Super-long weather-resistant surface photovoltaic platform system and installation method thereof

Abstract

The invention discloses a super-long weather-resistant surface photovoltaic platform system and an installation method thereof. The system includes a connecting floating body, a support floating bodyand a photovoltaic module which are arranged above that connecting floating body. The lower end of the support floating body is inserted and matched with the hollowed-out part of the connecting floating body, and the upper and lower ends of the photovoltaic module are respectively fixedly connected with the support floating body and the connecting floating body through an upper connector and a lower connector; the connecting floating bodies are arranged in rows and columns, and the connecting floating bodies between adjacent rows and columns are connected with the walkway floating body. According to the invention, the middle part of the connecting floating body is subjected to a hollowing out process, under the premise of satisfying the support of the photovoltaic module and the running buoyancy of the power station, the connecting floating body provided by the invention enlarges the area of the water body contacting the air, improves the light transmittance of the whole floating bodyplatform system, ensures the normal growth of aquatic organisms, and is favorable for the popularization of the surface photovoltaic power generation system. The hollowed-out treatment of the connected floating body also improves the hydrophilicity of the photovoltaic module, which can effectively ventilate and cool the module, thereby improving the power generation efficiency.

Description

technical field [0001] The invention relates to the technical field of photovoltaic power generation, in particular to an ultra-long weather-resistant water surface photovoltaic platform system and an installation method. Background technique [0002] With the vigorous development of photovoltaic power stations in recent years, ground photovoltaic resources have become increasingly scarce, and the construction of ground photovoltaic power stations has gradually moved to mountains, forests, and roofs. Economically developed provinces in the central and eastern regions have a large demand for electricity. At the same time, idle rivers and lakes and other water surface resources are very rich. Using water surface space to build water surface photovoltaic power plants can increase the power generation of photovoltaic power plants, protect the water environment, and rationally optimize land resources. [0003] Since 2014, the investment and construction of water surface photovolt...

Problems solved by technology

Regarding the choice of filling plastic foam material, one is to use polyurethane material, but there are three major defects: 1. The cost of polyurethane foam is high, which limits its use in the engineering field; , due to the foaming principle of polyurethane, and the photovoltaic floating bodies on the water surface are mostly irregular shapes, it is easy to cause uneven filling inside the floating body, and the uneven parts are easy to break; 3. Due to the uneven foaming, it is easy to cause continuous pores in some areas of the foam , the water absorption rate of the foam is improved, and the foam absorbs water when the shell of the floating body is damaged, and the supporting function of the floating body is lost

The other is to use polyvinyl chloride plastic foam (EPS). In the formed rotationally molded floating tank, the foam particle raw material is expanded and filled by high-pressure steam. Due to the use of post-filling filling, uneven filling will also occur. , and the filling efficiency is very low

[0005] At present, the floating body in the form of foam filling is still used in the country, and the traditional foam filling process is still used. The floating body shell contains polymer materials and metal materials. The difficulty of engineering construction
