Fig. 7 is a schematic structural diagram showing the photovoltaic array support angle adjustment system mounted on the vertical column 21' (for example, a middle vertical column). With combined reference to fig. 2, fig. 3A and fig. 7, according to the utility model discloses a photovoltaic array support angle adjusting system, for example install on the stand 21' that is located the intermediate position, through controller 616 on portable electric putter 61, can control the flexible of interior pole 613 of electric putter 61, interior pole 613 drives the swing arm 43 swing to drive the rotation of photovoltaic main shaft 51. Since the photovoltaic modules 25 mounted on the non-central vertical columns 21 'are also angularly adjusted by the rotation of the same photovoltaic main shaft 23, a row (column) of photovoltaic modules 25 can be driven by the portable electric push rod 61 mounted on the central vertical column 21', and the angle of the photovoltaic modules 25 in the north-south direction, for example, can be adjusted to face the sun.

Referring to fig. 2 to 7, a method for adjusting an angle of a photovoltaic array support according to a preferred embodiment of the present invention will be described in detail. In step S1, the portable electric push rod 61 is first attached to the center pillar 21' and the swing arm 43. Specifically, the annular connecting portion 6131 of the telescopic inner rod 613 of the electric push rod 61 is sleeved into the push rod connecting portion 432 of the swing arm 43, and at the same time, the pin 614 is inserted into the trunnion 612 of the electric push rod 61 and the push rod mounting portion 412 of the push rod seat plate 41 fixed on the middle upright post 21', for example, so as to mount the electric push rod 61 in place. In step S2, the arch bolts 271 mounted on all the columns 21, including the center column 21', are loosened. Specifically, the nut 272 of the arch bolt 271 is loosened from the arch bolt 271 but is not disengaged from the arch bolt 271. In step S3, the swing arm 43 is driven by the electric push rod 61 to adjust the orientation of the photovoltaic module 25. Specifically, the controller 616 on the electric push rod 61 controls the extension and retraction of the inner rod 613 thereof, and drives the swing arm 43 to swing, so as to adjust the orientation of the photovoltaic module 25 in the north-south direction, for example. In step S4, the arch bolt 271 attached to the column 21 is fastened. Specifically, the nuts 272 of the arch bolts 271 mounted on the columns 21 are tightened on the arch bolts 271 so as to position the photovoltaic module 25 by the arch 27. In step S5, the electric push rod 61 is detached from the center pillar 21'.

In another preferred embodiment of the method for adjusting the angle of a photovoltaic array bracket according to the present invention, the step S4 is further divided into: in step S41, the arch bolts 271 attached to the other columns 21 except the center column 21' are fastened. Specifically, nuts 272 of arch bolts 271 installed on the other columns 21 except the center column 21' are tightened on the arch bolts 271 so as to position the photovoltaic module 25 by the arch 27; in step S42, after the electric push rod 61 is detached from the center pillar 21 ', the arch bolt 271 attached to the center pillar 21' is fastened.

In another preferred embodiment of the method for adjusting the angle of a photovoltaic array bracket according to the present invention, the step S5 is further divided into: in step S51, the electric push rod 61 is released from the push rod seat plate 41. Specifically, the electric push rod 61 is released from the electric push rod seat plate 41 by, for example, a controller 616 on the electric push rod 61 to control the switch to jog. This is because the pin 614 is relatively stressed when the electric push rod 61 is operated, and is combined with the mounting part 611 of the push rod 61 and the push rod seat plate 41 tightly, so that the electric push rod 61 is not easy to detach, and the pin 614 can be loosened gradually by using the inching mode of the control switch, so that the pin 614 can be conveniently pulled out from the mounting part 611 and the seat plate 41, and finally the electric push rod 61 is detached. In step S52, the electric push rod 61 is detached from the center pillar 2'. Those skilled in the art will appreciate that the detached power push rod 61 can be mounted on another row (column) of photovoltaic supports to continue the angular adjustment of the photovoltaic array support.
