[0039] This utility model discloses a floating system for a floating photovoltaic power station, which reduces the number of connecting floats during the assembly of the main float, thereby lowering processing costs. Furthermore, this utility model also discloses a floating photovoltaic power station with the aforementioned floating system.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0042] like Figures 1 to 4 As shown in the embodiment of this application, the floating photovoltaic power station includes: photovoltaic modules 100 and a floating system 200, wherein the floating system 200 includes a main float 201 and a connecting float 202. The photovoltaic modules 100 are arranged in a single row, that is, each row of photovoltaic modules 100 along the first direction has only one photovoltaic module 100 along the second direction, and the first direction is perpendicular to the second direction.

[0043] Multiple main floats 201 are arranged side-by-side along a first direction, while the main floats 201 arranged along a second direction are staggered. Adjacent main floats 201 along the first direction support the photovoltaic module 100, and there is a gap between adjacent main floats 201 along the first direction. The size of the gap can be the distance between the support rods of the bracket supporting the photovoltaic module 100. This can be understood as follows: the photovoltaic module 100 is connected to the bracket, and the bracket has at least two support rods, which are distributed and installed on adjacent main floats 201.

[0044] The main buoy 201 is I-shaped, consisting of a first section 2011 and a second section 2012. There are two first sections 2011, which are connected to form an I-shape through the second section 2012.

[0045] Both first segments 2011 extend along a first direction, and the second segment 2012 extends along a second direction. Each end of the second segment 2011 is connected to a first segment 2011. The dimension of the first segment along the first direction is greater than the dimension of the second segment 2012 along the first direction, so that the main float 201 is formed in an I-shape. Optionally, the dimension of the first segment 2011 along the second direction is smaller than the dimension of the second segment 2012 along the second direction.

[0046] The first segment 2011 has a first connecting plate 20111 and a first mounting base 20112 at both ends along the first direction.

[0047] The first connecting plate 20111 can be connected to the first connecting plate 20111 of the main float 201, which is staggered along the second direction; or, the first connecting plate 20111 can be connected to the connecting float 202, which is arranged along the first direction. Specifically, the first segment 2011 at the middle end of the main float 201 located at the end of the second direction is connected to the first segment 2011 at the end of the adjacent main float 201 along the first direction via the connecting float 202, while the first segments 2011 at other positions are connected to the first segments 2011 of the staggered main float 201.

[0048] As can be seen from the above connection relationship, in this embodiment of the application, the main float 201 and the connecting float 202 are only needed to be connected to form the required floating system 200. The connecting float 202 is only used at the end of the floating system 200 in the second direction, and no other type of float is needed at other positions of the floating system 200. Therefore, the number of connecting floats 202 can be effectively reduced, thereby reducing costs.

[0049] The connection methods between the first segment 2011 and the connecting float 202 in this embodiment include, but are not limited to, threaded connection, welding, and snap-fit. Optionally, the connection method between the first segment 2011 and the first segment 2011 of the adjacent main float 201 is the same as the connection method between the first segment 2011 and the connecting float 202. The following description uses the connection method between the first segment 2011 and the connecting float 202 as an example. The connection method between the first segment 2011 and the first segment 2011 of the adjacent main float 201 is described in the following description.

[0050] Combination Figure 9 As shown, the first segment 2011 has first connecting plates 20111 at both ends along the first direction. Optionally, each end has two first connecting plates 20111, and each first connecting plate 20111 has a first mounting hole. The connecting float 202 has second connecting plates 2021 at both ends along the first direction. Optionally, each end has two second connecting plates 2021, and each second connecting plate 2021 has a mounting hole. During the connection process between the first segment 2011 of the main float 201 and the connecting float 202, the two first connecting plates 20111 at one end of the first segment 2011 along the first direction overlap with the two second connecting plates 2021 at one end of the connecting float 202 along the first direction, and are connected to the first mounting hole and the mounting hole through a connector, thereby realizing the connection between the main float 201 and the connecting float 202.

[0051] In some embodiments, one of the two first connecting discs 20111 at one end of the first segment 2011 along the first direction overlaps above the corresponding second connecting disc 2021 of the connecting float 202, and the other second connecting disc 2021 of the connecting float 202 overlaps above the other of the two first connecting discs 20111. It can be understood that at least one first connecting disc 20111 overlaps above the second connecting disc 2021. The number of first connecting discs 20111 and second connecting discs 2021 can be set according to different needs, including but not limited to two.

[0052] By adopting the above connection method, the stability of the connection between the main float 201 and the connecting float 202 can be improved, as well as the stability of the connection of the main float 201, thereby improving the impact resistance of the floating system 200 during the rising and falling of the water surface.

[0053] It should be noted that the main float 201 at the second end of the floating system 200 is connected to the connecting float 202 along the first direction. It can be understood that the first segment 2011 of the edge of the main float 201 at the second end of the floating system 200 is connected to the first segment 2011 of the edge of the adjacent main float 201 along the first direction via the connecting float 202. The first connecting plate 20111 of the other main floats 201 of the floating system 200 is connected to the first connecting plate 20111 of the main floats 201 arranged in a staggered manner along the second direction.

[0054] First mounting bases 20112 are arranged at both ends of the first segment 2011 along the first direction. For example, a first mounting base 20112 is arranged at both ends of the first segment 2011 along the first direction, and the first mounting bases 20112 are arranged close to the second segment 2012.

[0055] In the main float 201 arranged along the first direction, the two first mounting seats 20112 of the main float 201 and the two first mounting seats 20112 of the adjacent main float 201 are used to support the photovoltaic module 100. It can be understood that the photovoltaic module 100 is connected to the first mounting seats 20112 of the two adjacent main floats 201 through the bracket.

[0056] Using the above connection method, a single row of photovoltaic modules 100 can be installed on the floating system 200. It can be understood that only one row of photovoltaic modules 100 is installed on each row of main floats 201 along the first direction. Combined with the arrangement of the main floats 201, the photovoltaic modules 100 arranged along the second direction are staggered.

[0057] like Figures 5 to 10As shown, the floating photovoltaic power station provided in this application includes: photovoltaic modules 100 and a floating system 200, wherein the floating system 200 includes a main float 201 and a connecting float 202. The photovoltaic modules 100 are arranged in a double row, that is, two rows of photovoltaic modules 100 arranged parallel to the first direction and facing each other along the second direction form a row of photovoltaic modules 100.

[0058] The main float 201 includes two first main floats 203, wherein the first main float 203 is I-shaped and includes a first segment 2011, a third segment 2032 and a fourth segment 2033.

[0059] The first segment 2011 is the first segment 2011 disclosed in the above embodiments. The first segment 2011 has a first connecting plate 20111 and a first mounting base 20112. The shape and arrangement of the first connecting plate 20111 and the first mounting base 20112 can be found in the above embodiments.

[0060] The fourth segment 2033 and the first segment 2011 both extend along the first direction. Optionally, the dimension of the fourth segment 2033 along the first direction is smaller than the dimension of the first segment 2011 along the first direction, and the dimension of the fourth segment 2033 along the second direction is smaller than the dimension of the first segment 2011 along the second direction. The third segment 2032 extends along the second direction, and one end of the third segment 2032 along the second direction connects to the first segment 2011, and the other end connects to the fourth segment 2033, so that the first main float 203 is formed in an I-shape. Optionally, the first segment 2011, the third segment 2032, and the fourth segment 2033 are integrally formed, and the specific dimensions and shapes of the first segment 2011, the third segment 2032, and the fourth segment 2033 can be set according to different needs, and all are within the protection range.

[0061] The fourth segment 2033 has a third connecting plate 20331 and a second mounting base 20332. In the floating system 200, two first main floats 203 are arranged along a second direction, and the third connecting plates 20331 of the two first main floats 203 are connected, thereby realizing the connection of the two first main floats 203, so that the two first main floats 203 are symmetrically arranged about the connection point of the third connecting plate 20331.

[0062] It should be noted that after the two first main floats 203 are symmetrically connected, both ends along the second direction are first segments 2011. This can be understood as the two first main floats 203 being spliced ​​together to form the structure of the main float 201 in the above embodiment. The connection relationship of the main floats 201 can be found in the content disclosed in the above embodiment. For example, multiple main floats 201 are arranged side by side along the first direction, and the main floats 201 arranged along the second direction are staggered.

[0063] The first mounting base 20112 and the second mounting base 20332 of the adjacent first main floats 203 along the first direction are used to connect with the bracket of the photovoltaic module 100. This can be understood as follows: the photovoltaic module 100 is connected to the first mounting base 20112 and the second mounting base 20332 of the two adjacent first main floats 203 via the bracket. Figure 5 and Figure 8 As shown, in the floating system 200 of this application embodiment, the two first main floats 203 connected along the second direction cooperate with the two adjacent first main floats 203 along the first direction to realize the connection of two photovoltaic modules 100. Specifically, the first mounting base 20112 and the second mounting base 20332 of the first main float 203, together with the first mounting base 20112 and the second mounting base 20332 of the adjacent first main floats 203 along the first direction, serve as the mounting base for the photovoltaic modules 100. The two first main floats 203 are connected along the second direction, thereby realizing the arrangement of double-row photovoltaic modules 100.

[0064] The connection method between the first segment 2011 and the connecting float 202 in this application embodiment, as well as the connection method of adjacent first segments 2011, can be referred to the above embodiment content and will not be repeated here.

[0065] The connection methods of the fourth segment 2033 of the adjacent first main float 203 in this application embodiment include, but are not limited to, threaded connection, welding and snap-fit.

[0066] like Figure 10 As shown, the fourth segment 2033 of the first main float 203 has a third connecting plate 20331 at its end along the second direction. Optionally, the fourth segment 2033 has two third connecting plates 20331 at its end along the second direction, and each third connecting plate 20331 has a third mounting hole. During the connection process of the fourth segments 2033 of adjacent first main floats 203, the third connecting plates 20331 of the two overlap and are connected by the third mounting holes of the two through connectors, thereby realizing the connection of the two first main floats 203.

[0067] In some embodiments, among two adjacent first main floats 203, one of the two third connecting plates 20331 of the fourth segment 2033 of one first main float 203 is attached above the corresponding third connecting plate 20331 of the fourth segment 2033 of the other first main float 203, and the other is attached below the corresponding third connecting plate 20331, so as to improve the stability of the connection and improve the impact resistance during the floating process.

[0068] like Figures 11 to 14As shown, the floating photovoltaic power station provided in this application includes: photovoltaic modules 100 and a floating system 200, wherein the floating system 200 includes a main float 201 and a connecting float 202. The photovoltaic modules 100 are arranged in a three-row configuration, that is, three rows of photovoltaic modules 100 arranged parallel to the first direction and facing each other along the second direction form a row of photovoltaic modules 100.

[0069] The main float 201 includes a first main float 203 and a second main float 204, wherein there are two first main floats 203. The first main float 203, the second main float 204 and the first main float 203 are arranged sequentially along the second direction, and the two first main floats 203 are arranged symmetrically about the second main float 204.

[0070] The shape of the first main float 203 is the same as that disclosed in the above embodiments. The two first main floats 203 are symmetrically arranged about the second main float 204, and both ends of the two first main floats 203 along the second direction are first segments 2011. Therefore, it can be understood that after the two first main floats 203 arranged along the second direction are symmetrically arranged, the two ends of the two first main floats 203 form the first segments 2011 at both ends of the main float 201. The connection relationship and arrangement of the main float 201 including the first main float 203 and the second main float 204 with the connecting float 202, as well as the connection relationship and arrangement with other main floats 201, are the same as those in the above embodiments, and will not be repeated here.

[0071] The main float 201 of this application embodiment includes a first main float 203 and a second main float 204. There are two first main floats 203. The first main float 203 and the second main float 204 can be used to connect a photovoltaic module 100, thereby realizing that three photovoltaic modules are arranged facing each other along the second direction, and thus realizing that three rows of photovoltaic modules 100 form a row of photovoltaic modules 100 along the first direction.

[0072] The second main float 204 is I-shaped and includes a fifth section 2041 and a sixth section 2042. There are two fifth sections 2041, which are located at both ends of the sixth section 2042.

[0073] The fifth segment 2041 and the sixth segment 2042 are arranged along the second direction, and the dimension of the fifth segment 2041 along the first direction is larger than the dimension of the sixth segment 2042 along the first direction. Optionally, the dimension of the fifth segment 2041 is the same as the dimension of the fourth segment 2033. It should be noted that the dimension and shape of the sixth segment 2042 in this application can be set according to different needs, and this application does not specifically limit them. The sixth segment 2042 and the two fifth segments 2041 are integrally formed into the second main float 204.

[0074] The fifth segment 2041 has a fourth connecting plate 20411 and a third mounting base 20412 at its end along the second direction.

[0075] During the connection process between the first main float 203 and the second main float 204, the fourth segment 2033 of the first main float 203 is connected to a fifth segment 2041 of the second main float 204. Specifically, the third connecting plate 20331 and the fourth connecting plate 20411 are connected by threaded fittings. It should be noted that the fourth segment 2033 of the first main float 203 and the fifth segment 2041 of the second main float 204 can also be connected by snap-fit, welding, or other connection methods.

[0076] In some embodiments, the fifth segment 2041 has a fourth connecting plate 20411 at both ends along the second direction. The fourth connecting plate 20411 has a fifth mounting hole. During the connection process between the fourth segment 2033 of the first main float 203 and a fifth segment 2041 of the second main float 204, the fourth connecting plate 20411 overlaps with the third connecting plate 20331 of the fourth segment 2033, and the fifth mounting hole coincides with the third mounting hole and is connected by a connector.

[0077] Optionally, during the connection process of the first main float 203 and the second main float 204, one of the two third connecting plates 20331 of the fourth section 2033 of the first main float 203 is attached above the fourth connecting plate 20411 of the fifth section 2041 of the second main float 204, and the other is attached below the corresponding fourth connecting plate 20411, so as to improve the stability of the connection and improve the impact resistance during the floating process.

[0078] Combination Figure 14 As shown, two adjacent first main floats 203 along the first direction can be used to support one photovoltaic module 100, and the third mounting base 20412 of two adjacent second main floats 204 along the first direction can be used to support one photovoltaic module 100. Each group of main floats 201 has two first main floats 203. Therefore, two adjacent groups of main floats 201 can support three photovoltaic modules 100, thereby realizing the three-row arrangement of photovoltaic modules 100.

[0079] It should be noted that, according to the above description of the three-row arrangement of photovoltaic modules 100, when more row arrangements of photovoltaic modules 100 are required, the number of second main floats 204 between the two first main floats 203 arranged along the second direction can be increased.

[0080] As described above, the first main float 203 and the second main float 204 can be spliced ​​together to form the desired shape of the main float 201. This means that the main float 201 does not need to be connected by other connecting floats 202. Only the connecting floats 202 are used at the ends of the floating system 200 along the second direction. Therefore, it is possible to reduce the number of connecting floats 202 and lower costs while also enabling the arrangement of different numbers of photovoltaic modules in a row. This increases the applicability of the main float 201, makes the main float 201 modular, and reduces the development cost of the main float 201.

[0081] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0082] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily 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. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
