A scanning cycle power supply electric heating system for melting ice and snow bridge deck

Abstract

The invention discloses a scanning type circularly-powered electric heating system for melting ice and snow on a bridge surface. The electric heating system for melting ice and snow on the bridge surface is partitioned into independently-controllable electric heating units which are connected in parallel according to the power load capacity, wherein the electric heating units are distributed in parallel along the running direction of a vehicle at set intervals in the form of a longitudinal array; each electric heating unit in the longitudinal array is controlled to work circularly in different groups according to a set time sequence in a scanning form. By adopting the electric heating system, a power supply system can be used for supplying power, and the total power of the electric heating system is ensured; the heating uniformity is improved, and molten water is prevented from re-icing; the reliability of an ice and snow melting system is improved, and convenience is brought to maintenance; the electric heating system can be widely applied to various special road segments, including airport runways, tunnel inlet transition areas and the like, and a method for melting snow and ice by electrically melting can be well applied.

Description

[0001] The application number is 2014100786160; the application date is March 5, 2014, and the title of the invention is: an electric heating system for ice and snow melting bridge deck with scanning cycle power supply. The applicant is a divisional application of Hefei University of Technology. technical field [0002] The invention relates to an electric heating system for melting ice and snow on bridge decks, which is an electric heating system for melting snow and ice on occasions such as bridge decks, road surfaces or airport pavements. Background technique [0003] At present, the commonly used methods of melting snow and ice on pavement at home and abroad mainly include clearing method and melting method. The removal method is a manual removal method and a mechanical removal method; the melting method includes a chemical melting method and a thermal melting method; a new road surface material deicing method (adding a salt compound self-release method, adding a conducti...

Problems solved by technology

However, the construction of related equipment, as well as the post-operation and maintenance process require a lot of funds in advance, and the bridge deck or road surface snow melting and ice melting system is basically idle in seasons other than winter. For grade roads in the wild, When the distance from industrial electricity, toll stations, and service areas is far away, the power consumption will be more stretched, which seriously inhibits or even prevents the popularization and application of electric heating for snow melting and ice melting
