DETAILED DESCRIPTION

[0017] like Figure 1As shown: a multi-layer photovoltaic solar roof unit 100, including a first layer 1 as a solar photovoltaic panel, a third layer 3 as a bottom layer directly connected to a building, and a second layer 2 between the first layer 1 and the third layer 3, wherein the second layer 2 is a water-conducting and fixing device that simultaneously conducts water and fixes the first layer and the third layer 3. The first layer 1 includes a photovoltaic panel itself 11 and a photovoltaic panel frame 12, wherein the photovoltaic panel frame 12 includes a lower straight edge 121. When forming the multi-layer photovoltaic solar roof unit 100, the lower straight edge 121 is placed on a bracket connection portion 2311, and the predetermined size just matches the size of the bracket connection portion 2311, while the receiving column 122 abuts against the limiting plate 2314. In particular, the lower straight edge 121 extends into the first wedge-shaped groove 23221 and is pressed by the upper wedge wall 23222 of the upper pressing block 232. Therefore, the structure of the bracket arrangement in the present invention plays a role in fixing and clamping the prefabricated solar photovoltaic panel. Fig.14 Also shown is a supporting groove 123 of the photovoltaic panel for accommodating the photovoltaic panel itself.

[0018] Figure 1 and Figure 2 As can be seen in FIG. 1 , the second layer 2 includes at least two U-shaped grooves 21. Figure 4 The opening 211 of the U-shaped groove 21 faces the solar photovoltaic panel.

[0019] Figure 1 It can be seen that the second layer 2 includes a third fixing device 22 for fixing the third layer 3 arranged on the closed bottom 212 of the U-shaped groove 21 and a first fixing device 23 for fixing the solar panel arranged on the first branch 213 and the second branch 214 of the U-shaped groove.

[0020] from Figure 2 and Figure 4 As can be seen in the figure, the cross sections of the first branch 213 and the second branch 214 are respectively C-shaped plates 8 that are far away from each other and extend parallel to each other along the length direction of the solar panel.

[0021] like Figure 2 As shown, the C-shaped plate 8 includes a middle portion 81 , an upper portion 82 above the middle portion, and a lower portion 83 below the middle portion 81 .

[0022] like Figure 1 As shown, the lower portion 83 is connected to the third layer 3 via a third fixing device 22 .

[0023] Figure 1 In the embodiment, the second layer 2 is provided with a collecting device 215 for collecting water from various meteorological phenomena and guiding the collected water to a predetermined place.

[0024] like Figure 3 As shown, a multi-layer photovoltaic solar roof includes the above-mentioned multi-layer photovoltaic solar roof unit 100, wherein two adjacent first branches 213 of the second layer 2 carry the first solar photovoltaic panel, and the two second branches 214 on the outside respectively carry the second solar photovoltaic panel and the third solar photovoltaic panel.

[0025] exist Figure 3 In the embodiment, a plurality of the second layers 2 are connected to be inclined toward one side of the building.

[0026] Figure 3 In the embodiment, the second layers 2 are arranged in parallel with each other and vertically connected to the third layers 3 which are arranged in parallel with each other.

[0027] from Figure 5 , Figure 6 and Figure 7 The components of the first fixing device can be seen, including a bracket 231, an upper pressure block 232 that cooperates with the bracket 231 and is arranged on the upper part of the bracket 231, and a lower bracket 233 that is located at the lower part of the bracket 231 and is connected to the bracket and cooperates with the groove of the upper part 82 of the C-shaped plate 8.

[0028] The bolt 4 connects the lower support block 233 and the bracket 231 from bottom to top, and because the shape of the slider of the lower support block 233 in the groove of the upper part 82 complements each other, it can move along the C-shaped plate 8. It is convenient to adjust the position of the first fixing device 23.

[0029] like Figure 5 , Figure 6 and Figure 7 As shown, the bolts and nuts are connected as a whole through the bracket connecting part 2311, the lower support block connecting part 2331 and the upper pressure block connecting part 2321. At the same time, the bracket matching part 2312 and the upper pressure block matching part 2322 are matched through shape complementarity, and the lower support block matching part 2335 and the groove of the upper part 82 of the C-shaped plate 8 are matched through shape complementarity.

[0030] According to a preferred embodiment of the present invention, a bracket inner cavity 23112 is provided on the bracket 231 to increase the passage for rainwater to pass through and minimize the residual rainwater. Similarly, an upper pressing block inner cavity 2323 is also provided in the upper pressing block 232.

[0031] As can be seen from the accompanying drawings, screws and nuts are arranged through the T-hole 23211, the upper bracket through hole 23111 and the lower bracket through hole 23311 to connect the upper pressing block 232, the lower bracket 233 and the bracket 231 into a whole. Figure 7 In the embodiment, the lower supporting block 233 is further provided with a hollow portion 23312, thereby leaving extra space during installation to allow fluid to pass through.

[0032] It can also be seen from the accompanying drawings that the first wedge-shaped groove 23221 formed by the upper wedge wall 23222 and the lower wedge wall 23223 cooperates with the second wedge-shaped groove 23121 formed by the upper inclined wall 23122 and the lower inclined wall 23123 so that they can limit each other and slide to adjust the installation position.

[0033] It can also be seen in the figure that a nut or a fixing nut can be provided on the boss 23212 so that the bolt 4 can be directly screwed onto the nut, or the bolt 4 can be provided on the boss 23212. In the present invention, the bolt 4 is preferably placed in the boss 23212 first, because the limiting effect of the T-shaped hole 23211 prevents the bolt 4 from rotating when the nut is tightened. Then, the corresponding through holes 23111, 23311 of the bracket 231 and the lower bracket block 233 are passed through the bolt 4 in turn.

[0034] The third connecting device of the present invention includes a supporting block 221, a U-shaped bolt 222 passing through the supporting block through hole 2234 of the supporting block 221, and two branch bolts of the U-shaped bolt 222 passing through the baffle 223 at the bottom of the third layer 3.

Because of the vertical wall 2235, a first gap 2215 is formed after installation. As can be seen from the accompanying drawings, a similar second gap 2335 exists in the first fixing device 23. As a preferred embodiment of the present invention, these gaps 2215, 2335 greatly increase the passage of liquids such as rainwater in the environment, and finally flow into the U-shaped groove 21 of the present invention and flow along the U-shaped groove 21 to a designated position.
