Photovoltaic pavement system

Abstract

The invention discloses a photovoltaic pavement system. The photovoltaic pavement system comprises a general control unit, a roadbed, a photovoltaic pavement and drainage troughs on both sides of thephotovoltaic pavement. The photovoltaic pavement comprises a plurality of photovoltaic panel modules. The photovoltaic pavement system is characterized in that the roadbed is provided with a support part, the support part is used for supporting the photovoltaic module, a water collecting channel is formed between the roadbed and the support part, a water collecting tank is provided with water collection tanks at intervals, the support part is paved with the photovoltaic panel modules, a circulating water pipe is disposed between the photovoltaic panel module and the support part, a heat collector is arranged at the water collecting tank, and the circulating water pipe is communicated with the heat collector through a first water pump. The photovoltaic pavement system realizes cooling of the photovoltaic pavement in the hot weather, and melting of the snow and the ice layer on the photovoltaic pavement in the cold weather. The support part transforms the bending moment stress generatedby the load on the photovoltaic panel module into compressive stress or transforms the most of the bending moment stress into compressive stress and prolongs the service life of the photovoltaic panelmodule and the service life of the whole photovoltaic pavement.

Description

technical field [0001] The invention relates to traffic pavements, in particular to a photovoltaic pavement system, which is mainly applicable to the pavement application of expressways. Background technique [0002] The concept of photovoltaic roads first appeared in 2006. In 2013, the Bruces of Idaho, USA, developed a hexagonal solar slab shaped like a brick with a concave-convex surface. On a cement concrete base. In addition to its unproven load-carrying and road performance, this structure is expensive and requires a lot of labor. Therefore, so far, only a 15-square-meter open-air structure has been built in Sandpoint, Idaho, USA. PARKING LOT. [0003] In November 2014, a 230-foot-long (about 70 meters) solar bicycle road was officially opened in a town called Cromeny in the Netherlands. The road is made of 2.4m x 3.3m prefabricated cement concrete slabs, and the solar cells are placed under layers of tempered glass. [0004] The French company COLAS used the direct...

AI Technical Summary

Problems solved by technology

[0006] The above-mentioned four 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. The base layer was destroyed, which led to problems such as excessive deformation of the surface layer; the cement concrete prefabrication technology in the Netherlands faced difficulties such as on-site assembly of large components and insufficient anti-skid ability of the tempered glass on the surface, so only small-scale tests were carried out on bicycle lanes; The 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 loads, which eventually leads to the loss of power generation capacity of the road surface; although the photovoltaic experimental road section opened in Jinan, Shandong Province can carry small cars and medium-sized trucks And melt the snow on the road, but the hot weather can not cool the road, which leads to a greatly shortened service life of photovoltaic roads
