Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and in particular to a user photovoltaic module. Background Technology

[0002] Residential photovoltaic modules are a type of distributed, small-scale photovoltaic power generation system, typically installed on rooftops, in factories, parking lots, and other locations. They are a form of distributed photovoltaics and have advantages such as low transmission losses and high flexibility, and are rapidly gaining popularity in China and even globally.

[0003] Current photovoltaic modules are mainly used in ground-mounted applications and consist of laminates and frames. The frames typically include a top edge, side edges, and a bottom edge, which respectively wrap around the light-receiving, side, and back-lighting edges of the laminate. The frame thickness is generally 30mm or 35mm, resulting in an overall weight of 10kg / m² for the photovoltaic module.

[0004] Traditional residential photovoltaic (PV) module installation requires first fixing brackets to the roof, and then connecting the PV modules using bolts and clamps. However, the existing bolt-clamp connection method has significant drawbacks: First, under long-term wind loads, the connection between the bolts and clamps is prone to loosening, causing the PV modules to sway and reducing their fixation reliability; second, due to the relatively heavy weight of PV modules (up to 10 kg / m²), the additional load on the roof is increased, potentially leading to roof damage and affecting the fixation reliability of the PV modules. Therefore, improving the fixation stability of existing residential PV modules is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0048] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0049] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0050] This utility model embodiment discloses a user photovoltaic module, as shown in the attached figure. Figure 1 As shown, the system includes a lower frame 1, an upper frame 2, a support rope 5, and photovoltaic tiles 6. The lower frame 1 is fixedly installed and can be fixed to the roof. The upper frame 2 is detachably connected to the lower frame 1, facilitating the installation and removal of the support rope 5. The upper frame 2 is located between two photovoltaic tiles 6, or on the outside of the photovoltaic tiles 6.

[0051] The upper frame 2 and the lower frame 1 interlock to form a rope hole 3. The support rope 5 passes through the rope hole 3 and is fixed inside the rope hole 3, thus fixing the upper frame 2 to the support rope 5 and preventing the upper frame 2 from swaying relative to the support rope 5, thereby reducing the risk of crush damage between adjacent photovoltaic tiles 6. In addition, the support rope 5 forms a suspension support structure, effectively reducing the vertical load of the user's photovoltaic modules on the roof and preventing damage to the roof structure that could lead to the user's photovoltaic modules not being securely fixed.

[0052] Both ends of the load-bearing rope 5 extend outside the rope-passing hole 3, and are fixedly installed at both ends. Specifically, the load-bearing rope 5 can be a steel wire rope or a steel stranded rope, with a diameter ranging from 6mm to 28mm, preferably 9mm, 9.5mm, 12mm, 12.7mm, 15mm, 15.2mm, and 15.7mm. Both ends of the load-bearing rope 5 are fixed to the building gable wall. Specifically, a pre-embedded steel plate with through holes is installed on the building gable wall, the end of the load-bearing rope 5 passes through the through hole, and is fixed to the pre-embedded steel plate using double bolts. The double bolts can be equipped with anti-loosening nuts, which utilize friction and mechanical locking to prevent loosening, thus preventing the bolts from loosening when the load-bearing rope 5 is under heavy load, ensuring that the load-bearing rope 5 will not slip or loosen, and improving the fixing reliability of the load-bearing rope 5.

[0053] The lower frame 1 has a lower support edge 11 on at least one side, and the upper frame 2 has an upper extrusion edge 21 on at least one side. A tile slot 4 is formed between the lower support edge 11 and the upper extrusion edge 21. The edge of the photovoltaic tile 6 is secured in the tile slot 4. The snap-fit ​​structure replaces the existing bolt connection, eliminating the problem of unstable fixing of the user's photovoltaic module caused by bolt vibration and loosening.

[0054] As one specific embodiment, as shown in the appendix Figure 1 As shown, when the upper frame 2 is located between two photovoltaic tiles 6, the lower frame 1 has two lower support edges 11 at one end facing the upper frame 2, and the two lower support edges 11 are symmetrically arranged; the top of the upper frame 2 has two upper extrusion edges 21 integrally arranged, and the two upper extrusion edges 21 are symmetrically arranged and extend in opposite directions; the two lower support edges 11 and the two upper extrusion edges 21 are respectively opposite to each other and are respectively fixed to the adjacent edges of the two adjacent sets of photovoltaic tiles 6 to support the two adjacent sets of photovoltaic tiles 6.

[0055] As one specific embodiment, as shown in the appendix Figure 4 As shown, when the upper frame 2 is located outside the photovoltaic tile 6, the lower frame 1 is provided with a lower support edge 11 at one end facing the upper frame 2, and the top of the upper frame 2 is integrally provided with an upper extrusion edge 21. The two lower support edges 11 are opposite to the upper extrusion edge 21 and are respectively fixed to the outermost edge of the outermost photovoltaic tile 6 to support the outermost photovoltaic tile 6.

[0056] In summary, this utility model utilizes a suspension support structure and a snap-fit ​​structure to effectively solve the problem of unstable fixing of existing photovoltaic modules, thereby improving the fixing reliability of photovoltaic modules.

[0057] In one specific embodiment, the lower frame 1 is provided with a lower mounting groove 12, and the upper frame 2 extends toward one end of the lower frame 1 to form an upper insertion block 22; the upper insertion block 22 is inserted into the lower mounting groove 12, so that the upper frame 2 and the lower frame 1 are detachably connected. Specifically, the upper frame 2 can be pressed into the lower mounting groove 12 by a stamping process, or the upper insertion block 22 can be slidably inserted into the lower mounting groove 12 from one open end of the lower mounting groove 12.

[0058] Lower stop teeth 13 are formed on the two opposite sides of the lower mounting groove 12, and upper stop grooves 23 are formed on the two opposite sides of the upper insertion block 22. The lower stop teeth 13 and the upper stop grooves 23 engage with each other to restrict the upper insertion block 22 from disengaging from the lower mounting groove 12, thereby ensuring a reliable connection between the upper frame 2 and the lower frame 1.

[0059] In one specific embodiment, the lower stop tooth 13 is a serrated protrusion extending along a first direction, and the lower stop tooth 13 has a lower stop surface 131 parallel to the first direction; the upper stop groove 23 is a serrated groove extending along the first direction, and the upper stop groove 23 has an upper stop surface 231 parallel to the first direction. The upper stop surface 231 and the lower stop surface 131 abut against each other along a second direction, effectively preventing the upper frame 2 from detaching from the lower frame 1 in the second direction, and enabling the upper frame 2 and the lower frame 1 to withstand a certain degree of load, and causing the upper frame 2 and the lower frame 1 to interlock and press the edge of the photovoltaic tile 6, forming a tight connection. The first direction is perpendicular to the second direction, and the first direction is parallel to the width direction of the lower mounting groove 12, while the second direction is parallel to the depth direction of the lower mounting groove 12.

[0060] Specifically, to improve reliability, the lower mounting groove 12 is provided with three lower stop teeth 13 on each of its two opposite sides, and the upper insertion block 22 is provided with three upper stop grooves 23 on each of its two opposite sides. By increasing the number of engagements between the lower stop teeth 13 and the upper stop grooves 23, the connection strength between the upper frame 2 and the lower frame 1 is improved.

[0061] In one specific embodiment, an upper locking groove 221 is formed within the upper insertion block 22, and the upper locking groove 221 and the lower mounting groove 12 form a rope threading hole 3. Specifically, the width of the upper locking groove 221 is equal to the diameter of the supporting rope 5, so that the supporting rope 5 is fixed in the upper locking groove 221 by an interference fit, avoiding the photovoltaic tile 6 from flipping with the upper frame 2 due to an excessive gap between the supporting rope 5 and the upper locking groove 221, and reducing the risk of crush damage to adjacent photovoltaic tiles 6.

[0062] The upper locking groove 221 has two groove edges that are integrally provided with upper limit edge 222 extending relative to each other in the first direction, so that the groove opening width of the upper locking groove 221 is smaller than the width of the upper locking groove 221. The two upper limit edge 222 are used to restrict the load-bearing rope 5 from leaving the upper locking groove 221, further ensuring that the load-bearing rope 5 is reliably fixed on the upper frame 2.

[0063] As one specific embodiment, the upper frame 2 is provided with a weight-reducing hole 24 extending along a third direction to reduce the weight of the upper frame 2 and the load applied vertically to the roof. The weight-reducing hole 24 can be a rectangular through hole, but is not limited to this. The first direction, the second direction, and the third direction are mutually perpendicular. The third direction mentioned in the text is parallel to the length direction of the lower mounting groove 12. Specifically, see attached... Figure 1 In this diagram, the X-axis refers to the first direction, the Z-axis refers to the second direction, and the Y-axis refers to the third direction.

[0064] To further achieve a lightweight design, both the upper frame 2 and the lower frame 1 are preferably made of aluminum alloy, thereby reducing the weight of the upper frame 2 and the lower frame 1 and thus reducing the load on the roof.

[0065] Because the photovoltaic tile 6 will change temperature under solar radiation, and different materials have different coefficients of thermal expansion, the photovoltaic tile 6 will undergo a certain deformation. Based on this, the distance between two adjacent photovoltaic tiles 6 in the first direction is greater than or equal to 10mm. This distance can be achieved by adjusting the width of the upper frame 2 and the lower frame 1. This can avoid the squeezing damage between two adjacent photovoltaic tiles 6 due to temperature changes, and can also utilize the air circulation between two adjacent photovoltaic tiles 6 to accelerate the dissipation of condensate or moisture, thereby reducing the risk of damage to electrical components due to excessive temperature.

[0066] As a specific embodiment, the user photovoltaic module also includes an upper elastic strip 7 and a lower elastic strip 8. The upper elastic strip 7 is fixed to the upper compression edge 21, and the lower elastic strip 8 is fixed to the lower support edge 11. The photovoltaic tile 6 is elastically compressed between the upper elastic strip 7 and the lower elastic strip 8. The upper elastic strip 7 and the lower elastic strip 8 fasten the photovoltaic tile 6 through their own elastic deformation capabilities, effectively absorbing the deformation of the photovoltaic tile 6 caused by thermal expansion and contraction, reducing stress concentration and structural damage caused by temperature changes, thereby improving the fixing reliability of the photovoltaic tile 6.

[0067] In one specific embodiment, the lower support edge 11 is provided with a lower locking groove 111, and the lower elastic strip 8 is provided with a lower locking protrusion 81. The lower locking groove 111 and the lower locking protrusion 81 engage with each other, and the elastic force of the lower locking protrusion 81 ensures that the lower elastic strip 8 is reliably fixed on the lower support edge 11. The upper pressing edge 21 is provided with an upper locking groove, and the upper elastic strip 7 is provided with an upper locking protrusion 71. The upper locking groove 211 and the upper locking protrusion 71 engage with each other, and the elastic force of the upper locking protrusion 71 ensures that the upper elastic strip 7 is reliably fixed on the upper pressing edge 21.

[0068] The photovoltaic tile 6 includes a laminate 61 and U-shaped frame strips 62. The U-shaped frame strips 62 are fixed to the edge of the laminate 61 to protect the edge of the laminate 61. Waterproof silicone or sealing tape can be filled between the laminate 61 and the U-shaped frame strips 62 to improve the connection strength between the laminate 61 and the U-shaped frame strips 62, and also to improve the sealing of the edge of the laminate 61. Specifically, the laminate 61 has a rectangular structure, with a U-shaped frame strip 62 installed on each of its four edges. The U-shaped frame strips 62 can be aluminum alloy frame strips, steel alloy frame strips, or composite frame strips. Among them, the composite frame strips are made of polyurethane and fiberglass. The composite frame strips have good insulation, avoiding galvanic corrosion, reducing the risk of potential-induced degradation, and do not require grounding, ensuring the operational stability of the photovoltaic tile 6.

[0069] In one specific embodiment, a lower fixing groove 14 is formed on the side of the lower frame 1 away from the upper frame 2. The lower fixing groove 14 engages with the roof batten 9, and the lower fixing groove 14 is fixedly connected to the batten 9 to ensure that the lower frame 1 is reliably fixed to the roof. Specifically, a locking screw 15 is fixed between the lower fixing groove 14 and the batten 9, preferably a hexagonal self-drilling screw. Of course, the lower fixing groove 14 can also be fixed to the roof runner.

[0071] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
