  Hereinafter, a wind power generator according to an embodiment of the present invention and a power generation facility including the wind power generator will be described in detail with reference to the drawings. In the following description, the positional relationship of each component will be described in principle with reference to the drawings. Further, for convenience of explanation, the drawings show the structure of the invention simplified, or exaggerated or omitted when necessary. Accordingly, each component is not limited to the size and shape shown in the drawings, and can be implemented by increasing or decreasing the size of each component as necessary. The design can be changed. Furthermore, the present invention is not limited to this, and can be implemented with other various devices added or modified / omitted.

  FIG. 1 is a front view showing an appearance of a wind turbine generator according to an embodiment of the present invention.

  As shown in FIG. 1, the wind turbine generator 10 according to this embodiment includes an upper support plate 110, a lower support plate 120, a shaft member 130 fixed between the upper support plate and the lower support plate, and a shaft member. The rotating member 140 is configured to be rotatably installed on the shaft 130.

  The upper support plate 110 forms the upper structure of the wind power generator 10, and the lower support plate 120 forms the lower structure of the wind power generator 10. The upper support plate 110 and the lower support plate 120 are configured by plate members having a predetermined thickness, and perform a role of supporting the remaining components of the wind turbine generator 10 by being fixed to the outside. Although FIG. 1 shows that the upper support plate 110 and the lower support plate 120 are configured by original plate-shaped members, this is merely an example, and can be configured in various shapes depending on the installation position.

  The upper support plate 110 and the lower support plate 120 serve to support the entire structure of the wind turbine generator. Therefore, it is preferable that the upper support plate and the lower support plate are fixed by a frame structure fixed outside so that the installation state can be firmly maintained even when the wind blows strongly. As shown in FIG. 1, the upper support plate 110 is fixed to the upper frame 20, and the lower support plate 120 is fixed to the lower frame 30. The upper frame 20 and the lower frame 30 are frame structures that are firmly installed in a separate external structure. In this way, the upper and lower ends of the wind power generator 10 are fixed by the external frames, so that a strong installation structure can be maintained even when exposed to an external environment such as a strong wind.

  The shaft member 130 and the rotating member 140 are provided between the upper support plate 110 and the lower support plate 120, and generate electric energy by using the kinetic energy of wind provided from the outside, that is, moving air. It is. The shaft member 130 is composed of a cylindrical rod member installed in the vertical direction, and is fixed between the upper support plate 110 and the lower support plate 120 (see FIG. 3). As shown in FIG. 1, the rotating member 140 is configured such that the shaft member 130 can rotate around the shaft using the kinetic energy of wind provided from the outside.

  Here, the rotating member 140 includes a body part 141, an upper flange 142 and a lower flange 143 installed at both ends of the body part 141, and a blade part 150 installed along the outside of the body part 141. .

  The body portion 141 is configured by a cylindrical member that extends long along the length direction of the rotating member 140. A hollow is formed in the body portion 141 along the length direction to form a space in which the shaft member 130 is accommodated. Further, at least one bearing is formed between the inner wall of the body portion 141 of the rotating member 140 and the outer surface of the shaft member 130, and can rotate with the friction minimized.

  An upper flange 142 and a lower flange 143 made of plate members are provided on the upper and lower stages of the body part 141, respectively. The upper flange 142 and the lower flange 143 are configured to rotate relatively when the rotating member 140 rotates while facing the upper support plate 110 and the lower support plate 120, respectively. At this time, bearings are also installed between the upper flange 142 and the upper support plate 110 and between the lower flange 143 and the lower support plate 120, respectively, and can be configured to rotate while minimizing frictional resistance during rotation.

  The blade part 150 is configured to protrude to the outside of the body part 141, and wind kinetic energy is transmitted to the wind power generator 10 while the wind provided from the outside is applied to the blade part 150. The blade part 150 includes a plurality of fan members 151 and a fixing member 152 that fixes the fan member to the body part. Hereinafter, the blade part will be described in more detail with reference to FIG.

  FIG. 2 shows a part of the blade portion of the wind turbine generator in FIG. As shown in FIGS. 1 and 2, the blade portion 150 is configured to include a plurality of fan members 151, and each fan member 151 is configured to have a curved surface that is convex outward with respect to the rotation axis. The Therefore, when wind flows in the direction of the wind power generator, the wind does not immediately pass, but the kinetic energy of the wind can be sufficiently transmitted while flowing along the internal curved surface of the fan member 151.

  As shown in FIG. 1, the fan member 151 has a shape twisted in the vertical direction. Specifically, the fan member 151 is inclined upward in a certain direction like a spiral shape so that the curved surface structure surrounds the shaft member 130 with respect to the lower stage, and extends upward. Therefore, even if the number of the fan members 151 is small, the kinetic energy of the wind provided in various directions can be sufficiently transmitted, and not only the horizontal velocity component of the wind but also the vertical direction. This speed component can also be used for wind power generation, so that the power generation efficiency can be improved.

  Here, the fan member 151 may have various widths. In the embodiment shown in FIG. 1, the rotation direction width of the upper stage of the fan member 151 is formed wider than the width of the lower stage. Generally, since the flow velocity is larger in the upper part than the lower part of the wind power generator due to the friction between the wind and the installation surface, when the upper part is wide, the kinetic energy of the wind with a large flow speed should be used. There is an advantage that you can. On the other hand, when installing so as to use the exhaust air provided upward from the lower side of the wind turbine generator, it is possible to configure the fan member so that the lower width of the fan member is wider than the upper width. . In addition, in consideration of the environment in which the wind turbine generator is installed, it is possible to make the middle width of the fan member wider than the upper and lower widths, so that the fan member forms a certain width in the vertical direction. It is also possible to configure.

  As shown in FIG. 2, such a fan member can include a fan frame 151a and a fan cover 151b. The fan frame 151a is formed of a member having relatively high rigidity to form a skeleton structure of the fan member 151, and is configured to prevent the shape from being changed due to wind resistance during rotation. The fan cover 151b is made of a lighter material than the fan frame 151a, and forms a shielding surface in the space between the fan frames 151a. As described above, the fan member 151 includes the fan frame 151a and the fan cover 151b, and despite having high resistance to wind, by minimizing its own weight, It is configured so that the rotational speed is induced.

  On the other hand, such a fan member 151 is fixed to the body portion 141 by a plurality of fixing members 152. The fixing member 152 is made of a material having excellent rigidity, and has one end fixed to the body portion 141 and the other end fixed to the fan member 151. Therefore, when the kinetic energy of wind power is transmitted to the fan member 151, the body part 141 and the fan member 151 can rotate integrally with the shaft member 130 about the shaft.

  As shown in FIG. 1, in this embodiment, a rotating member 140 including two fan members 151 is shown, but this is only an example, taking into consideration the environmental conditions and rotational efficiency in which the wind turbine generator is installed. Various changes can be made.

  FIG. 3 is a cross-sectional view showing a cross section of the wind turbine generator in FIG. 1, and for convenience of explanation, the rotating member shows only the body part excluding the fan member. The wind turbine generator according to the present embodiment is arranged so that the magnet member 160 and the coil 170 are opposed to each other. A system in which a magnetic field is changed while the permanent magnet 160 and the wound coil 170 move relatively with the rotation of the rotating member 140, and thereby a current (or electromotive force) is induced in the wound coil. Can produce electrical energy.

  First, as shown in FIG. 3, the upper flange 142 and the lower flange 143 of the rotating member 140 are provided with magnet members 160. In addition, the upper support plate 110 and the lower support plate 120 are provided with coils 170 wound at positions corresponding to the magnet members of the upper flange 142 and the lower flange 143. Therefore, electric energy can be produced while an electric current is induced in the coil 170 wound along with the rotation of the rotating member 140.

  Specifically, in this embodiment, as shown in FIG. 3, the upper support plate 110 and the lower support plate 120 are configured to form recess portions in which the upper flange 142 and the lower flange 143 are accommodated, respectively. Further, permanent magnets 160 are disposed on the upper flange 142 along the upper surface and the side surfaces, respectively, and coils 170 wound on the bottom surface and the inner peripheral surface where the recess portions are formed are disposed on the upper support plate 110. . Similarly, permanent magnets 160 are disposed on the lower flange 143 along the lower surface and side surfaces, respectively, and coils 170 wound on the upper surface and the inner peripheral surface where the recess portions are formed are disposed on the lower support plate 120. The

  However, this is only an example. When the upper support plate and the lower support are not provided with a separate recess portion and are configured to be laminated so as to face the upper flange and the lower flange, permanent magnets and coils. It is also possible to configure so that each is installed on the mutually opposed surfaces.

  Further, permanent magnets and coils for producing electrical energy during rotation can be installed not only at both ends of the rotating member, but also at the rotating member and the shaft member. Specifically, as shown in FIG. 3, a coil 170 is wound outside the shaft member 130. At this time, the coil can be wound in a form exposed on the outer peripheral surface of the shaft member, and is wound inside the outer peripheral surface of the shaft member in consideration of being installed outside. It can also be configured to be installed in the interior. A plurality of permanent magnets 160 are formed on the inner surface of the body portion of the rotating member 140. Accordingly, when the rotating member 140 rotates, the permanent magnet 160 of the rotating member 140 and the coil 170 wound around the shaft member 130 rotate relatively, and current is induced in the wound coil to produce electric energy. can do.

  Thus, in the wind power generator 10 according to the present embodiment, electrical energy is generated by the upper support plate 110 and the upper flange 142 on the upper side by the rotation of the rotating member 140, and between the rotating member 140 and the shaft member 130 at the center. In this structure, electric energy is generated at the lower side, and electric energy is generated between the lower support plate 120 and the lower flange 143 on the lower side. At this time, although not separately shown in the drawing, a line capable of transmitting electric energy is provided inside the shaft member 130, and the electric energy generated by the upper support plate 110 or the lower support plate 120 is transmitted to the line. The electric energy transmitted to the one side via the, and collected at the upper side, the center, and the lower side can be collected and provided to the outside.

  As described above, according to the present embodiment, in this embodiment, not only electrical energy is produced at both ends of the rotating member 140 but also a shaft member 130 fixed inside the rotating member 140 is provided. A structure capable of maximizing power generation efficiency in an environment in which the rotating member rotates similarly is provided by using the large area where the member 130 and the rotating member 140 are opposed to each other to produce electric energy.

  However, in this embodiment, the upper flange 142, the body portion 141, and the lower flange 143 of the rotating member 140 that is rotated are provided with the magnet member 160, and the upper support plate 110, the lower support plate 120, and the Although the description has been made centering on the configuration in which the coil 170 is wound around the shaft member 130, this is merely for easily installing a line for transmitting the generated power, and the magnet member is installed in the above-described embodiment. The coil can be arranged so as to be arranged at a part or all of the portion to be arranged, and the magnet member can be installed at the installation position of the coil corresponding to this.

  Hereinafter, with reference to FIG.4 and FIG.5, it demonstrates concretely with respect to the structure in which the wind power generator concerning a present Example is installed.

  FIG. 4 is a front view showing a structure in which a plurality of wind turbine generators are installed. Although the single wind power generator 10 described above can be installed, a plurality of the wind power generators 10 are installed so that a sufficient amount of electric energy can be produced. As shown in FIG. 4, an upper frame 20 and a lower frame 30 fixed to the outside (for example, another installation surface such as the ground) are included. Here, the plurality of wind turbine generators 10 may have a structure in which each upper support plate 110 is installed on the upper frame 20 and each lower support plate 120 is installed on the lower frame 30. In this case, even when a strong resistance acts on any one of the wind turbine generators, the installation structure of the other wind turbine generators installed on the same upper frame 20 and lower frame 30 plays a role of stably maintaining the installation state. In order to accomplish, a strong fastening structure can be constructed.

  However, in the case of FIG. 4, a plurality of wind power generators are arranged side by side, but the installation structure is not limited to this, and the upper frame and the lower frame are each a mesh structure in a lattice form. By comprising, each wind power generator can be arrange | positioned in various positions.

  FIG. 5 shows a power generation facility in which the wind power generator of FIG. 1 is installed. As described above, the wind power generator according to the present embodiment, unlike the conventional wind power generator, has a simplified configuration that rotates around the vertical direction, so it can be used in urban areas and existing buildings. It is also possible to install. Furthermore, since the shape of the fan of the rotating member can be rotated using not only the wind provided in the horizontal direction but also the kinetic energy of the wind provided in the vertical direction, the exhaust pipe of the constructed facility Electric energy can be produced by utilizing it in the vertical direction like exhaust air exhausted through the air.

  A power generation facility 40 shown in FIG. 5 includes a building 50 and a wind power generator 10 installed on the upper side of the building 50. Here, the building 50 is a variety of buildings such as a building, a residential facility such as a house, a factory, a barn, a greenhouse, or a farm, or a newly built building, or a building that has already been built. It is also possible to use. In such a building, at least one exhaust pipe 51 for collecting air exhausted from the internal space and exhausting it to the outside is formed. As shown in FIG. A vertical pipe line can be constructed.

  On the other hand, a plurality of wind turbine generators 10 are installed above the building 50, and at least one of the wind turbine generators can be arranged above the exhaust pipe 51 of the building. In this case, the corresponding wind power generator 10 can also produce electric energy using natural wind provided from the outside, and produce electric energy using exhaust wind exhausted from the building 50. It is also possible. Therefore, compared to conventional wind power generation methods that rely only on natural winds, it is possible to produce electrical energy using exhaust air even in adverse weather conditions, minimizing deviations in power generation due to the external environment. There is an advantage that you can.

  Here, in the case of the wind turbine generator arranged on the upper side of the building, unlike the wind turbine generator shown in FIG. 1, the rotation direction width of the lower stage of the fan member 151 can be formed wider than the width of the upper stage. It is. In such a structure, it is more advantageous to rotate the fan member using the exhaust air provided from below. However, the shape of the fan member can be variously changed in consideration of the dependence of natural wind and exhaust wind used for power generation.

  In the wind power generator shown in FIG. 1, the lower frame and the lower flange are made of original plate-shaped members that are not provided with separate openings. However, the wind power generator that uses exhaust air is provided from the lower side. It is also possible to configure the lower frame and the lower flange to include at least one opening (not shown) so that the exhaust air can easily pass in the direction of the fan member.

  On the other hand, as shown in FIG. 5, a separate auxiliary fan 60 is provided on the upper side of the building. The auxiliary fan 60 is installed at a position adjacent to the wind turbine generator, and is installed to provide wind power in the direction of the wind turbine generator. Generally, in the case of a wind turbine generator, many loads are applied for the initial rotation operation. Therefore, even if a natural wind of a size that can continuously rotate the fan member 151 in a state in which the rotation operation of the fan member 151 is performed, the fan member 151 rotates in a state in which the fan member 151 is stopped. Hard to get started. Therefore, this power generation facility can be configured to contribute to the initial rotation operation of the wind power generator by providing wind power using the separate auxiliary fan 60.

  Such an auxiliary fan 60 is configured to be able to actively rotate by receiving power from a separate power source. Further, the auxiliary fan 60 has a wide width in the rotational direction of the fan member (in the case of FIG. 5, below the fan member) so that the wind force provided from the auxiliary fan can act as a large moment on the fan member of the wind turbine generator. It is preferably arranged to provide wind power in the lateral direction).

  In this embodiment, the auxiliary fan is configured to be located on one side of the fan member in a configuration separate from the wind power generator, but this is only an example, and the auxiliary fan is arranged to be located on the lower side of the fan member. Alternatively, the auxiliary fan can be integrated with the wind power generator. For example, by fixing to the lower flange or lower frame of the fan member of the wind power generator, it is possible to operate so as to contribute to the initial rotation when the fan member is initially driven.

  Furthermore, in the present embodiment, the configuration in which a separate auxiliary fan is provided so that the initial rotation of the fan member of the wind turbine generator is easily performed, but in addition, a motor that can provide rotational power to the fan member is added. It is also possible to provide such a configuration that the motor is driven only at the initial rotation of the fan member to start the rotation of the fan member.

  In the case of such a power generation facility, it is possible to produce electric energy using the natural wind and exhaust wind with the vertical wind power generator according to the present invention. There is an advantage that you can. It is also possible to provide electrical energy produced from the facility to an external facility or sell the electrical energy.

  In the above, it demonstrated with respect to the wind power generator which produces an electrical energy using natural wind and exhaust wind, and a power generation facility including the same. Such hydroelectric generators can be configured with small-scale equipment so that they can be applied to exhaust facilities of small buildings like single houses, and can be applied to large-scale facilities such as skyscrapers or factories. It can also be configured with a large-scale device that can.

  Furthermore, the above-described embodiment is merely an example for embodying the present invention, and can be modified and applied in various other ways. Accordingly, the scope of rights claimed in the present invention is not limited to the matters described in the embodiments, but must be determined by whether or not the features described in the claims are implemented.
