[0025] The following description is made in conjunction with the accompanying drawings. Figure 1 - the accompanying drawings Figure 5 The application is described in further detail below.

[0026] The embodiment of the application provides a photovoltaic panel system capable of reducing wind load, which comprises a main support 10, the main support 10 is used for being connected with a foundation of a designated mounting position and is used for mounting a photovoltaic panel array formed by a plurality of photovoltaic panels, the front surface of the main support 10 has a middle mounting area 11 and a peripheral mounting area 12 for the photovoltaic panels, the peripheral mounting area 12 is sleeved outside the middle mounting area 11, and the peripheral mounting area 12 is in the same plane as the middle mounting area 11 on the front surface of the main support 10.

[0027] A plurality of fixed photovoltaic panels 20 are fixedly connected in the peripheral mounting area 12, the plurality of fixed photovoltaic panels 20 are sleeved outside the middle mounting area 11, a plurality of photovoltaic panel groups 30 are linearly arranged in the middle mounting area 11, the photovoltaic panel group 30 comprises an upper photovoltaic panel 31 and a lower photovoltaic panel 32 which are independently arranged, an included angle is formed between the upper photovoltaic panel 31 and the lower photovoltaic panel 32, the opening direction of the included angle formed by the upper photovoltaic panel 31 and the lower photovoltaic panel 32 is towards the front surface of the main support 10, and a gap is formed between the upper photovoltaic panel 31 and the lower photovoltaic panel 32.

[0028] The installation angle of the lower photovoltaic panel 32 relative to the main support 10 is adjustable, and the gap width between the upper photovoltaic panel 31 and the lower photovoltaic panel 32 is adjustable.

[0029] The application is further described in combination with a specific use scenario.

[0030] In use, an operator installs the photovoltaic panel system to a designated mounting position, in a windless state, the plurality of fixed photovoltaic panels 20 and the plurality of photovoltaic panel groups 30 on the main support 10 maintain normal states.

[0031] After the wind, the wind exerts wind load on the entire photovoltaic panel system, and the research object is limited to the front area of the main support 10. When the photovoltaic panel group 30 in the middle installation area 11 is subjected to wind load, the wind first passes through the gap between the lower photovoltaic panel 32 and the upper photovoltaic panel 31, and plays a guiding role for the wind blowing on the entire photovoltaic panel system, so that it tends to pass through the gap to pass through the entire photovoltaic panel system. When the photovoltaic panel group 30 in the middle installation area 11 is subjected to wind load, the wind load applied to the lower photovoltaic panel 32 causes the lower photovoltaic panel 32 to be offset downward, increasing the gap width between the upper photovoltaic panel 31 and the lower photovoltaic panel 32, so that more wind passes through the middle installation area 11, reducing the wind load borne by the fixed photovoltaic panel 20 in the peripheral installation area 12, and reducing the probability of damage to the entire photovoltaic panel array system.

[0032] After the wind, the wind exerts wind load on the entire photovoltaic panel system, and the research object is limited to the front area of the main support 10. When the photovoltaic panel group 30 in the middle installation area 11 is subjected to wind load, the wind first passes through the gap between the lower photovoltaic panel 32 and the upper photovoltaic panel 31, and plays a guiding role for the wind blowing on the entire photovoltaic panel system, so that it tends to pass through the gap to pass through the entire photovoltaic panel system. When the photovoltaic panel group 30 in the middle installation area 11 is subjected to wind load, the wind load applied to the lower photovoltaic panel 32 causes the lower photovoltaic panel 32 to be offset downward, increasing the gap width between the upper photovoltaic panel 31 and the lower photovoltaic panel 32, so that more wind passes through the middle installation area 11, reducing the wind load borne by the fixed photovoltaic panel 20 in the peripheral installation area 12, and reducing the probability of damage to the entire photovoltaic panel array system.

[0033] In general, the embodiment of the present application reduces the wind load applied to the photovoltaic panel array system by guiding the wind to pass through the middle of the photovoltaic panel array system. The photovoltaic panel group 30 in the middle installation area 11 can adjust the gap and the pitch angle to quickly pass the wind through the photovoltaic panel array system and reduce the wind load applied to the photovoltaic panel group 30, thereby reducing the probability of damage to the photovoltaic panel array system and improving the service life of the entire photovoltaic panel array system.

[0034] In a feasible specific implementation of the embodiment of the present application, the back of the lower photovoltaic panel 32 is provided with a rotating connecting piece 33, and the main support 10 is provided with a hinge assembly 13 for installing the lower photovoltaic panel 32. The rotating connecting piece 33 is hinged to the hinge assembly 13, and the angle between the lower photovoltaic panel 32 and the main support 10 is adjusted by the hinge between the rotating connecting piece 33 and the hinge assembly 13.

[0035] As a feasible specific embodiment of the embodiment of the present application, the back of the main support 10 is provided with a support assembly 40 for supporting the lower photovoltaic panel 32. The support assembly 40 comprises an arc-shaped sleeve 41 fixed to the back of the main support 10. An arc-shaped top rod 42 is movably inserted into the arc-shaped sleeve 41. The top of the arc-shaped top rod 42 is mounted on the back of the lower photovoltaic panel 32. A compression spring 43 is arranged in the arc-shaped sleeve 41. The two ends of the compression spring 43 are in close contact with the bottom of the inner cavity of the arc-shaped sleeve 41 and the bottom of the arc-shaped top rod 42, respectively. In this way, in a static environment without wind, the bottom of the arc-shaped top rod 42 is tightly pressed by the compression spring 43, so that the arc-shaped top rod 42 tightly presses the lower photovoltaic panel 32, thereby maintaining the relative position of the lower photovoltaic panel 32 and the main support 10. After the wind load is applied to the lower photovoltaic panel 32, the angle between the lower photovoltaic panel 32 and the main support 10 decreases, and the arc-shaped top rod 42 is retracted into the arc-shaped sleeve 41, thereby reducing the wind load borne by the lower photovoltaic panel 32. After the wind stops, the bottom of the arc-shaped top rod 42 is tightly pressed by the compression spring 43, so that the arc-shaped top rod 42 tightly presses the lower photovoltaic panel 32, thereby resetting the lower photovoltaic panel 32 and realizing the self-adaptive adjustment of the angle between the lower photovoltaic panel 32 and the main support 10.

[0036] As a feasible specific embodiment of the embodiment of the present application, the installation angle of the upper photovoltaic panel 31 and the main support 10 is adjustable. The back of the upper photovoltaic panel 31 is provided with a rotating connecting piece 33. The main support 10 is also provided with a hinged assembly 13 for mounting the upper photovoltaic panel 31. The rotating connecting piece 33 of the upper photovoltaic panel 31 is hinged to the hinged assembly 13 for mounting the upper photovoltaic panel 31. The installation angle of the upper photovoltaic panel 31 relative to the main support 10 is adjustable. In this way, when the wind generates and applies a wind load to the photovoltaic panel array system, both the upper photovoltaic panel 31 and the lower photovoltaic panel 32 can adjust the installation angle relative to the main support 10 to increase the width of the gap between the upper photovoltaic panel 31 and the lower photovoltaic panel 32, so that the wind can quickly pass through the photovoltaic panel array system, thereby reducing the wind load applied to the several fixed photovoltaic panels 20 in the peripheral mounting area 12 and reducing the probability of damage to the entire photovoltaic panel array system.

[0037] In a possible implementation of the embodiment of the present application, the back of the upper photovoltaic panel 31 is also provided with a support assembly 40 for supporting the upper photovoltaic panel 31. The bottom of the arc-shaped top rod 42 of the support assembly 40 is fixedly connected to the upper photovoltaic panel 31, and the arc-shaped sleeve 41 of the support assembly 40 is fixedly connected to the main support 10. In a windless static environment, the compression spring 43 presses against the bottom of the arc-shaped top rod 42, so that the arc-shaped top rod 42 presses against the upper photovoltaic panel 31, thereby maintaining the relative position of the upper photovoltaic panel 31 and the main support 10. After a wind load is applied to the upper photovoltaic panel 31, the angle between the upper photovoltaic panel 31 and the main support 10 decreases, the arc-shaped top rod 42 is retracted into the arc-shaped sleeve 41, and the wind load borne by the upper photovoltaic panel 31 is reduced. After the wind stops, the compression spring 43 presses against the bottom of the arc-shaped top rod 42, so that the arc-shaped top rod 42 presses against the upper photovoltaic panel 31, thereby resetting the upper photovoltaic panel 31. The angle between the upper photovoltaic panel 31 and the main support 10 is self-adaptively adjusted, and the probability of damage to the entire photovoltaic panel array system is reduced.

[0038] As a possible implementation of the embodiment of the present application, the upper photovoltaic panel 31 has an included angle with the fixed photovoltaic panel 20 installed in the peripheral installation area 12. The included angle between the upper photovoltaic panel 31 and the fixed photovoltaic panel 20 is open toward the back of the main support 10. By means of the angle between the upper photovoltaic panel 31 and the installation plane of the peripheral installation area 12, the wind blowing toward the photovoltaic array system can be guided, so that the wind is quickly collected in the middle installation area 11 and passes through the middle installation area 11. The wind load applied to the fixed photovoltaic panel 20 in the peripheral installation area 12 is reduced, and the probability of damage to the entire photovoltaic panel array system is reduced.

[0039] In a possible implementation of the embodiment of the present application, the lower photovoltaic panel 32 has an included angle with the fixed photovoltaic panel 20 installed in the peripheral installation area 12. The included angle between the lower photovoltaic panel 32 and the fixed photovoltaic panel 20 is open toward the back of the main support 10. In a windless state, the lower photovoltaic panel 32 also has an included angle with the fixed photovoltaic panel 20, like the upper photovoltaic panel 31. The wind blowing toward the photovoltaic array system can be guided, so that the wind is quickly collected in the middle installation area 11 and passes through the middle installation area 11. The wind load applied to the fixed photovoltaic panel 20 in the peripheral installation area 12 is reduced, and the probability of damage to the entire photovoltaic panel array system is reduced.
