the barrier main body 210 between the lower portion and the side portion of the barrier is used for receiving the liquid entering from the cover vent 110 and blocking the liquid from entering the side of the barrier main body 210 away from the cover.

The ventilation structure also comprises a cover plate and a blocking piece; the cover plate is provided with a cover plate ventilation opening, a blocking piece is arranged on one side of the cover plate, which faces the vehicle body, the lower part of the blocking piece and the cover plate are fixed under the cover plate ventilation opening in a sealing mode, and the side part of the blocking piece and the cover plate are fixed outside the side end of the cover plate ventilation opening in a sealing mode; the blocking piece main body between the lower part and the side part of the blocking piece is used for receiving liquid entering from the cover plate vent hole, and the liquid is blocked from entering one side, far away from the cover plate, of the blocking piece main body, so that the liquid is blocked from entering the vehicle body. The ventilation structure is additionally provided with a blocking part, the blocking part blocks liquid entering from the ventilation hole of the cover plate from entering one side of the blocking part far away from the cover plate, and then the liquid is blocked from entering the train body, so that the damage of the liquid entering the ventilation structure to equipment in the train is avoided.

The cover vent also functions to drain some of the liquid if the level of the liquid reaches the position of the cover vent as the liquid entering from the cover vent increases.

In practice, the barrier is waterproof to a level up to the international industry standard IPX 5.

In practice, as shown in fig. 7, the inner edge of the cover plate is provided with a waterproof sealing strip 120, and the waterproof grade of the waterproof sealing strip reaches the international industry waterproof grade standard IPX 5.

In practice, as shown in fig. 7, the barrier body 210 is recessed away from the cover plate 100, so that a receiving gap is formed between the barrier body 210 and the cover plate 100;

wherein the receiving gap is adapted to receive liquid entering from the cover vent 110.

The presence of the receiving gap indicates that the barrier body and the cover are not in close proximity, i.e. the ventilation structure is able to receive a quantity of liquid, which is also applicable when the environment outside the train in which the ventilation structure is installed is relatively liquid.

In order to discharge the liquid in the receiving space as quickly as possible, in an implementation, as shown in fig. 7, the cover plate further includes a liquid outlet 130, the position of the liquid outlet 130 is lower than that of the cover plate vent hole 110, and the lower portion of the blocking member is sealingly fixed with the cover plate below the liquid outlet 130, so that the liquid entering the receiving space is discharged from the liquid outlet.

In practice, as shown in fig. 1, the upper end of the ventilation structure is further provided with a top vent 300 communicating with the receiving gap, so that gas generated from the equipment in the vehicle body is exhausted through the blocking member vent hole 230 and the top vent 300.

The structure of the top vent can discharge gas generated by the equipment as much as possible, and is particularly beneficial to discharge gas with lower density, such as hydrogen.

In implementation, the blocking member vent hole is a long round hole arranged transversely;

or the blocking piece vent holes are arranged in a plurality, are arranged at equal intervals along the transverse direction and are long round holes.

In practice, as shown in fig. 6 and 7, the cover plate vent 110 is a plurality of and is a flip-in louver; or may be a tilt-out blind.

In practice, as shown in fig. 6, the liquid outlet 130 is a plurality of liquid outlets, and the positions of the liquid outlets are consistent in height, and the liquid outlets are oblong holes.
