[0002] Photovoltaic brackets are supporting devices used to install and fix photovoltaic modules in solar photovoltaic power generation systems. According to different needs and application scenarios, the design and material selection of photovoltaic brackets are diverse. The design of photovoltaic brackets needs to consider the vertical bearing capacity and wind pressure bearing capacity verification, as well as the horizontal bearing capacity verification and overall stability verification of the pile foundation. The material selection and construction quality of the bracket also directly affect the bracket's wind resistance, corrosion resistance and life.

[0003] At present, the common photovoltaic bracket materials on the market include aluminum alloy (anodized), stainless steel (304), hot-dip galvanized steel, high-strength plastics, fiber-reinforced composite materials, etc. In addition, there are photovoltaic brackets made of concrete, which are mainly used in large photovoltaic power stations.

[0004] The design and installation methods of existing photovoltaic brackets also vary according to the usage scenarios. There are mainly two categories: ground brackets and roof brackets. Among them, ground brackets are a way to install photovoltaic modules on the ground, and roof brackets are a way to install photovoltaic modules on the roof of a building.

[0054] like Figure 14-Figure 21 As shown, the specific installation operation of the photovoltaic bracket of the utility model for installing the photovoltaic panel 4 is as follows:

[0055] Step 1) Install base 3:

[0056] Step 11) For rocky geology, install the rock base 31: find or chisel out a 500x500mm ground plane position on the top surface of the stone, which is hard and can firmly install the second fixing member 312. The plane inclination cannot exceed 30 degrees, and then install the rock base 31;

[0057] Step 12) For muddy geology, install the flat ground base 33, determine the installation position and complete the work of drilling metal spiral piles and pouring the flat ground base 33;

[0058] Step 13) For flat terrain such as the roof, install the flat base 33, the specific operation is as follows:

[0059] a. Determine the installation plan and location based on the actual situation such as the thickness of the floor or protective layer and the depth of the waterproof layer, and ensure that the drilling depth is carried out without damaging the waterproof layer structure. The drilling depth must be guaranteed to be more than 50mm.

[0060] b. Before installing the first fixing member 332, first pour the water-based waterproofing agent into the hole twice, and then install the first fixing member 332 and the flat base 33;

[0061] Step 2) Install support rod 1:

[0062] Step 21) Select the appropriate type and length of the support rod 1 according to the installation environment and terrain environment;

[0063] Step 22) When selecting a support rod 1 with double ball heads, it is necessary to first insert the upper and lower fastening shells of the support rod 1 into the support rod 1 according to the installation direction, and then connect the splicing ball head. When screwing in the splicing ball head, first apply high-temperature resistant AB glue on the inner wall thread of the ball head, and then screw in and tighten the splicing ball head;

[0064] Step 23) After the support rod 1 is inserted into the rock base 31, the verticality of the support rod 1 is corrected in time, and the second connecting piece 63 of the lower anchor housing is tightened with force;

[0065] Step 3) Install the universal bracket base 2:

[0066] Step 31) insert the universal bracket base 2 into the ball head structure 11 of the support rod 1, and use the first connecting member 53 to connect the ball head adjustment sleeve 21 of the universal bracket base 2 and the upper fastening shell 5 together and temporarily fix them;

[0067] Step 32) insert the movable side buckle 23 with the dovetail wing 26 and the pressing piece 25 into the frame groove 41 of the photovoltaic panel 4, and tighten the anchor screw 24 and the top screw 27 in sequence;

[0068] Step 33) Use an inclinometer to adjust the photovoltaic panel 4 bracket to a suitable position according to the required orientation and angle of the photovoltaic panel 4, and then tighten the fastening screws of the lower anchor shell to complete the installation of the photovoltaic bracket and the photovoltaic panel 4;

[0069] Step 4) Wind pressure resistance reinforcement:

[0070] Step 41) Determine whether to install a wind pressure resistant component based on local meteorological data combined with the installation ground environment and the length of the support rod 1;

[0071] Step 42) When the reinforcement and the bracket are installed simultaneously, it is best to choose the matching support rod 1 for installation. The later reinforcement can adopt the rope 8 reinforcement mode. In the rope 8 installation mode, if there is no rock or concrete as an anchoring matrix at the ground end, it is necessary to pre-embed metal spiral piles as an anchoring matrix;

[0072] Step 43) Before customizing the photovoltaic bracket, negotiate with the bracket manufacturer to insert the dovetail buckle ring into the bracket frame to improve installation efficiency. Temporary wind pressure resistance reinforcement is required, and the "self-locking dovetail buckle ring 9" needs to be used for reinforcement.
