Description

  The present invention relates to a fixing bracket for fixing a solar cell module to a gantry and a fixing structure of a solar cell module using the fixing bracket.

  As a fixing bracket for fixing the solar cell module to a gantry mounted on the roof, etc., the solar cell module placed adjacent to the gantry is pressed against the gantry by bolting and fixed. In the fixing bracket that can be provided, when the solar cell module is fixed to the gantry, a plurality of protrusions with sharp tips are provided at the lower end portion that presses the frame of the solar cell module. (Patent Document 1 and Patent Document 2) have been proposed in which a solar cell module can be electrically connected to each other through a fixing bracket. According to this technology, a plurality of solar cell modules can be grounded (grounded) only by attaching the ground wire to one solar cell module without attaching a ground wire to each of the plurality of solar cell modules. Can do.

  However, in the techniques of Patent Document 1 and Patent Document 2, when rainwater or the like is attached to a portion where the metal portion of the frame of the solar cell module and the protrusion of the fixing metal are in contact with each other, the solar cell module is formed of different metals. Of the frame body and the fixing bracket, the one formed of a metal having a high ionization tendency generates electrolytic corrosion that dissolves in water. And if the electric corrosion between the metal part of the frame and the projection of the fixing metal advances, the contact between the frame and the projection disappears, the electrical connection between the solar cell modules is released, and the grounding can be performed. There is a possibility that the solar cell module may be lost due to the loss.

  Therefore, in view of the above circumstances, the present invention provides a solar cell module fixing bracket capable of maintaining the ground connection of the solar cell module for a long period of time, and a solar cell module fixing structure using the fixing bracket. Is an issue.

  In order to solve the above-described problems, the fixing bracket of the solar cell module according to the present invention (hereinafter, also simply referred to as a fixing bracket) is “a flat substrate portion, a through-hole penetrating the substrate portion, A pair of flat plate-like pressing pieces projecting in the same direction at right angles from the two sides of the substrate portion between which the through-holes are located, and the tip portions of the pair of pressing pieces are parallel to the surface of the substrate portion. A pair of abutting surface portions formed on a flat surface and a sharp tip blade portion projecting in a direction away from the substrate portion than each of the pair of corresponding contact surface portions, and the tip blade portion is formed on the substrate portion. It has a pair of piercing pieces extending from each of the pair of pressing pieces so as to be elastically movable in the approaching direction, and has electrical conductivity. "

  The fixing bracket of this configuration can be used as follows when a solar cell module having a metal frame is fixed to a metal frame. In a plurality of solar cell modules mounted on the gantry, a fixing bracket is placed so as to straddle the frame of the solar cell module and the upper surface of the gantry at a portion where the solar cell modules are not adjacent to each other. In the part where the modules are adjacent to each other, the fixing metal fitting is placed so as to straddle each frame facing each other. In this state, since the fixing bracket is not pressed against the gantry, the tip blade portion protruding from the abutting surface portion abuts on the upper surface of the gantry or frame body, and there is a gap between the abutting surface portion and the gantry or frame body. Is vacant. Then, the bolt is screwed into the gantry through the through hole of the fixing bracket, and the bolt is tightened until the pair of abutting surface portions abuts the upper surface of the gantry or the frame. Thereby, the frame of the solar cell module is in a state of being pressed against the gantry by the contact surface portion of the fixing bracket, and the solar cell module can be fixed to the gantry. At this time, the tip blade portion of the piercing piece is elastically moved in the direction of the substrate portion with respect to the contact surface portion, and breaks through an insulating layer such as a coating film or an oxide film on the surface of the frame or the frame body to break the frame or frame. The solar cell module can be pierced into a metal part of the body, and the solar cell module and the gantry or the solar cell modules can be electrically connected to each other through the fixing bracket.

  It is also possible to attach the screw part of the bolt upward from the pedestal, insert the screw part into the through hole of the fixing bracket from below, and screw and tighten the nut from the upper end of the screw part. The solar cell module can be fixed.

  According to the fixing bracket of the present configuration that can be used as described above, since the tip blade portion of the piercing piece is pierced into the frame of the frame or the solar cell module while being elastically moved in the direction of the substrate portion, the sharp tip blade It is urged in the direction that the part pierces deeper. Therefore, when a solar cell module having a metal frame is fixed to a metal frame, rainwater or the like is used at a portion where the metal part of the frame or frame is in contact with the tip blade of the fixing bracket. Even if electric corrosion occurs due to adhesion, the tip blade moves further in the direction of piercing by the urging force acting on the tip blade, so that the contact between the gantry or frame and the tip blade is maintained, The electrical connection between the battery modules or the like is not released.

  By the way, in the technique of patent document 1 and patent document 2, since several protrusion is made to protrude from the lower end part of a fixing metal fitting, when a solar cell module is fixed to a mount frame with a fixing metal fitting, the whole protrusion is a solar cell module. If there is a gap between the upper surface of the frame body and the lower end of the fixing bracket without biting into the frame body, if the electrolytic corrosion between the frame body and the projections proceeds due to the attachment of rainwater, etc. There is a problem that the support is not supported and the fixing bracket does not press the frame of the solar cell module against the frame. On the other hand, the fixing bracket of this configuration includes a contact surface portion that presses the frame body against the gantry separately from the tip blade portion that pierces the frame body, so that the frame body is pressed against the gantry by the contact surface portion. By fixing the solar cell module, even if the electric corrosion progresses at the tip blade part and the contact between the tip blade part and the frame body disappears, the frame body is continuously pressed against the frame by the contact surface part. Can do. Accordingly, it is possible to suppress the deterioration over time of the fixing force of the solar cell module by the fixing bracket.

  The fixing bracket of the solar cell module according to the present invention includes, in addition to the above-described configuration, “a gap piece protruding from the substrate portion between the pair of pressing pieces including the extended surfaces of the pair of pressing pieces. It has ".

  According to the fixing bracket of this configuration, when fixing the solar cell module to the gantry, the side ends of the frame bodies of the adjacent solar cell modules are brought into contact with the gap pieces, so that the solar cell module is By fixing, the positional relationship between the frame and the fixture (tip blade portion) is defined, and the tip blade portion can be pierced at a predetermined position. Moreover, the space | interval of solar cell modules can be prescribed | regulated by making the side edge of a frame contact | abut to a gap piece, and a some solar cell module can be easily aligned and fixed to a mount frame.

  The solar cell module fixing structure according to the present invention is a solar cell module fixing structure in which the solar cell module is fixed to a gantry using the solar cell module fixing metal fitting described above. One of the contact surface portions is in contact with the frame of the solar cell module placed on the gantry, and the other contact surface portion is adjacently placed on the gantry. The frame module or the frame of the battery module is in contact with the frame, the fixing bracket is fastened to the frame by a bolt inserted through the through hole, and each of the pair of tip blades is biased downward.

  A solar cell module fixing bracket 10 according to an embodiment of the present invention and a solar cell module fixing structure using the fixing bracket 10 will be described with reference to FIGS. 1 to 6. The fixing bracket 10 of this embodiment is for fixing the solar cell module 1 to the mount 5 installed on the roof or the ground.

  The fixing bracket 10 of the present embodiment includes a rectangular plate-shaped substrate portion 11, a through-hole 12 passing through the substrate portion 11, and a pair of two sides extending in parallel with the substrate portion 11. A pair of flat plate-like pressing pieces 13 projecting in the same direction at right angles, and a pair of abutting surface portions 14 formed on the front ends of the pair of pressing pieces 13 in a plane parallel to the surface of the substrate portion 11; The pair of pressing pieces 13 has an acute-angled tip blade portion 15a protruding in a direction away from the substrate portion 11 than the pair of contact surface portions 14, and the tip blade portion 15a is elastically movable in a direction approaching the substrate portion 11. And a pair of piercing pieces 15 extending from each of them.

  The through hole 12 passes through the center of the substrate portion 11. The substrate portion 11 is rectangular, and the pair of pressing pieces 13 protrude downward from the two long sides of the substrate portion 11. The pair of pressing pieces 13 has both side end portions in the direction in which the long side of the substrate portion 11 extends, from a portion located slightly below the lower surface of the substrate portion 11 to the lower end, rather than the side end portions of the substrate portion 11. Each is recessed toward the center. Therefore, in the fixing bracket 10 of this embodiment, the length of the pair of contact surface portions 14 is shorter than the long side of the substrate portion 11.

  The piercing piece 15 is located on the side of the substrate portion 11 in the direction in which the long side of the substrate portion 11 extends from the side end portion extending vertically from the recessed portion toward the center of both end portions of the pressing piece 13. Each extends to the same position as the end portion, and extends to a position below the contact surface portion 14. That is, two piercing pieces 15 are provided on one pressing piece 13. The piercing piece 15 extends so that the vertical height increases as the distance from the pressing piece 13 increases. The piercing piece 15 extends in a right triangle shape with one apex facing downward. An acute apex directed downward from the piercing piece 15 is a tip blade portion 15a, and protrudes downward from the contact surface portion 14 as shown in FIG. 1 (d). Since this piercing piece 15 has a small width in the height direction at the base portion extending from the pressing piece 13, this portion is easily elastically deformed.

  The fixture 10 of this embodiment is formed of stainless steel. That is, the fixture 10 has conductivity.

  Next, a method of using the fixing bracket 10 of the present embodiment will be described mainly with reference to FIGS. As for the gantry 5, only the long beam member 6 on which the solar cell module 1 is placed and fixed is illustrated, and the gantry 5 installed at an inclination with respect to the ground (horizontal plane). The crosspiece member 6 is illustrated in a horizontal state.

  First, the solar cell module 1 is mainly configured by a flat plate solar cell panel 2 having solar cells and a frame 3 surrounding the outer periphery of the solar cell panel 2. The solar cell panel 2 is attached to the upper inside of the frame 3. The frame body 3 has a flange portion 3a extending from the lower end to the outside in parallel with the upper surface of the solar cell panel 2, and a standing portion 3b rising from the tip of the flange portion 3a. The frame 3 is made of an aluminum alloy extrusion mold. The frame 3 has an insulating layer 3c formed of an oxide film (anodized film) on the surface.

  The gantry 5 has a crosspiece member 6 that extends longer than one side of the solar cell module 1. The crosspiece member 6 is an aluminum alloy extrusion mold material and has an insulating layer on the surface as in the case of the frame 3 although not shown. The crosspiece 6 is installed on the roof or the ground by leg members (not shown) in a state inclined with respect to the horizontal. From the upper surface of the crosspiece member 6, the screw portion 7 a of the bolt 7 protrudes upward at an interval corresponding to the length of one side of the solar cell module 1. The bolt 7 is attached to the crosspiece member 6 by inserting the screw portion 7a from below into the attachment hole 6a of the crosspiece member 6 and tightening the nut 8 screwed from the upper end of the screw portion 7a ( (See FIG. 3 (a)). Although not shown, the crosspiece members 6 are arranged in a plurality of rows in a direction perpendicular to the paper surface of FIG. 2, and one solar cell module 1 is placed so as to straddle at least two crosspiece members 6. The

  When the solar cell module 1 is fixed to the crosspiece member 6 of the gantry 5, the solar cell module 1 is placed on the upper surface of the crosspiece member 6 at a portion between the screw portions 7 a protruding from the crosspiece member 6. Then, the screw portion 7 a is inserted from below into the through hole 12 of the fixing bracket 10 above each portion where the screw portion 7 a protrudes from the crosspiece member 6. At this time, the fixing bracket 10 is set so that the pair of contact surface portions 14 are directed downward, and the direction in which the pair of pressing pieces 13 are separated is directed to the direction in which the crosspiece member 6 extends.

  In a portion where the screw portion 7 a protrudes from the crosspiece member 6, the portion where the solar cell modules 1 are not adjacent to each other extends across the flange portion 3 a of the frame 3 of the solar cell module 1 and the top surface of the crosspiece member 6. The fixture 10 is placed. That is, among the pair of pressing pieces 13 of the fixing bracket 10, the tip blade portion 15 a of the piercing piece 15 extending from one pressing piece 13 is placed on the upper surface of the flange portion 3 a of the frame 3, and the other pressing piece 13 is pressed. The tip blade portion 15 a of the piercing piece 15 extending from the piece 13 is placed on the upper surface of the crosspiece member 6. In this state, each of the pair of contact surface portions 14 is spaced upward from the upper surface of the flange portion 3 a and the upper surface of the crosspiece member 6, and there is a gap between the flange portion 3 a and the crosspiece member 6. .

  On the other hand, in the part where the screw part 7a protrudes from the crosspiece member 6, the fixing metal fitting 10 is placed so as to straddle the frame bodies 3 facing each other in the part where the solar cell modules 1 are adjacent to each other. . That is, of the pair of pressing pieces 13 of the fixing bracket 10, the piercing piece 15 extending from the one fixing piece 13 is placed on the upper surface of the flange portion 3 a of the frame 3 of the adjacent solar cell module 1. The piercing piece 15 extending from the other pressing piece 13 is placed on the upper surface of the flange portion 3a of the frame body 3 of the other adjacent solar cell module 1. In this state, each of the pair of contact surface portions 14 is spaced upward from the upper surface of the flange portion 3a, and a gap is left between the flange portion 3a.

  The fixture 10 protrudes upward from the upper surface of the substrate portion 11 through the through hole 12 of the fixture 10 in a state where the fixture 10 is placed on the upper surface of the crosspiece member 6 or the upper surface of the flange portion 3 a of the frame 3 in the solar cell module 1. The nut 20 is screwed into the threaded portion 7a. A flat washer 21 and a spring washer 22 are interposed between the substrate portion 11 and the nut 20. Then, the nut 20 is tightened so that the pair of abutment surface portions 14 of the fixture 10 abut on the upper surface of the crosspiece member 6 or the upper surface of the flange portion 3 a of the frame body 3. As a result, the frame 3 of the solar cell module 1 is pressed against the crosspiece member 6 by the contact surface portion 14 of the fixing bracket 10, and the solar cell module 1 is fixed to the crosspiece member 6.

  When the solar cell module 1 is fixed to the crosspiece member 6 by the fixing bracket 10, the tip blade portion 15 a approaches the substrate portion 11 as the contact surface portion 14 approaches the upper surface of the flange portion 3 a by tightening the nut 20. The base portion of the piercing piece 15 is elastically deformed so as to move in the direction (upward), and the urging force in the direction of piercing the flange portion 3a acting on the tip blade portion 15a increases. When the abutment surface portion 14 further approaches the upper surface of the flange portion 3a by tightening the nut 20, the sharp tip blade portion 15a breaks through the insulating layer 3c on the surface of the flange portion 3a by the increased urging force, and the frame 3 Pierce the metal part. Thereafter, the abutting surface portion 14 abuts on the upper surface of the flange portion 3 a, and the flange portion 3 a is pressed and fixed to the crosspiece member 6. In the state in which the frame 3 is fixed to the crosspiece member 6 by the fixing bracket 10, the base portion of the piercing piece 15 is elastically deformed, so that the tip blade portion 15 a is pierced deeper by the restoring force of the elastic deformation. Is biased in the direction.

  Even at the portion in contact with the upper surface of the crosspiece member 6, in the same state as described above, the acute-angle tip blade portion 15a penetrates the insulating layer on the upper surface of the crosspiece member 6 and pierces the metal portion. Thereby, the solar cell module 1, the crosspiece member 6, and the adjacent solar cell modules 1 are electrically connected to each other via the fixing bracket 10. Thereafter, the ground wire is attached to the gantry 5 or one of the plurality of solar cell modules 1 so that the whole can be grounded.

  In the present embodiment, the following fixing structure of the solar cell module 1 is formed by using the fixing bracket 10. That is, one of the pair of contact surface portions 14 of the fixing bracket 10 is in contact with the flange portion 3 a of the frame 3 of the solar cell module 1 placed on the crosspiece member 6 of the mount 5, and the other The contact surface portion 14 is in contact with the flange portion 3 a of the frame body 3 of the solar cell module 1 that is mounted on the crosspiece member 6 adjacently or the crosspiece member 6 of the mount 5, and the fixing bracket 10 is inserted into the through hole 12. It is fastened to the crosspiece member 6 of the gantry 5 by the bolt 7 inserted, and the flange portion 3a of the frame 3 or the crosspiece member 6 of the gantry 5 in a state where each of the pair of tip blade portions 15a is biased downward. It is the fixed structure of the solar cell module pierced in.

  Thus, according to the fixture 10 of the present embodiment, the top blade portion 15a of the piercing piece 15 is elastically moved in the direction of the substrate portion 11, and the top surface of the crosspiece member 6 of the gantry 5 or the solar cell module 1. Since it is stabbed into the upper surface of the flange part 3a of the frame 3, the tip blade part 15a is urged in a direction to stab deeper by the restoring force of elastic deformation during elastic movement. Therefore, even if the metal portion of the crosspiece member 6 or the frame 3 and the tip blade portion 15a of the fixing bracket 10 are in contact with each other, even if electric corrosion occurs due to adhesion of rainwater or the like and is eluted, the tip blade portion 15a. Since the leading edge 15a moves further in the direction of piercing so that the leading edge 15a is in the position indicated by the two-dot chain line in FIG. 4 due to the urging force acting on the cross member 6, the frame member 3 and the leading edge 15a The contact is maintained, and the electrical connection between the crosspiece member 6 and the solar cell module 1 or between the adjacent solar cell modules 1 is not released. Therefore, the ground connection of the solar cell module 1 fixed to the gantry 5 can be maintained for a long time.

  Further, apart from the tip blade portion 15 a that pierces the flange portion 3 a or the like of the frame body 3, the contact surface portion 14 is brought into contact with the flange portion 3 a or the crosspiece member 6, and the flange portion 3 a is pressed against the crosspiece member 6. For this reason, even if electric corrosion progresses at the tip blade portion 15a and contact between the tip blade portion 15a and the flange portion 3a is lost, the flange portion 3a is pressed against the crosspiece member 6 by the contact surface portion 14 of the fixing bracket 10. Can continue. Accordingly, it is possible to suppress the deterioration over time of the fixing force of the solar cell module 1 by the fixing bracket 10.

  In addition, in the fixture 10 of the said embodiment, since each height from the board | substrate part 11 to a pair of contact surface part 14 is the same, as shown to Fig.6 (a) etc., solar cell modules 1 mutually If it uses for the site | part which is not adjacent, the board | substrate part 11 will be in the state inclined with respect to the upper surface of the crosspiece member 6. FIG. Therefore, a fixing bracket 10B as shown in FIG. The fixing bracket 10 </ b> B projects one of the pair of pressing pieces 13 longer than the other pressing piece 13 by the thickness of the flange portion 3 a of the frame 3. That is, the heights from the substrate portion 11 to the pair of contact surface portions 14 are made different. The fixing bracket 10 </ b> B is used so that the contact surface portion 14 on the pressing piece 13 side that protrudes long is in contact with the upper surface of the crosspiece member 6, so that the substrate portion 11 is parallel to the upper surface of the crosspiece member 6. It becomes a state. Accordingly, the contact area between the substrate portion 11 and the nut 20 increases, so that the nut 20 is difficult to loosen.
