Description

Technical Field

[0001] The utility model relates to the technical field of new energy, and in particular to a photovoltaic system that prevents dust accumulation. Background Art

[0002] The photovoltaic industry is developing rapidly, and photovoltaic products are gradually being applied to more and more fields. Most traditional photovoltaic products include photovoltaic panels and frames. The frames are set along the edges of the photovoltaic panels to support and protect the photovoltaic panels. In order to ensure the connection effect, the frames are mostly in contact with the two large surfaces and sides of the photovoltaic panels, thereby wrapping the entire edge. However, although this method can play the role of frame support and protection, when the surface of the photovoltaic panel is used for a long time or encounters rainy days, the dust and water on the light-receiving surface of the photovoltaic panel are blocked by the frame and cannot be separated from the light-receiving surface in time, thus accumulating on the photovoltaic panel. The photovoltaic panel cannot receive enough light, which eventually leads to a decrease in the function and efficiency of the photovoltaic product. At present, some improved frames have appeared on the market, which reduce dust and water to a certain extent by reducing the contact surface with the photovoltaic panel, but the photovoltaic panels without frame wrapping are prone to loosening, the connection effect between the photovoltaic panel and the frame is reduced, and there is a risk of falling off.

[0003] As can be seen from the above, in the prior art, there is a problem that the connection between the photovoltaic panel and the frame of the anti-dust accumulation photovoltaic product is poor. Utility Model Content

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] In order to solve the problem that the connection effect between the photovoltaic panel and the frame of the dust-proof photovoltaic product in the prior art is poor, the present invention provides a dust-proof photovoltaic system.

[0030] Embodiment 1

[0031] As Figures 1 to 6 shown, the dust-proof photovoltaic system includes a photovoltaic module 10, a frame assembly 20 and a connection assembly 30. The photovoltaic module 10 has a first surface and a second surface which are oppositely arranged. The frame assembly 20 is arranged at the edge of the photovoltaic module 10 and supports at least the second surface, and the frame assembly 20 at least avoids the first surface of the photovoltaic module 10. The connection assembly 30 penetrates through the photovoltaic module 10 and the frame assembly 20 and is used to connect the photovoltaic module 10 and the frame assembly 20.

[0032] By means of the border component 20 avoiding the first surface of the photovoltaic module 10, when it rains or there is sand and dust, dust and rainwater can flow out along the edge of the first surface without accumulation. The connecting component 30 is partially inserted through the photovoltaic module 10 and the border component 20, improving the connection effect between the photovoltaic module 10 and the border component 20, avoiding the photovoltaic module 10 detaching from the border component 20 due to the lack of connection of the border component 20 on the first surface, and improving the connection effect between the photovoltaic panel and the border of the dust-proof photovoltaic product.

[0033] As Figures 1 to 6 shown, the border component 20 includes a support frame 21. The support frame 21 is arranged around the edge of the photovoltaic module 10 and supports the second surface. The connecting component 30 is inserted through the photovoltaic module 10 and the support frame 21.

[0034] Specifically, the first surface is the side of the photovoltaic module 10 facing the sun, and the second surface is the other side of the photovoltaic module 10. The support frame 21 is arranged along the circumferential side of the photovoltaic module 10 and is located at the edge of the second surface. Compared with the support frame 21 being arranged on the entire second surface, the present application can reduce the cost of the support frame 21. Connecting holes are provided on both the photovoltaic module 10 and the support frame 21. The connecting component 30 passes through the connecting holes to connect the support frame 21 and the photovoltaic module 10, preventing the photovoltaic module 10 from sliding on the support frame 21.

[0035] As Figure 3 and Figure 6 shown, a receiving groove 211 is provided on the side of the support frame 21 away from the photovoltaic module 10. At least a part of the connecting component 30 is received in the receiving groove 211.

[0036] Specifically, the receiving groove 211 is formed by the depression of the bottom edge of the support frame 21, and a through hole adapted to the connecting component 30 is provided on the receiving groove 211.

[0037] In this embodiment, the opening of the receiving groove 211 is arranged in the direction away from the second surface of the photovoltaic module 10, and the end of the connecting component 30 extending into the receiving groove 211 does not protrude from the opening of the receiving groove 211.

[0038] Specifically, the receiving groove 211 is a groove with an opening facing downwards and a cross-section in an inverted U shape. The length of the part of the connecting component 30 located in the receiving groove 211 is less than the depth of the receiving groove 211, so that when the distance between the photovoltaic system and the ground is small, the connecting component 30 will not interfere with the assembly of the photovoltaic product.

[0039] As Figures 1 to 6As shown, the connecting component 30 includes a connecting piece 31 and a fastening piece 32. The first end of the connecting piece 31 has a pressing structure 311. The fastening piece 32 is detachably arranged at the second end of the connecting piece 31. Wherein, the connecting piece 31 sequentially passes through the photovoltaic module 10 and the support frame 21, so that the pressing structure 311 abuts against the first surface of the photovoltaic module 10. The fastening piece 32 is accommodated in the accommodating groove 211 and can be locked with the second end of the connecting piece 31.

[0040] Specifically, the connecting piece 31 sequentially passes through the connecting holes on the photovoltaic module 10 and the support frame 21 and is connected to the fastening piece 32 in the accommodating groove 211. The photovoltaic module 10 and the support frame 21 are firmly connected through the cooperation between the connecting piece 31 and the fastening piece 32. The way that the pressing structure 311 abuts against the first surface enables only one pressing structure 311 to be arranged at the edge of the first surface. Dust and accumulated water on the first surface can easily flow around the pressing structure 311 without accumulating on the first surface to interfere with the first surface's absorption of sunlight. Optionally, the connecting piece 31 is located in the middle of the edge of the photovoltaic module 10. Of course, it can also be at other positions of the photovoltaic module 10.

[0041] In this embodiment, the connecting piece 31 is a screw and the fastening piece 32 is a nut. The photovoltaic module 10 and the support frame 21 can be fastened through the cooperation between the screw and the nut.

[0042] In another embodiment not shown in the present application, the connecting piece 31 sequentially passes through the support frame 21 and the photovoltaic module 10, so that the pressing structure 311 is accommodated in the accommodating groove 211 and presses the support frame 21, and the fastening piece 32 abuts against the first surface of the photovoltaic module 10.

[0043] Specifically, during installation, the connecting piece 31 passes through from bottom to top and is connected to the fastening piece 32 arranged on the first surface. In this installation method, the pressing structure 311 presses the bottom of the accommodating groove 211, and the fastening piece 32 is connected to the other end of the connecting piece 31, and the installation is convenient. Optionally, the fastening piece 32 is a self-locking nut.

[0044] As Figures 1 to 6 shown, the connecting component 30 further includes a gasket 33. When the pressing structure 311 is located at the first surface, the gasket 33 is arranged between the pressing structure 311 and the first surface; or when the fastening piece 32 is located at the first surface, the gasket 33 is arranged between the fastening piece 32 and the first surface.

[0045] Specifically, when the pressing structure 311 of the connecting member 31 abuts against the first surface, since the photovoltaic module 10 mostly adopts a glass plate structure, in order to ensure that the connecting member 31 does not damage the first surface of the photovoltaic module 10 during actual installation, thereby reducing the service life of the photovoltaic module 10, a gasket 33 is provided between the pressing structure 311 and the first surface; the gasket 33 is preferably made of silica gel or rubber to play a buffering role when the connecting member 31 cooperates with the fastener 32. When the fastener 32 is provided on the first surface, the gasket 33 can also be used to protect the first surface. Optionally, whether the fastener 32 is provided on the first surface, a gasket 33 is provided between the fastener 32 and the first surface as well as between the pressing structure 311 and the bottom of the receiving groove 211.

[0046] In this embodiment, the side surface of the photovoltaic module 10 is flush with or protrudes from the outer edge of the support frame 21.

[0047] Specifically, the outer edge of the support frame 21 being flush with the side surface of the photovoltaic module 10 can prevent accumulated water from flowing along the side surface of the photovoltaic module 10 into the space between the support frame 21 and the second surface to form accumulated water, and can also achieve the aesthetics of the photovoltaic system. Optionally, a drainage hole is provided on one side of the support frame 21 close to the photovoltaic module 10 to prevent accumulated water. When the photovoltaic module 10 protrudes from the outer edge of the support frame 21, the photovoltaic module 10 and the support frame 21 as a whole are in a T shape, and the support frame 21 is hidden under the photovoltaic module 10, which can further improve the aesthetics of the photovoltaic system.

[0048] Embodiment Two

[0049] The difference between Embodiment Two and Embodiment One is that the frame assembly 20 in Embodiment Two further includes a side plate 22.

[0050] As Figures 4 to 6 shown, the frame assembly 20 further includes a side plate 22. The side plate 22 is provided at the outer edge of the support frame 21 and corresponds to the side surface of the photovoltaic module 10, and one end of the side plate 22 close to the first surface abuts against the side surface of the photovoltaic module 10.

[0051] Specifically, the side plate 22 is provided on the support frame 21. By abutting the side plate 22 against the side surface of the photovoltaic module 10, a stop positioning is formed for the extension direction of the photovoltaic module 10 on the first surface, preventing the photovoltaic module 10 from sliding along the extension direction of the first surface and improving the stability of the photovoltaic system.

[0052] In this embodiment, the side plate 22 is disposed at an angle with the side surface of the photovoltaic module 10; and / or one end of the side plate 22 close to the first surface does not protrude beyond the first surface.

[0053] Specifically, the side panels 22 are arranged at an angle to the side of the photovoltaic module 10 to better stop the photovoltaic module 10, and the side panels 22 are arranged not to protrude from the first surface to prevent water and dust from accumulating on the first surface. At the same time, the water on the first surface can be quickly drained along the side panels 22 to prevent water from accumulating between the support frame 21 and the second surface.

[0054] In this embodiment, the outer edge of the support frame 21 is parallel to the side of the photovoltaic assembly 10 and is spaced apart.

[0055] Specifically, in this way, the side panels 22 can be better matched, and the side panels 22 and the support frame 21 are formed in one piece.

[0056] In this embodiment, there are one or more side panels 22, which are continuously arranged around the periphery of the support frame 21; or multiple side panels 22 are arranged at intervals around the periphery of the support frame 21; or only one side panel 22 is arranged on at least one side of the support frame 21.

[0057] Specifically, when there is one side panel 22, one side panel 22 can be arranged at any side surface of the photovoltaic module 10, and the other side surfaces are flush with the outer edge of the support frame 21. When there are two side panels 22, the two side panels 22 can be arranged at two opposite or adjacent side surfaces of the photovoltaic module 10. When the number of the side panels 22 and the side surfaces of the photovoltaic module 10 is the same, the multiple side panels 22 are connected in sequence and arranged around the circumferential side surface of the photovoltaic module 10.

[0058] From the above description, it can be seen that the above-mentioned embodiments of the utility model achieve the following technical effects: by setting an anti-dust photovoltaic system including a photovoltaic component 10, a frame component 20 and a connecting component 30, the photovoltaic component 10 has a first surface and a second surface that are relatively arranged, the frame component 20 is arranged at the edge of the photovoltaic component 10 and at least supports the second surface, and the frame component 20 at least avoids the first surface of the photovoltaic component 10, the connecting component 30 is penetrated on the photovoltaic component 10 and the frame component 20, and is used to connect the photovoltaic component 10 and the frame component 20, and the frame component 20 avoids the first surface of the photovoltaic component 10, so that when the first surface of the photovoltaic component 10 encounters rainy days or windy and sandy days, dust and rainwater can flow out along the edge of the first surface without accumulation, and the connecting component 30 is partially penetrated on the photovoltaic component 10 and the frame component 20, so as to improve the connection effect between the photovoltaic component 10 and the frame component 20, avoid the photovoltaic component 10 from being separated from the frame component 20 due to the lack of connection of the frame component 20 on the first surface, and improve the connection effect between the photovoltaic panel and the frame of the anti-dust photovoltaic product.
