Abstract

The invention relates to the technical field of gas detection, in particular to a toxic gas in-situ detection device for drainage pipeline detection equipment, wherein a waterproof cover supported by a strut is arranged on the top side of a box body of the pipeline detection equipment; a combustible gas sensor socket and a hydrogen sulfide sensor socket are arranged on the top side of the box body of the pipeline detection equipment and in the covering scope of the waterproof cover; the signals of a combustible gas sensor and a hydrogen sulfide sensor are output by two independent circuits and are controlled and displayed by control and display software; and the device can go deep into a drainage pipeline together with the pipeline detection equipment and can be used for in-situ detecting the concentrations of the combustible gas and the hydrogen sulfide in the pipeline, thereby supplying a reference to pipeline entrance of workers, a part of non-excavation technical constructions, the deduction for waterpower condition and biochemical reaction in pipelines, and the like.

Description

Technical field

[0001] The present invention relates to the technical field of gas detection, in particular to a toxic gas in-situ detection device for drainage pipeline detection equipment. Background technique

[0002] During the operation of the drainage pipeline, if the sewage flow rate is slow, blocked, stagnant or stagnant, the sewage cannot be discharged in time, which will easily lead to an anaerobic reaction in the pipeline, producing methane, hydrogen sulfide and other toxic gases, which will cause workers Poisoning accidents occurred during well inspection and workers' work.

[0003] Existing gas detection methods mostly use portable gas detectors to detect the concentration of toxic gas in the pipe at the wellhead or through a small suction pump. This method is limited by the effective measurement range of its own instrument itself, and can only detect the concentration of toxic gas in the pipeline, and cannot understand the actual situation of each pipe section in the...
