Description

Technical Field

[0001] This utility model belongs to the technical field of flexible curved photovoltaic canopy building materials, specifically a BIPV curved photovoltaic canopy panel structure. Background Technology

[0002] Currently, all known curved canopy photovoltaic retrofit installation solutions on the market employ on-site construction using structural adhesives to bond flexible photovoltaic modules. This process is difficult to implement, and the installation quality cannot be guaranteed. Furthermore, the complex on-site construction environment and inconsistent skill levels lead to frequent installation problems. The flexible photovoltaic modules are easily damaged during construction, causing quality and safety hazards. Additionally, the construction efficiency is low, installation consistency is poor, and the aesthetics fail to meet the design requirements of BIPV (Building Integrated Photovoltaics). Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies and provide a BIPV curved photovoltaic canopy panel structure.

[0004] The technical problem solved by this utility model is achieved through the following technical solution:

[0005] A BIPV curved photovoltaic canopy panel structure includes purlins, curved water channels, longitudinal pressure plates, and flexible photovoltaic panels;

[0006] A single purlin is installed horizontally, and four purlins are installed at intervals in the longitudinal direction;

[0007] A single curvature water tank is set along the longitudinal direction. In the longitudinal direction, two curvature water tanks are connected to each other to form a set of curvature water tanks. Each set of curvature water tanks forms an arc-shaped water tank. N sets of curvature water tanks are set at equal intervals in the transverse direction. The two curvature water tanks in each set of curvature water tanks are connected to the purlins at the bottom by bolts.

[0008] The curved water tank has a channel in the middle, and wing plates are provided on both sides of the top of the channel. The longitudinal pressure plate is installed on the wing plate of the curved water tank by rivets. A boss is provided on one side of the bottom of the longitudinal pressure plate, and the rivet is located at the boss. An installation space is formed between the longitudinal pressure plate and the wing plate. The edge of the flexible photovoltaic panel is pressed into the installation space. A flexible photovoltaic panel is installed between two horizontally adjacent curved water tanks in each group.

[0009] In the above technical solution, the purlins are made of channel steel.

[0010] In the above technical solution, the bolt is a U-bolt.

[0011] In the above technical solution, two flange plates are provided at the bottom of each curved water tank, and four mounting holes are provided on each flange plate. Each flange plate is connected to a purlin by two U-bolts.

[0012] In the above technical solution, weather-resistant adhesive is filled at the joint of two longitudinally adjacent flexible photovoltaic panels, and a horizontal pressure plate is installed on the top.

[0013] In the above technical solution, windproof cover plates are installed at the outer ends of two horizontally adjacent curved water tanks in each group to ensure the wind resistance strength of the edges and eaves.

[0014] The advantages and beneficial effects of this utility model are as follows:

[0015] This utility model's BIPV curved photovoltaic canopy panel structure adopts a prefabricated product design, resulting in high installation efficiency and standardized production, avoiding damage to flexible components during construction. The fully prefabricated installation is superior to adhesive bonding, providing greater stability and strength. It also provides better support for the flexible components, preventing collapse and damage during prolonged use, while also avoiding localized dust accumulation and hot spots.

[0023] The present invention will be further described in detail below through specific embodiments. The following embodiments are only descriptive and not limiting, and should not be used to limit the protection scope of the present invention.

[0024] This utility model designs a BIPV curved photovoltaic canopy panel structure, see attached document. Figure 1 -Appendix Figure 6It includes purlin 1, curved water channel 2, longitudinal pressure plate 3, transverse pressure plate 4, flexible photovoltaic panel 5, and windproof cover plate 6.

[0025] A single purlin 1 is arranged in the transverse direction, and four purlins 1 are arranged at intervals in the longitudinal direction. Preferably, the purlins are made of channel steel.

[0026] A single curvature water tank 2 is arranged longitudinally. In the longitudinal direction, two curvature water tanks 2 are connected to form a set of curvature water tank pairs, and each set of curvature water tank pairs forms a large arc water tank. N sets of curvature water tank pairs are arranged at equal intervals in the transverse direction (the number of N is not limited and depends on the actual needs). Figure 1 The image shows three sets of curved water channels. In each set, two curved water channels are connected to the bottom purlins 1 by bolts (i.e., the front curved water channel 2 of each set is fixedly connected to the front two purlins of the four purlins, and the rear curved water channel 2 is fixedly connected to the rear two purlins of the four purlins. Here, "front" and "rear" refer to front and rear along the longitudinal direction). Furthermore, the bolts are U-bolts 7, and two flange plates 21 are provided at the bottom of each curved water channel 2 (see Appendix). Figure 3 and attached Figure 4 Each flange 21 has four mounting holes, and each flange is connected to a purlin 1 by two U-bolts 7 (see Appendix). Figure 5 ).

[0027] The structure of the curved water tank 2 is as follows: (See Appendix) Figure 6 The middle part of the curved water trough 2 is the channel 22, which serves as a water guide for rainwater. Wing plates 23 are provided on both sides of the top of the channel 22, and the wing plates 23 are used to connect with the longitudinal pressure plate 3.

[0028] The longitudinal pressure plate 3 is installed on the wing plate 23 of the curved water tank 2 by rivets 8. A boss 31 is provided on one side of the bottom of the longitudinal pressure plate 3, and the rivets 8 are located at the boss 31. After the longitudinal pressure plate 31 and the wing plate 23 are riveted together, an installation space 100 is formed between the longitudinal pressure plate 3 and the wing plate 23. The edge of the flexible photovoltaic panel 5 is pressed into the installation space 100, so that a flexible photovoltaic panel 5 is installed between each set of two horizontally adjacent curved water tanks 2.

[0029] The joint between two longitudinally adjacent flexible photovoltaic panels 5 is filled with weather-resistant sealant 9 (see Appendix). Figure 3 ), and install a horizontal pressure plate 4 on the upper part (see appendix). Figure 4 ).

[0030] Furthermore, windproof cover plates 6 are installed at the outer ends of two laterally adjacent curved water tanks 2 in each group (see Appendix). Figure 3 and attached Figure 5This ensures the wind resistance of the edges and eaves. The windproof cover 6 can be connected to the outer end of the curved water trough 2 by bolts or by structural adhesive.

[0031] Furthermore, the flexible photovoltaic panel 5 can utilize traditional crystalline silicon flexible modules, copper indium gallium selenide thin-film modules, third-generation perovskite modules, etc., offering strong versatility and scalability. The main installation structure can be constructed from various materials such as carbon steel, aluminum alloy, and fiberglass polyurethane to meet the needs of different scenarios.

[0032] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0033] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0034] The present invention has been described above by way of example. It should be noted that, without departing from the core of the present invention, any simple modifications, alterations or other equivalent substitutions that can be made by those skilled in the art without creative effort fall within the protection scope of the present invention.
