Description

  The present invention relates to a power generation system using a large number of solar panels, and in particular, power generation capable of adjusting the angle according to the season of a gantry supporting a large number of solar panels and ensuring the strength against strong winds. It is about the system.

  Various power generation systems that use a large number of solar panels have been proposed, but avoiding restrictions due to being installed in open ground, pursuing further cost performance, and angle according to the season Various ideas have been made to make adjustments possible.

  In making these ideas, it is necessary to consider which items are important, but in recent years, as in recent years, when it is time to make effective use of idle land, this type of power generation system using solar panels is used. Has become larger. Then, how to reduce the installation cost while satisfying the minimum installation conditions is also important.

  In addition, it is well known that each solar panel can perform optimal power conversion by allowing sunlight to be incident on the panel in an orthogonal state. Then, it is necessary to always take into account the daily and seasonal changes in solar altitude.

  Furthermore, in this type of power generation system, in order to effectively receive sunlight, which is a parallel light beam, with a solar panel, a large number of solar panels must be installed on the ground as a flat surface. Not only is it easy to be exposed to rain and snow, but it must be subject to wind pressure because it is usually installed at an angle to the ground.

  From the above, as a number of conventional technologies, see “Solar power generation panel mount” proposed in Patent Document 1 and “Variable angle solar power panel mount” proposed in Patent Document 2. However, further consideration will be given to the advantages and disadvantages of the conventional photovoltaic power generation system.

JP-A-2006-116264, abstract, FIG. 1 and FIG. Utility Model Registration No. 3207547, FIG.

As described in Paragraph 0006 of Patent Document 1, the “solar power generation panel mount” proposed in Patent Document 1 is “a photovoltaic power panel having a structure in which the panel structure is supported by a single column. As a gantry, the support strength of the panel structure and the overall strength of the gantry are large, and even a large panel structure with a wide light receiving area exhibits excellent durability against sufficient wind pressure and earthquake shaking in strong winds. 9 and 10 of the present application, as shown in FIG. 9 and FIG. 10 of the present application, “a plurality of vertical beam members 11 along the front-rear inclination direction and a plurality of horizontal bars along the horizontal horizontal direction”. A crosspiece 12 is connected to each crossing position to form a grid-like panel receiving frame 1, and the panel receiving frame 1 is supported by a single column 2 made of a rectangular hollow aluminum mold at the center. Along with the base side of the support column 2 and the panel Only between each plurality of places around the frame 1, the support stay 3 upper connecting fitting 4A consisting of a hollow aluminum shape member of each plurality of longitudinal, 4B and lower connecting fitting 5A, 5B
And a plurality of photovoltaic power generation panels P are planarly mounted on the panel receiving frame 1 ”.

Then, in the "solar power generation panel mount" proposed in Patent Document 1, as described in Paragraph 0015 of Patent Document 1,
・ Because the grid-like panel receiving frame 1 is supported by a single column 2 at the center, it can be constructed efficiently and at low cost, and it is less affected by land subsidence after construction. There is no fear of causing distortion, breakage, tilting, rattling, etc. ・ The panel receiving frame 1 is supported at a plurality of front and rear positions by a plurality of front and rear support stays 3 installed between the support frame 2 and the base side. Therefore, the support strength of the panel structure 10 is large, and the strength of the entire gantry is also large, and it is possible to exhibit excellent durability against the wind pressure in strong winds and the shaking of the earthquake.

  However, in the “photovoltaic power generation panel mount” proposed in Patent Document 1, the panel receiving frame 1 includes a plurality of front and rear support stays 3 that are installed between the support frame 3 and the base side of the column 2. The angle of the panel receiving frame 1 itself cannot be changed because it is also supported at the location.

  In order to change the angle of the “photovoltaic power panel base”, as proposed in Patent Document 2, “the tilt angle variable portion 4 of the variable angle solar power panel base 1 is connected to the panel. In the angle adjusting plate 41, the angle adjusting plate 41 is suspended along the support column 2 from the position where the mounting portion 3 is pivotally supported and is attached to the panel mounting portion 3 so as to be rotatable integrally therewith. A plurality of angle adjustment holes 42 formed along an arc centering on the rotation axis of the panel mounting portion 3, and any one of these angle adjustment holes 42 and the column portion 2 are connected to each other. It is considered that it should be “fixed” (summary, see FIG. 11 of the present application).

  However, the angle adjustment technique of Patent Document 2 is disclosed in Patent Document 1 as “Panel receiving frame 1 is supported at a plurality of front and rear positions by a plurality of front and rear support stays 3 laid between the base side of column 2. Of course, it cannot be applied to the “Yes” technology. This is because the technique of Patent Document 1 tries to fix the panel receiving frame 1 without tilting it.

  On the other hand, considering solar panels that have been mass-produced in recent years, the physical use of “hard but fragile” is because they basically use large amounts of “silicon substrates” and “glass”. Many have properties. Here, if the platform supporting such a solar panel repeatedly vibrates or bends due to irregular winds, micro cracks may enter the silicon substrate and glass plate that make up the panel, The conductor on the silicon substrate may be disconnected, making it impossible to generate power.

  Therefore, if it is assumed that the gantry is sturdy and the solar panel is to be prevented from being damaged for a long period of time, as proposed in Patent Document 1, the number of members is increased to increase the rigidity, or the gantry itself is made of steel. It is necessary to secure rigidity that is not affected by wind by using or using concrete or concrete. If such materials and configurations are adopted, it goes without saying that the cost of the entire system is unavoidable.

  Therefore, the present inventors conducted various studies on how to make a solar power generation system that can be installed at low cost, can adjust the angle according to seasonal changes, and can withstand wind power sufficiently. As a result of overlapping, the present invention has been completed.

That is, the object of the present invention is to
(1) Simplify the overall structure as much as possible (2) Easy installation and angle adjustment work (3) Temporarily, it is possible to easily make it into a form that can safely pass the typhoon that hits (4) Damage (5) The installation work can be performed at low cost, so that the vibrations caused by the changing wind force can be suppressed on the structure rather than the material. An object of the present invention is to provide a photovoltaic power generation system that can adjust the angle according to changes and can sufficiently withstand wind power.

In order to solve the above problems, the means taken by the present invention will be described with reference numerals used in the description of the best mode to be described later.
“A power generation system using a large number of solar panels 20,
A plurality of vertical beam members 11 and horizontal beam members 12 combined in a lattice shape, and a gantry 10 having a front surface and a back surface,
A large number of solar panels 20 assembled on the surface side of the frame;
One support column 30 supported at the upper end so that the gantry 10 can tilt in the vertical direction at the center of the back surface side of the gantry 10;
Each distal end is fixed to the upper two places of the gantry 10, each inner end is connected to one first connection point 43a, and two development wires 41a of the same length are connected to the first connection point 43a. A first wire group 40A composed of a single winding wire 42a wound around a first winding portion 32a attached at a lower end near the lower end of the column 30;
Each distal end is fixed to the lower two places of the gantry 10, each inner end is connected to one second connection point 43b, two development wires 41b of the same length, and the inner end is connected to the second connection point 43b. A second wire group 40B composed of a single winding wire 42b that is coupled and is wound around a second winding portion 32b attached at the lower end of the column 30 in the vicinity of the lower end;
The fixing portions of the development wires 41a and 41b and the winding wires 42a and 42b constituting the first and second wire groups 40A and 40B with respect to the gantry 10, the connection portions with respect to the first and second connection points 43a and 43b, And except for the winding part to the first and second winding parts 32a and 32b, it is free,
A power generation system characterized in that a plurality of oblique beam members 13 are further fixed to the vertical beam member 11 and / or the horizontal beam member 12 combined in a lattice shape with respect to the gantry 10.
It is.

  In this power generation system, the upper end of one support column 30 standing at a construction site is tiltably connected to the center of the back surface of one mount 10 on which a plurality of solar panels 20 are placed on the front surface side. For example, as shown in FIG. 1, it is sufficient to connect the gantry 10 and the upper end of the support column 30 with a horizontal pin 31. The tilting direction is a vertical direction and not a horizontal direction.

  The tilt direction of the gantry 10, in other words, the tilting direction of the solar panel 20, is the vertical direction. Each solar panel 20 generates power most efficiently for 2 to 3 hours before and after the sun is located in the sky. This is because the seasonal change has a greater influence than the difference in the irradiation direction between morning and evening and noon. Also, changing the angle from Asahi to sunset, that is, tilting in the left-right direction, requires a certain amount of equipment, and even if this is done, efficient or effective power generation can be achieved for the equipment cost invested. Because there is no.

  In addition, by making the tilting direction of the gantry 10 only in the vertical direction, the gantry 10 can be easily supported by the single support column 30, for example, as in the technique proposed in Patent Document 1 In addition, since it is not necessary to use a plurality of support columns, it will greatly help to reduce the installation cost.

  If the gantry 10 can be tilted with respect to the upper end of the support column 30, the tilting of the gantry 10 must be fixed by preventing the tilting. The first wire group 40 </ b> A and the second wire group are responsible for this. 40B. In order to fix the tilt angle of the gantry 10 with the first wire group 40A and the second wire group 40B, first, the first wire group 40A and the second wire group 40B that have been fixed at the previous tilt positions are used. Each fixed state in the 1st winding part 32a and the 2nd winding part 32b is cancelled | released, and the inclination angle adjustment of the mount frame 10 is performed. Since the configurations and functions of the first wire group 40A and the second wire group 40B are substantially the same, the following description will focus on operations and functions on the first wire group 40A side.

  For example, when the inclination angle of the gantry 10 is in the state shown in FIG. 7 and is changed to the state shown in FIG. 8, the winding amount of the winding wire 42b is adjusted by operating the second winding portion 32b on the right side of the drawing. If increased, the winding wire 42a is rewound from the first winding portion 32a on the first wire group 40A side, and the inclination angle of the gantry 10 is changed. In this case, the two development wires 41a having the same length connected to the gantry 10 side are connected to the first connection point 43a at the upper end of one winding wire 42a. As shown in FIG.1 and FIG.2, it will be rewound upward from the 1st winding part 32a. On the other hand, on the opposite side of the gantry 10, the winding wire 42b of the second wire group 40B is wound downward by the second winding portion 32b, and the lower part of the gantry 10 moves downward. If the gantry 10 is at a predetermined angle, the back surface of the gantry 10 is “five-point supported” if the first winding portion 32a and the second winding portion 32b are wound and returned and fixed. Become.

Among the above, when the first wire group 40A and the second wire group 40B, which are important structures of the present invention, are considered, the following points emerge.
In each of the first wire group 40A and the second wire group 40B, the winding wires 42a and 42b are the same length, and the first connection point 43a and the second connection point 43b at the lower ends of the two development wires 41a and 41b. Are wound around the first winding portion 32a and the second winding portion 32b that are installed in the immediate vicinity of the support column 30, so that these winding wires 42a and 42b are connected to the support column 30. And move only up and down at approximately the same position.
This means that the first wire group 40A and the second wire group 40B receive the force (pressing force and twisting force) received from the gantry 10 in the vicinity of the lower end of the support column 30 and cause the gantry 10 to shake. Suppresses the generation of force.
-If the generation of the force that causes the gantry 10 to be shaken can be surely suppressed, the vibration of the gantry 10 due to the changing wind force can be suppressed. No cracks are generated in the substrate, the conductor on it, or the glass.
In addition, each of the first wire group 40A and the second wire group 40B is configured by connecting three wires at the first connection point 43a or the second connection point 43b, so that a part of the wire is temporarily provided. Even if it is damaged, it is sufficient to replace only that part, which helps to reduce the cost of the entire system.
Since each of the first wire group 40A and the second wire group 40B is made of a flexible material called “wire”, both the handling and installation (connection) of the first winding group 32a and the second winding group are performed. Winding around the take-up portion 32b can be performed without difficulty, and the workability is very excellent as compared with a rigid support as proposed in Patent Document 1 and the like.

In the power generation system according to the present invention, as described above, the angle of the gantry 10 can be easily changed according to the season, so that the summer state shown in FIG. 7 is changed to the winter state shown in FIG. Can be easily changed and adjusted during that time, and can be easily changed to the typhoon passing state shown in FIGS. In the typhoon passing state shown in FIG. 2 and FIG. 3, the angle of the gantry 10 is adjusted so as to be substantially horizontal. Since only the surface of each solar panel 20 constituting the power generation system flows away, there is no action of force by wind force in each part, and damage and deformation do not occur.

Therefore, in the power generation system according to claim 1, as described above,
(1) The overall structure has been simplified (2) Installation work and angle adjustment work can be easily performed (3) The typhoon that has come in can be used safely (4) Replacement of damaged parts (5) The vibration caused by the changing wind force can be suppressed, but it can be realized, the installation work can be done at low cost, the angle can be adjusted according to the seasonal change, and it can withstand wind force well. -ing

  Further, in the power generation system of the present invention, it is the horizontal pin 31 that supports the gantry 10 so that it can be tilted in the vertical direction at the upper end of one column 30.

  The inventors of the present invention fully understand that it is effective in increasing the power generation efficiency to receive sunlight rays in a state orthogonal to the surface of each solar panel 20. A system that constantly tracks the sun must be prepared. Since this tracking system is naturally very expensive, the inventors have ignored the “time change” at all and have focused on only the “seasonal change” to make the present invention. In order to cope with this seasonal change, it has been described above that a technique as proposed in Patent Document 2 already exists.

  In this power generation system, it is only necessary to allow the horizontal pin 31 to be tilted only in the vertical direction of the gantry 10 with respect to the support column 30, and fixing at the intended tilting position is performed by the first wire group 40A. And it is sufficient if it is performed on the second wire group 40B side. In other words, in the technique of Patent Document 2, for example, both are fixed at the upper end of the support column 30 of the gantry 10, and then the force when the gantry 10 receives wind is concentrated on the upper end of the support column 30. Therefore, it is difficult to fix the tilt, but the power generation system according to claim 2 does not cause such a problem at all.

  The horizontal pin 31 can be “one” as shown in FIG. 4, and if the axes are at the same position as shown in FIG. "Two things" may be adopted.

  Therefore, in this power generation system, the same function as described above is exhibited, and tilting and fixing with respect to the upper end of the column 30 of the gantry 10 is very simple.

In order to solve the above-mentioned problem, the means taken by the invention according to claim 3 is described in claim 1 or claim 2. And, for this power generation system, the lower part of the support column 30 is fixedly supported. A block 50 is further provided.

  This power generation system is provided on the condition that a fixing block 50 that fixedly supports the lower portion of the support column 30 is further provided.

  In the power generation system according to the present invention, the gantry 10 for supporting the oblique beam members 13 assembled on the surface side is supported so as to be tiltable in the vertical direction at the upper end of one column 30. However, there is no problem if it is hard enough to fix the support 30 firmly, but if it is a soft part such as an idle farmland, some means must be taken to fix the support 30.

  It is the fixed block 50 described in the power generation system that is used when the installation location is such soft ground. In the power generation system according to the present invention, since the gantry 10 is tiltably connected to the upper end of one column 30 in the first place, it is sufficient that the portion where the column 30 is to be installed is hard. The entire lower surface need not be rigid. It is the fixed block 50 that secures the minimum required hard installation location.

  Since the fixed block 50 is the minimum necessary, even if the other land is soft, there is no influence on the fixing of the support 30. In other words, since there is no need to harden the entire surface of the idle farmland, construction costs can be saved and the construction period can be shortened.

  Therefore, this power generation system can perform the same function as described above, and can complete the minimum necessary hardening allowance with only the fixed block 50 when installed on soft ground.

As described above, in the present invention,

It is a rear view of the system shown by patent documents 1. It is a perspective view of the system shown by patent document 2. FIG.

  Next, the invention according to each claim configured as described above will be described with reference to the power generation system according to the embodiment shown in the drawings. FIG. 1 shows a substantially entire configuration of the power generation system according to the present embodiment. It is. FIG. 1 shows a rear view when the gantry 10 supporting a plurality of solar panels 20 (indicated by phantom lines) is set up substantially vertically, and includes a support 30, a first wire group 40 </ b> A, All of the two-wire group 40B and the fixed block 50 are shown including their relationship.

  The gantry 10 includes a plurality of vertical crosspieces 11 and horizontal crosspieces 12 combined in a lattice shape, a front side surface (upper side surface shown in FIG. 2) on which a plurality of solar panels 20 are mounted, a support column 30 and a first wire. A back side surface (a side surface shown in FIG. 1) to which the group 40A and the second wire group 40B are connected is provided. In the gantry 10 of the present embodiment, as shown in FIG. 1, a plurality of oblique beam members 13 fixed to the vertical beam members 11 and the horizontal beam members 12 are employed. These vertical crosspieces 11, horizontal crosspieces 12 and slanting crosspieces 13 have so-called C-channel shapes in order to reduce the weight while ensuring rigidity. Metal materials such as iron and aluminum are used. Used, for example, connected to each other at vertical and horizontal intersections.

  About each vertical crosspiece 11, the thing about 6 m in length is employ | adopted, as illustrated in FIG. 1, one pair is employ | adopted for each right and left both sides, and one pair is adopted in the center part. About the crosspiece 11, the connection location of the 1st wire group 40A and the 2nd wire group 40B which are mentioned later is ensured, and about the pair of center part, the location which fixes the bracket member for supporting the horizontal pin 31 is ensured. It is. Of course, with respect to these vertical crosspieces 11, each horizontal crosspiece 12 is fixed and supported from the surface side.

  Each crosspiece 12 is mainly used to support the upper and lower sides of each solar panel 20, and has a length of about 8 m. Further, the portions of each crosspiece 12 that do not support each solar panel 20 are separated by a predetermined interval (about 26 cm in the present embodiment) to form a gap. Can pass through some of the strong winds. The gaps formed so that the wind can pass between the horizontal bars 12 also compensate for sufficient strength of the gantry 10 against the wind.

As shown in FIG. 4, a horizontal pin 31 (to be described later) is held on the back surface of the gantry 10 constituted by the vertical beam material 11, the horizontal beam material 12, and the necessary oblique beam material 13. A bracket 14 is provided, and a bracket 33 on the side of the support column 30 connected to the bracket 14 via a horizontal pin 31 is fitted. In other words, the center of the back surface of the gantry 10 and the upper end portion of the support column 30 are connected so as to be tiltable via the horizontal pin 31, and the tilting direction is a comparison between FIGS. 3, 7, and 8. As can be seen from the above, it is the “vertical direction”.

  As described above, since the center of the rear surface of the gantry 10 and the upper end of the support column 30 are connected to each other so as to be tiltable, the solar panels 20 installed on the surface of the gantry 10 In order to oppose, it is necessary to fix between the two. The first wire group 40A and the second wire group 40B prevent the tilting of the gantry 10 with respect to the upper end of the column 30. And when the gantry 10 becomes a predetermined angle, the first winding part 32a and the second winding part 32b used to prevent the tilting are fixedly provided at the lower part of the support column 30, The first winding unit 32a and the second winding unit 32b are manually operated. Of course, it goes without saying that the first winding portion 32a and the second winding portion 32b have stoppers for preventing their rotation.

  First, the first wire group 40A is wired on the back side of the support column 30 as shown on the left side of FIGS. 3, 7 and 8 for convenience, as shown in FIGS. As described above, each of the distal ends is fixed to the upper two places of the gantry 10 and each inner end is connected to one first connection point 43a. The two development wires 41a have the same length, and the inner end is the first connection point. 43a, and the lower end is composed of a single winding wire 42a wound around a first winding portion 32a attached in the vicinity of the lower end of the support column 30. In other words, the first wire group 40A has a “Y shape” as shown in FIGS. 1 and 2 when it is completely wired.

  The second wire group 40B is wired on the front side of the support column 30 as shown on the right side of FIGS. 3, 7 and 8 for convenience, as shown in FIGS. In addition, the two ends of the developing wire 41b are fixed to the lower two places of the gantry 10 and the inner ends are connected to one second connecting point 43b, and the inner ends are the second connecting points. 43b, and the lower end is composed of one winding wire 42b wound around the second winding portion 32b attached in the vicinity of the lower end of the support column 30. In other words, the second wire group 40B is also “Y-shaped” as shown in FIGS. 1 and 2 when completely wired.

  In the power generation system of this embodiment, by adopting the horizontal pin 31, it is possible to tilt only the vertical direction of the gantry 10 with respect to the support column 30, and the fixing at the intended tilting position is the first wire group 40A. And it is sufficient if it is performed on the second wire group 40B side. In other words, in the technique of Patent Document 2, for example, both are fixed at the upper end of the support column 30 of the gantry 10, and then the force when the gantry 10 receives wind is concentrated on the upper end of the support column 30. In this power generation system, however, such a problem does not occur at all.

  By the way, the horizontal pin 31 can be tilted only in the vertical direction of the gantry 10 with respect to the support column 30, and the horizontal pin 31 is “one piece” as shown in FIG. 4, or as shown in FIG. If the minds are at the same position, “two” may be adopted.

  The first wire group 40A described above will be described in more detail. Each tip of the two development wires 41a having the same length is connected to the upper end of the back surface of the gantry 10, and each lower end is one first wire. Since the connecting wires 43a are connected to the connecting points 43a, the developing wires 41a form two equal sides of “inverted isosceles triangles” connecting the respective ends and the first connecting points 43a. The winding wire 42a extending downward from the first connection point 43a corresponds to the “Y-shaped” “vertical bar” described above. As shown in FIG. Or, when viewed from the rear, it overlaps with the support 30.

  Therefore, in this power generation system, when the lower end of the winding wire 42a constituting the first wire group 40A is wound up by the first winding portion 32a, the winding force is applied to the gantry via each deployment wire 41a. This is a force that evenly lowers the left and right symmetrical portions of the back surface 10, and the gantry 10 is pulled down without shaking left and right. The above is similarly demonstrated about the 2nd wire group 40B.

  In addition, the first wire group 40A and the second wire group 40B are configured by three wires that hardly extend and are wired before and after the support column 30, so that each first winding If the winding by the take-up portion 32a and the second take-up portion 32b is performed firmly, the gantry 10 is fixed at five points including the horizontal pins 31 on the support column 30 side. In other words, the first wire group 40 </ b> A and the second wire group 40 </ b> B prevent the rack 10 from being beaten, moved, or rocked by the wind.

  Of course, the first wire group 40A and the second wire group 40B are shown in FIG. 2 and FIG. 3 by adjusting the amount of winding in each of the first winding portion 32a and the second winding portion 32b. The angle adjustment can be easily performed in the typhoon correspondence state, the winter correspondence state shown in FIG. 7, and the summer correspondence state shown in FIG.

  By the way, if the ground of the installation location is fixed to some extent, the fixing location of the support 30 is secured with a ground improvement soil mixed with cement, and the support 30 is fixed to the ground improvement soil. The fixing flange integrated with the lower end is fixed using a ground screw or a steel pipe.

  In the case of a soft ground such as an idle land or an abandoned farmland, which is likely to be insufficient in fixing strength with the above ground improvement soil alone, a fixed block 50 as shown in FIG. 6 may be employed. The fixed block 50 is a concrete block having substantially the same shape and size as the ground improvement soil described above. A fixed flange integrated with the lower end of the support column 30 is connected to the fixed block 50 with a ground screw or a steel pipe. What is necessary is just to fix using a pipe. On the contrary, by adopting such a fixing block 50, it is possible to easily erect and fix the column 30 at any installation location under any conditions.

  In addition, although the fixed block 50 shown in FIG. 6 is a square whose planar outline is about 2 m, the thickness can be set as appropriate.
