Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic tiles, and in particular to a flip-type photovoltaic bracket, a photovoltaic tile, a photovoltaic tile system and an installation method thereof. Background Art

[0002] Photovoltaic tiles are laid on the roof to convert solar energy into electrical energy, so as to achieve the purpose of using light energy to generate electricity. It is a new way of power generation and comprehensive energy utilization with broad development prospects, suitable for a variety of places such as civil buildings, commercial buildings, and public buildings. The current products on the market are mainly used in this field through the combination of conventional simple frames and glass solar panels, and are installed on the roof in combination with connectors and fixings. The technology is the installation of photovoltaic tiles, the reasonable setting of component arrangement intervals, and the processing and setting of waterproof layers. Existing photovoltaic tiles have the disadvantages of insufficient wind resistance, poor roof waterproofing, weak installation convenience, and high subsequent maintenance costs, as follows:

[0003] 1. Photovoltaic tiles are usually arranged closely on the roof, which makes it difficult for installers to step on them during the early installation and later maintenance. If they step directly on the photovoltaic tiles, it is easy to cause the risk of hidden cracks in the photovoltaic tiles.

[0004] 2. There is a lack of a stable limiting mechanism between the glass power generation components and the frame, resulting in significantly insufficient wind resistance of the overall structure in strong wind environments.

[0005] 3. The left and right side walls lack installation limit mechanisms. During on-site installation, close attention must be paid to the precise positioning of each photovoltaic tile. A slight deviation may result in a loose fit between the side walls and an installation error gap, which in turn causes rainwater to penetrate under the roof on rainy days, causing serious leakage problems and increasing maintenance costs.

[0006] 4. Existing photovoltaic tiles are usually an integrated structure. In the later operation and maintenance stage, if the glass power generation components need to be replaced, the entire photovoltaic tile needs to be replaced, which will significantly increase the overall maintenance cost.

Detailed implementation manners

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

[0063] As Figures 1 to 22 shown, the present invention provides a flip-type photovoltaic bracket, including: a frame body, a top plate 300 and a bottom plate 150. The frame body is at least enclosed by 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 surface of the top plate 300 and the rear side wall 120. The bottom plate 150 is embedded in the frame body and is disposed below the top plate 300. A second gap 154 is formed at a position of the bottom plate 150 close to the front side wall 110. A flipping mechanism member 600 is disposed on the frame body or the top plate 300 or the bottom plate 150. The flipping mechanism member 600 is used to drive the top plate to flip. At least one installation position is provided on the top plate 300, and the installation position is used to install a photovoltaic power generation component.

[0064] As Fig.17As shown, in this embodiment, the flipping member 600 is installed on the side where the left side wall 130 and the right side wall 140 are close to each other. Both sides of the top plate 300 are fixedly connected to the two flipping members 600 respectively. When installing the photovoltaic tile, the top plate 300 is flipped to expose the space at the bottom of the frame, providing a foothold for installers or an installation space for the maintenance ladder 800, improving safety and comfort. It reduces the risk of hidden cracks caused by the trampling of the glass power generation components during construction. After the installation of a single product is completed, the top plate 300 is reset. This structure greatly improves the installation convenience of the photovoltaic tile and significantly improves the installation efficiency.

[0065] The photovoltaic power generation component is used to convert light energy into electrical energy. In this embodiment, the photovoltaic power generation component usually consists of surface glass, EVA film, solar cell chips, backplane, etc., which belongs to the prior art and will not be elaborated here.

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

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

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

[0069] As Figures 9-10 shown, the second docking portion consists of two relatively arranged second L-shaped wing plates 141. One end of the two second L-shaped wing plates 141 is fixedly connected to the right side wall 140, and the other ends of the two second L-shaped wing plates 141 face the side close to each other. The two second L-shaped wing plates 141 and the right side wall 140 enclose a chute. The first docking portion consists of two relatively arranged first L-shaped wing plates 131. One end of the two first L-shaped wing plates 131 is fixedly connected to the left side wall 130, and the other end of the first L-shaped wing plate 131 faces the side away from each other.

[0070] In this embodiment, the first docking portion and the second docking portion play a key role in structural waterproofing. The first L-shaped wing plate 131 and the second L-shaped wing plate 141 form a first drainage groove 250 that is approximately in the shape of a U-shaped truncated ...

[0071] In the above embodiment, two types of waterproof measures are adopted in the overlap design of the first docking part and the second docking part. First, when rainwater enters from the connection between 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 tension of the water can prevent the rainwater from further penetrating. This is the four water blocking measures. Second, if the rainwater flows along the side wall and flows into the first drainage groove 250 and the second drainage groove 260, the rainwater will flow downward along these three grooves. This is the three water diversion measures. Through these four blocking and three dredging measures, the best waterproof effect at the connection between the left and right photovoltaic tiles is achieved.

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

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

[0074] like Figures 5-6 As shown, the edge of the top plate 300 is surrounded by a front sub-frame 210, a rear sub-frame 220, a left sub-frame 230 and a right sub-frame 240, and the flip mechanism component 600 is provided with two groups, the left sub-frame 230 and the right sub-frame 240 are respectively fixed on one end of the flip mechanism component 600, and the other end of the flip mechanism component 600 is fixed on the frame body.

[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 for installing the top plate 300. Second glue grooves 2121 are provided on both the upper side and the lower side inside the second C-shaped groove 212. The baffle 211 is arranged 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 clamping strip 2111 is provided on the side of the baffle 211 close to the second C-shaped groove 212. A first clamping strip 1111 is provided on the upper part of the front outer plate 111. The second clamping strip 2111 is located below the first clamping strip 1111 and is clamped with the first clamping strip 1111. The baffle 211 is fixedly connected to the front side wall 110 by bolts.

[0076] In this embodiment, the first clamping strip 1111 and the second clamping strip 2111 are clamped with each other, and bolt holes are reserved on the front side wall 110 and the baffle 211, so that the front side wall 110 and the baffle 211 can be fixed by bolts, playing a role in pre-positioning the top plate 300 and the frame body, thereby effectively enhancing the wind uplift resistance performance of the photovoltaic tile. At the same time, during later operation and maintenance and disassembly, only need to loosen the bolts to flip the top plate 300, which brings great convenience to the maintenance work. The second glue grooves 2121 are in a tooth shape on the lower side inside the second C-shaped groove 212 and in a rectangular shape on the upper side inside the second C-shaped groove 212. The second glue grooves 2121 increase the friction between the second C-shaped groove 212 and the top plate 300 while ensuring the amount of structural glue.

[0077] As Fig. 9 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 for installing the top plate 300. First glue grooves 2321 are provided on both the upper side and the lower side inside the first C-shaped groove 232.

[0078] The first wing arm 231 overlaps on the upper surface of the frame body. A third convex strip 132 is provided on the top of the left side wall 130 close to the right side wall 140. A fourth convex strip 142 is provided on the top of the right side wall 140 close to the left side wall 130. The first wing arms 231 on the left sub-frame 230 and the right sub-frame 240 are respectively abutted against the third convex strip 132 and the fourth convex strip 142. 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 tops of the left side wall 130 and the right side wall 140.

[0079] In this embodiment, the left auxiliary frame 230 and the right auxiliary frame 240 are respectively assembled on the left and right sides of the top plate 300. The two first wing arms 231 are respectively lapped on the left side wall 130 and the right side wall 140, forming an effective barrier partition on the left and right sides of the top plate 300 to prevent a large amount of water flow from entering the bottom plate 150 area, 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, and the third rib 132 and the fourth rib 142 abut against the first wing arm 231. The first water blocking strip 2311, the third rib 132 and the fourth rib 142 cooperate with each other to enhance the water blocking effect. This innovative design significantly improves the waterproof effect of the photovoltaic tile and ensures the stable operation of the system under various harsh weather conditions.

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

[0081] As Figure 6 shown, the rear auxiliary 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 glue grooves 2221 are provided on both the upper side and the lower side inside the third C-shaped groove 222. The second water blocking strip 221 is arranged at the top of the third C-shaped groove 222 and on the side far from the opening of the third C-shaped groove 222, and the second water blocking strip 221 is bent towards the side close 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. One end of the second support section 115 close to the second water blocking strip 221 extends upward to form a third water blocking strip 1151.

[0082] In this embodiment, the rear auxiliary frame 220 is assembled behind the top plate 300 and adopts an inverted F-shaped design. When used in conjunction with the waterproof rubber strip 400, it forms an effective barrier above the top plate 300 to prevent a large amount of water flow from entering the bottom plate 150 area due to the direct blowing of wind pressure, reducing the drainage pressure on the bottom plate 150. The upper end of the second water blocking strip 221 is provided with an inward bending structure, which cooperates with the front side wall 110 of the upper-layer photovoltaic tile to enhance the water blocking effect and can also effectively resist the direct blowing of strong wind pressure, preventing rainwater from being directly guided to the rear edge and seeping into the bottom plate 150. This innovative design significantly improves the waterproof effect of the photovoltaic tile and ensures the stable operation of the system under various harsh weather conditions. The third glue groove 2221 is tooth-shaped 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 glue groove 2221 increases the friction between the third C-shaped groove 222 and the top plate 300 while ensuring the amount of structural glue.

[0083] As Figures 1 to 3 As shown, at least one convex bump 153 is disposed at a position of the bottom plate 150 close to the rear side wall 120 , and a first mounting hole 1531 is formed on the convex bump 153 .

[0084] The bottom plate 150 of the windproof buckle 151 is close to the rear side wall 120, and the windproof buckle 151 is Z-shaped. The upper part of the windproof buckle 151 is higher than the rear side wall 120, and the upper end of the windproof buckle 151 passes through the first gap 160 and extends outside the frame. A groove 1511 matching the convex bump 153 is provided at the bottom of the windproof buckle 151, and 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 on the purlin. The design of the convex bump 153 can prevent rainwater from penetrating into the back of the base plate through the first mounting hole 1531 on the top of the convex bump 153, causing damage to the original roof.

[0086] In this embodiment, the bottom plate 150 is stamped and bent. When water flows from the top plate 300 to the bottom plate 150, the water will flow down along the bottom plate 150 and flow to the bottom plate 150 of the next photovoltaic tile, and so on, until the last photovoltaic tile, and then be discharged. The screw passes through the first mounting hole 1531 to fix the bottom plate 150 on the roof. The convex bump 153 works after the screw is tightened, effectively preventing the water from penetrating into the rear surface of the photovoltaic tile along the hole of the bottom plate 150, thereby preventing the occurrence of water leakage; the convex bump 153 is a semicircular structure, with the arc end facing the front side wall 110 and the straight end facing the rear side wall 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, reinforcing ribs 152 are provided on the bottom plate 150. The raised portion of the reinforcing ribs 152 serves to guide water, effectively guiding the water flow to the next bottom plate 150 to prevent water from accumulating on the bottom plate 150, and serves to stiffen the bottom plate 150, effectively enhancing the strength of the bottom plate 150.

[0088] like Fig.18 As shown, the front side wall 110 is connected to the left side wall 130 and the right side wall 140 by a connector 700, and the rear side wall 120 is connected to the left side wall 130 and the right side wall 140 by a connector 700. In this embodiment, the connector 700 is an L-shaped corner bracket. When in use, the L-shaped corner bracket is inserted into the adjacent side plate of the frame and fixed. The L-shaped corner bracket can significantly enhance the strength of the connection point, making the overall structure more stable, so that the photovoltaic tile can withstand greater wind pressure.

[0089] like Fig.19 As shown in the figure, in this embodiment, the inside of the connecting member 700 has a number of third mounting holes 710 that penetrate through the upper and lower side walls of the connecting member 700. The inner side wall of the connecting member 700 has a number of fifth ridges 720, and the outer side wall of the connecting member 700 has a number of 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 joint. The first mounting grooves 730 can increase the friction between the corner joint and the plugging groove 170. The fifth ridges 720 are in interference fit with the plugging groove 170, reducing the shaking between the 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 support, 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 in an interleaved manner.

[0092] In this embodiment, the connection method 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 that is approximately in the shape of a "square", 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 method 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, and 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 local photovoltaic tile.

[0094] As Figures 11 to 15 and in combination with Figures 21-22As shown, the front waterproof plug cover 500 is arranged on the front side of the photovoltaic tile and between two adjacent photovoltaic tiles on the left and right, and the rear waterproof plug cover 510 is arranged 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 plug 502, a first latch 503, a first boss 504 and a first cushion block 505. The first boss 504 is arranged at the lower rear side of the first cover plate 501, the first dovetail plug 502 is arranged on the top of the first cover plate 501, and the first cushion block 505 is fixedly connected to the bottom of the first cover plate 501. Two first latches 503 are arranged at intervals along the height direction of the rear side of the first cover plate 501. The first dovetail plug 502 is inserted between the first wing arm 231 and the frame, and the two first latches 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 hydrophobic port is formed between the first cover plate 501 and the frame.

[0095] In this embodiment, the front waterproof plug cover 500 plays the role of structural wind pressure protection, waterproofing, hydrophobicity, and limiting the left side wall 130 and the right side wall 140. The front waterproof plug cover 500 is closely connected to the left side wall 130 and the right side wall 140 of the adjacent photovoltaic tile through the first latch 503. This design promotes the close fit of the overlapping parts of the left and right adjacent left and right walls 130 and 140 through the limiting effect of the first latch 503, thereby improving the overall sealing and stability. The front waterproof plug cover 500 is designed with a drainage port, which can quickly guide and discharge the water accumulated in the inner cavity formed by the overlap of the left side wall 130 and the right side wall 140, that is, the water in the first drainage groove 250 and the second drainage groove 260, effectively avoiding potential problems caused by water accumulation; at the same time, the front waterproof plug cover 500 is effectively protected from direct invasion of wind pressure, preventing a large amount of water generated by wind pressure from penetrating into the first drainage groove 250 and the second drainage groove 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 cover 500 is provided with a first cushion block 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 latch 512 . Two second latches 512 are spaced apart on the rear side of the second cover plate 511 along its height direction. The second latch 512 is 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 cover 510 plays a role in structural water blocking and limiting the left and right adjacent walls 130 and 140. The rear waterproof plug cover 510 is closely connected to the left and right walls 130 and 140 through the second latch 512. This design promotes the close fit of the left and right walls 130 and 140 at the overlap through the limiting effect of the latch, and improves the overall sealing and stability. The rear waterproof plug cover 510 fits tightly with the frame, blocking the path of the accumulated water that may accumulate in the first drainage groove 250 and the second drainage groove 260 between the left and right walls 130 and 140 to penetrate into the rear wall 120 of the photovoltaic tile, fundamentally eliminating the potential safety hazards and performance impacts caused by water leakage.

[0098] The present invention also discloses a photovoltaic tile installation method for installing a photovoltaic tile system, comprising the following process:

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

[0100] The first butt joint portion of the right side wall of the photovoltaic tile and the second butt joint portion of the left side wall of the adjacent photovoltaic tile are overlapped with each other.

[0101] b. The upper and lower adjacent photovoltaic tiles are stacked alternately.

[0102] When the photovoltaic tiles are stacked in an offset manner, before installing the rear photovoltaic tiles, the top plate 300 of the front photovoltaic tiles is lifted 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 stand or for installing ladder hooks 810.

[0103] like Fig.24 As shown in , after the construction workers have completed the construction of the first three layers of photovoltaic tiles, the fourth layer of photovoltaic tiles cannot be constructed at the current position. The first layer of photovoltaic tiles needs to be flipped over to form a gap, and then the fourth layer of photovoltaic tiles can be constructed by stepping on the gap of the first layer.

[0104] Or, if Fig.25 As shown in , after the construction workers have completed the construction of the first three layers of photovoltaic tiles, the fourth layer of photovoltaic tiles cannot be constructed at the current position. The third and first layers of photovoltaic tiles need to be flipped over to form a gap, and then a ladder is installed at the gap. The ladder is a special maintenance ladder 800, and the rear end of the maintenance ladder 800 is provided with multiple hooks. The upper hook is hung in the gap of the third layer of photovoltaic tiles, and the lower hook is hung in the gap of the first layer of photovoltaic tiles. After the maintenance ladder 800 is fixed, the maintenance ladder 800 can be climbed to construct the fourth layer and above layers of photovoltaic tiles. By analogy, the construction of all photovoltaic tiles is realized.

[0105] c. After all the photovoltaic tiles are constructed, the top panels 300 of all the photovoltaic tiles are reset.

[0106] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
