Description

Technical Field

[0001] This utility model relates to the field of solar photovoltaic panels, specifically to a roof structure for an adjustable-angle solar photovoltaic panel. Background Technology

[0002] Solar power generation is a new type of renewable energy, and solar energy resources are inexhaustible. Because solar energy is widely distributed across the Earth, distributed solar photovoltaic power stations can be used as long as there is sunlight, without being limited by factors such as region or altitude. Therefore, as photovoltaic power generation and solar panel manufacturing technologies have become more sophisticated, rooftop solar photovoltaic power generation technology has been widely adopted. Rooftop solar photovoltaic power generation itself does not use fuel, emits no substances including greenhouse gases and other waste gases, does not pollute the air, and does not generate noise. It is a green and environmentally friendly new type of renewable energy. Solar photovoltaic rooftops achieve energy conservation and emission reduction goals by installing solar power generation devices on the roof of buildings.

[0003] Traditional photovoltaic (PV) panels are laid flat during power generation. In windy weather, their large surface area makes them susceptible to being blown over. During hailstorms, hailstones directly impact the panel surface, causing damage. Furthermore, the fixed angle at which the PV panels are mounted on the roof affects their power generation efficiency. Therefore, new technical solutions are needed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a roof structure for an adjustable-angle solar photovoltaic panel. This solves the technical problems that when photovoltaic panels are generating electricity, they are in a flat state, and in windy weather, the large wind-exposed area makes them easy to be blown over. In hail weather, hail directly hits the surface of the photovoltaic panel, which easily damages the surface.

[0005] To achieve the objective of this utility model, the technical solution adopted is as follows: A roof structure for an adjustable-angle solar photovoltaic panel is designed, comprising: A support mechanism, comprising two parallel base plates, each with a column welded to the center of its surface; A folding mechanism includes two U-shaped frames rotatably mounted between two columns via a pivot. A first photovoltaic panel, a second photovoltaic panel, a third photovoltaic panel, and a fourth photovoltaic panel are arranged on the inner side of each U-shaped frame. These photovoltaic panels are sequentially hinged together. Slide grooves are provided on both sides of the inner cavity of each U-shaped frame, and four sliders are slidably connected within these grooves. The two ends of each of the first, second, third, and fourth photovoltaic panels are rotatably connected to the sliders via connecting shafts. A first lead screw is rotatably connected within the slide grooves via bearings. A slider connected to the fourth photovoltaic panel is threaded onto the outside of the lead screw. A first drive motor is mounted at one end of each U-shaped frame, and the drive end of the first drive motor rotatably passes through the U-shaped frame and is connected to the first lead screw via a coupling.

[0006] Preferably, the system further includes an angle adjustment mechanism, which includes adjustment slots at opposite ends of the two columns. Adjustment blocks are slidably connected in each adjustment slot. The U-shaped frame is rotatably connected to the adjustment blocks via a connecting shaft. A second lead screw is rotatably connected to the adjustment slot on one side of the column via a bearing. The adjustment block is threaded onto the outside of the second lead screw. A second drive motor is mounted on the surface of the column. The drive end of the second drive motor rotatably passes through the column and is connected to the second lead screw via a coupling. A horizontal limiting mechanism is provided between the U-shaped frame and the base plate.

[0007] Preferably, the horizontal limiting mechanism includes guide grooves formed at opposite ends of the two base plates, and guide blocks are slidably connected in both guide grooves. The guide blocks are rotatably connected to the U-shaped frame via a connecting shaft.

[0008] Preferably, the hinges connecting the first and second photovoltaic panels and the third and fourth photovoltaic panels are both located on the upper surface, while the hinge connecting the second and third photovoltaic panels is located on the lower surface.

[0009] Preferably, the centers of gravity of the first photovoltaic panel and the third photovoltaic panel are close to the side of the second photovoltaic panel and the fourth photovoltaic panel, respectively, and the centers of gravity of the second photovoltaic panel and the fourth photovoltaic panel are close to the first photovoltaic panel and the third photovoltaic panel, respectively.

[0010] Preferably, both the first lead screw and the second lead screw are fitted with telescopic bellows on their outer sides.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model combines a first drive motor, a U-shaped frame, a slide rail, a slider, a first lead screw, a first photovoltaic panel, a second photovoltaic panel, a third photovoltaic panel, and a fourth photovoltaic panel. In windy or hailous weather, the personnel controller activates the first drive motor, which in turn drives the first lead screw to rotate. Because the slider on the fourth photovoltaic panel is threaded onto the outside of the first lead screw, it moves the fourth photovoltaic panel towards the third photovoltaic panel. This, combined with a hinge, allows the first, second, third, and fourth photovoltaic panels to fold. Once folded (e.g., ...), the folded structure... Figure 5 As shown in the figure, the surfaces of the first, second, third, and fourth photovoltaic panels are folded inward, thereby reducing the area of ​​the photovoltaic panels during windy weather. At the same time, it avoids damage to the surface of the photovoltaic panels from hail, further reducing the economic losses of the photovoltaic panels under severe weather conditions.

[0012] 2. This utility model combines a second drive motor, a second lead screw, an adjusting groove, an adjusting block, and a horizontal limiting mechanism. When the photovoltaic panel is in use, starting the second drive motor drives the second lead screw to rotate, which, in conjunction with the horizontal limiting mechanism, adjusts the tilt angle of the photovoltaic panel. This allows the angle of the photovoltaic panel to be adjusted in a timely manner according to the sunlight conditions, further improving the power generation efficiency of the photovoltaic panel. Furthermore, in windy weather, the tilt angle of the U-shaped frame is reduced by adjusting the second drive motor, thereby lowering the height of the folded photovoltaic panel and lowering its center of gravity, further improving the wind resistance of the folded photovoltaic panel.

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments: Example 1: A roof structure for an adjustable-angle solar photovoltaic panel, see [link / reference] Figures 1 to 5 The system includes: a support mechanism comprising two parallel base plates 1, each with a column 11 welded to its center; and a folding mechanism comprising two U-shaped frames 2 rotatably mounted between the two columns 11 via a pivot, wherein a first photovoltaic panel 21, a second photovoltaic panel 22, a third photovoltaic panel 23, and a fourth photovoltaic panel 24 are mounted on the inner side of each U-shaped frame 2. The first photovoltaic panel 21, the second photovoltaic panel 22, the third photovoltaic panel 23, and the fourth photovoltaic panel 24 are sequentially hinged together, with the hinges connecting the first photovoltaic panel 21 and the second photovoltaic panel 22, and the hinges connecting the third photovoltaic panel 23 and the fourth photovoltaic panel 24, both located on the upper surface. The hinge connecting the second photovoltaic panel 22 and the third photovoltaic panel 23 is located on the lower surface. Both sides of the inner cavity of the U-shaped frame 2 are provided with sliding grooves 26. Four sliders 28 are slidably connected in the sliding grooves 26. The two ends of the first photovoltaic panel 21, the second photovoltaic panel 22, the third photovoltaic panel 23 and the fourth photovoltaic panel 24 are rotatably connected to the sliders 28 through connecting shafts. The first lead screw 27 is rotatably connected in the sliding grooves 26 through bearings. The slider 28 connected to the fourth photovoltaic panel 24 is threaded on the outside of the lead screw. A first drive motor 25 is installed at one end of the U-shaped frame 2. The drive end of the first drive motor 25 rotates through the U-shaped frame 2 and is connected to the first lead screw 27 through a coupling.

[0016] During operation, the first photovoltaic panel 21, the second photovoltaic panel 22, the third photovoltaic panel 23, and the fourth photovoltaic panel 24 are laid out to generate electricity. In windy or hailous weather, the personnel controller activates the first drive motor 25 (the control method is existing technology and will not be described further). The first drive motor 25 then drives the first lead screw 27 to rotate. Since the slider 28 on the fourth photovoltaic panel 24 is threaded onto the outside of the first lead screw 27, it moves the fourth photovoltaic panel 24 towards the third photovoltaic panel 23. This, combined with the hinge, allows the first photovoltaic panel 21, the second photovoltaic panel 22, the third photovoltaic panel 23, and the fourth photovoltaic panel 24 to fold. Once folded (e.g., ...), the photovoltaic panels fold together. Figure 5 As shown in the diagram, the surfaces of the first photovoltaic panel 21, the second photovoltaic panel 22, the third photovoltaic panel 23, and the fourth photovoltaic panel 24 are folded inwards, thereby reducing the area of ​​the photovoltaic panels during windy weather. Simultaneously, this avoids damage to the surface of the photovoltaic panels from hail, further reducing economic losses due to severe weather conditions. For details, see Figure 1 , Figure 5The system also includes an angle adjustment mechanism, which comprises adjustment grooves 33 located at opposite ends of the two columns 11. Adjustment blocks 34 are slidably connected within each adjustment groove 33. The U-shaped frame 2 is rotatably connected to the adjustment blocks 34 via a connecting shaft. A second lead screw 35 is rotatably connected to the adjustment groove 33 on one side of the column 11 via a bearing. The adjustment blocks 34 are threaded onto the outside of the second lead screw 35. A second drive motor 36 is mounted on the surface of the column 11. The drive end of the second drive motor 36 rotatably passes through the column 11 and is connected to the second lead screw 35 via a coupling. A horizontal limiting mechanism is provided between the U-shaped frame 2 and the base plate 1. The horizontal limiting mechanism includes guide grooves 3 located at opposite ends of the two base plates 1. Guide blocks 31 are slidably connected within each guide groove 3. The guide blocks 31 are rotatably connected to the U-shaped frame 2 via a connecting shaft. When the photovoltaic panel is in use, the second drive motor 36 is activated to drive the second lead screw 35 to rotate forward or backward, thereby causing the adjusting block 34 to move upward or downward (the upward or downward movement of the adjusting block 34 is achieved by the forward and reverse rotation of the first drive motor 25, and how the motor achieves forward and reverse rotation is a well-known technology, which will not be elaborated here). This causes one end of the U-shaped frame 2 to move upward or downward, and then cooperates with the guide block 31 to slide within the guide groove 3, thereby adjusting the tilt angle of the photovoltaic panel during use. This allows the angle of the photovoltaic panel to be adjusted in a timely manner according to the sunshine conditions, further improving the power generation efficiency of the photovoltaic panel. In windy weather, the tilt angle of the U-shaped frame 2 is reduced by adjusting the second drive motor 36, thereby reducing the height of the folded photovoltaic panel and lowering the center of gravity of the folded photovoltaic panel, further improving the wind resistance of the folded photovoltaic panel.

[0017] Further, see Figure 3 The centers of gravity of the first photovoltaic panel 21 and the third photovoltaic panel 23 are close to the side of the second photovoltaic panel 22 and the fourth photovoltaic panel 24, respectively. The centers of gravity of the second photovoltaic panel 22 and the fourth photovoltaic panel 24 are close to the first photovoltaic panel 21 and the third photovoltaic panel 23, respectively. When folded, the first photovoltaic panel 21, the second photovoltaic panel 22, the third photovoltaic panel 23 and the fourth photovoltaic panel 24 have a tendency to fold towards the hinge joint, which facilitates the rotation of the first lead screw 27 to drive the photovoltaic panels to move and fold.

[0018] It is worth noting that, see Figure 5 The first lead screw 27 and the second lead screw 35 are both fitted with telescopic corrugated tubes 32. The telescopic corrugated tubes 32 can protect the first lead screw 27 and the second lead screw 35, and prevent the first lead screw 27 and the second lead screw 35 from being corroded, which would affect the folding and angle adjustment of the photovoltaic panel.
