In the first embodiment, the directions regarding the X direction and the Y direction on the installation surface 2 are defined as shown in FIG. 1, and the following description will be given.

As shown in FIG. 1, the rainwater recovery device 1 of the solar panel S according to the first embodiment has a gantry 11 arranged on an installation surface 2 such as a sloped land in a mountainous area and a gantry 11 on the gantry 11 in the X direction. A total of 48 solar panels S, 12 in the Y direction, are arranged in a row, and a rainwater gutter unit 21 arranged on the outflow side of rainwater flowing down the solar panel surface. Have.

In the pedestal 11, the required number of pedestal supports 12 are scattered on the installation surface 2 at intervals, the required number of pedestal columns 13 are projected upward from each pedestal support 12, and each pedestal support is further arranged. A gantry plate 14 is attached to the upper end of the gantry plate 14, and a total of 48 solar panel S are arranged in a row on the gantry plate 14.

The adjacent region (joint region) of each of the solar panel S is subjected to a sealing process or a sealing process with an aluminum material to prevent water leakage.

Next, each part of the gutter unit 21 will be described with reference to FIGS. 2 to 6.

The gutter unit 21 is arranged along each of the solar panels S supported by the gantry 11, and rainwater W (indicated by a white arrow in FIG. 1) flowing down the surface (upper surface) of the solar panel S. (Shown) is received, and rainwater W is discharged downward from a plurality of or a single hole 32 as shown in FIG. 4 provided at an intermediate position of the bottom of the gutter, and a plurality of or a single water discharge cylinder 33 projecting downward from the bottom of the gutter. An upper gutter 31 having an arc-shaped (or square shape) cross section to be flowed down, and rainwater W which is arranged below the upper gutter 31 and flows down from a hole 32 of the upper gutter 31 are received and are the most in the length direction. A lower gutter 41 having a structure in which rainwater W is discharged from the lowermost portion in the length direction through a water discharge cylinder 42 and a lower gutter 41 having a bidirectional downward slope shape from the top portion toward the lowest portion in the length direction at both ends thereof. A lower gutter support base 52 for supporting the lower gutter in a fixed position, a lower gutter support portion 51 having a lower gutter support column 53, and a release provided on the lowermost portion side in the length direction of the lower gutter 41 via the upper gutter 31. Although not shown, the rainwater W discharged from the water cylinder 42 is configured to be sent toward a gutter or a gutter for drainage.

As shown in FIG. 2, the upper gutter 31 is connected to the pedestal column 13 in the pedestal 11 by the connecting member 34 in order to reduce the load load on the lower gutter supporting portion 51, whereby the pedestal 11 It is configured to be supported.

The upper gutter 31 has an arc shape opposite to the side wall portion 32a which has an arc shape along the lower end side (lower end side 14a of the gantry plate 14) of the solar panel S of the upper gutter 31. The side wall portion 32b is warped more greatly to form a gutter-shaped projecting piece portion 32c on the protruding end side of the side wall portion 32b, whereby the flow rate of rainwater W flowing down the upper surface of each solar panel S is large. In such a case, the rainwater W is prevented from overflowing outward (toward the front side in FIG. 1) from the side wall portion 32b of the upper gutter 31.

Further, in the upper gutter 31, the protruding end of the side wall portion 32a and the pedestal plate having an arc shape along the lower end side (lower end side 14a of the gantry plate 14) of the solar panel S of the upper gutter 31.

Is made to flow smoothly into the lower gutter 41.

Furthermore, if the arrangement of the solar panels S is long in the X direction and the area is wide, the amount of rainwater will increase in large quantities. Therefore, due to the nature of rainwater W flowing from high places to low places, in order to improve drainage efficiency. It is necessary to reduce the slope of the upper gutter 31, but if the arrangement of the solar panels S is long, the upper gutter 31 will inevitably become longer, and near the drainage ditch, between the end face of the solar panel S and the upper gutter 31. Since a large gap 35 is formed in the gutter and it becomes difficult to completely recover the rainwater W, a gutter two-stage structure including the gap shielding member 36 is adopted.

FIG. 3 shows a gutter unit 21A which is a modification of the gutter unit 21, in which the upper gutter 31C and the lower gutter 41C both have a cross-sectional angle shape, and both sides of the upper gutter 31C. Of the wall portions 32a1 and 32b1, the vertical dimension of the side wall portion 32b1 on the side opposite to the side wall portion 32a1 along the lower end side 14a of the gantry plate 14 supporting the solar panel S of the upper gutter 31C is shown. As shown in 3, it is configured to exert a sneak-back function by setting it large, so that when the flow rate of rainwater W flowing down the upper surface of each of the solar panels S is large, the rainwater W becomes It prevents the upper gutter 31C from overflowing outward (toward the front side in FIG. 1) from the side wall portion 32b1.

Even in the case of the gutter unit 21A, arranging the gap shielding member 36 as needed is the same as in the case of the gutter unit 21.

FIG. 4 shows an example of forming the shape and spacing of the hole 32 in the upper gutter 31, for example, the shape of the hole 32 is a slightly large elliptical shape with a major axis of about 15 cm, and the hole. For example, the arrangement interval of 32 is about 1 m.

As a result, it is possible to prevent the hole 32 of the upper gutter 31 from being clogged with dust such as dead leaves and causing the rainwater W to overflow.

5 and 6 show an example of installation configuration of the lower gutter support base 52 constituting the lower gutter support portion 51, and as shown in FIG. 5, the lower gutter support base 52 is installed in the installation surface 2. As shown in FIG. 6, a concrete block 54 is installed on the installation surface 2 of the lower gutter support base 52, and the concrete block 54 supports the lower gutter support base 52. An example of a compact installation type can be given.

With such an installation configuration of the lower gutter support base 52 in the lower gutter support portion 51, the lower gutter 41 can be supported reliably and stably. The same applies to the modified examples of Example 2 and Example 1 described later.

The upper gutter 31, lower gutter 41, upper gutter 31C, and lower gutter 41C are formed into substantially the same shape with an arc-shaped cross-sectional shape or a square cross-sectional shape, whereby the upper gutter 31, lower gutter 41, and upper gutter 31C are formed. , We are trying to reduce the manufacturing cost at the time of manufacturing the lower gutter 41C.

The rainwater recovery device 1 of the solar panel S according to the first embodiment of the present invention will be described with reference to FIGS. 1 to 6.

In the first embodiment, the directions regarding the X direction and the Y direction on the installation surface 2 are defined as shown in FIG. 1, and the following description will be given.

As shown in FIG. 1, the rainwater recovery device 1 of the solar panel S according to the first embodiment has a gantry 11 arranged on an installation surface 2 such as a sloped land in a mountainous area, and a gantry 11 on the gantry 11 in the X direction. A total of 48 solar panels S, 12 in the Y direction, are arranged in a row, and a rainwater gutter unit 21 arranged on the outflow side of rainwater flowing down the surface of the solar panel. Have.

In the pedestal 11, the required number of pedestal supports 12 are scattered on the installation surface 2 at intervals, the required number of pedestal columns 13 are projected upward from each pedestal support 12, and each pedestal support is further arranged. A gantry plate 14 is attached to the upper end of the gantry plate 14, and a total of 48 solar panels S are arranged in a row on the gantry plate 14.

The adjacent region (joint region) of each of the solar panels S is subjected to a sealing process or a sealing process with an aluminum material to prevent water leakage.

Next, each part of the gutter unit 21 will be described with reference to FIGS. 2 to 6.

The gutter unit 21 is arranged along each of the solar panels S supported by the gantry 11, and rainwater W (indicated by a white arrow in FIG. 1) flowing down the surface (upper surface) of the solar panel S. (Shown) is received, and rainwater W is discharged downward from a plurality of or a single hole 32 as shown in FIG. 4 provided at an intermediate position of the bottom of the gutter, and a plurality of or a single water discharge cylinder 33 projecting downward from the bottom of the gutter. An upper gutter 31 having an arc-shaped (or square shape) cross section to be flowed down, and rainwater W which is arranged below the upper gutter 31 and flows down from a hole 32 of the upper gutter 31 are received and are the most in the length direction. A lower gutter 41 having a structure in which rainwater W is discharged from the lowermost portion in the length direction through a water discharge cylinder 42 and a lower gutter 41 having a bidirectional downward slope shape from the top portion toward the lowest portion in the length direction at both ends thereof. A lower gutter support base 52 for supporting the lower gutter in a fixed position, a lower gutter support portion 51 having a lower gutter support column 53, and a release provided on the lowermost portion side in the length direction of the lower gutter 41 via the upper gutter 31. Although not shown, the rainwater W discharged from the water cylinder 42 is configured to be sent toward a gutter or a gutter for drainage.

As shown in FIG. 2, the upper gutter 31 is connected to the pedestal column 13 in the pedestal 11 by the connecting member 34 in order to reduce the load load on the lower gutter supporting portion 51, whereby the pedestal 11 It is configured to be supported.

The gutter unit 21 will be described in more detail.

The upper gutter 31 has an arc shape opposite to the side wall portion 32a, which has an arc shape along the lower end side (lower end side 14a of the gantry plate 14) of the solar panel S of the upper gutter 31. A projecting piece portion 32c in a form bent toward the lower end side side of the solar panel located above the side wall portion 32b (sneaking back form) is formed, whereby the upper surface of each solar panel S flows down. When the flow rate of the rainwater W is large, the rainwater W is prevented from overflowing from the side wall portion 32b of the upper gutter 31 to the outside (front side in FIG. 1).

Further, in the upper gutter 31, the protruding end of the side wall portion 32a and the pedestal plate having an arc shape along the lower end side (lower end side 14a of the gantry plate 14) of the solar panel S of the upper gutter 31. When a gap 35 is generated between the lower end side 14a of the 14 and the gap 35, the gap 35 is closed by a gap shielding member 36 made of, for example, a waterproof rubber material, and rainwater W flowing down the upper surface of the solar panel S. Is made to flow smoothly into the lower gutter 41.

Furthermore, if the arrangement of the solar panels S is long in the X direction and the area is wide, the amount of rainwater will increase in large quantities. Therefore, due to the nature of rainwater W flowing from high places to low places, in order to improve drainage efficiency. It is necessary to reduce the slope of the upper gutter 31, but if the arrangement of the solar panels S is long, the upper gutter 31 will inevitably become longer, and near the drainage ditch, between the end face of the solar panel S and the upper gutter 31. Since a large gap 35 is formed in the gutter and it becomes difficult to completely recover the rainwater W, a gutter two-stage structure including the gap shielding member 36 is adopted.

FIG. 3 shows a gutter unit 21A which is a modification of the gutter unit 21, in which the upper gutter 31C and the lower gutter 41C both have a cross-sectional angle shape, and both sides of the upper gutter 31C are formed. Of the wall portions 32a1 and 32b1, the vertical dimension of the side wall portion 32b1 on the side opposite to the side wall portion 32a1 along the lower end side 14a of the gantry plate 14 supporting the solar panel S of the upper gutter 31C is shown. 3 to be set large as shown by this, wherein when the flow rate of the rainwater W running down the upper surface of each solar panel S is such a large amount, from the side wall portion 32b1 of the rainwater W the upper trough 31C It prevents it from overflowing to the outside (front side in FIG. 1).

Even in the case of the gutter unit 21A, arranging the gap shielding member 36 as needed is the same as in the case of the gutter unit 21.

FIG. 4 shows an example of forming the shape and spacing of the hole 32 in the upper gutter 31, for example, the shape of the hole 32 is a slightly large elliptical shape with a major axis of about 15 cm, and the hole. For example, the arrangement interval of 32 is about 1 m.

As a result, it is possible to prevent the hole 32 of the upper gutter 31 from being clogged with dust such as dead leaves and causing the rainwater W to overflow.

5 and 6 show an installation configuration example of the lower gutter support base 52 constituting the lower gutter support portion 51, and as shown in FIG. 5, the lower gutter support base 52 is installed in the installation surface 2. As shown in FIG. 6, a concrete block 54 is installed on the installation surface 2 of the lower gutter support base 52, and the concrete block 54 supports the lower gutter support base 52. An example of a compact installation type can be given.

With such an installation configuration of the lower gutter support base 52 in the lower gutter support portion 51, the lower gutter 41 can be supported reliably and stably. The same applies to the modified examples of Example 2 and Example 1 described later.

The upper gutter 31, lower gutter 41, upper gutter 31C, and lower gutter 41C are formed into substantially the same shape with an arc-shaped cross-sectional shape or a square cross-sectional shape, whereby the upper gutter 31, lower gutter 41, and upper gutter 31C are formed. , We are trying to reduce the manufacturing cost at the time of manufacturing the lower gutter 41C.
