Description

Technical Field

[0001] The present application relates to the field of water photovoltaic technology, and more specifically, to a floating photovoltaic platform and a photovoltaic system. Background Art

[0002] Photovoltaic power generation, with its natural and clean properties, is considered a green alternative to fossil fuels in the 21st century. Photovoltaic panels receive sunlight and generate electricity through the photoelectric effect. As the photovoltaic industry expands, land resources are becoming scarce. To address this issue, floating photovoltaic power generation has emerged. Floating photovoltaics are a key branch of the photovoltaic industry and are attracting considerable attention. Research has shown that floating photovoltaics are more efficient than ground-based photovoltaics and offer numerous advantages, such as reducing water evaporation and inhibiting algae growth.

[0003] Combine Figure 1 In traditional technology, the operation and maintenance channel of the photovoltaic system consists of a long float 10 and a short float 11. The short float 11 is connected to the photovoltaic float installed with the photovoltaic panel 20. The long float 10 is connected between two adjacent short floats 11, and between the short float 11 and the junction box float 12. Since the long float 10 needs to meet the spatial layout of the photovoltaic panel 20, the extended length of the long float 10 is greater than the short float 11. This results in a larger gap a between the junction box float 12 and the photovoltaic panel 20, which in turn reduces the installed capacity of the photovoltaic system and the power density, and poses certain safety hazards.

[0004] Therefore, how to improve the power density of water photovoltaic systems has become a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0054] The core of this application is to disclose a floating photovoltaic platform to improve the power density of the water photovoltaic system.

[0055] Another core of this application is to disclose a photovoltaic system including the above-mentioned floating photovoltaic platform.

[0056] The following describes the embodiments with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the contents of the utility model described in the claims. Furthermore, the entire contents of the configurations shown in the following embodiments are not limited to those necessary for the solutions of the utility model described in the claims. It should be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings. The embodiments and features in the embodiments of this application may be combined with each other unless there is a conflict.

[0057] For ease of expression, Figure 2 , the arrangement of the floating bodies along the first direction is called a "column", and the arrangement along the second direction is called a "row", and the first direction is perpendicular to the second direction.

[0058] Combine Figure 2-Figure 12 The floating photovoltaic platform disclosed in this application includes a photovoltaic float array 100 , a walkway float 200 , an equipment float array 300 and a first connection float 400 .

[0059] The photovoltaic float arrays 100 are arranged in parallel and spaced apart rows. Each row 100 includes a plurality of float units 110 connected sequentially along a first direction. Along a second direction perpendicular to the first direction, the float units 110 of each row 100 are arranged in a one-to-one correspondence. The float units 110 are integrally structured and include a walkway 111 and two support units 112. The two support units 112 are spaced apart and located on a first side of the walkway 111, for mounting the photovoltaic modules 500. The second side of the walkway 111 aligns with the two support units 112 of adjacent float units 110 in the photovoltaic float array 100.

[0060] Combine Figure 2 There are multiple walkway floats 200, which are arranged between two adjacent rows of photovoltaic floats 100, and the two ends of the walkway floats 200 are respectively connected to the walkway parts 111 of the float units 110 on the two adjacent rows of photovoltaic floats 100. The walkway floats 200 and the walkway parts 111 together constitute an operation and maintenance channel for operation and maintenance personnel to move.

[0061] The equipment float array 300 is arranged parallel to and at intervals with the photovoltaic float array 100, and includes a plurality of second connection floats 320 and a plurality of equipment floats 310. The second connection floats 320 and the equipment floats 310 are alternately arranged and connected along a first direction, and photovoltaic equipment such as junction boxes are used to be set on the equipment floats 310; along the second direction, the second connection floats 320 of each equipment float array 300 are arranged one-to-one with the walkway portions 111 of the float units 110 of the photovoltaic float array 100.

[0062] The first connecting float 400 is connected between the second connecting float 320 of the equipment float array 300 and the walkway portion 111 of the float unit 110 of the photovoltaic float array 100, and along the second direction, the extension length of the first connecting float 400 is less than the extension length of the walkway float 200, that is, the first connecting float 400 is connected to the second connecting float 320 of the equipment float array 300 and the walkway portion 111 of the float unit 110 of the photovoltaic float array 100. Figure 2 、 Figure 7 and Figure 9 , D21 is greater than D31.

[0063] This application has at least the following beneficial effects:

[0064] (1) The walkway portion 111 and the support portion 112 of the float unit 110 are integrally formed, and the walkway portion 111 can be used as part of the operation and maintenance channel, which is equivalent to the float unit 110 integrating the functions of the light float and the walkway float. It has a simple structure, is easy to process, and can reduce a certain amount of material cost.

[0065] (2) Along the first direction, the support portions 112 and the walkway portions 111 on each photovoltaic float column 100 are arranged alternately, so that both ends of each support portion 112 can be affected by the buoyancy of the walkway portion 111, thereby reducing the difference in the installation inclination angles of different rows of photovoltaic components on the float unit 110 in the multi-row arrangement scheme in traditional technology, thereby ensuring the power generation of the photovoltaic system.

[0066] (3) The photovoltaic float array 100 and the equipment float array 300 are connected by extending the first connecting float 400, which is shorter than the walkway float 200. This effectively reduces the distance between the photovoltaic float array 100 and the equipment float array 300 (b<a), thereby improving the installed capacity and power density of the photovoltaic system.

[0067] The floating buoys 110 of the floating photovoltaic platform disclosed in this application can be arranged in a single row or in multiple rows, that is, one row of walkway floats 200 can correspond to one or more rows of buoys 110. Figure 5 A mixed arrangement of single and double rows is shown in FIG.

[0068] In one embodiment, the walkway floats 200 are connected one-to-one between the walkway portions 111 of the float units 110 of two adjacent photovoltaic float columns 100 , that is, one row of walkway floats 200 corresponds to one row of float units 110 .

[0069] At this time, along the first direction, the extension length of the walkway portion 111 is equal to or close to the extension length of the walkway float 200, so that the width of the operation and maintenance channel formed by the support portion 112 and the walkway float 200 is consistent at all locations, thereby improving the safety of the operation and maintenance personnel.

[0070] In another embodiment, the float units 110 on the photovoltaic float column 100 are respectively the first float and the second float. Along the first direction, at least one second float is connected between two adjacent first floats. The walkway floats 200 are connected between the walkway portions 111 of the first floats of two adjacent photovoltaic float columns 100, so that one row of walkway floats 200 corresponds to at least two rows of float units 110.

[0071] Among them, along the first direction, the extension length of the walkway portion 111 of the first floating body is equal to or close to the extension length of the walkway floating body 200, that is, combined with Figure 2 、 Figure 5 and Figure 7 , D11 is equal to D22, so that the width of the operation and maintenance channel formed by the support portion 112 of the first floating body and the walkway floating body 200 is consistent at all locations; along the first direction, the extension length of the walkway portion 111 of the second floating body is less than the extension length of the walkway floating body 200, that is, combined with Figure 2 、 Figure 6 and Figure 7 , D12 is less than D22. Figure 4 , Figure 4 The float monomers 110 used in the Figure 6 The second buoy shown in Figure 1 does not function as an operation and maintenance passage, allowing for a narrower width, thereby reducing production costs. This effectively shortens the distance between adjacent rows of float units 110, thereby increasing installed capacity. The combination of the first and second buoys ensures the safety of the operation and maintenance passage while reducing production costs.

[0072] In one embodiment, combining Figure 5 , both ends of the walkway portion 111 are provided with a first rectangular connecting plate, the first connecting plate and the walkway portion 111 are an integrated structure, and both ends of the first connecting plate along the first direction are provided with a first connecting hole 113; combined Figure 1 and Figure 8 A rectangular second connecting plate 210 is provided at both ends of the walkway float 200. The second connecting plate 210 and the walkway float 200 are integrally formed, and a second connecting hole 211 is provided at both ends of the second connecting plate 210 along the first direction. The first connecting hole 113 is connected to the second connecting hole 211 in a one-to-one correspondence. The first and second connecting plates 210 are arranged in parallel and overlapped. This overlapping connection of the rectangular first and second connecting plates 210 can effectively prevent water splashing at the connection point between the two. The corners of the rectangular first and second connecting plates 210 can be rounded.

[0073] In a further optimization, a first boss is provided on the side of the first connecting plate facing away from the second connecting plate 210. The first boss is positioned between the two first connecting holes 113 and is integral with the first connecting plate. A second boss 220 is provided on the side of the second connecting plate 210 facing away from the first connecting plate. The second boss 220 is integral with the second connecting plate 210 and is positioned between the two second connecting holes 211. The provision of the first and second bosses 220 effectively increases the structural strength of the first and second connecting plates 210 and enhances the buoyancy of the floating photovoltaic platform.

[0074] In order to facilitate the overlapping connection between the walkway section 111 and the walkway float 200, the third direction is defined as the direction perpendicular to the plate surface of the first connecting plate. Along the third direction, the two first connecting plates on each walkway section 111 are arranged in parallel and staggered, and the two second connecting plates 210 on each walkway float 200 are arranged in parallel and staggered.

[0075] In the present application, the float monomer 110 is a U-shaped open structure as a whole. It is defined that each float monomer 110 on the photovoltaic float column 100 is arranged with its opening facing the positive direction of the first direction. Then, the float monomer 110 located at the upper end of the positive direction of each photovoltaic float column 100 is notched. Since the support portion 112 of the float monomer 110 is only provided with a walkway portion 111 on one side, this will cause the two ends of the support portion 112 to be unevenly stressed and tilted. In order to avoid this situation, the support portion 112 is provided with a walkway portion 111 on one side. Figure 2 The photovoltaic floating body array 100 further includes a third connecting floating body 120 .

[0076] Specifically, the support portion 112 of a float unit 110 at the first end of a photovoltaic floating array 100 is connected to the walkway portion 111 of an adjacent float unit 110. The two support portions 112 of a float unit 110 at the second end of the photovoltaic floating array 100 are connected via a third connecting float 120. The third connecting float 120 applies a corresponding force to the support portion 112 to ensure uniform force on the float units 110. The third connecting floats 120 of two adjacent photovoltaic floating arrays 100 are connected via a walkway float 200.

[0077] Combine Figure 5 Each float unit 110 is provided with a support connection portion 114 for connecting to another float unit 110 or a third connection float 120. Support connection holes are defined in the support connection portion 114. The third direction is defined as perpendicular to both the first and second directions. The support connection portions 114 on the two support portions 112 of the same float unit 110 are staggered along the third direction to improve connection reliability.

[0078] The structures of the first, second, and third connecting buoys 400, 320, and 120 can be consistent to facilitate assembly and reduce production costs. Along the first direction, the extended lengths of the first, second, and third connecting buoys 400, 320, and 120 are approximately equal to or equal to the length of the walkway buoy 200, improving safety for maintenance personnel.

[0079] Combine Figure 11 The first connection float 400 is provided with a third connection plate 410 at both ends. The third connection plate 410 is provided with two third connection holes 411. Figure 2 The first end of the first connecting float 400 is used to connect to the walkway portion 111 or the third connecting float 120, and the second end is used to connect to the second connecting float 320. In order to simplify the installation, the connection structure and connection method of the first connecting float 400 and the walkway portion 111 or the third connecting float 120, as well as the connection structure and connection method of the first connecting float 400 and the second connecting float 320 can be consistent with the connection structure and connection method of the walkway portion 111 and the walkway float 200, and will not be repeated here.

[0080] Further, combined with Figure 10 and Figure 11 In order to simultaneously take into account the connection with the support connection part 114, the first connection float 400 is provided with an installation groove on the third connection plate 410. The installation groove corresponds to the position of the third connection hole 411 one by one and is located on both sides of the third connection plate 410. The installation groove forms a step-like structure for the support connection part 114 to be embedded, and after embedding, the third connection hole 411 is connected to the support connection hole.

[0081] The walkway portion 111 has a walking plane for operation and maintenance personnel to walk on. In actual use scenarios, the walking plane is approximately parallel to the horizontal plane. In order to allow each photovoltaic module 500 to be tilted and arranged on a floating photovoltaic platform suspended on the water surface and absorb maximum light, the surface of the support portion 112 used to support the photovoltaic module 500 is defined as the supporting plane. The supporting plane is parallel to or has an angle with the walking plane. Specifically, in combination with Figure 5 When the support plane is parallel to the walking plane, a bracket connecting portion 115 for mounting a bracket assembly can be protruded from the support portion 112, and the bracket assembly is installed on the photovoltaic assembly 500 to form a corresponding installation angle; Figure 13 When the supporting plane and the walking plane have an angle, a photovoltaic mounting portion is provided on the supporting portion 112. The supporting plane provides the required installation inclination angle of the photovoltaic component 500. The photovoltaic component 500 can be directly arranged on the supporting plane and connected and fixed through the photovoltaic mounting portion.

[0082] The structure of the bracket connection part 115 and the photovoltaic installation part includes but is not limited to connecting ears; the bracket connection part 115 and the photovoltaic installation part are an integrated structure with the support part 112.

[0083] Combine Figure 12 A connection lug connected to the second connection floating body 320 is provided on the equipment floating body 310, and a fourth connection hole 311 is opened on the connection lug for bolt connection to the second connection floating body 320.

[0084] The photovoltaic system disclosed herein includes a photovoltaic module 500, a light-floating device, and the aforementioned floating photovoltaic platform. The photovoltaic module 500 is mounted on a support 112, and the photovoltaic device is mounted on a floating device 310. The photovoltaic device includes a combiner box. Due to the inclusion of the aforementioned photovoltaic module 500, the system also possesses the aforementioned structure and benefits. Other structural features are referenced to the prior art and will not be further described here.

Various modifications to these embodiments will be obvious to professionals and technicians in this field, and the general principles defined in this article can be implemented in other embodiments without departing from the spirit or scope of this application. The specific technical means in some embodiments may be incorporated into another embodiment in part or in whole, unless expressly excluded by another embodiment. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
