In the field of sea power generation, wind power projects can be used for power generation on the sea, and research on sea photovoltaic power generation is less. At present, the functionality of photovoltaic power generation equipment is relatively single whether on land or on the sea, and due to the large volume of photovoltaic equipment, the sea area occupied is large, especially the sea area covered by the photovoltaic equipment is in an idle or vacant state, and the utilization rate of the sea area is low.

By arranging the photovoltaic component 10 in the offshore area, the sea area can be fully utilized to meet the offshore photovoltaic power generation demand. The breeding component 20 connected with the photovoltaic component 10 is also arranged in the system. By carrying out fishery breeding in the photovoltaic area 100, the sea area can be comprehensively utilized, the integration of the system is improved, the utilization rate of the sea area is improved, and the economy of the system is improved.

[0036] The various parts of the offshore photovoltaic and ocean ranching integrated system provided by the present disclosure will be described in detail below in combination with the drawings:

[0037] In the embodiments provided by the present disclosure, as shown in Figure 1 and Figure 2 The system comprises a plurality of photovoltaic components 10, the plurality of photovoltaic components 10 are arranged in the photovoltaic area 100, each photovoltaic component 10 comprises at least one support structure 11 and a plurality of photovoltaic panels 12, and the photovoltaic panels 12 are used to convert solar energy into electric energy.

[0038] As shown in Figure 3 and Figure 4As shown, the support structure 11 comprises a first support part 111 and a second support part 112, at least part of the first support part 111 is fixed in the sea, at least part of the first support part 111 extends above the sea level, the second support part 112 has a preset distance from the sea level, the second support part 112 is connected with the first support part 111, and a plurality of photovoltaic panels 12 are arranged on the second support part 112.

[0039] The first support part 111 can be composed of a plurality of pile foundations, the axis of each pile foundation is arranged in a direction perpendicular to the sea level, and the axes of the plurality of pile foundations can be parallel or substantially parallel, the pile foundation can be a structure such as a steel pile, a concrete pile or a reinforced concrete pile, and the materials and sizes of the pile foundations in the first support part 111 can be the same or different, for example, which can be determined according to the position of the pile foundation and the size of the load borne.

[0040] As shown, Figure 4 Part of the first support part 111 is fixed in the sea, that is, one end of the pile foundation is sunk or inserted into the sea to fix the position of the pile foundation and make the other end of the pile foundation have a bearing capacity; part of the first support part 111 extends above the sea level, that is, the other end of the pile foundation extends above the sea level to support the second support part 112.

[0041] The first support part 111 can also be a box foundation, a raft foundation or a strip foundation, and other structures having similar functions and effects as the pile foundation can be combined or used alone, but in order to facilitate construction and manufacturing, the pile foundation can be used as the first support part 111. In the following embodiments of the present disclosure, the number of pile foundations in the first support part 111 is four, but it should be understood that when the number or arrangement of the pile foundations in the first support part 111 is changed, the other components in the system of the present disclosure are adjusted accordingly to adapt to the changes in the structure of the pile foundations in the first support part 111, which are all within the protection scope of the present disclosure.

[0042] The second support part 112 can be a grid structure composed of a plurality of truss structures, and the second support part 112 can be a cuboid or a cuboid-like shape, one side of which faces the sea level and is connected with the first support part 111, and the other side of which away from the sea level is provided with photovoltaic panels 12, and the second support part 112 provides support force and laying position for the arrangement of the photovoltaic panels 12.

[0043] The second support part 112 can be parallel or substantially parallel to the sea level, or the second support part 112 can have an included angle with the sea level. Since the photovoltaic panel 12 needs to be arranged according to the angle of the sun, when the second support part 112 has an included angle with the sea level, the absorption and utilization rate of solar energy can be improved. However, if the included angle is too large, the stability of the second support part 112 on the sea will be affected, and if the included angle is too small, the utilization rate of the photovoltaic panel 12 to solar energy will be affected. Therefore, the included angle between the second support part 112 and the sea level can be 15°.

[0044] In order to avoid the second support part 112 and the photovoltaic panel 12 from being eroded by seawater, and to facilitate the installation and maintenance of the support structure 11, a preset interval between the second support part 112 and the sea level is usually required, which is greater than or equal to 1 m, such as 1 m, 2 m, 3 m, 4 m, 5 m, etc. The preset interval can be adjusted according to the specific structure requirements of the support structure 11. In the present disclosure, the preset interval between the second support part 112 and the sea level refers to the distance between the part of the second support part 112 closest to the sea level and the sea level, that is, the minimum distance between the second support part 112 and the sea level.

[0045] In the present disclosure, each photovoltaic assembly 10 can be combined by one support structure 11 and a plurality of photovoltaic panels 12, or can be combined by a plurality of support structures 11 and a plurality of photovoltaic panels 12 according to actual needs. The embodiments of the present disclosure are described by taking the form that one photovoltaic assembly 10 includes one support structure 11 and a plurality of photovoltaic panels 12 as an example, and the total area of the projection of the plurality of photovoltaic panels 12 on the surface of the second support part 112 does not exceed the surface area of the second support part 112, so as to ensure the effective support and fixation of the second support part 112 to the photovoltaic panel 12.

[0046] In the embodiments provided in the present disclosure, as shown in Figure 1 and Figure 2As shown, a plurality of photovoltaic components 10 are arranged in the photovoltaic area 100. The photovoltaic area 100 can include a plurality of sub-photovoltaic areas 101 and a plurality of isolation channels 102, two adjacent sub-photovoltaic areas 101 are isolated by an isolation channel 102, wherein each sub-photovoltaic area 101 is provided with at least one photovoltaic component 10, and the plurality of isolation channels 102 are arranged in a cross manner. The isolation channel 102 can be used to isolate different sub-photovoltaic areas 101, and on the other hand, a ship can run in the channel to maintain the system. The width and length of the isolation channel 102 can be determined according to the number and size parameters of the ship in the channel, or can be set according to the maintenance or navigation requirements. In the present disclosure, a plurality of sub-photovoltaic areas 101 are arranged in the photovoltaic area 100, and the plurality of sub-photovoltaic areas 101 are separated by the isolation channel 102. Different support structures 11 and photovoltaic components 10 can be installed in batches according to different sea topography, which can improve the installation efficiency of the system and facilitate subsequent batch maintenance. It should be noted that the isolation channel 102 can be located in the sub-photovoltaic area 101, or can be arranged in the sub-photovoltaic area 101. The specific arrangement form of the isolation channel 102 can be adjusted according to the actual requirements of the channel.

[0047] In the embodiments provided in the present disclosure, as shown in Figure 2 As shown, in combination Figure 3 The system includes a plurality of breeding components 20, which are arranged in the breeding area 200. The breeding components 20 are used for fish farming. The photovoltaic area 100 is included in the breeding area 200. The breeding components 20 are located on the side of the second support part 112 away from the photovoltaic panel 12. The breeding components 20 are connected to the photovoltaic components 10. The photovoltaic components 10 provide electric energy for the breeding components 20.

[0048] Since the offshore breeding area 200 generally includes shallow water breeding (water depth within 10m), nearshore breeding (water depth of 10m to 50m), and offshore breeding (water depth above 50m), and the integrated system of offshore photovoltaic and marine ranching is usually arranged in the above-mentioned areas, which forms a contradiction between offshore breeding and offshore photovoltaic. The photovoltaic system has the characteristics of high cleanliness, and the system does not affect or destroy the biological growth environment in the breeding industry. Therefore, in order to improve the utilization rate of offshore space and create an integrated and functional comprehensive system, a comprehensive offshore photovoltaic and offshore breeding system is formed.

[0049] Since there is a preset distance between the second support 112 and the sea level, no other components or structures are installed in this area of ​​the photovoltaic system. Therefore, it is an unused sea area. In order to improve the overall performance of the integrated system of marine photovoltaic and marine ranching and make full use of the sea area, aquaculture components 20 are installed in the aquaculture area 200, and the photovoltaic area 100 is located in the aquaculture area 200. That is to say, the integrated system of marine photovoltaic and marine ranching provided in this disclosure is set in the aquaculture area 200. The photovoltaic system is set up without hindering the fishery aquaculture in the aquaculture area 200, thereby improving the utilization rate of sea space.

[0050] Since the aquaculture component 20 needs to be entirely or partially located in seawater, the aquaculture area 200 is divided into enclosures. The aquaculture component 20 can be located on the side of the second support 112 away from the photovoltaic panel 12. The aquaculture component 20 is connected to the photovoltaic component 10, and the electricity generated by the photovoltaic component 10 can supply the aquaculture component 20 with the required power, saving on land-based power supply procedures and significantly improving the system's self-sufficiency.

[0051] like Figure 3 and Figure 4 As shown, the aquaculture component 20 includes a net component 21 and a fixing component 22. The net component 21 is positioned perpendicular to the sea level, and the enclosed area of ​​the net component 21 at least includes the aquaculture area 200. In some embodiments, the periphery of the aquaculture area 200 may include areas such as aquaculture channels, and the enclosed area of ​​the net component 21 may include the aquaculture channel. Of course, to facilitate navigation in the aquaculture channel, the enclosed area of ​​the net component 21 may only include the aquaculture area 200. The net component 21 can be a net or other mesh structure applicable to aquaculture. The net component 21 can be made of polyethylene netting, etc. The distance of the net component 21 above the sea level needs to be less than or equal to a preset spacing, that is, the distance of the net component 21 above the sea level needs to be less than or equal to 1m, typically 0.4m to 0.5m.

[0052] In some embodiments, the mesh assembly 21 can be directly mounted and fixed around the circumferential position of the first support 111. For example, the mesh assembly 21 can be directly fixed to the pile foundation using fasteners, clamps, or other components. The first support 111 serves as a support structure 11, providing support for the photovoltaic panel 12 and the second support 112, and also provides support and fixation for the mesh assembly 21, thus improving the functionality of the first support 111. Furthermore, the mesh assembly 21 can be mounted on different first support 111s according to the actual needs of the aquaculture area 200, thereby adjusting the mounting area of ​​the mesh assembly 21 and improving the installation flexibility of the mesh assembly 21.

[0053] In some embodiments, the aquaculture assembly 20 can further comprise a fixing assembly 22 for fixing the net assembly 21, the fixing assembly 22 can comprise a frame, an anchor and an accessory, etc., which can provide fixing and support for the net assembly 21, for example, the net assembly 21 can be erected on the frame, the anchor can increase the weight of the net assembly 21, facilitate the stability of the net assembly 21 in water, etc., the fixing assembly 22 in the present disclosure can provide fixing and support for the net assembly 21, facilitate the stability of the net assembly 21 in water. Further, in order to improve the anti-wave capacity of the aquaculture assembly 20, the fixing assembly 22 can be connected with the first support part 111, such as connected by a fastener, a clamping connection, a threaded connection, a welding connection, etc., so that the fixing assembly 22 and the first support part 111 can provide support for each other, improve the stability of the structure.

[0054] In the embodiments provided in the present disclosure, as shown in Figure 1 The aquaculture area 200 can comprise a plurality of first sub-aquaculture areas 201, the first sub-aquaculture areas 201 are arranged one by one with the sub-photovoltaic areas 101, the sub-photovoltaic areas 101 are contained in the first sub-aquaculture areas, and the projections of each isolation channel 102 and the sub-photovoltaic areas 101 on the sea level do not overlap. Wherein, a plurality of support structures 11 are arranged in each sub-photovoltaic area 101, in order to improve the stability of the support structure 11, the adjacent two support structures 11 are connected with each other, for example, the first support part 111 in the adjacent two support structures 11 can be connected with each other through a connecting rod, or connected with each other through a chain; or the second support part 112 in the adjacent two support structures 11 can be connected with each other through a connecting rod, or connected with each other through a chain; or the first support part 111 in the adjacent two support structures 11 can be connected at the same time as the second support part 112 in the adjacent two support structures 11 is connected. The connection mode of the adjacent two support structures 11 includes but is not limited to the above connection mode.

[0055] After the support structures 11 in the same sub-photovoltaic area 101 are connected, they can be regarded as a whole, the isolation channel 102 is arranged outside the sub-photovoltaic area 101, and the isolation channel 102 does not penetrate into the sub-photovoltaic area 101, and the sub-photovoltaic areas 101 are isolated by the isolation channel 102.

[0056] One sub-photovoltaic area 101 corresponds to one first sub-aquaculture area 201, the sub-photovoltaic area 101 is located in the corresponding first sub-aquaculture area 201, or the edge of the sub-photovoltaic area 101 coincides with the edge of the first sub-aquaculture area 201.

[0057] In some embodiments, the net assembly 21 of the farming assembly 20 can be directly fixed on the first support structure 11 at the outermost position of the sub-photovoltaic region 101, or a fixing assembly 22 is arranged on the first support structure 11 at the outermost position of the sub-photovoltaic region 101, and the net assembly 21 is arranged on the fixing assembly 22, so that the sub-photovoltaic region 101 is coincided with the corresponding first sub-farming region 201.

[0058] In some embodiments, the isolation channel 102 at the edge position of the sub-photovoltaic region 101 is included in the net assembly 21 by the fixing assembly 22, so that the sub-photovoltaic region 101 is located inside the corresponding first sub-farming region 201.

[0059] In the above embodiments, the photovoltaic assembly 10 in one sub-photovoltaic region 101 can simultaneously supply power to multiple farming assemblies 20 in the corresponding first sub-farming region 201, such as the feeding tank included in the farming assembly 20 and other components that need to be driven by power.

[0060] In the embodiments provided in the present disclosure, as shown in Figure 2 The farming region 200 can include a plurality of second sub-farming regions 202, and one sub-photovoltaic region 101 includes a plurality of second sub-farming regions 202. A plurality of support structures 11 are arranged in each sub-photovoltaic region 101, and the support structures 11 are arranged in one-to-one correspondence with the second sub-farming regions 202, and the second sub-farming regions are included in the projection of the support structures 11 on the sea level.

[0061] A plurality of support structures 11 are arranged in one sub-photovoltaic region 101, and the second sub-farming regions 202 are in one-to-one correspondence with the support structures 11, that is, the second sub-farming regions are arranged below the second support portions 112. In each sub-photovoltaic region 101, the projection of the second support portion 112 on the sea level covers the projection of the first support portion 111 on the sea level.

[0062] If the first support portion 111 is composed of four pile foundation structures, and the four piles are respectively used to support the positions of the four corners of the second support portion 112, that is, the distances from the four pile foundation structures to the center of gravity of the second support portion 112 are the same, then the projection of the first support portion 111 on the sea level is included in the projection of the second support portion 112 on the sea level. If the four piles in the first support portion 111 are arranged exactly at the positions of the four corners of the second support portion 112, then the projection of the first support portion 111 on the sea level is coincided with the projection of the second support portion 112 on the sea level. It should be noted that, since the support structures 11 are in one-to-one correspondence with the second sub-farming regions, and the isolation channel 102 is used to separate the sub-photovoltaic regions 101, the second sub-farming regions do not include the isolation channel 102.

[0063] In some embodiments, the second sub-culture area is overlapped with the projection of the first support part 111 on the sea level, i.e. by directly fixing the net assembly 21 in the second sub-culture area on the first support part 111, or directly fixing the fixing assembly 22 in the second sub-culture area on the pile foundation of the first support part 111.

[0064] In some embodiments, the second sub-culture area covers the projection of the first support part 111 on the sea level, i.e. by arranging the fixing assembly 22 between the edge of the first support part 111 and the edge of the second support part 112, and then arranging the net assembly 21 on the fixing assembly 22.

[0065] In the above embodiments, the photovoltaic assembly 10 arranged on the support structure 11 can only supply power to the culture assembly 20 in the corresponding second sub-culture area 202, and the power generated by the photovoltaic assembly 10 can be used for the power-driven components included in the culture assembly 20, such as the feeding tank.

[0066] The second sub-culture area provided in the above embodiments can classify the culture species according to the characteristics of the sea area, and different marine organisms can be cultured in different second sub-culture areas, or marine species with correlation can be cultured in adjacent two second sub-culture areas 202, so as to improve the survival rate and culture efficiency of the organisms and facilitate centralized management.
