Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a supporting frame for photovoltaic power generation. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of semiconductor interfaces to directly convert light energy into electrical energy. It is mainly composed of three parts: solar panel components, controllers and inverters. The main components are made of electronic components. Solar cells are packaged and protected after being connected in series to form large-area solar cell modules, which are then combined with power controllers and other components to form photovoltaic power generation devices. In remote areas, photovoltaic power generation plays an important role in improving local energy supply.

[0003] An existing support frame for photovoltaic power generation (authorization announcement number: CN209072397U) has the following defects: the support frame has insufficient lateral rigidity relative to the cross beam through the upper support beam and the lower support beam. Although the swing of the photovoltaic panel is reduced in strong wind conditions, in extreme weather in high-latitude areas, strong winds mostly blow from the polar regions to low-latitude areas. When installing photovoltaic panels, they usually need to be installed tilted facing the low-latitude direction, which causes the back side of the photovoltaic panel to be subject to greater wind resistance, resulting in greater resistance to the support frame. Under the influence of long-term strong winds, the support frame is prone to a decrease in strength, thereby being damaged in extreme weather. For this reason, the present utility model is proposed.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Please refer to the attached Figure 1 -Attached Figure 4 A support frame for photovoltaic power generation, comprising a crossbeam 1, a plurality of fixed frames 2 are symmetrically hinged on the top surface of the crossbeam 1, a photovoltaic panel 3 is fixed on the top surface of the plurality of fixed frames 2, a mounting plate 4 is arranged on the bottom surface of the plurality of fixed frames 2, a movable bar 5 is hinged on the bottom surface of the plurality of mounting plates 4, a lifting plate 6 is hinged on the adjacent ends of the plurality of movable bars 5, a linkage bar 7 is fixed on the top surface of the lifting plate 6, a threaded hole is provided on the top surface of the linkage bar 7, a screw rod 8 is rotatably arranged on the top surface of the crossbeam 1, a servo motor 9 is fixed on the top surface of the crossbeam 1, an output shaft of the servo motor 9 is connected to the top end of the screw rod 8 The bottom end of the screw rod 8 is threadedly connected to the threaded hole on the top surface of the linkage bar 7. In extreme weather conditions with strong winds, the staff can start the servo motor 9 to drive the screw rod 8 to rotate, so that the linkage bar 7 threadedly connected to the screw rod 8 descends, thereby causing the lifting plate 6 to follow the decline, and then allowing several movable bars 5 that support the fixed frame 2 to be converged. When the movable bars 5 are converged, the fixed frame 2 hinged to the crossbeam 1 will drive the photovoltaic panel 3 to fold downward, thereby reducing the impact of strong winds on the photovoltaic panel 3, reducing the wind resistance of the support frame, and then reducing the damage to the support frame caused by strong winds, thereby extending the service life of the support frame.

[0022] In the embodiment, a first gear 10 is sleeved and fixed on one end of the beam 1, a second gear 11 is arranged below the first gear 10, a toothed belt 12 is meshed between the first gear 10 and the second gear 11, a driving motor 13 is arranged on one side of the second gear 11, and the output shaft of the driving motor 13 is fixed to the inside of the second gear 11. The second gear 11 is driven by the driving motor 13 to rotate, and the second gear 11 is transmitted to the first gear 10 through the toothed belt 12. When the first gear 10 rotates, it will drive the beam 1 to rotate, so that the staff can adjust the inclination angle of the photovoltaic panel 3 according to the direct angle of sunlight in different regions, thereby improving the power generation efficiency of the photovoltaic panel 3.

[0023] In the embodiment, support plates 14 are movably provided at both ends of the beam 1, a base 15 is fixed to the bottom surface of the support plate 14, and the drive motor 13 is fixed to the base 15. A protective shell 16 is provided at one end of the beam 1, and the bottom surface of the protective shell 16 is fixed to the top surface of the base 15. The first gear 10, the second gear 11, the toothed belt 12 and the drive motor 13 are all located inside the protective shell 16. The base 15 is cast in precast concrete. In actual operation of the support frame, the base 15 and the support plate 14 can provide good support for it. In severe weather outdoors, the protective shell 16 can protect its internal gear parts to prevent external wind and sand from entering the shell and causing damage to the parts.

[0024] In the embodiment, a plurality of adjustment holes 17 are provided on the top surface of the fixing frame 2, and the fixing frame 2 is fixed to the mounting plate 4 by bolts and nuts. Limiting plates 18 are fixed on both sides of the lifting plate 6, and the top surface of the limiting plate 18 is in contact with the bottom surface of the movable bar 5. The staff can control the position of the mounting plate 4 in the different adjustment holes 17 at the bottom of the fixing frame 2, and can adjust the angle between the two movable bars 5, so as to control the folding amplitude of the fixing frame 2. When the screw rod 8 rotates to drive the lifting plate 6 to rise, the movable bar 5 switches from contraction to expansion, and the limiting plate 18 can limit the movable bar 5 on both sides to prevent the movable bar 5 from being excessively expanded.

[0025] Working principle: Under strong wind and extreme weather conditions, the staff can start the servo motor 9 to drive the screw rod 8 to rotate, so that the linkage bar 7 threadedly connected to the screw rod 8 will descend, so that the lifting plate 6 will follow the decline, and then the several movable bars 5 that support the fixed frame 2 will be converged. When the movable bars 5 are converged, the fixed frame 2 hinged to the crossbeam 1 will drive the photovoltaic panel 3 to fold downward, thereby reducing the impact of strong wind on the photovoltaic panel 3. When the extreme weather is over, the staff starts the servo motor 9 to drive the screw rod 8 to reverse, and the screw rod 8 reverses to make the lifting plate 6 rise, and the several movable bars 5 switch from convergence to expansion, limiting The positioning plate 18 limits the movable bar 5 on both sides thereof. When the movable bar 5 is opened, the fixing frame 2 and the photovoltaic panel 3 will be stretched open again, and the photovoltaic panel 3 will work normally. When the staff needs to adjust the inclination angle of the photovoltaic panel 3 according to the different light in different areas, the staff starts the driving motor 13 to drive the second gear 11 to rotate, and the second gear 11 is transmitted to the first gear 10 through the toothed belt 12. When the first gear 10 rotates, it will drive the crossbeam 1 to rotate. The rotation of the crossbeam 1 will cause the inclination angle of the fixing frame 2 and the photovoltaic panel 3 above it to follow the change, thereby realizing the adjustment of the inclination angle of the photovoltaic panel 3.

[0026] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
