The existing stainless steel railway vehicle has two roof structures, the first is a high arc roof structure, and because of the requirement of vehicle limit, the limit should be met after the air conditioner is installed, so the air conditioner flat tops arranged on the high arc roof structure are all sinking type air conditioner flat tops. The second type is a short arc top roof structure, and the air conditioner can be directly fixed on the roof through a mounting seat due to the short height of the short arc top roof structure, so that the air conditioner flat tops arranged on the short arc top roof structure are mostly straddle type air conditioner mounting structures.
The existing air conditioner flat top structure is mostly of a sinking type, a structure with a filter screen water outlet, a water drainage tank, an end top and the like is arranged on the air conditioner flat top, and the filter screen is installed at the opening of the water drainage tank through screws. When the rain weather is met, rainwater can flow into the drainage groove through the meshes of the filter screen, and then the rainwater is drained to the lower part of the vehicle through the drainage groove. Because the air conditioner flat top belongs to the welded structure, certain deformation can be caused inevitably, meanwhile, because the air conditioner flat top belongs to the exposed part, the phenomenon of sundries accumulation can be avoided inevitably, the welding deformation easily causes the air conditioner flat top flatness to be poor (concave), the existing air conditioner flat top filter screen is a flat plate type, and is flush with the top plate of the air conditioner flat top after being installed, so that the air conditioner flat top filter screen is easily blocked by sundries such as leaves and the like. When the air conditioner flat top is sunken or the filter screen is blocked, the air conditioner flat top can generate water accumulation, and when the water accumulation exceeds a certain depth, rainwater can be caused to enter the vehicle along the position of the sealing rubber strip, so that the phenomenon is absolutely not allowed. Meanwhile, the filter screen is directly fixed on the drainage groove through the screw, the drainage groove is manufactured by adopting a cold drawing process, and meanwhile, in order to meet the requirement of weight reduction of the vehicle body, a thick plate cannot be used, so that the screw is effectively screwed less, and the risk of loosening and falling of the screw is possibly caused.
