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

Embodiment Construction

[0032] see figure 1 In this embodiment, the structure of the ice and snow melting bridge deck electric heating system with scanning cycle power supply is set as follows: the bridge deck ice and snow melting electric heating system is divided into independent and controllable parallel electric heating units according to the power load capacity, and each electric heating unit is along the direction of vehicle travel. Arrange in parallel at a set interval to form a longitudinal array, and control the grouping of each electric heating unit in the longitudinal array to work in a set time sequence cycle in the form of scanning.

[0033] In the specific implementation, each electric heating unit is marked as L1, L2...Ln in sequence of natural numbers from one side of the longitudinal array to the other side; said n is the number of electric heating units in the longitudinal array; the n electric heating units are divided into s Electric heating unit groups, and each electric heating ...

Abstract

The invention discloses a scanning type circulating power supply snow and ice melting bridge deck electric heating system. The snow and ice melting bridge deck electric heating system is divided into independent controllable parallel electric heating units according to electric load capacities; the electric heating units are arranged in parallel in the form of a longitudinal array according to a set distance; and the electric heating units in the longitudinal array are controlled in groups to work in circulation in the form of scanning according to a set time sequence. According to the invention, available electric power of a power supply system can be sufficiently utilized and the total power of the electric heating system is ensured; the heating uniformity is improved and secondary icing of melted water is avoided; the reliability of a snow and ice melting system is improved and convenience is brought to the maintenance; the scanning type circulating power supply snow and ice melting bridge deck electric heating system can be widely applied to various special road sections including airport runways, tunnel entrance transitional areas and the like so that the electric heating snow and ice melting method is 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...
