Ventilation device of electrical transmission steel rail grinding vehicle, system and method thereof

Abstract

The invention discloses a ventilation device of an electrical transmission steel rail grinding vehicle, a system and a method thereof; the device comprises an inertial filter and a blind window; the inertial filter comprises a dust collection tank, a dust removing fan, a dust removing port and a dust removing air duct; the blind window comprises a V-shaped groove and louvre blades; the louvre blades are arranged on both sides of the V-shaped groove; the bottom of the V-shaped groove is provided with the dust collection tank; when a ventilator in a vehicle body works, negative pressure is formed in the vehicle body, external air enters through a relative front end of the V-shaped groove of the blind window, impurities pass through the dust collection tank at the relative bottom of the V-shaped groove under the inertial action and are discharged out of the dust removing port through the dust removing fan in the dust removing air duct, the filtered air enters the vehicle body through the louvre blades of the blind window, and the air and the impurities are separated. Two devices are arranged over against each other on the side wall of the vehicle body to form the system. According to the ventilation device of the electrical transmission steel rail grinding vehicle, the system and the method thereof, the technical problems in the prior art that the air cleanliness in the vehicle body and the radiating requirements on electrical equipment cannot be met, the working conditions in the vehicle body for personnel are quite poor are solved.

Description

technical field [0001] The invention relates to a ventilation device, a system and a method thereof applied in the field of railway engineering, in particular to a ventilation device, a system and a method thereof applied to a large-scale track engineering road maintenance vehicle-electric drive rail grinding vehicle. Background technique [0002] Existing rail grinding vehicles use diesel engines to provide power and power supply. In addition, the working environment is harsh, and a large amount of dust is produced during the operation process, resulting in a very poor working environment inside the car body. The existing rail grinding car adopts a natural ventilation method in which shutters are only arranged on both sides of the car body, which has very limited effects on cooling ventilation and dust removal. The ventilation device is generally mainly composed of a fan, an air intake and exhaust duct and an air filter device. [0003] On the electric transmission locomot...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to provide a ventilation device, system and method for an electric drive rail grinding car, which solves the problem that the existing ventilation device, system and method cannot guarantee the cleanliness of the air inside the car body, and cannot Meet the heat dissipation requirements of the electrical equipment in the electric drive grinding car, and the technical problem of poor working environment inside the car body where the electric drive system is installed
