Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation and building integration technology, specifically an integrated system that integrates photovoltaic power generation and building facade. Background Technology

[0002] The integration of photovoltaic power generation with building facades, namely the application of building integrated photovoltaics (BIPV) on building facades, is the organic combination of solar power generation products with building facades, so that building facades can not only have traditional functions such as enclosure and decoration, but also realize the function of photovoltaic power generation.

[0003] In the prior art, patent publication number CN202022110554.0 discloses an installation structure for a photovoltaic building facade and its vertical photovoltaic curtain wall, including an upper facade panel and a lower facade panel that are fixedly installed on the building facade and are distributed vertically at intervals. An upper photovoltaic panel and a lower photovoltaic panel are respectively hung on the upper facade panel and the lower facade panel. The upper photovoltaic panel and the lower photovoltaic panel are correspondingly matched to form a photovoltaic limiting part for limiting the hanging of at least one photovoltaic module. The photovoltaic module is installed and limited on both sides with the photovoltaic limiting part.

[0004] In practical use, the aforementioned vertical photovoltaic curtain walls are troublesome to maintain. Moreover, the angle of the curtain wall is fixed after installation. When adjusting the photovoltaic curtain wall to receive stronger sunlight, additional supports need to be installed, which is cumbersome and difficult. The process of installing supports is also difficult and has a large workload. It may lead to problems such as loose bolts on some supports, resulting in lower stability and poorer wind and pressure resistance. Therefore, we propose an integrated system that integrates photovoltaic power generation and building facade. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 This embodiment provides a technical solution: an integrated system for photovoltaic power generation and building facade, including a photovoltaic connection frame 4 and a photovoltaic angle adjustment mechanism 8;

[0025] Photovoltaic connection frame 4: There are nine of them (the number and specifications of photovoltaic connection frames 4 can be reduced or added according to the size of the building facade, until all designated areas of the building facade have photovoltaic connection frames 4). Photovoltaic mounting frames 6 are rotatably connected to the upper side of the left and right inner walls of the photovoltaic connection frame 4 via upper rotating rods 5. Photovoltaic panels 7 are evenly distributed and fixed to the front side of the photovoltaic mounting frames 6. Steel cables 9 are fixedly connected to the middle of the left and right inner walls of the photovoltaic connection frame 4. Inverted L-shaped frames 3 are fixedly connected to the middle and upper side of the left and right inner walls of the photovoltaic connection frame 4. Inverted U-shaped brackets 2 are inserted into the outer surface of each inverted L-shaped frame 3. A fixing frame 1 is fixedly connected to the back of every two inverted U-shaped brackets 2 located in the same position. Evenly distributed... The bolt holes and the rear side of the fixing frame 1 are respectively fixedly connected with evenly distributed steel bar embedded parts 12. The lower side wall of the photovoltaic connecting frame 4 is respectively fixedly connected with the bottom support plate 10. The photovoltaic connecting frame 4 is equipped with a solar controller 11. The output end of the photovoltaic panel 7 is electrically connected to the input end of the solar controller 11. The output end of the solar controller 11 is electrically connected to the external battery or load equipment. During the construction of the building, the fixing frame 1 needs to be installed on the outer surface of the building through the steel bar embedded parts 12. At this time, the fixing frame 1 will be fixed on the outer surface of the building facade. At this time, the photovoltaic connecting frame 4 can be lifted, and then the inverted L-shaped frame is inserted into the inverted U-shaped bracket 2. Then the bolt holes on the inverted U-shaped bracket 2 and the bolt holes on the inverted L-shaped bracket 3 are aligned one by one. The inverted U-shaped bracket 2 and the inverted L-shaped bracket 3 are fixed by external bolts.

[0026] The photovoltaic angle adjustment mechanism 8 includes a vertical guide rail 81, a slide block 83, a lower rotating rod 84, a station plate 85, and a front fixed seat 86. The vertical guide rail 81 is respectively opened on the lower side of the left and right walls of the photovoltaic connecting frame 4. The slide blocks 83 are slidably connected inside the vertical guide rail 81. A station plate 85 is rotatably connected between every two slide blocks 83 located in the same photovoltaic connecting frame 4 via the lower rotating rod 84. A front fixed seat 86 is rotatably connected to the front side of the station plate 85. The front side of the front fixed seat 86 is fixedly connected to the lower side of the rear wall of the photovoltaic panel 7 corresponding to the longitudinal position. The photovoltaic angle adjustment mechanism 8 also includes a lead screw 82, a torsion valve 87, and a clearance groove 88. The vertical guide rail 81 is located on the right side of each photovoltaic connecting frame 4. Inside the rail 81, lead screws 82 are rotatably connected. The external thread of the lead screw 82 is threadedly connected to the middle of the slide 83 located within the same vertical guide rail 81. Torque valves 87 are fixedly connected to the upper ends of the lead screws 82. Corrugated sleeves can be installed on the upper and lower side walls of the vertical guide rail 81 with the lead screws 82. The ends of the corrugated sleeves are fixed to the outer surface of the slide 83 within the same vertical guide rail 81, sealing the external thread of the lead screw 82. When the slide 83 moves up and down, the corrugated sleeves will adaptively expand and contract to prevent contamination of the external thread of the lead screw 82. Simultaneously, the system can replace the torsion valves 87 with a motor drive and add a light angle sensor to achieve automatic adjustment of the angle of the photovoltaic connector 4 by the motor, allowing for the reception of stronger light. In the photovoltaic connection frame 4, a clearance groove 88 is provided in the middle of the right side wall. The photovoltaic angle adjustment mechanism 8 also includes a limiting rod 89. The limiting rod 89 is fixedly connected to the interior of the vertical guide rail 81 on the left side of each photovoltaic connection frame 4. The outer arc surface of the limiting rod 89 is slidably connected to the middle of the slide block 83 located in the same vertical guide rail 81. At this time, the operator can put his hand into the clearance groove 88, touch the torsion valve 87, and then twist the torsion valve 87 in the forward and reverse directions, thereby driving the screw 82 to rotate in the forward and reverse directions, thereby driving the slide block 83 in the same vertical guide rail 81 to move up and down in the vertical position. At this time, the slide block 83 can be adjusted to move downward until the slide block 83 moves to the bottom. During this period, the photovoltaic installation will be pushed by the platform 85. The frame 6 forces the central axis of the upper side rotating rod 5 of the photovoltaic mounting frame 6 to change clockwise until the upper surface of the base plate 10 firmly supports the lower surface of the station plate 85. At this time, the station plate 85 is parallel to the horizontal plane, and the photovoltaic mounting frame 6 is in an inclined state. At this time, each photovoltaic mounting frame 6 can be adjusted in sequence in the above manner. At this time, multiple station plates 85 located on the same horizontal plane form a walkable platform. Workers can walk on this platform and can be secured to the steel cable 9 with safety hooks during walking. By adjusting the station plates 85, a walking platform can be formed, which is convenient for workers to carry out daily maintenance work. At the same time, the orientation of the photovoltaic connecting frame 4 can be finely adjusted according to seasonal changes to receive stronger sunlight. When the photovoltaic panel 7 receives sunlight,When sunlight shines on the photodiodes on the photovoltaic panel 7, the photodiodes convert the sunlight into electrical energy, generating current. When many photovoltaic panels 7 are connected in parallel, they form a solar cell array with relatively high output power, transmitting the current to the solar controller 11. The solar controller 11 uses its built-in sensors to sense the state voltage, current, and temperature of the solar panels, batteries, and load. Based on preset logic such as charging curves and protection thresholds, it determines the energy distribution method and ultimately executes charging / discharging control or protection actions through circuit switches and modulation technology, achieving integrated photovoltaic power generation with the building facade design.

[0027] The working principle of the integrated photovoltaic power generation and building facade system provided by this utility model is as follows: During building construction, the fixing frame 1 needs to be installed on the outer surface of the building through the steel bar embedded part 12. At this time, the fixing frame 1 will be fixed on the outer surface of the building facade. Then, the photovoltaic connection frame 4 can be lifted, and then the inverted L-shaped frame is inserted into the inverted U-shaped bracket 2. Then, the bolt holes on the inverted U-shaped bracket 2 and the bolt holes on the inverted L-shaped frame 3 are aligned one-to-one. The inverted U-shaped bracket 2 and the inverted L-shaped frame 3 are fixed by external bolts. At this time, the workers can put their hands into the clearance groove. Inside 88, locate the torsion valve 87 and twist it in both directions. This causes the lead screw 82 to rotate in both directions, which in turn moves the slide block 83 within the same vertical guide rail 81 vertically. The slide block 83 can then be adjusted to move downwards until it reaches its lowest position. During this process, the station plate 85 pushes against the photovoltaic mounting frame 6, forcing the central axis of the upper rotating rod 5 of the photovoltaic mounting frame 6 to change clockwise until the upper surface of the base plate 10 firmly supports the lower surface of the station plate 85. At this point, the station plate 85 is parallel to the horizontal plane, and the photovoltaic mounting frame... When photovoltaic mounting bracket 6 is in an inclined position, each photovoltaic mounting bracket 6 can be adjusted sequentially using the above method. At this time, multiple mounting plates 85 located on the same horizontal plane form a walkable platform, allowing workers to walk on this platform. During the walk, they can be secured to the steel cable 9 via safety hooks. By adjusting the mounting plates 85, a walkable platform can be formed, facilitating daily maintenance work for workers. Simultaneously, the orientation of the photovoltaic mounting bracket 4 can be finely adjusted according to seasonal changes to receive stronger sunlight. When the photovoltaic panel 7 receives sunlight, when sunlight shines on the photodiodes on the photovoltaic panel 7, the photodiodes convert the sunlight energy into electrical energy, generating current. When many photovoltaic panels 7 are connected in parallel, they can form a solar cell array with relatively large output power, transmitting the current to the solar controller 11. The solar controller 11 senses the state voltage, current, and temperature of the solar panels, batteries, and load through its built-in sensors. Based on preset logic such as charging curves and protection thresholds, it determines the energy distribution method and ultimately executes charging / discharging control or protection actions through circuit switches and modulation technology, realizing the integrated design of photovoltaic power generation and building facade.

[0028] It is worth noting that the photovoltaic panel 7 and solar controller 11 disclosed in the above embodiments can be freely configured according to the actual application scenario. The photovoltaic panel 7 is a commonly used polycrystalline silicon solar panel, and the solar controller 11 is recommended to be a WONDER2-MPPT model solar controller. The photovoltaic panel 7 is connected to the solar controller 11 using a method commonly used in the prior art.
