Description

Technical Field

[0001] This utility model relates to the technical field of solar photovoltaics, and in particular to a photovoltaic support structure and a floating photovoltaic 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 often use a horizontal arrangement of PV panels. While simple and easy to implement, this method has many shortcomings in practical applications. For example, a wind-resistant floating PV platform disclosed in Chinese Patent Publication No. CN 221893251 U features horizontally distributed PV panels, each requiring at least four supports. These supports are typically located on the front and rear sides of the PV panel, resulting in a large number of components and complex installation. Furthermore, due to the scarcity and dispersed nature of land and water resources for PV systems, the horizontal arrangement also limits further increases in installation density.

[0003] As a result, vertically arranged photovoltaic panel systems have emerged on the market. For example, the floating multi-functional integrated water surface photovoltaic support system suitable for high-altitude and cold regions disclosed in Chinese Patent Announcement No. CN 210041705U can reduce the gap between photovoltaic panels by arranging them vertically, which helps to increase the installation density. However, the support columns in this solution are usually set on the long side of the photovoltaic panel. Since the photovoltaic panel is tilted with the front lower than the back when in use, it will slide downwards when directly placed on the column during assembly. Therefore, at least one person is needed to help lift the photovoltaic panel and accurately position it on the column, and then another person can press the four pressure blocks to fix it to each column. The assembly process is quite laborious, and one person supports the photovoltaic panel while another person installs it, resulting in low on-site installation efficiency. Although the solution has mounting shims, and the mounting shims are limited by the front and rear of the column mounting shim limiting baffle, the mounting shims and photovoltaic panels only have left and right limits and up and down limits achieved by the pressure blocks. Neither the column nor the mounting shims can limit the front and rear sliding of the photovoltaic panel. Meanwhile, the plan proposes that, in order to prevent the photovoltaic panels from sliding, after the photovoltaic panels and columns are assembled, additional component limiting devices located at the bottom of the photovoltaic panels need to be installed on the longitudinal beams to limit the downward sliding of the photovoltaic panels. However, since the component limiting device is an independent installation step, if this step is omitted during the actual installation process, it is easy to cause the photovoltaic panels to shift downwards and become misaligned or even further damaged during later use. Utility Model Content

[0004] The purpose of this invention is to provide a floating photovoltaic structure that has the advantages of saving parts, reducing costs, and increasing installation density and efficiency.

[0005] To achieve the above objectives, the solution of this utility model is:

[0006] A photovoltaic support structure includes a connecting leg, a pressure block, a limiting plate, a first connector, and a second connector;

[0007] The bottom of the connecting leg is used to connect with the track, and the top of the connecting leg has a front retaining wall and a locking groove; the pressure block has a snap-fit ​​part and a locking part, and the locking part is provided with a lock hole.

[0008] The limiting plate can overlap the top of the connecting leg and is limited by the front retaining wall;

[0009] The limiting plate is provided with a first connecting hole and a second connecting hole; the first connecting member passes through the first connecting hole and the connecting hole provided on the bottom surface of the photovoltaic panel, and is used to lock and fix the limiting plate to the photovoltaic panel; the second connecting member passes through the locking groove, the second connecting hole and the locking hole, and is used to interlock the locking part of the connecting leg, the limiting plate and the pressure block into one piece, while the snap-fit ​​part of the pressure block is used to press and fix the long edge of the photovoltaic panel to the limiting plate.

[0010] Furthermore, the front side of the top surface of the connecting leg has a boss, and the rear side wall of the boss is the front retaining wall; the rear side of the top surface of the connecting leg has an inclined overlapping plane, which is used for the positioning plate to overlap and be placed.

[0011] Furthermore, the locking groove is located below the overlapping plane, and is a rectangular groove extending left and right, with a slot that penetrates the overlapping plane. Two relatively extending snap-fit ​​edges are formed at the slot. The second connector includes a screw and a nut with anti-rotation planes on both sides of the head. The shank of the second connector screw extends out of the slot and passes through the second connecting hole and the locking hole. The snap-fit ​​edges are used to snap and limit the head of the second connector screw, while the front and rear sidewalls of the rectangular groove are used to limit the anti-rotation planes of the head of the second connector screw.

[0012] Furthermore, the limiting plate has an overlapping portion that overlaps the overlapping plane and a connecting portion that extends out of the overlapping plane; the overlapping portion is provided with a second connecting hole that extends horizontally, and the connecting portion is provided with a first connecting hole that extends front-back.

[0013] This utility model also provides a floating photovoltaic structure, including a float, tracks, supports, and photovoltaic panels; the tracks are multiple tracks extending forward and backward and distributed laterally on the float; the photovoltaic panels are multiple, each vertically arranged and arranged laterally on each track; each photovoltaic panel is inclined, with the rear short side of the photovoltaic panel higher than the front short side, and the two long sides of the left and right sides of the photovoltaic panel are connected to the tracks through at least two supports of different heights arranged forward and backward.

[0014] At least one leg on the long side of the photovoltaic panel adopts the photovoltaic leg structure described above.

[0015] Furthermore, the photovoltaic panel has two legs connected to its long side, namely a front leg and a rear leg distributed at the front and back. The height of the front leg is lower than that of the rear leg, and both the front leg and the rear leg adopt the photovoltaic leg structure.

[0016] Furthermore, the top surface of the track is provided with a sliding groove, and the bottom of the support leg is provided with a locking block assembly on the front and rear sides, which can be slidably locked into the sliding groove.

[0017] Furthermore, the floating body includes a front floating body assembly and a rear floating body assembly, which are distributed at intervals. The front and rear ends of each track are respectively attached to the front floating body assembly and the rear floating body assembly, connecting the front floating body assembly and the rear floating body assembly into one unit. Each photovoltaic panel is installed between the front floating body assembly and the rear floating body assembly.

[0018] Both the front float assembly and the rear float assembly include several sub-floats connected sequentially from left to right; the top surface of each sub-float has three slots (left, center, and right), and each slot contains a track; a photovoltaic panel or two or more photovoltaic panels spaced apart front to back are installed between each pair of the three tracks on each sub-float, and the left and right photovoltaic panels are adjacent and share the track on the middle slot and the limiting plate on the top of the support foot on the track.

[0019] Furthermore, the pressure blocks provided on the support feet of the rails in the left and right slots of the sub-float are side pressure blocks, each with a locking part, while the pressure blocks provided on the support feet of the rails in the middle slot are center pressure blocks, each with locking parts on both the left and right sides; the float also includes a left float assembly and a right float assembly, which have the same structure and are spaced apart from each other, with their front and rear ends connected to the left and right ends of the front float assembly and the rear float assembly, respectively.

[0020] Furthermore, the depth of the middle slot of the sub-buoy is greater than the depth of the left and right slots, and the height of the track in the middle slot is higher than the height of the tracks in the left and right slots, so that the upper surface of the middle track and the upper surface of the left and right tracks are kept at the same level.

[0021] After adopting the above technical solution, the photovoltaic panels can be assembled conveniently, labor-savingly, and quickly. The assembly of this floating photovoltaic structure can be carried out using the following steps: First, tracks can be set on the floating body, and then front and rear spaced supports can be installed at predetermined positions on two adjacent tracks; second, each limiting plate is locked and fixed to the bottom surface of the long side of the photovoltaic panel using the first connector. Then, two people can work simultaneously to lift the photovoltaic panel and place it over each support, ensuring that the limiting plates on both long sides overlap the top of the corresponding connecting supports and are limited by the corresponding front retaining wall. At this point, the worker can release the photovoltaic panel, which can then be released by the limiting plates on the two long sides. The positioning plate enables positioning and limiting of the photovoltaic panel with each support leg, eliminating the need for workers to apply force for positioning the photovoltaic panel for extended periods, thus saving labor. Finally, two workers can work simultaneously from both sides, using the second connector to lock each pressure block, the positioning plate, and the connecting support leg into one unit. The pressure block's locking part presses and holds the long edge of the photovoltaic panel, achieving a stable connection between the two long edges of the photovoltaic panel and each support leg. Two workers working simultaneously can significantly improve construction efficiency. Since the positioning plate is also locked and fixed to the bottom surface of the photovoltaic panel, it achieves coordinated fixing from top to bottom. After the final construction is completed, the connection strength between the photovoltaic panel and the support leg is high, ensuring the photovoltaic panel's wind resistance and earthquake resistance.

[0022] The above structure allows for convenient and rapid assembly and installation of the floating photovoltaic structure. Compared with existing technologies, it eliminates the assembly steps of the component limiting parts at the bottom of the photovoltaic panel. The innovative setting of the limiting plate ensures the limiting and positioning between the photovoltaic panel and each support leg during assembly, saving manpower and significantly improving the assembly efficiency of the photovoltaic system. It also prevents the photovoltaic panel from slipping forward during installation or later use, thus improving the reliability of the photovoltaic system. Attached Figure Description

Detailed Implementation

[0036] 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. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0037] Example 1

[0038] like Figures 1 to 8 As shown, a floating photovoltaic structure in this embodiment includes a float 1, a track 2, legs 3, and a photovoltaic panel 4.

[0039] The tracks 2 are multiple, extending forward and backward, and distributed laterally on the float 1 at intervals; the photovoltaic panels 4 are multiple, each vertically arranged and distributed on each track 2; each photovoltaic panel 4 is inclined, with the rear short side 41 of the photovoltaic panel 4 higher than the front short side 42, and the two long sides 43 on the left and right sides of the photovoltaic panel 4 are connected to the tracks 2 through the support legs 3 respectively.

[0040] like Figure 2 As shown, at least one support 3 on the long side 43 of the photovoltaic panel 4 can adopt the photovoltaic support structure 30 described below.

[0041] The photovoltaic support structure 30 includes a connecting support 31, a pressure block 32, a limiting plate 33, a first connecting member 34, and a second connecting member 35.

[0042] See Figure 4 and Figure 6 The bottom of the connecting leg 31 is used to connect with the track 2, and the top of the connecting leg 31 has a front retaining wall 311 and a locking groove 312; the bottom surface of the long side 43 of the photovoltaic panel 4 is provided with a connecting hole 431; the pressure block 32 has a snap-fit ​​part 321 and a locking part 322, the snap-fit ​​part 321 is used to snap onto the upper surface of the edge of the photovoltaic panel 4, and the locking part 322 is provided with a lock hole 323.

[0043] The limiting plate 33 is provided with a first connecting hole 331 and a second connecting hole 332. The first connecting member 34 passes through the first connecting hole 331 and the connecting hole 331, and locks the limiting plate 33 to the photovoltaic panel 4. The limiting plate 33 overlaps the top of the connecting leg 31 and is limited by the front retaining wall 311, which can restrict and prevent the photovoltaic panel 4 connected to the limiting plate 33 from sliding downward. The second connecting member 35 passes through the locking groove 312, the second connecting hole 332 and the locking hole 323, and connects the connecting leg 31, the limiting plate 33 and the locking part 322 of the pressure block 32 into a whole. The photovoltaic panel 4, the pressure block 32 and the second connecting member 35 can move left and right along the locking groove 312 for fine adjustment. The snap-fit ​​part 321 of the pressure block 32 presses and fixes the edge of the photovoltaic panel 4 to the limiting plate 33. The limiting plate 33 is also locked and fixed to the bottom surface of the photovoltaic panel 4, thereby achieving upper and lower coordinated fixation, high connection strength, and strengthening the fixing effect of the photovoltaic panel 4.

[0044] The photovoltaic panel 4 has at least two legs 3 connected to its long side 43, which can be divided into front legs 36 and rear legs 37 distributed front and rear. The height of the front legs 36 is lower than that of the rear legs 37 in order to maintain the tilt of the photovoltaic panel 4. In this embodiment, the photovoltaic leg structure 30 is used on both the front legs 36 and the rear legs 37. Of course, the photovoltaic leg structure 30 can also be used only on the front legs 36 or the rear legs 37, and the other front legs 36 or rear legs 37 can be directly connected and fixed to the photovoltaic panel 4 by the existing pressure block 32.

[0045] Therefore, by setting up this photovoltaic support structure 30, the photovoltaic panel 4 can be assembled conveniently, effortlessly, and quickly. The assembly of this floating photovoltaic structure can be carried out using the following steps:

[0046] First, a track 2 can be set on the float 1, and then front support legs 36 and rear support legs 37 with a front-to-back interval can be installed at predetermined positions on two adjacent tracks 2 respectively.

[0047] Secondly, each limiting plate 33 is locked and fixed to the bottom surface of the long side 43 of the photovoltaic panel 4 using the first connector 34. Then, two people can work at the same time to lift the photovoltaic panel 4 and place it on top of each support leg 3. The limiting plates 33 on the two long sides 43 are placed on the top of the corresponding connecting support leg 31 and are ensured to be limited by the corresponding front retaining wall 311. At this time, the worker can release the photovoltaic panel 4. The photovoltaic panel 4 can achieve positioning and limitation with each connecting support leg 31 by means of the limiting plates 33 on the two long sides 43.

[0048] Finally, two workers can work simultaneously, using the second connector 35 to lock each pressure block 32 to the limiting plate 33 and the connecting leg 31 as one unit, and using the clamping part 321 of the pressure block 32 to press and clamp the edge of the long side 43 of the photovoltaic panel 4, so as to achieve a stable connection between the two long sides 43 of the photovoltaic panel 4 and each connecting leg 31, ensuring the wind resistance and shock resistance of the photovoltaic panel 4. The simultaneous construction by two people can greatly improve the construction efficiency.

[0049] The above structure allows for convenient and rapid assembly and installation of the waterborne photovoltaic structure, saving manpower and significantly improving the assembly efficiency of the photovoltaic system. Furthermore, the assembly process effectively ensures the limiting and fixing between the photovoltaic panel 4 and each connecting leg 31, preventing the photovoltaic panel 4 from slipping forward.

[0050] like Figure 4 Both the first connector 34 and the second connector 35 can adopt a screw and nut mating structure, but are not limited thereto; in this embodiment, the first connector 34 takes an external hexagonal screw and an external hexagonal nut as an example, and the second connector 35 takes a screw and an external hexagonal nut with anti-rotation planes 351 on both sides of the head as an example.

[0051] Specifically, the front side of the top surface of the connecting leg 31 may have a boss 313, and the rear side wall of the boss 313 is the front retaining wall 311; the rear side of the top surface of the connecting leg 31 has an inclined overlapping plane 314, which is used for the positioning plate 33 to overlap and be placed; the locking groove 312 may be provided below the overlapping plane 314, and may be rectangular groove, and has a slot 315 that penetrates the overlapping plane 314. Two relatively extending snap-fit ​​edges 316 are formed at the slot 315. The rod portion 352 of the second connecting member 35 screw can extend out of the slot 315, and the snap-fit ​​edges 316 are used to snap and limit the head 353 of the second connecting member 35 screw, while the front and rear side walls 317 of the rectangular groove are used to limit the anti-rotation plane 351 of the head 353 of the second connecting member 35 screw.

[0052] The limiting plate 33 has an overlapping portion 333 that overlaps the overlapping plane 314, and a connecting portion 334 that extends out of the overlapping plane 314. The overlapping portion 333 is provided with a strip-shaped second connecting hole 332 that extends left and right, and the connecting portion 334 is provided with a strip-shaped first connecting hole 331 that extends front and back, so as to facilitate fine adjustment of the first connecting member 34 and the second connecting member 35 during assembly and improve assembly efficiency.

[0053] like Figures 1 to 3 As shown in this embodiment, the top surface of the track 2 is provided with a sliding groove 21, and the bottom front and rear sides of the connecting support leg 31 are respectively provided with locking block components 38, which can be slidably locked into the sliding groove 21, so that the installation position of the support leg 3 and the track 2 can be easily adjusted. The specific structure of the locking block component 38 and the sliding groove 21 can refer to the prior art.

[0054] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the float 1 in this embodiment includes a front float assembly 11 and a rear float assembly 12, which are distributed at intervals. The front float assembly 11 and the rear float assembly 12 are respectively connected to the front float assembly 11 and the rear float assembly 12 at their front and rear ends, and the front float assembly 11 and the rear float assembly 12 are connected as one unit, which can ensure sufficient buoyancy and good support effect. Each photovoltaic panel 4 is installed between the front float assembly 11 and the rear float assembly 12, and the top surface of the front float assembly 11 and the rear float assembly 12 can form a maintenance passage for people to walk on, which facilitates the later maintenance of the photovoltaic panel 4.

[0055] Specifically, the front float assembly 11 and the rear float assembly 12 can have corresponding structures and both adopt the same construction.

[0056] In this embodiment, both the front float assembly 11 and the rear float assembly 12 include six sub-floats 111. Each sub-float 111 is divided into two adjacent groups, and each group includes three horizontally distributed sub-floats 111 connected to each other in sequence. The left and right sub-floats 111 can be connected by plastic connectors 5, and the front and rear groups of sub-floats 111 can be connected by rails 2. Of course, the number of sub-floats 111 and the number of groups of the front float assembly 11 and the rear float assembly 12 are not limited to this.

[0057] The top surface of the sub-float 111 may have three slots 112 on the left, center and right. Each slot 112 contains a track 2, which can prevent the track 2 from protruding from the surface of the front float 1 and affecting movement. In this embodiment, there are a total of nine tracks 2 between the front float assembly 11 and the rear float assembly 12.

[0058] In this embodiment, the photovoltaic panels 4 are arranged vertically from left to right. That is, the width of the photovoltaic panel 4 is the length of the shorter side. Since the length itself is relatively short, a photovoltaic panel 4 can be installed between each pair of the three tracks 2 on each sub-float 111. In other words, the two photovoltaic panels 4 on the left and right can be adjacent and share the track 2 on the middle slot 112.

[0059] Therefore, the gap between every two photovoltaic panels 4 can be reduced. Compared to the existing horizontally arranged photovoltaic panels 4, which have large gaps, the vertically arranged photovoltaic panels 4 in this embodiment eliminate one gap between every two photovoltaic panels 4. Thus, after the photovoltaic panels 4 are installed in batches, the actual footprint of all photovoltaic panels 4 can be reduced, thereby increasing the installed density of the photovoltaic structure. Moreover, using a sub-float 111 to support two photovoltaic panels 4 can minimize the electrical wiring and control costs.

[0060] In this embodiment, a total of six photovoltaic panels 4 can be installed on the nine tracks 2.

[0061] In this embodiment, the pressure blocks 32 provided on the support feet 3 of the track 2 in the left and right slots 112 of the sub-float 111 are side pressure blocks 324, and the side pressure blocks 324 have only one locking part 321. The pressure blocks 32 provided on the support feet 3 of the track 2 in the middle slot 112 are middle pressure blocks 325, and the middle pressure blocks 325 have locking parts 321 on both the left and right sides, so as to press and fix the adjacent long sides 43 edges of the two photovoltaic panels 4.

[0062] Moreover, during assembly, two adjacent photovoltaic panels 4 can be assembled simultaneously, and the adjacent long sides 43 of the two adjacent photovoltaic panels 4 can share a limiting plate 33. The limiting plate 33 is provided with two first connecting holes 331 spaced apart from each other.

[0063] See also Figure 9 and Figure 10In this embodiment, the depth of the central slot 112 of the sub-float 111 can be greater than the depth of the left and right slots 112, and the height A1 of the track 2 inside the central slot 112 is higher than the height A2 of the track 2 inside the left and right slots 112, so that the upper surface of the central track 2 and the upper surface of the left and right tracks 2 are kept at the same level. This not only improves the support force on the shared track 2 between the two photovoltaic panels 4, but also ensures that the track 2 in the middle of the sub-float 111 bears more weight, so that the stress point of the sub-float 111 is closer to the center point, making the floating system composed of the entire float 1 more stable.

[0064] In this embodiment, the float 1 may further include a left float assembly 13 and a right float assembly 14. The left float assembly 13 and the right float assembly 14 have the same structure and are spaced apart from each other. Their front and rear ends are respectively connected to the left and right ends of the front float assembly 11 and the rear float assembly 12, so that the front float assembly 11, the rear float assembly 12, the left float assembly 13 and the right float assembly 14 constitute a stable floating system. The top surfaces of the left float assembly 13 and the right float assembly 14 can also form a maintenance channel.

[0065] In this embodiment, both the left float assembly 13 and the right float assembly 14 include eight side floats 113. The side floats 113 are arranged adjacent to each other front and back, and their tops can be connected and fixed by two left-right spaced connecting rails 114. The connecting rails 114 can be accommodated in the connecting grooves 115 recessed on the top surface of the side floats 113. The floats 1 are easy and quick to assemble.

[0066] Example 2

[0067] like Figure 11 and Figure 12 As shown, the structure of this embodiment is basically the same as that of the above embodiment. The main difference is that the photovoltaic panel 4 in this embodiment has two rows distributed in the front and back, with six photovoltaic panels 4 in each row, for a total of twelve photovoltaic panels 4.

[0068] In this embodiment, both the left float assembly 13 and the right float assembly 14 include thirteen side floats 113. Two rows of photovoltaic panels 4 are arranged at intervals on the nine tracks 2 between the front float assembly 11 and the rear float assembly 12. That is, two photovoltaic panels 4 can be installed at intervals between each pair of tracks 2 on the three tracks 2 of each float 1.

[0069] This indicates that the number of photovoltaic panels 4 is not limited to six or twelve, nor is it limited to a single row distributed from left to right. It can also be distributed in multiple rows from front to back. The specific arrangement can be adjusted according to actual needs and the size of the photovoltaic panels 4.
