Description

Technical Field

[0001] The utility model belongs to the field of patrol inspection technology and relates to a gas parameter patrol inspection device for a gas transmission pipeline with muddy water protection. Background Art

[0002] The gas parameters in the existing gas transmission pipelines are mainly tested by manual testing and automatic monitoring devices. For the testing of gas parameters in ultra-large-scale gas transmission pipelines, the manual testing cycle is long and the workload is large. For example, the coal seams in mines contain more moisture, and the muddy water generated by drilling and sealing and the residual coal slag in the boreholes are not easy to completely remove. The sensors of general automatic monitoring devices are easily blocked and interfered by impurities such as muddy water in the pipeline, resulting in low efficiency of pipeline transmission gas parameter testing, inability to effectively collect data, and even data distortion.

[0003] The invention patent application document with publication number CN104832157A discloses a coal seam drilling gas parameter detection-based outburst prediction device, including a collection tube, the collection tube is connected to one end of a hose, the other end of the hose is connected to the air inlet of the air chamber through a filter device, a sensor is arranged in the air chamber; the sensor is connected to a processing circuit; the processing circuit is connected to a display screen; the air outlet of the air chamber is connected to an outlet pipe; an explosion-proof solenoid valve is arranged on the outlet pipe; an exhaust hole is arranged at the end of the outlet pipe. The coal seam drilling gas detection device in the comparative document can simultaneously measure the gas concentration, gas flow, gas temperature and gas pressure in the coal seam borehole, and the data can be displayed in real time, continuously recorded and easily queried; underground coal mine engineering and technical personnel can timely and accurately grasp the degree of outburst danger at the measurement location, and can provide technical support for the safe and economical mining of outburst coal seams. However, the comparative document is for a prediction and forecasting device that reflects the danger of coal and gas outbursts and displays the results in real time. It is not applicable to the testing of gas parameters in ultra-large-scale gas transmission pipelines. At the same time, the technical solution of the comparative document for gas parameter detection containing mud and water cannot be implemented, which will cause blockage of the detection pipeline and lead to low efficiency of gas parameter testing.
