Description

  The present invention relates to a solar power generation facility using an aerial wire that does not hinder farming as much as possible while utilizing farmland and the like. In particular, the present invention enables “double-cropping of rice and power generation” as will be clarified later.

  In Japan, which faced the Great East Japan Earthquake and the Fukushima Daiichi nuclear power plant accident that accompanied it, there is a need for a means of providing alternative energy in place of the nuclear power plant.

  In order to obtain alternative energy, a business has been developed in which a large number of structures are fixed in a large area and a photovoltaic power generation module is attached to these structures, as represented by mega solar. However, if it does in this way, it will be necessary not only to ensure a large area only for power generation, but also to build a large-scale structure, and a great cost is required.

  On the other hand, Japan is facing a super-aging population in which elderly people over the age of 65 account for a quarter of the population, and not only protect elderly people with social security systems, but rather healthy elderly people It is desirable to create a workplace where you can work for about 4 hours, where you can work for about 4 hours and earn income, so that you can take a social role and take measures to make your life worthwhile.

  As a technique for overcoming such a difficult situation, the present inventor has to work mainly on farmers and healthy elderly people on farmland (rice fields, fields, pastures, etc.) and perform solar power generation. I am pondering.

  The current problem is summarized as follows.

  First, the safety myth of nuclear power generation was destroyed by the accident at the Fukushima Daiichi Nuclear Power Station following the Great East Japan Earthquake, and nuclear power generation lost its trust and was forced to stop.

  Secondly, fossil fuels are burned at thermal power plants to make up for the power shortage caused by the shutdown of the nuclear power plant. However, if this is done, significant negative effects such as a large amount of global warming gas and trade deficits due to fuel imports will occur. Unavoidable.

  Thirdly, in addition to the problem of the aging of farmers, the future of Japan's agriculture or rural villages is in danger as negotiations on TPP proceed.

  As a measure to solve these problems all at once, the present inventor proposes “double-cropping between rice and power generation” and discloses a specific technique for realizing “double-cropping between rice and power generation” in the present application. The inventor recognizes that double cropping between rice and power generation is a social project if the amount of power generated by this method exceeds 1% (1 trillion yen on a monetary basis) in farmland, etc. I expect it will be done.

  The reason for the “double cropping of rice and power generation” is that if the farmland is used for solar power generation and the farmland is a rice field, both rice and electricity can be produced on the farmland.

Patent Document 1 (Japanese Patent Application Laid-Open No. 2003-318430) discloses a technique in which a solar cell module is foldably connected with a hinge and both sides of the solar cell module are locked to a pair of wire ropes.

  However, according to Patent Document 1, if this is installed on farmland, the sunshine is significantly hindered and the effect on harvesting is unavoidable.

  If the prior art is used on farmland, it will greatly hinder farm work. In other words, according to the conventional technology, “double-cropping of rice and power generation” cannot be performed.

  Then, an object of this invention is to provide the solar power generation facility by the air wire which can generate electric power, using a wire, suppressing the yield reduction in farming.

  The photovoltaic power generation facility using the aerial wire according to the first aspect of the present invention is provided with a pair of mounts that stand up to a predetermined height from the ground and that are opposed to each other with a predetermined distance in a certain direction, and that have a certain direction on the upper surfaces of the pair of mounts. A first wire guide is provided on one side facing and a second wire guide is provided on the other side, and a pair of wires guided in parallel to the first wire guide and the second wire guide are bridged between the pair of mounts. A tension adjuster for adjusting the tension of the pair of wires is provided on at least one of the pair of mounts, each of the pair of wires is passed through the pair of pipes, and a hook of the pair of cloth plates is engaged at a predetermined position of the pair of pipes. The solar cell module is fixed to the pair of cloth plates.

  In this configuration, a pair of wires are spanned between the pair of mounts, and these wires are passed through the pair of pipes. Furthermore, a pair of cloth boards are latched by a pair of pipe, and a solar cell module is fixed to a pair of cloth boards. That is, the solar cell module is located at a considerably high position from the ground and is present in the air.

  A space through which light can pass is made below the solar cell module, and even when solar power generation facilities are installed on farmland, sunshine is not significantly impaired. According to the inventor's estimation, if the distance between the photovoltaic power generation facilities and the number of solar cell modules installed between the pair of mounts are appropriately set, there is almost no influence on the yield, and the amount per one reaction. It can generate about 15KW.

  The solar cell module is located at a considerably high position from the ground, and machinery used for farm work such as a cultivator can be run under the solar cell module without any trouble.

  In the solar power generation facility using the aerial wire according to the second invention, in addition to the first invention, the pair of mounts are configured by vertically stacking a plurality of building frames for scaffolding.

  With this configuration, it is possible to configure a gantry using a commercially available building frame for a framework scaffold that is easily available.

  In the solar power generation facility using the aerial wire according to the third invention, in addition to the first invention, the lower part of the pair of mounts is installed in the ground, a drain hole is opened inside, and a weight is placed on the base plate Connected to

  With this configuration, a proof stress acts on the gantry, but the water can move in the ground through the drainage hole, so that the gantry can be kept horizontal, and the stability of the gantry can be improved by the weight.

  In the solar power generation facility using the aerial wire according to the fourth aspect of the invention, in addition to the first aspect of the invention, in the center part of the base plate, a forward member facing the opposite base is extended, and on both sides of the base plate, A backward member facing the opposite side of the opposite gantry is extended, and a side weight is placed on the backward member.

  In this configuration, the forward member prevents the tipping and the side weight on the backward member acts as a counter against the tipping moment, so that the base plate acts as if it is a book stand in the ground and falls forward. The stability of the gantry can be further improved.

  In addition to the first invention, the solar power generation facility using the aerial wire according to the fifth invention is a chain block.

  With this configuration, it is possible to adjust the tension acting on the wire using a commercially available chain block that is easily available and inexpensive.

  In the solar power generation facility using the aerial wire according to the sixth invention, in addition to the first invention, the pair of mounts are raised from the ground by a predetermined deflection allowance, and the longitudinal center portions of the pair of pipes are the pair of mounts The solar cell module is provided with a water gradient that descends from the pair of mounts toward the support column by being supported by the support column at a height lower than the predetermined deflection allowance.

  With this configuration, a sufficient water gradient can be imparted to the solar cell module without further tilting the solar cell module. Therefore, even if the solar cell module gets wet with rain, the rain can be drained immediately, and the solar cell module can be easily maintained.

  In the solar power generation facility using the aerial wire according to the seventh invention, in addition to the first invention, the pair of mounts are arranged in a horizontal pit provided on the slope.

  With this configuration, a solar cell module can be installed and power can be generated on a sloped land with a configuration substantially similar to that on a flat ground. In other words, power can be generated not only on flat landforms such as fields, but also on sloping lands such as tea fields, pastures, or forests, and the scope of provision of this facility can be greatly expanded.

  The solar power generation facility using the aerial wire according to the eighth aspect of the invention is a pair of footings, underground beams, and counter plates that are arranged in combination at each of two positions separated by a predetermined distance in a certain direction in the ground. A pair of reinforcement frames fixed to face each of the foundation and the pair of foundations, the inner hypotenuse facing the other side of the pair of reinforcement frames and the outer hypotenuse facing the opposite side of the pair of reinforcement frames A pair of operations in which one end is terminated and the other end is connected to the tension adjuster in each of the pair of reinforcement frames A pair of moving pulleys rotatably mounted in the middle of the pair of operation wires, one end of which is connected to one of the pair of moving pulleys, and the other end of the pair of moving pulleys. A pair of wires connected to the other side of the car are laid in parallel between a pair of reinforcing frames, each of the pair of wires is passed through the pair of pipes, and a pair of cloth plate hooks are placed at predetermined positions of the pair of pipes. The solar cell module is fixed to a pair of cloth plates.

  With this configuration, the force for lifting the span over which the pair of wires are bridged between the pair of reinforcing frames can be strengthened, so that the wind resistance performance can be improved far more than that of the first invention.

  According to the present invention, it is possible to generate electricity while making rice and the like by farming while using a wire, in other words, “double-cropping rice and electricity generation” can be realized.

  More specifically, it is possible to secure a certain amount of power generation while minimizing the influence of the shadow caused by the solar cell module.

(Embodiment 1)
Next, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a perspective view showing a part of a photovoltaic power generation facility using airborne wires according to Embodiment 1 of the present invention. 2A is a front view of the gantry according to the first embodiment of the present invention, FIG. 2B is a plan view of the base plate according to the first embodiment of the present invention, and FIG. 3 is an embodiment of the present invention. It is a perspective view of the solar power generation facility by the air wire which concerns on the form 1. FIG.

  The fixed direction in this embodiment is the north-south direction. However, this is the most preferable direction, and even if a certain direction is set in a direction slightly deviated from the north-south direction, a substantially similar effect can be obtained. Is included.

  Now, as shown in FIG. 3, the pair of mounts 10 are separated by a certain distance in the north-south direction. According to the inventors' estimation, the maximum value of the fixed distance is about 20 m. For example, when installing the equipment at a distance of about 30 m, it is desirable that the number of the gantry 10 is not two, but three, and the distance between each gantry 10 is about 15 m.

  Each gantry 10 is configured as follows. First, the ground is dug to some extent, and the base plate 1 is horizontally installed as shown in FIG.

  As shown in FIG. 2B, the base plate 1 has a horizontally long rectangle, and four attachment portions 1b are formed at the four corners of the base plate 1 in accordance with the positions of the leg portions of the building frame for the commercial scaffolding. .

  Further, four engaging portions 1c are provided on the side portion of the attachment portion 1b in order to connect the terminal portions of the wires 3 and 4. Although not shown in the figure, the locking portion 1c is preferably provided with a circular hole in the center of the rectangular plate, and the rectangular side surface is welded to the upper surface of a predetermined portion of the base plate 1.

  The base plate 1 is provided with a pair of left and right drain holes 1a through which water can move in the vertical direction of the base plate 1 through the drain holes 1a.

  A base end portion of a forward plate 5 (a forward member) facing the gantry 10 is fixed to the central portion of the base plate 1. Further, the base end portions of the rearward channels 6 and 7 (rearward members) facing the opposite side of the opposite gantry 10 are fixed to both side portions of the base plate 1.

  A central weight 8 is stacked on the center portion of the base plate 1 behind the forward plate 5, and the side weights are stacked on the front ends of the left and right rear channels 6, 7. 9 is placed.

  The base plate 1, the front plate 5, and the left and right rear channels 6, 7 are integrated, and these members are shaped like the bottom of the book stand in plan view, as shown in FIG. Further, the center weight 8 and the left and right side weights 9 oppose a falling moment in a direction in which the pair of mounts 10 tend to fall toward the other mount 10 side, and the stability of the pair of mounts 10 is improved.

  As the base plate 1 and the weights 8 and 9, etc., a galvanized iron plate or the like is preferably used.

  If the depth of the base plate 1 is about 70 cm from the ground G, it will be a footing with sufficient strength. Incidentally, since the depth of the soil dug by the tiller (not shown) is considerably shallower than 70 cm, there is no problem even if the tiller is used while the base plate 1 is buried in the ground.

  If the platform above the base plate 1 is removed, it can be returned to a normal rice field, or the base plate 1 itself may be removed from the ground. In addition, the base 10 and other equipment can be moved to another place for each base plate 1 (or leaving only the base plate 1 in the ground).

  As shown in FIG. 2A, when the installation of the base plate 1 or the like is completed, the lower end portion of the raised leg 11a is connected to the mounting portion 1b, and the lower end portion of the lower building frame 11 is connected to the upper end portion of the raised leg 11a. Further, the lower end of the upper building frame 12 is connected to the upper side of the lower building frame 11. Such a way of assembling may be the same as the procedure for assembling a scaffold at the temporary site.

  The effective height of the raising leg 11a is the deflection of the central portion of the outer wire 4 and the pipe 21 (for example, about 80 cm), and the combined height of the lower building frame 11 and the upper building frame 12 is, for example, about 3.4 m. good.

  That is, it is preferable to reinforce the lower building frame 11 and the upper building frame 12 by inserting a brace 28 or to bridge and reinforce the cloth boards 13 and 14 between the lower building frame 11 and the upper building frame 12. .

  In the first embodiment, it is assumed that solar power generation facilities are installed on farmland, particularly rice fields. And even if the outer wire 4 and the pipe 21 are low (in the central part), the solar cell module 23 is installed at a level about 3 m higher than the level of the ground G of the rice field, in other words, in the air. As will be described later, the photovoltaic power generation facilities can be spaced apart from each other in plan view, but in addition to this, a height difference of about 3 m is provided so that light can enter the ground obliquely. is there.

  Therefore, the gantry 10 has a three-stage configuration including a raised leg 11a, a lower building frame 11, and an upper building frame 12 from the bottom. However, if necessary, the level of the top surface of the gantry 10 can be changed. The raising may be performed above the upper building frame 12.

  As shown to Fig.2 (a), the 1st wire guide 15 and the 2nd wire guide 16 are each provided in the edge | side which faces a north-south direction among the edge | sides of the upper surface of the mount frame 10. FIG.

  The first wire guide 15 and the second wire guide 16 are preferably provided with a roller 17 around which the wires 3 and 4 circulate, a wire presser 18 that restricts the wires 3 and 4 from jumping, and the like.

  As shown in FIG. 1, the outer wire 4 is stretched from the engaging portion 1 c located on the outer side in the north-south direction of the pair of mounts 10, while being guided by the first wire guide 15 and the second wire guide 16. The wire 4 is extended to the other gantry 10 side, and the outer wire 4 is terminated at a locking portion 1c located on the outer side of the other gantry 10 in the north-south direction.

  On the outside in the north-south direction of the gantry 10, a hook 19 and a chain block 20 (an example of a tension adjuster) are interposed in the outer wire 4. By operating the chain block 20, it is possible to apply tension to the outer wire 4 to reduce the tight tension, or to weaken the tension and deflect the outer wire 4.

  Incidentally, if 10 solar cell modules 23 (about 150 kg per sheet) are supported on the outer wire 4, the tension when strongly tensioned may be about 1.5 t to 2 t. Such a tension can be easily obtained using a commercially available chain block.

  On the other hand, the inner wire 3 is stretched on the inner side of the gantry 10 in the north-south direction in order to balance the outer wire 4.

  As shown in FIGS. 1 and 3, in the present invention, the solar cell module 23 is not directly fixed to the outer wire 4. That is, the outer wire 4 is passed through the inner cavity of the pipe 21. A water pipe can be suitably used as the pipe 21.

  In general, it is rare that a single water pipe is sufficient, and although not shown, a threaded portion is formed at the end of the water pipe, and it is used while being added in the axial direction using a joint such as a socket. At this time, a seal tape may or may not be wound around the thread portion.

  In this way, as shown in FIG. 3, a pair of left and right pipes 21 (facing the north-south direction) is created between the gantry 10 at a height of about 3 m in the air. In addition, the outer wire 4 passes through each pipe 21.

  As shown in FIG. 3, the aerial member composed of the outer wire 4, the pipe 21, the solar cell module 23, and the like bends downward so as to be lowest at the center due to its own weight. It is desirable that a support column P having a height that takes into account the deflection allowance is set at the center portion, and the center portion of the aerial member is supported by the support column P.

  For example, if the span between the gantry 10 and 10 is 20 m, the deflection allowance is 80 cm, and the combined height of the upper building frame and the lower building frame 12 and 11 is 3 m, each solar cell module 23 is not further inclined. In addition, a sufficient water gradient can be given to each solar cell module 23, and drainage and maintenance can be easily performed.

  As shown in FIG. 1, the hooks 22 a of the pair of cloth plates 22 are locked to the pair of pipes 21, and the solar cell module 23 is fixed to these cloth boards 22. By doing in this way, the solar cell module 23 in a state where a water gradient is applied at a position about 3 m higher than the ground G is supported, and power generation by the module 23 becomes possible.

  In addition, as shown in FIG. 3, in a state where the solar cell module 23 is supported at a high position, farming is possible as long as sufficient sunshine is obtained below the solar cell module 23. That is, the crop 24 can be grown at the level of the ground G. Rice is a representative example of the crop 24, but crops other than rice may be grown.

  Next, a more specific installation procedure will be described with reference to FIG. 4 (a), FIG. 4 (c), FIG. 4 (e), and FIG. 4 (g) are plan views showing the installation procedure of the solar power generation facility using the air wire according to Embodiment 1 of the present invention, 4 (b), 4 (d), 4 (f), and 4 (h) are side views showing the installation procedure.

  First, as shown in FIGS. 4 (a) and 4 (b), the gantry 10 is lifted and the tension of the outer wire 4 is lowered, and the outer wire 4 is passed through the pipe 21. At this time, it is desirable to place the standing horse 25 on the ground G with a predetermined interval and to support the pipe 21 and the outer wire 4. The height of the standing horse 25 is preferably about 1 m to 2 m, for example.

  Next, with the support by the standing horse 25, as shown in FIG. 4C and FIG. Furthermore, one solar cell module 23 is fixed to the pair of cloth plates 22.

  When the above preparation is completed, the chain block 20 provided on the gantry 10 is operated to increase the tension of the outer wire 4. As a result, as shown in FIGS. 4E and 4F, the aerial member supported by the outer wire 4 rises. At the center between the gantry 10 and 10, the support P is set up to support the aerial member.

  Furthermore, in order to prepare for a strong wind such as a typhoon, as shown in FIG. 4 (h), a brace 26 is slanted at the center of the gantry 10 and the pipe 21 to increase the overall strength in order to cope with the wind tilt. And good.

  In addition, in the state of FIG.4 (f), agricultural work, such as agitation of a soil by a tillage machine and rice planting, can be performed. Furthermore, in the state of FIG. 4 (h), even if the crop 24 grows and extends, power generation by the solar cell module 23 is possible regardless of that.

  Next, the layout procedure of the solar cell module according to the season will be described with reference to FIGS.

  FIG. 5 is a year-round layout diagram of the solar cell module according to Embodiment 1 of the present invention, FIG. 6 is a plan view showing an additional procedure of the solar cell module according to Embodiment 1 of the present invention, and FIG. 4 is a winter layout diagram of the solar cell module according to Embodiment 1. FIG.

  In the first embodiment, it is assumed that the yield of rice fields is reduced by 10% or less with respect to rice, and the power generation is about 15 kw per reaction.

  In such a case, what is necessary is just to arrange | position the solar cell module 23 with a layout as shown in FIG. In this case, the number of solar cell modules 23 is 60, and the distance in the east-west direction between each row (which corresponds to the pair of mounts 10) can be considerably widened. Installed with the same north-south spacing.

  The layout of the solar cell module 23 may be determined in consideration so that a shadow does not occur directly below (that is, the portion where the crop 24 grows).

  On the other hand, rice is not planted in the rice field until approximately November to March of the following year. If it is such time, as shown in FIG. 6, FIG. 7, it is good to insert the additional solar cell module 27 between the solar cell modules 23, and to increase electric power generation.

  To insert, work is performed in reverse order to FIGS. 4 (h) to 4 (c), and when insertion is completed, the work of FIGS. 4 (c) to 4 (h) is performed again. In addition, when performing maintenance, such as washing | cleaning of the solar cell module 23, it can respond easily by the operation | work of reverse order to FIG.4 (h)-FIG.4 (c).

  FIG. 8 is a plan view showing the shadows of the spring equinox days and the autumn equinox days in Embodiment 1 of the present invention, and FIG. 9 is a plan view showing the shadows of the summer solstice days in Embodiment 1 of the present invention. is there. Both are based on the latitude around Fukuoka City.

  8 and 9, curve A is a boundary line of an area that is shaded for 4 hours per day, and curves B, C, and D are areas that are shaded for 3 hours, 2 hours, or 1 hour each day. Is the boundary line.

  As shown in FIG. 9, the shadow area is the narrowest on the summer solstice, and on the spring equinox day and the autumn equinox day, as shown in FIG.

  Assume that the height of the solar cell module 23 is 3 m, and the intervals between the columns shown in FIG. Specifically, 80 cm is a standard for a height of 3 m.

  Of course, each numerical value described above is merely an example, and in practice, various numerical values can be changed as necessary, and even when such a change is accompanied, it is included in the protection scope of the present invention.

(Embodiment 2)
Next, Embodiment 2 of the present invention will be described with reference to FIGS. In order to avoid redundant explanation, only the differences are mentioned. That is, items not mentioned are the same as in the first embodiment.

  FIG. 10 is a side view showing a photovoltaic power generation facility using an aerial wire according to Embodiment 2 of the present invention, and FIG. 11 is a perspective view showing the facility.

  In Embodiment 1, power generation equipment is installed in a rice field that is flat. However, if the following device is added, solar power can be generated in the same manner as in the first embodiment even on an inclined land.

  As shown in FIG. 10, the most different point from the first embodiment is that the gantry 10 is not installed in parallel with the inclined land 40, but first, a pit 30 having a plurality of horizontal ground contact surfaces H in the middle of the inclined land 40. Is provided.

  In order to prevent soil from flowing into the pit 30, an L-shaped retaining wall 31 that receives the earth pressure of the inclined land 40 is installed on the side of the pit 30. It is better to use earth pressure for the reaction force of the wire.

  Furthermore, in order to cope with the inclined ground 40, it is desirable to extend the keel 32 below the base plate 1 and firmly fix the gantry 10 to the ground. In addition, in the example of FIG. 10, although the mount frame 10 was comprised only with the 1-step building frame, it cannot be overemphasized that 2 steps | paragraphs or more may be provided. Furthermore, a wire retainer 33 whose lower end is terminated at the L-shaped retaining wall 31 is provided, and the upper end of the wire retainer 33 is preferably connected to the upper end of the gantry 10.

  The wire 4, the pipe 21 and the like can be configured in the same manner as in the first embodiment, except that the wire 4, the pipe 21, and the solar cell module 23 supported by them are installed obliquely along the inclined land 40.

  When it is not necessary to consider the sunshine on the crop such as the rough terrain 40, the solar cell modules 23 may be packed and arranged at a high density as shown in FIG.

  As shown in FIG. 11, even if the inclined land 41 is not flat and has unevenness, if the support of the solar cell module 23 by the wire 4 is not hindered, the aerial wire of the second embodiment is used as in FIG. 10. Install solar power generation equipment and generate electricity.

  The other points are the same as in the first embodiment.

(Embodiment 3)
Next, Embodiment 3 of the present invention will be described with reference to FIGS. In addition, in order to avoid duplication description, while attaching the same code | symbol to the same element, only a difference is mentioned. That is, items not mentioned are the same as in the first embodiment.

  12 is a perspective view showing a photovoltaic power generation facility using an airborne wire according to Embodiment 3 of the present invention, FIG. 13 is a side view of a reinforcing frame according to Embodiment 3 of the present invention, and FIG. 14 is Embodiment 3 of the present invention. FIG. 15 is a perspective view showing an additional point of the power generation module according to Embodiment 3 of the present invention.

  In the first embodiment, the outer wire 4 is bridged between the pair of mounts 10, the load of the solar cell module 23 and the like acting on the outer wires 4 is transmitted from the outer wire 4 to the mount 10, and finally via the base plate 1. And shed into the ground. However, in this case, the force for lifting the span over which the pair of outer wires 4 are bridged between the pair of mounts 10 becomes insufficient, and wind resistance may be insufficient.

  In the third embodiment, a solar power generation facility with improved wind resistance performance is obtained by adopting the structure described below as compared with the first embodiment.

  First, in Embodiment 3, the load is not transmitted to the gantry 10 only by the outer wire 4, but the outer wire 4 is terminated in front of the gantry 10.

  Then, as shown in FIG. 13, one end of an operation wire 67 different from the outer wire 4 is connected to a winch 66 as a tension adjuster, and the operation wire 67 is folded back upward, horizontally, and V-shaped. Thus, the other end is terminated. Among these, the vicinity of the apex that is folded back in a V shape is caused to circulate around the moving pulley 68, and the end of the outer wire 4 is connected to the moving pulley 68.

  Next, the detail of each element of the photovoltaic power generation facility of Embodiment 3 is demonstrated.

<Basic>
As shown in FIGS. 12 to 14, the foundation 50 is installed at each of two positions separated by a predetermined distance in the north-south direction.

  The foundation 50 is disposed by combining footings 51 and 52, underground beams 53 and 54, and counter plates 55 and 56. More specifically, a pair of iron plate plates formed in a rectangle so that the north-south direction is the longitudinal direction are arranged horizontally and spaced in parallel to form footings 51 and 52. The width of the footings 51 and 52 is desirably about 600 mm.

  On the upper surface of each footing 51, 52, an underground beam of substantially equal length to the footings 51, 52 is fixed by welding or the like with an underground beam made of H-shaped steel. As a result, the foundation 50 is shaped like a ski plate, and the ground strength can be substantially improved to counteract the reaction force from the ground.

  Then, the end portions of the counter plates 55 and 56 are fixed inside the both end portions of the footing 51. As in the first embodiment, the counter plates 55 and 56 are provided with drain holes 55a and 56a, respectively.

  When the foundation 50 is installed in the ground, the weight of the soil on the counter plates 55 and 56 acts, and the load to counter the tensile force of the wires 4 and 67 described later increases. In addition, it is desirable that the counter plate 56 on the front side has a large area as much as possible to enhance the stability in accordance with the earth bearing strength of about 2 to 3 tons. It is also desirable to drive the piles into the drain holes 55a and 56a to stop the slip.

In the third embodiment, a pair of mounts 10 are provided on the foundation 50 as in the first embodiment. However, as described above, the gantry 10 of the third embodiment functions as a guide for guiding the outer wire 4 rather than a member that receives a load such as the solar cell module 23. Although not shown, pulleys or rollers for changing the direction of the operation wire 67 are provided at two corners (see FIG. 13) at the top of the gantry 10.

  The third embodiment is the same as the first embodiment in that the outer wire 4 is inserted into the pipe 21 ', but an enlarged flange 21'a is formed at the end of the pipe 21'. The difference is that the flanges 21'a are butted together and the pipes 21 'are connected in the longitudinal direction. The connection by the flange 21'a is to prevent the outer wire 4 from being bent and damaged in a V shape. The flange 21'a may be formed of a metal material or a resin material.

  An end hook 4a is attached to the end of the outer wire 4, and the end of the outer wire 4 is terminated by the end hook 4a. The end hook 4a is locked to the top of the moving pulley 68, so that the end of the outer wire 4 is connected to the moving pulley.

  On the foundation 50 described above, a pair of reinforcing frames 60, 60 'is erected. Since the reinforcing frames 60 and 60 'have the same configuration, only the reinforcing frame 60 will be described below.

  The reinforcing frame 60 is substantially A-shaped in a side view, and is fixed so as to face each other of the pair of foundations 50. The reinforcing frame 60 has an inner hypotenuse 62 that tilts backward toward the other side of the pair of reinforcing frames, and an outer hypotenuse 61 that tilts forward facing the opposite side of the pair of reinforcing frames.

  The lower end 61a of the outer hypotenuse 61 and the lower end 62a of the inner hypotenuse 62 are each fixed to the underground beam 53, but each fixing location is shifted in the north-south direction. The upper end 61 b of the outer hypotenuse 61 and the upper end 62 b of the inner hypotenuse 62 are fixed to each other in the vicinity of the apex of the reinforcing frame 60.

  In the middle of the reinforcing frame 60 in the height direction, an upper lateral side 63 and a lower lateral side 64 are arranged in two upper and lower stages, and both end portions of these lateral sides 63 and 64 are respectively an outer oblique side 61 and an inner oblique side 62. The reinforcing frame 60 is reinforced by being fixed inside. In particular, the provision of these lateral sides 63 and 64 can improve the resistance to buckling as a whole of the reinforcing frame 60. In addition, the number of horizontal sides 63 and 64 and an installation location can be variously changed as needed. Further, the end of the upper lateral side 63 on the inner oblique side 62 side has an action of stopping buckling.

  A horizontal platform 65 is attached to the lower lateral side 64, and a winch 66 as a tension adjuster is installed on the platform 65. As in the first embodiment, a manual drum or a manual chain block can be used as the tension adjuster in addition to the winch.

  On the other hand, a locking portion 69 is provided near the top of the inner hypotenuse 62. The operation wire 67 drawn out from the winch 66 is once pulled upward, and then guided horizontally and toward the other gantry 10 by the horizontal second wire guide 16 (member on the gantry 10).

  When the operation wire 67 is separated from the second wire guide 16, the operation wire 67 is bent into a V shape, and is terminated when the hook 70 provided at the end of the operation wire 67 is engaged with the engagement portion 69.

  As described above, the portion of the operation wire 67 that bends in a V shape circulates around the moving pulley 68, and the end hook 4 a provided at the end of the outer wire 4 is connected to the moving pulley 68. The

  Here, when the winch 66 is driven, the operation wire 67 is maintained in a slack state, and the operation wire 67 is pulled out for a long time, the pipe 21 ′ and the solar cell module 23 are passed on the ground as shown in the lowermost stage of FIG. 13. As the height (maintenance height), maintenance such as cleaning and replacement of defective parts can be performed.

  If the length of the operation wire 67 pulled out is slightly shorter than the case of the maintenance height, as shown in the middle stage of FIG. 13, the pipe 21 ′ and the solar cell module 23 are not hindered from farming (more specifically, Power generation by the solar cell module 23 can be performed at an appropriate height (power generation height) that reduces the shade of the ground crops. During power generation, a fixed wire 71 may be stretched between the movable pulley 68 and the bottom of the reinforcing frame 60 to improve the stability of the equipment.

  When the length of the operation wire 67 drawn out is further shortened than in the case of the power generation height, the pipe 21 ′ and the solar cell module 23 are at a height close to the top of the reinforcing frame 60 (agricultural work) as shown in the upper part of FIG. As the height), for example, the farming work can be performed such that the tiller passes below the solar cell module 23 and the pipe 21 ′ without being disturbed by the solar cell module 23 and the pipe 21 ′.

  As apparent from FIG. 13, the load from the solar cell module 23 and the like is transmitted from the outer wire 4 to the movable pulley 68, is transmitted to the reinforcing frame 60 through the operation wire 67, and flows into the ground through the foundation 50. .

  At this time, as shown in FIG. 13, a moment in the direction of turning up as shown by the arrow N1 acts on the rear side of the reinforcing frame 60 (ie, the outer hypotenuse 61), and the front of the reinforcing frame 60 (ie, the inner hypotenuse side). 62), a moment in the direction of being pushed down into the ground acts as shown by the arrow N2. That is, the load acting on the entire reinforcing frame 60 is distributed and transmitted to the inner hypotenuse 62 and the outer hypotenuse 61.

  Here, when the weight of the soil located above and below the foundation 50 is applied to the foundation 50, the wind resistance performance of the reinforcing frame 60 is further improved. According to the inventor's trial calculation, it is possible to withstand strong winds with a wind speed of about 60 meters. More specifically, a tensile force acts on the outer hypotenuse 61 of the reinforcing frame 60, and as a result, a moment in the direction of lifting in the direction of arrow N1 in FIG. 13 acts on the foundation. In this embodiment, the area of the counter plate 55 is increased, more soil is placed on the counter plate 55, and the weight of the soil is applied to the counter plate 55. This counters the moment.

  As described above, since the wind resistance performance is improved, as shown in FIG. 15, the substantial number of installed solar cell modules 23 can be increased.

  That is, the photovoltaic power generation facilities A and B according to the third embodiment are installed in parallel at some interval, and the relay wires 80 and 81 are stretched at this interval, and the additional solar cell module 82 is connected to the relay wires 80 and 81 may be supported. Scaffolding nails may be attached to the ends of the relay wires 80 and 81.

  The relay wires 81 and 81 may be provided in the photovoltaic power generation facilities A and B themselves, or may be added separately. In this way, it is possible to significantly increase the number of solar cell modules per installation area and improve power generation efficiency while opening a gap between the solar cell modules to ensure a wind passage during strong winds. Instead of the relay wires 80 and 81, square pipes may be assembled in a ladder shape and bridged between the photovoltaic power generation facilities A and B. As a distance between the photovoltaic power generation facilities A and B, for example, about 4200 mm is appropriate.

  The other points are the same as in the first embodiment.
