Description

Technical Field

[0001] This application belongs to the field of photovoltaic power generation technology, and more specifically, relates to a photovoltaic array wind-resistant device. Background Technology

[0002] With the rapid development of solar power generation technology, photovoltaic power stations have become an important power resource in my country. Among them, mountain photovoltaic power stations, due to their higher elevation and complex terrain compared to plains, generate greater wind force when encountering strong convective weather such as strong winds than those in plains areas.

[0003] In existing technologies, photovoltaic panels are generally tilted at a certain angle to increase the area exposed to light, thereby increasing the effective area of ​​light. This results in tilted photovoltaic panels having poor wind resistance when facing strong winds. Furthermore, because photovoltaic modules are installed in rows, the area on the back of the photovoltaic panels exposed to wind is relatively large. Since photovoltaic panels are generally rigidly installed on the ground using supports, they cannot effectively buffer the external forces caused by wind when subjected to sudden strong wind loads, leading to the risk of photovoltaic panels being directly overturned.

[0023] Please refer to the following: Figures 1 to 3 The following describes a photovoltaic array wind-resistant device provided in the embodiments of this application. This utility model discloses a photovoltaic array wind-resistant device, comprising a frame 1, photovoltaic panels 2, and windbreaks 3. The frame 1 and photovoltaic panels 2 are existing technologies. Specifically, the frame 1 includes a support frame 11, multiple first columns 12, multiple second columns 13, and multiple inclined beams 14. The support frame 11 can be constructed from multiple square steel bars as in existing technologies and is used to support the photovoltaic panels 2. It should be noted that the support frame 11 is inclined, thereby increasing the effective area of ​​sunlight exposure by also incorporating the photovoltaic panels 2 fixed on the support frame 11. The first columns 12 are vertically fixed to the side of the support frame 11 near the top of the photovoltaic panels 2, and the second columns 13 are fixed to the side of the support frame 11 near the bottom of the photovoltaic panels 2. One end of the inclined beam 14 is fixed to the bottom of the first column 12, and the other end extends upwards towards the bottom of the photovoltaic panels 2 and is fixedly connected to the support frame 11. The combination of the first columns 12, second columns 13, inclined beams 14, and support frame 11 forms a stable support system.

[0024] In this embodiment, the wind deflector 3 is located on the side of the frame 1 near the top of the photovoltaic panel 2. Specifically, the wind deflector 3 is arc-shaped, with its concave surface facing the photovoltaic panel 2. The upper end of the wind deflector 3 is fixedly connected to the top of the frame 1, and the lower end of the wind deflector 3 is fixedly connected to the upper part of the frame 1. By setting the wind deflector 3, the direction of wind flow is changed, that is, the wind force is diverted by the wind deflector 3, guiding the wind force to pass above and below the wind deflector 3. It should be noted that since the upper end of the wind deflector 3 is fixed to the top of the frame 1, the wind force guided to the upper part of the wind deflector 3 will no longer affect the frame 1. The wind force guided to the lower part of the wind deflector 3 will be discharged from the lower part of the photovoltaic panel 2 through the gap between the end of the support frame 11 near the second support column and the ground. In this way, the wind force directly acting on the photovoltaic panel 2 is reduced, the risk of the photovoltaic panel 2 being overturned is reduced, and the wind resistance performance of the photovoltaic panel 2 and the frame 1 in strong wind weather is improved.

[0025] Preferably, the curvature of the wind deflector 3 is between 30 and 45 degrees. This effectively disperses wind force, reducing direct impact on the photovoltaic panel 2, while also avoiding increased wind resistance due to excessively large or small curvature, thus maximizing the wind resistance of the wind deflector 3.

[0026] In this embodiment, the windbreak 3 includes multiple baffles 31, with the ends of two adjacent baffles 31 joined together by multiple dovetail wires 32 along their length. The baffles 31 are sequentially joined together to form a complete windbreak 3, which is then installed on the frame 1. Using multiple baffles 31 for splicing facilitates the transportation and installation of the windbreak 3, and is adaptable to different arrangements of the frame 1 and photovoltaic panels 2. Preferably, the windbreak 3 is made of corrugated steel sheet. Corrugated steel sheet has a certain strength and toughness, can withstand wind force, is not easily damaged, and has a relatively low cost, is easy to obtain and install, further improving the practicality and economy of the windbreak 3.

[0027] In this embodiment, multiple reinforcing plates 4 are fixedly mounted at intervals on the concave surface of the windbreak plate 3. The reinforcing plates 4 have an arc-shaped structure that matches the concave surface of the windbreak plate 3. Therefore, when wind impacts the windbreak plate 3, the reinforcing plates 4 and the windbreak plate 3 share the wind force to disperse stress. In other words, the reinforcing plates 4 enhance the structural strength of the windbreak plate 3, making it less prone to deformation or damage under strong winds, further improving the wind resistance and service life of the windbreak plate 3, and ensuring the safe and stable operation of the photovoltaic array.

[0028] In this embodiment, a slider 5 is slidably fitted on the outer side of each first column 12. The bottom ends of multiple reinforcing plates 4 correspond one-to-one with the multiple first columns 12 and are engaged with the slider 5 on each first column 12. A wing bolt 52 is screwed onto one side of the slider 5, and one end of the wing bolt 52 passes through the side wall of the slider 5 and abuts against the first column 12. During implementation, the operator slides the slider 5 to a suitable position, then tightens the wing bolt 52 to fix the slider 5 on the first column 12, and then engages the bottom end of the reinforcing plate 4 with the slider 5.

[0029] Specifically, the upper part of the slider 5 is recessed with an annular groove 51, and the bottom end of the reinforcing plate 4 is provided with a U-shaped groove 41. The inner wall of the U-shaped groove 41 is engaged with the outer wall of the annular groove 51. By setting the engaging structure of the annular groove 51 and the U-shaped groove 41, the connection and disassembly of the reinforcing plate 4 and the slider 5 can be quickly realized, which facilitates installation and maintenance, improves work efficiency, and ensures the strength and stability of the connection.

[0030] In this embodiment, the open end of the U-shaped groove 41 is provided with a rod 6. One end of the rod 6 passes sequentially through the two side walls of the open end of the U-shaped groove 41 and is screwed with a nut 7. In practice, after the U-shaped groove 41 is snapped onto the annular groove 51, the rod 6 is inserted and the nut 7 is tightened to better fix the reinforcing plate 4 and the slider 5. When wind force is applied, the fixing effect of the rod 6 and the nut 7 enhances the connection strength between the U-shaped groove 41 and the annular groove 51, preventing the reinforcing plate 4 from falling off.

[0031] In the specific implementation of this utility model, firstly, according to the actual site conditions, multiple baffles 31 are spliced ​​together to form a windbreak 3 of a preset length using dovetail wires 32. The windbreak 3 is then bent into an arc shape with an arc of about 30 to 45 degrees. Then, multiple reinforcing plates 4 are placed at intervals on the concave surface of the windbreak 3 (at this time, multiple windbreaks 3 correspond to multiple first columns 12). Then, the windbreak 3 and the reinforcing plates 4 are fixed together with dovetail wires 32. Next, the top of the windbreak 3 is fixed to the top of the frame 1 (in actual operation, any one of the existing technologies, such as dovetail wires 32, rigid cable ties, or iron wire, can be used to fix the windbreak 3 to the frame 1, which will not be described in detail here). At this time, the concave surface of the wind deflector 3 faces the photovoltaic panel 2. Then, the bottom end of the reinforcing plate 4 is connected to the slider 5 through the snap-fit ​​structure of the annular groove 51 and the U-shaped groove 41. Next, the insert rod 6 is passed through the side wall of the U-shaped groove 41 and screwed with the nut 7 to further fix the reinforcing plate 4 and the slider 5, enhance the connection strength, and prevent the reinforcing plate 4 from falling off.

[0032] When encountering strong convective weather such as strong winds, the windbreak 3 installed on the side of the frame 1 near the top of the photovoltaic panel 2 comes into play. The windbreak 3 diverts the wind force, guiding it to pass above and below the windbreak 3, thereby reducing the wind force directly acting on the photovoltaic panel 2, lowering the risk of the photovoltaic panel 2 being overturned, significantly improving the wind resistance performance of the photovoltaic array in strong wind weather, and ensuring the normal operation of the photovoltaic power station.

[0033] It is understood that the parts in the above embodiments can be freely combined or deleted to form different combined embodiments. The specific contents of each combined embodiment will not be repeated here. After this description, it can be considered that the present utility model specification has recorded each combined embodiment and can support different combined embodiments.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
