Description

Technical Field

[0001] This invention relates to a building wall component, and more particularly to a building-integrated photovoltaic (BIPV) building wall component. Background Technology

[0002] With the continuous development of photovoltaic technology and the increasing demand for clean energy, the integration of photovoltaics and building-integrated photovoltaics is also expanding. Currently, most photovoltaic systems are connected to building walls using bolts and drilling, which affects the building's structure and has low installation efficiency. Therefore, a new type of photovoltaic building-integrated wall component is needed that is easy to install and does not affect the wall structure. Summary of the Invention

[0003] The purpose of this invention is to provide a building-integrated photovoltaic (BIPV) wall component to solve the above-mentioned technical problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A building-integrated photovoltaic (BIPV) wall component includes a concrete wall, reinforcing bars, a wall protective layer, solar panels, and a solar panel fixing device. The inner side of the concrete wall is filled with reinforcing bars, and the surface of the concrete wall is covered with a wall protective layer. A solar panel is installed at the front end of the wall protective layer and is secured by the solar panel fixing device at the right end.

[0006] Based on the above technical solution, the wall protective layer includes a waterproof wall coating, double-cavity mounting holes, a thermal insulation layer, and a sound insulation board. The outermost side of the concrete wall is sprayed with a waterproof wall coating and has symmetrically distributed double-cavity mounting holes at the four corners. A thermal insulation layer is installed on the inner side of the waterproof wall coating, and a sound insulation board is installed on the inner side of the thermal insulation layer.

[0007] Based on the above technical solution, the solar panel fixing device includes a knob, a first driving pulley, a second driving pulley, a bearing, a belt, a driven pulley, a first bevel gear, a second bevel gear, a gear, a rack, a limiting rod, and a fixing cover. The left end of the knob is equipped with a keyed first driving pulley. The first driving pulley is keyed to the left end of the second driving pulley via a transmission shaft and is fixed to the inner side of the rear end of the solar panel by a bearing hinge. The first and second driving pulleys are connected to driven pulleys symmetrically distributed on both sides via a belt. One end of the driven pulley is fixed by a bearing hinge, and the other end is keyed to the first bevel gear. The first and second bevel gears mesh and achieve a 90-degree change in the transmission direction. The rear end of the second bevel gear is equipped with a keyed gear. Racks are meshed on both sides of the gear. A limiting rod is welded and fixed to the top and bottom of the rack. The limiting rod is embedded and slidably connected to the inside of the through hole on the surface of the fixing cover.

[0008] Compared with the prior art, the present invention has the following advantages: The building wall component of the present invention improves the waterproof, heat insulation and sound insulation capabilities of the building itself through the wall protective layer on the concrete surface, and then fixes the solar panel to the wall surface through the solar panel fixing device in conjunction with the prefabricated double cavity mounting holes. This not only eliminates the need to open holes in the wall surface and damage the wall structure, but also has high disassembly and assembly efficiency and further reduces labor intensity.

[0013] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1-3 As shown, a building-integrated photovoltaic (BIPV) wall component includes a concrete wall 1, reinforcing bars 2, a wall protective layer 3, solar panels 4, and a solar panel fixing device 5. The inner side of the concrete wall 1 is filled with reinforcing bars 2, and the surface of the concrete wall 1 is covered with the wall protective layer 3. A solar panel 4 is installed at the front end of the wall protective layer 3 and is limited and connected by the solar panel fixing device 5 at the right end.

[0015] The wall protective layer 3 includes a waterproof wall coating 6, a double-cavity mounting hole 7, a thermal insulation layer 8, and a sound insulation board 9. The outermost side of the concrete wall 1 is sprayed with a waterproof wall coating 6 and has symmetrically distributed double-cavity mounting holes 7 at the four corners. The thermal insulation layer 8 is installed on the inner side of the waterproof wall coating 6, and the sound insulation board 9 is installed on the inner side of the thermal insulation layer 8.

[0016] The solar panel fixing device 5 includes a knob 10, a first driving pulley 11, a second driving pulley 12, a bearing 13, a belt 14, a driven pulley 15, a first bevel gear 16, a second bevel gear 17, a gear 18, a rack 19, a limiting rod 20, and a fixing cover 21. The knob 10 has a keyed first driving pulley 11 mounted on its left end. The first driving pulley 11 is keyed to the second driving pulley 12 on the left end via a drive shaft and hinged to the inner rear end of the solar panel 4 via a bearing 13. The first driving pulley 11 and the second driving pulley 12 are connected via... The belt 14 is connected to driven pulleys 15 symmetrically distributed on both sides. One end of the driven pulley 15 is hinged and fixed by bearing 13, and the other end is keyed to the first bevel gear 16. The first bevel gear 16 meshes with the second bevel gear 17 and achieves a 90-degree change in the transmission direction. A keyed gear 18 is installed in the middle of the rear end of the second bevel gear 17. A rack 19 meshes with the gear 18 on both sides. A limit rod 20 is welded and fixed at the top and bottom of the rack 19. The limit rod 20 is embedded and slidably connected to the inside of the through hole on the surface of the fixed cover 21.

[0017] The working principle of this invention is as follows: First, the strength of the wall and its waterproof, heat-insulating, and sound-insulating effects are ensured by the steel reinforcement inside the concrete and the waterproof wall covering, insulation layer, and sound insulation board on the surface. Then, the four sets of fixing covers at the rear end of the solar panel are aligned with the double-cavity mounting holes and inserted and connected. Then, by rotating the knob, the first and second driving pulleys are further rotated. The first and second driving pulleys then drive the driven pulleys at both ends to rotate through the belt. At the same time, the driven pulleys rotate, driving the first and second bevel gears to rotate and realizing the change of transmission direction. Then, the second bevel gear drives the rear gear to rotate. During the rotation of the gear, it cooperates with the racks on both sides to convert the rotational motion into the bidirectional horizontal movement of the limiting rod. Then, during the bidirectional movement of the racks, the limiting rod extends along the through hole on the surface of the fixing cover and limits the solar panel in the double-cavity mounting hole to prevent it from falling. Similarly, the reverse operation can retract the limiting rod to realize the disassembly of the solar panel.

[0018] The above description represents a preferred embodiment of the present invention. For those skilled in the art, any changes, modifications, substitutions, and variations made to the implementation methods without departing from the principles and spirit of the present invention, based on the teachings of the present invention, still fall within the protection scope of the present invention.
