Description

  The present invention relates to a solar cell module support structure that supports a solar cell module that photoelectrically converts sunlight, a solar cell module mount that uses the support structure, and a solar power generation system that uses the mount.

  An example of this type of solar power generation system is disclosed in Patent Document 1. Here, a plurality of crosspieces and a plurality of support members are combined in a cross-beam shape to construct a platform for solar cell modules, and a plurality of solar cell modules are bridged between each crosspiece to support each solar cell module. Yes.

  Also, fixing hooks are provided at a plurality of locations on the crosspiece, engagement recesses are formed at a plurality of locations on the solar cell module frame, and each engagement recess of the solar cell module frame is fixed on the crosspiece. The solar cell module is fixed by being hooked on a hook for easy operation.

  However, by combining a plurality of bars and a plurality of support members in a cross-beam shape, a frame is constructed, and the solar cell module itself is reinforced with a frame so that both the frame and the solar cell module have sufficient strength. However, since the strength of each solar cell module, that is, the location where there is no frame of the solar cell module is the weakest, from the viewpoint of the strength of the entire photovoltaic power generation system, the frame contributes little to improving the strength. The number of parts was unnecessarily large.

  In Patent Document 2, a solar cell module in which a plurality of support bars are bonded and fixed to the back surface of a solar cell panel, that is, a so-called frameless solar cell module is applied, and each support bar is bridged between each rail. It is fixed.

  For this reason, at least the frame of the solar battery panel can be omitted, the strength of the entire photovoltaic power generation system can be made almost dependent on the strength of the crosspieces, and the strength of the entire photovoltaic power generation system can be reasonably improved.

  However, in order to fix the end portion of the support bar to the crosspiece, a guide support, a mounting bracket, a bolt, and the like are used, and the number of parts is large.

  Furthermore, it is conceivable that the fixing hook of Patent Document 1 is applied to fix the solar cell module of Patent Document 2 and the fixing hook is hooked on the end portion of the support bar of the solar cell module. In this case, the frame, guide support, mounting bracket, bolts, etc. can be reduced, but the solar cell panel is easily bent, so if the end of the support bar is only hooked on the fixing hook, The solar panel may be damaged.

  As described above, in Patent Document 1, when viewed from the viewpoint of the strength of the entire photovoltaic power generation system, the frame hardly contributes to the strength improvement, and the number of parts is unnecessarily large. Moreover, in patent document 2, although the frame of at least a solar cell module can be omitted and the strength of the entire photovoltaic power generation system can be reasonably improved, a guide is provided to fix the end portion of the support bar to the crosspiece. Since support tools, mounting brackets, bolts, etc. were used, the number of parts was still large. Further, when the fixing hook of Patent Document 1 is applied to fix the solar cell module of Patent Document 2, even if the number of parts is reduced, the end of the support bar is only caught on the fixing hook. There was a possibility that the solar cell panel would be greatly bent and damaged by wind pressure or the like.

  In the solar cell module support structure of the present invention, the second contact portion includes a second load receiving portion facing the second convex portion with the other support member interposed therebetween.

  Next, the solar cell module mount of the present invention uses the support structure of the solar cell module of the present invention. Moreover, the solar power generation system of the present invention uses the above-described solar cell module mount of the present invention.

A water stop member (synthetic resin or the like) is interposed between the screw and the screw hole 3j.

  FIG. 8 is a perspective view showing the tilt base 11. As shown in FIG. 8, the inclined base metal 11 is inclined outwardly at an inclined plate 11a, side plates 11b bent at both ends of the inclined plate 11a, and inclined sides 11c of the side plates 11b inclined with respect to the inclined plate 11a. Each connecting plate 11d is bent, and each rectangular guide plate 11e is bent at the lower end of each connecting plate 11d. Each connecting plate 11d and each guide plate 11e are bent in a substantially V shape, and when viewed from the side of the tilt base 11, the upper end of each guide plate 11e is parallel to the inclined side 11c of each side plate 11b. The inclined plate 11a is inclined at an angle α with respect to the upper end of each guide plate 11e. Further, when viewed from the side of the inclined base metal 11, the inclined plate 11a and the end portion 11f of each side plate 11b form an angle (90 ° −α). Furthermore, a screw hole 11g is formed near the lower end of the inclined plate 11a.

  Each guide plate 11e is parallel to each other, and the outer separation distance J1 of each guide plate 11e is slightly narrower than the interval K1 (shown in FIG. 7) between the side plates 3b of the support fitting 3. Further, the height J2 of each guide plate 11e is slightly narrower than the distance K2 (shown in FIG. 7) between each rail portion 3g of the support fitting 3 and each top plate 3c. For this reason, each guide plate 11e of the inclined bracket 11 can be disposed between each side plate 3b of the support bracket 3 and between each rail portion 3g and each top plate 3c.

  FIG. 9 is a perspective view showing a state in which the inclined base metal 11 is arranged inside the support metal 3. As is clear from FIG. 9, the guide plates 11e of the inclined bracket 11 are connected between the side plates 3b of the support bracket 3 and between the rail portions 3g and the top plates 3c from one opening of the support bracket 3. , The lower end of each guide plate 11e is placed on each rail portion 3g, and the inclined bracket 11 can be moved in the longitudinal direction of the support bracket 3.

  Further, in a state where the guide plates 11e of the inclined bracket 11 are placed on the rails 3g of the support bracket 3, the guide plates 11e of the tilt bracket 11 and the side plates 3b of the support bracket 3 are arranged substantially in parallel. The upper ends of the guide plates 11e of the inclined bracket 11 and the top plates 3c of the support bracket 3 are arranged substantially parallel to each other. For this reason, the inclined base metal 11 is supported in the height direction and the horizontal direction (direction orthogonal to the side plates 3b) inside the support metal 3 with little backlash, and is inclined with respect to the top plate 3c of the support metal 3. The inclined plate 11a of the metal fitting 11 is inclined at an angle α, and the end portions 11f of the side plates 11b of the inclined base metal fitting 11 are perpendicular to the top plates 3c.

  Further, in the vicinity of one end of each side plate 3 b of the support metal 3, stoppers 3 k that protrude inside the respective side plates 3 b are formed, and each guide plate of the inclined base metal 11 inserted inside the support metal 3. When 11e hits the stopper 3k of each side plate 3b of the support metal 3, the inclined base metal 11 stops and is positioned in the longitudinal direction of the support metal 3.

  Further, the height J3 (shown in FIG. 8) of each side plate 11b of the tilt base 11 is slightly smaller than the vertical separation distance Q (shown in FIG. 6) of the bottom 4m with respect to the tilt fixing portion 4g of the cross rail 4. It is set short. Therefore, as shown in FIG. 2, each side plate 11 b of the inclined rail 11 is inserted between the inclined fixing portion 4 g and the bottom 4 m of the horizontal beam 4, and the inclined fixing portion 4 g of the horizontal beam 4 is It can be placed on the inclined plate 11a.

  FIG. 9 also shows the fixture 12. The fixture 12 includes a contact plate 12a, side plates 12b and 12c bent at both ends of the contact plate 12a, and reinforcing plates 12d bent inward at both ends of one side plate 12b. . A perforation 12e is formed in the center of the contact plate 12a. The bolt 13 is threaded into the screw hole 11g of the inclined plate 11a of the inclined bracket 11 through the washer, the perforation 12e of the fixing bracket 12, and the long hole 4n of the inclined fixing portion 4g of the horizontal rail 4 (not shown). It is concluded.

  Next, the support structure of the solar cell module 5 in the gantry 10 will be described in detail. As shown in FIG. 2, in the water flow direction A, the two support fittings 3 are arranged and fixed at respective positions where both ends of the solar cell module 5 can be placed, and stoppers 3k of the respective support fittings 3. One end in the vicinity is directed downstream in the water flow direction A.

  Each inclined base bracket 11 is movable in the water flow direction A inside each support bracket 3 and supported with little play in the height direction and the lateral direction, and is inclined with respect to each top plate 3 c of the support bracket 3. The inclined plate 11a of the base metal 11 is inclined at an angle α, and the end portions 11f of the side plates 11b of the inclined base metal 11 are perpendicular to the top plates 3c.

  In addition, since the height J3 of each side plate 11b of the inclined base bracket 11 is set slightly shorter than the vertical separation distance Q of the bottom portion 4m with respect to the inclined fixing portion 4g of the horizontal rail 4, the horizontal rail 4 The tilt bracket 11 is sandwiched between the tilt fixing portion 4g and the bottom portion 4m, the horizontal beam 4 is moved in the arrow direction B, and the tilt fixing portion 4g of the horizontal beam 4 is placed on the tilt plate 11a of the tilt bracket 11. The bottom 4 m of the horizontal rail 4 can be placed on each top plate 3 c of the support fitting 3. At this time, the inclined plate 11 a of the inclined bracket 11 is inclined at an angle α with respect to each top plate 3 c of the support bracket 3, and the inclined fixing portion 4 g is inclined at the same angle α with respect to the bottom 4 m of the horizontal rail 4. Therefore, the inclined plate 11a and the inclined fixing part 4g closely overlap each other. In addition, the end portion 11 f of each side plate 11 b of the inclined bracket 11 comes into contact with the standing portion 4 k of the horizontal beam 4, and one side of each side plate 11 b comes into contact with one end of the bottom portion 4 m of the horizontal beam 4. In this state, the bolt 13 is screwed into the screw hole 11g of the inclined plate 11a of the inclined bracket 11 through the washer, the perforation 12e of the fixing bracket 12, and the long hole 4n of the inclined fixing portion 4g of the horizontal rail 4. Then, the inclined fixing part 4g of the horizontal rail 4 is sandwiched and fixed between the contact plate 12a of the fixing bracket 12 and the inclined plate 11a of the inclined base bracket 11.

  In this way, the respective cross rails 4 are attached to the inclined base metal 11 of each support metal 3. And the solar cell module 5 is spanned and supported by each horizontal crosspiece 4. FIG. Specifically, at the end on the downstream side in the water flow direction A of the solar cell module 5, the end of the solar cell panel 6 is sandwiched between the first mounting portion 4a and the first pressing portion 4d of the horizontal rail 4, The first convex portion 4v of the horizontal rail 4 is disposed so as to enter the fitting space formed between the end portion of the solar cell panel 6 and the upper inclined portion 7a of the end portion of the support bar 7, and the end of the support bar 7 The upper inclined portion 7a of the portion is in contact with the first downward inclined portion 4f of the horizontal rail 4.

  Further, at the end of the solar cell module 5 on the upstream side in the water flow direction A, the end of the solar cell panel 6 is sandwiched between the second mounting portion 4b and the second pressing portion 4e of the horizontal rail 4 and The second convex portion 4w of the crosspiece 4 is disposed so as to enter the fitting space formed between the end portion of the solar cell panel 6 and the upper inclined portion 7a of the end portion of the support bar 7, and the end portion of the support bar 7 The upper inclined portion 7 a abuts against the second downward inclined portion 4 i of the horizontal beam 4, and the lower inclined portion 7 b of the end portion of the support bar 7 faces the second upward load receiving portion 4 j of the horizontal beam 4.

  In the gantry 10 having such a configuration, the end of the solar cell panel 6 is placed on and supported by the first placement portion 4a of the horizontal rail 4 at the downstream end of the solar cell module 5 in the water flow direction A. Yes. In addition, the first protrusion 4v of the cross rail 4 is disposed so as to enter into the fitting space formed between the end of the solar cell panel 6 and the upper inclined portion 7a of the end of the support bar 7. The upper inclined portion 7a at the end of the support bar 7 abuts on the first downward inclined portion 4f of the horizontal rail 4, and the end of the solar cell module 5 is restricted from being displaced upward. Therefore, the end of the solar cell module 5 on the downstream side in the water flow direction A is stably supported at a plurality of upper and lower portions, and there is no need for screwing or the like. Moreover, since the contact area of the 1st mounting part 4a and the 1st presser part 4d of the crosspiece 4 with respect to the edge part of the solar cell panel 6 is large, between the 1st mounting part 4a and the 1st presser part 4d, the sun The end of the battery panel 6 is stably sandwiched and supported.

  Similarly, at the end of the solar cell module 5 on the upstream side in the water flow direction A, the end of the solar cell panel 6 is mounted and supported on the second mounting portion 4 b of the horizontal rail 4. The second protrusion 4w of the horizontal rail 4 is arranged so as to enter the fitting space formed between the end portion of the solar cell panel 6 and the upper inclined portion 7a of the end portion of the support bar 7. The upper inclined portion 7a at the end of the support bar 7 abuts on the second downward inclined portion 4i of the horizontal rail 4, and the end of the solar cell module 5 is restricted from being displaced upward. Therefore, the end of the solar cell module 5 on the upstream side in the water flow direction A is stably supported at a plurality of upper and lower portions, and there is no need for screwing or the like. Moreover, since the contact area of the 2nd mounting part 4b and the 2nd holding | suppressing part 4e of the crosspiece 4 with respect to the edge part of the solar cell panel 6 is large, it is the sun between the 2nd mounting part 4b and the 2nd holding | suppressing part 4e. The end of the battery panel 6 is stably sandwiched and supported.

  Further, when the solar cell panel 6 is bent downward due to wind pressure or the like, the two support bars 7 are also bent downward, and the upper inclined portions 7 a at both ends of each support bar 7 support both ends of the solar cell module 5. It is strongly pressed by the first downward inclined portion 4f and the second downward inclined portion 4i of each horizontal rail 4 that is being operated. For this reason, the downward bending of each support bar 7 (solar cell panel 6) is suppressed, the external force by wind pressure etc. acts on both ends of the solar cell panel 6 and both ends of each support bar 7, and acts. Damage to the panel 6 is prevented. Further, since a downward load due to wind pressure or the like is received by the second upward load receiving portion 4j of the cross rail 4 through the lower inclined portion 7b of the end of each support bar 7 on the upstream side in the water flow direction A, the solar cell panel 6 The downward load directly applied to the solar cell panel 6 is reduced, and this also prevents the solar cell panel 6 from being damaged.

  Further, when the solar cell panel 6 is bent upward due to wind pressure or the like, the two support bars 7 are also bent upward, and the lower inclined portion 7b of the end of each support bar 7 on the upstream side in the water flow direction A is a horizontal rail. 4 is pressed strongly in contact with the second upward load receiving portion 4j, the upper deflection of each support bar 7 (solar cell panel 6) is suppressed, and external force due to wind pressure or the like is applied to both ends of the solar cell panel 6. In addition, the support bars 7 act in a distributed manner on the upstream end of the water flow direction A of the support bars 7 to prevent the solar cell panel 6 from being damaged.

  In addition, the inclined fixing portion 4g of the horizontal rail 4 is provided on an extension of the first downward inclined portion 4f folded downward at the outer end of the first mounting portion 4a, so that the first mounting portion of the horizontal rail 4 is provided. It is located below 4a and is in the vicinity of the boundary between the first and second mounting portions 4a and 4b. In other words, when viewed in a direction (vertical direction) perpendicular to the first and second mounting portions 4a and 4b, the distance between the load center applied to the first and second mounting portions 4a and 4b and the inclined fixing portion 4g is increased. The distance is made shorter. For this reason, for example, the end of the solar cell panel 6 is placed on one of the first and second mounting parts 4a, 4b, and an excessive load due to wind pressure or the like is applied to only one of them, Even if a moment about the longitudinal axis of the horizontal beam 4 acts on the inclined fixing portion 4g, this moment is suppressed to be small and deformation and distortion of the horizontal beam 4 are suppressed. 5 is stably supported.

  Further, not only the inclined fixing portion 4g of the horizontal beam 4 is placed and fastened on the inclined plate 11a of the inclined bracket 11, but also the end portion 11f of each side plate 11b of the inclined bracket 11 is the standing portion of the horizontal beam 4. 4k, and one side of each side plate 11b is in contact with one end of the bottom 4m of the horizontal beam 4. Therefore, the horizontal beam 4 is supported at a plurality of locations, and this also causes deformation and distortion of the horizontal beam 4 due to the moment. Is suppressed, and the horizontal rail 4 and the solar cell module 5 are supported more stably.

  In addition, since the inclined plate 11a of the inclined bracket 11 is directed obliquely upward on the outer side of the horizontal beam 4, and the inclined fixing portion 4g of the horizontal beam 4 is also directed obliquely upward on the outer side of the horizontal beam 4, the horizontal beam on the roof. The bolt 13 which fastens the 4 inclination fixing | fixed part 4g will incline to the ridge side. For this reason, the operator can perform the work of screwing the bolt 13 closer to the ridge side than the horizontal rail 4, and this work becomes easy. If the inclined plate 11a of the inclined bracket 11 and the inclined fixing portion 4g of the horizontal beam 4 are directed upward, the first mounting portion 4a of the horizontal beam 4 comes directly above the inclined fixing portion 4g. The first mounting portion 4a becomes an obstacle, and the bolt 13 is inclined toward the eaves side on the roof, so that the operation of screwing the bolt 13 becomes difficult.

  Furthermore, since the solar cell module 5 is a so-called frameless one, at least such a frame is omitted, and the strength of the entire photovoltaic power generation system is made almost dependent on the strength of the horizontal beam 4, and the entire photovoltaic power generation system is Strength can be improved reasonably. For this reason, the crosspiece 4 has a cross-sectional shape as shown in FIG. 6 to increase the cross-sectional modulus and improve the strength.

  Next, the installation procedure of the solar power generation system 1 will be described. 10 and 11 (a) and 11 (b) are diagrams showing an installation procedure of the solar power generation system 1. FIG. First, as shown in FIG. 10, a plurality of support fittings 3 are arranged and fixed on the roof. At this time, each support metal fitting 3 is arranged at each position where both ends of each solar cell module 5 can be placed, and one end of each support metal fitting 3 near the stopper 3k is located downstream in the water flow direction A. Turn. Then, the plurality of inclined mount brackets 11 are attached to the respective support brackets 3. After that, as shown in FIG. 2, each side plate 11b of the inclined bracket 11 is placed between the inclined fixing portion 4g and the bottom 4m of the horizontal beam 4 for each horizontal beam 4 in the first line, the second line, and the third line. Then, the inclined fixing portion 4g of the horizontal beam 4 is placed on the inclined plate 11a of the inclined bracket 11, and the bottom 4m of the horizontal beam 4 is placed on each top plate 3c of the support metal 3. Further, the end portions 11 f of the side plates 11 b of the inclined bracket 11 are brought into contact with the standing portion 4 k of the horizontal beam 4, and one side of each side plate 11 b is brought into contact with one end of the bottom portion 4 m of the horizontal beam 4. Furthermore, the bolt 13 is screwed into the screw hole 11g of the inclined plate 11a of the inclined bracket 11 through the washer, the perforation 12e of the fixing bracket 12, and the elongated hole 4n of the inclined fixing portion 4g of the horizontal rail 4, and fastened. An inclined fixing portion 4g of the crosspiece 4 is sandwiched and fixed between the contact plate 12a of the fixing bracket 12 and the inclined plate 11a of the inclined base bracket 11.

  Next, as shown in FIG. 11 (a), for each inclined base bracket 11 on the most downstream side (closest to the eaves) in the water flow direction A, each guide plate 11 e of the inclined base bracket 11 corresponds to each support bracket 3. It moves in the water flow direction A until it hits the stopper 3k of the side plate 3b, and the horizontal rail 4 in the first line is positioned. Then, the horizontal rail 4 of the second line is moved in the vertical direction Y on the support bracket 3 together with the inclined brackets 11, and the first presser 4 d of the horizontal rail 4 of the first line and the horizontal rail of the second line 4 between the second presser portions 4e and slightly wider than the vertical width of the solar cell panel 6, and the solar cell modules 5 in the first row are connected to the horizontal beam 4 in the first line and the horizontal beam 4 in the second line. The both ends of each solar cell panel 6 are placed on the first mounting portion 4a of the horizontal rail 4 on the first line and the second mounting portion 4b of the horizontal rail 4 on the second line.

  Furthermore, as shown in FIG. 11 (b), the horizontal beam 4 of the second line is moved in the water flow direction A on each support metal fitting 3 together with the inclined brackets 11, and the horizontal beam 4 and the second line of the first line are moved. Each solar cell panel 6 is sandwiched between the horizontal rails 4 of the eyes, and the end of each solar cell panel 6 on the downstream side in the water flow direction A is connected to the first mounting portion 4a of the first horizontal rail 4 and the first mounting portion 4a.

Plug in. At this time, as shown in FIG. 2, the sealing member 8 attached to the side end of the solar cell panel 6 is sandwiched between the side end and the boundary wall portion 4c of the horizontal rail 4 to function as a buffer material. Therefore, the side end of the solar cell panel 6 does not directly contact the boundary wall portion 4c of the horizontal rail 4, and the side end of the solar cell panel 6 is not damaged. At the same time, each support bar 7 is sandwiched between the horizontal beam 4 on the first line and the horizontal beam 4 on the second line, and the first convex portion 4v of the horizontal beam 4 on the first line is placed on the solar cell panel 6. It arrange | positions between the edge part and the upper inclination part 7a of the edge part of the downstream of the water flow direction A of the support bar 7, and the upper inclination part 7a of the edge part of each support bar 7 is made into the horizontal beam 4 of the 1st line. The second convex portion 4w of the horizontal rail 4 in the second line is brought into contact with the first downward inclined portion 4f, and the upper inclined portion of the end portion of the solar cell panel 6 and the end portion of the support bar 7 on the upstream side in the water flow direction A. It arrange | positions between the parts 7a, and the upper inclination part 7a of the edge part of each support bar 7 is contact | abutted to the 2nd downward inclination part 4i of the horizontal rail 4 of the 2nd line. As a result, the solar cell modules 5 in the first row are bridged and supported between the horizontal beam 4 on the first line and the horizontal beam 4 on the second line.

  Thereafter, similarly, the horizontal beam 4 of the third line is moved to widen the distance between the horizontal beam 4 of the second line and the horizontal beam 4 of the third line, and both end portions of the solar cell panels 6 in the second row. Is mounted on the first mounting portion 4a of the horizontal beam 4 on the second line and the second mounting portion 4b of the horizontal beam 4 on the third line, and the horizontal beam 4 on the third line is moved in the water flow direction A. Each solar cell panel 6 and each support bar 7 are sandwiched between the horizontal beam 4 on the second line and the horizontal beam 4 on the third line, and each solar cell module in the second row is interposed between these horizontal beams 4. I support 5 across.

  Finally, when the horizontal rail 4 in the third line or each tilting bracket 11 that supports the horizontal rail 4 is fixed to each support bracket 3 with screws or the like, the most downstream side of the water flow direction A (the eaves edge) The horizontal beam 4 on the first line of the first line is positioned by the stopper 3k of each support fitting 3, and the horizontal beam 4 on the third line on the most upstream side (closest to the building) in the water flow direction A is fixed. Therefore, the solar cell modules 5 in the first row and the second row and the horizontal rails 4 in the second line are positioned, and all the solar cell modules 5 are supported at the respective positions.

  In the above embodiment, the end shape of the support bar 7 as shown in FIG. 4 and the cross-sectional shape of the horizontal bar 4 as shown in FIG. The cross-sectional shape of 4 can be variously modified. FIG. 12 is a cross-sectional view showing a modified example of the horizontal rail 4. The horizontal rail 4P of this modified example is obtained by adding a first upward load receiving portion 4p facing the lower inclined portion 7b of the end portion of the support bar 7 below the first downward inclined portion 4f.
