Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and in particular to photovoltaic devices. Background Technology

[0002] Building-integrated photovoltaics (BIPV) projects involve installing photovoltaic (PV) devices on the roof of a building to generate electricity using solar photovoltaic technology, aiming to achieve energy conservation and emission reduction. However, due to limitations imposed by the building's roof structure, it may not be possible to cover all areas with PV tiles during installation. In areas unsuitable for PV tiles, additional shading tiles are typically installed, and the connection between the PV tiles and these additional shading tiles is a crucial step.

[0003] Traditional photovoltaic (PV) systems have drainage channels at the connection between the photovoltaic tiles and the supporting tiles. Water accumulated on both tiles flows into these channels and is then drained away. However, excessive water accumulation in the drainage channels can easily lead to leaks, negatively impacting the stability and lifespan of both the PV tiles and the building. Utility Model Content

[0004] Therefore, it is necessary to provide a photovoltaic device that can reduce the accumulation of water on the tiles and photovoltaic tiles into the drainage channel, and allow more water to drain out along the surface of the tiles and photovoltaic tiles.

Simultaneously, the frame also partially covers the drainage channel, reducing the coverage area of ​​auxiliary components and saving materials.

[0014] In one embodiment, the auxiliary component is sealed to the frame; and / or

[0015] The auxiliary component is sealed to the tile.

At the same time, it improves the installation convenience and firmness of the auxiliary component between the photovoltaic tile and the matching tile.

[0022] In one embodiment, a sealing groove is provided on the side of the first connecting part facing the groove wall to which it is connected, and a first sealing element is provided in the sealing groove, and the first sealing element protrudes from the sealing groove to be sandwiched between the first connecting part and the groove wall.

[0046] See Figures 1-3 , Figure 1 A partial structural schematic diagram of a photovoltaic device provided in one embodiment of this application is shown; Figure 2 It shows Figure 1 Enlarged structural diagram at point A in the middle; Figure 3 A schematic diagram of the structure of the auxiliary component 4 provided in one embodiment of this application is shown.

[0047] This application provides a photovoltaic device, which includes a photovoltaic tile 1, a distribution tile 3, and an auxiliary component 4. The photovoltaic tile 1 has a frame 2 along its edge. The distribution tile 3 is connected to the photovoltaic tile 1, and at least one end of the distribution tile 3 connected to the photovoltaic tile 1 has a drainage groove 31. The auxiliary component 4 is connected to the frame 2 and / or the distribution tile 3, and the auxiliary component 4 covers the opening of the drainage groove 31.

[0048] The photovoltaic device provided in this application embodiment has a drainage trough 31 at the end where the tile 3 connects to the photovoltaic tile 1. This drainage trough prevents various risks such as short circuits and corrosion caused by water accumulation at the connection point between the tile 3 and the photovoltaic tile 1. Furthermore, by providing an auxiliary component 4 to cover the opening of the drainage trough 31, water accumulation on the tile 3 and photovoltaic tile 1 is blocked, allowing more water to drain along the surfaces of the tile 3 and photovoltaic tile 1, reducing the amount of water accumulating in the drainage trough 31. This reduces the amount of water accumulating in the drainage trough 31, which helps alleviate leakage problems caused by excessive water accumulation, thereby improving the stability and service life of the photovoltaic device and the building.

[0049] In some embodiments, the auxiliary component 4 is detachably connected to the frame 2 and to the supporting tile 3 to facilitate the replacement or repair of the photovoltaic tile 1 or the supporting tile 3 individually.

[0050] Specifically, the frame 2 is provided with an installation groove, and the edge of the photovoltaic tile 1 is engaged in the installation groove to securely install the frame 2 onto the photovoltaic tile 1.

[0051] Optionally, a second sealing element 11 is sandwiched between the frame 2 and the photovoltaic tile 1 to improve the sealing of the connection between the frame 2 and the photovoltaic tile 1, so as to prevent the penetration of liquids such as rainwater.

[0052] Specifically, before assembling the frame 2 and the photovoltaic tile 1, sealant is applied to the mounting groove or the photovoltaic tile 1. After the frame 2 and the photovoltaic tile 1 are inserted, the sealant is allowed to solidify to form the aforementioned second sealing element 11. Of course, the second sealing element 11 can also be a sealing gasket structure, which can also achieve a good sealing effect.

[0053] In some embodiments, the surfaces of the auxiliary component 4, the frame 2, and the tile 3 are flush on the light-receiving surface of the photovoltaic device. This makes the overall light-receiving surface of the photovoltaic device flatter and more harmonious, achieving a better appearance.

[0054] In some embodiments, the frame 2 is partially inserted into the drainage groove 31, and the auxiliary component 4 is connected to the frame 2 inserted into the drainage groove 31, with the auxiliary component 4 and the frame 2 cooperating to cover the opening of the drainage groove 31. By inserting the frame 2 into the drainage groove 31, the end of the tile 3 overlaps the lower side of the frame 2, facilitating the connection and fixation between the two. At the same time, the frame 2 can also partially cover the drainage groove 31, which helps to reduce the coverage area of ​​the auxiliary component 4 and save materials.

[0055] Specifically, a slot 22 is provided on the back side of the frame 2, and the wall of the drainage groove 31 is inserted into the slot 22 so that the frame 2 and the tile 3 are connected by insertion.

[0056] It should be noted that the frame 2 on one side of the photovoltaic tile 1 can be configured with the aforementioned structure having a slot 22, and the frame 2 on the opposite side of the photovoltaic tile 1 can be configured with a matching insertion protrusion, so that adjacent photovoltaic tiles 1 can be directly connected by insertion. When the photovoltaic tile 1 is connected to the supporting tile 3 and the auxiliary component 4 is set between the photovoltaic tile 1 and the supporting tile 3, no additional structural design is required for the photovoltaic tile 1, simplifying the processing steps.

[0057] In some embodiments, the auxiliary component 4 is sealed to the frame 2; and / or the auxiliary component 4 is sealed to the tile 3. This sealed connection improves the resistance to liquids such as rainwater, significantly enhancing the sealing performance between the photovoltaic tile 1 and the tile 3.

[0058] In some embodiments, the auxiliary component 4 includes a cover portion 41, a first connecting portion 42, and a second connecting portion 43. The cover portion 41 covers the opening of the drainage channel 31. The first connecting portion 42 is connected to the cover portion 41, inserted into the drainage channel 31, and sealed to the channel wall of the drainage channel 31 away from the frame 2. The second connecting portion 43 is connected to the cover portion 41, inserted into the drainage channel 31, and sealed to the frame 2. Through the above structural improvement of the auxiliary component 4, the cover portion 41 covers the drainage channel 31, and through the sealed connection between the first connecting portion 42 and the channel wall of the drainage channel 31, and the sealed connection between the second connecting portion 43 and the frame 2, the auxiliary component 4 achieves a sealed cover of the drainage channel 31, while improving the installation convenience and firmness of the auxiliary component 4 between the photovoltaic tile 1 and the supporting tile 3.

[0059] Specifically, on the light-receiving side of the photovoltaic device, the surfaces of the cover 41, the frame 2, and the tile 3 are kept flush.

[0060] Optionally, the cover portion 41, the first connecting portion 42, and the second connecting portion 43 are configured as an integral structure and can be integrally processed by injection molding.

[0061] Specifically, the auxiliary component 4 can be made entirely of a sealing material with a certain degree of elasticity and weather resistance, such as rubber or silicone, to achieve a good sealing effect and make it easier to process and mold.

[0062] In some embodiments, a first sealing element 44 is sandwiched between the first connecting portion 42 and the wall of the sealing groove 421 and the drainage groove 31 to further improve the sealing performance between the auxiliary component 4 and the tile 3. The first sealing element 44 may be a sealing strip.

[0063] Optionally, a sealing groove 421 is provided on the side of the first connecting part 42 facing the wall of the drainage groove 31 to which it is connected. A first sealing element 44 is provided in the sealing groove 421, and the first sealing element 44 protrudes from the sealing groove 421 to be sandwiched between the first connecting part 42 and the groove wall. The sealing groove 421 is provided to limit the installation of the first sealing element 44, so that the first sealing element 44 is firmly installed.

[0064] Optionally, a limiting protrusion 422 is provided on the opening of the sealing groove 421 facing the inside of the sealing groove 421. The limiting protrusion 422 is used to restrict the first sealing element 44 from coming out of the sealing groove 421, thereby further improving the installation firmness of the first sealing element 44 and helping the first sealing element 44 to play a more stable sealing role.

[0065] In some embodiments, the end of the second connecting portion 43 away from the covering portion 41 is bent to form an insertion groove 431, and the frame 2 is inserted into the insertion groove 431. The connection between the auxiliary component 4 and the frame 2 is strengthened by the insertion and engagement method.

[0066] Optionally, a sealing element may be sandwiched between the second connecting part 43 and the frame 2 to improve the sealing performance of the connection between the two.

[0067] In some embodiments, the end of the second connecting portion 43 away from the cover portion 41 is snapped into the frame 2. This snap-fit ​​method improves the connection strength between the second connecting portion 43 and the frame 2.

[0068] Optionally, the end of the second connecting part 43 away from the cover part 41 is configured as a first mating part 432, and a corresponding second mating part 21 is provided on the frame 2, and the first mating part 432 and the second mating part 21 are engaged and connected.

[0069] Specifically, the first mating part 432 is constructed as a T-shaped protrusion, and the second mating part 21 is constructed as a T-shaped slot. The T-shaped protrusion and the T-shaped slot engage with each other, thereby further improving the connection strength between the second connecting part 43 and the frame 2.

[0070] When assembling the photovoltaic device, the frame 2 can be installed on the photovoltaic tile 1 first, and then the auxiliary component 4 can be assembled on the frame 2; alternatively, the auxiliary component 4 and the frame 2 can be assembled first, and then the auxiliary component 4 and the frame 2 can be assembled together on the photovoltaic tile 1. When assembling the auxiliary component 4 with the frame 2, align the first mating part 432 with the second mating part 21, and then push the auxiliary component 4 along the extension direction of the second mating part 21 until the first mating part 432 is fully inserted into the second mating part 21.

[0071] After the photovoltaic tile 1, frame 2 and auxiliary parts 4 are assembled, they are then assembled with the matching tile 3. One end of the drainage groove 31 of the matching tile 3 is attached to the lower side of the auxiliary part 4. One wall of the drainage groove 31 is inserted into the slot 22, and the other wall is sealed to the first sealing part 44, thus realizing the assembly of the photovoltaic tile 1 and the matching tile 3.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
