| titleOfInvention | A kind of buried oil gas pipeline wiper magnetic anomaly normal open ball monitoring and blocking localization method |
| abstract | The invention belongs to pipe-line to clear up field, and in particular to a kind of buried oil gas pipeline wiper based on the detection of single shaft fluxgate magnetic anomaly leads to ball monitoring of working condition and blocking accurate positioning method.Concrete methods of realizing is that permanent magnet group is installed on wiper, by weak magnetic detector at earth's surface monitor magnetic fluctuation be used to judging wiper whether normal through；When wiper blocking, search location pipe cleaner position along pipeline blocking section using weak magnetic detector array and it is instructed to excavate.Lead to ball monitoring in the present invention easily to operate with blocking location implementing method, use cost is cheap, can effectively avoid causing environmental pollution and influence enterprise employee health, position fast accurate, remarkable in economical benefits. |
