Description

Technical Field

[0001] This utility model relates to a prefabricated photovoltaic building integrated balcony photovoltaic system. Background Technology

[0002] With the popularization of photovoltaic power generation technology, building-integrated photovoltaics (BIPV) has been widely used due to its ability to efficiently utilize space and effectively obtain clean energy. The application of photovoltaic systems on balconies is an important part of BIPV.

[0003] Existing balcony photovoltaic systems typically involve adding external brackets to the outside of the existing balcony structure, and then installing photovoltaic panels on these brackets. The photovoltaic system is actually installed in an extended space outside the building, rather than being integrated with the main building structure.

[0004] The existing balcony photovoltaic systems mentioned above have the following drawbacks: 1. Installing external supports on the existing balcony structure through expansion bolts or welding will damage the original balcony structure's waterproof layer and structural integrity, introducing new leakage points and structural safety risks.

[0005] 2. The design and installation quality of the external supports vary, and there is a risk of them falling off in severe weather (typhoons, blizzards), posing a significant safety hazard.

[0006] 3. The added structure is not integrated with the main building, resulting in inconsistent dynamic responses and making it prone to damage during earthquakes.

[0007] 4. The cables of photovoltaic systems can only be installed on the surface, which affects the appearance and poses a risk of aging and wear more easily.

[0008] 5. When a single component of a photovoltaic system is damaged, repair and replacement are troublesome and may require disassembling the entire external support structure. Utility Model Content

[0009] The purpose of this invention is to provide a prefabricated photovoltaic building integrated balcony photovoltaic system.

[0010] The objective of this utility model is achieved through the following technical solution: A prefabricated building-integrated photovoltaic (BIPV) balcony photovoltaic system is characterized by comprising a balcony photovoltaic frame, functional panels, and locking components. The balcony photovoltaic frame is assembled from horizontal and vertical columns via connectors. The connectors located on the periphery of the balcony photovoltaic frame are also used for connection to the main building structure. The interior of the columns is hollow, and multiple installation slots are formed on the balcony photovoltaic frame. Functional panels are installed in the installation slots, and the inner edges of the functional panels are supported on the columns. Some of the functional panels installed on the balcony photovoltaic frame are photovoltaic panels. The locking components are connected to the columns, and part of the locking components presses against the outer edge of the functional panels, thereby locking the functional panels in the installation slots.

[0011] A further technical solution of this utility model is: a sealing strip is provided on the part of the support column used to support the inner edge of the functional plate, and the inner edge of the functional plate is pressed on the sealing strip.

[0012] A further technical solution of this utility model is as follows: a bolt groove is provided in front of the column, the locking assembly includes a bolt block and a locking cover, the bolt block is installed in the bolt groove, and the bolt block is restricted in the groove by the limiting edge in front of the bolt groove, a connecting structure is provided in front of the bolt block, the locking cover is connected to the connecting structure and locked, and a pressure foot is provided on the side of the locking cover, the pressure foot presses on the outer edge of the functional plate.

[0013] A further technical solution of this utility model is as follows: the connecting structure includes a stud located in front of the bolt block and a locking nut connected to the stud. The lock cover is provided with a connecting hole, through which the stud passes. During installation, the lock cover is locked by the locking nut, so that the pressure foot of the lock cover presses against the functional plate.

[0014] A further technical solution of this utility model is as follows: the cavity extends through the frame column along the length direction, and the connector is provided with at least two connector heads. When connecting the frame column, the connector heads of the connector are inserted into the end of the cavity. Among them, some connector heads of the connector located on the outer side of the photovoltaic frame of the balcony are located on the outer side and are used to connect with the main body of the building.

[0015] A further technical solution of this utility model is as follows: the connector includes a cross-shaped connector with four connector heads, a T-shaped connector with three connector heads, and a right-angle connector with two connector heads.

[0016] A further technical solution of this utility model is: the balcony photovoltaic frame is also provided with a sealing block, which blocks the gap between the connecting positions of the frame columns.

[0017] A further technical solution of this utility model is as follows: the balcony photovoltaic system also includes an inner balcony frame, which is installed side by side behind the balcony photovoltaic frame. There is a gap between the inner balcony frame and the balcony photovoltaic frame. The inner balcony frame has the same structure as the balcony photovoltaic frame, except that the functional panels installed on the inner balcony frame are different.

[0018] A further technical solution of this utility model is that some of the functional panels installed on the photovoltaic frame of the balcony are transparent window panels.

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1. The balcony photovoltaic system of this utility model can be installed as a balcony enclosure, and it itself becomes part of the balcony structure, integrated with the main building.

[0020] 2. The support column of this utility model has a cavity, and the cables of the balcony photovoltaic system can be hidden in the cavity of the support column. This not only provides good protection for the cables and avoids the risk of aging and leakage caused by sun and rain, mechanical wear and tear on exposed cables, but also provides a better appearance.

[0021] 3. The connector of this utility model is used to connect the horizontal and vertical columns, and also to make a rigid connection with the embedded parts of the building body, so that the frame and the building body can have a reliable connection, ensuring the effective transfer of load and the overall stability of the structure. It can better eliminate the safety hazards such as structural damage, falling off and insufficient seismic performance caused by the later addition of supports in the existing technology.

[0022] 4. The maintenance of this utility model is simpler and the maintenance cost is lower. When a single component of the balcony photovoltaic system is damaged, the corresponding functional board can be easily disassembled for repair or replacement.

[0023] 5. This utility model further provides a sealing strip that works in conjunction with a locking component. Under the pressure of the locking component on the outer side of the functional plate, the inner side of the functional plate is pressed tightly against the sealing strip, making the sealing performance more reliable.

[0024] 6. The construction of this utility model does not require welding, large amounts of glue, or complex wiring, which can shorten the construction period and greatly reduce labor costs and dependence on the on-site working environment. Attached Figure Description

Example

[0031] like Figures 1 to 14 The prefabricated building-integrated photovoltaic balcony photovoltaic system shown in this embodiment includes a balcony photovoltaic frame 3, functional panels, locking components 6, sealing strips 9, sealing blocks 7, and an inner balcony frame 2 installed side by side behind the balcony photovoltaic frame 3. There is a gap between the inner balcony frame 2 and the balcony photovoltaic frame 3.

[0032] The balcony photovoltaic frame 3 is assembled from horizontal and vertical columns 8 using connectors, forming multiple square installation spaces on the frame 3. In this embodiment, the columns 8 are profiles, such as aluminum alloy profiles. Figure 8 As shown, a cavity 8.1 is formed inside the support column 8, extending through the support column 8 along its length. Besides being used for connection with connectors, the cavity 8.1 can also be used for arranging cables and electrical components of the balcony photovoltaic system. A bolt groove 8.2 is provided at the front of the support column 8, extending along the length of the support column 8 and passing through both ends. A limiting edge 8.4 protruding inwards is provided at the front of the bolt groove 8.2. The bolt groove 8.2 is used to connect with the bolt block 6.2. Additionally, the space in the bolt groove 8.2 not occupied by the bolt block 6.2 can also be used for arranging cables and electrical components of the balcony photovoltaic system. The portions of the support column 8 located on both sides of the bolt groove 8.2 support the edges of the functional panel. Sealing strip mounting grooves 8.3 are provided on the portions of the support column 8 located on both sides of the bolt groove 8.2. Sealing strips 9 are embedded in the sealing strip mounting grooves 8.3, with a portion of the sealing strip 9 protruding from the sealing strip mounting groove 8.3.

[0033] like Figures 3 to 5 As shown, the connectors in this embodiment include a cross-shaped connector 3.1 with four connector heads 3.5, a T-shaped connector 3.2 with three connector heads 3.5, and a right-angle connector 3.3 with two connector heads 3.5. When connecting the frame column 8, the connector heads 3.5 of the connectors are inserted into the ends of the cavity 8.1. Figure 1 andFigure 2 As shown, inside the balcony photovoltaic frame 3, the four columns 8 are connected at a cross-shaped joint using cross-shaped connectors 3.1. On the top and sides of the balcony photovoltaic frame 3, three columns 8 are also connected at a T-shaped joint using cross-shaped connectors 3.1, with one connector 3.5 of the cross-shaped connector 3.1 located on the outer side for fixed connection to the embedded parts on the building structure. On the bottom of the balcony photovoltaic frame 3, three columns 8 are connected at a T-shaped joint using T-shaped connectors 3.2. At the two upper corners of the balcony photovoltaic frame 3, cross-shaped connectors 3.1 are used, with the two connectors 3.5 of the corner cross-shaped connectors 3.1 located on the outer side for fixed connection to the embedded parts on the building structure. At the two lower corners of the balcony photovoltaic frame 3, T-shaped connectors 3.2 are used, with one connector 3.5 of the corner T-shaped connector 3.2 located on the outer side for fixed connection to the embedded parts on the building structure. In another embodiment, right-angle connectors 3.3 can also be used at the corners of the balcony photovoltaic frame 3.

[0034] The sealing block 7 is used to block the gap 3.4 at the connection position between the columns 8, thereby sealing the gap 3.4 at the connection position. In this embodiment, one end of the sealing block 7 is provided with a limiting head 7.1 protruding to one side. Figure 1 and Figure 2 As shown, a gap will be formed at the position where the horizontal support column 8 and the vertical support column 8 meet. The sealing block 7 is inserted into the gap, and the limiting head 7.1 of the sealing block 7 abuts against the outer surface of the connector.

[0035] The functional panels can be photovoltaic panels 4, transparent window panels 5, or decorative panels, etc., selected according to needs. The functional panels are installed in the installation spaces of the balcony photovoltaic frame 3, and the inner edges of the functional panels are supported on the sealing strips 9 of the frame column 8. In this embodiment, the upper and side functional panels of the balcony photovoltaic frame 3 are photovoltaic panels 4, and the middle functional panel is a transparent window panel 5. The inner frame 2 of the balcony will also be equipped with transparent window panels 5 at the positions corresponding to the transparent window panels 5 on the balcony photovoltaic frame 3. The positions corresponding to the photovoltaic panels 4 on the balcony photovoltaic frame 3 can be equipped with decorative panels or, alternatively, transparent window panels 5.

[0036] The distribution of photovoltaic panels 4 and perspective window panels 5 is not limited to this. In another embodiment, photovoltaic panels 4 can be arranged in the middle of the balcony photovoltaic frame 3, while perspective window panels 5 are arranged around them, or other structures that vary as needed.

[0037] like Figure 6As shown, the locking assembly 6 in this embodiment includes a bolt block 6.2 and a locking cover 6.1. The bolt block 6.2 can be inserted into the bolt groove 8.2 from both ends, and the bolt block 6.2 can be confined within the groove by the limiting edge 8.4 at the front of the bolt groove 8.2. A connecting structure is provided at the front of the bolt block 6.2, which includes a stud 6.3 provided at the front of the bolt block 6.2 and a locking nut 6.4 connected to the stud 6.3.

[0038] In this embodiment, the two sides of the lock cover 6.1 are bent vertically to the same side and then bent vertically outward to form pressure feet 6.5. The lock cover 6.1 has a connecting hole 6.6 in the middle.

[0039] like Figure 10 As shown, during installation, the stud 6.3 passes through the connecting hole 6.6, and the pressure feet 6.5 on both sides are located on both sides of the bracket 8 and in front of the functional plate. The locking nut 6.4 is connected to the stud 6.3. When the locking nut 6.4 is tightened, the front of the locking block 6.2 will abut against the inner side of the limiting edge 8.4. Under this limiting action, the pressure feet 6.5 will be pressed against the edge of the functional plate, and the inner side of the pressed edge of the functional plate will be pressed against the sealing strip 9. The sealing strip 9 will be appropriately compressed, thereby forming a reliable seal.

[0040] The inner frame 2 of the balcony has the same structure as the photovoltaic frame 3 of the balcony, except that the functional panels installed on the inner frame 2 of the balcony are different.

[0041] like Figures 11 to 13 As shown, the perspective window panel 5 in this embodiment consists of a frame 5.2, glass 5.1, and a sealing strip. The frame 5.2 has an interconnecting cavity 5.4 extending along its length. A glass groove 5.3 is located on the inner side of the frame 5.2, and the sealing strip is disposed within the glass groove 5.3. The four frames 5.2 are joined together to form a square frame via corner connectors 5.5. The corner connectors 5.5 are right-angled, with their two ends inserted into the interconnecting cavities 5.4 of the frame 5.2 for connection. The connection of the frame 5.2 uses a conventional connection method and will not be described in detail. The edge of the glass 5.1 is embedded in the glass groove and pressed against the sealing strip to form a seal. The perspective window panel 5 can have two or more layers of glass 5.1, corresponding to two or more rings of glass grooves 5.3, with spacing between the glass grooves 5.3.

[0042] Of course, in addition to the above structure, the perspective window panel 5 can also be made of insulated glass using traditional techniques.

[0043] The balcony photovoltaic system in this embodiment typically adopts a double-layer structure in which the balcony photovoltaic frame 3 and the inner balcony frame 2 are installed side by side. The balcony photovoltaic frame 3 and the inner balcony frame 2 serve as the balcony enclosure and are integrated with the main building structure.

[0044] The construction method of the balcony photovoltaic system in this embodiment is as follows: S1: The support column 8, connector, locking component 6, photovoltaic panel 4 and transparent window 5 are all manufactured in the factory. Openings are made on the support column 8 at the positions where the cables pass through and exit, and the cover plate is covered. When it is necessary to pass the cable, the cover plate can be opened. S2: On-site measurement and layout, splicing the columns 8 together to form the balcony photovoltaic frame 3 using connectors, sealing the gaps between the columns 8 using sealing blocks 7, installing the locking bolt block 6.2 of the locking component 6 into the locking bolt groove 8.2, and after splicing, fixing the outer connector 3.5 of the balcony photovoltaic frame 3 to the embedded parts of the building structure.

[0045] S3: Embed the sealing strip 9 in the sealing strip mounting groove 8.3; S4: Install the functional panel: As needed, place the transparent window panel 5, photovoltaic panel 4 or decorative panel into the corresponding installation space, and lock them into the installation space of the balcony photovoltaic frame 3 by locking component 6. The functional panel is pressed tightly against the sealing strip 9 to form a reliable seal, ensuring that the sealing strip 9 is compressed to 25%-35% of its free height; S5: Electrical connection: Connect the photovoltaic panel to connector 4 to connect the indoor inverter to the power grid; S6: Joint Treatment: A continuous sealing strip will be laid at the junction of the building structure and the balcony photovoltaic frame 3. This sealing strip can be an EPDM sponge rubber sealing strip or other high-durability closed-cell foam sealing strip. After the balcony photovoltaic frame 3 is installed, its sides will press against the sealing strip, fully compressing it (compression rate recommended to be 25%-35%), forming the first reliable physical airtight and watertight barrier. After the system installation and commissioning are completed, a high-weather-resistant silicone weather-resistant sealant or MS modified silane sealant will be applied to the joint between the balcony photovoltaic frame 3 and the wall for sealing. The sealant joint should be made into a full concave arc shape to adhere well to the substrate on both sides, achieving a second flexible seal and resisting external erosion such as ultraviolet rays and wind and rain.

[0046] The inner frame 2 of the balcony is installed after the photovoltaic frame 3 of the balcony is installed. The transparent window panel 5 will also be installed on the inner frame 2 of the balcony, corresponding to the position of the transparent window panel 5 on the photovoltaic frame 3. The decorative panel can be installed on the position of the photovoltaic panel 4 on the photovoltaic frame 3, or the transparent window panel 5 can be installed.

[0047] Of course, the balcony photovoltaic system will also be equipped with other conventional supporting components and facilities, such as a DC combiner box, which will be installed in a concealed position at the bottom of the frame during construction. The typical cable arrangement path for the balcony photovoltaic system in this embodiment is as follows: the cable leading from the photovoltaic panel 4 passes through the cavity 8.1 of the vertical column (or the space of the bolt groove 8.2 undisturbed by the bolt block 6.2), extends along the cavity 8.1 of the vertical column (or the space of the bolt groove 8.2 undisturbed by the bolt block 6.2) to the bottom of the balcony photovoltaic frame 3, and then exits to connect with the DC combiner box. The cable leading from the DC combiner box passes through the cavity 8.1 of the horizontal column (or the space of the bolt groove 8.2 undisturbed by the bolt block 6.2), extends along the cavity 8.1 of the horizontal column (or the space of the bolt groove 8.2 undisturbed by the bolt block 6.2) to the side of the balcony photovoltaic frame 3 near the wall of the main building, then exits the column, passes through the wall into the interior, and enters the indoor cable tray, and is then arranged along the indoor cable tray.

[0048] In this embodiment, the cables of the photovoltaic panel 4 are connected quickly using the MC4 quick-connect interface.

[0049] In this embodiment, the metal components of the balcony photovoltaic system, such as the frame and locking assembly 6, must be reliably grounded through a grounding wire.

[0050] Additionally, at all horizontal joints or areas prone to water accumulation, the sealant application should ensure a slight outward slope to allow rainwater to slide off smoothly and prevent water buildup. For larger gaps, a polyethylene foam backing strip can be filled inside the gap before applying sealant to the outside to prevent adhesion on three sides and control the sealant thickness.

[0051] The sealing strips mentioned above can be made of ethylene propylene diene monomer (EPDM) rubber or similar materials, possessing excellent weather resistance, high and low temperature resistance, resistance to compression set, and service life. The sealant should meet or exceed the requirements of the national standard GB / T 14683 "Silicone Building Sealants," and its displacement capacity (e.g., ±25%, ±35%) should be able to accommodate the expected structural displacement, and it should have good adhesion to concrete, metal, and glass.

[0052] The above embodiments of this utility model are not intended to limit the scope of protection of this utility model. The implementation of this utility model is not limited thereto. All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
