Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a fixing structure of a photovoltaic component and a flexible steel strand. Background Art

[0002] The photovoltaic power generation system is a power generation system that directly converts solar energy into electrical energy. It can take into account both economic development and ecological protection while generating clean electricity. It is currently widely used in a variety of scenarios. It is one of the important clean energy sources to replace traditional fossil energy and has broad development prospects.

[0003] Photovoltaic power generation system is to connect photovoltaic modules through cables to form a module array, and then directly provide the electricity generated by photovoltaic modules to the power load or integrate it into the power grid through branch lines, busbars, DC / AC conversion. At present, photovoltaic systems are generally built on relatively flat ground, such as plains, deserts, saline-alkali land, etc., or built on the roof of a house, or combined with a building to form a BIPV (photovoltaic building integrated system). There is a common feature in this application environment, that is, the supporting structure of photovoltaic modules is generally rigid and easy to construct. However, in some occasions, such as undulating mountains, above the water surface, etc., the traditional structure used to fix photovoltaic modules cannot adapt, and it is necessary to provide a flexible photovoltaic module fixing installation structure to fix the photovoltaic module with the flexible steel strand.

[0004] When fixing the photovoltaic module to the flexible steel strand, the two ends of the steel strand are fixed with fixed brackets, and the photovoltaic module is fixed on the steel strand. Since the steel strand itself has a certain toughness and a certain self-weight, the load of the steel strand will also change greatly when encountering strong winds and snowy days; especially after long-term use, or when the span between the fixed brackets at both ends is large, the steel strand will be stretched and loosened, which will cause the photovoltaic module to continue to sway. If the photovoltaic module is directly fixed to the steel strand, the fixed structure will be loose and the module will fall off. In addition, due to the elongation and deformation of the steel strand, its own weight and external pressure, the middle part of the steel strand will be concave in an arc shape, which will cause the middle components in a row of components to be squeezed and damaged. In addition, when fixing the photovoltaic module to the flexible steel strand, the convenience of maintenance and replacement of the component when it fails should also be considered. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that the fixing structure of photovoltaic components and flexible steel strands is prone to loosening and the photovoltaic components are inconvenient to repair and replace, and to provide a fixing structure of photovoltaic components and flexible steel strands, which can make the fixation of photovoltaic components and flexible steel strands more reliable and facilitate the replacement of faulty components.

[0006] To achieve the above object, the present utility model adopts the following technical solutions:

[0008] Preferably, when adjacent photovoltaic modules are fixed to the steel strand, a spacer is sleeved on the steel strand between adjacent fixing structures to separate adjacent photovoltaic modules by a set distance.

[0009] More preferably, at the bottom end of the threaded portion of the claw riveting component, a barbed structure is provided, and a groove matched with the barbed structure is provided at the open end of the nut.

[0024] To further understand the purpose, structure, features and functions of the present utility model, the following is a detailed description in conjunction with the embodiments.

[0025] To make the objectives, technical solutions, and advantages of the present utility model clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present utility model with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present utility model without creative efforts fall within the scope of protection of the present utility model. It can be understood that, without conflict, some technical means described in the various embodiments herein may be mutually replaced or combined.

[0026] In the description of the present utility model, if there are terms such as "first" and "second", they are only used to distinguish the described objects and do not have any sequential or technical meaning. Thus, the objects defined with "first", "second", etc. may explicitly or implicitly include one or more of such objects. Also, words such as "one" or "a" do not indicate a quantity limitation but rather indicate the existence of at least one, and "multiple" means not less than two.

[0027] Refer to Figure 1 the structural schematic diagram of a fixing structure of a photovoltaic module and a flexible steel strand according to an embodiment of the present utility model shown in Figures 2 - 4 , the fixing structure includes an integrated fixing component 10 and a nut 20. The integrated fixing component 10 includes a fixing plate 11 with a cross-section approximately in a Z shape and a claw riveting part 12 riveted to the fixing plate as a whole. The fixing plate 11 includes a first vertical plate 110, a horizontal plate 111 perpendicular to the first vertical plate 110, and a second vertical plate 112 perpendicular to the horizontal plate 111. A riveting hole 1102 for riveting and fixing with the claw riveting part 12 is provided on the first vertical plate 110. The claw riveting part 12 includes a claw part 121 at the end, a threaded part 122, a riveting and fixing part 124, and a flange part 125. The riveting and fixing part 124 is in interference fit with the riveting hole 1102, and the flange part 125 and the claw part 121 and the threaded part 122 are arranged on both sides of the first vertical plate 110. A plurality of claw-shaped parts in a cantilever beam structure are evenly arranged at intervals in the circumferential direction on the claw part 121. The nut 20 is matched with the threaded part 122. Through holes for the steel strand to pass through are provided in the middle of the fixing component 10 and the nut 20. In a preferred embodiment, the claw part 121 is provided with 6 or 8 claws.

[0028] Refer to Figure 5As shown, when the fixing structure of the photovoltaic module and the flexible steel strand of the present utility model fixes the photovoltaic module and the steel strand, the fixing component 10 and the nut 20 are sleeved on the steel strand 200. The bottom of the frame of the photovoltaic module is placed on the cross plate 111 of the fixing plate 11, and the sides of the two side frames abut against the second vertical plate. The frame and the second vertical plate 111 are fixed by fasteners; then the nut 20 is screwed into the threaded part 122, and the nut 20 squeezes the claw part 121 to make the claws contract inward to hold the steel strand passing through it tightly, preventing it from sliding on the steel strand; Refer to Figure 1 and Figure 6 As shown, when adjacent photovoltaic modules and steel strands are fixed, a spacer 30 is sleeved on the steel strand between adjacent fixing structures to separate adjacent photovoltaic modules by a set distance. In this way, even if the middle part of the steel strand sags due to elongation, extrusion between adjacent modules can be avoided.

[0029] The fixing structure of the photovoltaic module and the flexible steel strand of the present utility model uses an integrated fixing component 10 to fix the steel cable and the photovoltaic module respectively. The photovoltaic module is not directly fixed to the steel cable. In this way, on the one hand, the installation difficulty of the module is reduced. On the other hand, even if the steel cable undergoes elongation deformation, it will not have a great impact on the fixation of the photovoltaic module; In addition, the photovoltaic module is directly connected and fixed to the fixing component. When a certain component fails and needs to be replaced, it is also convenient to replace. Through the cooperation of the nut and the claw part of the fixing component, it can be ensured that the component will not shift on the steel cable. In a preferred embodiment, refer to Figure 3 and Figure 4 , at the bottom end of the threaded part 122 of the claw riveting part 12, there is a barbed structure 123, and at the open end of the nut 20, there is a groove 203 that cooperates with the barbed structure. When the nut 20 is screwed to the bottom end of the threaded part 122, the barbed structure 123 can be caught in the groove 203 to prevent the nut from reversing and loosening, so as to better position the fixing component 10 on the steel cable.

[0030] Figure 2 As shown, this is an implementation manner of the present utility model. At one end of the photovoltaic module, a steel cable is used in cooperation with a fixing component 10 having a claw riveting part 12 to fix the photovoltaic module; when the size and specification of the module are relatively large, or in order to improve the reliability of the flexible installation system, it can also be as Figure 7 shown, at one end of the photovoltaic module, two steel cables are used in cooperation with a fixing component having two claw riveting parts 12 to fix the photovoltaic module; or more reliably, as Figure 8As shown, the Z-shaped fixing plate 11 can be a strip-shaped component that is the same length as the photovoltaic module. The entire frame of the photovoltaic module can be placed on the cross plate of the fixing plate 11. One or more claw riveting parts 12 are respectively riveted and fixed at both ends of the long strip-shaped fixing plate 11. Users can flexibly set according to the actual system installation requirements.

[0031] For the fixing structure of the photovoltaic module and the flexible steel strand of the present utility model, the photovoltaic module is fixed on the fixing component. The fixing component is fixed to the steel strand, and the fixing component is fixed at the set position of the steel strand through the cooperation of the nut with the threaded part and the claw part of the fixing component. In this way, not only can the reliable fixation of the photovoltaic module and the steel strand be ensured, but also the repair and replacement of the photovoltaic module can be facilitated; a spacer ring is used between adjacent modules to make the distance between the modules a set distance, avoiding extrusion damage between the modules.

[0032] The present utility model has been described by the above related embodiments. However, the above embodiments are only examples for implementing the present utility model. It must be pointed out that the disclosed embodiments do not limit the scope of the present utility model. On the contrary, modifications and refinements made without departing from the spirit and scope of the present utility model fall within the scope of the patent protection of the present utility model.
