Description

Renewable Energy Equipment

The present disclosure relates to a renewable energy utilization apparatus, and more particularly, to a renewable energy utilization apparatus using wind and / or sunlight (solar heat).

Renewable energy is a future energy source for a sustainable energy supply system that converts existing fossil fuels or converts renewable energy including sunlight, water, geothermal energy, wind, and bioorganisms. Environmental issues, such as GHG issues, require a paradigm shift from conventional fossil energy to renewable energy, and renewable energy globally to meet the reduction targets of Business As Usual (BAU). Prevalence is on the rise.

By the way, in order to use solar light, wind power, etc., a large installation area is needed. In addition, due to the low density of energy collected, the expected effect is insufficient and economic efficiency is low.

For example, according to Non Patent Literature 1 (CHOI Choi, Ho-Nam Jang, Prediction of Small Wind Turbine Power Generation in Roofs of Urban High-rise Buildings, Journal of The Korean Society for New and Renewable Energy, Vol. Wind speed (unit m / s) in, Daejeon, Gunsan, Busan, Mokpo, Gangneung are shown in Table 1 below.

	10 m	30 m	50 m
Seoul	2.5	3.7	4.2
Incheon	2.6	4.0	4.5
Daejeon	2.0	3.2	3.6
Gunsan	2.6	3.8	4.2
Busan	3.0	4.4	4.8
Mokpo	3.7	4.9	5.4
Gangneung	3.1	4.3	5.8

FIG.

1 to 3, the renewable energy utilization apparatus 100 of the present embodiment includes a wind power module 110, a solar module 150, and a support 190.

The renewable energy utilization apparatus 100 of the present embodiment may be installed on, for example, a rooftop of a building such as a single house, an apartment, a building, a mountain ridge, or a plain. Of course, the installation place is not limited to this.

The wind power module 110 includes a cylindrical tower 111 and a plurality of wings 112.

Cylindrical tower 111 is a cylindrical structure that is erected perpendicular to the bottom surface (10). Cylindrical tower 111 may have, for example, a diameter of several tens of mm to several tens of meters (D1 in FIG. 3). The diameter D1 of this cylindrical tower 111 does not limit this embodiment.

The cylindrical tower 111 performs a function of accelerating the wind entering the wind power module 110 as described below. The cylindrical tower 111 may be formed of a plastic material such as polycarbonate or acrylic. Furthermore, the cylindrical tower 111 may be formed of a transparent plastic material. Of course, the material of the cylindrical tower 111 is not limited thereto, and may be formed of an opaque plastic material or a metal or nonmetal material.

The cylindrical tower 111 is installed to be fixed to the central column 119 by the plurality of first fixed beams 113. The central column 119 is located at the central axis of the cylindrical tower 111. The central column 119 is installed to be perpendicular to the bottom surface 10. One end of each of the plurality of first fixed beams 113 is fixedly coupled to the central pillar 119, and the other end of each of the plurality of first fixed beams 113 extends in the radially outward direction from the central pillar 119. The cylindrical tower 111 is fixed to the other end of each of the plurality of first fixed beams 113.

The plurality of blades 112 are disposed on the outer circumferential surface of the cylindrical tower 111 and rotatably installed on the central pillar 119. That is, the plurality of wings 112 are rotatably installed about the central axis of the cylindrical tower 111. For example, as shown in FIG. 2, two flanges 115 are rotatably coupled to the top and bottom of the central column 119. The two flanges 115 may be provided with bearings or the like to reduce friction with the central column 119. One end of each of the plurality of second fixed beams 114 is fixedly coupled to each of the two flanges 115, and the other end of each of the plurality of second fixed beams 114 extends in a radially outward direction to form a cylindrical tower 111. Part of the outer circumference is exposed outside. The plurality of wings 112 are coupled to portions exposed to the outside of the outer circumferential surface of the cylindrical tower 111 of the plurality of fixed beams 114. The plurality of blades 112 are disposed to be spaced apart from the outer circumferential surface of the cylindrical tower 111 so as not to touch the outer circumferential surface of the cylindrical tower 111 when rotating about the center column 119.

The plurality of wings 112 may have a shape extending in the longitudinal direction (ie, the vertical direction) of the cylindrical tower 111. Moreover, the width | variety (D2 of FIG. 3) of the some wings 112 is smaller than the diameter D1 of the cylindrical tower 111 with respect to the radial direction of the cylindrical tower 111. As shown in FIG. That is, the cylindrical tower 111 has a diameter D1 larger than the width D2 of the some blade 112 so that the acceleration effect by the cylindrical tower 111 mentioned later may be acquired.

The plurality of wings 112 may have, for example, a semi-cylindrical shape that is long in the vertical direction. The semi-cylindrical shape of the plurality of wings 112 is exemplary, but is not limited thereto. As another example of the shape of the plurality of wings 112, the plurality of wings 112 may have a curved shape in which the cross section is formed in an aerodynamic design. As another example of the arrangement of the plurality of wings 112, the plurality of wings 112 may be installed to be inclined in the vertical direction. The plurality of wings 112 may be provided with six, for example, as shown in FIGS. 1 to 3, but this is merely an example, and the number of the wings 112 is not limited thereto.

The plurality of wings 112 may be fixedly coupled to the other ends of the plurality of fixed beams 114. As another example, the angles of the plurality of vanes 112 may be variably coupled to the other ends of the plurality of fixed beams 114 so as to correspond to the wind speed. The variable manner of the plurality of wings 112 may be made manually or automatically. A fixed or variable manner of coupling of the plurality of wings 112 is known in the art.

The wind turbine 140 may be located inside the cylindrical tower 111. The wind turbine 140 may be located at the top, the middle, or the bottom of the cylindrical tower 111. The wind turbine 140 is coupled to interlock with rotation of at least one of the two flanges 115 (eg, the lower flange 115, as shown in FIG. 2). Interlocking of the wind turbine 140 and the flange 115 may be made in a known manner, for example, gears, belts. For example, a gearbox may be provided between the flanges 115 and 115 and the wind power generator 140, so that the rotation speed of the blade 112 may be constant by using an increase gear or a reduction gear of the gearbox. In addition, a brake system may be additionally provided to stop the rotation of the blade 112 when the wind speed is too strong. During operation of the renewable energy utilization apparatus 100, the plurality of wings 112 rotates along the outer circumferential surface of the cylindrical tower 111 by the wind, converts the wind energy contained in the wind into rotational energy, accordingly the flange 115 ) Will also rotate. The wind turbine 140 produces electrical energy by converting rotational kinetic energy of the flange 115 into electrical energy.

Since the cylindrical tower 111 rotates only the plurality of blades 112 in the fixed state of the renewable energy using device 100 of the present embodiment, the portion of the mechanical device rotating in the renewable energy using device 100 is lightened.

The solar module 150 may be located below the wind power module 110. The solar module 150 may include a support plate 151 and a solar panel 152 provided on the support plate 151. The solar module 150 may be manufactured in a circular flat plate shape. The width of the solar module 150 may be wider than the cross-sectional area of the wind power module 110. As described above, since the cylindrical tower 111 is formed of a transparent plastic material, since the sunlight may reach a portion covered by the wind power module 110, the solar panel may be formed on the entire region of the solar module 150. 152 may be laid. Of course, for the purpose of reducing the manufacturing cost, the solar panel 152 may not be disposed in a region directly below the wind module 110 in the solar module 150. As such, when the solar panel 152 is not disposed in a region directly below the wind power module 110, the cylindrical tower 111 may be formed of an opaque material. Circular flat plate shape of the solar module 150 is an example, the present invention is not limited thereto. As another example, the photovoltaic module 150 may be manufactured in a polygonal flat plate shape such as square, rectangle, hexagon, or the like.

The renewable energy utilization apparatus 100 of the present embodiment may further include a wind collecting plate 160. The wind collecting plate 160 may be located above the wind power module 110. The collecting plate 160 performs a function of collecting wind to allow more wind to enter the wind power module 110, as described below. In addition, since the wind collecting plate 160 performs a function of guiding the wind to the wind power module 110, it may also prevent turbulence generated on the rooftop.

The collecting plate 160 may be formed of a transparent plastic material such as transparent polycarbonate or transparent acrylic, and may be manufactured in a circular flat plate shape. An upper surface of the collecting plate 160 may be coated with a reflection ring. The width of the wind collecting plate 160 may be wider than the cross-sectional area of the wind power module 110. For example, the wind collecting plate 160 may be manufactured in the shape of a circular flat plate having the same width as the solar module 150. Circular plate shape of the wind collecting plate 160 is an example, the present invention is not limited thereto. As another example, the wind collecting plate 160 may be made of a polygonal flat plate such as square, rectangle, hexagon, or the like, or a plate formed in a whole or part of a curved surface, or a three-dimensional sculpture. Or, it may be formed in a shape suitable for the place where the renewable energy utilization apparatus 100 is installed. For example, when the renewable energy using device 100 is installed on the roof of a building such as an apartment or a building, the wind collecting plate 160 may have a roof shape or may be replaced by some structure of the building. Furthermore, the wind collecting plate 160 is further provided with a guide structure (eg, wings, ribs, etc.) for guiding the direction of the wind in order to guide the wind better to the wind power module 110. It could be.

Depending on the location where the renewable energy utilization apparatus 100 of the present embodiment is installed, the desired output of the wind power module 110 may be achieved by accelerating the wind speed of the cylindrical tower 111 without the collecting plate 160. Therefore, the wind collecting plate 160 may be omitted.

The support unit 190 supports the wind power module 110, the solar module 150, and the wind collecting plate 160. The support unit 190 may include a plurality of support bars 191 that are vertically erected, and a plurality of support beams 192 that are horizontally installed. One end of the plurality of support rods 191 is fixed to the bottom surface 10 by the first fixing part 191a. A second fixing part 191b is provided at a position spaced a predetermined distance from one end of the plurality of support rods 191 and is coupled to the outer circumference of the solar module 150. Accordingly, when the renewable energy utilization apparatus 100 is installed outside the building, the solar module 150 is fixed to the bottom surface 10 by the support 190 so as to prevent the flooding by rainwater. It can be installed spaced apart. The other ends of the plurality of support bars 191 are coupled to one ends of the plurality of support beams 192, respectively. The other ends of the plurality of support beams 192 are placed in the horizontal direction and fixedly coupled to the center side 119. The collecting plate 160 is fixed to a known fastening means such as a bolt, an adhesive, and the like, while being placed on the upper portion of the plurality of support beams 192.

Renewable energy using device 100 of the present embodiment has been described as an example in which the support 190 is fixed to the wind module 110, the solar module 150, and the wind collecting plate 160 at the same time, for example It is not limited. Of course, at least a portion of the wind power module 110, the solar module 150, and the wind collecting plate 160 may be installed by separate supporting means. For example, when the renewable energy using device 100 is installed on the roof of the building, the wind collecting plate 160 may be supported by a separate structure of the building.

Renewable energy using device 100 of the present embodiment may further include a storage battery (not shown) for storing the electrical energy produced by the wind power module 110 and the solar module 150. The storage battery may be located inside the cylindrical tower 111, under the solar module 150, or in a separate place. The storage battery makes it possible to use the electrical energy produced in the solar module 150 during the day time.

Next, the operation of the renewable energy utilization apparatus 100 of the present embodiment will be described.

4 is a graph showing an output curve of a commercially available wind power generator according to an example. Referring to FIG. 4, the commercial wind power generator according to the example does not substantially generate wind speed under 3 m / s, and at a wind speed of 3 m / s or more, the output gradually increases, and the wind speed is output at about 15 m / s or more. It can be seen that this is saturated. That is, it can be seen that the wind speed of the commercial wind turbine according to an example is output about 80% or more of the maximum output at 12 m / s or more. In addition, even if the wind speed is about 8 m / sec can be seen that the commercial wind turbine according to an example produces only about 40% of the maximum output electricity.

As described above with reference to Table 1, the annual average wind speed is about 2 ~ 5 m / s in the urban environment of our country, the wind speed is very insufficient to secure the rated output of commercially available wind power generators in the urban environment of Korea. have.

In addition, it is well known that the wind power density is given by Equation 1 below.

In Equation 1, P represents wind density (unit W / m ² ), ρ represents the density of the air, v represents the wind speed. According to Equation 1, since the amount of electricity generated by the wind turbine is proportional to the third power of the wind speed v, it can be understood that by accelerating the wind speed v, the electric energy that can be generated per unit area can be increased. .

The renewable energy using device 100 of the present embodiment secures the air flow rate using the wind collecting plate 160 and accelerates the wind speed using the cylindrical tower 111, thereby securing the rated output of the commercial wind power generator, To increase energy generation efficiency.

First, the wind speed acceleration by the cylindrical tower 111 will be described with reference to FIG. 5. 5 is a diagram for explaining wind speed acceleration by the cylindrical tower 111. In FIG. 5, only the cylindrical tower 111 and the wind 20 are illustrated for convenience of description. Referring to FIG. 5, when the wind 20 proceeds toward the cylindrical tower 111, since the wind 20 flows on the outer circumferential surface of the cylindrical tower 111, the vicinity of the outer circumferential surface of the cylindrical tower 111 (A). In the wind 20 can be understood to pass through a narrow passage. On the other hand, the wind 20 can be approximated to the uncompressed fluid. Since the flow rate per unit time is the same in region A or region B, the wind 20 in region A will have to pass faster than the wind 20 in region B. That is, in the vicinity of the outer circumferential surface (A) of the cylindrical tower 111 will be understood that the wind 20 is accelerated compared to the area (B) away from the cylindrical tower (111). The acceleration of the wind 20 can be explained by the Venturi effect or Bernoulli principle, the wind speed is changed depending on the Reynolds number, but the wind speed is accelerated 1.5 to 2.5 times. As described with reference to FIGS. 28 to 34 to be described later, the indoor simple wind tunnel experiment conducted with the models of 1/2, 1/3, 1/5, and 1/6 was also confirmed in the rooftop experiment.

In addition, since the cylindrical tower 111 has a cylindrical shape, it is not affected by the wind direction. For example, the wind direction often changes from time to time, but the renewable energy utilization apparatus 100 of the present embodiment does not need additional components corresponding to the change in the wind direction.

Next, the wind speed acceleration by the wind collecting plate 160 will be described with reference to FIGS. 6 and 7.

FIG. 6 illustrates a wind flow when the renewable energy utilization apparatus 101 without the wind collecting plate is installed on the roof of the building, and FIG. 7 illustrates the renewable energy utilization apparatus 100 including the collecting plate 160 on the roof of the building. Shows wind flow when installed. For convenience of description, side winds and vortices are omitted in FIGS. 6 and 7.

Referring to FIG. 6, the laminar wind 21 blowing in the horizontal direction in the city center creates an upward wind 22 rising vertically on the outer wall of the building. Such an upward wind 22 may have, for example, a wind speed of about twice the speed or more with respect to the wind speed of the laminar wind 21. The vertical rising wind 22 merges in a predetermined area above the roof while drawing a parabola on the roof of the building 11 while maintaining a wind speed of approximately twice the speed or more. The renewable energy utilization device 101 is disposed near the path of the wind 23 where the vertical rising winds 22 join, that is, near the rooftop edge of the building 11.

As described above with reference to FIG. 4, when the commercially available wind power generator does not secure a predetermined wind speed, power generation efficiency is very low. Renewable energy using device 100 of the present embodiment is installed on the roof of the building 11, the wind speed is relatively fast, by using the cylindrical tower 111 to accelerate the wind speed, which is required at the rated output of the commercially available wind power generator Wind speed can be secured. For example, as shown in Table 1, the annual average wind speed at 50 m above the ground shows 4 to 5 m / s. Such wind speed alone cannot secure the rated output of a commercially available wind power generator. When the wind speed is accelerated by approximately 2.5 times, the wind speed reaches around 12 m / s or more, thereby securing a rated output of a commercially available wind power generator. 50 m above the ground level corresponds to the height of the roof of a 15-story apartment or building, which is about 80 m or more above sea level, for example, on the roof of a 15-story apartment in the city. It can be understood that by installing the A can obtain the rated output of the commercially available wind power generator.

In addition, as illustrated in FIG. 7, the wind collecting plate 160 may be provided in the renewable energy utilization apparatus 100 of the present embodiment. The collecting plate 160 focuses the wind 24 toward the wind module 110 toward the upper side of the cylindrical tower 111 joining the vertical rising wind 22. The wind 24 focused by the wind collecting plate 160 may be interpreted as passing through a narrow passage, and thus, the wind 24 may be interpreted as being accelerated by the wind collecting plate 160 in a principle similar to that described with reference to FIG. 5. Can be. On the contrary, referring to FIG. 6, in the renewable energy utilization apparatus 101 having no wind collecting plate, the wind 23 directed upwardly of the cylindrical tower 111 is applied to the wind power generation of the wind power module 110. It passes without making a contribution.

As described above, the renewable energy utilization apparatus 100 of the present embodiment may further accelerate the wind 24 by the wind collecting plate 160, so that even if the wind is installed on the roof of the low-rise building 11, Although somewhat low, the acceleration effect of the wind speed by the cylindrical tower 111 and the acceleration effect of the wind speed by the wind collecting plate 160 may be added to secure a rated output of a commercially available wind power generator. Of course, even if there is no wind collecting plate 160, if the wind speed can be secured enough, the collecting plate 160 may be omitted.

On the other hand, the renewable energy using device 100 of the present embodiment is to increase the space efficiency by installing the solar module 150 on the bottom surface of the wind module 110.

FIG. 8 is a schematic side view of the renewable energy utilization apparatus 200 according to another embodiment of the present invention, and FIG. 9 illustrates a bottom structure of the top plate employed in the renewable energy utilization apparatus 200 of FIG. 8. Drawing.

8 and 9, the renewable energy utilization apparatus 200 of the present embodiment includes a wind power module 110, a solar module 150, a refractory wind collecting plate 260, and a support 190. The remaining components except for the refractive collecting plate 260 are substantially the same as the components of the renewable energy utilization apparatus 100 described with reference to FIGS. 1 to 3, and thus, the differences will be mainly described.

The refraction collecting plate 260 is located on the upper portion of the wind power module 110, and collects the wind of the rising air, and performs a light collecting function to increase the luminous flux incident on the solar module 150 by refracting the sunlight. .

The refractive collecting plate 260 is formed of a transparent plastic material such as transparent polycarbonate or transparent acrylic, and may be manufactured in a circular flat plate or polygonal shape. An upper surface of the refractive collecting plate 260 may be coated with a reflection ring. The width of the refractory wind collecting plate 260 may be wider than the cross-sectional area of the wind power module 110. For example, the refractive collecting plate 260 may be manufactured in the shape of a circular flat plate or a polygonal flat plate having the same width as that of the solar module 150.

As shown in FIG. 9, the deflection collecting plate 260 includes a transparent plate 261 and a plurality of inverted pyramid-shaped prisms 262 formed on the bottom surface of the transparent plate 261. The plurality of prisms 262 may be densely provided so that there are no gaps over the entire bottom surface of the transparent plate 261. Of course, the present invention is not limited thereto, and the prism 262 may not be formed in a portion of the bottom surface of the transparent flat plate 261.

In the present embodiment, the prism 262 has an inverted pyramid shape as an example, but the present invention is not limited thereto. For example, when the surface of the transparent plate 261 is called XY plane, the prism 262 has a prism shape extending in the X direction or the Y direction, or a shape in which a plurality of prisms extending in the circumferential direction are concentric. May have Alternatively, an optical pattern for focusing sunlight, such as a condenser lens or a diffraction pattern, may be formed on the bottom or upper surface of the refractive collecting plate 260. The shape and arrangement of the prism 262 of the refraction collecting plate 260 or other optical refraction elements may be geometrically shaped to improve aesthetics.

In the present embodiment, a case in which the prism 262 is formed on the bottom surface of the transparent flat plate 261 is described as an example, but is not limited thereto. For example, the prism 262 may be formed on the top surface of the transparent plate 261 or may be formed on both the top and bottom surfaces of the transparent plate 261.

Next, the operation of the renewable energy utilization apparatus 200 of the present embodiment will be described. The remaining operations except for the additional solar focusing function by the refraction collecting plate 260 are substantially the same as the operation of the renewable energy using device 100 described with reference to FIGS. 1 to 7, and thus, the differences will be mainly described.

FIG. 10 illustrates a state in which sunlight is incident on the renewable energy utilization apparatus of FIG. 9, and FIGS. 11 and 12 illustrate incidence paths of sunlight depending on the height of the sun.

Referring to FIG. 10, the winter solar elevation angle may be very low, such as 30 degrees. The solar light 50 having such a low elevation angle is incident at an angle to the solar module 150 installed parallel to the floor of the building in the absence of the refractory collecting plate 260. That is, when there is no refractive collector plate 260, the effective cross-sectional area of the light beam of the solar light 50 incident on the solar module 150 is given by the following equation (2).

Here, S ₀ represents the cross-sectional area of the solar module 150, θ represents the angle of incidence of the solar light 50, and S _eff represents the effective cross-sectional area of the light beam of the solar light 50 which substantially contributes to photovoltaic power generation. The incident angle θ of the sunlight 50 has a relationship of adding 90 degrees to the solar elevation angle.

11 and 12, when the incident surface 261a (that is, the upper surface of the transparent plate 261) is incident on the incidence angles θ1 and θ2, the bottom surface of the transparent plate 261 is formed. It is emitted downward through the prism 262. At this time, although the path of the light emitted by the angle of the incident angles θ1 and θ2 is slightly different, as shown in FIGS. 11 and 12, the light is generally refracted closer to the direction orthogonal to the bottom surface of the refraction collecting plate 260.

As shown in Equation 2, the lower the solar altitude angle, that is, the larger the incident angle θ of the sunlight 50, the lower the light beam effective cross-sectional area S _eff . Accordingly, the refractive collecting plate 260 may increase the effective cross-sectional area of the light beam of the solar light 50 by refracting the incident light 50 to be more perpendicular to the solar module 150.

Furthermore, when the incident angle θ of the sunlight 50 becomes large, that is, when the sunlight 50 is obliquely incident on the deflection collector 260, the plurality of prisms 262 totally reflects inside the deflection collector 260. Will prevent this from happening.

As described above, the refraction collecting plate 260 adjusts the angle of the prism so that the emission angle is emitted almost vertically wherever the position of the sun is located, so that the solar module 150 more when the heating energy consumption in winter is high. Large amounts of solar radiation can be obtained to maximize energy efficiency.

13 is a schematic side view of a renewable energy utilization apparatus 300 according to another embodiment of the present invention.

Referring to FIG. 13, the renewable energy utilization apparatus 300 of the present embodiment includes a wind power module 110, a solar module 350, a refractive wind collecting plate 260, and a support 190. Instead of the refraction collecting plate 260, a collecting plate (160 of FIG. 1) may be provided or omitted. Renewable energy using device 300 of the present embodiment may be understood to include a solar module 350 in place of the solar module 150 in the renewable energy using device (100, 200) of the above-described embodiments. . The other components except for the solar module 350 are substantially the same as those of the renewable energy utilization apparatuses 100 and 200 of the above-described embodiments, and thus, the differences will be mainly described.

The solar module 350 may include a collector 351, a pipe 352, a storage tank 353, a heater 354, and a pump 355.

The collector 351 may include a light collecting part in which a flow path through which the fluid circulates is formed, and a reflecting plate reflecting sunlight in order to concentrate solar heat in the flow path of the light collecting part. The collector 351 heats the fluid inside the collector 351 using solar heat. The collector 351 may be, for example, a compound parabolic concentrator (CPC) collector, but is not limited thereto. The fluid may, for example, be water or thermal oil. The heated fluid may be stored in the storage tank 353 through the pipe 352. In addition, the hot fluid stored in the storage tank 353 may be used for heating while passing through the heater 354 through the pipe 352. The heater 354 is an example, and a well-known hot water using apparatus using hot water may be used in place of the heater 354. The fluid stored in the storage tank 353 and the fluid via the heater 354 may be re-introduced into the collector 351 by the pump 355 and circulated. The solar module 350 may further include an auxiliary boiler in preparation for the fluid not being heated to a sufficient temperature.

In the present embodiment, a configuration having one closed circuit that directly uses the fluid heated in the collector 351 is described as an example, but is not limited thereto. For example, the solar module 350 may include a heat exchanger that heat-exchanges the fluid heated in the collector 351 with a second fluid having another property, and a second heater using the second fluid.

Referring to FIG. 14, the renewable energy utilization apparatus 400 of the present embodiment includes a wind power module 410, a solar module 150, a wind collecting plate 160, and a support 190. Instead of the collecting plate 160, a refractive collecting plate 260 of FIG. 8 may be provided or omitted. The renewable energy utilization apparatus 400 of the present embodiment replaces the wind turbine module 410 of the rotating structure in place of the wind turbine module 110 of the fixed structure in the renewable energy utilization apparatus 100, 200, 300 of the above embodiments. It can be understood to use. The other components except for the wind power module 410 are substantially the same as those of the renewable energy utilization apparatuses 100, 200, and 300 of the above-described embodiments, and thus, the differences will be mainly described.

The wind power module 410 includes a cylindrical tower 411 rotatably coupled to the central pillar 119, and a plurality of wings 412 directly coupled to the outer circumferential surface of the cylindrical tower 411.

The configuration in which the cylindrical tower 411 is rotatably coupled to the central column 119 may employ a known method. For example, two flanges 415 are rotatably coupled to the top and bottom of the central column 119, and the cylindrical tower 411 is coupled to the flange 415 by a plurality of fixed beams 413. Could be. In this case, the cylindrical tower 411 may be formed of a light material, for example, a polycarbonate or a plastic material such as acrylic, in consideration of the strength of the wind power. Furthermore, the cylindrical tower 411 may be formed of a transparent plastic material. As another example, the case in which the cylindrical tower 411 is formed of a metal or nonmetal material is not excluded. The cylindrical tower 411 may be supported only by the flange 415 without contacting the upper surface of the solar module 150 spaced apart.

On the other hand, the plurality of wings 412 may have a semi-cylindrical shape that is long in the vertical direction, for example. As another example of the shape of the plurality of wings 412, the plurality of wings 412 may have a curved shape in which the cross section is formed in a hydrodynamic design. The plurality of wings 412 may be extended to be coupled to the outer circumferential surface of the cylindrical tower 411 in the vertical direction, or may be coupled to be extended to be inclined in the vertical direction. Each of the plurality of vanes 412 may be divided into a plurality of rows in the longitudinal direction on the outer circumferential surface of the cylindrical tower 411 and arranged in a row.

The plurality of wings 412 may be fixedly coupled to the outer circumferential surface of the cylindrical tower 411, or may be variably coupled so that the angle of the wings is adjustable. The variable manner of the plurality of vanes 412 may be manual or automatic. For example, six wings 412 may be provided as illustrated in FIG. 14, but this is merely an example, and the number of wings 412 is not limited thereto.

Next, the operation of the renewable energy utilization apparatus 400 of the present embodiment will be described.

15 is a view for explaining the operation of the renewable energy utilization apparatus 400 of the present embodiment. 15 illustrates only the cylindrical tower 411 and the plurality of vanes 412 in the wind power module 410 of the renewable energy utilization apparatus 400 of the present embodiment.

Referring to FIG. 15, when the wind 20 is blown toward the cylindrical tower 411, the wind 20 flows on the outer circumferential surface of the cylindrical tower 411. Since the plurality of wings 412 are attached to the cylindrical tower 411, when the plurality of wings 412 are subjected to rotational force by the wind 20, the cylindrical tower 411 rotates together with the plurality of wings 412. Done. Meanwhile, in FIG. 15, area C is an area in which the traveling direction of the wind 20 and an outer circumferential surface of the cylindrical tower 411 move in the same direction, and area D is an area in which the traveling direction of the wind 20 and the outer circumferential surface of the cylindrical tower 411 move. This is an area in which the moving direction is reversed. In the region C, the outer circumferential surface of the cylindrical tower 411 and the wind 20 move in the same direction, so the wind 20 has a relatively high speed. In the region D, the outer circumferential surface of the cylindrical tower 511 and the wind 20 Since the opposite to each other the wind 20 will have a relatively slow speed. This effect can be further improved power generation efficiency because the speed of the air in the C region a little faster than when the cylindrical tower 111 of the above-described embodiment is fixed.

Renewable energy utilization apparatuses 100, 200, 300, and 400 of the embodiments described with reference to FIGS. 1 to 15 will be described by taking cylindrical towers 111 and 411 having a cylindrical shape having a circular cross section as an example. However, it is not limited thereto.

16 illustrates a wind turbine module 510 used in a renewable energy utilization apparatus 500 according to another embodiment of the present invention.

Referring to FIG. 16, the wind module 510 of the present embodiment includes a polygonal tower 511 and a plurality of wings 512 coupled thereto.

The polygonal tower 511 may have a cylindrical shape having a polygonal cross section. For example, polygonal tower 511 may have a hexagonal cross section, as shown in FIG. 16. Of course, the cross-sectional shape of the polygonal tower 511 is not limited to this, and may be a hexagon, a octagon, an octagon, or the like.

The plurality of wings 512 may be installed at corners at the outer circumferential surface of the polygonal tower 511. As another example, the plurality of wings 512 may be installed on a plane on the outer circumferential surface of the polygonal tower 511.

The polygonal tower 511 may be rotatably coupled to the central column (119 of FIG. 14). For example, one end of a plurality of fixed beams 513 is fixedly coupled to each of the flanges 515 in the inner hollow of the polygonal tower 511, and the other end of each of the plurality of fixed beams 513 is formed in the polygonal tower 511. Coupled to the side, the flange 515 may be rotatably coupled to the central column (199 of FIG. 14).

Although the outer circumferential surface of the polygonal tower 511 has a polygonal column shape as in the present embodiment, as described above, the wind (20 in FIG. 15) flows along the outer circumferential surface of the polygonal tower 511, and is approximately referred to FIG. 15. It will be understood by those skilled in the art that the same effects as described above can be obtained.

In addition, the present embodiment has been described taking a case where the plurality of wings 512 are installed on the outer circumferential surface of the polygonal tower 511, the polygonal tower 511 is fixed to the center column (119 in Fig. 1), Only the wing 512 may be rotatably coupled with respect to the center column 119.

FIG. 17 is a schematic perspective view of a renewable energy utilization apparatus 600 according to another embodiment of the present invention, and FIG. 18 schematically illustrates a bottom plate 650 of the renewable energy utilization apparatus 600 of the present embodiment. It is a figure and FIG. 19 is the figure which showed the cylindrical tower 611 of the renewable energy utilization apparatus of this embodiment in the state reversed.

17 to 19, the renewable energy utilization apparatus 600 of the present embodiment includes a wind power module 610, a lower support plate 650, a wind collecting plate 160, and a support 190. Instead of the collecting plate 160, a refractive collecting plate 260 of FIG. 8 may be provided or omitted. Renewable energy using device 500 of the present embodiment may be understood that the guide structure is further adopted in the lower portion of the wind module 410 in the renewable energy using device 400 of the embodiment with reference to FIGS. 14 to 15. That is, the remaining components except for the wind power module 610 and the lower support plate 650 are substantially the same as the components of the renewable energy utilization apparatus 400 of the above-described embodiment, and thus the differences will be mainly described.

The wind power module 610 includes a cylindrical tower 611 rotatably coupled to the central column 119. A plurality of wings 412 are directly coupled to the outer circumferential surface of the cylindrical tower 611. The configuration in which the cylindrical tower 611 is rotatably coupled to the central column 119 may employ a known method. For example, two flanges 415 are rotatably coupled to the top and bottom of the central column 119, and the cylindrical tower 411 is coupled to the flange 415 by a plurality of fixed beams 413. Could be. Rotating supports 617 may be provided at the lower periphery of the cylindrical tower 611.

The lower support plate 650 includes a lower plate 651 positioned below the wind power module 610 and a bottom guide rail 655 provided on the lower plate 651. The lower plate 651 may be a solar module 150 (FIG. 1), a solar module 350 (FIG. 13), or may be a simple flat plate. Alternatively, the lower plate 651 may be a bottom surface on which the renewable energy utilization device 600 is installed.

The bottom guide rail 655 is a member that guides the rotation of the cylindrical tower 611 while supporting the load of the cylindrical tower 611. That is, the rotary support 617 provided at the lower periphery of the cylindrical tower 611 is rolled along the bottom guide rail 655 provided in the lower plate 651. The bottom guide rail 655 may have a circular groove shape provided at a portion of the lower plate 651 facing the lower end of the cylindrical tower 611, or may have a protruding shape.

The cylindrical tower 611 is rotatably installed around the central column 119. As the rotational speed of the cylindrical tower 611 increases, the cylindrical tower 611 tends to be shaken and vibration may occur. The shaking or vibration of the cylindrical tower 611 causes noise, and also worsens the durability of the device. Further, the shaking or vibration of the cylindrical tower 611 causes friction between the cylindrical tower 611 and the lower plate 651 to lower the power generation efficiency. In addition, the larger the size of the cylindrical tower 611, the greater the load on the cylindrical tower 611, the vibration or vibration of the cylindrical tower 611, the friction with the lower plate 651 will lower the power generation efficiency and the noise is intensified. Can be. In the renewable energy utilization device 600 of the present embodiment, the cylindrical tower 611 is rotated by providing a bottom guide rail 655 on the rotary support 617 and the lower support plate 650 at the lower periphery of the cylindrical tower 611. It can play a role of suppressing the shaking or vibration generated when. In addition, when the rotary support 617 is a wheel, friction with the lower plate 651 generated when the cylindrical tower 611 rotates can be reduced.

The wheel-shaped rotating support 617 is merely an example, and there may be various modifications. As another example, the rotary support 617 may be a bearing device. As another example, the rotary support 617 and the bottom guide rail 655 may be a magnetic levitation device for guiding the cylindrical tower 611 while floating in the lower plate 651 in a magnetic levitation manner.

20 is a perspective view illustrating a wind power module 710 used in the renewable energy utilization apparatus 700 according to another embodiment of the present invention.

Referring to FIG. 20, the wind turbine module 710 of this embodiment includes a cylindrical tower 711 and a plurality of wings 712 coupled thereto.

Cylindrical tower 711 may be cylindrical towers 411 and 611 of the embodiments described above. The configuration in which the cylindrical tower 711 is rotatably coupled to the central column 119 may employ a known method. For example, two flanges 415 are rotatably coupled to the top and bottom of the central column (119 of FIG. 1), and the cylindrical tower 711 is flanged 415 by a plurality of fixed beams 413. To be combined. At the bottom of the outer circumference of the cylindrical tower 711, as in the embodiment with reference to FIGS. 17 to 19, a guide structure may be provided.

At least a portion of the plurality of wings 712 may be installed in an inclined direction 713 on the outer circumferential surface of the cylindrical tower 711. At this time, the inclined direction 713 of the plurality of wings 712 is a direction in which at least a portion of the surface on which the wings 712 face the wind faces downward. Due to the inclined arrangement of the wings 712, the partial wind force of at least a portion of the wind received by the wings 712 is directed upward. This upward wind force component of the wind serves to reduce the load of the cylindrical tower (711). The larger the size of the cylindrical tower 611, the greater the load on the cylindrical tower 611, the shaking of the cylindrical tower 611 or friction with the lower plate 651 may reduce the power generation efficiency and noise, etc., By reducing the load of the cylindrical tower 711 using the inclined arrangement of the blades 712 as described above, it is possible to reduce the decrease in power generation efficiency and the occurrence of noise.

The plurality of vanes 712 may be installed in the cylindrical tower 711 so that the inclination angle may be changed manually or automatically in response to the wind speed. Of course, the plurality of wings 712 may be installed in the cylindrical tower 711 so that the inclination angle is fixed. Increasing the angle of inclination of the plurality of blades 712 increases the force of upward wind force to reduce the shaking, vibration or friction of the circular tower 711, but weakens the force to rotate the circular tower 711 Can be. On the contrary, when the inclination angle of the plurality of blades 712 is reduced, the force of wind force upward is reduced, and the effect of reducing the shaking, vibration, and friction of the circular tower 711 is slightly reduced. Rotating force can be large. Therefore, the inclination angle of the plurality of blades 712 may be set in consideration of both the wind speed and the power generation efficiency.

FIG. 21 is a schematic perspective view of a renewable energy utilization apparatus 800 according to another embodiment of the present invention, and FIG. 22 is a view of an intermediate portion of the cylindrical tower 811 in the renewable energy utilization apparatus 800 of FIG. 21.

Renewable energy using device 800 of the present embodiment is different from the renewable energy using device 600, 700 of the embodiment with reference to Figures 17 to 20, there is a difference in the rotatable support structure of the wind power module 810, The other components except for these are substantially the same as those of the renewable energy utilization apparatuses 600 and 700 of the above-described embodiment, and thus the description will be mainly focused on differences.

The wind power module 810 includes a cylindrical tower 811 and a plurality of wings 812 directly coupled to the outer circumferential surface of the cylindrical tower 811.

The upper circumference of the inner circumferential surface of the cylindrical tower 811 is formed in a circular shape. The cylindrical tower 811 may be rotatably supported by the first rotating supports 831 at a plurality of points around the top of the inner circumferential surface. The first rotating supports 831 can be, for example, wheels or bearing devices. The first rotating supports 831 are supported by the fixed beams 834 extending from the lower support plate 850 or the center pillar 119.

The upper circumference of the inner circumferential surface of the cylindrical tower 811, which is in contact with the first rotating supports 831, may be smoothly processed. Alternatively, a rail may be positioned around the upper end of the inner circumferential surface of the cylindrical tower 811 to engage the first rotational supports 831. Instead of the cylindrical tower 811, a polygonal tower may be employed, in which case the upper periphery of the inner circumferential surface of the polygonal tower that abuts against the first rotating supports 831 may be smoothly processed into a circle or may be formed with the first rotating supports 831. An interlocking rail is provided.

As shown in FIG. 22, teeth 813 are formed around the inner circumferential surface of the middle portion of the cylindrical tower 811 with respect to the longitudinal direction (ie, the vertical direction) of the cylindrical tower 811. That is, the cylindrical tower 811 has a kind of gear structure in which teeth 813 are formed around the inner circumferential surface of the middle portion.

Inside the cylindrical tower 811, a wind generator 840 is engaged with the teeth 813. The wind power generator 840 is supported by the fixed beams 835 extending from the lower support plate 850 or the central column 119. The wind turbine 840 may include a gearbox including gears 841 and 842 that mesh with the teeth 813. During operation of the renewable energy utilization device 800, the plurality of wings 812 rotates the cylindrical tower 811 by the wind, and when the cylindrical tower 811 is rotated, the teeth provided on the inner peripheral surface of the cylindrical tower 811 Cogwheel 841 engaged with 813 rotates, and thus, wind power generator 940 converts rotational kinetic energy of cylindrical tower 811 into electrical energy to produce electrical energy.

The second rotary support 832 may be further installed inside the cylindrical tower 811. The second rotating supports 832 may rotatably support the cylindrical tower 811 at a plurality of points around the inner circumferential surface of the middle portion of the cylindrical tower 811. The inner circumference of the cylindrical tower 811 supported by the second rotating supports 832 may be a portion where the teeth 813 are provided. In this case, the second rotatable supports 832 may be cog wheels meshing with the cog 813. Of course, the second rotatable supports 832 may be provided at a portion where the teeth 813 are not provided around the inner circumference of the cylindrical tower 811 (that is, at a position different from the height of the teeth 813).

FIG. 25 is a perspective view illustrating the wind power module 1010 used in the renewable energy utilization apparatus according to another embodiment of the present invention, and FIG. 26 is a cross-sectional view of an intermediate portion of the wind power module 101 of FIG. 25.

25 and 26, the wind turbine module 1010 according to the present embodiment includes a cylindrical tower 1011 and a plurality of wings 1012 coupled thereto.

Cylindrical tower 1011 may be cylindrical towers 411, 611, 711, 811 of the embodiments described above. The configuration in which the cylindrical tower 1011 is rotatably coupled to the central column 119 may employ a known method. For example, two flanges 415 are rotatably coupled to the top and bottom of the central column (119 of FIG. 1), and the cylindrical tower 1011 is flanged 415 by a plurality of fixed beams 413. To be combined. At the lower end of the outer periphery of the cylindrical tower 1011, as in the embodiment with reference to FIGS. 17 to 19, a guide structure is provided, or as shown in the embodiment with reference to FIG. Of course, it can be prepared.

The plurality of wings 1012 may be coupled to the outer circumferential surface of the cylindrical tower 1011 by a variable coupling member 1013 such as a hinge, so that the wing angle may be changed. Here, the wing angle means an angle at which the wing 1012 is inclined with respect to the mounting surface of the cylindrical tower 1011, as shown in FIG. 27. The variable coupling member 1013 may include an elastic member 1014 so that the plurality of wings are inclined closer to the direction of the wind as the wind strength increases so that the renewable energy utilization apparatus is not damaged by the strong wind. . A well-known means can be employ | adopted as the elastic member 1014 which supports the some blade 1012 by an elastic force. Such an elastic member 1014 may be, for example, a torsion spring. The wing angle according to the strength of the wind can be adjusted by appropriately designing the elastic modulus of the elastic member 1014.

27 is a view for explaining the operation of the wind turbine module 1010 according to the present embodiment. In FIG. 27, the lengths of the arrows representing the winds 20-1, 20-2, and 20-3 represent the strength of the wind. Referring to FIG. 27, as the strength of the winds 20-1, 20-2, and 20-3 increases, the wings 1012 are inclined obliquely toward the wind direction. That is, the wing 1012 has a wing angle α1, α2, α3 with respect to the mounting surface of the cylindrical tower 1011, the higher the intensity of the wind (20-1, 20-2, 20-3) , Can become smaller gradually. For example, when the wind speed of the wind 20-1 is less than approximately 20 m / s, the wing angle α1 is kept as large as possible with respect to the direction of the wind 20-1, thereby maximizing the efficiency of wind power generation. It is done. If the wind speed of the wind 20-2 exceeds approximately 20 m / s, the wing angle α2 gradually decreases with respect to the direction of the wind 20-1, so that the wind speed of the wind 20-3 is approximately 50 m / s. When the m / s is exceeded, the wing angle α3 is reduced to the maximum, thereby minimizing the influence of the wind on which the wing 1012 abuts, so that the renewable energy utilization device may not be damaged by very strong wind.

In the present embodiment, the wing angle is automatically changed by the elastic member 1014, but the present invention is not limited thereto. It is also possible to manually adjust the angle of the blade 1012, and also to allow the angle of the blade 1012 can be adjusted using a separate power source (for example, a motor).

At least a portion of the plurality of wings 1012 may be installed in an inclined direction on the outer circumferential surface of the cylindrical tower 1011 as described with reference to FIG. 20.

In the present embodiment, a structure in which the cylindrical tower 1011 is rotated is described as an example, but is not limited thereto. For example, as in the example described with reference to FIGS. 1 to 13, the cylindrical tower 111 is fixed and the plurality of vanes 112 are rotated to the center column 119 by the fixed beam 114 and the flange 115. Of course, it can be applied even if the possible combination. For example, the variable coupling member 1013 and the elastic portion 1014 of the present embodiment may be applied to the coupling structure of the plurality of wings 112 and the fixed ratio 114. In addition, even when the cylindrical tower 111 is fixed and the plurality of wings 912 are coupled to the first to third circular rings 931, 932, 933 as in the example described with reference to FIGS. 23 and 24, In the coupling structure of the wing 912 and the first to third circular rings 931, 932, and 933, the variable coupling member 1013 and the elastic part 1014 of the present embodiment may be applied.
