Description

Technical Field

[0001] The present invention relates to a power generation device using solar light and wind power.

Background Art

[0002] Renewable energy is energy existing in nature such as solar light and wind power, different from fossil fuels. Since carbon dioxide, which is a greenhouse gas, is not emitted in its utilization, power generation using renewable energy can improve global warming. There are solar power generation and wind power generation as power generation using renewable energy.

[0003] Solar power generation is a power generation method that generates electricity from solar light, and utilizes the phenomenon that electricity is generated when sunlight hits a solar panel. Wind power generation is a power generation method that generates power day and night if there is wind power. On the other hand, the power generation amount of solar power generation depends on the weather. Wind power generation may have a decrease in power generation amount depending on the wind direction and wind speed, and is liable to be affected by seasons and climate. Therefore, conventionally, a power generation device that combines solar power generation and wind power generation to ensure a certain amount of power supply every day has been provided (for example, Patent Document 1).

Summary of the Invention

Problems to be Solved by the Invention

[0005] The wind and solar power generation device described in Patent Document 1 has a blade that rotates around a vertical axis and a generator, and an outer frame surrounding the outer circumference of the blade and provided with a bearing that pivotally supports the vertical axis, with a ground-mounted part at the lower end of the outer frame and a support part at the upper end, forming a column-type power generation wind turbine, and multiple such column-type power generation wind turbines are erected at intervals along the perimeter of a rectangular area intended for use for purposes other than power generation, forming a column-type wind turbine group, and a group of solar cells is mounted between the support parts at the upper ends of each column-type power generation wind turbine in the column-type wind turbine group. According to the above-mentioned wind and solar power generation system, the solar cell array and the pole-type wind turbine array can be efficiently combined and installed within the site of installation, making it possible to secure a larger area of ​​the site that can be used for purposes other than power generation. Furthermore, the integrated control unit that controls the power conditioners for wind power generation and solar cell power conditioners mutually compensates for the shortcomings of the solar cell array, such as the increase or decrease in power generation due to changes in sunlight, and the pole-type wind turbine array ceasing to generate power in the absence of wind, thereby achieving more stable power generation.

[0006] However, in modern times, with increasing household electricity consumption and a growing trend in industrial electricity use such as manufacturing, agriculture, and fisheries, there are concerns about electricity shortages. To alleviate this electricity shortage, it is important to increase the self-generation and self-consumption of residential and industrial electricity. The wind and solar power generation system described in Patent Document 1 had the drawbacks that in order to increase the amount of electricity generated to cope with the growing electricity shortage, the installation area had to be large, and solar panels did not generate electricity during the snowy season.

[0007] The present invention aims to solve the above problems and to provide a power generation device that can increase the amount of power generated per unit area. [Means for solving the problem]

[0008] The power generation device of the present invention is a multi-story building consisting of columns on which a vertical-axis wind turbine and generator are arranged, and floors on which solar panels are arranged.

[0009] Furthermore, the solar panels are designed to be tilted. [Effects of the Invention]

[0010] According to the power generation device of the present invention, by stacking power generation devices that combine wind power generation and solar power generation on multiple floors, electricity for residential and industrial use can be secured. Even during snowfall, the solar panels installed on the floors of each level can be prevented from being covered with snow, and by using it in combination with wind power generation, power can be generated 24 hours a day, 365 days a year, regardless of the location, season, or weather. In addition, the amount of power generated per unit area can be increased. As a result, a power generation device that can secure electricity for residential and industrial use can be provided. [Brief explanation of the drawing]

[0011] [Figure 1] This is a front view of the power generation device of the present invention. [Figure 2] This is a plan view of Figure 1. [Figure 3] This is an end view of line AA in Figure 2. [Modes for carrying out the invention]

[0012] This invention enables self-generation and self-consumption of electricity for residential and industrial use. [Examples]

[0013] The power generation device of the present invention will be described with reference to the figures. Figure 1 is a front view of the power generation device of the present invention. Figure 2 is a plan view of Figure 1. Figure 3 is an end view of line AA of Figure 2. The power generation device of the present invention is a multi-story building consisting of columns on which a vertical-axis wind turbine and generator are arranged, and floors on which solar panels are arranged. The power generation system 10 shown in Figures 1 to 3 consists of vertical-axis wind turbines 14a and generators 14b (wind power generation system 14) placed on eight columns 12a to 12h of a multi-story building 12, and solar panels 16 (solar power generation system 16) placed on the floors (floor slabs) 12x and 12y. One wind power generation system 14 is installed on each column 12a to 12h on each floor (except the first floor), and a total of 16 systems are installed in the multi-story building 12. The power generation system 10 consists of wind power generation and solar power generation equipment installed in the same building (same location).

[0014] The multi-story building 12 consists of columns 12a to 12h and floors 12x, 12y, and 12z (12z being the rooftop). The columns 12a to 12h are assumed to be connected by beams (not shown). The floors 12x, 12y, and 12z are assumed to be fixed to the beams. The columns 12a to 12h in Figures 1 to 3 consist of three rod-shaped piles 13a, 13b, and 13c, which are driven into or embedded in the ground to form a triangle. The three piles 13a, 13b, and 13c forming the triangle are connected and fixed by a beam 13d. External wind and sunlight pass through columns 12a to 12h, causing the wind turbine (blades) 14a to rotate and also hitting the solar panels 16. In Figures 1 to 3, the wind power generation device 14 (a vertical-axis wind turbine 14a and a generator 14b) is located inside columns 12a to 12h.

[0015] The solar power generation system 16 consists of solar panels (solar cell modules that convert solar light energy into electricity). In addition, it is assumed to include a power conditioner (a device that converts the DC power generated by the solar cell modules into AC power usable in the house), a junction box that combines the DC wiring from the solar cell modules into a single wire and sends it to the power conditioner, a distribution board, a storage battery, etc. (not shown).

[0016] The wind power generation device 14 consists of a vertical-axis wind turbine 14a and a generator 14b, in which the rotation axis of the wind turbine (blades) is perpendicular to the ground. In addition, it is equipped with devices such as an inverter, controller, and storage battery (not shown) for integrating the generated electricity into the power grid of a house or other building. In Figures 1 to 3, the vertical-axis wind turbine 14a and generator 14b are positioned in the center (inside) of columns 12a to 12h, which are made up of triangularly arranged piles. The wind turbine 14a receives wind, its rotation axis rotates, and the generator 14b generates electricity.

[0017] On the floors 12x, 12y, 12z (12z is the rooftop), solar panels 16 are laid (Figs. 1 to 3). The solar panels 16 on the floors 12x, 12y are provided so as to rotate about one side as an axis (Fig. 3). A wire 18a is attached to the side opposite to the side that serves as the axis of rotation. By operating the wire winder 18 that winds up the wire 18a, the angle (tilt) of the solar panel 16 can be adjusted. For example, in case of strong wind, the solar panel 16 is used in the state of being laid on the floors 12x, 12y. In summer and winter, the installation angle (angle at which sunlight is easily received on the floor surface) of the solar panel 16 is adjusted for use.

[0018] By stacking the power generation devices 10 that combine wind power generation and solar power generation in multiple layers, it is possible to secure the electric power for residential and industrial use. Even during the snowfall period, it is possible to prevent the solar panels 16 installed on the floors 12x, 12y of each floor from being covered with snow, and it is possible to generate electricity 24 hours a day, 365 days a year without being affected by the installation area, seasons, or weather conditions by using it in combination with wind power generation. Also, by making it a power generation device composed of a multi-story building 12, the power generation amount per unit installation area can be increased. Thereby, it is possible to provide a power generation device corresponding to the amount of electric power for residential and industrial use.

[0019] Furthermore, a reflector (not shown) may be attached to the ceiling portion of each floor to increase the reflected light hitting the solar panel 16. Thereby, the power generation efficiency can be enhanced. Also, in the snow-covered area, a snow melting heater (not shown) for melting the snow blown onto the solar panel 16 may be attached. Thereby, it becomes possible to generate solar power during the snowfall period. Also, the electric power generated on each floor during the non-use time zone of electric power is once charged into a large-capacity storage battery (not shown) installed inside the first floor (Figs. 1, 3) or outside, and the charged electric power is used. Thereby, stable electric power can be used.

[0020] (Effect by multi-layerization of power generation device) By creating multi-layered power generation systems, solar panels can generate electricity even during the snowy season in snowy regions, making it easier to find suitable installation locations. Furthermore, since wind strength increases with altitude compared to flat ground, wind power generation is more efficient on upper floors than on lower floors, making it worthwhile to create multi-layered power generation systems in towers. Tower-type power generation systems can be constructed to match the amount of power required, and maintenance and inspection can be carried out without any particular difficulty, making them suitable for installation as industrial power generation systems by both small and medium-sized enterprises and large corporations. For example, by installing it like a bridge over a river, it can generate the necessary electricity while simultaneously revitalizing the hydrogen production industry by electrolyzing river water to produce hydrogen. Furthermore, by installing an antenna and lighting equipment on the top floor, it would be possible to have it function as a radio tower or lighthouse.

[0021] The power generation system shown in Figures 1 to 3 is designed to improve the power generation efficiency per unit area of ​​the entire tower (power generation system) while allowing the first floor to be used as farmland, a parking lot, or a walkway. In addition to selling the generated electricity, installing and storing large-capacity batteries will allow for the construction of power generation towers tailored to the amount of electricity needed for uses such as agriculture, livestock farming, aquaculture, and hydrogen production, thus contributing to the spread of self-generation and self-consumption.
