Abstract
Description
Technical Field
[0001] This application relates to the technical field of photovoltaic equipment, and particularly relates to a photovoltaic panel with an adjustable tilt angle that can adapt to changes. Background Art
[0002] In high-latitude regions, a larger tilt angle of the photovoltaic panel is required to ensure power generation. However, a larger tilt angle means that the wind load on the photovoltaic panel will increase, and setting the photovoltaic panel at a higher angle will also increase the material used for the bracket below the photovoltaic panel, further increasing the construction cost. In the prior art, additional brackets and fixing devices are usually used to reinforce the photovoltaic panel, which increases the total installation cost of the photovoltaic system and has additional requirements for the bearing capacity of the installation foundation, and the versatility is not high. Summary of the Utility Model
[0003] In view of the deficiencies in the prior art, this application provides a photovoltaic panel with an adjustable tilt angle that can adapt to changes. By using a limiting component and an adjustable angle of the photovoltaic panel body, the photovoltaic panel body can avoid and relieve the instantaneous wind load by changing its angle relative to the ground, and at the same time can reduce the subsequent wind load, without the need for additional reinforcement of the photovoltaic panel body, reducing the construction cost, lowering the requirements for the installation foundation, and reducing the probability of damage to the photovoltaic panel body.

[0008] The photoelectric conversion board is installed on the connecting frame through the backboard. The angle between the photovoltaic panel body and the mounting frame is adjustable. The bottom of the backboard has an extension section, and the extension section extends into the limiting component;
[0009] When the photovoltaic panel body is subjected to wind load, the change in the angle between the photovoltaic panel body and the mounting frame forces the shape of the elastic body to change.

The elastic body is located in the limiting area and is fixedly connected to one of the limiting frames. In the absence of wind load, the elastic body presses against the extension section to make the extension section closely adhere to one of the limiting frames away from the elastic body.
[0012] Optionally, the elastic body is a spring piece.
[0013] Optionally, a buffer strip is installed on the limiting frame away from the limiting frame where the elastic body is installed. In the absence of wind load, the extension section closely adheres to the buffer strip.

[0024] The following is combined with the attachedFigure 1 - Attachment Figure 3 This application will be further described in detail below.
[0025] An embodiment of this application provides a photovoltaic panel with an adjustable tilt angle, which includes a photovoltaic panel body 10 and a mounting frame 20 for mounting the photovoltaic panel body 10. The mounting frame 20 is fixed on a mounting foundation at a specified position.
[0026] The photovoltaic panel body 10 includes a photoelectric conversion board 11 and a backplane 12 mounted on the back of the photoelectric conversion board 11. The backplane 12 is used to reinforce the photoelectric conversion board 11.
[0027] The mounting frame 20 includes a fixed frame 21 for fixedly connecting with the mounting foundation. A connecting frame 22 and a connecting rod 23 are mounted on the fixed frame 21. One end of the connecting rod 23 far from the fixed frame 21 is provided with a limiting component 30 for limiting the angle of the photovoltaic panel body 10. A shape-variable elastic body 31 is arranged in the limiting component 30.
[0028] The photoelectric conversion board 11 is mounted on the connecting frame 22 through the backplane 12. The angle between the photovoltaic panel body 10 and the connecting frame 22 is adjustable. The bottom of the backplane 12 has an extension section 14, and the extension section 14 extends into the limiting component 30.
[0029] When the photovoltaic panel body 10 is subjected to wind load, the change in the angle between the photovoltaic panel body 10 and the mounting frame 20 forces the shape of the elastic body 31 to change. When the wind load disappears, the elastic body 31 returns to its original shape, and the angle between the photovoltaic panel body 10 and the mounting frame 20 is reset.
[0030] The following is a further introduction in combination with specific usage scenarios.
[0031] During use, the operator installs the fixed frame 21 of the mounting frame 20 on the foundation at a specified location to ensure the stable position and orientation of the device body.
[0032] The angle between the photovoltaic panel body 10 and the connecting frame 22 is adjustable. When the photovoltaic panel is subjected to wind load, the extension section 14 at the bottom of the backplane 12 moves within the limiting component 30, causing the elastic body 31 to be forced to deform. At this time, the angle between the photovoltaic panel body 10 and the connecting frame 22 changes. Taking the ground as a reference, the angle between the photovoltaic panel body 10 and the ground decreases, and relative to the ground, the erection angle of the photovoltaic panel body 10 becomes gentler. In this way, the wind load applied to the photovoltaic panel by the wind decreases, reducing the probability of damage to the photovoltaic panel.
[0033] When the wind generates and applies an instantaneous wind load to the photovoltaic panel, the photovoltaic panel can relieve the instantaneous wind load by changing its angle relative to the connecting frame 22, and can avoid the probability of the photovoltaic panel body 10 being bent and damaged due to excessive instantaneous wind load.
[0034] It can be found that in the embodiment of the present application, by adopting the limiting component 30 and the method of adjustable angle of the photovoltaic panel body 10, the photovoltaic panel body 10 can avoid and relieve the instantaneous wind load by changing its own angle relative to the ground, and at the same time can reduce the subsequent wind load, without the need for additional reinforcement of the photovoltaic panel body 10, reducing the construction cost, lowering the requirements for the installation foundation, and at the same time reducing the probability of damage to the photovoltaic panel body 10.
[0035] In the embodiment of the present application, the photovoltaic panel body 10 can rotate relative to the connecting frame 22. In some possible implementation manners of the embodiment of the present application, a rotating connecting member 13 is provided on the side of the back plate 12 away from the photovoltaic conversion plate 11, and the rotating connecting member 13 is rotatably connected to the connecting frame 22. The photovoltaic panel body 10 realizes the adjustable angle between the photovoltaic panel body 10 and the mounting frame 20 through the rotational connection between the rotating connecting member 13 and the connecting frame 22;
[0036] The limiting component 30 is used to limit the shape and position of the photovoltaic panel body 10, so that it only reduces the included angle with the ground bracket under the action of wind load to relieve and reduce the wind load. In some possible implementation manners of the embodiment of the present application, the limiting component 30 includes two limiting frames 32, both of the two limiting frames 32 are installed on the connecting rod 23, a semi-open limiting area 33 is formed between the two limiting frames 32, and the elastic body 31 is located in the limiting area 33. The elastic body 31 is fixedly connected to one of the limiting frames 32. In the case of no wind load, the elastic body 31 presses against the extension section 14 to make the extension section 14 closely adhere to one of the limiting frames 32 away from the elastic body 31. In the case of having wind load, with the rotation connection point between the photovoltaic panel body 10 and the connecting frame 22 as the center of the circle, the extension on the back plate 12 moves between the two limiting frames 32, squeezing the elastic body 31 to cause the elastic body 31 to undergo elastic deformation. After the wind load disappears, the elastic body 31 restores the deformation to reset the photovoltaic panel body 10. The elastic body 31 can be selected as a simple and reliable elastic sheet, or a buffer strip 34 can be installed on the limiting frame 32 away from the limiting frame 32 where the elastic body 31 is installed. In the case of no wind load, the extension section 14 closely adheres to the buffer strip 34, and when resetting, the buffer strip 34 can effectively buffer the photovoltaic panel body 10.
[0037] In some possible implementation manners of the embodiments of the present application, the installation position of the connecting rod 23 on the fixed frame 21 is adjustable. An operator can control the positional relationship between the limiting component 30 at the end of the connecting rod 23 and the photovoltaic panel body 10 by adjusting the installation position of the connecting rod 23 on the fixed frame 21, so as to achieve the purpose of controlling the pitching angle of the installation of the photovoltaic panel body 10. In a specific implementation, a plurality of through holes 24 are formed in both the fixed frame 21 and the connecting rod 23. The connecting rod 23 is detachably connected to the fixed frame 21 by bolts passing through the through holes 24 in the fixed frame and the connecting rod 23, and the connection position of the connecting rod 23 on the fixed frame 21 is determined by controlling the overlapping position of the through holes 24 on the fixed frame 21 and the connecting rod 23.
[0038] The embodiments of the present specific implementation manners are all preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
