Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation, in particular to a flexible mounting bracket capable of achieving angle adjustment of photovoltaic components. Background Art

[0002] Photovoltaic power generation systems are power generation systems that directly convert solar energy into electrical energy. They can balance economic development and ecological protection while generating clean electricity. They are currently widely used in a variety of scenarios. They are one of the important clean energy sources to replace traditional fossil energy and have broad development prospects.

[0003] A photovoltaic power generation system connects photovoltaic modules via cables to form an array. The electricity generated by the modules is then fed directly to loads or fed into the power grid through branch lines, busbars, and DC / AC conversion. Current photovoltaic systems are typically constructed on relatively flat terrain, such as plains, deserts, and saline-alkali lands, on rooftops, or integrated with buildings to form BIPV (Building Integrated Photovoltaic) systems. These applications share a common characteristic: the supporting structures for the photovoltaic modules are generally rigid, making construction relatively easy. However, in some locations, such as mountainous terrain or above water, traditional structures for securing photovoltaic modules are inadequate, necessitating a flexible mounting structure for photovoltaic modules.

[0004] Flexible photovoltaic module mounting structures primarily utilize steel strands for installation. The strands are secured at both ends with brackets, and the photovoltaic modules are fixed to the strands. Due to the inherent toughness and deadweight of the strands, the load on the strands can fluctuate significantly during windy or snowy conditions. Furthermore, over time, or when the span between the brackets is large, the strands can become increasingly loose, causing the photovoltaic modules to sway continuously, further exacerbating the loosening of the strands. Furthermore, most current flexible photovoltaic module mounting brackets make it difficult to adjust the module's mounting angle, preventing them from maximizing their power generation capacity. Therefore, the design of flexible photovoltaic module mounting brackets must balance reliable module installation with the ability to flexibly adjust the module's mounting angle to maximize its power generation efficiency.

[0028] Reference Figure 1 The structure diagram of a flexible mounting bracket that can adjust the angle of a photovoltaic module according to an embodiment of the present invention is shown. The flexible mounting bracket includes a first steel column 10, a first end pile seat 14, a second steel column 20 and a second end pile seat 24. The first steel column 10 includes a first base 12 and a first support column 11, and the second steel column 20 includes a second base 22 and a second support column 21; the first base 12, the first end pile seat 14, the second base 22 and the second end pile seat 24 are all fixed on a concrete base 100.

[0029] The photovoltaic module (not shown) is fixed on the steel strand 30. One end of the steel strand is fixed to the second support column 21, and the other end is connected to the first end pile seat 14 after passing through the movable routing roller 16 on the first support column 21 and the pulley 15 above it. The end portion is wound around the rotating shaft of the first motor 17.

[0030] Reference Figure 2 and Figure 3As shown, a slide groove 13 is provided on the upper part of the first support column 21, and a movable routing roller 16 is arranged in the slide groove 13; the slide groove 13 includes a circular hole groove 131 with a larger diameter at the upper part and a long groove 132 connected to the circular hole groove 131, and the width of the long groove 132 is smaller than the diameter of the circular hole groove 131; the movable routing roller 16 includes a thick-diameter shaft portion 161 with a larger diameter in the middle part and thin-diameter shaft portions 162 symmetrically arranged on both sides, the diameter of the thick-diameter shaft portion 161 is smaller than the diameter of the circular hole groove 131 and larger than the width of the long groove 132, and the diameter of the thin-diameter shaft portion 162 is smaller than the width of the long groove 132. The steel strands 30 that secure the photovoltaic modules are passed around the thick-diameter shaft 161 and then to the pulley 15 above. The thin-diameter shafts 162 on both sides are connected to lifting wire ropes 19, one end of which is connected to the thin-diameter shaft 162 of the movable routing roller 16, and the other end is fixedly wound around a rotating shaft of the dual-axis motor 32. The dual-axis motor drives the lifting wire ropes 19 on one side to rise and fall synchronously through the two output shafts. In a preferred embodiment, the middle portion of the thick-diameter shaft 161 and the thin-diameter shaft 162 are both provided with rope grooves 164 to facilitate the positioning of the steel strands and wire ropes. In another preferred embodiment, flanges 163 are provided at both ends of the movable routing roller 16 to prevent the lifting wire ropes 19 from falling off the movable routing roller 16.

[0031] In the flexible mounting bracket of the present invention, one end of the steel strand that fixes the photovoltaic module is fixed on the second support column, and the other end is adjustable up and down on the first support column. When it is necessary to adjust the light receiving angle of the photovoltaic module, the first motor 17 and the dual-axis motor 32 can drive the steel strand 30 and the lifting wire rope 19 to move so that the fixed point of the steel strand that fixes the photovoltaic module on the first support column is moved. As shown in the figure, for example, if it is necessary to move the fixed point upward, even if the movable routing roller 16 moves upward along the chute 13, the first motor 17 works to pull the steel strand 30 for winding, while the dual-axis motor 32 works to release the wire and release the lifting wire rope 19. When the movable routing roller 16 moves to the appropriate position, the two motors stop working, causing the movable routing roller 16 to remain in this position. When it is necessary to move the movable routing roller 16 up and down along the chute 13, the working process of the two motors is exactly the opposite.

[0032] In a preferred embodiment, when the movable routing roller 16 moves to an appropriate position and needs to be fixed, the steel strand and the lifting wire rope can be fixed by a cable fixing structure 33, and the cable fixing structure 33 includes a claw component 331 and a nut 332; in a preferred embodiment, the claw component 331 and the nut 332 are made of stainless steel. Figure 4 The claw part 331 includes a claw 3311, a threaded portion 3312 and a flange portion 3313. The middle portion of the claw part 331 is a through hole for the cable to pass through. Figure 1As shown in the example, the other end of the steel strand 30 is connected to the first end pile seat 14, and the first motor 17 is arranged in the first end pile seat 14; Figure 5 At this time, the claw component 331 and the nut 332 can be set on the steel strand 30 inside the first end pile seat 14. When the motor is working to move the movable routing roller 16 to the appropriate position, the flange of the claw component 331 is pressed against the inner wall of the first end pile seat 14, and then the nut 332 is assembled with the threaded portion 3312. The claw portion 3311 is squeezed inward and tightened by the nut 332, thereby fixing the steel strand 30 to the first end pile seat 14. Similarly, refer to Figure 3 The dual-axis motor is arranged in the first base 12, and the lifting wire rope 19 can also be fixed to the first base 12 through the cable fixing structure 33; in this way, the pulling force of the steel strand or steel wire rope on the motor rotating shaft can be reduced or avoided when the motor is not working, thereby avoiding deformation of the rotating shaft after long-term operation.

[0033] In the present invention, the first end pile seat 14 is arranged at a distance from the first steel column 10. Similarly, the second end pile seat 24 is also arranged at a distance from the second steel column 20. A cable 23 is connected between the top end of the second steel column 20 and the second end pile seat 24. In this way, the first end pile seat 14 forms a cable structure with the first steel column 10, and the second end pile seat forms a cable structure with the second steel column 20, which can significantly improve the overall strength of the flexible mounting bracket.

[0034] In another preferred embodiment, a tension sensor 18 is provided on the steel noose 30. When the tension sensor 18 senses that the tension of the steel noose 30 is lower than a predetermined value, it means that the steel noose 30 is in a relaxed state. At this time, the first motor 17 can start working according to the signal of the tension sensor 18, tighten the steel noose 30, and put the steel noose 30 in a tensioned state to prevent the components thereon from swinging.

[0035] In addition, it should be understood that in order to maintain the fixed stability of the photovoltaic modules, a row of photovoltaic modules may correspond to at least two groups of the above-mentioned first steel columns 10, first end pile seats 14, second steel columns 20 and second end pile seats 24.

[0036] The utility model is a flexible mounting bracket that can realize adjustable angle of photovoltaic components. One end of the steel rope for fixing the photovoltaic components is fixed, and the other end is position-adjustable. The height of the other end can be conveniently adjusted by a motor, a movable routing roller, and a lifting wire rope to achieve different light-receiving angles of the photovoltaic components and improve their power generation efficiency. In addition, by arranging a tension sensor, when the steel rope is loose, it can be tightened in time to avoid shaking of the components.

[0037] The present invention has been described with reference to the above embodiments. However, these embodiments are merely exemplary embodiments of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and improvements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
