[0032] Example

[0033] This embodiment is applicable to the improved use of raft aquaculture facilities and provides feasible space for improving economic benefits based on the existing raft aquaculture facilities.

[0034] See also Figures 1 to 3 This embodiment provides a floating photovoltaic power generation system. Specifically, the floating photovoltaic power generation system includes a cage assembly (not shown in the figure), a raft assembly 100, an elevated assembly 200 and a photovoltaic assembly 300.

[0035] The cage assembly includes multiple cages, each of which is used for aquaculture. The aquaculture objects such as shellfish or algae are placed in the cages, and then the cages are placed in seawater for aquaculture. The cages are often used for seawater aquaculture, which is convenient for aquaculture personnel to carry out rotational catching and releasing. During the breeding process, fish that meet the market specifications are caught in stages and batches, and fish fingerlings are added in appropriate amounts to fully utilize the aquaculture water to increase production.

[0036] The floating raft assembly 100 includes a transverse support member 110, a longitudinal support member 120 and a floating member 130, wherein the transverse support member 110 and the longitudinal support member 120 constitute a raft frame, and the floating member 130 is arranged on the raft frame to make the raft frame float.

[0037] In this embodiment, a plurality of transverse support members 110 may be arranged at intervals along a first direction, and the transverse support member 110 may be provided with a first surface 111 and a second surface 112, the first surface 111 and the second surface 112 being arranged opposite to each other, wherein the first surface 111 is the upper surface of the transverse support member 110, and the second surface 112 is the lower surface of the transverse support member 110.

[0038] Multiple longitudinal support members 120 are arranged at intervals along a second direction perpendicular to the first direction, and each longitudinal support member 120 is fixedly connected to at least two transverse support members 110 and defines an avoidance area. Through the supporting effect of at least two transverse support members 110, the longitudinal support members 120 have a better placement state.

[0039] The avoidance area here is exposed on the surface of the water body to facilitate aquaculture operations. In this embodiment, the avoidance area refers to the position range surrounded by the longitudinal support member 120 and the transverse support member 110, for example: a field-shaped avoidance area.

[0040] In some embodiments, one longitudinal support member 120 is fixedly connected to two transverse support members 110 .

[0041] In some embodiments, one longitudinal support member 120 is fixedly connected to three transverse support members 110 .

[0042] It is understandable that there is no restriction on the number of longitudinal support members 120 and transverse support members 110, and the assembly method of the longitudinal support member 120 and a plurality of transverse support members 110 fixedly connected depends not only on the length of the longitudinal support member 120, but also on the distance between the first transverse support member 110 and the last transverse support member 110. According to the length of the longitudinal support member 120 and the distance between the transverse support members 110, an adaptive number setting can be obtained.

[0043] In actual use, the transverse support member 110 and the longitudinal support member 120 are configured as wooden blocks.

[0044] A plurality of floating members 130 are installed on the transverse supporting member 110 and / or the longitudinal supporting member 120, and there are three cases. The first case is that all the floating members 130 are installed on the transverse supporting member 110. The second case is that all the floating members 130 are installed on the longitudinal supporting member 120. The third case is that some of the floating members 130 are installed on the transverse supporting member 110, and some of the floating members 130 are installed on the longitudinal supporting member 120.

[0045] In the third case, this embodiment can also configure the number of floating members 130 in a reasonable manner, so that the floating members 130 are arranged in a regular array on the raft frame, ensuring uniform buoyancy at various positions of the floating photovoltaic power generation system and improving the safety of aquaculture.

[0046] A plurality of cages are installed on the transverse support member 110 and / or the longitudinal support member 120. Similar to the floating member 130, there are three cases, the first case is that all the cages are installed on the transverse support member 110. The second case is that all the cages are installed on the longitudinal support member 120. The third case is that some cages are installed on the transverse support member 110 and some cages are installed on the longitudinal support member 120.

[0047] Similarly, in the third case, the present embodiment can also configure the number of cages in a reasonable manner, so that the cages are arranged in a regular array on the raft frame, thereby optimizing the breeding environment of the floating photovoltaic power generation system.

[0048] In some embodiments, the longitudinal support member 120 is disposed on the first surface 111 , that is, the longitudinal support member 120 is located above the transverse support member 110 . Specifically, the longitudinal support member 120 is provided with a mounting surface, which abuts against the first surface 111 . The mounting surface here is the lower surface of the longitudinal support member 120 .

[0049] When the floating member 130 is arranged in the third case, that is, part of the floating member 130 is installed on the transverse support member 110, and part of the floating member 130 is installed on the longitudinal support member 120, at this time, at least part of the floating member 130 is arranged on the second surface 112, and at least part of the floating member 130 is arranged on the installation surface.

[0050] In some embodiments, the longitudinal support member 120 is disposed on the second surface 112 , that is, the transverse support member 110 is located above the longitudinal support member 120 .

[0051] It can be understood that the solution of disposing all the longitudinal support members 120 on the transverse support members 110 or all the transverse support members 110 on the longitudinal support members 120 can improve the integrity and stability of the floating photovoltaic power generation system. Of course, it is also possible to adopt a solution of disposing some of the longitudinal support members 120 on the transverse support members 110 and some of the transverse support members 110 on the longitudinal support members 120, which is not limited here.

[0052] When the floating member 130 is arranged in the third case, that is, part of the floating member 130 is installed on the transverse support member 110, and part of the floating member 130 is installed on the longitudinal support member 120, at this time, in order to achieve the fixation of the floating member 130, the raft assembly 100 also includes a tightening member 140, at least part of the tightening member 140 is wrapped around the floating member 130 and the transverse support member 110, and at least part of the tightening member 140 is wrapped around the floating member 130 and the longitudinal support member 120.

[0053] The number of elevated components 200 is multiple groups. In this embodiment, it can be set that the spacing between two adjacent groups of elevated components 200 is equal. In this way, the weight distribution of each position of the floating photovoltaic power generation system is more uniform, and even under the influence of sea breeze, the elevated components 200 will not fall over.

[0054] In some embodiments, each longitudinal support member 120 is respectively equipped with a group of elevated components 200 , and the spacing between adjacent groups of elevated components 200 is equal to the spacing between adjacent longitudinal support members 120 .

[0055] In some embodiments, at least a portion of the longitudinal support members 120 is equipped with a group of elevated components 200 , for example, adjacent groups of elevated components 200 are arranged with one longitudinal support member 120 between them.

[0056] Each set of elevated components 200 includes a plurality of first elevated members 210 and a second elevated member 220. The plurality of first elevated members 210 are arranged on the longitudinal support member 120 at intervals along the first direction. Each second elevated member 220 is respectively mounted on at least two first elevated members 210. It can be understood that the second elevated members 220 are extended along the first direction.

[0057] Each set of elevated components 200 further includes a plurality of gaskets 230, and each first elevated member 210 is fixed to the longitudinal support member 120 via a gasket 230. The cross-sectional area of ​​the gasket 230 is greater than the cross-sectional area of ​​the first elevated member 210. In this embodiment, the gasket 230 is provided to expand the force bearing area of ​​the first elevated member 210 and reduce the risk of the first elevated member 210 tilting.

[0058] This embodiment is suitable for water environments such as tidal flats. Since the sea surface of the tidal flats is relatively calm, the use of the elevated component 200 will not cause the floating photovoltaic power generation system to topple over, thereby ensuring the stability and reliability of the floating photovoltaic power generation system.

[0059] The photovoltaic module 300 is laid on the elevated module 200, and a pedestrian passage 400 is formed between the photovoltaic module 300 and the floating raft module 100. The height of the pedestrian passage 400 is between 1.8 meters and 3 meters. Firstly, the height of 1.8 meters meets the passage requirements of most aquaculture personnel, reduces the bending of aquaculture personnel, and improves the comfort of aquaculture. Secondly, the height of 3 meters can reduce the risk of the floating photovoltaic power generation system being overturned by the sea breeze.

[0060] Therefore, the height setting of the pedestrian passage 400 in this embodiment can improve the good breeding environment as much as possible and enhance the user experience of the breeding personnel while ensuring the stability of the floating photovoltaic power generation system.

[0061] Please refer to Figure 1 and Figure 4The photovoltaic assembly 300 includes a purlin 310 and a photovoltaic panel 320. A plurality of purlins 310 are arranged on the second elevated member 220 at intervals along the first direction, and the photovoltaic panel 320 is laid on at least two purlins 310. A plurality of photovoltaic panels 320 are laid on every two purlins 310, and the plurality of photovoltaic panels 320 are arranged at intervals along the second direction.

[0062] In this embodiment, in the first direction, the photovoltaic panels 320 are arranged at a preset distance. Therefore, there is a gap between two adjacent photovoltaic panels 320 in the first direction, so that sunlight can shine on the cage to meet the normal growth needs of the breeding objects.

[0063] This embodiment utilizes the existing raft-type aquaculture facilities, adds the elevated components 200 and the photovoltaic components 300, realizes the function of solar power generation, improves the economic benefits of the floating photovoltaic power generation system, and under the shielding of the photovoltaic panel 320, can effectively inhibit the growth of alien plants such as Spartina alterniflora, making the water environment around the cage more conducive to the cultivation of aquaculture objects.
