Description

  The present invention allows healthy elderly people and farmers to carry each part even on farmland with poor scaffolding, and after installation, structural strength performance that exceeds the standards stipulated by the Building Standards Act is obtained. It relates to photovoltaic power generation facilities for relocation between fields that do not hinder farming. 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, the tone of politicians advocating zero nuclear power is in the spotlight.

  A prominent argument against this is that it is irresponsible to make such a claim without the prospect of alternative energy.

  Japan, on the other hand, is facing a super-aging population in which elderly people over the age of 65 account for a quarter of the population. It is desirable to take measures that make people feel worthwhile, such as working for about 4 hours and earning a certain amount of income.

  As a technique for overcoming such a difficult situation, the present inventor has pondered that solar power generation is performed mainly on healthy elderly people in farmland (rice fields, fields, pastures, etc.). ing.

  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 rice fields.

  If it is such farmland, there is no need to perform troublesome procedures such as diversion of farmland. However, at the time of the original farming, the photovoltaic power generation equipment for moving between fields must be removed, and a large transport machine cannot be used around the farmland, the scaffolding is bad, Furthermore, the physical strength and arm strength of healthy elderly people are not strong. 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 requirements.

  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. That is, the photovoltaic power generation facility for moving between fields can be divided into a plurality of parts that can be placed on the platform of a light truck, for example, and each part can be carried by an elderly person manually. In addition, what is necessary is just to make it the extent which the heaviest photovoltaic power generation panel and its frame can be carried by two persons.

  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.

  Condition (3): Capable of responding to the addition or reduction of weight by water that is easy to obtain on farmland.

  Condition (4): Considering that the power purchase rate is specified, the cost of the entire photovoltaic power generation facility for moving between fields can be reduced by using commercially available inexpensive parts as much as possible. More specifically, it is desirable that many of the parts have already been mass-produced and can be purchased at a low price at a surrounding home center. If this condition (4) is not satisfied, it cannot be put into practical use, and it must be said that it is a technology whose social circumstances do not allow implementation even if technically possible.

  Condition (5): Consideration must be given so as not to damage the solar cell panel which is the main part when moving each part.

  Considering the above consideration, the conventional technology based on heavy objects such as concrete cannot be relocated itself, and is completely out of the question.

Proposals that at least partially meet the conditions (2) and (3) are described in Patent Document 1 (Japanese Patent Application Laid-Open No. 2004-6656) and Patent Document 2 (Japanese Patent Application Laid-Open No. 2004-47755).
Japanese Patent Application Laid-Open No. 2004-6656 JP 2004-47755 A

  However, the one described in Patent Document 1 has a structure in which one or all of the photovoltaic power generation panels are supported by a tank mount integrally formed of plastic or the like.

  Therefore, it must be considered that it is impossible to subdivide the tank mount so that it can be carried manually. In the end, it is impossible for farmers (often they are elderly people) and elderly people to carry huge tanks at sites with poor scaffolding, and the practicality is low and the condition (1) is satisfied. Absent.

  In order to actually mold, it is indispensable to raise a huge mold and process the tank by injection molding or the like, which does not satisfy the condition (4).

  Furthermore, when a tank is damaged such as cracks or chips and water leakage is assumed, it is difficult to quickly obtain a replacement tank because a special tank is used. In addition, it does not assume relocation between different sites, and does not satisfy condition (5).

  In the case of the one described in Patent Document 2, the condition (2) may be satisfied, but as in Patent Document 1, in order to actually mold, a huge mold is raised and the tank is processed by injection molding or the like It is essential that the condition (4) is not satisfied.

  Furthermore, as in Patent Document 1, when a tank is damaged, such as a crack or a chip, and a water leak or the like is assumed, it is difficult to quickly obtain a replacement tank because a special tank is used. It is.

  In any case, even if the techniques of Patent Document 1 and Patent Document 2 are used alone or in combination, the conditions (1) to (5) are not satisfied, and the above object cannot be achieved.

  Therefore, the present invention enables farmers and healthy elderly people to transfer each part from a poorly-grown farmland to another farmland, and after installation, structural strength performance exceeding the standards stipulated by the Building Standards Act is obtained. The purpose of this project is to provide solar power generation equipment for relocation between fields that will be removed and will not hinder farming.

  The photovoltaic power generation facility for moving between fields according to the first invention includes a solar cell panel, a frame body that holds the solar cell panel, and a pair of foundations that are arranged on the left and right sides symmetrically in the longitudinal direction of the frame body, Photovoltaic power generation for relocation between fields comprising a pair of left and right symmetrically in the longitudinal direction of the frame body, and a pair of folding frames fixed so as to be able to take a folding position in contact with the frame body and a standing position orthogonal to the frame body Each of the pair of folding frames is a base that is pivotally supported with respect to the frame by a hinge provided on the frame, and a long side that is inclined with respect to the base by a predetermined inclination angle. Each of the pair of folding frames fits in the frame body in the thickness direction of the frame body at the folding position, and the pair of foundations The bottom and the bottom A handle having an upper surface parallel to the handle and an even number of tanks having a gap through which the belt can be inserted under the handle are arranged close to each other with the position of the long side as the symmetry axis when the pair of folding frames are in the standing position. The even number of tanks are fastened with horizontal belts, and each of the even number of tanks is filled with water, and the photovoltaic power generation facility for moving between fields is further placed on each upper surface of the even number of tanks. And a hook leg that engages with at least some of the handles of the even number of tanks, is in contact with the long side of the longitudinally aligned central axis and coincides with the symmetry axis, and acts on the solar cell panel and the frame. It has a pair of foundation plates which have a groove part which transmits to a foundation, and a connection belt which fastens a pair of foundations and a pair of folding frames so that removal is possible.

  In this configuration, in the state before installation, the folding frame is in the folding position, and the solar cell panel, the frame body, and the folding frame are integrated in a substantially plate shape. Therefore, it is easy for two people to transport them even in farmland with poor scaffolding. In addition, since each of the pair of folding frames fits in the frame body in the thickness direction of the frame body at the folding position, a plurality of stacked frames are not bulky and do not damage the solar cell panel.

  Commercially available resin tanks satisfy the above definition, and can be easily transported and replaced by one person, even on farmland with poor scaffolding. If there is almost no water in the tank, the transportation is very simple. If the tank is filled with water at the time of installation, the weight of the foundation can be secured sufficiently. In general, watering is frequently performed on farmland, so water supply is easy.

  Similarly, the base plate can be easily transported by one person even on farmland with poor footing.

  A commercially available belt can also be used for the belt.

  As the farming season approaches, the assembled equipment can be disassembled, loaded onto a light truck bed, for example, and easily transferred to the next installation location.

  In short, according to this configuration, all of the above-mentioned conditions (1) to (5) can be satisfied, and a “double-cropping of rice and power generation” centered on farmers and elderly people can be realized.

  In the photovoltaic power generation facility for moving between fields according to the second invention, in addition to the first invention, two tanks adjacent to each other among the even number of tanks are connected by a vertical belt, and a pair of outer tanks are connected to the outside of the vertical belt. An extended vertical belt extending to the folding frame is provided, and the connecting belt includes the extended vertical belt.

  With this configuration, it is possible to firmly connect the foundation and the frame body using the same type of commercially available loading belt.

  In the photovoltaic power generation facility for moving between fields according to the third invention, in addition to the first invention, the pair of folding frames are connected with respect to the longitudinal direction of the frame body by the rooting material when in the standing position.

  With this configuration, the folded frames can be firmly connected.

  In the photovoltaic power generation facility for moving between fields according to the fourth invention, in addition to the first invention, the pair of folding frames are positioned in the vertical projection plane of the solar cell panel in both the standing position and the folding position. .

  With this configuration, the space for installing the solar cell panel is not obstructed by other members, and a good space factor can be obtained.

  According to the present invention, all of the above conditions (1) to (5) can be satisfied, and a “double-cropping of rice and power generation” centered on elderly people and farmers can be realized.

(Embodiment 1)
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a bottom view of the photovoltaic power generation apparatus according to Embodiment 1 of the present invention.

  As will be described in detail later, this device is designed to be easily disassembled for easy transportation, installation and removal. The solar cell panel 1, the frame body 2, and the folding frames 3, 5 are used as the main material. To do.

  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).

  FIG. 21 is an explanatory diagram of attachment of the frame body according to the first embodiment of the present invention, and FIGS. 22A to 22C are explanatory diagrams of attachment of the frame body according to the second embodiment of the present invention.

  Here, if the solar cell panel 1 and the frame 2 are attached as shown in FIG. 21 or FIG. 22 (a) to FIG. 22 (c), most of the commercially available solar cell panels 1 can be handled.

  In particular, the folding frames 3 and 5 are all housed in the frame body 2 in the thickness direction of the frame body 2 at the folding position as shown in FIG. Therefore, for example, it is not bulky even if a plurality of solar battery power generation devices (solar cell panel 1, frame body 2, folding frame 3, 5, etc.) are stacked in the thickness direction of the light truck, and the folding frame 3 5 does not damage the solar cell panel 1. However, since the essence of the present invention does not lie in such an installation procedure, further detailed description is omitted.

  Now, 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. However, by operating the hinge 2 a, the folding frames 3 and 5 are raised from the state of FIG. 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 folding frame 3 is preferably formed by bending a pipe having a diameter of about 14 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. 6 and the like).

  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. To be precise, the folding frame 3 has a trapezoidal shape having a base 31, a short side 33, a long side 34, and an upright 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 G as shown in FIG. However, 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 from the front and back of 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 back is improved.

  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.

  A portion between the inner long side 36 and the long side 34 is a connecting portion, and reinforcing rings 37 and 38 bent in a square shape are fitted on both sides thereof.

  The T-shaped side portion of the binding material stopper 39 made of a substantially T-shaped plate is fixed to the central portion of the reinforcing portion.

  A protruding piece 40 extending in parallel with the long side 34 and the inner long side 36 is formed at the center of the rooting material stopper 39, and a wedge hole 40 a is opened at the central portion of the protruding piece 40.

  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.

  A brace 32 for locking a reinforcing material 83 (see FIG. 6), which will be described later, is fixed near the reinforcing material 42 of the bottom 31, and a locking portion 6 a for locking the cane 6 is provided. Provided.

  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, when the folding frames 3 and 5 are vertically raised from the state of FIG. 1 with respect to the frame 2, the canes 6 and 7 are also raised, and the tips of the canes 6 and 7 are attached to the locking portions 6a and 7a. The folding frames 3 and 5 can be kept standing vertically with respect to the frame body 2 (see also FIG. 7).

  Next, with reference to FIG. 2 to FIG. 7, the base part below the folding frames 3, 5 and the connection procedure between the base part and the folding frames 3, 5 will be described.

  FIG. 2 is a plan view showing the foundation in the first embodiment of the present invention. In FIG. 2, a broken-line rectangle indicates the position of the outer edge portion of the frame body 2. A pair of left and right pedestals are installed in this rectangle.

  As shown in FIG. 2 (a), two commercially available tanks (usually for storing kerosene and having a volume of 18 to 20 liters) 60 made of a resin such as polyethylene are disposed horizontally. These are aligned and connected by a vertical belt 43.

  As will be described later, the two tanks 60, 60 connected by the vertical belt 43 in this way are arranged vertically, and for convenience, four tanks 60 are connected by the horizontal belt 45, and the four tanks 60 form one basic unit. Configure.

  As will be described later, in this embodiment, various belts are used, and any belt may be a commercially available loading lashing belt (width of about 50 mm). Therefore, a high-quality belt that exhibits sufficient strength can be obtained and exchanged very cheaply and easily.

  The tank 60 has a handle 62 having an upper surface 62a parallel to a bottom surface 61 (see also FIG. 6) placed on the ground G, and a gap 63 through which a belt can be inserted is opened below the handle 62. It is optional if it exists.

  A commercially available plastic tank satisfies this condition and can be used as the tank 60 of this embodiment.

  If a commercially available plastic tank is used, the installation and removal of the object can be realized without using a huge cost and labor for raising and molding a new mold. Even if some tanks are damaged such that they cannot be used, they can be recovered simply by purchasing a tank of the same shape at a local home center at a low price. In addition, belts can be obtained and exchanged as well.

  The tank 60 is provided with a pouring inlet cap 64. If the cap 64 is opened and water is poured into the tank 60, the weight of the tank 60 increases, and it becomes about 18 to 20 kilograms per tank 60. Can be used as a weight.

  On the other hand, if the cap 64 is opened to discharge water, the tank 60 can be lightened and can be easily transported to the next site.

  Here, the water as the liquid to be taken in and out of the tank 60 may be tap water, or agricultural water or rain water as long as it is farmland. Alternatively, a liquid other than water may be used, but water that has little influence on farmland (usually present) is most preferable when it is considered to be released on farmland, as will be described later.

  As shown in FIG. 2B, when the connection of the tanks 60 is completed, the base plate 70 is placed on the upper surfaces 62 a of the grips 62 of the four tanks 60.

FIG. 3 (a) is a plan view of the base plate in Embodiment 1 of the present invention, and FIG. 3 (b) is a front view of the base plate.

  As shown in FIGS. 3A and 3B, the base plate 70 is configured as follows. The base plate 70 is preferably made of resin, but can also be made of a lightweight and strong metal (for example, aluminum).

  The base plate 70 has a plate portion 71 which is a rectangular horizontal plate as a main material. On the upper surface of the plate portion 71, protrusions 72 and 73 are provided in parallel with the central line in the longitudinal direction with a space therebetween.

  Between the protrusions 72 and 73, a groove portion 74 having a bottom portion at the same level as the upper surface of the plate portion 71 is formed.

  The width of the groove 74, that is, the interval between the protrusions 72 and 73 is set to be slightly wider than the diameter of the steel pipe constituting the folding frames 3 and 5.

  On one of the longitudinal edges of the plate portion 71, a hanging leg portion 75 that is simply bent vertically downward with respect to the plate portion 71 is formed.

  Further, a hook leg portion 76 is formed at the other edge in the longitudinal direction of the plate portion 71 so as to be bent vertically downward with respect to the plate portion 71 and further bent in parallel with the plate portion 71.

  FIG. 4 is a longitudinal sectional view showing the vicinity of the base plate in the first embodiment of the present invention. As shown in FIG. 4, the hook leg portion 76 has a shape that is bent in a C shape in the cross section.

  As shown in FIG. 2 (a), when the base plate 70 is placed on the four tanks 60, the hanging leg portion 75 simply hangs down to the side of the handle 62. The posture is such that the handle 62 wraps around the side and below.

  As a result, the base plate 70 is temporarily fixed to a unit including the four tanks 60.

  Further, the lowest point (that is, the long side 34) of the folding frames 3 and 5 is inserted into the groove portion 74 of the base plate 70, and the load of the solar cell panel 1, the frame body 2, etc. is passed through the base plate 70. , The handle 62, that is, the unit composed of four tanks 60.

  FIG. 6 is a side view of the photovoltaic power generation facility for moving between fields in Embodiment 1 of the present invention.

  As will be described in detail later, as shown in FIGS. 4 and 6, the outer edge vertical belt 44 provided outside the vertical belt 43 extends to above the base plate 70, is parallel to the long side 34, and from the long side 34. In addition, the parallel portion 41a of the reinforcing member 41 positioned above is wound and fastened to the four tanks 40.

  Thus, by constructing the base plate 70 of this embodiment and transmitting the load rationally, it is possible to use a member such as a commercially available plastic tank or a lashing belt that can be obtained easily and inexpensively, and a severe typhoon or the like. The solar battery panel 1 can be supported stably even under weather conditions, and when moving, each member is disassembled into pieces and each part is weighted so that it can be carried manually. be able to.

  This point is extremely important in a field where the surrounding road is narrow and can only be traveled by light trucks, such as farmland (in other words, an environment where a large machine for transportation cannot be used).

  Next, various reinforcing points will be described.

  FIG. 5A is a front view of the root binding material according to Embodiment 1 of the present invention, FIG. 5B is a relationship diagram between the root binding material and the projecting piece, and FIG. 5C is the same wedge. It is a front view.

  The rooting material 80 is preferably made of an aluminum square pipe. This is because it is lightweight and easy to carry and has sufficient strength.

  The rooting material 80 is shorter than the length in the longitudinal direction of the frame member 2 and slightly longer than the distance between the centers of the units including the four tanks 60. Then, the pair of slits 81 are opened in a direction orthogonal to the longitudinal direction of the rooting material 80 with a distance of the central feeling.

  As shown in FIG. 4, a rooting material 80 is bridged on the unit so that the position of the slit 81 matches the center, and as shown in FIG. 5B, the protruding piece 40 of the rooting material stopper 39. Is inserted into the slit 81.

  Then, the tip end side of the wedge hole 40 a of the protruding piece 40 is exposed to the outside of the rooting material 80.

  A wedge 82 having a tapered portion as shown in FIG. 5C is driven into the exposed wedge hole 40 a, and a pair of units are connected using a rooting material 80.

  FIG. 7 is a rear view of the photovoltaic power generation facility for relocation between the fields. As shown in FIG. 7, by using bracing 32 or the like (details will be described later), an oblique reinforcing member 83 is bridged in an X shape to perform further reinforcement.

  If any of the eight tanks 60 has enough water at any of the points completed so far, the total weight will be about 160 kilograms. Even under severe weather conditions such as typhoons, the solar panel 1 can be It can be supported on the ground G in a stable state.

  Next, a procedure for installing a large number of photovoltaic power generators according to the present embodiment on farmland will be described with reference to FIGS. Of course, in addition to this, a fallow land, a field, a meadow, and the like can be selected as the farmland, and such a case is included in the present invention.

  The rice field after rice harvesting was taken as an example because it is used as a normal rice field during the period from rice planting to rice harvesting in the rice field, and from rice harvesting to before rice planting, it generates electricity in the rice field.

  In this way, the so-called “double-cropping of rice and power generation” can be operated, and troublesome procedures such as diversion of farmland are not required, so the profit is great. In other words, power can be generated on the farmland itself.

  In fact, the present inventor does not know an example in which double cropping between rice and power generation is actually performed.

(Process 1: Ground maintenance)
FIG. 8 is a perspective view of the farmland in the first embodiment of the present invention. First, as shown in FIG. Stumps remain in the rice field after rice harvesting, and the ground is flat as a whole, but there are many irregularities.

  In order to increase the activity of the soil when planting rice the next time, it is desirable to put a cultivator in the rice field and sow a rice stump and mix it with the land (not shown). If it carries out like this, a shoot, a stem, and a leaf will grow from the harvested rice, and the solar cell panel 1 will be blocked, and the situation where power generation efficiency falls can be prevented.

  It is desirable to plow three times in total, but it is not necessary to plow at this point, it may be plowed before rice planting, and even if it does not affect rice cultivation.

  Then, as shown in FIG. 8, on the farmland 90, a small heavy machine 92 equipped with an attachment such as a rake 91 is run to remove unevenness and level the cultivated soil. Such a small heavy machine 92 is configured to be suitable for traveling on the farmland 90, and since a commercially available product or a leased product can be used, the work is easy.

  FIG. 11 is an explanatory diagram of arrangement of units in the first embodiment of the present invention, and FIG. 23 is a layout diagram of farmland in the first embodiment of the present invention. Next, as shown in FIG. 11 and FIG. 23, a ground rope 93 is stretched vertically and horizontally on the farmland 90 to mark the place where the tank 60 is installed.

  Further, it is only necessary to install the tank 60, but it is desirable to compact the ground with a ramp plate (not shown) and level the ground.

  Further, preferably, the level of the installation location of the tank 60 is confirmed using a level or the like, and adjustments such as removing or adding soil are performed as necessary.

  The ground maintenance is now complete.

(Process 2: Basic composition)
FIG. 9 is a perspective view of the tank according to Embodiment 1 of the present invention. As shown in FIG. 9, two tanks 60 are arranged so that their longitudinal directions coincide with each other, and are connected by a vertical belt 43.

  Although not mentioned in FIG. 6 and the like, the vertical belt 43 is formed in a bag-like shape with a lateral belt thread 43a at two locations above and below the side surface of the tank 60, and between the two belt loops 43a. The base end portion of the extended vertical belt 44 is sewn. Near the bottom of the tank 60, a hook 43b for locking the reinforcing member 83 is provided.

  A fastening tool 46 having a ratchet mechanism (not shown) is attached to the front end portion of the extended longitudinal belt 44. The fastening tool 46 is inserted on the opposite side of the side shown in FIG. A mating portion (insertion belt 44a; see also FIG. 15) of the extended longitudinal belt 44 is disposed.

  It is preferable to put about 3 to 5 liters of water in advance in the tank 60 because the stability is improved and the tank 60 is not so heavy.

  FIG. 10 is a perspective view of a unit according to Embodiment 1 of the present invention. Next, as shown in FIG. 10, two sets of FIG. 9 are arranged in the longitudinal direction of the tank 60 (for convenience, four tanks 60 are combined) into one basic unit.

  That is, the lateral belt 45 is passed through the belt loop 43a, and the periphery of the four tanks 60 is horizontally wound and tied so as to be two steps up and down.

  Two such units are made on the left and right sides, and are used as the foundations for supporting the solar cell panel 1 and the frame 2.

  Next, as shown in FIG. 23, the ground rope 93 is stretched vertically and horizontally and a pair of left and right units are arranged in a matrix.

  One rectangle partitioned by the ground rope 93 is an installation space for one solar cell panel 1, but if it is about one rice paddy, about three parallel passages 95 are secured and secured passages. 95 is preferably arranged so that the tractor 96 can travel. In addition, the width | variety of the channel | path 95 is preferable about 60 centimeters, A person's movement, mowing, etc. are attained. Here, mowing is necessary to prevent the situation where the grass grows and blocks light in the field of farmland (especially the passage 95 that does not enter the shadow of the solar cell panel 1) and the power generation efficiency by the solar cell panel 1 decreases. Because there is.

(Embodiment 3)
In the third embodiment, the configuration of the base plate 100 is different from those in the first and second embodiments. Hereinafter, only differences from Embodiments 1 and 2 will be described in Embodiment 3, but items not particularly mentioned are the same as those in Embodiments 1 and 2.

  Here, Fig.24 (a) is a top view of the base plate in Embodiment 3 of this invention, FIG.24 (b) is a perspective view of the base plate.

  FIG. 25 (a) is a plan view of the basket in Embodiment 3 of the present invention, FIG. 25 (b) is a front view of the basket, and FIG. 25 (c) is a plan view of the tank.

  Fig.26 (a) is a front view of the eaves in Embodiment 3 of this invention, FIG.26 (b) is a front view of the tank, FIG.26 (c) is a side view which shows the same water supply state.

  The base plate 100 according to the third embodiment has a round hole 103 that is placed on each upper surface of the tank 60 and opens so that the spout 65 of the tank 60 can be inserted.

  The foundation plate 100 has a groove 106, which is in contact with the long side 34 of the folding frames 3, 5 and transmits the load acting on the solar cell panel 1 and the frame 2 to the foundation.

  Hereinafter, it demonstrates more concretely, referring FIGS. 24-26. In the first and second embodiments, the base plate 70 is connected to the tank 60 using the hook leg portion 76 of the base plate 70.

  On the other hand, in the third embodiment, as shown in FIG. 24B, the base plate 100 includes a central horizontal portion 101 and two inclined portions 102 inclined downward from both ends of the horizontal portion 101. Then, in accordance with the positions of the spouts 65 (eight in total) provided in the four tanks 60 located directly below the base plate 100, the round holes 103 having a slightly larger diameter than the spouts 65 (eight in total) ) Has been established.

  The spout 65 is normally closed when the cap 64 is screwed. Similarly, as shown in FIG. 24A, the round hole 103 formed in the inclined portion 102 has a round hole 103. It is preferable that the spout 65 is exposed outwardly, the washer 66 is fitted to the outer peripheral portion of the spout 65 from the outside of the inclined portion 102, and the cap 64 is screwed into the screw portion of the spout 65 from above the washer 66.

  Similarly, the spout 65 is exposed from the round hole 103 of the horizontal portion 101. However, an insect net (not shown) is provided in the spout 65 of the central portion 101 so that insects, dust, and the like do not enter the tank 60. It is recommended that the cap 64 is screwed into the spout 65 after mounting the eye plate with a tension.

  Thus, when the cap 64 is screwed into the spout 65 exposed from the round hole 103 of the inclined portion 102, the base plate 100 and the four tanks 60 are integrated.

  Furthermore, the lower ends of the gate-shaped handles 104 and 105 are fixed to the center of the horizontal portion 101 so as to be line symmetric with respect to the center line of the horizontal portion 101 as an axis of symmetry. Between these grips 104 and 105, a groove portion 106 is formed, and the long side 34 of the folding frames 3 and 5 is inserted into the groove portion 106 in the same manner as in the first and second embodiments. 44 and the like, the folding frames 3 and 5 can be connected to the foundation having the tank 60 as a main component.

  Once the folding frames 3 and 5 are connected to the foundation, the groove 106 transmits the load acting on the solar cell panel 1 and the frame body 2 to the foundation.

  On the other hand, if the extended longitudinal belt 44 or the like is removed, the cap 64 is screwed into the spout 65 of the tank 60 through the round hole 103. For example, the amount of water in the tank 60 is small or not at all. In this case, if the operator holds the handles 104 and 105, the four tanks 60 can be lifted up and transported together, which is very convenient.

  Next, the water injection work to the tank 60 will be described with reference to FIGS. If the water in the tank 60 is insufficient, water may be poured into the tank 60 one by one.

  However, if a jar 107 as described below is used, the efficiency can be improved because water can be poured into the four tanks 60 together. First, as shown in FIGS. 25A and 25B, a cylindrical basket 107 having an open upper end is prepared.

  In the illustrated example, the flange 107 includes a cylindrical tube portion 108 and a disk-shaped bottom plate 109. However, the flange 107 may be formed in a cylindrical shape having a rectangular cross section, or may be formed in a funnel shape like a hopper.

  As shown in FIG. 26 (c), in a state where the base plate 100 is removed from the four tanks 60, the position of the four spouts 65 located at the position of the horizontal portion 101 of the base plate 100 is adjusted. As shown in (a), a round hole 110 is formed in the bottom plate 109.

  Then, as shown in FIG. 25 (b), a male screw socket 111 (internally hollow and shaped to allow water flow) is inserted into the round hole 110 from above the round hole 110, From the lower side of 107, the injection tube 113 with the female screw cap 112 mounted on the top is abutted against the male screw socket 111, and the female screw cap 112 is screwed into the male screw socket 111, thereby attaching the injection tube 113 to the bottom plate 109 of the flange 107. As shown in the drawing, the water injection pipe 113 is preferably formed in a tapered funnel shape.

  Furthermore, with the cap 64 removed from the four spouts 65 at the position of the horizontal portion 101 of the base plate 100, four water injection pipes are inserted into the four spouts 65, respectively, The water supply pipe 115 is set. Thereafter, if the water is discharged from the water supply pipe 115 to the cylindrical portion 108 of the rod 107, the water can be supplied to the four tanks 60 almost evenly.

  When the supply of water is completed, the four tanks 60 that are heavier and containing water are not moved, and at that position, the long sides 34 of the folding frames 3 and 5 are set in the grooves 106 of the foundation plate 100 and extended outwardly. If the folding frames 3 and 5 are fixed to the foundation by the vertical belt 44 or the like, power generation can be started immediately. In the above operation, the foundation plate 100 may be temporarily removed, but it is desirable to perform the operation with the foundation plate 100 attached. Then, for example, even when the lateral belt 45 is loosened or removed, the four tanks 60 are integrated by the base plate 100, so that they can be handled together and work efficiency is improved. .
