[0032] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] As Figures 1 - 4 shown, an embodiment of the present utility model provides a dust-proof photovoltaic module, including a rectangular frame and a photovoltaic panel 1, and the photovoltaic panel 1 is installed in the rectangular frame;

[0034] The rectangular frame includes two first frames 2 and two second frames 3. The two first frames 2 are parallel to each other, and each first frame 2 is perpendicular to each second frame 3. The first frame 2 and the second frame 3 are connected;

[0035] A notch 201 for discharging dust is provided on each first frame 2.

[0036] The two second frames 3 are parallel to each other.

[0037] Specifically, a notch 201 is provided on the first frame 2, so that the dust and sundries on the photovoltaic panel 1 can be discharged from the notch 201, and it is not easy to accumulate on the surface of the photovoltaic module to form a dust accumulation zone, and thus it is not easy to affect the power generation performance of the photovoltaic module. Furthermore, the power generation income of the photovoltaic power station is effectively improved, the frequency and cost of cleaning the photovoltaic module are reduced, and the operation and maintenance efficiency of the power station is improved.

[0038] According to an embodiment of the present utility model, as Figure 3 shown, the first frame 2 includes a first plate body 202, a second plate body 203 and a third plate body 204 that are sequentially connected;

[0039] The first plate body 202 and the third plate body 204 are located on the same side of the second plate body 203;

[0040] The first plate body 202 is parallel to the third plate body 204, and the first plate body 202 is perpendicular to the second plate body 203;

[0041] A bearing plate 205 is provided between the first plate body 202 and the third plate body 204;

[0042] One side of the bearing plate 205 is fixedly connected to the second plate body 203, and a receiving cavity 206 for receiving the photovoltaic panel 1 is formed between the bearing plate 205 and the first plate body 202;

[0043] The first plate body 202 is provided with a notch 201.

[0044] The bearing plate 205 is parallel to the first plate body 202.

[0045] When the glass surface of the photovoltaic panel 1 in the photovoltaic module faces upward (the glass surface is denoted as the upper surface of the photovoltaic panel 1) and is parallel to the horizontal plane, at this time, the gap surrounded by the side wall of the first plate body 202, the upper surface of the second plate body 203, and the side surface of the second frame 3 in contact with the second plate body 203 is the notch 201, and the upper surface of the second plate body 203 is not higher than the glass surface of the photovoltaic panel 1 (that is, the surface of the notch 201 is not higher than the glass surface), so that dust can be discharged more smoothly.

[0046] According to an embodiment of the present invention, the surface of the first plate body 202 away from the second plate body 203 is an arc surface.

[0047] According to an embodiment of the present invention, two notches 201 are symmetrically provided on each first frame 2.

[0048] Since the photovoltaic module is generally installed on the top of an inclined bracket for use, when the notches 201 are symmetrically arranged, there is no restriction on the installation direction of the photovoltaic module, and the dust and impurities on the photovoltaic panel 1 in the photovoltaic module can all be smoothly discharged through the notches 201, and the effect is better.

[0049] For the convenience of description, the surface of the first plate body 202 away from the second plate body 203 is denoted as the first surface, and the surface opposite to the first surface is the second surface. When the notches 201 are symmetrically provided at both ends of the first plate body 202 and the first surface is an arc surface, the distance from the middle of the arc surface to the second surface is greater than the distance from both ends of the arc surface to the second surface. The design of the arc surface can better conform to fluid mechanics, and thus can facilitate the dust and other impurities on the photovoltaic panel 1 to flow out of the glass surface of the photovoltaic panel 1 from the notch 201 more quickly.

[0050] Of course, in this embodiment, the notch 201 can also be located at other positions. The notch 201 is opened at the middle position of the first plate body 202. At this time, the distance from the end of the arc surface close to the notch 201 to the second surface is less than the distance from the other end to the second surface. Its gist does not depart from the design concept of the present utility model. Therefore, it should fall within the protection scope of the present utility model.

[0051] Of course, in this embodiment, the first surface can also be a plane. The two surfaces connected to both sides of the first surface are the third surface and the fourth surface. The third surface is the surface of the first plate body 202 away from the carrier plate 205. The third surface is perpendicular to the first surface, and an obtuse angle is formed between the fourth surface and the first surface. Furthermore, it can play a role in guiding and guiding the flow when installing the photovoltaic panel 1. Its gist does not depart from the design concept of the present utility model. Therefore, it should fall within the protection scope of the present utility model.

[0052] According to an embodiment of the present utility model, as Figure 3 shown, a first glue storage groove 207 is opened on the side of the first plate body 202 close to the carrier plate 205. The first glue storage groove 207 communicates with the accommodation cavity 206.

[0053] When installing the first frame 2 and the second frame 3 around the photovoltaic panel 1, since it is connected by silicone sealant, the silicone sealant is squeezed into the accommodation cavity 206. When one side of the photovoltaic panel 1 is inserted into the accommodation cavity 206, the silicone sealant is squeezed, and it is easy to have the situation of glue overflow. Therefore, by providing the first glue storage groove 207, the situation of glue overflow between the upper surface of the photovoltaic panel 1 and the first plate body 202 can be reduced to a certain extent.

[0054] According to an embodiment of the present utility model, the first glue storage groove 207 has a first side wall and a second side wall. The first side wall is parallel to the first plate body 202, and an included angle is formed between the first side wall and the second side wall, and the included angle is an acute angle.

[0055] The included angle between the first side wall and the second side wall in the first glue storage groove 207 is set to be an acute angle, so that the flow direction of the colloid in the first glue storage groove 207 flows towards the second plate body 203. Furthermore, while better fixing the photovoltaic panel 1 and the first frame 2, it can also reduce the situation of silicone sealant overflowing from the gap between the first plate body 202 and the photovoltaic panel 1.

[0056] According to an embodiment of the present utility model, a plurality of first glue storage grooves 207 are provided. Providing a plurality of first glue storage grooves 207 has a better anti-glue overflow effect.

[0057] According to an embodiment of the present utility model, retaining pieces are fixedly connected to both ends of the first plate body 202.

[0058] The blocking piece can prevent the colloid in the first glue storage groove 207 from overflowing.

[0059] According to an embodiment of the present invention, a second glue storage groove 208 is opened on one side of the second plate body 203 , and the second glue storage groove 208 is communicated with the accommodating cavity 206 .

[0060] The second glue storage groove 208 can reduce the occurrence of glue overflow between the side surface of the photovoltaic panel 1 and the second plate body 203 .

[0061] According to an embodiment of the present invention, a support plate for supporting the carrying plate 205 is fixedly connected to a side of the carrying plate 205 away from the second plate body 203 .

[0062] The support plate provided can make the load-bearing effect of the support plate 205 better and less prone to deformation, thereby enhancing the stability of the support plate 205 for the photovoltaic panel 1 .

[0063] In this embodiment, the length direction of the second plate body 203, the length direction of the third plate body 204 and the length direction of the first plate body 202 are the same, the width of the first plate body 202 is smaller than the width of the supporting plate 205, and the width of the supporting plate 205 is smaller than the width of the third plate body 204. The smaller the design width of the first plate body 202, the less it affects the power generation of the photovoltaic panel 1. The wide width of the supporting plate 205 is to be able to provide stable support for the photovoltaic panel 1.

[0064] like Figure 4 As shown, a placement cavity for accommodating the photovoltaic panel 1 is provided on the second frame 3, and the placement cavity is connected to a third glue storage groove to prevent glue overflow.

[0065] A first clearance area and a second clearance area are provided at both ends of the second frame 3. The first clearance area is used to make room for the supporting plate 205 in the first frame 2, and the second clearance area is used to make room for the third plate body 204 in the first frame 2, thereby making the connection between the first frame 2 and the second frame 3 more stable.

[0066] Specifically, silicone sealant is squeezed into the accommodation cavity 206 within the first frame 2 and the placement cavity of the second frame 3. The four side edges of the photovoltaic panel 1 are respectively placed into the corresponding accommodation cavity 206 and placement cavity. The silicone sealant fills the gaps between the photovoltaic panel 1 and the placement cavity as well as the gaps between the photovoltaic panel 1 and the accommodation cavity 206 under extrusion. The excess silicone sealant enters the first sealant storage groove 207, the second sealant storage groove 208, and the third sealant storage groove, preventing sealant overflow. After the photovoltaic panel 1 is assembled with the first frame 2 and the second frame 3, the first frame 2 and the second frame 3 are connected. Finally, the photovoltaic module is fixed on the bracket for use. Due to the opened notch 201, rainwater, dust, etc. can flow out along the notch 201, effectively improving the problem of the decline in the power generation performance of the photovoltaic panel 1 caused by dust accumulation.

It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first", "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
