About.

  In a conventional solar cell panel installation base for installing a solar cell panel module, a plurality of solar cell panel modules are arranged on an inclined base in order to allow sunlight to efficiently strike the solar cell panel module. . Steel materials having various cross-sectional shapes such as an L-shaped cross section, a U-shaped cross section, an H-shaped cross section, and a C-shaped cross section are used for the gantry. The gantry is configured by fixing members such as a base, a pillar, a mounting table, and a reinforcing material with bolts and nuts. A predetermined gap is provided between each solar cell panel module to be installed in consideration of the assembly variation of the gantry member and considering expansion and contraction due to heat. Surface treatments such as corrosion resistant coating and hot dip galvanizing are often used for each steel material of the gantry.

  The following Patent Document 1 has been proposed for the purpose of suppressing rust and corrosion generated in the steel material of the gantry.

  FIG. 14 is a side view of a solar cell device in which a plurality of solar cell panels are installed on a conventional solar cell panel installation frame disclosed in Patent Document 1.

  In FIG. 14, a solar cell device 100 includes a solar cell panel 101 and a solar cell panel installation base 102 on which the solar cell panel 101 is mounted.

  The solar cell panel installation base 102 includes a main material 103 arranged in an inclined manner, a short vertical pillar member 104 that supports the main material 103 on the inclined lower side, and a vertical direction that supports the main material 103 on the inclined upper side. A long rear pillar member 105, a base member 106 for fixing each skirt portion of the front pillar member 104 and the rear pillar member 105, a connecting plate 107 for connecting the oblique member 108 and the rear pillar member 105, which will be described later, and a main member 103. And an oblique member 108 spanned between the connecting plates 107, and a base 109 for fixing the base member 106 and standing the front pillar member 104 and the rear pillar member 105 upright.

  The main material 103 is located on the solar cell panel installation base 102 on the side on which sunlight enters, and a plurality of solar cell panels 101 are placed and fixed thereon. The main material 103 is disposed to be inclined with respect to the flat surface portion GL of the roof.

  The front column member 104 has its upper end fixed to the side surface of the main member 103. The lower end side of the front column member 104 is fixed to the base member 106.

  The rear column member 105 has its upper end fixed to the side surface of the main member 103. The lower side of the rear column member 105 is fixed to the base member 106. In order to incline the main material 103, the rear pillar material 105 is longer than the front pillar material 104.

  The diagonal member 108 is provided obliquely with respect to the rear column member 105. The oblique member 108 has its upper end fixed to the side surface of the main member 103. Further, the lower end portion of the diagonal member 108 is fixed to the connecting plate 107.

  The foundation 109 is fixed to the flat surface portion GL of the roof. The flat surface portion GL of the roof is an installation surface on which the solar cell panel installation base 102 is installed.

  FIG. 15 is an essential part enlarged cross-sectional view for explaining a state in which the snow melting water and rain water that have fallen on the upper surface of the solar cell panel 101 in FIG. 16 is a side sectional view taken along line CC of FIG.

  As shown in FIG. 15 and FIG. 16, first, the snow melting water and rain water falling on the upper surface of the solar cell panel 101 flow obliquely downward along the inclined surface on the solar cell panel 101.

  Next, the snowmelt and rainwater flowing obliquely downward on the upper surface of the solar cell panel 101 get over the upper surface of the frame 110 and flow into a flange 110 a formed on the outer side of the frame 110 between the solar cell panels 101. The snowmelt and rainwater overflowing from the flange 110a falls into the gaps between the flanges 110a.

  Thereafter, the snow melting water and rainwater R falling into the gaps between the flanges 110a are collected in the L-shaped portion constituted by the flat portion 111a and the extending portion 111c of the guide portion 111, and the main material 103 having an inverted L-shaped cross section. It flows from side to side in the width direction. The direction in which the snowmelt water and rainwater R flow is the front-rear direction in FIG. 13 (the direction perpendicular to the paper surface). The snowmelt and rainwater R flowing through the guide part 111 are guided to the protrusion part 111b by the surface tension and fall from the protrusion part 111b.

  The protruding portion 111 b is formed away from the main material 103 in the width direction of the main material 103. For this reason, it is possible to guide snow melting water and rainwater R to a location away from the main material 103. The snowmelt and rainwater R that have reached the projection 111b fall to the flat surface portion GL of the roof.

  Thus, the guide part 111 can guide the snow-melting water and rainwater R that have entered into the gap between the solar battery panels 101 (the gap between the flanges 110a) to a place away from the main material 103 and drop it. .

  In addition, the frame 110 to which the solar cell panel 101 is attached, the guide part 111 for melting snow and rainwater, and the inverted L-shaped main material 103 are fixed by the bolt 112 and the nut 113 on the upper and lower sides of the slope. . A solar cell panel module is configured including the solar cell panel 101 and the frame 110 at the end face thereof.

JP 2011-236673 A

  In the conventional solar cell device 100, the upper surfaces of the plurality of solar cell panels 101 on the solar cell panel installation base 102 are inclined. For this reason, the snow melting water and the rainwater R flow along the upper surface of the solar cell panel 101 to the low slope side and fall from the gap between the solar cell panels 101 (the gap between the flanges 110a). A guide portion 111 is disposed on the main material 103 inside the gap between the flanges 110a. For this reason, the snow melting water and rainwater R that flowed through the guide part 111 are guided to the protrusion part 111b side below the guide part 111 without getting wet with the main material 103, and fall on the roof from the protrusion part 111b.

  However, in the conventional guide part 111, since the snow melting water and the rain water R are received on the upper surface of the large area solar cell panel 101, a considerable amount of the snow melting water and the rain water R are introduced from the gap between the flanges 110a. Flow into. As a result, the snow melting water and rainwater R collected in the flat portion 111a and the extending portion 111c fall down to the protruding portion 111b side of the lower end, but the accumulated snow melting water and rainwater R fall from the opening of the guide portion 111. Since the width is inclined as shown in FIG. 13, the width can be wider than the width of the gap between the solar cell panels 101, and is considerably wider than the width of the protrusion 111 b on the lower surface of the guide portion 111. For this reason, the snow-melting water and rainwater R overflowing the guide part 111 are transmitted from both opening parts of the guide part 111 to the lower surface side without the projecting part 111b through the both end faces, and then guided to the lower projecting part 111b. It falls from the part 111b. For this reason, there is a great risk that the overflowing snowmelt water or rainwater R will reach the inverted L-shaped main material 103 along the lower surface of the guide portion 111.

  The main material 103 is subjected to a surface treatment for ensuring weather resistance and corrosion resistance, while the surface is slowly eroded while being exposed to snowmelt or rainwater R. When this erosion reaches the surface of the steel material, erosion is accelerated by the generation of rust. The mechanical strength which supports the solar cell panel 101 will reduce because the thickness of steel materials becomes thin by progress of erosion.

  In addition, when snowmelt water or rainwater R enters between the lower surface of the guide portion 111 and the upper surface of the inverted L-shaped main material 103, the main material 103 is exposed to snowmelt water or rainwater without drying for a long time. become. In addition, fixing bolt holes are formed in the main material 103 and the guide portion 111. For this reason, if the snow melting water or rainwater R penetrates between the lower surface of the guide portion 111 and the upper surface of the inverted L-shaped main material 103 and reaches the bolt hole, the inside of the bolt hole is corroded.

  Further, regarding the attachment of the guide portion 111, the frame 110 to which the solar cell panel 101 is attached, the guide portion 111 for melting snow and rainwater, and the inverted L-shaped main material 103 are fixed together by bolts 112 and nuts 113. doing. For this reason, the fastening by the bolt 112 and the nut 113 rotates together, and it takes time to mount the guide portion 111.

(Embodiment 1)
FIG. 1 is a plan view showing a configuration example of a main part of a draining cover according to Embodiment 1 of the present invention. FIG. 1A is a plan view in which flat portions inclined downward are continuously provided on both sides of a water guiding direction of a flat portion. FIG. 4B is a plan view in which a flat portion inclined downward is continuously provided on one side of the flat portion in the water guiding direction, and FIG. 4C is a schematic view showing a cross section of FIG. FIG. 2 is a front view of the draining cover of FIG. FIG. 3 is an enlarged side view of the draining cover of FIG.

  In FIG. 1A to FIG. 3, the drain cover 1 according to the first embodiment is configured by bending a plate. Both sides of the flat plane portion 1a having a quadrangular shape in the plan view are bent downward at a predetermined inclination angle θ1, and inclined portions are continuously provided on both sides of the central plane portion 1a. Both sides of the inclined portion in the width direction are configured to be higher than the flat portion 1b having a triangular shape in plan view, and the guide width is gradually narrowed. In other words, it is bent upward at a predetermined inclination angle θ2 from both sides in the width direction of the flat portion 1b in the plan view triangular shape (the base 1c in the plan view triangular shape) to the tip opening (the apex of the plan view triangular shape) as the outflow portion. Yes.

  The flat portion 1b having a triangular shape in plan view is connected to the central flat portion 1a via a base 1c having a triangular shape in plan view, and the apex portion facing the base 1c having a triangular shape in plan view has snow melting water, rainwater, or the like. It corresponds to a draining portion 1d which is a spout (tip opening portion) of water (hereinafter, typically referred to as rainwater). In short, the rainwater entering from the gap 3a between the solar cell panel modules 3 is guided to a position away from the main material 2 by the central plane portion 1a and the inclined portions on both sides thereof (including the flat portion 1b having a triangular shape in plan view). A guide unit is configured. A draining portion 1d is provided at a tip opening for guiding rainwater in the guide portion. The draining portion 1d is provided at a tip portion (an inverted triangular tip opening portion in FIG. 3) of a flat portion 1b having a triangular shape in plan view inclined downward. The rainwater is once expanded at the flat surface 1a until it reaches the tip opening, and does not overflow around. The rainwater flow cross-sectional area is squeezed from both sides to a nozzle shape from an inverted trapezoidal shape. Will be blown farther. If the rainwater flow rate Q is constant, the flow rate Q is the cross-sectional area A of the flow A × the flow velocity V. Therefore, when the cross-sectional area A of the rainwater flow is narrowed, the flow velocity V increases accordingly. Moreover, the rainwater flowing down the inclined portion further increases the flow velocity V. As described above, the rainwater flows out or is discharged or ejected from the tip opening, and even if the rainwater is reduced, the tip opening has a small opening area, so the draining effect is still good.

  Thus, after the periphery of the flat portion 1b having a triangular shape in plan view is bent upward, it is the same as the width in plan view of the central flat portion 1a so that it does not contact the lower surface of the solar cell panel module 3 during mounting. The main material guide 1e is formed by being bent vertically from the flat surface 1a so as to have a predetermined inclination angle θ3 (0 <θ3 <θ1).

  In the front view of FIG. 2, the main material guide portions 1 e are provided on both the left and right direction sides and the front and rear direction sides (width direction sides) of the draining cover 1. Between the main material guide portions 1e on both sides in the left-right direction, the main material fitting recesses have dimensions that allow the main material 2 to be fitted. Moreover, the main material fitting recessed part comprised inside the main material guide part 1e of the left-right direction both sides of the draining cover 1 is the entrance (main material guide part) of the main material 2 in order to make it easy to fit the main material 2 correctly. A taper portion is formed on the main material guide portion 1e so that 1e) is round and opens downward.

  As the material of the plate material of the draining cover 1, a stainless plate or a steel plate (for example, a galvalume steel plate) is used. In the case where a steel plate is used for the draining cover 1, a surface treatment such as corrosion resistant coating or hot dip galvanizing is applied. The draining cover 1 is formed by being bent from a developed shape of a thin plate material of about 0.4 mm.

  The draining cover 1 is used by sandwiching the flat portion 1a at the center of FIG. 1A between the lower main member 2 and the solar cell panel module 3 on the upper side. The drainage cover 1 is arranged at a position of the gap 3a between the solar cell panel modules 3 mounted on the main material 2 of the solar cell panel installation base so as to cover the main material 2.

  As the size of the draining cover 1, for example, when the gap 3a between the solar cell panel modules 3 is 5 mm, the width of the draining cover 1 is about 30 mm. As the size in the longitudinal direction of the draining cover 1, the longitudinal dimension of the central flat portion 1 a constituting a part thereof is longer than the width dimension of the main material 2.

  Here, the solar cell device 10 using the draining cover 1 will be described with reference to FIGS. 4 and 5.

  FIG. 4 is a side view of a solar cell device in which a plurality of solar cell panel modules 3 are installed on a solar cell panel installation base in Embodiment 1 of the present invention. FIG. 5 is a plan view schematically showing a state in which the draining cover 1 is mounted on the main material 2 of the solar cell panel installation stand of FIG.

A predetermined gap 3 a is provided between each solar cell panel module 3 installed on the main material 2 in consideration of the assembly variation of the gantry member and taking into account expansion and contraction due to heat.

  The drainage cover 1 is installed across the main material 2 of the solar cell panel installation base 11 in the width direction, and between the main material 2 and the solar cell panel module 3 immediately below the gap 3 a between the solar cell panel modules 3. It is sandwiched.

  Steel members having various cross-sectional shapes such as an L-shaped cross-section, a U-shaped cross-section, an H-shaped cross-section, and a C-shaped cross-section are used for the gantry member of the solar cell panel installation gantry 11. Each steel material is subjected to a surface treatment such as corrosion resistant coating or hot dip galvanizing.

  The solar cell panel installation stand 11 includes a main member 2, a front pillar member 12, a rear pillar member 13, a base member 14, a connecting plate 15, an oblique member 16, and a foundation 17 as a stand member. Yes. Each of these members is fixed with bolts and nuts.

  The main material 2 is disposed to be inclined. A plurality of solar cell panel modules 3 are mounted on the main material 2.

  The front column member 12 is erected on the front foundation 17 in the vertical direction, its upper end is fixed to the side surface of the main member 2, and its lower end is fixed to the base member 14 fixed to the foundation 17.

  The rear column member 13 is erected on a base 17 that is rearward in the vertical direction, an upper end portion thereof is fixed to a side surface of the main member 2, and a lower side thereof is fixed to a base member 14 fixed to the foundation 17. In order to incline the main material 2 so that the rear becomes higher, the rear pillar material 13 is configured to be longer than the front pillar material 12.

  The front base member 14 reinforces each skirt portion of the front pillar member 12 by connecting the front pillar members 12 to each other. Further, the rear base member 14 connects the rear rear pillar members 13 to each other and reinforces each skirt portion of the rear pillar member 13. The bottom of each base material 14 is fixed to each foundation 17 by anchor bolts.

  The connecting plate 15 connects the rear column member 13 and the diagonal member 16.

  The diagonal member 16 is provided obliquely with respect to the rear column member 13, an upper end portion thereof is fixed to the side surface of the main member 2, and a lower end portion thereof is fixed to the rear column member 13 via the connecting plate 15. A triangular portion having three sides of the rear column member 13, the oblique member 16, and the main member 2 is formed to reinforce the mechanical strength in the left-right direction in the drawing of the solar cell panel installation base 11.

  The foundation 17 is fixed on the flat part GL of the roof or the ground. The flat part GL of the roof or the ground is an installation surface on which the solar cell panel installation base 11 is installed.

  The process of interposing the drain cover 1 having the above configuration between the main material 2 and the solar cell panel module 3 will be described.

  FIG. 6 is a schematic diagram for explaining a process of interposing the draining cover 1 on an existing installation base.

  As shown in FIG. 6, first, in an existing installation base, the bolts 4 and nuts (not shown) that fix the main material 2 and the solar cell panel module 3 are loosened and removed (note that the draining cover 1 If the solar cell panel module 3 can be lifted from the main material 2 to the extent that can be installed, it is not necessary to remove the nut). Next, the solar cell panel module 3 on the main material 2 is floated upward from the main material 2, and the main material fitting of the draining cover 1 is performed in the width direction of the main material 2 corresponding to the gap 3 a between the solar cell panel modules 3. Insert the recess and install with one touch. Then, the adjacent both solar cell panel modules 3 are put on it (on both sides in the width direction of the flat portion 1a of the draining cover 1). Furthermore, the bolt 4 and a nut (not shown) are fastened.

  Thereby, the draining cover 1 can be interposed between the existing main material 2 and the solar cell panel module 3. Thus, without removing the solar cell panel module 3 from the main material 2, the drainage cover 1 can be installed with one touch between the solar cell panel module 3 only by floating. For this reason, the draining cover 1 can be easily added to the existing installation base other than when a new solar cell panel module is installed.

  FIG. 7 is a schematic diagram for explaining a process of interposing the draining cover 1 when a frame is newly assembled.

  In FIG. 7, the draining cover 1 is installed at a position where the gap 3 a between the solar cell panel module 3 and the solar cell panel module 3 comes on the main material 2 of the solar cell panel installation base 11. At this time, the main material fitting recess between the main material guide portions 1e of the draining cover 1 is fitted in the width direction of the main material 2 and installed. The solar cell panel module 3 is installed on them (on both sides in the width direction of the flat portion 1a of the draining cover 1), and the solar cell panel module 3 and the main material 2 are fixed with bolts and nuts.

  As described above, the draining cover 1 of the first embodiment is a long main material 2 that supports a plurality of solar cell panel modules 3, and includes a main material 2 including a region below the gap 3 a between the solar cell panel modules 3. And a planar portion 1a that is interposed between the solar cell panel modules 3 facing each other and covers at least the surface of the main material 2 exposed between the solar cell panel modules 3, and the longitudinal direction of the planar portion 1a An inclined portion (including a flat portion 1b having a triangular shape in a plan view) that leads to rainwater that has entered the flat surface portion 1a from the gap 3a between the solar cell panel modules 3 connected to both sides to a lower position away from the main material 2; A draining portion 1d composed of a tip opening for discharging or ejecting rainwater by increasing the periphery of the flat portion 1b in a triangular shape in plan view of the inclined portion and gradually narrowing the guide width into a nozzle shape; To the tip opening Cross-sectional area of the flow of water until is gradually narrowed smaller.

  Thus, the main material 2 in the gap 3a between the solar cell panel modules 3 is covered with the flat surface portion 1a of the draining cover 1, and the main material 2 is not directly exposed to rain water. Rainwater entering through the gap 3a between the solar cell panel modules 3 flows separately from the flat surface 1a of the draining cover 1 to both sides, and is inclined downward at the flat flat portion 1b in plan view to interrupt the flow of water. The area is gradually reduced. As a result, rainwater is blown from the pointed draining portion 1d of the tip opening portion (the apex of the triangular shape in plan view) of the flat portion 1b having a triangular shape in plan view and falls downward.

  Accordingly, since the flat portion 1b having a triangular shape in plan view is inclined and the periphery toward the apex thereof is bent upward to gradually narrow the guide width, rainwater is gradually collected in the center and the draining portion 1d having a thin tip. It falls down vigorously from. How much momentum depends on the amount of water, the length of the flowing direction of the draining cover 1 and the guide width, but it is characterized by the fact that draining is effectively performed regardless of the outflow speed and discharge speed of the water. is there. As a result, rainwater does not travel around the drainage portion 1d, and the main material 2 is never exposed to rainwater. Accordingly, the rust and corrosion of the main material 2 can be delayed and the rust and corrosion of the main material 2 can be more reliably suppressed. In addition, since the main drainage cover 1 is mounted on the main material 2 only by being sandwiched between the main material 2 and the solar cell panel module 3, it does not take time to attach the drainage cover 1 as in the prior art.

  In addition, in the draining cover 1 of this Embodiment 1, as shown to Fig.1 (a) as a guide part which guides the water which approachs from the clearance gap 3a between both the solar cell panel modules 2 to the position away from the main material 2. FIG. The main material region including at least the main material region in the gap 3a is sandwiched between the solar cell panel modules 3 opposed to the position of the main material 2 and includes the main material region in the gap 3a. The flat surface portion 1a having a quadrangular shape in plan view covering the surface region of the main material is provided, and flat portions 1b having a triangular shape in plan view inclined downward are provided on both sides of the flat surface portion 1a in the water guiding direction. The case where both sides of the direction perpendicular to the water guiding direction of the portion 1b are configured higher than the flat portion and the cross-sectional area of the water flow up to the draining portion 1d of the opening is gradually reduced is described. However, not limited to this, Te plan view triangular flat portion 1b which is inclined downward only in water guiding direction on one side of the flat portion 1a may be continuously provided as shown in FIG. 1 (b). Other than the draining cover 1A is the same as the draining cover 1.

  In this case, as shown in FIG. 1 (c), a steel material having no vertical wall surface on one side, such as a U-shaped steel material or a L-shaped steel material, is used as the main material 2. The drainage cover 1A is installed so that the side without the vertical wall surface corresponds to the side where the flat portion 1b is not connected to the flat portion 1a of the drainage cover 1A. It suffices that the distance from which the falling water directly falling from the flat surface portion 1a of the draining cover 1A does not wrap around the upper flat surface side of the cross-sectional U-shaped steel material or the L-shaped steel material of the main material 2 is sufficient. Thus, even if the flat portion 1b is not continuously provided on one side of the flat portion 1a, the vertical wall surface of the U-shaped cross-section steel material or the L-shaped steel material of the main material 2 is blown from the flat portion 1a by wind or the like. It is possible to prevent the falling water from hitting directly.

(Embodiment 2)
In the first embodiment, the case where the cross-sectional area of the water flow up to the opening at the end of the flat portion 1b is gradually reduced has been described, but in the second embodiment, the end of the flat portion 1b is reduced. A case where the cross-sectional area of the water flow up to the opening (outflow portion) is not gradually reduced will be described.

  8 (a) to 8 (c) are perspective views showing a schematic configuration of another example of the drainage cover of FIG. 1 in Embodiment 2 of the present invention.

  As shown in FIG. 8 (a), as the draining cover 1B of the second embodiment, flat portions 1b 'are continuously inclined at both sides (or one side) of the plane portion 1a in the water guiding direction, and inclined downward. In the flat portion 1b ', both sides in the direction perpendicular to the water guiding direction are not high, and the flat portion 1b', which is all flat, is connected from the flat portion 1a to guide water downward.

  As shown in FIG. 8 (b), as the draining cover 1C of the second embodiment, flat portions 1b ′ are continuously inclined at both sides (or one side) of the flat portion 1a in the water guiding direction, and are inclined downward. In the flat portion 1b ′, the partition portions 1b ″ that are higher than the flat portion 1b ′ on both sides in the direction perpendicular to the water guiding direction are bent upward in the vertical direction. Guides you down.

  As shown in FIG. 8 (c), as the draining cover 1D of the second embodiment, inclined recesses 1h are continuously provided inclined on both sides (or one side) of the flat surface portion 1a in the water guiding direction, and inclined downward. In the inclined recess 1h (the upper surface is a curved surface), both sides in a direction perpendicular to the water guiding direction are higher than the center.

  In the draining covers 1B to 1D, as a guide part for guiding water entering from the gap 3a between the solar cell panel modules 2 to a position away from the main material 2, the main material position including at least the main material region in the gap 3a; The flat surface portion 1a is sandwiched between the solar cell panel modules 3 facing the main material position, and the flat surface portion 1a covers the main material surface region including at least the main material region in the gap 3a. Only one of the flat portion 1b ′ inclined downward and the inclined concave portion 1h may be continuously provided on at least one side (one side) of the both sides of the plane portion 1a in the water guiding direction. As shown in the draining cover 1C of (b), partition portions 1b ″ may be formed in which both sides of the flat portion 1b ′ in the direction perpendicular to the water guiding direction rise higher than the flat portion 1b ′. In addition to the end face of the flat part 1b ', the outflow part may be an opening with the U-shaped open side up, or a U-shaped or V-shaped opening. As in the case of the cover 1 or 1A, the cross-sectional area of the water flow up to the outflow portion (opening portion) at the end of the flat portion 1b ′ is not gradually reduced, but may be slightly reduced inward. .

  Thus, the outflow part in the draining cover 1B-1D of this Embodiment 2 is flat part 1b 'and the recessed part (flat part 1b' and the flat part 1a which inclined below to at least one side of the water guide direction both sides of the plane part 1a. Any one of the partition portion 1b "and the inclined recess 1h) is connected to the tip portion thereof. The recess portion of the outflow portion has the same width along the direction of the tip portion toward the outflow portion. In addition, the recessed part of the outflow part in the draining cover 1 or 1A of the said Embodiment 1 is comprised by the front-end | tip part which the width | variety narrowed gradually along the direction to an outflow part.

(Embodiment 3)
FIG. 9 is a perspective view showing a configuration example of a main part of a drain cover in Embodiment 3 of the present invention.

  In FIG. 9, the draining cover 5 of Embodiment 3 has a bent shape in which a plate body having a predetermined development shape is folded in two. The outer dimension of the open side of the bent shape is formed wider than the gap 3 a between the solar cell panel modules 3. The folded inner surface of the water draining cover 5 is opened upward when it is inserted into the gap 3a between the solar cell panel modules 3 from the folding side to constitute the rainwater guide portion 5a. Both openings as the two-folded outflow portions of both end surfaces of the draining cover 5 in the longitudinal direction constitute draining portions 5b. Both openings of the draining portion 5b are formed in a V shape (further, the opening area of the opening may be narrowed down from both sides to reduce water). The opening area of the opening portions at both ends is set to be sufficiently small or about half of the cross-sectional area in the width direction of the gap 3a. The length of the drainage cover 5 in the longitudinal direction is sufficiently longer than the length of the main material 2 in the width direction.

  A slit-like notch 5c is formed from the side opposite to the half-folded portion of the drainer cover 5 (open side). Here, the slit-shaped cutout portion 5c is formed at one place on the left side and the front and back sides, respectively, with the folding side of the draining cover 5 facing down. On the further end face side of the slit-shaped cutout portion 5c, a spring retaining piece 5d that is bent and protrudes further outward from the bent portion is formed.

  FIG. 10 is a front view of the draining cover 5 showing how the draining cover 5 of FIG. 9 is inserted into the gap 3a between the solar cell panel modules 3 from the bent portion side. FIG. 10 is a side view of the drainage cover 5 showing a state in which the drainage cover 5 of FIG. 8 is inserted to the position of the main material 2. In addition, in FIG. 10, the main material 2 and the solar cell panel module 3 on it are shown with the virtual line (two-dot chain line).

  As shown in FIGS. 9 and 10, since the draining cover 5 does not tilt, from the bent portion 5 e side of the draining cover 5 to the position where the gap 3 a between the solar cell panel modules 3 hits the surface (flat surface) of the main material 2. insert. At this time, the gap 3a between the solar cell panel modules 3 can be completely closed without water leakage by the spring property urging the outside of the draining cover 5. As a result, rainwater that flows along the inclination of the solar cell panel module 3 enters the folded inner surface side of the drainage cover 5 from the gap 3a between the solar cell panel modules 3, and flows through the inner surface that is folded in half. It is discharged or ejected from the opening.

  Further, when the draining cover 5 is inserted from the bent side of the draining cover 5 to the position where it contacts the surface of the main material 2 in the gap 3a between the solar cell panel modules 3, as shown in FIG. Is fitted into the stepped portion on the upper end face of the solar cell panel module 3 to prevent it from coming off. Further, the upper end outer surface of the drainage cover 5 on the open side presses the inner surface (end surface) of the gap 3 a between the solar cell panel modules 3. Note that the solar cell panel module 3 may or may not have a step portion on the upper end surface in the longitudinal direction. The drainage cover 5 with the retaining pieces 5d is used for the solar cell panel module 3 having a stepped portion.

  According to the above configuration, first, rainwater that has dropped on the upper surface of the solar cell panel module 3 flows obliquely downward along the inclined surface on the solar cell panel module 3. Rainwater that has flowed obliquely downward on the upper surface of the solar cell panel module 3 flows into the gap 3 a between the solar cell panel modules 3.

  Next, rainwater that has flowed into the gap 3a enters the guide portion 5a (inner surface) from the opening side of the drain cover 5 and is discharged or ejected from the guide portion 5a through the openings at both ends, which are the drain portions 5b of the drain cover 5. And then skipped. As a result, the rainwater is blown to both sides away from the main material 2 and falls.

  As described above, according to the third embodiment, the plate body has a bent shape that is folded in two along the longitudinal direction so that the plate body can be inserted into the gap 3a in a state in which the spring property is effective. It is comprised by the inner surface of the bending-shaped board, and the draining part 5b is comprised by the longitudinal direction both ends opening part of the bending part of a board.

  As a result, the main material 2 in the gap 3 a can be covered only by inserting the draining cover 5 into the gap 3 a between the solar cell panel modules 3. For this reason, it does not require time and effort to attach the draining cover 5 as in the case of attaching a conventional guide, and can be easily and accurately attached. Moreover, the draining part 5b which comprises the front-end | tip opening part which guides the rainwater of the guide part 5a (inner surface) is provided. In this case, since the opening area of both end openings is set to be sufficiently small or about half of the cross-sectional area in the width direction of the gap 3a, rainwater is discharged or ejected from the tip opening and spills sideways in the middle. Therefore, the main material 2 is not transmitted to the main material 2 side as in the prior art, and rust and corrosion of the main material 2 due to rainwater can be more reliably suppressed.

The double-folded outer surfaces 6a of the draining cover 6 and both end surfaces 3b of the solar cell panel module 3 form a V-shaped space. Thus, when the drainage cover 6 is inserted into the gap 3a between the solar cell panel modules 3, the drainage cover 6 opens on the lower side. A rainwater guide portion is constituted by the outer surface 6a of the drainage cover 6 and both end surfaces 3b of the solar cell panel module 3, and both openings of both end surfaces in the longitudinal direction of the drainage cover 6 constitute drainage portions 6b. The opening area of the opening portions at both ends is set to be sufficiently small or about half of the cross-sectional area in the width direction of the gap 3a. The length of the drainage cover 6 in the longitudinal direction is sufficiently longer than the length of the main material 2 in the width direction. As the main material 2, a steel material having no vertical wall surface on one side, such as a U-shaped steel material or an L-shaped steel material is used.

  A central portion on the open side of the draining cover 6 is formed with a main material fitting recess 6 c that is open to the lower side of the draining cover 6. A notch 6g into which the end 2g of the main material 2 can be inserted is formed on the inner side of the main material fitting recess 6c with a predetermined depth in the longitudinal direction. The main material fitting recess 6c and the notch 6g are formed on both surfaces of the drainage cover 6, and after the upper part of the main material 2 is fitted in each main material fitting recess 6c, the main material 2 is placed in the notch 6g. An end 2g having a predetermined thickness is inserted. On both sides of each main material fitting recess 6c, a tapered portion that guides the upper portion of the main material 2 from both ends of the drainage cover 6 inward so as to serve as a guide when the upper portion of the main material 2 is fitted. 6d and 6e are formed. The taper portions 6d and 6e are tapered so as to be inclined upward from the lower end portions 6f of the both end surfaces of the draining cover 6.

  As shown in FIG. 12 (b), after the main material fitting recess 6 c of the draining cover 6 is fitted to the main material 2 in the gap 3 a between the solar cell panel modules 3, the draining cover 6 is shifted and removed. When the end 2g of the predetermined thickness of the main material 2 is further inserted into the notch 6g for stopping, the spring property that biases the outside of the draining cover 6 in the gap 3a between the solar cell panel modules 3 is provided. Both the lower surfaces 3a of the both end surfaces 3b are pressed by the two outer surfaces 6a, so that the lower ends 3c can be completely closed by the two outer surfaces 6a without water leakage.
