Gas leakage detection device for natural gas pipeline transportation

Abstract

The invention discloses a gas leakage detection device for natural gas pipeline transportation. The gas leakage detection device comprises a transportation and detection trolley movably arranged on a natural gas pipeline, a working box body is arranged on the operation inspection trolley, a walking balance mechanism is arranged on the working box body, and walking rails are arranged at the joints of the two natural gas pipelines; the working box body is internally provided with a natural gas tank, the working box body is also internally provided with a gas leakage detection mechanism, the gas leakage detection mechanism is connected with the natural gas tank, and the natural gas pipeline transportation gas leakage detection device is different from the prior art, so that the walking balance mechanism is connected with the transportation and detection trolley; the operation and detection trolley is arranged on the natural gas pipeline, stable operation of the operation and detection trolley can be guaranteed, the situation that the operation and detection trolley deviates leftwards and rightwards is avoided, and when the operation and detection trolley operates on the natural gas pipeline, the gas leakage detection mechanism can conduct gas leakage detection work on the natural gas pipeline and conduct self-detection work on the gas leakage detection mechanism under timing exhaust of the natural gas tank.

Description

technical field [0001] The invention relates to the technical field of pipeline detection devices, in particular to a gas leakage detection device for natural gas pipeline transportation. Background technique [0002] Now the use of natural gas is gradually increasing, and pipelines are needed to transport natural gas. With the growth of use time, natural gas pipelines may leak, causing waste of resources, and may also cause fire or explosion. At present, there is no inspection device when the pipeline leaks, and inspectors need to inspect each section of the pipeline one by one. This detection method is time-consuming, inefficient, and requires more manpower to detect the pipeline. The fire or explosion caused by the leakage of the pipeline will endanger the life and health of the testing personnel, and this testing method is relatively dangerous. [0003] In order to solve the above problems, in the Chinese utility model patent with the publication number CN213452906U, a ...

Problems solved by technology

[0004] However, we have found in actual use that when the motor is started, the gears rotate accordingly, and the gears mesh with the teeth, which will drive the first slider to slide in the first chute, and the second slider to slide in the second chute. The box will also move accordingly. However, when it is in use, structures such as support frames, slide plates and racks need to be installed on the natural gas pipeline, resulting in higher initial costs and complicated installation. In addition, the setting of natural gas pipelines is mostly random. Therefore, there will be situations such as high and low tilts and turns at various angles, which will undoubtedly increase the installation design and installation steps of the support frame. Therefore, we propose a gas leakage detection device for natural gas pipelines
