Abstract

The present invention provides a vertical axial wind power generator, which is applied to a small and medium-sized wind power generator. The small and medium-sized wind power generator is provided with a plurality of blades rotated in a horizontal direction. Each horizontal blade has inner and outer wind collection vanes, so that the blades can be operated without being limited by space and environment and can be rotated vertically by tiny wind. When wind power is less than magnetic forces of magnets on the blades and fixing disks, the blades enter an open status to increase windward area. When the wind power is greater than the magnetic forces of the magnets on the blades and the fixing disks, a centrifugal force can force the blades to close to form a spherical shape. The blades expanded into the spherical shape have a torsion strengthening effect. At this time, the windward area of the outer wind collection vanes is minimized, so the rotation speed of the wind power generator can be reduced naturally. When the wind speed weakens, the blades return to the open state, so that each blade is curvedly swingable in an angle-limiting groove between a first fixing disk and a second fixing disk. By adjusting the blades to receive wind to reach the set rotation speed range, the purpose of protecting the wind power generator mechanism and extending the service life of the wind power generator can be achieved.

Description

Vertical axis wind turbine

The present invention provides a vertical axis wind power generator, especially a medium and small wind power generator. The wind power generator is provided with multiple blades that rotate in the horizontal direction. The horizontal blades are less affected by space and environment during operation. The limitation of the wind turbine can be rotated by only a small amount of wind.

According to the fact that industrial technology has made great progress, a large part of it is attributed to the invention of electricity. Since electricity can be used by ordinary households and industries, with the rise of various manufacturing industries and the pursuit of smart home appliances, global electricity consumption is almost It is growing year by year, and this has also caused a huge power gap. The main sources of traditional electricity in various countries are thermal power and nuclear power generation. Thermal power generation must consume a lot of fuel, which will inevitably lead to the exhaustion of fuel resources and at the same time cause great Nuclear power generation is the most efficient energy source for power generation. However, with the irregular nuclear energy disasters around the world, people’s fear of nuclear power has increased, and the anti-nuclear noise has also risen, causing countries to try to find alternative energy sources to replace the aforementioned Two main energy sources.

Alternative energy, also known as green energy, is the use of various forces in the natural environment to drive generators or store electricity. Green energy is mainly solar, wind, water, and ocean waves. Among them, wind power drives the fan blades to rotate and rotate. The mechanical energy generated by the generator is actuated to convert into electrical energy. Generally, the structure of a large horizontal axis wind turbine is a towering A vertical cross-shaped fan blade is installed at the upper end of the support column, and the fan blades can be driven to rotate by strong wind. This large-scale wind turbine is large in size, high in cost and limited in installation location (mostly Seaside or strong wind areas), so it cannot be promoted. Furthermore, the fan blades of this kind of large-scale wind turbine are fixed and cannot be adjusted with the wind direction. When the wind is too strong, the wind turbine cannot be operated. It is not a problem of wind turbines, but fear of wind. Too strong will cause the speed of rotation to be too fast. If the rated speed of the generator is exceeded, the generator will burn out. Therefore, when the wind is too strong, the large-scale wind generator will not be able to operate. Therefore, when the wind conditions cannot be matched, it will cause The inoperability of large-scale wind turbines directly affects the power generation efficiency. Seasonal and climate changes have always been the biggest variables in green energy. It is the efforts of those engaged in this industry to produce wind turbines that can minimize the impact of adverse factors in the external environment. The goal.

The conventional vertical axis wind turbine as shown in Figure 1 is the overall structure of the conventional wind turbine, which mainly includes an airfoil blade 1, a rotating shaft 11, a supporting beam 12, a generator set 13 and a vertical tower架14. The wind turbine is a wind turbine 13 combined with the upper end of a vertical tower 14. It is mainly a rotating shaft 11 with a plurality of airfoil blades 1 radially arranged on the periphery, and the airfoil blades 1 are curved arc wings When the airfoil blade 1 is blown by the wind, the rotating shaft 11 can be rotated to drive the generator set 13 to operate. However, the wind direction of the monsoon varies with the change of seasons. When the wind direction changes and the airfoil blade 1 cannot be adjusted and changed to correspond, the airfoil blade 1 is often forced to operate under the thrust of the slanted wind direction. Fatigue, aging and other problems caused by abnormal stress and damage. On the other hand, the size and design shape of the general airfoil blade 1 are fixed. When the wind speed is low, the area of the airfoil blade 1 is not large enough, and the wind resistance is not good, so that the generator set 13 cannot fully function; Power generation The mechanical energy of the unit 13 increases with the increase of wind speed. When encountering high winds (>14m/s), in order to avoid damaging the generator unit 13 and the charging system, it is necessary to stop the rotation or adjust the wind angle of the blades. The rated wind speed of many wind turbines is set at about 12m/s, and the wind speed for stopping power generation is set at about 15m/s. There is not much difference between the two. It is rare that there is a strong wind speed and the expected speed is full load power generation, but often encountered The shortcomings of braking due to over-speed operation must be prevented, which affects power generation efficiency and total power generation. Therefore, in order to improve the above-mentioned shortcomings such as the strength of the current airfoil blade 1 and the stability of the generator set 13, the inventor of the present case has actively conducted research, creation and design, and manufactured a light-weight, high-strength and time-saving processing. The structure of the airfoil blade 1 intercepts wind energy. The way to achieve good mechanical energy when the wind speed is low, and the wind resistance of the airfoil blade 1 can also be adjusted as the wind speed increases. Therefore, the matching of the wind turbine and the generator set 13 can be changed from breeze to strong wind. It can be adjusted within the safe matching range to cater to the wind and automatically reach the set speed range, for the purpose of protecting the wind turbine and extending the life and efficiency of the wind turbine. After many tests, it is finally innovative and available for industrial use. This is the subject to be solved by the present invention.

Therefore, in view of the above-mentioned problems and deficiencies, the inventor collected relevant information, and through multiple evaluations and considerations, he designed the invention of this type of wind turbine.

The main purpose of the present invention is to provide a vertical axis wind power generator, in which the wind power generator is equipped with multiple blades that rotate in the horizontal direction. The horizontal blades are less restricted by space and environment during operation, and only need a small amount of wind. When rotating, a first fixed disk is further provided under the first opening of the blades, and the first fixed disk is connected to each blade through a rotating pillar; a second fixed disk is provided above the second opening, and the second fixed disk is connected to the Each blade is connected by a rotating pillar, and each blade can be arced between the first fixed disk and the second fixed disk The main body is supported by three screw cylinders, square tube triangle plate and circular ring. The function of the circular ring is to hold the three screw cylinders at the same time to stabilize the main body and solve the shaking caused by uneven torsion. By adjusting the blades to cater to the wind, to protect the wind turbine mechanism and extend the life of the wind turbine.

The secondary purpose of the present invention is to provide an internal wind collecting blade on the inside of the blades to increase the wind-receiving area when the blades are opened. The blade structure intercepts wind energy to increase the starting torque to achieve a higher wind speed. It can produce good mechanical energy when it is low, so as to achieve the effect of rapid operation with breeze.

Another object of the present invention is to provide an external wind collecting blade on the outside of the blades to maintain the wind energy and constant speed operation time when the blades are closed, so as to protect the wind turbine mechanism and extend the wind power. The purpose of generator life and efficiency.

Another object of the present invention is to embed a magnet on the top of the rotating column, and embed the magnet in the first and second fixed disks. In the angle limiting grooves of the first and second fixed disks, the holes near the outer circle will be embedded The first magnet repels the magnet of the rotating column on the blade, and the hole near the center of the circle will enter the second magnet, so that the magnet in the inner hole and the magnet of the rotating column on the blade are attracted to each other. The magnets generate repulsion and attraction forces to assist the blades to rotate and prevent the blades from over-rotating, so that the plurality of blades can be closed or opened automatically at the same time.

Another object of the present invention is to embed a third magnet group of the same polarity in the blades, and the outer ring structure of the wind turbine is provided with a plurality of polarities (that is, the N-pole and S-pole magnets are alternately arranged). The four-magnet group, so that the third and fourth magnet groups generate magnetic field force that attracts and repels each other, which is similar to the operating principle of a motor (motor) to assist these The blades generate a breeze and start to rotate and prevent the blades from rotating at a high speed due to strong wind.

Another purpose of the present invention is that when the wind force is less than the magnetic force of the magnets on the blades, it will be open to increase the wind-receiving area; but when the wind force is greater than the magnetic force, the blades will be closed into a spherical shape; the blades are spherical It has the effect of strengthening torsion. At this time, the wind-receiving area is minimized, which naturally reduces the speed of the wind turbine. When the wind speed stabilizes, the blades return to the open state, and the left and right sides of the blade structure itself are not equal to the weight Due to the difference, depending on the rotation speed of the wind turbine, the plural blades can be automatically opened or closed at the same time. The wind force is used to make the left and right sides of the blade structure not equal to the weight difference, the internal and external airflow pressure difference of the blade structure, the centrifugal force, and the attraction of the magnet. Physical phenomena such as repulsive force and so on. When the wind turbine rotates, the multiple blades can realize and maintain the long-term stable automatic opening and closing function at the same time, so that the blades lose part of the wind-shielding function and reduce the help of the spindle. The thrust force can be used safely when the wind is too strong.

The function of the ring 5 is to simultaneously enclose the three screw cylinders 77 to stabilize The main body of the power generator solves the shaking caused by uneven torsion, and at the same time, the adjustment of the blades 2 caters to the wind, so as to protect the wind power generator and extend the life of the wind power generator.

Please refer to Figures 3-7, the blades 2 are assembled with two types of cylinders, one is a rotating column 23, and the other is a rotating column 24. The two ends of the rotating column 23 are equipped with ball bearings (35, 45 ), so that the rotating pillar 23 can smoothly and effectively make a circular rotation, and the rotating column 24 can make an arc swing at the angle limit grooves (31, 41) of the first and second fixed disks (3, 4). A magnet is embedded above the rotating column 24, and the magnet is embedded in the first and second fixed disks (3, 4). The first and second fixed disks (3, 4) are in the angular limit groove 31, which is close to the outer circle.

In this case, the permanent magnets or electromagnets on the outside of the blades 2 and the permanent magnets or electromagnets installed on the disk 5 are at the same level. Moreover, the size, magnetic force and quantity of the permanent magnets or electromagnets of the blades 2 and the disk 5 depend on the size of the actual wind turbine.

Please refer to Figures 2 to 11. Figure 11 is an exploded view of the wind generator of the present invention. The longitudinal center of the blade 2 is the fulcrum and is in the direction of rotation of the blade 2 When the side (the left side of the blade) is heavier than the right side of the blade 2, the plural blades 2 are in a spherical shape and can be rotated in a single direction. Therefore, when the environment is in a windless state (when the wind turbine is not rotating) and breeze According to the difference in weight between the left and right sides of all the blades 2, the left side of the blades 2 will be inclined toward the center point, which is beneficial for the blades 2 to capture the wind force, and form an internal and external resistance-lifting spherical shape that is easy to rotate. Correspondingly, the blades 2 will generate a large centrifugal force when rotating at a high speed. According to this centrifugal force, the left side of the rotating forward direction of the blades 2 (the left side of the blade 2) will slowly move away from the center point of the blades 2, and finally the blades 2 will be in a spherical closed state, and the blades 2 will no longer It is only the shape of the resistance-lift type that receives the wind, and the shape of the half-resistance and half-lift type that receives the wind. When the wind weakens, the centrifugal force of rotation becomes smaller, and the left side of the rotating direction of the blades 2 (the left side of the blade 2) will slowly approach the center point of the blades 2. At this time, the blades 2 show resistance again. The ascending shape is rotated by the wind. According to this structure, all the blades 2 can be automatically opened or closed at the same time and stable for a long time. Because it will not be affected by the balance of strength, performance, life and weight of springs, oil pressure, pneumatic telescopic connecting rods, etc., the stability of the rotation of the blade 2 can be improved, and the simplification of the structure can make the wind turbine The overall weight is lightweight, and the high-speed rotation of the wind turbine can be realized, and the maintenance or repair of the wind turbine is simpler and more efficient.

Each of the present invention is composed of six blades 2. These blades 2 exist independently. In terms of maintenance, one blade 2 can be replaced separately at a time, and there is no need for the large cross-shaped blades like the conventional offshore shape. The wind turbine will be replaced as a whole. The shape of the blade 2 is an arc-shaped piece that protrudes outward. In addition, an outer wind collecting blade 21 is installed on the outer side of the foremost front end of the blade 2 in the rotating forward direction (left side), and an inner wind collecting blade 22 is installed on the inner side. The shape of the left part of the blade 2 in the forward direction of rotation is heavier than the weight of the right side of the blade 2, and the left part of the blade 2 The shape and weight of the side part are larger than the right side to form a unidirectional rotation. Since the weight ratio of the left and right sides of the blades 2 is different, the heavier left side will definitely be inclined to the center point of the blades 2 to form a spherical state where the blades 2 can receive wind and easily rotate. In addition, the left part of the blade 2 has a streamlined shape, and the groove on the inner side of the blade 2 presents a high wind resistance shape, which can easily receive wind and generate rotation. The streamline in the direction of rotation of the blade 2 (left side of the blade), and the small blades of the outer wind collecting blade 21 and the inner wind collecting blade 22 on the inside and outside of the blade 2 are set at a wind catching angle relative to the streamlined shape from the left to the right of the blade 2 Bottom, the basic angle of outward expansion and the basic angle of outward expansion, the basic angles of the inner wind collecting blade 22 on the left side of the blade 2 and the outer wind collecting blade 21 on the outer side of the blade 2 are respectively set in the range of 10 to 60 degrees. When rotating, it can use the two forces of resistive lift and lift to realize the wind turbine from low speed to high speed and finally maintain stable speed rotation. And the top and bottom of the blade 2 are provided with a rotating pillar 23 to support and the direction of rotation is provided with a rotating column 24 to rotate, and each blade 2 is equipped with two ball bearings (35, 45) to make the blade 2 easy Rotate. The bearing components at the top and bottom of the blade 2 are mounted on the first and second fixed disks (3, 4), and these fixed disks (3, 4) rotate together with the central shaft 61 of the generator 6. The fixed disks (3, 4) have grooved rotation pillar holes (32, 42) for mounting bearing components in the center portion of the blade 2 at the top and bottom of the blade 2, and a bearing component that rotates the forward direction side Installed in the arc-shaped angle limit slot (31, 41). In addition, the rotation pillar holes (32, 42) and the angle limiting grooves (31, 41) on the fixed disks (3, 4) are shaped like a groove. The rotation pillar holes (32, 42) allow the blade 2 to rotate easily. The angle limit slot (31, 41) can set the movable range of the blade 2 (opening and closing angle), and at the same time, all the blades 2 can be opened and closed uniformly. The left side of the blade 2 is close to the angle limit slot. At the position of the center point of the blade 2, the opening angle of the blade 2 is the largest at this time, and the inner side of the blade 2 is most vulnerable to wind. Where the bearing of the blade 2 rotates the pillar 23, the left side of the blade 2 is at the position where the angle limit grooves (31, 41) are farthest from the center point of the blades 2. At this time, the blade 2 is closed and its interior is not under the wind shape. The length and width radian of the angle limiting groove (31, 41) and the diameter of the rotation pillar hole (32, 42) will be changed according to various bearing sizes. The length and width radian of the angle limiting slot (31, 41) is the moving range of the blade 2, and the moving range is expanded by 5 degrees to 50 degrees based on the center of the rotating pillar hole (32, 42). The feature of the present invention is that it can realize that the plurality of blades 2 can be automatically opened and closed without other mechanical switches at a rotation speed. The centrifugal force generated under the high-speed rotation of the blades 2 can make the blades 2 become spheres, so that they can no longer bear the safe state of excessive wind. However, suppose that the entire blades 2 become closed spheres due to centrifugal force before the predetermined rotation speed is reached. In this state, the number of rotations of the blades 2 that have become spheres cannot be increased, and may not be reached The predetermined amount of power generation, in order to prevent the spherical blades 2 from becoming closed before reaching the predetermined rotation speed, and to keep the blades 2 in the wind-receiving shape, the first and second fixed disks (3, 4) The angle limit slot (31, 41) is close to the center axis of the wind turbine, and the magnet (34, 44) is embedded, and its function is to absorb the two ends of the rotating column (24) running through the blade 2. The embedded magnets (34, 44) use the attractive force of the magnets (34, 44) to resist the centrifugal force during rotation. When the rotating speed of the wind turbine slows down and the centrifugal force is less than the magnetic force, the blades 2 will once again become an open state rotated by the wind, using the magnetic force of the fixed disks (3, 4) and the magnets (34, 44) on the blades 2 The attracting and repulsive forces of, enable the blade 2 to be continuously maintained in the open state at the low speed of the wind turbine. At this time, when the wind turbine continues to rotate and the speed is steadily rising slowly or not rising, it will generate The phenomenon of power reduction. When the speed of the wind generator has not reached the predetermined speed, the blade 2 must be kept in the wind-bearing shape at any time. The angle limit grooves (31, 41) of the fixed disks (3, 4) near the center of the blades 2 and away from the center of the blades 2 and the rotating column 24 in the direction of rotation of the blades 2 can be installed. Magnet 25 is installed where there is a bearing. The angular limit grooves (31, 41) of the fixed disks (3, 4) and the magnets (33, 43) arranged on the outside are connected with the rotating column 24 of the blade 2 in the forward direction of rotation. The magnets (34, 44) are equipped with bearings. ), to install magnets of the same polarity for repulsion. The angle limiting grooves (31, 41) of the fixed disks (3, 4) are installed near the central shaft 61 of the generator 6 to attract magnets of different polarity. The magnets can be arranged up and down or side by side. Under the action of the attraction and repulsion of the magnet, the attraction and repulsion of the magnet are used to make the blade 2 under the wind state before the predetermined speed arrives. In addition, drainage holes can be added in the angle limiting grooves (31, 41) on the first and second fixed disks (3, 4) on the top of the blade 2 to facilitate drainage.

The distance from the first opening to the second opening is a fixed value of the opening spacing 85. The widest part of the ellipsoid formed by the blades 2 in the horizontal direction is a width 86. The algebra of the hollow opening diameter 84 is D and The algebra of banner 86 is L, and a predetermined ratio R=D can be calculated by using the aforementioned two algebras /L, if the predetermined ratio R data is greater than 1, it means that the impeller is close to the concave hourglass shape, which is easy to cause the back pressure of the inflow airflow to affect the operation of the wind turbine; if the predetermined ratio R data is less than 1, it means the impeller is close to The convex ellipsoid allows the inflow air to flow to the diameter of the hollow openings at the first opening (below) and the second opening (above), without back pressure affecting the operation of the wind turbine. The predetermined ratio R ranges from 1:1 to 1:3. If the predetermined ratio R data approaches 1:1, it means that the ellipsoid is close to a cylinder; if the predetermined ratio R data approaches 1:1.5, it means The ellipsoid is close to a sphere; relatively, if the predetermined ratio R data approaches 1:3, it means that the ellipsoid is close to an oblate ellipsoid.

Please refer to Figure 13, which is a structural diagram of the wind turbine drive shaft of the present invention with multiple sets of windmill units connected in series, wherein the drive shaft 62 of the generator 6 is further connected with multiple sets of windmill units 9 in series.

Plural blades, horizontal blades in operation Less restricted by space and environment, it can be rotated by only a small amount of wind. When the wind is less than the magnet's attraction, these blades will be open to increase the wind area; but when the wind is stronger than the magnetic force, it will cause multiple blades Closed and presents a sphere. The blades are spherical and have the effect of strengthening the torsion. At this time, the area receiving the wind is minimized, which naturally reduces the speed of the wind turbine. When the wind speed stabilizes, the blades return to the open state. The blades are adjusted to cater to the wind to protect the wind turbine mechanism and extend the life of the wind turbine. At the same time, the blades are embedded with magnet groups of the same polarity, and a plurality of numbers are arranged on the outer ring of the wind turbine.
