Height-adjustable photovoltaic support

The utility model discloses a height-adjustable photovoltaic support which is characterized in that the height-adjustable photovoltaic support comprises an upper stand column (1), a lower stand column (2), a pile foundation (3), a front inclined strut (4), a rear inclined strut (5), a purline (6) and an inclined beam (7), the lower stand column (2) and the pile foundation (3) are connected in a direct insertion mode, and the front inclined strut (4) and the rear inclined strut (5) are fixed on the upper stand column (1) through bolts. And the inclined beam (7) is fixed on the upper upright post (1), the front inclined strut (4) and the rear inclined strut (5) through bolts. As the upper and lower upright posts of the bracket are adjustable, the bracket can better adapt to mountain fluctuation. The high-strength weathering steel material can effectively solve the problem of atmospheric corrosion and the problem of steel content of the support, and is beneficial to the investment cost. All the supports are inst
