Detailed Implementation

[0031] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] like Figures 1-8As shown, this embodiment discloses a rooftop distributed photovoltaic module, suitable for sloping roofs. Generally, sloping roofs have a ridge 102 at the upper end of the slope. The rooftop distributed photovoltaic module includes a support assembly 1 and photovoltaic components 2. The support assembly 1 includes a mounting rod 11, multiple vertical support rods 12, multiple horizontal support rods 14, multiple support frames 13, and multiple end seals 17. The mounting rod 11 is fixedly installed on the ridge 102 of the roof 101. The mounting rod 11 is installed on the ridge 102 through two fixing frames 15. The fixing frame 15 includes a base plate 151, a vertical plate 152, and a positioning cylinder 153. The end of the mounting rod 11 is provided with a first connecting plate 111, which is fixedly connected to the vertical plate 152 by screws. The rotation direction of the mounting rod 11 can be limited. The base plate 151 is fixedly installed on the ridge 102 by expansion screws. The vertical plate 152 is set perpendicular to the base plate 151. The positioning cylinder 153 is located on the vertical plate 152 facing another fixed frame 15. The positioning cylinder 153 is inserted into the end of the mounting rod 11. During installation, one fixed frame 15 needs to be fixed first, and one end of the mounting rod 11 is connected to the positioning cylinder 153 of the fixed fixed frame 15. The mounting rod 11 is provided with a first through hole 112, and the positioning cylinder 153 is provided with a third through hole 1531. After locking with bolts, the mounting rod 11 is positioned, and then the first connecting plate 111 and the vertical plate 152 are locked. The vertical support rod 12 can be installed from the unfixed end of the mounting rod 11.

[0033] Multiple vertical support rods 12 are arranged along the length of the mounting rod 11. The mounting rod 11 is provided with a second through hole 113, which is arranged along the length of the mounting rod 11. The vertical support rod 12 includes a connecting sleeve 122, which is sleeved on the mounting rod 11. The connecting sleeve 122 is provided with a strip hole 1221, which corresponds to the second through hole 113. The bolt between the connecting sleeve 122 and the mounting rod 11 passes through the strip hole 1221 and the second through hole 113 for connection. The bolt passing through the strip hole 1221 and the second through hole 113 can position the vertical support rod 12 on the mounting rod 11, and the bolt is not locked at this time.

[0034] Vertical support rods 12 extend along the slope of the roof 101. The lower ends of multiple vertical support rods 12 are connected to a support frame 13. The vertical support rods 12 are spaced apart from the slope. A second connecting plate 123 is provided at the lower end of each vertical support rod 12. The second connecting plate 123 is located on the lower end face of the vertical support rod 12. The support frame 13 includes a frame rod 131, a third connecting plate 132, and a fourth connecting plate 133. The third connecting plate 132 and the fourth connecting plate 133 are located at both ends of the frame rod 131. Connect the fourth connecting plate 133 to the second connecting plate 123, then fix the support frame 13 to the wall 103 under the eaves. After the third connecting plate 132 is positioned between itself and the wall 103, it is fixed with expansion screws to lock the rotation direction of the vertical support rod 12. After tightening the bolts at the connecting cylinder 122, the vertical support rod 12 can remain fixed. There is a gap between the vertical support rod 12 and the roof, so that photovoltaic installation can be carried out without damaging the roof.

[0035] Since the slope of the roof 101 may have different widths, and the width generally increases gradually from top to bottom, the length of multiple horizontal support rods 14 is set to gradually increase from top to bottom along the slope, and the length of two adjacent horizontal support rods 14 is the same, so that the most photovoltaic panels can be installed in the corresponding roof area.

[0036] A horizontal support rod 14 is installed on a vertical support rod 12. Multiple horizontal support rods 14 are arranged along the length of the vertical support rod 12. The vertical support rod 12 includes a rod body 121. Multiple angle irons 16 are fixedly installed on the rod body 121. The multiple angle irons 16 are arranged along the length of the rod body 121. The horizontal support rod 14 is fixedly installed on the angle irons 16 located in the same row. The horizontal support rod 14 includes a first slot 141. Parts of the angle irons 16 are inserted into the first slot 141. After the horizontal support rod 14 and the angle irons 16 are inserted, they are fixedly connected by bolts. The angle irons 16 include reinforcing ribs 161. The horizontal support rod 14 is provided with multiple second slots 142. The second slots 142 extend along the length of the horizontal support rod 14. The reinforcing ribs 161 are inserted into the second slots 142. The reinforcing ribs 161 and the second slots 142 are quickly positioned along the length of the horizontal support rod 14 during installation, making installation more convenient.

[0037] like Figure 6 , Figure 7As shown, photovoltaic components 2 are installed on horizontal support rods 14. Multiple photovoltaic components 2 are arranged along the length of the horizontal support rods 14. Each photovoltaic component 2 includes a first connecting frame 21 and a second connecting frame 22. The horizontal support rods 14 include guide bars 143. Every two horizontal support rods 14 form a group. The first connecting frame 21 and the second connecting frame 22 are correspondingly connected to the two horizontal support rods 14 in a group. The first connecting frame 21 and the second connecting frame 22 slide along the guide bars 143. The two side walls of the guide bars 143 are respectively provided with a first limiting groove 144 and a second limiting groove 145. The first connecting frame 21 includes a first guide frame 211, which is slidably connected to the guide bars 143. The inner wall of the first guide frame 211 is provided with a first insert plate 212, which is located in the first limiting groove 144. The second connecting frame 22 includes a second guide frame 221, which includes a second insert plate 222, which is located in the first slot 141. During installation, the first connecting frame 21 and the second connecting frame 22 are inserted with the corresponding transverse support rods 14, so that the first guide frame 211 and the second guide frame 221 are engaged with the two transverse support rods 14. Due to the slope, the photovoltaic component 2 can be slidably installed on the guide bar 143. When all the photovoltaic components 2 in a row are placed, the photovoltaic component 2 can be pushed to adjust its position.

[0038] The second guide frame 221 is closer to the lower end than the first guide frame 211. During installation, the photovoltaic components 2 need to be installed row by row from top to bottom. A rotating plate 223 is mounted on the second guide frame 221, located on the side of the second guide frame 221 closest to the support frame 13. The rotating plate 223 is rotatably connected to the second guide frame 221. A baffle 2231 is provided at the lower end of the rotating plate 223, which can limit the vertical movement of the guide strip 143. The rotating plate 223 can be fixedly connected to the second limiting groove 145. The rotating plate 223 has a fourth through hole 2232. When the rotating plate 223 abuts against the side wall of the guide strip 143, the fourth through hole... Hole 2232 corresponds to the second limiting groove 145. The upper and lower ends of the second limiting groove 145 are provided with multiple teeth 1451. The teeth 1451 extend along the length of the transverse support rod 14. Multiple teeth are arranged inward from the opening of the second limiting groove 145. The rotating plate 223 is equipped with a third bolt 224. The third bolt 224 passes through the fourth through hole 2232 and is fixed to the teeth. During the tightening process of the third bolt 224, its thread can be locked with the teeth 1451, and finally the rotating plate 223 is fixed on the guide bar 143, so that the second guide frame 221 can be fixedly connected to the transverse support rod 14, and the photovoltaic component 2 is fixed on the transverse support rod 14.

[0039] The ends of two adjacent transverse support rods 14 are connected by end seals 17. Due to the increased width of the slope at both ends of the transverse support rods 14, the distance between the ends and the vertical support rods 12 is relatively far. Installing end seals 17 can strengthen the structural strength of the ends of the transverse support rods 14 and play a supporting and strengthening role. The end seals 17 are sleeved with the ends of the two transverse support rods 14 and locked by the first bolt 171 and the second bolt 172. The first bolt 171 is threaded to the end seal 17 and can be continuously screwed in to abut the inner end of the first limiting groove 144. The second bolt 172 can be threaded to fix the second limiting groove 145 of the second limiting groove 145 of the other guide bar 143, making the connection of the end seals 17 more secure. The end seals 17 can seal the ends of the first limiting groove 144 and the second limiting groove 145. Even if the photovoltaic component 2 becomes loose and slides along the guide bar 143, it will not fall out of the transverse support rod 14, which can ensure safety.

[0040] This embodiment also discloses a photovoltaic module installation method, based on the above-mentioned rooftop distributed photovoltaic module, including the following steps:

[0041] S1. Install one of the fixing brackets 15 at the end of the ridge 102 of the roof 101. Fit one end of the mounting rod 11 into the positioning cylinder 153 of the fixing bracket 15 and fix it by passing bolts through the first through hole 112 of the mounting rod 11 and the third through hole 1531 of the positioning cylinder 153. Fit the connecting cylinder 122 of the multiple vertical support rods 12 onto the mounting rod 11. Fit the positioning cylinder 153 of the other fixing bracket 15 into the mounting rod 11. Then fix this fixing bracket 15 to the ridge 102.

[0042] S2. Align the connecting cylinder 122 of the multiple vertical support rods 12 with the second through hole 113 on the mounting rod 11. Pass the bolt through the strip hole 1221 of the connecting cylinder 122 and the second through hole 113 of the mounting rod 11 to achieve the axial positioning of the vertical support rod 12 on the mounting rod 11. Fix the lower end of the vertical support rod 12 to the support frame 13 with bolts. After adjusting the distance between the vertical support rod 12 and the slope, fix the support frame 13 to the wall 103 under the eaves with expansion bolts. Finally, tighten the bolts located in the connecting cylinder 122 to fix the vertical support rod 12 and the mounting rod 11.

[0043] S3. The horizontal support rod 14 is fixedly installed on the angle iron 16 of the vertical support rod 12 with bolts, so that the reinforcing rib 161 of the angle iron 16 corresponds to the second slot 142 of the horizontal support rod 14, thereby realizing the quick positioning and installation of the horizontal support rod 14 and the vertical support rod 12.

[0044] S4. Install the photovoltaic component 2 from top to bottom. The first connecting frame 21 and the second connecting frame 22 of the photovoltaic component 2 are installed on the guide strip 143 of the horizontal support rod 14. Adjust the distance between two adjacent photovoltaic components 2. After determining the position, flip the rotating plate 223 of the second connecting frame 22 and tighten the third bolt 224 to fix the photovoltaic component 2.

[0045] S5. Install end seals 17 at both ends of two adjacent transverse support rods 14 to ensure end support of the transverse support rods 14.
