Abstract

The invention provides a water filling nozzle protection device of a motor train unit and a motor train unit train body. The water filling nozzle protection device of the motor train unit comprises a fixing board and a cover plate assembly, the top end of the fixing board is fixedly connected with a train chassis, the bottom end of the fixing board is fixedly connected with an equipment compartment bottom board, an installation through hole for fixing a water filling nozzle is opened on the fixing board, and two sides of the fixing board form sealing turned edges respectively; the cover plate assembly comprises a protection cover plate and a vertical plate, the cover plate assembly is snapped on the fixing board and jointly defines a hollow accommodating cavity with the fixing board, the hollow accommodating cavity is used for accommodating and sealing the water filling nozzle, a sealing bar is fixedly arranged at the edge of the vertical plate, and the vertical plate is propped at the sealing turned edges of the corresponding fixing board. According to the water filling nozzle protection device of the motor train unit and the motor train unit train body, by means of the arrangement of the sealing bar on the cover plate assembly and the arrangement of the cover plate which is adaptive to the arc shape of an equipment compartment apron board, convenient operation of water filling is achieved, tight locking of the cover plate is guaranteed, the maintenance is convenient, and installation space of the device is saved.

Description

technical field [0001] The invention relates to the manufacturing technology of railway vehicle components, in particular to a protective device for a water injection port of an EMU and a car body of an EMU. Background technique [0002] The EMU water injection port is used to deliver tap water that meets the hygienic standards to the EMU water storage tank. Generally speaking, each carriage is equipped with two water injection ports, which are located under the car and in the equipment compartment on both sides of the car body. To ensure the quality of the water in the water tank, the water injection port needs to be sealed in a relatively closed space with a protective cover. [0003] In the prior art, the protective cover of the water injection port is installed on the skirt of the equipment cabin in an outward-turned manner. When the train is running, it is locked by four-corner locks, and when water is injected, it is turned outwards to open. [0004] This type of prot...
