Description

  The present invention relates to a variable angle solar panel installation stand that can easily change the inclination angle of a solar panel manually even after installation.

In recent years, attention to energy that does not emit carbon dioxide has been increasing. In particular, expectations are high for solar power generation, which is a representative example of such energy.
In solar power generation, it is extremely important to receive sunlight efficiently, and it is desirable to tilt the solar panel at an appropriate angle according to the solar altitude that changes with the season. When installing a solar panel on a flat surface such as the ground surface or the roof of a building, a dedicated stand is used to install the solar panel at a predetermined angle. Whether or not adjustment can be performed quickly, simply, and reliably depends greatly on the structure of the gantry. For this reason, many patent applications or utility model registration applications have been filed for technologies related to a stand for solar panels.

For example, in Utility Model Registration No. 3026876 (Patent Document 1), a solar panel is pivotally supported on an upper part of an inclined pedestal so as to be rotatable, and a drive mechanism is provided on the back of the solar panel. A "support panel for solar cell panel" that can be provided to change the solar panel to a desired angle is disclosed.
Utility Model Registration No. 3181778 (Patent Document 2) has a function of adjusting a tilt angle of a solar panel by configuring a column supporting a beam frame structure holding a solar panel with an H-shaped steel or a steel sheet pile. A “photovoltaic panel support frame” that connects a support column and a beam frame structure with a connecting metal fitting is disclosed.
JP 2013-185393 A (Patent Document 3) discloses a plurality of vertical members that support a solar panel from the back side, a cross member that supports the vertical member from below, and a joint that supports the cross member. It has a member, an installation leg with this joint member attached to the tip, and a connecting member that connects the cross member and the vertical member, and a recess into which the cross member fits is formed on the bottom surface of the vertical member. A “solar cell panel mounting base” is disclosed.

Utility Model Registration No. 3026876 Utility Model Registration No. 3181778 JP 2013-185393 A

The "solar cell panel support frame" described in Patent Document 1 is capable of rotating the solar panel so that the inclination of the solar panel can be changed according to the altitude of the sun. Snow can be dropped on the light panel. However, a screw jack provided with a motor is employed as a drive mechanism for rotating the solar panel. For this reason, the equipment cost is increased and the number of parts is large, so that installation at the site is troublesome.
The “photovoltaic power generation panel support frame” described in Patent Document 2 is realized by using a connection hardware that connects the support column and the beam frame structure to adjust the inclination angle of the solar panel. Therefore, the structure is simple, the assembly work is simple, and the workability is also good. However, the joint fittings that constitute the connection hardware that connects the support column and the beam frame of the solar panel are fixed by welding. In this case, after installing a stand on the ground surface and attaching a solar panel, it is not possible to easily change the inclination angle of the solar panel in accordance with the solar altitude according to the season.
The “solar cell panel mounting base” described in Patent Document 3 has a simple base structure that supports the solar panel, and the angle of the solar panel can be changed simply by changing the length of the installation leg. However, in order to change the angle of the solar panel, the length of the installation leg must be changed. That is, it is necessary to prepare an appropriate number of installation legs having different lengths in consideration of the inclination of the ground surface. Moreover, once the frame including the installation legs is installed, the inclination of the solar panel cannot be changed in accordance with the solar altitude that varies depending on the season.

  This invention makes it a subject to provide the stand for solar panel installation provided with the following characteristics in view of the problem of said existing technique. In other words, even after installation, the inclination angle of the solar panel can be easily changed according to the altitude of the sun that changes according to the season, the change can also be changed manually without using a dedicated drive mechanism, The work is extremely simple and does not require skilled skills, the structure of the gantry is simple, the number of parts is small, and the cost can be reduced.

Thus, the rotating shaft tube (pipe) and the column supporting the solar panel are fixed by pinning via the rotating bearing. Therefore, the inclination angle of the solar panel can be changed by changing the location where the pin is inserted.

  A solar panel installation stand (hereinafter also referred to as a “stand”) 1 according to an embodiment of the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the solar panel installation stand 1 has a solar panel 2 supported by a frame material from the back side. The frame material is composed of a plurality of vertical members 3. Each vertical member 3 is supported by one rotating shaft tube 4 from the lower side. The rotating shaft tube 4 is supported by support columns 5 at both ends at least. Further, the rotary shaft tube 4 and each support column 5 are connected by a rotary bearing 6. The gantry of the present invention is characterized in that the rotation angle 6 allows the inclination angle of the solar panel 2 to be changed manually even after installation. The change of the tilt angle will be described in detail later.

As shown in FIG. 2 (A), each vertical member 3 of the frame material that supports the solar panel 2 from the back side uses a metal square member or H-shaped steel, and its length is the vertical length of the solar panel 2. It is almost equal to the length. The solar panel 2 is composed of one or more solar modules.
Each vertical member 3 that supports the solar panel 2 from the back surface is fixed to a predetermined portion of the rotary shaft tube 4 with a bolt 7 at the center in the longitudinal direction. As shown in FIG. 2B, the plurality of bolt holes 41 of the rotating shaft tube 4 are arranged on a specific side line L1. Thereby, all the vertical members 3 fixed to the rotating shaft tube 4 are arrange | positioned on the same plane. Further, as shown in FIG. 2A, the vertical member 3 is securely fixed to the rotary shaft tube 4 by a fastener 8 such as a U-bolt. Moreover, since the rotating shaft tube 4 is supported in the center of the vertical member 3, that is, in the vicinity of the center of gravity, the work burden when changing the inclination angle of the solar panel is reduced.
A line segment connecting the center O of an arbitrary cross section orthogonal to the longitudinal direction of the rotating shaft tube 4 and the intersection P of the straight line L1 is referred to as a reference line, and this point P is referred to as a reference point.

  As shown in FIG. 1, the rotary shaft tube 4 is a metal round pipe that supports the longitudinal member 3 from the orthogonal direction. The rotary shaft tube 4 is stretched over the upper ends of two or more struts 5. A rotary bearing 6 connects the rotary shaft tube 4 and the column 5. At both ends of the rotary shaft tube 4, that is, at locations where the rotary shaft tube 4 is connected to the support column 5 via the rotary bearing 6, through holes 42 and 43 penetrating the rotary shaft tube 4 in the short direction are provided (see FIG. 7).

The support 5 is preferably made of H-shaped steel from the viewpoint of strength and cost. FIG. 3A shows a front view of the column 5, and FIG. 3B shows a side view.
The leg portion 51 of the support column 5 includes a base plate 51A and four ribs 51B fixed to the upper surface of the concrete base 9 provided on the ground. The support column 5 has a column portion 52 standing vertically from the leg portion 51, and a rotary bearing 6 is attached to the upper end portion 53 of the column portion 52 as described later.
The column 5 supports the rotating shaft tube 4, and the number of columns 5 is determined in consideration of the size and weight of the vertical member 3 and the solar panel 2 that the rotating shaft tube 4 supports from the back surface. Further, in order to improve the stability, an auxiliary column 10 as shown in FIG.

Next, the rotary bearing 6 will be described with reference to a plan view of FIG. 4A and a front view of FIG.
The rotary bearing 6 is composed of two bearing brackets 6A and 6B having the same shape that are cylindrical when joined face to face in the longitudinal direction. Each of the bearing fittings 6A and 6B includes a fitting main body 61 having a semicircular cross section for supporting the rotary shaft tube 4 and a tongue piece portion 62 having a total of four at each end of both sides of the main body 61. As shown in FIG. 4B, each of the bearing fittings 6A and 6B has a substantially Ω shape when viewed from the front.
The metal fitting body 61 has two through lines L2 and L3, which intersect with the longitudinal center line (not shown) of the rotary bearing 6 at one point. Reference numeral 64 is given to two through holes through which the through wire L2 penetrates the bearing fitting 6A and the bearing fitting 6B. Reference numeral 65 is attached to two through holes through which the through wire L3 penetrates the bearing fitting 6A and the bearing fitting 6B. The through lines L2 and L3 form a preset angle. This angle is 60 degrees in this embodiment.

As shown in FIG. 4C, the rotary bearing 6 abuts the bearing fittings 6 </ b> A and 6 </ b> B with the tongue pieces 62 at four locations, and forms a cylinder that accommodates the end of the rotary shaft tube 4. It is a thing. The center lines of the through holes 64 of the bearing fittings 6A and 6B coincide with each other (through line L2). Therefore, when the angle adjusting pin is inserted into the through hole 64 from the outside of the bearing fitting 6B, it protrudes to the outside of the through hole 64 of the bearing fitting 6A. The same applies to the through hole 65.

As shown in FIG. 5A, the bearing fitting 6A is fixed to the upper end portion 53 of the column 5 by welding in a reverse Ω shape when viewed from the front. FIG. 5B is a side view showing a state in which the bearing fitting 6A is fixed.
In order to fix the bearing fitting 6A, a substantially semicircular recess 53A is formed in the upper end portion 53 of the support column 5 so that the bearing fitting 6A having a semicircular cross section can be fitted. Since this bearing fitting 6A mounts the end portion of the round pipe-shaped rotary shaft tube 4, the inner diameter of the recess 53A is set so that the lower half of the end portion of the rotary shaft tube 4 can be fitted. 4 is slightly larger than the outer diameter.

The rotary shaft tube 4 is placed on the bearing bracket 6 </ b> A, and the bearing bracket 6 </ b> B is put on the rotary shaft tube 4. As a result, the end of the rotary shaft tube 4 is accommodated in the cylindrical interior of the rotary bearing 6. FIG. 6A shows a front view of this state.
In the state where the end of the rotary shaft tube 4 is accommodated in the rotary bearing 6, the screw holes 63 of the tongue pieces 62 that are vertically overlapped with each other are stopped with screws 66, whereby the upper bearing fitting 6B and the lower bearing fitting 6B are fixed. The bearing fitting 6A is securely joined.
As shown in FIG. 6B, the end of one rotary shaft tube 4 may be supported by the rotary bearing 6, but as shown in FIG. The ends of the two rotary shaft tubes 4 may be supported.

If the end of the rotary shaft tube 4 is accommodated in the rotary bearing 6, the rotary shaft tube 4 is fixed as follows.
As shown in FIG. 7, it rotates so that the through-hole (42 or 43) provided in the edge part of the rotating shaft tube 4 and the through-hole (64 or 65) provided in the rotating bearing 6 are arrange | positioned in the same straight line form. The position of the shaft tube 4 is adjusted. This adjustment is performed by rotating the both ends of the rotating shaft tube 4 by an appropriate angle in a state where the both ends are accommodated in the cylindrical interior of the rotary bearing 6. The angle adjusting pin penetrating portion is formed by the through holes arranged in a straight line. In the example of FIG. 7, the angle adjusting pin penetrating portion is formed from the through hole 65 of the bearing fitting 6B, the two through holes 42 penetrating the rotating shaft tube 4, and the through hole 65 of the bearing fitting 6A. A one-dot chain line L4 represents the center line of the angle adjustment pin penetrating portion. The rotary shaft tube 4 is fixed to the column 5 by inserting the angle adjustment pin 11 into the angle adjustment pin penetrating portion. 8A is a side view of the state in which the angle adjustment pin 11 is inserted, and FIG. 8B is an XX cross-sectional view of FIG.

Hereinafter, a procedure for installing the solar panel will be described.
First, the leg portion 51 of the column 5 is fixed to the concrete base 9 on the ground surface with an anchor (see FIG. 1). Thereby, the column part 52 of the support | pillar 5 stands upright perpendicularly | vertically on the ground.
The end of the rotating shaft tube 4 is placed in the recess of the bearing fitting 6A of the rotary bearing 6 attached to each upper end portion 53 of the two columns 5, and the end of the rotating shaft tube 4 is covered with the bearing fitting 6B. Then, the corresponding tongue piece 62 of the bearing fitting 6A, 6B is screwed. In consideration of the inclination angle of the solar panel 2, the through hole 42 (or 43) provided at the end of the rotary shaft tube 4 and the through hole 64 (or 65) provided in the rotary bearing 6 are arranged on the same line. And pin it.

Here, the case where the solar panel 2 is installed at an inclination angle of 60 degrees with respect to the horizontal plane will be described with reference to FIG. In FIG. 9A, the reference symbol P denotes the attachment location (reference point P) of the fixing bolt 7 of the rotating shaft tube 4 (see FIG. 2B). In order to install the solar panel at an inclination angle of 60 degrees, the line connecting the point P and the center O of the rotating shaft tube 4 shown in FIG. 9B becomes 30 degrees from the horizontal state. (FIG. 9C).
Since the through-hole 64 of the rotary bearing 6 and the through-hole 42 provided at the end of the rotary shaft tube 4 are aligned on a straight line to form an angle adjusting bin through-portion (the center line is indicated by a one-dot chain line L5). The angle adjusting pin 11 is inserted into this. Thereby, a solar panel can be attached at a 60 degree | times inclination angle like FIG. 9 (A).

In this way, the rotary shaft tube 4 rotated to a desired angle is fixed to the support column 5 via the rotary bearing 6, and a plurality of vertical members 3 are bolts 7 and 8 on the rotary shaft tube 4 as shown in FIG. The solar panel 2 is attached to the upper side of the frame material made up of a plurality of vertical members 3.
This completes the work for installing the solar panel 2.

By the way, when the altitude of the sun changes compared to the time when the above installation was performed, it is desired to change the inclination of the solar panel in order to increase the power generation efficiency. Here, a case where the inclination angle is changed from 60 degrees to 30 degrees will be described.
When the solar panel is installed at an inclination angle of 30 degrees with respect to the horizontal plane as shown in FIG. 10A, the point P and the center of the rotary shaft tube 4 as shown in FIG. The rotary shaft tube 4 is rotated 60 degrees clockwise as shown in FIG. 10C from the state where O is horizontal. Since the through hole 65 of the rotary bearing 6 and the through hole 43 provided at the end of the rotary shaft tube 4 are aligned on a straight line to form an angle adjusting bin through part (the center line is represented by a one-dot chain line L6). The angle adjusting pin 11 is inserted into this. Thereby, a solar panel can be inclined 30 degree | times like FIG. 10 (A).

In order to rotate the rotating shaft tube 4 as shown in FIG. 10C, the angle adjusting pin 11 inserted into the angle adjusting pin penetrating portion (center line is the one-dot chain line L5) in FIG. 9C is once removed. The rotary shaft 6 rotates 30 degrees clockwise from the state of FIG. 9C while the end of the rotary shaft tube 4 is accommodated in the cylindrical interior of the rotary bearing 6. If the through hole at the end of the rotary shaft tube 4 and the through hole of the rotary bearing 6 are aligned in a straight line and an angle adjusting pin penetrating portion (center line is a one-dot chain line L6) is formed, Reattach the angle adjustment pin 11. At this time, it is not necessary to remove the vertical member 3 fixed to the rotating shaft tube 4 with the bolts 7 and 8. The solar panel 2 can be simply obtained by rotating the rotating shaft tube 4 by a desired angle and reattaching the angle adjusting pin 11. The inclination angle can be changed.
As described above, since the vertical member 3 and the solar panel 2 fixed to the rotary shaft tube 4 are attached, only the insertion position of the angle adjusting pin 11 is manually changed, so that no special equipment is required. Can be done quickly.

The above embodiments are merely examples.
For example, in the above embodiment, the frame material that supports the solar panel 2 from the back side is composed of a plurality of vertical members 3, but a beam in which two or more vertical members and two or more cross members are combined. The solar panel 2 may be supported by a frame-shaped frame material.
In said embodiment, although the inclination angle of the solar panel was demonstrated as two types of 30 degree | times and 60 degree | times, it is not restricted to this. Further, at the end of the rotating shaft tube 4, there are a through hole 42 and a through hole 43 whose center lines are orthogonal to each other (see FIGS. 9 and 10), but the number of through holes is not limited to two. Similarly, the rotational bearing 6 may have three or more through holes. This is because by providing through holes with different angles, fine angle adjustment is possible.

When installing solar panels outdoors on the ground or on a flat building rooftop, there is a great demand for a solar panel installation stand that allows the inclination angle of solar panels to be changed easily and quickly according to seasonal changes. Can be expected.
