Abstract

The invention relates to a road heating device which comprises a heating assembly and an isolation hood, the heating assembly is suitable for heating a preset road surface, the isolation hood is arranged on the periphery of the heating assembly, and a sealing strip is arranged at the end, making contact with the preset road surface, of the isolation hood. According to the invention, a specific road surface can be heated and the temperature can be controlled through the movable road heating device, a temperature environment for piezoelectric material polarization on a road site is realized, and the condition limitation that piezoelectric ceramic polarization can only be completed in a laboratory or a factory in the prior art is solved. The invention also relates to an on-site air polarization system and an on-site air polarization method for the road piezoelectric energy collector.

Description

technical field [0001] The invention relates to the technical field of polarization of piezoelectric ceramic materials, in particular to an on-site polarization system and method of road piezoelectric energy collectors. Background technique [0002] Piezoelectric ceramics are a class of ceramic materials with piezoelectric properties, which can realize the conversion between mechanical energy and electrical energy. Piezoelectric ceramic materials have been widely used in many fields, but they are rarely involved in the field of road engineering. Considering that the road surface is subjected to repeated loads from cars every day, the energy generated by it is immeasurable. If it can be used Power generation will inevitably produce good economic and environmental benefits. Road piezoelectric energy harvesting, as a green energy utilization technology that converts renewable resources into electric energy, has broad application prospects and low-carbon significance, and confo...

AI Technical Summary

Problems solved by technology

[0003] The fatigue degradation of the piezoelectric collector under long-term traffic load will affect the energy conversion efficiency. After the piezoelectric collector reaches the designed service life, the PZT piezoelectric ceramics in the collector will depolarize and break. Electric collectors are cost prohibitive and can also damage pavement integrity

The disadvantage is that the existing technology can only complete the polarization of piezoelectric ceramics in the laboratory or factory, and there is a lack of technology and related equipment for the polarization of piezoelectric materials on the road.
