The motor 8 can drive the rotating shaft 12 to rotate. The motor 8 can realize the independent driving of the adjusting frame 2 or the rotating shaft 12 through the driving switching mechanism, which is more convenient to use. The photovoltaic panel mounting bracket also includes a wind direction and speed sensor and a processor. Only one wind direction and speed sensor and processor can be set in a certain area. The processor analyzes the wind direction and speed information collected by the wind direction and speed sensor to determine whether the rope 15 needs to be tightened. When necessary, the winding drum 14 is rotated to wind the rope 15, thereby increasing the stability of the structure and avoiding damage to the structure caused by wind load.

[0030] In an embodiment of the present invention, the processor analyzes the wind direction and speed information collected by the wind direction and speed sensor, specifically including: calculating the first wind load based on the current orientation angle of the adjustment frame 2, wind direction data, wind speed data and photovoltaic panel area, the wind direction and speed information including wind direction data and wind speed data, when the first wind load is less than the wind load threshold, the task is terminated, indicating that no adjustment is required, and the wind load threshold is a fixed value set by the lifting; otherwise, it is necessary to determine the best orientation angle of the adjustment frame 2 within the orientation range according to the wind direction data, and the angle between the adjustment frame 2 and the wind direction at the best orientation angle is the smallest, and then calculate the second wind load based on the best orientation angle, wind direction data, wind speed data and photovoltaic panel area; determine whether the second wind load is less than the wind load threshold, and if so, adjust the orientation of the adjustment frame 2 to the best orientation angle; if not, generate a rope tightening command to control the motor 8 to drive the rotating shaft 12.

[0031] See also Figures 1 to 7 In the embodiment of the present invention, a threaded shaft 9 is coaxially fixedly connected to the output shaft of the motor 8, and a movable seat 6 is cooperatively connected to the threaded shaft 9. The movable seat 6 moves horizontally, and the movable seat 6 is used to adjust the orientation angle of the adjustment frame 2. The drive switching mechanism includes a smooth shaft 18, and the smooth shaft 18 is coaxially fixedly connected to the threaded shaft 9. The diameter of the smooth shaft 18 is the same as that of the threaded shaft 9. A disc 19 is fixedly connected to the smooth shaft 18 and is rotatably connected to the first bevel gear 10. The first bevel gear 10 rotates with the rotating shaft 12. A rebound ring plate 17 is provided on the side of the disc 19 close to the threaded shaft 9. The disc 19 and the rebound ring plate 17 are connected by a certain The multifunctional shafts 20 are connected to each other, and a plurality of return springs 21 are fixedly connected to the rebound ring plate 17. The end face of the disk 19 is provided with a plurality of circular holes, and the multifunctional shafts 20 pass through the circular holes. The outer side surface of the multifunctional shaft 20 is slidably connected with the inner side surface of the circular hole. A pointed cone 22 is provided at the end of the multifunctional shaft 20, and a plurality of limiting holes 23 are provided on the end face of the first bevel gear 10. The outer edge of the limiting hole 23 is provided with an oblique chamfer 24. A spacing is provided between the rebound ring plate 17 and the threaded shaft 9, and the spacing is smaller than the thickness value of the moving seat 6. Under the action of the return spring 21, the rebound ring plate 17 can squeeze the moving seat 6 into the threaded shaft 9. Under the driving action of the threaded shaft 9, the movable seat 6 moves toward one side of the smooth shaft 18. When the movable seat 6 slowly enters the smooth shaft 18 to squeeze the rebound ring plate 17 outward, the multifunctional shaft 20 will slowly insert into the limiting hole 23 until the movable seat 6 is disengaged from the threaded shaft 9. The movable seat 6 no longer moves, and the threaded shaft 9 continues to rotate in the same direction, thereby driving the first bevel gear 10 to rotate.

[0032] In the embodiment of the present invention, the spring plate 17 and the first bevel gear 10 are respectively located on both sides of the disc 19, the spring plate 17 is sleeved on the outer side of the smooth shaft 18, the position of the limiting hole 23 corresponds to the position of the circular hole, a plurality of limiting holes 23 and a plurality of circular holes are distributed in a circular array about the center line of the smooth shaft 18, and the chamfers 24 on adjacent limiting holes 23 contact each other, that is, the pointed cone 22 on the end of the multifunctional shaft 20 will not contact the end face of the first bevel gear 10, the pointed cone 22 will contact the chamfer 24, and under the extrusion of the pointed cone 22 and the chamfer 24, the multifunctional shaft 20 will be aligned with the limiting hole 23 until the multifunctional shaft 20 is inserted into the limiting hole 23. When the spring plate 17 is not extruded by the moving seat 6, under the action of the reset spring 21, the multifunctional shaft 20 will be separated from the limiting hole 23, and the diameter of the multifunctional shaft 20 is the same as the diameter of the limiting hole 23.

[0033] In the embodiment of the present invention, the second bevel gear 11 is coaxially fixedly connected to the rotating shaft 12, and the second bevel gear 11 is meshed with the first bevel gear 10. The support seat 13 is installed on the base frame 1, and the support seat 13 is rotatably connected to the rotating shaft 12. The center line of the rotating shaft 12 is perpendicular to the center line of the threaded shaft 9. The movable seat 6 is provided with a threaded hole and a guide hole, and the threaded shaft 9 is matched with the threaded hole. The base frame 1 is fixedly connected with a guide shaft 7, and the outer side surface of the guide shaft 7 is slidably matched with the inner side surface of the guide hole.

[0034] In the embodiment of the present invention, a pair of fixed legs 3 are hingedly connected at one end of the adjustment frame 2, and the lower ends of the fixed legs 3 are fixedly connected to the base frame 1. A pair of adjustment legs 4 are hingedly connected at the other end of the adjustment frame 2. A movable shaft 5 is rotatably connected to the adjustment leg 4, and the movable shaft 5 is connected to the movable seat 6, so that the movable seat 6 is moved to adjust the angle of the adjustment frame 2.

[0035] The working process of the embodiment of the present invention is as follows: when the orientation angle of the adjustment frame 2 is adjusted, the movable seat 6 can be moved on the threaded shaft 9. When it is necessary to control the rotation of the rotating shaft 12, the motor 8 is started to move the movable seat 6 toward one side of the smooth shaft 18. When the movable seat 6 slowly enters the smooth shaft 18 to squeeze the rebound ring plate 17 outward, the multifunctional shaft 20 will slowly insert into the limiting hole 23, and the movable seat 6 will slowly disengage from the threaded shaft 9. The threaded shaft 9 continues to rotate in the same direction. The movable seat 6 will no longer move, and the smooth shaft 18 will rotate with the first bevel gear 10, and then rotate with the rotating shaft 12. When the wind load becomes smaller, it is necessary to release the rope tightening command to reverse the threaded shaft 9. Under the action of the reset spring 21, the rebound ring plate 17 squeezes the movable seat 6 into the threaded shaft 9, and the threaded shaft 9 is reconnected with the movable seat 6.

[0036] It should be noted that when the motor 8 drives the rotating shaft 12 alone, the orientation angle of the adjusting frame 2 cannot be adjusted. When the rope 15 is tightened to resist a large wind load, the orientation angle of the adjusting frame 2 is fixed, and the optimal sun-facing angle cannot be achieved at this time. However, it is easy to understand that when the wind load is large, the weather is often bad, and the power generation brought by the photovoltaic panels at the optimal sun-facing angle and the non-optimal sun-facing angle is low, and the difference is not large. In addition, it is more important to ensure the stability of the structure at this time, and the present invention still has practical significance.
