8° at the root to 4° at the tip.

[0103] The correspondence between the turbine blades and the generator can be determined according to the actual situation. The generator and turbine blades can be coaxially connected inside the air duct 2, with one set of turbine blades corresponding to one generator – this is the simplest connection method. Alternatively, the generator and turbine blades can be coaxially connected outside the air duct 2. This is in the case where the space inside the air duct 2 is insufficient to install the generator, so the generator is placed outside the air duct 2 and then connected to the turbine blades. Another possibility is that the generator and turbine blades are connected via a transmission system outside the air duct 2. Figure 2 As shown, several sets of turbine blades are connected to a generator via a drive shaft, which increases the power generation capacity, provides a high cost-performance ratio, and is suitable for areas with frequent low-speed winds.

[0104] In order to facilitate the formation of a negative pressure zone, a front wind vane 4 is provided at the edge of the opening on the side of the wind-collecting column 3, which is used to improve the airflow at the windward side of the hollow wind-collecting column 3. The front wind vane 4 is tilted away from the hollow wind-collecting column 3, and the tilt angle is 0-30°.

[0105] The rear wind guide 5 is located on the leeward side of the wind-collecting column 3 near the edge of the hollow wind energy collection column 3. The rear wind guide 5 is used to improve the airflow at the leeward side of the hollow wind energy collection column 3. The rear wind guide 5 is tilted away from the hollow wind energy collection column 3, and the tilt angle is 0-40°.

[0106] To allow wind to pass more evenly through the hollow wind energy harvesting column 3, such as... Figure 13 As shown, multiple guide plates 7 are installed on the outer wall of the hollow wind energy collection column 3. These guide plates 7 are arranged along the length of the hollow wind energy collection column 3 and are perpendicular to its length. This ensures that the wind is rectified when passing through the guide plates 7, resulting in a more uniform distribution. Furthermore, the guide plates 7 act as reinforcing ribs, structurally strengthening the hollow wind energy collection column 3 and improving its rigidity.

[0107] according to Figures 3-6 As can be seen, the wind power generation system in this embodiment significantly reduces eddies, resulting in smooth airflow and a noticeable increase in wind speed within the air duct 2.

[0108] When in use, adjust the orientation of the side opening of the wind-collecting seat 1 according to the wind direction. Then, when the wind blows over the hollow wind energy collection column 3, a negative pressure zone is formed on its leeward side. Because of the existence of the negative pressure zone, the wind gathered by the wind-collecting seat 1 is drawn into the air duct 2 and accelerated, and finally flows out from the hollow wind energy collection column 3. In the whole process, the turbine blades will be driven to rotate, which in turn drives the generator to rotate and complete the power generation.

[0109] Example 2 of an environmentally friendly wind power generation system

[0110] The difference from Example 1 is that, as Figure 7 As shown, in this embodiment, the wind-collecting unit of the wind-collecting module includes a support base 6 and N air guide pipes 2 disposed within the support base 6. The support base 6 includes side walls and a support frame disposed on one side of the side plate. Two support bases 6 are arranged opposite each other, and N hollow wind energy collection columns 3 are located between the two support bases 6 and spaced apart in the vertical direction. The two ends of the hollow wind energy collection columns 3 are respectively connected to the opposite side walls of the side plates of the two support bases 6. The structure of the hollow wind energy collection columns 3 is the same as that in Embodiment 1, and will not be described again here. Moreover, the hollow wind energy collection columns 3 in this embodiment are the same as those in Embodiment 1, and multiple guide plates 7 can be disposed on their outer walls.

[0111] The air duct 2 is a right-angled, obtuse-angled, or acute-angled bend. In this embodiment, a right-angled bend is used for ease of manufacturing. Each support base 6 contains N air ducts 2 corresponding to N hollow wind energy collection columns 3. One end of the air duct 2 is installed on the inner wall of the side plate of the support base 6, and the other end is flared. The two ends of the hollow wind energy collection columns 3 are connected to the corresponding two air ducts 2. Because the support base 6 only serves a supporting function in this embodiment and cannot concentrate the wind, the flared shape increases the air intake area of ​​the air duct 2, thus concentrating the wind to a certain extent.

[0112] The turbine blades are rotatably installed inside the air duct 2. Each air intake module's N sets of turbine blades drive M generators. The correspondence between the turbine blades and generators can be determined based on actual conditions. The generators and turbine blades can be coaxially connected inside the air duct 2, with one set of turbine blades corresponding to one generator – this is the simplest connection method. Alternatively, the generators and turbine blades can be coaxially connected outside the air duct 2. This is in the case where there is insufficient space inside the air duct 2 to install the generators, so the generators are placed outside the air duct 2 and then connected to the turbine blades. Another option is a drive connection between the generators and turbine blades outside the air duct 2. Figure 2 As shown, several sets of turbine blades are connected to a generator via a drive shaft, which increases the power generation capacity, provides a high cost-performance ratio, and is suitable for areas with frequent low-speed winds.

[0113] Of course, the windward side of the side plate of the support base 6 can also be tilted away from the hollow wind energy collection column 3 to form a front wind guide 4. The tilt angle is the same as in the first embodiment, which is 15°±5°. The leeward side of the side plate can also be tilted away from the hollow wind energy collection column 3 to form a rear wind guide 5. The tilt angle is the same as in the first embodiment, which is 20°±10°.

[0114] A base is provided at the bottom of the two support seats 6. The bottom of the two support seats 6 is connected to the base through the same bearing. This allows the entire device to rotate so that the flared end of the air duct 2 and the windward side of the hollow wind energy collection column 3 can face the wind direction, thereby improving power generation efficiency.

[0115] Example 3 of an environmentally friendly wind power generation system:

[0116] Reference Figures 8-12 The most significant difference between the environmentally friendly wind power generation system of this utility model and Embodiment 1 is that one of the wind-catching units is replaced with a mounting base 8 to improve the overall support stability of the device.

[0117] In this embodiment, the structure of the wind-collecting module and the hollow wind energy collection column 3 is the same as that in Embodiment 1, and will not be described again here.

[0118] The duct 1 and the mounting base 8 are arranged opposite each other. N hollow wind energy collection columns 3 are located between the duct 1 and the mounting base 8 and are spaced apart in the vertical direction. N air guide pipes 2 are arranged inside the duct 1 and are respectively arranged for the N hollow wind energy collection columns 3. Each air guide pipe 2 is installed on the inner side wall of the duct 1. The two ends of the hollow wind energy collection column 3 are connected to the opposite side walls of the duct 1 and the mounting base 8, respectively. One end of the hollow wind energy collection column 3 is connected to the corresponding air guide pipe 2, while the end connected to the support base 6 can be sealed or opened. Because only one duct module is used, one end of the N hollow wind energy collection columns 3 will be suspended and the structure will be unstable. Therefore, the mounting base 8 supports one end of the hollow wind energy collection column 3 to ensure structural stability. In this embodiment, the hollow wind energy collection column 3 is the same as that in the first embodiment, and multiple guide plates 7 can be arranged on its outer wall.

[0119] Alternatively, the air duct 2 is still a cylindrical structure, but N air ducts 2 are set outside the wind-collecting seat 1 and respectively set inside the N hollow wind energy collection columns 3. Each air duct 2 is installed on the outer wall of the wind-collecting seat 1, and the hollow wind energy collection columns 3 and the air duct 2 are all connected to the wind-collecting seat 1.

[0120] To ensure the wind-gathering efficiency of the wind-collecting seat 1, a base is provided below the wind-collecting seat 1 and the support seat 6. The bottom of the wind-collecting seat 1 and the support seat are connected to the base through the same bearing, so that the entire device can rotate on the base, thereby adjusting the orientation of the side opening of the wind-collecting seat 1 and the orientation of the windward side of the hollow wind energy collection column 3 to ensure that both are aligned with the wind direction. In order to detect the wind direction, a wind vane is provided on the hollow wind energy collection column 3 or the wind-collecting seat 1.

[0121] In this embodiment, the turbine blades are coaxially mounted inside the air duct 2. The N sets of turbine blades of the wind-guiding module drive M generators to rotate. The correspondence between the turbine blades and the generators is determined according to the actual situation. The generators and turbine blades can be coaxially connected inside the air duct 2, which is the simplest connection method, with one set of turbine blades corresponding to one generator. Alternatively, the generators and turbine blades can be coaxially connected outside the air duct 2. In this case, the space inside the air duct 2 is insufficient to install the generators, so the generators are placed outside the air duct 2 and then connected to the turbine blades. Or, the generators and turbine blades can be driven to each other outside the air duct 2, and several sets of turbine blades can be driven to one generator through a drive shaft. This increases the power generation and is suitable for areas with more low-speed winds.

[0122] In order to facilitate the formation of a negative pressure zone, a front wind vane 4 is provided at the edge of the opening on the side of the wind-collecting column 3. This front wind vane 4 is used to improve the airflow at the windward side of the hollow wind-collecting column 3. The front wind vane 4 is tilted away from the hollow wind-collecting column 3, and the tilt angle is 15°±5°.

[0123] The rear wind guide 5 is located on the leeward side of the wind-collecting column 3 near the edge of the hollow wind energy collection column 3. The rear wind guide 5 is used to improve the airflow at the leeward side of the hollow wind energy collection column 3. The rear wind guide 5 is tilted away from the hollow wind energy collection column 3, and the tilt angle is 20°±10°.

[0124] To allow wind to pass more evenly through the hollow wind energy harvesting column 3, such as... Figure 13 As shown, multiple guide plates 7 are installed on the outer wall of the hollow wind energy collection column 3. These guide plates 7 are evenly distributed along the length of the hollow wind energy collection column 3, and all guide plates 7 are perpendicular to the length of the hollow wind energy collection column 3. This ensures that the wind is rectified when passing through the guide plates 7, resulting in a more uniform distribution. Furthermore, the guide plates 7 also act as reinforcing ribs, structurally strengthening the hollow wind energy collection column 3 and improving its rigidity.

[0125] according to Figures 9-12 As can be seen, the wind power generation device in this embodiment significantly reduces eddies, resulting in smooth airflow and a significant increase in wind speed within the air duct 2.

[0126] Example 4 of an environmentally friendly wind power generation system:

[0127] Reference Figure 14 The main difference between this embodiment and embodiment two is that one of the wind-collecting modules is replaced with the mounting base 8, while the structure of the remaining wind-collecting modules and the hollow wind energy collection column 3 is the same as that in embodiment two, and will not be described again here.

[0128] N hollow wind energy collection columns 3 are located between the support base 6 and the mounting base 8, and their two ends are respectively connected to the side plate of the support base 6 and the side wall of the mounting base 8.

[0129] To adapt to changes in wind direction, a base is provided at the bottom of the support 6 and the mounting base 8. The bottoms of both are connected to the base through the same bearing, so that the entire device can rotate so that the flared end of the air duct 2 and the windward side of the hollow wind energy collection column 3 can face the wind direction, thereby improving power generation efficiency. In addition, the hollow wind energy collection column 3 in this embodiment is the same as that in embodiment two, and multiple guide plates 7 can be provided on its outer wall.

[0130] In this embodiment, the turbine blades are coaxially mounted inside the air duct 2. The N sets of turbine blades in the air duct module drive M generators to rotate. The correspondence between the turbine blades and the generators is determined according to the actual situation. The generators and turbine blades can be coaxially connected inside the air duct 2, with one set of turbine blades corresponding to one generator, which is the simplest connection method. Alternatively, the generators and turbine blades can be coaxially connected outside the air duct 2. This is because there is not enough space inside the air duct 2 to install the generators, so the generators are placed outside the air duct 2 and then connected to the turbine blades. Or, the generators and turbine blades can be connected by a transmission mechanism outside the air duct 2. Figure 7 As shown, several sets of turbine blades are connected to a generator via a drive shaft, which increases the power generation capacity and is suitable for areas with more low-speed winds.

[0131] Examples of environmentally friendly wind and solar power generation systems:

[0132] like Figure 15 As shown, the environmentally friendly wind and solar power generation system in this embodiment includes at least one wind-catching module, N hollow wind energy collection columns 3 and multiple solar photovoltaic panels 9;

[0133] In this embodiment, the wind-catching module includes a wind-catching unit, N sets of turbine blades, and M generators, where N≥1, 1≤M≤N. The structure of the wind-catching module is the same as in the above-described environmentally friendly wind power generation system embodiments one to four. The wind-catching unit can be a wind-catching seat 1 or a support seat 6, which can be flexibly selected according to the situation.

[0134] The structure of the hollow wind energy collection column 3 and the turbine blades is the same as in the above embodiment, and will not be described in detail here. One end of the hollow wind energy collection column 3 is connected to the side wall of the wind-collecting unit and communicates with each other. N sets of turbine blades are set corresponding to N hollow wind energy collection columns 3 and are rotatably installed inside the wind-collecting unit. The turbine blades are connected to the generators, and the N sets of turbine blades are used to drive M generators to rotate.

[0135] The connection between the turbine blades and the generator is the same as in the above embodiments, and will not be repeated here.

[0136] Multiple solar photovoltaic panels are arranged in an array to form a solar energy collection unit. The solar energy collection unit is located below the hollow wind energy collection column 3 and is connected to the side wall of the wind-collecting unit on one side. This structure may be unstable during use. Therefore, a wind-collecting module or mounting base is set at the other end of the hollow wind energy collection column 3. In this way, both ends of the hollow wind energy collection column 3 and both sides of the solar energy collection unit are supported, making it more stable during use. Compared with wind power generation systems, wind and solar power generation systems make better use of clean energy. During the day when electricity consumption is high, the two work together to generate electricity, and at night when electricity consumption is low, wind power generation is used.

[0137] The embodiments described above are merely descriptions of specific implementations of this utility model and are not intended to limit the scope of this utility model. Various modifications and improvements made to the technical solutions of this utility model by those skilled in the art without departing from the spirit of this utility model should fall within the protection scope defined by the claims of this utility model.
