Water Photovoltaic Mounting System

Abstract

The invention provides a waterborne photovoltaic support system. The waterborne photovoltaic support system comprises buoyancy tanks (1), two ends of the top surface or two side surfaces of each buoyancy tank (1) are provided with photovoltaic plate installation parts, each two buoyancy tanks (1) form a platform unit, the buoyancy tanks (1) of the same platform units are connected via a plurality of connecting pieces (7), and the adjacent platform units are connected in a fastening manner via the connecting pieces or matching structures on the adjacent side surfaces of the buoyancy tanks (1). According to the waterborne photovoltaic support system, a photovoltaic plate (8) is arranged above a water area between the two buoyancy tanks (1), double continuous circulation cooling of the photovoltaic plate is realized by fully employing the continuous circulation water-cooling principle between the photovoltaic plate and the water surface, the output power of the photovoltaic plate is increased, and the lifetime of the material of the photovoltaic plate is extended.

Description

technical field [0001] The present invention relates to photovoltaic power generation, in particular to a photovoltaic support system on water. Background technique [0002] my country is one of the few countries in the world that uses coal as the main energy source. About 65% of primary energy production and consumption is coal, and a large amount of coal is used, so that 66% of China's urban air particulate matter content and 22% of urban air sulfur dioxide content exceed The national air quality secondary standard. The use of coal and fossil energy emits a large amount of pollutants, leading to air pollution and acid rain pollution, which has seriously deteriorated the air quality of Chinese cities. China has 16 of the 20 most polluted cities in the world listed in the 2001 World Bank Development Report. In areas with severe air pollution, the total mortality and incidence of respiratory diseases are higher than those in lightly polluted areas. Symptoms of chronic bronc...

Problems solved by technology

However, because the western region is far away from the load center, the problem of solar abandonment of photovoltaic power plants in some regions has not been well resolved.

[0005] At present, foreign countries and domestics basically use large-scale ground photovoltaic power plants to generate electricity and rooftop photovoltaic power generation models, and hardly use water surface resources for photovoltaic power generation. The only design is to build a floating body composed of several small floating bodies on the water. For the floating platform with gaps, photovoltaic panels are directly laid on the floating platform or metal brackets are built on the floating platform to install photovoltaic panels. Such a design scheme is not effective in wind pressure and wave resistance, and uses the principle of air cooling, resulting in The power generation efficiency of photovoltaic panels is not high, which has always limited the application and development of photovoltaic power plants on water
