Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and specifically relates to a photovoltaic bracket with adjustable tilt angle. Background Art

[0002] A photovoltaic bracket refers to a support structure that arranges and fixes the spacing of photovoltaic modules at a certain orientation and angle according to the specific geographical location, climate, and solar resource conditions of the construction of a photovoltaic power generation system. In desert areas with high sandstorms, although the light intensity is high, due to environmental factors, strong winds will occur. In a harsh environment of strong winds and sandstorms, when it is not conducive to the use of photovoltaic panels, strong winds will blow up sand grains and hit the surface of the photovoltaic panels, causing damage such as cracking or surface scratches to the photovoltaic panels due to the impact force. The existing photovoltaic brackets lack targeted protection mechanisms. Secondly, the power generation efficiency of fixedly installed solar photovoltaic panels is at a relatively low level, and the energy output is unstable. Traditional photovoltaic brackets usually require manual adjustment of the photovoltaic panels individually, resulting in low adjustment efficiency. To solve the above problems, the inventor proposes a photovoltaic bracket with adjustable tilt angle to solve the above problems. Summary of the Invention

Moving blocks 814 are threadedly sleeved on the outer walls of the first rotating shaft 805 and the second rotating shaft 806, and the moving blocks 814 are fixedly connected to the corresponding rack bars 813.

[0041] By adopting the above technical solution, when the first rotating shaft 805 and the second rotating shaft 806 rotate, the rack bars 813 are driven to move synchronously through the moving blocks 814.

[0042] A motor 815 is fixedly installed at the bottom of the second folding frame 4 on the right side, near one side of the corresponding first rotating shaft 805, and a second bevel gear 817 is fixedly installed at the driving end of the motor 815.

[0047] By adopting the above technical solution, the rotating adjustment frame 6 flips to drive the photovoltaic panel body 7 to flip and adjust synchronously.

[0048] Working principle: First, when the wind force of the external environment is relatively large at night and the photovoltaic panels need to be stored and protected, such as Figure 5 , Figure 8 , Figure 11 and Figure 12As shown, control the motor 815. The driving end of the motor 815 drives the right first rotating shaft 805 to rotate through the first bevel gear 816 and the second bevel gear 817. The right first rotating shaft 805 drives the right second rotating shaft 806 to rotate through the first universal coupling 809, the second universal coupling 810, the rotating shaft frame 807 and the sliding shaft 808. The right second rotating shaft 806 drives the left second rotating shaft 806 to rotate through two meshing connecting tooth frames 811. The left second rotating shaft 806 drives the left first rotating shaft 805 to rotate through the first universal coupling 809, the second universal coupling 810, the rotating shaft frame 807 and the sliding shaft 808. When the motor 815 rotates clockwise, at this time, the second rotating shaft 806 and the first rotating shaft 805 in the first folding frame 3 and the second folding frame 4 rotate synchronously and drive the moving block 814 and the rack 813 to move synchronously to the right through the thread. When the moving block 814 moves to the extreme right position, at this time, the adjusting rod 802 is driven by the rack 813, the rotating gear 812 and the driving shaft 801 to rotate counterclockwise to the horizontal position. The adjusting rod 802 drives the two adjacent rotating adjusting frames 6 to flip to the horizontal position synchronously through the synchronous frame 803. If it is necessary to adjust the inclination angle of the rotating adjusting frame 6, just drive the motor 815 to rotate counterclockwise in the reverse direction according to the same steps above. After the horizontal adjustment of the rotating adjusting frame 6 is completed, as Figure 4 As shown, control the driving end of the first electric cylinder 512 to contract. The first electric cylinder 512 drives the lifting rod 501 to move downward. The downward movement of the lifting rod 501 drives the corresponding two push rods 504 to descend synchronously through the lifting blocks 502 at both ends. The push rod 504 drives the corresponding rotating rod 505 to flip downward with the fixed plate 503 as the axis. While the rotating rod 505 flips, it drives the two first folding frames 3 on both sides of the rotating frame 2 to flip downward synchronously with the fixed block 508 as the axis through the driving rod 506 under the action of the flipping plate 509. At the same time, the driving rod 506 drives the corresponding second folding frames 4 to flip upward synchronously with the rotating connection of the first folding frames 3 as the axis, so that the first folding frames 3 and the second folding frames 4 are flipped and folded into as Figure 3 As shown, finally, control the driving end of the second electric cylinder 903 to contract and drive the rotating frame 2 to flip as Figure 2 As shown. When it is necessary to use the photovoltaic panel during the day, just operate in the reverse direction according to the above steps.
