Technical Field

[0001] This invention relates to the field of curtain wall technology, specifically to a photovoltaic wall panel and a multi-layered point-type photovoltaic curtain wall system. Background Technology

[0002] Currently, in order to meet the aesthetic function of buildings, photovoltaic systems are installed on buildings to achieve a good integration of photovoltaics and buildings. This can not only convert light energy into electrical energy, but also fully reflect the concept of environmentally friendly green buildings.

[0003] Current photovoltaic wall panels, as described in patent CN215670492U, include photovoltaic modules and aluminum profiles. The photovoltaic module includes a photovoltaic panel, a honeycomb panel, an insulation layer, and a protective layer. A first adhesive layer is disposed on the top of the photovoltaic panel. The side of the first adhesive layer away from the photovoltaic panel is bonded to one side of the honeycomb panel. The side of the honeycomb panel away from the first adhesive layer is bonded to one side of a second adhesive layer. The side of the second adhesive layer away from the honeycomb panel is bonded to one side of the insulation layer. The side of the insulation layer away from the second adhesive layer is bonded to one side of a third adhesive layer. The side of the third adhesive layer away from the insulation layer is bonded to one side of the protective layer. The protective layer is folded at 90° on all four sides on the side away from the third adhesive layer.

[0004] Regarding the aforementioned technologies, the inventors believe that shading of photovoltaic panels will cause the entire photovoltaic wall panel to lose its light transmittance, resulting in the inability to meet subsequent indoor lighting needs. Summary of the Invention

The top and bottom sides of the fixing frame each have wire holes adapted to the cable. Both ends of the cable pass through the two sets of wire holes respectively, and both ends of the cable are fixedly connected to a compatible male plug and female socket. The other end of each set of U-shaped fixing back plates is fixedly connected to a rotating shaft. Each set of rotating shafts is rotatably connected to the inner wall of the fixing frame. A worm gear is fixedly connected to the outer side of each set of rotating shafts. A worm is meshed with one side of each set of worm gears. The bottom of the worm is rotatably connected to the inner wall of the fixing frame. A first bevel gear is fixedly connected to the outer side of the worm. A second bevel gear is meshed with the bottom of the first bevel gear. An adjusting shaft is fixedly connected to the end of the second bevel gear away from the worm. The adjusting shaft is rotatably connected to the fixing frame.

[0007] Optionally, each of the four inner corners of the inner transparent glass plate is provided with a fixing bolt, and each set of fixing bolts is threadedly connected to the fixing frame.

[0008] Optionally, a rectangular groove is provided at the end of the adjusting shaft away from the second bevel gear, and a matching rectangular plug is inserted into the rectangular groove. A rocker is fixedly connected to the end of the rectangular plug away from the adjusting shaft.

[0009] Optionally, the top of the fixed frame is provided with a transmission hole adapted to the worm gear, the bottom of the worm gear extends to the bottom wall of the fixed frame, and both ends of the worm gear are provided with hexagonal slots. A spring is fixedly connected to the inner bottom wall of the upper hexagonal slot, and a hexagonal connecting rod adapted to the hexagonal slot is fixedly connected to the top of the spring. The hexagonal connecting rod is slidably connected to the inside of the upper hexagonal slot.

[0010] Optionally, one side of the hexagonal connecting rod, the worm gear, and the fixing frame is provided with a connected limiting hole, and a matching plug rod is inserted into the interior of each set of limiting holes.

[0011] Optionally, a pull ring is fixedly connected to one end of the insertion rod away from the fixed frame, and a rubber plug adapted to the limiting insertion hole is provided on the side of the pull ring away from the insertion rod.

[0012] A multi-layered point-type photovoltaic curtain wall system includes a photovoltaic wall panel and two sets of keels symmetrically arranged on one side of the fixed frame. Limiting rods pass through the four corners of the fixed frame. The limiting rods on the upper and lower sides are respectively fixedly connected to the two sets of keels. A limiting ring is fixedly connected to the outer side of each set of limiting rods. The limiting ring abuts against one side wall of the fixed frame. A limiting bolt is threadedly connected to the side of the limiting rod away from the keel.

[0013] Optionally, a sealing washer is provided on the outside of the limiting bolt, one side of the sealing washer abutting against the fixing frame, and the other side of the sealing washer abutting against the nut of the limiting bolt.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] (1) By adjusting the shaft, worm and worm wheel, when there is a need for indoor lighting, the adjusting shaft can be rotated, so that the adjusting shaft drives the worm to rotate through the transmission of the second bevel gear and the first bevel gear. When the worm rotates, it drives each set of worm wheels and the rotating shaft to rotate synchronously. When the rotating shaft rotates, it can drive the U-shaped fixed back plate and photovoltaic panel to rotate accordingly, thereby realizing the adjustment of the angle of each set of photovoltaic panels, increasing the distance between two adjacent sets of photovoltaic panels, so that external sunlight can shine into the room through the gap between two adjacent sets of photovoltaic panels to meet the indoor lighting needs.

[0017] (2) By setting the fixing bolts and the inner transparent glass plate, when the photovoltaic panel is damaged and needs to be repaired and maintained, the fixing bolts can be unscrewed with a wrench, and then the inner transparent glass plate can be removed from the fixing frame. Then the photovoltaic panel can be repaired and maintained, making the repair and maintenance of the photovoltaic panel convenient and quick.

[0018] (3) By setting up hexagonal connecting rods, springs and insert rods, after the two adjacent sets of photovoltaic wall panels are installed and fixed, the insert rod can be pulled out from the inside of the limiting insertion hole. Then, the corresponding hexagonal connecting rod on the lower photovoltaic wall panel is pushed upward under the elastic action of the corresponding spring, thereby inserting into the hexagonal groove at the bottom of the upper worm gear, thus realizing the connection between the upper and lower sets of worm gears. This allows the photovoltaic panels to be adjusted in the subsequent process by simply rotating one set of adjustment shafts in the same column to drive the worm gears in the same column to rotate, thereby effectively improving the efficiency of angle adjustment of the photovoltaic panels in the same column.

[0037] Working principle: During the construction of the photovoltaic curtain wall, the photovoltaic wall panel can be installed near windows or other locations on the building where sunlight is needed. For other locations near the building walls, ordinary photovoltaic wall panels can be used. When there is a need for natural light inside the building, the rectangular insert 14 can be inserted into the rectangular slot 13. Then, the crank 15 is turned, causing the adjusting shaft 12 and the second bevel gear 11 to rotate. The second bevel gear 11, when rotating, drives the first bevel gear 10 and the worm gear 9 to rotate. The worm gear 9, when rotating, drives each set of worm wheels 8 and the rotating shaft 7 to rotate, thereby causing the U-shaped fixed back plate 6 and the photovoltaic panel 5 to rotate until the photovoltaic panel 5 is rotated to a horizontal position. This allows sunlight to penetrate through the gaps between adjacent photovoltaic panels 5 and enter the room, meeting the indoor lighting needs. When there is no need for natural light inside the room, each set of photovoltaic panels 5 can be adjusted to a vertical position, allowing sunlight to shine on the photovoltaic panels 5, thus converting solar energy into electrical energy.
