[0017] 1. Conventional photovoltaic brackets in the prior art include an inclined beam, a front column connected to the front side of the inclined beam, and a rear column connected to the rear side of the inclined beam. The rear column is higher than the front column so that the inclined beam is inclined with the front lower and the rear higher. Therefore, there is a certain angle between the photovoltaic components installed on the photovoltaic bracket and the horizontal plane, but the angle is fixed and does not change.

[0018] In order to solve the problem of manually adjusting the angle of the photovoltaic bracket based on the existing technology, a height adjustment component is arranged between the top of the front column and the inclined beam. The angle of the photovoltaic bracket is adjusted by raising or lowering the height adjustment component. By adjusting the angle, the photovoltaic component can always be in the optimal inclination state, which helps to improve its power generation efficiency and can adapt to different seasons and weather conditions to make full use of solar energy resources.

[0019] The height adjustment component includes four connecting pieces connected end to end to form a rhombus, and the four corners of the rhombus are provided with connecting pieces hinged to the ends of the corresponding two connecting pieces, so that the height adjustment is achieved through the structural changes of the rhombus.

[0021] Moreover, a vertical rod is arranged at the lower part of the upper connecting piece to provide an additional support point, which can increase the vertical support force and stability of the height adjustment component, reduce the possibility of tilting or sliding during use, and make the lifting and lowering operation of the height adjustment component smoother and more labor-saving. The nut slider can improve the load-bearing capacity, stability and ease of use of the height adjustment component.

[0022] 2. The nut slider is rectangular and can be movably inserted into the rectangular slide groove. In this way, the nut slider cannot rotate. During the cooperation with the handle rod, the handle rod moves left and right, driving the diamond to stretch or shrink up and down. The height adjustment of the entire height adjustment assembly is achieved while the structure changes.

[0023] 3. The nut slider is connected with a limit screw, which passes through the limit slot to limit the nut slider in the slot and guide the nut slider to slide up and down along the slot.

[0024] 4. The upper connecting piece, the middle connecting piece and the lower connecting piece are U-shaped structures, and the two side walls of the U-shaped structure are provided with transition grooves to facilitate the ends of the connecting pieces to be hinged in the transition grooves.

[0026] 6. Since a convex column is provided on the upper part of the upper connecting member, the convex column is connected to the U-shaped hinge, and the hinge is connected to the inclined beam through the upper bolt. In this way, the height adjustment component is adjusted by the limitation of the U-shaped hinge and the convex column, and the horizontal position between the height adjustment component and the inclined beam is kept fixed.

[0027] 7. Since the top of the front column is connected with a column cap, the lower connecting piece is fixed to the column cap with a lower bolt, and the column cap and the front column are fixed with a through-column bolt, that is, both are connected with bolts, thus facilitating the fixing of the height adjustment assembly to the front column.

[0028] 8. The connecting piece is an alloy steel sheet, and the connecting piece, the middle connecting piece and the lower connecting piece are all one-piece molded structures, which not only have high structural strength but also are easy to mold, thus reducing the overall cost of manufacturing and photovoltaic brackets.

[0029] 9. Since the inclined beam and the cross beam are both C-shaped or U-shaped steel, the front column and the rear column are both square steel pipes, which are conventional materials, it is convenient to reduce the procurement cost and convenient to fix them on the bottom wall of the inclined beam with bolts.

[0030] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings.
