Description

The present invention is a kind of wind power generation device, and in particular, it can increase the output power and cost performance index (CPINDEX) of wind power generation.

The wind power generator is roughly divided into a vertical axis wind power generator 5 (FIG. 1) and a horizontal axis wind power generator 6 (FIG. 2) according to the direction of the rotation axis. The structure of a wind power generator is mainly composed of three parts: a tower, blades, and a generator. Among other things, the space and structure features of the tower are unfortunately used only to support one type of blade and generator, not for other purposes.

The inventor believes that the space, structure, and composition occupied by the tower has room for other functions sufficient to increase the output power of the power generation, which, through repeated research, can be achieved. It has been improved and led to the present invention.

In order to solve the above problems, the main object of the present invention is to change the structural design of the tower, the use of space, and its wind power function. The combination of blade and generator design, configuration, and system also improves the output and cost-performance efficiency of the wind turbine.

The main feature of the present invention is that a support shaft is installed in the tower of the wind power generator, and the support shaft installed in the tower is pivotally connected to the upper and lower vertical axis blades arranged vertically. Is Rukoto. The outer wall of the tower corresponds to two vertical axis blades above and below, and has a wind direction opening, and crosswinds can enter the tower through the wind direction opening and push and rotate the upper and lower vertical axis blades. Since the rotation directions of the upper and lower vertical axis blades are configured to rotate in opposite directions, the rotational torques of the upper and lower vertical axis blades are balanced with each other. In addition, the upper and lower vertical axis blades are connected to the generator unit to generate electricity with the output rotational force. This installation installs multiple blades and generators in addition to the one wind blade and generator originally supported by the tower described in the prior art, utilizing the aerodynamic design within the tower overall. It is possible to enhance the power generation effect.

With respect to the technical means and structures employed by the present invention to achieve the above objectives and effects, the following embodiments are provided with illustrations and description is as follows.

In the present invention, it is possible to install a plurality of blades and generators and utilize the aerodynamic design in the tower to enhance the overall power generation effect.

It is another structural drawing in embodiment of the induction stator magnetic field of this invention. It is a hollow tubular structure figure of the support shaft in embodiment of this invention.

Please refer to FIGS. 3 to 8 which are structural diagrams of the embodiment of the present invention applied to the vertical axis wind power generator 1. The vertical axis wind power generator 1 includes a hollow tower 2, a pair of upper and lower rotating blades 10a and 10b supported above the upper part of the tower 2. The rotary blades 10a and 10b can be driven to rotate by natural wind and are connected to a generator (not shown) to generate electricity.

The main improvements of the present invention are as follows.

The tower 2 is a hollow pillar having a hollow space 20 inside. The outer periphery of the tower 2 is surrounded by a plurality of columns 21, and the side wall of the columns 21 is connected to the outer peripheral wall 22 of the tower 2. In this way, the structural strength of the tower 2 is improved, thereby reducing the material requirements of the plate material constituting the outer peripheral wall 22 of the tower 2 and reducing the cost. The immovable support shaft 23 is installed inside the hollow space 20, and the upper end of the support shaft 23 extends from the upper opening of the tower 2 to pivotally connect the above-mentioned rotating blades 10a and 10b. The outer peripheral wall 22 located at the lower end of the tower 2 includes a plurality of down vents 220 that can be opened and closed to increase the aerodynamic energy in the tower 2. Further, since the outer peripheral wall 22 at the bottom of the tower 2 is light-transmitting, the air inside the tower 2 can be heated, and the hot air under the tower 2 rises upward according to the principle of the hot air rising from the down vent 220 to the tower 2. Upon entering, the hot air moves upward due to the chimney effect. Alternatively, the air in the tower 2 is driven downward by electric power and transmitted to another tower 2 for application through the down vent 220.

At least two vertically arranged upper vertical axis blades 24a and lower vertical axis blades 24b are pivotally connected on the support shaft 23 at the inner upper end of the tower 2 (FIGS. 3 and 4). Each of the upper and lower vertical axis blades 24a, 24b includes half-barrel-shaped auxiliary blades 25a, 25b connected to the corresponding vertical axis blades 24a, 24b. The half-barrel-shaped auxiliary blades 25a, 25b can absorb more lateral wind, help initiate rotation of the upper and lower vertical axis blades 24a, 24b, and guide the airflow. Since the rotation directions of the upper and lower vertical axis blades 24a and 24b are configured to rotate in opposite directions, the two rotational torques are balanced. Further, the rotational kinetic energy of the upper and lower vertical axis blades 24a and 24b is connected to the generator by a gear mechanism and can be individually generated. In order to increase the rotation speed of the upper and lower vertical axis blades 24a and 24b, the blade shapes of the upper and lower vertical axis blades 24a and 24b are changed.
It can be designed to be pushed and rotated by the wind moving upward from the tower 2 due to the chimney effect. The blade shapes of the upper and lower vertical axis blades 24a, 24b can also have the effect of being rotated by the wind from the tower 2 moving upward by the chimney effect, by design.

The outer peripheral wall 22 of the tower 2 is provided with a wind direction opening 26 at a position corresponding to the upper and lower vertical axis blades 24a and 24b (as shown in FIG. 7, has at least one wind direction opening, and this embodiment. In the form, there are multiple wind direction openings). The wind that naturally flows outside the tower 2 enters the tower 2 through the wind direction opening 26 and can be rotated by pushing the upper and lower vertical axis blades 24a and 24b and the two auxiliary blades 25a and 25b. As shown in FIG. 7, wind suction plates 221 inclined to the outside of the tower 2 are installed on both sides of the outer peripheral wall 22 corresponding to the wind direction opening 26 in order to increase the air volume.

A horizontally installed induction stator magnetic field 27 is fixed to the tower 2 between the upper and lower vertical axis blades 24a and 24b that are vertically adjacent to each other. The induction stator magnetic field 27 includes a grid hole-shaped metal plate 270 and an excitation coil 271 wound around the metal plate 270 (FIG. 4). The outer circle of the metal plate 270 is supported and positioned by the inner wall of the tower 2. The end faces of the upper and lower vertical axis blades 24a, 24b facing the induced stator magnetic field 27 include axial flow blades 28a, 28b that rotate with the upper and lower vertical axis blades 24a, 24b, respectively (ie, axial flow blades). When the 28a and 28b rotate, the direction of the wind flow in the hollow space 20 of the tower 2 can be driven in the axial direction). The two axial flow blades 28a, 28b rotate together with the attached vertical axis blades 24a, 24b. The rotation directions of the two axial flow blades 28a and 28b are opposite, but the angle of the blades is designed so that the direction in which the wind force is pushed is constant (for example, the wind direction is constant upward). The two axial flow blades 28a, 28b are magnetized to form the rotor magnetic fields 29a, 29b, and the inductive stator magnetic field 27 faces the two rotor magnetic fields 29a, 29b through the rotation of the rotor magnetic fields 29a, 29b. It induces each other with the induced stator magnetic field 27 and magnetically cuts to generate electricity. The power generation function increases the power generated by rotating the two rotor magnetic fields 29a and 29b in opposite directions. Further, an upper axial flow blade 28c that rotates together with the upper vertical axis blade 24a is provided at the upper end of the upper vertical axis blade 24a, and the lower end of the lower vertical axis blade 24b is coupled and interlocked with the lower vertical axis blade 24b. It is equipped with a lower axial flow blade 28d. The upper axial flow blade 28c and the lower axial flow blade 28d are installed so as to increase the pushing of the internal axial flow of the tower 2.

As shown in FIGS. 3 and 5, two auxiliary axial flow blades 28e and 28f located below the support shaft 12 of the hollow space 20 and installed separately from the upper part and the lower part are pivotally connected. The two auxiliary axial flow blades 28e and 28f are designed so that the blade angles of the two auxiliary axial flow blades 28e and 28f are reversed when receiving axial flow wind, like the two axial flow blades 28a and 28b described above. Therefore, the two rotational torques are balanced, the wind direction is the same, and the blades are magnetized to form the rotor magnetic fields 29c and 29d. The inductive stator magnetic field 27a is installed between the two auxiliary axial flow blades 28e and 28f, and the inductive stator magnetic field 27a is the same as the above-mentioned inductive stator magnetic field 27. It consists of a grid hole shaped metal plate 270a and an excitation coil 271a wound around the metal plate 270a. The rotation of the rotor magnetic fields 29c and 29d induces each other with the induction stator magnetic field 27a and magnetically cuts them to generate electricity. Further, the rotation directions of the rotor magnetic fields 29c and 29d are opposite, which can increase the power generated by mutual induction with the induced stator magnetic field 27a. Further, the rotation of the two auxiliary axial flow blades 28e, 28f can assist the flow velocity of the axial wind flowing from the down vent 220 into the tower 2, which seems to be a small tornado effect. The rotation of the two auxiliary axial flow blades 28e, 28f is the opposite of the above design, which increases the amount of mutual induction and magnetic cutting between the rotor magnetic fields 29c, 29d and the induced stator magnetic field 27a. Thereby, the power generation effect can be increased. Further, the two auxiliary axial flow blades 28e and 28f have opposite directions as described above, but the shape of the blades can be designed to achieve a certain wind direction function. Further, the pushing wind direction is limited to the same direction as the wind direction pushed by the axial flow blades 28a, 28b, so that the axial flow blades 28a, 28b and the two auxiliary axial flow blades 28e, 28f are in the tower 2. It has the effect of pushing the flow speed of the wind flowing in the axial direction inside with a relay. Next, the induced stator magnetic field 27a can be removed between the two auxiliary axial flow blades 28e and 28f, and the rotational kinetic energy of the two auxiliary axial flow blades 28e and 28f drives the generator by the gear mechanism. Can generate electricity, thereby increasing the power generation effect.

As shown in FIGS. 3 and 5, the above embodiment of the present invention is applied to the vertical axis wind power generator 1. The upper and lower rotary blades 10a and 10b exposed above the tower 2 are installed in the hollow space 20 of the tower 2 except that they are pushed by natural wind to rotate and the rotational power is connected to a generator to generate electricity. The vertical axis blades 24a and 24b can also generate electricity when connected to individual connected generators by rotational power. The two axial flow blades 28a and 28b are magnetized to form rotor magnetic fields 29a and 29b, and can generate mutual induction 27 and magnetic cutting with the induction stator magnetic field, and the two axial flow blades 28e and 28f. Is magnetized to form rotor magnetic fields 29c and 29d, and can also generate mutual induction 27 and magnetic cutting with the induction stator magnetic field.
Therefore, the present invention has the effect of increasing the amount of power generation. Further, the present invention is provided with a plurality of down vents 220 on the bottom outer peripheral wall 22 of the tower 2 so that hot air under the tower 2 can enter the tower 2 through the down vent 220. Based on the principle of the chimney effect, the axial wind in the tower 2 is from below via the auxiliary axial blades 28e, 28f, the lower axial blades 28d, the two axial blades 28a, 28b, and the upper axial blades 28c. It is relayed above, and the wind in the axial direction is very large like a small tornado effect, and the wind speed in the direction of the tower 2 can be increased to improve the power generation effect.

Next, refer to FIG. 9, which is a structural diagram of an embodiment of the present invention applied to the horizontal axis wind power generator 3. This is the same as that of FIGS. 3 and 5 in the structure of the tower 2 and the internal mechanical structure of the tower 2.

As shown in FIG. 10, the lower end between the vertical axis wind power generator 1 and the tower 2 of the horizontal axis wind power generator 3 is connected by a light transmissive connecting pipe 4 at a down vent 220. Further, the axial wind direction of the tower 2 can be designed, and the axial wind direction in the tower of the horizontal axis wind power generator 3 is downward (indicated by the arrow A), while the tower 2 of the vertical axis wind power generator 1 can be designed. The axial wind direction inside is upward. (Indicated by arrow B). The axial wind in the tower 2 of the horizontal axis wind power generator 3 is heated by the outside temperature of the light transmissive connecting pipe 4 and then flows into the tower of the vertical axis wind power generator 1 according to Bernoulli's Law. The air volume in the tower of the vertical axis wind power generator 1 can be increased. Then, the chimney effect increases the air volume and rotation speed of the vertical shaft blades 24a and 24b, the axial flow blades 28a and 28b, the auxiliary axial flow blades 28e and 28f of the tower 2, and enhances the power generation effect. Alternatively, as shown in FIG. 11, the down vent 220 between one horizontal axis wind power generator 3 and the plurality of vertical axis wind power generators 1 is connected by a connecting pipe 4, or a plurality of vertical axis wind power generators. The down vent 220 between 1 and the plurality of horizontal axis wind power generators is also connected by the connecting pipe 4. By setting the wind direction in the forward direction in this way, it is possible to introduce the winds in different towers 2 into the adjacent towers 2 and enhance the wind power generation effect.

Next, the structures of the two auxiliary axial flow blades 28e, 28f and the induced stator magnetic field 27a shown in FIG. 5 can be as shown in FIG. The two auxiliary axial flow blades 28e and 28f rotate in reverse and have an S pole and an N pole by being magnetized. As shown in FIG. 12, the structure of the induced stator magnetic field 27a is such that the ring of the permanent magnet 271c is attached to the inner wall of the tower 2 corresponding to the installation positions of the two auxiliary axial flow blades 28e and 28f. It has a set of horizontal excitation coils 271b extending horizontally between the two auxiliary axial flow blades 28e and 28f from the center of the permanent magnets 271c, and the horizontal excitation coils 271b are from the permanent magnets 271c above and below the horizontal excitation coils 271b. The vertical excitation coil 271b is extended and the two vertical excitation coils 271b are installed adjacent to the two auxiliary axial flow blades 28e and 28f, respectively. When the two magnetized auxiliary axial blades 28e and 28f rotate, they move with respect to the excitation coil 271b and generate electricity by cutting the magnetic field lines, and the two auxiliary axial blades 28e and 28f rotate in opposite directions. However, this can increase power generation.

Further, a filter material capable of absorbing carbon dioxide is installed inside the tower 2, and the filter material such as sodium bicarbonate or potassium carbonate can capture carbon from air or exhaust gas (carbon capture). ). When air or exhaust gas is drawn into the interior space of the tower 2, it is filtered and discharged by the above-mentioned filtering material, and the carbon dioxide content emitted by the atmosphere and human beings can be reduced. In addition, the electricity generated by the wind electrolyzes seawater to produce sodium hydroxide, hydrogen, and chlorine, the former reduces carbon, hydrogen can be used as a fuel cell, and chlorine is used as an industrial material. Use can be enhanced. As shown in FIG. 13, the support shaft 23 can be set to be tubular, and the tower 2 has inner and outer pipes (upper axial flow blade 28c, induced stator magnetic field 27, 27a, upper vertical shaft blade 24a, lower vertical). Components such as axial blades 24b are omitted and not shown). Further, the axial fan 5 is installed inside the upper part of the support shaft 23, the outer wall at the lower end is provided with some air outlets 50 communicating with the inside of the tower 2, and the axial fan 5 is the support shaft 23. The cold air above can be carried into the support shaft 23. Next, the cold air flows downward through the support shaft 23, then flows out from the air outlet 50 and gathers between the tower 2 and the support shaft 23, increasing the wind energy flowing upward from the lower end of the tower 2.
