[0012] Furthermore, the outer wall of the first profile is fixed with a plurality of first connecting rods extending outward on the side away from the photovoltaic panel. In an adjacent photovoltaic power generation unit, the third profile is formed with a first connecting hole for the insertion of the first connecting rods. Both ends of the first connecting rods are fixed with a first sealing strip that fits against the sidewall of the first connecting hole. The outer wall of the second profile is fixed with a plurality of second connecting rods extending outward on the side away from the photovoltaic panel.

[0014] Furthermore, each of the first to fourth profiles is fixed with a lower support plate and an upper pressure plate, and the mounting plate is placed above the lower support plate. The lower support plate and the mounting plate are fixed together by adhesive.

[0015] Furthermore, the pre-embedded component includes a pre-embedded part and an L-shaped support plate. The pre-embedded part is embedded inside the wall. One end of the L-shaped support plate is provided with an adjusting groove that can be adjusted and connected to the pre-embedded part.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0026] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0027] Reference Figures 1 to 7As shown, a sandwich-structure wall panel with photovoltaic power generation function includes a photovoltaic module 1 and a connecting component 2. The photovoltaic module 1 includes a photovoltaic panel 11 and side profiles 12, with the two side profiles 12 symmetrically arranged on both sides of the photovoltaic panel 11. Each side profile 12 has three hanging slots 1231 arranged linearly along its length, and the hanging slots 1231 are not limited to three. The connecting component 2 includes a mounting plate 25 and a first profile 21 and a third profile 23 respectively fixed on the left and right sides of the mounting plate 25. One end of the first profile 21 and the third profile 23 extends toward the photovoltaic module 1, and the inner walls of the first profile 21 and the third profile 23 are each fixed with a hanging shaft 211 embedded in the hanging slot 1231.

[0028] By attaching the suspension slot 1231 of the edge profile 12 to the suspension shaft 211, a detachable connection between the photovoltaic module 1 and the connecting component 2 is achieved. When the photovoltaic panel 11 is damaged after long-term use, only the photovoltaic module 1 needs to be replaced, without replacing the entire photovoltaic power generation unit (i.e., including the photovoltaic module 1 and the connecting component 2), thereby reducing material waste. Furthermore, the attachment method enables quick installation and removal between the photovoltaic module 1 and the connecting component 2.

[0029] Specifically, the edge profile 12 includes a support portion 121, a first folding plate 122, and a second folding plate 123. The first folding plate 122 is disposed at the lower end of the support portion 121, which is fixed to the lower end of the photovoltaic panel 11. The first folding plate 122 and the support portion 121 form a filling channel 124, and structural adhesive is injected into the filling channel 124 to achieve mutual fixation between the photovoltaic panel 11 and the edge profile 12. The second folding plate 123 is perpendicularly connected to the first folding plate 122, and the second folding plate 123 forms a plurality of hanging slots 1231 connected to the outside. The hanging shaft 211 is engaged in the hanging slots 1231. The engagement between the L-shaped hanging slots 1231 and the hanging shaft 211 enables quick installation and disassembly between the photovoltaic module 1 and the mounting plate 25 connecting component 2. Under the action of gravity, the above engagement prevents the hanging shaft 211 from detaching from the hanging slots 1231.

[0030] The photovoltaic panel 11 is preferably a composite cadmium telluride photovoltaic glass, and the mounting plate 25 is preferably a sandwich panel or a rock wool insulation panel with heat insulation and energy saving properties. The mounting plate 25 is made of the above materials to insulate the wall 4 of the building and ensure that the energy conversion efficiency of the photovoltaic panel 11 is improved and the solar energy loss is reduced.

[0031] The connecting assembly 2 also includes a second profile 22 and a fourth profile 24 respectively fixed to the upper and lower sides of the mounting plate 25. The first to fourth profiles 24 are fixed to the outer periphery of the mounting plate 25 in a clockwise order. The gap between the photovoltaic panel 11 and the mounting plate 25 forms a heat dissipation channel 15. The photovoltaic panel 11 is connected to the second profile 22 through a first ventilation louver 13, and the photovoltaic panel 11 is connected to the fourth profile 24 through a second ventilation louver 14. The first ventilation louver 13 and the second ventilation louver 14 are locked to the second profile 22, the fourth profile 24, and the photovoltaic panel 11 respectively by screws.

[0032] The presence of the heat dissipation channel 15 allows air to enter through the second ventilation louver 14 and exit through the first ventilation louver 13. During the airflow, a certain amount of heat will be carried away, reducing the power loss of circuit components such as the PVC junction box 26 and wires 27 due to excessive temperature. When the air circulates in the heat dissipation channel 15, some of the heat accumulated on the rock wool board will also be carried away, preventing the internal temperature of the cavity space of the first profile 21 to the fourth profile 24 from being too high.

[0033] One of the first profiles 21 to the fourth profile 24 has a wiring space 231 inside. The wiring space 231 is equipped with a PVC outlet box 26 and an electric wire 27 extending from the PVC outlet box 26. This structure ensures that the wiring of the electric wire 27 and the PVC outlet box 26 is built-in, without taking up extra space, and also provides protection and durability for the PVC outlet box 26 and the electric wire 27.

[0034] The first to fourth profiles 24 all extend upward to form limiting side plates 212. The two sides of the photovoltaic panel 11 and the two sides after the photovoltaic panel 11 is connected to the ventilation louvers are limited by the four limiting side plates 212. The photovoltaic panel 11 can slide in the space surrounded by the four limiting side plates 212, thereby locking the hanging slot 1231 with the hanging shaft 211. The first ventilation louver 13 and the second ventilation louver 14 are both provided with screws that are locked to the second profile 22 and the fourth profile 24. The first to fourth profiles 24 are all fixed with a lower support plate 213 and an upper pressure plate 214. The mounting plate 25 is placed above the lower support plate 213, and the lower support plate 213 and the mounting plate 25 are fixed together by adhesive.

[0035] The first profile 21 to the fourth profile 24 are all fixed with a lower support plate 213 and an upper pressure plate 214. The mounting plate 25 is placed above the lower support plate 213. The lower support plate 213 and the mounting plate 25 are fixed together by adhesive. The mounting plate 25 and the first profile 21 to the fourth profile 24 are fixed together by bolts and nuts, thereby ensuring the overall firmness of the connecting assembly 2.

[0036] The outer wall of the first profile 21, away from the photovoltaic panel 11, is fixed with a plurality of first connecting rods 214 extending outward. In adjacent photovoltaic power generation units, the third profile 23 forms a first connecting hole 232 for inserting the first connecting rods 214. Both ends of the first connecting rods 214 are fixed with first sealing strips 2141 that fit against the sidewalls of the first connecting hole 232. Similarly, the outer wall of the second profile 22, away from the photovoltaic panel 11, is fixed with a plurality of second connecting rods 221 extending outward. In adjacent photovoltaic power generation units, the fourth profile 24 forms a second connecting hole 241 for inserting the second connecting rods 221. Both ends of the second connecting rods 221 are fixed with second sealing strips 2211 that fit against the sidewalls of the second connecting hole 241.

[0037] A first sealing strip 215 is fixed to the outer wall of the first profile 21 on the side adjacent to the photovoltaic panel 11. In adjacent photovoltaic power generation units, a third sealing strip 233 is fixed to the outer wall of the third profile 23, which adheres to the first sealing strip 215. Similarly, a second sealing strip 222 is fixed to the outer wall of the second profile 22 on the side adjacent to the photovoltaic panel 11. In adjacent photovoltaic power generation units, a fourth sealing strip 242 is fixed to the outer wall of the fourth profile 24, which adheres to the second sealing strip 222. Through the mutual abutment and sealing relationship of the two sealing strips, the sealing performance on the top, bottom, left, and right sides between photovoltaic power generation units is further improved.

[0038] The above structure achieves a sealed connection between adjacent photovoltaic power generation units on both sides, preventing rainwater from damaging the mounting plate 25, PVC junction box 26, and wires 27 during rainy weather. Furthermore, each photovoltaic power generation unit can be independently disassembled or assembled. When installing photovoltaic power generation units on the outside of the building wall 4, the units are installed piece by piece from bottom to top and from one side to the other; disassembly is performed piece by piece from top to bottom and from one side to the other.

[0039] Reference Figure 6 and Figure 7 As shown, the assembly also includes a pre-embedded component 3, one end of which is embedded in the wall 4, and the other end of which extends upward parallel to the wall surface of the wall 4 to form a hook portion 321. The connecting component 2 also includes a hanger 28, with hangers 28 symmetrically fixed on the left and right sides of the mounting plate 25. The two hangers 28 are respectively fixedly clamped between the mounting plate 25 and the first profile 21 and the third profile 23, and the hangers 28 are hooked onto the hook portion 321. The hook portion 321 is elongated, and the hanger 28 can be adjusted laterally and hung at any position on the hook portion 321, thereby realizing the adjustable spacing between adjacent photovoltaic power generation units, allowing the first connecting rod 214 to be smoothly inserted into the first connecting hole 232, and achieving a sealed fit between adjacent photovoltaic power generation units.

[0040] Specifically, the pre-embedded component 3 includes a pre-embedded part 31 and an L-shaped support plate 32. A notch 41 is opened in the wall 4, and the pre-embedded part 31 is embedded in the bottom surface of the notch 41. One end of the L-shaped support plate 32 is detachably connected to the pre-embedded part 31, and the other end of the L-shaped support plate 32 is parallel to the wall surface of the wall 4 and extends upward to form a hook part 321. The L-shaped support plate 32 is provided with an adjustment groove 322. By adjusting the groove 322, the distance between the hook part 321 and the wall surface can be adjusted, thereby making the distance between the connecting component 2 and the wall surface adjustable, so that the mounting plate 25 fits against the wall surface of the building, which can prevent external wind sources from blowing into the space between the mounting plate 25 and the wall 4 during windy weather, causing the photovoltaic power generation unit to sway.

[0041] In one embodiment, the upper surface of the hook portion 321 is arc-shaped, and correspondingly, the position where the hanger 28 abuts against the hook portion 321 is also arc-shaped, thus allowing the hanger 28 to be smoothly attached to the hook. In another embodiment, the upper surface of the hook portion 321 is flat, and the position where the hanger 28 abuts against the hook portion 321 is also flat. After a screw passes through the hanger 28, it is locked to the hook portion 321, ensuring the firmness of the connection between the hanger 28 and the hook portion 321.

[0042] During installation, one end of the embedded part 31 is first embedded in the wall 4. The embedded component 3 is then fixed to the wall 4 by connecting the screw to the embedded part 31 through the adjusting groove 322. Next, the pre-assembled connecting component 2 and photovoltaic module 1 are assembled by attaching the hanging slot 1231 of the edge profile 12 to the hanging shaft 211. Finally, the entire photovoltaic power generation unit (including photovoltaic module 1 and connecting component 2) is attached to the embedded component 3 by attaching it to the hook part 321 via the hanger 28. The photovoltaic module 1, connecting component 2, and embedded component 3 are detachably connected via a sequential hanging method, making the installation of the photovoltaic power generation unit on the building wall 4 simple and quick.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
