Description

Technical Field

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

[0002] Photovoltaic modules are part of the solar power generation system. Single solar cells cannot be used directly as a power source. When used as a power source, several single cells must be connected in series and parallel and tightly sealed into modules. Solar cell modules are the core part of the solar power generation system and the most important part of the solar power generation system. Since photovoltaic panels cannot be used alone, multiple groups of photovoltaic panels need to be combined to absorb sunlight. Most existing photovoltaic panels are designed with A-side frames when in use. There are also photovoltaic module designs without A-side frames. The surface of photovoltaic modules without A-side frames is not easy to accumulate dust. They can be used in distributed and large power stations. The product is beautiful and can reduce power generation losses caused by dust accumulation.

[0003] However, the existing full-screen photovoltaic modules also have some problems due to the design without A-side frame. For example, the Chinese patent document with announcement number CN208820731U discloses an edge-hook double-sided double-glass photovoltaic module, which includes multiple corner guards, which are arranged at the corners of the mounting part. The corner guards can protect the corners of the photovoltaic panel when they are hit at the corners. The corner guards have a good protective effect on the mounting part, but the corner guards are tightly combined with the mounting part. Photovoltaic modules are generally dusty when used outdoors for a long time. The dust will flow to the position of the corner guards below with rainwater on rainy days, but the combination of the corner guards and the mounting part will affect the flow of rainwater, which is not conducive to cleaning the dust. Utility Model Content

[0008] Furthermore, the corner guard includes an adjacent first covering surface, a second covering surface, and an oppositely arranged third covering surface and a fourth covering surface, and the first covering surface, the second covering surface, the third covering surface and the fourth covering surface constitute a covering structure covering the corner of the photovoltaic panel.

[0009] Furthermore, the third covering surface is arranged in parallel with the front surface of the photovoltaic panel, the fourth covering surface is arranged in parallel with the back surface of the photovoltaic panel, and a gap is left between the third covering surface and the frame.

On the one hand, it can increase the impact resistance of the corner of the photovoltaic panel and reduce the risk of damage to the photovoltaic panel due to impact. On the other hand, the corner guard can cover the gap between adjacent frames. A gap is left between the covering surface of the corner guard and the frame, providing a path for the accumulated water to drain away, making it easier for the water to flush away the dust. In addition, the gap between the covering surface of the corner guard and the frame reserves space for the installation of the photovoltaic panel, increasing the convenience of installing the photovoltaic panel.

[0020] (2) In the utility model, a full-screen photovoltaic module, the first covering surface, the second covering surface, the third covering surface and the fourth covering surface of the corner guard can provide all-round protection for the corners of the photovoltaic panel from top to bottom and from left to right.

[0030] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the drawings and embodiments. What is described here is only the preferred embodiment of the utility model. Those skilled in the art can think of other ways to implement the utility model based on the preferred embodiment, and other ways also fall within the scope of the utility model.

[0031] Example

[0032] Reference Figure 1-Figure 5 , this embodiment provides a full-screen photovoltaic module, including a photovoltaic panel 1, a frame 2 and a corner guard 3, four frames 2 surround the outside of the photovoltaic panel 1, two adjacent frames 2 are connected at the corners of the photovoltaic panel 1, and the corner guard 3 covers the connection between the two adjacent frames 2. On the one hand, the corner guard 3 can increase the impact resistance of the corner of the photovoltaic panel 1 and reduce the risk of damage to the photovoltaic panel 1 due to impact. On the other hand, the corner guard 3 can cover the connection seam where adjacent frames 2 are connected, thereby improving the sealing and aesthetics of the connection between the frames 2. A gap is left between one of the covering surfaces of the corner guard 3 and the frame 2, and the gap provides a path for the accumulated water to be discharged, so as to facilitate the water to wash away the dust. Moreover, the gap between the covering surface of the corner guard 3 and the frame 2 reserves space for the installation of the photovoltaic panel 1, thereby increasing the convenience of installing the photovoltaic panel 1.

[0033] It should be noted that the photovoltaic panel 1 in this embodiment is a quadrilateral structure, so the number of the frame 2 is four. When the structure of the photovoltaic panel 1 is a triangle, a pentagon or other polygon, the number of the frame 2 is correspondingly set to three, five or more. In addition, in order to enhance the coverage of the frame 2 by the corner protector 3, this embodiment only leaves a gap between one of the covering surfaces of the corner protector 3 and the frame 2. If the drainage capacity of the corner protector 3 is to be increased, it is also possible to consider leaving a gap between two or even three covering surfaces of the corner protector 3 and the frame 2.

[0034] Specifically, Figure 3 As shown, the corner guard 3 includes an adjacent first covering surface 301, a second covering surface 302, and a third covering surface 303 and a fourth covering surface 304 which are arranged opposite to each other. The first covering surface 301, the second covering surface 302, the third covering surface 303 and the fourth covering surface 304 constitute a covering structure covering the corner of the photovoltaic panel 1. The third covering surface 303 is arranged parallel to the front side of the photovoltaic panel 1, and the fourth covering surface 304 is arranged parallel to the back side of the photovoltaic panel 1. Therefore, the corner guard 3 can cover the top, bottom, left and right sides of the corner of the photovoltaic panel 1, further improving the anti-collision ability of the corner of the photovoltaic panel 1. Among them, there is a gap between the third covering surface 303 and the frame 2. The gap is formed by controlling the distance between the third covering surface 303 and the fourth covering surface 304 to be greater than the height of the frame 2. Retaining the gap can facilitate rainwater to flow out after washing away dust.

[0035] It should be noted that the so-called front side of the photovoltaic panel 1 refers to the side of the photovoltaic panel 1 facing the sun, and the so-called back side of the photovoltaic panel 1 refers to the side opposite to the front side of the photovoltaic panel 1, that is, the side facing away from the sun.

[0036] The corner guard 3 provides good protection and drainage functions for the corners of the photovoltaic panel 1. It is also necessary to consider the stability of the installation of the corner guard 3 and the fit between the corner guard 3 and the frame 2. A limit device is set between the corner guard 3 and the frame 2 to limit the position of the corner guard 3 and the frame 2 to meet the stability requirements and fit requirements. Figure 2 , Figure 4 and Figure 5 As shown, the fourth covering surface 304 is provided with a limiting protrusion 305, and the two adjacent frames 2 are respectively provided with a limiting hole 201, and the limiting protrusion 305 is correspondingly engaged with the limiting hole 201 to form a limiting device for the corner protector 3 and the frame 2.

[0037] Two adjacent frames 2 at the corners of the photovoltaic panel 1 need to be connected by a connector to form an enclosing frame structure. There are many options for the connector. In this embodiment, Figure 4 and Figure 5 As shown, the photovoltaic assembly also includes a corner bracket 4 as a connector, which is arranged on the inner side of the corner guard 3 and connects two adjacent frames 2 at the corner of the photovoltaic panel 1. In order to improve the stability of the installation of the corner guard 3 and the corner bracket 4, the corner of the corner bracket 4 is connected to the inner side of the corner guard 3 through a snap-fit ​​structure.

[0038] Specifically, Figure 3 and Figure 5 As shown, the clamping structure includes two clamps 306 arranged in parallel, and there is a gap 307 between the two clamps 306; two buckle grooves corresponding to the clamps 306 are arranged at the corners of the corner bracket 4, and the two buckle grooves are blocked by the convex rib 401. When the clamp 306 is engaged with the buckle groove, the convex rib 401 extends into the gap 307. The combination of the convex rib 401 and the gap 307 can further enhance the anti-torsion ability of the clamping structure, and can ensure that the corner protector 3 and the corner bracket 4 cannot fall off within the standard torque after being clamped, and further improve the stability of the combination of the corner protector 3 and the corner bracket 4. Furthermore, the free ends of the two clamps 306 are bent in opposite directions, that is, bent in the direction away from the gap 307, forming a structure similar to a barb, thereby enhancing the firmness of the clamping of the clamp 306 and the buckle groove, and preventing the corner protector 3 and the corner bracket 4 from falling off.

[0039] Reference Figure 3 , Figure 4 and Figure 5In this embodiment, the first covering surface 301 and the second covering surface 302 of the corner protector 3 are both provided with a plurality of reinforcing structures, and the two ends of the reinforcing structures extend to the third covering surface 303 and the fourth covering surface 304 respectively. Specifically, the reinforcing structure is an arc-shaped structure protruding outward, and the plurality of arc-shaped structures are distributed at intervals. The arc-shaped structure protruding outward can improve the structural strength of the first covering surface 301 and the second covering surface 302 of the corner protector 3, and improve the deformation resistance of the corner protector 3 under impact. It should be noted that the corner protector 3 is made of plastic, mainly PPO plastic, which has the advantages of high rigidity, high heat resistance, wear resistance and pollution resistance, and is suitable for coping with the complex outdoor environment of photovoltaic components.
