Description
Technical Field
[0001] The utility model relates to the field of photovoltaics, and in particular to a photovoltaic component capable of reducing wind resistance. Background Art
[0002] Photovoltaic modules are devices that use solar energy to convert light energy into electrical energy. When in use, they generally need to be placed in outdoor areas with sufficient sunlight. These areas are relatively open and often encounter strong winds. Existing photovoltaic modules are all installed on a fixed frame. Due to the large surface area of photovoltaic modules, strong winds will form greater resistance on their surface. The pressure caused by strong winds can easily shorten the life of photovoltaic modules, and there is also a risk of them being overturned in extremely bad weather.
[0003] The patent with application number 202221711195.7 discloses a solar photovoltaic module with a hollow illumination surface. It divides the entire photovoltaic panel into multiple rectangular frames, and uses the flipping of multiple rectangular frames to form gaps between adjacent rectangular frames, so that air can pass through the gaps, thereby achieving the purpose of reducing wind resistance; however, this structure completely subverts the traditional photovoltaic panel structure. When collecting electricity, each rectangular frame needs to be equipped with a separate circuit, the structure becomes very complicated, and the existing production equipment cannot be used for production, and a new production line needs to be redeveloped, which greatly increases the manufacturing cost.
[0004] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the invention
[0005] The purpose of the utility model is to address the deficiencies of the prior art, thereby providing a photovoltaic assembly with scientific design, no need to modify the existing photovoltaic panel structure, the ability to automatically unload wind force, simple structure and the ability to reduce wind resistance.
[0006] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a photovoltaic component that can reduce wind resistance, including a photovoltaic panel body and an arched back panel, the top of the arched back panel is connected to the top of the back side of the photovoltaic panel body, the bottom of the arched back panel is connected to the bottom of the back side of the photovoltaic panel body, the middle part of the arched back panel is arched backward in an arc shape, and hinged columns are coaxially arranged on both sides of the middle part of the arched back panel.
[0007] Based on the above, a ventilation cavity is formed between the photovoltaic panel body and the arched back plate, and both sides of the ventilation cavity are open.
[0008] Based on the above, a counterweight block is fixedly arranged at the bottom of the ventilation cavity.
[0009] Based on the above, it also includes two buffer strips, the upper parts of the two buffer strips are pasted on the middle and lower parts of both sides of the back of the arched back plate, and the bottom of the buffer strips is pasted on the back of the bottom frame of the photovoltaic panel body.
[0010] The utility model has substantial characteristics and progress compared with the prior art. Specifically, the utility model can guide the wind direction on the back and reduce the wind resistance on the back of the photovoltaic panel body by setting the arched back plate. On the other hand, a matching mounting frame can be set, which is hingedly mounted on the mounting frame through the hinged column. In this way, when wind comes from the front, if the wind overcomes the gravity of the photovoltaic component itself, it will drive the photovoltaic component to rotate and reduce the angle with the incoming wind, thereby achieving the effect of relieving wind pressure. After the wind force decreases, the photovoltaic component can automatically return to its original position driven by its own gravity. It has the advantages of scientific design, no need to change the existing photovoltaic panel structure, automatic wind relief, and simple structure.
[0011] Furthermore, by providing the ventilation cavity, side wind can pass through it, thereby reducing side wind resistance; by providing the counterweight block, the center of gravity of the photovoltaic component can be lowered and stability can be improved; the buffer belt can be provided so that when the photovoltaic component returns to its original position, it can elastically contact with the matching mounting frame, thereby reducing impact force and preventing it from being easily bumped and damaged.

[0015] The technical solution of the utility model is further described in detail below through specific implementation methods.
[0016] like Figure 1 and Figure 2 As shown, a photovoltaic component capable of reducing wind resistance comprises a photovoltaic panel body 1 and an arched back plate 2, wherein the top end of the arched back plate 2 is connected to the top of the back side of the photovoltaic panel body 1, the bottom end of the arched back plate 2 is connected to the bottom of the back side of the photovoltaic panel body 1, the middle portion of the arched back plate 2 is arched backward in an arc shape, and hinged columns 3 are coaxially arranged on both sides of the middle portion of the arched back plate 2; a ventilation cavity 4 is formed between the photovoltaic panel body 1 and the arched back plate 2, and both sides of the ventilation cavity 4 are open.
[0017] During specific use, it is necessary to set up a mounting frame that matches the photovoltaic component that can reduce wind resistance, and hinge the hinged columns 3 on both sides to install them on the mounting frame. In the natural state, the mounting frame supports the middle and lower part of the arched backboard 2. The arched backboard 2 can use its own curvature to guide the wind direction on the back and reduce the wind resistance on the back. The side wind can pass through the ventilation cavity 4 to reduce the side wind resistance. When the front wind blows, if the wind force overcomes the gravity of the photovoltaic component itself, it will drive the photovoltaic component to rotate and reduce the angle with the wind, thereby achieving the effect of relieving wind pressure. After the wind force decreases, the photovoltaic component can automatically return to its original position driven by its own gravity.
[0018] In order to improve its stability, a counterweight block 5 is fixedly arranged at the bottom of the ventilation cavity 4, which can lower the center of gravity of the photovoltaic module and thus improve stability.
[0019] In order to reduce the impact on the photovoltaic component when it returns to its original position, the photovoltaic component that can reduce wind resistance also includes two buffer belts 6, the upper parts of the two buffer belts 6 are adhered to the middle and lower parts of both sides of the back side of the arched back plate 2, and the bottom of the buffer belt 6 is adhered to the back side of the bottom frame of the photovoltaic panel body 1; when the photovoltaic component returns to its original position, the buffer belt 6 will elastically contact with the matching mounting frame to reduce the impact force and is not easy to be bumped and damaged.
[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
