Description

  The present invention relates to a photovoltaic power generation unit that can be installed in a place with different installation conditions to generate power and can be easily moved. In detail, a solar power generation panel is installed on the top of an easily transportable container unit, and the transport container unit is fixed to a screw pile by a fixing means so that the installation and disassembly can be easily performed. It relates to a photovoltaic unit.

  Carbon dioxide emissions are required to be suppressed as a countermeasure against global warming, and a feed-in tariff system for power generated by solar power generation has begun. Power generation using renewable energy has been expanded. Solar power generation systems that use solar energy, which is an inexhaustible source of renewable energy, are installed on large premises with large-scale mega-solar power generation systems that have a capacity of several megawatts. .

  Such a large-scale photovoltaic power generation system generally takes a long construction period and requires a vast site for its installation, so it is often installed in an area where development is not progressing. However, the power generation by solar panels is easily influenced by the environment of the installation location. In mountainous areas and northern areas of Japan where there is a lot of snow, solar power generation installed in that area can be secured. The panel is filled with snow and has a problem that it is difficult to ensure stable power generation. In addition, when the angle of the photovoltaic power generation panel was increased to take measures against snow cover, the photovoltaic power generation panel might fall over due to strong winds.

  In the future, photovoltaic power generation units will be installed in a wide area, but many of the conventional photovoltaic power generation devices are not suitable for transportation, and it is difficult to move to other areas to generate power. there were. On the other hand, the possibility of the occurrence of a large-scale disaster and the possibility of damage to a wide area have been pointed out. In such a case, power is supplied from the surrounding area to the affected area due to power shortage, but among the photovoltaic power generation units that are installed in a distributed manner, solar power generation is performed from the area where power is available to the affected area. It is necessary to move the unit quickly and utilize power without transmission loss.

  The present invention uses a screw pile so that a solar power generation panel is placed on the upper part of a container unit for transportation that is easy to move by pulling public roads, and can be easily installed in a place where installation conditions are different. It is a photovoltaic power generation unit in which the screw pile and the transport container unit are fixed through fixing means that are supported and position-adjustable.

  When installing a solar power generator in an area with a lot of snow, a foundation of reinforced concrete that was high enough to prevent the power generation panel from being buried in the snow was provided. However, if a reinforced concrete foundation with a high height is installed, the construction period will be prolonged, the construction cost for the foundation work will be high, and a large amount of concrete waste will be generated when the solar power generation device is removed. .

  Document 1 discloses a technology of a solar power generation system in which a plurality of solar cell arrays are installed. This document discloses a technology for supporting an upper structure on which a photovoltaic power generation panel is placed in a state in which a steel pipe pile is used as a support pile and an upper portion thereof is protruded to a position higher than the ground. In this document, the piles are appropriately selected according to the size of the gantry and the like, and the shape and size according to the superstructure are set. According to this technology, a photovoltaic power generation panel will be installed after the base is built on the upper part of the support pile placed on the ground, which requires labor-intensive field work and the construction period is prolonged. There was a problem that the technology was not suitable for movement.

  Reference 2 discloses a technique for providing a foundation structure for a gantry that is low in construction cost, can be installed with a solar cell array with simple construction, and has a wind load countermeasure. Yes. According to the technique of Document 2, a support pile having an arrowhead at the tip is driven into the ground, and a support portion having a diameter larger than the diameter of the support pile is supported on the upper portion of the support pile by a concrete block having a hollow inside. A technique is shown in which the inside of a cavity is solidified with concrete and buried in the ground, and a support pillar is fixed to a support pile.

  And it is supposed that the excavation force by a wind load is supported by an arrowhead part, and only a dead weight is supported in a support part, cost is low, and underground excavation decreases. However, with this technique, it takes a long time to harden the concrete, and when removing it, it is necessary to leave or pull out the arrowhead that can withstand pulling out by wind load. There was a problem that it was left behind or removal work was difficult, and it was not a technique suitable for movement.

  In Document 3, paying attention to the fact that used transport container units are sturdy and are used in simple stores and warehouses, a photovoltaic power generation panel above the substantially horizontal flat roof of the transport container unit Is placed. However, it took time and effort to connect the steel struts and the scaffolding pipes with a free clamp. In addition, a base is previously formed from concrete, and the transport container unit is fixed to the base via a raised plate. Even with this technology, it takes a long time to harden the concrete, and it takes time and labor to assemble the pipe, and the waste of concrete is generated at the time of removal, so it takes time to disassemble the pipe. It was not a technology that could be moved to.

  In Reference 4, as a technology to install a solar power generation panel on a pedestal so that it can tilt, it can be used even in winter in snowy areas by simply changing the inclination of the solar power generation panel according to the sunshine angle according to the season. The technology made possible is disclosed. However, the photovoltaic panels are supposed to be installed on a rectangular frame assembled on a concrete base, and it takes a long time for the concrete to harden. Has occurred, and there is a problem that this technique cannot be easily moved.

  In Reference 5, a photovoltaic power generation panel is installed in a direction perpendicular to the ground, a reflecting mirror is used, and the sunlight reflected by the reflecting mirror is applied to the photovoltaic power generation panel. A technology of a solar power generation device that is not hindered is disclosed. However, according to the technique of Document 5, the photovoltaic power generation panel itself may be buried by snow. Further, in order to capture sunlight according to the season, it is necessary to provide a plurality of reflectors so as to be able to cope with each season, and a large site is required for the installation of the reflectors. Even with this technology suitable for the winter season, there is a problem that not only the photovoltaic power generation unit cannot be easily moved, but also the limited site cannot be used effectively.

The base 52 may have a circular cross section as shown in FIGS. 2 and 3, or a rectangular cross section.

  The locked portion 60 on the insertion side of the twist lock is formed in a substantially box shape, and an insertion hole 63 having a size for storing the lower portion 58 of the locking portion 50 is formed in the bottom portion 62. Although not shown in the drawing, the locked portion 60 is fixed to the vicinity of the corner of the shipping container unit 10 by welding or the like. When the size of the shipping container unit 10 is large, the number of locked portions that are fixed to the bottom of the shipping container unit 10 may be increased.

  Here, the operation of the twist lock will be described with reference to FIG. 2A shows a state before the locking portion 50 is mounted on the locked portion 60, and FIG. 2B shows a state where the locking portion 50 is mounted on the locked portion 60. FIG. It is a figure explaining. Before the operation handle 56 is operated, the lower portion 58 of the forward rotation portion 51 is disposed so as to face substantially the same direction as the insertion hole 63 provided in the bottom portion of the locked portion 60. Further, the insertion hole 63 has a shape that forms a horizontal cross section that matches the lower portion 58 of the forward rotation portion 51. The covering portion 50 is inserted into the locked portion 60 by covering the transport container unit 10 from above the forward rotation portion 51.

  By rotating the operation handle 56 around the shaft portion 55, the bottom end portion of the lower portion 58 having a substantially rectangular shape of the forward rotation portion 51 is hooked on the peripheral top portion of the insertion hole 63, and is locked. The part 50 is locked so as not to be detached from the locked part 60. On the other hand, by reversing the operation handle 56, the lower portion 58 is aligned with the position of the insertion hole 63 so that the locked portion 60 is lifted from the locking portion 50, and the transport container unit 10 is moved upward from the pile body 30. It can be pulled out and detached.

  The box 53 is fixed by welding to a plate 80 made of a steel plate and having a disk shape. Here, the plate 80 will be described with reference to FIG. A plurality of second long holes 81 having an arc shape are formed in the plate body 80 around the direction in which the pile shaft 35 of the pile body 30 extends. The width of the second long hole 81 is the width of the bolt 82.

  The plate body 80 is overlapped with the flange portion 32 of the pile body 30. The plate body 80 is a top portion of the flange portion 32 so that a plurality of through holes through which the bolts 82 pass are provided in any of the first elongated holes 34 and the second elongated holes 81 extending radially of the flange portion 32. The position is adjusted along. Bolts 82 are inserted into the respective through holes and temporarily fixed. Next, in this state, the position of the tip turning portion 51 of the locking portion 50 is adjusted so as to face the insertion hole 63 of the locked portion 60 formed at the bottom corner of the transport container unit 10. . Then, a plurality of bolts 82 are screwed into the nut 83 and fixed in a state where the forward rotation portion 51 is inserted into the insertion hole 63. The operating handle 56 is operated from the open window 54 located on the side of the locking portion 50 to rotate the forward rotation portion 51 to fix the locking portion 50 to the locked portion 60 (see FIG. 2).

  Thereby, in order to arrange the height of the top part of the pile body 30 to the same height, the orientation of the first long holes 31 extending radially of the flange part 32 included in the pile body 30 is not uniform. In addition, even if the top position of the pile body 30 is slightly shifted from the position of the bottom corner of the transport container unit 10, the transport container unit 10 can be fixed to the pile body 30. It is said. Thereby, the locking part 50 can be fixed to the locked part 60, and the transport container unit 10 can be easily fixed to the pile body 30.

  By providing the plate body 80, the transport container unit 10 and the pile body 30 can be fixed without directly welding the locking body 50 to the flange portion 32 of the pile body 30. Therefore, when the pile body 30 is pulled out, if the plate body 80 is removed and the screw pile is reversed in the direction opposite to that at the time of pile body embedding, it can be pulled out from the ground, and the removal work is easy. Moreover, since the plate body 80 to which the pile body 30 and the locking body 50 are welded can be reused as it is, even when the photovoltaic power generation unit 100 is removed, no waste material is produced.

  The separation distance adjusting means that is included in the fixing means 40 and adjusts the separation distance generated between the flange portion 32 and the locking portion 50 will be described with reference to FIG. When the construction error occurs and the pile body 30 is lower than the predetermined position and lower than the other piles, the distance between the bottom portion of the transport container unit 10 and the flange portion 32 is different from the other. The distance is greater than the distance between the pile and the bottom of the transport container unit 10, and a gap is generated between the plate body 80 and the flange portion 32 when the locking portion 50 is disposed.

  In order to eliminate the gap, the plate body 84 that forms a spacer having the same shape as the plate body 80 is overlapped along the bottom of the plate body 80 to eliminate the separation distance as the separation distance adjusting means. Thereby, even if the tip of the pile body 30 is obstructed by a rock or the like in the ground and the height of the top of the pile body 30 toward the corner position of the container unit 10 for transportation may be uneven, There is no gap between the container unit 10 and the pile body 30, and the pile body 30 and the transport container unit 10 are firmly fixed via the fixing means 40.

  In Example 2, with reference to FIG. 5, the photovoltaic power generation unit 200 provided with the 2nd photovoltaic power generation panel 22 separately from the 1st photovoltaic power generation panel 21 pivotally supported by one side. Will be explained. Since the configuration other than the second photovoltaic power generation panel 22 disposed on the side surface of the transport container unit 10 and slidable upward is the same as that of the first embodiment, the configuration different from that of the first embodiment is used here. This will be described in detail.

  In the photovoltaic power generation unit 200 of the second embodiment, the second photovoltaic power generation panel 22 extends vertically along the slide rail 24 from the facing roof ridge 12 extending parallel to the roof ridge 11.

  Here, with reference to FIG. 5, the operation of the first and second photovoltaic panels arranged in the photovoltaic unit 200 will be described. FIG. 5A is a diagram illustrating a state where the photovoltaic power generation unit 200 is transported and moved. At the time of movement, the first photovoltaic power generation panel 21 is lowered on the roof surface of the transport container unit 10 and the second photovoltaic power generation panel 22 is slid downward. As a result, the first photovoltaic power generation panel 21 does not protrude upward, and the second photovoltaic power generation panel 22 does not protrude greatly from the transport container unit 10 and can be easily moved on the trailer. It becomes.

  Here, description will be made with reference to FIG. FIG. 5B is a diagram showing a sliding operation of the second photovoltaic power generation panel 22 when the snow cover 92 is small. In the photovoltaic power generation unit 200 of the second embodiment, the direction of the second photovoltaic power generation panel is set to a different side from the first photovoltaic power generation panel 21 that faces the direction in which the direct sunlight 90 of the sun is directly received. It is provided for. However, when there is a reflection reflected by another object, for example, snow, the indirect light 91 that is the reflection light can be received by the second photovoltaic power generation panel 22 and the power generation amount of the entire photovoltaic power generation unit is increased. Can be made.

  Here, description will be given with reference to FIG. FIG. 5C is a diagram showing a sliding operation of the second photovoltaic power generation panel 22 when there is a lot of snow 92. When there is a lot of snow 92, the second photovoltaic panel 22 is slid upward to prevent the second photovoltaic panel 22 from being buried in the snow 92, and the second photovoltaic panel cannot be generated. Can be prevented. Furthermore, even if snow accumulates on the first photovoltaic power generation panel 21 and the first photovoltaic power generation panel 21 cannot generate power, the first solar power generation panel 22 can generate power by using the power generated by the second photovoltaic power generation panel 22. It is possible to cause the first photovoltaic power generation panel 21 to function by heating the photovoltaic power generation panel 21 to melt snow, and sliding the snow from the power generation surface.

  In Example 3, with reference to FIG. 6, the upper edge of the second photovoltaic power generation panel 22 is pivotally supported along the roof side ridge 12 of the transport container unit 10 and is vertically The photovoltaic power generation unit 300 that is slidable in the direction will be described. The second photovoltaic power generation panel 22 disposed on the side surface of the transport container unit 10 has an opposite roof side ridge 12 extending parallel to the roof side ridge 11 to which the first photovoltaic power generation panel 21 is fixed. And is rotatably supported by the shaft body 71. The shaft body 71 is supported by the housing 25 and is slidable in the vertical direction along the slide rail 24.

  Here, with reference to FIG. 6, the effect | action of the 2nd photovoltaic power generation panel 22 is demonstrated. FIG. 6A is a diagram showing the transportation container unit 10 when it is moving. The first photovoltaic power generation panel 21 and the second photovoltaic power generation panel 22 are arranged along the side surface of the transportation container unit 10 by lying down on the roof surface of the transportation container unit 10. The second photovoltaic power generation panel does not protrude greatly from the transport container unit 10 and can be easily moved on the trailer.

Here, description will be made with reference to FIG. 6B and FIG. FIG. 6B is a diagram showing a position where the second photovoltaic power generation panel 22 is slid when there is little snow 92 (not shown in FIG. 6), and FIG. 6C is a diagram showing the position when there is much snow. It is a figure which shows the position which slides the photovoltaic power generation panel 22 of 2. FIG.

  When the solar power generation unit is moved or when the reflected indirect light 91 is received, for example, when the indirect light 91 reflected from a small amount of snow is received, the second solar power generation panel 22 is provided on the side surface of the transport container unit 10. (See FIG. 6B). Further, the position of the second photovoltaic power generation panel 22 may be adjusted to an appropriate height at which the indirect light 91 can be received according to the amount of snow 92. On the other hand, when there is a lot of snow, the casing 25 that supports the second photovoltaic power generation panel 22 is slid upward along the slide rail 24 (see FIG. 6C). By sliding the lower edge of the second photovoltaic panel 22 to the vicinity of the roof side ridge 12 of the transport container unit 10, the second photovoltaic panel 22 is not buried in snow. Even when there is a lot of snow, the second photovoltaic power generation panel 22 can receive the indirect light 91, and the amount of power generation in winter can be increased.

  On the other hand, although the figure is omitted, in the season without snow, the second photovoltaic power generation panel 22 is directly connected to the sun at the reference position of the shaft body 71 on the roof side ridge 12 of the transport container unit 10. The light 90 is rotated in such a direction that it can be lit. The amount of power generation can be increased by using the direct light 90 and generating the second solar power generation panel as well.

  Here, description will be made with reference to FIG. FIG. 6D is a diagram showing a state in which the second solar power generation panel 22 is slid upward and rotated along the shaft body 71 so that the power generation surface faces the sun in a season without snow. is there. The shaft body 71 that pivotally supports the upper edge of the second photovoltaic power generation panel 22 is supported by the housing 25 along the slide rail 24 extending in the vertical direction so as to be slidable in the vertical direction. The second photovoltaic power generation panel 22 is slid up and down along the rail 24, and the inclination angle can be changed. The position of the power generation surface of the second solar power generation panel 22 is set higher than the position of the power generation surface of the first solar power generation panel 21, and the shadow of the first solar power generation panel 21 is shaded by the second solar power generation panel. If it is not applied, it is possible to generate power with two power generation panels.

  The action of warming the first photovoltaic power generation panel with the electric power from the second photovoltaic power generation panel 22 and sliding off the snow canopy is the same as that of the photovoltaic power generation unit of the second embodiment. The rotating mechanism of the second photovoltaic power generation panel 22 may be a known hinge, electric jack or the like (not shown), and the shaft body may be divided.

  Further, the housing 25 on which the shaft body 71 to which the photovoltaic power generation panel 22 is fixed is slid upward is slid along the slide rail 24. The sliding means is not particularly limited, for example, by a known driving means using a storage battery installed in the transport container unit 10 as a power source. The position of the first photovoltaic power generation panel 21 is obtained by rotating the second photovoltaic power generation panel 22 around the shaft body 71 by a known rotation mechanism in a state where the casing 25 is slid upward. Instead, the position of the second photovoltaic power generation panel 22 can be set to a high position so that the direct sunlight 90 of the sun can be directed to the azimuth. Thereby, the 2nd photovoltaic power generation panel 22 does not become a shadow of the 1st photovoltaic power generation panel 21, but electric power generation is attained by any photovoltaic power generation panel.

  In Example 4, with reference to FIG. 7, a plurality of photovoltaic power generation units 100 (see FIG. 1) of Example 1 are arranged to form a row, and the photovoltaic power generation system 400 in which the row is arranged in a plurality of rows. Explain. Adjacent photovoltaic power generation units 100 form a row, and the adjacent rows are arranged at a desired separation distance 93 for accumulating winter snow. Thereby, even in an area where there is a lot of snow, the snow falling on the photovoltaic power generation unit 100 slides down between the neighboring photovoltaic power generation unit 100 on the side where the sunlight hits, and the photovoltaic power generation unit 100 The solar power generation system having a high power generation capability can be obtained by arranging the solar power generation unit 100 by effectively using the land without leaving the snow on the top.

  In Example 5, the photovoltaic power generation unit 200 (see FIG. 5) of Example 2 is aligned with the inclined surface of the first photovoltaic power generation panel 21 with reference to FIG. The photovoltaic power generation system 500 in which a line is formed and a plurality of the lines are arranged will be described. Adjacent photovoltaic power generation units 200 are arranged with a desired separation distance 93 for accumulating winter snow accumulation.

  In the photovoltaic power generation unit 200, the second photovoltaic power generation panel 22 is provided along the side surface of the transport container unit 10 whose face piece does not receive direct sunlight 90 of sunlight. A separation distance 93 is ensured between adjacent transport container units 10. Thereby, even in an area where there is a lot of snow, the snow that has fallen on the photovoltaic power generation unit 200 slides down with the photovoltaic power generation unit 200 on the side where the sunlight hits, and is on the photovoltaic power generation unit 200. It is not left in a snowy state. Furthermore, with the electric power generated by the second photovoltaic power generation panel 22, the snow of the first power generation panel 20 is heated and slipped down to maintain the power generation of the first power generation panel 20, thereby achieving high power generation capacity. The solar power generation system 500 can be provided.

  In Example 6, with reference to FIG. 9, the plurality of photovoltaic power generation units 300 (see FIG. 6) of Example 3 are arranged so as to align the inclined surfaces of the first photovoltaic power generation panel 21, and a row is formed. A photovoltaic power generation system 600 in which a plurality of the columns are arranged will be described. In the sixth embodiment, the photovoltaic power generation units 300 are arranged at a desired distance for accumulating winter snow accumulation 92. In the photovoltaic power generation unit 300, the second photovoltaic power generation panel 22 is pivotally supported by the shaft body 71 along the roof side ridge side 12 of the transport container unit 10, fixed to the housing 25, and slid upward. The second photovoltaic power generation panel 22 is slidable in the vertical direction and the inclination angle can be changed.

  As in the fifth embodiment, in a state where snow is piled up, the snow slides into the snow accumulation space where the separation distance 93 of the photovoltaic power generation unit 300 is separated, and the indirect light 91 from the snow 92 is obtained. To generate electricity. In addition to the action of the photovoltaic power generation system of the fifth embodiment, the second photovoltaic power generation panel 22 is prevented from being buried in the snow cover 92 by sliding the second photovoltaic power generation panel 22 upward. On the other hand, in a season when there is no risk of snow accumulation, the amount of power generation can be increased by rotating the second solar power generation panel 22 in a direction in which the direct sunlight 90 of the sun can be taken.

  Further, the second solar power generation panel 22 is tilted toward the second solar power generation panel in a direction in which the direct sunlight 90 of the solar light can be collected in a state where the second solar power generation panel 22 is slid upward. It is possible to make a photovoltaic power generation system capable of generating power with both the first and second photovoltaic power generation panels so that the photovoltaic power generation panel 22 does not become a shadow of the first photovoltaic power generation panel 21. . Further, similarly to the solar power generation system 500 of the fifth embodiment, the first solar power generation panel 22 is heated with the power generated by the second solar power generation panel 22 and the snow of the first solar power generation panel is slid down to cause the first sun Of course, the power generation of the photovoltaic panel can be maintained.
