[0012] The beneficial effects of the present invention compared to the prior art are: 1. The photovoltaic panel mounting structure of the present invention can relieve strong wind pressure, which is reflected in the following: the photovoltaic panel transfers the wind load to the second frame, forming an exhaust space between the free end of the second frame and the opposite end of the first frame. This exhaust space is formed on the sunny side and the shady side of the airway. Even if the sunny side and the shady side of the photovoltaic panel mounting structure are connected, strong winds are discharged to the sunny side of the roof through the exhaust space. Strong winds that still blow on the photovoltaic panels of the first frame will eventually enter the exhaust space and be discharged to the sunny side of the roof under the action of the inclination of the photovoltaic surface, thereby reducing the wind load on the photovoltaic panel mounting structure and reducing safety hazards when strong winds invade. In order to unload strong winds, the photovoltaic panels are arranged in two parts, one part is installed on the first frame and the other part is installed on the second frame. After unloading and the strong wind is degraded, the drive plate drives the second frame to rotate upward, so that the two parts of the photovoltaic panels are displayed on the same sunny side and absorb light normally.

[0013] 2. The photovoltaic rack assembly also includes a secondary pressure relief component, which is arranged on rack No. 1 and rack No. 2; as the exhaust space opens, the secondary pressure relief component is also deflected relative to the back side of rack No. 1 toward the sunny side of the roof. At this time, the secondary pressure relief component is intercepted on the air outlet end of the exhaust space, and is also intercepted on the back side of rack No. 1, that is, intercepted on the back side of the photovoltaic panel on rack No. 1. At this time, when the strong wind is discharged through the exhaust space toward the sunny side of the roof through pressure relief, most of it is intercepted by the secondary pressure relief component and blown back to the back of the photovoltaic panel on rack No. 1. It is released toward the low side of the sunny side of the roof under the guidance of the secondary pressure relief component and the back of the photovoltaic panel, which not only enables the strong wind to be quickly downgraded and unloaded, but also enables the strong wind to be discharged reasonably, thereby reducing the damage to the roof caused by the strong wind, and the pressure relief structure is more reasonable.

DETAILED DESCRIPTION

[0016] The above and other embodiments and advantages of the present invention are clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments.

[0017] In one embodiment, Figures 1-8 As shown: This embodiment provides a photovoltaic panel mounting structure, including a base 10, a mounting frame 20, a photovoltaic frame assembly 30 and a driving mechanism 40. The mounting frame 20 is mounted on the base 10. The photovoltaic frame assembly 30 includes a first frame 310 and a second frame 320 arranged on the mounting frame 20. The driving mechanism 40 includes a driving plate 410 mounted on the mounting frame 20. The action end of the driving plate 410 is connected to the second frame 320; the driving plate 410 drives the second frame 320 away from the mounting frame 20. When the No. 1 frame 310 is rotated, an exhaust space 330 with a pressure relief function is formed between the No. 2 frame 320 and the No. 2 frame 320. An air duct 220 is opened in the mounting frame 20. The air duct 220 is a rectangular opening opened on the back of the mounting frame 20, and the air duct 220 is located on the back side of the No. 2 frame 320. When the No. 2 frame 320 rotates through the rotating shaft, it reaches the back side of the mounting frame 20 through the air duct 220. The inlet and outlet ends of the air duct 220 are connected to the inlet and outlet ends of the exhaust space 330.

[0018] In this embodiment, the photovoltaic panel mounting structure is usually installed on a building for use, for example Figure 6On the roof shown, in most cases, in order to improve the photovoltaic absorption rate, the photovoltaic panels are placed on the sunny side with better light when the photovoltaic panel mounting structure is installed. This makes the sunny side P of the roof blocked by the back of the photovoltaic panel mounting structure. Once a strong wind hits the photovoltaic panel, the photovoltaic panel is fixed in the prior art, so the photovoltaic panel bears most of the wind load and transfers the wind load to the entire photovoltaic rack, posing a safety hazard. The photovoltaic panel mounting structure of the present invention can relieve the pressure of strong winds, which is reflected as follows: the photovoltaic panel transfers the wind load to the second rack 320, and the drive plate 410 drives the second rack 320 to press Figure 5 As shown, it deflects downward (toward the sun-facing side), and at this time, an exhaust space 330 is formed between the free end of the second frame 320 and the opposite end of the first frame 310. This exhaust space 330 is formed on the sunny side and the sun-facing side of the air duct 220. Even if the sunny side and the sun-facing side of the photovoltaic panel mounting structure are connected, strong winds are discharged to the sunny side P of the roof through the exhaust space 330. Strong winds that still blow onto the photovoltaic panels of the first frame 310 will eventually enter the exhaust space 330 and be discharged to the sunny side P of the roof under the action of the inclination of the photovoltaic surface, thereby reducing the wind load on the photovoltaic panel mounting structure (also called photovoltaic bracket in the prior art) and reducing safety hazards when strong winds invade. In order to unload the photovoltaic panels during strong winds, the photovoltaic panels are divided into two parts, one part is installed on the No. 1 frame 310, and the other part is installed on the No. 2 frame 320. After unloading and the strong wind is reduced, the driving plate 410 drives the No. 2 frame 320 to rotate upward (toward the sun), so that the two parts of the photovoltaic panels are displayed on the same sunny side and absorb light normally.

[0019] In this embodiment, the photovoltaic rack assembly 30 further includes a secondary pressure relief assembly 340, which is provided on the first rack 310 and the second rack 320; as the exhaust space 330 is opened (the second rack 320 carries the photovoltaic panels), the second pressure relief assembly 340 is provided on the first rack 310 and the second rack 320; Figure 5 The shape shown is deflected downward (toward the sun-facing side), and the secondary pressure relief component 340 is also deflected relative to the back side of the No. 1 frame 310 toward the sun-facing side P of the roof. At this time, the secondary pressure relief component 340 is intercepted on the air outlet end of the exhaust space 330, and is also intercepted on the back side of the No. 1 frame 310, that is, intercepted on the back side of the photovoltaic panel on the No. 1 frame 310. At this time, when the strong wind is discharged through the exhaust space 330 toward the sun-facing side P of the roof through the exhaust space 330, most of it is intercepted by the secondary pressure relief component 340 and blown back to the back of the photovoltaic panel on the No. 1 frame 310. It is released toward the low side of the sun-facing side P of the roof under the guidance of the secondary pressure relief component 340 and the back of the photovoltaic panel, which not only enables the strong wind to be quickly downgraded and unloaded, but also enables the strong wind to be discharged reasonably, thereby reducing the damage to the roof caused by the strong wind, and the pressure relief structure is more reasonable.

[0020] like Figure 1 、 Figure 2As shown, the mounting frame 20 has a rectangular frame. Considering that the No. 1 frame 310 and the No. 2 frame 320 have a reasonable storage installation space, a rectangular assembly cavity 201 is provided in the frame of the mounting frame 20. Considering that the No. 1 frame 310 is fixed and the No. 2 frame 320 can rotate relative to the No. 1 frame 310 to achieve wind unloading, the No. 1 frame 310 is fixedly arranged in the assembly cavity 201, and the No. 2 frame 320 is transferred in the assembly cavity 201 by means of a rotating shaft or a hinged seat. The free end of the No. 2 frame 320 is close to the No. 1 frame 310, and the photovoltaic panel 50 is respectively installed in two parts on the No. 1 frame 310 and the No. 2 frame 320.

[0021] like Figures 1 to 3 as well as Figure 5 、 Figure 6 As shown, taking into account the maximum light absorption rate of the photovoltaic surface, only the mounting frame 20 in the photovoltaic panel mounting structure is embodied, one end of which is tilted downward and the other end is tilted upward. The low end of the No. 1 frame 310 is close to the low end of the mounting frame 20, and the high end of the No. 1 frame 310 is close to two-thirds of the assembly cavity 201 and is fixed; taking into account the reason that when the sunny side of the photovoltaic surface is hit by strong winds, it is impacted from the low side to the high side, so the high end of the No. 2 frame 320 on the high side is transferred to the high end of the mounting frame 20, the low end of the No. 2 frame 320 is close to the high end of the No. 2 frame 320 and is hinged with a connecting rod, the free end of the connecting rod extends to the outside of the mounting frame 20 and is hinged to the action end of the drive plate 410, and the connecting rod increases the driving stroke of the drive plate 410 to meet the effective deflection of the No. 2 frame 320.

[0022] Considering that the second frame 320 realizes automatic deflection, Figure 3 、 Figure 5 as well as Figure 7As shown, the driving mechanism 40 also includes an electric cylinder 420 and a pressure sensor 430 fixed to the side wall of the mounting frame 20, and also includes a sensing base 440 installed on the side wall of the mounting frame 20. The sensing base 440 is provided with a movable hole 4401, and a stepped portion 4402 is provided in the movable hole 4401. The movable hole 4401 and the sensing end of the pressure sensor 430 are in the same straight line. A sensing rod 4403 is provided in the movable hole 4401, and one end of the sensing rod 4403 extends to the outer end of the movable hole 4401 close to the pressure sensor 430. The other end of the sensing rod 4403 extends to the other outer end of the movable hole 4401 and is provided with a sensing cover 4404. The outer end of the sensing cover 4404 is bent toward the photovoltaic surface of the photovoltaic panel 50 and is parallel to the photovoltaic surface of the photovoltaic panel 50. A spring 4405 is sleeved on the sensing rod 4403, and the spring 4405 is located in the movable hole 4401. A propulsion part 440301 is provided on the sensing rod 4403, and one end of the spring 4405 elastically abuts against the propulsion part 440301, and the other end elastically abuts against the step part 4402. When strong winds blow toward the photovoltaic panel 50, they will undoubtedly also blow toward the sensor cover 4404. The impact on the sensor cover 4404 pushes the sensor rod 4403 downward along the movable hole 4401. The sensor rod 4403 is equipped with a propulsion unit. As the sensor rod 4403 descends, the propulsion unit 440301 pushes the spring 4405, compressing and shortening the spring 4405. The bottom end of the sensor rod 4403 contacts the sensing end of the pressure sensor 430. The pressure sensor 430 senses a signal and feeds it back to the photovoltaic system's control module. The control module controls the electric cylinder 420, which pushes the drive plate 410. The drive plate 410 drives the second frame 320, which then deflects the photovoltaic panel 50 toward the sunny side P of the roof, achieving automation. It is worth noting that the control module is an existing component in photovoltaic systems. Photovoltaic systems often require a power storage module and a controller module, and the prior art will not be discussed further.

[0023] like Figure 3 、 Figure 5 as well as Figure 8As shown, the back of the mounting frame 20 is hinged with a first guide seat 230 from the lower end, the secondary pressure relief assembly 340 includes a first pressure relief plate 3401 slidably assembled in the first guide seat 230, and the back of the second frame 320 is installed with a second guide seat 3201. The secondary pressure relief assembly 340 also includes a second pressure relief plate 3402 slidably assembled in the second guide seat 3201. One end of the first pressure relief plate 3401 and the second pressure relief plate 3401 reaches the back side of the airway 220 and is flexibly connected together. A pressure relief port 2301 is provided at the lower end of the first guide seat 230, and a pressure relief cavity 3403 is opened on the first pressure relief plate 3401 and the second pressure relief plate 3402, and the pressure relief cavity 3403 is in gas communication with the pressure relief port 2301. When the second frame 320 deflects the photovoltaic panel 50 above toward the sunny side P of the roof, it also deflects the second guide seat 3201 toward the sunny side P of the roof. The second guide seat 3201 drives the second pressure relief plate 3402 to deflect toward the sunny side P of the roof. The flexible connection relationship of the second pressure relief plate 3402 drives the second pressure relief plate 3402 to deflect toward the sunny side P of the roof. The second pressure relief plate 3402 drives the first guide seat 230 to deflect toward the sunny side P of the roof. At this time, the secondary pressure relief assembly 340 is blocked on the air outlet end of the exhaust space 330. At the same time, it is also intercepted on the back side of the No. 1 frame 310, that is, on the back side of the photovoltaic panel on the No. 1 frame 310. When the strong wind is discharged through the exhaust space 330 to the sunny side P of the roof, most of it is intercepted by the secondary pressure relief component 340 and enters the pressure relief chamber 3403. Then, it is blocked by the back side of the photovoltaic panel 50 on the No. 1 frame 310, and finally released toward the low side of the sunny side P of the roof through the pressure relief port 2301 on the low side, thereby achieving the purpose of unloading the strong wind and quickly releasing the strong wind from the sunny side P of the roof toward the low side.

[0024] The present invention further provides a photovoltaic panel assembly, including a controller 60 mounted on the back of the second frame 320 , wherein the controller 60 is provided with a control module, and the control module is electrically connected to the pressure sensor 430 and the electric cylinder 420 .

This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures.
