[0002] During use, rails are subject to various environmental influences and wear and tear from trains, which can cause damage to the tracks and lead to accidents. To eliminate these hazards, inspectors need to inspect the tracks. Currently, my country primarily uses ultrasonic equipment for track inspection, with portable rail flaw detection equipment being the most popular. This equipment utilizes a built-in ultrasonic generator on a vehicle that can move along the track, making it a more convenient ultrasonic inspection device for track use. Existing water system technology for portable rail flaw detection equipment has the following issues: 1) Due to space limitations within the flaw detection vehicle, the water tank capacity is small; 2) Water from the water tank drips uncontrollably onto the rails, resulting in uneven distribution of water along the track and affecting inspection accuracy; 3) Excessive water addition results in water waste, impacting the inspection distance.
