[0022] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will provide a detailed description of the specific embodiments of the present invention with reference to the drawings in the specification.

[0023] Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar generalizations without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0024] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other from other embodiments.

[0025] Embodiment 1

[0026] Refer toFigures 1 to 3 , which is the first embodiment of the present invention. This embodiment provides a wind disturbance flow control device for a photovoltaic panel, including

[0027] a photovoltaic component 1; a flow disturbance part 2 is provided on its windward surface;

[0028] The flow disturbance part 2 has a windward stress surface 21. When the air flow of the wind contacts the stress surface 21, the air flow is separated into air flows in multiple directions;

[0029] In this embodiment, the flow disturbance part 2 has a relatively thin sheet-like structure, the stress surface 21 has a large area, and the flow disturbance part 2 is arranged non-parallel to the ground. When a strong wind comes, the stress surface 21 of the flow disturbance part 2 directly contacts the air flow of the wind and is diverted into multiple directions. By decomposing the strong air flow in the main wind direction into weak air flows in multiple directions, the effect of disturbing the flow is achieved, reducing the stress impact brought by the strong wind to the photovoltaic module, avoiding the detachment of the photovoltaic module, and reducing economic losses.

[0030] Specifically, at least one group of flow disturbance parts 2 is arranged on the back surface of the photovoltaic component 1;

[0031] The photovoltaic component 1 includes a photovoltaic frame 11. A photovoltaic panel is provided in the photovoltaic frame 11. The photovoltaic frame 11 is inclined and arranged on a photovoltaic support 12. The end of the flow disturbance part 2 is installed on the top cross beam of the photovoltaic support 12 and is located on the back surface of the photovoltaic frame 11;

[0032] Preferably, in specific implementation, multiple groups of flow disturbance parts 2 can be arranged along the cross beam of the photovoltaic support 12 to improve the flow disturbance effect.

[0033] Specifically, the length of the flow disturbance part 2 is greater than the height of the photovoltaic component 1;

[0034] By completely covering the back surface of the photovoltaic panel with the flow disturbance part 2, the air flow of the wind can fully contact the flow disturbance part 2, avoiding the direct action of strong wind on the photovoltaic panel and further protecting the photovoltaic panel.

[0035] Specifically, the flow disturbance part 2 is made of a deformable flexible material;

[0036] Since the flow disturbance part 2 is made of a flexible material, when a strong wind comes, the stress surface 21 of the flow disturbance part 2 is affected by the wind direction and forms an arc surface. The arc surface separates the air flow in contact with it into air flows in multiple directions, thus achieving the effect of disturbing the flow.

[0037] In this embodiment, the flow disturbance part 2 is preferably composed of PVC material, which belongs to a plastic material and can cut the size and size of the flow disturbance soft board at any time according to the actual situation on site.

[0038] Specifically, a suspension rod 22 is provided at the bottom end of the flow disturbance part 2;

[0039] The bottom end of the spoiler part 2 is fixedly provided with a hanging rod 22, and the hanging rod 22 makes the bottom end of the spoiler part 2 have a moving weight, so that it is not easily turned upwards by the influence of wind, thereby ensuring the spoiler effect of the spoiler part 2 on the wind.

[0040] In summary, by arranging the spoiler part 2 on the back of the photovoltaic panel, the flow direction of the wind is disturbed and divided into weak airflows in multiple directions, thereby reducing the influence of the wind on the photovoltaic structure, greatly reducing the failure rate of the centralized photovoltaic power station in strong wind weather, and the situation of zero-current string and component shedding.

[0041] Embodiment 2

[0042] Referring to Figures 1 to 3 , this is the second embodiment of the present invention. Different from the previous embodiment, an installation mechanism 4 is provided on the photovoltaic component 1, and the end of the spoiler part 2 is fixed to the photovoltaic component 1 through the installation mechanism 4;

[0043] The installation mechanism 4 includes a fixing frame 41 fixedly arranged on the cross beam of the photovoltaic bracket 12. A reel 42 is rotatably arranged on the fixing frame 41, and one end of the spoiler part 2 is fixed to the reel 42, so that the spoiler part 2 can be fixedly installed on the photovoltaic mechanism.

[0044] Specifically, the spoiler part 2 can be wound around the installation mechanism 4;

[0045] A motor 43 is installed on the fixing frame 41, and the output section of the motor 43 is connected to the end of the reel 42. Since the spoiler part 2 is made of a flexible material and the end of the spoiler part 2 is fixedly connected to the reel 42, when the motor 43 drives the reel 42 to rotate, the spoiler part 2 can be wound around the outside of the reel 42 to store the spoiler part 2 or to adjust the release length of the spoiler part 2.

[0046] The rest of the structure is the same as that of Embodiment 1.

[0047] By storing or adjusting the spoiler part 2 through the installation mechanism 4, the spoiler part 2 can be flexibly applied according to the on-site situation.

[0048] Embodiment 3

[0049] Referring to Figures 1 to 3 , this is the third embodiment of the present invention. Different from the previous embodiment, a flow deflector 3 is further provided on the side of the photovoltaic component 1;

[0050] Among the photovoltaic components 1 arranged in the same row, a flow deflector 3 is fixedly arranged on the photovoltaic frame 11 at the end. The flow deflector 3 can affect the flow direction of the oncoming wind on the side of the photovoltaic panel, thereby achieving the effect of further protecting the photovoltaic panel.

[0051] Specifically, the windward surface of the flow deflector 3 is provided with an arc surface 31; when the wind passes through the surface of the flow deflector 3, the wind is cut into a flow direction parallel to the photovoltaic frame 11;

[0052] The surface of the flow deflector 3 is provided with symmetric arc-shaped surfaces 31 on the left and right. The edges where the two groups of arc-shaped surfaces 31 are connected correspond to the oncoming wind direction. When the wind comes from the corresponding wind direction, the arc-shaped surfaces 31 will cut it into two wind directions parallel to the tangent of its surface, thereby reducing the force on the side of the photovoltaic frame 11 and further protecting the photovoltaic panel.

[0053] The flow deflector 3 is further provided with a flat surface 32, and it is installed on one side of the photovoltaic frame 11 through the flat surface 32.
