Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the protection scope of the present application.

[0041] Embodiment one

[0042] Please refer to Figures 1 to 4 A water-floating solar photovoltaic device includes a float frame table 1 and a photovoltaic panel body 2 arranged on the float frame table 1. The photovoltaic panel body 2 is fixedly installed on the float frame table 1. In the present application, the float frame table 1 is provided with a plurality of float frame tables 1, which are preferably arranged in a circular table shape. Each float frame table 1 is correspondingly provided with a photovoltaic panel body 2. The plurality of float frame tables 1 are stably connected with each other to form a cluster of photovoltaic panel bodies 2. An anchoring device is further arranged at the bottom of the water. The anchoring device is an existing device, which is used to ensure that the cluster of float frame tables 1 stably float on the water.

[0043] Please refer to Figures 4 to 10The floating body rack 1 is provided with a through hole at the center position, and a rust-proof cylinder 3 is fixedly installed at the through hole. The rust-proof cylinder 3 is communicated with a water supply pipe 4 at the top, and one end of the water supply pipe 4 is connected with a water pump 41. In the present application, a plurality of floating body racks 1 are provided. The water supply pipes 4 between the plurality of floating body racks 1, i.e. the water supply pipes 4 of each row, are communicated through the rust-proof cylinder 3. Each column can additionally be provided with a parallel pipe for synchronously supplying cleaning liquid to the water supply pipes 4 of each row. The cleaning liquid can be fresh water or cleaning liquid for cleaning the surface of the photovoltaic panel body 2, such as photovoltaic panel cleaning agent 1150P. The water pump 41 is communicated with a water tank containing cleaning liquid, and the cleaning liquid is transmitted by the operation of the water pump 41.

[0044] The rust-proof cylinder 3 is internally provided with a movable piston 5 made of corrosion-resistant metal material. The movable piston 5 can slide up and down relative to the rust-proof cylinder 3 and block the rust-proof cylinder 3. A rotating block 51 is penetrated through the center of the movable piston 5 and rotationally connected with the movable piston 5. A conversion inlet piece 6 is installed at the top of the rotating block 51. The rust-proof cylinder 3 is also communicated with a water guide pipe 31 which penetrates through the floating body rack 1 and is connected with a cleaning piece 7 at the top. The cleaning piece 7 is used for cleaning the surface of the photovoltaic panel body 2.

[0045] The conversion inlet piece 6 comprises an inlet shell 61, a rotating rod 62 and rotating leaves 63. The rotating rod 62 is fixedly installed at the top of the rotating block 51 and rotationally connected inside the inlet shell 61. The inlet shell 61 is connected inside the rust-proof cylinder 3.

[0046] The rotating leaves 63 are provided in plurality and equidistantly distributed outside the rotating rod 62. The inlet shell 61 is provided with a water inlet hole 611 at the top and a water outlet hole 612 at the bottom and offset from the water inlet hole 611.

[0047] Two guide strips 32 are fixedly installed inside the rust-proof cylinder 3. The inlet shell 61 and the movable piston 5 are provided with guide grooves 33 corresponding to the positions of the guide strips 32. The guide strips 32 can prevent the rotation of the inlet shell 61 and the movable piston 5 and ensure that the inlet shell 61 and the movable piston 5 can stably move vertically upward or downward inside the rust-proof cylinder 3.

[0048] A positioning baffle 34 is fixedly installed inside the rust-proof cylinder 3 and located below the water guide pipe 31. The positioning baffle 34 is used for limiting the movable piston 5.

[0049] Specific implementation process: In this application, when it is necessary to clean the bottom and edges of the floating platform 1, the water pump 41 is operated, thereby introducing the cleaning fluid into the rust-proof cylinder 3 through the water supply pipe 4. The cleaning fluid enters the rust-proof cylinder 3 and is located above the inlet shell 61. It enters through the water inlet 611. At the same time as entering the water inlet 611, due to the current limitation of the rotating blade 63, the flowing cleaning fluid synchronously pushes the rotating blade 63 to rotate. Multiple rotating blades 63 drive the rotating rod 62 to rotate. When the rotating rod 62 rotates, the rotating scraper 8 is driven to run through the rotating block 51.

[0050] When the water flows into the upper part of the moving piston 5, the water pressure generated will push the moving piston 5 to move down along the rust removal cylinder until the bottom of the moving piston 5 moves onto the positioning retaining ring 34. At this time, the cleaning fluid enters the water guide pipe 31 and enters the cleaning part through the water guide pipe 31. As the cleaning fluid flows, it will continuously drive the rotating rod 62 and the rotating block 51 to rotate continuously.

[0051] The cleaning component 7 includes a bent pipe 71 and a spray pipe 72.

The multiple spray holes 721 face the outer surface of the photovoltaic panel body 2.

[0052] Specifically: when water flows into the water guide pipe 31, it enters the bend pipe 71 through the water guide pipe 31 and is sprayed out through the spray pipe 72. In this application, a nozzle is also installed at the spray hole 721 so that the sprayed cleaning liquid is fully distributed on the surface of the photovoltaic panel body 2, thereby achieving the function of regularly spraying and cleaning the photovoltaic panel body 2, preventing the photovoltaic panel body 2 from being exposed to the outdoors for a long time, which would cause bird droppings and other impurities to adhere to its surface, and further ensuring the power generation efficiency of the photovoltaic panel body 2.

[0053] The bottom of the rotating block 51 is connected to a rotating scraper 8, which is used to scrape off shellfish and algae attached to the bottom and edges of the floating platform 1.

[0058] The pushing piece 844 is connected with the sealed triangular shell 843, and the pushing piece 844 is slidingly connected at the bottom of the floating body frame 1.

The other end of the extension rod 8445 is slidably connected with the containing groove.

[0062] The arc-shaped scraper 8444 is provided with an arc-shaped opening 9. The top of the arc-shaped opening 9 is provided with a removal plate 91. In the present application, the side of the removal plate 91 close to the floating body frame 1 is provided with a scraping step, so that the removal plate 91 can be in contact with and separated from the floating body frame 1. The bottom of the removal plate 91 is provided with a floating plate 92, and the floating plate 92 is slidably connected at the arc-shaped opening 9.

[0063] Specific implementation process: in the present application, when the moving piston 5 moves downward, the moving rod 81 is simultaneously driven to vertically move downward along the rust-proof cylinder 3.

The push frame 82 pushes the plurality of connecting shafts 845 through the plurality of push openings 821 on the edge thereof. When the connecting shafts 845 are pushed, the sealed triangular shell 843 rotates around the fixed shaft 842 under the limiting action of the connecting shafts 845. At this time, one end of the sealed triangular shell 843 containing the counterweight 846 gradually moves upwardly and obliquely. At the same time, the connecting frame 8441 is pushed by the guide shaft 8442. At this time, the connecting frame 8441 moves while simultaneously pushing the arc-shaped scraper 8444. The arc-shaped scraper 8444 moves along the edge of the floating body frame 1 under the limiting action of the extension rod 8445 until the arc-shaped opening 9 of the arc-shaped scraper 8444 deviates from the edge of the floating body frame 1. At this time, the removal plate 91 moves vertically upward along the edge of the floating body frame 1 under the buoyancy of the floating plate 92. As the rotating block 51 drives the moving rod 81 to rotate, the moving rod 81 drives the push frame 82, the positioning scraping frame 83, and the plurality of arc-shaped scrapers 8444 to rotate relative to the bottom and the edge of the floating body frame 1, thereby fully scraping the shellfish and algae attached to the bottom and the edge of the floating body frame 1.
