Self-radiating device of internal combustion locomotive power room

Abstract

The invention discloses a self-radiating device of an internal combustion locomotive power room. The self-radiating device is mainly composed of a top cover protection plate, an air dividing assembly and a bottom decorative plate. The top cover protection plate is composed of a perforated flat plate and a steel wire mesh. The air dividing assembly is composed of dividing plates, wind shields, connecting beams and drainage pipes jointly. The lower ends of the dividing plates are bent into semi-circles so as to prevent rainwater, dust and the like from falling into the power room, and the influence of air turbulent flows on the air speed of exhaust air can be further prevented through the semi-circles. The two edges of the dividing plates are welded to the connecting beams, and thus an overall frame is formed; and the overall frame is welded to the drainage pipes in a butt joint mode, and thus a drainage system is formed. The wind shields are located in the front of the device and welded to the ends of the connecting beams; air is pushed to flow rapidly through the inclined angle of the wind shields; and a vacuum is formed at the top of the device, so that hot air in the power room is prompted to rise to be discharged. The air convection principle is fully utilized, no driving power is needed, the load output of a diesel engine is reduced, and the management cost and the maintenance cost are also reduced.

Description

technical field [0001] The invention relates to the technical field of diesel locomotive power devices. Background technique [0002] The diesel generator set in the power room of a diesel locomotive will generate a large amount of heat energy radiation. Although the cooling system of the diesel engine takes away most of the heat from the cylinder, supercharger and other components, the heat dissipation of the engine body and other components still makes the temperature of the power room very high. . High temperature not only makes the working environment of personnel worse, but also leads to accelerated aging of electrical components and electrical circuits, and reduces the mechanical properties of components. [0003] Existing internal-combustion locomotive is designed to solve this problem, and car body ventilating unit is generally installed additionally. The ventilation unit generates positive or negative pressure in the air in the power room of the locomotive through...

AI Technical Summary

Problems solved by technology

[0006] 1. The ventilation unit needs to be driven by motors with different powers according to the exhaust air volume, which not only increases the power consumption of the main generator, but also increases the power consumption due to the influence of the failure rate of the motor itself, the connection accuracy of the motor and the impeller, and the strength of the impeller. The overall failure point of the locomotive

[0007] 2. In the prior art, even if the stepless speed regulation method is adopted, the speed of the fan can be continuously changed, but because the speed regulation signal can only be the speed of the diesel engine, the exhaust air volume cannot be determined according to the thermal effect, so it is not suitable exhaust hot air

[0009] 4. Maintenance and overhaul requires more labor and management costs
