[0028] Example

[0029] This embodiment is suitable for offshore environments where the wave frequency and amplitude are high.

[0030] See also Figure 1 This embodiment provides a floating box photovoltaic system. Specifically, the floating box photovoltaic system includes a floating box photovoltaic device 100, a mooring device 200 and an anchoring device 300.

[0031] See also Figure 1 , Figure 2 and Figure 3 , a plurality of floating box type photovoltaic devices 100 are linearly arranged along a first direction, and adjacent floating box type photovoltaic devices 100 are hinged or elastically connected to each other.

[0032] The first direction here refers to the impact direction of the waves. In this embodiment, two floating photovoltaic devices 100 are used for exemplary description, and a floating photovoltaic device 100 close to the waves is defined as a first floating photovoltaic device 101, and a floating photovoltaic device 100 far from the waves is defined as a second floating photovoltaic device 102.

[0033] In some embodiments, adjacent floating box photovoltaic devices 100 are hinged to each other, and the hinged connection method is specifically as follows: the floating box photovoltaic device 100 further includes a hinge 103, and adjacent floating box photovoltaic devices 100 are connected by the hinge 103. Under the impact of waves, adjacent floating box photovoltaic devices 100 can rotate relative to each other and rise and fall with the waves, thereby reducing the impact of waves and improving the stability and reliability of the floating box photovoltaic system.

[0034] Furthermore, the floating photovoltaic device 100 further includes a fastener 104 , and the fastener 104 connects the hinge 103 and the floating photovoltaic device 100 respectively.

[0035] In some embodiments, adjacent floating photovoltaic devices 100 are elastically connected to each other, and the elastic connection method is specifically: the floating photovoltaic device 100 also includes a connector, and the adjacent floating photovoltaic devices 100 are connected through the connector, and the connector is made of elastic materials such as polyurethane.

[0036] In summary, each floating box photovoltaic device 100 is connected in a hinged or elastic manner, which can effectively offset the impact force brought by the waves and reduce the risk of the floating box tipping.

[0037] See also Figures 2 to 4 Each floating box-type photovoltaic device 100 includes a frame structure 110 and a photovoltaic panel 120. The frame structure 110 includes a first floating member 111, a second floating member 112, a third floating member 113 and a fourth floating member 114. The first floating member 111, the second floating member 112, the third floating member 113 and the fourth floating member 114 are enclosed to form a receiving cavity, and the photovoltaic panel 120 is located in the receiving cavity.

[0038] The first floating member 111 and the second floating member 112 are arranged parallel to each other, the third floating member 113 is vertically adjacent to the first floating member 111 and the second floating member 112 respectively, and the fourth floating member 114 is vertically adjacent to the first floating member 111 and the second floating member 112 respectively.

[0039] When the floating photovoltaic system floats on the sea, the third floating member 113 of the first floating photovoltaic device 101 faces the waves, and the fourth floating member 114 of the first floating photovoltaic device 101 and the third floating member 113 of the second floating photovoltaic device 102 are hinged or elastically connected to each other.

[0040] In some embodiments, the frame structure 110 further includes a fixing member 115 , and the number of the fixing member 115 is plural.

[0041] An exemplary description is given assuming that each frame structure 110 includes four fixing members 115 .

[0042] The first solution is: two fixing members 115 are fixedly connected to the third floating member 113 , and the other two fixing members 115 are fixedly connected to the fourth floating member 114 .

[0043] The second solution is: two fixing members 115 are fixedly connected to the first floating member 111 , and the other two fixing members 115 are fixedly connected to the second floating member 112 .

[0044] For example, each frame includes eight fixing members 115 : two fixing members 115 are fixedly connected to the first floating member 111 , two fixing members 115 are fixedly connected to the second floating member 112 , two fixing members 115 are fixedly connected to the third floating member 113 , and another two fixing members 115 are fixedly connected to the fourth floating member 114 .

[0045] It is understandable that the solution of providing the fixing member 115 on the first floating member 111, the second floating member 112, the third floating member 113 and the fourth floating member 114 has a better fixing ability, ensuring that the photovoltaic panel 120 will not be detached under the impact of waves.

[0046] This embodiment can also be set as follows: at least a portion of each fixing member 115 is located in the accommodating cavity, the frame structure 110 is provided with an extension portion 116, the extension portion 116 is located at the bottom of the frame structure 110, and the extension portion 116 extends from the cavity wall of the accommodating cavity toward the accommodating cavity, and the extension portion 116 and the fixing member 115 jointly clamp the photovoltaic panel 120.

[0047] Specifically, one end of the fixing member 115 is fixedly connected to the frame structure 110 , and the other end extends out and is located in the accommodating cavity. The extension portion 116 and the fixing member 115 are arranged opposite to each other to form a space for accommodating the photovoltaic panel 120 .

[0048] This embodiment can fix the photovoltaic panel 120 by clamping, without adding other additional fixing elements, thus simplifying the structure and reducing the preparation cost.

[0049] During installation, the photovoltaic panel 120 is first placed in the accommodation space with the lower surface of the photovoltaic panel 120 abutting against the extension portion 116 . Then, one end of the fixing member 115 is fixed to the frame structure 110 , and the other end of the fixing member 115 presses the photovoltaic panel 120 .

[0050] In some embodiments, the fixing member 115 is also fixedly connected to the photovoltaic panel 120. On the basis that one end of the fixing member 115 is fixed to the frame structure 110, the other end of the fixing member 115 is fixed to the photovoltaic panel 120, that is, the fixing member 115 is respectively fixedly connected to the frame structure 110 and the photovoltaic panel 120. This installation method is more stable and less likely to get loose.

[0051] In some embodiments, the first float 111, the second float 112, the third float 113 and the fourth float 114 are integrally formed, and the first float 111, the second float 112, the third float 113 and the fourth float 114 each include a protective layer and a filling layer, the protective layer is provided with a filling space, and the filling layer is located in the filling space.

[0052] In actual use, the protective layer is made of metal material and the filling layer is made of foam material. The function of the foam material is to improve the buoyancy of the frame structure 110. The metal material is coated on the outside of the filling layer, which can protect the filling layer and prevent the filling layer from being damaged by the corrosion of seawater, thereby extending the service life of this embodiment.

[0053] In actual use, the floating box photovoltaic device 100 has a rectangular box structure. It can be understood that the floating box photovoltaic device 100 has a lower height and is not easily affected by the impact of waves, which reduces torque and improves the stability of the floating box photovoltaic system.

[0054] In addition, the present embodiment can also set the floating box photovoltaic device 100 to have a chamfer 117. The setting of the chamfer 117 has two advantages. One is to prevent the installers from being cut by sharp corners during installation, and the other is to reduce the collision of adjacent floating box photovoltaic devices 100 during the floating process.

[0055] Please continue reading Figure 1 The mooring device 200 is respectively connected to the anchoring device 300 and at least one floating photovoltaic device 100. In this embodiment, the mooring device 200 can be set as a tool such as a cable, and one end of the mooring device 200 is fixedly connected to the second floating photovoltaic device 102, and the other end of the mooring device 200 is fixedly connected to the anchoring device 300.

[0056] The floating box photovoltaic device 100 of the present application is fixed on the anchor device 300 through the mooring device 200, which greatly improves the stability and reliability of the floating box photovoltaic system. The anchor device 300 is anchored on land to provide support for the floating box photovoltaic device 100.
