Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of roof structure, and particularly relates to a roof structure with photovoltaic components. BACKGROUND

[0002] The core function of a traditional roof is waterproofing, heat insulation and load bearing, and asphalt shingle roofs need to be replaced every 10-15 years, which has a high overall cost. Meanwhile, the production and transportation of traditional roof materials (such as asphalt) involve a large amount of carbon emissions (about 200 kg CO2 / ㎡). With the promotion of global energy transformation and the "double carbon" target, the roof structure is extended from "passive protection" to "active power generation", so photovoltaic roofs are introduced. The photovoltaic roof not only integrates solar cell components into the roof structure layer, converts light energy into electrical energy through the photoelectric effect, but also bears the functions of waterproofing, heat insulation and load bearing of the building.

[0003] Because the size of the roof of each household is different, and in order to facilitate the transportation of the roof structure to the specified area by the staff, the roof structure needs to be modularly split and then assembled in the site. In this process, the existing splicing process is relatively complex, and because the roof structure needs to be maintained, if a single component is found to be damaged, the photovoltaic tile needs to be disassembled and reinstalled with a waterproof layer piece by piece, which results in low overall installation efficiency.

[0007] Optionally, the two sides of the photovoltaic panel setting frame are fixedly provided with bolt positioning plug-in plates, and the bolt positioning plug-in plates are plugged on the top of the H-shaped positioning guide rail.

[0008] Optionally, the bolt positioning plug-in plate extending to one side of the top of the H-shaped positioning guide rail is fixedly provided with an extension plate, the top of the extension plate is fixedly provided with a side bolt positioning plate, and the top of the side bolt positioning plate is fixedly provided with a clamping positioning frame.

[0009] Optionally, the outer side of the clamping positioning frame is connected with a sealing cover through bolts, and the sealing cover is arranged in a sealing state opposite to the side bolt positioning plate.

[0010] Optionally, two of the H-shaped positioning guide rails are plugged on the bottom of the photovoltaic panel setting frame, and the remaining one H-shaped positioning guide rail is plugged on the bottom of the photovoltaic panel.

[0011] Optionally, the bottom of the detachable photovoltaic module is provided with a heat exchange assembly, the heat exchange assembly is wrapped in the inside of the photovoltaic panel setting frame and the rock wool sandwich panel, and the heat exchange assembly is located directly below the photovoltaic panel.

[0012] Optionally, the multi-arc positioning rod is composed of round rods with different diameters, and the multi-arc positioning rod is plugged in the inside of the clamping positioning frame.

[0015] In summary, this application includes at least one of the following beneficial technical effects: Under the guiding pressure of the triangular positioning rod track, the insertion rod slides inward along the triangular positioning rod track. At the same time, the insertion rod drives the mating insertion block to slide along the slide rail block. The mating insertion block drives the adaptive clamping plate to clamp and position the rock wool sandwich panel. The photovoltaic panel mounting frame is positioned and clamped during installation, so that it meets the installation position requirements better. When the mating insertion block drives the adaptive clamping plate to move outward, the pressing rod presses down on the adaptive clamping plate to press down and position it at this time, further improving the stability of the rock wool sandwich panel under positioning, thereby improving the standardization and stability of the roof structure installation. The multi-arc positioning rod rotates smoothly to a certain degree and gets stuck in the cavity of the locking positioning frame. Since the surface of the multi-arc positioning rod is uneven, if the rock wool sandwich panel and the photovoltaic panel mounting frame undergo thermal expansion and contraction, the multi-arc positioning rod will be subjected to a reverse thrust. Because the multi-arc positioning rod is stuck in the cavity of the locking positioning frame, the unevenness of the cavity will generate a corresponding counterforce on the multi-arc positioning rod, which further improves the stability of the photovoltaic panel mounting frame installation and reduces the impact of thermal expansion and contraction on the roof components.

[0023] As Figures 1 to 4 shown, the roof structure with photovoltaic module proposed by the application includes a detachable photovoltaic module 1, three H-shaped positioning guide rails 2 are installed at the bottom of the detachable photovoltaic module 1, photovoltaic module auxiliary positioning assemblies 3 are installed at the two sides of the detachable photovoltaic module 1, a rock wool sandwich panel 6 is installed at the bottom of the detachable photovoltaic module 1, a Z-shaped positioning plate 5 is installed at the bottom of the H-shaped positioning guide rail 2, the detachable photovoltaic module 1 includes a photovoltaic panel placing frame 101 fixedly installed at the bottom of the rock wool sandwich panel 6, a photovoltaic panel 102 is fixedly installed at the top of the photovoltaic panel placing frame 101, a heat exchange assembly 4 is installed at the bottom of the detachable photovoltaic module 1, the heat exchange assembly 4 is wrapped inside the photovoltaic panel placing frame 101 and the rock wool sandwich panel 6, the heat exchange assembly 4 is located directly below the photovoltaic panel 102, bolt positioning plugs 103 are fixedly installed at the two sides of the photovoltaic panel placing frame 101, the bolt positioning plugs 103 are inserted into the top of the H-shaped positioning guide rail 2, three H-shaped positioning guide rails 2 are fixedly installed at the top of the roof by means of bolts or welding, the three H-shaped positioning guide rails 2 are respectively located at the two sides and the central position of the top of the roof, and the Z-shaped positioning plate 5 is installed at the bottom of the H-shaped positioning guide rail 2 by means of bolts or welding, so that the roof is completed to be built, then the single photovoltaic panel placing frame 101 is inserted into the position of the H-shaped positioning guide rail 2, since there is a protruding block at the bottom of the photovoltaic panel placing frame 101, the single photovoltaic panel placing frame 101 moves towards the top of the single-sided H-shaped positioning guide rail 2 until the protruding block of the photovoltaic panel placing frame 101 is firstly inserted into the groove at the top of the H-shaped positioning guide rail 2 which is matched with it, and the other side of the single photovoltaic panel placing frame 101 is inserted into the inside of the central H-shaped positioning guide rail 2, thus the single photovoltaic panel placing frame 101 is preliminarily positioned, and the remaining multiple photovoltaic panel placing frames 101 are assembled in the above-mentioned manner, then the bolt positioning plugs 103 are aligned with the holes opened on the surfaces of the two-sided H-shaped positioning guide rails 2, then the screw rods are rotated and installed inside the holes opened in the bolt positioning plugs 103 and the H-shaped positioning guide rails 2, since the groove width at the top of the H-shaped positioning guide rail 2 is fixed, after the two-sided photovoltaic panel placing frames 101 are fixed, they will generate mutual thrust force at the top of the H-shaped positioning guide rail 2 which is located at the central position, thereby improving the stability of the photovoltaic panel placing frame 101 during installation, it is explained here that the sealant can be filled at the joint of the two photovoltaic panel placing frames 101 to improve the waterproofness of the roof, finally the photovoltaic panel 102 is fixedly installed at the top of the photovoltaic panel placing frame 101 to complete the installation of the photovoltaic module, according to the above-mentioned manner, the installation position of the photovoltaic module can be quickly determined to realize the modular positioning installation of the roof structure.

[0024] Meanwhile, during the installation of the photovoltaic panel 102 and the photovoltaic panel mounting frame 101, the rock wool sandwich panel 6, which reduces the impact of temperature on the indoor environment and reduces the transmission of external noise, can be installed between the photovoltaic panel mounting frame 101 and the H-shaped positioning guide rail 2. Since the efficiency of the photovoltaic panel 102 decreases with increasing temperature, with a temperature coefficient of approximately -0.4% / ℃, and the output power decreases by 10%-15% when the summer temperature is >35℃, a heat exchange component 4 for adjusting the surface temperature of the photovoltaic panel 102 is fixedly installed at the bottom of the photovoltaic panel 102.

[0025] As one implementation method, such as Figures 1 to 4 As shown, two H-shaped positioning rails 2 are inserted into the bottom of the photovoltaic panel mounting frame 101, and the remaining H-shaped positioning rail 2 is inserted into the bottom of the photovoltaic panel 102. A first waterproof sealing strip is provided at the connection between the photovoltaic panel mounting frame 101 and the photovoltaic panel 102, a second sealing strip is provided at the connection between the photovoltaic panel mounting frame 101 and the H-shaped positioning rail 2, and a third waterproof sealing strip is provided at the connection between the H-shaped positioning rail 2 and the roof. Since the roof components are installed in a modular manner, waterproof sealing is performed at each connection. At the same time, a water storage component, which is a water collection tank or a drainage pipe, is provided between the H-shaped positioning rail 2 and the detachable photovoltaic module 1 to guide and release any water that may flow in.

[0026] As one implementation method, such as Figures 5 to 10As shown, the photovoltaic module auxiliary positioning assembly 3 comprises a positioning metal plate 301 bolted at the bottom end of the rock wool sandwich panel 6, the top of the positioning metal plate 301 is fixedly installed with two groups of sliding rail blocks 302, the top end of the two groups of sliding rail blocks 302 is slidingly installed with a matching plug-in block 303, the two sides of the matching plug-in block 303 are fixedly installed with plug-in rods 314, the outer side of the plug-in rods 314 is slidingly installed with a triangular positioning rod 308, the side of the triangular positioning rod 308 away from the sliding rail block 302 is fixedly installed with a sleeve rod 309, the top of the sleeve rod 309 is attached with a pushing plate 307, the inside of the pushing plate 307 is fixedly installed with a stainless steel metal rod 306, the bottom of the stainless steel metal rod 306 is fixedly installed with a downward pressing rod 305, the top of the positioning metal plate 301 is fixedly installed with an auxiliary positioning frame 310, one side of the auxiliary positioning frame 310 is fixedly installed with a clamping metal frame 311, the outer side of the clamping metal frame 311 is hinged with a multi-arc positioning rod 312, the multi-arc positioning rod 312 and the stainless steel metal rod 306 are hinged with a bidirectional positioning frame 313, the inside of the Z-shaped positioning plate 5 is slidingly installed with an adaptive clamping plate 315, the adaptive clamping plate 315 is fixedly installed on one side of the matching plug-in block 303, the rock wool sandwich panel 6 is inserted at the top of the adaptive clamping plate 315. It is explained here that except for the multi-arc positioning rod 312, the auxiliary positioning frame 310 and the bidirectional positioning frame 313 exposed to the outside air, the other components of the photovoltaic module auxiliary positioning assembly 3 are located inside the house, at the same time, the multi-arc positioning rod 312, the bidirectional positioning frame 313, the stainless steel metal rod 306 and the auxiliary positioning frame 310 are all made of stainless steel, which is less affected by rainwater corrosion and can be easily used later. In the process of fixing and installing the photovoltaic panel mounting rack 101 on the H-shaped positioning guide rail 2, the rock wool sandwich panel 6 is first inserted into the inside of the photovoltaic panel mounting rack 101, and the adaptive clamping plate 315 is towards the side of the photovoltaic panel mounting rack 101. At this time, the bottom of the rock wool sandwich panel 6 is inserted into the inside of the adaptive clamping plate 315, then the staff manually pushes the multi-arc positioning rod 312 to move downward, the multi-arc positioning rod 312 drives the bidirectional positioning frame 313 to move downward, because the two sides of the pushing plate 307 are limited by the guide rail 304, so the bidirectional positioning frame 313 drives the stainless steel metal rod 306 and the pushing plate 307 to move downward along the guide rail 304. In this process, the pushing plate 307 will extrude the sleeve rod 309, the sleeve rod 309 drives the triangular positioning rod 308 to deflect downward, the end of the triangular positioning rod 308 away from the sleeve rod 309 will move upward, at this time the track of the triangular positioning rod 308 will extrude the plug-in rod 314, under the guide pressure of the track of the triangular positioning rod 308, the plug-in rod 314 will slide inward along the track of the triangular positioning rod 308, at the same time, the plug-in rod 314 drives the matching plug-in block 303 to slide along the sliding rail block 302, the matching plug-in block 303 drives the adaptive clamping plate 315 to clamp and position the rock wool sandwich panel 6, at the same time, the photovoltaic panel mounting rack 101 connected with the rock wool sandwich panel 6 will also be clamped in the same way,The photovoltaic panel mounting rack 101 is clamped and positioned during installation, which can better meet the installation requirements of the installation position, and when the self-adapting clamping plate 315 is driven outward by the matching block 303, the lower pressing rod 305 generates downward pressure on the self-adapting clamping plate 315 to position the position at this time, further improving the stability of the positioning of the rock wool sandwich panel 6, thereby improving the normativity and stability of the installation of the roof structure.

[0027] Meanwhile, the vertical surface of the self-adapting clamping plate 315 in contact with the rock wool sandwich panel 6 is composed of two layers, and there are multiple reset springs between the two layers, which can help the self-adapting clamping plate 315 to fully clamp the rock wool sandwich panel 6 of different widths.

[0028] Further, the top of the positioning metal plate 301 is fixedly installed with two guide rails 304, and the two guide rails 304 are slidingly installed in the inside of the pushing plate 307, and the two guide rails 304 position the pushing plate 307, and also position the downward movement distance of the bidirectional positioning rack 313.

[0029] Further, the multi-arc positioning rod 312 is composed of round rods of different diameters, the multi-arc positioning rod 312 is inserted into the inside of the clamping positioning rack 106, the extension plate 104 is fixedly installed on one side of the top of the H-shaped positioning guide rail 2, the extension plate 104 is fixedly installed on the top of the side edge bolt positioning plate 105, the clamping positioning rack 106 is fixedly installed on the top of the side edge bolt positioning plate 105, the sealing cover is connected to the outside of the clamping positioning rack 106 through bolts, the sealing cover and the side edge bolt positioning plate 105 are arranged in a relative sealing state, the maximum deflection distance of the multi-arc positioning rod 312 is 90 degrees, the multi-arc positioning rod 312 is rotated to 90 degrees, and the multi-arc positioning rod 312 is clamped in the cavity of the clamping positioning rack 106. Since the surface of the multi-arc positioning rod 312 is uneven, if the rock wool sandwich panel 6 and the photovoltaic panel mounting rack 101 expand and contract due to heat, the multi-arc positioning rod 312 will be subjected to a reverse thrust. Since the multi-arc positioning rod 312 is clamped in the cavity of the clamping positioning rack 106, and the material of the multi-arc positioning rod 312 is less affected by thermal expansion and contraction, the uneven cavity will generate a corresponding counterforce on the multi-arc positioning rod 312, further improving the stability of the installation of the photovoltaic panel mounting rack 101 and reducing the influence of thermal expansion and contraction on the roof assembly.

[0030] It is explained here that the staff can threadedly connect the cover with the side edge bolt positioning plate 105 to shield the multi-arc positioning rod 312, the clamping metal rack 311 and the auxiliary positioning rack 310, cooperate with the blocking of other parts of the photovoltaic assembly auxiliary positioning assembly 3 of the roof, and avoid rainwater from entering the roof.

[0031] Through the above mounting mode, the roof assembly can be quickly positioned, and when any photovoltaic assembly needs to be repaired, the corresponding photovoltaic assembly can be removed by reversely pulling the multi-arc positioning rod 312, thereby improving the mounting and dismounting speed of the roof structure.

[0032] The above specific embodiments are only several optional embodiments of the present application, and based on the technical solutions of the present application and the related inspiration of the above embodiments, those skilled in the art can make various alternative improvements and combinations on the above specific embodiments.
