Description
Technical Field
[0001] This utility model relates to the field of floating photovoltaic technology, specifically to a floating photovoltaic support structure. Background Technology
[0002] Floating photovoltaic (PV) power generation systems, as a new type of clean energy utilization, have seen rapid development in recent years. Traditional floating PV systems mostly use columns as support points, where the PV panels are connected to the columns, and then the columns are connected to a floating body on the water. While this method is simple and easy to implement, it has many shortcomings in practical applications. For example, the PV modules themselves, as load-bearing components, are easily subjected to excessive deformation and damage under extreme weather conditions. Utility Model Content
[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a floating photovoltaic support that can prevent photovoltaic modules from undergoing large deformation under extreme loads and ensure that the photovoltaic modules are not easily damaged.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A floating photovoltaic (PV) support structure includes at least two tracks and at least two support frames, with at least one support frame on each track. The tracks are used to connect a floating body and are arranged parallel to each other. Each support frame is formed by bending a profile and includes a first connecting part, a first supporting part, a mounting part, a second supporting part, and a second connecting part connected in sequence. The first connecting part and the second connecting part are connected to the tracks, and the extension direction of the first connecting part is opposite to the extension direction of the second connecting part. The first supporting part, the mounting part, and the second supporting part are connected to form an arched structure. The mounting part is provided with at least two locking bolts for locking with the lower edge of the PV module frame and at least two clamping components for abutting against the upper edge of the PV module frame. The locking bolts and clamping components are one-to-one and close to each other, and the locking bolts are spaced apart along the length of the mounting part.
[0005] With the above setup, by making the support frame a one-piece bent component, the photovoltaic module, which was originally a load-bearing component, becomes a plate supported by a beam, compared to the traditional column support legs. This improves the overall rigidity of the installed photovoltaic module, increases the load-bearing area, evenly distributes the load, and enhances wind resistance. Furthermore, factory processing of the support frame makes it easier to control errors and ensures uniform bending angles. Since the lower frame of the photovoltaic module is flush with the top surface of the mounting section, the accuracy of the actual working angle of the photovoltaic panel can be guaranteed. In addition, the locking bolts and clamping components work together to ensure reliable fixation of the photovoltaic module.
[0006] The mounting section is tilted relative to the track, and the tilt angle of the mounting section is the working tilt angle of the photovoltaic module. This arrangement effectively ensures the tilt angle of the photovoltaic module during actual operation.
[0007] The first support portion and the second support portion are set at an angle, and the angle is acute. The acute angle between the first support portion and the second support portion can help to reduce the length of the support frame and increase the installed capacity.
[0008] Each of the aforementioned support frames is also provided with at least one intermediate support, one end of which is connected to the mounting part, and the other end of which is connected to the track. When the support frame is long (for example, when a set of support frames simultaneously fixes two or more sets of photovoltaic modules), the structural strength of the support frame can be improved by setting intermediate supports to reduce the span of the support frame.
[0009] The intermediate support is formed by bending a profile and includes a third connecting part, a third supporting part, and a fourth connecting part connected in sequence. The extension directions of the third connecting part and the fourth connecting part are opposite. The third connecting part connects to the mounting part, the fourth connecting part connects to the track, and the third supporting part is perpendicular to the mounting part. This configuration of the intermediate support results in uniform stress distribution, easy error control, high strength, and resistance to deformation.
[0010] It also includes several locking components. The first connecting part, the second connecting part, and the intermediate support are all connected to the track using locking components. The track has a connecting groove, and the edges of both sides of the connecting groove are bent inward to form a first anti-rotation part. The locking component includes a locking block and a locking screw. The thickness and / or width of the locking block is not greater than the distance between the two first anti-rotation parts, and the length of the locking block is greater than the distance between the two first anti-rotation parts and less than the width of the connecting groove. Both ends of the locking block in the length direction are provided with anti-rotation grooves that cooperate with the first anti-rotation parts to prevent rotation. The locking block is placed in the connecting groove, and the locking screw is threadedly connected to the locking block. With this configuration, the locking block can be inserted into the connecting groove from the gap between the two first anti-rotation parts. When the locking screw is turned, with the tightening action, the first anti-rotation part can cooperate with the second anti-rotation part to prevent rotation, thereby ensuring that the locking screw can be screwed into the locking block for locking, making the connection convenient and quick.
[0011] The clamping assembly includes a clamping member and a clamping bolt. The clamping member comprises a first raised portion, a fifth connecting portion, a second raised portion, and a clamping portion connected in sequence. The first raised portion abuts against the mounting portion. The fifth connecting portion is connected to the mounting portion via the clamping bolt. The second raised portion abuts against the side edge of the photovoltaic module frame, and the clamping portion abuts against the top edge of the photovoltaic module frame. The first raised portion creates a gap between the fifth connecting portion and the mounting portion. As the clamping bolt is tightened, the fifth connecting portion can deform slightly. Under its deformation force, it effectively prevents the clamping bolt from loosening and also accommodates photovoltaic module dimensional errors to a certain extent.
[0012] The pressing part has an anti-slip part on the surface that abuts against the upper edge of the photovoltaic module frame. This design ensures that the upper edge of the photovoltaic module frame is reliably pressed.
[0013] The fifth connecting part is provided with a through hole for the clamping bolt to pass through. The through hole is either a round hole or an oblong hole. In addition, the fifth connecting part is also provided with a positioning groove for positioning the center of the through hole, which is convenient for manual identification. The positioning groove and the through hole are arranged to intersect each other. The through hole is designed as an oblong hole to accommodate the machining errors of the components.
[0014] After adopting the above solution, the integrated support frame design greatly improves the overall rigidity of the photovoltaic module and the load distribution is more uniform, thus possessing excellent tensile, compressive and wind resistance capabilities, significantly improving the safety and reliability of the photovoltaic module, and is particularly suitable for use in floating photovoltaic systems.

Detailed Implementation
[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.
[0019] Example 1 like Figure 1-11 As shown, this embodiment discloses a floating photovoltaic support system, which includes at least two tracks 10 and at least two support frames 20, with at least one support frame 20 on each track 10. The tracks 10 are used to connect floating bodies, and the tracks 10 are arranged parallel to each other. In this embodiment, the support frames 20 arranged opposite to each other on the two tracks 10 jointly support a photovoltaic module 50, and multiple photovoltaic modules 50 can share the tracks 10.
[0020] The support frame 20 is formed by bending a profile, with rounded transitions at the bends. Specifically, the support frame 20 includes a first connecting part 21, a first supporting part 22, a mounting part 23, a second supporting part 24, and a second connecting part 25 connected in sequence. The extension direction of the first connecting part 21 is opposite to the extension direction of the second connecting part 25.
[0021] Both the first connecting part 21 and the second connecting part 25 are connected to the track 10 via a locking assembly. Specifically, the track 10 has a connecting groove 11 extending along its length. The edges of both sides of the connecting groove 11 are bent inward to form a first anti-rotation part 12 (similar to a barb). The locking assembly includes a locking block 31 and a locking screw 32. The thickness H1 and / or width W1 of the locking block 31 is not greater than the distance L2 between the two first anti-rotation parts 12, and the length L1 of the locking block 31 is greater than the distance L2 between the two first anti-rotation parts 12 and less than the groove width W2 of the connecting groove 11. When the locking block 31 approaches the bottom of the connecting groove 11, the locking block 31 should be able to rotate. Anti-rotation grooves that cooperate with the first anti-rotation parts 12 are provided at both ends of the locking block 31 along its length. The locking block 31 is placed in the connecting groove 11 through the gap between the two first anti-rotation parts 12. The locking screw 32 passes through the first connecting part 21 or the second connecting part 25 and is threadedly connected to the locking block 31. By rotating the locking screw 32, the locking block 31 is rotated 90° and then lifted and the locking screw 32 is rotated. The first anti-rotation part 12 can cooperate with the second anti-rotation part 33 to prevent rotation, thereby ensuring that the locking screw 32 can be screwed into the locking block 31 for locking. The connection is convenient and quick.
[0022] The first support portion 22, the mounting portion 23, and the second support portion 24 are connected to form an arched structure. The mounting portion 23 is inclined relative to the track 10, and the inclination angle of the mounting portion 23 is the working inclination angle of the photovoltaic module 50, so as to facilitate the photovoltaic module 50 fixed on the mounting portion 23 to work at the specified inclination angle. In addition, the first support portion 22 and the second support portion 24 are set at an angle A, and this angle A is an acute angle, preferably the latter, so as to shorten the length of the support frame and increase the installed capacity.
[0023] The mounting section 23 is provided with at least two locking bolts 26 for locking with the lower edge of the frame of the photovoltaic module 50, and at least two clamping components for abutting against the upper edge of the frame of the photovoltaic module 50 (generally made of C-shaped profile). The locking bolts 26 and the clamping components are one-to-one and close to each other, and the locking bolts 26 are spaced apart along the length of the mounting section 23. In this case, taking the example of two support frames 20 supporting only one photovoltaic module 50, each support frame 20 is provided with two locking bolts 26 and two clamping components.
[0024] The clamping assembly includes a clamping member 27 and a clamping bolt 28. The clamping member 27 includes a first raised portion 271, a fifth connecting portion 272, a second raised portion 273, and a clamping portion 274, which are integrally formed and connected in sequence. The first raised portion 271 abuts against the mounting portion 23, and the fifth connecting portion 272 is connected to the mounting portion 23 by the clamping bolt 28. The fifth connecting portion 272 is provided with a through hole 275 for the clamping bolt 28 to pass through. The through hole 275 is a round hole or an oblong hole, preferably the latter. The second raised portion 273 abuts against the side edge of the photovoltaic module 50 frame, and the clamping portion 274 abuts against the upper edge of the photovoltaic module 50 frame. The surface of the clamping portion 274 abutting against the upper edge of the photovoltaic module 50 frame is provided with an anti-slip portion 276.
[0025] The fifth connecting part 272 is raised by the first shim 271, and there is a gap between it and the mounting part 23. As the clamping bolt 28 is tightened, it can effectively prevent the clamping bolt 28 from loosening. In addition, it can also accommodate the dimensional errors of the photovoltaic module 50 to a certain extent. For easy manual identification, a positioning groove 277 is also provided on the fifth connecting part 272 at the center of the positioning through hole 275. The positioning groove 277 and the through hole 275 are arranged to intersect each other.
[0026] Example 2 like Figure 12-14 As shown, the difference between this embodiment and Embodiment 1 is that each pair of support frames 20 supports and fixes two photovoltaic modules 50. This results in a larger span for the support frames 20. Therefore, each support frame 20 is also equipped with at least one intermediate support 40. One end of the intermediate support 40 is connected to the mounting part 23, and the other end is connected to the track 10. More specifically, the intermediate support 40 is obtained by bending a profile. The intermediate support 40 includes a third connecting part 41, a third supporting part 42, and a fourth connecting part 43 connected in sequence. The extending direction of the third connecting part 41 is opposite to the extending direction of the fourth connecting part 43.
[0027] The third connecting part 41 is bolted to the mounting part 23, and the fourth connecting part 43 is connected to the track 10 via a locking assembly as described in Embodiment 1. The third support part 42 is set perpendicular to the mounting part 23. This configuration of the intermediate support 40 results in uniform stress distribution, easy error control, high strength, and resistance to deformation. When the support frame 20 is long, the structural strength of the support frame 20 can be guaranteed by setting the intermediate support 40.
[0028] In this embodiment, two photovoltaic modules 50 on the same support frame 20 share a clamping component on adjacent sides. When sharing the component, the structure of the clamping component can be adjusted appropriately for adaptation.
[0029] In summary, this utility model, by setting the support frame 20 as an integrally formed bent component, transforms the photovoltaic module 50 from a load-bearing component itself into a plate supported by a beam, compared to traditional column support legs. This improves the overall rigidity of the photovoltaic module 50 after installation, increases the load-bearing area, evenly distributes the load, and enhances wind resistance. Furthermore, factory processing of the support frame 20 makes it easier to control errors and ensures uniform bending angles. Since the lower frame of the photovoltaic module 50 is tightly attached to the top surface of the mounting section 23, the accuracy of the actual working angle of the photovoltaic panel can be ensured. In addition, the locking bolts 26 and the clamping components work together to ensure reliable fixation of the photovoltaic module 50. Moreover, if the support frame 20 is long, an intermediate support 40 can be added to support the middle section of the mounting section 23 to ensure structural strength.
[0030] The above description is merely an embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
