Combined noise shield with integrated solar panels

Abstract

The article is devoted to the assessment of the noise load of road transport on the environment of large cities. Goal. The goal is to develop engineering structures to neutralize harmful substances from internal combustion engines, display and absorb sound waves, ensure road safety and improve energy efficiency. Methodology. The experience of European countries on the use of noise protection screens with integrated solar batteries is presented. The types and design features of solar panels are presented. Results. A model of a combined noise protection barrier with integrated solar batteries is proposed. This screen can be used to protect the urban environment from noise, sound waves and chemical compounds of internal combustion engines. Originality. The combined noise barrier with integrated solar panels is an engineering structure consisting of a foundation, sound-absorbing, sound-reflecting modules and solar cells, which differs in that it has a Y-shaped profile equipped with metal perforated modules filled with sound-absorbing material (polymers of organic origin , composite materials, mineral fibers, etc.) and sound-reflecting transparent or translucent modules, installed on a foundation made of photocatalytic concrete, and the energy obtained from the solar panels is transferred to street lights, which are installed on the foundation of the screen. Practical value. The invention can be used to protect against noise, sound waves and chemical compounds of exhaust gases of internal combustion engines of urban environment, residential buildings and pedestrian areas.
