Their function is to support photovoltaic modules floating on the sea surface and maintain stability, thereby achieving efficient conversion of solar energy. However, in the marine environment, salt spray deposition is a common pollution problem faced by photovoltaic panels. This pollution is caused by the migration and adsorption of salt particles in the atmosphere, which poses a significant threat to photovoltaic panels.

[0003] Salt crystals will block and scatter sunlight, reducing light transmittance. If not cleaned for a long time, power generation will drop significantly. At the same time, the chloride ions and other components contained in the salt will corrode the aluminum alloy frame and junction box metal parts, causing pitting and poor contact. They will also corrode the sealant and back panel, destroying the structural sealing. In addition, uneven salt deposition can easily cause hot spot effects, accelerate the aging of battery cells, shorten the life of the panels, and increase cleaning and maintenance costs.

For example, when the floating bracket 1 is set in the east-west direction, when the sun rises from the east, the photovoltaic bracket 3 and the photovoltaic panel 4 are tilted forward to correspond to the position of the sun. When the sun moves to the west, the photovoltaic bracket 3 and the photovoltaic panel 4 are tilted backward, so that the photovoltaic panel 4 can better receive sunlight and improve the efficiency of photovoltaic power generation.

[0034] For example 2, please refer to Figures 1 to 8The difference between the embodiment 1 and the embodiment 1 is that a wetting assembly 6 is movably mounted in the middle of the floating support 1.

[0035] The scrubbing assembly 7 includes a screw rod 701, a support beam 1 702, a support beam 2 703, a stepper motor 704 and a bearing 1 705.

The output shaft of the stepper motor 704 is fixedly connected to one end of the screw rod 701, so that the stepper motor 704 can easily drive the screw rod 701 to rotate.

[0036] A limiting groove 102 is provided in the middle position of the floating support 1, and the brushing assembly 7 also includes a slide 706, a screw hole 7061, a limiting strip 7062, a swing frame 707, a second rotating rod 708 and a second bearing 709.

The second rotating rod 708 is rotatably connected to the slide 706 through the second bearing 709, and the lower position of the slide 706 is slidably connected in the limiting groove 102, so that the swing frame 707 swings left and right at the side position of the slide 706. The lower end of the slide 706 is stuck in the limiting groove 102, so that the slide 706 cannot rotate, and the slide 706 moves along the screw rod 701.

[0037] The brushing assembly 7 also includes a barrel rod 710, a roller brush 711 and a limiting head 712. The barrel rod 710 is fixedly connected to one side of the swing frame 707, and the roller brush 711 is rotatably connected to the barrel rod 710. The side of the roller brush 711 is covered with bristles, and the roller brush 711 brushes the photovoltaic panel 4. The limiting head 712 is fixedly connected to the swing frame 707 and is located on the other side of the barrel rod 710. The limiting head 712 is located on the side of the slide 706 and below the limiting strip 7062. The limiting head 712 contacts the slide 706 downward to stop rotating downward. The limiting head 712 rotates upward and contacts the limiting strip 7062 to stop rotating upward.

[0038] The bottom surface of the floating support 1 is fixedly connected to the mounting frame 104. The wetting assembly 6 also includes a detergent box 601, an addition port 602, a sealing cover 603, a water pump 604, a water pump pipe 605 and a water outlet pipe 606. The detergent box 601 is fixedly connected to the mounting frame 104. The detergent box 601 is filled with detergent, such as fresh water. The addition port 602 is fixedly connected to the detergent box 601. The sealing cover 603 is threadedly connected to the addition port 602. The addition port 602 is fixedly connected to the detergent box 601. To facilitate the addition of detergent into the detergent box 601, the sealing cover 603 seals the adding port 602, and the water pump 604 is fixedly connected to the detergent box 601. The water inlet of the water pump 604 is inserted into the detergent box 601 through the water pumping pipe 605, and the lower end of the water pumping pipe 605 extends into the lower position of the detergent box 601. The water outlet of the water pump 604 is fixedly connected to the water outlet pipe 606, so that the water pump 604 can easily extract the detergent in the detergent box 601 and pass it into the water outlet pipe 606.

[0039] The wetting component 6 also includes a tee 607, a hose 608, a fork tube 609 and a drain outlet 611. One end of the tee 607 is connected to the outlet pipe 606, and the other two ends of the tee 607 are respectively connected to the hose 608. The fork tube 609 is fixedly connected to the hose 608. The fork tube 609 is connected to the drain pipe 610. The drain outlet 611 is opened on the drain pipe 610. The drain pipe 610 is fixedly connected to the other side of the swing frame 707. The drain outlet 611 discharges the liquid in the drain pipe 610.

[0040] The present invention uses the following steps: The offshore photovoltaic floating device starts the water pump 604, which pumps liquid from the detergent tank 601 and discharges it into the drain pipe 610 through the outlet pipe 606, the tee 607, the hose 608, and the bifurcated pipe 609. The drain pipe 610 then discharges liquid through the drain port 611. As the liquid enters the drain pipe 610, the weight of the drain pipe 610 increases. At this point, the overall weight of the drain pipe 610 is heavier than the weight of the roller brush 711 and the rod 710, causing the swing frame 707 to rotate on the swing frame 707 via the second rotating rod 708 and the second bearing 709. The limiting head 712 moves upward and contacts the limiting strip 7062. The stepper motor 704 drives the screw rod 701 to rotate, and the slide 706 moves along the screw rod 701, so that the slide 706 drives the swing frame 707 and the drain pipe 610 thereon to move synchronously. The drain pipe 610 and the roller brush 711 are located on one side of the photovoltaic bracket 3. When the photovoltaic bracket 3 and the photovoltaic panel 4 are adjusted to a horizontal state, the drain pipe 610 is moved from one side of the photovoltaic panel 4 to the other side to rinse the salt stains on the photovoltaic panel 4, so that some salt stains with weak binding strength are easily removed by the liquid, and the remaining salt stains with strong binding strength are easily moistened and softened; When the drain pipe 610 moves to the other side, the water pump 604 stops extracting detergent from the detergent tank 601, and the screw rod 701 stops rotating, so that the detergent on the horizontal photovoltaic panel 4 has sufficient time to moisten and soften the salt stains. At this time, since the liquid in the drain pipe 610 is discharged, the weight of the drain pipe 610 is reduced, and the weight of the roller brush 711 and the rod 710 is heavier than the weight of the drain pipe 610, causing the swing frame 707 to rotate in the opposite direction, and the roller brush 711 rotates downward, and the limiting head 712 contacts the sliding frame 706 downward, so that the roller brush 711 stops rotating downward. Then the stepper motor 704 rotates the screw rod 701 in the opposite direction, causing the slide 706 to move in the opposite direction, driving the roller brush 711 to move on the photovoltaic panel 4. The bristles on the roller brush 711 brush the photovoltaic panel 4, making it easier to remove the moistened and softened salt stains, making the salt stains on the photovoltaic panel 4 more thoroughly removed, and avoiding the salt stains from affecting the power generation of the photovoltaic panel 4.

After the lightweight float 2 is scrapped, the foam aluminum core layer 201 can be recycled by electrolytic separation (recovery rate > 95%). The T700 carbon fiber / epoxy resin (60:40 vol%) is coated on the surface of the foam aluminum core layer 201 by vacuum infusion process to form a fiber-reinforced composite layer 202, and polyurethane is sprayed.
