[0003] The existing photovoltaic tiles have the disadvantages of insufficient wind resistance, poor roof waterproofness, poor installation convenience, high maintenance cost and the like, which are as follows:

Best mode of the present application

[0062] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application is further described in detail below in combination with the drawings and examples.

[0063] As shown in FIGS. 1-22, the present application provides a turnover photovoltaic support, comprising a frame, a top plate 300 and a bottom plate 150, the frame is enclosed 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 arranged below the top plate 300, a second gap 154 is formed on the position of the bottom plate 150 close to the front side wall 110, a turnover mechanism part 600 is arranged on the frame or the top plate 300 or the bottom plate 150, the turnover mechanism part 600 is used to drive the top plate to turn over, at least one mounting position is arranged on the top plate 300, the mounting position is used to mount a photovoltaic power generation assembly.

[0064] As shown in Figure 17, in this embodiment, the turnover mechanism 600 is installed on the side of the left side wall 130 and the right side wall 140 that is close to each other, and the two sides of the top plate 300 are fixedly connected with the two turnover mechanisms 600 respectively. When installing the photovoltaic tile, the top plate 300 is turned over to expose the space at the bottom of the frame body, providing a foothold for the installer or providing installation space for the maintenance ladder 800, thereby improving safety and comfort. It reduces the risk of hidden cracks caused by construction stepping on the glass power generation assembly. 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 greatly improves the installation efficiency.

[0065] The photovoltaic power generation assembly is used to convert light energy into electrical energy. In this embodiment, the photovoltaic power generation assembly is usually composed of surface glass, EVA adhesive film, solar cell, back plate and the like, which belongs to the prior art and will not be described here.

[0066] As shown in Figure 4, in this embodiment, the turnover mechanism 600 is a hinge connection with damping function, so that the top plate 300 can be turned over to any angle. In the above embodiment, the bottom of the first L-shaped groove 232 is fixedly connected with the second wing arm 233 on the side close to the opening thereof, and the second wing arm 233 is fixedly connected with the hinge, so that the top plate 300 can be easily turned over on one side. This design greatly enhances the convenience of initial installation of the top plate and the convenience of later maintenance.

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

[0068] The left side wall 130 is fixedly connected with a first docking portion on the side away from the frame body, and the right side wall 140 is fixedly connected with a second docking portion on the side away from the frame body. The first docking portion and the second docking portion are overlapped with each other.

[0069] As shown in Figures 9-10, the second docking portion is composed of two oppositely arranged second L-shaped wings 141, one end of the two second L-shaped wings 141 is fixedly connected on the right side wall 140, and the other end of the two second L-shaped wings 141 is directed to the side close to each other. The two second L-shaped wings 141 and the right side wall 140 form a chute. The first docking portion is composed of two oppositely arranged first L-shaped wings 131, one end of the two first L-shaped wings 131 is fixedly connected on the left side wall 130, and the other end of the first L-shaped wing 131 is directed to the side away from each other.

[0070] In this embodiment, the first and second abutment parts play a key role in structural waterproofing. The first L-shaped wing plates 131 and the second L-shaped wing plates 141 enclose the first drainage groove 250 in the shape of a square frame, and the two first L-shaped wing plates 131 and the two photovoltaic tiles enclose the second drainage groove 260 in the shape of a square frame. 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 tile and causing damage to the original roof.

[0071] In the above embodiment, two types of waterproof measures are adopted in the overlapping design of the first and second abutment parts. First, when rainwater enters from the connection between the two photovoltaic tiles, the first L-shaped wing plates 131 and the second L-shaped wing plates 141 are tightly attached to the frame, and the water tension can block the rainwater from further penetrating, which is the fourth water-blocking measure. Second, if the rainwater flows along the side walls and into the first drainage groove 250 and the second drainage groove 260, the rainwater will flow out along the three grooves, which is the third water-guiding measure. Through these four blocking and three guiding measures, the best waterproof effect is achieved at the connection between the left and right photovoltaic tiles.

[0072] As shown in FIGS. 5-6, 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 one side close to the rear side wall 120, and 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 extends horizontally towards the front outer plate 111 to form a first support section 113, and is fixedly connected with 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 plate 114 is arranged between the front inner plate 112 and the front outer plate 111. The bottom of the front side wall 110 is provided with a rubber strip mounting groove 116, and a waterproof rubber strip 400 is mounted 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 certain support force for the top plate 300. The bottom of the front side wall 110 is designed with a rubber strip mounting groove 116 for mounting the waterproof rubber strip 400. When the waterproof rubber strip 400 is squeezed, it can shrink into the frame, leaving only a small amount of rubber strip on the aluminum alloy frame. In this way, the photovoltaic tile construction will not cause scratches on the frame due to direct friction between the aluminum alloys. The left and right inner walls provide limiting left and right for the rubber strip, preventing the rubber strip from breaking due to left and right shaking.

[0074] As shown in FIGS. 5-6, the edges of the top plate 300 are enclosed by the front sub-frame 210, the rear sub-frame 220, the left sub-frame 230, and the right sub-frame 240. Two sets of flip mechanism members 600 are arranged, and the left sub-frame 230 and the right sub-frame 240 are respectively fixed to one end of the flip mechanism member 600. The other end of the flip mechanism member 600 is fixed to the frame.

[0075] The front sub-frame 210 comprises a second U-shaped groove 212 for mounting the top plate 300, and a baffle 211. The upper side and the lower side inside the second U-shaped groove 212 are provided with a second glue groove 2121. The baffle 211 is arranged on the side of the second U-shaped groove 212 away from the opening thereof. The top of the baffle 211 extends towards the second U-shaped groove 212 and is fixedly connected with the side wall of the second U-shaped groove 212. The side of the baffle 211 close to the second U-shaped groove 212 is provided with a second clamping strip 2111. The upper part of the front outer plate 111 is provided with a first clamping strip 1111. 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 and the front side wall 110 are fixedly connected by bolts.

[0076] In the embodiment, the first clamping strip 1111 and the second clamping strip 2111 are clamped with each other. The bolt holes reserved on the front side wall 110 and the baffle 211 enable the front side wall 110 and the baffle 211 to be fixed by bolts, thereby achieving the pre-positioning of the top plate 300 and the frame, and effectively enhancing the wind resistance of the photovoltaic tile. In addition, during the later operation and disassembly, the top plate 300 can be turned over only by loosening the bolts, thereby greatly facilitating the maintenance work. The second glue groove 2121 is tooth-shaped on the lower side inside the second U-shaped groove 212 and is rectangular on the upper side inside the second U-shaped groove 212. The second glue groove 2121 increases the friction between the second U-shaped groove 212 and the top plate 300 while ensuring the amount of structural glue.

[0077] As shown in FIG. 9, the left sub-frame 230 and the right sub-frame 230 each comprise a first U-shaped groove 232 and a first fin arm 231. The first fin arm 231 is fixedly connected to the side of the first U-shaped groove 232 away from the opening thereof. The first U-shaped groove 232 is used for mounting the top plate 300. The upper side and the lower side inside the first U-shaped groove 232 are provided with a first glue groove 2321.

[0078] The first fin arm 231 is overlapped on the upper surface of the frame. The top of the left side wall 130 close to the right side wall 140 is provided with a third protruding strip 132. The top of the right side wall 140 close to the left side wall 130 is provided with a fourth protruding strip 142. The first fin arm 231 on the left sub-frame 230 and the right sub-frame 240 respectively abuts against the third protruding strip 132 and the fourth protruding strip 142.
