Telescopic pipeline flow generator

Abstract

The invention relates to a telescopic pipeline flow generator, and belongs to the technical field of new energy and pipeline monitoring. A shell is installed on the inner wall of a pipeline through aspoke plate; an end cover is installed on the end part of the side wall of the shell; a left pin and a right pin are arranged at the left and right sides of the vertical plate of a bracket; transverseplates with inclined installation surfaces are arranged at the right sides of the upper and lower ends of the vertical plate; the bracket is arranged in the shell; therefore, the left pin extends outthrough the bottom wall of the shell; a bluff body is arranged on the end part of the left pin; a support spring and a buffer spring respectively sleeve the left pin among the bottom wall of the shell, the bluff body and the vertical plate of the bracket; a left spring, an exciter, a frequency modulation block and a right spring sequentially sleeve the right pin from left to right; the exciter isconnected with the frequency modulation block; the right end of the right spring abuts on a stop block on the end part of the right pin; both the upper and lower sides of the exciter are each provided with a movable cam composed of a bottom surface, an inclined surface and a top surface along the axial direction of the pin hole; one end of a piezoelectric vibrator is installed on the installationsurface of the bracket; when non-working, the flange of the substrate of the piezoelectric vibrator is contacted with the midpoint of the inclined surface of the cam; furthermore, the assembly pre-bending deflection is one half of the allowable value thereof; and the allowable deflection of the piezoelectric vibrator is greater than the lifting stroke of the cam.

Description

technical field [0001] The invention belongs to the technical field of new energy and oil and gas pipeline monitoring systems, and in particular relates to a telescopic pipeline flow generator. Background technique [0002] During the operation of oil and gas pipelines, oil and gas pipeline leakage incidents occur frequently due to natural corrosion, force majeure of nature, especially man-made theft, which not only caused huge economic losses, but also caused serious pollution to the surrounding natural environment. In the past, it was maintained by manual inspection methods, but because the pipeline laying distance is long, and it is often in an inaccessible or inconvenient place, it is difficult to detect leakage in time and repair it in time, so people have proposed various types of pipeline leakage monitoring or anti-theft systems. , some technologies are relatively mature; but the power supply problem of the oil and gas pipeline monitoring system has not been well reso...

Problems solved by technology

[0002] During the operation of oil and gas pipelines, due to natural corrosion, natural force majeure, especially man-made theft, oil and gas pipeline leakage incidents occur from time to time, which not only caused huge economic losses, but also caused serious pollution to the surrounding natural environment.

In the past, it was maintained by manual inspection methods, but because the pipeline laying distance is long, and it is often in an inaccessible or inconvenient place, it is difficult to detect leakage in time and repair it in time, so people have proposed various types of pipeline leakage monitoring or anti-theft systems. , some technologies are relatively mature; but the power supply problem of the oil and gas pipeline monitoring system has not been well resolved: the cost of laying cables is high and it is easy to be cut off by criminals, which will affect the normal operation of the monitoring system. Frequent replacement, once the battery is low and not replaced in time, the remote transmission of monitoring information cannot be completed
