Description

  The present invention relates to a solar energy utilization device such as a solar battery panel installed on an inclined roof of a building.

  Conventionally, a solar panel is installed on the roof as a solar energy utilization device, but if the snow falls on the solar panel due to snowfall in winter, the panel surface is covered with snow and can receive sunlight. There is a problem that the solar cell panel cannot be used effectively.

  Regarding such a problem, for example, Patent Document 1 relates to an installation structure of a solar cell panel that is installed on an inclined roof, and a structure for making it easy for snow on the solar cell panel to slide down during a snowfall is proposed. ing. Specifically, in a configuration using a sealing material at the edge portion of the solar cell panel on the underwater side, a structure for facilitating snow slipping is proposed.

Japanese Patent Laid-Open No. 2007-120054

  On the other hand, in the structure which hold | maintains the edge part of the underwater side of a solar cell panel, the structure shown by FIG. 5 can be considered, for example. In this structure, it is set as the structure which presses the panel frame 32 provided in the edge of the panel material 31 from the upper part in the latching | locking part 22B.

  However, when the locking portion 22B is configured to cover up to the tip of the upper side portion 35 of the panel frame 32, a series of vertical wall surfaces 36 substantially perpendicular to the panel surface 31a by the locking portion 22B and the upper side portion 35. Is formed, and a step of height H4 is formed in the vertical direction with respect to the panel surface 31a.

  And the snow 60 cannot get over this vertical wall surface 36, and the snow 60 is stopped and stagnated on the vertical wall surface 36, cannot slide down, and the snow remains on the panel surface 31a.

  When the snow 60 stagnates on the vertical wall surface 36 in this way, the snow that has reached the portion of the snow 60 from the underwater side further accumulates, and in addition, the vertical wall surface 36 is frozen by time. There is also a concern that a snow mass accumulates for a long time at the part.

  Once a lump of snow is formed, the snow that slides down from the water side accumulates, and the lump of snow gradually increases to form a large dam, creating a situation where the snow is more difficult to slide down. It will end up.

  Therefore, in view of the above problems, the present invention relates to a solar energy utilization device such as a solar battery panel installed on the roof of a building, and a novel structure in which snow slides down at the edge portion on the underwater side of the panel. It is what we propose.

  Panel manufacturers who manufacture solar cell panels can design the shape of the panel itself, so the above-mentioned issues can be dealt with by changing the design of the panel shape (panel frame shape). However, since the frame manufacturer using the general-purpose panel module cannot freely change the design of the general-purpose panel module, it is necessary to make a unique design for the structure of the frame. This is a problem that requires a particular solution for the frame manufacturer.

  The problem to be solved by the present invention is as described above. Next, means for solving the problem will be described.

Moreover, as described in claim 2,
The second height, which is the highest position of the locking portion, is configured to be substantially the same as or lower than the first height, which is the highest position of the panel frame. It is set as the mount frame of the solar energy utilization apparatus of Claim 1.

Moreover, as described in claim 3,
The end surface of the water-side end of the locking portion is configured by an inclined surface that extends from the second step side formed by the panel frame and the locking portion toward the water side. It is set as the mount of the solar energy utilization apparatus of Claim 1 or Claim 2.

  As effects of the present invention, the following effects can be obtained.

That is, in the invention according to claim 1,
The second step formed by the panel frame and the locking portion can be arranged to be shifted below the first step formed by the panel frame and the panel surface. As compared with a configuration in which snow is easily damped by being arranged at the same position in the inclination direction, a configuration in which snow is easy to slide down can be realized.

In the invention according to claim 2,
Once the snow reaches the first height, it becomes easy to slide down to a position that is the same as or lower than that height, so that a configuration that prevents snow from being damped is realized.

In the invention according to claim 3,
Compared with the case where it is configured by a vertical surface to which no gradient is applied, the configuration is such that the snow easily gets over the second step.

  The second height 52 is configured to be substantially the same as the first height 51 or lower than the first height 51.

A specific example following the above configuration is shown in FIGS.
<Example 1>
The example of FIG. 4A has the following characteristic elements.
Element 1: The second step 42 is disposed below the first step 41 by a distance D1 in the roof inclination direction D.
Element 2: The second height 52 is configured to be substantially the same as the first height 51 or lower than the first height 51.
Element 3: The latching | locking part 22 has the 1st inclined surface 22a which becomes high toward the underwater side from the 2nd level | step difference 42 side.

<Example 2>
The example of FIG. 4B has the following characteristic elements.
Element 1: The second step 42 is disposed below the first step 41 by a distance D2 in the roof inclination direction D.
Element 2: The second height 52 is configured to be substantially the same as the first height 51 or lower than the first height 51.
Element 3: The locking portion 22 has a first inclined surface 22d that extends from the second step 42 side toward the water side.

<Comparative example>
The configuration shown in FIG. 5 is given as a comparison with the above configuration. In this configuration, the locking portion 22B covers the tip of the upper side portion 35 of the panel frame 32, and the locking portion 22B and the upper side portion 35 constitute a series of vertical wall surfaces 36 that are substantially perpendicular to the panel surface 31a. Has been. The vertical wall surface 36 forms a step having a height H4 in the vertical direction with respect to the panel surface 31a.

  And the snow 60 cannot get over this vertical wall surface 36, and the snow 60 is stopped and stagnated on the vertical wall surface 36, cannot slide down, and the snow remains on the panel surface 31a. The vertical wall surface 36 is formed so that the first step 41 and the second step 42 in the configuration of FIGS. 4A and 4B are arranged at the same position in the tilt direction.

Compared with the comparative example of FIG. 5, in the first embodiment shown in FIG. 4A, the vertical wall surface 36 that blocks the snow 60 as shown in FIG. 5 is not formed, so that the snow slides down due to the inclination of the panel surface 31a. Easy configuration.
That is, the second step 42 is configured to be shifted to the lower side of the first step 41 by the element 1, and the step heights H1 and H2 at the respective steps 41 and 42 can be reduced. A structure that prevents snow from being damped is realized. If H1> H2, it is easy for snow that has slipped over the height of H1 to get over the lower H2.
Also, because the second height 52 is lower than the first height 51 due to the element 2, the snow once reaching the first height 51 slides down to a position equal to or lower than that height. It becomes easy, and the structure which is hard to stop snow is realized.
In addition, since the first inclined surface 22a is inclined by the element 3, the snow climbs over the second step 42 as compared with the case where the first inclined surface 22a is configured with a vertical surface (imaginary line 32n) that is not inclined. Easy configuration.

  Similarly, also in Example 1 shown in FIG.4 (b), the structure by which snow is easy to slide down compared with a comparative example is implement | achieved by the elements 1-3.

  Among elements 1 to 3 described above, element 1 is particularly effective, and even when element 1 is implemented alone, an effect that snow can easily slide down can be expected. Further, the present invention can be implemented as long as the elements 1 to 3 are realized, and the present invention is not limited to the embodiment shown in FIGS. 4 (a) and 4 (b).

The present invention can be implemented as described above.
That is, as shown in FIGS. 3 and 4 (a) and 4 (b), the use of solar energy for holding the panel frame 32 attached to the lower end of the panel material 31 inclined to be held by the crosspiece member 20. Utilizing solar energy, the device frame (installation frame), wherein the panel frame 32 is pressed from above by the locking portion 22 at a position shifted from the water-side end of the panel frame 32 to the water side. It will be a frame for the device.

  As a result, the second step 42 formed by the panel frame 32 and the locking portion 22 can be shifted and disposed below the first step 41 formed by the panel frame 32 and the panel surface 31a. In addition, since the first step 41 and the second step 42 are arranged at the same position in the inclination direction, it is possible to realize a configuration in which snow is easily slipped down compared to a configuration in which snow is easily damped.

  In addition, the second height 52 that is the highest position of the locking portion 22 is configured to be substantially the same as or lower than the first height 51 that is the highest position of the panel frame 32. It shall be.

  As a result, the snow that has once reached the first height 51 is likely to slide down to a position that is the same as or lower than that height, so that a structure that does not dampen the snow is realized.

  Further, the end surface of the water-side end of the locking portion 22 is configured by an inclined surface that extends from the second step 42 side formed by the panel frame 32 and the locking portion 22 toward the water side. To do.

  Thereby, compared with the case where it comprises with the vertical surface (imaginary line 32n) where a gradient is not provided, it will become the structure which snow tends to get over the 2nd level | step difference 42. FIG.

  Moreover, the latching | locking part 22 shall be formed in the cap material 21 integrally formed with the horizontal beam member 20, or being fixed to the horizontal beam member 20 from an upper side.

  When the locking portion 22 is formed integrally with the crosspiece member 20, the number of parts can be reduced. When the locking portion 22 is provided on the cap material 21, the shape or the like of the locking portion 22 can be designed independently of the structure of the crosspiece member 20.

  The configuration of the present invention can be widely applied to solar energy utilization devices such as solar cell panels installed on the roof of a building.
