Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic module technology, and more specifically, it relates to a photovoltaic curtain wall module. Background Technology

[0002] In response to the national call for energy conservation and emission reduction, provinces across China are actively encouraging and promoting the application of green buildings in cities. During the building operation phase, public buildings account for 8.1% of the nation's total carbon emissions. Therefore, under the premise of achieving carbon neutrality, building-integrated photovoltaics (BIPV) will become an important direction for building energy conservation. Currently, BIPV is mainly used in curtain walls, industrial and commercial roofs, and building roofs. Photovoltaic curtain walls are one form of BIPV application, organically combining photovoltaic modules with traditional curtain walls to enable them to generate electricity.

[0003] During long-term use, photovoltaic (PV) curtain walls accumulate a large amount of dust on their outer surface, affecting both power generation efficiency and aesthetics. Therefore, regular cleaning is necessary. However, current cleaning methods typically involve operators using suspended platforms to access the PV curtain wall, which is cumbersome and poses safety hazards due to the high-altitude nature of the work. Therefore, this paper researches and improves upon existing structures and shortcomings to provide a PV curtain wall component with greater practical value. Utility Model Content

Moving frames 5 are slidably connected to the inner side of each connecting frame 4. Mounting seats 6 are fixedly connected to the top side of each moving frame 5. Connecting seats 7 are rotatably connected to both ends of each mounting seat 6 via bearings. A rotating shaft 8 is mounted on the inner side of each mounting seat 6. A fixing block is fixedly mounted on one end of each rotating shaft 8. Connecting grooves are provided on adjacent sides of each connecting seat 7.

[0028] Among them, a limiting ring 11 is fixedly installed on the outer side of the rotating shaft 8, and a spring 12 is sleeved on the outer side of the rotating shaft 8. The two ends of the spring 12 abut against one side of the moving block 10 and one side of the limiting ring 11, respectively, to prevent the moving block 10 from disengaging from the connecting seat 7 when it is not subjected to external force.

[0029] A sleeve 13 is fixedly installed on the outer side of one end of the movable block 10. The inner side of the sleeve 13 is slidably connected to the outer side of the limiting ring 11, which can conveniently drive the movable block 10 to move and protect the spring 12.

[0030] The rotating shaft 8 has a limiting block at one end, and the moving block 10 has a through hole on its inner side that is slidably connected to the limiting block to prevent the moving block 10 from falling off the rotating shaft 8.

[0031] The movable frame 5 is equipped with a motor 15 fixedly mounted on one side. The output end of the motor 15 passes through one side of the movable frame 5 and is fixedly mounted with a gear 16. The inner side of the connecting frame 4 is fixedly mounted with a rack 17 that meshes with the gear 16, which can realize the stable movement of the movable frame 5.

Multiple sets of brackets 19 are symmetrically fixedly installed on one side of the fixed housing 18. The top side of the mounting rod 1 is provided with a sliding groove. The multiple sets of brackets 19 are slidably connected to the inner side of the two sets of sliding grooves, so that the photovoltaic curtain wall body 2 can be conveniently hung on the mounting rod 1 before installation, so as to facilitate the subsequent fixing of the photovoltaic curtain wall body 2.

[0034] The top of each connecting frame 4 is fixedly mounted with a fixing plate 20 by fasteners to prevent the moving frame 5 from detaching from the connecting frame 4. The top side of the fixing plate 20 is fixedly mounted with a rain cover 21 corresponding to the mounting seat 6 and the brush 9 to prevent rainwater from falling on the brush 9 and causing the brush 9 to get damp.

The top opening of the connecting frame 4 on the bottom side of the photovoltaic curtain wall body 2 corresponds to the bottom opening of the connecting frame 4 on the top side of the photovoltaic curtain wall body 2. At this time, the upper and lower sets of racks 17 are close together and can both mesh with the gears 16. After the photovoltaic curtain wall body 2 is hung, it is fixed with fasteners. The power cord of the photovoltaic curtain wall body 2 is then connected indoors in series. The inverter connects motor 14 and motor 25 to the indoor controller via wires and is powered by an external power source. Fixing plates 20 are fixedly installed on both the top and bottom openings. When it is necessary to clean the dust on the outside of the photovoltaic curtain wall body 2, the controller starts motor 14 to drive the connecting seat 7 to rotate. The connecting seat 7 drives the rotating shaft 8 and brush 9 to rotate. At the same time, motor 215 is started to drive gear 16 to rotate. Gear 16 drives the moving frame 5 to move through rack 17. The moving frame 5 drives the mounting seat 6 and brush 9 to move, and automatically cleans the outer surface of the photovoltaic curtain wall body 2.
