Embodiment 1

[0039] This embodiment provides a floating body for a photovoltaic power generation system on water, which includes a foam material, and the foam material is coated with an interface adhesive 2 and a water blocking layer 1 sequentially from the inside to the outside.

[0040] The floating body for the floating photovoltaic power generation system provided in this embodiment is composed of a foam material, an interface adhesive, and a water blocking layer 1 , and has a "solid structure" as a whole, which is flexible and convenient to process. Among them, the foamed material is pressure-resistant, light in weight, and provides high buoyancy; the surface of the foamed material is treated with an interface cement 2 to close the surface gap and improve the cohesive force and sensory quality between the inner and outer layer materials; the outer surface of the foamed material Coating the water blocking layer 1 reduces the water absorption rate of the floating body 8 and improves the ...

Embodiment 2

[0042] On the basis of Embodiment 1, this embodiment provides a floating body for photovoltaic power generation system on water, the floating body 8 is a cuboid, and the cuboid is composed of an upper part and a lower part, and the upper part and the lower part are combined through the tooth groove 19 , the density of the foam material used in the upper part is greater than that of the lower part, and the upper part is divided into a connection reserved hole 1 and a connection reserved hole 2, and the connection reserved hole 1 and the connection reserved connection hole 2 are axially perpendicular .

[0043] Such as figure 1 As shown, the upper part adopts a density of 25~40Kg / m 3 High-density foam material 3, the lower part adopts a density of 18~20Kg / m 3 The low-density foam material 4 is bonded between the two to form an integral core material through the alveolar 19, and the combination of different densities can reduce the cost, and different density grades can be sele...

Embodiment 3

[0046] On the basis of Embodiment 1, this embodiment provides a floating body for a photovoltaic power generation system on water, and the floating body 8 is a cylinder.

[0047] Such as figure 2 As shown, the cylindrical floating body 8 is a whole, the surface of the cylindrical body is treated with the interface cement 2, and the outermost layer is covered with the water blocking layer 1.

Abstract

The invention belongs to the technical field of photovoltaic power generation, and provides a floating body for an overwater photovoltaic power generation system, a floating supporting system formed by the floating body and a floating supporting method. The interior of the floating body is a foaming material, and the outer surface of the floating body is coated with an interface cementing agent and a waterproof layer. The whole floating body is of a solid structure and is in the shape of a cuboid and a cylinder. The foaming material adopts flame-retardant molded polystyrene foam plastic, extruded polystyrene foam plastic or polyurethane foam plastic, is light in weight and small in heat conductivity, provides huge buoyancy and serves as a carrier for providing buoyancy of the floating body; the waterproof layer is sprayed with polyurea elastomers, the coating is continuous and seamless, and the coating is good in waterproof permeability resistance, adhesive force, weather resistance, salt mist resistance, aging resistance and abrasion resistance, and is adjustable in the hardness; and after the floating body is wrapped by the waterproof layer, the water absorption rate of the floating body can be obviously reduced, and the impact strength of the floating body is improved. And the foaming material and the waterproof layer are treated by the interface cementing agent, so that a surface gap can be closed, and the bonding force and the sensory quality between inner and outer layer materials are improved.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and in particular relates to a floating body and a floating support system and method for a photovoltaic power generation system on water. Background technique [0002] At present, in the floating water photovoltaic power generation system, the types of floating bodies that have a supporting function and make the photovoltaic power generation system float on the water surface include metal buoys, concrete buoys, glass fiber reinforced plastic buoys, HDPE (high-density polyethylene) floating bodies, etc., among which HDPE floating bodies 8 widely used at home and abroad. [0003] The current conventionally designed floating bodies and systems mainly have the following problems: [0004] 1) The cost of the floating body and its supporting system is high, and it is difficult to adapt to the development of domestic and foreign photovoltaic power generation to the parity and bid...
