Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

Therefore, they should not be construed as limitations on this utility model.

[0023] like Figures 1-3 As shown in the figure, the rotating photovoltaic panel with anti-hail function described in this specific embodiment includes a rotating shaft 4 installed on the left and right ends of the top of the photovoltaic support 1. Each rotating shaft 4 has a first bearing installed at both ends, and the two first bearings are installed at both ends of the left and right ends of the top of the photovoltaic support 1.

[0024] Photovoltaic panels 3 are respectively provided on the inner ends of the two rotating shafts 4. The inner ends of the two photovoltaic panels 3 are placed on the longitudinal spring support plates 9. The two longitudinal spring support plates 9 are respectively installed on the top two sides of the vertical plate 8. The vertical plate 8 is installed on the middle horizontal bar of the H-shaped bracket 10 in the lower part of the photovoltaic bracket 1.

[0025] A motor mechanism 5 is installed on the left side of the front top of the photovoltaic bracket 1 to drive the left photovoltaic panel 3 of the photovoltaic bracket 1 to rotate downward; a transmission mechanism 6 is installed on the right side of the rear top of the photovoltaic bracket 1 to drive the right photovoltaic panel 3 of the photovoltaic bracket 1 to rotate downward; the motor mechanism 5 synchronously drives the transmission mechanism 6 to operate.

[0026] In this design, the top of the vertical plate 8 is slightly lower than the horizontal plane where the bottom surface of the photovoltaic panel 3 is located. This facilitates the installation of the intermediate linkage shaft of the motor mechanism 5.

[0027] Furthermore, the motor mechanism 5 includes a first gear 56 at the front end of a rotating shaft 4 mounted on the left side of the photovoltaic bracket 1. The first gear 56 is connected to a second gear 51 via a first chain 54. The second gear 51 is connected to the front end of an intermediate linkage shaft 57, and second bearings are installed at both ends of the intermediate linkage shaft 57. The second gear 51 is connected to the shaft of a motor 52. The motor 52 is mounted on a motor base plate 53, which is mounted on the upper middle part of the front end of the photovoltaic bracket 1.

[0028] Furthermore, a first lower frame-type protective cover 55 is installed on the motor mechanism 5.

[0029] Furthermore, the transmission mechanism 6 includes a third gear 66 mounted on the rear end of the intermediate linkage shaft 57, the third gear 66 meshing with a fourth gear 65, the fourth gear 65 mounted on a third bearing, the third bearing mounted on the right side of the rear top of the photovoltaic bracket 1; the fourth gear 65 is connected to a fifth gear 61 via a second chain 63; the fifth gear 61 is mounted on the rear end of the rotating shaft 4 on the right side of the photovoltaic bracket 1.

[0030] Furthermore, a second lower frame-type protective cover 62 is installed on the transmission mechanism 6.

[0031] Furthermore, position sensors 2 are respectively installed on the lower parts of the left and right ends of the photovoltaic bracket 1.

[0032] Furthermore, a PLC controller 11 is installed at the front of the first lower frame protective cover 55, and a wireless module 12 is installed on the left side of the PLC controller 11; a solar panel 13 is installed on the upper left side of the photovoltaic bracket 1.

[0033] The solar module 13 in this design includes modules (photovoltaic panels), lithium batteries, an energy storage inverter, a smart meter, a power grid, grid-connected loads, and off-grid loads. The energy storage inverter enables bidirectional DC-AC conversion for battery charging and discharging. This system has a high degree of integration, effectively reducing installation time and cost. The above structure is known technology, therefore it will not be described in detail in this application.

[0034] Furthermore, a short vertical guard plate 7 is provided on the top of the rotating shaft 4, and the short vertical guard plate 7 is perpendicular to the photovoltaic panel 3 on its inner end edge.

[0035] Furthermore, the longitudinal spring support plate 9 includes a U-shaped frame 93 mounted on the top side of the vertical plate 8, a short shaft 92 mounted on the U-shaped frame 93, a hinge spring mounted on the shaft of the short shaft 92, and an outer support plate 91 for the short shaft 92, the outer side of which is an arc end. The structure of the longitudinal spring support plate 9 in this design is similar to that of existing spring hinge structures.

[0036] The working principle of this utility model is explained in detail below;

[0037] In this design, a PLC controller 11 is installed at the front of the first lower frame protective cover 55, and a wireless module 12 is installed on the left side of the PLC controller 11. When extreme weather is forecast, the photovoltaic panel maintenance personnel can immediately control the PLC controller 11 through the wireless module 12. The PLC controller 11 is powered by the solar energy collected by the photovoltaic panel.

[0038] The PLC controller 11 controls the motor to work, driving the second gear 51 to rotate to the right. The first chain 54 drives the first gear 56 to rotate to the right, which in turn drives the rotating shaft on the left side of the photovoltaic bracket 1 to rotate to the right. This causes the photovoltaic panel 3 on the left side of the photovoltaic bracket 1 to flip downwards. When the panel reaches the inner left wall of the photovoltaic bracket 1, the position sensor 2 detects the position and controls the motor to stop working.

[0039] Simultaneously, when the motor is working, it drives the second gear 51 to drive the intermediate linkage shaft 57, which in turn drives the third gear 66 to rotate to the right. The third gear 66 and the fourth gear 65 drive the fourth gear 65 to rotate to the left. The fourth gear 65 drives the fifth gear 61 to rotate to the left via the second chain 63, which in turn drives the rotating shaft on the right side of the photovoltaic bracket 1 to rotate to the left. When the photovoltaic bracket 1 reaches the inner wall on the right side, the position sensor 2 detects the position and controls the motor to stop working.

[0040] In this design, when the motor is working, it can synchronously drive the two photovoltaic panels 3 to flip downwards onto the inner walls of the left and right sides of the photovoltaic bracket 1, forming a 90-degree downward flip. At the same time, it drives the vertical guard plates 4 on the two rotating shafts to rotate 90 degrees inwards. Since the short vertical guard plate 7 is perpendicular to the photovoltaic panel 3 on its inner edge, and the vertical guard plate 4 is horizontally set on the left and right sides of the top surface of the photovoltaic bracket 1, the two short vertical guard plates 7, after being flipped 90 degrees, are horizontal in hail weather, thus protecting the photovoltaic panels 3 on the inner walls of the left and right sides of the photovoltaic bracket 1.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
