[0032] (Example 1)

[0033] like Figures 1 to 4 The photovoltaic tracking bracket shown includes a column assembly 1, a main beam 2, a support bar 3, a cross beam 4, a mounting seat 5 and a driving assembly 6. There are two column assemblies 1 and they are arranged opposite to each other. The main beam 2 is connected between the two column assemblies 1 and the two ends are rotatably connected to the tops of the two column assemblies 1 respectively. The support bars 3 are arranged in a fixed and equidistant manner along the length direction of the main beam 2 and are parallel to each other. There are two cross beams 4, which are symmetrically and parallelly arranged on both sides of the main beam 2. Each support bar 3 is fixedly connected to the two cross beams and connected as a reinforcing rib, and the photovoltaic panel is installed thereon. There are two mounting seats 5, which are fixedly installed at the two ends of any cross beam 4 respectively. The upper end of the driving assembly 6 is hinged to one of the mounting seats 5, and the lower end is hinged to the lower end of the column assembly 1. The driving assembly 6 drives the cross beam 4 on one side to move, thereby driving the photovoltaic panel to adjust its angle. Compared with the traditional structure, the support point of the driving assembly 6 is adjusted from the mounting seat extending from the main beam 2 to the supporting purlin 3, and a crossbeam 4 is added for coordinated connection, which ensures the stability of the overall structure, abandons the complex mounting seat structure, saves the cost of the part, and effectively controls the cost; at the same time, the whole row of supporting purlins is connected by two crossbeams as reinforcement ribs. During operation, each supporting purlin can run synchronously, effectively reducing the height difference between the first and last supporting purlins, ensuring that the photovoltaic panels are in the same plane, and effectively reducing the shaking of the photovoltaic panels in windy weather, ensuring the stability of the whole frame, and improving the power generation efficiency.

[0034] Specifically, the column assembly 1 includes a mounting base plate 1-1 and a column 1-2 vertically fixed on the mounting base plate 1-1. A bearing hoop 7 is fixed on the top of the column 1-2. A rotating bearing 8 is arranged inside the bearing hoop 7. The outer ring of the rotating bearing 8 is concentrically matched with the bearing hoop 7, and the inner ring is fixedly connected with the main beam 2, so as to realize the rotation connection between the main beam 2 and the column assembly 1. The integral rotating hoop bearing structure is adopted to ensure the dustproof and sealing properties of the rotating bearing 8 and the stable operation of the rotating bearing 8. An oil filling hole 7-1 is provided on the outer circumferential surface of the bearing hoop 7, and an annular oil filling groove 7-2 is provided on the circumferential surface of the inner hole. The oil filling hole 7-1 is connected to the oil filling groove 7-2.

[0035] The column assembly 1 also includes a connecting seat 1-3 fixedly provided on the mounting base plate 1-1. The driving assembly 6 adopts an electric push rod with a simple structure and stable power. The cylinder body of the electric push rod is hinged to the mounting seat 5, and the end of the screw rod is hinged to the connecting seat 1-3, so that the lower mounting point of the driving assembly 6 can be directly placed on the ground base. In severe weather, wind pressure and snow pressure are transmitted to the ground base through the driving assembly, which effectively reduces the lateral force on the column body and prevents tipping.

[0036] Diagonal bracing rods 9 are symmetrically fixed on both sides of the column assembly 6. The diagonal bracing rod 9 on the side close to the mounting seat 5 is fixedly connected to the crossbeam 4 on that side through the mounting seat 5, and a connecting plate 10 is fixedly connected between the other diagonal bracing rod 9 and the end of the crossbeam 4 on the corresponding side. By adding the diagonal bracing rods 9, the overall structure is reinforced to further improve the stability of the overall structure.

[0037] Taking into account the influence of bad weather, this embodiment further provides mounting ears 11 symmetrically on both sides of the top of the column assembly 6. The mounting ears 11 are provided with inclined ropes 12 fixed to the ground. In windy weather, the wind pressure is transmitted to the ground, which effectively reduces the lateral force on the column and saves the material cost of the column.

[0038] The support bar 3 is a hollow square tube with an opening facing upwards. A plurality of hollow waist-shaped holes are arranged equidistantly along the length direction at the bottom, which can guide the wind and reduce the influence of wind pressure. The two sides of the hollow square tube are provided with connecting parts 3-1 extending outwards, which are flush with the openings, so as to facilitate the installation of photovoltaic panels. A reinforcing block 13 is provided in the opening of the support bar 3 in the area corresponding to the main beam 1. A U-shaped rod 14 is sleeved on the main beam 1, and a short rod 15 is provided below. The two free ends of the U-shaped rod 14 first penetrate the reinforcing block 13, extend downward from both sides of the support bar 3 and penetrate the short rod 15, and then are threadedly tightened with locking bolts to realize the fixed connection between the main beam 1 and the support bar 3, which is convenient for assembly while ensuring a high connection strength, and further improves the stability of the overall structure.

[0039] The utility model adjusts the support point of the driving assembly 6 from the mounting seat extending from the main beam 1 to the supporting purlin 3, and adds a crossbeam 4 for coordinated connection, thereby ensuring the stability of the overall structure, abandoning the complex mounting seat structure, saving the cost of the component, and effectively controlling the cost; at the same time, the entire row of supporting purlins 3 are connected by two crossbeams 4 as reinforcing ribs, and each supporting purlin 3 can run synchronously during operation, effectively reducing the height difference between the first and last supporting purlins 3, ensuring that the photovoltaic panels are in the same plane, and effectively reducing the shaking of the photovoltaic panels in windy weather, ensuring the stability of the entire frame, and improving the power generation efficiency.
