Equipment compartment dust removal and ventilation device for transport machine

Abstract

The invention discloses an equipment compartment dust removal and ventilation device for a transport machine. The equipment compartment dust removal and ventilation device comprises a baffle frame assembly and a filter net assembly. The baffle frame assembly comprises an inner frame and a mounting plate. A middle lower guide plate, an air inflow lower guide plate and an air outflow lower guide plate are arranged in the inner frame. The inner frame is divided into two ventilation regions through the middle lower guide plate, one ventilation region is an air inflow region, and the other ventilation region is an air outflow region. A middle upper guide plate, an air inflow upper guide plate and an air outflow upper guide plate are fixedly mounted above the middle lower guide plate, the air inflow lower guide plate and the air outflow lower guide plate separately. The filter net assembly comprises a filter net frame and a wave-shaped filter net. By means of strong reverse airflow generated at the position of an air inlet of a skirt board when a bullet train unit runs, floating objects and air inflow airflow are voluntarily separated, and the separated floating objects are exhausted back to the atmosphere under coercing of airflow of a main ventilation duct; and meanwhile, under the effect of the guide surfaces of the guide plates, the air pressure at the position of the filter net is increased, a high-pressure region is formed, and active air supply to an equipment compartment is achieved.

Description

technical field [0001] The invention belongs to the technical field of dust removal for transportation vehicles, and in particular relates to a dust removal ventilation device for an equipment compartment of a transportation vehicle. Background technique [0002] In today's society, rail transportation mainly includes diesel locomotives, electric locomotives, EMUs, high-speed rail, passenger and truck carriages, light rails, subways and other transportation carriers, and road transportation mainly includes automobiles. Their normal operation needs to inhale a large amount of air to meet the needs of combustion of internal combustion engines, heat dissipation of electronic and mechanical components, and cooling of air conditioners and other facilities. With the inhalation of a large amount of air, there are a large number of floating objects such as dust, catkins, plant leaves, paper scraps, plastics, etc. in the air, which are adsorbed on the dust-proof devices of various ai...

Problems solved by technology

[0007] The blockage of the ventilation device has brought a lot of workload to the EMU. When the high-speed rail EMU returns to the station, it must check and clean the skirt filter, filter cotton, heat sink and other dust-proof and heat-dissipating equipment; it not only consumes a lot of manpower of the railway, Material and financial resources, and reduce the operating efficiency of high-speed rail EMUs

[0008] There are personal and driving safety hazards at the same time: 1) because the above-mentioned operations will be completed within a few hours after zero o'clock, the time is tight, the workload is large, the working environment
