Since most of the photovoltaic projects in the southern region are mountainous, the mountain slopes are ups and downs, and the construction environment is bad due to a series of reasons such as deep silt and too much water accumulation at the construction site due to abundant rainwater. The conventional scaffolding (mobile scaffolding, portal scaffolding) used for the installation of photovoltaic modules in photovoltaic plants is difficult to set up. Another commonly used hook scaffolding method loads additional stress on the inclined beams on the photovoltaic bracket, which easily causes the steel structure of the photovoltaic bracket to be deformed. Its construction cost is high, there are safety hazards during use, and it also seriously affects the construction progress.

[0003] Although CN 205804912 U also discloses a special scaffold for installing photovoltaic modules, the scaffold is hooked on the existing photovoltaic support in a hanging manner. During use, this hanging structure is prone to shaking, which leads to the risk of falling, and the safety during the construction process cannot be guaranteed. Utility Model Content

[0032] In the utility model: it can be applied to a variety of photovoltaic bracket foundations. The current example is a concrete cast-in-place pile foundation. A drilling machine is used to drill holes and concrete is cast in situ. The photovoltaic bracket is connected to the lower column 8 of the photovoltaic bracket through the embedded parts 16 of the cast-in-place pile.

Multiple photovoltaic brackets are connected through the upper purlin 13 and connected into a whole, and then the photovoltaic module 14 is installed on the purlin 13. All connection parts are connected by high-strength bolts; during the use of the utility model, the auxiliary bracket clamp 1 is clamped on the lower column 8 of the photovoltaic bracket of the photovoltaic bracket, so that the auxiliary frame 2 connected to the bracket clamp 1 is firmly connected to the lower column 8 of the photovoltaic bracket. Under this premise, the upper suspension rod 3 and the lower suspension rod 4 and the reinforcing rod 6 are connected by high-strength bolts. Make the auxiliary bracket form a whole. After installing the auxiliary brackets on multiple groups of photovoltaic brackets, a springboard is placed on one or both sides to form a stable working platform. In actual application, after the first assembly of the auxiliary bracket is completed, after the current working surface is completed, the overall disassembly can be completed by loosening the clamps, and then after being carried by the operators, it can be directly installed on the photovoltaic bracket of the next working surface. Effectively improve the working efficiency and construction progress.

[0035] In the present invention, if auxiliary brackets are added on both sides of the row of photovoltaic brackets, the difference between the highest point and the lowest point of the photovoltaic module installation is close to 1 meter due to its own slope. In order to make it easier for operators to construct, the length of the support rod 3 on one side will be lengthened. However, the number of parts will not be increased. After disassembly, the longest rod is 2.5 meters long, which is convenient for carrying and transportation.
