Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and particularly relates to a fastener for photovoltaic modules, and also relates to a BIPV system including the above-mentioned fastener for photovoltaic modules. Background Art

[0002] Building Integrated Photovoltaic (BIPV) is a technology that integrates photovoltaic modules into buildings.

[0003] In order to facilitate the installation of photovoltaic modules, existing BIPV systems need to customize the profile of color-coated steel tiles. Therefore, additional mold opening or even the development of new processing equipment is required, which results in high costs when the demand for color-coated steel tiles is small.

[0004] Therefore, how to provide a fastener that can fix photovoltaic modules on conventional roofing tile profiles to reduce the cost of BIPV systems is a technical problem that those skilled in the art need to solve at present. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a fastener for photovoltaic modules and a BIPV system, which are not only convenient for installation but also can reduce the cost of the BIPV system.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] A fastener for photovoltaic modules includes a support, two V-shaped clamping plates, a support block, and a bolt;

[0008] The support includes a flat plate and vertical plates respectively arranged on both sides of the bottom of the flat plate, and the bottom surfaces at both ends of the flat plate are used to contact the upper surface of the photovoltaic module;

[0009] The two V-shaped clamping plates are respectively horizontally arranged inside the two vertical plates and are hinged to the vertical plates. The openings of the V-shaped clamping plates are arranged opposite to each other, and both sides of the support block are in contact with the upper inclined plates of the two horizontally arranged V-shaped clamping plates;

[0010] The bolt is sequentially threadedly connected to the flat plate and the support block. The bolt is used to control the upward movement of the support block, thereby driving the rotation of the V-shaped clamping plate to clamp on the side of the corrugation.

[0011] Preferably, a circular opening groove is provided inside the vertical plate, and a cylinder is provided at the bottom of the tip of the V-shaped clamping plate. The cylinder is hinged in the circular opening groove.

[0012] Preferably, both side surfaces of the support block are inclined surfaces that are in surface contact with the V-shaped clamping plate.

[0013] Preferably, the width of the support block between the V-shaped clamping plates is smaller than its length along the extending direction of the corrugation.

[0014] Preferably, anti-slip layers are provided on the bottom surfaces at both ends of the flat plate.

[0015] A BIPV system includes the photovoltaic module fastener described in any one of the above.

[0016] Compared with the prior art, the above technical solution has the following advantages:

[0017] A photovoltaic module fastener and a BIPV system provided by the present invention include a support, two V-shaped clamping plates, a support block, and a bolt; the support includes a flat plate and vertical plates respectively provided on both sides of the bottom of the flat plate, and the bottom surfaces at both ends of the flat plate are used to contact the upper surface of the photovoltaic module; the two V-shaped clamping plates are respectively horizontally arranged inside the two vertical plates and are hinged to the vertical plates, and the openings of the V-shaped clamping plates are arranged oppositely; the bolt is in threaded connection with the flat plate and the support block in sequence.

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. 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.

[0025] Please refer to Figures 1 to 3 , Figure 1 which is an exploded view of a photovoltaic module fastener provided by a specific embodiment of the present invention; Figure 2 which is a schematic structural diagram of a BIPV system provided by a specific embodiment of the present invention; Figure 3 is Figure 2 an enlarged view of area A in

[0026] A photovoltaic module fastener provided by an embodiment of the present invention includes a π-shaped support 304, two V-shaped clamping plates 305, a support block 303, and a bolt 301; the support 304 has a structure with a cross-section similar to π, which includes a flat plate and vertical plates respectively arranged on both sides of the bottom of the flat plate. The height of the vertical plates of the support 304 is slightly less than the thickness of the photovoltaic module 2, and the bottom surfaces at both ends of the flat plate are used to contact the upper surface of the photovoltaic module 2; the two V-shaped clamping plates 305 are respectively horizontally arranged inside the two vertical plates and are hinged to the vertical plates, and the openings of the V-shaped clamping plates 305 are arranged opposite to each other; the bolt 301 is sequentially threadedly connected to the flat plate and the support block 303. When installing the photovoltaic module 2, the support 304 carrying the V-shaped clamping plates 305 is clamped on the corrugation 101, the wedge block is placed on the upper part of the corrugation 101 and is located between the two V-shaped clamping plates 305, and then the bolt 301 is sequentially screwed onto the upper plate of the support 304 and the support block 303. In order to prevent loosening, a spring washer 302 is sleeved on the bolt 301. As the bolt 301 is screwed, the support block 303 will gradually move upward until it contacts the upper inclined plate of the horizontally arranged V-shaped clamping plate 305. Continuing to screw the bolt 301, the two V-shaped clamping plates 305 rotate to clamp on the side surface of the corrugation 101. Through this fastener 3, the selection of a conventional angled tile-shaped color steel tile 1 can meet the installation of the photovoltaic module 2, so the cost is relatively low, the applicability is strong, and during installation, by screwing the bolt 301, the fixation of the fastener and the fixation of the photovoltaic module 2 can be achieved, so the installation is relatively convenient.

[0027] Specifically, a circular opening groove is provided inside the vertical plate, and a cylinder is provided at the bottom of the tip of the V-shaped clamping plate 305, and the cylinder is hinged in the circular opening groove. When installing the V-shaped clamping plate 305, it can be gradually inserted from one end of the opening groove. When the bolt 301 is screwed, the support block 303 will drive the V-shaped clamping plate 305 to rotate around the cylinder as the rotation axis and clamp on the side surface of the corrugation 101.

[0028] Furthermore, the two side surfaces of the supporting block 303 are inclined surfaces that are in surface contact with the V-shaped clamping plate 305. By the surface contact between the supporting block 303 and the V-shaped clamping plate 305, the connection and fixation of the fastener can be improved.

[0029] Among them, the supporting block 303 is preferably a rectangular plate-like structure. To prevent the supporting block 303 from rotating self when screwing the bolt 301, the width of the supporting block 303 is less than its length, that is, the width of the supporting block 303 located between the V-shaped clamping plates 305 is less than its length along the extending direction of the corrugation 101.

[0030] Furthermore, anti-slip layers are provided on the bottom surfaces at both ends of the flat plate. The anti-slip layer can be patterns such as serrated or wavy. Through the anti-slip layer, the friction between the flat plate and the photovoltaic module 2 can be increased, thereby ensuring the stability of the installation of the photovoltaic module 2.

[0031] To facilitate the clamping of the fastener on the corrugation 101, the weight of the upper inclined plate of the horizontally placed V-shaped clamping plate 305 is less than that of the lower inclined plate, that is, in the natural state, the lower inclined plate of the V-shaped clamping plate 305 is almost in a vertical state, which is convenient for directly clamping on the corrugation 101. In addition, the cross-section of the V-shaped clamping plate 305 is preferably an eccentric cross-section, which facilitates the V-shaped clamping plate 305 to rotate a small angle around the fulcrum to achieve a large range of movement of the lower inclined plate.

[0032] The embodiment of the present invention also provides a BIPV system, including a color steel tile 1, a photovoltaic module 2, and the photovoltaic module fastener 3 provided in any of the above embodiments. The beneficial effects can be referred to the above photovoltaic module fastener 3 and will not be elaborated here.

[0033] In this specification, the various embodiments are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same or similar parts among the various embodiments can be referred to each other.

[0034] The above has introduced in detail a photovoltaic module fastener and a BIPV system provided by the present invention. Specific examples are used herein to elaborate the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the protection scope of the claims of the present invention.
