Gas pipeline leakage detection device and application method thereof

Abstract

The invention discloses a gas pipeline leakage detection device and an application method thereof, and in particular relates to the field of gas pipeline leakage detection. The detection device is arranged in a gas pipeline movably. The detection device comprises an annular housing, a plurality of detection assemblies and a plurality of driving mechanisms. The detection assemblies are uniformly arranged on the inner side wall of the annular housing in a surrounding manner, the driving mechanisms are uniformly arranged on the outer side wall of the annular housing in a surrounding manner and are attached to the inner wall of the gas pipeline, and the detection device is separately driven by gas conveying wind power and the driving mechanisms to move linearly in a reciprocating manner in thegas pipeline and detects the gas pipeline in the reciprocating motion process all around. The detection device detects a leakage condition by means of a plurality of groups of sensor probes accordingto pressure or flow. Matched with an angular sensor and a GPS positioner in use, the gas pipeline leakage detection device can find a gas pipeline leakage position quickly and precisely, so that workof exacting the leakage position again by maintenance staff in a later period is avoided. Quick repair can be further achieved, so that soil pollution is avoided.

Description

technical field

[0001] The embodiments of the present invention relate to the field of gas pipeline leakage detection, in particular to a gas pipeline leakage detection device and a method for using the same. Background technique

[0002] The gas content in the soil of the earth has a great influence on the growth of vegetation. At present, the urban greening area is mainly the street greening location. According to the requirements of the greening and environmental protection unit, the soil and soil gas content of the greening vegetation death were studied, and the cause of some vegetation death was found. It is closely related to methane, which is the main component of city gas. Leaked gas is mixed in soil gas through turbulence, mass flow, etc. in the process of urban gas transmission (relying on soil respiration takes several months to remove methane), causing local vegetation to die due to lack of oxygen. Conduct research on the problem of preventing gas leaks. [000...
