Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic cells, in particular to a short-side A-side-free self-cleaning photovoltaic component frame. Background Art

[0002] The traditional photovoltaic module frame has an A-side on both the long and short sides, which will accordingly affect the lighting area of ​​the photovoltaic cells. In addition, since photovoltaic modules are used in the open air, dust is easily accumulated around the surface of the modules. Over time, this dust will seriously affect the normal use of the photovoltaic modules and reduce the photoelectric conversion rate of the photovoltaic cells.

[0003] Therefore, based on the above-mentioned problems existing in the frames of traditional photovoltaic modules, it is necessary to improve the structure to eliminate the impact of dust on the surface of the frame on the photovoltaic panels and improve the stability and conversion efficiency of the photovoltaic system. Summary of the invention

[0005] The technical solution adopted by the utility model to solve its technical problems is: a short-side A-sideless self-cleaning photovoltaic component frame, including a rectangular frame spliced ​​by two long rectangular materials and two short rectangular materials, a laminate is arranged in the rectangular frame, and an inner convex pressure plate is provided above the upper horizontal side of the long rectangular material, which is pressed against the upper edge of the laminate; a first glue overflow groove is provided between the inner end of the upper horizontal side of the short rectangular material and the upper end of the outer vertical side of the short rectangular material, and the outer vertical side of the short rectangular material extends upward and then bends inward to form a second glue overflow groove located above the first glue overflow groove, and a first baffle protruding inward is provided between the first glue overflow groove and the second glue overflow groove.

[0006] In order to improve the overall strength of the component frame, the middle of the long rectangular material has a reinforcing rib parallel to its vertical edge.

[0007] Furthermore, the reinforcing ribs are provided with threaded holes which can be fixed to the short rectangular members by means of screws.

[0008] In order to increase the load strength and the bonding area, the inner end of the upper horizontal edge of the short rectangular material has an extended edge extending inward, and the upper end surface of the upper horizontal edge is densely covered with anti-slip teeth.

[0009] Preferably, in order to facilitate the glue applied on the short rectangular material to flow into the first glue overflow groove, the outer end of the upper horizontal edge of the short rectangular material has a slope surface inclined toward the first glue overflow groove.

[0010] Furthermore, in order to facilitate the glue in the first glue overflow groove to flow into the second glue overflow groove, the two side surfaces of the first baffle are inclined surfaces.

[0011] Furthermore, the outer vertical side of the short rectangular material extends upward and is bent inwardly to be connected to a second baffle to prevent glue in the second glue overflow groove from overflowing.

[0012] The beneficial effects of the utility model are as follows: the utility model has a simple structure and is easy to install, and the A surface on the short side of the traditional component frame is eliminated. By arranging a first glue overflow groove and a second glue overflow groove that can accommodate excess glue on the short-distance profile serving as the short side of the frame, dust accumulated during use can flow out from the first glue overflow groove and the second glue overflow groove after being washed by rainwater, thereby eliminating the influence of dust on the surface of the frame on the photovoltaic panel, thereby improving the stability and conversion efficiency of the photovoltaic system.

DETAILED DESCRIPTION

[0019] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0020] like Figure 1 ,like Figure 4 A self-cleaning photovoltaic module frame with short sides and no A-surface is shown. The frame is a rectangular frame formed by splicing two long rectangular materials 1 and two short rectangular materials 2. A laminate 3 is arranged inside the rectangular frame.

[0021] like Figure 2As shown, the outer vertical side of the long rectangular material 1 is extended upward and connected to the top thereof with an inner convex pressure plate 4, which is pressed against the upper edge of the laminate 3 after the photovoltaic module is installed. A reinforcing rib 1-1 parallel to the vertical side is provided in the middle of the long rectangular material 1 to improve the overall strength of the frame, and two upper and lower threaded holes 1-2 are provided on the reinforcing rib 1-1 to be fixed to the short rectangular material 2 by screws.

[0022] like Figure 3 As shown, the inner end of the upper horizontal edge of the short rectangular material 2 has an extended edge 2-4 extending inwardly, and the upper end surface of the upper horizontal edge of the short rectangular material 2 and the extended edge 2-4 are densely covered with anti-slip teeth 2-5 to increase the frame load strength and expand the bonding area between the laminate 3 and the short rectangular material 2.

[0023] A first glue overflow groove 2-1 is provided between the inner end of the upper horizontal side of the short rectangular material 2 and the upper end of the outer vertical side of the short rectangular material 2. The outer vertical side of the short rectangular material 2 extends upward and then bends inward to form a second glue overflow groove 2-2 located above the first glue overflow groove 2-1. A first baffle 2-3 protruding inward is provided between the first glue overflow groove 2-1 and the second glue overflow groove 2-2. Both sides of the first baffle 2-3 are inclined surfaces. Meanwhile, the outer vertical side of the short rectangular material 2 extends upward and bends inward to be connected to the second baffle 2-7. The outer end of the upper horizontal side of the short rectangular material 2 has a slope surface 2-6 inclined toward the first glue overflow groove 2-1.

[0024] When glue is applied to the upper horizontal edge of the short rectangular material 2 to bond the laminate 3, excess glue will flow into the first glue overflow groove 2-1 along the slope surface 2-6. Once the amount of glue is excessive, it can flow into the second glue overflow groove 2-2 through the slopes on both sides of the first baffle 2-3. The second baffle 2-7 can prevent the glue in the second glue overflow groove 2-2 from overflowing outside the frame.

[0025] The long rectangular material 1 and the short rectangular material 2 are fixed by screws, so that the short rectangular material 2 can be installed without using a framing machine. Because the traditional angle code connection method has a large framing force of the framing machine, it is easy to produce more glue overflow for the short rectangular material 2 without a clamping surface. The use of screws to fix can effectively reduce the glue overflow problem while ensuring a reliable connection, ensuring that the laminate 3 is firmly bonded.

[0026] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
