DETAILED DESCRIPTION

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] Example 1: Please refer to Figure 1-4 The utility model provides a technical solution: a floating pond photovoltaic device, including a floating platform 1, which is composed of a plurality of floating components 2 spliced ​​together. A fixing cylinder 3 is provided below the center of the bottom of the floating platform 1, and a fixing ring 4 is fixedly connected to the top of the fixing cylinder 3. A fixing steel cable 5 is fixedly connected between the fixing ring 4 and the bottom of the floating platform 1. The fixing cylinder 3 is semicircular, and a traction steel cable 6 is passed through the fixing cylinder 3. One end of the traction steel cable 6 is fixedly connected to a first anchor block 7, and the other end of the traction steel cable 6 is fixedly connected to a second anchor block 8. A photovoltaic device 9 is installed on the top of the floating platform 1. The first anchor block 7 sinks to the bottom of the water, and the second anchor block 8 is suspended in the water. The weight of the first anchor block 7 is much greater than that of the second anchor block 8. The gravity of the second anchor block 8 accounts for 20-40% of the bearing weight of the floating platform 1, ensuring that the second anchor block 8 has a certain traction capacity for the floating platform 1. When the water level drops, the second anchor block 8 drives the traction cable 6 to slide in the fixed tube 3, shortening the distance between the floating platform 1 and the first anchor block 7. When the water level rises, under the action of the buoyancy of the floating platform 1, the first anchor block 7 moves upward as a whole. However, due to the gravity of the second anchor block 8, the surface of the traction cable 6 is still in a taut state, thereby ensuring that the floating platform 1 can maintain a certain stability while adapting to water level changes.

[0020] The floating component 2 includes a buoyancy box 21, and a rotating fixed seat 22 is fixedly connected to the top side of the buoyancy box 21. A photovoltaic support panel 23 is rotatably connected inside the rotating fixed seat 22. An adjustment seat 24 is provided on the top side of the buoyancy box 21. The adjustment seat 24 includes a fixed plate 241, and a rotating seat 242 is fixedly connected to the top side of the fixed plate 241. A long hole 243 is opened on the surface of the fixed plate 241, and anti-slip teeth 244 are also provided on the bottom of the fixed plate 241. A support rod 25 is rotatably connected between one side of the top of the adjustment seat 24 and the photovoltaic support panel 23, and a pressure plate 26 is fixedly connected to the top of the adjustment seat 24. A fastening bolt 27 threadedly connected to the buoyancy tank 21 is provided on the top of the pressure plate 26. The fastening bolt 27 is set in the long hole 243, and the anti-slip teeth 244 increase the friction between the fixed plate 241 and the buoyancy tank 21, ensuring the stability of the adjustment seat 24. When adjusting the angle, loosen the fastening bolt 27, adjust the position of the adjustment seat 24 along the length direction of the long hole 243, change the angle of the photovoltaic support panel 23 by the support rod 25, and fix the adjustment seat 24 by the fastening bolt 27 after adjustment. By adjusting the angle of the photovoltaic support panel 23, the light receiving efficiency of the photovoltaic device 9 is improved, thereby improving the power generation efficiency.

[0021] The two adjacent ends of the pontoons 21 are provided with connecting protrusions 28, and the other adjacent ends of the pontoons 21 are provided with connecting grooves 29 that adapt to the connecting protrusions 28. When connected, the connecting protrusion 28 on one end of the pontoon 21 is connected to the connecting groove 29 on the adjacent pontoon 21. A clamping groove 210 is provided at the top of the pontoon 21 and near the edges. A connecting plate 211 is provided in the clamping groove 210 between the two pontoons 21. Connecting bolts 212 are provided between the connecting plate 211 and the pontoon 21. A connecting seat 213 is fixedly connected to the bottom of the pontoon 21, and one end of the fixed steel cable 5 is fixedly connected to the connecting seat 213. The connecting plate 211 and the connecting bolts 212 prevent relative movement between the two adjacent pontoons 21, thereby ensuring the reliability of the connection.
