Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaics, and in particular to a full-screen anti-dust accumulation photovoltaic component. Background Art

[0002] Photovoltaic modules are the core components of photovoltaic power generation applications. Currently, the front and back panels of commonly used photovoltaic modules are made of tempered glass, which makes the photovoltaic modules easy to bump during transportation and carrying heavy objects. In particular, once the edges of the photovoltaic modules are damaged, it will affect the use of the photovoltaic modules. In special occasions where the pressure requirements of photovoltaic modules are high (such as carrying thick snow), the edges of photovoltaic modules are not strong enough and are easily damaged, posing a safety hazard and causing economic losses.

[0003] A photovoltaic module packaging system with patent number CN202220740579.5 is provided, in which at least one group of opposite sides of the photovoltaic module are coated with magnesium-aluminum-zinc-plated C-shaped steel, and the C-shaped steel on the long side of the photovoltaic module is clamped with a mechanically pressed short frame, thereby protecting the long side of the photovoltaic module and preventing the photovoltaic module from being damaged by excessive pressure. The system has high strength and can withstand greater pressure. However, the C-shaped steel of this structure covers the edges of the front glass and the back glass at the same time, blocking the edges of the front glass, which is not conducive to the drainage and dust removal of the front glass, reduces the utilization rate of sunlight by the photovoltaic module, and increases the material cost of the C-shaped steel. Summary of the invention

[0004] The purpose of the utility model is to overcome the above-mentioned shortcomings and provide a full-screen anti-dust photovoltaic component, which adopts zinc-magnesium-aluminum strips to be bent into a rectangular ring-shaped protective frame that matches the edge of the photovoltaic component body. The front glass of the photovoltaic component body is unobstructed, which is equivalent to a full screen, greatly improving the utilization rate of sunlight by the photovoltaic component, facilitating the drainage and dust removal of the front glass, protecting the entire edge contour of the photovoltaic component body, and greatly improving the protection of the photovoltaic component.

[0005] The purpose of the utility model is achieved in this way:

[0006] A full-screen anti-dust photovoltaic module comprises a photovoltaic module body and a protective frame. The protective frame is arranged at the edge of the photovoltaic module body. The protective frame is formed by bending a metal strip into a rectangular ring that matches the photovoltaic module body, and the seams are welded together.

[0007] Preferably, the protective frame is provided with four bending corners, and notches are provided inside the bending corners.

[0008] Preferably, the cross-section of the metal strip is L-shaped.

[0009] Preferably, the vertical side of the metal strip is in contact with the side surface of the photovoltaic module body, and the horizontal side of the metal strip is in contact with the back panel glass of the photovoltaic module body.

[0010] Preferably, the notch is provided on the horizontal side of the metal strip, and the notch is triangular before being bent, and gaps are left on both sides of the notch after being bent.

[0011] Preferably, there are two metal strips, each of which is bent into a "7" shape, and the protective frame is provided with two seams.

[0012] Preferably, there is one metal strip, and the protective frame is formed by bending only one metal strip, with one seam.

[0013] Preferably, the photovoltaic module body with the protective frame is pressed and installed with the short snap-on frame, and the seam is hidden in the short snap-on frame.

[0014] Preferably, the metal strip is made of zinc-magnesium-aluminum strip.

[0015] The beneficial effects of the utility model are:

[0016] The utility model adopts zinc-magnesium-aluminum strips to be bent into a rectangular annular protective frame that matches the edge of the photovoltaic module body. The front glass of the photovoltaic module body is unobstructed, which is equivalent to a full screen, greatly improving the utilization rate of sunlight by the photovoltaic module, facilitating the drainage and dust removal of the front glass, protecting the entire edge contour of the photovoltaic module body, and greatly improving the protection of the photovoltaic module;

[0017] The seam is hidden in the short frame of the bayonet, which is more beautiful and conducive to product promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] See also Figure 1-5 The utility model relates to a full-screen anti-dust photovoltaic module, including a photovoltaic module body 1 and a protective frame 2. The photovoltaic module body 1 and the protective frame 2 are pressed together as one piece. The protective frame 2 is arranged at the edge of the photovoltaic module body 1. An adhesive layer 3 is provided between the protective frame 2 and the photovoltaic module body 1. The adhesive layer facilitates the reliable connection between the photovoltaic module body 1 and the protective frame 2 after pressing. The protective frame 2 is formed by bending a metal strip 2.1 with an L-shaped cross-section into a rectangular ring, and the seams are welded together into one piece.

[0026] The metal strip is made of zinc-magnesium-aluminum strip.

[0027] The protective frame 2 is provided with four bending angles 2.2, and a notch 2.3 is provided inside the bending angle 2.2. The notch 2.3 has two functions. One is to facilitate the formation of a 90° bending angle; the other is to facilitate fine-tuning during the assembly process to ensure that the protective frame is compatible with the edge of the photovoltaic module.

[0028] The vertical side of the metal strip 2.1 is in contact with the side of the photovoltaic module body 1, and the horizontal side of the metal strip 2.1 is in contact with the back glass of the photovoltaic module body 1. The notch 2.3 is provided on the horizontal side of the metal strip 2.1. The notch 2.3 is triangular before being bent, and a gap of 2-3 mm is left on both sides of the notch 2.3 after being bent.

[0029] There are two metal strips 2.1, each of which is bent into a "7" shape, and the protective frame 2 is provided with two seams.

[0030] The photovoltaic module body 1 with the protective frame 2 is pressed and installed with the buckle short frame 4, and the joint is hidden in the buckle short frame 4. Except for the clamping part with the buckle frame, the front glass of the photovoltaic module body is unobstructed, which is equivalent to a full screen, greatly improving the utilization rate of sunlight by the photovoltaic module, facilitating the drainage and dust removal of the front glass, and saving 40% of the material cost compared with the C-type edge guard. The L-type edge guard can effectively prevent the photovoltaic module from being damaged by excessive pressure, so that the front of the photovoltaic module can withstand a load of up to 5400Pa and the back can withstand a load of up to 2400Pa. Example 2

[0031] See also Figure 6 The metal strip 2.1 is provided with one piece, and the protective frame 2 is formed by bending only one metal strip 2.1, and is provided with one seam, which is hidden in the short frame of the bayonet. The rest of the structure is the same as that of the first embodiment.
