Background

At present, most photovoltaic supports in the market are made of Q235 or Q345 steel, the steel consumption of single-pile supports is 32-35 tons/MW, hot-dip galvanizing or aluminum-zinc plating is needed to perform anticorrosion treatment after support members are processed, and the production period is long. The existing photovoltaic support technical scheme is as shown in figure 1, and a support upright post is welded at the top of a tubular pile. The photovoltaic module is fixed on the purline through the connecting piece. The photovoltaic bracket is made of Q235/Q235B or Q345 and is subjected to surface hot-dip galvanizing treatment. The objective disadvantages of the existing photovoltaic support technology are as follows: 1. support stand and tubular pile welding need carry out rust-resistant treatment, and when the tubular pile was too high, construction and later maintenance were inconvenient, and there is the potential safety hazard in the welding part corrosion. 2. The purlins cross the photovoltaic module and can influence the back power generation of the photovoltaic module if the purlins are used for installing the double-sided battery module. 3. The steel consumption is more, the cost is higher, and the production cycle is long.

The utility model discloses a single pile support main material chooses high strength LQ550 steel for use, and the substrate is cold-base continuous hot-galvanize, and the back is accomplished in the support component processing, need not carry out anticorrosive treatment again, and production cycle is shorter. Aiming at the characteristics of double-sided battery photovoltaic module power generation, the photovoltaic support is prevented from shielding the back of the photovoltaic module as much as possible, and purlines and secondary beams are uniformly distributed at the edge or the seam of the photovoltaic module.

The technical scheme of the utility model is that:

the utility model provides a two-sided photovoltaic module light steel photovoltaic support that excels in, includes precast tubular pile, triangle-shaped main support, staple bolt, its characterized in that: triangle-shaped main support by front column, rear column, preceding bracing, back bracing, sloping and crossbeam are constituteed, front column, rear column link into an integrated entity through the crossbeam, preceding bracing both ends link to each other with sloping front end and front column bottom respectively, back bracing both ends link to each other with sloping rear end and rear column bottom respectively, precast tubular pile fixes subaerial, the front column of triangle-shaped main support, the rear column embolias precast tubular pile upper end and fixes on precast tubular pile through two staple bolts, and the crossbeam card is in precast tubular pile top.

The front upright post, the rear upright post, the front inclined strut, the rear inclined strut, the inclined beam and the cross beam of the triangular main bracket are all made of LQ550 steel.

The triangular main bracket of the utility model adopts the new material of LQ550 steel, the surface cold base continuous hot galvanizing is adopted, the secondary galvanizing is not needed after the section bar processing is finished, and the LQ550 steel has the characteristics of high strength, less steel consumption, short production period, strong corrosion resistance, cost saving and the like; of course, profiles of other materials can be used instead, but the requirements of load and design are met. The triangular main support is additionally provided with the cross beam on the upper part of the precast tubular pile, so that the installation is convenient, and the support is prevented from sliding down integrally. All the connecting points are connected by bolts, so that potential safety hazards caused by welding are avoided. All the support members are distributed at the edge of the photovoltaic module, so that the support members are prevented from shielding the back of the double-sided photovoltaic module, shielding of the support structure on the back of the photovoltaic module is minimized, and the power generation efficiency of the photovoltaic module is improved.
