In other embodiments, the first column 2 and the second column 4 can also be a rectangular tubular structure; the reducer 3 in this embodiment is a dual-output shaft reducer 3, and it has its own brushless motor, which has higher precision, higher durability, and a self-correcting angle function; the outer ring of the bearing 6 is a circular arc structure, which fits with the inner wall of the bearing seat 5 to achieve rotation, and the inner ring of the bearing 6 is a square hole, which fits with the rotary shaft 1 and rotates synchronously with the rotary shaft 1. This embodiment also includes a control cabinet 12, and the reducer 3 is controlled by the control cabinet 12.

[0040] The reducer 3 is mounted on the first column 2, and the output ends on both sides of the reducer 3 are connected to the rotating shaft 1. In this embodiment, the output ends of the reducer 3 are fixed to the rotating shaft 1 by screwing, so that the reducer 3 can drive the rotating shaft 1 to rotate. The second columns 4 are respectively arranged at intervals on both sides of the first column 2. A plurality of second columns 4 can be arranged at intervals on both sides of the first column 2 according to the length of the rotating shaft 1. The bearing seat 5 is mounted on the second column 4, and the bearing 6 is rotatably connected to the bearing seat 5 and is sleeved with the rotating shaft 1. The bearing seat 5 is used to support the rotating shaft 1, and the bearing 6 is in contact with the rotating shaft 1 to achieve synchronous rotation.

[0041] When in use, the photovoltaic panel body is installed along the length direction of the rotating shaft 1. The rotating shafts 1 on both sides can be rotated synchronously through the reducer 3 to drive the photovoltaic panel body to rotate, so that the angles of multiple groups of photovoltaic panel bodies can be adjusted simultaneously.

[0042] In some embodiments, the single-axis photovoltaic tracking bracket also includes a swivel base 7 and a column top seat 8. The swivel base 7 is height-adjustable and installed between the first column 2 and the reducer 3. In this embodiment, the reducer 3 is screwed to the swivel base 7, so that the height of the reducer 3 can be adjusted; the column top seat 8 corresponds one-to-one to the second column 4 and is height-adjustable and installed between the second column 4 and the bearing seat 5. In this embodiment, the bearing seat 5 is screwed to the column top seat 8, so that the height of the swivel shaft 1 can be adjusted, so that the height difference between the first column 2 and the second column 4 can be reduced by adjusting the height between the swivel base 7 and the column top seat 8, so that the photovoltaic panel body can be better supported at a height, so that the photovoltaic panel body can also be more stable during rotation.

[0043] Reference Figure 2 In some embodiments, the single-axis photovoltaic tracking bracket further includes a first bolt 9 and a first nut 10. The swivel base 7 is provided with first adjustment holes. In this embodiment, four first adjustment holes are provided on each side of the swivel base 7, for a total of eight. The first column 2 is provided with at least two first matching holes 11 along the height direction. In this embodiment, four first matching holes 11 are provided on each side of the first column 2 along the height direction, for a total of sixteen first matching holes 11. During installation, the first bolt 9 is sequentially passed through the first matching holes 11 and the first adjustment hole and is screwed into the first nut 10. Therefore, the height of the swivel base 7 can be adjusted by aligning different first matching holes 11 with the first adjustment holes.

During installation, the second bolt 13 passes through the second matching hole and the second adjustment hole in sequence, and is screwed with the second nut 14. Therefore, by adjusting the alignment of the second adjustment hole and the second matching hole, the height difference between the second column 4 and the first column 2 can be adjusted to make the height of the photovoltaic panel body consistent. In this embodiment, reinforcement strips 15 are also integrally connected to both sides of the column top seat 8, so that the rotating shaft 1 can be stably supported.

[0045] Continue to refer to Figure 3In some embodiments, the single-axis photovoltaic tracking bracket further includes a bearing stopper 16, which is connected to the rotating shaft 1 and abuts against one side of the bearing 6. The bearing stopper 16 is used to abut against the bearing 6, so that the bearing 6 in the bearing seat 5 can be stably located in the bearing seat 5 during rotation.

[0046] In some embodiments, the bearing stopper 16 includes two bearing stoppers 161 and a connecting member 162. The bearing stoppers 161 are arranged opposite to each other and abut against the bearing 6. The connecting member 162 is connected between the two bearing stoppers 161. In this embodiment, two connecting members 162 are provided. The connecting member 162 includes a bolt and a nut. The bolt passes through the two bearing stoppers 161 in sequence and is screwed to the nut, so that a U-shaped bearing 6 is formed to fit the rotating shaft 1. Due to the friction between the bearing 6 and the rotating shaft 1, the bearing 6 can be abutted and limited, so that the bearing 6 can stably rotate synchronously with the rotating shaft 1. It should be noted that the two sides of the bearing 6 itself have parts that abut against the outer peripheral side of the bearing seat 5. The bearing stopper 16 plays an auxiliary role.

[0047] In some embodiments, the single-axis photovoltaic tracking bracket further includes at least two purlins 17, which are spaced apart along the length of the rotating shaft 1. A number of purlins 17 are provided at intervals corresponding to the length of the rotating shaft 1. In this embodiment, U-bolts 18 are provided. After being fitted onto the rotating shaft 1, U-bolts 18 pass through the purlins 17 and are screwed to the purlins 17. Purlins 17 are used to mount the photovoltaic panels, allowing for easy installation and allowing for the spacing between panels to be adjusted to accommodate different sizes.

[0048] In some embodiments, the single-axis photovoltaic tracking bracket further includes a reinforcement plate (not shown in the figure), which is installed in the purlin 17. Increasing the thickness of the purlin 17 can enhance the connection strength between the purlin 17 and the rotating shaft 1, so that the photovoltaic panel can be supported more stably.

[0049] Reference Figure 4 In some embodiments, the single-axis photovoltaic tracking bracket further includes a damper 19 and a swing arm 20. The swing arm 20 is mounted on the rotating shaft 1. In this embodiment, the swing arm 20 is fixed to the rotating shaft 1 by screwing. One end of the damper 19 is hinged to the second column 4, and the other end is hinged to the end of the swing arm 20 away from the rotating shaft 1. In this embodiment, dampers 19 are provided on the two outermost second columns 4 at both ends of the rotating shaft 1 in the longitudinal direction. In other embodiments, the number and position of the dampers 19 can be set according to actual conditions, so that the dampers 19 can provide a damping force exceeding 10,000 N under strong winds to reduce the impact of wind vibration on both ends of the bracket.

[0050] The implementation principle of a single-axis photovoltaic tracking bracket in the embodiment of the present application is: when installing the photovoltaic panel body, multiple groups of photovoltaic panel bodies are installed along the length direction of the rotating shaft 1, and the rotating shaft 1 is supported by the bearing seat 5. At the same time, the bearing 6 can enable the rotating shaft 1 to rotate flexibly when the reducer 3 drives the rotating shaft 1 to rotate; therefore, the angles of multiple groups of photovoltaic panels can be adjusted at the same time by driving the rotating shaft 1 to rotate through the reducer 3.
