DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0023] As Figures 1-4As shown in the figure, a waterproof structure for the frame of a photovoltaic tile assembly includes an aluminum alloy frame 1 installed at the edge of a laminate 4. A plurality of laminates 4 are kept flush, and the aluminum alloy frames 1 are arranged opposite to each other accordingly. A waterproof support mechanism 2 is provided between the aluminum alloy frames 1 of adjacent laminates 4 or between the aluminum alloy frame 1 and a flat tile 41. On the one hand, the waterproof support mechanism 2 supports the aluminum alloy frame 1, and on the other hand, it completely seals the gap therebetween to prevent rainwater leakage. Flexible sealing strips 3 are fixedly connected to the aluminum alloy frames 1 respectively. A first waterproof component 5 is provided between the aluminum alloy frame 1 of adjacent laminates 4 and the sealing strip 3, and upper and lower adjacent second waterproof components 6 and third waterproof components 7 are provided between the sealing strips 3 of adjacent laminates 4. The first waterproof component 5, the second waterproof component 6, and the third waterproof component 7 are arranged in sequence from top to bottom to achieve multi-layer waterproofing.

[0024] Specifically, the aluminum alloy frame 1 is made of aluminum alloy material and is coated on the circumferential outer side of the laminate 4. It specifically includes a main frame body 11. A sealing groove 12 for inserting the laminate 4 is opened on the side of the main frame body 11. A filling groove 13 is opened on one side of the inner side of the sealing groove 12. A sealing glue 14 is filled between the sealing groove 12 and the filling groove 13 and the edge of the laminate 4 for blocking. A cavity extending along the axial direction is provided inside the main frame body 11. This cavity structure ensures the structural strength of the main frame body 11, and a groove is also provided at its lower end to facilitate the installation and fixation of threaded parts.

[0025] In-depth, the first waterproof component 5 includes a buckle cover 51 that fits and covers between the upper ends of the aluminum alloy frames 1. The buckle cover 51 blocks the upward-facing seam between adjacent aluminum alloy frames 1, further improving the waterproof effect. First protruding structures 53 that extend downward and cover the top edge of the aluminum alloy frame 1 are respectively provided at both ends of the buckle cover 51. The first protruding structure 53 at the edge of the end of the buckle cover 51 is a water drip line. A buckle plate 52 that is inserted between two adjacent sealing strips 3 is provided at the lower end of the buckle cover 51. A second protruding structure 54 that extends toward one side and engages with the inner side of the adjacent sealing strip 3 is provided at the lower end of the buckle plate 52. The buckle cover 51 and the buckle plate 52 are integrally formed and have a T-shaped cross-section. During installation, first, the buckle plate 52 and the buckle cover 51 are clamped to one of the aluminum alloy frames 1, and then the aluminum alloy frames 1 are relatively moved closer. The inner sealing strip 3 exerts a squeezing force on the buckle plate 52. Compared with the conventional extrusion sealing structure in the prior art, the buckle cover 51 directly blocks the upward-facing seam, and the first protruding structure 53 on its side forms a water drip line to guide rainwater to slide outside the aluminum alloy frame 1. The second protruding structure 54 at the lower end of the buckle plate 52 makes the side of the buckle plate 52 form a limiting groove body, which is convenient for clamping and limiting the sealing strip 3.

[0026] Furthermore, the second waterproof component 6 is integrally of an elastic structure, specifically including a first waterproof strip 61 disposed on the opposite side of adjacent sealing strips 3. The first waterproof strip 61 is arranged between the upper parts of the upward-facing seams of adjacent aluminum profile frames 1. Since the first waterproof strips 61 are arranged in pairs and the two first waterproof strips 61 in a pair are oppositely arranged, after the photovoltaic module is installed, the two opposite first waterproof strips 61 can be mutually attached for waterproof sealing or attached and pressed against the clamping plate 52 to achieve sealing; the first waterproof strip 61 has an internal collision cavity, and the first waterproof strips 61 of adjacent sealing strips 3 are mutually attached and extruded or attached and extruded against the clamping plate 52. When the aluminum profile frames 1 approach each other, the first waterproof strips 61 are mutually extruded and deformed to completely block their gaps. The collision cavity enhances the deformation ability of the first waterproof strip 61, the deformation increases the contact area, and the deformation improves the adhesion of the opposite surfaces of the first waterproof strip 61 in contact with each other, or the adhesion of the first waterproof strip 61 in contact with the clamping plate 52, thereby improving the sealing effect. The sealing strip 3 is usually made of rubber material, so the first waterproof strip 61 on the sealing strip 3 and the clamping plate 52 have a large frictional force, which can prevent the buckling cover 51 from falling off.

[0027] A fitting cavity is formed between the buckling cover 51 and the second convex structure 54. The cooperation between the fitting cavity and the first waterproof strip 61, for example, the length of the side frame of the clamping plate 52 in the height direction (the distance between the buckling cover 51 and the second convex structure 54) is the same as the length of the strict frame of the first waterproof strip 61 in the height direction. During the installation process, the fitting cavity can be clamped at the first waterproof boss 61 for temporary fixation. After the photovoltaic module is installed, this place is extruded. When the first waterproof strip 61 is extruded, the first waterproof strip 61 can be closely attached to the cavity wall of the fitting cavity, thereby improving the waterproof performance.

[0028] Furthermore, the third waterproof component 7 includes a second waterproof strip 71 disposed on the opposite side of the sealing strip 3. The second waterproof strip 71 is located between the lower parts of the upward-facing seams of adjacent aluminum profile frames 1. The second waterproof strip 71 has a water guide groove extending along the axial direction and opening upward, and the second waterproof strips 71 of adjacent sealing strips 3 are mutually attached and extruded; the second waterproof strip 71 is located below the first waterproof strip 61. When rainwater leaks, the second waterproof strip 71 further seals it, and its water guide groove can guide the rainwater out to avoid direct falling.

[0029] As Figure 2As shown in the figure, when rainwater slides down along the gap between the first waterproof component 5 and the aluminum profile frame 1 to the top of the upward-facing joint of the adjacent aluminum profile frames 1, the first waterproof strips 61 are pressed against each other or against the side of the buckle plate 52 to seal the upward-facing joint and prevent leakage. If the rainwater still leaks along the gap between the first waterproof strips 61 or between the first waterproof strips 61 and the buckle plate 52, the second waterproof strips 71 between the lower ends of the upward-facing joints are pressed against each other to close. The water guide grooves facing upward of the second waterproof strips 71 guide the rainwater to drain along the length direction of the second waterproof strips 71, preventing water leakage and seepage between adjacent components. The length direction of the second waterproof strips 71 is consistent with the roof slope direction, that is, the frame where the second waterproof strips 71 are installed is consistent with the roof slope direction, thereby realizing water diversion and drainage along the roof slope direction.

[0030] In addition, the side of the aluminum profile frame 1 is provided with a first locking groove 15 and a second locking groove 16, which are arranged adjacent to each other vertically. In addition to allowing the sealing strip 3 to be inserted and fixed, the first locking groove 15 and the second locking groove 16 can also meet the assembly connection requirements of the buckle and threaded parts. The double rubber strip and double groove structure of the aluminum profile frame 1 can adapt to various rubber strip forms and at the same time match the insertion and cooperation of non-standard profile parts.

[0031] At the same time, the waterproof support mechanism 2 includes a fourth waterproof component 8 arranged between the aluminum profile frame 1 and the upper edge of the flat tile 41, and a fifth waterproof component 9 is arranged between the aluminum profile frame 1 and the lower edge of the flat tile 41. The fourth waterproof component 8 and the fifth waterproof component 9 support the flat tile 41 in contact to ensure the sealing and waterproof effect at their joints. The aluminum profile frame 1 can adjust the matching aluminum profile fittings to adapt to various tile connections or non-standard position treatments.

[0032] Visibly, the upper edge of the flat tile 41 is grooved. The fourth waterproof component 8 includes a first aluminum profile fitting 81 lapped on the upper edge of the flat tile 41, and the first aluminum profile fitting 81 and the groove body are horizontally limited by a buckle. The first aluminum profile fitting 81 has a first hook 82 inserted into the first locking groove 15 and the second locking groove 16. The first aluminum profile fitting 81 has a first cover 83 covering the upper end of the aluminum profile frame 1. The first hook 82 and the first cover 83 form a clamping groove structure to cooperate with the aluminum profile frame 1. A drip line is provided at the front end of the first cover 83, and the drip line guides the rainwater to slide to the outside of the aluminum profile frame 1 relative to the upper edge of the aluminum profile frame 1. A threaded part is connected between the first aluminum profile fitting 81 and the aluminum profile frame 1 for further fastening treatment.

[0033] Obviously, the fifth waterproof component 9 includes a second aluminum profile accessory 91 overlapped at the lower edge of the flat tile 41, and the lower edge of the flat tile 41 is grooved and engaged with the buckle on the side of the aluminum profile frame 1. The second aluminum profile accessory 91 has a second hook 92 inserted into the first locking groove 15 and the second locking groove 16, and the second aluminum profile accessory 91 has a second buckle cover 93 covering the upper end of the aluminum profile frame 1, and a drip line is set at the front end of the second buckle cover 93. The second buckle cover 93 and the drip line can prevent rainwater from leaking along the gap of the aluminum profile frame 1.

[0034] Preferably, the sealing strip 3 has a locking strip 31 respectively inserted into the first locking groove 15 and the second locking groove 16. The locking strip 31 has an undercut that is engaged with the inner side of the first locking groove 15 and the second locking groove 16. Since the sealing strip 3 is made of elastic material as a whole, the locking strip 31 can be directly pressed and inserted to complete the assembly. Compared with conventional hard contact, the elastic sealing strip 3 can prevent the glass component from being damaged in the case of thermal expansion and contraction.

[0035] To sum up, the principle of this embodiment is that the edge of the laminate 4 is covered by the aluminum profile frame 1, and a sealing strip 3 is arranged between the aluminum profile frames 1 of adjacent laminates 4 for fitting and clamping, and a first waterproof component 5, a second waterproof component 6 and a third waterproof component 7 are arranged in sequence from top to bottom between the aluminum profile frame 1 and the sealing strip 3 for multiple sealing and waterproofing to ensure the sealing and waterproofing effect at the junction of the photovoltaic tiles.
