Description

Technical Field

[0001] This invention relates to the field of photovoltaic tile technology, and in particular to a flip-type photovoltaic bracket, photovoltaic tile, photovoltaic tile system and its installation method. Background Technology

[0002] Installing photovoltaic (PV) tiles on rooftops converts solar energy into electricity, achieving the goal of generating electricity using solar power. It is a new and promising method of power generation and comprehensive energy utilization, suitable for various locations including residential, commercial, and public buildings. Currently, existing products in this field mainly involve installing PV tiles on rooftops using a conventional, simple frame and glass solar panels, along with connectors and fasteners. The technology involves the installation of the PV tiles, the rational arrangement and spacing of the components, and the application of a waterproof layer. However, existing PV tiles suffer from drawbacks such as insufficient wind resistance, poor roof waterproofing, limited installation convenience, and high maintenance costs, as detailed below:

[0003] 1. Solar photovoltaic tiles are usually arranged closely on the roof, which makes it difficult for installers to step on them during the initial installation and later maintenance. If they step directly on the solar photovoltaic tiles, it can easily cause hidden cracks in the tiles.

[0004] 2. The lack of a stable limiting mechanism between the glass power generation module and the frame results in a significant deficiency in the overall structure's wind resistance performance in strong wind environments.

[0005] 3. The left and right side walls lack an installation limiting mechanism. During on-site installation, close attention must be paid to the precise positioning of each photovoltaic tile. Even slight deviations may result in loose adhesion between the side walls, creating installation error gaps. This can lead to rainwater seeping under the roof during rainy weather, causing serious water leakage problems and increasing maintenance costs.

[0006] 4. Existing photovoltaic tiles are usually integrated structures. If the glass power generation module needs to be replaced during the later operation and maintenance phase, the entire photovoltaic tile needs to be replaced, which will significantly increase the overall maintenance cost.

[0062] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0063] like Figures 1-22 As shown, the present invention provides a flip-type photovoltaic bracket, comprising: a frame, a top plate 300, and a bottom plate 150. The frame is formed by at least a left side wall 130, a right side wall 140, a front side wall 110, and a rear side wall 120. A first gap 160 is formed between the rear side of the top plate 300 and the rear side wall 120. The bottom plate 150 is embedded in the frame and positioned below the top plate 300. A second gap 154 ​​is provided on the bottom plate 150 near the front side wall 110. A flipping mechanism 600 is provided on the frame, the top plate 300, or the bottom plate 150. The flipping mechanism 600 is used to drive the top plate to flip. At least one mounting position is provided on the top plate 300 for mounting photovoltaic power generation modules.

[0064] like Figure 17As shown, in this embodiment, the flipping mechanism 600 is installed on the side of the left wall 130 and the right wall 140 that are close to each other. The top plate 300 is fixedly connected to two flipping mechanisms 600 on both sides. When installing the photovoltaic tiles, the top plate 300 is flipped to expose the space at the bottom of the frame, providing a foothold for installers or installation space for the maintenance ladder 800, thus improving safety and comfort. It also reduces the risk of microcracks caused by stepping on the glass photovoltaic modules during construction. After each product is installed, the top plate 300 is reset. This structure greatly improves the ease of installation of the photovoltaic tiles and significantly increases installation efficiency.

[0065] Photovoltaic power generation modules are used to convert light energy into electrical energy. In this embodiment, photovoltaic power generation modules are typically composed of surface glass, EVA film, solar cells, backsheet, etc., which are existing technologies and will not be described in detail here.

[0066] like Figure 4 As shown, in this embodiment, the flipping mechanism 600 is a hinge connection with damping function, enabling the top plate 300 to flip to any angle. In the above embodiment, a second wing arm 233 is fixedly connected to the bottom of the first C-shaped groove 232 near its opening. The second wing arm 233 is fixedly connected to the hinge, allowing the top plate 300 to easily flip upwards on one side. This design greatly enhances the convenience of initial installation of the top plate and the convenience of subsequent operation and maintenance.

[0067] like Figures 19-20 As shown, a gasket 610 is provided between the tilting mechanism 600 and the left side wall 130 and the right side wall 140. The gasket 610 is a device used in conjunction with the tilting mechanism 600 on the left side wall 130 and the right side wall 140. Its main function is to fill the gaps required by the left and right side walls and the left and right sub-frames due to the mating mechanism, thereby preventing water from flowing into the bottom plate 150 from the gaps, thus reducing the water guiding burden on the bottom plate 150.

[0068] A first mating part is fixedly connected to the side of the left wall 130 away from the frame, and a second mating part is fixedly connected to the side of the right wall 140 away from the frame. The first mating part and the second mating part overlap each other.

[0069] like Figures 9-10 As shown, the second docking portion consists of two opposing second L-shaped wing plates 141. One end of each second L-shaped wing plate 141 is fixedly connected to the right side wall 140, and the other ends of each second L-shaped wing plate 141 face towards each other. The two second L-shaped wing plates 141 and the right side wall 140 form a sliding groove. The first docking portion consists of two opposing first L-shaped wing plates 131. One end of each first L-shaped wing plate 131 is fixedly connected to the left side wall 130, and the other ends of each first L-shaped wing plate 131 face away from each other.

[0070] In this embodiment, the first and second docking portions play a crucial role in structural waterproofing. The first L-shaped wing plate 131 and the second L-shaped wing plate 141 form an approximately U-shaped first drainage channel 250, and the two first L-shaped wing plates 131 and the two photovoltaic tiles enclose an approximately U-shaped second drainage channel 260. Both the first L-shaped wing plates 131 and the second L-shaped wing plates 141 are tightly attached to the frame, effectively preventing rainwater from entering the back of the photovoltaic tiles and causing damage to the original roof.

[0071] In the above embodiments, two types of waterproofing measures are employed in the overlapping design of the first and second docking parts. First, when rainwater enters from the connection point of the two photovoltaic tiles, the first L-shaped wing plate 131 and the second L-shaped wing plate 141 are both tightly attached to the frame, and the surface tension of the water prevents further penetration of the rainwater; this constitutes four water-blocking measures. Second, if rainwater flows along the sidewalls into the first drainage channel 250 and the second drainage channel 260, the rainwater will flow downwards along these three openings; this constitutes three water-guiding measures. Through these four blocking and three guiding measures, the optimal waterproofing effect at the connection point of the left and right photovoltaic tiles is achieved.

[0072] like Figures 5-6 As shown, the front sidewall 110 includes a front outer panel 111 and a front inner panel 112. The front inner panel 112 is located on the side near the rear sidewall 120. The height of the front inner panel 112 is lower than that of the front outer panel 111. The top of the front inner panel 112 extends horizontally towards the front outer panel 111 to form a first support section 113, which is fixedly connected to the front outer panel 111. The bottom of the front inner panel 112 extends away from the front outer panel 111 to form a second support section 115. A connecting partition 114 is provided between the front inner panel 112 and the front outer panel 111. A rubber strip mounting groove 116 is provided at the bottom of the front sidewall 110, and a waterproof rubber strip 400 is installed in the rubber strip mounting groove 116.

[0073] In this embodiment, the design of the second support section 115 can provide stronger structural stability for the photovoltaic tile. The first support section 113 can provide a certain amount of support for the top plate 300. The bottom of the front side wall 110 is designed with a strip mounting groove 116 for installing the waterproof strip 400. When the waterproof strip 400 is squeezed, it can retract into the frame, and the remaining strip will be padded on the aluminum alloy frame. In this way, the frame will not be scratched due to direct friction between the aluminum alloys during the construction of the photovoltaic tile. In addition, the left and right inner walls provide left and right limits for the strip to prevent it from breaking due to left and right shaking.

[0074] like Figures 5-6 As shown, the edge of the top plate 300 is enclosed by a front sub-frame 210, a rear sub-frame 220, a left sub-frame 230, and a right sub-frame 240. The flipping mechanism 600 is provided in two sets. The left sub-frame 230 and the right sub-frame 240 are respectively fixed to one end of the flipping mechanism 600, and the other end of the flipping mechanism 600 is fixed to the frame.

[0075] The front sub-frame 210 includes a second C-shaped groove 212 and a baffle 211. The second C-shaped groove 212 is used to install the top plate 300. Second adhesive grooves 2121 are provided on both the upper and lower sides of the interior of the second C-shaped groove 212. The baffle 211 is located on the side of the second C-shaped groove 212 away from its opening. The top of the baffle 211 extends towards the second C-shaped groove 212 and is fixedly connected to the side wall of the second C-shaped groove 212. A second retaining strip 2111 is provided on the side of the baffle 211 near the second C-shaped groove 212. A first retaining strip 1111 is provided on the upper part of the front outer plate 111. The second retaining strip 2111 is located below the first retaining strip 1111 and engages with it. The baffle 211 is fixedly connected to the front side wall 110 by bolts.

[0076] In this embodiment, the first locking strip 1111 and the second locking strip 2111 are interlocked, and bolt holes are pre-drilled on the front sidewall 110 and the baffle 211, allowing the front sidewall 110 and the baffle 211 to be fixed by bolts. This serves to pre-position the top plate 300 with the frame, thereby effectively enhancing the wind resistance of the photovoltaic tiles. Furthermore, during later maintenance and disassembly, the top plate 300 can be flipped simply by loosening the bolts, greatly simplifying maintenance. The second adhesive groove 2121 is toothed on the lower side inside the second C-shaped groove 212 and rectangular on the upper side inside the second C-shaped groove 212. The second adhesive groove 2121 increases the friction between the second C-shaped groove 212 and the top plate 300 while ensuring the amount of structural adhesive.

[0077] like Figure 9 As shown, both the left sub-frame 230 and the right sub-frame 230 include a first C-shaped groove 232 and a first wing arm 231. The first wing arm 231 is fixedly connected to the side of the first C-shaped groove 232 away from its opening. The first C-shaped groove 232 is used to install the top plate 300. The upper and lower sides of the inside of the first C-shaped groove 232 are provided with first adhesive grooves 2321.

[0078] The first wing arm 231 overlaps the upper surface of the frame. A third protrusion 132 is provided on the top of the left side wall 130 near the right side wall 140, and a fourth protrusion 142 is provided on the top of the right side wall 140 near the left side wall 130. The first wing arm 231 located on the left sub-frame 230 and the right sub-frame 240 abuts against the third protrusion 132 and the fourth protrusion 142 respectively. A first water-blocking strip 2311 is provided on the side of the first wing arm 231 away from the top plate 300. The first water-blocking strip 2311 abuts against the top of the left side wall 130 and the right side wall 140.

[0079] In this embodiment, the left sub-frame 230 and the right sub-frame 240 are respectively mounted on the left and right sides of the top plate 300. Two first wing arms 231 overlap the left side wall 130 and the right side wall 140, forming an effective barrier on both sides of the top plate 300 to prevent a large amount of water from entering the bottom plate 150 area, thus reducing the drainage pressure on the bottom plate 150. The first water-blocking strip 2311 of the first wing arm 231 abuts against the left side wall 130 and the right side wall 140, while the third protrusion 132 and the fourth protrusion 142 abut against the first wing arm 231. The first water-blocking strip 2311, the third protrusion 132, and the fourth protrusion 142 cooperate with each other to enhance the water-blocking effect. This innovative design significantly improves the waterproofing effect of the photovoltaic tiles, ensuring the stable operation of the system under various harsh weather conditions.

[0080] In this embodiment, the first adhesive groove 2321 is toothed on the lower side inside the first incised groove 232 and rectangular on the upper side inside the first incised groove 232. The first adhesive groove 2321 increases the friction between the first incised groove 232 and the top plate 300 while ensuring the amount of structural adhesive.

[0081] like Figure 6 As shown, the rear sub-frame 220 includes a third C-shaped groove 222 and a second water-blocking strip 221. The third C-shaped groove 222 is used to install the top plate 300, and third adhesive grooves 2221 are provided on both the upper and lower sides of the interior of the third C-shaped groove 222. The second water-blocking strip 221 is located at the top of the third C-shaped groove 222 and away from the opening of the third C-shaped groove 222. The second water-blocking strip 221 bends towards the side closer to the opening of the third C-shaped groove 222. The second support section 115 at the bottom of the front inner plate 112 abuts against the top of the third C-shaped groove 222 and is close to the second water-blocking strip 221. The end of the second support section 115 near the second water-blocking strip 221 extends upward to form the third water-blocking strip 1151.

[0082] In this embodiment, the rear sub-frame 220 is assembled behind the top plate 300, adopting an inverted F-shaped design. Used in conjunction with the waterproof strip 400, it forms an effective barrier above the top plate 300, preventing direct wind pressure from causing a large amount of water to enter the base plate 150 area, thus reducing the drainage pressure on the base plate 150. The upper end of the second water-blocking strip 221 has an inwardly curved structure, which, in conjunction with the front sidewall 110 of the upper photovoltaic tile, enhances the water-blocking effect and effectively resists direct wind pressure, preventing rainwater from being directly guided to the rear edge and seeping into the base plate 150. This innovative design significantly improves the waterproof effect of the photovoltaic tile, ensuring stable operation of the system under various harsh weather conditions. The third adhesive groove 2221 is toothed on the lower side inside the third C-shaped groove 222 and rectangular on the upper side inside the third C-shaped groove 222. The third adhesive groove 2221 increases the friction between the third C-shaped groove 222 and the top plate 300 while ensuring the amount of structural adhesive.

[0083] like Figures 1-3 As shown, at least one protrusion 153 is provided on the base plate 150 near the rear side wall 120, and a first mounting hole 1531 is provided on the protrusion 153.

[0084] The windproof buckle 151 is located on the base plate 150 near the rear side wall 120. The windproof buckle 151 is Z-shaped, with the upper part of the windproof buckle 151 higher than the rear side wall 120. The upper end of the windproof buckle 151 passes through the first gap 160 and extends out of the frame. The bottom of the windproof buckle 151 is provided with a groove 1511 that cooperates with the protrusion 153. A second mounting hole corresponding to the first mounting hole 1531 is opened on the groove 1511.

[0085] In this embodiment, screws are used to pass through the second mounting hole of the windproof buckle 151 and the first mounting hole 1531 on the base plate 150 to fix the base plate 150 and the windproof buckle 151 together to the purlin. Through the design of the protrusion 153, rainwater can be prevented from seeping into the back of the base plate through the first mounting hole 1531 at the top of the protrusion 153, which would cause damage to the original roof.

[0086] In this embodiment, the base plate 150 is manufactured using stamping and bending processes. When water flows from the top plate 300 to the base plate 150, the water flows down the base plate 150 and onto the base plate 150 of the next photovoltaic tile, and so on, until the last photovoltaic tile, and then is discharged. Screws pass through the first mounting hole 1531 to fix the base plate 150 to the roof. The protrusion 153 functions after the screws are tightened, effectively preventing water from seeping into the rear surface of the photovoltaic tile along the holes in the base plate 150, thereby preventing water leakage. The protrusion 153 has a semi-circular structure, with the arc end facing the front sidewall 110 and the straight end facing the rear sidewall 120. When it cooperates with the windproof buckle 151, it can effectively limit the installation of the windproof buckle 151, providing convenience for on-site installation.

[0087] In this embodiment, a reinforcing rib 152 is provided on the base plate 150. The protruding part of the reinforcing rib 152 plays a role in guiding water flow, effectively guiding the water flow to the next base plate 150, preventing water from accumulating on the base plate 150, and also plays a role in reinforcing the base plate 150, effectively enhancing the strength of the base plate 150.

[0088] like Figure 18 As shown, the front sidewall 110 is connected to the left sidewall 130 and the right sidewall 140 via connectors 700, and the rear sidewall 120 is also connected to the left sidewall 130 and the right sidewall 140 via connectors 700. In this embodiment, the connector 700 is an L-shaped corner bracket. In use, the L-shaped corner bracket is inserted into the adjacent side panels of the frame and fixed in place. The L-shaped corner bracket significantly enhances the strength of the connection point, making the overall structure more stable. This allows the photovoltaic tiles to withstand greater wind pressure.

[0089] As shown Figure 19 In this embodiment, the inside of the connecting member 700 has several third mounting holes 710 which penetrate the upper and lower side walls of the connecting member 700. The inner side wall of the connecting member 700 has several fifth rib strips 720, and the outer side wall of the connecting member 700 has several first mounting grooves 730. Plugging grooves 170 for plugging the connecting member 700 are provided in the front side wall 110, the rear side wall 120, the left side wall 130 and the right side wall 140. Bolts or screws are used to pass through the frame body and the third mounting holes 710 to fixedly connect the frame body and the L-shaped corner piece. The first mounting grooves 730 can increase the frictional force between the corner piece and the plugging groove 170. The fifth rib strips 720 are in interference fit with the plugging groove 170, reducing the sway between the side frames and improving the connection stability of the frame body.

[0090] The present invention also discloses a photovoltaic tile, which includes a photovoltaic power generation component and a photovoltaic bracket, and the photovoltaic power generation component is fixedly installed at the installation position.

[0091] The present invention also discloses a photovoltaic tile system, which includes photovoltaic tiles. The first docking parts and the second docking parts of adjacent photovoltaic tiles on the left and right are overlapped with each other, and the adjacent photovoltaic tiles on the upper and lower are stacked staggered with each other.

[0092] In this embodiment, the connection mode of adjacent photovoltaic tiles on the left and right is as follows: the second L-shaped wing plate 141 of the photovoltaic tile on the left abuts against the left side wall 130 of the photovoltaic tile on the right, and the first L-shaped wing plate 131 of the photovoltaic tile on the right abuts against the right side wall 140 of the photovoltaic tile on the left. The first L-shaped wing plate 131 and the second L-shaped wing plate 141 enclose a first drainage groove 250 approximately in the shape of a "mouth", and a second drainage groove 260 is enclosed between the two first L-shaped wing plates 131 and the two photovoltaic tiles.

[0093] The connection mode of adjacent photovoltaic tiles on the upper and lower is as follows: the photovoltaic tile on the upper overlaps the photovoltaic tile on the lower. The windproof buckle 151 of the photovoltaic tile on the lower passes through the second gap 154 of the bottom plate 150 of the photovoltaic tile on the upper, and the upper part of the windproof buckle 151 presses the bottom plate 150 of the photovoltaic tile on the upper. The waterproof rubber strip 400 abuts against the top plate. The second support section 115 at the bottom of the front inner plate 112 of the photovoltaic tile on the upper abuts against the top of the third C-shaped groove 222 of the photovoltaic tile on the lower.

[0094] As shown Figures 11-15 And in combination with Figures 21-22As shown, the front waterproof plug 500 is located on the front side of the photovoltaic tile and between two adjacent photovoltaic tiles on the left and right, and the rear waterproof plug 510 is located on the rear side of the photovoltaic tile and between two adjacent photovoltaic tiles on the left and right. The front waterproof plug cover 500 includes a first cover plate 501, a first dovetail insert 502, a first pin 503, a first boss 504, and a first pad 505. The first boss 504 is located on the lower rear side of the first cover plate 501, the first dovetail insert 502 is located on the top of the first cover plate 501, and the first pad 505 is fixedly connected to the bottom of the first cover plate 501. Two first pins 503 are spaced apart along the height direction on the rear side of the first cover plate 501. The first dovetail insert 502 is inserted between the first wing arm 231 and the frame. The two first pins 503 are inserted between the first L-shaped wing plate 131 and the second L-shaped wing plate 141. The first boss 504 separates the first cover plate 501 from the frame, and a drainage port is formed between the first cover plate 501 and the frame.

[0095] In this embodiment, the front waterproof plug 500 serves to prevent wind pressure, provide waterproofing and drainage, and limit the position of the left side wall 130 and the right side wall 140. The front waterproof plug 500 is tightly connected to the left side wall 130 and the right side wall 140 of the adjacent photovoltaic tile via the first pin 503. This design, through the limiting effect of the first pin 503, promotes a tight fit at the joint of the adjacent left side wall 130 and right side wall 140, improving the overall sealing and stability. The front waterproof plug 500 is designed with a drainage outlet, which can quickly guide and drain water accumulated in the inner cavity formed by the overlap of the left side wall 130 and the right side wall 140, namely the water in the first drainage channel 250 and the second drainage channel 260, effectively avoiding potential problems caused by water accumulation. At the same time, the position of the front waterproof plug 500 effectively resists the direct impact of wind pressure, preventing a large amount of water generated by wind pressure from seeping into the first drainage channel 250 and the second drainage channel 260, thereby ensuring the smooth operation of the frame drainage system and avoiding various problems that may be caused by untimely drainage. The lower end of the front waterproof plug 500 is provided with a first pad 505, which can effectively prevent a large amount of water from flowing back from the surface of the left side wall 130 and the right side wall 140 to the rear side wall 120 of the photovoltaic tile.

[0096] The rear waterproof plug cover 510 includes a second cover plate 511 and a second pin 512. Two second pins 512 are spaced apart along the height direction on the rear side of the second cover plate 511. The second pins 512 are inserted between the first L-shaped wing plate 131 and the second L-shaped wing plate 141.

[0097] In this embodiment, the rear waterproof plug 510 serves as a structural water barrier and a limiting element for the adjacent left and right side walls 130 and 140. The rear waterproof plug 510 is tightly connected to the left and right side walls 130 and 140 via a second pin 512. This design, through the limiting effect of the pin, promotes a tight fit at the overlap of the left and right side walls 130 and 140, improving overall sealing and stability. The rear waterproof plug 510 fits tightly against the frame, blocking the seepage path of water that may accumulate in the first and second drainage channels 250 and 260 between the left and right side walls 130 and 140 towards the rear side wall 120 of the photovoltaic tile, fundamentally eliminating potential safety hazards and performance impacts caused by water leakage.

[0098] This invention also discloses a photovoltaic tile installation method for installing a photovoltaic tile system, comprising the following steps:

[0099] a. Overlapping of adjacent photovoltaic tiles on the left and right.

[0100] The first joint on the right side wall of the photovoltaic tile and the second joint on the left side wall of the adjacent photovoltaic tile are connected to each other.

[0101] b. The photovoltaic tiles are stacked alternately on top of each other.

[0102] When stacking photovoltaic tiles in a staggered manner, before installing the rear photovoltaic tiles, lift the top plate 300 of the front photovoltaic tiles at a certain angle so that a gap is formed between the top plate 300 and the front side wall 110 for construction workers to step on or for installing ladder hooks 810.

[0103] like Figure 24 As shown in the image, after the construction workers have installed the first three layers of photovoltaic tiles, it is not possible to install the fourth layer of photovoltaic tiles at the current position. The first layer of photovoltaic tiles needs to be flipped over to create a gap, and then the workers can step on the gap of the first layer to install the fourth layer of photovoltaic tiles.

[0104] Or, such as Figure 25 As shown in the diagram, after the construction workers have installed the first three layers of photovoltaic tiles, it is not possible to install the fourth layer at the current location. The third and first layers of photovoltaic tiles need to be flipped to create a gap. A specially designed maintenance ladder (800) is then installed in this gap. The maintenance ladder 800 has multiple hooks at its rear. The upper hook is attached to the gap in the third layer of photovoltaic tiles, and the lower hook is attached to the gap in the first layer. After securing the maintenance ladder 800, workers can climb it to install the fourth and subsequent layers of photovoltaic tiles. This process is repeated until all photovoltaic tiles are installed.

[0105] c. After all the photovoltaic tiles have been installed, the top plate of all the photovoltaic tiles shall be reset to 300mm.

[0106] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
