DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] like Figure 1-6As shown, a roof double-layer photovoltaic bracket structure proposed in an embodiment of the utility model includes a base 1, a support column 2, a lifting member 3, a vertical rod 4, a limit rod 5 and a photovoltaic panel 6. The roof double-layer photovoltaic bracket structure designed in this scheme optimizes the overall structure through a coordinated design, improves the strength of the photovoltaic bracket, and reduces the deadweight of the photovoltaic bracket, reduces the load during roof installation, and improves the use effect. Through the coordinated design, the photovoltaic bracket can be installed on the roof more conveniently, reduces the number of bolts used, and improves the installation efficiency. At the same time, the overall height of the photovoltaic bracket can be adjusted according to different use conditions, and the base 1 is evenly spaced and crossed. The fork is plugged with three support columns 2, and a lifting piece 3 is rotatably connected to the support column 2. A vertical rod 4 is slidably plugged with the top of the support column 2, and a limit rod 5 is plugged with the vertical rod 4. Photovoltaic panels 6 are installed on the vertical rod 4 and the limit rod 5. During installation, the base 1 is fixed to the roof, and then the front, middle and rear support columns 2 are cross-installed in the engaging grooves 101 respectively, so that the engaging block 201 is engaged with the engaging groove 101, and then the vertical rod 4 is plugged into the connecting head 206. The vertical rod 4 can limit the plugging of the three support columns 2, so that the three cross-installed support columns 2 can be kept parallel, and the three cannot be disassembled without disassembling the vertical rod 4. The support columns 2 are disassembled for use, and the limiting rods 5 are inserted into the limiting grooves 402 and the connecting heads 206, so that the connection of the vertical rods 4 on the support columns 2 can be limited, ensuring that the vertical rods 4 cannot be disassembled without removing the limiting rods 5, and then the photovoltaic panels 6 with a parallel double-layer design are fixedly connected to the vertical rods 4 and the limiting rods 5. While ensuring a firm installation, the vertical rods 4 and the limiting rods 5 can be limited for use. By coordinating the limiting use, the photovoltaic bracket of this scheme can be assembled and fixed as a whole without using bolts, thereby meeting the use requirements and improving the efficiency of the photovoltaic bracket construction. The overall height of the support column 2 can be adjusted. When the rotating disk 302 is rotated, the screw 301 can be rotated, so that the plug-in column 205 threadedly connected to the screw 301 can slide and rise and fall inside the plug-in cavity 203, thereby realizing the adjustment of the overall height of the support column 2 to meet different installation and use conditions. The base 1, the lifting member 3, the vertical rod 4 and the limit rod 5 are all made of high-strength weather-resistant steel, and the surface is coated with water-based imitation zinc paint. The high-strength weather-resistant steel can make the photovoltaic bracket more solid and reduce its own weight. The coating of water-based imitation zinc paint can reduce the pollution generated during pickling, shot blasting and hot-dip galvanizing treatment, thereby meeting the use requirements.

[0026] like Figure 3 As shown, in some embodiments, three snap-fitting grooves 101 are cross-opened at equal intervals on the base 1. The design of the base 1 satisfies the connection and use of the bracket. The design of the snap-fitting grooves 101 enables the support column 2 to be conveniently installed and fixed, thereby improving the use effect.

[0027] like Figure 4 As shown, in some embodiments, the support column 2 is composed of a snap-fit ​​block 201, a column 202, a plug-in cavity 203, a rotating groove 204, a plug-in column 205 and a connector 206. The snap-fit ​​block 201 is slidably plugged into the snap-fit ​​groove 101, and the snap-fit ​​block 201 is integrally provided with a column 202, the column 202 is provided with a plug-in cavity 203, the bottom of the plug-in cavity 203 is provided with a rotating groove 204, the plug-in column 205 is slidably plugged into the plug-in cavity 203, and the top of the plug-in column 205 is fixedly connected with a connector 206. The design of the support column 2 meets the use requirements, can support and install the photovoltaic panel 6, and can adjust the height according to different use conditions.

[0028] like Figure 4 As shown, in some embodiments, the lifting member 3 is composed of a screw rod 301 and a rotating disk 302. The screw rod 301 is threadedly connected to the bottom of the plug-in column 205. The bottom of the screw rod 301 is fixedly connected to the rotating disk 302. The rotating disk 302 is rotatably connected in the rotating groove 204. The lifting member 3 is convenient for adjusting the overall height of the support column 2.

[0029] like Figure 5 As shown, in some embodiments, a sliding groove 401 is provided on the vertical rod 4, and limiting grooves 402 are provided on the vertical rod 4 at equal intervals. The sliding groove 401 is plug-in-coordinated with the connector 206, and the limiting groove 402 is plug-in-coordinated with the limiting rod 5. The design of the vertical rod 4 enables the photovoltaic bracket to be connected and fixed without the need for a large number of bolts during assembly, thereby improving installation efficiency.

[0030] like Figure 1 and Figure 2 As shown, in some embodiments, the base 1, the lifting member 3, the vertical rod 4 and the limit rod 5 are all made of high-strength weathering steel, and the surface is coated with water-based zinc-like paint. Through coordinated design, the strength of the bracket can be improved, the overall dead weight of the bracket can be reduced, the load-bearing load of the roof can be reduced, the anti-corrosion and anti-rust effects can be improved, and the use requirements can be met.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
