RAIL TRAIN
Document Type and Number:
WIPO Patent Application WO/2020/119043
Kind Code:
A1
Abstract:
A rail train, comprising: compartments (10), mounting ports (11) being provided on side portions of the compartments (10), and devices for generating a gas being fixed, in the compartments (10), at positions behind the mounting ports (11); and ventilation structures mounted at the mounting ports (11). Each ventilation structure comprises a cover plate (100) and a stop member (200). The cover plate (100) has a cover plate ventilation hole (110). The stop member (200) is provided on the side of the cover plate (100) facing the body of the compartment. The lower portion of the stop member (200) and the cover plate (100) are sealably fixed below the cover plate ventilation hole (110). The side portion of the stop member (200) and the cover plate (100) are sealably fixed outside a side end of the cover plate ventilation hole (110). A stop member body (210) between the lower portion and the side portion of the stop member (200) is used for receiving a liquid entering from the cover plate ventilation hole (110) and stopping the liquid from entering the side of the stop member body (210) away from the cover plate (100), thereby stopping the liquid from entering the body of the compartment (10). The rail train resolves the technical problem of damages to devices in a rail train due to the entrance of a liquid outside the train into the train caused by the ventilation of the train.
