Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a spliced ​​BIPV photovoltaic bracket. Background Art

[0002] Photovoltaic building integration is a technology that integrates solar power generation products into buildings. By installing photovoltaic systems on the surface of buildings, such as photovoltaic tile roofs, photovoltaic skylights, etc., the photovoltaic systems absorb solar energy and convert it into electrical energy. This can not only reduce the overall outdoor temperature, but also reduce wall heat gain and indoor air-conditioning cooling load, thereby playing a role in building energy saving.

[0003] Photovoltaic brackets, when installing a photovoltaic system, are mainly divided into several steps. First, the basic bracket is installed on the roof or other designated location, and then several M-shaped support poles are installed on the basic bracket. Then, several center support poles are installed between the M-shaped support poles. Then, after installing cross arms for loading photovoltaic panels on the M-shaped support poles, the photovoltaic panels are installed on the M-shaped support poles through the cross arms. Finally, the rainproof sealing strips are installed to realize the installation of the photovoltaic system.

[0004] During the installation of existing photovoltaic brackets, after installing the basic bracket, it is also necessary to complete the M-shaped support rod and the center support rod in sequence, which is cumbersome to install. When installing the center support rod, it is also necessary to repeatedly measure the distance between the center support rod and the M-shaped support rods on both sides to ensure that it is installed in the center. If there is a deviation in the installation position, the center support rod will not be able to support the photovoltaic panel well during the subsequent installation of the photovoltaic panel, resulting in a reduced service life of the photovoltaic system.

When bolt 707 rises, the movable rod 706 and the clamping block 705 drive the cross plate 704 and the extrusion block 701 to rise, thereby driving the extrusion block 701 to squeeze and position the edge of the through groove inside the cross bar 202, thereby realizing the positioning and installation of the M-shaped support rod 1, so that there is no need to repeatedly install the fixing screws, and then another M-shaped support rod 1 is used to match the clamping block 702 with the cross bar 202 in the same steps, and then the plug rod 602 inside the installed fixing box 3 is pulled and the uninstalled M-shaped support rod 1 is slid to drive the plug rod 404 to be inserted into the installed M-shaped support rod 1, so that the plug The rod 404 is inserted into the circular hole inside the fixing box 3, and the plug-in block 605 is squeezed by the inclined surface at one end of the plug-in rod 404, so that after the plug-in rod 404 is inserted into the fixing box 3, the plug-in block 605 clamps and fixes the groove on the outer surface of the plug-in rod 404 through the action of the second spring 604, and then the plug-in rod 602 is loosened, so that the plug-in rod 602 is inserted into the circular hole inside the plug-in block 605 and the plug-in rod 602 under the action of the first spring 601 and the connecting plate 603, thereby fixing the plug-in rod 404, and then the fixing assembly 7 inside the newly installed M-shaped support rod 1 is installed and fixed through the same steps, thereby realizing the splicing of the M-shaped support rods 1. When the two M-shaped support rods 1 are plugged and assembled, the plug-in rod 404 is plugged in.

During the rotation of the rotating rod 401, the lifting rod 408 rises under the action of the limit rod 407 and the tension spring 406, and during the rotation, the moving block 402 also slides on the outer surface of the plug-in rod 404. After the lifting rod 408 rises, it drives the supporting block 403 to rise, thereby playing the role of the central support rod. There is no need to install the central support rod again, saving installation steps and improving installation efficiency. The same steps are followed for installation to finally complete the assembly of the bracket.The photovoltaic panel is installed through the cross arm 5 on the upper surface of the M-shaped support rod 1, thereby completing the erection of the photovoltaic system.
