Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mount for a solar cell module such as a solar power generation system and a solar cell power supply device. More specifically, the present invention relates to a pedestal for a solar cell module that can reduce the installation cost of a solar power generation system and the like and can alleviate the restrictions on the installation site of the solar power generation system and the like.

[0002]

2. Description of the Related Art In a solar power generation system, a solar battery power supply device, etc., it is necessary to install a large number of large and medium solar battery modules facing the sun. These solar cell modules are placed and installed on a solar cell module mount. Conventional solar cell module mounts 101, 10
As shown in FIGS. 8 and 9, 6 denotes columns 102, 107 and beams 103 made of so-called angle steel, channel steel, H-shaped steel, etc.
It is configured by combining a large number of 108 and the like. This solar cell module mount (hereinafter, appropriately abbreviated as mount) 10
1, 106 are foundation parts 10 that have been pre-installed on the installation site.
It is built on 4,110. The solar cell module 105 is mounted and fixed on the mounts 101 and 106. Therefore, the mounts 101 and 106 are assembled so as to form a frame having substantially the same size as or larger than the solar cell module 105, and are relatively large structures.

[0003]

However, the conventional solar cell module mounts 101 and 106 have the following various problems. That is, in a solar power generation system or a solar cell power supply device, it is necessary to install a large number of solar cell modules 105 in the direction that most efficiently receives the sunlight, and when installing these solar cell modules 105, The accuracy of the installation angle is strictly required. That is, when installing the solar cell module 105 such as a solar power generation system, more accurate installation angle is required than when installing a small solar cell panel that serves as a power source such as a lighting type road information board. To be done. Therefore,
When installing a solar cell module such as a solar power generation system, it is necessary to design the pedestal in consideration of latitude, topography, ground, environmental conditions, meteorological conditions such as the amount of snow, etc. of the installation site. That is, the shapes and dimensions of the gantry 101 and 106 are different for each installation site. For this reason, it is difficult to standardize the gantry 101, 106, mass production in the factory cannot be performed, and the manufacturing cost of the gantry 101, 106 increases.

Further, since the conventional mounts 101 and 106 are constructed by combining a large number of columns 102 and 107 and beams 103 and 108, a large number of constituent members are required. In particular, when installing the solar cell module 105 on a flat site such as the pedestal 106 in FIG. 9, it is necessary to tilt the solar cell module 105 to the optimum angle.
The number of members such as the columns 102 and 107 and the beams 103 and 108 that make up 06 is increased. Therefore, the gantry 101, 10
6 becomes expensive.

Further, since the conventional mounts 101 and 106 are relatively large structures, the foundation work to be performed in advance becomes large-scale. In particular, when the installation site is inclined, it is necessary to reinforce the slope with a concrete layer, a concrete block or the like in order to prevent collapse caused by soil creep or the like. In addition to this, in the snowy region, it is necessary to strengthen the foundation in consideration of the influence of the snowfall on the slope, for example, the snow pressure of the glide. Even when the installation site is flat, it is necessary to cover the installation site with a concrete layer or a concrete block over a wide area to prevent the growth of weeds and prevent the solar cell module from being hidden behind the weeds. is there. Therefore, a large amount of cost is required for the foundation work for installing the solar cell module 105.

Further, as the number of constituent members of the gantry 101, 106 is large, it takes time and effort to assemble the gantry 101, 106, and the cost of this assembling work becomes high.

In addition, the construction method of the installation work of the mounts 101 and 106 is often different due to the different topography of the installation site,
This makes the installation work more expensive.

On the other hand, in the conventional mounts 101 and 106, there are many restrictions on the site where the solar cell module 105 can be installed. In other words, the riverbed and the land around the lake have no buildings or plants that block sunlight, and are convenient for installing the solar cell module 105 in terms of efficient use of sunlight. However, there is a risk that the solar cell module 105 will be flooded when the river or lake water increases, and this will destroy the electrical insulation of the solar cell module 105 and cause a failure. Was difficult to install on the land. Further, since the conventional pedestals 101 and 106 are relatively large structures, it is difficult to install them on the soft ground because large-scale foundation work is required. Furthermore, in the conventional mounts 101 and 106, when the solar cell module 105 is installed on an inclined surface facing in a direction other than the south, it is difficult to install the solar cell module 105 in the south direction, and the road slope or In a narrow place, the solar cell module 105
There will be a limited number of locations where the can be installed facing south.

Further, in the conventional mounts 101 and 106,
Since many pillars 102, 107 and beams 103, 108 are assembled, it is difficult to effectively use the land under the gantry 101, 106. For example, a solar cell module is used in a meadow or farmland. When installing 105, the land under the solar cell module 105 cannot be used as a meadow or farmland. In addition, the size of the solar cell module 105 that can be installed depends on the mounts 101, 106
The size of the base 101, 106 is larger than the open area for the installation site.
Therefore, the solar cell module 105 cannot be installed using the upper space in a range other than the open area as the installation site.

The present invention has been made to solve the above-mentioned problems. It is possible to standardize the pedestal and mass-produce it in the factory. Moreover, the installation work of the solar cell module is easy, and its installation place is easy. It is an object of the present invention to provide a pedestal for a solar cell module in which the restriction of 1 is relaxed.

[0011]

In order to achieve the above object, according to the present invention, a pedestal for a solar cell module, in which the solar cell module is installed toward the sun, is provided with a support for supporting the solar cell module at its upper end. It is characterized by.

In this case, it is desirable to support the solar cell module with one column. Further, it is desirable to divide the support column into a plurality of pieces in the length direction and to relatively connect the support columns to each other at an arbitrary angle in the circumferential direction.

Further, it is desirable that the support column is divided into a plurality of pieces in the lengthwise direction and that the support columns are connected by an arbitrary number.

Further, it is desirable that the upper end of the column and the solar cell module be connected to each other via a horizontal axis so that the angle can be adjusted.

[0015]

Therefore, in the mount for the solar cell module of the present invention, the solar cell module is installed toward the sun by mounting the pillar on the installation site and then mounting the solar cell module on the upper end thereof. This pedestal supports the solar cell module by supporting columns, and does not include many members such as beams. Therefore, the structure of the gantry becomes simple, and standardization of the gantry becomes easy. Also, the pillars will be built on the installation site without major foundation work.

Particularly, in the solar cell module mount according to the second aspect, one pillar supports the solar cell module. Therefore, the structure of this gantry becomes much simpler. Further, when the support pillar is built on the installation site, the solar cell module is installed in an arbitrary direction by adjusting the circumferential direction of the support pillar.

The solar cell module mount according to a third aspect of the invention is characterized in that the divided columns are relatively rotated and connected to each other at an arbitrary angle in the circumferential direction. Therefore, it is possible to connect the upper strut to the upper end after the lower strut is built on the installation site in advance, and even in this case, the upper strut is relatively rotated to an arbitrary angle. As a result, the solar cell module is installed in any direction.

Further, in the solar cell module mount according to the fourth aspect, the installation height of the solar cell module is adjusted by selecting the number of columns to be connected.

Furthermore, in the solar cell module mount according to the fifth aspect, when the solar cell module is rotated about the horizontal axis with respect to the upper ends of the columns, the vertical angle of the solar cell module is adjusted.

[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of the present invention will be described in detail below with reference to the embodiments shown in the drawings.

1 and 2 show an embodiment of a solar cell module mount to which the present invention is applied. This solar battery module mount (hereinafter, abbreviated as a mount) 1 is a relatively large sun. It supports the battery module 2. This solar cell module 2 has, for example, a length of 3000 mm,
The width is set to 3680 mm, and a large number of solar cell units 3 are arranged on the surface thereof.

The gantry 1 is composed of one column 4, a support rod 5, and the like. The pillar 4 has, for example, a cylindrical shape. The pillar 4 is provided with a concrete base portion 6. The base portion 6 has a cylindrical shape surrounding the support column 4 and is provided at a position near the lower end of the support column 4. The base portion 6 is formed in advance in the factory when the gantry 1 is manufactured. The base portion 6 is set to an appropriate size according to the weight of the solar cell module 2 and the like, and is formed at an appropriate position of the support column 4.

The upper end of the column 4 is connected to the back surface of the solar cell module 2 via a rotating mechanism 7. Rotation mechanism 7
The solar cell side bracket 8 and the column side bracket 9 are connected by a shaft 10 which is a horizontal axis. The solar cell side bracket 8 is fixed to the back surface of the solar cell module 2, and one semi-circular plate 8a is formed in the center thereof along the vertical direction. A hole is provided in the approximate center of the semicircular plate 8a. On the other hand, the column bracket 9 is fixed to the upper end surface of the column 4, and two side plates 9a, 9a are formed. Each side plate 9a is a solar cell side bracket 8
Are arranged on both sides of the semicircular plate 8a. Holes facing the holes of the semi-circular plate 8a are provided at approximately the center of each side plate 9a. The shaft 1 is placed in the holes of each of the plates 8a and 9a.
0 is inserted. Therefore, the solar cell side bracket 8 and the column side bracket 9 can rotate around the shaft 10.

In addition, at a substantially central position in the length direction of the support column 4,
The bracket 11 is fixed by means such as brazing. The bracket 11 has a pair of side walls 11a, and each side wall 11a is provided with a plurality of holes 11b along the length direction of the support column 4. The holes 11b are provided at predetermined intervals.

The support rod 5 has a substantially V shape. Each upper end of the support rod 5 is connected to the back surface of the solar cell module 2 via a bracket 13. More specifically, each bracket 13 is fixed to the back surface of the solar cell module 2, and one semi-circular plate 13a is formed at the center thereof, like the solar cell side bracket 8. on the other hand,
A groove is formed at each upper end of the supporting rod 5. By inserting the semi-circular plate 13a of the bracket 13 into this groove, and by further penetrating the shaft 16 at the portion where these overlap,
Each upper end of the support rod 5 is rotatably connected to the back surface of the solar cell module 2 about a shaft 16. That is, the solar cell module 2 is supported at each of the upper ends of the supporting rods 5 and the support columns 4 at three points.

Both ends of the shafts 10 and 16 are crushed so that they will not come off from the brackets 8, 9 and 13, respectively.

On the other hand, the lower end of the supporting rod 5 is provided with a hole penetrating in the horizontal direction. The lower end of the support rod 5 is inserted between the side walls 11a of the bracket 11, and the bolt 1 is inserted in the hole of each side wall 11a and the hole of the other end of the support rod 5.
4 has been inserted. Thereby, the lower end of the support rod 5 is
It is connected to the bracket 11. A nut 15 is screwed into the tip of the bolt 14 to prevent the nut from falling off the bracket 11.

The solar cell module 2 is installed on the gantry 1 constructed as described above in the following manner.

In this gantry 1, the brackets 9 and 11 are fixed to the pillar 4 and the brackets 8 and 13 are fixed to the solar cell module 2 in advance in the manufacturing factory. Then, first, a hole is dug in a position where the support column 4 is to be built, and the lower end of the support column 4 is inserted to embed the base portion 6. in this case,
Adjusting the circumferential direction of the support column 4 allows the solar cell module 2 to be attached when the solar cell module 2 is attached.
For example, you can turn to the south. Then fill the hole,
Fix the column 4 to the ground. On the other hand, in parallel with this, each upper end of the supporting rod 5 is connected to the back surface of the solar cell module 2 via each bracket 13.

Next, the solar cell module 2 is mounted on the frame 1.
Put. That is, the solar cell module 2 is connected to the upper end of the column 4 via the rotation mechanism 7, and the lower end of the support rod 5 is connected to the bracket 11. When the lower end of the supporting rod 5 is connected to the bracket 11, the lower end of the supporting rod 5 is moved in the vertical direction by selecting one of the holes of the bracket 11 into which the bolt 14 is inserted. The vertical inclination of the battery module 2 changes around the shaft 10 of the rotating mechanism 7.

Consider now that the installation site has a large latitude. At high latitudes, the sun travels in relatively low orbits. In this case, of the holes of the bracket 11,
Select the top one hole. As a result, the lower end of the supporting rod 5 is biased upward, and the upper ends of the supporting rod 5 push up the solar cell module 2. Therefore, the inclination angle of the solar cell module 2 is increased, and the sun rays can be efficiently captured. Next, consider the case where the latitude of the installation site is small. At low latitudes, the sun travels in relatively high orbits. In this case, the bracket 11
One of the holes located on the lower side is selected from among the holes. As a result, the lower end of the supporting rod 5 is biased downward, and the supporting rod 5
Each upper end of supports the solar cell module 2 in a low position. Therefore, the inclination angle of the solar cell module 2 becomes small, and the sun rays can be efficiently captured.
In this way, by changing the hole of the bracket 11 into which the bolt 14 is inserted, the vertical tilt of the solar cell module 2 can be easily changed. Therefore, the vertical tilt of the solar cell module 2 may be adjusted according to the season or the like.

Further, in this gantry 1, the support columns 4 are attached to the foundation portions 6
It will be built on the ground just by embedding it in the hole. For this reason, the large-scale foundation work required for the conventional pedestals 101 and 106 becomes unnecessary, and the pillar 4 embedded in the hole
By properly setting the length of the base and the size of the foundation 6, it is possible to build the support column 4 on soft ground, etc. Also, as shown by the chain double-dashed line in Fig. 1, the slope of the road slope, etc. It can also be built on the surface.

Furthermore, the land area on which the pillars 4 are built is small with respect to the size of the solar cell module 2.
Therefore, the space or land under the solar cell module 2 can be effectively used for other purposes, for example, as a parking lot, a meadow, or a farmland. Further, even if there is only a small amount of land as an installation site, if this site has an area large enough to build the columns 4, an obstacle such as a fence is provided in this installation site. However, the solar cell module 2 can be installed above this obstacle.

In the solar power generation system and the solar battery power supply device, it is necessary to install a large number of solar battery modules 2 side by side, but in this case, the solar battery modules 2 installed next to each other are connected. Thereby, the installation strength of the solar cell module 2 is improved.

Next, a second embodiment of the mount for a solar cell module to which the present invention is applied will be described with reference to FIG. In addition, in the following description, the gantry 1 of FIGS.
The same members as the members constituting the same are designated by the same reference numerals and the description thereof will be omitted.

The column of the pedestal 21 is divided into two in the length direction. Connection flanges 22a and 23a are formed at the connecting portions of the columns 22 and 23, that is, at the upper end of the lower column 22 and the lower end of the upper column 23, respectively. Each flange 22a, 23a is provided with a plurality of bolt holes along the circumferential direction. The columns 22 and 23 are connected by tightening the flanges 22a and 23a with bolts and nuts.

When installing this pedestal 21, first, the lower part of the lower support 22 is embedded and fixed in the hole of the installation site, and then the upper support 23 is connected to the lower support 22. Each prop 2
When 2, 2 are connected, the upper support 23 is rotated in the circumferential direction with respect to the lower support 22, and the upper support 23 is set in a desired orientation. That is, although each of the flanges 22a and 23a is provided with a plurality of bolt holes in the circumferential direction, the upper support column 23 is relatively rotated in the circumferential direction to an arbitrary angle while the opposing bolt holes are displaced in the circumferential direction. After setting the column 23 in a desired orientation, the flanges 22a and 23a are fastened with bolts and nuts. Therefore, the lower support 22
Can be built on the ground, and the upper column 23 can be connected later. Even in this case, the solar cell module 2 can be installed in a desired direction.

Further, as shown in FIG. 4, the height of the gantry 31 can be increased by increasing the number of columns to be connected. That is, the height of the gantry 31 can be adjusted by increasing or decreasing the number of columns 32 to 34 to be connected, and the solar cell module 2 can be installed at a desired height. Therefore, even when weeds grow around the columns 23 to 34,
The solar cell module 2 can be easily installed higher than the weeds. Along with this, it is not necessary to cover the installation site with a concrete layer or the like to prevent the growth of weeds.
Further, even when the solar cell module 2 is installed in a place where there is a risk of water infiltration such as a riverbed or the vicinity of lake water, it becomes easy to set the installation height to a sufficient height.

Although FIG. 4 shows a case where three columns 32 to 34 are connected, it goes without saying that four or more columns may be connected.

Next, a third embodiment of the solar cell module mount to which the present invention is applied will be described with reference to FIG. This gantry 41 is configured by including two stanchions 4 similar to the stanchions 4 of the gantry 1 in FIGS. 1 and 2. Each prop 4
Are standing a predetermined distance apart. The upper ends of the columns 4 are connected to the back surface of the solar cell module 2 via a rotating mechanism 7. In addition, a bracket 11 is attached to each of the columns 4.
Is stuck.

Unlike the support rod 5 of the gantry 1, the support rod 42 of the gantry 41 is formed in a straight shape without branching. The upper end of the support rod 42 is connected to the back surface of the solar cell module 2 via the bracket 13. Also,
The lower end of the support rod 42 is connected to the bracket 11 via a bolt.

When the solar cell module 2 is installed using this pedestal 41, first, the base portion 6 having two holes is formed on the installation site. Then, the lower portions of the columns 4 are inserted into the holes of the base 6 and fixed with concrete or the like. On the other hand, in parallel with this, the upper end of each support rod 42 is connected to the back surface of the solar cell module 2 via each bracket 13. Then, the upper ends of the columns 4 are attached to the rotating mechanism 7
The lower end of each support rod 42 is connected to each bracket 11 while being connected to the back surface of the solar cell module 2 via. As a result, the solar cell module 2 is supported and installed by the columns 4. Even in this case, the vertical tilt of the solar cell module 2 can be adjusted by changing one of the plurality of holes of the bracket 11 that connects the lower end of the support rod 42 via a bolt. .

In the frame 41 of this embodiment, 2
Although the solar cell module 2 is supported by the four columns 4, the number of the columns 4 is not limited to two, and the solar cell module 2 may be supported by three or more columns 4.

Further, a fourth embodiment of the gantry to which the present invention is applied will be described with reference to FIG. This pedestal 51 is provided with an arc-shaped plate 52 in place of the support rod 5 constituting the pedestal 1 and a bracket 53 in place of the bracket 11. That is, the bracket 53 fixed to the support column 4 is provided with the hole 53a as shown in FIG. A weld nut 54 is provided inside the bracket 53 so as to face the hole 53a.

The arc-shaped plate 52 is arranged so as to overlap the bracket 53, and both ends thereof are fixed to the back surface of the solar cell module 2. At a predetermined position of this arc-shaped plate 52,
A plurality of holes 52a are provided along the length direction. One of the holes 52a is selected and the bolt 55 is inserted. That is, the bolt 55 is inserted into the selected hole 52 a and the hole 53 a of the bracket 53 and screwed into the weld nut 54. This allows
The arc-shaped plate 52 is connected to the bracket 53, and the solar cell module 2 is fixed. When the hole 52a into which the bolt 55 is inserted is changed to another hole 52a, the vertical inclination of the solar cell module 2 changes.

The above-described embodiment is an example of the preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications can be made without departing from the gist of the present invention.

For example, each of the mounts 1, 21, 31, 4 described above
1 and 51, the support column 4 and the solar cell module 2 are connected via the rotation mechanism 7, and the shaft 10 arranged horizontally is used.
Although the configuration in which the vertical tilt of the solar cell module 2 is adjusted around the center is not limited to this, for example, the pillar 4 and the solar cell module 2 may be connected via a ball joint. In this case, the solar cell module 2 can be tilted around the ball of the ball joint, and therefore, it is not necessary to consider the circumferential direction of the pillar 4 when the pillar 4 is erected.

The rotating mechanism 7 is not always necessary, and the solar cell module 2 may be fixed to the upper ends of the columns 4. In this case, it is impossible to change the vertical inclination of the solar cell module 2 with respect to the support column 4, so the support column 4 is built diagonally, and at this time, the inclination angle is set appropriately so that the solar cell module is It is desirable to adjust the vertical inclination of 2.

[0049]

As described above, the mount for a solar cell module according to the present invention is provided with the support column for supporting the solar cell module at the upper end. Therefore, the structure of the gantry becomes simple, and it is not necessary to change the design of the gantry for each site to be installed. For this reason, since the gantry can be standardized, mass production in a factory becomes possible, and the gantry manufacturing cost can be reduced. In addition, since the structure of the gantry is simple, it is not necessary to perform a large-scale foundation work when installing the solar cell module, and the gantry itself can be easily assembled. Therefore, the installation work of the solar cell module is simplified and the construction cost is greatly reduced. Furthermore, since large-scale foundation work is not required, it is possible to install the solar cell module even on soft ground or in flooded areas.

In particular, in the mount for a solar cell module according to claim 2, since the solar cell module is supported by one pillar, the structure becomes simpler, and when the pillar is built, the circumference thereof is reduced. The direction of the solar cell module can be adjusted by changing the direction.
