Detailed Implementation
[0029] The core of this application is to provide a water surface photovoltaic system that enhances the connection strength between floating bodies while simplifying the installation process and reducing costs.
[0030] 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. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0031] With the rapid development of the photovoltaic industry, large-scale photovoltaic power plants are growing rapidly, especially floating photovoltaic power plants. Because they are suitable for various scenarios such as drinking water reservoirs, hydropower station reservoirs, nearshore waters and extremely cold regions, they have been widely recognized in terms of safety, reliability and environmental protection, and have become an important future development direction for the photovoltaic industry.
[0032] Traditional floating hydroelectric power plants are prone to loosening and breakage of their floating body connection components under the long-term impact of wind, waves, currents, and water level fluctuations, leading to connection failure between the floating bodies. To ensure the reliability of the connection between the floating bodies, metal rods are usually added to the connection points to reinforce them. However, this method is not only cumbersome to install, but also increases costs.
[0033] Therefore, such as Figure 1 As shown in the figure, this application discloses a water surface photovoltaic system 100, including a float 10. Multiple lugs 11 on the float 10 are connected and fixed by fasteners 12, thereby enhancing the connection strength between the floats 10. Furthermore, no additional parts are required, simplifying the installation process and reducing costs.
[0034] The following will combine Figures 1 to 8 The surface photovoltaic system 100 disclosed in the embodiments of this application will be explained and described in detail.
[0035] Among them, such as Figure 1 , Figure 4 and Figure 6 As shown, multiple floats 10 can be used, and each float 10 is provided with at least two spaced lugs 11. That is, the number of lugs 11 provided on the float 10 can be two, three or more, and the lugs 11 can extend toward one side of the adjacent float 10. At the same time, mounting holes can be opened on the lugs 11. When connecting two adjacent floats 10, the lugs 11 of the two adjacent floats 10 can be stacked and fastened by bolts or other fasteners 12 passing through the mounting holes on the lugs 11 and locking them with lock nuts to achieve the connection and fixation between the lugs 11 of the two adjacent floats 10. This allows for quick installation between the two adjacent floats 10, which not only enhances the connection strength between the floats 10, but also eliminates the need for additional parts, simplifies the installation process, and reduces costs.
[0036] In some embodiments, the number of lugs 11 provided on the connecting side of the float 10 can be three, and the three lugs 11 are located on the same plane. At the same time, the three lugs 11 can be evenly distributed at intervals to ensure the uniformity of force. This allows the connection strength between two adjacent floats 10 to be improved by passing multiple bolts or other fasteners 12 through the mounting holes on the lugs 11 and locking them with lock nuts when connecting adjacent floats 10, thereby improving the reliability of the photovoltaic array on the water surface.
[0037] In some embodiments, such as Figure 1 , Figure 4 and Figure 6As shown, the float 10 may include a connecting float 13, a walkway float 14, a main float 15, and a manifold float 16. Any two of the walkway float 14, main float 15, and manifold float 16 can be connected by at least one connecting float 13. Specifically, two main floats 15 can be connected by one or more connecting floats 13, or two walkway floats 14 can be connected by one or more connecting floats 13, or two manifold floats 16 can be connected by one or more connecting floats 13, or a walkway float 14 and a main float 15 can be connected by one or more connecting floats 13, or a manifold float 16 and a walkway float 14 can be connected by one or more connecting floats 13.
[0038] In some embodiments, such as Figure 1 , Figure 4 and Figure 6 As shown, the water surface photovoltaic system may also include photovoltaic modules 20, and the photovoltaic modules 20 are disposed on at least one side of the main floating body 15. That is, the photovoltaic modules 20 may be disposed on one side of the main floating body 15 or on both sides of the main floating body 15. At the same time, the photovoltaic modules 20 and the ear plates 11 are located on different sides of the main floating body 15 to avoid interference with the installation of the photovoltaic modules 20.
[0039] In some embodiments, such as Figure 2 , Figure 5 and Figure 8 As shown, the main float 15 may be provided with cantilevered lugs 151 for mounting photovoltaic modules 20, so that the photovoltaic modules 20 can be connected and fixed to the cantilevered lugs 151 by bolts or other fasteners. Two cantilevered lugs 151 may be provided on one side of the main float 15, and the height of the cantilevered lugs 151 is higher than the height of the ear plate 11. That is, the distance between the upper surface of the cantilevered lugs 151 and the water surface is greater than the distance between the upper surface of the ear plate 11 and the water surface. This prevents the photovoltaic modules 20 from falling into the water under the action of water erosion, thus protecting them from damage and providing better protection.
[0040] In some embodiments, such as Figure 1 , Figure 4 and Figure 6 As shown, the connecting float 13, walkway float 14, main float 15, and combiner box float 16 can all adopt a rectangular structure. The horizontal cross-sectional area of the walkway float 14 and the combiner box float 16 is larger than that of the connecting float 13, so as to provide greater buoyancy for operation and maintenance and combiner box equipment. At the same time, the area enclosed by the outer contour of the main float 15 is larger than the area enclosed by the outer contour of the walkway float 14 and the combiner box float 16, so that the main float 15 can support the photovoltaic module 20, thereby providing greater buoyancy for the photovoltaic module 20.
[0041] In some embodiments, such as Figure 2 , Figure 3 and Figure 5 As shown, the main float 15 may include a float body 152 and a weight-reducing opening 153 disposed on the float body 152. The weight-reducing opening 153 is adapted to the shape of the float body 152, and the size of the weight-reducing opening 153 is maximized while ensuring the strength of the float body 152, so as to reduce the weight of the main float 15 and thus provide greater buoyancy for the photovoltaic module 20, ensuring the stability of the water surface photovoltaic system 100. Meanwhile, an ear plate 11 is provided on at least one side of the float body 152, i.e., an ear plate 11 is provided on one side of the float body 152. Figure 8 As shown, ear plates 11 can also be provided on both sides of the float body 152, such as... Figure 3 As shown, this is to achieve the connection and fixation of the main floating body 15.
[0042] In some embodiments, such as Figure 1 , Figure 4 and Figure 6 As shown, the walkway float 14 may include multiple walkway floats, and each walkway float 14 forms at least two parallel maintenance walkways 141. That is, the number of maintenance walkways 141 formed by each walkway float 14 can be two, three or more parallel walkways. Furthermore, multiple main floats 15 are spaced apart between two adjacent maintenance walkways 141 along a direction parallel to the maintenance walkway 141. That is, two, three or more main floats 15 can be spaced apart between two adjacent maintenance walkways 141 along a direction parallel to the maintenance walkway 141. Multiple junction box floats 16 can be used, that is, two, three or more junction box floats 16 can be used. Each junction box float 16 is connected between two adjacent maintenance walkways 141, and at least one junction box float 16 can be set on both sides of each main float 15, that is, one or more junction box floats 16 can be set on both sides of each main float 15, and each main float 15 is located in the area enclosed by each junction box float 16 and the maintenance walkway 141.
[0043] In some embodiments, such as Figures 1 to 8 As shown, adjacent walkway floats 14 on each maintenance walkway 141 can be connected by connecting floats 13. Each end of the main float 15 can have three lugs 11. Simultaneously, the connecting float 13 can have three lugs 11 adapted to the main float 15, perpendicular to the maintenance walkway 141. This allows the lugs 11 on the connecting float 13 and the main float 15 to be stacked, and multiple bolts or other fasteners 12 to pass through the lugs 11 on both the connecting float 13 and the main float 15, and then locked in place with lock nuts. Using three lugs 11 to connect and fix the floats 10 results in higher connection strength, effectively improving the reliability of the water surface photovoltaic array.
[0044] In some embodiments, such as Figure 1 , Figure 4 and Figure 6 As shown, the connecting float 13 and the walkway float 14 can be an integrated structure. Of course, the connecting float 13 and the walkway float 14 can also be connected by ear plates 11, that is, the ear plates 11 of the connecting float 13 and the ear plates 11 of the walkway float 14 can be stacked and connected and fixed by fasteners 12 such as bolts, so as to realize the flexible distribution of the photovoltaic array on the water surface.
[0045] In some embodiments, such as Figure 4 and Figure 6 As shown, at least two main floating bodies 15 can be installed between two adjacent maintenance walkways 141 in a direction perpendicular to the maintenance walkways 141. That is, two main floating bodies 15 can be installed between two adjacent maintenance walkways 141 in a direction perpendicular to the maintenance walkways 141. Figure 4 As shown, more than two main floating bodies 15 can also be set, such as three or four, etc. Figure 6 As shown, two adjacent main floats 15 can be directly connected by three lugs 11, or they can be connected by one or more connecting floats 13.
[0046] In some embodiments, such as Figure 4 and Figure 6 As shown, at least two main floating bodies 15 arranged in a direction perpendicular to the maintenance walkway 141 are of an integral structure, that is, the two main floating bodies 15 arranged in a direction perpendicular to the maintenance walkway 141 can adopt an integral structure, such as... Figure 4 As shown, the three main floating bodies 15 arranged in the direction perpendicular to the maintenance walkway 141 can also adopt an integrated structure, or two, three, or more sets of integrated main floating bodies 15 can be arranged in the direction perpendicular to the maintenance walkway 141, and the number of main floating bodies 15 in each set of integrated structures can be two, three, etc., as shown. Figure 6 As shown, two adjacent sets of integrated main floats 15 can be connected by one or more connecting floats 13.
[0047] In some embodiments, such as Figure 1 As shown, between two adjacent maintenance walkways 141, a main floating body 15 can be set in a direction perpendicular to the maintenance walkway 141, and multiple main floating bodies 15 can be set in a direction parallel to the maintenance walkway 141. That is, when the photovoltaic modules 20 of the water surface photovoltaic system 100 are distributed in a single row, the three ear plates 11 at both ends of a single main floating body 15 are respectively connected and fixed to the connecting floating bodies 13 in the two maintenance walkways 141 by fasteners such as bolts 12, thereby improving the connection strength and effectively improving the reliability of the water surface photovoltaic array.
[0048] In some embodiments, such as Figure 4 As shown, between two adjacent maintenance walkways 141, two main floating bodies 15 can be set in a direction perpendicular to the maintenance walkway 141. The two main floating bodies 15 set in a direction perpendicular to the maintenance walkway 141 can adopt an integrated structure. In addition, multiple sets of integrated main floating bodies 15 can be set in a direction parallel to the maintenance walkway 141. That is, when the photovoltaic modules 20 of the water surface photovoltaic system 100 are arranged in double rows, the three ear plates 11 at both ends of each set of integrated main floating bodies 15 are connected and fixed to the connecting floating bodies 13 in the two maintenance walkways 141 by fasteners such as bolts 12, thereby improving the connection strength and effectively improving the reliability of the water surface photovoltaic array.
[0049] In some embodiments, such as Figure 6 As shown, four main floating bodies 15 can be set between two adjacent maintenance walkways 141 along a direction perpendicular to the maintenance walkway 141. At the same time, every two main floating bodies 15 along the direction perpendicular to the maintenance walkway 141 can adopt an integrated structure, that is, two sets of integrated main floating bodies 15 can be set along the direction perpendicular to the maintenance walkway 141, and multiple sets of main floating bodies 15 can be set along the direction parallel to the maintenance walkway 141. That is, when the photovoltaic modules 20 of the water surface photovoltaic system 100 are arranged in four rows, the two adjacent sets of integrated main floating bodies 15 along the direction perpendicular to the maintenance walkway 141 can be connected by connecting floats 13. Specifically, the three ear plates 11 at both ends of each set of integrated main floating bodies 15 along the direction perpendicular to the maintenance walkway 141 are respectively connected and fixed to the connecting floats 13 and the connecting floats 13 in the maintenance walkway 141 by fasteners such as bolts 12, thereby improving the connection strength and effectively improving the reliability of the water surface photovoltaic array.
