Sewage nozzle protection door device, skirt board and EMU

Abstract

The invention provides a sewage suction mouth protective door device, a skirting board and a motor train unit. The sewage suction mouth protective door device comprises a protective frame arranged on a skirting board window and a protective door for shielding an opening in the protective frame and is characterized in that the protective door is located on side of the protective frame, the protective door and the protective frame are matched through two parallelly-arranged chutes and two sliding rails in a sliding mode. Each sliding rail is arranged one corresponding chute. When the protective door is in an opening state, the outline width is not increased, and a whole train is prevented from going beyond the limitation bounds, so that the opened protective door is not bumped and damaged during train running, and potential safety hazard caused by the fact that the protective door bumps a platform is thoroughly eliminated. The protective door is located on the inner side of the skirting board, and even if a locking device is invalid, the protective door does not drop onto the outer side of a train body. The skirting board can be installed and welded in a blocking mode, and adjustment of a whole structure is facilitated.

Description

technical field [0001] The invention relates to rail vehicle technology, in particular to a protective door device for a sewage suction nozzle, an apron and an EMU. Background technique [0002] like Figure 1-4 As shown, the sewage suction nozzle 1a of the high-speed EMU is arranged on the toilet 10. After the train stops, the sewage suction nozzle 1a is connected with the sewage suction vehicle through a pipeline, and the dirt collected in the toilet collection 10 is discharged into the sewage suction vehicle. The lavatory 10 is connected with the toilet of the vehicle and the toilet drain, and is used to collect the waste water in the lavatory and the lavatory; the lavatory 10 is usually located at the bottom of the carriage, and is arranged across the width direction of the carriage; 1a is generally arranged at both ends of the toilet 10, and is located on both sides of the compartment; since the toilet 10 and the sewage suction nozzle 1a are located inside the compartme...

AI Technical Summary

Problems solved by technology

Once the protective door is in the open state when the train is running due to misoperation or lock failure, and the protective door exceeds the limit of the train, especially at platform 30, once the train with the protective door open enters the platform, the protective door 2 will be in contact with platform 30. Collision occurs, resulting in damage to the protective door 2 and even the car body
