[0002] Offshore photovoltaic systems are gradually moving into deeper waters, providing a development platform for floating photovoltaic systems. Conventional floating foundations use mooring systems, which are costly to build. The anchor chains of mooring systems are long, making installation complex and maintenance costly. Moreover, floating photovoltaic systems occupy a large sea area and are difficult to adjust. Summary of the Invention

[0003] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention propose a floating photovoltaic system for marine applications, which has the advantages of simple installation, easy adjustment, and low cost.

The second float is connected to the first float and is movable relative to the first float in a first direction. The second float has a first position and a second position. When the second float is in the first position, the second float and the first float are stacked. When the second float is in the second position, the second float and the first float are unfolded.

[0007] The photovoltaic module is provided on the top surface of both the first floating plate and the second floating plate, and the photovoltaic module is movable relative to both the first floating plate and the second floating plate.

[0008] The floating photovoltaic system of this invention features a positioning component that simplifies the positioning of the floating components. Compared to existing mooring systems, this prevents the floating components from being easily carried away by external forces, ensuring their stability and reducing maintenance costs. Furthermore, adjacent floats can be deployed or stacked, making it easy to adjust the sea area occupied by the floating components. The photovoltaic components can be movably installed on the floats, facilitating adjustments to their arrangement.

[0010] In some embodiments, the top surface of the first floating plate and the top surface of the second floating plate are both provided with a first slide rail. The first slide rail extends along the first direction. The photovoltaic module is slidably installed in the first slide rail.

The photovoltaic module can be moved from the second floating plate to the first floating plate or from the first floating plate to the second floating plate.

[0011] In some embodiments, there are multiple first slides on the first float and multiple first slides on the second float. The multiple first slides on the first float and multiple first slides on the second float are arranged at intervals along a second direction, which is orthogonal to the first direction. When the second float and the first float are deployed, the multiple first slides on the second float and the multiple first slides on the first float correspond one-to-one and are connected.

[0012] In some embodiments, the top surfaces of the first floating plate and the second floating plate are each provided with a second slide rail.

The central axis of the second slide rail and the central axis of the first slide rail are located on the same plane, and the photovoltaic module can be moved from the first slide rail to the second slide rail.

[0013] In some embodiments, the floating assembly further includes a float ball, which is provided on the bottom surface of both the first float plate and the second float plate.

[0017] In some embodiments, the first float includes a first bottom plate, a first side plate, and a first connecting plate. There are two first side plates, which are arranged at intervals along a second direction on the top surface of the first bottom plate. The first side plates extend along the first direction, which is orthogonal to the second direction. The first connecting plate is disposed at one end of the first side plate adjacent to the positioning member and is used to connect the two first side plates. The first slide rail is provided on the top surface of the first bottom plate and the inner wall surface of the first side plate.

[0018] In some embodiments, the second float includes a second bottom plate, a second side plate, and a second connecting plate.

[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] like Figures 1-10 As shown, the floating photovoltaic system of this invention includes a positioning component 1, a floating assembly 2, and a photovoltaic module 3. One end of the positioning component 1 (e.g., Figure 1 The lower end of the positioning element 1 shown is fixed to the seabed, and the other end of the positioning element 1 (such as...) Figure 1 The upper end of the positioning component 1 shown extends out of the sea surface.

[0033] The floating assembly 2 includes a first float 21 and a second float 22. One end of the first float 21 is connected to the other end of the positioning member 1. The second float 22 is connected to the first float 21 and is movable relative to the first float 21 in a first direction. The second float 22 has a first position and a second position. When the second float 22 is in the first position, the second float 22 and the first float 21 are stacked. Specifically, when the second float 22 and the first float 21 are stacked, at least a portion of the second float 22 is located within the first float 21. When the second float 22 is in the second position, the second float 22 and the first float 21 are unfolded. Specifically, the top surface of the second float 22 is substantially flush with the top surface of the first float 21, and the bottom surface of the second float 22 is substantially flush with the bottom surface of the first float 21. Photovoltaic modules 3 are provided on the top surfaces of both the first float 21 and the second float 22. The photovoltaic modules 3 are movable relative to both the first float 21 and the second float 22.

[0034] The floating photovoltaic system of this invention features a positioning component 1, which simplifies the positioning of the floating component 2. Compared to existing mooring systems, this prevents the floating component 2 from being easily carried away by external forces, ensuring its stability and reducing maintenance costs. Furthermore, adjacent floating plates can be deployed or stacked, making it easy to adjust the sea area occupied by the floating component 2. The photovoltaic component 3 is movably installed on the floating plate, making it easy to adjust the arrangement of the photovoltaic component 3.

[0035] In some embodiments, the floating assembly 2 further includes a third float 23. The first float 21, the third float 23, and the second float 22 are arranged sequentially along a first direction. The third float 23 is connected to the first float 21 and can move relative to the first float 21 along the first direction. The second float 22 is connected to the third float 23 and can move relative to the third float 23 along the first direction. When the second float 22 is in the first position, the second float 22, the third float 23, and the first float 21 are stacked sequentially. When the second float 22 is in the second position, the second float 22, the third float 23, and the first float 21 are unfolded sequentially.

[0036] Specifically, the floating assembly 2 also includes a fourth float 24, which has the same structure as the third float 23. The first float 21, third float 23, fourth float 24, and second float 22 are arranged sequentially along a first direction. When the second float 22 is in the first position, the second float 22, fourth float 24, third float 23, and first float 21 are stacked sequentially. When the second float 22 is in the second position, the second float 22, fourth float 24, third float 23, and first float 21 are deployed sequentially. The floating assembly 2 can adjust its sea area according to actual conditions to improve safety and stability, and increase the working efficiency of the photovoltaic module 3.

[0037] In some embodiments, the top surface of the first floating plate 21 and the top surface of the second floating plate 22 are both provided with a first slide rail 41. The first slide rail 41 extends along a first direction. The photovoltaic module 3 is slidably installed in the first slide rail 41. When the second floating plate 22 and the first floating plate 21 are unfolded, the first slide rail 41 on the second floating plate 22 corresponds to and is connected to the first slide rail 41 on the first floating plate 21. The photovoltaic module 3 can be moved from the second floating plate 22 to the first floating plate 21 or from the first floating plate 21 to the second floating plate 22.

[0038] Specifically, the second float plate 22 is slidably mounted on the first slide rail 41 on the first float plate 21, so that the second float plate 22 can move relative to the first float plate 21 along the first slide rail 41 on the first float plate 21. The photovoltaic module 3 on the first float plate 21 can also move along the first slide rail 41 on the first float plate 21, and the photovoltaic module 3 on the second float plate 22 can move along the first slide rail 41 on the second float plate 22.

[0039] When the second floating plate 22 and the first floating plate 21 are deployed, the top surface of the second floating plate 22 is roughly flush with the top surface of the first floating plate 21, so that the first slide rail 41 on the first floating plate 21 and the first slide rail 41 on the second floating plate 22 can be roughly flush, so as to facilitate the movement of the photovoltaic module 3 on the first floating plate 21 and the first floating plate 22. When the second floating plate 22 is stacked with the first floating plate 21, the photovoltaic module 3 on the first floating plate 21 is first moved to the second floating plate 22 through the first slide rail 41, and then the second floating plate 22 is slid along the first slide rail 41 on the first floating plate 21 to the first floating plate 21 to be stacked with the first floating plate 21.

[0040] In some embodiments, there are multiple first slide rails 41 on the first float plate 21 and multiple first slide rails 41 on the second float plate 22. The multiple first slide rails 41 on the first float plate 21 and multiple first slide rails 41 on the second float plate 22 are arranged at intervals along a second direction, which is orthogonal to the first direction. When the second float plate 22 and the first float plate 21 are deployed, the multiple first slide rails 41 on the second float plate 22 and the multiple first slide rails 41 on the first float plate 21 correspond one-to-one and are connected.

[0041] Specifically, multiple first slide rails 41 are provided on the top surface of the first float plate 21 and the top surface of the second float plate 22, making the second float plate 22 more stable when moving on the first float plate 21.

[0042] In some embodiments, the top surface of the first floating plate 21 and the top surface of the second floating plate 22 are both provided with a second slide rail 42. The second slide rail 42 extends along a second direction and is connected to the first slide rail 41. The central axis of the second slide rail 42 and the central axis of the first slide rail 41 are located on the same plane, and the photovoltaic module 3 can be moved from the first slide rail 41 to the second slide rail 42.

[0043] Specifically, the second slide rail 42 on the first floating plate 21 extends along the second direction. There are multiple second slide rails 42 on the first floating plate 21. The multiple second slide rails 42 are arranged at intervals along the first direction and are connected to multiple first slide rails 41 on the first floating plate 21, so that the photovoltaic module 3 on the first floating plate 21 can be moved to different first slide rails 41 through the second slide rails 42.

[0044] The second slide rail 42 on the second floating plate 22 extends along the second direction. There are multiple second slide rails 42 on the second floating plate 22, which are arranged at intervals along the first direction and communicate with multiple first slide rails 41 on the second floating plate 22. This allows the photovoltaic module 3 on the second floating plate 22 to be moved to different first slide rails 41 via the second slide rails 42. When the second floating plate 22 is stacked with the first floating plate 21, it is less likely for the photovoltaic module 3 on the first floating plate 21 to collide with the photovoltaic module 3 on the second floating plate 22 when it is moved to the second floating plate 22.

[0045] In some embodiments, the top surface of the third float plate 23 is also provided with a first slide rail 41 and a second slide rail 42, and the top surface of the fourth float plate 24 is also provided with a first slide rail 41 and a second slide rail 42.

[0046] In some embodiments, the floating assembly 2 further includes a float 5. The bottom surface of the first float 21 and the bottom surface of the second float 22 are both provided with floats 5. The floats 5 can move relative to the first float 21 and the second float 22. When the second float 22 and the first float 21 are deployed, the bottom surface of the second float 22 and the bottom surface of the second float 22 are approximately flush. The floats 5 can move from the second float 22 to the first float 21 or from the first float 21 to the second float 22.

[0047] Specifically, both the bottom surface of the first float plate 21 and the bottom surface of the second float plate 22 are provided with third slide rails 43, which extend along a first direction. The first float plate 21 has multiple third slide rails 43, which are spaced apart along a second direction. The second float plate 22 also has multiple third slide rails 43, which are spaced apart along the second direction. The float ball 5 is slidably installed within the third slide rails 43. When the second float plate 22 and the first float plate 21 are deployed, the multiple third slide rails 43 on the second float plate 22 correspond one-to-one with and are connected to the multiple third slide rails 43 on the first float plate 21, allowing the float ball 5 to move on both the second float plate 22 and the first float plate 21.

[0048] Specifically, the bottom surfaces of the first float plate 21 and the second float plate 22 are both provided with a fourth slide rail 44. The fourth slide rail 44 extends along the second direction and is connected to a third slide rail 43. The central axis of the fourth slide rail 44 and the central axis of the third slide rail 43 are located on the same plane, so that the float 5 can move through the fourth slide rail 44 to different third slide rails 43. When the second float plate 22 and the first float plate 21 are stacked, the float 5 on the second float plate 22 is first moved to the bottom surface of the first float plate 21 through the third slide rail 43, and then the second float plate 22 is slid along the first slide rail 41 on the first float plate 21 to be stacked with the first float plate 21.

[0049] In some embodiments, the bottom surface of the third float plate 23 is also provided with a third slide rail 43 and a fourth slide rail 44, and the bottom surface of the fourth float plate 24 is also provided with a third slide rail 43 and a fourth slide rail 44.

[0050] In some embodiments, the photovoltaic module 3 includes a first support 31, a second support 32, and a photovoltaic panel 33. The first support 31 and the second support 32 are arranged at intervals along a second direction, and one end of the first support 31 (e.g., Figure 3 The lower end of the first bracket 31 shown is slidably installed in one of the first slide rails 41, and the other end of the first bracket 31 (as shown) Figure 3 The upper end of the first bracket 31 shown extends upwards. One end of the second bracket 32 ​​(as shown) Figure 3 The lower end of the second bracket 32 ​​shown is slidably mounted in another first slide rail 41, and the other end of the second bracket 32 ​​(as shown) Figure 3 The upper end of the second bracket 32 ​​shown extends upward, and one end of the first bracket 31 and one end of the second bracket 32 ​​can both slide into other first slide rails 41 via the second slide rail 42. The photovoltaic panel 33 has a track 331 that extends along a second direction, and the other end of the first bracket 31 and the other end of the second bracket 32 ​​are slidably installed in the track 331.

[0051] Specifically, there are two tracks 331, which are spaced apart and arranged opposite each other along a first direction. The first bracket 31 and the second bracket 32 ​​are spaced apart and arranged opposite each other along a second direction. The upper end of the first bracket 31 is slidably mounted in the two tracks 331, and the upper end of the second bracket 32 ​​is also slidably mounted in the two tracks 331, so that the upper ends of the first bracket 31 and the upper ends of the second bracket 32 ​​can move relative to the photovoltaic panel 33 along the second direction. This allows the photovoltaic panel 33 to move within different first slide rails 41 via the first bracket 31 and the second bracket 32, and the adjustment method is simple.

[0052] In some embodiments, the first float plate 21 includes a first bottom plate 211, a first side plate 212, and a first connecting plate 213. There are two first side plates 212, which are arranged at intervals along a second direction on the top surface of the first bottom plate 211. The first side plates 212 extend along a first direction. The first connecting plate 213 is provided at one end of the first side plate 212 adjacent to the positioning member 1 and is used to connect the two first side plates 212. The top surface of the first bottom plate 211 and the inner wall surface of the first side plate 212 are both provided with first slide rails 41.

[0053] Specifically, the first floating plate 21 has a simple structure, is easy to manufacture, and saves costs.

[0054] In some embodiments, the second float 22 includes a second bottom plate 221, a second side plate 222, and a second connecting plate (not shown). There are two second side plates 222, spaced apart along a second direction on the top surface of the second bottom plate 221. The second side plates 222 extend along a first direction. The second connecting plate is located at the end of the second side plate 222 away from the positioning member 1 and is used to connect the two second side plates 222. A first slide rail 41 is provided on the top surface of the second bottom plate 221 and the inner wall surface of the second side plate 222. A slider 6 is provided on the bottom surface of the second bottom plate 221 and the outer wall surface of the second side plate 222. The slider 6 is slidably mounted within the first slide rail 41 on the first float 21.

[0055] Specifically, the connection between the second float plate 22 and the first float plate 21 is simple and easy to operate. Moreover, the second float plate 22 has a simple structure, is easy to manufacture, and saves costs.

[0056] In some embodiments, the third float 23 includes a third bottom plate 231 and a third side plate 232. There are two third side plates 232, which are spaced apart along a second direction on the top surface of the third bottom plate 231 and extend along a first direction. A first slide rail 41 is provided on the top surface of the third bottom plate 231 and the inner wall surface of the third side plate 232. A slider 6 is provided on the bottom surface of the third bottom plate 231 and the outer wall surface of the third side plate 232. The slider 6 is slidably mounted within the first slide rail 41 on the first float 21, and the slider 6 on the second float 22 is slidably mounted within the first slide rail 41 on the third float 23.

[0057] In some embodiments, the end of the first base plate 211 away from the positioning member 1 is provided with a notch 71, and the end of the second base plate 221 adjacent to the positioning member 1 is provided with a protrusion 72. The protrusion 72 and the notch 71 are adapted to each other. When the second float plate 22 moves from the first position to the second position, the protrusion 72 engages with the notch 71.

[0058] Specifically, as the second float 22 unfolds with the first float 21, and the second float 22 moves from the first position to the second position along the first slide rail 41 on the first float 21, when the end of the second base plate 221 adjacent to the positioning member 1 moves to the end of the first base plate 211 away from the positioning member 1, the protrusion 72 on the second base plate 221 corresponds to the recess 71 on the first base plate 211, and the second base plate 221 is pressed down so that the protrusion 72 on the second base plate 221 is fitted and installed on the first... The protrusion 72 is not easily dislodged from the recess 71 on the base plate 211. The top surface of the second base plate 221 is roughly flush with the top surface of the first base plate 211. The first slide rail 41 on the first base plate 211 and the first slide rail 41 on the second base plate 221 correspond one-to-one and are connected. The bottom surface of the second base plate 221 is roughly flush with the bottom surface of the first base plate 211. The third slide rail 43 on the second base plate 221 and the third slide rail 43 on the first base plate 211 correspond one-to-one and are connected.

[0059] When the second floating plate 22 is stacked with the first floating plate 21, the photovoltaic module 3 on the first floating plate 21 is first slid onto the second bottom plate 221 through the first slide rail 41 connecting the first bottom plate 211 and the second bottom plate 221, so that multiple photovoltaic modules 3 can be stacked to save space. The float ball 5 on the second floating plate 22 is slid onto the first bottom plate 211 through the third slide rail 43 connecting the first bottom plate 211 and the second bottom plate 221. Then the second bottom plate 221 is lifted up, so that the protrusion 72 on the second bottom plate 221 disengages from the recess 71 on the first bottom plate 211. The slider 6 on the second bottom plate 221 enters the first slide rail 41 on the first bottom plate 211, so that the second bottom plate 221 can slide along the first slide rail 41 on the first bottom plate 211.
