[0102] like Figure 1As shown: A multi-layer photovoltaic solar roof unit 100 includes a first layer 1 as a solar photovoltaic panel, a third layer 3 as a bottom layer directly connected to the building, and a second layer 2 between the first layer 1 and the third layer 3. The second layer 2 is a water-guiding and fixing device that simultaneously guides water and fixes the first layer and the third layer 3. The first layer 1 includes the photovoltaic panel itself 11 and a photovoltaic panel frame 12. The photovoltaic panel frame 12 includes a lower straight edge 121. When forming the multi-layer photovoltaic solar roof unit 100, this lower straight edge 121 is placed on a bracket connection part 2311, and the predetermined size matches the size of the bracket connection part 2311, while the support column 122 abuts against the limiting plate 2314. In particular, the lower straight edge 121 extends into the first wedge groove 23221 and is pressed by the upper wedge wall 23222 of the upper pressure block 232. Therefore, the bracket structure in this invention plays a role in fixing and clamping the prefabricated solar photovoltaic panel. Figure 14 The image also shows a support groove 123 for accommodating the photovoltaic panel itself.

[0103] Figure 1 and Figure 2 As can be seen, 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.

[0104] Figure 1 As can be seen, the second layer 2 includes a third fixing device 22 for fixing the third layer 3, which is provided at the closed bottom 212 of the U-shaped groove 21, and a first fixing device 23 for fixing the solar panel, which is provided on the first branch 213 and the second branch 214 of the U-shaped groove.

[0105] from Figure 2 and Figure 4 As can be seen, the cross-sections of the first branch 213 and the second branch 214 are C-shaped plates 8 that are far apart from each other, and they extend parallel to each other along the length direction of the solar panel.

[0106] 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.

[0107] like Figure 1 As shown, the lower part 83 is connected to the third layer 3 via a third fixing device 22.

[0108] Figure 1 In the middle, the second layer 2 is provided with a collection device 215, which is used to collect water from various meteorological phenomena and guide the collected water to a predetermined place.

[0109] like Figure 3 As shown, a multi-layer photovoltaic solar roof includes the aforementioned multi-layer photovoltaic solar roof unit 100. Two adjacent first branches 213 of the second layer 2 carry first solar photovoltaic panels, and two outer second branches 214 respectively carry second and third solar photovoltaic panels.

[0110] exist Figure 3 In the middle, multiple second-layer 2 connections are inclined to one side of the building.

[0111] Figure 3 In the middle, the second layer 2 is arranged parallel to each other and is vertically connected to the third layer 3, which is also arranged parallel to each other.

[0112] 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 disposed on the upper part of the bracket 231, and a lower support block 233 that is located on the lower part of the bracket 231, connected to the bracket, and cooperates with the groove in the upper part 82 of the C-shaped plate 8.

[0113] Bolt 4 connects the lower support block 233 and the bracket 231 together from bottom to top, and because the slider of the lower support block 233 has a complementary shape in the groove of the upper part 82, it can move along the C-shaped plate 8. This facilitates the adjustment of the position of the first fixing device 23.

[0114] like Figure 5 , Figure 6 and Figure 7 As shown, the bolt and nut are connected as one unit 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 mating part 2312 and the upper pressure block mating part 2322 are in complementary shape fit, and the lower support block mating part 2335 and the groove of the upper part 82 of the C-shaped plate 8 are in complementary shape fit.

[0115] According to a preferred embodiment of the present invention, a bracket cavity 23112 is provided on the bracket 231 to increase the passage for rainwater and minimize rainwater residue. Similarly, an upper pressure block cavity 2323 is also provided in the upper pressure block 232.

[0116] As can be seen from the attached diagram, screws and nuts are installed through the T-hole 23211, the upper bracket through hole 23111, and the lower bracket through hole 23311 to connect the upper pressure block 232, the lower bracket 233, and the bracket 231 into a whole. Figure 7 In the middle, the lower support block 233 also has a hollowed-out portion 23312, so as to leave extra space during installation to allow fluid to pass through.

[0117] As can also be seen from the attached figures, the upper wedge wall 23222 and the lower wedge wall 23223 form a first wedge groove 23221 to cooperate with the second wedge 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.

[0118] As can be seen in the figure, a nut or a fixing nut can be set on the boss 23212 so that the bolt 4 can be directly screwed onto the nut. Alternatively, the bolt 4 can be set on the boss 23212. Preferably, the bolt 4 is first placed into the boss 23212. Due to the limiting effect of the T-hole 23211, the bolt 4 will not rotate when the nut is tightened. Then, the corresponding through holes 23111 and 23311 of the bracket 231 and the lower support block 233 are sequentially passed through the bolt 4.

[0119] The third connecting device of the present invention includes a pressure block 221 and a U-bolt 222 passing through a pressure block through hole 2234 of the pressure block 221. Two branch bolts of the U-bolt 222 pass through a baffle 223 at the bottom of the third layer 3, which is preferably a steel beam shown in the figures. The baffle 223 spans the width of the steel beam, thereby securing the second layer 2, preferably a water tank in the present invention, together by tightening the nut.

[0120] Those skilled in the art will readily recognize that the pressure block 221 and the lower support block 233 can be components of the same structure, only requiring a flipping motion during use. Therefore, the pressure block 221 and the lower support block 233 in this invention are interchangeable, reducing the number of parts and facilitating production and installation selection.

[0121] As shown in the attached drawings, a first inclined wall 2231 and a second inclined wall 2232 connected to the root of the first inclined wall 2231 are provided in the support block 221, thus forming a third wedge-shaped groove 2233 to cooperate with the wedge-shaped protrusion 811 on the middle part 81 of the C-shaped plate 8. Because of the presence of the vertical wall 2235, a first gap 2215 is formed after installation. As shown in the attached drawings, a similar second gap 2335 exists in the first fixing device 23. In a preferred embodiment of the invention, these gaps 2215 and 2335 greatly increase the passage of liquids such as rainwater in the environment, and ultimately flow into the U-shaped groove 21 of the invention, flowing along the U-shaped groove 21 to a designated location.

[0122] This invention also provides a method for fixing a second layer and a first layer in a solar power station, comprising the following steps:

[0123] Step 1: Place bracket 231 on the second layer 2, such that the positioning cavity 2315 of bracket 231 complements the upper part 82 of the second layer 2.

[0124] Step 2: Place the lower straight edge 121 of the first layer 1 onto the support platform 2316 of the bracket 231, so that the supporting column 122 of the first layer 1 abuts against the limiting plate 2314.

[0125] Step 3: Insert the bolt 4 into the upper bracket through hole 23111 of the bracket 231;

[0126] Step 4: The screw shank is allowed to pass through the T-shaped hole 23211 of the upper pressure block 232 by horizontal translation, the first wedge groove 23221 of the upper pressure block 232 accommodates the upper inclined wall 23122 and the lower straight edge 121 of the bracket 231, and the lower wedge wall 23223 of the upper pressure block is inserted into the second wedge groove 23121 of the bracket 231;

[0127] Step 5: Move the lower support block 233 from bottom to top, so that the lower support block through hole 23311 of the lower support block 233 passes through the bolt rod of the bolt 4 and the third wedge groove 2233 engages with the wedge protrusion 811 of the upper part 82;

[0128] Step 6: Tighten the nut onto the bolt shank of the bolt 4 to secure it.

[0129] The bracket 231 is provided with a bracket middle cavity 23113 on the opening 211 of the water tank.

[0130] An inner cavity 2323 is provided in the upper pressure block 232.

[0131] In step 5, the lower block inner leg 23314 of the lower block connecting part 2331 of the lower block 233 is opposite to or in contact with the bracket outer leg 231122 of the bracket 231, and the lower block outer leg 23313 is opposite to or in contact with the outer edge of the bracket 231.

[0132] The second layer includes a water tank for collecting and directing rainwater to a predetermined location, and the first layer 1 includes photovoltaic panels.

[0133] It also includes step 7, which sets the product obtained in step 6 onto the third layer 3.

[0134] The third layer 3 includes a building roof 31 and a supporting frame 32 located on the building roof 31. For example... Figure 3 As shown, a frame 33 is also shown, which surrounds the first layer 1 and the second layer 2 along the outer perimeter to form a whole, thus achieving better results both in terms of aesthetics and in terms of ultimately draining water from the photovoltaic panel system.

[0135] According to a preferred embodiment of the present invention, the third layer 3 further includes a load-bearing beam 34 that directly supports the product obtained after step 6.

[0136] Therefore, the power plant 200 is constructed according to the above method. The power plant includes an energy storage device built into the first layer 1.
