Abstract

The invention relates to a self-powered device for monitoring oil and gas transmission pipelines and belongs to the field of oil and gas pipeline monitoring and power generation. A body is fixed on a boss inlaid with a bearing and arranged on the outer side of a pipeline, a press plate inlaid with a bearing is mounted in the body, the upper ends of columnar magnets enter large round holes at the upper end of the body through guide holes on the press plate, the lower ends of the columnar magnets are adhered with a group of bowl-shaped piezoelectric transducers arranged in small round holes, a spindle is mounted on inner rings of the bearings, blades are mounted at one end of the spindle, T-shaped magnets are inlaid on a flange plate which is welded at the other end of the spindle, and the T-shaped magnets and the columnar magnets are mounted with like poles close to one another. The self-powered device for monitoring the oil and gas transmission pipelines has the advantages that the piezoelectric transducers are used for converting oil and gas kinetic energy into electric energy, and reliable and sufficient energy can be obtained without laying cables or batteries; the self-powered device is high in power generation capacity, free of contact impact and noise and high in reliability; and power generation is determined by magnetic field intensity, and the self-powered device has high power generation capacity when the spindle rotates at a high speed, at a low speed and at a uniform speed.

Description

technical field [0001] The invention belongs to the technical field of oil and gas transmission pipeline monitoring and power generation, and in particular relates to a self-powered device for oil and gas transmission pipeline monitoring. Background technique [0002] During the long-term service of oil and gas pipelines, leakage incidents occur frequently due to natural corrosion, force majeure of nature, and especially man-made theft. Frequent pipeline leakage not only causes huge economic losses, but also causes damage to the surrounding natural environment. severe pollution. In the past, regular manual inspections were often used for maintenance. However, due to the long laying distance of oil and gas pipelines and the fact that they are often located in inaccessible or inconvenient places, regular inspections are difficult to find leaks and maintain them in time. Therefore, various types have been proposed for pipeline leakage monitoring or anti-theft systems, such as ...
