Description

Technical Field

[0001] The present invention belongs to the technical field of flexible brackets, and particularly relates to a flexible photovoltaic bracket. Background Art

[0002] A flexible photovoltaic bracket is a relatively new type of photovoltaic support system at present. It fixes photovoltaic panels on steel strands tensioned between two columns, and the two ends are tightened by stay cables to resist the horizontal tension of the component cables. High and low columns are provided at both ends to adjust the angle of the photovoltaic panels, and swing columns are used for the intermediate support to complete the erection task. Its advantages are high clearance, large span, and low cost, and it is now widely used in highway speed bumps, green belts, toll stations, service areas, deserts, farms, fishing grounds, landfills, Gobi beaches, mountains, etc.

[0003] Due to the advantages of the flexible installation bracket being able to adapt to complex terrains and better economy, it currently occupies an important position in the entire photovoltaic power generation field.

[0070] Embodiment 2

[0071] Please refer to Figures 1 - 15 As shown, the present embodiment is a method of using a flexible photovoltaic bracket:

[0072] When it is necessary to deflect the orientation of the photovoltaic panel 6034 to the left, the first servo motor 705 is turned on to drive the winding adjusting rod 701 to rotate. At the same time, the inner adjusting rod 708 winds the inner adjusting steel strand 709 to make it shorter, thereby driving the left end of the fixed inner frame 602 of the photovoltaic module 6 to descend. The outer adjusting rod 707 relaxes the outer adjusting steel strand 709 to make it longer, facilitating the rise of the right end of the fixed inner frame 602 of the photovoltaic module 6, so that the fixed inner frame 602 rotates at an appropriate angle within the fixed outer frame 601, and the orientation of the photovoltaic panel 6034 deflects to the right;

[0073] When it is necessary to deflect the orientation of the photovoltaic panel 6034 to the right, the first servo motor 705 is turned on to drive the winding adjusting rod 701 to rotate. At the same time, the outer adjusting rod 707 winds the outer adjusting steel strand 709 to make it shorter, thereby driving the right end of the fixed inner frame 602 of the photovoltaic module 6 to descend. The inner adjusting rod 708 relaxes the inner adjusting steel strand 709 to make it longer, facilitating the rise of the left end of the fixed inner frame 602 of the photovoltaic module 6, so that the fixed inner frame 602 rotates at an appropriate angle within the fixed outer frame 601, and the orientation of the photovoltaic panel 6034 deflects to the right;

[0074] When it is necessary to adjust the orientation of the photovoltaic panel 6034 to the left front, first adjust the orientation surface of the photovoltaic panel 6034 to the left, and then turn on the second servo motor 8010 to rotate it in the reverse direction to engage the front transmission wheel 804. The transmission wheel 804 drives the driven wheel 805 to rotate. The driven wheel 805 drives the driven worm 806 to rotate. The driven worm 806 rotates to engage the winding turbine 807, so that the winding turbine 807 drives the front winding shaft 808 to rotate, simultaneously winding the two front adjusting steel strands 709, so that the main steel strand 5 gives the slider 4 an obliquely downward force, thereby driving the slider 4 to move along the arc-shaped track groove 3, so as to adjust the orientation surface of the photovoltaic panel 6034 to the left front;

[0075] When it is necessary to face the orientation of the photovoltaic panel 6034 to the left rear, first adjust the orientation surface of the photovoltaic panel 6034 to face left, and then turn on the second servo motor 8010 to make it rotate forward to engage with the rear transmission wheel 804. The transmission wheel 804 drives the driven wheel 805 to rotate. The rotation of the driven wheel 805 drives the driven worm 806 to rotate. The rotation of the driven worm 806 engages with the winding turbine 807, so that the winding turbine 807 drives the rear winding shaft 808 to rotate, and simultaneously winds the two rear adjustment steel strands 709, so that the main steel strand 5 gives the slider 4 an obliquely downward force, thereby driving the slider 4 to move along the arc-shaped track groove 3, so as to adjust the orientation surface of the photovoltaic panel 6034 to the left rear;

[0076] When it is necessary to face the orientation of the photovoltaic panel 6034 to the right front, first adjust the orientation surface of the photovoltaic panel 6034 to face right, and then turn on the second servo motor 8010 to make it rotate reversely to engage with the front transmission wheel 804. The transmission wheel 804 drives the driven wheel 805 to rotate. The rotation of the driven wheel 805 drives the driven worm 806 to rotate. The rotation of the driven worm 806 engages with the winding turbine 807, so that the winding turbine 807 drives the front winding shaft 808 to rotate, and simultaneously winds the two front adjustment steel strands 709, so that the main steel strand 5 gives the slider 4 an obliquely downward force, thereby driving the slider 4 to move along the arc-shaped track groove 3, so as to adjust the orientation surface of the photovoltaic panel 6034 to the right front;

[0077] When it is necessary to face the orientation of the photovoltaic panel 6034 to the right rear, first adjust the orientation surface of the photovoltaic panel 6034 to face right, and then turn on the second servo motor 8010 to make it rotate forward to engage with the rear transmission wheel 804. The transmission wheel 804 drives the driven wheel 805 to rotate. The rotation of the driven wheel 805 drives the driven worm 806 to rotate. The rotation of the driven worm 806 engages with the winding turbine 807, so that the winding turbine 807 drives the rear winding shaft 808 to rotate, and simultaneously winds the two rear adjustment steel strands 709, so that the main steel strand 5 gives the slider 4 an obliquely downward force, thereby driving the slider 4 to move along the arc-shaped track groove 3, so as to adjust the orientation surface of the photovoltaic panel 6034 to the right rear.

[0078] It should be further noted that one solar tracker is set and arranged on the photovoltaic module 6 in the middle position. Setting the solar tracker on the photovoltaic module 6 enables the solar tracker to change its direction as the angle of the photovoltaic module 6 changes, so that the tracking and monitoring of sunlight are more accurate; the solar tracker is electrically connected to the first servo motor 705 and the second servo motor 8010.
