Problems solved by technology

[0007] The disadvantage of the first solution is that it requires a lot of power consumption, and the melted snow water is difficult to evaporate, which is easy to cause freezing damage to the roadbed of the line, and the permafrost area will also affect the environment.
The second solution uses an electromagnetic induction heater, which essentially melts ice and snow by heating. Although it can reduce part of the energy consumption, the heater needs to be closely attached to the rail waist, which is likely to affect the line operation of the public works
The third solution uses centralized compressors and storage tanks, which eliminates the dependence on heating and snow removal methods. However, due to the need to set up compressor units, storage tanks and complex air pressure pipelines, the installation and construction are complicated, which is not conducive to large-scale practical applications.

Abstract

The present disclosure provides a device that prevents snow from freezing on turnouts by means of airflow , comprising: an air nozzle configured to blow away ice, snow, or water at a gap between a sharp rail and a base rail; an air nozzle configured to blow away ice, snow, or water at a gap between the sharp rail and the base rail; A perforated leakage air duct arranged on the outer side of the point rail action area for generating an air flow barrier, the direction of the air flow barrier being toward the outer side of the track line; And an air pump for delivering gas to the nozzle and the perforated leakage duct.

Description

technical field [0001] The present disclosure relates to the technical field of railways, in particular to a device for preventing snow accumulation and freezing of a turnout by means of air flow. Background technique [0002] The turnout is composed of a fixed basic rail, a movable switch rail, a sliding bed plate supporting the switch rail, and a movable core rail. The switch rail can slide on the sliding bed under the traction of the switch conversion equipment. When the switch rail on one side slides to the basic rail on the same side, the switch rail on the other side is separated from the basic rail on the same side, and the line opens in one direction; The switch rail slides in the other direction under the traction of the switch conversion equipment, and when the switch rail on the other side slides until it is in close contact with the basic rail on the same side, the switch rail on this side is separated from the basic rail on the same side, and the line opens in a...
