Problems solved by technology

[0006] In addition, the battery car using hydrogen fuel currently under development has a hydrogen pressure of 300mba to 350mba, which is a high pressure, and the diffusion rate of hydrogen is 6 times that of natural gas and 2.7 times that of helium (helium). It is difficult to detect, but it can be easily detected when it is detected in a closed casing

Abstract

Disclosed is a pressure-resistant-container gas leakage detecting device for a vehicle to which a discharge tube casing is attached. The pressure-resistant-container gas leakage detecting device for a vehicle which is provided comprises: a casing comprising a first casing member, and a second casing member that is coupled to the first casing member so as to form an internal space; a pressure-resistant container to which is coupled a body part inside the casing, and which is formed so as to have a discharge tube that allows gas to be injected from and discharged to the outside; a discharge-tube casing for covering the discharge tube; a first gas leak detecting sensor attached to the discharge-tube casing; a corrosion-preventing gas which is injected between the pressure-resistant container and the casing, and is filled so as to be higher or lower than atmospheric pressure; and a gas pressure detecting sensor which is coupled to the casing, and detects when a change occurs in the pressure of the corrosion-preventing gas.

Description

technical field [0001] The present invention relates to a gas leakage detection device for a pressure-resistant container used in a vehicle combined with a discharge pipe casing using a gas leakage detection device, which is used in the presence of a trace amount of gas in order to prevent gas leakage and explosion accidents. In the event of leakage, gas leakage can also be detected early in the early stage. Background technique [0002] The introduction of compressed natural gas (CNG) buses (hereinafter referred to as natural gas vehicles) for the purpose of environmental protection is gradually increasing, but the biggest problem with natural gas vehicles is safety. In August 2010, a natural gas vehicle in operation was The pressure vessel exploded, causing a large fatal accident. [0003] The pressure-resistant container is attached to the upper and lower parts of the vehicle. Since the lower part of the vehicle is exposed to impurities, chemicals and rainwater on the ro...
