Description

Technical Field

[0001] The present invention relates to the technical field of solar photovoltaics, in particular to a photovoltaic support leg structure, an above-water photovoltaic structure and a construction method. Background Art

[0002] As a new type of clean energy utilization method, water-based photovoltaic power generation systems have developed rapidly in recent years. Traditional water-based photovoltaic systems mostly use a horizontal arrangement to install photovoltaic panels. Although this method is simple and easy to use, it has many shortcomings in actual application. For example, China Patent Authorization Announcement No. CN 221893251 U discloses a wind-resistant water-based photovoltaic platform. In this scheme, each photovoltaic panel is distributed horizontally, and each photovoltaic panel requires at least four legs for support. Each leg is generally set on the front and back sides of the photovoltaic panel. There are many parts and components, and the installation is relatively complicated. At the same time, due to the shortage of photovoltaic land and water resources and the scattered layout, the horizontal arrangement method also limits the further improvement of the installed density.

[0003] As a result, vertical photovoltaic panel systems have emerged on the market, such as the floating multifunctional integrated water-based photovoltaic support system suitable for alpine regions disclosed in Chinese Patent Authorization Publication No. CN 210041705U. This solution, by arranging the photovoltaic panels vertically, can reduce the gaps between them, helping to increase installation density. However, the support columns in this solution are typically located on the left and right long sides of the photovoltaic panels. Since the photovoltaic panels are tilted in use, with the front lower and the back higher, they will slide downward when placed directly on the columns during assembly. Therefore, at least one person is required to assist in lifting the photovoltaic panel and accurately positioning it on the columns. Another person then needs to tighten the four pressure blocks of the hole lock assembly to secure it to the columns. This assembly process is relatively laborious, and one person supports the photovoltaic panel while the other performs the installation, resulting in low on-site installation efficiency. Although this solution includes mounting gaskets, which are limited forward and backward by the column mounting gasket limit baffles, the mounting gaskets and the photovoltaic panels are only limited left and right and up and down by the pressure blocks. Neither the column nor the mounting gasket can prevent the photovoltaic panel from sliding forward and backward. At the same time, the plan proposes that in order to prevent the photovoltaic panels from sliding, after the photovoltaic panels and the columns are assembled, additional component limiters need to be set on the longitudinal beams at the bottom of the photovoltaic panels to limit the position and prevent the photovoltaic panels from sliding downward; however, because the component limiters are an independent installation step, if this step is omitted during the actual installation process, it is easy to cause the photovoltaic panels to move downward and misplaced during later use, or even further damage. Summary of the Invention

[0004] The purpose of the present invention is to provide a photovoltaic support leg structure, an above-water photovoltaic structure and a construction method, which have the advantages of saving parts and reducing costs, and improving installation density and installation efficiency.

[0009] The present invention also provides an aquatic photovoltaic structure, comprising a float, tracks, legs, and photovoltaic panels; the tracks are multiple, extending front and rear, and are distributed on the float at intervals on the left and right sides; the photovoltaic panels are multiple, vertically arranged and distributed on the tracks; each photovoltaic panel is arranged obliquely, with the rear short side of the photovoltaic panel higher than the front short side, and the two long sides of the photovoltaic panel on the left and right sides are connected to the track by at least two legs arranged front and rear at different heights; At least one support leg on the long side of the photovoltaic panel adopts the photovoltaic support leg structure.

[0010] Furthermore, there are two legs connected to the long side of the photovoltaic panel, which are divided into a front leg and a rear leg distributed front and back. The height of the front leg is lower than that of the rear leg, and the photovoltaic leg structure is adopted on both the front leg and the rear leg.

[0011] Furthermore, a slide groove is provided on the top surface of the track, and a clamping block assembly is provided on the front and rear sides of the bottom of the support leg so as to be slidably engaged in the slide groove.

[0012] Furthermore, the floating body includes a front floating body assembly and a rear floating body assembly, the front floating body assembly and the rear floating body assembly are spaced apart from each other, and the front and rear ends of each track are respectively overlapped on the front floating body assembly and the rear floating body assembly, thereby connecting the front floating body assembly and the rear floating body assembly into one body, and each photovoltaic panel is installed between the front floating body assembly and the rear floating body assembly; Both the front float assembly and the rear float assembly include several sub-floats connected in sequence on the left and right sides; the top surfaces of the sub-floats have three slots on the left, middle and right sides, and each slot contains a track; a photovoltaic panel or two or more photovoltaic panels spaced front and back are installed between two 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 limit plate on the top of the support leg on the track.

[0013] Furthermore, the pressure blocks arranged on the legs on the rails in the left and right slots on the sub-float are side pressure blocks, which have a clamping portion, while the pressure blocks arranged on the legs on the rails in the middle slot are middle pressure blocks, which have clamping portions 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 left and right, and their front and rear ends are respectively connected to the left and right ends of the front float assembly and the rear float assembly.

[0014] Furthermore, the depth of the middle slot of the sub-float 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 surfaces of the left and right tracks remain at the same level.

[0015] After adopting the above technical solution, the assembly of photovoltaic panels can be realized conveniently, labor-savingly and quickly. The following steps can be adopted during the construction and assembly of the water photovoltaic structure: first, the track can be set on the floating body, and then the front and rear spaced support legs are installed at the predetermined positions of the two adjacent tracks; secondly, each limit plate is locked and fixed to the bottom surface of the long side of the photovoltaic panel using the first connecting piece, and then two people can work at the same time to lift the photovoltaic panel and overlap it on top of each support leg, and make the limit plates on the two long sides overlap the top of the corresponding connecting support legs and ensure that they are limited by the corresponding front retaining wall. At this time, the workers can loosen the photovoltaic panel, and the photovoltaic panel can be connected to each support leg through the limit plates on the two long sides. The positioning and limiting between them is achieved without the need for workers to exert force for a long time to position the photovoltaic panels, which can save energy. Finally, two workers can work on both sides at the same time, use the second connecting piece to lock each pressure block with the limit plate and the connecting leg into one, and use the pressure block clamping part to clamp the long side edge of the photovoltaic panel to achieve a stable connection between the two long sides of the photovoltaic panel and each leg. The simultaneous construction of two people can greatly improve the construction efficiency. Since the limit plate is locked and fixed to the bottom surface of the photovoltaic panel, the upper and lower coordinated fixation is achieved. After the construction is finally completed, the connection strength between the photovoltaic panel and the supporting leg is high, which can ensure the wind resistance and earthquake resistance of the photovoltaic panel. Repeat the above steps until all photovoltaic panels are installed.

[0016] The above-mentioned structure and method can be used to conveniently and quickly realize the assembly and installation of the water photovoltaic structure. Compared with the existing technology, the component limiters and assembly steps at the bottom of the photovoltaic panel are eliminated during the assembly process, saving parts. The innovative setting of the limit plate can ensure the limitation and positioning between the photovoltaic panel and each support leg during assembly, saving manpower and greatly improving the assembly efficiency of the photovoltaic system, avoiding the photovoltaic panel from sliding forward during installation or later use, and improving the reliability of the photovoltaic system.

DETAILED DESCRIPTION

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0020] Example 1 like Figures 1 to 8 As shown, an above-water photovoltaic structure of this embodiment includes a float 1, a track 2, a support leg 3 and a photovoltaic panel 4.

[0021] There are multiple tracks 2 extending forward and backward, and distributed on the floating body 1 at intervals on the left and right sides; there are multiple photovoltaic panels 4, which are vertically arranged and distributed on each track 2 in an arrangement on the left and right sides; each photovoltaic panel 4 is tilted, and the rear short side 41 of the photovoltaic panel 4 is 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 track 2 through the support legs 3 respectively.

[0022] like Figure 2 As shown, at least one leg 3 on the long side 43 of the photovoltaic panel 4 may adopt the photovoltaic leg structure 30 described below.

[0023] The photovoltaic support leg structure 30 includes a connecting leg 31 , a pressing block 32 , a limiting plate 33 , a first connecting member 34 and a second connecting member 35 .

[0024] See Figure 4 and Figure 6 The bottom of the connecting leg 31 is used to connect to the track 2, and the top of the connecting leg 31 has a front baffle 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 pressing block 32 has a clamping portion 321 and a locking portion 322, the clamping portion 321 is used to clamp to the upper surface of the edge of the photovoltaic panel 4, and the locking portion 322 is provided with a lock hole 323.

[0025] When the locking cam 331 is unlocked, the locking cam 332 is unlocked and the locking cam 333 is unlocked, so that the locking cam 332 can be unlocked and the locking cam 333 can be unlocked.

[0026] There are at least two legs 3 connected to the long side 43 of the photovoltaic panel 4, which can be divided into a front leg 36 and a rear leg 37 distributed front and back. The height of the front leg 36 is lower than that of the rear leg 37 to facilitate maintaining the inclination of the photovoltaic panel 4; in this embodiment, the photovoltaic leg structure 30 is adopted on both the front leg 36 and the rear leg 37. Of course, the photovoltaic leg structure 30 can also be adopted only on the front leg 36 or the rear leg 37, and the remaining front legs 36 or the rear legs 37 are directly connected and fixed to the photovoltaic panel 4 using the existing pressing blocks 32.

[0027] Thus, by providing the photovoltaic support structure 30, the photovoltaic panel 4 can be assembled conveniently, labor-savingly and quickly. The following steps can be adopted during the construction and assembly of the water photovoltaic structure: In step S1 , the rails 2 are set on the floating body 1 , and then the front support legs 36 and the rear support legs 37 are installed at predetermined positions of two adjacent rails 2 .

[0028] In step S2, each limit plate 33 is locked and fixed to the bottom surface of the long side 43 of the photovoltaic panel 4 using the first connecting member 34. Then two people can work at the same time to lift the photovoltaic panel 4 and overlap it on top of each support leg 3, and make the limit plates 33 of the two long sides 43 overlap the top of the corresponding connecting leg 31 and ensure that they are limited by the corresponding front baffle wall 311. At this time, the workers can loosen the photovoltaic panel 4, and the photovoltaic panel 4 can be positioned and limited between the connecting legs 31 by the limit plates 33 on the two long sides 43.

[0029] In step S3, two workers can work at the same time, using the second connecting piece 35 to lock each pressing block 32 with the limit plate 33 and the connecting leg 31 as one, and use the clamping part 321 of the pressing block 32 to clamp the edge of the long side 43 of the photovoltaic panel 4, so as to achieve a firm connection between the two long sides 43 of the photovoltaic panel 4 and each connecting leg 31, ensuring the wind resistance and earthquake resistance of the photovoltaic panel 4. Two people working at the same time can greatly improve construction efficiency.

[0030] Step S4, repeating the above steps S1 to S3 until all photovoltaic panels are installed.

[0031] The above-mentioned structure and method can be used to conveniently and quickly realize the assembly and installation of the water photovoltaic structure, which can save manpower and greatly improve the assembly efficiency of the photovoltaic system. In addition, the limited fixation between the photovoltaic panel 4 and each connecting leg 31 is effectively ensured during the assembly process, which can prevent the photovoltaic panel 4 from slipping forward.

[0032] like Figure 4 The first connecting member 34 and the second connecting member 35 can both adopt a screw and nut matching structure, but are not limited to this; the first connecting member 34 of this embodiment takes an external hexagonal screw and an external hexagonal nut as an example, and the second connecting member 35 takes a screw and an external hexagonal nut with anti-rotation flats 351 on both sides of the head as an example.

[0033] Specifically, the front side of the top of the connecting leg 31 may have a boss 313, and the rear side wall of the boss 313 is the front baffle wall 311; the rear side of the top surface of the connecting leg 31 has an inclined overlapping plane 314, and the overlapping plane 314 is for the limiting plate 33 to overlap and place; the locking groove 312 can be arranged below the overlapping plane 314, and can be a rectangular groove shape, and has a notch 315 that passes through the overlapping plane 314, and two relatively extended clamping edges 316 are formed at the notch 315, and the rod 352 of the screw of the second connecting member 35 can extend out of the notch 315, and the clamping edge 316 is used to clamp and limit the head 353 of the screw of the second connecting member 35, and 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 screw of the second connecting member 35.

[0034] The limiting plate 33 has an overlapping portion 333 overlapping the overlapping plane 314, and a connecting portion 334 extending outside the overlapping plane 314. The overlapping portion 333 is provided with a second connecting hole 332 in the form of a strip extending left and right, and the connecting portion 334 is provided with a first connecting hole 331 in the form of a strip extending front and back, so as to facilitate fine-tuning of the first connecting member 34 and the second connecting member 35 during assembly, thereby improving assembly efficiency.

[0035] like Figures 1 to 3 As shown, in this embodiment, a slide groove 21 is provided on the top surface of the track 2, and the front and rear sides of the bottom of the connecting leg 31 can be respectively provided with a block assembly 38 and can be slidably engaged in the slide groove 21 forward and backward, so that the installation position of the leg 3 and the track 2 can be conveniently adjusted. The specific structure of the block assembly 38 and the slide groove 21 can refer to the existing technology.

[0036] like Figure 1 、 Figure 2 、 Figure 7 and Figure 8 As shown, the float 1 of this embodiment includes a front float assembly 11 and a rear float assembly 12, and the front float assembly 11 and the rear float assembly 12 are spaced apart from each other in the front and rear directions, and the front and rear ends of each track 2 are respectively overlapped on the front float assembly 11 and the rear float assembly 12, and the front float assembly 11 and the rear float assembly 12 are connected as a whole, 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, which is convenient for the later maintenance of the photovoltaic panel 4.

[0037] Specifically, the structures of the front float assembly 11 and the rear float assembly 12 may correspond to each other and adopt the same structure.

[0038] In this embodiment, the front float assembly 11 and the rear float assembly 12 each include six sub-floats 111, each sub-float 111 is divided into two adjacent groups front and back, each group includes three sub-floats 111 distributed laterally and connected left and right 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 and number of sub-floats 111 of the front float assembly 11 and the rear float assembly 12 are not limited to this.

[0039] The top surface of the sub-float 111 may have three slots 112 on the left, middle and right, and each slot 112 may contain a track 2 to prevent the track 2 from protruding from the surface of the front float 1 and affecting walking. In this embodiment, there are a total of nine tracks 2 between the front float assembly 11 and the rear float assembly 12.

[0040] The photovoltaic panels 4 of this embodiment are arranged vertically left and right, that is, the left and right widths of the photovoltaic panels 4 are the lengths of the short sides, and the lengths themselves are relatively short. Therefore, a photovoltaic panel 4 can be installed between two of the three tracks 2 on each sub-float 111, that is, the left and right photovoltaic panels 4 can be adjacent to each other and share the track 2 on the middle slot 112.

[0041] This reduces the gap between each pair of photovoltaic panels 4. Compared to conventional horizontally arranged photovoltaic panels 4, which often have large gaps between them, this embodiment eliminates a gap between each pair of vertically arranged photovoltaic panels 4. Consequently, after batch installation of the photovoltaic panels 4, the actual footprint of all photovoltaic panels 4 can be reduced, thereby increasing the installed density of the photovoltaic structure. Furthermore, using a single sub-floating body 111 to support two photovoltaic panels 4 minimizes electrical wiring, thus controlling costs.

[0042] In this embodiment, a total of six photovoltaic panels 4 structures can be arranged on the nine tracks 2 .

[0043] In this embodiment, the pressure blocks 32 provided on the legs 3 on the rails 2 in the left and right slots 112 on the sub-float 111 are side pressure blocks 324, which have only one clamping portion 321, while the pressure blocks 32 provided on the legs 3 on the rails 2 in the middle slot 112 are middle pressure blocks 325, which have clamping portions 321 on both sides of the left and right sides, so as to press and fix the edges of the adjacent long sides 43 of the left and right photovoltaic panels 4.

[0044] Moreover, two adjacent photovoltaic panels 4 on the left and right can be assembled simultaneously, and the adjacent long sides 43 of the two adjacent photovoltaic panels 4 can share a limiting plate 33 , on which two first connection holes 331 spaced apart from each other are provided.

[0045] See also Figure 9 and Figure 10 In 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. Furthermore, the height A1 of the rail 2 within the central slot 112 is higher than the height A2 of the rail 2 within the left and right slots 112, ensuring that the upper surface of the central rail 2 and the upper surfaces of the left and right rails 2 remain on the same horizontal plane. This not only improves the support force of the rail 2 shared between the two photovoltaic panels 4, but also ensures that the rail 2 in the middle of the sub-float 111 bears more weight, bringing the force-bearing point of the sub-float 111 closer to the center, thus further stabilizing the floating system formed by the entire float 111.

[0046] In this embodiment, the float 1 may also 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 on the left and right sides. The front and rear ends of the two 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, and the top surfaces of the left float assembly 13 and the right float assembly 14 can also constitute a maintenance passage.

[0047] The left and right float assemblies 13 and 14 of this embodiment each include eight side floats 113. Each side float 113 is adjacently spaced front to back and can be connected and fixed at its top by two connecting rails 114 spaced left and right. The connecting rails 114 can be received in connecting grooves 115 recessed in the top surfaces of the side floats 113. The float 1 is quick and easy to assemble.

[0048] Example 2 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 being that the photovoltaic panels 4 in this embodiment have two rows distributed front and back, each row of photovoltaic panels 4 has six photovoltaic panels 4, for a total of twelve photovoltaic panels 4.

[0049] The left float assembly 13 and the right float assembly 14 of this embodiment both include thirteen side floats 113, and two rows of photovoltaic panels 4 are arranged on nine tracks 2 between the front float assembly 11 and the rear float assembly 12 with a front-to-back interval, that is, two photovoltaic panels 4 with a front-to-back interval can be installed between two tracks 2 of the three tracks 2 on each float 1.

[0050] This shows that the number of photovoltaic panels 4 is not limited to six or twelve, nor is it limited to a single row distributed left and right, but can also be multiple rows distributed front and back, and can be adjusted according to actual needs and the size of the photovoltaic panels 4.
