Description

The purpose of the present invention is to rationally configure a module rotation system for use in solar sharing or the like to reduce installation costs and maintenance costs.

In order to promote the spread of solar power generation, the total cost of introduction is 10,000 times the kWh unit price of power sales. For example, in order to implement a power selling unit price of 20 yen / kWh that is lower than the average power purchase price, one target is to reduce the introduction cost to about 200,000 yen / kW or less.
Solar power generation is priced by mass production of solar grade silicon with a purity of around 6N (99.9999%) to 7N (99.99999%) from the use of a piece of semiconductor grade silicon (purity 99.999999999% (11N) or higher), which is a material such as IC. As the power generation method becomes the backbone of the “society consisting only of renewable energy”, the future development is beginning to be expected more and more. .
Under such circumstances, in order to prevent severe natural disasters as well as the fossil fuel life problem, which will be exhausted in the next 200 years, we aim to reduce its carbon dioxide emissions to zero and rapidly reduce its usage. This has emerged as the most important issue, and it is necessary to rationalize solar power generation.

For solar power generation, a large area of land is required, starting with the roof of the house, followed by mega-solars using the idle land of industry and primary industry, and then Japan. Since the purchase price is quite high from the world's common sense, foreign capital that can be procured at a low price has cut down satoyama, destroyed the mountain, and reclaimed fallow land as gravel land. At this point, solar power generation has become a “natural energy that destroys nature,” and many local governments feel the necessity for environmental assessment and are considering regulatory regulations. If megasola is made on a flat ground, the entire site must be paved to prevent the panel from being buried due to overgrowth of weeds and vines, weeding sheets are spread, and herbicides must be sprayed frequently. To use it as a solar power generation site, it is necessary to cut down forests, destroy mountains, destroy nature, and take measures against weeds after installation. Increased barren land will appear.

Solar power generation has become cheaper than all power generation methods, and it has become an eternal means of acquiring energy as an alternative to power generation using nuclear power and fossil fuels. We have to secure vast land for power generation in a coexisting form.
Among them, as a method of overcoming the shortcomings, “Solar Sharing” can be used as a method of raising the support and installing the solar power generation module in the air to generate solar power in the air and using the land below for its original purpose. The concept has gained wide public support and has finally entered the stage of dissemination.

However, a photovoltaic module (panel) is installed several meters above the ground to withstand many natural disasters such as huge typhoons, heavy snow, heavy rain, ash fall, rainfall, and earthquakes, as well as installation costs and maintenance inspections. There is a remaining problem of further reducing all costs such as costs and renewal costs.

In Patent Document 1, in order to reduce the wind pressure load, the module is held at a predetermined inclination by a spring, and in a strong wind, the structure is configured to be horizontal by the force of the wind against the force of the spring. Structurally with respect to the fact that the spring cannot be kept completely horizontal due to the component force of the spring extending and returning to the wind streamline, and that the wind pressure load is kept to a minimum by oscillating due to fluctuations in wind speed. Was insufficient.
In Patent Document 2, since the actuator is fixed to the gantry, when the module angle is changed due to snow or the like, the reaction force for changing works in the direction of disassembling the gantry, and the gantry such as a temporary pipe assembled by friction bonding There are structural weaknesses in which the mounting member deforms due to the joining member coming off or changing position, and because many modules rotate at once, the operating load of the actuator exceeded the set value due to some malfunction Sometimes, it is troublesome to find the cause of the problem, and there is a problem that costs for maintenance and inspection are increased. Further, in order to move a large number of modules at the same time, there are problems that the number of steps for assembling the interlocking rods and rotating members increases and the installation cost is increased, and part of the modules vibrates due to strong wind due to the overall play of the link mechanism. In addition, since the interlocking link is used for the mechanism, when the rotation angle of the module exceeds approximately 90 degrees, the force required for the rotation is remarkably increased, and the mechanical efficiency is lowered as a problem.

As a method of changing the inclination angle of the module horizontally in order to improve wind resistance, a plurality of elongated holes are provided in the module fixing member so that the inclination angle of the module can be changed manually.

Since the rotating mechanism is included in the module mounting member, the increase in cost to maintain the wind resistance performance in the event of a storm such as a huge typhoon is minimized, so small-scale solar for home use that can be maintained at any time It can be expected to be applied to sharing.

FIG. 1 is an overall perspective view of the first embodiment of the present invention. FIG. 2 is a typical perspective view of an L-shaped module support member. FIG. 3 is a view showing a normal inclination state of the module 3 viewed from the side. FIG. 4 is a diagram showing a horizontal state of the module 3 viewed from the side. FIG. 5 is a view showing a mounting state of the module 3 as viewed in the longitudinal direction of the beam. FIG. 6 is a perspective view showing a module fixing member embodiment having another L-shaped cross section. FIG. 7 is a perspective view of another module fixing member implementation plan having an L-shaped cross section.

  A part of the member that fixes the module to the beam is provided with one or two elongated holes and the fixing bolt with the beam is loosened so that the module inclination angle can be changed.

FIG. 1 is a perspective view of a first embodiment of the present invention, in which a module mounting beam 2 is formed in a grid according to the size of the module 3, and as shown in FIG. The shape fixing member 1 is used to fix the beam 2 and the bolt 4. The L-shaped fixing member 1 and the module 3 are fastened using a module holding member 5.

In order to make it easier to receive sunlight except during strong winds, it is tilted and fixed as shown in FIG.

  When approaching a strong typhoon where the wind speed is expected to be 30 m / sec or more, it is recommended to loosen the bolts and level them manually as shown in FIG. 4 to fix them manually to minimize the wind pressure load.

As shown in FIG. 6, it is possible to level by opening a round hole at the horizontal setting position, and at the time of changing to the horizontal level, the bolt can be pulled out once, leveled, and then assembled again. Moreover, since the holes of the metal fittings to be used are different on the left and right sides, it is desirable to provide both holes to be used on the left and right to make the members common.

  As shown in FIG. 7, by making all the bolt holes for mounting the beams into long holes, the degree of freedom is increased, and the width of change in the module inclination angle can be increased.

  This device is not limited to farming-type photovoltaic power generation, it is effective in using all land as a solar power generation land in three dimensions, and as a means of obtaining eternal renewable energy for humankind that can coexist with nature without destroying nature. It becomes an indispensable means. In this sense, the term “solar sharing” is inevitably created as a term with a broader meaning than “agricultural farming” and has begun to spread worldwide.

In the low latitude tropics, the growth of crops is hindered by too strong sunlight, and hunger, poverty, and looting are likely to occur. However, due to the widespread use of this device, abundant temperate crops can be obtained. It is highly likely that many problems can be solved if new farming can be developed.

Solar power generation can be expected to really promote a natural energy society through the widespread use of this material, which is inexpensive and resistant to natural disasters.

Japan's annual power consumption is approximately 100 billion kWh / year, but if it is calculated as 40 kW / counter of power generation per area of solar sharing, the required area is only 2.5 million hectares, and the total area of farmland is 4.6 million hectares If it becomes a society that is sufficiently small compared with, and obtains infinite power from farmland, agriculture will become an attractive industry for young people as an attractive industry, and the village can be revived by the establishment of young people.

In order to prevent global warming, in order to build a decarbonized society as soon as possible, solar sharing will further coexist with nature and make use of characteristics that are strong against natural disasters, and this plan will improve wind resistance at a low cost of materials. There is expected.
