Description
Technical Field
The invention relates to the technical field of photovoltaic power generation, in particular to an ultralong weather-proof water surface photovoltaic platform system and an installation method.
Background
With the strong development of photovoltaic power stations in recent years, the photovoltaic resources on the ground are becoming more and more scarce, and the construction of the photovoltaic power stations on the ground is gradually going to mountains, forests, roofs and the like. The electricity demand of the economic developed provinces in the middle east is larger, meanwhile, the water surface resources such as idle rivers and lakes are very rich, the water surface space is utilized to construct the water surface photovoltaic power station, the generated energy of the photovoltaic power station can be improved, the water environment is protected, and the land resources are reasonably optimized.
The investment construction of the water surface photovoltaic power station starts from home and abroad in 2014, and the water surface photovoltaic power station is built in a step-by-step test mode in coal mining subsidence areas such as two-Huai-Shandong. As a supporting platform of the solar photovoltaic panel, the hollow floating platform formed by blow molding of high-density polyethylene is most commonly used in China at present, and floating platforms which are pushed out by various manufacturers in China are also in a hundred-flower and uniform form. Because the operation period of the photovoltaic power station is 25 years, compared with the ground photovoltaic power station, the service life of the floating platform is the most concerned by the owner investor. The high-density polyethylene is used as a most common polymer material in the market, and has the biggest defect of easy ultraviolet aging after long-term outdoor use, thereby causing embrittlement, cracking and damage of products. The existing floating bodies are mostly hollow blow molding products, and the aging damage of the products has great influence on the long-term operation of the water surface photovoltaic power station. At present, manufacturers and research institutions improve the weather resistance of the floating body from the angle of optimizing the formula of the floating body, but because the laboratory ageing research period of high-density polyethylene is longer, but no high-density polyethylene product with 25 years of experience is used as a reference in the market at present, how the long-term use performance of the hollow blow molding floating platform is, at present, still exists in an exploration stage, and the investment confidence of each investor on a water surface photovoltaic power station is limited to a certain extent.
On the other hand, as the water terminal industry which has earlier used high density polyethylene hollow blow molded products, there is also experience in pouring plastic foam in hollow blow molded products. The plastic foam does not absorb water, resists ultraviolet aging, has long service life, and can ensure that the floating body floats even under the condition that the high-density polyethylene shell of the floating body is aged and damaged, thereby ensuring the safe operation of the power station. Regarding the choice of filling plastic foam material, one is to use polyurethane materials, but there are three major drawbacks: 1. polyurethane foam is high in cost, and the use of the polyurethane foam in the engineering field is limited; 2. the polyurethane foam is filled in a mode of filling after the floating body is formed, and the floating body of the water surface photovoltaic is in an irregular shape due to the foaming principle of polyurethane, so that the inside of the floating body is easily filled unevenly, and uneven parts are easily broken; 3. because of the non-uniformity of foaming, continuous air holes are easily formed in the foam part area, the water absorption rate of the foam is improved, the foam absorbs water under the condition that the shell of the floating body is damaged, and the supporting effect of the floating body is lost. The other is to use polyvinyl chloride plastic foam (EPS), in a formed rotational molding buoyancy tank, foam particle raw materials are expanded and filled through high-pressure steam, and the filling is uneven due to the adoption of a post-filling mode, and the filling efficiency is low.
At present, a floating body in a foam filling form is adopted in China, a traditional foam filling process is still adopted, a shell of the floating body comprises a high polymer material, a metal material and the like, the floating body is low in production speed, complex in product form, more in various components and high in product cost, and engineering construction difficulty is improved. Patents such as CN204432959 and CN202132648 only mention foam filling, and the preliminary conceptual stage of research and development is still in question as to how to adapt to the production and installation of the surface photovoltaic floating body and how to reduce the manufacturing cost.
