Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaics, in particular to a photovoltaic component frame and a photovoltaic component. Background Art

[0002] Photovoltaic modules are the core part of photovoltaic power generation systems and are usually installed in open areas with plenty of sunshine. During long-term outdoor use, a lot of dust will inevitably adhere to the edges of photovoltaic modules, which may affect the appearance of photovoltaic modules at the least and the power generation of photovoltaic modules at the worst. In addition, due to the existence of obstructions, the current and voltage of some cells in the photovoltaic modules will change, causing hot spots and leading to safety hazards such as local overheating of photovoltaic modules.

[0003] In the related art, the anti-dust design of photovoltaic modules is generally to add a cell-free area on the short side of the module or to make grooves on the frame of the short side of the module. Although the above methods can avoid a large amount of dust from adhering to the photovoltaic modules to a certain extent, there are still many problems. For example, the anti-dust module of patent CN205039162U has a blank area for dust accumulation on the lower side of the short side of the module. Although it can prevent the hot spot effect caused by the cell being blocked by dust, the dust still adheres to the short side of the module because the frame is higher than the front glass of the module, and the module cannot achieve the anti-dust ability. Moreover, the blank area on the lower side of the module cannot generate electricity, resulting in an increase in the cost per kilowatt-hour of the photovoltaic system. Another example is an anti-dust photovoltaic module of patent CN217935550U, which has an anti-dust area between the lower edge of the photovoltaic body and the lower edge of the frame close to the ground, and a number of drainage holes are opened on the frame floor of the anti-dust area. The drainage holes may have a certain drainage effect in the early stage, but because the module works outdoors for a long time, a large amount of dust may block the drainage port, resulting in the loss of anti-dust ability.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the utility model.

[0026] The following is combined with Figure 1 To Attachment Figure 3 And specific embodiments describe the present invention in detail.

[0027] like Figure 1-3 As shown, the embodiment of the present application provides a photovoltaic module frame for installing a laminate 6, including a support portion. The present application takes the support portion as a rectangular tubular support portion as an example for explanation, but is not limited thereto. A support seat 11 is formed on the top of the rectangular tubular support portion 1. The support seat 11 is used to bond with the bottom surface of the laminate 6 to provide support force for the laminate 6. An upwardly extending side plate 2 is fixed to one end of the support seat 11. A baffle 3 is fixed near the top of the side plate 2. The distance between the top surface of the baffle 3 and the support seat 11 is less than or equal to the thickness of the laminate 6. In other words, Figure 3 As shown, when the laminate 6 is installed, the baffle 3 only contacts the side of the laminate 6, and the baffle 3 in contact with the laminate 6 is rounded to reduce the risk of the laminate bursting when the laminate is framed.

[0028] Specifically, in this embodiment, the other end of the support seat is fixed with an internal support plate 13 extending downward, and a glue-bearing member 5 is fixed on the side of the internal support plate 13 away from the side plate 2. The glue-bearing member 5 and the internal support plate 13 form a glue-bearing groove 51, and the glue-bearing groove 51 is open and upwardly arranged. The shape of the glue-bearing groove 51 includes but is not limited to: U-shaped structure, V-shaped structure, W-shaped structure, and can achieve the function of glue storage. The silica gel overflowing from the area where the laminate 6 and the frame are attached is collected in the glue-bearing groove 51, so as to achieve the technical effect of no glue overflow on the back of the component.

[0029] Specifically, one end of the support seat 11 is also formed with an external support plate 12 extending downward, the external support plate 12 and the internal support plate 13 are arranged in parallel, the support seat 11 is connected to the upper ends of the external support plate 12 and the internal support plate 13, the external support plate 12 and the side plate 2 are located on the same vertical plane, the lower ends of the external support plate 12 and the internal support plate 13 are connected to the frame base 14, and the support seat 11, the external support plate 12, the internal support plate 13 and the frame base 14 together form a rectangular tubular support portion 1. Preferably, the thickness of the external support plate 12, the internal support plate 13, the support seat 11 and the frame base 14 are all 1.0-2.0 mm, and within this thickness range, the strength and stability of the frame structure can be guaranteed.

[0030] Specifically, in this embodiment, the baffle 3 is integrally formed with the side plate 2, the baffle 3 is horizontally arranged on the top of the side plate 2, the width of the baffle 3 is 1.2-1.8 mm, and the distance between the top surface of the baffle 3 and the support seat 11 is equal to the thickness of the laminate. Figure 2 As shown, the integrally formed baffle plate 3 and the side plate 2 are in an inverted L-shaped structure, and the horizontal width of the inverted L-shaped structure is 1.2-1.8 mm, and the vertical height is 4.4-4.8 mm. The vertical height of the inverted L-shaped structure is the same as the thickness of the laminate 6. Those skilled in the art can know that the width of the structure on a conventional frame is generally 11.0-11.5 mm. Therefore, it can be seen that the 1.2-1.8 mm width design of the present application greatly reduces the material cost of the frame. At the same time, since the baffle plate 3 no longer covers the upper surface of the laminate 6, the power generation loss of the photovoltaic module can be reduced and the power generation efficiency can be improved.

[0031] It is worth noting that the baffles of the frames of conventional photovoltaic modules are usually higher than the laminates and in contact with the upper surface of the laminates, shielding the edges of the laminates. Such a design causes a large amount of dust to adhere to the edges of the laminates during long-term outdoor use of the photovoltaic modules and cannot be eliminated by itself, resulting in the hot spot phenomenon. However, the top surface of the baffle 3 of the present application is flush with the laminate 6, eliminating the space for dust accumulation, so that the dust cannot exist stably on the photovoltaic module, and can be eliminated by itself under the scouring effect of strong winds or rain.

[0032] Specifically, the ratio of the height of the baffle 3 in the vertical direction to the height of the side plate 2 in the vertical direction is 1 / 3-1 / 2. For example, if the height of the baffle 3 is 1.1 mm, then the height of the side plate 2 is 2.2-3.3 mm. Within this numerical range, the capacity of the glue storage tank 4 is within a suitable range, so that glue overflow is not likely to occur during the installation of the laminate 6.

[0033] Preferably, the inner side surface of the side panel 2 is a smooth vertical surface, which is equivalent to the bottom surface of the glue storage tank 4. On the one hand, it provides the possibility of increasing the glue storage space of the glue storage tank 4 and reducing the risk of glue overflow. On the other hand, since it is a vertical smooth surface, it has a certain distance from the side surface of the laminate when framing, so that the inner side surface of the side panel has no possibility of contacting the laminate, thereby reducing the risk of panel explosion. In particular, the inner side surface of the side panel 2 refers to the side opposite to the side surface of the laminate, that is, the side facing the laminate.

[0034] Specifically, Figure 3 As shown, the support surface of the support seat 11 is arranged horizontally, so that the laminate 6 can be fitted with the support surface over a large area, so that the laminate 6 can be stably supported on the support seat 11. At the same time, the support surface is a smooth surface without sharp protrusions, which is not easy to damage the laminate during framing, and can reduce the risk of panel explosion.

[0035] Specifically, the baffle plate 3, the side plate 2 and the support seat 11 form a glue storage tank 4, which is a U-shaped tank with an opening toward the side of the laminate 6. The interior of the U-shaped tank is smooth, which is easy to store more silica gel and reduce the risk of glue overflow.

[0036] Specifically, the height of the glue receiving groove 51 is 4.0-4.5 mm, and the ratio of the height of the glue receiving groove 51 to the height of the internal support plate 13 is 1 / 4-1 / 5. Within this value range, the space of the glue receiving groove 51 is sufficient to collect overflowed silicone, ensuring that there is no glue overflow on the back of the component.

[0037] Specifically, the top of the adhesive support 5 extends away from the inner support plate 13 to form a horizontal support portion 52, and the top surface of the horizontal support portion 52 is flush with the support surface of the support seat 11. The horizontal support portion 52 can better support the laminate 6 and improve the stability of the laminate 6.

[0038] The embodiment of the utility model also provides a photovoltaic module, including a laminate and any one of the above photovoltaic module frames, and the photovoltaic module frame is a short frame arranged at the edge of the laminate, ensuring that dust on the surface of the module can be washed by rainwater and flow out through the baffle of the short frame, ensuring that dust does not accumulate on the module. The long side of the laminate can be matched with the long frame in the prior art, and the upper surface of the long side edge of the laminate is located in the baffle at the top of the long frame in the prior art. The upper surface of the laminate is limited by the baffle to ensure that the photovoltaic module has the ability to resist loads.

[0039] The photovoltaic module of the present application adopts all the technical solutions of all the above-mentioned frame embodiments, and therefore, at least has all the beneficial effects brought by the technical solutions of the frame embodiments, which will not be repeated here.

[0040] The utility model is further described above with the help of specific embodiments, but it should be understood that the specific description here should not be construed as limiting the essence and scope of the utility model. Various modifications made to the above embodiments by ordinary technicians in this field after reading this specification are all within the scope of protection of the utility model.
