According to the difference of regulation mode, fixed adjustable photovoltaic support mainly has at present: push-pull rod type, semi-arc type and jack type.

The push-pull rod type fixed adjustable support realizes angle adjustment of the photovoltaic support by utilizing the back-and-forth push-and-pull movement of the support inclined support rod in the clamping groove of the horizontal rod at the bottom of the foundation, and the support is fixed by bolt hole positions after the angle adjustment is finished.

The semi-circular arc type fixed adjustable support utilizes hinged connection of the support oblique beam and the A-type vertical rod to adjust the angle of the photovoltaic support, and the semi-circular arc support rod and the A-type vertical rod are fixed through bolt hole positions after the angle adjustment is finished.

The fixed adjustable support of jack formula is through connecting the flexible support angle of adjusting of rhombus jack between support sloping and montant, and the self-locking realization of back support through the jack is fixed after angular adjustment finishes.

According to the structure forms of the fixed adjustable supports, the adjusting angles of the first two supports are controlled by the number of the bolt holes, stepless adjustment can be realized by fixing the angle of the adjustable support through the jack, and the adjusting times can be increased or decreased according to specific conditions. The fixed adjustable support of jack formula of generally adopting in the trade at present, though jack formula photovoltaic support exists above advantage, but the adjustable photovoltaic support of jack formula also has following problem: and (1) as the diamond-shaped jack is adopted as an adjusting tool, a diamond-shaped jack is required to be arranged at each pile foundation as a supporting and adjusting component. This results in an excessive investment cost for this type of support; (2) because the adopted rhombic jack is designed by an open screw rod and a nut, the situation that the transmission mechanism is blocked by outdoor sand can occur in the using process, and the subsequent maintenance and replacement cost is too high.
