Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, and in particular to a building photovoltaic roof. Background Technology

[0002] With the development of a green and low-carbon economy, people are paying increasing attention to environmentally friendly energy, especially in the application of solar energy to low-carbon buildings. This has led to the emergence of photovoltaic (PV) roofs based on solar photovoltaic panels. A PV roof is a roof structure that integrates photovoltaic products onto a building's roof. Most of these structures involve installing PV panels on the roof to more comprehensively absorb and utilize solar energy. To install solar panels on a building roof, a support bracket is needed to connect the roof and the PV units.

[0003] A current Chinese patent publication number, CN222147469U, discloses a photovoltaic roof for low-carbon buildings, including photovoltaic panels and several installation structures for fixing the photovoltaic panels. The installation structures include mounting rods and several support components for fixing the mounting rods. The support components include Z-shaped supports, U-shaped connectors, and clamps. One end of the Z-shaped support is fixedly connected to one side of the mounting rod, and the other end is fixedly connected to one side of the U-shaped connector. This utility model designs an installation structure for fixing photovoltaic panels. The installation structure includes mounting rods and support components. The support components include Z-shaped supports, U-shaped connectors, and clamps. The clamps can be fixed to the supporting longitudinal beams of the roof, thus avoiding damage to the roof's supporting structural strength. The Z-shaped supports can pass through the gaps between adjacent tiles, thus avoiding damage to the tiles and ensuring the structural strength and waterproof performance of the roof.

[0004] However, in actual use, the above-mentioned device requires removing the tiles to install the "Z"-shaped support, "└"-shaped connector and clamp. This installation method is cumbersome, and removing the tiles on the roof reduces the standing area for workers, posing a safety hazard. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a building photovoltaic roof.

[0006] One of the objectives of this utility model is achieved through the following technical solution: A building photovoltaic roof includes a roof with two mounting beams at the top. Each mounting beam has a fixing member at both ends. The fixing member has a limiting groove at its top. The mounting beams have two circular grooves and several mounting holes at their tops. Hexagonal socket screws are movably inserted into the inner cavity of each circular groove. A screw hole is formed at the bottom of the inner cavity of each limiting groove. A second through hole is formed at the bottom of each fixing member. The roof has two connecting strips at its bottom, each connecting strip having two first through holes and two expansion screws at its bottom.

[0007] Furthermore, the two ends of the fixing member are movably inserted into the inner cavity of the adjacent limiting groove, and the cross-section of the fixing member is an isosceles trapezoid.

[0008] Furthermore, the bottom end of the internal hexagon screw is inserted into the inner cavity of the screw hole, and the internal hexagon screw is threadedly connected to the screw hole.

[0009] Furthermore, the fastener is located on one side of the roof, and the sidewall of the roof is in contact with the inner side of the fastener.

[0010] Furthermore, the top of the connecting strip fits into the bottom of two adjacent fasteners, the top of the expansion screw moves through the first and second through holes, and the fasteners and connecting strip are installed at the bottom of the roof by the expansion screw.

[0011] Furthermore, the top of the hexagon socket screw is flush with the bottom of the inner cavity of the limiting groove, and the hexagon socket screw matches the circular groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model relates to a building photovoltaic roof. When installing photovoltaic panels, the device does not require removing the roof tiles. Simply move two mounting beams to the top of the roof, then move the fixing components, and then fix the mounting beams in the inner cavity of the limiting groove with hexagonal screws. Finally, move the top of the expansion screw through the first and second through holes. The fixing components and connecting strips are installed at the bottom of the roof with expansion screws, thus completing the installation of the two mounting beams. After that, the photovoltaic panels are installed on the top of the mounting beams. The installation operation is simple and does not require removing the roof tiles, which greatly reduces the risk factor during installation. 2. This utility model provides a building photovoltaic roof. By setting a connecting strip, the distance between two adjacent fixing parts is limited, thereby avoiding the limitation of the distance between two installation beams and thus preventing the position of the installation beams from shifting, thereby improving the stability of the photovoltaic panels after installation.

[0019] Please see Figure 1-6 A building photovoltaic roof includes a roof 1, with two mounting beams 2 on the top of the roof 1. Fixing members 3 are located at both ends of the mounting beams 2, with the fixing members 3 situated on one side of the roof 1. The sidewall of the roof 1 is in contact with the inner side of the fixing members 3. A limiting groove 4 is formed on the top of the fixing member 3, and both ends of the fixing member 3 are movably inserted into the inner cavity of the adjacent limiting groove 4. The cross-section of the fixing member 3 is an isosceles trapezoid. Two circular grooves 5 and several mounting holes 7 are formed on the top of the mounting beams 2. Hexagon socket screws 6 are movably inserted into the inner cavity of the circular grooves 5. A screw hole 12 is formed at the bottom of the inner cavity of the limiting groove 4, and the bottom end of the hexagon socket screw 6 is inserted into the inner cavity of the screw hole 12. The hexagon socket screw 6 is threaded into the screw hole 12, and the top of the hexagon socket screw 6 is flush with the bottom of the inner cavity of the limiting groove 4. The hexagon socket screw 6 matches the circular groove 5. A second through hole 11 is formed at the bottom of the fixing member 3, and the top end of an expansion screw 8 movably passes through the second through hole 11.

[0020] In the above embodiment, during use, the two mounting beams 2 are first moved to the top of the roof 1, and then the fixing part 3 is moved. When the fixing part 3 is moved, the limiting groove 4 is aligned with the mounting beam 2. Then the fixing part 3 is moved to the side wall of the roof 1. At this time, the mounting beam 2 is inserted into the inner cavity of the limiting groove 4, and then the mounting beam 2 is fixed in the inner cavity of the limiting groove 4 by the internal hexagon screw 6. Example

[0021] Please see Figure 7 and Figure 8 The bottom of the roof 1 is provided with two connecting strips 9. The top of the connecting strips 9 fits into the bottom of two adjacent fasteners 3. Two first through holes 10 are opened on the connecting strips 9. Two expansion screws 8 are provided at the bottom of the connecting strips 9. The top of the expansion screws 8 moves through the first through hole 10 and the second through hole 11. The fasteners 3 and the connecting strips 9 are installed at the bottom of the roof 1 by the expansion screws 8.

[0022] In the above embodiment, during use, the connecting strip 9 is moved to the bottom of two adjacent fixing parts 3, and then the expansion screw 8 is moved so that the top of the expansion screw 8 passes through the first through hole 10 and the second through hole 11. The fixing parts 3 and the connecting strip 9 are installed at the bottom of the roof 1 by the expansion screw 8, thereby completing the installation operation of the two mounting beams 2. Then, the photovoltaic panel is installed on the top of the mounting beam 2. The photovoltaic panel is installed by external screws cooperating with the mounting holes 7.

[0023] Working Principle: This utility model relates to a building photovoltaic roof. In use, firstly, two mounting beams 2 are moved to the top of the roof 1. Then, the fixing member 3 is moved, aligning the limiting groove 4 with the mounting beam 2. The fixing member 3 is then moved to the side wall of the roof 1, where the mounting beam 2 is inserted into the inner cavity of the limiting groove 4. The mounting beam 2 is then fixed in the inner cavity of the limiting groove 4 using hexagonal socket screws 6. After connecting both ends of the two mounting beams 2 to the corresponding fixing members 3, the connecting strip 9 is moved to the bottom of two adjacent fixing members 3. Then, the expansion screw 8 is moved, allowing the top of the expansion screw 8 to pass through the first through hole 10 and the second through hole 11. The fixing member 3 and the connecting strip 9 are installed at the bottom of the roof 1 using the expansion screw 8, thus completing the installation of the two mounting beams 2. Afterward, photovoltaic panels are installed on the top of the mounting beams 2, and the photovoltaic panels are installed by external screws engaging with the mounting holes 7.

[0024] When installing photovoltaic panels, this device eliminates the need to remove the roof tiles. Simply move the two mounting beams 2 to the top of the roof 1, then move the fixing member 3, and finally fix the mounting beams 2 into the inner cavity of the limiting groove 4 using hexagon socket screws 6. Finally, move the top of the expansion screw 8 through the first through hole 10 and the second through hole 11. The fixing member 3 and the connecting strip 9 are installed at the bottom of the roof 1 using the expansion screw 8, thus completing the installation of the two mounting beams 2. After that, the photovoltaic panels are installed on top of the mounting beams 2. The installation operation is simple and does not require removing the roof tiles, greatly reducing the risk factor during installation.

[0025] By setting the connecting strip 9, the distance between two adjacent fixing parts 3 is limited, thereby avoiding the limitation of the distance between two mounting beams 2, and thus avoiding the displacement of the mounting beams 2, thereby improving the stability of the photovoltaic panel after installation.
