Description

An environment-friendly multifunctional pedal plug-in water surface photovoltaic power generation system

technical field

The utility model relates to the technical field of photovoltaic power generation, in particular to an environment-friendly multifunctional pedal plug-in water surface photovoltaic power generation system.

Background technique

Photovoltaic power generation system uses solar energy to form a power generation system for electronic components such as crystalline silicon panels and inverters. It is an environmentally friendly, safe and reliable green energy source. Photovoltaic power plants are currently the most encouraged green power development energy projects by the state, and have made important contributions to building a low-carbon society. However, due to the low energy density of photovoltaic power generation and the large footprint under the same capacity configuration, it is difficult for terrestrial photovoltaics to rationally allocate land resources. However, there are a large number of reservoirs, lakes, and mining subsidence areas in our country. Using their idle water surface space to build floating photovoltaics is an optimal use of resources. It can not only make rational use of land resources, increase power generation, but also protect the water environment and reduce floating dust.

The environment of floating photovoltaic power plants on water is humid, and the structural components are prone to corrosion. In order to ensure the corrosion resistance and longevity of floating objects, hollow blow-molded high-density polyethylene floating bodies are generally used to provide buoyancy for surface photovoltaic power plants. The structural form of hollow blow molding products has a great influence on production efficiency and quality. A flat structure with uniform thickness is most conducive to blow molding into a floating body with uniform wall thickness. The photovoltaic power station needs to use floating objects to support the photovoltaic modules at a certain angle, which creates special shape requirements for the floating objects. At present, most floating body structures at home and abroad only consider meeting the inclination angle requirements of power generation, while ignoring the unfavorable factors for production and quality control. How to optimize the design of the floating body structure to meet the requirements of use and facilitate production is a problem that needs to be solved at present.

Since 2015, my country's water surface photovoltaic technology has developed rapidly, especially in the coal mining subsidence area of the Lianghuai area. At present, the construction of several water surface photovoltaic power stations has been completed. However, the water area in the subsidence area is limited, and it is difficult to meet the construction needs of water surface photovoltaic power stations. Many water surface photovoltaic power stations are gradually developing to water surface areas such as reservoirs and lakes. Different from subsidence areas, reservoirs, lakes and other water areas integrate many functional platforms such as water supply and breeding. If they are in the form of floating bodies similar to subsidence areas, the water surface area will be blocked by a large area, hindering the flow of air, sunlight and water. Contact will cause hypoxia in the water body and lead to the death of aquatic organisms. Therefore, under the premise of ensuring the quality, function and stability of the floating body, reducing its shading to the water surface and improving the light transmission and hydrophilicity of the floating body are problems that need to be solved in the development of water surface photovoltaic technology.

At present, most of the designs of water surface photovoltaic floating bodies proposed at home and abroad are considered from the perspective of installation and fixation, but from the perspectives of floating body structure rationality, versatility, and environmental friendliness, there are still some problems in these design schemes. Patents such as WO2012/139998A2, CN201520911191.7, CN201520618986.9 and other patents disclose that the upper surface of the water surface photovoltaic floating body is designed as a slope to meet the requirements of the inclination angle of the photovoltaic module; however, the slope design destroys the flatness of the structure of the blow molding product, resulting in uneven wall thickness While affecting the quality of the floating body, its fixed slope angle and installation method also limit the installation and fixing of other electrical equipment on the water, and the continuous operation and maintenance channel in the form of this floating body will cause serious blocking of the water surface. Patents such as CN201620418220.0, CN201620220867.2 and other patents disclose photovoltaic floating bodies on the water surface are relatively flat design methods, and the photovoltaic modules are supported at a certain inclination angle by independent supports; The utility model is beneficial to the use of the floating body in lakes, reservoirs and other areas.
