Description

[Technical Field]

[0001] The present invention relates to a mounting bracket used when mounting a solar power generation panel to a solar power generation panel mounting stand. [Background technology]

[0002] Most solar panels are constructed by sandwiching multiple arrays of cells between materials such as resin or tempered glass, and reinforcing the perimeter with a metal frame. These solar panels are mounted on a solar panel mounting frame, which consists of support piles driven into the ground and connected to crosspieces arranged in a grid pattern.

[0003] When attaching such a solar panel to a solar panel installation frame, a clamp-type mounting bracket is generally used, which presses the frame of the solar panel against the crosspiece of the frame from above, as disclosed in Patent Documents 1 and 2, for example. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-132120 [Patent Document 2] Japanese Patent Application Publication No. 2018-064331 Summary of the Invention [Problem to be solved by the invention]

[0005] Conventional clamp-type mounting brackets are designed to be positioned directly above the slats. For example, the mounting bracket described in Patent Document 1 is designed to secure a solar panel to the slats of a mounting frame by inserting a bolt head into a groove on the central axis of the top surface of the slat and tightening a nut from above. The mounting bracket described in Patent Document 2 is designed to secure a solar panel to the slats of a mounting frame by inserting a clamp nut into a groove on the central axis of the top surface of the slat and tightening a bolt from above. However, this type of mounting bracket requires work to be performed from the solar panel side, making it impossible to perform installation work from the slat side of the mounting frame. As a result, when installing solar panels on a tall mounting frame, such as an agricultural solar system, it is necessary to set up high scaffolding, which reduces the efficiency of the installation work.

[0006] The present invention has been made in view of the above-mentioned circumstances, and has as its object to provide a mounting bracket that is easy to use when mounting a solar power generation panel to a solar power generation panel mounting stand. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the present invention provides a mounting bracket for attaching a solar power generation panel to a batten of a mounting base, comprising: a fastening member; a clamp member provided with a batten abutment portion that can abut against the batten and a through hole through which the fastening member can be inserted; and a clamp nut member provided with a frame abutment portion that can abut against a frame surrounding the outer periphery of the solar power generation panel and a fastening hole through which the fastening member can be inserted and screwed, and characterized in that the fastening member is configured to be inserted from the underside of the clamp member (Invention 1).

[0008] According to this invention (Invention 1), the crosspiece abutment portion of the clamp member is abutted against the crosspiece, and the frame abutment portion of the clamp nut member is abutted against the frame of the solar panel, and then the fastening member can be inserted from the crosspiece side to perform the fastening work. Therefore, even when attaching a solar panel to a tall mounting base such as an agricultural solar panel, the fastening work can be performed from the crosspiece side of the mounting base, improving work efficiency.

[0009] In the above invention (Invention 1), it is preferable that the crosspiece abutment portion can abut from below against the upper flange portion extending outward at the top of the crosspiece, and that the frame abutment portion can abut against the frame from above (Invention 2).

[0010] According to this invention (Invention 2), the fastening operation of inserting the fastening member from the crosspiece side can be performed reliably and easily.

[0011] In the above inventions (Inventions 1 and 2), when the two adjacent solar power generation panels are defined as a first solar power generation panel and a second solar power generation panel, respectively, it is preferable that the clamp nut member has a first abutment portion that can abut against the side surface of the frame of the first solar power generation panel, and a second abutment portion that can abut against the side surface of the frame of the second solar power generation panel (Invention 3).

[0012] According to this invention (Invention 3), an appropriate distance can be secured between two adjacent photovoltaic panels.

[0013] In the above inventions (Inventions 1-3), when the two adjacent solar power generation panels are defined as a first solar power generation panel and a second solar power generation panel, respectively, it is preferable that the frame abutment portion can abut only against either the frame of the first solar power generation panel or the frame of the second solar power generation panel (Invention 4).

[0014] According to this invention (Invention 4), the mounting bracket can be used in the same way for solar panels at the edge where there are no adjacent solar panels. Therefore, there is no need to prepare separate mounting brackets specifically for solar panels at the edge. Also, unlike conventional panel clamps, when replacing one of two adjacent solar panels, there is no need to remove the other panel at the same time. This improves work efficiency.

[0015] In the above inventions (Inventions 1-4), it is preferable that the clamp nut member has a first flat portion in which the fastening hole is provided, a first vertical portion extending vertically upward from one end of the first flat portion, a second vertical portion extending vertically downward from the other end of the first flat portion, and a second flat portion extending horizontally from the upper end of the first vertical portion in the opposite direction to the extension of the first flat portion, and that the second flat portion constitutes the frame abutment portion, the first vertical portion constitutes the first abutment portion, and the second vertical portion constitutes the second abutment portion (Invention 5).

[0016] According to this invention (Invention 5), the solar power generation panel can be stably attached to the crosspiece of the mounting frame.

[0017] In the above inventions (Inventions 1-5), when the corner between the first planar portion and the first vertical portion is defined as a first corner, and the corner between the first planar portion and the second vertical portion is defined as a second corner, it is preferable that the first corner and the second corner are chamfered (Invention 6).

[0018] According to this invention (Invention 6), tilting the mounting bracket reduces the horizontal distance between the first contact portion and the second contact portion, making it easier to insert the mounting bracket between two adjacent photovoltaic panels.

[0019] In the above invention (Invention 6), when defining an opposing plane defined by the distance between the first vertical portion and the second vertical portion, it is preferable that the clamp nut member has a shape such that the entire clamp nut member can be contained within the space separated by the opposing plane by tilting the clamp nut member (Invention 7).

[0020] According to this invention (Invention 7), it is possible to remove the clamp nut member downward from between the first solar power generation panel and the second solar power generation panel, or to insert the clamp nut member from below. [Effects of the Invention]

[0021] With the mounting bracket of the present invention, the batten abutment portion of the clamp member is brought into contact with the batten, and the frame abutment portion of the clamp nut member is brought into contact with the frame of the solar panel, and then the fastening member is inserted from the batten side to perform the fastening work. Therefore, even when mounting a solar panel on a tall mounting frame such as an agricultural solar panel, the fastening work can be performed from the batten side of the mounting frame, improving work efficiency. In this way, the mounting bracket of the present invention is extremely easy to use when mounting a solar panel to a solar panel installation frame. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0023] Hereinafter, embodiments of the mounting bracket according to the present invention will be described with reference to the accompanying drawings. The embodiments described below are intended to facilitate understanding of the present invention and are not intended to limit the present invention in any way.

[0024] [Mounting bracket] Fig. 1 is an exploded perspective view showing a mounting bracket 10 according to one embodiment of the present invention. Fig. 2 is a perspective view showing the mounting bracket 10. Figs. 4A to 4D are a plan view, a bottom view, a side view, and a perspective view from the rear side of the mounting bracket 10, respectively. The mounting bracket 10 is used to attach a solar power generation panel 5 (hereinafter simply referred to as "panel 5") to a crosspiece 7 of a solar power generation panel installation stand 6 (hereinafter simply referred to as "stand 6").

[0025] The mounting bracket 10 comprises a fastening member 1, a clamp member 2, and a clamp nut member 3. The clamp member 2 is provided with a crosspiece abutment portion 21 that can abut against the crosspiece 7, and a through hole 22 through which the fastening member 1 can be inserted. The clamp nut member 3 is provided with a frame abutment portion 31 that can abut against a frame 51 that surrounds the outer periphery of the panel 5, and a fastening hole 32 through which the fastening member 1 can be inserted and screwed. The fastening member 1 is configured so that it can be inserted into the clamp member 2 from below.

[0026] 3 is an enlarged perspective view showing the panel 5 attached to the mounting base 6 using the mounting bracket 10. The panel 5 can be attached to the crosspiece 7 by inserting the fastening member 1 from below the clamp member 2 through the through hole 22 of the clamp member 2 and the fastening hole 32 of the clamp nut member 3 and screwing it into the fastening hole 32. Specifically, by fastening the fastening member 1, the frame 51 is pressed downward by the frame abutment portion 31 of the clamp nut member 3. As a result, the frame 51 and the crosspiece 7 are sandwiched and fixed between the frame abutment portion 31 and the crosspiece abutment portion 21.

[0027] (Fastening member) The structure of the fastening member 1 is not particularly limited as long as it can be inserted from below the clamp member 2 through the through hole 22 of the clamp member 2 and the fastening hole 32 of the clamp nut member 3 and can be screwed into the fastening hole 32. An example of the fastening member 1 is a bolt. FIG. 1 shows a case where the fastening member 1 is a bolt. In FIG. 1, the fastening member 1 is a so-called hexagonal socket bolt made of stainless steel, and has a cylindrical shank 11 with a thread formed on its outer circumferential surface, and a cylindrical head 12. A thread is formed on the outer circumferential surface of the shank 11. A hexagonal hole is formed in the head 12.

[0028] (clamping member) The clamp member 2 has a plate shape that is generally rectangular in plan view. The crosspiece abutting portion 21 is configured to be able to abut from below against an upper flange portion 71 that extends outward from the upper portion of the crosspiece 7. As shown in FIG. 3 , if the upper flange portion 71 of the crosspiece 7 has a turned portion 72 that extends generally downward at its tip, the crosspiece abutting portion 21 may have a fitting groove 211 that fits into the turned portion 7. In this embodiment, the crosspiece abutting portion 21 has the fitting groove 211. The fitting groove 211 is provided along one side of the clamp member 2. The through hole 22 has a circular shape in plan view. The through hole 22 is provided on the side closer to the crosspiece abutting portion 21 with respect to the center of the clamp member 2 in plan view.

[0029] There is no particular limitation on the material of the clamp member 2. In this embodiment, the clamp member 2 is made of an aluminum alloy. The clamp member 2 may be made of another metal, such as stainless steel, as long as it has sufficient strength and durability to be used as a metal fitting for mounting the panel 5 to the mounting base 6.

[0030] The clamp member 2 may have raised portions 44a and 44b on its upper surface, facing each other in a plan view. The raised portions 44a and 44b are each formed from the upper surface of the clamp member 2 toward the clamp nut member 3. Each raised portion 44a, 44b is composed of a quadrilateral-shaped raised base portion and multiple triangular pointed portions. In this case, the clamp member 2 is preferably made of a conductive metal. When the panel 5 is attached to the crosspiece 7 using the mounting bracket 10, the raised portions 44a and 44b press against the back side of the frame 51 of the panel 5, damaging the insulating layer on the surface of the frame 51, thereby establishing electrical continuity between the panel 5 and the clamp member 2. Since the raised portions 44a and 44b thus function as earth plates, a separate earth plate is not required.

[0031] The rising portions 44a and 44b may be formed by a separate member, i.e., an earth plate, that can be sandwiched between the clamp member 2 and the clamp nut member 3. In this embodiment, the rising portions 44a and 44b are formed by the earth plate 4. The earth plate 4 is manufactured by stamping and bending a conductive thin metal plate. The material of the earth plate 4 may be any conductive metal, and it is preferable to use an iron alloy material, plated steel sheet, stainless steel material, or the like, taking into consideration ease of processing and weather resistance.

[0032] The earth plate 4 has a rectangular flat base 41, and both ends of the base 41 are bent to form engaging portions 42 for engaging with both ends of the clamp member 2.

[0033] The base 41 of the earth plate 4 is provided with a circular through-hole 43 through which the fastening member 1 can be inserted. The through-hole 43 is provided in the center of the base 41 in a plan view. The through-hole 43 is positioned so as to overlap with the through-hole 22 of the clamping member 2 and the fastening hole 32 of the clamping nut member 3 when the earth plate 4 is sandwiched between the clamping member 2 and the clamping nut member 3.

[0034] The rising portions 44a and 44b are arranged on the base 41 of the earth plate 4 between the through hole 43 and the engaging portion 42 so as to face each other in a plan view. The rising portions 44a and 44b are each formed by raising a portion of the base 41 of the earth plate 4 from the top surface of the earth plate 4 toward the clamp nut member 3. When the panel 5 is attached to the crosspiece 7 using the mounting bracket 10, the rising portions 44a and 44b are pressed against the back side of the frame 51 of the panel 5, damaging the insulating layer on the surface of the frame 51, thereby establishing electrical continuity between the panel 5 and the earth plate 4.

[0035] (clamp nut material) The clamp nut member 3 has a width dimension greater than that of the clamp member 2 in plan view. In this embodiment, the width dimension refers to the longitudinal direction of the frame 51 when the mounting bracket 10 is attached to the frame 51 and the crosspiece 7. That is, in the clamp nut member 3, the width dimension refers to the longitudinal direction of the frame abutment portion 31. The fastening hole 32 has a perfect circular shape in plan view and is located in the center of the clamp nut member 3 in plan view. The inner circumferential surface of the fastening hole 32 is formed with threads that correspond to the threads formed on the outer circumferential surface of the shank 11 of the bolt serving as the fastening member 1. With this structure, when the mounting bracket 10 is attached to the frame 51 and the crosspiece 7, the clamp nut member 3 has a protruding portion 39 that protrudes further toward the center of the crosspiece 7 than the clamp member 2 in plan view. The protruding portion 39 and the clamp member 2 sandwich the upper flange portion 71 of the crosspiece 7 from above and below, thereby stably fixing the panel 5.

[0036] In the clamp nut member 3, the frame abutment portion 31 is configured so as to be able to abut against the frame 5 from above.

[0037] As shown in Figure 5, two adjacent panels 5 are defined as a first panel 5a and a second panel 5b. The clamp nut member 3 has a first contact portion 33 that can contact the side surface of the frame 51a of the first panel 5a, and a second contact portion 34 that can contact the side surface of the frame 51b of the second panel 5b. The first contact portion 33 and the second contact portion 34 have a planar shape. The first contact portion 33 and the second contact portion 34 ensure an appropriate distance between the adjacent first panel 5a and second panel 5b.

[0038] The frame abutment portion 31 is configured so that it can abut only against either the frame 51a of the first panel 5a or the frame 51b of the second panel 5b. This structure allows the mounting bracket 10 to be used in the same way on end panels 5 that do not have adjacent panels 5, eliminating the need to prepare separate mounting brackets specifically for end panels 5. Furthermore, unlike conventional panel clamps, when replacing one of two adjacent panels 5, it is not necessary to remove the other panel 5 as well, improving work efficiency.

[0039] The clamp nut member 3 has a first flat portion 35, a first vertical portion 36, a second vertical portion 37, and a second flat portion 38. The first flat portion 35 has a fastening hole 32 formed therein. The first vertical portion 36 extends vertically upward from one end 351 of the first flat portion 35. The second vertical portion 37 extends vertically downward from the other end 352 of the first flat portion 35. The second flat portion 38 extends horizontally from an upper end 361 of the first vertical portion 36 in the opposite direction to the extension direction of the first flat portion 35. The second flat portion 38 constitutes the frame abutment portion 31. The first vertical portion 36 constitutes the first abutment portion 33. The second vertical portion 37 constitutes the second abutment portion 34.

[0040] The corner between the first flat portion 35 and the first vertical portion 36 is defined as a first corner, and the corner between the first flat portion 35 and the second vertical portion 37 is defined as a second corner. The first corner corresponds to end 351, and the second corner corresponds to end 352. The first corner and the second corner are chamfered. FIG. 5 is a side view showing a method of mounting a panel 5 using a mounting bracket 10. (a) shows the state in which the mounting bracket 10 is being inserted between two adjacent panels 5a and 5b, (b) shows the state in which the mounting bracket 10 has been further inserted, and (c) shows the state in which the mounting bracket 10 has been attached. As shown in FIG. 5, when the first corner and the second corner are chamfered, tilting the mounting bracket 10 reduces the horizontal distance between the first abutment portion 33 and the second abutment portion 34, making it easier to insert the mounting bracket 10 between the two adjacent panels 5a and 5b. Furthermore, when defining an opposing plane defined by the distance between the first vertical portion 36 and the second vertical portion 37, the clamp nut member 3 has a shape that allows the entire clamp nut member 3 to fit within the space separated by the opposing plane by tilting the clamp nut member 3. Therefore, as shown in Figure 5(a), tilting the clamp nut member 3 allows the entire clamp nut member 3 to fit between the first panel 5a and the second panel 5b, making it possible to remove the clamp nut member 3 downward from between the first panel 5a and the second panel 5b or insert the clamp nut member 3 from below.

[0041] Mounting bracket 10 is configured so that, when clamp member 2 and clamp nut member 3 are fastened together by fastening member 1, one side of clamp member 2 on which crosspiece abutment portion 21 is provided and one side of clamp nut member 3 on which frame abutment portion 31 is provided are perpendicular to each other in a plan view. As a result, mounting bracket 10 of this embodiment has a shape suitable for use when crosspiece 7 of frame 6 and frame 51 of panel 5 are arranged so that they intersect, with the intersection being used as the mounting position.

[0042] [Installation method using mounting brackets] A method for attaching the panels 5 (first panel 5a and second panel 5b) to the crosspieces 7 of the mount 6 using the mounting bracket 10 described above will be further described with reference to FIG.

[0043] The panel 5 has a structure in which multiple arranged cells are sandwiched between resin or tempered glass, and the outer periphery is reinforced with an aluminum alloy frame 51. The surface of the frame 51 is treated with insulating anodized aluminum to prevent deterioration of the appearance.

[0044] The mounting base 6 has a structure in which crosspieces 7 arranged in a grid pattern are connected to the top of support piles driven into the ground. Of the multiple crosspieces 7 arranged in a grid pattern, the crosspiece located on the top, called the upper crosspiece, is defined as crosspiece 75, and the crosspiece located on the bottom, called crosspiece 76. The panel 5 is attached to the top surface of the crosspiece 75.

[0045] As shown in Figure 6(a), when the first panel 5a is placed on the upper surface of the crosspiece 75 of the mount 6, the position where the frame 51a of the first panel 5a intersects with the crosspiece 75 is the mounting position using the mounting bracket 10. The same is true for the second panel 5b and subsequent panels. In Figures 6(a) and (b), the mounting position for the first panel 5a is indicated by a solid circle, and the mounting position for the second panel 5b is indicated by a dashed circle.

[0046] 6(a), the first panel 5a is attached in a temporary fastening state to the upper surface of the crosspiece 75. Specifically, the clamp member 2 is engaged with the crosspiece 75 by fitting the fitting groove 211 of the crosspiece abutting portion 21 of the clamp member 2 into the return portion 72 at the tip of the upper flange portion 71 that extends outward from the top of the crosspiece 75.

[0047] In this state, the clamp nut member 3 is placed so that the frame contact portion 31 contacts the upper surface of the frame 51a, and the fastening member 1 is temporarily fastened (see FIG. 5(c)). When placing the clamp nut member 3, the first contact portion 33 and the second contact portion 34 are placed so that they contact the side surfaces of the frames 51a and 51b of the adjacent first panel 5a and second panel 5b, respectively.

[0048] When attaching the panel 5 to the crosspiece 75 at multiple locations, the same procedure is carried out at each attachment position, and the first panel 5a is attached to the crosspiece 75 in a temporarily fastened state using multiple mounting fixtures 10.

[0049] After all of the mounting brackets 10 have been temporarily fastened, the bolts serving as fastening members 1 are tightened one by one in order with a specified torque to fix the first panel 5a to the crosspiece 75. At this time, the rising portions 43a, 43b abutting the underside of the frame 51a are pressed against the frame 51a, damaging the insulating anodized aluminum layer, and the multiple panels 5 attached to the frame 6 become conductive to each other.

[0050] Next, as shown in Fig. 6(b), the second panel 5b is attached to the upper surface of the crosspiece 75 in the same manner as the first panel 5a. However, when the clamp nut member 3 is positioned, the first abutment portion 33 and the second abutment portion 34 are positioned so as to abut against the side surfaces of the frames 51b and 51a of the adjacent second panel 5b and first panel 5a, respectively.

[0051] In the same manner, a plurality of panels 5 are attached to the crosspieces 75 as shown in FIG. 6(c).

[0052] Figure 6(d) shows the state in which only one panel 5 has been removed. In this way, with the mounting bracket 10, the frame abutment portion 31 is configured to be able to abut against only one of the two adjacent panels 5, so unlike conventional panel clamps, when replacing one of the two adjacent panels 5, it is not necessary to remove the other panel 5 as well. Furthermore, since the mounting bracket 10 can be used in the same way for an end panel 5 that does not have an adjacent panel 5, there is no need to prepare a separate mounting bracket specifically for the end panel 5.

[0053] As described above, with the mounting bracket 10 of this embodiment, the crosspiece abutment portion 21 of the clamp member 2 is abutted against the crosspiece 75, and the frame abutment portion 31 of the clamp nut member 3 is abutted against the frame 51 of the panel 5, and then the fastening member 1 is inserted from the crosspiece 75 side to perform the fastening work. Therefore, even when attaching a panel 5 to a tall mounting base 6 such as an agricultural solar panel, the fastening work can be performed from the crosspiece 75 side, improving work efficiency. In this way, the mounting bracket 10 offers excellent workability when attaching a panel 5 to a mounting base 6.

[0054] Furthermore, with the mounting bracket 1 of this embodiment, the clamp member 3 can be fitted to the crosspiece 75 over a wide area rather than at a pinpoint, and the clamp nut member 3 can be brought into contact with the frame 51 over a wide area rather than at a pinpoint to clamp the frame 51. This allows the panel 5 to be stably attached to the mounting base 6.

[0055] On the end panels 5, up to two mounting brackets 10 can be used at the mounting positions. Specifically, in addition to the positions where mounting brackets 10 are used, mounting brackets 10 can also be used at the positions indicated by "P" on the opposite side of the crosspiece 75, as shown in Figure 3. In this case, it goes without saying that the mounting brackets 10 have a symmetrical structure with respect to the structure shown in Figures 1 to 4, with the vertical plane passing through the longitudinal centerline of the crosspiece 75 as the plane of symmetry. By using two mounting brackets 10 to attach the panel 5 to the crosspiece 75, the mounting strength can be increased, thereby improving durability against heavy loads such as snow accumulation and strong winds.

[0056] The above-described embodiments have been described to facilitate understanding of the present invention, and are not intended to limit the present invention. Therefore, each element disclosed in the above embodiments is intended to include all design modifications and equivalents that fall within the technical scope of the present invention.

[0057] Mounting bracket 10 may be electrically conductive using other members rather than using earth plate 4. The shapes of rising portions 44a and 44b may be changed as appropriate depending on the overall shape of mounting bracket 10. Furthermore, mounting bracket 10 may not be provided with any rising portions such as rising portions 44a and 44b, and may not be provided with any electrically conductive function. [Industrial Applicability]

[0058] The mounting bracket according to the present invention is extremely effective in improving the workability when mounting a solar power generation panel to a solar power generation panel mounting stand. [Explanation of symbols]
