Description

[Detailed Description of the Invention] <Technical Field> The present invention relates to a solar cell mount capable of adjusting the angle of incidence of sunlight on the solar cell.

Solar energy can be maximized by placing multiple silicon wafers with PN junctions encapsulated in a case made of synthetic resin such as acrylic, with the surface of the solar cell perpendicular to the sun's rays. For this reason, a method is known that automatically adjusts the angle of a solar cell so that sunlight is always kept perpendicular to the surface of the solar cell, regardless of changes in season or time.

However, this method has the disadvantage of requiring large-scale equipment and significantly increasing the price, so conventionally a method has been adopted in which the angle of the solar cells is adjusted only several times a year depending on the season.

FIG. 1 shows a side view of a solar cell mount that adopts this method. By rotatably supporting one end of the arm 4 and fixing both ends of the arm 4 to the support base 1 and the holder 3, respectively, the holder 3 is held at a fixed angle.

According to this method, any desired angle can be obtained by simply changing the length of the arm 4, so it has the advantage of being very easy to manufacture by focusing only on the arm.

However, when considering installation locations or sales locations all over the world, the latitudes and seasons of each country are significantly different, so it is necessary to prepare a number of types of arms 4 with different lengths. For this reason, if the expected orders for about six months to one year are produced all at once, the production and inventory management expenses for Arm 4 cannot be ignored, which causes a significant cost increase, and this also causes the expected production to be stopped. This created a vicious cycle in which delivery times were significantly delayed.

<Objective> Therefore, the object of the present invention is to provide a solar cell mount that can arbitrarily change the angle of the solar cell holder with respect to the fixed support base.

Another object of the present invention is to provide a solar cell mount equipped with a simple and inexpensive angle variable mechanism.

<Example> The present invention will be described in detail below based on the figures.
FIG. 2 is a front view of the solar cell mount according to the present invention, and FIG. 3 is a side view of the same.

In the figure, 1 is a fixed support base combined into a rectangular shape by angle members, 3 is a solar cell holder on which a solar cell 4 and a bird guard 5 are mounted, and one end of this holder 3 is Rotatable support part 2
It is rotatably supported at the end of the support base 1 by a.

As shown in FIG. 2, the dimensions of both sides of the fixed support base 1 are determined to be approximately the same as the width of the solar cell holder 3, or slightly smaller than that. Further, a plurality of angle adjustment holes 6 and 6' are bored in the angle member of the support base 1 at appropriate intervals in the longitudinal direction of the member.

7 is the maximum length arm that defines the maximum angle of the solar cell holder 3 with respect to the support base 1; 8 is the minimum length arm that defines the minimum angle; 9 is connected to the maximum length arm 7 and the minimum length arm 8; This is an intermediate long arm that supports the solar cell holder 3 between the maximum and minimum angles.

Holes into which bolts can be inserted are provided at both ends of the arms 7, 8, and 9, respectively, and the maximum length arm 7 and the intermediate length arm 9 are provided with appropriate intervals in the longitudinal direction, similar to the support base 1. There are multiple holes spaced apart.

According to this configuration, first, one of the maximum length arms 7 is fixed to the free end of the solar cell holder 3, and the other is fixed to the hole 6' of the fixed support base 1 with bolts and nuts, and then the support base 1 is fixed. The solar cell holder 3 can be held at the maximum angle, and the minimum length arm 8 can be used instead of the maximum length arm 7.
If this is used, the solar cell holder can be held at the minimum angle as shown by 3' in the figure.

Further, one of the maximum length arms 7 is attached to the free end of the holder 3, and the other is attached to the appropriate angle adjustment hole 6 of the support base 1.
and the hole of this maximum length arm 7 and the support base 1
While connecting the intermediate length arm 9 to the hole 6',
When the minimum length arm 8 is connected to the appropriate holes of the maximum length arm 7 and the intermediate length arm 9, the state shown by 3'', 7', 8', and 9 in the figure is obtained, and the solar cell holder 3'' can be held at an appropriate angle between the maximum and minimum angles.

Therefore, the angle of the holder 3 can be arbitrarily varied between the maximum and minimum angles by changing the connection position of the maximum length arm 7' to the adjustment hole 6. especially,
Since each arm is connected in a triangular shape as shown,
It is possible to reliably hold the heavy solar cell holder 3.

In addition, if the length of each arm and the number and pitch of holes provided in the arm and the support base 1 are considered,
The angle of the solar cell holder 3 can be set in small increments over a wide range.

In addition, when conventionally multiple frames were installed side by side, the support base, which was wider than the holder, got in the way and it was not possible to fit each frame closely together, requiring a large installation space, but the frame of the present invention Since the width of the support base 1 is made to be the same as or a little smaller than that of the holder 3, each frame can be installed in close contact with each other as shown in FIG.

<Effects> As described above, according to the solar cell mount of the present invention, the angle of the solar cell holder can be arbitrarily varied using only three arms of different lengths. In particular, when supporting the solar cell holder at an arbitrary angle between the maximum and minimum angles, the three arms are connected in a triangular shape and can reliably hold the heavy solar cell holder. Therefore, it is possible to provide a solar cell mount that is simple, inexpensive, and highly productive.
