The conventional mountain photovoltaic support adopts a flat open area photovoltaic support arrangement scheme, the whole square matrix is arranged in a rectangular shape, the heights of the upright posts are uniform, and no purline supporting structure is arranged. In mountain regions with large east-west gradients, in order to meet the requirements of smooth installation of the square matrix solar panels, the heights of stand columns of each support are required to be respectively designed according to the actual terrain gradient where the square matrix is located, so that the standard sizes of the stand columns are large, factory processing is difficult, and the steel consumption is increased. If on-site upright post cutting is performed, the construction cost and period are increased, and the progress and cost control of the whole project are affected. Meanwhile, as the terrain has a large east-west gradient, when the photovoltaic assembly is arranged along the slope, the east-west direction structure stress is changed from tension and compression into a stretch bending state and a compression bending state, and the whole structure stress is unfavorable. When the east-west gradient is smaller, the single-upright scheme has the advantage of construction cost. If the east-west slope is larger, the single-upright structure is still adopted, the inclined beam and the upright are cantilever members, the overall stability is poor, and the section sizes of the inclined beam and the upright are required to be greatly increased.
