[0050] The working principle of the adjustable photovoltaic support suitable for complex mountainous terrain proposed in this embodiment is as follows:

[0051] First, perform line measurement at the location where the support needs to be installed, and perform foundation construction after determining the foundation position to ensure that the front column 1 and the rear column 2 can be stably fixed to the ground. Then install the front column 1 and the rear column 2: insert the connecting piece two 9 into the connecting piece one 8 to ensure smooth sliding between the two without any obstacles. At this time, the overlapping length of the connecting piece one 8 and the connecting piece two 9 should be greater than the length required for the installation of the fastener 10. According to the terrain and lighting conditions, manually slide the connecting piece two 9 in the connecting piece one 8 to the desired position. A ruler or measuring tool can be used to ensure the accuracy of the adjustment. After adjusting the position of the connecting piece two 9, pass the fastener 10 through the bolt hole of the connecting piece one 8 and place it below the connecting piece two 9. Then use a hexagonal wrench or other tool to tighten the hexagonal bolt 11 on the fastener 10, so that the nut on the lower part of the fastener 10 tightly fits into the groove of the connecting piece two 9. The friction generated by tightening fixes the connecting piece one 8 and the connecting piece two 9, preventing them from moving relative to each other.

[0052] Then install the diagonal beam 5, front support rod 3 and rear support rod 4, and assemble the inner and outer connecting pieces of the diagonal beam 5, front support rod 3 and rear support rod 4 according to the assembly method of the column. Ensure that the connection between each part is stable and reliable. Adjust the length of the diagonal beam 5, front support rod 3 and rear support according to the terrain and installation requirements of the photovoltaic module. Adjust the length by sliding the inner and outer connecting pieces and tightening the fastener 10. After adjusting the length, adjust the installation angle of the diagonal beam 5, front support rod 3 and rear support according to the terrain and lighting conditions.

[0053] The purlins 6 are installed on the inclined beams 5 at a predetermined interval. The purlins 6 are used to support the photovoltaic modules and ensure their stable installation. The photovoltaic modules are installed on the purlins 6 according to the design requirements. The interval and installation angle of the photovoltaic modules are ensured to meet the design requirements. If the measurement shows that the angle and position deviate from the design, the foregoing steps can be repeated to adjust the support until the design requirements are met.

[0054] After the installation is completed, the entire photovoltaic support system is debugged and inspected. It is ensured that the connection between the components is stable and there is no loosening phenomenon, the installation angle and ground clearance of the photovoltaic modules meet the design requirements. At the same time, the stability and safety of the support system are checked to ensure that it can normally operate under complex mountainous terrain and withstand various natural environmental tests.

[0055] If the support needs to be adjusted during operation, the foregoing steps can also be repeated to adjust the overall structure of the support to meet the operation requirements and the optimal inclination angle, thereby ensuring the maximum power generation.
