Sealing cabin for electronic devices in pipeline operation equipment

The utility model discloses a sealing cabin for electronic devices in pipeline operation equipment, which belongs to the field of natural gas transportation. The sealing cabin comprises a dynamic seal pressure-resistant cabin cylinder, a small pressure-resistant cabin cylinder and a large pressure-resistant cabin cylinder which are fixedly connected in sequence. An output shaft is installed on the dynamic seal pressure-resistant cabin cylinder; one end of the output shaft extends into the dynamic seal pressure-resistant cabin cylinder and the other end of the output shaft extends out of the dynamic seal pressure-resistant cabin cylinder; a dynamic seal O-ring is arranged at a position of the output shaft contacting with the dynamic seal pressure-resistant cabin cylinder; the small pressure-resistant cabin cylinder is used for installation of a power system; and the large pressure-resistant cabin cylinder is used for installation of electronic components. The sealing pressure-resistant cabin has the advantages of simpleness in structure, convenience to install and maintain, and capabilities of achieving static seal and dynamic seal of a rotary shaft and a reciprocating shaft and guaranteeing pipeline operation equipment, such as pipe cleaners, magnetic flux leakage detectors and pipeline robots to work safely and reliably.
