JP6345449B2 - Solar power generation facility for relocation between Tabata - Google Patents

Description

  The present invention relates to a photovoltaic power generation facility for relocation between fields, which can provide structural strength performance exceeding the standard defined by the Building Standard Law after installation, and further does not hinder farming as much as possible during the farming season. 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.

  There is a debate that it is irresponsible to make a claim that there is no alternative energy and that nuclear power is zero immediately.

  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.

  By the way, according to the estimation of the present inventor, if solar power generation in farmland such as paddy fields and abandoned farmland is put on track in Japan, it is possible to produce about 30% of the total annual power generation. 30% of the total annual power generation is comparable to that of Japan's 54 nuclear power plants, and solar power generation can replace nuclear power generation. In order to generate 30% of the total annual power generation by solar power generation, it is calculated that 30% of the paddy field area currently used for rice cultivation and 46% of the abandoned farmland area are used. In this calculation, the operation period of photovoltaic power generation is assumed to be 6 months for paddy fields other than the rice cultivation period, and the abandoned farmland is assumed to be full year. The power generation in paddy fields is equivalent to 20% of the total annual power generation, and the power generation in abandoned farmland is equivalent to 10% of the total annual power generation. It is assumed that more than 1 million healthy elderly people and 750,000 households, half of the farmers, are assumed to be responsible for operating solar power generation facilities in farmland. If these assumptions are satisfied, it will be possible to satisfy Japan's power generation using only solar energy without using nuclear power generation.

  However, the term “agricultural land” here does not mean that the agricultural land is converted to land for power generation. Rather, it refers to farmland that is not actually farming. Point to.

  Therefore, in the farmland referred to in this specification, when it is not a fallow land, farming is performed as usual during the farming period, and power generation is performed during other periods.

  Such a utilization method can be said to be a method that can be expressed as “double cropping of rice and power generation” if the farmland is a rice field.

  If the farmland is used / utilized in this way, there is no need to perform troublesome procedures such as diversion of farmland. However, most parts of the photovoltaic power generation facility for moving between fields must be removed at the time of original farming, and large transport machines cannot be used around the farmland. The scaffolding is bad. That is, a simple mechanism that meets such circumstances is required.

  More specifically, the required photovoltaic power generation facility for relocation between fields must satisfy all of the following conditions.

  Condition (1): Since it is assumed that it can be moved from one farmland to another, it can be easily dismantled, moved and assembled at another site.

  Condition (2): Since the site may be placed under severe weather conditions such as typhoons at the time of installation, structural strength performance exceeding the standards stipulated by the Building Standards Act should be obtained. It would be more desirable if the facilities could be dismantled and easily returned to the farmland, and the dismantled facilities (with permission) could be accumulated on a part of the farmland.

  Condition (3): Considering that the power purchase rate is specified, the installation or manufacturing cost can be made as low as possible.

  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.

Patent Document 2 (Japanese Patent Laid-Open No. 10-125945) connects adjacent solar cell arrays in a foldable manner, and slidably engages the side bottoms of the solar cell arrays with a pair of guide rails, A technique for folding and storing arrays in a strong wind or the like is disclosed.

  However, in both Patent Documents 1 and 2, it is not assumed at all that the solar cell panel once installed is removed from the wire, or further transferred to another site. Absent.

  When the conventional technology is used for farmland, when the farmland enters the farming period, the solar panel remains on the site, which significantly disturbs the farm work. In other words, according to the conventional technology, “double-cropping of rice and power generation” cannot be performed.

  Therefore, the present invention provides a photovoltaic power generation facility for moving between fields, which can obtain structural strength performance exceeding the standard defined by the Building Standard Law after installation while using a wire, and further prevents farming as much as possible during the farming season. With the goal.

  The photovoltaic power generation facility for moving between fields according to the first aspect of the present invention is a transfer between fields where a pair of foundations are installed in the ground of the fields and a pair of support members are installed on the pair of foundations so as to face each other. Each of the pair of support members is a support column standing on a pair of foundations, and a right arm and a left arm that can be extended vertically and horizontally with respect to a base end portion of the support column. The central wire is detachably stretched between the base end portions of the support column, and the first side wire and the second side wire are parallel to the central wire between the distal end portion of the right arm and the distal end portion of the left arm. Two side wires are detachably stretched, a solar cell panel, a frame body that holds the solar cell panel, and a pair that is provided on the frame body and holds the solar cell panel in a posture inclined with respect to the ground. A panel module having a first folding frame. Detachably connected to at least one of the first wire set consisting of the central wire and the second wire set consisting of the central wire and the second side wire, and by the longitudinal tension of the one connected wire set The panel module is provided with a supporting force that opposes the external force.

  In this configuration, in a state before installation, a pair of foundations are installed in the field of the fields, but the foundations do not appear on the ground surface and do not hinder farming. Further, a support column is erected on the foundation, and a right arm and a left arm are positioned on the left and right sides of the base end portion of the support column. That is, most of the area of the field is open except for the place where the support, the right arm and the left arm are located, and the farmer can farm using this area.

  When installing, the base ends of the pair of struts, one right arm tip and the other left arm tip, and one left arm tip and the other right arm tip face each other. And in a parallel positional relationship.

  Then, a central wire is provided between the base ends of the pair of support columns, a first side wire is provided between one right arm tip and the other left arm tip, and one left arm tip and the other right arm tip. A second side wire is detachably stretched between the two parts, but these wires are parallel to each other. Thereby, the 1st wire set which consists of a 1st side wire and a center wire, and the 2nd wire set which consists of a center wire and a 2nd side wire are formed.

  Then, the panel module is carried near these wires, a pair of folding frames are opened, and the solar cell panel is inclined to the ground. At least one of the first wire set and the second wire set is attached to the panel module. Installation is completed when these are connected. If the panel module is connected to the wire stretched in this way, sufficient structural strength performance can be obtained as the entire power generation facility.

  On the other hand, when removing, the connection between the panel module and the wire set is released, and the pair of folding frames are folded. Further, the wires are loosened and removed, and the wires and the panel module are removed. This frees most of the field and allows farmers to start farming.

  In the photovoltaic power generation facility for moving between fields according to the second invention, in addition to the first invention, in a posture in which the pair of folding frames are erected, the pair of folding frames positioned on the back side of the solar cell panel A wire locking part is provided at the rear side, and in the pair of folding frames, the front wire with the locking tool attached to the tip is pulled out from the front side opposite to the rear side, and either the first or second wire set , The wire locking portion is locked to one wire, and the locking tool is detachably connected to the other wire, and in the direction intersecting the longitudinal tension of one wire set by the tension of the front wire. Give support.

  With this configuration, the panel module can be connected to the wire easily and reliably using a member already provided on the folding frame, that is, without using a special connecting jig.

  In the photovoltaic power generation facility for relocation between fields according to the third invention, in addition to the first invention, a pair of leg plates having a receiving groove formed at the center in the longitudinal direction is prepared, and a pair of folding frames are erected in a posture. The side of the folding frame facing the ground is inserted into the receiving groove of the leg plate, and the leg plate is laid on the ground.

  With this configuration, a load such as the weight of the solar cell panel is concentrated on the side facing the ground, but this load can be transmitted to the ground via a leg plate having a larger area. As a result, a situation where the panel module sinks into the ground can be suppressed.

  In the photovoltaic power generation facility for moving between fields according to the fourth invention, in addition to the first invention, a hinge part is provided at the base end part of the support column, and the base end parts of the right arm and the left arm are respectively attached to the hinge part. As a result, the folding position that is parallel to the column and the unfolded position that is orthogonal to the column can be taken.

  With this configuration, during the farming period, the right arm and the left arm can be folded to be parallel to the column, the vertical projection area of the right arm and the left arm can be reduced, and a larger area can be provided to farming. Can do. On the other hand, when performing power generation, the right arm and the left arm are set at a deployment position orthogonal to the column, and a sufficient distance is secured from the base end of the column to the tip of the right arm and the tip of the left arm. The widths of the first wire set and the second wire set can be set appropriately.

  According to the present invention, all of the above conditions (1) to (3) can be satisfied, and “double-cropping of rice and power generation” can be realized.

  Also, during the farming season, the main part of the power generation facility is removed from the fields, and most of the fields can be opened for farming.

(Embodiment 1)
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a bottom view of the panel module according to Embodiment 1 of the present invention. 2A is a rear view of the module in a state in which the folding frame is opened, FIG. 2B is an explanatory view of the leg plate, and FIG. 3 is a side view of the module.

  As will be described in detail later, this panel module A is designed so that it can be disassembled for easy transportation, installation and removal. The solar cell panel 1, the frame body 2 and the folding frames 3, 5 are The main material.

  As shown in FIG. 1, a frame 2 is fixed to the peripheral portion of the back surface of the solar cell panel 1 (the surface opposite to the surface that receives sunlight).

  The folding frames 3 and 5 are all accommodated in the frame 2 in the thickness direction of the frame 2 at the folding position as shown in FIG. Of course, also in this folding position, the folding frames 3 and 5 are within the vertical projection area of the frame 2 (at the same time, the solar cell panel 1). Therefore, for example, it is not bulky to stack a plurality of panel modules A (solar cell panel 1, frame body 2 and folding frames 3, 5 etc.) on a light truck bed in the thickness direction, and folding frames 3, 5 Does not damage the solar cell panel 1.

  As shown in FIG. 1, folding frames 3 and 5 are arranged symmetrically on the frame 2 with the longitudinal center line of the frame 2 as the axis of symmetry, and both ends of the folding frames 3 and 5 are The frame 2 is connected by a hinge 2a.

  In the state shown in FIG. 1, the folding frames 3 and 5 are in a folded state, but when the hinge 2 a is operated, the folding frame 3 is moved from the state of FIG. 1 as shown in FIG. 5 can be raised, and the posture orthogonal to the frame 2 can be taken.

  Since the folding frames 3 and 5 are symmetrical, only the folding frame 3 will be described in detail.

  Each part of the foldable frame 3 is preferably configured by bending a reinforced steel bar having a diameter of about 6 millimeters as a main material.

  If it does in this way, while being lightweight and easy to carry by hand, it can hold | maintain sufficient intensity | strength.

  The outer shape of the folding frame 3 is a right triangle in which the base 31 is the longest side and the short side 33 and the long side 34 are orthogonal to each other.

  In this right triangle, an angle θ formed by the base 31 and the long side 34 is an inclination angle formed by the solar cell panel 1 with respect to the ground G (see FIG. 3).

  It is desirable to set the angle θ in consideration of the latitude of the installation location.

  However, the tip portions of the base 31 and the long side 34 are cut off in the vicinity of the hinge 2a, and more precisely, the folding frame 3 has a trapezoidal shape having a base 31, a short side 33, a long side 34, and a front side 35. It has become.

  By doing so, even if the folding frame 3 is folded as shown in FIG. 1, or the folding frame 3 is perpendicular to the ground as shown in FIG. Even so, the folding frame 3 is always within the projected area of the solar cell panel 1.

  In other words, the folding frame 3 does not protrude before and after the solar cell panel 1, and the space factor when arranging a plurality of solar cell panels 1 close to each other in the front and rear becomes good. Further, when the folding frames 3 and 5 are folded, they are accommodated in the thickness direction of the frame body 2, and a good space factor is maintained even when the panel modules A are stacked.

  Next, the internal structure of the folding frame 3 will be described.

  First, an inner long side 36 substantially parallel to the base 34 is provided inside the base 34, and both end portions of the inner long side 36 are bent so as to be parallel to the base 31 and the short side 33, respectively. At the base 31 and the short side 33.

  A portion closer to the base 31 than the inner long side 36 is a reinforcing portion, and a reinforcing material 42 is disposed at a corner between the base 31 and the short side 33, and a reinforcing material 41 is provided at the other portion. Be placed.

  Reinforcing rings 37 and 38 bent in a square shape are fitted on both sides between the inner long side 36 and the long side 34.

  A portion of the reinforcing member 41 parallel to the reinforcing rings 37 and 38 is a parallel portion 41 a welded to the opposite side of the reinforcing rings 37 and 38 on the inner long side 36.

  As shown in FIG. 2A, a locking portion 6 a for locking the brace 6 is provided in the vicinity of the reinforcing material 42 on the bottom 31. Similarly, the folding frame 5 is provided with a locking portion 7 a for locking the wand 7.

  As shown in FIG. 1, a pair of hinges 2b and 2b are fixed to the center side of the frame 2 with respect to the hinges 2a on both sides. The base end is pivotally supported so that it can swing.

  That is, as shown in FIGS. 2 (a) and 3, the folding frames 3 and 5 are erected vertically from the state of FIG. 1 with respect to the frame 2 and the canes 6 and 7 are also raised to engage the locking portion 6a. , 7a, the folding frames 3 and 5 can be kept standing upright with respect to the frame body 2 when the tips of the canes 6 and 7 are attached.

  As shown in FIG. 1, in the vicinity of the inner long side 36 of the short side 33, a wire locking portion 43 having a notch 43 a parallel to the axial direction of the short side 33 is provided. Although not shown, it is desirable that the vertical position of the wire locking portion 43 can be adjusted using, for example, a long hole or the like in accordance with the unevenness of the ground G.

  When the folding frames 3 and 5 are raised as shown in FIGS. 2A and 3, the wire locking portion 43 is positioned at a level that is a short distance higher than the ground, and at the rear side of the folding frames 3 and 5. It can be detachably connected to the rear wire 48 (any one of the first side wire 70, the center wire 71, and the second side wire 72, see FIG. 7).

  On the other hand, on the front side (front side 35 side) of the panel module A, the proximal end portion of the front wire 44 having a locking tool (for example, a carabiner) 45 attached to the distal end portion is fixed. A turnbuckle 69 is attached in the middle of the front wire 44.

  Therefore, as shown in FIG. 3, the front wire 44 is pulled forward, the locking tool 45 is locked to the front wire (which is paired with the rear wire 48), and the turnbuckle 69 is operated to operate the front wire. When tension is applied to 44, the module A can be fixed to the wires before and after the panel module A.

  If the folding frames 3 and 5 are raised and grounded as they are, the long side 34 may bite into the ground and the panel module A may sink. For this reason, as shown in FIG. 1, two leg plates 46 are detachably attached to the lower side of the central portion of the frame 2. The leg plates 46 are formed with receiving grooves 47 along the longitudinal center line thereof.

  Needless to say, the bottom area of the leg plate 46 is much larger than the installation area of the long side 34. Therefore, even if the weight of the entire panel module A acts on the long side 34, as shown in FIG. 2B, the long side 34 is put in the receiving groove 47 and grounded via the leg plate 46, Problems such as the settlement described above can be prevented. The panel module A has an appearance as shown in FIGS. 12 (a) and 12 (b).

  Next, the wire tension applying mechanism of this embodiment will be described with reference to FIGS. 4 (a) and 4 (b).

  Here, in the present invention, the pair of support columns 50 are erected on the ground G with a predetermined distance apart from each other.

  Each column 50 may be either a columnar shape or a prismatic shape, but is formed in a cylindrical shape having a hollow inside. In the support column 50, three guide grooves 54 are vertically opened by a predetermined length by being shifted by 90 degrees from the upper end portion thereof.

  A hydraulic jack 51 is housed in the lower side of the support column 50, and a hose terminal 55 of the hydraulic jack 51 is directed laterally outward from the support column 50 through a hole (not shown) formed in a side surface of the support column 50. Protruding.

  A head portion 52 is fixed to the distal end portion of the rod 51a of the hydraulic jack 51, and wire locking pieces projecting to the outside of the column 50 through the three guide grooves 54 described above on the side surfaces of the head portion 52, respectively. The base end portion of 53 is fixed.

  In this embodiment, as shown in FIG. 7, all of the first side wire 70, the center wire 71, and the second side wire 72 are guided to the proximal end portion of the support column 50 and provided at the proximal end portion. By turning around the pulley 65 and changing the direction upward, the pulley 65 is locked by these wire locking pieces 53 to be terminated.

  In short, the ends of the wires 70 to 72 are all arranged from the bottom to the top on the side of the column 50.

  As shown in FIG. 4A, in a state where no oil is press-fitted from the hose terminal 55, the rod 51a is almost housed in the hydraulic jack 51, and the head portion 52 (that is, the three wire locking pieces 53) is , In a relatively low position. As a result, the wires 70 to 72 terminated by the wire locking piece 53 are loosened, and the tension of these wires 70 to 72 is almost zero. On the other hand, when attaching the panel, it is better to stretch the wire slightly and straighten the wire. In this way, the side space without wires can be used as a street through which people and machines can pass.

  In this state, the wires 70 to 72 are soft and easy to operate. That is, the operation | work which connects / disconnects the wire locking part 43 and the locking tool 45 which were mentioned above to each wire 70-72 is easy.

  After such work is completed, oil is pressed into the hose terminal 55, and the rod 51a is protruded upward as shown in FIG. 4 (b). If it carries out like this, the head part 52 and the three wire locking pieces 53 will move upward, and the edge part of each wire 70-72 will be pulled up.

  As a result, an appropriate tension can be applied to each of the wires 70 to 72, and the panel module A connected through the wire locking portion 43 and the locking tool 43 is immovable by the tightened wires 70 to 72. Will be supported.

  In order to remove the panel module A and the wires 70 to 72, the oil in the hydraulic jack 51 is drained from the state of FIG. 4B through the hose terminal 55, and the state transitions to the state of FIG. Then, the above-described disconnection work may be performed.

  You may comprise so that all or one part of each wire 70-72 can be wound up inside the support | pillar 50. FIG. By so doing, farming is not hindered without removing the wound portion, so that at least a part of each of the wires 70 to 72 can be left on the site as it is.

  In other words, even when at least a part of each of the wires 70 to 72 is left in the field in this way, it is included in the protection scope of the present invention. Of course, each of the wires 70 to 72 is not necessarily a single wire, and a plurality of wires may be connected in the length direction and used as each of the wires 70 to 72.

  Of course, the tension applying mechanism of this example is only a preferable example, and may be replaced with other well-known means, and such a case is included in the protection scope of the present invention.

  Next, the foundation B and the like will be described with reference to FIG. Fig.5 (a) is an elevational view which shows the foundation and support | pillar in Embodiment 1 of this invention, FIG.5 (b) is a top view of the same foundation.

  The foundation B can be arbitrarily configured as long as it does not hinder farming and has sufficient strength.

  However, in this example, the foundation B is configured as follows. That is, first, the surroundings of the installation site are excavated to dig a hole, the pile 56 is driven vertically at a level lower than the ground G, and the footing 57 is hit on the top thereof.

  As the pile 56, a well-known means, for example, H steel, a round pile, etc. can be used, and the footing 57 does not need to be a rectangle as shown in FIG.5 (b).

  Four L-shaped anchor bolts 58 are inserted into the footing 57, and the threaded portion of the anchor bolt 58 protrudes above the upper surface of the footing 57.

  Further, a rectangular base plate 60 having a larger area than that of the support 50 is fixed to the bottom of the support 50, and the base plate 60 has four through holes (not shown) through which threaded portions of the anchor bolts 58 can be inserted. Opened.

  Therefore, when the installation of the footing 57 is completed, the base plate 60 of the support column 50 is placed on the upper surface of the footing 57 while being aligned with the anchor bolt 58, and the nut 59 is screwed onto the screw portion positioned at the upper end of the anchor bolt 58. Combined, the column 50 is connected to the foundation B. After that, the soil is backfilled in the opened hole, and the level of the original ground G is raised.

  FIG. 6 is a plan view showing the vicinity of the back arm in the first embodiment of the present invention, and FIG. 7 is a perspective view showing the wire set in the first embodiment of the present invention.

  Now, as shown in FIGS. 5 (a) and 6, near the ground G at a slightly lower portion of the side surface of the support column 50, there are three hinge portions shifted by 90 degrees in accordance with the positions of the three wire locking pieces 53. 61 is provided.

  The proximal end portion of the right arm 62 is pivotally supported on the hinge portion 61 that appears on the right side of FIG. 5A, and the proximal end portion of the left arm 63 is pivotally supported on the hinge portion 61 that appears on the left side.

  Furthermore, although it does not appear as a shadow in FIG. 5A, the base end portion of the back arm 64 is pivotally supported by the hinge portion 61 on the back side.

  These arms 62 to 64 have the same length and have almost the same shape. When these arms 62 to 64 are brought close to the folding column 50 using the hinge portion 61, as shown in FIG. 5A, these arms 62 to 64 become parallel to the column 50 (that is, stand up vertically). ) Folding position.

  On the other hand, if these arms 62 are expanded using the hinge part 61, as shown in FIG. 6, these arms 62-64 will become a deployment position orthogonal to the support | pillar 50 (namely, comprise a horizontal surface).

  As can be seen from FIG. 5A, when the folding position is set, the vertical projection areas of the support column 50 and these arms 62 to 64 are small, and the influence on farming can be reduced.

  On the other hand, when power generation is performed, the distance from the support column 50 to the distal ends of the right arm 62 and the left arm 63 can be set sufficiently large as the deployment position shown in FIG.

  In the unfolded position, as shown in FIG. 6, the ring 67 provided between the tip of the right arm 62 and the right side of the back arm 64 and the tip of the left arm 63 and the left side of the back arm open in the horizontal plane. A suitable tension is applied to the outer wire 68 by operating the turnbuckle 69 attached to the outer wire 68 in the middle of the outer wire 68.

  In this way, the outer wire 68 is stretched and tension is applied, as shown in FIG. 7, when tension is applied to each of the wires 70 to 72, a moment is applied in such a direction that the upper ends of the pair of columns 50 fall inward. This works to counterbalance this moment.

  Further, as shown in FIG. 7, the wires 70 to 72 are located at positions where the wires 70 to 72 are turned 90 degrees at the proximal end portion of the support column 50 and the distal ends of the right arm 62 and the left arm 63. Is arranged around the pulley 65.

  For the convenience of illustration, in FIG. 7, the distance between the wires 70 to 72 that run in parallel between the pair of support columns 50 is shown to be shorter than the actual distance.

  If this distance is appropriately set long, the length of the first wire set composed of the first side wire 70 and the center wire 71 and the length of the second wire set composed of the center wire 71 and the second side wire 72 will be described. A sufficient thickness can be secured.

  One of the first wire set and the second wire set may be selected, the wire locking portion 43 of the panel module A may be connected to one of the selected wire sets, and the locking tool 45 may be connected to the other. As will be described later, more panel modules A are usually arranged using both the first wire set and the second wire set.

  In order to make the solar cell panel 1 of the panel module A face south, the pair of support columns 50 may be arranged so as to be separated from each other in the east and west directions, and the wires 70 to 72 may be laid out in the east and west directions.

  Next, with reference to FIG. 8, an example of the installation procedure in units of a pair of columns 50 will be described. FIG. 8 is a perspective view showing an installation process of the panel module according to Embodiment 1 of the present invention.

(Farming season)
As shown in FIG. 5 (a), the state of the farming season is close to a state where only a pair of support posts 50 are standing on the field with an interval.

  However, since the arms 62 to 64 are in the folded position, farming is not possible with a projected area that is slightly larger than the support 50, but the ratio of this projected area to the total area of the field is small.

(Power generation preparation)
In the fallow land where farming is over or where farming is not originally conducted, preparations for power generation are started. That is, first, the arms 62 to 64 are opened so as to form a horizontal plane, and are set to the developed positions shown in FIGS.

  Next, the outer wire 68 is hung on the ring 67 so that the turnbuckle 69 of the outer wire 68 can be operated. In addition, the wires 70 to 72, which end at the wire locking piece 53, are hung. At this time, the oil of the hydraulic jack 51 is not press-fitted, and as shown in FIGS. The wire locking piece 53 is left in a low position.

  In this state, the tension of the wires 70 to 72 is almost zero, and the wires 70 to 72 are soft and easy to operate.

  Therefore, as shown in FIG. 8, the panel module A is carried into the site, the folding frames 3, 5 and the canes 6, 7 are set up, and the solar panel 1 is mounted on the ground G as shown in FIG. 3. Set to make a predetermined angle θ.

  Further, the wire locking portion 43 is locked to the north wire, the locking tool 45 is locked to the south wire, and the panel module A is detachably connected to these wires.

  In the example of FIG. 8, in the first wire set including the first side wire 70 and the center wire 71, the first side wire 70 is the north side wire, and the center wire 71 is the south side wire.

  In the second wire set including the center wire 71 and the second side wire 72, the center wire 71 is the north side wire, and the second side wire 72 is the south side wire.

  In the state of FIG. 8, the connection of the panel module A with respect to the first wire set is completed, and the connection of the two panel modules A is completed in the second wire set, and the third panel module A is operated and connected. Preparations are being made.

  After the above operations are repeated and the necessary number of panel modules A are connected, oil injection into the hose terminals 55 of the struts 50 on both sides is started, and as shown in FIG. The head portion 52, that is, the wire locking piece 53 is raised to the upper limit position, and tension is applied to the wires 70 to 72.

  Note that the tension may be applied to the outer wire 68 using the turnbuckle 69 at the same time as the press-fitting of oil, or may be performed at different times before and after. Here, when the hydraulic jack 51 pulls the first wire set and the second wire set, tension in the longitudinal direction of these wire sets is applied. Further, by operating the turnbuckle 69, tension is applied to the front wire 44. The tension applied to the front wire 44 is in a direction perpendicular to the longitudinal tension. By applying the tensions orthogonal to each other, the panel module A is provided with a sufficient supporting force that can counter an external force (for example, wind force during a typhoon).

  FIG. 9 is a plan view showing an installation example of the panel module according to Embodiment 1 of the present invention.

  In an actual field, it is difficult to think of ending in one unit when a pair of columns is used as a unit, and as shown in FIG. 9, it is necessary to repeat an operation for a predetermined number of sheets, that is, a plurality of units or more. .

  It should be noted that when a plurality of sets of panel modules A are placed on the loading platform 82 of the truck 80 equipped with the small crane 81 and transported to the vicinity of the site, and each panel module A is transported to the installation location using the tiller 83, the work efficiency is good. It becomes.

(Removal and transfer)
It will be readily understood that the above power generation preparation steps may be performed in reverse order to remove the panel module A and wires.

(Summary)
From the above description, it will be understood that it does not require so much muscular strength and physical strength and is within the range that can be performed manually by a healthy elderly person or a farmer. And each part is loaded on the loading platform 82 of the truck 80, and without worrying about damaging the solar battery panel 1, it is transported to the next site (another farmland) and assembled to generate power.

  In other words, healthy elderly people can participate in the work, and the farmers and the silver generation can work for about 4 hours per day, earning income from it, and it is a moderate exercise. It can contribute to the maintenance and promotion of health.

  Thus, according to the present invention, it is possible to construct a scheme that enables “double cropping between rice and power generation” without troublesome procedures such as diversion of farmland.

(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 (a) is an elevation view showing the foundation and the support in Embodiment 2 of the present invention, FIG. 10 (b) is a side view showing the foundation and the support, and FIG. It is a top view which shows the example of installation.

  In this embodiment, the foundation B is an L-shaped retaining wall 90. As the L-type retaining wall 90, a commercially available concrete secondary product may be used.

  The most different point from the first embodiment is that the right arm 62 and the left arm 63 are not folded and fixed to the column 50. Therefore, as shown in FIG. 10B, the base end portion of the column 50 and the base end portions of the arms 62 and 63 are placed on the base plate 91, and the tip ends of the arms 62 and 63 are placed on the base plate 92. , 93 and the base plates 91 to 93 are fixed to the upper surface of the L-shaped retaining wall 90.

  As shown in FIG. 10B, the arms 62 and 63 always take the unfolded position (including the farming season) and cannot take the folded position. Therefore, it is more disadvantageous than the first embodiment in that the projected areas of the arms 62 and 63 are increased. However, in the second embodiment, the distance between the columns can be made wider than in the first embodiment. Basically, a pair of foundations will be placed on both sides of the paddy field, so there are no obstacles to farming on the inside of the pillars and foundations. Can be reduced.

  The strength of the L-shaped retaining wall 90 is large, and as shown in FIG. 11, the L-type retaining wall 90 can be installed almost at the full width of the field, and counterbalance is achieved by the back arm 64, the outer wire 68, etc. in the first embodiment. No need. In this respect, it can be said that it is more advantageous than the first embodiment. As shown in FIG. 11, when the L-shaped retaining wall 90 is arranged in the vicinity of the border of the field, it is considered that the L-shaped retaining wall 90 is useful as a soil retaining for regulating the outflow of soil as a secondary effect.

  As a whole, it can be said that the effects are almost equal in the first embodiment and the second embodiment. Even if it is configured as in the second embodiment, and even if another example in which the arms 62 and 63 are folded in the second embodiment is adopted, it is included in the protection scope of the present invention. Needless to say.

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