[0041] The core of the utility model is to disclose a floating array to reduce the cost of a water surface photovoltaic system.
[0042] Another core of the present invention is to disclose a water surface photovoltaic system including the above-mentioned floating array.
[0043] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the scope of the utility model as set forth in the claims. Furthermore, the entire contents of the components described in the following embodiments are not necessarily required to provide the solutions 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 of the embodiments of the present utility model may be combined with one another unless there is a conflict.
[0044] Combine Figures 1-9 The floating array disclosed in the present invention includes a walkway floating array 100 and a photovoltaic floating array 200. The walkway floating array 100 is a plurality of rows arranged in parallel and at intervals, and each row of the walkway floating array 100 extends along a first direction and is used as an operation and maintenance channel for workers to pass through; the photovoltaic floating array 200 is a plurality of rows extending along the first direction and is arranged between two adjacent rows of the walkway floating array 100. The photovoltaic floating array 200 includes a plurality of photovoltaic floating units arranged at intervals along the first direction. The photovoltaic floating units include a plurality of photovoltaic floating units spaced apart along the first direction. Multiple float units 210 are arranged in a spaced-apart arrangement. Each float unit 210 extends in a second direction perpendicular to the first direction and is elongated. The float units 210 have opposing first and second side surfaces 211 and 212, which are arranged at an angle. Each photovoltaic float unit is configured to correspond one-to-one with a photovoltaic module 300, with the photovoltaic module 300 being mounted on the first side surface 211 of each float unit. The second side surface 212 of the float unit 210 is configured to be submerged in water and provide buoyancy. The angle between the first and second side surfaces 211 and 212 can be adjusted as needed.
[0045] Compared with the prior art, the first side 211 of the floating array disclosed in the present invention, which is arranged tilted relative to the second side 212, can provide the installation inclination angle required by the photovoltaic component 300, thereby eliminating the setting of the bracket system, which greatly reduces the production cost and avoids the corrosion problem of the metal bracket system.
[0046] Specifically, combined Figure 7 and Figure 8The photovoltaic assembly 300 is connected to the photovoltaic float unit through the adapter 230 and the pressure block 220; the adapter 230 is provided with a first bonding surface and a second bonding surface, the first bonding surface is used to bond with the photovoltaic assembly 300, and the second bonding surface is used to bond with the first side surface 211 of the float unit 210 of the photovoltaic float unit. The first bonding surface and the second bonding surface are arranged in parallel or at an angle, and the adapter 230 is connected to the float unit 210, and the pressure block 220 is connected to the adapter 230 and pressed against the photovoltaic assembly 300, thereby realizing the connection between the photovoltaic assembly 300 and the float unit 210.
[0047] The angled first and second mating surfaces of the adapter 230 further adjust the installation angle of the photovoltaic module 300 on the float unit 210. Both the adapter 230 and the pressure block 220 can be made of aluminum alloy, which offers low cost and excellent corrosion resistance. Bolts can be used to secure the adapter 230 to the float unit 210, as well as the pressure block 220 to the adapter 230. The bolt holes on the pressure block 220, adapter 230, and float unit 210 can be waist-shaped for easier assembly.
[0048] The floating body array disclosed in the present invention can be applicable to a single-row system or a multi-row system, that is, one or more rows of photovoltaic floating body rows 200 can be arranged between two adjacent rows of walkway floating body rows 100.
[0049] Specifically, when a row of photovoltaic floats 200 is arranged between two adjacent rows of walkway floats 100 , both ends of each float unit 210 of the photovoltaic floats 200 are respectively connected to the walkway floats 100 located on both sides of the photovoltaic floats 200 .
[0050] When multiple rows of photovoltaic floats 200 are arranged between two adjacent rows of walkway floats 100, a float-enhancing body 240 can be installed between the photovoltaic float units of the two adjacent rows of photovoltaic floats 200. The float-enhancing body 240 extends along a first direction and is connected to the float units 210 of the photovoltaic float units at both ends. It should be noted that the term "adjacent" here refers to two adjacent rows of photovoltaic floats 200 that are not separated by a walkway float 100. The float-enhancing body 240 is used to enhance the buoyancy between the two adjacent rows of photovoltaic floats 200, preventing uneven forces acting on the ends of the float units 210, which could cause the float units 210 and photovoltaic modules 300 to tilt and reduce photovoltaic efficiency.
[0051] Combine Figure 1 and Figure 9 The walkway float array 100 includes a plurality of walkway floats 110 sequentially arranged along a first direction, and two adjacent walkway floats 110 are connected by walkway lugs 111. In the first direction, the extension length of the walkway floats 110 is 1 / 2 of the distance between two adjacent photovoltaic modules 300.
[0052] Combine Figure 4 The structures of the buoyancy-enhancing float 240 and the walkway float 110 can be the same, so as to facilitate preparation using the same model and reduce production costs.
[0053] The array of floats also includes an equipment channel for accommodating photovoltaic equipment, such as combiner boxes. The equipment channel extends along the second direction and is located at the end of the walkway float array 100. Specifically, the equipment channel comprises a plurality of equipment floats 400 sequentially connected along the second direction. Each equipment float 400 extends along the first direction. The structure of the equipment floats 400 and the walkway floats 110 may be the same or different, but preferably the same structure to facilitate manufacturing using the same model and reduce production costs.
[0054] In order to ensure reliable support for the photovoltaic module 300 while reducing production costs, each photovoltaic float unit includes two float units 210 arranged at intervals along the first direction. The first side surfaces 211 of the two float units 210 are located in the same plane and can be supported at both ends of the photovoltaic module 300 respectively.
[0055] Combine Figure 5 and Figure 6 The two ends of the float unit 210 are respectively provided with a first connection portion 213 and a second connection portion 214 for connecting with the adjacent walkway float column 100 or photovoltaic float column 200.
[0056] When the first connection part 213 and the second connection part 214 are both ear-holding structures, the extension directions of the first connection part 213 and the second connection part 214 are parallel to the second side surface 212, and the first connection part 213 and the second connection part 214 are staggered to facilitate overlapping connection with the walkway float column 100, the buoyancy-enhancing float 240, etc.
[0057] The float unit 210 may be provided as an integrated structure, that is, the float unit 210 , the first connecting portion 213 and the second connecting portion 214 may be integrally formed by a mold, which facilitates processing and production.
[0058] The present invention optimizes the structure of the float unit 210 under the premise of ensuring the installation spacing of the photovoltaic modules 300 to avoid shadow blocking. The float unit 210 has its own inclination angle, which can be formed by selecting different sub-inserts during the preparation process.
[0059] It should be noted that the present invention does not make specific restrictions on the material and size parameters of the float monomer 210. During implementation, technicians in this field can adjust the material and size of the float monomer 210 according to various factors such as the load-bearing capacity and installation environment of the float monomer 210 to ensure the load-bearing capacity and service life of the float monomer 210.
[0060] The floating array disclosed in the embodiment of the present utility model can be spliced together using only the above-mentioned float units 210 and the walkway floats 110. The types of float units 210 used are few, easy to identify, and have high installation efficiency, which can save a lot of mold costs. It can be spliced to form a variety of floating array structures that can be installed with photovoltaic modules 300, and corresponding operation and maintenance channels can be formed. The solution is flexible, reliable, and stable.
[0061] The surface photovoltaic system disclosed in the present invention includes multiple photovoltaic modules 300 and the above-mentioned floating body array. Each photovoltaic module 300 corresponds to each photovoltaic floating body unit one by one, and the photovoltaic module 300 is arranged on the first side 211 of the float unit 210 of the photovoltaic floating body unit. Since it includes the above-mentioned floating body array, it also has the above-mentioned structure and beneficial effects. Other structures refer to the existing technology and will not be repeated here.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
