Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a wind-resistant device for photovoltaic supports. Background Technology

[0002] The main purpose of installing wind-resistant devices on photovoltaic (PV) brackets is to ensure the stability of the PV brackets and PV modules in harsh wind environments by fixing their strength and dispersing the effects of wind, thus preventing direct damage to the PV brackets from strong winds.

[0003] When existing photovoltaic (PV) panels encounter strong winds, the PV mounting system pushes the PV panels to keep them horizontal with the direction of the strong wind, thereby reducing the windward surface of the PV panels and reducing the pressure of the strong wind. However, PV panels are usually installed inside a rectangular mounting plane. When strong winds come into contact with the mounting plane, air vortices are easily generated on the rectangular contact surface of the mounting plane. These vortices will create a pressure field near the mounting plane, causing the mounting plane to have to withstand additional wind force, which is not conducive to improving the wind resistance performance of the PV mounting system.

[0004] Therefore, this application provides a wind-resistant device for photovoltaic brackets to meet the requirements. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and propose a wind-resistant device for photovoltaic supports.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a photovoltaic support wind-resistant device, comprising a photovoltaic support body, and further comprising:

[0007] A wind-resistant component is placed on top of the photovoltaic support body. The wind-resistant component includes an installation frame set on top of the photovoltaic support body. Main windbreaks are provided on all four sides of the installation frame. The main windbreaks have an arc-shaped structure.

[0008] A reinforcement component, which is placed inside the wind-resistant component and is used to increase the rigidity of the main wind deflector, the reinforcement component including a support frame connected to the inner wall of the main wind deflector, the support frame being a trident-shaped structure.

[0009] Furthermore, a strip slider is connected to the side of the support frame near the mounting frame, and a strip rail is connected to the side of the support frame near the strip slider. The strip slider is slidably connected to the mounting frame through the strip rail.

[0010] The advantages of adopting the above-mentioned further solution are: the main wind deflector and the supporting frame can be quickly installed on the mounting frame, and at the same time, the main wind deflector can be easily removed and replaced, which helps to improve the maintenance efficiency of the main wind deflector.

[0011] Furthermore, both sides of the strip slider are connected to connectors.

[0012] The beneficial effect of adopting the above-mentioned further solution is that it keeps the strip slider stable on the mounting frame, ensuring the stability of the main wind deflector during use.

[0013] Furthermore, the bottom of the photovoltaic support body is connected to a concrete foundation, and secondary windbreaks are provided on both sides of the concrete foundation.

[0014] The beneficial effects of adopting the above-mentioned further solutions are: reducing the risk of the support being overturned by strong winds, which helps to improve the wind resistance of the photovoltaic support body. At the same time, the secondary windbreaks shield the connection between the photovoltaic support body and the concrete foundation and part of the photovoltaic support body from both sides, which helps to improve the stability of the connection between the photovoltaic support body and the concrete foundation.

[0015] Furthermore, an arc-shaped slider is connected to the side of the two auxiliary wind deflectors closest to the concrete foundation, and an arc-shaped slide rail is connected to the side of the concrete foundation closest to the arc-shaped slider. The auxiliary wind deflectors are movably connected to the concrete foundation through the arc-shaped slide rail and the arc-shaped slider.

[0016] The beneficial effect of adopting the above-mentioned further solution is that it ensures that the secondary wind deflector is always aligned with the wind direction, and that the maximum height of the secondary wind deflector is lower than the lowest position when the mounting frame is tilted.

[0017] Furthermore, each of the two arc-shaped sliders has a side plate connected to its adjacent side, and bolts are connected to the side plate. The two arc-shaped sliders are fixed to each other by the side plates and bolts.

[0018] The beneficial effect of adopting the above-mentioned further solution is that it facilitates fixing the arc-shaped slider on the arc-shaped slide rail, thereby improving the installation and maintenance efficiency of the arc-shaped slider.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] 1. By setting up wind-resistant components, when strong winds come into contact with the main windbreak plate, the main windbreak plate guides the strong winds through the installation frame and photovoltaic panels through its arc structure, reducing the positive pressure on the windward side. At the same time, the main windbreak plate disrupts the formation of vortices, solving the problem that vortices form a pressure field near the installation plane, causing the installation plane to bear additional wind force, which is beneficial to improving the wind resistance performance of the photovoltaic bracket.

[0021] 2. This utility model, by setting up a reinforcing component, welds the support frame to the inside of the main windshield. The support frame adopts a three-pronged structure, which can provide support from multiple points inside the main windshield, thereby improving the rigidity of the main windshield, preventing it from deforming due to excessive force, and thus ensuring the stability of the main windshield during use.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] like Figures 1-6As shown, this utility model provides a technical solution: a photovoltaic support wind-resistant device, including a photovoltaic support body 1, and further including:

[0034] like Figures 1-4 As shown, the wind-resistant component 2 is placed on top of the photovoltaic support body 1. The wind-resistant component 2 includes an installation frame 21 set on top of the photovoltaic support body 1. Main windbreaks 22 are provided on all four sides of the installation frame 21. The main windbreaks 22 have an arc-shaped structure.

[0035] like Figures 1-4 As shown, the reinforcement component 3 is placed inside the wind-resistant component 2 and is used to increase the rigidity of the main windbreak 22. The reinforcement component 3 includes a support frame 31 connected to the inner wall of the main windbreak 22. The support frame 31 has a triangular structure. The mounting frame 21 is fixed to the top of the photovoltaic bracket body 1 using bolts 28. The photovoltaic panel is installed inside the mounting frame 21. When strong wind comes into contact with the main windbreak 22, due to the cross-section and arc structure of the main windbreak 22, the main windbreak 22 guides the strong wind over the mounting frame 21 and the photovoltaic panel, reducing the positive pressure on the windward side. Meanwhile, the main wind deflector 22 disrupts the formation of vortices, allowing strong winds to flow more smoothly. This solves the problem that vortices would generate a pressure field near the installation plane, causing the installation plane to have to withstand additional wind force. This is beneficial to improving the wind resistance of the photovoltaic bracket. Furthermore, by welding the support frame 31 inside the main wind deflector 22, and since the support frame 31 has a three-pronged structure, the support frame 31 supports the main wind deflector 22 from multiple points inside, improving the rigidity of the main wind deflector 22, preventing the main wind deflector 22 from deforming due to excessive force, and ensuring the stability of the main wind deflector 22 during use.

[0036] Furthermore, such as Figure 3 As shown, a strip slider 32 is connected to the side of the support frame 31 near the mounting frame 21, and a strip rail 33 is connected to the side of the support frame 31 near the strip slider 32. The strip slider 32 is slidably connected to the mounting frame 21 through the strip rail 33. By welding the strip rail 33 to the mounting frame 21 and welding the strip slider 32 to the support frame 31, the strip slider 32 is pushed to slide along the strip rail 33, thereby quickly installing the main wind deflector 22 and the support frame 31 onto the mounting frame 21. At the same time, it facilitates the removal and replacement of the main wind deflector 22, which helps to improve the maintenance efficiency of the main wind deflector 22.

[0037] Furthermore, such as Figure 3As shown, both sides of the strip slider 32 are connected to connectors 34. By placing the connectors 34 on both sides of the strip slider 32, the connectors 34 are fixed to the strip slider 32 by using threaded post and nut. The strip slide rail 33 is snapped into the inside of the strip slider 32, so that the strip slider 32 remains stable on the mounting frame 21, ensuring the stability of the main wind deflector 22 during use.

[0038] Furthermore, such as Figure 5 As shown, the bottom of the photovoltaic support body 1 is connected to a concrete foundation 23. Auxiliary windbreaks 24 are provided on both sides of the concrete foundation 23. The photovoltaic support body 1 is fixed to the top of the concrete foundation 23 by using threaded posts and nuts. The concrete foundation 23 increases the ground weight of the bottom of the photovoltaic support body 1 by its own weight, reducing the risk of the support being overturned by strong winds and improving the wind resistance of the photovoltaic support body 1. At the same time, the auxiliary windbreaks 24 shield the connection between the photovoltaic support body 1 and the concrete foundation 23 from both sides, protecting the connection between the photovoltaic support body 1 and the concrete foundation 23 and part of the photovoltaic support body 1, which helps to improve the stability of the connection between the photovoltaic support body 1 and the concrete foundation 23.

[0039] Furthermore, such as Figure 6 As shown, two auxiliary wind deflectors 24 are connected to an arc-shaped slider 26 on the side near the concrete foundation 23. An arc-shaped slide rail 25 is connected to the side of the concrete foundation 23 near the arc-shaped slider 26. The auxiliary wind deflectors 24 are movably connected to the concrete foundation 23 through the arc-shaped slide rail 25 and the arc-shaped slider 26. By splicing and fixing the two arc-shaped slide rails 25 to the concrete foundation 23, the arc-shaped slider 26 slides on the arc-shaped slide rail 25. When the auxiliary wind deflectors 24 come into contact with strong winds from different directions, the arc-shaped slide rail 25 and the arc-shaped slider 26 cooperate to allow the auxiliary wind deflectors 24 to rotate along the wind direction, thereby ensuring that the auxiliary wind deflectors 24 always remain aligned with the wind direction, and that the maximum height of the auxiliary wind deflectors 24 is lower than the lowest position when the mounting frame 21 is tilted.

[0040] Furthermore, such as Figure 6 As shown, each of the two arc-shaped sliders 26 has a side plate 27 connected to its adjacent side. Bolts 28 are connected to the side plate 27. The two arc-shaped sliders 26 are fixed to each other by the side plate 27 and the bolts 28. By splicing the two arc-shaped sliders 26 together and using the bolts 28 and nuts, it is easy to fix the arc-shaped sliders 26 to the arc-shaped slide rail 25, which helps to improve the installation and maintenance efficiency of the arc-shaped sliders 26.

[0041] Working principle: such as Figures 1-6As shown, when the external detection device detects strong winds, the control system activates the hydraulic device on the photovoltaic support body 1, pushing the mounting frame 21 to rotate along the photovoltaic support body 1, keeping the mounting frame 21 and the photovoltaic panel horizontal with respect to the direction of the strong wind. When the strong wind comes into contact with the main windbreak plate 22 on the mounting frame 21, the main windbreak plate 22, through its own arc structure, guides the strong wind over the mounting frame 21 and the photovoltaic panel, reducing the positive pressure on the windward side and also disrupting the formation of vortices, allowing the strong wind to flow more smoothly. At this time, the support frame 31 supports the main windbreak plate 22 from multiple internal points, increasing the rigidity of the main windbreak plate 22. Simultaneously, the secondary windbreak plate 24 comes into contact with the strong wind, and the secondary windbreak plate 24 is subjected to force. The curved slider 26 is rotated along the curved slide rail 25, making the secondary wind deflector 24 aligned with the wind direction. This allows the secondary wind deflector 24 to block strong winds from the front, reducing the stress on the connecting components between the photovoltaic support body 1 and the concrete foundation 23, and reducing some of the positive pressure on the photovoltaic support body 1. When maintenance is required after the strong wind subsides, the connector 34 is separated from the strip slider 32, allowing the strip slider 32 to slide along the strip slide rail 33. After replacing the main wind deflector 22 and the support frame 31, the connector 34 is re-fixed, so that the strip slide rail 33 is engaged inside the strip slider 32. The bolts 28 are removed from the side plate 27, and the damaged curved slider 26 and curved slide rail 25 are replaced.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
