Description

HXD3CA type electric locomotive fan wind speed monitoring device Technical Field The application relates to the field of locomotive maintenance and monitoring, in particular to a HXD3CA type electric locomotive fan wind speed monitoring device. Background The HXD3CA type electric locomotive is one of main locomotive types for railway trunk freight, and the stable operation of a composite cooling system is crucial to a power system of the locomotive. The fan of the composite cooler is responsible for forced air cooling of cooling medium, if the fan fails or efficiency is reduced, the main converter and the main transformer can be overheated, and an accident of machine breaking can be caused when serious, so that driving safety is influenced. Currently, daily monitoring of locomotive wind speed is primarily dependent on hand-held anemometers. However, the HXD3CA type locomotive composite cooler air duct, especially the air duct positioned in the locomotive and at the bottom of the locomotive, has compact position design, hidden structure, extremely narrow space and is often shielded by surrounding pipelines and a car body structure. This results in conventional wind speed monitoring devices and manual hand-held measurements at least facing the following significant difficulties: (1) The accessibility is poor, a measurer is difficult to directly enter or get close to an air duct outlet, especially the position of an air duct at the bottom of a vehicle is drilled, and a conventional anemometer probe cannot stably extend into or be aligned. (2) The operation is unsafe, the maintenance personnel often need to twist or bend down in the trench at the bottom of the vehicle, the posture is unstable, and the safety risks such as collision, slipping and the like exist. Meanwhile, the fan is in a load state during measurement, and the risk of discharge damage of the fan exists. (3) The reading error is large, the anemometer screen is difficult to observe due to space limitation and insufficient light, reading errors are easy to cause, the probe is easy to shake when the anemometer is held for measurement, the probe is difficult to be vertical to the wind direction, and the measurement accuracy is difficult to be influenced. Therefore, in the daily maintenance and status monitoring of locomotives, a wind speed monitoring method which can adapt to narrow and concealed spaces and is convenient for remote operation and reading is urgently needed, so as to improve the measurement efficiency, the data reliability and the operation safety.
