Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic installation, in particular to a roof photovoltaic installation bracket with an angle adjustment structure. Background Art

[0002] The position of the sun changes with the seasons and time of day. In winter, the solar altitude angle is lower, while in summer it is higher. If the angle of the bracket is fixed, the components may receive less sunlight in winter, while in summer, direct sunlight may cause the components to overheat, affecting the power generation efficiency. By adjusting the angle of the bracket, it can be ensured that the photovoltaic components can maintain the best working condition in different seasons and different times of the day. However, the angle adjustment of existing brackets is mostly done by loosening and tightening the bolts and then rotating the angle, and then tightening the bolts after the rotation is completed. However, during the process of loosening and tightening, the angle will change due to the influence of wind or gravity, causing it to deviate from the preset angle, thereby making the angle adjustment inaccurate, and the existing parts are adjusted individually, and linkage adjustment cannot be achieved, which wastes manpower during adjustment.

[0023] It should be noted that when the utility model adjusts the angle, the positioning screw 13 is unscrewed outward so that the adjustment sleeve 3 can slide up and down on the outside of the fixed pillar 1, and the fixing box 10 is rotated by a tool. The fixing box 10 drives the driving angle adjustment wheel 12 to rotate around the rotating shaft in the middle of the U-shaped plate 8, and the U-shaped plate 8 drives the supporting bottom rod 6 to rotate. The supporting bottom rod 6 drives the adjusting sleeve 3 to slide up and down on the outside of the fixed pillar 1 through the reinforcement support rod 5. While the U-shaped plate 8 is moving, the U-shaped plate 8 drives the remaining U-shaped plates 8 to rotate through the adjusting connecting rod 9. The interlocking of the worm gear can provide a stable position locking to prevent accidental movement caused by external force or gravity. After the adjustment is completed, the positioning screw 13 is tightened to form a stable structure between the reinforcement support rod 5, the supporting bottom rod 6 and the fixed pillar 1.

The support cross bar 7 can be used to support and install the solar panels, and the two support bottom bars 6 can also be connected. Under the action of the support cross bar 7 and the adjustment connecting rod 9, adjusting one U-shaped plate 8 can drive the angle adjustment of the entire row of solar panels.

The T-shaped arc plate 15 is slidably installed in the fixed box 10, and the worm 11 is rotatably installed inside the fixed box 10. The worm 11 is meshed with the T-shaped arc plate 15 through the worm gear 14.

[0029] It should be noted that a hexagonal hole is provided at one end of the worm 11 of the utility model, and the worm 11 is driven by inserting a handle into the hexagonal hole. The worm 11 is rotated to drive the angle adjustment wheel 12 to rotate around the rotating shaft in the middle of the U-shaped plate 8, thereby driving the angle adjustment wheel 12 to drive the U-shaped plate 8 to rotate around the rotating shaft at the top of the fixed pillar 1, and the U-shaped plate 8 drives the supporting bottom rod 6 to adjust the angle.
