Description
Technical Field
[0001] The utility model belongs to the technical field related to photovoltaic power generation, and specifically relates to an anti-corrosion photovoltaic floating plate. Background Art
[0002] The anti-corrosion photovoltaic floating board is a device specially designed for water-surface photovoltaic power generation systems. Its structural design is designed to improve durability and efficiency when operating in a water environment for a long time. The key components of the floating board include the photovoltaic bracket bottom frame, the floating board metal frame and the hollow plastic floating board. The photovoltaic bracket bottom frame and the floating board metal frame are made of aluminum alloy and covered with an anti-corrosion coating to resist the corrosion in water. Hollow plastic floating boards with a height exceeding their own height are fixed inside the floating board metal frame. These floating boards enable the entire system to float on the water surface through buoyancy. In order to ensure uniform distribution of buoyancy, multiple hollow plastic floating boards are arranged equidistantly inside the photovoltaic bracket bottom frame through the floating board metal frame and fixedly connected by screws to make the entire structure stable and reliable. In addition, a debris blocking frame is provided on the periphery of the photovoltaic bracket bottom frame, and its outer surface is sleeved on both ends and around the bottom frame, and is connected to the bottom frame through multiple fixing screws. The design of the debris blocking frame allows water to enter and exit freely, while effectively blocking debris floating on the water surface to prevent it from adhering to the outer wall of the photovoltaic floating board, thereby reducing corrosion and reducing the frequency of cleaning and maintenance.
[0003] However, the photovoltaic floating panel mainly floats on the water surface, while the solar photovoltaic panel is installed on the photovoltaic floating panel through a photovoltaic bracket. In this way, the photovoltaic floating panel can float and fix the solar photovoltaic panel on the water surface, ensuring that the solar photovoltaic panel is repeatedly exposed to sunlight to generate photovoltaic power. However, because the photovoltaic floating panel needs to float and fix the photovoltaic bracket and the solar photovoltaic panel on the water surface, the photovoltaic floating panel needs to bear the weight and pressure of the photovoltaic bracket and the solar photovoltaic panel. Once the photovoltaic bracket is too large, the weight pressure on the photovoltaic floating panel will increase, and the weight pressure will be concentrated on the photovoltaic floating panel, which will easily cause the photovoltaic floating panel to become loose or even fall off.

[0013] Compared with the prior art, the utility model provides a corrosion-resistant photovoltaic floating plate having the following features:
[0014] Beneficial effects:
[0015] 1. The technical solution of the utility model is to add a plurality of new floating plate reinforcement devices between the floating plate metal frame and the hollow plastic floating plate. After the hollow plastic floating plate is fixed inside the floating plate metal frame, the plurality of new floating plate reinforcement devices can play a role in reinforcing the connection between the hollow plastic floating plate and the floating plate metal frame. The floating plate reinforcement device can more firmly fix the hollow plastic floating plate in the floating plate metal frame, thereby preventing the photovoltaic bracket and the photovoltaic panel from being easily loosened or falling off in the floating plate metal frame due to their heavy weight after being installed on the photovoltaic floating plate. This not only enables the photovoltaic floating plate to bear a larger weight, but also increases the wind resistance resistance;

The technical solution of the utility model is to add a new type of debris blocking frame to the outside of the photovoltaic bracket bottom frame outside the photovoltaic floating board, and the debris blocking frame is fixedly connected to the photovoltaic bracket bottom frame by screws. When the photovoltaic floating board is placed in the water, the debris blocking frame can protect the outside of the photovoltaic bracket bottom frame to play a protective role. The debris blocking frame can block the debris floating on the water outside the photovoltaic bracket bottom frame, and at the same time, the densely distributed water-permeable holes inside the debris blocking frame can allow water to enter and exit. This can ensure that the photovoltaic floating board can float on the water surface normally, and at the same time prevent debris from excessively adhering to the photovoltaic floating board, avoiding the corrosion of the photovoltaic floating board by debris, and at the same time, it can also increase the wind and wave resistance of the photovoltaic floating board by increasing the placement area.

The outer wall of the board can avoid the situation where too much debris is attached to the photovoltaic floating board and affects its floating effect. At the same time, it can also avoid the situation where debris is attached to the outer wall of the photovoltaic floating board and easily corrodes the photovoltaic floating board. The photovoltaic bracket bottom frame 1, the floating plate metal frame 2 and the outer wall of the hollow plastic floating plate 4 are all sprayed with an anti-corrosion coating.

When the hollow plastic floating plate 4 is installed and fixed to the floating plate metal When the floating plate metal frame 2 is inside the hollow plastic floating plate 4, it is necessary to place the floating plate metal frame 2 on the upper side of the hollow plastic floating plate 4, and then align the reinforcing connecting screws 12 at the bottom ends of the multiple metal reinforcing strips 11 with the multiple sealed metal sleeves 10 inside the hollow plastic floating plate 4, and then insert the reinforcing connecting screws 12 into the sealed metal sleeves 10 until the sleeve groove 9 inside the top of the hollow plastic floating plate 4 is sleeved on the outside of the metal reinforcing strips 11, at this time, the bottom end of the reinforcing connecting screw 12 is exposed outside the bottom end of the hollow plastic floating plate 4, and then the internal thread tray 13 is sleeved on the bottom of the reinforcing connecting screw 12 The outside of the end is tightened, and the internal threaded tray 13 is tightened until the internal threaded tray 13 is tightly clamped on the outer wall of the bottom end of the hollow plastic float 4.
