Abstract

The invention discloses a power chamber sealing structure of a dual-fuel locomotive. The power chamber sealing structure comprises a power chamber and an engine arranged in the power chamber, wherein the power chamber is used for sealing a space above the engine to form a sealed chamber; a locomotive body ventilator is arranged on a top cover of the power chamber and is communicated with the inner part of the sealed chamber; an air inlet gap is formed in the bottom of the sealed chamber. The power chamber sealing structure of the dual-fuel locomotive has the beneficial effects that liquefied natural gas which is likely to leak is effectively isolated in the sealed chamber and is pumped out of the power chamber in time, so that accidents can be prevented from occurring; and the safety is high.

Description

technical field [0001] The invention relates to the technical field of locomotives, in particular to a closed structure for a power chamber of a dual-fuel locomotive. Background technique [0002] Usually, the diesel locomotive engine is installed in the power room, and is exposed in the power room, so as to facilitate the maintenance of the engine. However, there is a hidden danger in the use of dual-fuel engines: once the liquefied natural gas pipe entering the upper part of the engine leaks, the leaked natural gas will become a flammable and explosive hazard in the power room, while ordinary diesel engines have no this problem. Therefore, it is necessary to improve the structure of the power room to improve safety and eliminate hidden dangers. Contents of the invention [0003] The object of the present invention is to provide a closed structure for the power chamber of a dual-fuel locomotive in view of the above existing problems. [0004] The technical scheme that ...
