[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] To make the above objects, features, and advantages of the present invention more obvious and understandable, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0041] As Figures 1-10 shown, this embodiment provides a flexible inclined single-axis tracking bracket. The photovoltaic matrix is composed of four rows of photovoltaic arrays. The photovoltaic arrays have a plurality of photovoltaic panels 1. Figure 1 Among them, the rear part of the photovoltaic array is not installed with photovoltaic panels 1. The flexible inclined single-axis tracking bracket includes: an installation bracket 2, the photovoltaic panel 1 is fixedly arranged on the installation bracket 2, and the lower surface of the installation bracket 2 has a rotating connection part 201; a flexible bracket, the flexible bracket has a steel strand, and the upper and lower ends of the installation bracket 2 are rotatably arranged on the steel strand; a pulling rope 15, one or more pulling ropes 15 are arranged for each row of photovoltaic arrays, and the plurality of rotating connection parts 201 of the same row of photovoltaic arrays are all fixedly connected to the pulling rope 15; a steering pulley 3, at least one steering pulley 3 is arranged for each row of photovoltaic arrays, and the pulling ropes 15 of each row of photovoltaic arrays are all connected to the output end of the driving mechanism 4 through the steering pulley 3, and the driving mechanism 4 can drive the plurality of photovoltaic panels 1 of the photovoltaic matrix to rotate through the pulling rope 15.

[0042] As Figure 2 shown, the installation bracket 2 includes: a vertical bar 203, the upper and lower ends of the vertical bar 203 are rotatably arranged on the steel strand; a plurality of cross bars 202 are evenly spaced on the left and right sides of the vertical bar 203, the photovoltaic panel 1 is fixedly arranged on the upper surfaces of the cross bar 202 and the vertical bar 203, and the rotating connection part 201 is fixedly arranged on the lower surface of the vertical bar 203 and / or the cross bar 202. As Figure 3As shown, the rotating connection part 201 is generally triangular. A clamping part is arranged near the bottom of the rotating connection part 201. The pulling rope 15 can be clamped into the clamping part to fix the pulling rope 15 to the rotating connection part 201. The photovoltaic panel 1 is installed on the mounting rack. The schematic diagram after installation is as Figure 4 shown.

[0043] As Figure 1 shown, the flexible support includes: a high-position column 5 arranged along the length direction of the photovoltaic array. A first steel strand 7 is fixedly arranged between the high-position columns 5; a low-position column 6 arranged along the length direction of the photovoltaic array. A second steel strand 8 is fixedly arranged between the low-position columns 6; the second steel strand 8 is lower than the first steel strand 7. The upper and lower ends of the longitudinal rod 203 are respectively rotatably arranged on the first steel strand 7 and the second steel strand 8. An oblique angle is formed between the high-position column 5 and the low-position column 6, so that the photovoltaic panel 1 can be inclined and arranged on the mounting bracket 2 (tilted in the north-south direction). The high-position columns 5 or the low-position columns 6 between different photovoltaic arrays are fixed by flexible stay cables. An additional fixed column needs to be arranged on the high-position column 5 at the end of the photovoltaic array. The fixed column is similar in height to the low-position column 6 and is also connected and fixed by a flexible stay cable.

[0044] As Figure 5 shown, it further includes: an end connecting plate 9 located at the upper and lower ends of the longitudinal rod 203 and fixedly connected to the first steel strand 7 and the second steel strand 8 respectively through fastening bolts. The upper and lower ends of the longitudinal rod 203 are rotatably arranged on the end connecting plate 9 through bearings, which can realize the rotation of the photovoltaic panel 1 in the east-west direction but will not cause movement in the east-west direction.

[0045] As Figure 6 shown, a fixed pulley 10 is arranged on the high-position column 5 at the end of the photovoltaic array. As Figure 7 shown, upper adapter parts 11 and lower adapter parts 12 are arranged on the remaining high-position columns 5. As Figure 8 shown, in this embodiment, two steering pulleys 3 are arranged simultaneously in the same photovoltaic array. The setting position is at Figure 1 B in. The pulling rope 15 extends respectively in the east-west direction from B, passes through a plurality of upper adapter parts 11 on both sides of the same photovoltaic array, and is wound around the fixed pulley 10 at the two ends of the photovoltaic array on both sides as Figure 6 shown. Then the pulling rope 15 extends in the reverse direction, passes through a plurality of lower adapter parts 12, and is respectively wound around the two steering pulleys 3. Finally, the two ends of the pulling rope 15 are joined at the driving mechanism 4, and the driving mechanism 4 drives the pulling rope 15 to move.

[0046] As Figure 9 shown, it further includes: an auxiliary pulley 13 arranged in the two outermost photovoltaic arrays of the photovoltaic matrix ( Figure 1At point A in the figure, a driving rope 14 is wound around the auxiliary pulley 13. The driving rope 14 is a closed loop rope, with both ends wound around two auxiliary pulleys 13 respectively, and the driving rope 14 runs across the entire photovoltaic matrix in the north-south direction. The driving rope 14 is connected to the driving mechanism 4 and can slide along the auxiliary pulley 13; the pulling ropes 15 of multiple photovoltaic arrays are fixedly connected to the driving rope 14 after being redirected by the redirecting pulleys 3. As shown in Figure 8 In the figure, the pulling rope 15 is diffracted around two redirecting pulleys 3, then extends towards the driving mechanism 4 and is connected downward to the driving rope 14.

[0047] As shown in Figure 1 the redirecting pulleys 3 of multiple rows of photovoltaic arrays are located on the same straight line ( Figure 1 the straight line where the two auxiliary pulleys 13 are located in the figure, that is Figure 1 at point A in the figure), and the driving mechanism 4 and the auxiliary pulley 13 are generally located at the center of the photovoltaic array, which is convenient for the pulling ropes 15 of each photovoltaic array to be connected to the driving rope 14 and also convenient for the driving rope 14 to be connected to the driving mechanism 4. As shown in Figure 10 the figure, the driving mechanism 4 is arranged on the support column 16, and the driving mechanism 4 is connected to two strands of the driving rope 14 through two connecting ropes. When the driving mechanism 4 is started, one strand of the driving rope 14 moves northward and the other strand of the driving rope 14 moves southward. In this way, the pulling ropes 15 corresponding to the upper connecting parts can move in the east-west direction, and the moving directions of the pulling ropes 15 corresponding to the lower connecting parts are opposite. The pulling ropes 15 corresponding to the upper connecting parts drive the mounting bracket 2 to rotate in the east-west direction through the rotating connecting part 201, completing the adjustment of the rotation angle of the photovoltaic panel 1 so that the photovoltaic panel 1 always faces the sun direction.

[0048] It should be noted that when the pulling rope 15 moves, the rotating connecting part 201 can rotate, but the rotating connecting part 201 will drive the pulling rope 15 to move slightly upward. Since the pulling rope 15 is flexible and there is sufficient clearance between the pulling rope 15 at the photovoltaic panel 1 and the fixed pulley 10, the slight upward movement of the pulling rope 15 here does not affect the stability of the overall structure, and the photovoltaic panel 1 can rotate without damage to the pulling rope 15.

[0049] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0050] The embodiments described above are only descriptions of the preferred embodiments of the present invention, and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various deformations and improvements made by those of ordinary skill in the art to the technical solutions of the present invention shall fall within the protection scope determined by the claims of the present invention.
