Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel fixing devices, and in particular to a flexible photovoltaic panel fixing fixture for cement roofs that does not require drilling. Background Technology

[0002] Solar photovoltaic (PV) power generation systems are power generation systems that use the photovoltaic effect of solar cell semiconductor materials to directly convert solar radiation energy into electrical energy. With the development and promotion of PV technology, installing PV panels on rooftops has become a trend.

[0003] Currently, photovoltaic panels are generally installed on cement roofs. Typically, holes are drilled in the cement roof to install brackets, and then the photovoltaic panel structure is installed onto the brackets. This fixing method, which involves drilling holes in the cement roof and using bolts to install the photovoltaic panels, places certain requirements on the load-bearing capacity of the cement roof.

[0004] For some cement roofs that have been built for a long time, the load-bearing capacity of the roof has decreased due to its age. Drilling holes in the roof can easily cause damage to the building roof. Obviously, it is not suitable to fix the photovoltaic panels by drilling bolts. Therefore, there is a need to provide a tooling for fixing photovoltaic panels on cement roofs without drilling. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, which is unsuitable for cement roofs and causes serious damage to the roof and low safety when installing photovoltaic panels by drilling holes in the roof. Therefore, this utility model provides a flexible photovoltaic panel fixing fixture for cement roofs that does not require drilling.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A flexible photovoltaic panel fixing fixture for cement roof without drilling includes an mounting plate and a fixing component. The fixing component is glued to the roof, the mounting plate is fixed to the fixing component, and the photovoltaic panel is installed on the side of the mounting plate away from the fixing component.

[0008] The fastener includes an arched support and a flat plate connecting part. The arched support is connected to the flat plate connecting part, and the flat plate connecting part is glued to the roof. The upper end face of the arched support is a straight section, and the mounting plate is fixed on the straight section.

[0009] Preferably, the arched support includes a first bent section, a straight section, and a second bent section connected in sequence. The first bent section and the second bent section are symmetrically distributed on both sides of the straight section and are respectively connected to the flat plate connecting section.

[0010] Preferably, the flat plate connecting portion includes a recessed section and a raised section, and the recessed section and the raised section are alternately connected.

[0011] Preferably, the two ends of the flat plate connecting part are respectively provided with recessed sections, and the side of the recessed section away from the protruding section is connected to the arched support part.

[0012] Preferably, the fastener includes multiple arched support portions, and adjacent arched support portions are connected by a flat plate connecting portion.

[0013] Preferably, the arched support portions of the same fastener are parallel to each other and are distributed at equal intervals.

[0014] Preferably, there are multiple fasteners, and each fastener is distributed in an array.

[0015] Preferably, the fasteners comprise multiple rows, with the fasteners in the same row distributed at equal intervals and parallel to each other.

[0016] Preferably, the photovoltaic panel array is distributed on a mounting plate.

[0017] Preferably, the mounting plate is glued and fixed to the arched support.

[0018] Compared with the prior art, the present invention has the following advantages:

[0019] (1) In this scheme, the fastener is placed on the roof, and the flat plate connecting part of the fastener is fixed on the roof by adhesive. The photovoltaic panel is fixed to the mounting plate, and the mounting plate is placed on the arched support part of the fastener. The flat section at the upper end of the arched support part contacts the mounting plate and connects with the mounting plate, thus completing the installation of the photovoltaic panel on the roof.

[0020] The fasteners are glued to the roof via a flat plate connector, avoiding drilling into the roof and compromising its load-bearing capacity, thus ensuring the safety of the photovoltaic panel installation. The large contact area between the flat plate connector and the roof guarantees a reliable connection between the fasteners and the roof. The arched support of the fastener connects to the flat plate connector and fixes the mounting plate to the straight section at the top of the arched support, ensuring sufficient spacing between the photovoltaic panels and the roof. Ventilation holes are provided between the fasteners, the roof, and the mounting plate to ensure heat dissipation and efficient solar energy utilization of the photovoltaic panels.

[0021] (2) The flat plate connection part of the fastener in this solution that contacts the roof includes alternating recessed sections and raised sections. The recessed sections are glued to the roof, and the raised sections are more adaptable to changes in terrain according to the deformation of the roof, which improves the stability and reliability of the flat plate connection part and has a wider range of applications.

[0033] Example 1

[0034] like Figures 1 to 3 As shown, this embodiment provides a flexible photovoltaic panel fixing fixture for cement roofs without drilling, including a mounting plate 1 and a fixing member 2. The fixing member 2 is glued to the roof, the mounting plate 1 is fixed to the fixing member 2, and the photovoltaic panel is installed on the side of the mounting plate 1 away from the fixing member 2.

[0035] The fastener 2 includes an arched support 21 and a flat plate connecting part 22. The arched support 21 is connected to the flat plate connecting part 22, and the flat plate connecting part 22 is glued to the roof. The upper end face of the arched support 21 is a straight section, and the mounting plate 1 is fixed on the straight section.

[0036] Working principle: Place the fixing part 2 on the roof, fix the flat plate connecting part 22 of the fixing part 2 to the roof with adhesive, fix the photovoltaic panel to the mounting plate 1, place the mounting plate 1 on the arched support part 21 of the fixing part 2, and connect the mounting plate 1 through the straight section at the upper end of the arched support part 21, thus completing the installation of the photovoltaic panel on the roof.

[0037] The fastener 2 is glued to the roof via the flat plate connecting part 22, avoiding drilling holes in the roof and compromising its load-bearing capacity, thus ensuring the safety of the photovoltaic panel installation. The flat plate connecting part 22 also provides a large contact area with the roof, ensuring reliable connection between the fastener 2 and the roof. The arched support part 21 of the fastener 2 connects to the flat plate connecting part 22, and the mounting plate 1 is fixed to the straight section at the upper end of the arched support part 21, ensuring sufficient spacing between the photovoltaic panel and the roof. Ventilation holes are provided between the fastener 2, the roof, and the mounting plate 1 to ensure heat dissipation and efficient light energy utilization of the photovoltaic panel.

[0038] Among them, such as Figure 3 and Figure 4As shown, the arched support 21 includes a first bent section 211, a straight section 212, and a second bent section 213 connected in sequence. The first bent section 211 and the second bent section 213 are symmetrically distributed on both sides of the straight section 212 and are respectively connected to the flat plate connecting part 22.

[0039] The straight section 212 is supported by the first bending section 211 and the second bending section 213, maintaining a certain distance from the roof. The straight section is used to ensure the contact area with the mounting plate, thereby improving the stability of the structure and the reliability of fixing the mounting plate to the photovoltaic panel.

[0040] Preferred implementation methods, such as Figure 3 and Figure 4 As shown, the flat plate connecting part 22 includes a recessed section 221 and a raised section 222, which are alternately connected.

[0041] The flat plate connecting part 22 has a recessed section 221 at each end, and the side of the recessed section 221 away from the protruding section 222 is connected to the arched support part 21.

[0042] The flat plate connection part that contacts the roof includes alternating recessed sections and raised sections. The recessed sections are glued to the roof, while the raised sections have a stronger ability to adapt to changes in terrain according to the deformation of the roof, thus improving the stability and reliability of the flat plate connection and making it more widely applicable.

[0043] Specifically, the fastener 2 includes multiple arched support portions, which are connected by flat plate connectors. The arched support portions of the same fastener 2 are parallel to each other and evenly spaced. The presence of multiple arched support portions on a single fastener 2 improves the support surface of the fastener to the mounting plate, ensuring reliable fastening.

[0044] Furthermore, such as Figure 1 and Figure 2 As shown, there are multiple fasteners 2, arranged in an array. The fasteners 2 comprise multiple rows, with equal spacing between fasteners 2 within the same row, and the fasteners 2 within the same row are parallel to each other. The photovoltaic panel array is distributed on the mounting plate 1.

[0045] Specifically, the mounting plate 1 is glued and fixed to the arched support 21. This improves the convenience and efficiency of connecting the mounting plate 1 to the fasteners 2, while the fasteners 2, which are arranged in an array below the mounting plate, ensure the stability and reliability of the mounting plate on the fasteners.

[0046] Furthermore, the fastener 2 can be made of PVC board or composite material, which is lightweight and high-strength, reducing the load on the roof and ensuring the stability and reliability of the fixed support for the mounting plate 1.

[0047] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
