[0034] like Figures 1-4As shown, another embodiment shows a concrete flat roof photovoltaic support fixed on a concrete cement pier block 1 with a horizontal top surface, including multiple groups of U-shaped embedded parts 2 fixed on the concrete cement pier block 1, multiple groups of inclined beams 3 for supporting and installing photovoltaic panel assemblies 4, a first triangular connecting piece 51 hinged to the lower end of the inclined beam 3, and a second triangular connecting piece 52 fixedly connected to the higher end of the inclined beam 3; the first triangular connecting piece 51 is fixedly connected to the U-shaped embedded part 2; the second triangular connecting piece 52 is fixedly connected to the U-shaped embedded part 2 through an adjustable component 6; the first triangular connecting piece 51 and the second triangular connecting piece 52 have the same specifications and dimensions; the adjustable component 6 is hinged to the second triangular connecting piece 52;

[0035] Both the first triangular connecting piece 51 and the second triangular connecting piece 52 respectively include a U-shaped main body; the U-shaped main body includes triangular side plates 53 on both sides and a first bottom plate 54 connecting the two triangular side plates 53; the first bottom plate 54 of the first triangular connecting piece 51 is in contact-fixed connection with the top surface of the concrete cement pier block 1 through the U-shaped embedded part 2, and the triangular side plate 53 of the first triangular connecting piece 51 is hinged to the lower end of the inclined beam 3; the first bottom plate 54 of the second triangular connecting piece 52 is in contact-fixed connection with the inclined beam 3, and the triangular side plate 53 of the second triangular connecting piece 52 is hinged to the adjustable component 6;

[0036] The adjustable component 6 includes a base 61 and a U-shaped column 62 detachably threadedly connected to the base 61; the base 61 includes a second bottom plate 611 arranged horizontally and a U-shaped connecting plate 612 perpendicularly connected to the second bottom plate 611; the U-shaped column 62 is in contact-fixed connection to the inner wall of the U-shaped connecting plate 612 through a bolt connection; the second bottom plate 611 is in contact-fixed connection with the top surface of the concrete cement pier block 1 through the U-shaped embedded part 2;

[0037] The U-shaped connecting plate 612 includes a third bottom plate 613 and first side plates 614 symmetrically connected to both sides of the third bottom plate 613; the third bottom plate 613 is provided with at least three first circular grooves 615 arranged in a straight line; the U-shaped column 62 includes a fourth bottom plate 621 threadedly connected to the third bottom plate 613 and a second side plate 622 in contact connection with the first side plate 614; the bottom end of the U-shaped column 62 is bolt-connected to different first circular grooves 615 of the U-shaped connecting plate 612 according to actual needs, and the top end of the U-shaped column 62 is hinged to the triangular side plate 53 of the second triangular connecting piece 52.

At this time, the pointing of the angle indicating needle 521 of the second triangular connecting member 52 fixed on the inclined beam 3 will also change around the hinge hole 623. The installer can read the current inclination angle in real time until the inclined beam 3 is adjusted to the preset required angle, thereby completing the installation of the inclined beam 3.

[0039] Furthermore, in these embodiments, a pointer platform 522 is provided at the corner of the triangular side plate 53 where the angle indicating needle 521 is provided, reducing the interference of the corner of the triangular side plate 53 on the rotation of the pointer.
