Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component manufacturing, in particular to a photovoltaic tile and a photovoltaic tile building system. Background Art

[0002] Currently, the substrates of photovoltaic tiles are often uneven in shape to create space for heat dissipation of the photovoltaic panels. This makes the manufacturing process of the photovoltaic tile substrates complex and reduces production efficiency.

[0003] Therefore, how to design a photovoltaic tile that can ensure good heat dissipation performance of the photovoltaic panel while reducing the difficulty of substrate processing has become an urgent problem to be solved. Utility Model Content

[0004] The utility model aims to at least solve the problem of complex manufacturing process of photovoltaic tile substrates existing in the prior art or related technologies.

[0005] To this end, a first aspect of the present invention provides a photovoltaic tile.

[0006] A second aspect of the present invention provides a photovoltaic tile building system.

[0007] In view of this, the first aspect of the present invention proposes a photovoltaic tile, comprising: a base plate; a photovoltaic panel, arranged on one side of the base plate; a spacer, arranged between the base plate and the photovoltaic panel, for separating the base plate and the photovoltaic panel; and a connector, for connecting the base plate and the photovoltaic panel.

[0008] The photovoltaic tile provided by the present invention includes a photovoltaic panel and a base plate, the two of which are connected by a connector to securely mount the photovoltaic panel on the base plate. The photovoltaic panel is a structure that utilizes solar energy to convert photoelectric energy. Furthermore, a spacer is provided between the photovoltaic panel and the base plate to create a gap between the photovoltaic panel and the base plate, thereby forming a good heat dissipation space and improving the heat dissipation efficiency of the photovoltaic panel. Because the present application uses a spacer to isolate the photovoltaic panel and the base plate to form a heat dissipation space, there is no need to change the shape of the base plate. That is, the base plate can be directly made of a flat plate, which facilitates base plate processing, reduces processing time, and thus improves processing efficiency.

[0009] The photovoltaic tile provided by the present invention may also have the following additional technical features:

[0010] In some embodiments, optionally, a spacer is mounted on the connector.

[0011] In this embodiment, since the spacer is directly mounted on the connector, the connector and the spacer between the base plate and the photovoltaic panel can be well integrated together, so that the overall structure of the photovoltaic tile is more compact and the product volume is reduced.

[0012] In some embodiments, optionally, through holes are provided on the photovoltaic panel, and the connecting member includes: a first connecting column, mounted on the bottom plate, and one end of the first connecting column away from the bottom plate is inserted into and extends out of the through hole; a first fastener, disposed on the side of the photovoltaic panel away from the bottom plate, and detachably connected to the part of the first connecting column extending out of the through hole.

[0013] In this embodiment, the connecting member includes a first connecting column and a first fastener, and the two are detachably connected. In this way, when the photovoltaic panel needs to be replaced, the first fastener can be directly disassembled, facilitating the later maintenance of the photovoltaic panel. At the same time, this design also eliminates the need to separately provide a pressing plate structure on the surface of the photovoltaic panel to press the photovoltaic panel, reducing the number of parts used.

[0014] Of course, without considering the replacement of the photovoltaic panel, through holes can also be provided on the bottom plate, the first connecting column can be mounted on the photovoltaic panel, and the first fastener can be disposed on the side of the bottom plate away from the photovoltaic panel to achieve the fixed installation between the bottom plate and the photovoltaic panel.

[0015] In some embodiments, optionally, a spacer is sleeved on the first connecting column, and two ends of the spacer along the axial direction of the through hole are respectively abutted against the bottom plate and the photovoltaic panel; wherein, the height of the spacer is lower than the height of the first connecting column.

[0016] In this embodiment, the spacer has opposite ends, which are respectively abutted against the bottom plate and the photovoltaic panel, thus eliminating the need to additionally provide a support member to support the photovoltaic panel. It can be understood that the support member can not only isolate the bottom plate and the photovoltaic panel, but also play a role in supporting the photovoltaic panel. Moreover, since the spacer is directly sleeved on the first connecting column, the connecting member and the spacer between the bottom plate and the photovoltaic panel can be well integrated, making the overall structure of the photovoltaic tile more compact and reducing the product volume.

[0017] In some embodiments, optionally, the number of through holes is multiple; the number of connecting members is the same as the number of through holes, and the multiple connecting members correspond to the multiple through holes one by one.

[0018] In this embodiment, multiple through holes can be provided on the photovoltaic panel, and at the same time, multiple connecting members are used to correspond to the multiple through holes one by one, that is, multiple connecting structures are provided between the photovoltaic panel and the bottom plate, thereby well ensuring the connection strength between the two.

[0019] Optionally, the number of spacers is the same as the number of through holes, that is, a spacer is sleeved on each first connecting column, so as to achieve a better supporting effect on the photovoltaic panel.

[0020] Optionally, the bottom plate can be a square flat plate, and first connecting columns are respectively arranged at the four top corners of the square flat plate, so as to realize the fastening connection between the photovoltaic panel and the bottom plate around the bottom plate.

[0021] In some embodiments, optionally, the shape of the through hole includes one of a circular hole, a square hole, a triangular hole, a polygonal hole or a special-shaped hole.

[0022] In this embodiment, the shape of the through hole is not fixed, as long as it can allow the first connecting column to pass through.

[0023] Optionally, for the convenience of processing, the through hole is designed as a circular hole.

[0024] In some embodiments, optionally, the first connecting column includes one of a bolt, a stud or a screw.

[0025] In this embodiment, the structure of the first connecting column is not fixed, and any component with a threaded structure can be used as the first connecting column. For example, the first fastener can also be a pipe fitting with threads. The first fastener includes a nut, and the nut is used to cooperate with the first connecting column to realize the fastening connection between the bottom plate and the photovoltaic panel.

[0026] Optionally, the first connecting column is a screw, and the screw is fixedly installed on the bottom plate by means of planting the screw.

[0027] In some embodiments, optionally, the spacer is a telescopic member.

[0028] In this embodiment, the spacer can be set as a telescopic member to adjust the distance between the bottom plate and the photovoltaic panel, so as to facilitate the adjustability of the heat dissipation space between the photovoltaic panel and the bottom plate.

[0029] In some embodiments, optionally, the distance between the bottom plate and the photovoltaic panel is equal.

[0030] In this embodiment, since heat is generated when the photovoltaic panel works, when the distance between the bottom plate and the photovoltaic panel is equal, the heat can be transferred to the bottom plate more evenly, avoiding local overheating of the bottom plate, thereby improving the heat dissipation efficiency of the photovoltaic panel and prolonging the service life of the photovoltaic panel.

[0031] In some embodiments, optionally, the bottom plate is a flat plate or an arc-shaped plate, and the photovoltaic panel is a flat plate or an arc-shaped plate; the shapes of the bottom plate and the photovoltaic panel are the same.

The flat plate structure is easy to process and can improve the processing efficiency. The arc-shaped photovoltaic panel can improve the light reception efficiency to improve its power generation effect.

[0033] In some embodiments, optionally, the bottom plate includes a metal substrate, and an anti-corrosion layer is provided on the surface of the metal substrate.

[0034] In this embodiment, the metal substrate has high mechanical strength and stiffness and can be formed by processes such as stamping, rolling, and plate shearing. At the same time, an anti-corrosion layer is provided on the surface of the metal substrate to improve the corrosion resistance of the substrate. The anti-corrosion layer is, for example but not limited to, a paint layer, a galvanized layer, etc.

[0035] In some embodiments, optionally, the bottom plate and the connecting member are of an integral structure.

[0036] In this embodiment, the integral structure can make the strength between the bottom plate and the connecting member higher, thereby avoiding separation between the bottom plate and the connecting member, improving the overall strength of the photovoltaic tile, and at the same time, it can also simplify the processing process flow.

[0037] In some embodiments, optionally, the bottom plate and the spacer are of an integral structure.

[0038] In this embodiment, the integral structure can make the strength between the bottom plate and the spacer higher, and at the same time, it can also simplify the processing process flow.

However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0052] Next, refer to Figures 1 to 5 Describe a photovoltaic tile and a photovoltaic tile building system according to some embodiments of the present utility model.

[0054] The photovoltaic tile 1 provided by the present utility model includes a photovoltaic panel 18 and a bottom plate 12, and the two are connected by a connecting member 14 to fixedly install the photovoltaic panel 18 on the bottom plate 12. The photovoltaic panel 18 is a structure that uses solar energy for photovoltaic conversion. Further, a spacer 16 is disposed between the photovoltaic panel 18 and the bottom plate 12, so that there is a gap between the photovoltaic panel 18 and the bottom plate 12, forming a good heat dissipation space and improving the heat dissipation efficiency of the photovoltaic panel 18. Since the present application uses the spacer 16 to isolate the photovoltaic panel 18 and the bottom plate 12 to form a heat dissipation space, it is not necessary to change the shape of the bottom plate 12, that is, the bottom plate 12 can directly adopt a flat plate, which is convenient for processing the bottom plate 12, reduces the processing process, and thus improves the processing efficiency.

[0055] In some embodiments, optionally, as Figure 1 and Figure 4As shown, the spacer 16 is installed on the connecting member 14.

[0056] In this embodiment, since the spacer 16 is directly installed on the connecting member 14, the connecting member 14 and the spacer 16 between the bottom plate 12 and the photovoltaic panel 18 can be well integrated together, so that the overall structure of the photovoltaic tile 1 is more compact and the product volume is reduced.

[0057] In some embodiments, optionally, the spacer 16 is sleeved and installed on the connecting member 14.

In this way, when the photovoltaic panel 18 needs to be replaced, the first fastener 144 can be directly disassembled, which is convenient for the later maintenance of the photovoltaic panel 18. At the same time, this design also does not require a separate pressing plate structure to press the photovoltaic panel 18 on the surface of the photovoltaic panel 18, reducing the number of parts used.

[0062] In this embodiment, the spacer 16 has opposite ends that are respectively in contact with the bottom plate 12 and the photovoltaic panel 18, so that there is no need to additionally provide a support member to support the photovoltaic panel 18. It can be understood that the support member can not only isolate the bottom plate 12 and the photovoltaic panel 18, but also play a supporting role for the photovoltaic panel 18. Moreover, since the spacer 16 is directly sleeved and installed on the first connecting column 142, the connecting member 14 and the spacer 16 between the bottom plate 12 and the photovoltaic panel 18 can be well integrated, so that the overall structure of the photovoltaic tile 1 is more compact and the product volume is reduced.

[0065] Optionally, as Figure 1 shown, the number of isolation members is the same as the number of through holes 182, that is, one isolation member is sleeved on each first connecting column 142, so that a better supporting effect on the photovoltaic panel 18 can be achieved.

[0066] Optionally, the bottom plate 12 can be a square flat plate, and first connecting columns 142 are respectively provided at the four top corners of the square flat plate, so as to realize a firm connection between the photovoltaic panel 18 and the bottom plate 12 around the bottom plate 12.

[0067] In some embodiments, optionally, the shape of the through hole 182 includes one of a circular hole, a square hole, a triangular hole, a polygonal hole or an irregular hole.

[0068] In this embodiment, the shape of the through hole 182 is not fixed, as long as it can allow the first connecting column 142 to pass through.

[0069] Optionally, for convenience of processing, the through hole 182 is designed as a circular hole.

[0071] In this embodiment, the structure of the first connecting column 142 is not fixed. Any component with a threaded structure can be used as the first connecting column 142. For example, the first fastener 144 can also be a pipe fitting with a thread. The first fastener 144 includes a nut, which is used to cooperate with the first connecting column 142 to achieve a firm connection between the bottom plate 12 and the photovoltaic panel 18.

[0072] Optionally, the first connecting column 142 is a screw, and the screw is fixedly installed on the bottom plate 12 by means of screwing.

[0073] In some embodiments, optionally, the spacer 16 is a telescopic member.

[0075] In some embodiments, optionally, the distance between the bottom plate 12 and the photovoltaic panel 18 is equal.

[0076] In this embodiment, since heat is generated when the photovoltaic panel 18 operates, when the distance between the bottom plate 12 and the photovoltaic panel 18 is equal, the heat can be transferred to the bottom plate 12 more evenly, avoiding local overheating of the bottom plate 12, thereby improving the heat dissipation efficiency of the photovoltaic panel 18 and extending the service life of the photovoltaic panel 18.

[0077] In some embodiments, optionally, the bottom plate 12 is a flat plate or an arc-shaped plate, and the photovoltaic panel 18 is a flat plate or an arc-shaped plate; the shapes of the bottom plate 12 and the photovoltaic panel 18 are the same.

The anti-corrosion layer is, for example but not limited to, a paint layer, a galvanized layer, etc.

[0081] In some embodiments, optionally, the bottom plate 12 and the connecting member 14 are of an integral structure.

[0082] In this embodiment, the integrated structure can make the strength between the bottom plate 12 and the connecting member 14 higher, thereby avoiding the separation between the bottom plate 12 and the connecting member 14, improving the overall strength of the photovoltaic tile 1, and at the same time simplifying the processing process flow.
