Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic module technology, and in particular to a frame structure for an anti-dust-accumulation photovoltaic module. Background Technology
[0002] The existing photovoltaic module frame is 3-5mm higher than the front glass of the photovoltaic module. When the photovoltaic module is in use, dust or water will accumulate under the photovoltaic panel. It cannot fall off or be cleaned automatically. Over time, this accumulation will lead to damage to power generation and reduced power generation efficiency.
[0003] Currently, some manufacturers use a dust-prevention solution: aligning the top surface of the short side frame of the photovoltaic module with the light-receiving surface of the photovoltaic panel, which allows for the automatic removal of dust and water from the panel. However, this reduces the photovoltaic module's ability to withstand back pressure.
[0004] Some manufacturers use a different method to prevent dust accumulation: cutting several slots on the front of the photovoltaic module frame to allow rainwater to flow out and carry away dust. However, this method makes it difficult to process the slots in the photovoltaic module frame profile, and there will be excess adhesive at the slots when installing the photovoltaic module frame. Utility Model Content
[0005] The technical problem to be solved by this utility model is: in view of the problems in the prior art, such as the easy accumulation of dust in photovoltaic modules affecting power generation, the difficulty in processing the frame structure of anti-dust photovoltaic modules, the impact on the load performance of the back of the module, and the overflow of glue on the front of the slotted frame profile, a frame structure for anti-dust photovoltaic modules is provided.
[0006] The technical solution adopted by this utility model to solve its technical problem is: a frame structure for a dust-proof photovoltaic module, including a first frame, a second frame and corner brackets. The first frame and the second frame are connected at the corners by corner brackets to form a rectangular frame structure. A third frame is added at the corners of the first frame and / or the second frame. The third frame includes a side structure and a bottom structure. The side structure and the bottom structure form an L-shaped frame embedding opening for embedding the side of the photovoltaic module body.
[0007] The side structure is located on the side of the component body, and the bottom structure is located on the back surface of the component body. The side structure is flush with the light-receiving surface of the component body, so that the front of the third frame is flush with the light-receiving surface of the component body; or, the side structure is lower than the side of the component body, so that the front of the third frame is lower than the light-receiving surface of the component body.
[0008] The side arm of the corner piece passes through the third border and then inserts into the first and second borders, connecting the first, second, and third borders together.
[0009] Furthermore, a third border segment is added to both corners of the first border; or, a third border segment is added to both corners of the second border; or, a third border segment is added to both corners of the first border and the second border.
[0010] Furthermore, the lower structure has a corner code slot for inserting the side arm of the corner code.
[0011] Furthermore, the first and second borders, like the third border, both have side structures and bottom structures. The first and second borders also include an upper structure, with the upper and lower structures respectively located on the upper and lower sides of the side structure. The upper, side, and lower structures form a border inlet for inserting the side of the photovoltaic module body.
[0012] Furthermore, the L-shaped border of the third border has an overflow groove, and the overflow space of the overflow groove of the third border is greater than that of the overflow groove of the first border and the second border.
[0013] Furthermore, the frame structure of the anti-dust photovoltaic module is made of aluminum alloy, and the corner brackets are L-shaped corner brackets with serrations.
[0014] Furthermore, the length of the third frame is 20mm-50mm, the length of the side arm of the corner piece is 50mm-90mm, and the length of the third frame is less than the length of the side arm of the corner piece.
[0015] The beneficial effects of this utility model are as follows: The frame structure of the anti-dust photovoltaic module of this utility model, by adding a small section of the third frame when the first frame, the second frame and the corner bracket are connected, forms a groove for rainwater to flow out, preventing water and dust accumulation in the photovoltaic module; the groove is formed by the side structure of the third frame that is flush with the light-receiving surface of the photovoltaic module body, the processing of the third frame is simple and does not affect the load-bearing efficiency of the photovoltaic module; the overflow groove formed by the third frame and the photovoltaic module is located on the side and bottom of the photovoltaic module, so the silicone after applying the glue will not overflow onto the light-receiving surface of the module body.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

[0029] Example 1
[0030] Figures 1-7The illustrated frame structure of a dust-resistant photovoltaic module includes a first frame 1, a second frame 2, and a corner bracket 4. The first frame 1 is located on the first side of the rectangular photovoltaic module body 8 in a first direction, and the second frame 2 is located on the second side of the module body 8 in a second direction. A third frame 3 is added at the corner of the second frame 2. The third frame 3 includes a side structure 5 and a bottom structure 6, which form an L-shaped frame insertion opening 53 for embedding the side of the photovoltaic module body 8. The side structure 5 is located on the side of the module body 8, and the bottom structure 6 is located on the back surface of the module body 8. The side structure 5 is flush with the light-receiving surface of the module body 8, so that the front of the third frame 3 is flush with the light-receiving surface of the module body 8. The side arm of the corner bracket 4 passes through the third frame 3 and is inserted into the first frame 1 and the second frame 2, connecting the first frame 1, the second frame 2, and the third frame 3 together to form a rectangular frame structure surrounding the module body 8.
[0031] Add a third border 3 to both corners of the second border 2.
[0032] Similar to the third frame 3, the first frame 1 and the second frame 2 both have a side structure 5 and a bottom structure 6. The first frame 1 and the second frame 2 also include an upper structure 7. The upper structure 7 is located on the light-receiving surface of the module body 8. The upper structure 7 and the bottom structure 6 are respectively set on the upper and lower sides of the side structure 5. The upper structure 7, the side structure 5 and the bottom structure 6 form a frame insertion port 51 with an opening only on the inside, which is used for the insertion of the module body 8 of the photovoltaic module into the side.
[0033] The lower structure 6 of the first border 1, the second border 2, and the third border 3 all have corner code slots 61 for inserting the side arms of the corner code 4.
[0034] An overflow groove 52 is provided in the L-shaped frame insertion opening 53 of the third frame 3. The overflow space of the overflow groove 52 of the third frame 3 is larger than that of the overflow groove 52 of the first frame 1 and the second frame 2, so as to prevent the silicone after application from overflowing onto the light-receiving surface of the component body 8. Figure 6 and Figure 7 The black parts in the frame insertion port 51 and frame embedding port 53 are the silicone that is injected into the frame insertion port 51 and frame embedding port 53, which is used to bond the frame structure to the component body 8.
[0035] The frame structure of the anti-dust photovoltaic module is made of aluminum alloy, and corner code 4 is an L-shaped corner code with serrations.
[0036] The length of the third frame 3 is 20mm-50mm, and the length of the side arm of the corner piece 4 is 50mm-90mm, with the length of the third frame 3 being less than the length of the side arm of the corner piece 4.
[0037] After the frame structure of this anti-dust photovoltaic module is assembled with the module body 8 to form a photovoltaic module, the front of the side structure 5 of the third frame 3 is flush with the front of the module body 8, forming a groove for rainwater to flow out, preventing water and dust from accumulating on the module body 8.
[0038] Of course, it is also possible that the side structure 5 of the third frame 3 is lower than the side of the component body 8, so that the front of the third frame 3 is lower than the light-receiving surface of the component body 8.
[0039] Of course, it is also possible that a third border 3 is added only to one corner of the second border 2.
[0040] exist Figure 1 In this photovoltaic module, the photovoltaic module is rectangular, with a long side and a short side. The first frame 1 is located on the long side of the photovoltaic module, and the second frame 2 and the third frame 3 are located on the short side of the photovoltaic module. The frame structure of this anti-dust photovoltaic module is suitable for the photovoltaic module to be installed vertically. When the photovoltaic module is installed horizontally, a groove needs to be left below the long side of the photovoltaic module for rainwater to flow out, that is, a section of the third frame 3 is added to both corners of the first frame 1.
[0041] Example 2
[0042] The embodiment is basically the same as that in Example 1, except that a third border 3 is added to both corners of the first border 1 and the second border 2, resulting in a total of four third border 3 segments. Specifically, as follows... Figures 8-10 As shown, the two corners of the first frame 1 have a third frame 3, and the two corners of the second frame 2 also have a third frame 3, so that grooves for rainwater to flow out are formed on both the long and short sides of the photovoltaic module. The photovoltaic module can be installed horizontally or vertically.
[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
