Description

  The present invention relates to a wind power generator. Specifically, for example, it relates to a vertical wind power generator.

When fossil fuels such as oil and natural gas occupy a large amount of energy supply, there is a problem that the energy supply becomes unstable due to the influence of fluctuating market prices of fossil fuels.
In addition, reduction of greenhouse gases generated by using fossil fuels is also an important issue.

  In order to supply energy stably in such a situation, the use of renewable energy such as sunlight and biomass with less risk of resource depletion and less burden on the environment is receiving more attention.

  Among renewable energies, wind power and biomass are widely used worldwide. In particular, wind power is the most widely used in the world because it can be used at night as long as there is wind, unlike sunlight.

  The principle of wind power generation is to receive the force of wind with the blades of the equipment and convert the energy generated by the rotation of the blades into electrical energy. In addition, the following points can be cited as the advantages of wind power generation.

  The first advantage is that resources are not depleted. Because it uses the natural phenomenon of wind, there is no risk of depleting resources like fossil fuels.

  The second advantage is that it does not emit harmful substances. In thermal power generation, carbon dioxide is generated by burning fossil fuel, and in nuclear power generation, a highly toxic substance called radioactive waste must be treated.

  The third advantage is that it can generate electricity even at night. In solar power generation, it is not possible to generate power at night when the sun is not out due to the principle of converting sunlight into electrical energy.

  The fourth advantage is that the power generation efficiency is relatively high. Wind power generation can convert nearly 40% of the energy of wind to electricity. It can be said that it is higher than other power generation methods.

Another disadvantage of wind power generation is that if the wind speed is unstable, the amount of power generated varies, and the function of the facility stops during a storm like a typhoon and the installation location is limited.
However, since the disadvantages of wind power generation can be compensated by the advantages, expectations for wind power generation are high, and various technologies have been proposed.

For example, Patent Document 1 describes a wind power generator shown in FIG.
That is, the wind turbine generator 501 described in Patent Document 1 includes a windmill rotor 503, and the windmill rotor 503 includes a hub 504 and at least one blade 502 attached to the hub 504.

The wind turbine rotor 503 and the rotating shaft 506 connected to the wind turbine rotor 503 are configured to rotate by wind energy received by the blades 502.
Further, a hydraulic pump 508 is connected to the wind turbine rotor 503 via a rotation shaft 506. In addition, a hydraulic motor 510 is connected to the hydraulic pump 508 via a low pressure oil line 514 and a high pressure oil line 512.

  The hydraulic pump 508 is driven by the rotating shaft 506, and pressurizes the hydraulic oil to generate high-pressure hydraulic oil (high-pressure oil). The high pressure oil generated by the hydraulic pump 508 is supplied to the hydraulic motor 510 via the high pressure oil line 512, and the hydraulic motor 510 is driven by the high pressure oil.

Further, the low-pressure hydraulic oil (low-pressure oil) that has been worked by the hydraulic motor 510 is returned to the hydraulic pump 508 via the low-pressure oil line 514.
A generator 516 is connected to the hydraulic motor 510. Further, at least a part of the rotating shaft 506 is covered with a nacelle 518 installed on the tower 519.

  The rotational energy of the windmill rotor 503 is input to the generator 516 via a hydraulic transmission 505 as a hydraulic machine including the hydraulic pump 508 and the hydraulic motor 510, and electric power is generated in the generator 516.

  However, since the invention described in Patent Document 1 is not an invention based on the idea of increasing the rotation of the rotating shaft based on wind energy, it is not sufficient in terms of improving the power generation capacity, and wind power generation capable of improving the power generation capacity. A device was sought.

  The present invention has been made in view of the above points, and an object of the present invention is to provide a wind turbine generator with improved power generation capability.

  In order to achieve the above object, a wind turbine generator according to the present invention includes a shaft body that includes a longitudinal direction and is rotatable about the longitudinal direction, and a wind power receiver that is attached to the shaft body in a protruding state. A rotating part having a body and being rotatable about the same direction as the longitudinal direction of the shaft body, and extending in a direction substantially orthogonal to the longitudinal direction of the shaft body protruding from the rotating part and coaxial A support plate that can be attached to the body, a side plate that protrudes in a direction substantially perpendicular to the support plate from an edge at a position away from the center of rotation of the support plate in the rotational radius direction, and the side plate adjacent to the side plate. A swing that can be attached to an edge region, which is a region of the support plate, so that one end in the longitudinal direction that extends by connecting the center region of rotation and the same edge region can swing in a direction substantially perpendicular to the longitudinal direction of the shaft body. A rotation stabilization unit having a moving body, and a front protruding from the rotation unit And a power generation possible power generation unit based on the rotation of the shaft.

  Here, wind is applied to the wind power receiver by the rotating portion including the shaft body that includes the longitudinal direction and is rotatable about the longitudinal direction and the wind power receiver that is attached to the shaft body in a protruding state. The added wind force is transmitted to the shaft body, and the shaft body can be rotated.

  Moreover, it is possible to generate power based on the rotation of the shaft body based on the wind force transmitted to the shaft body by the power generation section capable of generating power based on the rotation of the shaft body protruding from the rotation section.

  In addition, there is a support plate that is rotatable about the same direction as the longitudinal direction of the shaft body and that extends in a direction substantially perpendicular to the longitudinal direction of the shaft body protruding from the rotating portion and can be attached to the shaft body. The rotation stabilization unit rotates by the rotation of the shaft body based on the wind force transmitted to the shaft body.

  In addition, a side plate protruding in a direction substantially orthogonal to the support plate from an edge at a position away from the rotation center region of the support plate in the rotational radius direction, and an edge region that is a region of the support plate adjacent to the side plate are rotated. The rotation stabilization unit includes a rotation stabilizing unit having a swinging body that can be mounted so that one end in the longitudinal direction extending between the center region and the edge region can swing in a direction substantially orthogonal to the longitudinal direction of the shaft body. The oscillating body is pressed against the side plate of the rotation stabilization unit by the centrifugal force generated by the rotation of the rotation, and the rotational torque in the side plate and the edge region of the rotation stabilization unit is increased, so that the rotation speed of the shaft body can be increased.

  In addition, a side plate protruding in a direction substantially orthogonal to the support plate from an edge at a position away from the rotation center region of the support plate in the rotational radius direction, and an edge region that is a region of the support plate adjacent to the side plate are rotated. The rotation stabilization unit includes a rotation stabilizing unit having a swinging body that can be mounted so that one end in the longitudinal direction extending between the center region and the edge region can swing in a direction substantially orthogonal to the longitudinal direction of the shaft body. Since the oscillating body is pressed against the side plate of the rotation stabilizing portion by the centrifugal force generated by the rotation of the rotation, the rotation balance can be maintained.

  Further, since the longitudinal length of the oscillating body and the weight of the oscillating body itself contribute to the centrifugal force, it is possible to generate a larger centrifugal force than when the sphere is pressed against the side surface of the rotation stabilizing portion. As a result, the rotational torque can be greatly increased as compared with the case where the sphere is pressed against the side plate of the rotation stabilization unit.

  Further, in the wind turbine generator of the present invention, the oscillating body can accommodate a plurality of weight bodies and is configured to be inclined downward in the vertical direction as it approaches the rotation center region of the support plate. it can.

  In this case, since the oscillating body is inclined, the other end in the longitudinal direction of the oscillating body is located in the vicinity of the shaft body at the time of starting the rotation of the rotating unit and the rotation of the rotation stabilizing unit. It can be reduced and it is difficult for the rocking bodies to interfere with each other.

  Furthermore, in the wind power generator of the present invention, the oscillator includes a planar bottom, a planar longitudinal side wall that projects substantially perpendicularly to the bottom from a pair of edges extending in the longitudinal direction of the bottom, and a longitudinal length of the bottom. A planar short side wall portion projecting substantially perpendicularly to the bottom portion from a pair of edges extending in the short direction which is a direction substantially orthogonal to the direction, and the bottom portion of the long side wall portion, An opening that communicates the inside and the outside is formed in a region surrounded by the end opposite to the connected side and the end opposite to the side connected to the bottom of the short side wall, The weight body may be a hexahedron.

In this case, it is easy to put the weight body into or out of the rocking body.
Moreover, since the weight body is in contact with the bottom, the long side wall portion, and the short side wall portion, the weight body is difficult to move and is stable.

  In the wind power generator of the present invention, the oscillator can be detachably attached to the edge region.

  In this case, the oscillating body can be taken out of the rotation stabilizing portion and the weight body can be replaced.

  Further, the wind power generator of the present invention extends in the same direction as the longitudinal direction of the shaft body, can be disposed at a position farther from the shaft body than the rotating portion and the rotation stabilizing portion, and has a rod shape. A plurality of struts, and a first planar portion that is a planar body extending in the same direction as the longitudinal direction of the shaft body and having at least the same length as the length of the wind power receiver in the same direction as the longitudinal direction of the shaft body, In addition, a plurality of through holes penetrating between one plane of the first plane portion and the other plane facing the one plane are formed in the first plane portion, and the rotating portion and the rotation stability A first windshield plate that can be disposed at a position farther from the shaft body than the control section and can be attached to the column so as to be swingable in a direction substantially perpendicular to the longitudinal direction of the shaft body; The length and the length of the wind receiver extending in the same direction as the longitudinal direction and in the same direction as the longitudinal direction of the shaft A plurality of through-holes having a second plane part, which is a plane body having the same length, and penetrating between one plane of the second plane part and the other plane facing the one plane Is formed in the second plane portion, and can be arranged at a position farther from the shaft body than the rotation portion and the rotation stabilization portion, and in a direction substantially orthogonal to the longitudinal direction of the shaft body. It can be swung and can be mounted on the side of the column opposite to the side where the first windshield is mounted, and it can be mounted on a different column on a substantially perpendicular bisector connecting the two columns. It can be set as the structure provided with the 2nd windshield which can contact with the 1st windshield which was made.

  In this case, the first windshield plate and the second windshield plate attached to a post different from the post to which the first windshield plate is attached swing in a direction substantially orthogonal to the longitudinal direction of the shaft body. In addition, since the first windshield plate and the second windshield plate are in contact with each other on a substantially perpendicular bisector connecting the two support columns, the first windshield plate and the second windshield plate are rotated. The part can be enclosed from the side.

  In addition, since the first windshield plate and the second windshield plate can surround the rotating part from the side, and through holes are formed in the first windshield plate and the second windshield plate respectively, However, it can be used for power generation by applying wind to the wind power receiver through the through-hole while suppressing the amount of air hitting the wind power receiver.

  In addition, the wind power generator of the present invention can be disposed on the upper side in the vertical direction of the rotating unit, and can be rotated around the same direction as the longitudinal direction of the shaft body, and the top plate is opposed to the top plate, A bottom plate that can be arranged vertically below the rotating part and can rotate about the same direction as the longitudinal direction of the shaft body, and faces one edge of the top plate and one edge of the top plate A left side plate that is connected to one edge portion of the bottom plate and that can be disposed at a position farther from the shaft body than the wind power receiver, and the other edge portion that opposes one edge portion of the top plate And one of the left side plate and the right side plate that can be disposed at a position farther from the shaft body than the wind power receiver A left-hand projecting plate that protrudes from the edge and has an inner surface that curves toward the side on which the wind power receiver is located. The right overhanging plate that protrudes from the edge of the right side plate that faces the edge of the left side plate from which the left overhanging plate protrudes, and whose inner surface facing the side where the wind power receiver is located is curved in a convex shape And a pair of top free edges that are substantially orthogonal to the edges of the top plate connected to the left side plate and the right side plate, respectively, and the left side plate and the right side plate, respectively. A structure including a wind tunnel portion in which a pair of openings communicating the inside and the outside is formed in a region sandwiched between a pair of bottom surface free edges that are substantially perpendicular to the edge of the bottom plate can do.

  In this case, the left overhanging plate protrudes from one edge of the left side plate, and the right overhanging plate protrudes from the edge of the right side plate, so there is a left overhanging plate and a right overhanging plate. The area to which the wind hits is increased by that amount, and the opening adjacent to the left and right overhanging plates becomes leeward.

  Further, since the wind blown from the opening adjacent to the left and right overhanging plates swirls by the left overhanging plate and the right overhanging plate, the speed of the wind passing through the internal space of the wind tunnel portion is increased. be able to.

  Further, in the wind power generator of the present invention, the outer surface of the left overhanging plate facing the side opposite to the side where the wind receiver is located is curved in a concave shape, and the side where the wind receiver is located The left side plate facing the opposite side is curved in a convex shape, and the inner side surface of the left side plate facing the wind receiving body is curved in a concave shape, and the left side plate The outer surface of the left side plate and the outer side surface of the left overhanging plate are continuous with each other, and the inner side surface of the left side plate and the inner side surface of the left overhanging plate are continuous with each other, opposite to the side where the wind power receiver is located. The outer surface of the right-hand projection plate facing to the side is curved in a concave shape, and the outer surface of the right side plate facing to the side opposite to the side where the wind power receiver is located is curved in a convex shape, And the inner surface of the right side plate facing the side where the wind power receiver is located is curved in a concave shape, and the outer side surface of the right side plate and the right overhang plate Side are contiguous to each other, and may be configured to inner surfaces of the inner and MigiCho Deban the right side plate are continuous with each other.

  In this case, the edge on the side opposite to the edge to which the left and right overhanging plates are attached becomes windward, and the outer and inner surfaces of the left side plate and the outer and inner sides of the right side plate Since the wind that has flowed along the outer surface and the inner surface is curved, the speed can be increased more than the flat surface, and the curved outer surface of the left and right projecting plates located leeward In addition, a vortex can be generated by hitting the inner surface.

  In addition, since the outer side surface and the inner side surface of the left side plate and the outer side surface and the inner side surface of the right side plate are curved, it is easy to confine the wind in the wind tunnel, and the wind drag can be reduced.

  The wind power generator according to the present invention can improve power generation capacity.

  Moreover, the wind power generator of this invention does not necessarily need to be provided with the support | pillar, the 1st windshield board, and the 2nd windshield board.

  However, if the wind power generator according to the present invention includes the support, the first windshield plate, and the second windshield plate, the first windshield plate and the second windshield plate have the rotating portion from the side. Since the through-holes are formed in each of the first windshield plate and the second windshield plate, wind is applied to the wind power receiver through the through-hole while suppressing the amount of air hitting the wind power receiver even in a storm. Since it can utilize for an electric power generation, it is preferable.

  In addition, the wind power generator of the present invention does not necessarily have a wind tunnel portion.

At this time, since the left overhanging plate 9E and the right overhanging plate 9F exist, the blown-out wind swirls and the speed of the wind passing through the internal space of the wind tunnel portion increases.

  On the other hand, as shown in FIG. 1, since the rotating part 2 is arranged in the wind tunnel part 9, the blowing air hits the first blade 2B, the second blade 2C, and the third blade 2D, This wind force is transmitted to the shaft body 2A, and the shaft body 2A rotates around its longitudinal direction.

Moreover, since the 1st disk part 3 and the 2nd disk part 4 are each attached to the shaft body 2A, the 1st disk part 3 and the 2nd disk part 4 rotate with rotation of the shaft body 2A.

The torque increases, and the rotational speed of the shaft body 2A is increased.
Moreover, since the structure of the 2nd disk part 4 is the same as the structure of the 1st disk part 3, the 2nd disk part 4 also increases the rotational speed of 2 A of shafts similarly.

  The shaft body 2A extends to the power generation unit 8 and is disposed between the N-pole magnet 8A and the S-pole magnet 8B of the power generation unit 8, and is a shaft positioned between the N-pole magnet 8A and the S-pole magnet 8B. Since the conductive coil wire 8C is helically attached to the outer surface of the body 2A, the power generation unit 8 generates power based on the rotation of the shaft body 2A.

  As described above, the wind turbine generator according to the present invention is adjacent to the side plate and the side plate protruding in the direction substantially orthogonal to the support plate from the edge located away from the rotation center region of the support plate in the rotational radius direction. An oscillating body that can be attached to an edge area that is an area of the support plate so that one end in a longitudinal direction extending by connecting the rotation center area and the edge area can oscillate in a direction substantially perpendicular to the longitudinal direction of the shaft body. Since it has a disk portion, that is, a rotation stabilization portion, the oscillator is pressed against the side plate of the rotation stabilization portion by the centrifugal force generated by the rotation of the rotation stabilization portion, and in the side plate or edge region of the rotation stabilization portion. The rotational torque increases, and the rotational speed of the shaft body can be increased.

  Therefore, since the power generation unit can generate power based on the rotation of the shaft body, the wind power generator of the present invention can improve the power generation capacity.
