Solar photovoltaic power generation pavement and application thereof

Abstract

The invention provides a solar photovoltaic power generation pavement and an application thereof. The solar photovoltaic power generation pavement at least comprises a subgrade, a base course, a surface course, a solar photovoltaic power generation layer and a light-transmitting friction course in sequence from bottom to top. According to the solar photovoltaic power generation pavement and the application thereof, a solar photovoltaic power generation technique can be organically integrated under the circumstance of ensuring vehicle safety operation so as to realize coordinated operation of a road traffic function and a photovoltaic power generation function.

Description

technical field [0001] The invention relates to a solar photovoltaic power generation surface and an application thereof. Background technique [0002] The key technology of solar photovoltaic power generation surface is: (1) how to protect the photovoltaic panels arranged on the road surface from being damaged when they are crushed by vehicles; Vehicle driving friction; (3) Other auxiliary layers play the functions of buffering, wiring, insulation and so on. At present, there are three main types of solar photovoltaic pavement technologies at home and abroad: solar "bricks" in the United States, prefabricated cement concrete photovoltaic panels in the Netherlands, and direct-buried photovoltaic pavement in France. [0003] In 2006, Scott Brushaw and Julie, a couple of scientists in Idaho, USA, first proposed the dream of building a so-called "solar road" with solar panels instead of traditional asphalt. , and received research and development funding from the US Federal H...

AI Technical Summary

Problems solved by technology

This kind of pavement structure has the basic level and function of solar photovoltaic power generation surface, but its pavement structure level function positioning is vague, and there are no specific design requirements and indicators, it is easy to cause large-area photovoltaic panels to break during use, and it is difficult to be widely used

[0006] The above three types of solar photovoltaic power generation pavement technologies are still in the conceptual and experimental stage, and there are many major defects in the pavement structure that do not meet the basic requirements of road engineering. It is easy to be permeable and the base layer is easy to be damaged, which leads to excessive deformation of the surface layer and other road engineering "common problems"; the cement concrete prefabricated panel technology in the Netherlands faces difficulties such as the difficulty of assembling large components on site and the lack of anti-skid ability of the tempered glass on the surface, so it is only used in bicycles. A small-scale test was carried out on the road; the French direct-buried technology lacks protection for the photovoltaic panel power generation layer, and it is very easy to damage the photovoltaic power generation layer under the action of vehicle load, which eventually leads to the loss of power generation capacity of the road surface

To sum up, no matter in terms of load-bearing tonnage or cumulative traffic load times, the current solar photovoltaic power generation road surface is still not a real road surface, so it cannot be applied to the actual road surface

[0007] On the other hand, my country and other countries use some facilities along the expressway to install photovoltaic panels to generate electricity. ), roadside slopes, etc. The photovoltaic panels laid on these facilities do not have the carrying capacity and are not laid on the road, so this kind of technology belongs to the photovoltaic power generation system of facilities along the line, and cannot use the vast road resources
