Description

Technical Field

[0002] The problem of cooling railway tracks usually refers to taking various measures to reduce the temperature of the tracks to prevent deformation and damage caused by high temperatures. In high temperature seasons, the railway department may take measures such as sprinkling water for cooling and shading and covering. In low temperature seasons, heating or other measures may be required to prevent cracks in the tracks due to cold contraction. These measures ensure the safety and stability of railway lines, but specific cooling methods and techniques may vary from region to region and specific circumstances, and need to be determined in combination with actual conditions and technical conditions. When the temperature of railway rails is too high under sunlight, they need to be cooled. The current practice is to lay straw ropes at the waist of the rails and manually pour cold water on the straw ropes to cool them down. The disadvantage of this method is that it is labor-intensive and the continuous cooling effect is not good enough.

[0003] After searching, in the related technology, the patent document with authorization publication number CN201908242U discloses an automatic rail cooling device, which is composed of a thermometer, an electromagnet and a sprayer. One end of the electromagnet coil is connected to the low-end mercury of the thermometer through a battery power supply, and the other end of the electromagnet coil is connected to a metal wire extending in the thermometer at a set water spray temperature. The contact electrode of the electromagnet is connected to the power circuit of the sprayer. The advantage is that it can automatically detect the temperature of the rail and cool the rail in time.
