[0025] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0026] like Figure 1-6 As shown, the offshore photovoltaic device of the embodiment of the present invention comprises a guide rail 1, a photovoltaic panel 2 and a protective assembly 3. The guide rail 1 extends in the up-down direction, the lower end of the guide rail 1 is arranged on the seabed 71, and the upper end of the guide rail 1 extends out of the sea surface 72. The photovoltaic panel 2 is arranged on the guide rail 1 and can move in the up-down direction relative to the guide rail 1.

[0027] Specifically, a pile foundation 4 is provided on the seabed 71, and the pile foundation 4 extends in the up-down direction, the lower end of the pile foundation 4 is provided on the seabed 71, and the upper end of the pile foundation 4 extends out of the sea surface 72, and the guide rail 1 is provided on the pile foundation 4. There are two pile foundations 4, and the two pile foundations 4 are arranged at intervals along the first direction, there are two guide rails 1, and the two guide rails 1 correspond to the two pile foundations 4 one by one, and the photovoltaic panel 2 is provided between the two guide rails 1.

[0028] The protection assembly 3 includes a mounting frame 31 and a protection cloth 32. The mounting frame 31 has a mounting groove 311. The mounting groove 311 penetrates the mounting frame 31 along the thickness direction of the mounting frame 31. The photovoltaic panel 2 is arranged in the mounting groove 311. The protection cloth 32 is arranged on one side of the mounting frame 31. The protection cloth 32 can move relative to the mounting frame 31 toward the other side opposite to the one side of the mounting frame 31 to cover the photovoltaic panel 2. Specifically, one side of the mounting frame 31 and the other side of the mounting frame 31 both extend along the first direction, and the protection cloth 32 also extends along the first direction.

[0029] The offshore photovoltaic device of the embodiment of the present invention seals the photovoltaic panel 2 in the installation frame 31 through the protective cloth 32. The photovoltaic panel 2 moves along the guide rail 1 to below the sea surface 72, thereby reducing the impact of typhoons on the photovoltaic panel 2, preventing the typhoon from damaging the photovoltaic panel 2, and ensuring the service life of the photovoltaic panel 2.

[0030] In some embodiments, the protective cloth 32 is made of waterproof material to ensure that when the photovoltaic panel 2 moves below the sea surface 72 , the seawater is not likely to soak the protective cloth 32 and affect the photovoltaic panel 2 .

[0031] In some embodiments, the photovoltaic panel 2 can rotate about a first direction relative to the guide rail 1, and the first direction is orthogonal to the up and down directions, so that the inclination angle of the photovoltaic panel 2 can be adjusted, so that the photovoltaic panel 2 can better absorb sunlight and ensure the working efficiency of the photovoltaic panel 2. Moreover, when the photovoltaic panel 2 moves below the sea surface 72, the inclination angle of the photovoltaic panel 2 can be adjusted to reduce the impact of seawater on the photovoltaic panel 2 and ensure the service life of the photovoltaic panel 2.

[0032] In some embodiments, the offshore photovoltaic device further includes a first rotating shaft 51 and a second rotating shaft 52. The first rotating shaft 51 is disposed on one side of the installation frame 31 and extends along the first direction, and the second rotating shaft 52 is disposed on the other side of the installation frame 31 and extends along the first direction, and the first rotating shaft 51 and the second rotating shaft 52 are both rotatable relative to the installation frame 31. The protective cloth 32 is wound around the first rotating shaft 51.

[0033] A pull rope 6 is wound around the second rotating shaft 52, one end of the pull rope 6 is arranged on the second rotating shaft 52, and the other end of the pull rope 6 is connected to the protective cloth 32. The second rotating shaft 52 rotates to drive the other end of the pull rope 6 to move. Under the action of the pull rope 6, the protective cloth 32 moves from one side of the installation frame 31 to the other side of the installation frame 31 to cover the photovoltaic panel 2, thereby protecting the photovoltaic panel 2 and preventing direct contact between seawater and the photovoltaic panel 2. Moreover, the operation method is simple and convenient.

[0034] In some embodiments, there are two protective cloths 32 , which are respectively arranged on the top surface of the photovoltaic panel 2 and the bottom surface of the photovoltaic panel 2 to provide all-round protection for the photovoltaic panel 2 and further ensure the service life of the photovoltaic panel 2 .

[0035] In some embodiments, there are two first rotating shafts 51, and the two first rotating shafts 51 are arranged at intervals along the thickness direction of the mounting frame 31; there are two second rotating shafts 52, and the two second rotating shafts 52 are arranged at intervals along the thickness direction of the mounting frame 31; the two first rotating shafts 51 correspond one-to-one with the two second rotating shafts 52, so that the protective cloth 32 located on the top and bottom surfaces of the photovoltaic panel 2 can protect the photovoltaic panel 2 conveniently and quickly, and the operation method is simple.

[0036] In some embodiments, the outer contour of the photovoltaic panel 2 is matched with the inner contour of the installation groove 311 to ensure that the photovoltaic panel 2 is firmly installed in the installation groove 311 and the protective effect of the protective cloth 32 on the photovoltaic panel 2 is ensured.

[0037] In some embodiments, the offshore photovoltaic device also includes a sealing ring (not shown), which is arranged between the photovoltaic panel 2 and the mounting groove 311. The inner circumference of the sealing ring is in close contact with the outer circumference of the photovoltaic panel 2, and the outer circumference of the sealing ring is in close contact with the inner circumference of the mounting groove 311, thereby improving the sealing effect of the photovoltaic panel 2 and further ensuring that seawater is not easy to penetrate into the mounting groove 311.

[0038] In some embodiments, the offshore photovoltaic device further includes a driving member (not shown), which is connected to the first rotating shaft 51 and the second rotating shaft 52 to drive the first rotating shaft 51 and the second rotating shaft 52 to rotate.

[0039] Specifically, by driving the second rotating shaft 52 to rotate around the first direction, the other end of the pull rope 6 is moved from one side of the mounting frame 31 toward the other side of the mounting frame 31, thereby driving the free end of the protective cloth 32 to move from one side of the mounting frame 31 toward the other side of the mounting frame 31 to cover the photovoltaic panel 2 and protect the photovoltaic panel 2.

[0040] By driving the first rotating shaft 51 to rotate around the first direction, the free end of the protective cloth 32 moves from the other side of the installation frame 31 toward one side of the installation frame 31, and the protective cloth 32 is wrapped around the first rotating shaft 51, thereby releasing the protection of the photovoltaic panel 2 and allowing the photovoltaic panel 2 to work normally.

[0041] In some embodiments, the offshore photovoltaic device further includes a control component (not shown), which is connected to the driving component and the installation frame 31 to control the start-up of the driving component and the movement of the installation frame 31 .

[0042] Specifically, in typhoon weather, the protective cloth 32 is covered on the photovoltaic panel 2 through the driving member, and the mounting frame 31 is moved along the guide rail 1 to below the sea surface 72 through the control member, and the inclination angle of the photovoltaic panel 2 is adjusted to ensure that the photovoltaic panel 2 is not easily affected by the typhoon below the sea surface 72. In normal weather, the mounting frame 31 is moved along the guide rail 1 to above the sea surface 72 through the control member, the protection of the photovoltaic panel 2 is released through the driving member, and the inclination angle of the photovoltaic panel 2 is adjusted to make the photovoltaic panel 2 work normally, which is simple and convenient to operate.
