Condensed water drainage tank structure and floor for rail passenger car

Abstract

The invention discloses a condensate water drainage channel structure and a floor for a railway passenger vehicle. A drainage channel is of an arch structure with the middle higher than the two ends in the length direction. Two vertical faces of the drainage channel are each provided with a plurality of drainage holes, the drainage holes in the two vertical faces are symmetrical with respect to the width central line of the drainage channel, and the drainage holes in each vertical face are symmetrical with respect to the length central line of the drainage channel. According to the condensate water drainage channel structure, condensate water located in wave troughs can be conveniently guided into the drainage channel and then drained outside the vehicle. The condensate water in the wave troughs flows into the drainage channel through the long round holes in the vertical faces of the drainage channel firstly, and since the middle of the bottom face of the drainage channel is higher than the two ends of the drainage channel, the condensate water flows to the two sides and flows out through a drainage pipe; and if the drainage pipe is blocked and not dredged in time, the condensate water is stored in the drainage channel since the bottom face of the drainage channel is lower than the wave troughs, and the stainless steel drainage channel is good in corrosion resistance.

Description

technical field [0001] The invention relates to the technical field of rail vehicle floor drainage, in particular to a condensed water drainage groove structure and a floor for rail passenger cars. Background technique [0002] The floor of the carbon steel car body chassis of existing rail cars adopts corrugated floor inside the pillow and flat floor outside the pillow, and the material is Q310NQL2. The existing condensate drainage scheme is to open drainage holes in each trough of the corrugated floor 3m away from the pillow center, with a diameter of Φ8mm, and two holes are opened in each trough along the length of the vehicle; Two drainage holes, two on each side, with a diameter of Φ6mm. The location of the drainage holes should avoid the under-vehicle equipment, and can be adjusted according to the under-vehicle equipment. [0003] According to feedback from vehicle operation, the drainage holes are often blocked by dust, and the iron floor is severely corroded. Exis...

Problems solved by technology

[0005] 2) When spraying anti-corrosion paint on the bottom frame, it is necessary to protect the drainage holes, which increases the difficulty and workload of the work. Improper protection may block the drainage holes. In the later stage, special personnel are required to check and clear them, and the workload is heavy;

[0006] 3) After the vehicle has been used for a period of time, the drain hole is easy to block, if it is not cleaned in time, the condensed water will accumulate on the iron floor and cause corrosion
