Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel installation, and in particular to an installation structure of a BIPV building photovoltaic panel. Background Art

[0002] BIPV building photovoltaic panels are an innovative solution that integrates photovoltaic components with building materials. They can not only provide renewable energy for buildings, but also serve as decorative materials for building exterior walls, roofs and other parts, achieving a perfect combination of buildings and photovoltaic power generation. BIPV (Building Integrated Photovoltaics) is an innovative application that combines photovoltaic power generation technology with architectural design. The advantage of this technology is that it can effectively combine the green energy of buildings with the appearance of buildings, making buildings more environmentally friendly and intelligent, reducing energy consumption and operating costs, thereby greatly improving the return on investment of buildings.

[0003] The basic principle of the BIPV system is to lay a solar photovoltaic array on the roof, and the DC power generated by it is boosted by the primary DC-DC converter and tracked for the maximum power point, and then converted into AC power with the same frequency and phase as the power grid through the inverter device. Most of the power generated by it is consumed by the electrical equipment in the building, and the excess power is injected into the power grid. In the case of low photovoltaic power generation output, the load in the building can draw power from the power grid.

[0004] When installing BIPV building photovoltaic panels, the photovoltaic panels are installed through colored steel tiles and fixings through bolts. However, it is necessary to reserve gaps on the roof during installation, thereby increasing the number of components for installing photovoltaic panels. During later maintenance, construction workers cannot step directly on the photovoltaic panels, and it is necessary to reserve operation and maintenance channels on the roof, thereby reducing the laying rate of roof photovoltaic modules. Utility Model Content

[0005] In order to achieve the above object, the utility model is implemented through the following technical solutions:

[0006] A mounting structure for BIPV building photovoltaic panels comprises a purlin support plate bolted to a roof and a purlin bolted to one side of an upper portion of the purlin support plate, a roof tile connector bolted to the top of the purlin, a corrugated steel plate disposed on the upper portion of the roof tile connector, a fastener clamped between two corrugated steel plates, a photovoltaic module disposed between the two fasteners and on the upper portion of the corrugated steel plate, and thermal insulation cotton disposed between two purlins.

[0007] More preferably, the corrugated steel sheet comprises:

[0008] Support part.

[0009] The extension parts are symmetrically welded at both ends of the supporting part.

[0010] The connecting portion is symmetrically arranged at an end position away from the extending portion.

[0011] Further preferably, the height of the supporting portion is equal to the height of the two connecting portions, and the extension portion between the two connecting portions and at the middle position of the top of the roof tile connector engages with each other.

[0012] Further preferably, the fastener comprises:

[0013] The pressing block connecting piece is arranged on the upper part of the supporting part.

[0014] The rubber pad is arranged between the pressing block connector and the photovoltaic module.

[0015] The connecting bolt passes through the middle position of the rubber pad, and the connecting bolt is bolted inside the supporting part.

[0016] Further preferably, a screw hole having a size corresponding to the position of the connecting bolt is provided at a middle position of the upper portion of the support portion.

[0017] Compared with the prior art, the utility model has the following advantages: through the mutual cooperation between the purlin support plate, the purlin and the roof tile connector, the corrugated steel plate and the fasteners, when installing the photovoltaic module, the two corrugated steel plates are mutually engaged, thereby improving the stability of the photovoltaic module installation, thereby making the photovoltaic module steppable, and during the construction and later maintenance, the construction personnel can step on the photovoltaic module to operate, and on this basis, there is no need to reserve an operation and maintenance channel, thereby increasing the laying rate of the roof photovoltaic module and improving the power generation income, and when the two corrugated steel plates are engaged at the bottom of the photovoltaic module, the connection structure between the photovoltaic module and the color steel tile is cancelled and there is no need to reserve a gap for locking the edge, thereby reducing the number of components used in the installation of the photovoltaic module, thereby saving installation costs, and further simplifying the installation process of the photovoltaic module, and improving the installation stability between the photovoltaic module and the corrugated steel plate.

[0026] The following is combined with Figures 1 to 7 The utility model is further introduced in detail.

[0027] A BIPV building photovoltaic panel installation structure, such as Figure 1 and Figure 7 As shown, it includes a purlin support plate 1 bolted to the roof and a purlin 2 bolted to one side of the upper part of the purlin support plate 1. Further, the purlin support plate 1 is arranged at equal intervals along the length direction of the roof, and the top of the purlin 2 is bolted with a roof tile connector 3. Further, an extension portion is provided at the middle position of the upper part of the roof tile connector 3, and corrugated steel plates 4 are symmetrically clamped on both sides of the upper part of the roof tile connector 3. A fastener 5 is commonly clamped between the upper parts of the two corrugated steel plates 4, a photovoltaic module 6 is commonly arranged between the two fasteners 5 and the upper part of the corrugated steel plate 4, and a thermal insulation cotton 7 is commonly arranged between the two purlins 2.

[0028] Through the mutual cooperation between the purlin support plate 1, the purlin 2 and the roof tile connector 3, the corrugated steel sheet 4 and the fastener 5, when installing the photovoltaic module 6, the two corrugated steel sheets 4 are mutually engaged, thereby improving the stability of the installation of the photovoltaic module 6, thereby making the photovoltaic module 6 steppable. During construction and later maintenance, construction personnel can step on the photovoltaic module 6 for operation. On this basis, there is no need to reserve an operation and maintenance channel, thereby increasing the laying rate of the roof photovoltaic module 6 and improving the power generation income. When the two corrugated steel sheets 4 are engaged at the bottom of the photovoltaic module 6, the connection structure between the photovoltaic module 6 and the color steel tile is cancelled and there is no need to reserve a gap for locking the edge, thereby reducing the number of components used in the installation of the photovoltaic module 6, thereby saving installation costs. Further, the installation process of the photovoltaic module 6 is simplified, and the installation stability between the photovoltaic module 6 and the corrugated steel sheet 4 is improved.

[0029] Specifically, Figure 2 and Figure 3 As shown, the corrugated steel plate 4 includes:

[0030] The support portion 41 , further, has a shape of a vertical rectangle with an open top.

[0031] The extension portions 42 are symmetrically welded to the two ends of the support portion 41 . Specifically, opposite ends of the two extension portions 42 are welded to the two sides of the upper opening of the support portion 41 .

[0032] The connecting portion 43 is symmetrically arranged at an end position away from the extending portion 42 . Furthermore, the connecting portion 43 is curved.

[0033] Specifically, Figure 2 and Figure 3 As shown, the height of the supporting portion 41 is equal to the height of the two connecting portions 43, and the extension portion between the two connecting portions 43 and the middle position of the top of the roof tile connecting member 3 are meshed with each other.

[0034] Furthermore, when installing the corrugated steel sheet 4, the connecting parts 43 and the extension parts of the two corrugated steel sheets 4 are mutually engaged, thereby improving the stability of the installation of the corrugated steel sheet 4, further ensuring that the metal material of the roof does not deform under the conditions of thermal expansion and contraction, ensuring that the roof connection is not punched, and the operation and maintenance channel reserved on the roof can be perfectly combined with the components to avoid height differences. After the components are installed, they have a protective effect on the roof panel, extending the service life of the roof and the roof peak height is high. A certain distance is left between the components to form a complete air duct, and the circulation of air takes away the heat generated by the roof photovoltaic components.

[0035] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 As shown, the fastener 5 comprises:

[0036] The pressing block connecting member 51 is disposed on the upper portion of the supporting portion 41 .

[0037] The rubber pad 52 is arranged between the pressing block connector 51 and the photovoltaic module 6 .

[0038] The connecting bolt 53 passes through the middle position of the rubber pad 52 , and the connecting bolt 53 is bolted inside the supporting portion 41 .

[0039] Specifically, a screw hole having a size corresponding to the position of the connecting bolt 53 is provided at the middle position of the upper portion of the supporting portion 41 .

[0040] Furthermore, when installing the photovoltaic component 6, the pressing block connector 51 clamps the photovoltaic component 6 on the support part 41 through the rubber pad 52, and the pressing block connector 51 is installed inside the support part 41 through the connecting bolts 53, thereby improving the stability of installing the photovoltaic component 6.

[0041] How it works

[0042] When installing the photovoltaic module 6, first bolt the purlin 2 on the purlin support plate 1, then engage the opposite sides of the two corrugated steel sheets 4 and the extended portion at the middle position of the top of the roof tile connector 3, bolt the roof tile connector 3 on the top of the purlin 2 to achieve the installation of the corrugated steel sheet 4, and install the thermal insulation cotton 7 between two adjacent purlins 2. Finally, the block connector 51 clamps the photovoltaic module 6 on the support part 41 through the rubber pad 52, and the block connector 51 is installed inside the support part 41 through the connecting bolts 53 to achieve the installation of the photovoltaic module 6.

[0043] This specific embodiment is merely an explanation of the utility model, and it is not a limitation of the utility model. After reading this specification, those skilled in the art can make non-creative modifications to the embodiment as needed, but as long as it is within the protection scope of the utility model, it is protected by the patent law.
