Abstract

The invention relates to the field of train operation safety, and discloses a train scale-imitating overturn-preventing structure so as to ensure the safety of train operation. The structure comprisesa base, a mounting hole, a support frame, a rotating shaft, scales, a micro motor, a control box and a wind speed detection device; a mounting hole fixed with a vehicle body is formed in the base; the support frame is arranged at one end of the base; the rotating shaft is arranged in the lower end of the support frame; a rotating frame is fixedly connected with the support frame; the scales are fixed on the support frame; a wind direction detection device is arranged on the windward sides of the scales; the micro motor is used for driving the rotating shaft to rotate; the micro motor and thewind speed detection device are respectively connected with the control box; and the control box is used for obtaining the wind speed and the wind direction angle in the train advancing process through the wind speed detection device, evaluating the risk grade according to the wind speed and the wind direction angle, calculating the scale opening angle enabling the overturning moment to be minimumwhen the risk exists through evaluation, and instructing the micro motor to drive the scales to reach the scale opening angle enabling the overturning moment to be minimum through the rotating shaft.

Description

technical field [0001] The invention relates to the field of train operation safety, in particular to a train imitation fish scale anti-overturning structure. Background technique [0002] The environment along my country's railways is complex and the climate is changeable, which has a significant impact on the aerodynamic performance of trains. In particular, strong winds exist in coastal areas and some flat inland areas, causing trains to stop running, and even causing train derailment, overturning and casualties, seriously affecting the safety of train operation and transportation efficiency. In order to ensure the safe operation of trains under severe wind conditions, the existing preventive measures include: implementing speed limits or stopping wheels, designing reasonable train shapes, setting up windshield walls, and establishing strong wind warning systems, etc. Among the above-mentioned measures, the establishment of a strong wind warning system and the implementa...
